Active clinical trials for "Dyspnea"

Despite advances in treatment and corresponding improvements in survival, patients with pulmonary arterial hypertension (PAH) remain highly symptomatic. In one survey of 315 patients with PAH, sixty-eight percent had moderate or severe dyspnea on exertion and 40% had a profound and clinically significant deficit in quality of life. Palliative care is being increasingly investigated in life-limiting cardiovascular diseases to alleviate symptoms. In PAH, its implementation is frequently delayed until end-of-life. Opioids are a common palliative care intervention, however the efficacy and safety of opioids for symptom relief in PAH has not been evaluated.

There is actually no physiologic or clinical data in the literature to clearly define the potential benefits and side effects of sublingual fentanyl in patients with COPD. Therefore, the purpose of this study is to test the hypothesis that sublingual fentanyl will improve exercise capacity and dyspnea control in severe COPD patients experiencing persistent breathlessness despite optimal management.

"Determination of the effectiveness of nebulized morphine in the treatment of dyspnea in patients with advanced idiopathic pulmonary fibrosis"

In recent months, more and more studies suggest tele-rehabilitation as a means to be exploited to reduce the risk of contagion. The intent of our study is to verify the effectiveness of a tele-rehabilitation intervention through the application of a respiratory rehabilitation program supported by contact with physiotherapists, in patients with outcomes from SARS-CoV-2 infection discharged from the various medical departments and taken over by physiotherapists after physiatric evaluation. Faced with the same rehabilitation program prescribed to all patients, the primary objective of our study is to detect whether patients supported by remote rehabilitation after hospitalization improve both adherence to the rehabilitation program and cardiorespiratory endurance and dyspnea symptoms assessed with the Six Minute Walking Test scale (6MWT). This test is validated for multiple pathologies, including idiopathic pulmonary fibrosis, the clinic of which could be comparable to the outcomes of coronavirus interstitial pneumonia as suggested by the literature. The secondary objectives concern the assessment of the impact of physical exercise assisted by tele-rehabilitation detected through: the assessment of the quality of life (Saint George Respiratory Questionnaire );the assessment of autonomy in daily life activities (Barthel Index Dyspnea Scale), the evaluation of the variation in thoracic expansion and lung volumes (with COACH , an instrument for respiratory physiotherapy that measures the inspiratory volume in ml); the evaluation of muscle strength and endurance (One Minute Sit To Stand) ; the detection of dyspnea during the execution of the exercises (Modified Borg scale); the assessment of the functionality of the lower limbs (Short Physical Performance Battery)

Objective: To estimate the effectiveness of muscle training, the degree of dyspnea and aerobic capacity in patients over 50 with COPD, in a health care institution provider in Antioquia. Question: What is the effectiveness of muscle training, in the degree of dyspnea and aerobic capacity in COPD patients over 50 years, in a health service institution provider in the department of Antioquia? Hypothesis: Muscle training causes changes in the degree of dyspnea and aerobic capacity, other than the breathing exercises and relaxation Design: Randomized clinical trial with allocation and blinding of the autcomes assesor. Participants: COPD patients stage II and II, male and female, over 50 years old, who are attending to a community health service provider in the department of Antioquia. Intervention: A physiotherapeutic intervention using PNF technique was applied to the experimental physiotherapy group versus Yoga sessions applied to the other group. Twelve weeks protocol performing three sessions per week. Outcome measures: Dyspnea degree and aerobic capacity was measured using the MMRC scale and the six minute walking test respectively at the begining and the end of the study.

The investigators are studying the effect of a single dose Opioid drug (Morphine) on dyspnea and exercise tolerance in COPD patients.

Researchers are examining the diagnostic utility of an exercise cardiac MRI (eCMR) in the assessment of cardiac dyspnea (shortness of breath).

Primary objective : to estimate impact of CT-scan on diagnostic for emergency department (ED) patients with suspected Community-acquired Pneumonia (CAP). Secondary objective: to estimate impact of CT-scan on treatment (antimicrobial therapy) and site of care for ED patients with suspected CAP.

For patients presenting to the Emergency Department with acute dyspnea, emergency physicians will be asked to categorize the diagnosis as acute decompensated heart failure or non-cardiogenic shortness of breath a) after the initial clinical assessment, and b) after performing lung ultrasound (LUS) for LUS arm or after chest radiography (CXR) and natriuretic peptide (NT-pro BNP) results for CXR arm. All patients will undergo CXR, those enrolled in the LUS arm, after sonographic evaluation. After discharge, the cause of patient's dyspnea will be determined by independent review of the entire medical records performed by two emergency physicians. In case of disagreement, a third expert physician will review entire medical records, and adjudicate the case.

The purpose of this study is to evaluate a validated diagnostic prediction model in the appropriate diagnosis of Acute Heart Failure (AHF) in patients presenting at the emergency department with undifferentiated dyspnea.
