Active clinical trials for "Myocardial Infarction"

Recently, a predictive model has been developed to assess the risk of myocardial infarction or cardiac arrest (MICA) during and after surgery using the American Society of Surgeons' National Surgical Quality Improvement Program (NSQIP) database. In this MICA model, 180 hospital databases were used in 2007 and 2008 and included more than 200 000 patients. The Gupta score developed with this MICA model identified five predictors of perioperative myocardial infarction and cardiac arrest: type of surgery, functional status, creatinine increase (>130 mmol/L or >1.5 mg/dL), age, and American Association of Anesthesiologists (ASA) class. The Gupta score is presented as an interactive risk calculation program in the 2014 guideline of the ACC/AHA. The risk can be calculated simply and accurately at the bedside or clinic. The Gupta score is in spreadsheet format and can be downloaded online at http://www.surgicalriskcalculator.com/miorcardiacarrest. Unlike the previously used indexes, a scoring system has not been established. An estimate of the probability of myocardial infarction/cardiac arrest is provided for individual patients. In this study, the primary aim was to compare the frequency of cardiology consultation requests according to the use of the Gupta score. The secondary aim is to evaluate the perioperative clinical results (coronary angiography, ECHO, acute coronary syndrome, arrhythmia, 30-day mortality, etc.).SPSS 21.0 (Version 22.0, SPSS, Inc, Chicago, IL, USA) program will be used for statistical analysis. After applying the Shapiro-Wilk test for normality, the student's t-test will be used if the distribution is normal, and the Mann-Whitey U test will be used if the distribution is not normal. Fisher's exact test or chi-square test will be used for categorical variables. Results p<0.05 will be considered significant.

To investigate the prognostic impacts of the atrial fibrillation burden (AFb) in acute myocardial infarction (AMI) patients who developed paroxysmal new-onset atrial fibrillation (NOAF) during the index AMI hospitalization.

Trimethylamine N-oxide (TMAO) is a gut microbiota-dependent metabolite of dietary choline, L-carnitine, and phosphatidylcholine-rich foods. On the basis of experimental studies and patients with prevalent disease, elevated plasma TMAO may increase risk of atherosclerotic cardiovascular disease (ASCVD). However, to our knowledge, no data is available on its impact on coronary microcirculation.

This was a retrospective study using the Taiwan's National Health Insurance Research Database (NHIRD). The study employed two study designs for different purposes as follows: A cross-sectional analysis was conducted to explore the annual incidence trends. A longitudinal cohort study was conducted to assess baseline characteristics, treatment patterns, long-term healthcare utilization, and cause-specific mortality among incident AMI patients. In each part, the study was conducted for AMI, and separately for ST-segment elevation and non-ST- segment elevation myocardial infarction (STEMI and NSTEMI)

A single center, prospective, observational study to compare fractional flow reserve (FFR) and intravascular ultrasound (IVUS) percutaneous coronary intervention (PCI) optimization strategies on the functional PCI result (assessed with FFR) immediately post PCI and at 9-12 months after the treatment of long coronary artery lesions.

ST-segment elevation myocardial infarction (STEMI) remains among the most acute and critical diseases, with primary percutaneous coronary intervention (pPCI) and thrombolysis as mainstay reperfusion treatments. Real-world implementation of current guidelines for STEMI management has been assessed in developed countries and large Chinese cities. However, until now, there has been no registry on patients with STEMI in Henan, the most populated (about 100 million) and predominantly rural (66%) province in central China. This registry is aimed to assess management practices, time delays, outcomes and reasons for not receiving reperfusion therapy in consecutive STEMI patients in reperfusion-capable hospitals, i.e., tertiary and secondary, in Henan province.

Prophylactic substrate ablation in post-MI patients undergoing defibrillator implantation reduces appropriate defibrillator therapies.

The purpose of this study is to validate a practical risk score to predict the mechanical complication of ST-elevation myocardial infarction (STEMI).

The purpose of this study is to determine the predictors of right ventricular damage (RVD) assessed by wall motion abnormalities, edema, myocardial salvage and delayed enhancement (DE)cardiac magnetic resonance imaging in acute ST-elevation myocardial infarction (STEMI) and its prognostic significance. The investigators hypothesize that ischemia related changes of the myocardium are also visible in the right ventricle and that they have an impact on patient outcome.

To characterize and estimate the size of different populations with a history of acute coronary syndrome in Sweden. To assess the burden of illness (co-morbidities, mortality rates healthcare resource utilization and atherothrombotic events) among patients with a history of myocardial infarction (MI) 1-3 years ago and additional risk factors for atherothrombosis.
