Abstract
BACKGROUND: 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.
METHODS AND RESULTS: 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.
CONCLUSIONS: 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.
