NCT ID: NCT04817488 Recruiting - Echocardiography Clinical Trials

Live Stream of Prehospital Emergency Ultrasound in Patients With Acute Dyspnoea

Start date: July 1, 2021
Phase:
Study type: Observational

Background: Acute dyspnoea is a common symptom in prehospital emergency medicine. As ultrasound gained in importance for diagnosis in patients with acute respiratory distress, it plays even a role in the prehospital setting. However, prehospital emergency ultrasound (PEU) remains challenging and requires knowledge and skills. New prehospital ultrasound devices offer the possibility for tele-supervision. The impact of tele-supervision of PEU in patients with acute dyspnoea is unclear. Objective: This prospective observational study aims to evaluate the effect of PEU with tele-supervision on diagnosis, treatment strategies and cognitive load in comparison to PEU without tele-supervision in patients with acute dyspnoea. Methods: In total 350 prehospital emergency patients with acute dyspnoea will be included in this study. Patients will be observed in two groups. In group 1 PEU will be performed with tele-supervision, whereas in group 2 PEU will be performed without tele-supervision (tele-supervision not available).

NCT ID: NCT04240067 Recruiting - Acute Heart Failure Clinical Trials

Multimarker Approach for Acute Dyspnea in Elderly Patients Admitted in the Emergency Department

READ-MA
Start date: June 1, 2018
Phase:
Study type: Observational

Elderly people constitute the largest proportion of emergency department (ED) patients, representing 12% of all ED admissions. The need for diagnostic tests or therapeutic interventions is much greater in this patient population. Cardiovascular diseases and symptoms represent 12% of the causes for ED admission, and patients suffering from cardiovascular disease are those whose ED visit lasts longest. The diagnostic approach in the ED in elderly patients admitted for acute dypsnoea is complex, and early identification of acute left-sided heart failure (ALSHF) is vital as it has an impact on prognosis. The clinical signs are difficult to interpret, and are non-specific, particularly at the acute phase and in elderly or obese patients. Indeed, some authors have reported up to 50% of diagnostic errors in elderly patients. Measure of the blood concentration of a natriuretic peptide allows a quick diagnosis. However, peptides alone suffer from several limitations, particularly in situations that are often encountered in elderly patients, such as sepsis, renal failure, acute coronary syndrome, pulmonary embolism, chronic respiratory failure, atrial fibrillation and high body mass index. Diagnostic performance deteriorates with increasing age, and there is a significant increase in this grey-zone in patients aged ≥75 years. In critical situations in elderly patients, assessment of natriuretic peptides serve mainly to rule out a diagnosis of left heart failure. Some authors have studied other biomarkers showing their performance in the diagnosis of ALSHF. These are biomarkers involved in remodeling and myocardial fibrosis (ST2, Galectin-3) or involved in myocardial injury (High-sensitivity Troponin-I). Therefore, a combined "multimarker" approach could improve the diagnostic performance of ALSHF. READ (NCT02531542) is a diagnostic study including patients over the age of 75 admitted to acute dyspnea in the ED, to demonstrate the superiority of an ultrasound protocol (the READ protocol) on NT-proBNP in the ALSHF diagnosis. The hypothesis is that the diagnostic accuracy of a multimarker diagnostic approach, namely the READ-MA method, combining NT-proBNP, High-sensitivity Troponin-I, ST2 and Galectin-3 would be superior to that of NT-proBNP assessment for the diagnosis of ALSHF in elderly patients (≥75 years) admitted to the ED.

NCT ID: NCT03194243 Recruiting - Acute Dyspnea Clinical Trials

Pathway and Urgent caRe of Dyspneic Patient at the Emergency Department in LorrainE District (PURPLE)

PURPLE
Start date: October 5, 2017
Phase: N/A
Study type: Observational

This is an observational prospective multicenter study of patients admitted for acute dyspnea in an emergency department of the participating centers in the Lorraine district. The primary objective is to assess the outcome of this population according to the cause of acute dyspnea as well as identify the predictors of this outcome, both overall and according to each acute dyspnea cause.
