Filter by:The aim of Multiplaque clinical study is to assess the vulnerability degree of the atheromatous plaques, before and after a myocardial infarction (MI), based on multiomics analysis, associated with invasive and non-invasive data. In this study, a multi-parametric model for risk prediction will be developed, for evaluation of the risk that is associated with the vulnerable coronary plaques in patients that have suffered an acute coronary syndrome. In the study, evaluation of the imaging characteristics of these coronary plaques will be performed with the use of CT, OCT, IVUS and invasive angiography. We will study the correlation between plaque evolution and (1) the degree of vulnerability at baseline, (2) multiomics profile of the patients and (3) clinical evolution during follow-up. Also, new techniques for evaluation of the functional significance of coronary stenoses will be studied and validated, such as calculation of the fractional flow reserve or determination of shear stress in areas that are localized within the near vicinity of the vulnerable coronary plaques.
Dual Antiplatelet Therapy (DAPT) with aspirin and P2Y12 receptor inhibitor remains a cornerstone in the secondary prevention of coronary artery disease (CAD). Clopidogrel is one of the most commonly used antithrombotic agent that inhibits the platelet P2Y(12) adenosine diphosphate (ADP) receptor. Ticagrelor is an oral, reversibly-binding, direct-acting P2Y12 receptor antagonist used clinically for the prevention of atherothrombotic events in patients with acute coronary syndromes (ACS). Guideline recommendations on the use of dual antiplatelet therapy have been formulated that ticagrelor 90 mg twice daily plus aspirin in preference to clopidogrel 75mg daily plus aspirin for ACS patients. The previous studies have reported that half-dose ticagrelor had the similar inhibitory effect on platelet aggregation as the standard-dose ticagrelor, which was significantly stronger than that in the clopidogrel group. One-quarter standard-dose ticagrelor provided greater degree of platelet inhibition than standard dose clopidogrel in Chinese patients with stable CAD. But the effectiveness and safety of low-dose ticagrelor remain yet not very clearly in Chinese patients with acute coronary syndrome undergoing percutaneous coronary intervention.
Frailty is known as an independent risk factor for morbidity and mortality in older cardiac patients . It is an important factor on the cardiologist decision between conservative and invasive treatment in older patient with acute coronary syndrome, and is usually made subjectively by the cardiologist known in the literature as eyeball testing. in this study the investigators will compare the cardiologists eye ball testing to objective frailty assessment based on Fried score and Edmonton frailty scale.
The objective of this study is to analyze the Demographics, Clinical Profiles, Management, in-Hospital and Long-Term Outcomes of Patients with Acute Coronary Syndrome Syndrome And Myocardial Infarction with Non-obstructive Coronary Artery Disease.
H-REPLACE trial is a prospective, randomized, open-label, active-controlled, multicenter study in participants with ACS (STEMI or NSTEMI, unstable angina). All eligible participants receiving background treatment of aspirin plus clopidogrel or ticagrelor will be randomly assigned to either oral rivaroxaban 2.5 mg twice daily or rivaroxaban 5 mg twice daily or subcutaneous (SC) enoxaparin 1mg/kg twice daily until hospital discharge or 12 hours before revascularization therapy for a maximum of 8 days.
A multinational, prospective and observational study that will assess the management of ACS in real-life practices in Middle East North Africa area.
Obstructive sleep apnea (OSA) is an increasingly common chronic disorder in adults that has been strongly associated with various forms of cardiovascular disease. Compared to the general population, OSA occurs more often in patients with acute coronary syndrome (ACS). Although percutaneous coronary intervention (PCI) is nowadays part of standard therapy and optimal medical therapy has been used to manage traditional risk factors, the long-term cardiovascular outcomes after index ACS remain suboptimal. Some preliminary data suggest OSA is associated with higher risk of subsequent cardiovascular events in ACS patients. However, the study population was heterogeneous and these studies were not done in the context of new-generation drug-eluting stents and intensive antiplatelet therapy, thus precluding definite conclusions. Furthermore, a cardioprotective role of OSA in the context of acute myocardial infarction (AMI), via ischemic preconditioning, has also been postulated. Due to the inconsistent evidence, the investigators performed a large-scale, prospective cohort study to delineate the whole picture of the association of OSA with short- and long-term outcomes of patients with ACS. Whether treatment of OSA (eg. continuous positive airway pressure (CPAP)) would prevent these events will also be evaluated. Moreover, the investigators will assess the potential mechanisms of OSA-induced atherosclerosis and myocardial injury in ACS patients.
