Is diastolic dysfunction associated with thrombogenesis? A study of circulating markers of a prothrombotic state in patients with coronary artery disease

1995 
Abstract Clinical data on the contributory role of heart failure to thromboembolic risk does not differentiate between systolic and diastolic left ventricular dysfunction. We therefore conducted a population-controlled cross-sectional study to determine levels of plasma fibrinogen (associated with thromboembolism), fibrin D-dimer (a marker of fibrin turnover) and von Willebrand factor (a marker of endothelial dysfunction) in patients with ischaemic heart disease (a common cause of diastolic dysfunction) in whom left ventricular diastolic function was defined by echocardiography. We studied 106 patients: those with normal left ventricular function ( n = 42, Group 1); those with left ventricular dysfunction but without aneurysms ( n = 34, Group 2); and those with left ventricular aneurysm formation ( n = 30, Group 3). Each of these groups was subdivided into those with (a) and without (b) diastolic dysfunction. Diastolic dysfunction was present in over 60% of patients, irrespective of left ventricular systolic impairment. There were no significant differences in median levels of plasma fibrinogen, fibrin D-dimer or von Willebrand factor in each group of patients with ischaemic heart disease, whether or not left ventricular diastolic dysfunction was present (Mann-Whitney test; P = N.S.). Systolic (rather than diastolic) dysfunction was the main correlate of these (analysis of variance, general linear model — ANOVA-GLM — P
