Active clinical trials for "Infarction"

To explore the protective effect of prostaglandin sodium on coronary microcirculation function and ventricular remodeling after reperfusion treatment of acute ST-segment elevation myocardial infarction.

The COVID-19 pandemic has had dramatic effects on health systems and on non-COVID health care. Using French inpatient claims data and retrospectively collected clinical data, the investigators will assess the changes in hospital admissions for acute cardiovascular and neurovascular conditions in France during and after the national lockdown.

Acute myocardial infarction (AMI) is a life-threatening condition and a cause of functional disability. After reperfusion therapies and pharmacological strategies, patients suffered great pain physically and mentally. How to improve the quality of life and the prognosis in patients with AMI is a hot topic in the field of cardiac rehabilitation now. In this study, a randomized, controlled and prospective clinical trial is designed for patients with AMI to improve exercise capacity, cardiometabolic parameters, as well as quality of life by an individualized, low-cost exercise intervention we developed after evaluation by Cardiopulmonary Exercise Tests (CPET). Serial CPET are performed to prospectively measure changes in aerobic exercise capacity, and the MOS item short form health survey（SF-36）are constructed to survey life quality. What's more, echocardiography and NT-proBNP are also assessed.

Cumulative evidence has demonstrated that cardiac repair after acute myocardial infarction (AMI) is characterized by a series of time-dependent events orchestrated by the innate immune system. This begins immediately after the onset of necrotic cell death with intense sterile inflammation and myocardial infiltration of a variety of immune cell subtypes including monocytes and macrophages during the first several days after MI. There is increasing evidence to suggest inflammation is not limited to the infarcted myocardium and systemic imbalances in the post-infarct inflammatory cascade can exacerbate adverse remodelling beyond the infarct site. Therefore, it is very important that therapies seek to target the intricate balance between pro- and antiinflammatory pathways timely after AMI. Human mesenchymal stem cells (hMSCs) have been shown to exhibit immunomodulation, angiogenesis, and paracrine secretion of bioactive factors that can attenuate inflammation and promote tissue regeneration, making them a promising cell source for AMI therapy. However, it has been proved in our and other studies that perfusion of WJMSCs after 5 days of AMI can only slightly improve left ventricular end-diastolic volume, which is the most important indicator of left ventricular remodeling. Thus, WANIAMI Trial is a randomized, double-blind, placebo controlled, phase#study designed to assess the safety and feasibility of intravenous infusion of WJMSCs in the treatment of patients in the acute phase ( within 24h) with the both of ST-Segment-Elevation or Non-ST-Segment-Elevation AMI.

The aim of the current study is to test the clinical performance of the everolimus-eluting BVS compared with that of the durable polymer everolimus-eluting stent (EES) in patients undergoing PCI in the setting of acute MI.

To evaluate the effective and safety of post-dilatation in patients with acute ST segment elevated myocardial infarction undergoing primary percutaneous intervention after thrombus aspiration assessed by optical coherence tomography to examine stent Incomplete apposition and strut coverage in patients treated with drug-eluting stents .

The purpose of the prospective, randomized and a multicenter trial is to compare clinical outcome in patients presenting with ACS, treated with PCI using Optimax-BAS versus Synergy-EES. Second objective is to explore whether the Optimax-BAS use is superior compared with Synergy-EES use with respect of hard end points (cardiac death, MI and major bleeding).

Using placebo as control, The purpose of this study is to evaluate the efficacy and safety of methanesulfonic acid cinepazide injection to relieve disabled degree of acute cerebral infarction patients, and explore the best safe and effective dose as well as dose method.

The purpose of this study is to demonstrate that a BioFreedom™ Drug Coated Stent is non-inferior to a bare metal stent at one year as measured by the composite safety endpoint of cardiovascular death, myocardial infarction and definite/probable stent thrombosis, and that its efficacy is superior to a bare metal stent as measured by clinically driven TLR at one year.

Objective: Statins have been shown to have beneficial pleiotropic effects besides being lipid lowering. The investigators hypothesized that early and intensive statin treatment was associated with improved left ventricular (LV) function and with a stabilization of the coronary atherosclerotic plaques in patients with acute myocardial infarction (AMI) Method: In a prospective randomized blinded endpoint trial patients with ST segment elevation or non ST segment elevation AMI were randomized to either intensive statin-therapy (loading dose rosuvastatin 80 mg immediately after randomization followed by 40 mg daily) or usual statin therapy (simvastatin 40 mg daily). Patients were followed 12 month and the investigators performed echocardiography at randomization, after 30 days and after 12 month. The investigators used 2D Speckle Tracking for the assessment of LV-function. Coronary plaque assessment was done with Cardiac-CT (MSCT) at baseline and after 12 month. Primary outcome for this study was assessment of LV function with global and regional myocardial strain. Secondary outcomes can be divided in 4 groups: Additional echocardiographic measurements such as Ejection Fraction, S´, LV-volume, atrial volume, VA-coupling, diastolic function, post systolic strain and strain rate. Biochemical assessment of inflammation and endothelial function: Hs-CRP, ICAM, VCAM, E-selection and Nitrate/Nitrite ratio. Coronary plaque assessment by MSCT: Plaque volume and plaque stability. Long term follow-up: Mortality and cardiovascular events
