The epidemiological relationship of hypercholesterolemia, hypertension, diabetes mellitus and obesity to coronary heart disease and atherogenesis.
Coronary heart disease (CHD) is an imprecise, inappropriate monitor of atherosclerosis severity and by inapplicable extrapolation CHD risk factors are incorrectly assumed to be causes of atherosclerosis. Taking into account (1) the misuse and substantial diagnostic error of CHD, (2) errors in determining the prevalence of risk factors, (3) the use of a young non-representative minority of sufferers of CHD, (4) bias posed by inclusion of familial hypercholesterolemia (FH) in clinical studies and (5) mutual inter-relationships, genetic influence and age dependence of hypercholesterolemia, hypertension, diabetes mellitus and body mass or obesity, it is unlikely that multivariate statistical analyses can adequately differentiate between their effects. These factors are age dependent and so are CHD and atherosclerosis. The importance of hypercholesterolemia in atherogenesis is suspect particularly since the vascular pathology of familial hypercholesterolemia and of cholesterol-fed animals has been misrepresented and does not provide support for the role of hypercholesterolemia in atherogenesis.
