Active clinical trials for "Coronary Artery Disease"

The aim of this study is to determine whether a new vectorcardiogram (VCG) analysis will facilitate the detection of significant coronary disease (CAD) in patients with normal rest 12-leads ECG (NE).

The investigators plan to use retrospective data to assess heart function and structure abnormalities through the use of an approved vasodilating agent for stress cardiac MRI tests. The investigators are interested in how these MRI findings relate to long-term prognosis in people who are at risk for cardiac disease.

The investigator will evaluate the clinical outcomes of the patients in whom the treatment strategy for their coronary stenosis were determined by fractional flow reserve measurement.

Patients undergoing PCI for ACS are exposed to a significant ischemic and bleeding risk. The aim of our study is instead to analyze in detail the rates of recurrent events, but also their predictors and impact on outcomes, in a population of unselected real life patients treated with PCI for ACS discharged on either Clopidogrel, Prasugrel or Ticagrelor who already experienced an adverse event during the first year of follow up.

Identifying patients who are at risk for a future myocardial infarction, is still one of the biggest challenges in cardiology. In this study the investigators will investigate culprit lesion in patients with NSTEMI and the ability of cardiac CT with dual energy computed tomography (DECT) scanning to describe and identify plaques that may be vulnerable. The investigators will also describe changes in characteristic in both stable and unstable plaques during 1 year follow up of NSTEMI and a matching group of stable angina pectoris (SAP) patients.

this study is an individual patient level meta-analysis of randomized clinical trials, to evaluate the influence of ethnicity, to study whether the relative tradeoff between ischemia and bleeding is distinct by ethnicity.

All comer registry who had undergone intravascular optical coherence tomography during and/or after coronary intervention.

After PCI searching for target lesion ischemia with intracoronary ECG will be performed and if found it will be treated pharmacologically

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. Virtual stent implantation technique combined with QFR was recently developed to predict the functional significance of coronary stenosis as if the stenosis was revascularized. The purpose of this study is to evaluate the diagnostic accuracy of QFR in in tandem lesions with fractional flow reserve (FFR) as the reference standard. The secondary purpose is to evaluate the diagnostic accuracy of QFR-based virtual stent technique in predicting the FFR values after revascularizing the culprit lesion.

Coronary heart disease (CHD) has a serious health threaten to population. PCI is a well-proved measure in CHD management. However, the knowledge about the real-life PCI use and how evidence-based therapies in routine clinical practice is limited. In a large-scale hospital in Northeast China, the investigators will examine various factors of 3007 consecutive PCI inpatient cases from January 1, 2010 to October 31, 2014. The medical records will be reviewed and abstracted to evaluate the clinical treatment pattern and outcomes. Basic data and innovative evidence will accelerate evidence-based clinical practice, and improve patients' outcomes in future finally.
