Abstract
A 69-year-old man with severe haemophilia A sustained an acute myocardial infarction (MI) after self-administration of 3000 units factor VIII over 10 min. On admission he had no signs of heart failure. The ECG showed an acute posterior wall MI. Creatinekinase rose to a maximum of 321 U/l with a significant MB proportion. The echocardiogram demonstrated hypokinesia of the posterior wall. After initial thrombolysis treatment with a total of 100 mg rtPA according to an accelerated scheme coronary angiography, performed because the symptoms persisted, revealed two-vessel disease. A subtotal stenosis of the right coronary artery was balloon-dilated with good primary results. Regular factor VIII substitution was temporarily administered with the aim of initially achieving high normal levels of factor VIII activity. Factor VIII substitution in haemophilia A may promote thrombotic complications. Thrombolytic treatment and balloon angioplasty of acute MI can be successfully performed even in patients with severe haemophilia A.
