Filter by:Introduction: Secondary prevention after acute myocardial infarction may include cardiac rehabilitation and lifestyle changes. Cardiac rehabilitation has mainly taken place in hospitals without coordination with primary healthcare. Motivational interviews have been shown to be effective as a means for change in patients after acute myocardial infarction. The objective of this study is to evaluate the effectiveness of a cardiac rehabilitation program with motivational interviews in patients discharged from hospital after acute myocardial infarction. Methods: Randomized clinical non-pharmacological trial. A minimum sample of 284 participants requiring cardiac rehabilitation after acute myocardial infarction in six primary healthcare centers. Participants will be randomized to cardiac rehabilitation with motivational interviews or normal standard of care. All secondary results will be evaluated at 1,3 and 6 months.
Despite the advances of pharmacologic and interventional therapies, sudden (or arrhythmic) cardiac death remains very high in the early weeks-to-months after an acute myocardial infarction (MI).The majority of cardiac arrests occur in patients who have large infarctions resulting in extensive myocardial damage, which is translated into lower left ventricular ejection fraction (LVEF). Hence, low LVEF remains -to the current time- the most robust predictor for post MI sudden (and presumably arrhythmic) death; and is the determinant for implantable cardioverter defibrillator (ICD) candidacy for primary prevention as per clinical practice guidelines.ICD significantly and effectively reduced ventricular arrhythmia (VA)-mediated cardiac deaths among these patients.
A cross-sectional real-world data study designed to assess the use of statins in individuals assisted within the primary care system in Brazil.
The primary objective of this study is to evaluate the effectiveness of early treatment with evolocumab plus routine lipid management vs routine lipid management alone when administered in the acute setting to reduce myocardial infarction, ischemic stroke, arterial revascularization, and all-cause death in subjects hospitalized for an acute myocardial infarction (non-ST-segment elevation myocardial infarction [NSTEMI] and ST-segment elevation myocardial infarction [STEMI]).
To compare clinical outcomes of myocardial infarction with non-obstructive coronary arteries (MINOCA) according to the coronary microvascular dysfunction (CMD), evaluated by optical coherence tomography (OCT), invasive and non-invasive coronary physiologic assessment.
The REDUCE-IT Canada SA Study is a cross-sectional study aiming to determine the proportion of study participants who meet the Health Canada-approved indication for icosapent ethyl (IPE;Vascepa®).
Aim: To develop and field test an Integrative Cardiac Rehabilitation Employing Smartphone Technology (I-CREST) system, and evaluate its effects on CR utilization, cardiac self-efficacy, functional capacity, health-related quality of life (HRQoL), anxiety, depression, medication adherence, cardiac risk factor control and clinical outcomes among post-myocardial patients in Singapore. Background: Centre-based cardiac rehabilitation (CBCR) participation rates among eligible patients remain low at 10-30% worldwide and less than 10% in Singapore, reportedly due to long-standing challenges surrounding accessibility, conflicting commitments, low socioeconomic status, and costs. A recent challenge is the COVID-19 pandemic, that resulted in the partial or complete closures of CBCR programmes Alternative strategies to deliver cardiac rehabilitation using novel technologies are needed to increase participation rates and improve health outcomes. Design: A single-blinded two-arm randomised controlled trial (RCT) will be adopted. Methodology: The is a two-phase study. Phase one involves the development and field-testing of the I-CREST system. The I-CREST system comprises of a smartphone application, a wearable heart rate monitor and a web-portal. Phase two is a single-blinded two-arm RCT with repeated measures. 124 participants will be recruited from the National University Hospital in Singapore and will be randomly allocated to intervention or control group. Participants in the intervention group will receive the 6-week I-CREST intervention - including the newly developed I-CREST system, one face-to-face training session, and weekly telephone calls. The participants in the control group will receive the 4-week traditional CBCR. Data will be collected at baseline, at 6 weeks (after completion of the CR programme), at 3months and at 6months from baseline. Sociodemographic and clinical data will also be collected. A cost-effectiveness analysis will also be performed to evaluate the feasibility of I-CREST compared to the CBCR platform. To assess the participants' experiences of the I-CREST system, a process evaluation will be undertaken at the conclusion of the study. Significance. This study will generate insights into the suitability and effectiveness of I-CREST as an alternative to traditional CBCR outpatient services.
The study will use 18F-PBR06/uExplorer to study the activation of macrophages and systemic perfusion in patients with ST-segment elevation myocardial infarction (STEMI) or stable angina (SA). Participants will receive the total-body PET/CT scan on the seventh day (Day 7, D7) and D180 of enrolment.
This protocol describes a retrospective, single-center study intended to test the impact of optical coherence tomography(OCT) on long term clincical outcomes in patients with acute myocardial infarction(AMI). All the patients will be followed by intracoronary OCT at medium follow-up of 3 years.
Rationale: Heart attacks are a major cause of death and result from coronary blood clots that require acute coronary intervention and antithrombotic drugs to restore blood flow and prevent new heart attacks. Over time, more potent antithrombotic drugs have been introduced like prasugrel and ticagrelor. These drugs have replaced the older drug, clopidogrel, as approximately 30% of patients are low-responders to clopidogrel for genetic reasons. However, the newer drugs introduce a significant risk of serious bleeding. Aim: The aim of this trial is to assess a reduced antithrombotic strategy for high bleeding risk patients with heart attacks to reduce bleeding safely. Hypothesis: Significantly reduced bleeding with a similar preventive effect are expected. Design: The Dan-DAPT trial include high bleeding risk patients with heart attacks from Danish hospitals (Rigshospitalet, Aarhus, Odense, Aalborg, Roskilde, and Gentofte hospital) and randomize them to standard-of-care or shorter and individualized antithrombotic therapy based on responsiveness to clopidogrel after genetic testing.
