Active clinical trials for "Heart and Blood Diseases"

The present study was designed to determine the prevalence of previously unknown impaired glucose tolerance and type 2 diabetes in patients with acute ST-elevation myocardial infarction subjected to acute PCI. Secondary, a possible association between inflammation, haemostasis and abnormal glucose regulation was studied.

The purpose of this study is to determine whether heart rate variability-like parameters are related to changes in the disease status of a subject that suffers from a disease that decreases the pumping function of the heart.

STUDY TYPE: Prospective, national , multicenter, and observational study. OBJECTIVE: To assess the incidence of AF in patients with cryptogenic stroke who have implanted an AF detection device during a period of 2 years. DEVICE: Reveal XT 9529 (SQDM) SAMPLE SIZE AND STUDY DURATION: 100 patients enrolled which will be followed during a period of 2 years.

The NUMEVOX cohort is intended to follow-up the macro and microvascular dysfunction in relation to adipose tissue repartition in patients with metabolic syndrome associated to liver steatosis, sleep apnea. Duration of the follow-up is 3 years for each patient entering the cohort.

The purpose of this study is to compare plaque burden in the coronary and carotid arteries 5 years after adjuvant radiotherapy in women with right sided breast cancer vs left sided breast cancer.

To validate the capability of non-invasive bio-image tests in prediction of significant coronary stenosis of symptomatic adults.

Left ventricular filling pressure (LVFP) has prognostic significance in patients with heart failure. Traditionally, it should be assessed by invasive method, as cardiac catheterization and Swan-Gung catheter. In advance of new techniques and modality, echocardiography provides some useful parameters for assessing LVFP, such myocardial tissue Doppler imaging. Many articles had documented that peak velocity of early-diastolic trans-mitral inflow velocity divided by early-diastolic velocity over mitral annulus correlated closely to LVFP. However, myocardial tissue Doppler only provides the information of regional myocardium, so patients with regional wall motion abnormality, as coronary artery disease, can't be assessed by this method without handicap. In addition, conduction disturbance, like bundle branch block, also influences the result of myocardial tissue Doppler. For resolving those problems, the investigators had designed a new global parameter to assess LVFP. In the investigators prior study, left atrial distensibility correlated logarithmically to LVFP in patients with severe mitral regurgitation and also in patients with acute myocardial infarction. Left atrial distensibility provided a new viewpoint to assess left ventricular diastolic function and to predict prognosis. This time, to extend left atrial distensibility to general population received echocardiographic examination for predicting prognosis is attempted.

The purpose of this study is to evaluate whether the serum apoB48 level is associated with atherosclerotic ischemic stroke.

The purpose of this study is to determine whether electroacupuncture preconditioning would provide protection against myocardial Ischemic-Reperfusion injury and systemic inflammation in children undergoing CPB for repair of congenital heart defects.

The carotid arteries are blood vessels in the neck that supply blood to the brain. Carotid stenosis disease is defined as a narrowing of these arteries due to the build up of plaque. The plaque material can also break off and move into the brain. The resulting blockage of blood supply to a portion of the brain is what causes 80% of all strokes. One treatment option is to have surgery on the carotid artery and remove the plaque. This procedure is called a carotid endarterectomy (CEA). There is evidence that proves CEA reduces the risk of stroke. The objective of this research project is to determine who is most likely to benefit from CEA surgery.
