Active clinical trials for "Myocardial Infarction"

Coronary flow reserve is an important measure of the integrity of the coronary microcirculation. Moreover, impaired coronary flow reserve is a predictor of future cardiovascular events and poor prognosis in patients after acute myocardial infarction. After acute myocardial infarction, coronary flow reserve remains significantly reduced. A previous randomized, double-blind Placebo-controlled trial (REPAIR-AMI) demonstrated complete normalization of coronary flow reserve after intracoronary application of autologous bone marrow-derived progenitor cells (but no effect in the placebo group) in patients with ST segment elevation myocardial infarction. The current study is planned to extend these findings to patients with Non-ST segment elevation myocardial infarction, since these patients have an equally reduced outcome.

The trial has the following primary objective: To compare the safety and effectiveness of primary acute MI intervention with ABT 578-eluting balloon expandable stent (Medtronic, Minneapolis, MN) vs. sirolimus-eluting balloon expandable stent (Cordis Johnson & Johnson, Warren, New Jersey) vs. paclitaxel-eluting stent (Taxus Liberte, Boston Scientific).

Study to assess the efficacy of intramyocardial bone marrow derived mononuclear cell therapy concerning left ventricular ejection fraction as measured by echocardiography.

The purpose of this study is to determine cell therapy efficacy in patients with ST elevation acute myocardial infarction (STEMI)

Drug eluting stents (DES) are widely used for treatment of coronary artery lesions. The Xience Sierra stent has a refined design of the metal stent backbone and is used in patients with various clinical syndromes and in different lesions. Clinical outcome of patients with previously unknown (silent) diabetes and prediabetes is of increasing interest since the latter group has recently shown to be associated with a significant risk of adverse cardiovascular events after treatment with contemporary DES. Outcome data in a population of high-risk all-comer patients, including many patients with diabetes mellitus and prediabetes, would be of great interest, but such data are not available yet. In addition, there is a lack of data in a general all-comer population. Therefore, the COASTLINE study will primarily assess the safety and efficacy of the Xience Sierra stent in a general all-comer population as well as a high-risk all-comer population.

Based on the clinical data of patients, a machine learning model for coronary heart disease diagnosis was established to evaluate whether the model could improve the accuracy of coronary heart disease diagnosis, and to evaluate its authenticity, reliability and benefits.

Examine the analytical and clinical performance of Atellica IM TnIH assay for the diagnosis and rule out of acute myocardial injury and myocardial infarction in patients presenting to the emergency department in whom serial cTnI measurements are obtained on clinical indication.

Compare the analytical and clinical performance of hs-cTnI and hs-cTnT assays for the diagnosis of acute myocardial injury and myocardial infarction in patients presenting to the emergency department in whom serial cTnI measurements are obtained on clinical indication.

Study objective is the evaluation of safety and efficacy at 12 months of the combination treatment of bare metal Stent plus Paclitaxel Eluting Balloon vs drug eluting stent in patients with ST-elevation myocardial infarction with less than 12 hours of evolution.

The Mindray High Sensitivity Troponin-I Measurement System is an in vitro diagnostic test for the quantitative determination of high sensitivity cardiac troponin I (hs-cTnI) in human serum or plasma. The Mindray High Sensitivity Troponin-I Measurement System is to be used as an aid in the diagnosis and rule out of acute myocardial infarction (AMI).
