Active clinical trials for "Heart Diseases"

Fruit and vegetables are a cornerstone of healthy dietary patterns and dietary guidelines worldwide. The supporting evidence, however, is largely derived from observational studies of protective associations with cardiovascular disease (CVD) in health-conscious populations or from randomized trials of the effect of specific fruit or vegetable derived nutrients on CVD risk factors. A growing body of literature has influenced a shift away from a focus on single nutrients to a focus on whole foods and dietary patterns. To what extent fruit and vegetables should contribute to dietary patterns for cardiovascular health and whether specific types of fruit or vegetables should be recommended is unclear. Although previous systematic reviews and meta-analyses have elucidated the association between the intake of total and some specific fruit and vegetables with cardiovascular outcomes, a comprehensive synthesis comparing the certainty of the evidence for the different types of fruit and vegetables in relation to a range of cardiovascular outcomes has yet to be completed. We propose to conduct a systematic review and meta-analysis of the available prospective cohort studies using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the association between different types of fruit and vegetables and different cardiovascular outcomes that include CVD, coronary heart disease [CHD], and stroke incidence and mortality.

A study to evaluate the efficacy of MZ101 therapy in reducing liver stiffness.

Comparison of safety and long-term effects of BioMimeTM stent and Ultimaster® stent with Xience® stent

This study will assess the benefit in using a frailty score to quantify accurate risk pre-operatively in patients undergoing major cardiac surgery in order to predict morbidity and disability-free survival post-operatively.

The National Heart Centre Singapore has recently created a biorepository that is IRB approved for the use in genetic studies: "molecular and imaging studies of cardiovascular health and disease (CIRB Ref: 2013/605/C)". This repository enables IRB approved projects within the National Heart Centre Singapore to access the samples for use in biomarker or genetic studies with consent from patients for these studies. The IRB approved biorepository process also allows for patients, when they have consented to this, to be approached for inclusion in additional studies at National Heart Centre Singapore. In this study, the investigators will examine the genetic variation in genes known to cause inherited cardiac conditions and also look for circulating biomarkers (ICC) in 600 patients with ICC and in 500 patients with ischemic heart disease (e.g.IHD) who will be used as controls. Healthy controls will also be used (800) as they become available in the biorepository. All samples have already been collected in the NHCS biorepository. These patients would have been recruited and consented to the biorepository. This will enable all to better understand heart disease in Singaporean patients. In addition, the investigators will invite a subset of 10 patients with ICCs to provide a second blood sample (20mls - 2 tablespoons) on top of the samples that will be collected for the biorepository. The second blood sample will be used for antibody biomarkers that will be developed in the basic science laboratories. These antibodies will be used to develop new biomarkers of human heart disease to improve human health.

A multicenter, retrospective clinical study was carried out in the medical records management system of 6 hospitals in Tianjin. Patients who were suffered with Coronary heart disease angina pectoris and underwent coronary angiography are collected. The investigators collect and analyze the demographics, laboratory information, clinical outcome data, and coronary angiographic data of patients. To explore the correlation between hypercholesterolemia and the degree of coronary artery stenosis of Coronary heart disease angina pectoris, and to further research the influence of hypertension on total cholesterol level and coronary artery stenosis, and provide guidance for clinical prevention and treatment.

Chronic coronary syndrome (CCS) is a newly described classification devised by the European Society of Cardiology (ESC) 2019 to replace the term "Stable Coronary Artery Disease (CAD). The main reason for effecting the change is the term is thought to better describe the disease process and encompass a wider spectrum of clinical, pharmacological, and pathophysiological entities. Using this new term, the disease atherosclerosis manifests as CAD is categorized into Acute Coronary Syndrome (ACS) and CCS. The main focus of introducing the concept of CCS is on the fact that CAD is a continuous phenomenon involving intravascular plaque aggregation and progression which has different evolutionary phases. Dyslipidemia is recognized as a prominent risk factor for cardiovascular (CV) disease. It is characterized by an elevation of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), or triglycerides (TG) and reduced serum high-density lipoprotein cholesterol (HDL-C) concentration . Genetically determined and metabolically induced disturbances in lipid metabolism, as manifested in several types of dyslipidemia, have been shown to be causally related to the development of coronary artery disease (CAD). A diversity of clinical and angiographic studies has been made to evaluate the linkage between plasma lipid-control therapy in the development of recurrent cardiovascular events. Independent predictors of recurrent CVD events or death include age, smoking, hypertension (HTN), dyslipidemia, diabetes mellitus, chronic kidney disease, and the underutilization of medications recommended by current treatment guidelines.

High level of security during blood transfusion has been achieved by donor selection and pathogen detection using serology or direct identification. Nevertheless, blood banking becomes hazardous during epidemic outbreaks or facing new pathogens. Amotosalen, a psoralen, targets nucleic acids and destroys them after ultraviolet exposure, resulting in inactivation of pathogens. Treatment inoccuity and efficacy have been demonstrated but preservation of platelet functions after treatment is still debated. Previous studies focused on hematological patients. There is no evidence for an increased requirement of transfused platelets to achieve platelet count target. Studies in heart surgery are lacking. The investigators perform a multicenter, retrospective, "before/after", controlled study in minor patients requiring heart surgery with cardiopulmonary bypass. One center (Strasbourg) uses Amotosalen-treated platelet concentrates since 2006 (control arm). This treatment becomes available in Bordeaux in October 2017 (intervention arm). There is two periods of inclusion: one "before" (January 2016 to June 2017) and one "after" (January 2018 to June 2019).

Prosthetic paravalvular leaks (PVL) leading to heart failure and/or haemolysis can be treated by interventional cardiology or open-heart surgery. Predictors of clinical success of transcatheter closure remains little known and should be identified to help choose between these two options.Patient selection criteria for the best option are needed. The investigators aimed to identify predictors of clinical success after transcatheter PVL closure. Consecutive patients referred to 24 European centres for transcatheter PVL closure in 2017-2019 were included in a prospective registry (Fermeture de Fuite ParaProthétique, FFPP) and followed over 2 years
