Summary
Tricuspid annular plane systolic excursion (TAPSE) is linked to better exercise capacity in chronic heart failure patients. This finding helps estimate patient capacity and guide cardiac rehabilitation programs.
Area of Science:
- Cardiology
- Exercise Physiology
- Echocardiography
Background:
- The relationship between right ventricular function and exercise capacity in chronic heart failure (CHF) is not fully understood.
- While right ventricular reserve has been linked to exercise capacity, the specific role of tricuspid annular plane systolic excursion (TAPSE) remains unexplored.
- This study investigates the impact of TAPSE on exercise capacity in individuals undergoing cardiac rehabilitation.
Purpose of the Study:
- To determine the association between tricuspid annular plane systolic excursion (TAPSE) and exercise capacity in patients with chronic heart failure.
- To evaluate TAPSE as a predictor of exercise performance in cardiac rehabilitation candidates.
Main Methods:
- Retrospective analysis of data from 169 chronic heart failure patients.
- Collected data included cardiopulmonary exercise tests and transthoracic echocardiography before cardiac rehabilitation.
- Statistical analysis, including multivariate logistic regression, was used to assess the association between TAPSE and exercise capacity parameters.
Main Results:
- Higher TAPSE values were significantly associated with increased anaerobic threshold and peak oxygen consumption.
- TAPSE independently predicted both anaerobic threshold and peak oxygen consumption in multivariate analyses.
- The study included 169 CHF patients (70.3 ± 11.7 years, 74.6% men).
Conclusions:
- Right ventricular systolic function, as measured by TAPSE, is associated with exercise capacity in CHF patients.
- TAPSE can be a valuable tool for estimating exercise capacity and informing cardiac rehabilitation strategies.
- Further research is needed to explore the longitudinal implications and clinical utility of TAPSE in this population.

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

01:20Mitral Regurgitation I: Introduction
76
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...
