Cardiopulmonary Exercise Testing With Simultaneous Echocardiography After Pulmonary Embolism.

Although current guidelines recommend standard cardiopulmonary exercise testing (CPET) to evaluate symptomatic patients after pulmonary embolism (PE), CPET with simultaneous echocardiography could provide relevant information to evaluate right ventricular-pulmonary arterial coupling. The aim of this study was to investigate exercise-induced changes in echocardiographic variables of RV function or RV- arterial coupling in patients with residual thrombotic defects at 3 months after PE. This retrospective study investigated patients with residual thromboembolic disease on V/Q scintigraphy with persistent symptoms despite adequate anticoagulation after 3 months of acute PE, and resting echocardiography with a low probability of PH.

Effects of Exercise Training on Circulating Biomarkers of Endothelial Function in Pulmonary Arterial Hypertension.

Introduction: In stable patients with pulmonary arterial hypertension (PAH), pulmonary rehabilitation (PR) is an effective, safe and cost-effective non-pharmacological treatment. However, the effects of PR on vascular function have been poorly explored. This study aimed to compare the amounts of circulating progenitor cells (PCs) and endothelial microvesicles (EMVs) in patients with PAH before and after 8 weeks of endurance exercise training as markers of vascular competence.

Intravenous Iron Replacement Improves Exercise Tolerance in COPD: A Single-Blind Randomized Trial.

Introduction: Iron deficiency affects exercise capacity because of the critical role iron plays in the optimal functioning of skeletal muscle metabolism. We hypothesized that intravenous iron may improve exercise tolerance, quality of life (QoL), and daily physical activity (DPA) in patients with chronic obstructive pulmonary disease (COPD).

Methods: This was a placebo-controlled, single-blind, parallel-group, randomized clinical trial.

Impact of high-flow oxygen therapy during exercise in idiopathic pulmonary fibrosis: a pilot crossover clinical trial.

Background: Supplemental oxygen delivered with standard oxygen therapy (SOT) improves exercise capacity in patients with idiopathic pulmonary fibrosis (IPF). Although high-flow nasal cannula oxygen therapy (HFNC) improves oxygenation in other respiratory diseases, its impact on exercise performance has never been evaluated in IPF patients. We hypothesized that HFNC may improve exercise capacity in IPF subjects compared to SOT.

CT imaging of pulmonary embolism in patients with COVID-19 pneumonia: a retrospective analysis.

Objectives: To describe imaging and laboratory findings of confirmed PE diagnosed in COVID-19 patients and to evaluate the characteristics of COVID-19 patients with clinical PE suspicion. Characteristics of patients with COVID-19 and PE suspicion who required admission to the intensive care unit (ICU) were also analysed.

Methods: A retrospective study from March 18, 2020, until April 11, 2020.

Feasibility, tolerability, and effects of exercise-based prehabilitation after neoadjuvant therapy in esophagogastric cancer patients undergoing surgery: an interventional pilot study.

Patients requiring surgery for locally advanced esophagogastric cancer often require neoadjuvant therapy (NAT), which may have a detrimental impact on cardiorespiratory reserve. The aims of this study were to investigate the feasibility and tolerability of a 5-week preoperative high-intensity interval training program after NAT, and to assess the potential effects of the training protocol on exercise capacity, muscle function, and health-related quality of life (HRQL). We prospectively studied consecutive patients with resectable locally advanced esophageal and gastric cancer in whom NAT was planned (chemo- or chemoradiotherapy).

Level of daily physical activity in chronic obstructive pulmonary disease (COPD) patients according to GOLD classification.

Introduction And Objective: The Global Initiative for Chronic Obstructive Lung Disease (GOLD guideline) for patients with chronic obstructive pulmonary disease does not adequately reflect the impact of the disease because does not take into account daily physical activity (DPA).

Patients And Methods: Forty eight patients (12 in each GOLD group) were prospectively recruited. DPA was evaluated by accelerometer.

Right Ventricular Response During Exercise in Patients with Chronic Obstructive Pulmonary Disease.

Aim: Right ventricular (RV) pump function is of essential clinical and prognostic importance in a variety of heart and lung diseases. While the evaluation of RV performance at rest has been implemented in the clinical setting, it is unknown whether this assessment during exercise may provide additional benefit. With this aim, we evaluated the exercise-induced pulmonary arterial systolic pressure (PASP) increase during exercise in patients with severe chronic obstructive pulmonary disease (COPD) as an expression of RV contractile reserve.
