In 1968 and 1972--1973 investigations in Copenhagen city were performed in order to acquire data concerning the occurrence of acute ischaemic heart disease (AIHD), including sudden coronary death (SCD). The incidence of AIHD was 0.4% with a total mortality of 56%. Of all patients with AIHD 40--45% terminated in SCD, being responsible for about a quarter of all deaths in Copenhagen city at that time. Patients suffering CSD had more seldom a previous history of ischaemic heart disease (IHD) than patients with AIHD not complicated by cardiac arrest/SCD. Patients with a previous history of IHD and/or prodromal symptoms had a longer decision time before calling a doctor or an ambulance than patients without such symptoms, especially the elderly. The decision time was neither affected by the day of the week nor the month of the year with regard to the occurrence of cardiac symptoms. On the other hand, the mean decision time was significantly longer if symptoms began between 12 midnight and 8 a.m. compared with the other times of the day. The study showed finally that younger people are more liable to die from SCD outside hospital than the elderly.

Dyslipidemia and coronary artery disease. Prevalence and treatment in patients referred for coronary arteriography.

UNLABELLED: A reduction in serum total cholesterol (T-C) levels has been shown to reduce mortality in patients with coronary artery disease and to decrease the need for revascularization. To examine the prevalence and treatment of lipid disorders in patients referred for their first coronary angiogram, medical history and fasting blood samples were collected in 108 consecutive patients. Ninety-one patients (84.3%) fulfilled the criteria for dyslipidemia. Hypercholesterolemia had previously been demonstrated in 53 patients (49.1%), and 34 (64.2%) of these patients still had T-C > 6.0 mmol/l at the time of admission. Among 55 patients who were unaware of any lipid disorders at admission, 28 (50.9%) had T-C > 6.0 mmol/l. CONCLUSION: The majority of patients referred for their first coronary angiogram and possible revascularization suffered from dyslipidemia. Many patients with previously recognized dyslipidemia were insufficiently treated.

Long-term survival after myocardial infarction as related to early complications.

The material consists of 404 hospitalized patients with their first AMI. After an observation time of 1 and 5 yr, respectively, the mortality was 27% and 45%, against an expected mortality of 3% and 17% in a corresponding normal population. The annual mortality rate was 5.5% from 1 to 3 yr after the acute infarction, against an expected 3.5%. 3-5 yr after occurrence of the infarction, both the observed and expected annual mortality rates were 3.5%. In patients alive 1 mth after the acute attack, congestive heart failure (CHF) or left bundle branch block (LBBB) or secondary ventricular fibrillation (VF) during the acute phase gave a lower long-term survival, as compared to patients without CHF, intraventricular block or VF, respectively. Left anterior hemiblock, complete atrioventricular block following inferior infarction, or primary VF had no influence on the long-term prognosis.
