What is Right Ventricular Myocardial Systolic and Diastolic Dysfunction in Heart Failure with Normal Left Ventricular Ejection Fraction about?
## Objective: We hypothesized that in patients with heart failure with normal left ventricular (lv) ejection fraction (hfnef), the same fibrotic processes that affect the subendocardial layer of the lv could also alter the subendocardial fibers of the right ventricle (rv). consequently, these alterations and to a lesser extent chronically elevated pulmonary arterial pressures would lead to both systolic and diastolic subendocardial dysfunction of the rv (i.e., impaired rv longitudinal systolic and diastolic function) in patients with hfnef. ## Methods: Patients with hfnef and a control group consisting of asymptomatic patients with lv diastolic dysfunction (asymptomatic lvdd) matched by age, gender, and lv ejection fraction were studied by two-dimensional speckle-tracking echocardiography. ## Results: A total of 565 patients were included (201 with hfnef and 364 with asymptomatic lvdd). rv longitudinal diastolic (rv global longitudinal early-diastolic strain rate [rv-sre]) and systolic (rv global longitudinal systolic strain [rv-strain]) function were significantly more impaired in patients with hfnef than in patients with asymptomatic lvdd (hfnef: rv-strain -14.41% ± 3.80% and rv-
