Right ventricular reserve in cardiopulmonary disease: a simultaneous hemodynamic and three-dimensional echocardiographic study.

Background: RV reserve has been linked to exercise capacity and prognosis in cardiopulmonary diseases. However, evidence in this setting is limited, due to the complex shape and load dependency of the RV. We sought to study right ventricular (RV) adaptation to exercise by simultaneous three-dimensional echocardiography (3DE) and right heart catheterization (RHC).

Effect of a new resistance training method on the metaboreflex in cardiac rehabilitation patients: a randomized controlled trial.

Patients with cardiac disease exhibit exaggerated sympathoexcitation, pressor, and ventilatory responses to muscle metaboreflex activation (MMA). However, the effects of cardiac rehabilitation (CR) and especially resistance training (RT) modalities on MMA are not well known. This study investigated how CR impacts MMA in such patients, specifically examining the effects of two different resistance training (RT) protocols following 12 weeks of CR.

Effects of High-Intensity Interval Training Using the 3/7 Resistance Training Method on Metabolic Stress in People with Heart Failure and Coronary Artery Disease: A Randomized Cross-Over Study.

The 3/7 resistance training (RT) method involves performing sets with increasing numbers of repetitions, and shorter rest periods than the 3x9 method. Therefore, it could induce more metabolic stress in people with heart failure with reduced ejection fraction (HFrEF) or coronary artery disease (CAD). This randomized cross-over study tested this hypothesis.

How Does the Method Used to Measure the VE/VCO Slope Affect Its Value? A Cross-Sectional and Retrospective Cohort Study.

Cardiopulmonary exercise testing (CPET) was limited to peak oxygen consumption analysis (VOpeak), and now the ventilation/carbon dioxide production (VE/VCO) slope is recognized as having independent prognostic value. Unlike VOpeak, the VE/VCO slope does not require maximal effort, making it more feasible. There is no consensus on how to measure the VE/VCO slope; therefore, we assessed whether different methods affect its value.

Hemodynamic Tolerance of New Resistance Training Methods in Patients With Heart Failure and Coronary Artery Disease: A RANDOMIZED CROSSOVER STUDY.

Purpose: The purpose of this study was to determine and compare the effectiveness of three different resistance training (RT) methods for cardiac rehabilitation.

Methods: Individuals with heart failure with reduced ejection fraction (HFrEF, n = 23) or coronary artery disease (CAD, n = 22) and healthy controls (CTRL, n = 29) participated in this randomized crossover trial of RT exercises at 70% of the one-maximal repetition on a leg extension machine. Peak heart rate (HR) and blood pressure (BP) were measured noninvasively.
