Filter by:East Asian patients will be required optimal dose of newer P2Y12 inhibitor (ticagrelor) to determine the safer treatment and better outcome. Whether low dose of ticagrelorI is more adequate for clinical practice in Korea is unclear. Therefore, the investigators aim to evaluate efficacy and safety of low dose of ticagrelor in Acute Myocardial Infarction (AMI) undergoing percutaneous coronary intervention(PCI).
Patients with heart attack or heart injury are tested (angiogram) for blockages in their arteries. Many patients develop heart problems caused by damage to small (microvascular) blood vessels. These issues are also relevant to patients with coronarvirus-19 disease (COVID-19). Eplerenone reduces blood vessel injury and is used to treat heart failure. Aim: to test the use of eplerenone in patients with heart attack/heart injury who have small vessel disease, including patients with COVID-19 Patients referred to the Golden Jubilee hospital with a suspected heart attack heart / injury will be invited to participate into a registry-based clinical trial. Screening, enrolment and verbal, informed consent will be obtained during the angiogram then written consent on the ward. Small vessel disease will be assessed using a 'diagnostic' guidewire during the standard angiogram. People with small vessel problems will be allocated to a clinical trial of usual care or eplerenone. Coronary microvascular dysfunction is defined as an index of microvascular resistance ≥25. Coronary flow reserve (CFR abnormal <2.0) and resistance reserve ratio (RRR abnormal <2.0), measured simultaneously with IMR, are predefined parameters of interest. Patients will be allocated into one of the 3 groups: - Group 1: Patients without coronary microvascular dysfunction. No eplerenone - Group 2: Patient with coronary microvascular dysfunction. Usual care, no eplerenone. - Group 3: Small vessels abnormal. Eplerenone tablets. The primary outcome for the trial will be reduced heart injury (biomarkers) in patients with microvascular disease. We will also test heart function (MRI scan) at enrolment and at six months. All patients (Groups 1, 2 and 3) will have an angiogram. Standard blood tests will be collected during the hospital stay, and then again at 1 and 6 months. Other outcomes include questionnaires (health status). We will gather information on longer-term health outcomes (hospitalisation, death) using confidential electronic record linkage. We will ask for permission to store blood samples for future research. The research will improve scientific knowledge about eplerenone therapy in this patient group. The study will create a repository of clinical samples and images which will provide vital data for studies of COVID-19.
Cardiovascular Disease (CVD) is one of the greatest causes of mortality and morbidity globally, particularly in middle to high income countries. In the UK alone, it was accountable for 124,641 deaths in 2017. Further to this, CVD contributes to a vast economic burden, costing the National Health Service (NHS) £19billion annually. This is mainly due to a significant number of hospital readmissions following a first cardiac event (198,000 per annum). Following a cardiac event, an individual is therefore recommended to reduce their risk factors, including lipid profile, smoking status and physical inactivity, to reduce their risk of a secondary event. In healthy individuals, regularly breaking up sitting time reduces cardiometabolic risk markers. The aim of this study is to therefore observe if this effect is replicated in the cardiac population and thus whether breaking up sitting time will reduce the risk of a secondary cardiac event. Potential participants will be required to meet an inclusion criteria to take part in the study: aged 50 years or above and had a myocardial infarction within the past three months at the time of recruitment to the study. Participants will be randomised to each condition: 1) uninterrupted sitting; 2) sitting with intermittent standing and 3) sitting with intermittent light physical activity (stepping to a metronome beat). A number of physiological markers will be measured before, during and after each condition and analysed to compare the effectiveness of each condition. All measurements will be taken at the University of Bedfordshire Sport and Exercise Science Laboratories.
This large real-world international prospective registry will provide a unique opportunity to comprehensively understand the contemporary management, clinical course and short as well as long-term outcomes of all Cardiogenic Shock (CS) patients cared for at four high volume dedicated shock care centers. As the first true North American multicenter CS collaborative with a uniform dedicated and comprehensive case report form, the high patient volumes and wide spectrum of clinical acuity seen at these institutions will provide valuable insight into the factors associated with adverse outcomes; and will serve as a blueprint for future clinical trial designs that may better inform clinical practice.
Prediabetes is associated to an increased risk of cardiovascular disease and mortality. Although metformin can delay progression to diabetes there is a lack of RCTs evaluating the effect of metformin on cardiovascular outcomes. MIMET aims to investigate if addition of metformin to standard care has effects on the occurrence of cardiovascular events after acute myocardial infarction in patients with newly detected prediabetes (identified by oral glucose tolerance test, HbA1c or fasting glucose levels).
Patients who have a heart attack are at high risk for future development of heart failure ('weakening of the heart'). The researchers believe that the reaction of the heart muscle to injury (inflammation) during a heart attack may be contributing to the risk of heart failure. The current study will test the ability of an anti-inflammatory medicine (anakinra) to block the inflammation in the body during and after a heart attack.
Rationale: Pump failure due to acute myocardial infarction (AMI) can lead to cardiogenic shock (CS): a state of low blood flow to end-organs with subsequent multi-organ failure that is associated with high mortality rated. The first line pharmacologic treatment strategy in CS is noradrenaline. This vasopressor drug is used to maintain adequate blood pressures. The assumption is that a mean arterial blood pressure (MAP) ≥ 65 mmHg will improve flow and thereby tissue perfusion of myocardium and other tissues (e.g. renal). However, there is no evidence that an increase in MAP, if achieved by noradrenaline, leads to greater end-organ blood flow and better outcomes. Objective: With this study the investigators aim to investigate the (cost-)effectiveness of reduced noradrenaline in patients with CS by using a lower MAP target of ≥ 55 mmHg, compared to ≥ 65 mmHg. The investigators hypothesize that reduced use of noradrenaline will improve overall survival and decrease renal failure requiring renal replacement therapy. Study design: Open label, randomized controlled multicenter trial Study population: Adults patients with CS due to AMI Intervention: Treatment strategy of reduced noradrenaline, by using a lower MAP target ( ≥ 55 mmHg). Main study endpoint: composite of all-cause mortality and severe renal failure leading to renal replacement therapy within 30-days after randomization.

The purpose of this study is to evaluate whether late recanalization in patients with ST elevation myocardial infarction (STEMI) without Viability on Cardiovascular Magnetic Resonance Image (MRI) can reduce the reverse remodeling through the reduction of the End Systolic Volume (ESV) at 6 months.
There are two types of acute coronary syndrome (ACS): ACS with persistent ST segment elevation (ACS ST +) and ACS without ST segment elevation (non-ST + ACS). The incidence of non-ST + ACS is increasing and currently accounts for the majority of myocardial infarction (MI) hospitalizations, while that of ST + ACS is declining. Complications of MI, which include rhythm and conduction disturbances, are mainly associated with ACS ST +. It is recognized that these complications can occur during non-ST + ACS, but with less frequency. This frequency is not clearly established, and has been the subject of few studies. Recent studies in this direction suggest that the frequency of rhythmic complications is low during non-ST + ACS. However, the data collected concerns inter-hospital transport. The aim of the study is to estimate the frequency of occurrence of potentially fatal rhythmic complications in patients admitted to the emergency room and to the cardiology department for non-ST + ACS.
