The Northern Halland Project: On the Need for Support of Patients with Myocardial Infarction in Northern Halland, Sweden

Introduction In the developed countries cardiovascular diseases are one of the main reasons for mortality and chronical, extended suffering (Werko , 1971, Pooling Project Research Group, 1978, World Health Organisation, 1982). In Sweden more than 40 000 patients are treated in hospitals for myocardial infarction every year, and 20 000 of them are under the age of 75. Today the number of infarctions in ages under 45 years is increasing. Myocardial infarction is much more common amongst males but mortality is more frequent in younger females (Bengtsson, 1973, Leren et aI, 1975, Statistiska Centralbyran, 1977, Holme et aI, 1977). The preventive efforts of chronical cardiovascular diseases have increased during the last decade in modern health care (Elmfeldt et aI, 1976, Hamburg, 1979, McAlister et aI, 1982). While the cases of myocardial infarction are increeasing, predisposing factors seem to be more important. One of these factors for a second infarction is the psycho-social stress and the crisis connected with the changed life situation after a myocardial infarction (Dominian and Dobson, 1969, Cassem and Hackett, 1971, Theorell, 1973, Orth-Gomer, 1979).
