Acute myocardial infarction may result from rupture or fissuring of atherosclerotic plaque in a coronary artery. Sometimes a different pathogenesis occurs like microembolization following lysis from ulcerated plaque or during pharmacological or interventional procedures. We describe a patient with anterior myocardial infarction treated with alteplase + abciximab (TIMI 14). At the end of thrombolytic therapy administration, we observed a marked reduction of anterior ST elevation associated with a simultaneous occurrence of ST elevation in the inferior leads, later followed by inferior Q waves. The coronary angiogram demonstrated an isolated 60% stenosis on the left anterior descending artery. This case raises the question on whether the very effective and aggressive thrombolytic treatment was paradoxically responsible for microembolization resulting in myocardial infarction extension.

Repeated administration of t-PA and abciximab in a patient with anterior myocardial infarction - a case report. A case of a 40-year-old male with acute anterior myocardial infarction (MI) is presented. Due to the angiographic equipment failure, the patient did not undergo primary angioplasty and received heparin and 100 mg of t-PA. This treatment was associated with clinical and ECG signs of reperfusion, however, 30 minutes after completion of t-PA infusion, the patient developed clinical and ECG signs of re-occlusion. The decision was made to transfer the patient to a catheterisation laboratory for further invasive treatment, however, it was located 200 km from our centre. Because of that, the patient received another dose of 50 mg of t-PA and abciximab before transportation. Further course was uncomplicated and the patient underwent successful stent implantation in the other centre.

We report a case of a 60-year-old man with obstructive aortic prosthetic valve thrombosis (APVT). He was treated with low-dose (25 mg) slow infusion (6 hours) of intravenous tissue plasminogen activator (t-PA), and he suffered acute anterior myocardial infarction (MI) at the fourth hour of t-PA infusion. Infusion was kept on, and coronary reperfusion and successful lysis of APVT were achieved. Intravenous unfractionated heparin (UFH) was then started, however, on the third day following heparin treatment, heparin-induced thrombocytopenia (HIT) was recognized by a drop in the platelet count and rethrombosis of the prosthetic valve. Although no nonheparin anticoagulant was available, intravenous continuous infusion of streptokinase (SKZ) 250,000 U per day was administered for 5 days followed by transition to warfarin therapy. Successful lysis of the APVT was again achieved with this regimen and the patient was discharged after uneventful recovery. The patient remained well at 6 months and 1 year follow-up.

Embolic complications of intravenous thrombolysis for acute ischemic stroke are increasingly recognized, and to date several cases of myocardial infarction soon after the administration of alteplase have been reported. We describe a case of early anterior myocardial infarction during intravenous thrombolysis for stroke and review the current literature.
