Active clinical trials for "Heart Diseases"

Background: Anesthesia management in pediatric cardiac surgeries focuses on reducing morbidity and mortality, early mobilization and discharge, using health resources sparingly and increasing the quality of life of patients. The duration of postoperative mechanical ventilation is one of the most important factors affecting the process after pediatric cardiac surgery. Besides the view that postoperative mechanical ventilation is safe, there are opposing views that it causes an increase in complications; It caused disagreements about extubation times. In our study, we aimed to investigate the factors affecting extubation times after pediatric cardiac surgery. Methods: 72 ASA≥III pediatric patients undergoing cardiac surgery with cardiopulmonary bypass were included in our study. The patients were divided into 3 groups according to their extubation time. Those that were extubated in the operating room (OR) or in 6 hours after surgery (Immediate Extubation or IE), those that were extubated within 6-48 hours of admission to the ICU (Early Extubation or EE) and those that were extubated sometime after 48 hours or not extubated (Delayed Extubation or DE). Many variables of preoperative, peroperative and postoperative periods were recorded to see which factors correlated with extubation times.

This pilot study is to investigate the feasibility of obtaining medical grade audio phonocardiogram (PCG) recordings using a smartphone-based auscultation device in the first step. The ability to determine Valvular Heart Disease (VHD) (i.e., presence or absence of cardiac murmurs) using novel handheld CAA-devices shall be analyzed and first data on a smartphone-based auscultation in a hospital setting shall be collected. In further studies, the data provided from this study can be used to investigate the potential diagnostic use of such devices in the ambulatory and stationary care scenarios.

This study is a prospective, single-center clinical trial，Comparison of transthoracic echocardiography and coronary angiography in coronary heart disease using a paired-analysis clinical trial.This study is based on the basis of clinical screening for coronary heart disease.

Centralized Pan-Algerian Survey on the undertreatment of hypercholesterolemia. The purpose of this study is to establish the proportion of patients on lipid-lowering pharmacological treatment reaching the LDL-C goals according to the Third Joint European Task Force guidelines in the survey population.

Coronary heart disease is a very common condition caused by narrowings in the blood vessel supplying the heart. the investigators are studying new tests to diagnose heart disease. In this study the investigators plan to investigate a special scan called a PET/CT (Positron emission tomography/computed tomography) and a new type of CT (Computed tomography) scan to tell us about the flow of blood to the heart muscle.

Design: Observational - Cross study with followed up for 30 days. The Primary Objective is to realize a record that reflects a national overview of the role of cardiac catheterization in patients with congenital heart disease in hospitals distributed by geographic density of each region of Brazil.

This study will compare 3 dimensional intracardiac echo (ICE) with 2 dimensional ICE or transesophageal echo in patients with structural and valvular heart disease who are already scheduled to undergo a percutaneous intervention. Specifically those patients would be those scheduled for a PFO or ASD repair, mitral balloon valvuloplasty, diagnostic cardiac catheterization assessment of aortic stenosis and those undergoing transcatheter aortic valve replacement.

Multi-center, observational, U.S.-based longitudinal program. Data will be collected prospectively for 3 years. Individual physician feedback will be provided on data collected with the purpose of improving the management of patients - quality enhancement research initiative (QuERI) process from adult patients enrolled with a history of repaired Congenital Heart Disease (CHD).

Coronary heart disease (CHD) is one of the leading causes of mortality and morbidity. 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. Within a nation-wide and regional representative probability sample of hospitals in China, 14,000 CAG/PCI inpatient cases will be sampled randomly from 2001 to 2011. The sampled medical records will be reviewed and abstracted in the national coordinating centre, in order to evaluate the treatment pattern, outcomes, and cost for PCI, during the past decade. Basic data and innovative evidence will accelerate evidence-based clinical practice and policy making, and improve patients outcomes in future finally.
