High LDL cholesterol levels are the primary risk factor for cardiovascular disease, according to a Health Chosun report.
While smoking is a well-documented threat to heart health, excessive levels of LDL cholesterol—often called “bad cholesterol”—can be more dangerous. When LDL levels are too high, the substance builds up on arterial walls to form atherosclerotic plaque. This buildup can narrow or block blood vessels, increasing the risk of myocardial infarction and stroke.
“LDL cholesterol levels being high is the biggest risk factor for cardiovascular disease,” said Norman LePage, an American cardiologist, as reported by Health Chosun.
Because high LDL levels frequently present no obvious symptoms, experts emphasize the necessity of regular blood tests to monitor levels.
Medical professionals warn that smoking should not be dismissed despite the heightened threat of cholesterol. Norman LePage said that smoking can significantly raise the risk of stroke, myocardial infarction, and peripheral artery disease. Severe peripheral artery disease can damage leg vessels and, in extreme cases, lead to amputation.
Continuous smoking also contributes to plaque accumulation in the coronary arteries and can negatively impact LDL cholesterol levels.
Managing LDL cholesterol requires specific dietary adjustments and physical activity. To maintain healthy levels, experts recommend avoiding trans fats found in fried foods and reducing the intake of foods high in saturated fats and sodium. Instead, individuals should incorporate foods rich in unsaturated fats, such as fish and avocado, into their diets.
Physical activity also provides measurable benefits for lipid management. The study analyzed data from 148 randomized controlled trials involving 8,673 participants to examine the relationship between exercise and blood lipids.
The analysis found that the group that exercised had LDL cholesterol levels that were, on average, 7.22 mg/dL lower than the control group.
| Method | Recommended Action | Impact/Detail |
|---|---|---|
| Dietary Fats | Increase unsaturated fats | Use foods like fish and avocado |
| Dietary Fats | Reduce trans and saturated fats | Avoid fried foods and high-sodium items |
| Physical Activity | Regular exercise | Reduces LDL by an average of 7.22 mg/dL |
