Should Low-Risk Patients Take Statins? A Critical Review

Dr. Kumar’s Take:

Many people are prescribed statins to lower cholesterol and reduce the risk of heart attacks and strokes. But do these drugs actually help those who have a low risk of heart disease? A recent review challenges the routine use of statins in low-risk patients, revealing minimal benefits but significant side effects like muscle pain and increased diabetes risk.

Actionable Takeaway:

If your doctor suggests statins but your 10-year heart disease risk is under 20%, ask about lifestyle changes first. A Mediterranean diet, exercise, and avoiding smoking may provide similar or better protection without the side effects.

Is Coronary Artery Calcium Testing the Best Way to Decide on Statins?

Dr. Kumar’s Take:

A recent study from the Multi-Ethnic Study of Atherosclerosis (MESA) suggests that coronary artery calcium (CAC) testing can help doctors make better decisions about who should take statins. Instead of giving statins to all intermediate-risk patients, CAC testing allows doctors to focus treatment on those who truly need it, potentially reducing unnecessary medication use and side effects.

If you’re at intermediate risk for heart disease, getting a CAC test could help you and your doctor make a more informed decision about statin therapy. It may be a cost-effective way to prevent heart disease while avoiding unnecessary medication.

Should You Take a Statin if Your LDL is High on a Low-Carb Diet?

Dr. Kumar’s Take:

This study challenges the long-held belief that LDL-C (low-density lipoprotein cholesterol) is always harmful. The authors argue that in the context of a low-carbohydrate diet (LCD), high LDL-C may not be a sign of increased cardiovascular disease (CVD) risk. Instead, they suggest looking at other markers—such as insulin resistance, triglyceride-to-HDL ratio, and coronary artery calcium (CAC) score—before deciding whether statins are necessary.

For those on an low carbohydrate diet with high LDL-C but otherwise good metabolic markers (low triglycerides, high HDL), this study suggests that statins may not provide the same benefits as they do for those with high LDL-C caused by poor diet and metabolic disease.
