Right coronary artery diastolic perfusion pressure on outcome of patients with left heart failure and pulmonary hypertension.

Aims: Right ventricle adaptation to prolonged exposure against pulmonary hypertension (PH) includes structural and functional abnormalities, translated into modifications of blood flow pattern through the right coronary artery. Given these changes, we investigate the relationship between right coronary artery diastolic perfusion pressure (RCDPP) and clinical outcome, in patients with PH secondary to left-sided heart failure (HF).

Methods And Results: We studied 108 HF patients who underwent right heart catheterization.
