Respiratory Muscle Strength and Quality of Life in Patients With Heart Failure and Their Main Correlated Factors: A Cross-sectional Study.

Background: Heart failure may cause peripheral and respiratory muscle alterations, dyspnea, fatigue, and exercise intolerance, worsening the quality of life of patients.

Objectives: The aims of this study were to analyze respiratory muscle strength and quality of life of patients with heart failure and correlate them with clinical variables and functional classification.

Methods: This cross-sectional study involved patients with heart failure.

Analysis of respiratory muscle strength and its relationship with functional capacity between different field tests in patients with heart failure.

Objective: To analyze respiratory muscle strength of patients with heart failure (HF) and correlate with functional capacity.

Methods: This cross-sectional study involved patients with compensated HF of both sexes, aged above 18 years. Respiratory muscle strength was assessed by measuring maximum inspiratory (MIP) and expiratory pressures (MEP) using a manovacuometer.

Effect of short-term positive airway pressure on blood pressure in controlled hypertensive patients with obstructive sleep apnoea syndrome: a prospective cohort study.

Background: Obstructive sleep apnoea syndrome (OSAS) is associated with cardiovascular disease, especially in patients with high blood pressure. Continuous positive airway pressure (CPAP) seems to contribute to blood pressure control in patients with OSAS, mainly those with uncontrolled hypertension. However, the effect of CPAP on controlled hypertensive patients with OSAS is not known.
