Normal Cholesterol Does Not Guarantee Protection from Heart Attacks, Expert Explains

Someone with normal cholesterol levels may feel reassured. However, that does not fully protect a person from the potential of a heart attack.

A heart attack occurs when blood flow to part of the heart muscle is suddenly blocked, and cholesterol is only one factor. The American Heart Association (AHA) cites age, metabolic syndrome, and certain inflammatory conditions as factors that can influence heart attacks.

“Almost 60 per cent of all heart attacks occur in people with normal cholesterol levels,” said expert Dr Vasilly Eliopoulus in a post on his social media, as quoted from the Times of India.

“CEOs, professional athletes, investors, and people who generally appear healthy based on check-up results can still experience heart attacks,” he added.

The problem lies in what standard lipid profile tests actually measure. These tests generally focus on LDL cholesterol (“bad” cholesterol), HDL cholesterol (“good” cholesterol), and total cholesterol.

Although these numbers can provide a basic picture of health conditions, the results do not fully show the condition of blood vessels. Someone with ideal LDL levels remains at risk of dangerous plaque build-up that blocks blood flow and triggers a heart attack.

Dr Eliopoulus explained that controlling LDL alone is like looking at the surface of the sea and assuming we know what lies beneath it. According to him, arteries are not merely pipes that carry blood. Their inner lining responds to blood sugar pressure, cigarette smoke, and inflammation.

Persistent high blood pressure can damage artery walls. Diabetes and insulin resistance can also trigger processes that make atherosclerosis more likely. This is especially important for people who feel healthy because they have no symptoms.

Tips for Maintaining Heart Health

Here are four things that can be done to maintain heart health even when cholesterol test results are normal.

1. Do Not Assume Normal Cholesterol Means the Heart Is Safe

It is best to stop treating cholesterol levels as the overall picture of health. Blood pressure needs to be monitored regularly, as do blood sugar, physical activity, weight, sleep quality, and family history.

2. Adopt a Healthy Diet

A sustainable diet that includes vegetables, fruits, whole grains, nuts, and appropriate protein sources is more beneficial than chasing short-term diet trends. The AHA also recommends limiting foods high in saturated fat, added sugar, and sodium.

3. Physical Activity

Physical activity is important, even when weight loss is not the goal. Moving regularly can support blood pressure, metabolic health, and overall cardiovascular fitness.

4. Get Enough Sleep

Pay attention to sleep quality as well. The AHA recommends that most adults sleep around 7-9 hours each night.
