Stress Testing in Heart Failure with Preserved Ejection Fraction

Abstract

Exertional dyspnea is the most common symptom in patients with heart failure with preserved ejection fraction; however, it is not specific to this disease. Stress testing provides crucial information about the diagnosis and prognosis of heart failure with preserved ejection before it reaches the advanced stage. Among various stress tests, noninvasive supine bicycle diastolic stress echocardiography has provided the most evidence for diagnosing and predicting the prognosis of heart failure with preserved ejection fraction. In current practice guidelines, a noninvasive or invasive diastolic stress test is recommended when a diagnosis is unclear in resting echocardiography.
