Dilated cardiomyopathy has been associated with left ventricular thrombosis, which leads to substantial morbidity and mortality as a site for peripheral emboli. There are some studies on patients with dilated cardiomyopathy showing altered haemostasis and platelet behaviour despite sinus rhythm. Mean platelet volume, which is the most accurate and simple estimate of platelet reactivity, may be associated with the development of left ventricular thrombosis. ⋯ Mean platelet volume is increased in patients with dilated cardiomyopathy and sinus rhythm having left ventricular thrombosis. This might be reflecting a causal relationship, which in turn requires further study to establish the role of antiplatelet agents both in prevention and in treatment.
