AIMS: Improvement in left ventricular (LV) systolic reserve, including exertional increase in global longitudinal strain (GLS), may contribute to the clinical benefit from therapeutic interventions in heart failure with preserved ejection fraction (HFpEF). However, GLS is an afterload-dependent parameter, and its measurements may not adequately reflect myocardial contractility recruitment with exercise. The estimation of myocardial work (MW) allows correction of GLS for changing afterload. We sought to investigate the associations of GLS and MW parameters with the response of exercise capacity to spironolactone in HFpEF. METHODS AND RESULTS: We analysed 114 patients (67 ± 8 years) participat..View full abstract
