Active clinical trials for "Angina, Unstable"

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 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.

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 primary outcome in this study will be time to discharge for low-risk patients and therapeutic turnaround time for patients with NSTEMI or unstable angina.

A randomized controlled, open label, multicenter trial with 1000 patients aged 70 years and older, presenting with Non-ST-elevation acute coronary syndrome. Patients will be randomized to either clopidogrel or the novel P2Y12 inhibitor (ticagrelor or prasugrel). Patients will be followed for one year for outcomes such as bleeding episode requiring medical intervention and net clinical benefit (all cause mortality, non-fatal myocardial infarction, non-fatal stroke, PLATO major and minor bleeding).

Coronary artery bypass grafting (CABG) among patients with reduced myocardial function remains a surgical challenge despite improvement in surgical technique, myocardial protection and postoperative care. Such cases are considered as high risk and associated with a higher peri-operative mortality than those with normal left ventricular function (LVF). Patients with low EF are at higher risks of sudden death, ventricular arrhythmia, and worsening heart failure due to recurrent ischemia. Therefore,early recognition of patients at risk for a worse outcome plays a pivotal role in the decision making process, allowing the prompt institution of an adequate support.

This is a prospective, randomized controlled trial. The aim of the study is to evaluate the impacts of a cardiac post-discharge management solution in the secondary prevention of Coronary Artery Disease (CAD).

Patients with NSTEMI and multivessel disease will be scheduled to undergo early invasive strategy (PCI within 72 hours) of de novo native coronary artery lesions were considered for recruitment into the study. Inclusion criteria are the following: diagnosis of NSTEMI according to current guidelines presenting with multivessel disease. We will exclude patients with cardiogenic shock at presentation (systolic blood pressure <90 mmHg despite drug therapy), left main coronary disease (>50% diameter stenosis), previous coronary artery bypass grafting (CABG) surgery, patients with Syntax Score >32 and candidated to by-pass surgery (10), severe valvular heart disease and unsuccessful procedures. Procedure success was defined as the achievement of an angiographic residual stenosis of less than 30% and a thrombolysis in myocardial infarction (TIMI) flow grade III after PCI. Patients randomized to One-Stage group were completely revascularizated in one time PCI, whereas patients randomized to Multi-Staged group were completely revascularizated in more time PCI, during the same hospitalization. Patients received a clopidogrel loading dose of 600 mg before the PCI (for loading dose administered more than 6 h prior to procedure). Post-procedural antiplatelet regimen consisted of aspirin at 100 mg/day indefinitely and clopidogrel 75 mg/day for at least one month.

To determine if estrogen therapy in postmenopausal women with unstable angina reduces the incidence of ischemic episodes.

This study aims to determine, relative to telemetry admission, if admission to an unmonitored floor bed saves resources without an increased rate of adverse events in emergency department (ED) patients admitted with chest pain and low-risk features.
