Active clinical trials for "Heart Failure"

The aim of the study is to investigate the pathophysiological implications of transcatheter tricuspid valve edge-to-edge repair in patient with heart failure and preserved ejection fraction and severe tricuspid regurgitation. Changes in right- and left-ventricular function as well as the interventricular dependence will be analysed on a multimodal basis including pressure-volume loop analysis and cardiac magnetic resonance imaging.

The ability and timely selection of severe heart failure (HF) patients for cardiac transplantation and advanced HF therapy is challenging. Peak VO2 by cardiopulmonary exercise test (CPET) was used for transplant listing. This study aimed to reassess the prognostic significance of peak VO2 and to compare that with the Heart Failure Survival Score in the current optimized novel guideline-directed medical therapy (GDMT).

Depersonalized multi-centered registry initiated to analyze dynamics of non-infectious diseases after SARS-CoV-2 infection in population of Eurasian adult patients.

This study designed is compare the pulse response to the Valsalva maneuver between a photoplethysmography sensor (PPG) and non-invasive blood pressure sensor for the purpose of validating the PPG methodology in deriving a value for the Valsalva pulse response. The aim is to show that the PPG method captures the same phase responses as the blood pressure monitor and the primary outcome is the correlation between pulse amplitude ratios for the pulse at the end of the Valsalva to an average baseline pulse.

Chronic heart failure (CHF) is characterized by limited exercise performance, which is mainly determined by disease-specific factors, such as diminished cardiac output, abnormal ventilatory response, and low perfusion in skeletal muscles, which lead to skeletal muscle dysfunction.1 Exercise intolerance and symptoms may lead to activity restriction and further functional deterioration with the progression of CHF. There is some evidence that disease-specific self-report measures more quantify clinically relevant domains than measures of general health status and are generally more sensitive to clinical change. aim of the study is to investigate the validity and reliability of the PMADL-8 questionnaire in the Turkish population.

In this prospective validation study, researchers investigates accuracy of EHMRG (Emergency Heart Failure Mortality Risk Grade) score in predicting the 7th and 30th day risk of mortality in patients with acute heart failure who applying to the emergency department.

Acute Heart failure (AHF) is a common cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This association is frequently underestimated with regard to the difficulty of clinical diagnosis. The investigators expect that the application of the inferior vena cava collapsibility index (ΔIVC)could be useful in this issue.

To better understand the public health prognostic impact of noncardiac chronic illnesses, we explored the attributable risk of noncardiac comorbidities on outcomes between heart failure patients with reduced ejection fraction (HFREF) and heart failure patients with preserved ejection fraction (HFpEF) in a large contemporary heart failure (HF) population The adjusted hazard ratio (HR) and the population attributable risk were used to compare the contributions of 15 noncardiac comorbidities to adverse outcome. The comorbidities that contributed to high attributable risk were: anemia, chronic kidney disease, chronic obstructive pulmonary disease, diabetes mellitus, and peripheral artery disease. These findings were similar for HFrEF and HFpEF groups. Interaction analysis confirmed similar results.

The investigators wish to test a hypothesis that patients with HFpEF have different characteristics on echo, cardiac MRI and plasma protein & chemical profiles compared to HFrEF and healthy volunteers.
