Active clinical trials for "Myocardial Infarction"

The aim of this registry is to collect clinical data on nitinol self-expanding STENTYS Xposition S™ in order to evaluate the efficacy and safety in patients presenting with ST segment elevation myocardial infarction

A number of studies have suggested an association between the use of antipsychotic agents and cardiovascular mortality. However, the relationship between cardiac events and the use of antipsychotic drugs is not clear. Patients experiencing psychoses and in need for antipsychotic agents may be at a higher risk of cardiac events regardless of any effect of antipsychotic medication. Two studies have specifically investigated the association between the use of antipsychotics and the risk of cardiac events using Myocardial Infarction (MI) as an outcome measure, reporting no association and a positive association respectively. This difference in results may be explained by the use of different measures as well as study designs in both studies and because of different limitations with regard to controlling for lifestyle and medical risk factors. This study aims to assess the relationship between the risk of MI and recent exposure to antipsychotic agents by using the self-controlled case series method with which we are able to control for fixed confounders. The results of the self-controlled case series method will be compared to the results of a case-control study using the same data to compare the estimates of both methods.

Determine usefulness of thromboelastography (TEG) as a valuable tool in ex-vivo assessing platelet response to aspirin and clopidogrel (dual) treatment and on-treatment platelet reactivity during acute ST segment elevation myocardial infarction (STEMI) in an acute phase during primary PCI (PPCI) and also during recovery been on maintenance medical therapy and to determine the correlation between platelet response to clopidogrel treatment and the outcome of patients.

We aim to investigate the prognosis of patients diagnosed with AF, particularly in relation to the development of subsequent stroke, heart failure, and myocardial infarction. We will explore the relationship between these outcomes and a range of risk factors.

The number of patients with cardiovascular implantable electronic devices (CIED), including ventricular pacemakers, continues to increase. However, there are no accurate electrocardiographic (ECG) criteria to diagnose acute myocardial infarction (AMI), even if due to acute coronary occlusion (ACO), with a ventricular pacemaker in situ. In this retrospective, multicenter, case-control study the investigators will examine ECG criteria to diagnose ACO in patients with ventricular paced rhythms. During this process, the investigators will also create a database from which investigators will be able to answer multiple additional questions on this population of patients.

The main objective of the GENOCOR project (Genetic mapping for cardiac risk assessment) is the setting up of a joint public/private laboratory (GENOCOR-LAB) dedicated to the development and testing of new cost-effective technologies exploiting the growing knowledge in the genomic correlates of cardiovascular diseases (CVD) and of their evolution; the data obtained by the GENOCOR-Lab should especially orient secondary prevention and specific treatment of ischemic heart diseases (IHD).

The purpose of this study is to determine whether intraoperative hypotension or hypertension is independently associated with postoperative mortality and morbidity whether quality improvement interventions implemented at the University of Michigan and at Washington University: decrease the extent and duration of intraoperative hypotension and hypertension. are associated with decreased postoperative mortality and morbidity.

Thi is an observational, non interventional, cohort analysis by using administrative databases (drugs treatment, laboratory and diagnostic tests, specialist visits and hospitalizations) of Sicilia region to evaluate treatment patterns of patients after Acute Coronary Syndrome (ACS) event.

The hypothesis of the current proposal is that collateral flow is an important determinant of myocardial protection during an ischemic event. Increased collateral flow for any given area at risk will decrease the myocardial damage caused by the occlusion of the infarct related epicardial artery. It is further hypothesized that myocardial salvage provided by collateral flow will decrease infarct size and this in turn will decrease LV dilatation post-myocardial infarction.

The purpose of this study is: To study the clinical usefulness of nurse-performed ultrasound and echocardiographic examinations in a cardiac intensive care unit. To study reproducibility of nurse-performed ultrasound and echocardiographic examinations in a cardiac intensive care unit. To study which ultrasound measure that best correlate with the amount of pleural effusion.
