Filter by:This is a single-center retrospective observational study in which we consecutively selected patients diagnosed with acute myocardial infarction from September 2019 to March 2024 at the Affiliated Hospital of Xuzhou Medical University. Inclusion criteria: 1. CMR was completed during all hospitalizations; 2. complete clinical data; 3. received continuous cardiac monitoring during hospitalization. Exclusion criteria: 1. unclear or non-compliant CMR images; 2. previous history of myocardial infarction; 3. malignant tumors diseases. Dedicated cardiovascular imaging software CVI42 (cvi42® version 5.13.5, Circle Cardiovascular Imaging, Canada) was used for image analysis. LA strain was obtained by cardiac MRI feature tracking. Patient prognosis was obtained through chart notes and telephone follow-up. Major events included atrial fibrillation, ischemic stroke, and all-cause mortality.
The goal of this observational study is to define the incidence of heart failure (HF) after acute coronary syndrome (ACS). The main question it aims to answer is: • To define HF incidence in the medium and long-term in the context of public healthcare coverage ensuring universal access to early coronary revascularization after ACS and extended neurohormonal treatment. Analyses will cover the entire population of Catalonia (North-Eastern region of Spain, N = 7.860.563 in 2020). Researchers will compare HF incidence rate according to relevant subgroup characteristics including event type, age groups or sex, inter alia.
Cardiac-enriched micro-RNAs (miRNAs), micro RNA 208b and 133a(MiR-208b, MiR-133a)) corresponds to the health and disorders of the cardiovascular system. An intron of the cardiac myosin heavy chain gene MYH7 encodes miR-208b. It is found on chromosome 14 in humans. Identify new diagnostic biomarkers based on miRNAs, researchers examine the expression of miR-133a and 208b at various time points (04 hours, 08 hours, 12 hours, 24 hours, 48 hours) following the development of the infarct and compared it to the traditional myocardial infarction biomarkers cardiac troponine (cTnl) and Creatine kinase-MB (CK-MB).
This is a randomized controlled trial (RCT) to test a novel artificial intelligence (AI)-enabled electrocardiogram (ECG)-based supporting tool for improving the diagnosis and management of ST-elevation myocardial infarction.
The aim of the study is to evaluate whether providing a targeted heart health education campaign to regions at high risk of heart attacks will improve ACS patient's symptom recognition and response. The intervention will be will be evaluated according to a cluster randomized, stepped wedged design. The clusters are eight local government areas (LGAs) in Victoria, Australia. The main primary outcome will be assessed in consecutive patients presenting to emergency departments from the six LGAs throughout the study period with an ED diagnoses of acute coronary syndrome.
The aim of this study is to examine the effect of secondary prevention education given to individuals after acute myocardial infarction on physiological parameters, anxiety and quality of life.
The concentration of troponins in plasma is used for diagnosing acute myocardial infarction. Different types of heart-specific troponins can be measured and with different analytical methods. The primary aim of this study is to evaluate the diagnostic characteristics of a new analytical method for measuring troponin I in diagnosing acute myocardial infarction.
For patients presenting with ST-elevation myocardial infarction (STEMI), immediate and timely reperfusion treatment is essential. Pharmacoinvasive strategy (PIs) exploits the widespread availability of fibrinolysis and its early administration to restore some degree of myocardial blood flow, coupled with the complete restoration of the culprit coronary artery patency that can be obtained with subsequent angioplasty. Several trials have demonstrated the efficacy and safety of PIs when compared with PPCI; however, real-world data is lacking, especially in developing countries. The aim of this study was to compare safety and efficacy of PIs with PPCI in real-world patients with STEMI presenting to large geographical area.
Myocardial injury is common in patients without acute coronary syndrome, and therefore international guidelines propose a classification of patients with myocardial infarction by aetiology. This differentiates between myocardial infarction due to plaque rupture (type 1) and myocardial oxygen supply-demand imbalance (type 2) in other acute illnesses. However, these guidelines have not been widely adopted as the diagnostic criteria for type 2 myocardial infarction are not clearly defined. Patients with type 2 myocardial infarction have poor long term outcomes, with at least twice the mortality at five years compared to those with an index type 1 myocardial infarction. Despite the majority of deaths being attributable to non-cardiovascular events, the rate of future type 1 myocardial infarction or cardiovascular death is similar regardless of index classification. If this future risk is related to the presence of underlying coronary artery disease, then there may be the potential to improve outcomes through targeted investigation and secondary prevention. The investigators will undertake a systematic evaluation of the mechanism of myocardial injury and the role of coronary artery disease in 100 patients with elevated cardiac troponin concentrations where the diagnosis is likely to be type 2 myocardial infarction. These studies will help improve the assessment of patients with myocardial injury, refine the diagnostic criteria for type 2 myocardial infarction, and aid the design of future therapeutic trials.
This observational case-control trial sought to identify and characterize different exposures associated with nonfatal acute myocardial infarction in Costa Rican adults. Exposures assessed included dietary variables and adipose tissue fatty acids.
