Insights
This study investigated cholesterol, lipoprotein, and triglyceride levels in Argentinian patients with coronary atherosclerosis. Results show elevated levels in younger patients and women, highlighting potential risk factors for heart disease.
Area of Science:
- Cardiovascular Medicine
- Clinical Biochemistry
- Epidemiology
Context:
- Coronary atherosclerosis is a leading cause of heart disease, with elevated cholesterol as a primary risk factor.
- Limited data exists on lipid profiles within the Argentinian coronary population.
- Understanding these levels is crucial for risk stratification and management.
Purpose:
- To determine the levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) in Argentinian patients with coronary atherosclerosis.
- To analyze these lipid levels based on demographic factors like sex and age, and clinical factors such as myocardial infarction history.
Summary:
- A study of 653 Argentinian patients with confirmed coronary atherosclerosis measured key lipid parameters.
- Mean levels were: TC 227 mg/dL, LDL-C 153 mg/dL, HDL-C 48 mg/dL, and TG 180 mg/dL.
- Significantly higher TC, LDL-C, and HDL-C were observed in women compared to men, and in younger individuals compared to older ones.
Impact:
- Provides essential baseline data on lipid profiles in Argentinian patients with coronary atherosclerosis.
- Identifies demographic subgroups (younger patients, women) with potentially higher lipid-related cardiovascular risk.
- Informs future research and clinical guidelines for managing dyslipidemia in this population.
Abstract:
Although coronary atherosclerosis is considered to have several etiologic factors there is little doubt that elevated plasmatic cholesterol level is the main one. The present study was carried out because of the lack of information concerning cholesterol, lipoproteins and triglycerides levels in the coronary population in Argentina. Patients were selected on the basis of a demonstrated coronary atherosclerosis, detected either by an abnormal coronary arteriogram or a documented myocardial infarction. Total seric cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglycerides (TG) were determined in a core laboratory. Blood samples were obtained after a 12 hour fasting period. LDL-C was also calculated by the Friedewald formula. Patients were stratified according to sex, age, having or not myocardial infarction, type (Q or non Q wave) and localization of myocardial infarction. A total of 653 patients were included. The mean values obtained were: TC 227 +/- 1.8 mg/dL; LDL-C 153 +/- 1.8 mg/dL; HDL-C 48 +/- 0.4 mg/dL and TG 180 +/- 3.6 mg/dL (expressed as mean +/- SE). Mean values in the male and female subsets are given in Table 1. In women, TC, LDL-C and HDL-C are significantly higher than in men. Cholesterol values according to age are displayed in Table 3. Young people have higher TC and LDL-C mean values than older ones. Different cholesterol levels were not observed when the coronary population in our study was stratified according to the presence or not of previous myocardial infarction (Table 4).(ABSTRACT TRUNCATED AT 250 WORDS)
