Active clinical trials for "Infarction"

Erectile dysfunction is a common sexual problem affecting up to one-third of men throughout their life. It is now well recognized that risk factors for erectile dysfunction (ED) include the same risk factors as coronary artery disease, including smoking, dyslipidemia, diabetes, hypertension, lack of physical activity and obesity. We will investigate the effect of reperfusion strategies (primary angioplasty & therapeutic therapy) on the prevalence of erectile dysfunction after acute myocardial infarction. Erectile function will be evaluated using the international index of erectile function after 3 months of successful reperfusion treatment of acute myocardial infarction.

Recurrent myocardial infarctions (reinfarctions) can be due to recurrence at the original treatment site, the presence of untreated lesions elsewhere, or in progressive lesions. There are scarce published data describing the localization (affected vessel/s) and severity (NSTE-ACS/STE-ACS) of reinfarction(s) compared to the index MI (e.g proportion of recurrent infarctions in the previously diseased vessel) in large unselected patient populations. If reinfarctions are generally more severe than index MI/recurrent MI(s), this might have implications for choice of treatment and treatment length. Moreover, data from unselected patient populations on the overall incidence pattern/rate of patients experiencing multiple reinfarctions is sparse. Patients who experience multiple ischemic events may be a subset of patients who are poor responders to therapy. There is also a possibility that patients with multiple events are less likely to have received evidence-based therapy such as coronary stenting, novel and more effective antithrombotics and modern lipid lowering treatment for the initial event. Poor adherence to secondary prevention measures (e.g. low compliance to medication and adherence to cardiac rehabilitation programs) may also increase the risk of recurrent events. Therefore identification of the baseline characteristics, including treatment decision strategies in the setting of a myocardial infarction, among such subjects may allow modifications of the clinical management strategy prior to the occurrence of subsequent ischemic events. Such modifications could include providing a more intensive or additional therapy in certain patient groups or find strategies to improve patient adherence and drug compliance. A patient with reinfarctions requires more hospitalizations, treatments, laboratory tests, and out-patient visits, resulting in overall increased costs. From the patient perspective, recurrent events result in higher mortality and worsened quality of life.

Reliability of 3D angio QFR functional evaluation of all non culprit lesions >50% in STEMI patients during first acute procedure

Immediate potent inhibition of platelet function is critical for the prevention of periprocedural ischemic event occurrences in high risk N-ST segment elevation myocardial infarction (NSTEMI) in patients undergoing percutaneous coronary intervention (PCI). Currently, dual antiplatelet therapy with aspirin and an oral P2Y12 receptor blocker (with loading doses) is widely used for PCI. However, immediate, potent and reversible inhibition of platelet aggregation is not possible even with the newer oral agents, prasugrel and ticagrelor. Therefore, an intravenously administered GPIIb/IIIa receptor inhibitor (tirofiban) or P2Y12 receptor blocker (cangrelor) with fast onset and offset of actions will provide more desired antiplatelet effects in the setting of PCI. This study will measure and compare the anti-platelet effects of Tirofiban and Cangrelor in patients presenting with N-STEMI and undergoing PCI.

Cost effectiveness between PPCI and thrombolytic therapy in STEMI patients without contraindications

Acute myocardial infarction (AMI) usually occurs suddenly and is associated with considerably high mortality rate. The infarct-related artery in inferior wall AMI is usually located at right coronary artery (RCA), less often at left circumflex coronary artery (LCX). Inferior wall AMI occlusive site before the first right ventricular branch of RCA was more frequently associated with right ventricular infarction, which had higher incidence of bradyarrhythmia, shock, and in-hospital death. Early recognition of the site of infarct-related artery especially combination with right ventricular infarction and respond promptly may result in a significant reduction in in-hospital mortality and morbidity. There were several non-invasive methods to predict the culprit site, which including: radioneuclear imaging study, echocardiography or electrocardiogram. Among these methods, electrocardiogram is one of the most simple and convenient tool. Several algorisms have investigated but these algorisms included using leads III, II, I, aVL, V1, V2, V3, V5 and V6, which can only differentiate RCA and LCX lesions but cannot assure whether the culprit site is located at proximal or distal RCA. Thus, the aim of this study is designing a method which is simple and useful in identifying the culprit sites in inferior wall acute myocardial infarction (AMI). According to the medical record, patients with inferior wall AMI who have no previous history of MI (or the first AMI attack) will be enrolled. These patients are divided into 3 groups from coronary angiography, depending upon the culprit lesion (1) before (proximal) or (2) after (distal) the right ventricular branch of RCA and (3) LCX. A two-step study strategy will be performed to analyze which electrocardiographic variables are capable of discriminating the culprit site of coronary artery. Using the area under the receiver operating characteristic (ROC) curve analysis, we plan to determine which one of the above variables is the most powerful criterion in discriminating the culprit site of coronary artery. Due to the fact that the case number of the first inferior AMI will be limited, this study will be carried out at 3 hospitals in order to collect more cases with the coming year.

The purpose of this study is to evaluate the predicting role of plasma GLP1 level on major adverse cardiovascular events (MACE) in patients with acute myocardial infarction who undergo percutaneous coronary intervention.

Comparison of high PD1+ T cell and low PD1+ T cell expression in peripheral blood for cardiac function prognosis in Patients with acute myocardial infarction

Adiponectin (Ad) is an abundant protein in human body, and reports have shown that it act as a novel risk factor for brain and heart ischemia injury. This 5 years follow-up study will focus on serum adiponectin concentration, activity and isoforms in Chinese population and its correlation to these diseases.