Ticagrelor is a potent and fast-acting P2Y12-ADP receptor antagonist recommended as first-line agent in ACS (2). This drug was associated with a 20% relative reduction in the rate of MACE in ACS patients undergoing PCI compared to clopidogrel. This benefit came without any increase in major bleedings compared to clopidogrel (6). In the PLATO trial, a limited number of kidney failure patients were included (21%) and patients with terminal CKD were excluded. A sub-group analysis focused on CKD patients was performed. Only 214 patients with CKD below stage 4 (creatinine clearance <30 ml/min) were included (7). No patient with terminal CKD or undergoing chronic hemodialysis was included. Of importance, kidney function impairment is frequent and affects up-to 40 % of ACS patients. In addition, CKD is a powerful independent predictor of ischemic complications during ACS (8-9).Indeed, CKD patients have a very high risk of MACE following ACS with an odd ratio between 2 and 3 compared to patients with normal kidney function and event rates above 40% at one year follow-up (8-13). Of importance these patients more often have high on-clopidogrel platelet reactivity which was strongly associated with a worse clinical outcome (3,14-16). In CKD patients HTPR was associated with death after PCI (15). Accordingly ticagrelor which overcomes these limitations of clopidogrel could be associated with a major clinical benefit in severe or terminal CKD patients. Most of ticagrelor and is active metabolites are excreted through the feces. Preclinical data suggested that renal impairment had little effect on systemic exposure to the drug(EMEA/H/C/1241 (28)). Recent pharmacodynamic and kinetic studies confirmed these preclinical data on the safety of ticagrelor in severe and end-stage CKD (17-19). Therefore based on the rational above and to the lack of relevant clinical data, the optimal P2Y12-ADP receptor antagonist for patients with stage 4 and 5 and patients undergoing chronic dialysis remains undetermined in ACS treated with PCI. We aimed to compare the clinical efficacy ticagrelor and clopidogrel in patients with stage 4 and 5 or on chronic hemodialysis undergoing PCI for ACS.
Lorraine is one of the most affected French region by cardiovascular diseases with a mortality rate for ischemic heart disease higher than the national average in 2010. Due to practice change with the new recommandations of the European Society of Cardiology involving the myocardic revascularization, the investigators wanted to compare the Stemi care in 2005-2006, 2010-2011 and 2015 in the CHR Metz-Thionville.
Mood disorders, anxiety disorders, and trauma-related stress (MD\AD\TRS) are common among men, particularly those suffering from heart disease (HD). MD\AD\TRS are significantly related to exacerbation of HD symptoms that often lead to death. Unfortunately, men are significantly less likely than women to seek and receive appropriate treatment for their mental health issues including MD\AD\TRS. Furthermore, there is little literature about the use of the stepped care model in the Canadian setting. The overarching goal of this interventional program is therefore to prevent, early detect and treat MD\AD\TRS in men living with HD. This Participatory Action Research aims to implement a stepped-care model for MD\AD\TRS in men in New Brunswick, Ontario, and quebec. The second phase of the project proposes a quantitative study that will consist of testing the effectiveness and acceptability (by the men and the involved health professionals) of the stepped-care model. It will offer to post ACS-males a mental health related component presently not available in the typical services of the NB health system. Data will be collected at baseline (0 month) and at four follow-up (each 3-months) sessions to manage the progress of each participant throughout their 12-month journey in the study. Typical sociodemographic data will be collected, along with a questionnaire on Masculinity Norms, Couples Satisfaction (when applicable), and four mental health assessment tools.
