Active clinical trials for "Infarction"

Type 2 myocardial infarction (MI) is defined as myocardial necrosis that results from an imbalance of myocardial oxygen supply and demand. Although type 2 MI is highly prevalent in patients with critical illness and strongly associated with mortality, the pathophysiology remains poorly understood. Inflammation is central to the development of atherosclerosis, plaque rupture, and other subtypes of MI, but the role of inflammation in type 2 MI and myocardial necrosis has not been defined. The investigators aim to to delineate the mechanistic role of inflammation in myocardial necrosis and type 2 MI complicating critical medical illness.

INTRODUCTION: Sudden cardiac death is one of the most important reasons of death at industrialized countries. Despite its importance, nowadays Clinical Guidelines are not as extended as expected, with respect to indications for primary prevention defibrillator implantation, following MADIT II and MUSTT criteria, especially at Latin American countries. OBJECTIVES: This Project is designed with the purpose of providing tools to help spreading primary prevention by the means of clinical evidence on real risk of death in this group of patients. REGISTRY DESIGN: retrospective (at stage 1); prospective (at stage 2) multi-center (minimum 25-30 centres) international (Argentina, Brazil, Colombia, Chile, Mexico and Venezuela) non randomized. Sample size: at screening about 12.500 patients and 962 patients at treatment stage REGISTRY DEVICES: CE marked (Conformité Européenne) single-chamber, dual-chamber or CRT (Cardiac Resynchronization Therapy) implantable cardiac defibrillator (ICD).

This is a real-world prospective cohort study aiming to generate knowledge about the characteristics, treatments, and outcomes of hospitalized AMI patients in Jilin Province. The study includes hospitalizations diagnosed of AMI, including ST segment-elevation myocardial infarction (STEMI) and non-ST-segment-elevation myocardial infarction (NSTEMI).

The aim of this study is to investigate the potential novel risk factors for acute myocardial infarction. Predictors of poor outcomes will be also evaluated.

Objective: The purpose of this project is to study the post miyocardial infaction (MI) damage and subsequently developed post-infarct cardiac repair process on the basis of cellular, molecular and imaging techniques. Besides this, whole genomesequencing and analysis (GWAS) will be performed to determine common varying genetic loci in order to anticipate whetherthese findings and its related pathways would be the predictors of adverse remodeling after MI or not.

This study will compare the microcirculatory resistance (IMR) of infarct-related artery (IRA) in patients who underwent immediate versus deferred stenting during percutaneous coronary intervention (PCI) for acute myocardial infarction.

Primary aim: evaluation of the short term outcome of different techniques used in bifurcational coronary arteries intervention regarding major adverse cardiac event (MACE): cardiac death, myocardial infarction, target vessel revascularization, or stent thrombosis and occurrence of Unstable angina (UA) with ECG changes and echo findings in the same target vessel in Assiut university Cath. lab. Secondary aim: calculation of the percentage of bifurcational coronary arteries intervention in Assiut University Cath.lab

Coronary atherosclerosis is the leading cause of death worldwide. Diabetes mellitus is associated with increased prevalence of coronary artery disease Increased plasma glucose is a common feature in the acute phase of myocardial infarction, even in patients without diabetes. Patients with stress hyperglycemia, but without previous diagnosis of diabetes, were at increased risk of congestive heart failure, arrhythmia and cardiogenic shock as well as increased both in-hospital and long-term mortality . Previous studies have demonstrated larger infarct size and poorer prognosis inpatients with hyperglycemia upon hospital admission compared with patients without hyperglycemia It has been reported that stress hyperglycemia impairs microvascular circulation and may lead to no-reflow phenomenon. No reflow phenomenon was significantly more frequent among patients with hyperglycemia and increased progressively with increasing admission blood glucose in patients with Acute Myocardial Infarction . Furthermore, patients with high admission glucose are more likely to develop restenosis and require repeat revascularization procedures compared with those with normal admission glucose and are also at increased risk for repeated Myocardial Infarction, stent thrombosis and death.

This study is intended to provide contemporary data on the residual cardiovascular risk in all consecutive patients with acute myocardial infarction, especially in patients who survived stably within one-year after percutaneous coronary intervention. In addition, this study will identify which baseline clinical, angiographic, or treatment factors are associated with residual cardiovascular risk and bleeding events

This prospective observational study will evaluate and compare the sensitivity and specificity of the Modified TIMI, HEART and SACS Scores for accurately predicting the presence and absence of obstructive coronary artery disease (OCAD) as diagnosed during coronary angiography in the cardiac catheterization suite. In addition, we plan to determine if a variant of SACS, HEART, TIMI, or a hybrid score resulting from combining formulas from two or all three scores yields a new tool that exceeds the predictive performance of all three current models for determining the absence or presence of OCAD.
