Long-term Outcome of Triple-vessel Coronary Artery Disease Underwent Three Different Strategies...
Coronary Artery DiseaseCoronary Stenosis1 moreThe study is to determine the long-term outcome of patients with coronary triple vessels disease (TVD) in the real world of China, by three different treatment strategies: percutaneous coronary intervention (PCI), Coronary artery bypass graft (CABG) or optimal medication therapy (OMT).
Clinical and Genetic Characteristics of Coronary Artery Disease in Chinese Young Adults
Coronary Artery DiseasePercutaneous Coronary InterventionThe aim of this study is to identify genetic loci,or gene variations contributing to the development of coronary artery disease (CAD) in Chinese young adults. Investigators will compare coronary angiogram results to genetic findings within young CAD patients.

Transluminal Attenuation Gradient Versus CT Fractional Flow Reserve
Coronary Artery DiseaseCoronary computed tomographic angiography (CCTA) has emerged as a non-invasive test, accurately evaluate anatomic coronary artery stenosis. However, anatomically-obstructive coronary stenosis by CCTA demonstrates an unreliable relationship to lesion-specific ischemia. Recently, with the advance of imaging reconstruction and analysis technique, several novel parameters computed from CCTA were suggested to have added value in determining the ischemia-causing coronary stenosis. In this study, diagnostic performance of transluminal attenuation gradient (TAG) and fractional flow reserve computed form CCTA (FFR-CCTA) for the presence of hemodynamically-significant coronary stenosis, as determined by fractional flow reserve (FFR).

MRI Perfusion Imaging at 3Tx Compared to Invasive FFR Measurements
Perfusion ImagingMRI2 moreCoronary artery disease (CAD) has a great significance concerning prevalence and mortality in the western world. It is usually diagnosed by catheterization and coronary arteries are visually assessed by the examiner. Thus having a great spectrum of interobserver differences, especially when it comes to intermediate lesions. The gold standard to assess the haemodynamic significance is the measurement of the myocardial fractional flow reserve (FFR). The FAME-study (Tonino, De Bruyne et al. 2009) was able o show that additional FFR- measurements in patients with intermediate lesions could significantly reduce stent implementation and consequently mortality. However this method is not used in daily routine and is available only in a fraction of catheter labs worldwide. Taking this into account decision finding especially in intermediate lesions remains difficult. One major step to simplify the invasive approach concerning intermediate lesions would be to establish a non-invasive procedures which localizes the coronary vessel to intervene ahead catheterization. Do to steady technical development cardiac MRI has become a powerful tool which is able to determine myocardial vitality, perfusion and function. In particular the new generation of 3 Tesla multi transmit MR with its higher field strength and better spatial resolution seems to be able to show first pass myocardial perfusion more precise. With this new technology prefixed to cardiac catheterization clinical relevant information can be made accessible and thus reduce the number of unnecessary implemented stents.
