- There are very few contemporary studies on the frequency and cause of congestive heart failure (CHF) in a general population. In western Sweden, inhabited by 1.64 million people, a retrospective survey was performed. All hospital records of patients with CHF, ages 16 through 65 years, were examined in all hospitals in the region. During the study period 2711 patients fulfilled the criteria for CHF or cardiomyopathy. Patients were monitored for 37 +/- 28 months. The most common cause of heart failure was coronary artery disease (IHD) (40%). Other common causes were hypertension (17%), valvular disease (13%), alcohol (11%), diabetes mellitus (10%), and systemic diseases (10%). There were positive correlations between the male sex and IHD, alcohol, and dilated cardiomyopathy; the female sex was associated with systemic diseases, valvular heart disease, and diabetes. The incidence of CHF requiring hospitalization per 100,000 in the population was 1.2 to 263 men and 1.1 to 129 women, in the youngest (age 16 to 30 years) and oldest (61 to 65 years) age groups, respectively. The 5-year survival rate was 50%. Analysis of causes performed with Cox's proportional hazards model for survival showed that age, IHD, alcohol, and diabetes were independent and powerful predictors of mortality (p < 0.001). The mode of death was progressive heart failure in 54% and sudden death in 26%. We concluded that the prognosis in patients with CHF was still very poor, even among this young population. The most common cause of CHF was IHD, and the second was hypertension.

- The influence of pre-operative serum lipid levels on late clinical outcome after coronary artery bypass surgery was analysed in 83 patients undergoing coronary bypass surgery for stable angina pectoris. The mean follow-up period for surviving patients was 105 +/- 33 months (range 65-133). Twenty-two patients (27%) had died during follow-up, of whom 14 had sustained a fatal myocardial infarction and four had succumbed to other cardiovascular causes. Thirty-one patients sustained 35 cardiac events, defined as either fatal or non-fatal myocardial infarction, or reoperation, or PTCA during the follow-up period. With univariate analysis, pre-operative serum levels of total cholesterol and triglycerides were significantly related to cardiac events, P < 0.05 and P < 0.05, respectively. In a Cox proportional analysis, cardiac mortality and total mortality were related to serum triglycerides and HDL cholesterol (P < 0.05 and P < 0.01 respectively). Eighty-five percent of the patients with triglycerides < 2.0 mM.l-1 survived for 10 years, while only 48% of patients with triglycerides > 2.0 mM.l-1 remained alive for that period. Figures were similar for subjects with HDL cholesterol > 1.0 mM.l-1 or HDL cholesterol < 1.0 mM.l-1, at 89 and 38%, respectively. Only 28% of the patients with the combination triglycerides > 2.0 mM.l-1 and HDL cholesterol < 1.0 mM.l-1 were alive 10 years after surgery. These data suggest that dyslipidaemia, especially the combination of high serum triglycerides and low HDL cholesterol, is an important factor influencing long-term clinical outcome after coronary bypass surgery.
