Echocardiographic Diastolic Stress Testing: What Does It Add?

Diastolic stress echocardiography may help facilitate the attribution of exertional dyspnea to cardiac and non-cardiac disease. It represents a non-invasive hemodynamic test to assess the patients with unexplained dyspnea. It can improve the diagnosis of heart failure with preserved ejection fraction (HFpEF) or diastolic heart failure. A number of studies have validated exercise E/e′ as a measure of left ventricular (LV) filling pressure against...
