What is Coronary Calcium Score? | Video

Video: This video illustrates the importance of Coronary Calcium Score, when to consider and how to interpret the results.

Coronary Artery Calcium, or CAC score, is a valuable test to estimate the future risk of a heart attack. I will discuss the pros and cons of this test and how it can be helpful or harmful if ordered and interpreted inappropriately.

 For decades, investigators have been trying to discover the “risk factors” that increase the likelihood of heart attack. Many risk factors have been identified through years of intensive and elegant research [1], including Smoking, Obesity, a sedentary lifestyle, high blood pressure (hypertension), positive family history of heart attack, menopause, inflammatory diseases like rheumatoid arthritis, and last but not least, Diabetes. Many studies have proven that we can significantly reduce the risk of heart attack by modifying these factors.

Despite these massive efforts and discoveries, still, many individuals suffer from a heart attack prematurely without having any or only a few of these risk factors. This fact suggests that our current risk calculators, developed based on “traditional risk factors,” are far from perfect. They can potentially miss many “preventable” cases of heart attack.

During the past 15 years, coronary calcium score has emerged as a reliable “predictive” test to further refine someone’s risk of future heart attack by identifying atherosclerosis.

Plaques are the main precursors of myocardial infarction. Atherosclerosis is an inflammatory process in the arterial wall that starts at a young age and is the primary driver of the “plaque” formation in the arterial wall. As we age, the process of calcification begins within the plaques. We can then identify the calcium in x-ray images, confirming the presence of an underlying plaque.

High cholesterol levels (Hypercholesterolemia), familial (FH) or non-familial, is a significant risk for early-onset coronary artery disease and atherosclerosis.

If you have high LDL-cholesterol levels, particularly at a young age, utilizing an “online FH calculator” can provide valuable insights into whether your hypercholesterolemia is genetically inherited. To learn more about hypercholesterolemia, check our article about Familial Hypercholesterolemia and the stepwise approach to a case of severe hyperlipidemia.

Figure 1: This CT scan, which belongs to a 60-year-old asymptomatic man, shows significant calcification of the LAD and RCA arteries. It implies that under this bulk of calcium, the process of “atherosclerosis” is progressing fast, which, if not controlled, can result in acute coronary syndromes (heart attack). 

He was initially labelled as “low-risk” based on traditional risk factor calculations. But this mere new fact (high coronary calcium score) will change his previous “low risk” status to “high-risk.”

When should you consider checking your calcium score?

There has been significant debate as to what clinical situation a coronary calcium score should be considered. CAC Score is a preventive test and should not be used in symptomatic patients (if someone has chest pain or shortness of breath). It is another piece of the puzzle to shed more light on someone’s “future risk of a Heart Attack”. 

Before considering a calcium score, it is crucial to calculate the patient’s baseline risk of a heart attack. Many online calculators like this online calculator from the American College of Cardiology can do this. It needs a few baseline information like the presence of Diabetes, Hypertension or high cholesterol levels. Smoking status, age and medications are other components. Based on this information, a 10-year risk estimate is generated. The patient will be categorised as low-risk, intermediate-risk, or high-risk for future heart attacks. 

To illustrate how the CAC score check can be helpful, here I present a typical case.

CASE: A 55-year-old man presents to you after his close friend suffered a massive myocardial infarction. They have been colleagues and used to exercise regularly with weekly swimming, cycling, and running regularly and intensely. He does not smoke, eats healthy, and has no significant family history of ischaemic heart disease. His cholesterol is on the low side, and he has mild hypertension, which is well-controlled with a low-dose antihypertensive. He is not complaining of any symptoms indicative of angina. He insists that his friend had the same profile and was at low risk for myocardial infarction. In this scenario, a test that can add significant weight and information to stratify his risk for future IHD is a coronary calcium score. He performs a CAC score, which comes back as 300. A calcium score at this level will immediately move him from the low-risk category to the moderate-high-risk category. He will undoubtedly benefit from intensive reduction of his LDL to 1.4-1.6 mmol/L and the addition of Aspirin.

