Active clinical trials for "Infarction"

Randomized comparison of abciximab i.v. versus i.c. in patients with STEMI undergoing primary PCI. The hypothesis is, that higher concentration of abciximab i.c. leads to improved epicardial flow, perfusion, reduction of no-reflow, reduction in infarct size and subsequently better outcome.

Study hypothesis: the Stentys self-expandable Stent results into a better alignment of the struts to the vessel wall than a balloon-expandable stent within a few days after the procedure in acute myocardial infarction patients.

Ischemic postconditioning can reduce myocardial injury following myocardial infarction. A potential pharmacological agent is the anesthetic Sevoflurane. The investigators' hypothesis is that sevoflurane during primary percutaneous coronary intervention (PCI) will reduce infarct size.

The routine use of glycoprotein (Gp) IIb-IIIa inhibitor such as abciximab is not recommended by current ACC/AHA guideline (Class IIb, level of evidence of A). This may be partly due to potential increase of bleeding. Compared bolus injection followed by continuous infusion of Gp IIb-IIIa inhibitor, single bolus administration was proposed to decrease bleeding complication while maintaining decrease ischemic events. It was also reported that direct intracoronary injection of abciximab might be superior to intravenous injection regarding myocardial perfusion. Aspiration thrombectomy is regarded as important adjunctive therapy in the treatment of acute ST-elevation myocardial infarction (IIa, level of evidence of B). We hypothesized that combination of intracoronary abciximab bolus injection and aspiration thrombectomy might enhance adequate myocardial perfusion in patient with acute ST-elevation myocardial infarction. We will determine whether combination of intracoronary abciximab injection and aspiration thrombectomy is superior to each treatment only in terms of myocardial perfusion through index of microcirculatory resistance and cardiac magnetic resonance imaging.

Emerging evidence suggests that stem cells and progenitor cells derived from bone marrow can be used to improve cardiac function in patients after acute myocardial infarction. In this randomised trial, we aim to assess whether intracoronary transfer of autologous bone-marrow cells could improve myocardial viability at 3 and 12 months' follow-up.

This is a randomized, double blindcontrolled, parallel group, multi-center, multinational study of fondaparinux vs. control in patients with STEMI (ST segment myocardial infarction) randomized within 24 hours of the onset of symptoms.

The EMERALD II study is a multinational, multicenter, and retrospective study. ACS patients who underwent CCTA from 1 months to 3 years prior to the event will be retrospectively identified. Plaques in the non-culprit vessels will be regarded as a primary control group.

The purpose of this pharmacokinetic (PK) study is to characterize the maximum concentration (Cmax) and time-to-maximum concentration (Tmax) of Biolimus A9TM and its active metabolites sirolimus and everolimus in a cohort of coronary artery disease (CAD) patients following implantation of BioFreedomTM SS stent.

There is a clear need to develop improved tools to stratify risk in patients who seek emergency care for chest pain, one of the most common and potentially deadliest conditions encountered in acute care settings. The ECG has been the mainstay of initial evaluation of chest pain patients, yet is currently only diagnostic for a small subset of patients with ST-elevation myocardial infarction. Prior studies have identified candidate markers of ECG characteristics and preliminary algorithms that can identify patients with non-ST elevation myocardial infarction as well as those with very low risk of coronary artery disease. This study will enroll a cohort of consecutive chest pain patients needed to confirm the accuracy of these ECG markers and determine their maximal clinical utility as part of a risk stratification tool. With these improved tools, emergency providers (physicians, nurses, and paramedics) will be able to streamline the care provided to these patients beyond the costly and time-consuming overnight observation for serial cardiac enzymes and provocative testing.

This trial is the pilot phase of a randomized controlled trial to test the feasibility of recruiting patients with a type 2 myocardial infarction and randomizing them to low-dose rivaroxaban to reduce the risk of major cardiovascular events.
