Myocardial constructive work is impaired in hypertrophic cardiomyopathy and predicts left ventricular fibrosis

Background The estimation of myocardial work by pressure strain loops ( PSL s) is a totally new non‐invasive approach to assess myocardial performance, and its role in patients with hypertrophic cardiomyopathy is unknown. The aims of the present study are therefore: (a) to compare myocardial work in patients with non‐obstructive hypertrophic cardiomyopathy ( HCM ) and in a subset of age‐matched healthy controls and (b) to assess the correlation...
