Abstract [en]

During the past decades the knowledge concerning risk factors and pathophysiology of coronary heart disease (CHD) has substantially increased. However, despite identification of important risk factors CHD remains the leading cause of death in the western world.

The metabolic syndrome is a cluster of metabolic disorders such as hypertension, hypertriglyceridemia, low HDL-cholesterol, and glucose intolerance associated with an increased risk of cardiovascular morbidity and mortality.

The studies in this thesis are epidemiological in their character, and examine the relationships between different aspects of CHD and the metabolic syndrome in a population-based study of middle-aged men (ULSAM).

The findings indicated that serum lipids were important risk factors for the development of both angina pectoris demanding revascularisation and acute myocardial infarction (MI). Proinsulin and blood pressure were independent predictors of MI only, suggesting these factors to be involved in thrombosis and plaque rupture.

It was also found that antihypertensive treatment with beta-blockers and thiazide diuretics resulted in increased fasting blood glucose concentrations in subjects with an insulin resistant state with elevated proinsulin concentrations. Both proinsulin concentrations and increase in fasting blood glucose were associated with increased risk of developing future MI.

The finding of a new Q/QS-pattern on the resting ECG, regardless of history of MI, was associated with impaired insulin secretion and was an independent predictor of total and cardiovascular mortality.

A risk prediction score for MI including proinsulin and the ratio between apolipoprotein B and apolipoprotein A1 was developed in middle-aged men. This score was predictive for future fatal and nonfatal MI, and proved to be at least as good as the Framingham and the PROCAM scores, being based on traditional risk factors.

In summary these studies provide further knowledge about the associations between CHD and the metabolic syndrome and the possible importance of new markers of cardiovascular risk such as proinsulin and the apolipoproteins.
