Active clinical trials for "Angina Pectoris"

The goal of the ACCURACY study is to assess the differences, if any, in FFR measurements made by the OptoWire Deux FFR guidewire by comparison of simultaneous data of two different OptoWire DeuxTM guidewires (group 1). In addition, the investigators will compare (group 2) the FFR measurements obtained from an OptoWire Deux FFR guidewire and compare it to the FFR measurement by a VERRATA-TM guidewire to assess coronary stenosis in the routine clinical practice.

Low intensity shockwaves have been proven in animal studies to induce local growth of new blood vessels from existing ones. The hypothesis of this study is that shockwave therapy could improve the symptoms of patients with refractory angina not amenable to revascularization with angioplasty or bypass surgery.

Optical coherence tomography (OCT) after the stent procedure to improve the adhesion and expansion, or incomplete uncovered struts attached to the main track. OCT in clinical areas by improving the parameters of the best stent will be useful. However, for better results for optical coherence tomography in percutaneous interventions have little useful data on the role. Randomized controlled study of the traditional percutaneous coronary intervention and intervention using optical coherence tomography.

The purpose of this study is to determine whether coronary artery CT scanning or nuclear stress testing is better at diagnosing chest pain patients with coronary artery disease to select appropriate candidates for coronary catheterization and re-vascularization.

The register study CGM@CAD will examine whether cardiogoniometry can provide additional information concerning the indication for a diagnostic coronary angiography and if so, which additional value it has. Therefore, an additional cardiogoniometry will be carried out in consecutive patients who have been diagnosed with myocardial ischemia by means of established methods (exercise ECG, stress echocardiography, myocardial scintigraphy, or stress-MRT) and for whom an intracardiac catheter examination is regarded as indicated. The results of the different methods - particularly the results of the exercise ECG and the cardiogoniometry - will be checked against the results of the invasive examination as gold standard and the discharge diagnosis with regards to any correlation.

The post-marketing study is designed to evaluate the activity level and exercise tolerance of patients with deferred percutaneous intervention due to FFR (fractional flow reserve) greater or equal to 0.81 and treatment with Ranolazine versus placebo.

The investigators will check the feasibility of an intraprocedural vitality diagnostics and the identification of an indication for Percutaneous transluminal coronary angioplasty (PTCA).

This study used a multicenter, prospective cohort study. According to whether they received TCM treatment and the degree of exposure to TCM, the cohorts were divided into strong TCM exposure group, TCM exposure group, weak TCM exposure group and Western medicine exposure group. The first three groups received traditional Chinese medicine treatment combined with western medicine basic treatment, and the cumulative treatment time of traditional Chinese medicine reached 80%, 30%-79% or 30% of the total course of treatment, respectively. The fourth group received basic western medicine treatment alone. Among them, Chinese medicines (including Chinese patent medicines, Chinese medicine decoctions, Chinese medicine granules, and Chinese medicine injections) have been used and/or taken for a total of 5 months;

The purpose of this study it to collect real world 30-day and 1-year follow-up data for patients undergoing TMR with the CardioGenesis Holmium:YAG Laser System either as a sole therapy procedure or in conjunction with coronary artery bypass graft (CABG) surgery. The primary objective of this study is to provide ongoing clinical data regarding the characteristics of the patient population undergoing TMR in community practices. Secondary objectives include rates of postoperative mortality and MACE at 30-days and 1-year, and benefit of sustained improvement in angina at 30-days and 1-year. The study includes two patient populations: Registry Group: Patients from selected centers who previously participated in the ANGINA RELIEF Registry and are eligible for a one-year, prospective follow-up; Prospective Group: Up to 100 new, prospectively enrolled TMR patients from selected centers.

The primary objectives of this study are to evaluate the performance of StatSeal Advanced used in conjunction with the TR Band (SSA) as compared to the TR Band without SSA (TRB) relative to: the incidence of peri-procedural radial artery occlusion (RAO) at discharge or 24 hours, whichever occurs first, and the Time to Hemostasis (TTH).
