Serum lipids and latent coronary insufficiency
Insights
This study found that higher serum cholesterol and triglycerides correlate with coronary heart disease (CHD) in men. These lipid levels were significantly elevated in participants with pathological angiograms, indicating potential heart disease risks.
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.
Abstract:
A group of 2014 'healthy' men were examined clinically, by resting ECG/exercise ECG and by the estimation of serum cholesterol and triglycerides. On repeated collection of specimen, standardization of factors related to the individual and influencing serum lipids was difficult to obtain. Thus, serum triglycerides were higher early in the week, at least partly due to habits of alcohol consumption. 140 of the participants (7.0%) were suspect of coronary heart disease (CHD) according to their symptoms/signs, and coronary angiography in 105 of them showed sixty-nine cases (3.4%) with pathological angiograms. Values for serum cholesterol and triglycerides are presented from a subgroup of 1832 men where no signs of CHD were found. Serum cholesterol and triglycerides were significantly higher in the group with pathological angiograms.
