In this study, we assessed the effect of rehabilitation exercise after percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD). We performed a meta-analysis to determine the effects of exercise in patients after PCI. The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, the Embase database, China National Knowledge Internet (CNKI), China Biology Me...

OBJECTIVE To investigate the modulatory effects that dynamic hyperinflation (DH), defined as a reduction in inspiratory capacity (IC), has on exercise tolerance after bronchodilator in patients with COPD. METHODS An experimental, randomized study involving 30 COPD patients without severe hypoxemia. At baseline, the patients underwent clinical assessment, spirometry, and incremental cardiopulm...

BACKGROUND The incremental shuttle walking test (ISWT) is used to assess exercise capacity in patients with chronic obstructive pulmonary disease (COPD) and is employed as an outcome measure for pulmonary rehabilitation. This study was designed to establish the minimum clinically important difference for the ISWT. METHODS 372 patients (205 men) performed an ISWT before and after a 7-week outp...

BACKGROUND Green tea intake has been shown to improve endurance capacity in animal studies, but whether it has a similar effect on humans remains unclear. A randomized, double-blinded, parallel-controlled study was conducted to evaluate the short-term effect of STA-2, a pharmaceutical preparation of green tea polyphenols, in patients with effort-induced angina and documented positive exercise t...

Despite improved prognosis for patients with cystic fibrosis (CF), they continue to suffer from progressive decline in pulmonary function and exercise tolerance. Beyond puberty, female patients have greater loss of pulmonary function and higher mortality than males, yet no one has studied male-female differences in exercise tolerance among patients. We therefore compared the responses to progre...

Adult congenital heart disease (ACHD); Cardiac surgery; Clinical feature; Exercise tolerance testing; Brain natriuretic peptide (BNP) Abstract Purpose: The aims of our study are twofold: first, to retrospectively identify the demographic characteristics and outcomes in cardiac surgery for adult congenital heart disease (ACHD); second, to explore whether certain preoperative examinations are use...

Endothelial dysfunction (ED) is an early pathophysiological change in patients with impaired glucose tolerance (IGT) during prediabetes mellitus. This study was designed to test the hypothesis that exercise intervention contributes to the reversal of vascular endothelium-dependent dysfunction in middle-aged patients with IGT. Following exercise intervention, significant changes in endothelin (E...

The hemodynamic and antianginal effects of 30 mg of isosorbide dinitrate (ISDN) were assessed in 12 patients with chronic stable angina after initial dosing and after 7 to 10 days of therapy four times daily. During early therapy, ISDN produced significant hemodynamic and antianginal effects that persisted over a 3 hr observation period. During sustained therapy there was attenuation of the hem...

We measured lung function and exercise tolerance in 15 adults with moderate kyphoscoliosis (thoracic curvatures between 25 degrees and 70 degrees, mean +/- SD = 46.93 degrees +/- 14.02 degrees). Forced vital capacity showed a slight reduction from values predicted from age and sex matched control subjects (3.39 +/- 1.06 vs 4.06 +/- 0.82 L, p less than 0.05). However, exercise tolerance was sign...

BACKGROUND Respiratory rehabilitation programs (RR) are essential tools in the management of COPD. AIM We present the results of a 7-week outpatient rehabilitation program in terms of dyspnea, exercise tolerance and quality of life. MATERIAL AND METHOD The following parameters were evaluated before and after RR: dyspnea (mMRC scale), pulmonary function (FEVI, RV- residual volume), exercise ...
