View clinical trials related to Angina, Stable.
Filter by:In Patients with stable Angina pectoris CCS 1-3 exercise testing for ischemia detection is widely used despite the known limitations. Measurement of the FFR is invasive but gold standard for Ischemia detection. Adding of parameters of spiroergometer might help to improve diagnostic accuracy of non invasive exercise testing. Therefore the trial is evaluating diagnostic accuracy of spiroergometric parameters compared to invasive FFR measurement.
The main purpose of this trial is to evaluate the efficacy and safety of Buqitongluo Granule in treating qi deficiency and blood stasis syndrome, and explore the effect of the improvement of qi deficiency and blood stasis syndrome on the prognosis of diseases.
The purpose of this study is to investigate the potential association of coronary artery geometry, based on coronary CT angiography (CCTA), with the complexity and the severity of coronary atherosclerosis.
The goal of the study is to assess the prevalence of contrast-associated acute kidney injury in patients with stable coronary artery disease, ST-elevation myocardial infarction and unstable angina/NSTEMI, assess the risk factors of contrast-induced acute kidney injury development and the influence of contrast-induced kidney injury on 1-year prognosis.
The present study aims to compare a planned angiographic control (PAC) follow-up strategy vs. conservative management for patients treated with drug-eluting stents on unprotected left main artery in a prospective, randomized setting. PAC will be performed by coronary computed tomography (CCT), to avoid the limitations of the invasive coronary angiography which is usually employed to perform PAC. The superiority of a PAC-based approach will be tested on a hard clinical end-point such as the incidence of major adverse cardiovascular events. The investigators will also assess the performance of CCT as a tool to perform PAC.
This study, designed as a retrospective registry, aims to investigate the relationship and potential interplay between fractional flow reserve (FFR) or instantaneous waves free ratio (iFR) with wall shear stress (WSS) in the context of intermediate coronary stenosis.
Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridian phenomenon are urgently needed. Therefore, this study is designed to assess the heat transport characteristics of meridian phenomenon for the Heart and Lung meridians by using infrared thermal imaging. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology.
Coronary artery disease (including stable angina and acute coronary disease) remains the leading mortality and morbidity worldwide. Improvement in biomarker, imaging research have led to new predictors for the prognosis, which may have great clinical value in the current era of personalized medicine. However, there is no available biomarker-based prediction rule for risk assessment of adverse events in patients with stable angina and acute coronary disease. Therefore, we aim to develop and validate a new biomarker-based risk model to improve the prognostication of adverse events (e.g. ischemic and bleeding events ) in the patient population.

Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridian phenomenon are urgently needed. Therefore, this study is designed to assess the metabolic characteristics of meridian phenomenon for the Heart and Lung meridians by using near infrared spectroscopy. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology.