This case illustrates that coronary calcium score should only be considered in individuals with “low to intermediate” baseline risk. A high coronary calcium score can modify someone’s low-risk status to high-risk, but a low or even zero calcium score does not change the status of a high-risk patient to low-risk. We should remember that A “high-risk” individual will remain “high risk” regardless of their calcium score. They should be on intensive therapy with Statins, Aspirin and encouraged to change their lifestyle rather than checking their calcium score.

What is the ideal age to check coronary calcium score?

Coronary Calcium test should be considered in individuals between 45-70 years of age. This does not mean those below 45 or above 70 cannot have the test, but the interpretation of the results should be guarded. Under 40, there has not been enough time for the lipid-rich plaques to calcify, and we can miss them on imaging as we can only see them if they are already calcified. For example, a young patient with familial hypercholesterolemia could have many “coronary plaques” at 30. Still, their CAC score could be zero, as no calcium has yet formed in the plaques. This can be misleading and result in “false reassurance”. However, a high calcium score in a young patient is highly concerning and should be taken seriously. It indicates that they already have formed coronary plaques with an increased risk of future IHD.

Above 70, nearly everyone has calcification of the coronary arteries. An elevated calcium score in the elderly, unless “significantly” elevated, does not necessarily indicate “high risk”. However, a low or0 calcium score in this age group can be extremely reassuring.

Therefore rather than concentrating on the “absolute” number of the calcium score, you should see where you stand compared to the people your age. By incorporating the “age factor” in our calculations, we reach a “percentile”, which is much more accurate in risk assessment compared to the “absolute” number. The MESA CAC score calculator is an excellent tool in this regard.

How should we interpret a calcium score of 0?

Coronary artery Calcium Score Coronary calcium score should always be interpreted in the context of other risk factors and never solely. As a calcium score of 0 in a low-risk patient is highly reassuring, the same score in someone who smokes and has high cholesterol or diabetes, is much less predictive of the risk. Any other diseases (risk factors) should be treated diligently, regardless of the coronary calcium score. Even with a calcium score of 0, patients should be counselled regarding smoking, treated for hypercholesterolemia, hypertension, and diabetes and encouraged to exercise regularly and eat healthily. 

To show the importance of this point, I have briefly discussed two cases of “severe coronary artery disease despite a calcium score of zero” in a separate post. Hopefully, these cases will explain why we can’t call a calcium score of zero, “normal”, without considering the patient’s age and other risk factors. 

How should a high calcium score be interpreted?

We know that Coronary calcium score must be interpreted according to age. A calcium score of 20 in a 70-year-old is considered low and excellent but significantly elevated for a 40-year-old. Many online charts show the risk according to the calcium score. However, interpreting the calcium score results is not as simple as looking at a chart and coming up with an answer. Many factors are involved in this process, and each result should be interpreted individually according to the patients, age, risk factors and likely complaints.

A calcium score above 300-400 is significantly elevated at any age. These patients require tighter control of their risk factors, Aspirin in certain cases and intensive cholesterol-lowering medical therapy, including statins, non-statin oral treatments like Ezetimibe and Bempedoic Acid and PCSK9 inhibitors and Inclisiran. Knowing their “high” risk motivates patients to be physically more active and follow a healthy diet. However, a high calcium score must never initiate the process of looking for “blockages” in coronary arteries or end up in angioplasty if the patient is “truly” asymptomatic.

Should the calcium score test be repeated in future?

Generally, if the calcium score is high, there is no need to repeat the test. A high score means the patient’s risk of ischemic heart disease is elevated, and they need intensive treatment of their risk factors and lifestyle modifications, and there is no need to repeat the test. A high-risk patient will remain high-risk, regardless of the future CAC scores. 

Select patients with a calcium score of 0, especially younger individuals, could consider repeating the test in 5 years, particularly if they have a few risk factors like high cholesterol or blood pressure and decide against medical therapy.

Is a calcium score test required for someone already on a statin?

The answer generally is no, but it depends on the case. A CAC test is not required if the patient is taking their medicine regularly and their LDL is around 2 mmol/L (77 mg/dl). However, if they are taking statin sparingly, and LDL is way above 2 mmol/L, we can consider a CAC test to guide the therapy. A more lenient approach towards medical therapy can be taken if the score is 0 or very low and vice versa. In the following video, I present a real case and show how Coronary Calcium Score can change someone’s cardiovascular risk profile and how it can be helpful or harmful.

