Active clinical trials for "Myocardial Infarction"

Heart disease is the number one cause of death in the United States, with over 650,000 deaths in 2019 alone. Many healthy individuals possess key risk factors for heart disease which include but are not limited to high blood pressure, high cholesterol, family history of heart disease, and diabetes. The purpose of the Genetesis Accelerated Registry (GEAR) study is to understand the potential for magnetocardiography to be utilized as a diagnostic, screening or surveillance tool for heart disease in healthy and non-healthy volunteers. Magnetocardiography (MCG) is a diagnostic method that analyzes and records the magnetic fields of the heart for the detection of various forms of heart disease. There will be a 12-month duration of the study where we propose to collect screening data from approximately 500 volunteers who present to the Genetesis facility for a 5-minute CardioFlux MCG scan. The volunteers will be contacted at intervals over a 1-year period for follow-up data and may choose whether or not they would like to provide follow-up data or participate in another scan.

BVS STEMI STRATEGY-IT is a spontaneous, prospective, non-randomized, single-arm multicenter registry on consecutive STEMI patients eligible to undergo primary percutaneous coronary intervention (PPCI) with BVS implantation on the basis of the pre-specified inclusion and exclusion criteria. This registry has the objective to assess the immediate (peri-procedural and 30 days), mid (6 months and 1 year) and long-term (3 and 5 years) results following BVS implantation using a pre-specified implantation strategy during PPCI in STEMI subjects.

The purpose of this study is to determine whether nicorandil reduce cardiac infarct size in patient with ST-segment elevation acute myocardial infarction.

Patients with acute ST-segment elevation myocardial infarction and thrombolysis indications, will be given the recombinant human prourokinase for thrombolysis treatment, and in accordance with the guidelines, will be treated with coronary angiography examination 3 to 24 hours after thrombolysis. The study will explore the best time for interventional therapy combined with thrombolysis.

To evaluate the influence of Salvianolate injection on myocardial microcirculation perfusion in subjects with STEMI who underwent primary PCI

In this study the investigators test the hypothesis that alteplase given intra coronary after PCI reduce infarct size in patients with ST-elevation myocardial infarction(STEMI) and impaired microvascular function defined as a value of index of microvascular resistance (IMR) >30.

Worldwide, more than 200 million patients have major non-cardiac surgery annually and a significant proportion of these patients suffer major cardiovascular complications (e.g. nonfatal myocardial infarction, cardiac arrest, vascular death) within 30 days of their surgery. Perioperative myocardial infarction is the most common cardiovascular complication and recent clinical studies have shown that even minor myocardial injury in relation to non-cardiac surgery is associated with 30-day mortality. Remote ischemic preconditioning is a procedure, which protects remote tissues and organs e.g. against ischemia-reperfusion injury. Cycles of forearm or leg ischemia and reperfusion by the inflation of a blood-pressure cuff for brief periods are the preferred method.The aim of this interventional clinical study is to determine whether remote ischemic preconditioning can reduce markers of myocardial injury in emergent or urgent non-cardiac surgery.

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).

Background: When an acute myocardial infarction occurs, the artery supplying the infarct zone should be opened within twenty four hours of onset of infarction. This has clearly been shown to be beneficial. If the patient presents later than 24 hours of onset, at that stage a large part of the damage to the heart is irreversible. Intervening at this stage (beyond 24 hours is controversial). Some trials suggest that opening the artery even at this stage positively modifies the remodeling process while other trials suggest that such a benefit is not seen. Hypothesis: Opening an infarct related artery after 24 hours (until 6 months) and combining it with intracoronary stem cell therapy may provide incremental benefit.It is possible that the lack of benefit seen with late revascularization (>24 hrs) after MI may be offset by giving intracoronary stem cells after opening the artery.

The investigators aimed to evaluated the role of bedside sleep medicine in an cardiology intensive care unit. The patients will be submitted to a overnight polysomnography. Those individuals with sleep apnea will be treated with CPAP during the ICU admission. Also, the investigators will identify the factors that compromise the sleep and will act to minimize them to improve the sleep quality. After the interventions, the investigators will evaluate if there are reduced days of hospital admission, major cardiovascular events (infarction, reinfarction, heart failure and stroke) and overall mortality.
