Filter by:The main goal of our investigation is to study the mechanisms of formation of left ventricular remodeling in patients with hypertension, working on a rotational expedition basis in the Arctic.
This pragmatic clinical trial embedded in an accountable care organization will determine the comparative effectiveness of two approaches for assigning care coordinators to older adults at risk for cardiovascular outcomes. The hypothesis is that assigning care coordinators to older adults based on perceived need will be more effective at preventing emergency department visits and hospitalizations compared to usual care.
Heart failure with preserved ejection fraction nowadays affects about half of all patients with heart failure. In the general population, the prevalence of this subclass of heart failure (HFpEF, ed.) increases as the age of patients increases, especially in those over 65 years of age, and it has a significant gender. The study is to investigate the molecular pathways, predominantly protein patterns, involved in cardiac remodeling peculiar to heart failure with preserved ejection fraction (HFpEF) by comparing them with remodeling pathways and protein pattern alterations in patients with HFrEF. In addition, the study aims to identify molecular alterations that would allow early identification of the development of PH-HFpEF and PH-HFrEF, affecting the female gender more
Early Feasibility Study of the FIRE1™ System in Heart Failure Patients to evaluate the feasibility and safety of implanting the FIRE1 system in stable HF patients
Pulmonary vein isolation (PVI) is currently the cornerstone non pharmacological therapy for drug-refractory atrial fibrillation (AF). Where rhythm control has been shown to be inferior as compared to rate control in older trials. New data suggest that for patients with heart failure and AF PVI may improve prognosis (mortality) as compared to medical rate or rhythm control. Whether optimal rate control as can be achieved with atrioventricular node ablation is comparable with regard to all-cause mortality of heart failure hospitalization to PVI in patients with heart failure and AF is unknown.
Chronic heart failure represents an extremely complex clinical syndrome, defined as the inability of the heart muscle to generate a volume adequate to the metabolic needs of peripheral tissues, or to do so only in the face of high filling pressures intracavity. Heart failure is one of the leading causes of mortality and morbidity in Western countries. Despite advances in the therapeutic field, the prognosis of patients with heart failure of ischemic and non-ischaemic aetiology still remains unfavorable, with a mortality rate of 50% 5 years after the first hospitalization.Therefore, a deeper understanding of the pathophysiological mechanisms involved in heart failure and adverse ventricular remodeling is essential.
More than 400 million people have type 2 diabetes (T2D) globally, and the burden of diabetes-related cardiovascular complications is increasing. Cardiovascular disease (CVD) affects approximately one-third of all individuals with T2D and accounts for half of all deaths in this population despite major advances in the treatment of the disease. Among the different types of CVD, heart failure (HF) is frequently the first CVD manifestation in individuals with T2D. Although the link between T2D and CVD is widely recognised, the absolute risk of cardiovascular events varies among individuals with T2D. As such, effective risk-stratification tool that accurately identify T2D patients at the highest risk of developing incident or recurrent cardiovascular (CV) events is needed. B-type natriuretic peptide (BNP) and its inactive N-terminal precursor NT-proBNP are biomarkers of myocardial stress. They been shown to incrementally improve predictive discrimination of death and CV events in high-risk individuals with T2D. An NT-proBNP-based CVD/HF risk stratification strategy has not been prospectively tested in the multi-ethnic T2D population in Singapore. In this study, we aim to: 1. Evaluate the predictive value of NT-proBNP for death and CV events compared to traditional risk markers [e.g. HbA1c, albuminuria, high sensitivity C-reactive protein (hsCRP), high sensitivity troponin-T (hsTnT)] in a cohort of T2D patients with or without established CVD (defined as ischaemic heart disease, myocardial infarct, unstable angina, prior coronary artery revascularisation, stroke, transient ischaemic attack or PAD) attending a tertiary diabetes care centre. (Patients with history of HF will be excluded.) 2. Compare the performance of NT-proBNP as a single biomarker for CV risk prediction to risk scoring algorithms in T2D patients.
prospectively evaluation the safety and efficacy of the Sodium-glucose Cotransporter-2 (SGLT2) inhibitor dapagliflozin in non-diabetic patients with heart failure and a reduced ejection fraction
The aim of the study is to determine the analytical characteristics of the microRNA enzymatic immunoassay (miREIA) method and to determine various relations among miRNA biomarkers and heart failure (HF) with reduced ejection fraction(HFrEF). The investigators assume that there are correlations between levels of selected miRNA and HFrEF. These correlations provide information to formulate pathophysiological conclusions, which will significantly contribute to early diagnostics and also the treatment of this disease.
Patients hospitalized with tachypnea, defined as respiratory rate ≥20/ min, have substantial mortality and may suffer from different conditions, including acute heart failure (HF). Symptoms of HF can be difficult to identify and ~15% of patients with HF will not be correctly diagnosed by the treating physician in the Emergency Department. Biomarkers like B-type natriuretic peptides and cardiac troponins improve diagnostic accuracy and risk stratification. Whether early, structured biomarker assessment and structured feedback in the patient's electronic health records improve management and outcomes among unselected patients with tachypnea have previously not been explored in a randomized controlled trial. The main research question of the study is to determine whether early structured biomarker assessment in unselected patients with tachypnea extends the time to the first event for either (1) all-cause readmission or (2) all-cause mortality; i.e. time to the combined endpoint, compared to the current strategy/standard care
