title: Is haemorrhagic myocardial infarction more common with streptokinase?
abstract: Autopsy reports and clinical data of 226 consecutive myocardial infarction deaths in whom postmortem studies could be carried out during the period 1980 to 1996 were analyzed retrospectively for the presence of haemorrhagic myocardial infarction (HMI). Of 53 autopsies done from 1980 to 1986 [prior to use of streptokinase (SK) therapy in our institution] none of the specimens showed haemorrhagic infarction. Of 173 autopsies done from 1987 to 1996 (intravenous SK therapy was utilised in this period), 20 specimens showed haemorrhagic infarctions. Sixteen of these 20 patients had received SK, while 66 of the remaining 153 non-haemorrhagic myocardial infarction patients received SK (statistically significant association of SK with HMI, p < 0.005). Acute mechanical complications [ventricular septal rupture (n = 10), papillary muscle rupture (n = 2), cardiac free wall rupture (n = 7)] were seen in 19 cases. Of these, 16 were HMIs and 14 of these patients had received streptokinase. These observations suggest a strong association of HMI with SK therapy and with acute mechanical complications.
