Purpose of Review
Diastolic dysfunction is an important, though often underappreciated, cause for exertional dyspnea. Echocardiography enables noninvasive evaluation of diastolic function and filling pressure, but images acquired at rest may be insensitive for detection of exertional abnormalities. This review focuses on stress echocardiography to assess diastolic function, including traditional and novel techniques, with emphasis on specific patient sub-groups in whom this testing may be valuable.
Recent Findings
Emerging data informs patient selection for diastolic stress testing. Further, increasing literature provides considerations for performance and interpretation of diastolic metrics relevant to patients with heart failure with preserved ejection fraction, hypertrophic cardiomyopathy, athletes, and those with microvascular coronary dysfunction. Methods, such as speckle-tracking and multi-modality imaging, provide additional and complementary information for non-invasive diastolic assessment.
Summary
This review serves as a guide to optimally utilize existing and novel techniques of stress echocardiography for diastolic assessment across a broad range of patients.