Frequently asked questions:

How is coronary artery calcium measured, and how much does it cost?

What is a normal calcium score?

  • At any age, a calcium score of 0 is considered optimal and normal. This score indicates that no “calcified” plaque is present in the coronary arteries, a positive sign for heart health. However, it is crucial to remember that a calcium score of 0 may not tell the whole story. If “non-calcified” plaques are present, the score will still be 0, providing a false sense of reassurance. This limitation is a critical aspect to consider when evaluating the results of a coronary artery calcium scoring test.

Can I reduce or reverse my calcium score?

  • A calcium score indicates one’s future risk of experiencing a heart attack. If the score is elevated, it is crucial to focus on strategies to reduce the overall risk of cardiovascular disease rather than fixating on the “number” itself. Effective methods for risk reduction include quitting smoking, engaging in regular exercise, maintaining a healthy diet, and, depending on the score and cholesterol levels, potentially using statin therapy.
  • It is worth noting that your calcium score might increase after initiating statin therapy and incorporating exercise into your routine. This increase is not necessarily a negative development, as it could indicate that plaques are hardening and becoming more stable, subsequently reducing the risk of a heart attack. For further information, watch this video, Coronary Calcium Score: How to Interpret.

Can an echocardiogram detect coronary calcium?

  • An echocardiogram is a diagnostic test that utilizes ultrasound waves to create images of the heart, providing valuable information about its chambers, valves, and overall function. However, an echocardiogram does not directly visualize the coronary arteries or reveal the presence of calcification in these vessels.

Can stress tests detect the coronary calcium score?

  • No. A stress test or Stress echocardiogram is a diagnostic examination that evaluates exercise tolerance and can help detect coronary artery narrowing or blockages. This test utilizes ultrasound waves, similar to standard echocardiograms, but it is not designed to identify coronary calcifications. A stress test is a distinct type of investigation and is not comparable to a coronary calcium score test. These two serve different purposes and provide unique insights into an individual’s heart health.

Does CT Coronary Angiogram show calcium score?

  • Many radiology facilities automatically include calcium scores in CT Coronary Angiogram (CTCA) reports, but some may only provide them if specifically requested. To ensure your report contains a calcium score, ask your doctor to request it alongside your CTCA. For further insight into the differences, limitations, and indications of CTCA versus CT Calcium Score scans, review the article “CT Coronary Angiogram vs. CT Calcium Score: Differences, Limitations, and Indications.”

If I can have a CT Coronary Angiogram that includes the calcium score, why should I only do a calcium score?

  • CTCA and CT calcium scores are separate tests we use in different scenarios. We generally perform CT Coronary Angiogram (CTCA) in individuals experiencing symptoms suggestive of coronary artery disease (CAD) or having inconclusive stress test results. The CTCA allows for detailed visualization of the coronary arteries to identify any potential blockages or narrowing that could be causing these symptoms.
  • On the other hand, we only use the CT Calcium Score for risk assessment in asymptomatic individuals with low-intermediate risk factors for CAD. This test helps determine the presence and extent of calcified plaque in the coronary arteries—an indication of atherosclerosis that raises the likelihood of future cardiac events. Please refer to the article CTCA vs CT Calcium Score to learn more.

CAC score is only "one" piece of the puzzle

The coronary artery calcium score is only one piece of overall risk factor puzzle. Like any other test in medicine, it has pros and cons, can be helpful or harmful and should be used judiciously. It clarifies someone’s risk for future ischaemic heart disease and should never be interpreted solely without having the whole picture in mind. It should never be used to investigate chest pain and should not be ordered in high risk patients.

I am a 61 year old male and have just done a CAC test with a result of 1624. i do not have a Doctor but use an online service as do a lot of us in Canada due to the shortage of Doctors. I do not have any symptoms of heart trouble, am a non smoker and not overweight. My cholesterol has been on the upper limit for the past 5-6 years but i`m hoping some better diet changes i have made may help with that. The Doctor did not seem concerned paticularily but recommended good diet and exercise. She did not pursue any further tests. With this extremely high score should i be pushing to get more testing done? She did not see any benefit to putting me on statins. I had an echocardiogram recently which did not show any major problems. I have no family history of heart disease. How would you recommend i move forward with this. Best regards.

