ANTICARDIOLIPIN ANTIBODIES AND CORONARY HEART-DISEASE

Arterial or venous thrombotic events have been described as complications in patients with positive anticardiolipin antibodies (aCL), affecting various organs including the heart. In order to see whether aCL could be, among others, a predisposing factor for coronary artery occlusions and whether it could serve as a prognostic marker for coronary heart disease, 232 patients enrolled in the European Concerted Action on Thrombosis Angina Pectoris Study were studied. aCL and various other haemostatic parameters were determined at time of admittance in order to see whether a relationship existed between haemostasis at baseline and extent or prognosis of the cardiovascular disease. A follow-up at 12 and 24 months after angiography included information about relapsing coronary or other thrombotic events, treatment and outcome of the disease. aCL were not found to be a marker of either progressive cardiovascular disease or recurrent thrombotic events. No correlation was found, either in aCL positive or in aCL negative patients, between high levels of haemostasis activation markers, such as β-thromboglobulin, platelet factor 4 or -fibrinopeptide A and recurrent cardiovascular disease. © 1992 The European Society of Cardiology.
