Serum lipids and latent coronary insufficiency

Area of Science:

• Cardiology
• Clinical Lipidology
• Preventive Medicine

Background:

• Coronary heart disease (CHD) remains a significant global health concern.
• Early detection and risk factor identification are crucial for CHD prevention.
• Serum lipid profiles, including cholesterol and triglycerides, are established biomarkers for cardiovascular risk.

Purpose of the Study:

• To investigate the association between serum lipid levels (cholesterol and triglycerides) and the presence of coronary heart disease (CHD) in a cohort of 'healthy' men.
• To identify potential correlations between clinical and angiographic findings and serum lipid concentrations.

Main Methods:

• Clinical examinations, resting and exercise electrocardiograms (ECG) were performed on 2014 men.
• Serum cholesterol and triglyceride levels were measured.
• Coronary angiography was conducted on a subset of participants suspected of CHD.
• Lipid values were analyzed in relation to clinical signs, symptoms, and angiographic results.

Main Results:

• 7.0% of participants (140 men) were suspected of CHD based on clinical evaluation.
• Coronary angiography revealed pathological angiograms in 3.4% of the total cohort (69 men).
• Men with pathological angiograms exhibited significantly higher serum cholesterol and triglyceride levels compared to those without CHD signs.

Conclusions:

• Elevated serum cholesterol and triglycerides are significantly associated with the presence of coronary heart disease.
• Lipid profiling, alongside clinical assessment, can aid in identifying individuals at higher risk for CHD.
• Further research is warranted to standardize lipid measurements and account for influencing factors like alcohol consumption.
