Active clinical trials for "Coronary Disease"

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.

Examination of probable distinction between cardiac or non- cardiac thoracal disorder via echocardiographic myocardial strain analysis

The investigators are going to recruit patients who have a scheduled elective coronary angiography and going to do a dobutamin stress echography (DSE) before the coronary examination. Next to a regular 2D-DSE, the investigators will perform an 3-dimensional DSE, incl ventriculography. In the interventional part (coronary angiography), they will measure each stenosis with fractional flow-reserve (FFR)and herewith graduate its stenosis severity.

The purpose of this study is to compare optical coherence tomography (OCT) scans performed in the same coronary artery with two different OCT systems (Lunawave and OPTIS) before and after implantation of stents or bioresorbable scaffolds.

In this study, the investigators hypothesized that significant proportion of patients with coronary artery disease (CAD) has reduced capacity of glucagon-like peptide-1 (GLP-1) secretion, which is detectable as blunted response of plasma active GLP-1 level to oral glucose loading and that reduced GLP-1 secretory function is associated with increased severity of coronary artery stenosis but not with classic risk factors for CAD. To test this hypothesis, the investigators will analyze correlation between GLP-1 secretory capacity and severity of coronary artery stenosis determined by Gensini Score (GS), an established score system for coronary artery stenoses. Additionally, the investigators will analyze relationship between level of "total" GLP-1 and severity of coronary artery stenosis to determine how it is different from the active GLP-1 - coronary stenosis relationship.

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.

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.

This is a multi-center, prospective, non-randomized, double-blinded trial to evaluate the sensitivity and specificity of the CADence device in detecting the existence of clinically significant coronary artery disease as determined by either standard or CT angiography.

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.

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.
