| Popis: | Background: Left ventricular global longitudinal strain (GLS) analysis using two-dimensional (2D) speckle-tracking echocardiography (STE) is a method for detecting subclinical systolic dysfunction. We hypothesized that exercise capacity (EC) is more closely related to systolic than diastolic dysfunction, especially to GLS in patients with heart failure and preserved ejection fraction (HFpEF). Methods: We assessed LV systolic and diastolic function in 172 patients with HFpEF using 2D echocardiography and STE. EC measured in units of metabolic equivalents (METs) was assessed using Bruce protocol treadmill stress testing. We defined reduced EC as |
