Abstract

The aim of the present study was to investigate whether the von Willebrand factor levels, as a possible indicator of endothelial dysfunction, is increased in hypertrophic cardiomyopathy, and also whether it is related to the clinical status of hypertrophic cardiomyopathy. The study group comprised 29 patients with hypertrophic cardiomyopathy and 29 healthy age- and gender-matched control subjects. There was no significant difference in von Willebrand factor levels between study group (77.0 +/- 23.1%) and control group (88.5 +/- 34.2%). There was no statistically significant difference between control group (88.5 +/- 34.2%) and functional class I/II group (82.0 +/- 24.3%), between control group and functional class III group (67.6 +/- 18.3%) and between functional class I/II group and functional class III group with respect to the von Willebrand factor levels. The results suggest that von Willebrand factor levels, as a possible indicator of endothelial dysfunction, are not increased in patients with hypertrophic cardiomyopathy and von Willebrand factor levels are not related to functional class in these patients.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
