Active clinical trials for "Heart and Blood Diseases"

is to test the hypotheses that epicardial adipose tissue can be a marker of severity of coronary artery disease in myocardial infarction patients

Peripartum cardiomyopathy (PPCM) is a global disease with significant morbidity and mortality of young women. Its' etiology, epidemiology and treatment is not yet well described. This will be a retrospective, national, multicenter observational study, conducted in Turkey. It is expected that approximately 50 women with PPCM will be recorded.

A nationwide observational study. Children operated with single-ventricle palliation between January 1994 and December 2017 operated in Sweden will be included retrospectively. Patients born with a functionally single ventricle but not undergoing surgery will not be included. Data regarding preoperative clinical characteristics and operative details will be obtained by medical records review and from The Swedish Registry of Congenital Heart Disease (SWEDCON). Using unique personal identity numbers assigned to all residents of Sweden, data from SWEDCON will be linked with dates of death.

This translational study was designed to explore the association of the quantity and quality of epicardial adipose tissue (EAT) with coronary artery disease (CAD), left atrial remodeling and postoperative atrial fibrillation in a high cardiovascular disease-risk population. The investigators expect to identify new biochemical factors and biomarkers in the crosstalk between the epicardial adipocytes, coronary plaques and atrial cardiomyocytes that are involved in the pathogenesis of atherosclerosis and atrial fibrillation, respectively.

The study aims to evaluate the decision-making pathways of interventional cardiologists, when assessing patients, presented with stable coronary artery disease.

To compare the 3 - year clinical follow - up results of patients with left main bifurcation lesions treated by intravascular ultrasound(IVUS) - guided and coronary angiography(CAG) - guided percutaneous coronary intervention(PCI), and to confirm the clinical benefits of optimizing interventional therapy of left main bifurcation lesions by intravascular ultrasound(IVUS).

The investigators combined the mRS questionnaire and BI questionnaire and then developed a telephone interview form as a simple questionnaire with internal rules. The main purpose of this study is to evaluate the validity and reliability of the telephone interview form when compared with face-to-face assessment in clinically stable patients with stroke.

To identify biomarkers of common eye diseases based on single-cell sequencing technologies using PBMC samples. These diseases include uveitis, diabetic retinopathy, age-related macular degeneration and polypoid choroidal vasculopathy. Our study may provide new insight into the underlying mechanisms, and reveal novel predictors and intervention targets for the diagnosis, prognosis and treatment of these diseases.

The purpose of this research study is to investigate the link between age-related macular degeneration (AMD or ARMD) and coronary artery disease (CAD). Age-related macular degeneration is a medical condition which may result in blurred or no vision in the center of vision. Coronary artery disease is a blockage of one or more arteries that supply blood to the heart. The study will specifically look at the macular changes that occur in the retina, which is the sensory membrane that lines the inner surface at the back of the eyeball, and the relationship between coronary heart disease and the risk factors.
