Active clinical trials for "Heart Diseases"

This study was designed to evaluate the correlation between pre-operative FFR and the functionality of arterial bypass grafts six months after coronary artery bypass grafting. Patients with multi-vessel coronary artery disease will undergo both a coronary angiogram and FFR during their diagnostic workup. All patients will be referred for surgical revascularization (CABG) with planned use of arterial grafts. Six months after surgery, patients will undergo an angiogram to assess the functionality of the bypass graft and anastomosis.

A prospective, multicenter, registered cohort study to observe the incidence of 1-year major adverse cardiac events in patients with coronary heart disease co-morbid depression treated with percutaneous coronary intervention and to clarify the predictors of 1-year major adverse cardiac events post PCI among these patients.

The main objection is to investigate molecular biology of myocardial damage during cardiac surgery procedures.

Many conditions affecting health are caused by a combination of environment, behaviors, and genes. While individuals can alter some factors in their lives to reduce the chances of developing different diseases (e.g., not smoking cigarettes), the contribution from genetic risk encoded by DNA remains with people throughout their lives. Scientists are still trying to determine the entirety of genetic factors that influence disease, but for some conditions it has been shown that the factors identified thus far can begin to identify people at high to low genetic risk. Looking across the genome, scientists can calculate a cumulative genetic risk score - which can be used to rank genetic risk compared to other worldwide populations. The goal of this study is to determine how genetic risk influences health decisions and other things that can be controlled in life. The first genetic risk score is calculated for coronary heart disease (CAD). CAD ultimately leads to heart attacks, heart failure and sometimes sudden cardiac death and is the main reason heart disease remains as the number one cause of death worldwide. Other researchers have shown that this genetic risk score can be used to identify people with low, intermediate, and high risk for coronary heart disease. It has also been shown that the use of statins (cholesterol lowering drugs) provides greater benefit and protection against heart attack for people with high genetic risk for coronary artery disease. Leveraging the Apple ResearchKit and the ResearchKit linked 23andMe API, customers of 23andMe are able to provide researchers access to their genomic data. Participants will use the ResearchKit app to provide consent, view study information, answer surveys, and contact the study team. Participants will be asked to complete 3 surveys. One before viewing genetic risk scores, one immediately after viewing scores, and one 6 months after viewing scores.

Ischemic Heart Disease (IHD) is a condition of recurring chest pain or discomfort that occurs when a part of the heart is not receiving sufficient blood flow. It is a major public health concern internationally and in Singapore, the leading cause of death from cardiovascular disease. Cardiovascular magnetic resonance (CMR) has the ability to assess heart structures, scarring or lack of blood supply to the heart muscle with great accuracy and without any radiation involved. A CMR-compatible cycle ergometer can offer a safe and low cost stress equipment to assess heart function and motion abnormalities, and restrictions of the blood supply to the heart tissues due to partial or complete blockages of the blood vessels. This study aims to develop an exercise-CMR stress protocol by testing its feasibility and robustness in assessing changes in cardiac volumes and function due to physical exertion in healthy individuals and to assess the accuracy of the multiparametric stress-CMR as a diagnostic tool for ischemic-causing coronary artery disease (CAD) with coronary fractional flow reserve (FFR) as a reference. to measure the overall economic impact of ischaemic heart disease by estimating the direct and indirect medical costs for each participant. The current sample costs will be extrapolated to estimate the annual costs of treating and managing ischaemic heart disease in the local population. to evaluate the effects of coronary microvascular dysfunction on coronary flow and regulation, physiological response and cardiac sympathetic signaling in patients with chest pain.

The registry for the improvement of postoperative outcomes in cardiac and thoracic surgery aims to prospectively collect data in order to test the association between various preoperative and per-operative variables ; and several postoperative outcomes such as mortality, shock, redo surgery, sepsis and extracorporeal life-support.

The overall goal is to identify trends and longitudinal associations in psychosocial, food-related, and cardiometabolic risk factors that can guide public health priorities and future research needs aimed at reducing cardiovascular-related disparities in Puerto Rico. To this end, investigators will establish 'PROSPECT: Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic disease Trends', an island-wide, longitudinal population cohort of 2,000 adults (30-75 years) in PR recruited with a community-wide sampling strategy, and assessed in a network of several partner clinics across the island. The study will collect comprehensive data on multiple psychosocial, dietary, and food-related factors, CVD biological markers, and medical record data, with follow-up at 2-years, and will assess variations by urban-rural area and by timing before-after Maria.

The objective of ENVISION is to evaluate the safety and effectiveness of the Navitor Transcatheter Aortic Valve Implantation (TAVI) System for treating patients with symptomatic, severe native aortic stenosis who are considered intermediate or low risk for surgical mortality.

Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European Registry for AAOCA (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres.

Immune checkpoint inhibitors (ICIs) might induce high grade immune-related adverse events (irAEs) involving the cardio-vascular system. This study investigates reports of cardio-vascular toxicity associated with treatment including anti-PD1, Anti-PDL-1, and Anti CTLA4 classes using the World Health Organization (WHO) database VigiBase, Assistance Publique Hopitaux de Paris Entrepot de Données de Santé (APHP.EDS), French Système National Des Données de Santé (SNDS) Databases and a retrospective international multicenter registry of ICI-associated myocarditis
