Active clinical trials for "Myocardial Infarction"

The goal of this study is to identify the risk factors for the occurrence of arrythmia in patient with stemi in prehospital management. We included 652 patients who presenting a STEMI from september 2017 to october 2020 and manage by physician in prehospital and bring to CHU of Dijon. We analyse and compare the caracteristics of a group of STEMI patients who presenting an arrythmia to an other groupe of STEMI patient without arrythmia

The purpose of this study is to develop a risk score to predict the risks of in-hospital major adverse cardiac events in ST-segment elevation myocardial infarction patients treated by primary percutaneous coronary intervention.

Sudden death from ventricular arrhythmia is a serious and common complication of myocardial infarction, especially with low left ventricular ejection fraction (LVEF). Implantable cardiac defibrillator (ICD) implantation is currently recommended at three months of optimal medical treatment in patients who have had a myocardial infarction and have a LVEF below 35%. This strategy indeed allows a reduction in mortality while early post-infarction implantation showed no benefit in terms of survival. However, the risk of sudden death at this period is the greatest and the temporary defibrillator vest, marketed under the name LifeVest, is now indicated in the early post-infarction period in patients with LVEF less than 35%. Indeed, the LifeVest would allow a reduction in sudden death of rhythmic origin in the first three months post-infarction. No study has yet investigated the prognostic significance of a ventricular rhythm disorder (ventricular tachycardia [VT] or ventricular fibrillation [VF]) occurring during this early and short (approximately 3 months) particular period of wearing the LifeVest: is this a random event, or is it an event predictive of a rhythmic recurrence? The aim of the study is to assess the association between the occurrence of a sustained ventricular rhythm disorder in the early post-infarction period, during the period of wearing the LifeVest (ventricular episodes detected, treated or not), and the risk of rhythmic recurrence at 12 months.

The study intends to investigate the alteration of regional myocardial work in patients with acute anterior myocardial infarction underwent primary percutaneous coronary intervention (PCI), and compare the distribution of regional myocardial work in patients with/without early remodeling at acute phase and 3-month follow-up.

The purpose of this study is to asses the prognostic value of lung ultrasound in patients with ST-segment elevation acute myocardial infarction.

This study aims to gather information to what extent patients follow the treatment regimen of low-dose aspirin for primary and secondary prevention of diseases of the heart and blood vessels. Researcher will collect information about the percentage of time a patient has access to the medication, how long patients continue with the medication and of the proportion of patients who switch from dual-antiplatelet therapy (including low-dose aspirin) to a single antiplatelet therapy. The study will make use of secondary healthcare data sources converted in to Observational Medical Outcomes Partnership (OMOP) common data model within the Observational Health Data Sciences and Informatics (OHDSI) network.

Tako Tsubo syndrome (TTS) is characterized by the occurrence in the context of mental or physical stress, a clinical and ECG of acute myocardial infarction without significant coronary artery stenosis, accompanied by a disorder Acute, reversible left ventricular who takes on a characteristic apical ballonnisation evoking the image of a Japanese octopus trap called Tako (octopus) tsubo (jar). Pathophysiology of unknown changes immediate life-threatening prognosis is often good in the longer term.

Introduction: Patients undergoing noncardiac surgery are at increased risk of cardiovascular complications. The development of methods that can accurately predict the occurrence of these events is of critical importance and large studies have been published with this purpose. Based on these studies, several algorithms have been proposed to predict of cardiovascular events postoperatively. However, quantification of this risk is often difficult to measure, especially in those patients with subclinical disease, not always detected in routine evaluation. The ankle brachial index (ABI) has proved a valuable tool in the quantification of cardiovascular risk, and perhaps the most promising when compared with other methods. It is easy, cheap, fast and feasible in office care, with a great acceptance between patients and small intra and inter observer variability. Despite strong evidence of the utility of ABI as a tool in assessing cardiovascular risk, there are no data about the use of ABI in other patients referred for non vascular surgery, which constitutes the majority of operations performed worldwide. Objectives: To evaluate the use of ABI as a predictor of cardiovascular events in patients undergoing non-cardiac and non-vascular surgery and its applicability as a tool in the reclassification of patient risk groups established by guidelines for perioperative evaluation. Methods: 300 moderate to high risk patients referred for non-vascular and non-cardiac will be included. Data about risk factors, signs and symptoms, physical examination and treatment used will be collected before surgery. The ABI will be measured and the patient will be monitored for 30 days to the detection of cardiovascular events: death from any cardiovascular causes, unstable angina, nonfatal myocardial infarction, isolated elevation of troponin, decompensated heart failure, cardiogenic shock, stop nonfatal heart failure, pulmonary edema, stroke and lower limb ischemia. Postoperative electrocardiogram, total creatine kinase, MB fraction and troponin I will be measured daily until 3º day and whenever clinically indicated.

The initial manifestation of symptomatic coronary disease can range from angina (or symptoms of angina), unheralded acute coronary syndrome (ACS), or unheralded coronary death. A better understanding of gender differences in initial presentation of coronary disease and the rate and predictors of progression to subsequent stages in coronary disease could help to identify which gender- specific factors might reduce or slow transition to more serious disease states and improve outcomes. The investigators' research focuses on the role primary care management of cardiovascular risk factors plays in gender differences in the progression to subsequent disease states and to mortality.

Despite a relatively high prevalence of non-atherosclerotic coronary artery disease (NACAD) among young women, the majority of these abnormalities were misdiagnosed in this population, and thus treatments were not targeted adequately in this patient population. Furthermore, the short and long-term cardiovascular outcomes of young women with NACAD have not been evaluated. Given the importance of NACAD in young women, the challenges of diagnosis and subsequent treatment, and unknown outcomes with NACAD, we propose a prospective registry to further evaluate this population. We propose to evaluate young women (age < or equal to 55) presenting with myocardial infarction (MI) prospectively, to diagnose the etiology of MI differentiating atherosclerotic versus NACAD, to correlate the prevalence of FMD in other vascular territory, and to evaluate the long-term outcome of young women with NACAD in comparison to those with atherosclerotic CAD over a 5-year follow-up.