Hi Doc,
I really appreciated your article, this helped me understand how to look at results. That being said, I’m a 40 year old white male with a long family history of heart disease. My father suffered a heart attack at 43, and his father at age 40. Ex-smoker but do still use nicotine. Exercise nearly every day, protein shake for breakfast, salad for lunch every day. My CAC was 32, all in the LAD (my dad’s heart attack was a widowmaker, of course). My bloodwork has always been normal, BP is great, no real health issues other than anxiety. I was concerned with being in the 89th percentile and plan to follow up with a cardiologist, but appreciate any advice/insight you can give. Thanks in advance, and thanks again for the information you’ve shared here.

Hello Doc,

I am 43 year old Indian Asian physically active.I have a family history of Heart Attack. My brother passed away in young age due to heart attack.I am doing calcium scoring every 5 years from last 15 years and score is 0. I am also going stress test and echo every 2 years and all good. Last calcium scoring scan I did 5 years ago and score was 0. I am worried about radiation so should I continue pattern of repeating every 5 years. My total cholesterol is always below 200 but LDL is always around 120-130 range. What do you recommend.

I’m a 59 year old male, 5’10” 83kgs, former smoker, pescatarian diet for the last 7 years and my score in 2021 was 2! I have high cholesterol (6.4) which I suspect is hereditary so my GP recommended another scan which I had yesterday, it’ll be fascinating to see the result. I concur with others here, excellent site!

Hi, sincerely appreciate the information you’ve shared. I recent was pulled off my statin because of muscular loss/concern. I’m a 62 yr old male, play and walk 18 holes of golf 3 days a week, eat normal, drink beer, and have a family history of heart disease. I’m 5’9” and weigh 175 lbs. My general practice doctor pushed me to do a Heart Scan, and the results are frightening and wondering how concerned I need to be. My score was 911, and they found two 3mm noncalcified nodules on my left lung. I’ve reached out to a Cardiologist at the Cleveland Clinic and planning to make the trip in the coming weeks. Wondering how concerned you would be if you were me. Thank you …

I found your information easy to understand and I will keep using your site when I need medical explanations.

I am a 52 year old female, 5’0″, 107lbs., that works out faithfully every day. I run every morning, complete cardio-intense workouts 3 days a week and midweight training + cardio 2 days a week at lunch, and I squeeze in heavy weight training in the evening 2 days a week. I rarely eat red meat, choosing lean grilled chicken and omega-rich fish on the regular.

I became a T1 diabetic 4 years ago 3 months after my doctor prescribed a statin and I started statin therapy for cholesterol reading of 216 (hereditary coronary issues SUCK).

I will never use a statin again. It caused my pancreas to fail, tendon pain, muscle cramping, fatigue, and a schlew of other issues in my body. Statins are of the devil, in my opinion.

My cholesterol has risen since stopping the statin. Prior to taking it, I was steady between 190 and 216. Now it’s 300. I asked my PCP to prescribe Nexletol first, but it was not covered by my insurance. I asked her to prescribe Zetia, which happened to be covered by my insurance. I started taking it last night.

Prior to starting the Ezetimibe (Zetia) script, My PCP ordered a CAC, which took place this morning and came back with a score of 218. I’ve ordered OTC Cholestamin, and together with the ezetimibe, I’m hopeful to have some sort of control. It’s so frustrating when I’m doing everything right and due of hereditary issues, my health is teetering on a thin line.

Any suggestions you can offer would be appreciated.

Hi Doctor. This was very enlightening. I am 71 years old and just received the following from my calcium scan: Left Main = 0, Left Anterior Descending = 100, Left Circumflex = 13.6, Right Coronary Artery = 0, Total Agatston Score = 114. That seems OK for me?

I am white male, 43 years old, non smoker and exercise regularly. I had a CT scan due to family history, and have a score of 51. The doctor indicated that no lifestyle changes or medication is needed, as I am typically considered low risk- but judging by your article it’s actually quite high for someone in my age group. Keen to understand if I should seek a second opinion

Hi. Thank you for the very informative article, video and moderating this blog.

