Filter by:This study aims to evaluate procedural and clinical outcomes of acute coronay syndrome (ACS) patients with aneurysmatic culprit right coronary artery (RCA).
Guideline recommended evidence-based clinical care correlates with improved patient outcomes. In real life care, however, adherence to guideline recommendations remains suboptimal. In real life, patients may receive suboptimal treatment and as a result treatment targets are not always met. To support and improve secondary prevention for cardiovascular disease, PENELOPE and PENELOPE-CTRL are designed to support guideline implementation on lipid management and provide valuable feedback to care-givers on real world data.
This study is a retrospective case-control study. In this study, through untargeted metabolomics, investigators identified several specific changed serum metabolites in T2DM patients with or without AMI and their functions/category. Moreover, researchers selected several endogenous candidate biomarkers with larger fold change for validation in expanded population to find biomarkers which effectively predict the development of STEMI in patients with T2DM.
Patients with acute coronary syndromes (ACS) have an increased risk of recurrent ischemic events, particularly during the first year following the index event, which is mainly due to unattended risk factors and/ or poor compliance with medications. Lowering low-density lipoprotein cholesterol (LDL-C) reduces cardiovascular morbidity and mortality in patients with atherosclerotic cardiovascular disease (ASCVD), with a magnitude of clinical benefit that is proportional to the reduction in LDL-C levels. Proprotein convertase subtilisin/ kexin type 9 (PCSK9) antibodies have emerged as a new class of drugs that rapidly and effectively lower LDL-C levels up to 77 % of the original value in combination with statins. The primary objective of this study is to confirm the safety and the long-term clinical benefit associated with the use of PCSK9i when combined with statin in patients with ACS-STEMI. The study is an investigator-initiated, prospective, randomized, open label study that will be the first study looking for the safety and the clinical benefit and outcome associated with the use of PCSK9i in ACS-STEMI patients specifically. Internationally, this will be the first trial studying the effect of PCSK9i on patients with acute myocardial infarction (STEMI) in terms of reduction in cholesterol level and reduction in cardiac events rate (re-infarction and cardiac death) after myocardial infarction. This trial will have a significant impact in the management of patients with STEMI, locally and internationally and it will be conducted purely in Qatar. This trial will help to improve the clinical outcome of patients in Qatar in terms of reduction of myocardial reinfarction rate and mortality.
To assess the prognostic value of systemic arterial lactate levels in patients with ST segment elevation myocardial infarction undergoing primary PCI and correlate with the results of primary PCI and 30 days MACE follow up.
The aim of this study is to assess the impact of culprit-first versus culprit-last percutaneous coronary intervention on the door to balloon time and clinical outcomes in patients with ST-elevation myocardial infarction.
Radial approach is widely established in cardiac diagnostic and therapeutic treatments. It has been shown to decrease bleeding, vascular problems, and mortality rates when compared to the femoral approach. It also offers better comfort to patients through early mobility and lowers hospital expenses. Previously, there were no specific devices for radial artery hemostasis. Many different types of dressings were used in various hospitals with no standardization. This raises the question of whether specific devices surpass dressings in terms of patient comfort, time required to maintain hemostasis, and vascular complications. The primary goal of this study was to examine the effectiveness of compression dressings and hemostatic wristbands on patients undergoing cardiac procedures via radial approach in terms of patient comfort, time required to maintain hemostasis, and vascular problems. The hemostatic wristband TR BandR (Terumo Corporation, Tokyo, Japan) was utilized in one group, while compressive elastic dressing, standardized as 13 threads gauze overlapped, opened, longitudinally pleated once and wrapped, making a 5-cm long cylinder, 1-cm in height, was used in the other.
Angiographic no-reflow during primary PCI procedures occurs at relatively high rate (25%) and is associated with worsening of long term morbidity and mortality. The exact mechanism of no-reflow is not fully understood, yet it is believed to be multifactorial including microvascular plugging with activated platelets and thrombotic debris in addition to the microvascular dysfunction from the ischaemia-reperfusion injury. Despite a theoretical advantage of glycoprotein IIb/IIIa inhibitors (GPi) (like; Tirofiban) to suppress the intense platelets' activation/reaction; their use did not lead to a significant net benefit, because it was opposed by increased risk of bleeding. However, the bleeding that plagued GPi use was predominantly related to vascular access in the era femoral approach was the default. Moreover, there are some recent data suggesting that small intracoronary bolus of GPi was non-inferior to intravenous bolus-infusion dose with less bleeding events. This study plans to assess upfront premedication with small doses of GPi + Nitroglycerin ± Verapamil, with staged restoration of flow (repeated balloon inflation) to reduce angiographic no-reflow and CMR assessed microvascular occlusion (MVO).
Patients with STEMI are usually treated with primary PCI in contemporary practice. However, primary PCI is currently deemed unbeneficial or potentially harmful in patients presenting late after a STEMI. There is limited data to suggest that patients who may have viable myocardium despite presenting late with a STEMI may derive benefit from PCI, which may be denied in current practice. CMR imaging is the reference modality for assessment of left ventricular function and myocardial viability. This feasibility study will randomise late presenting STEMI patients with CMR documented viability to PCI plus optimal medical therapy (OMT) versus OMT alone. The investigator hypothesises that PCI in this cohort will improve left ventricular remodelling and function. Favourable results will lead to an adequately powered multi-centre trial with the potential to improve the management of late resenting STEMI patients and impact on clinical practice guidelines.
This study is a prospective cohort study，we want to observe the changes of different cardiovascular antibody levels in STEMI patients undergoing emergency PCI;and combined with different cardiovascular antibody levels and various indicators, evaluate the impact of ischemia-reperfusion injury and prognosis in STEMI patients after emergency PCI.
