Active clinical trials for "Dyspnea"

This study evaluates the prognostic value of arterial blood gas analysis in a cohort of Emergency Department patients presenting with shortness of breath of any cause, comparing obese and non-obese patients.

The purpose of this study is the psychometric validation of a self-administered dyspnea questionnaire, usable in clinical practice in order to assess dyspnea and its impact on patients with chronic respiratory diseases.

The purpose of this study is to determine the distribution of lung fluid status as reported by the IMED-4 system in patients presenting to the emergency department or urgent care facility with shortness of breath.

The purpose of this study is to evaluate whether new novel markers from the clinical electrocardiogram (EKG), which have been used as non-invasive measures of heart disease, can detect coronary artery disease in patients with chest pain. The researchers are especially interested in studying how changes in these unique waves evolve over time with rest and activity. It is hoped that the findings will be helpful in differentiating patients with cardiac chest pain at emergency departments from those with non-cardiac chest pain, as early identification can accelerate treatment and save lives. Eligible participants are those age 18 and older who have been referred for a nuclear stress test at University of Pittsburgh Medical Center Presbyterian Hospital to rule out coronary artery disease as part of their clinical care.

The purpose of this study is to evaluate the capacity of some novels biomarkers Procalcitonin (PCT), Midregional Proadrenomedullin (MR pro ADM), Midregional pro-atrial natriuretic peptide (MR pro ANP), Copeptin (CT pro arginine vasopressin), Pro endothelin to stratify the risk in severe dyspnea.

Acute heart failure is one of the main causes of acute respiratory distres in prehospital emergency setting. The early and correct diagnosis is important because the misdiagnosis can result in deleterious consequeance to patients. Rapid bedside tests (like NT-proBNP) and point-of-care lung ultrasound could be useful methods in field. This study confirmed that the combination of ultrasound sign in combination with rapid NT-proBNP test has a hibh diagnostic accuracy in differentiating between cardiac and pulmonray causes of acute dyspnea in the field and the tretament possibilities in clinical obscure cases are mainly improved.

This is a prospective registry of patients presenting with acute dyspnea to the emergency department of the city hospital in Nuremberg. There is evidence that acute dyspnea is associated with a mortality rate of 10%, however acute dyspnea is not perceived as a life-threatening condition, both in public and in health care providers. Our aim is to describe the patient collective concerning their demographics, baseline characteristics, type of referral and disposition, medical care processes and prognosis. Secondly, we want to evaluate if the subjective risk assessment of emergency department personnel matches with objective risk stratification tools and the actual outcome of the studied patients.

Vocal cord dysfunction is a rare clinical picture. It is labeled as a sudden and threatening dyspnea. Patients with VCD may also present cough, hoarseness, wheezing, and chest tightness, but an inspiratory stridor is the most common symptom. For this reason, such patients are often misdiagnosed with refractory asthma, because of poor response to steroids and bronchodilators. Diagnosis is suspected on clinical grounds and is confirmed with laryngoscopy. The therapy consists of education, speech therapy and if necessary psychotherapy. The purpose of the investigators' study is to characterize children, adolescents, and young adults with VCD, and the evaluation of predictors as atopy, bronchial hyperresponsiveness, and psychiatric features.

More and more general practitioners (GPs) use spirometry in their practices. At this time, there is sufficient reason to presume that, after a single postgraduate training program without any further support, most GPs have insufficient knowledge and ability to assure valid interpretation of their spirometry tests. Therefore, some kind of continuous diagnostic support with regard to spirometry interpretation by GPs is advisable. The aim of the present study is to assess whether implementation of spirometry expert support (either by a computerised expert system or a working agreement between general practitioners and respiratory consultants with respect to spirometry interpretation) causes changes in diagnosing and appropriateness and efficiency of medical care in subjects with chronic respiratory morbidity managed in general practice.

Obesity, defined as a Body Mass Index greater than or equal to 30 kg/m2, represents a significant public health issue. Dyspnea is a very common and crippling symptom in obesity. About 80% of people with obesity experience dyspnea in daily living. Bariatric surgery has been demonstrated to be an excellent treatment for obesity by inducing significant weight loss. Nevertheless, changes in dyspnea in daily living after bariatric surgery and the links between variations in dyspnea and lung function tests after bariatric surgery have not been previously investigated.
