Active clinical trials for "Myocardial Infarction"

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.

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.

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

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

The main objectives of this study are: i) to investigate the incidence and prevalence of fatal and non-fatal heart failure (HF) following myocardial infarction (MI) and its evolution over time in men and in women; ii) to identify prognostic factors for developing HF in patients who had an MI.

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.

The purpose of this study is to characterize the plaque morphology in patients with acute STEMI by OCT after aspiration thrombectomy.

Cohort study aimed at evaluating the incidence of left ventricular (LV) dysfunction after myocardial infraction (MI) and assessing the prognostic utility of change in ejection fraction (EF) over the initial 12 months after MI.

The purpose of this study is to assess the impact of frailty as a multidimensional risk factor on the outcomes of adult cardiac and vascular surgery. For the purpose of defining patient frailty a multimodal questionnaire has been developed including measurement of psychological, socioeconomical, neurological and behavioral aspects. This study also features an investigation of the possible relationship between sudden regional weather changes, individual meteorological susceptibility of the patients and the outcomes of adult cardiac and vascular surgery.

Despite modern reperfusion strategies, myocardial infarction leads to deleterious processes resulting in left ventricular remodelling (LVR) and heart failure (HF). Several biomarkers i.e. galectin-3 (Gal-3) and soluble ST-2 protein are involved in LVR as a result of inflammatory processes and fibrosis. There is an evidence of a high prognostic value of both biomarkers in prediction of outcomes in HF patients. This study will further investigate the role of Gal-3 and ST-2 in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) and without prior HF in prediction of unfavourable outcomes.
