Active clinical trials for "Myocardial Infarction"

the algorithm of artificial intelligent to diagnose myocardial infarction through prior surgery Electrocardiogram was established. The accuracy of using artificial intelligent to diagnose acute ST-segment elevation myocardial infarction and judge criminal vascular was evaluated.

The aim of the study is to investigate the adherence to prescribed post-infarction medication and to cardiac rehabilitation in patients after acute myocardial infarction. In addition, their impact on cardiovascular events will be investigated.

It has been shown retrospectively that participation and even the willingness improves the survival of patients after myocardial infarction or heart failure. We aimed to prospectively analyse the role of participation in cardiology trials on the survival of patients in a high volumen tertiary center.

Aims: evaluate the hydric status through bioimpedance spectroscopy in consecutive acute myocardial infarction patients referred for primary PCI; assessment of renal artery stenosis incidence through renal angiography in consecutive STEMI patients; fully characterize the complex hydration, metabolic and endothelial profile of these patients in the attempt to define the role played by dehydration in the complex dynamics of acute myocardial infarction.

The COVID-19 pandemic highlights the importance of the prognosis of co-morbidities, such as coronary artery disease, which significantly increase the risk of mortality in patients infected with SARS-CoV2. Investigators have recently studied the complex links between respiratory infections, particularly pneumonia, and type 2 myocardial infarction (MI) in many respects. The etiology of type 2 MI is based on an imbalance of myocardial oxygen supply/need in the absence of rupture/erosion of atheromatous plaques. Based on the RICO survey data, the investigators investigated whether COVID-19-related sepsis and/or respiratory failure could be an underlying mechanism of MI2.

To date, drug-eluting stents (DES) have become the standard of care in daily practice for the treatment of ischemic heart disease, by overcoming the risk of in-stent restenosis, a major issue raised in the bare-mare stents era. The application of potent anti-proliferative drugs and polymer structures that ensures sustained released of the drugs markedly reduced the neointimal hyperplasia, leading to much improved clinical outcomes compared with bare-metal stents. However, although first-generation sirolimus-eluting stents and paclitaxel-eluting stents significantly reduced the risk of in-stent restenosis and target-vessel revascularization, an augmented risk for very late stent thrombosis and fatal clinical events emerged as a new issue to be solved. Second- and newer- generation DESs adopted innovative stent platforms, novel stent materials, anti-proliferative drugs, and biocompatible polymers (including both durable and bioresorbable). Nowadays, numerous types of DESs (over 20 types) are available in clinical practice as well as bare-metal stents. However, little is known about the clinical outcome according to type of DESs in real-word practice. Given that many of recent randomized clinical trials (RCTs) demonstrate the 'non-inferiority' of brand-new DESs over older DESs in limited period time (usually for 1-year) in a selected patients eligible for RCTs, the real-world clinical outcomes according to type of DES implanted are still unveiled. Although, the question about the differential impact of generation of DES, type of biocompatible polymers (bioresorbable versus durable), thickness of stent struts and type of eluted anti-proliferative drugs are very important in clinical aspect of view, but there is little study conducted on all patients who are actually confronted in daily clinical practice. Korea operates national insurance system that covers most of the Koreans (97.1%) that are strictly monitored by National Health Insurance Service (NHIS). Of note, the claims database of NHIS of Korea contains all information including the demographic characters of patietns, diagnosis codes (ICD-9 and ICD-10), type of procedures or surgeries and the medical devices utilized, death certificates that contains type of death, and the drugs prescribe in outpatient clinic and hospitals in a individual pill level, that enables monitoring for the drug compliance. This unique feature of NHIS database allows the investigators to gain access to the dose and duration of cardio-protective medications including anti-platelet agents, lipid-lowering agents, anti-hypertensive agents, glucose-lowering agents, nitrate donors, vasodilators, and others. Given the benefits of NHIS database of Korea, we would like to establish a whole-population registry, named as COreaN NationwidE Claims daTa on Drug-Eluting Stent Registry (CONNECT DES Registry). A comprehensive analysis of this data is expected to shed new light on the impact of type of DESs and drug use in real-world practice that could be fully revealed through RCTs.

The aim of this study is to determine the miRNA expression profile in peripheral blood exosomes of patients with myocardial infarction and to investigate its relationship with myocardial infarction.

"MEtabolomics and MicrObiomics in caRdIovAscular diseases Mannheim (MEMORIAM) " is a single-center, prospective and observational study investigating to identify disease-specific metabolic, respectively microbiomic, patterns of patients with high-risk cardiovascular diseases. High-risk cardiovascular diseases comprise patients suffering from acute heart failure (AHF), ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI), sepsis, septic shock, ischemic and non-ischemic cardiomyopathy.

This study will assess relationship between ischemic time and the extent of myocardial infarction with cardiac magnetic resonance image in patients with STEMI (ST elevation myocardial infarction) and primary percutaneous coronary intervention.

Precise identification of the infarct scar is essential for successful catheter ablation of ventricular arrhythmias in patients with chronic myocardial infarction. Voltage mapping of endocardial electrograms is currently used to delineate the necrotic scar but this is influenced by the direction of the activation wave front and is not sensitive enough to differentiate distinct degrees of transmural injury in the scar. Mapping of local myocardial electrical impedance may overcome these limitations.
