The impact of thrombolytic therapy on hospital mortality from acute myocardial infarction in the Chinese in Hong Kong.
Thrombolytic therapy using recombinant-tissue plasminogen activator, urokinase and streptokinase for acute myocardial infarction was instituted in the coronary care unit of the Prince of Wales Hospital in Hong Kong in 1988. To evaluate its impact on hospital mortality of acute myocardial infarction, the database of 465 patients (mean age 65.2 +/- 12.6 yr) admitted into the coronary care unit in the period between 1985-1990 was collected prospectively and their clinical course reviewed. Three hundred and thirty-five patients were males and 130 were females. Patients in the prethrombolytic era (1985-87) and the thrombolytic era (1988-90) were matched for age, proportion of females and clinical severity. One hundred and two patients (39.5%) received thrombolytic therapy. The overall hospital mortality (18.6%) in the thrombolytic era and that for each sex (18.2% in the males; 19.5% in the females) were significantly lower than those of prethrombolytic era (27.1%, 23.4% and 37.7%, respectively). No death was due to bleeding complication. The benefit of thrombolytic therapies in the Chinese was confirmed. More effort is needed to popularize this concept in the Chinese communities, to shorten the prehospital delay of patients and to extend its utilisation to the elderly patients.
