Right ventricular failure is common in acute left heart failure and is strongly associated with the severity of left ventricular diastolic dysfunction and pulmonary hypertension.
May support RV assessment in acute left HF with advanced diastolic dysfunction; hypothesis-generating for prognostic and therapeutic implications.
Pulmonary hypertension, which may lead to right ventricular (RV) failure, increases with left ventricular (LV) diastolic dysfunction severity. The prevalence and determinants of RV failure were analyzed in 120 patients admitted with acute left heart (LH) failure. Patients were divided into RV failure (n=50) and non-RV failure (n=70) groups. The prevalence of RV failure was found to be 42%. In both groups, two thirds of the patients had isolated LV diastolic dysfunction and the rest had combined LV systolic and diastolic dysfunction. Patients in the RV failure group were characterized by higher LV diastolic grade (2.2 ± 0.6 vs 1.84 ± 0.7; P=.0070), pulmonary artery systolic pressure (PASP; 57.8 ± 15.3 vs 50.14 ± 12.1 mm Hg; P=.0028), right atrial enlargement (92% vs 25.7%; P=.000001), and more-than-moderate tricuspid regurgitation (58% vs 27.1%; P=.0006). RV failure is a frequent finding in patients with advanced LH failure. It is strongly associated with the severity of LV diastolic dysfunction and the severity of PASP.
