[The serum triglycerides and their role as a coronary risk factor (author's transl)]
Insights
Simultaneous high cholesterol and triglycerides pose the greatest risk for heart attack and angina. Isolated high triglycerides showed no significant risk for coronary events.
Area of Science:
- Cardiology
- Lipidology
- Preventive Medicine
Context:
- Hyperlipoproteinemia, characterized by elevated lipids, is a known risk factor for cardiovascular disease.
- Understanding specific lipid profiles and their association with coronary events is crucial for risk stratification.
Purpose:
- To investigate the differential risk associated with various types of hyperlipoproteinemia and lipid elevations for angina pectoris and myocardial infarction.
- To clarify the role of isolated hypertriglycerolemia and specific hyperlipoproteinemia types as coronary risk factors.
Summary:
- A study of 291 hyperlipoproteinemia patients and 216 controls found Fredrickson Type IIb hyperlipoproteinemia posed the highest myocardial infarction risk.
- Simultaneous elevation of serum cholesterol and triglycerides was a significant risk for both myocardial infarction and angina pectoris.
- Isolated hypertriglycerolemia and Fredrickson Type IIa hyperlipoproteinemia showed no statistically significant risk for angina pectoris.
Impact:
- These findings highlight the greater significance of hypercholesterolemia compared to hypertriglycerolemia in coronary risk.
- The study provides evidence for refining cardiovascular risk assessment based on specific lipid profiles.
Abstract:
291 patients with various types of hyperlipoproteinemia and 216 persons with normal serum lipid levels were examined for the frequency of angina pectoris and myocardial infarction. As a risk factor of myocardial infarction, Fredrickson's Type IIb was ranking on top, followed by simultaneous elevation of serum cholesterol and serum triglycerides regardless of the lipid-electrophoretic tappern, followed by Fredrickson's Type IV and finally by isolated hypercholesterolemia and Fredrickson's Type IIa. For angina pectoris, the order was slightly different: the highest risk factor was the simultaneous elevation of serum cholesterol and serum triglycerides, followed by hyperlipoproteinemia Type IV, hyperlipoproteinemia Type IIb, and finally by isolated hypercholesterolemia. The risk of both myocardial infarction and angina pectoris caused by isolated hypertriglycerolemia was not statistically significant, the same observation was made for the risk of angina pectoris in hyperlipoproteinemia Tye IIa. The present results confirm that an elevation of the serum triglycerides plays a minor role as a coronary risk factor in comparison to hypercholesterolemia.
