Active clinical trials for "Myocardial Ischemia"

Single arm, prospective, multi-center, trial designed to enrol approximately 66 patients. All patients will undergo PCI using at least one RISE SC balloon as per routine clinical practice and will be followed until discharge for data collection. Patients will be enrolled in up to 5 investigational sites in Switzerland. The patients will be followed up until discharge or until 7 days, whichever comes first.

The DIAST-CMD registry (Prognostic Impact of Cardiac Diastolic Function and Coronary Microvascular Function) is prospective registry which enrolled patients who underwent echocardiography, cnically-indicated invasive coronary angiography and comprehensive physiologic assessments including fractional flow reserve (FFR), CFR, and IMR measurements for at least 1 vessel from Samsung Medical Center. Patients with hemodynamic instability, severe LV dysfunction (left ventricular ejection fraction<40%), a culprit vessel of acute coronary syndrome, severe valvular stenosis or regurgitation were excluded.

The aim of the present study will be to identify different phenotypes of microvascular dysfunction and their associations with the severity of anginal symptoms assessed through the Seattle Angina Questionnaire(SAQ-7).

The aim of this study is to assess the impact of culprit-first versus culprit-last percutaneous coronary intervention on the door to balloon time and clinical outcomes in patients with ST-elevation myocardial infarction.

The OPTIMUM registry is a minimal risk observational study that uses a prospective cohort design to follow patients who have multivessel or left main coronary artery disease ("surgical anatomy" according to ACC/AHA Appropriateness Criteria for PCI12) and are deemed ineligible for coronary artery bypass surgery. It is anticipated that 20 sites will be selected to participate in the registry from a national network of leading centers across the United States with recognized expertise in both complex PCI and coronary artery bypass surgery. We will invite leading cardiac centers, as defined by US News and World reports rankings for heart care. Additional sites may be added to meet the target enrollment goal.

Can Ayurvedic therapy improve markers of cardiovascular health and cardiovascular risk factors in patients with coronary artery disease.

Coronary artery disease is a leading cause of death, hospitalization, and health care costs in developed nations. Coronary revascularization with coronary artery bypass graft (CABG) surgery improves the long term survival in patients with diabetes and multi-vessel disease. Angiotensin converting enzyme inhibitors (ACE) and angiotensin receptor blockers (ARB) reduce mortality and subsequent cardiac events in patients with coronary artery disease undergoing CABG surgery when initiated at least 4 weeks pre-operatively. Observational data have suggested that pre-operative ACE administration is associated with an increased risk of post-operative vasoplegic shock, acute kidney injury, and mortality; however, other studies have failed to confirm these findings and further suggested ACE are associated with a reduced risk of peri-operative myocardial infarction. A single trial of 40 CABG patients randomized to pre-operative ACE withdrawal or continuation reported that the withdrawal group required significantly fewer vasopressors during cardiopulmonary bypass but more intravenous vasodilators post-operatively to control hypertension. Hence, it remains unclear whether ACEs should be held or continued immediately prior to CABG surgery and a survey of cardiac surgeons suggests that current clinical practice is divided. This pilot study aims to establish the feasibility of the study design and to determine the frequency of clinical endpoints among patients who continue and discontinue ACE prior to cardiac surgery.

This study is the sub-study of OPINION Trial. (UMIN000010580) The aim of this study is to evaluate how Optical frequency domain imaging (OFDI) or Intravascular Ultrasound (IVUS) imaging technology influence to the Percutaneous Coronary Intervention (PCI) strategy.

The study is a randomised comparison of recanalisation of chronic occluded coronary arteries with implantation of Sirolimus eluting stents and medical therapy. Myocardial function and scar-size are determinated by using magnetic resonance imaging. The study hypothesis is the superiority of medical therapy over revascularisation.
