We describe an autopsy case of severe intracranial hemorrhage which occurred during the infusion of tissue plasminogen activator (t-PA) for acute myocardial infarction. A 75-year-old man was admitted with substernal chest pain of 3-h duration and electrocardiographic changes consistent with an acute inferior myocardial infarction. Physical examination was unremarkable, except for an initial blood pressure reading of 160/96 mmHg. The patient received 3,000 IU intravenous heparin followed by a 2.4 x 10(6) IU bolus dose of tissue plasminogen activator (t-PA) (Alteplase). This was followed by a drip infusion of 21.6 x 10(6) IU of t-PA over 1 h (total dose 41 mg). Thirty minutes after the infusion of t-PA was initiated, the patient suddenly lost consciousness and began to have violent convulsions, followed by cardiac arrest. Autopsy revealed massive hemorrhage in the bilateral cerebrum and brain stem. To our knowledge, this is the first case of sudden death during t-PA infusion therapy.

Although it is well known that diabetics have high mortality rates due to ischemic heart disease (IHD), controversies still exist about the severity of coronary artery disease in diabetics compared to nondiabetics. We compared coronary arteriographies of 50 diabetics with IHD to those of 50 nondiabetics with IHD. In regard to coronary risk factors, incidence of obesity was significantly higher in diabetics. Incidence of hypertension, hypercholesteremia, hyperuricemia was higher, although not significant, in diabetics. Incidence of smoking was significantly higher in nondiabetics. The diabetic group showed a significantly higher incidence of patients with more than two or three diseased vessels, and a significantly higher number of diseased coronaries with more than 50% stenosis per patient compared to nondiabetics (5.6 +/- 3.7 vs 3.7 +/- 3.2). The distribution of diseased coronaries with more than 75% stenosis showed no difference between diabetics and nondiabetics. The incidence of coronary spasm was significantly lower in diabetics (12% vs 28%). The high incidence of multiple vessel disease in diabetics was thought to be due to other complicated coronary risk factors, especially hypertension and hypercholesteremia.
