Filter by:The investigators propose a small pilot proof of concept study to not only prove the existence of, but also probe the mechanisms underlying cardio-renal effects of empagliflozin in patients with heart failure. The investigators propose a 50 patient randomized, double-blind, placebo-controlled crossover study with patients with stable HF, type II diabetes and an eGFR >45ml/min/1.73 m2 who are chronically receiving loop diuretics.
Sleep-disordered breathing is believed to appear at a high prevalence in end-stage heart failure patients and the presence of sleep-disordered breathing has been associated with increased mortality. This study is designed to investigate prevalence and dynamics of sleep-disordered breathing in end-stage heart failure patients pre and post heart transplantation.
About 50% of all patients suffering from HF exhibit a reduced ejection fraction (EF ≤ 40%), termed HFrEF. The others may be classified into HF with midrange EF (HFmrEF, EF = 40-50%) or preserved ejection fraction (HFpEF, EF ≥ 50%). Up to now, there are no large scale studies evaluating patients with HFmrEF and/or HFpEF in Turkey. Scarce data are available in the middle-east populations in general and Turkish patients in particular, who have different etiology, ethnic, cultural backgrounds and risk factors from those patients in the West. The aim of this study was to study Turkish patients with HFmrEF and HFpEF, and define their clinical characteristics and the signs and symptoms of heart failure, echocardiographic findings and medications at admission. With this national study, we will evaluate how recommendations of most recent European guidelines regarding pharmacological and non-pharmacological treatments are adopted in clinical practice. We will also evaluate the prevalence of the clinical profiles of patients with HFmrEF and HFpEF, according to the definitions proposed by the European Society of Cardiology, and to investigate their appropriateness in characterizing patients with different clinical presentations and needs. Assessed outcomes included the causes of decompensation, use of medications, care quality indicators.
The purpose of this clinical investigation is to report the long term survival and incidence of adverse events in the patients who were implanted with HM3 in the CE Mark Study and continue to be ongoing with the HeartMate 3 LVAS after the CE Mark Study 2 year follow-up. The study will be a single arm, prospective, multi-center, non-blinded and non-randomized study, intended to report on the long term use of the HeartMate 3 LVAS in those patients that completed the 2-year follow-up in the HeartMate 3 CE Mark study.
People with cardiovascular risk (CV) factors (obesity, diabetes, etc...) or established heart disease (such as coronary heart disease or chronic heart failure) often have cognitive dysfunction as compared to people without CV risk factors or heart disease. Among the mechanisms, a reduced cardiac output and cerebral blood flow in those people have been suggested. The aim of this study was to compare resting cognitive function, maximal cardiopulmonary function, cardiac output and cerebral hemodynamics during exercise in patients with metabolic syndrome, coronary heart disease, or heart failure vs. healthy subjects.
This study is designed as a multi-center prospective observational study of newly diagnosed Heart Failure (HF) patients to test the hypothesis that additional Ejection Fraction (EF) recovery occurs between 90 and 180 days as Guideline Directed Medical Therapy (GDMT) is achieved. Although the study doesn't start until day 90, all eligible, consenting patients will be entered into a registry at the start of wearable cardioverter defibrillator (WCD) use. The pre-study registry will allow us to collect early (90 day) outcomes and data in those patients who are likely to be eligible for the study at day 90, or are eligible, but refuse the study at day 90.
A Study to Evaluate Safety and Efficacy of Continuous 48-Hour Intravenous Infusions of HNO Donor in Hospitalized Patients with Heart Failure and Impaired Systolic Function
The main objective of this study is to determine the clinical efficacy of oral inorganic nitrite verses placebo and the therapeutic response with regards to exercise tolerance in patients with pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF).
The purpose of this study is to: To determine the rate and routes of excretion of BIA 5-453 and the mass balance in urine and faeces
The purpose of the LEVEA study is to assess the performances of a new automatic left ventricular auto threshold (LVAT) algorithm (In-Clinic LVAT algorithm) when used by physicians during in-hospital follow-up.