I’m an active 57 year old male, who runs and gyms regularly with a BMI 24.0 & resting heart rate of 45-50. I value good lifestyle choices. I have a good diet, am a non smoker & light social drinker.

In 2018 (at 52 years old) I experienced heart palpitations while kayaking and had my first CT CAC test with the result of 420 with 400 in the LAD artery. The report placed me in the 97 percentile for my age and sex.

I was placed on Ezetimibe 10mg & Rosuvastatin 5mg to manage my cholesterol. At the time TC was 7.9, LDL 4.86, HDL 1.89, TG1.0. I was also placed on 100mg Asprin and referred for a Stress Test.
The test results were good with 11:40min to achieve max workload of 17.3 METS which the Cardiologist commented was “excellent”.

I have had stress tests every 2 years since, with the last stress test in May 2023 showing similar results and my cholesterol is now down to TC 4.2, LDL 1.93, HDL 1.86 & TG 0.9.

Given the improved cholesterol and consistent stress test results my Cardiologist referred me back to my GP for good. He felt I didn’t need any further stress tests and can just stick to the current management plan.

I asked my GP if I could stop taking Asprin now I was on top of things and he suggested doing a follow up CAC to see if things had stabilised.
The result was 730 with 664.3 in the LAD. I was a bit shocked to say the least. I incorrectly assumed the reduced cholesterol & continued exercise would slow or stabilise the calcium build up in my heart. I didn’t expect it to almost double in 5 years.

I’ve been referred back to my Cardiologist who I will see in early Nov. I’m asymptomatic and assume he wont want to do anything invasive until I’m displaying symptoms.

I will obviously ask him these questions but would also value your opinion please.
Is the high score in the LAD in particular a concern? At the rate of build up over the past 5 years, I assume this keeps climbing until one day in the future I’ll display symptoms or experience an event?
Is there anything else I can do to slow, stop or reverse this trend?
Does Vit K-2 (Mk7) help? I’ve read it can improve calcium absorption in the bones and possibly reduce deposits in the arteries?
Given the increasing build up is there any benefit to an angiogram to see what % of the LAD is blocked?
I am adopted so have no family history to refer to. I have no other health issues.

Thanks for the detailed answers but I wanted to ask a follow-up. I am in a similar boat with calcium score of 287, 270 in LAD., I am a 60 year old male, good fitness and eating habits since my parents both had coronary issues and type-2 diabetes. Can you address the issue of a high LAD calcium in relation to other coronary arteries. Sounds scary since LAD blockage is supposed to be the most serious.

I’m a white, male, age 67 who’s father did have a heart attack. I smoked for 20 years but haven’t smoked in the last 20 years. I did have some chest pains and the doctor put me on high blood pressure medicine and ordered a stress test. All my blood work is good, but my calcium score was 30. The doctor wants to “go in” and check to see if i need a stent and do it while he’s “in there” if needed. Is this a normal, recommended procedure in this case?

Bless you for publishing this column. I’ve learned more from this one website than years and years of trying to understand. I am 72 and have just had my third CT scan, probably it was unnecessary as I was already above normal 12 years ago with scores around 350, 6 years ago with scores around 450, and now scores in the 600s. The most important thing I have learned from reading this column is that there is not a straight line correlation between these scores and the actual amount of plaque. Also that someone totally asymptomatic and slim and athletic like me , is already doing most of what has to be done to stay healthy. You even clarified why statins would be helpful in stabilizing the plaque. So grateful. I was in a panic but now I am feeling more like a normal human being and I’m ready to do what needs to be done, and nothing more. Wish I had read this a few years ago. Thank you thank you thank you

At the outset, this article and video on this topic is second to none. Full stop.

I’m a 63-year-old male, 6′ 3″, 208 lbs. Exercise moderately. Diet is not rich in saturated fats, and I rarely eat red meat. My diet could be healthier. ECGs indicate presence of RBBB.

