“…Studies of 151–200 patients found LV hypertrophy or enlargement (77.5%), RV enlargement (59%), tricuspid regurgitation (54.5%), LVEF < 50% (50%), pulmonary hypertension (45.5%), and pericardial effusion (12.5%) but did not find any association between TTE findings and mortality [ 47 ]. On the other hand, a study with the same number of subjects found an association between abnormal TAPSE, hazard ratio (HR) (HR 4.3, CI 1.68–11.60), and stroke work index (SWI) (HR 2.12, CI 1.00–5.23) [ 48 ].…”
