The relationship between causal attribution and rehabilitation in patients after their first myocardial infarction. A cross cultural study.

Full rehabilitation of a patient following myocardial infarction (MI) involves resumption of work and the restoration of quality of life. Two groups of patients (87 Israeli and 98 Swedish) were admitted to the CCU and followed up after their first MI. To evaluate the patients' own perception of events ('causal attribution theory'), sequential interviews were scheduled. Physical risk factors correlated poorly with rehabilitation outcome at 6 months. However, two patient clusters were pinpointed according to the patients' subjective explanation of the factors contributing to their MI. These 'causal attribution scores' had a predictive value, independent of culture, age, education, disease severity and depression. It is therefore concluded that evaluation of patient perception may assist in planning intervention for high risk psychologically debilitated patients, and thus favourably enhance their rehabilitation outcome.

[Reocclusion following thrombolytic treatment in acute myocardial infarct].

Currently there are five thrombolytic substances undergoing evaluation: streptokinase, tissue plasminogen activator, acylated plasminogen streptokinase activator complex, urokinase and single chain urokinase plasminogen activator. Equal results for mortality reduction (25 per cent) and reocclusion (6-24 per cent) has been reported in the literature for the five substances. Reocclusion can be divided into an early (greater than 24 hours) and a late phase. The early phase is most likely due to an imbalance between thrombolysis and the formation of a thrombus. During late reocclusion there is formation of a thrombus on the underlying coronary plaque or residual thrombotic mass, following thrombolytic therapy. The residual stenosis following thrombolysis seems to be the most important prognostic factor for reocclusion. A residual stenosis of over 75 per cent is unfavourable. Early reocclusion is prevented through simultaneous antithrombotic and thrombolytic therapy. Patients with a residual stenosis of over 75 per cent should be considered for some sort of active intervention to prevent late reocclusion.

Prediction of sudden death in patients discharged after acute myocardial infarction.

A follow-up was made of 475 patients discharged after an acute myocardial infarction. Sudden death, i.e. death within 2 hours after the onset of the final attack, was more common in patients below 60 years on admission than in the older age groups. Patients succumbing suddenly often had a history of an earlier myocardial infarction. They also had a higher incidence of inferior infarcts and more frequently showed ventricular tachycardia during the early hospital period than those dying more than 24 hours after the onset of the final episode. When comparisons were made with all patients dying after more than 2 hours' duration of the terminal attack no significant differences were noted for these or other parameters. Prediction of sudden death in immediate survivors of acute myocardial infarction thus seems elusive. Further studies of the relations between the incidence of ventricular ectopic activity during the early and late hospital phase of acute myocardial infarction and sudden death after discharge from hospital are implicated.
