Diastolic Mechanisms for Systolic Dysfunction During Exercise
many patients with essential hypertension. To assess the determinants of the abnormal ejection fraction response to exercise, we performed radionuclide angiography at rest and during exercise in 41 hypertensive patients without coronary artery disease. In 22 patients (group 1), the ejection fraction increased more than 5% during exercise; in the other 19 patients (group 2), the ejection fractio...
متن کاملVorticity is a marker of right ventricular diastolic dysfunction.
Right ventricular diastolic dysfunction (RVDD) is an important prognostic indicator in pulmonary arterial hypertension (PAH). RV vortex rings have been observed in healthy subjects, but their significance in RVDD is unknown. Vorticity, the local spinning motion of an element of fluid, may be a sensitive measure of RV vortex dynamics. Using four-dimensional (4D) flow cardiac magnetic resonance i...
متن کامل4D Flow Assessment of Vorticity in Right Ventricular Diastolic Dysfunction
Diastolic dysfunction, a leading cause of heart failure in the US, is a complex pathology which manifests morphological and hemodynamic changes in the heart and circulatory system. Recent advances in time-resolved phase-contrast cardiac magnetic resonance imaging (4D Flow) have allowed for characterization of blood flow in the right ventricle (RV) and right atrium (RA), including calculation of...

متن کاملLeft and right ventricular diastolic dysfunction and diastolic heart failure: does one lead to the other?
Background and Objective Diastolic dysfunction of the left ventricle is a mechanical abnormality diagnosed primarily by echocardiogram, and can be distinguished into three separate degrees based on the severity of reduction in passive compliance and active myocardial relaxation. Methods A literature search was performed for basic science studies, clinical studies and major practice guidelines o...