In November 2017, I requested CAC and scored 822. At the time my LDL was 4.02 mmol/L and total CHOL was 5.82 mmol/L Standard of care was 5mg of Rosuvastatin. LDL dropped to 2.31 in 2 months. In January 2020, I had another CAC with a score of 1225 and dosage was increased to 10 mg. Remarkably, my LDL has increased over time and remained in the 2.80 range. Lipid profile was in line with references in Canada. Glucose, HbA1c and insulin all within reference ranges.

In late June of this year, I was referred to a cardiologist when I had chest pain. He increased the dosage to 20 mg. Last week I underwent a stress echo, ABI, and vascular testing on the carotid, legs and abdomen. Results of the tests are pending. I have yet to have a lipid panel since the dosage increased, however, my goal is to reduce LDL to under 2.0 mmol/L by way of an improved diet, a more rigorous exercise program and a more aggressive statin therapy.

My question Dr. Moazzeni, is should I consider non-invasive CT angiography? Am I on the right path in general?

Thank you for comments Dr. Moazzeni. I neglected to mention that I have been taking daily aspirin since I started the statin in 2017.Moreover, I also failed to mention my Lp(a) result of 68nmol/L (reference is <1.00) and my Apolipoprotein B of 0.96 g/L (reference is <1.05). I will certainly continue to engage with my cardiologist. Thank you again

I’m a 56yr old male, 180cms tall and weigh 73kg (160lbs).
Very active, exercising most days either being cardio (bike riding), weight sessions and walking.

I had some blood work and as expected my overall cholesterol is high 8.1H mmol/L.
Triglycer = 0.6 mmol/L
HDLC = 2.50 mmol/L
LDLC = 5.3H mmol/L
LDLC/HDLC = 2.1 
Chol/HDLC = 3.2

As expected, the doctor wanted to put me on a statin which I refused but suggested that doing a CT Coronary Artery Calcium would be a good test to determine if the high cholesterol is really an issue as I follow a carnivore diet. Not strict but is 95% of my diet.

Well, the CAC score came back of 797 which really shocked me. I wasn’t expecting that.
With such a high score the risk is high of a heart attack.

Blood pressure is good, resting heart rate is in the mid 50’s, no diabetes.

So the recommendation is to change the diet and reduce saturated fats (fatty meat, diary) and start taking a statin (ATORVASTATIN) and Aspiran.
A diet change will be to introduce vegetables/fruit/healthy fats ie: avocado, olive oil, nuts
Not happy about that.

I feel good but this has really shocked me.

Any thoughts or suggestions to reduce the risk is appreciated.


I am 77 yo, 5’6″, 233#, status post RNY bypass 11/1998. Normal cholesterol levels (total 178). No diabetes. No pre-diabetes. Calcium score of 64. Three doctors have suggested I start statins. I am on no other medications (except Stelara for psoriasis). I eat well, exercise (3 modalities, 8x week). I am resisting starting statins because it seems their suggestions are from some formula the pharmaceutical companies have come up with. Am I misinterpreting this?

Hello, I am 42 years old. CT test showed that my calcium score is 7.7 and Eccentric calcified plaque of proximal segment with minimal stenosis. I wanted to know your opinion

What a great forum! I’m a 57 yr old male, 6’1, 247. I found out a week ago my calcium score was 300, I immediately started to assume I was gonna drop dead any day. But after alot of reading and this site, I have a much btr perspective on the issue and have stopped thinking I’m going to die any day from a heart attack! WHEW! ,Lol.. Istarted statin therapy and of coarse changed my diet, stopped drinking, exercising at the gym daily. Thanks to all.

I am a 57 year old white male who exercises regularly and eats a relatively healthy, though not perfect, diet. Today, I just received a total CAC score of 117 (113 of it from the left anterior descending). I am under the guidance of my physician and don’t have is evaluation of the results yet. Do you think a statin will be necessary?

