OBJECTIVE: Our objective was to study prognostic factors for death in patients with coronary heart disease (CHD), focusing on serum lipids and lipoproteins. DESIGN AND SUBJECTS: The study subjects were 964 patients with angina pectoris who underwent coronary angiography between 1985 and 1987. Follow-up, including survival and cause of death, was carried out in April 1998. RESULTS: A total of 363 patients died. Increasing age, diabetes and low levels of HDL cholesterol and of apolipoprotein (apo) AI were associated with increased risk of total mortality and cardiac mortality. In men, low levels of LDL cholesterol and of apoB were associated with increased risk of death, but not of cardiac death only; high levels of lipoprotein(a) [Lp(a)] were not associated with increased risk. In women, however, there was a trend towards increased risk with increasing Lp(a) levels (P = 0.054); the smallest isoform of apo(a) was associated with a twofold increase in risk. In women, but not in men, risk decreased with increasing molecular weight of the apo(a) isoforms. CONCLUSIONS: Amongst lipoprotein variables, low levels of HDL cholesterol and of apoAI and the presence of low-molecular weight isoforms of apo(a) are associated with increased risk of death in patients with CHD. Apo(a) isoforms and Lp(a) levels seem to be more important as risk factors amongst women. Low LDL cholesterol and apoB levels were associated with increased risk, but only in men. These findings demonstrate the importance of a gender-specific analysis of risk factors for CHD.
