Long‐term outcomes and reverse remodelling in recently diagnosed unexplained left ventricular systolic dysfunction

Aims In patients with recently diagnosed non‐ischaemic LV systolic dysfunction, left ventricular reverse remodelling (LVRR) and favourable prognosis has been documented in studies with short‐term follow‐up. The aim of our study was to assess the long‐term clinical course and stability of LVRR in these patients. Methods and results We prospectively studied 133 patients (37 women; 55 [interquartile range 46, 61] years) with recently diagnosed unexplained LV systolic dysfunction, with heart failure symptoms lasting
