View clinical trials related to Myocardial Infarction.
Filter by:ST-segment elevation myocardial infarction (STEMI) is an acute condition that accounts for 75% of sudden deaths in adults over 35 years of age and more than half of all cases of chronic heart failure. However, the mechanism of myocardial infarction remains poorly understood. At present, there is no national information system for myocardial infarction, as there is for other diseases such as multiple sclerosis (OFSEP cohort). The purpose of this cohort is to enable studies and research projects to be carried out on the descriptive epidemiology of myocardial infarction, monitoring of patients undergoing treatment (safety, efficacy), quality of life and functional consequences of infarction, and research into new biological and imaging prognostic biomarkers. Its general objective is to provide researchers, hospital practitioners, medical interns, academics or industrialists with a quality epidemiological tool for research.
The purpose of this research is to find out if patients with Type 2 Myocardial Infarction (T2MI) without significant epicardial coronary artery disease (CAD) have a greater chance of having coronary microvascular disease (CMD).
This study seeks to investigate the clinical value of novel biomarkers and echocardiographic indices, including myocardial work parameters, in patients with first acute myocardial infarction. The relationship between novel echocardiographic indices with clinical data, biochemical data in different myocardial infarction types will be attempted. Prognostic implications of those indices will be explored.
The goal of this clinical trial is to demonstrate the improvement in Coronary Microcirculation Dysfunction (CMD) with Super Saturated Oxygene (SSO2) therapy in patients with anterior ST-segment Elevation Myocardial Infarction (STEMI) successfully revascularized by percutaneous coronary intervention (PCI). Participants will receive SSO2 therapy for 60 minutes, which aims to overoxygenate their blood. Improvement in CMD will be assessed by comparing angio-IMR before and after 60 minutes of SSO2 therapy measured on conventional angiographic images.

Prospective, randomized, controlled, multicenter, open-label trial to study whether multivessel percutaneous coronary intervention (PCI) is superior over culprit-lesion only PCI in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and multivessel coronary artery disease.
Primary percutaneous coronary intervention (PCI) is the preferred revascularization strategy for patients with acute ST-segment elevation myocardial infarction (STEMI). Compared with bare-metal stents (BMS) and early-generation thick-strut polymer-based drug-eluting stents (DES), newer-generation DES with thinner strut stent platforms and durable or biodegradable polymers have been shown to improve long-term safety and efficacy outcomes among patients with STEMI. Accordingly, the use of newer-generation DES over BMS is currently recommended by the most recent guidelines. Vessel healing at the culprit site after DES implantation is however substantially delayed in patients with acute STEMI as compared to those with chronic coronary syndromes and is associated with a long-term risk for recurrent stent-related adverse clinical outcomes. These findings highlight the need for future iterations in modern DES technology to further improve clinical outcomes following PCI in this highest-risk patient subset. Current guidelines recommend dual antiplatelet therapy (DAPT) consisting of aspirin and a potent P2Y12 receptor inhibitor for 12 months after primary PCI for STEMI, unless there are contraindications such as excessive risk of bleeding. A recent meta-analysis of five large-scale randomized clinical trials including a total of 32'145 patients, of whom 4,070 (12.7%) patients were treated for STEMI, indicated that 1-3 months of DAPT followed by P2Y12 inhibitor-based single antiplatelet therapy (SAPT) after second-generation DES implantation in patients with chronic and acute coronary syndromes was associated with lower risk for major bleeding and similar risk for stent thrombosis, all-cause death, myocardial infarction, and stroke compared with conventional DAPT. These findings suggest that a potent P2Y12 inhibitor-based SAPT following a short DAPT course (1-3 months) may represent a preferable treatment option, which is associated with similar ischemic, but lower bleeding risk, for patients undergoing PCI with newer-generation DES compared to standard conventional 12 months DAPT. The question of whether SAPT using a potent oral P2Y12 inhibitor (ticagrelor or prasugrel) without aspirin (aspirin-free strategy) after primary PCI with a newest-generation thin-strut polymer-free drug-eluting stent is safe and effective compared to a conventional guideline-recommended 6- to 12-month DAPT course among patients with STEMI remains uncertain.
The aim of this study is to assess the efficacy of an innovative program of secondary cardiovascular prevention focused on patient empowerment. This program will be characterized by a blended interaction between healthcare workers and the patients: first, a face-to-face first encounter in-hospital for risk factors profiling, followed by remote interactions through a digital approach. The digital intervention is targeted at promoting the adoption and retention of virtuous behavior (e.g. smoking cessation, healthy eating habits, physical exercise, regular assumption of pharmacological therapies), improving cardiovascular risk factors control. Moreover, an exploratory endpoint will be investigated: the reduction of the residual coronary risk.
Heart attacks caused by the complete blockage of a heart artery are treated by opening it with a stent. However, most people will also have 'non-culprit' narrowings found in their other arteries at this time. Although in general people do better if these non-culprit narrowings are also treated with stents if they look severe, this process has problems. This is because narrowings that look severe may be stable and not cause any trouble. For these people a stent is a wasted procedure and unnecessary risk. On the other hand, narrowings that are currently left alone because they appear mild, may progress and cause a heart attack. Participants who have had a heart attack will have a scan from inside the heart arteries during an angiogram (optical coherence tomography, OCT) and a magnetic resonance angiogram (MRA). If the investigators can show that it is possible to accurately predict which non-culprit narrowings are going to progress and which are going to stabilise, medical professionals may be able to better target their treatments after a heart attack.
