Short physical performance battery in the pre and postoperative myocardial revascularization surgery in older adults: Reliability, hemodynamic responses, subjective perceived exertion, and adverse events.

Introduction: The Short Physical Performance Battery (SPPB) may be feasible for evaluating older adults undergoing myocardial revascularization surgery (MRS). However, it is necessary to verify its measurement properties and safety to use it for clinical practice.

Objective: To investigate the reliability, hemodynamic responses, subjective perceived exertion (SPE), and adverse events during and after SPPB in older adults undergoing MRS.

Left lateral intercostal region versus subxiphoid position for pleural drain during elective coronary artery bypass graft surgery: randomized clinical trial.

Background: The pleural drain insertion site after coronary artery bypass graft (CABG) surgery may alter lung function, especially respiratory muscle strength. The main objective of this study was to compare the effectiveness and safety of use of the left lateral intercostal region versus the subxiphoid position for pleural drainage during elective CABG surgery using extracorporeal circulation (ECC).

Design And Setting: Randomized trial conducted in a tertiary-level hospital in Porto Alegre, Brazil.

Effects of High-Intensity Inspiratory Muscle Training Associated with Aerobic Exercise in Patients Undergoing CABG: Randomized Clinical Trial.

Objective: Evaluate the interaction between high-intensity inspiratory muscle training (IMT) and aerobic exercise on physical capacity, respiratory muscle strength, peripheral muscle strength, and quality of life of patients who underwent coronary artery bypass grafting (CABG).

Methods: Twenty-four patients underwent CABG were randomized into two groups. During 36 sessions, one group received IMT associated with aerobic exercise and the other group received only aerobic exercise.

Effects of Transcutaneous Electrical Nerve Stimulation in Autonomic Nervous System of Hypertensive Patients: A Randomized Controlled Trial.

Background: Patients with hypertension have altered autonomic nervous system function, which are increased sympathetic activity. Transcutaneous Electrical Nerve Stimulation (TENS) is a useful modality for pain control and has also been shown to be effective in the reduction of sympathetic activity in healthy subjects and individuals with cardiovascular diseases.

Objective: The aim of this study was to verify the effects of transcutaneous electrical nerve stimulation by the evaluation of heart rate variability (HRV) in patients with essential hypertension.

Acute Effects of Low-Level Laser Therapy on Patients' Functional Capacity in the Postoperative Period of Coronary Artery Bypass Graft Surgery: A Randomized, Crossover, Placebo-Controlled Trial.

Objective: The aim of this study was to evaluate the acute effects of low-level laser therapy (LLLT) on the functional capacity to exercise tested by incremental shuttle walking test (ISWT) after coronary artery bypass graft (CABG) surgery.

Methods: Fifteen male patients (60 ± 9 years) were crossed over during the experiment, to compare the outcomes after active LLLT and placebo LLLT treatments. LLLT (850 nm, 200 mW, 30 J to each point, resulting in a total of 240 J per quadriceps muscle), using a multidiode cluster (five spots; 6 J/spot) in eight points per leg was performed 3 min before the ISWT.

Respiratory training improved ventilatory function and respiratory muscle strength in patients with multiple sclerosis and lateral amyotrophic sclerosis: systematic review and meta-analysis.

Background: Among neurodegenerative diseases, multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) have a high rate of respiratory disability.

Objectives: To analyze the effects of respiratory muscle training (RMT) on ventilatory function, muscle strength and functional capacity in patients with MS or ALS.

Data Sources: A systematic review and meta-analysis of randomized controlled trials (RCTs) was performed.

Exercise capacity in children and adolescents with corrected congenital heart disease.

Congenital heart disease promotes hemodynamic changes that can contribute to reduce exercise capacity. The aim of the study was to evaluate the exercise capacity of children and adolescents with cyanotic congenital heart disease and to assess respiratory muscle strength, plasma levels of B-type natriuretic peptide and ventricular ejection fraction, as well the associations between these variables. Cross-sectional study that evaluated 48 patients between 6 and 18 years-old that underwent a six-minute walk test (6MWT), respiratory muscle strength, dosage of B-type natriuretic peptide and echocardiography.

Continuous positive airway pressure reduces blood pressure in patients with obstructive sleep apnea; a systematic review and meta-analysis with 1000 patients.

Background: Obstructive sleep apnea (OSA) may lead to the development of hypertension and therapy with continuous positive airway pressure (CPAP) can promote reduction in blood pressure.

Objective: The objective of this study is to review systematically the effects of CPAP on blood pressure in patients with OSA.

Methods: The search was conducted in the following databases, from their beginning until February 2013: MEDLINE, Embase, Cochrane CENTRAL, Lilacs and PEDro.

Expiratory and expiratory plus inspiratory muscle training improves respiratory muscle strength in subjects with COPD: systematic review.

Background: Inspiratory muscle training (IMT) produces beneficial effects in COPD subjects, but the effects of expiratory muscle training (EMT) and EMT plus IMT in ventilatory training are still unclear. The aim of this study was to systematically review the effects of EMT and EMT plus IMT compared to control groups of COPD subjects.

Methods: This study is a systematic review and meta-analysis.

Transcutaneous electrical nerve stimulation after thoracic surgery: systematic review and meta-analysis of 11 randomized trials.

Objectives: To evaluate the effects of transcutaneous electric nerve stimulation (TENS) on pain and pulmonary function during the postoperative period after thoracic surgery by performing a systematic review and meta-analysis of randomized trials.

Methods: The search strategy included MEDLINE, PEDro, Cochrane CENTRAL, EMBASE and LILACS, besides a manual search, from inception to August, 2011. Randomized trials were included, comparing TENS associated or not with pharmacological analgesia vs.

Perioperative variables of ventilatory function and physical capacity in heart transplant patients.

Introduction: Heart transplantation is currently the only widely accepted surgical alternative to treat patients with severe heart failure (HF) drug therapy cannot maintain optimal quality of life appropriate.

Objective: To describe and to compare the values between pre-and postoperative physical capacity and pulmonary patients who underwent heart transplantation.

Methods: A retrospective cohort composed of patients undergoing heart transplantation between January 2001 to March 2005 in IC-FUC/RS.

Ventilatory profile of patients undergoing CABG surgery.

Objective: To assess the ventilatory, radiological and clinical profile of patients undergoing elective CABG in a cardiology reference hospital in South Brazil.

Methods: This study included 108 patients undergoing elective CABG surgery, in the period between April 2006 and February 2007 at the Cardiology Institute of Rio Grande do Sul (IC-FUC). The surgical procedure involved median sternotomy, and the saphenous vein and/or internal mammary artery were used for grafting.
