Active clinical trials for "Myocardial Infarction"

This is a multicentre observational study planned to gather follow up data for a period of 1 year in order to understand the treatments and outcomes of ST-segment elevation myocardial infarction(STEMI) and improve medical care quality in Fujian province for China. Consecutive patients who were admitted and diagnosed with STEMI between January 2014 December 2018 were conducted at five regional representative hospitals in Fujian province, which included the Fujian Provincial Hospital,Longyan First Hospital, the affiliated hospital of putian university,the Second Affiliated Hospital of Fujian Medical University and Mindong Hospital of Ningde City.

The investigator aims to determine the feasibility of understanding the process of active versus chronic calcification using Na-F PET scan and contrast CT scan of the heart. The patient cohort will consist of patients diagnosed to have either acute coronary syndrome (ACS) (comprising of either unstable angina pectoris or acute myocardial infarction) or suspected coronary artery disease (CAD). The PET images will be compared to images obtained from standard contrast CT of the coronaries. This study will provide additional insights about active versus non-active calcification amongst patients with ACS or suspected CAD.

The investigators intend to evaluate Oxidative Stress biomarkers through a. Catalase Activity Assay; b. Lipid Peroxidation Assay; c. SOD Assay; d. Total Antioxidant Capacity Assay; e. Glutathione Peroxidase at patients with acute myocardial infarction STEMI referred for primary PCI; The investigators also aim to evaluate cardiac necrosis by measuring Heart Fatty Acid Binding Protein (H-FABP), TnI, CK, CK-MB, LDH and AST in these patients with acute myocardial infarction referred for primary PCI; Also, the investigators intend to evaluate body composition through bioimpedance spectroscopy (BCM - Fresenius Care) at the moment of admission. The investigators aim to fully characterise these patients through oxidative millieu, hFABP and make correlations with LVEF dysfunction.

Recently, the use of preoperative BNP as a preoperative risk stratifcation tool was added to the Canadian Cardiovascular Society (CCS) guidelines (4) on perioperative cardiac risk assessment and management for patients who undergo noncardiac surgery, based on the prognostic value of preoperative BNP in indentifiy patients at significant risk of 30-day mortality, nonfatal myocardial infarction, or myocardial injury after noncardiac surgery (MINS). While the value of screening for high risk patients through the use of preoperative BNP been demonstrated, the management of postoperative ischemia is less clear. Therefore, this study aims to: Evaluation of the use of BNP as a preoperative screening biomarker; how often is it ordered in Anesthesia Preadmission Clinic and what is the incidence of a positive result (BNP ≥ 92 ng/L) Determine the incidence of myocardial injury after non-cardiac surgery (MINS) at 30 days and myocardial infarction at 1 year at a tertiary care center when BNP is used as a screening tool Record patterns of management of patients with MINS Determine the cost associated with the different patterns of management of MINS Comparison with a cohort group who qualified for BNP screening according to CCS guidelines but did not have it measured. The investigators will attempt to evaluate the cohort group for MINS at 30 days and myocardial infarction at 1 year.

This is a nationwide cohort study on real-world patients (n≈30,000) surviving a first myocardial infarction (MI) 2006-2013 and alive to attend a routine 1-year follow-up. Associations between Socioeconomic Status (SES) and secondary preventive actions (SPAs) throughout the first year is studied and assessed as possible mechanisms underlying the increased risk of a first recurrent hard cardiocvascular (CV) outcome, recurrent atherosclerotic cardiovascular disease (rASCVD), in patients with low Socioeconomic Status during long-term follow-up (2006-2018).

The investigators have created a new risk score that predicts whether initially stable patients with myocardial infarctions (heart attacks) will require intensive care while they are in the hospital. To evaluate how well this risk score works, the investigators plan to calculate this risk score for every patient that comes to the hospital with a heart attack, provide the risk score to the emergency room doctor treating the patient, and determine whether each patient required intensive care while they were in the hospital. The investigators will then evaluate whether giving emergency room doctors access to this risk score reduced costs of taking care of heart attack patients compared with previous years.

A total of 50 participants diagnosed with ACS (group A ticagrelor 180mg/d, n=25), group B (clopidogrel 75mg + rivaroxaban 5mg/ d, n=25)) were consecutively enrolled and treated with study drugs on top of aspirin (100mg/d) for 1 month. VerifyNow® and Global thrombosis test were performed at day 2 and 1 month after administration of study drugs. The investigators compared aspirin reaction unit (ARU) and P2Y12 reaction unit (PRU), occlusion time (OT) which reflects shear stress-induced thrombotic activity, and lysis time (LT) which showed endogenous lytic activity between the two strategies at both time points.

To analyze the relationship between the clinical data and the outcomes of STEMI patients.

A multi-center, prospective, consecutive enrolled, observational registry. The population being studied includes all patients undergoing treatment of "de novo" lesions in native coronary vessels, saphenous vein graft and/or arterial bypass conduits with the COBRA PzF coronary stent system. The registry will primarily assess the rate of MACE (cardiac death, myocardial infarction and clinically driven target lesion revascularization.

All patients in Iceland with STEMI (2008-2018) and NSTEMI (2013-2018) that underwent coronary angiography and had obstructive coronary artery disease were included. Information about patients and angiography results and treatment were obtained from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Survival was estimated with Kaplan-Meier method. Cox regression analysis were used to identify significant risk factors for long-term mortality. Relative survival was defined as observed survival divided by expected survival of the population of Iceland
