Active clinical trials for "Myocardial Ischemia"

To conduct a randomized controlled smoking prevention trial to evaluate quality of implementation and effectiveness, as a function of provider type (school teacher vs. nurse) and training (mediated vs. interactive).

To measure serum concentrations of alpha tocopherol, selenium and all major carotenoids (alpha- and beta- carotene, lutein, (beta-cryptoxanthin and lycopene) in Black and white, male and female, high and low education individuals aged 18-30 in 1985-86. In subsequent renewals additional markers of oxidative stress and endothelial dysfunction have been measured in blood collected 7 to 30 years after baseline.

To examine the appropriateness of angiographic and ultrasound endpoints as predictors of subsequent clinical coronary events. Follow-up data from the Cholesterol Lowering in Atherosclerosis Study (CLAS) were used.

To examine the role of social support in attenuating ischemic responses to psychological stress, both in the laboratory and during daily life.

The primary objective of this study is to build a repository of resting cardiac phase space signals from eligible subjects using the Phase Signal Recorder (PSR) prior to coronary angiography for the purposes of machine-learning and testing algorithms developed by Analytics 4 Life. Male and Female subjects will be uniquely and consecutively enrolled into one group to support populating a repository of phase signals.

The purpose is to observe and evaluate the safety and efficacy of Bingo drug-coated balloon in the real world.

Coronary physiologic assessments by the pressure-derived fractional flow reserve (FFR) have become standard methods for identifying hemodynamic deprivation in coronary arterial stenosis for evidence-based percutaneous coronary intervention (PCI). Invasive physiologic indices-guidance enables on-site real time assessment for functional significance of epicardial coronary stenosis and the use of those indices has shown to be effective to guide treatment decision. Several studies further support the role of post-PCI FFR measurement as a functional marker of residual disease after PCI and prognostic indicator of patients. Although optimal cut-off values of post-PCI FFR varied across studies, an inverse relationship between post-PCI FFR and the risk of future clinical events have been reported consistently. Recently, non-hyperemic pressure ratios (NHPRs) have been introduced in clinical practice. Although there are several different NHPRs, previous studies consistently indicated that those NHPRs shares similar diagnostic performance and prognostic implications. Nevertheless, few reports were available for clinical relevance of NHPRs in evaluation of post-PCI status. In this context, we will evaluate the physiologic characteristics and prognostic implication of post-PCI NHPRs and compare with those of post-PCI FFR in patients who underwent angiographically successful PCI with 2nd generation drug-eluting stent implantation (DES).

To assess diagnostic accuracy,image quality and renal safety of a double low-dose coronary CTA protocol at coronary artery evaluation in patients with diabetes by using invasive coronary angiography(ICA) as the reference method and to compare the results with those obtained traditional dose protocol. The study will randomly include about 400 consecutive participants aged 18 to 80 years old who had been diagnosed with diabetes and suspected coronary artery disease.All participants undergo ICA and coronary CT angiography performed with a whole-heart CT scan.Coronary segment interpretability,image quality based on a four-point Likert scale,blood indicators of renal function will be accessed between double low-dose CTA protocol and traditional CTA protocol. Investigators hypothesize that an individualized coronary CTA protocol that appropriately reduces radiation dose and contrast dose does not affect image quality and diagnostic accuracy, and can reduce the risk of kidney damage in high-risk patients.

Study objective - to assess the efficacy, tolerability and adherence of bisoprolol/perindopril FDC in patients with HT and stable CAD in everyday practice. Type of the program: multicenter, observational, uncontrolled, open program. The program will involve 480 general practitioners (GPs) and cardiologists from the primary care facilities.Each doctor includes four patients. It is planned to include not less than 1920 patients in total.

The expression and quantification of Micro-RNA 146-a, was analyzed in the subgingival plaque samples of generalized chronic periodontitis patients with and without coronary heart disease. The demographic variables and periodontal parameters were assessed and correlated with expression of micro-RNA 146-a. The quantification of levels of micro-RNA 146-a was done using Real time Polymerase chain reaction. ( RT-PCR)
