Serum lipids and latent coronary insufficiency.

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.