Hi Dr.,
My husband is 73 ys old. He plays hockey 3 to 5 games per week and is active with yard work, cutting down trees, lawn mowing, you name it. I am several years younger and he works circles around me sometimes. My husband recently has been having groin pain issues and neck pain on and off (more on lately) and last time he was at the Dr. they suggested a cac test. Well he went for it and his score was 2215! I am terrified and we have an appointment in 10 days but it can’t come soon enough. The general practice dr says he hasn’t seen a score like that. Any suggestions while we wait? He has stopped playing hockey and I put a halt on all other activities, but he is an active person and not one to just sit around. By the way, your article was very informing. Thank you

hi I have recently been told i have a calcium score of 448 at 42 years old,, showing heavy burden of coronary artery atheroma but no significant stenosis, but a high Burdon of non obstructive atheroma, not really sure what all this means and should i be significantly worried

My husband is 41 and has a cac score of 58. He is otherwise healthy. The nurse at cardiology office said that was a perfect score, but I’m thinking she is wrong. He has minimal calcification in LAD. Would really appreciate another opinion. Thanks in advance

Iam a 66 year old woman with a CAC score of 225 with the split mainly in the right oronary and left descending. My primary care doctor order this test due high cholesterol/high blood serum. He had taken me off cholesterol med 7 months ago and of course will be putting back on it. My question is,
should I see a cardiologist at this point?

Hello Dr. I will be 44 in a month, 5,11.5 and 250 lbs. I just found out my calcium score was 446. I was beyond shocked, especially when I saw how few my age have scores even half that value. I am a little terrified. It feels like I have just been given a death sentence or at least told I won’t the next decade, let alone see my 70s and 80s. I don’t even know, if I shoud do any physical activity, like tennis, running, and calisthenics. I feel like I should have a defibrillator with me at all times a wearing a heart rate monitor. Anyway, I guess I am asking if i can still live a long time with a heart such as mine? Can I still be active in exercise and competitive sport? Im seeing my cardiologist in a few days, to talk about the result, but I am really panicking now. I cant stop crying actually.

Can you explain why you would look Lp(a) levels? What levels might reassure or be concerning? And when evaluating Lp (a) levels, what others lipid profile levels would be of interest in relationship to Lp (a)? Any ratios related to Lp(a)? Thank you for such an informative video and thoughtful responses in your comments section, learned from these too!

Hi Dr.

I am 57 and my CAC score was 1009 with most of that in my LAD. It is just one test, but should I be worried? I have the data, but have not yet spoken with my cardiologist. I workout every day, have high cholesterol, and have been eating healthier and doing more cardio as a result.

Thanks Doc! My cardiologist has scheduled a nuclear stress test and a lipid panel. I take Warfarin for a prosthetic, mechanical aortic valve, which I think has contributed to the calcium buildup. My doc wants me to take a statin, but I am wary of treating what may be the side effect of one drug with another drug that also has its own side effects. I will if I have to, but not until after my lipid panel.

BTW, this is a fantastic thing you are doing here!

I am 72 and have FH from my Father. I had my first Calcium Test in 2017, and last year had a 2nd CAC test plus a Heart Exercise Stress Test. All returned – ZERO (in fact the cardio specialist asked why I was there)!. I have never taken any statins and will not do any until a test suggests I should consider it. Seems that no-one has done any research that makes sense under these circumstances. I eat well and exercise often and I personally feel that the high cholesterol reading is just that my body is fine with it. Whilst it doesn’t yet put the cholesterol it where it isn’t wanted – I should not risk any affects from the statins.

I’m 60, my CAC score is 36. My doctor recommended going on a statin. According to this online calculator , I’m 32nd percentile for a white male like me. If I’m “better” than 62% of white guys, I can’t see going on a statin. Do you argee?

I am 64, my score is 919 and percentile is 92. Guess it is pretty high: no symptoms, daily vigorous exercise. Are the units used are all the same around the world?

Thanks, clear and logical explaination.

My score went from a zero to 32 in a span of 4 years. as a 60 year old male, should I be concerned?

very informative. Thanks

Thank you. Very informative!

This discussion and particularly the video was excellent. I have a family history of heart disease. Starting with my primary physician and the through screening programs offered by a local hospital I’ve had regular vascular, CT scans and calcium scores.

The results were interpreted for me by my primary physician, but frankly I never really understood what she was telling me. Your video was extremely helpful in understanding how plaque develops.

Have you made, or do you know of other videos related not the issues that I should understand related to “intervention” options that – base on my family history – will likely be needed at some point?

Great review of the subject and video, thank you

Is my high cholesterol genetic?
