High good cholesterol number = no need for medication? medical myths debunked! If you have cholesterol problems, do not enter the danger zone

CNEWS Convergence News Network Correspondent Chen Junkai / Reporting from Taipei

There are many people in Taiwan who have cholesterol problems. Attending Physician, Department of Interventional Cardiology, Cathay Hospital Cardiovascular CentreHuang ChenyouI found that patients often think, “My bad cholesterol (LDL-C) is high, but my good cholesterol (HDL-C) is also high. Does this mean I don’t need medication?” to take?” On the other hand, they have entered the danger zone If patients with high cholesterol want to reduce or stop taking medication, they must first make a decision after a professional evaluation by a doctor.

Huang Chenyou, in medical research on cholesterol, said that we currently know much more about LDL-C than HDL-C. Many clinical studies have proven that excess LDL-C will increase the risk of vascular occlusion diseases such as myocardial infarction and stroke If LDL-C in the blood is reduced, the above risks can be significantly reduced.

To prevent cardiovascular risks, the LDL-C control goals vary according to individual risk.

Huang Chenyou pointed out that according to the latest guidelines, the LDL-C target for people with diabetes should be less than 100 mg/dl for severe coronary heart disease, carotid artery stenosis or arterial occlusion of the lower limbs. lower, it is recommended to be less than 70 mg / dl for those who have multiple myocardial infarction or patients with diabetes, it is recommended to be less than 55 mg / dl there

The most important thing is to note! Huang Chenyou emphasized that past epidemiological studies have found that HDL-C values ​​and cardiovascular risk are related to the face, but the causal relationship has not been established. In recent years, large, more accurate data analysis has shown that there is no significant correlation between HDL-C and lower cardiovascular risk, but low HDL-C often accompanies clinically high LDL-C. In addition, some new drug clinical trials have also found that increasing HDL-C alone without affecting LDL-C or apolipoprotein ApoB cannot reduce the risk of any cardiovascular events. , and cannot delay the progression of atherosclerosis.

Huang Chenyou said that a recent study published in the American Heart Association in 2024 found more than 10,000 patients with hypertension Compared with the group with HDL-C between 40 and 80mg/dl, HDL-C was higher than 80mg/dl and patients with HDL-C less than 40mg/dl have a higher chance of cardiovascular death, myocardial infarction and stroke. Therefore, more research is needed to clarify whether HDL-C is really a “good” cholesterol for the human body. The general public are reminded not to be superstitious about health foods, but are still concerned about medicines that are both safe and effective.
