Revascularization strategies for ST elevation myocardial infarction (STEMI) study (ASSIST-CMR) will compare the effects of two revascularization strategies [same sitting multivessel primary PCI (SS-PCI) and culprit vessel only primary PCI (IRA-PCI)] on myocardial infarct size (MIS) as determined by cardiac magnetic resonance (CMR) imaging in patients presenting with STEMI and multivessel disease (MVD).
To investigate the causes of hospital variation in outcomes from acute coronary syndromes in England and develop recommendations for improving patient care.
The goals of this study are two fold: 1) To learn whether a personalized patient health goal and reminder tool helps patients to learn more about their condition and to make changes in behavior and medication taking to reduce the risk of another heart attack. 2) To examine a blood sample to learn how patients are responding to their medications. The study team will enroll approximately 220 patients in the hospital recovering from a heart attack. Half of the patients will receive the educational tools and a copy will be sent to their outpatient provider.
Cardiovascular disease (CVD) is an important public health problem that affects millions of people worldwide. Associations between risk factors, such as smoking, dyslipidaemia or hypertension, and prevalent CVD are well documented. However, few studies have investigated associations with onset of disease. The initial manifestation of CVD, for example an episode of unstable angina, is important because it influences the prognosis, the quality of life and the management of disease. Furthermore, the extent to which social deprivation, alcohol consumption or atrial fibrillation affects presentation of CVD is poorly understood and deserves further consideration. Most previous studies have considered CVD as a single entity. However, differences in aetiology between coronary phenotypes suggest that risk factors may not be shared across specific coronary phenotypes and their relative importance is likely to differ for each phenotype. Gaining knowledge of these differences could provide insights into the pathophysiology of specific forms of CVD and could eventually lead to modification of recommendations for patient management and disease prevention. We propose to use the linkage of the national registry of coronary events to general practice records in the Clinical Practice Research Database (CPRD), to investigate whether demographic, behavioral, and clinico-metabolic risk factors differentially influence the onset of specific types of CVD.
This was a double-blind, randomized, placebo-controlled study that was designed to enroll a total of 225 participants with de novo anterior wall acute ST-segment elevation myocardial infarction (STEMI) due to a lesion of the left anterior descending coronary artery undergoing percutaneous coronary intervention (PCI). Eligible participants were to be enrolled and undergo revascularization of the culprit left anterior descending (LAD) coronary artery. The interventional procedure included as dose ranging assessment of intracoronary (IC) delivery of MPC or placebo infused into the stented coronary artery. This study compared two doses of MPCs and a placebo control group. Study participants were randomly assigned in 1:1:1 fashion to receive either 12.5 Million or 25 Million MPCs or placebo (saline). Initially, each group was designed to have approximately 75 patients per treatment group. The Primary Objective of the study was to determine the safety and feasibility of IC infusion of investigational MPCs in this acute STEMI population. The Primary Objective of the study was to determine the safety and feasibility of IC infusion of investigational MPCs in this acute STEMI population. Feasibility of the infusion of the investigational agent was assessed by measurement of thrombolysis in myocardial infarction (TIMI) flow and perfusion (1) immediately prior to, (2) during (after approximately 50% of total investigational agent volume infused) and (3) following the investigational agent infusion after successful PCI and stenting. There was no evidence of clinically important coronary microvascular obstruction related to infusion of the investigational agent.
The investigators will test the hypothesis that transcutaneous electrical nerve stimulation (TENS) may attenuate peripheral vasoconstriction and to improve blood flow redistribution during handgrip exercise in acute myocardial infarction (AMI) patients after Coronary Arterial Bypass Graft Surgery (CABG).
Myocardial infarction (MI) outcomes strictly depend on the time to reponed the infarct-related coronary artery. Networks have been activated in the last years in many countries to achieve fast track access of patients with ST-elevation MI to hospital with h24 primary PCI availability or directly to Cath Labs. From 2011 a regional STEMI network have been formally activated in Piedmont. The aim of our registry is to monitor the activity of the STEMI network in the large suburban area of Novara (population of about 800.000 subjects).
SILVER-AMI is a research study of older persons who are admitted to the hospital with a heart attack. Patients will be interviewed in the hospital and again 6 months later. The researchers will also collect detailed medical record information to understand the effect of heart attacks on older persons. The research team at Yale University will use this information to develop a risk model that can be used to help doctors predict recovery. The goal of the study is to help older people in the future make well-informed decisions about their health care during a heart attack.
The purpose of this study is to test the hypothesis that the intracoronary transplantation of autologous mononuclear and CD 133 + bone marrow cells will improve left ventricular contractile function and will reduce the combined end points after the primary STEMI (mortality, recurrent myocardial infarction, angina, heart failure, stroke).
