Geographical variation and time trends in the attack rate of coronary heart disease in five Swedish cities.

Based upon community myocardial infarction (MI) records in five Swedish cities, geographical variation and time trends in the attack rate of fatal and non-fatal MI have been evaluated. During the study period 1975-1982, a total of 7699 events were registered among men and 1823 events among women. The mean annual mortality was highest in the north, and a declining gradient in mortality was observed from the northern to the southern part of the country.

Identification of cases of myocardial infarction: hospital discharge data and mortality data compared to myocardial infarction community registers.

Identification of incident myocardial infarction (MI) cases in a defined population using hospital discharge data and mortality data in combination has been suggested. This method of case identification was compared to that of use of MI community registers set up in accordance with principles adopted in a World Health Organization collaborative programme. The comparison comprised data for four Swedish cities over a number of years.

Clinical efficacy of hydralazine in chronic heart failure: one-year double-blind placebo-controlled study.

In a placebo-controlled trial 62 patients with chronic congestive heart failure (CHF) (New York Heart Association class III) had hydralazine (149 +/- 11 mg daily) or placebo added to conventional therapy. During 12 months' follow-up 27 patients dropped out, 15 of 32 in the hydralazine group and 12 of 30 among the control subjects. The 1-year mortality rate was 28% in the hydralazine group compared to 27% in the control group.

A controlled study of early discharge after uncomplicated myocardial infarction.

Out of 383 myocardial infarction (MI) patients aged below 70 years, 252 (66%) were judged after the third day in hospital to have had uncomplicated infarctions. These patients were allocated at random to two groups, one of which was given treatment for 8 days and the other for 15 days. No significant differences in mortality, morbidity or incapacity for work could be detected during the three-month period of follow-up.

The Landry-Guillain-Barré syndrome and pregnancy.

The Landry-Guillain-Barré syndrome is considered rare in connection with pregnancy. In mild cases the course of the pregnancy is unaffected. In severe cases, with respiratory depression and bulbar symptoms, especially during late pregnancy, the syndrome entails an increased risk to both mother and foetus.

Long-term treatment with beta-blockers after myocardial infarction.

162 patients discharged from hospital after mycardial infarction were randomly allocated to two groups, one received alprenolol 400 mg daily and the other served as the control. The period of follow-up was two years and all other treatment given was standardized. The two groups did not differ with respect to risk factors for myocardial infarction, the course of the acute infarct or treatment during follow-up.

Extreme digitalis intoxication.

A case of massive digoxin intoxication is described. The concentration of digoxin in plasma, 15.5 ng/ml, is one of the highest observed in an individual not having heart diease who survived the intoxication.
