Active clinical trials for "Heart Diseases"

Coronary heart disease (CHD) pose a serious health threaten to population. PCI, as a well-proved and booming measure in CHD management, is invasive and of high cost, however the knowledge about the real-life PCI use in China is limited. By consecutively recruiting PCI patients in 30 geographically representative highest-rank hospitals, this study will examine various real-life factors, that may affect patients recovery after the procedure. Practical guidelines, appropriateness criteria and quality evaluative system for PCI will be established based on the findings, to improve patients outcomes in future finally.

Coronary heart disease (CHD) pose a serious health threaten to population. Optimal revascularization strategy in multiple vessel coronary artery disease patients remains a subject of debate between interventional cardiologists and surgeons. Knowledge about the real-life revascularization pattern and outcomes in China is limited. By consecutively recruiting three vessel coronary heart disease patients in 25 geographically representative highest-rank hospitals, this study will examine revascularization strategy, and various real-life factors, that may affect patients lone-term recovery. Practical guidelines, appropriateness criteria and quality evaluative system for revascularization strategy will be established based on the findings, to improve patients outcomes in future finally.

The PRESET Registry--A Registry to Evaluate Patterns of Care Associated With the Use of Corus CAD (Age/Sex/Gene Expression score - ASGES) in Real World Clinical Care Settings (PRESET)--was designed as an observational, post-market, real-world registry to evaluate patterns of care, including referrals to a cardiologist, cardiac stress testing, CT angiography, within the first month after Corus CAD (ASGES) testing.

The investigators intend to prospectively enroll consecutive patients, without known ischemic heart disease, referred by their physician for routine exercise MPI at a tertiary care center. Prior to the MPI (nuclear stress test), eligible and consenting patients will undergo a one-hour period of Holter ECG digital recording. Application of ECG electrodes will be performed by medical technicians following standard recommendations, utilizing approved Holter device & stickers. The Holter ECG data will be used for the offline heart rate variability (HRV) analysis by the HeartTrends device. Immediately following data acquisition, all patients will undergo an exercise MPI according to accepted clinical practice guidelines. Following the MPI, there will be no interference with patient management, which will be conducted by the patients' treating physicians according to current guidelines, unaware of HRV results. Analysis of recorded ECG data for HRV will be performed blinded to the EST and MPI results, by HeartTrends device. The results of the HRV tests will not be available to treating physicians and will not be used to guide patient management. Patients will be followed for 6 months for the occurrence of coronary interventions and MACE, defined as: death, myocardial infarction, unstable angina, or any coronary revascularization.

A study about accuracy of pulse oximeter with hypoxemic measurements (Blue sensor, Masimo, Irvine, CA, USA) in children with cyanotic congenital heart disease

Patients with hypoplastic left heart syndrome and other single right ventricle lesions who have undergone the Fontan procedure have a high risk of neurodevelopmental disorders that affect quality of life and adulthood employment. This study will leverage the ongoing National Heart, Lung, and Blood Institute (NHLBI)-funded Single Ventricle Reconstruction Study by using innovative graph measures of brain connectivity to elucidate how alterations of the "connectome" in children with critical congenital heart disease are associated with developmental disabilities and their associated clinical risk factors. Improved understanding of these interrelationships may facilitate development of targeted interventions to improve outcome in the soaring population of adult Fontan survivors.

The goal of this study is to find out if there is any association between a mother's exposure to bacteria that normally causes "strep throat" and her baby's developing heart disease/heart defect.

Transcatheter Aortic Valve Implantation (TAVI) indications are progressing rapidly as an alternative to conventional surgery for aortic stenosis cure. Despite a high rate of procedural success, some patients do not benefit from the procedure. The investigators hypothesis is that aortic stiffness may be of major prognostic significance after stenosis relief. The aim of this study is to test the prognostic impact of aortic stiffness estimated by the volume of calcifications of the thoracic aorta on the CT-scan performed systematically before the procedure. This prognostic value will be assessed in 4 independent cohorts issued from 4 french cities (Lyon, Rouen, Paris, Clermont-Ferrand).

Currently, both oral and written health education make certain assumptions about the health literacy of patients and their parents. The prevalence of health literacy issues is unknown in the adult congenital heart disease (CHD) population. Having a better understanding of a patient's and/or their parents' health literacy will help us develop appropriate education and teaching tools to meet the patient's and their parents' needs.

The study is about comparing blood samples obtained from the superior vena cava and the pulmonary artery. The investigators will compare the values of PCO2 and PO2 from these two sites, in order to see if exists a PCO2 gap and a PO2 gap, different from zero. Moreover the investigators want to find out if these gaps are related with changes in the cardiac output, the hematocrit or if they can predict post operative dysfunctions. Blood samples will be taken at six different times as scheduled by the protocol. Along with the two venous blood samples, an arterial blood sample will be taken too, from a radial of femoral artery catheter.
