ST Elevation Myocardial InfarctionThe goal of this clinical trial is to learn about the effectiveness of Umbilical Cord Mesenchymal Stem Cell (UC MSC) therapy in patients with STEMI against infarct myocardial size reduction and prevent the incidence of heart failure in the future
Effect of Nivolumab vs Placebo in Patients With Acute Myocardial Infarction: A Randomized Clinical...
Acute Anterior ST Segment Elevation Myocardial InfarctionMyocardial infarction (MI) is a major contributor to morbidity and mortality in China. The goal of this interventional, randomised controlled clinical trial is to evaluate the effectiveness and safety of a single administration of Nivolumab to the patients presenting with an acute anterior ST-segmental elevated myocardial infarction. Researchers will investigate if Nivolumab treatment can effectively and safely reduce infarct size as well as improve cardiac function of the patients with acute myocardial infarction.
Effects of Pressure-controlled Intermittent Coronary Sinus Occlusion (PiCSO) Therapy on miRNAs Expression...
Anterior Myocardial InfarctionIn this study we pretend to determine the molecular (miRNAs expression, angiogenic and inflammatory biomarkers) and microcirculatory (assessed by the innovative continuous intracoronary thermodilution technique) effects of PiCSO compared to a standard PCI control group in patients with high-risk anterior STEMI. Then, we aim to assess the efficacy of these molecular biomarkers as prognostic tools. Also, we will evaluate the impact of PiCSO on the coronary microcirculation beyond the acute phase in the follow-up six months after STEMI. Finally, we will assess PiCSO influence on Heart Failure (HF) clinical variables and patients' quality of life including a cost-effectiveness assessment in the mid-term follow-up one year after the STEMI event.
STEMI Treated With a Polymer-free Sirolimus-coated Stent and P2Y12 Inhibitor-based SAPT Versus Conventional...
ST Elevation Myocardial InfarctionPrimary 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.

Can Hypothermia be Incorporated Into Primary Angioplasty for Heart Attack?
ST-Elevation Myocardial InfarctionThe hypothesis of this study is that consciously sedated patients suffering from ST-elevation myocardial infarction can be rapidly and safely cooled to a state of therapeutic hypothermia (32 to 34 degrees C) using the LRS ThermoSuit System prior to percutaneous coronary intervention.
Predictors of Failed Thrombolysis in Acute Myocardial Infarction
STEMI - ST Elevation Myocardial InfarctionThe purpose of this observational study is to assess why thrombolytic treatment with tissue-plasminogen activator (t-PA) fails in patients with acute ST-segment elevation myocardial infarction (STEMI). The study will include 200 STEMI patients at the time of arrival at Oslo University Hospital Ullevål after receiving prehospital thrombolysis. A blood sample will be taken immediately for the study of factors related to coagulation, fibrinolysis and inflammation. Levels of the biomarkers will be compared between patients with successful and failed thrombolysis.
