The Renal Arterial Resistance Index Predicts Worsening Renal Function in Chronic Heart Failure Patients.

Background/aim: The renal arterial resistance index (RRI) is a Doppler measure, which reflects abnormalities in the renal blood flow. The aim of this study was to verify the value of RRI as a predictor of worsening renal function (WRF) in a group of chronic heart failure (CHF) outpatients.

Methods: We enrolled 266 patients in stable clinical conditions and on conventional therapy.

Right Ventricular Longitudinal Strain Measures Independently Predict Chronic Heart Failure Mortality.

The assessment of right ventricular (RV) function still remains a challenge. Two-dimensional (2D) speckle tracking has recently been proposed to evaluate right ventricular function by analyzing myocardial deformation. The aim of this study was to evaluate the role of 2D systolic strain measures of RV in predicting mortality in patients with chronic heart failure (HF).

Independent role of left ventricular global longitudinal strain in predicting prognosis of chronic heart failure patients.

Aims: To evaluate the independent prognostic role of two-dimensional (2D) strain measures reflecting global longitudinal left ventricular (LV) systolic function in outpatients affected by chronic heart failure (CHF).

Methods And Results: Global longitudinal LV systolic strain (GLS) was assessed in 308 outpatients affected by CHF, by analyzing standard views with 2D speckle tracking technique. During a mean follow-up of 26 ± 13 months 37 patients died (29 due to cardiovascular causes), 10 patients underwent heart transplantation, and 75 patients experienced at least 1 episode of hospitalization due to acute decompensated heart failure (ADHF).
