Spontaneous echo contrast imaging in infective endocarditis: a predictor of complications?

1992

Infective endocarditis is associated with significant morbidity and mortality. Valvular destruction and congestive heart failure are more common in patients with echocardiographically detectable vegetations. In addition, spontaneous platelet aggregation is increased when vegetations are present on cardiac valves. The aim of the study was to assess the prognostic value of spontaneous echo contrast (SEC) imaging, as SEC is supposed to reflect red blood cell aggregates stimulated by platelet activity. We studied 293 patients with clinical signs of infective endocarditis. Vegetations, attached to the aortic or mitral valve, were found in 130 patients (44.4%) who were followed for a mean period …

Platelet Function Changes in Acute Myocardial Infarction

1984

Whether the thrombotic component of myocardial infarction is primary or secondary in a given patient, platelet function alterations can influence many mechanisms — operating at the microenvi-ronmental level — from which it depends if the thrombotic lesion grows or sends platelet emboli to the smaller myocardial vessels.

Spontaneous platelet aggregation as a predictive risk factor for vascular occlusions in healthy volunteers? Results of the HAPARG Study

1999

The HAPARG Study (haemostatic parameters as risk factors in healthy volunteers) was performed in a subset of volunteers taking part in the MARISK Study (Mainzer Risikoindikatoren Studie fur die koronare Herzkrankheit) sponsored by the German Ministry of Research and started in 1984. A previous study (Yamanishi et al., Thromb Haemostas 1985;54:539-543) had shown that spontaneously enhanced platelet aggregation as measured with the PAT-III-test and higher fibrinogen concentrations are significant risk factors for new vascular occlusions in diabetic patients. It was the aim of the HAPARG Study to establish whether spontaneous platelet aggregation and other hemostatic variables are independent …
