Background: Rate Pressure Product (RPP) is an independent index of cardiac work. We aimed to assess the significance of the RPP in patients with chronic Heart Failure (HF) and its relation to their Echocardiographic findings.Methods: This prospective study included 358 patients with chronic HF 201 (56.1%) HF preserved Ejection Fraction (HFpEF) and 157 (43.9%) HF reduced EF (HFrEF)], as 3 groups; average resting RPP 7-10 (n=229), high resting RPP>10 (n=88) and low resting RPP <7 (n=41). NYHA class, Heart Rate (HR), blood pressure, RPP were estimated, S3 and rales were evaluated. Echocardiographic parameters; Left Ventricular End Diastolic (LVEDd), LV End Systolic dimensions (LVESd), LV-EF and LV-Stroke Volume Index (SVI) were obtained.Results: Patients with low RRP had significantly higher prevalence of S3, rales, limiting dyspnea and lower EF. Patients with high RPP .. View More»
