Cardiac power (CP) output in patients with heart failure has been studied, while its importance in hypertrophic cardiomyopathy (HCM) patients is yet unclear.
99 HCM patients and 65 gender- and age-matched controls with cardiac MR were included in the study. HCM patients showed significantly higher CP (p=0.031) but lowered NCP (p<0.001) than the controls. The correlation analysis of NCP and functional parameters revealed that NCP was inversely correlated with LV mass (R=-0.395, p<0.001) in HCM patients.
NCP decreased significantly in HCM patients and may continue to deteriorate with increasing LV mass.
