Filter by:Elevated on-treatment platelet reactivity is an independent risk factor of major adverse cardiovascular events following percutaneous coronary intervention or ACS. People living with HIV patients have a higher risk of recurrent events after ACS than people without HIV. The investigators hypothesized that this increased risk is driven by higher platelet reactivity. Using a nested case-control study design, HIV-infected and HIV-uninfected patients with a first episode of Acute Coronary Syndrome (ACS) treated with percutaneous coronary intervention were matched for age, sex, known diabetes mellitus and anti-platelet therapy. The primary end-point was the residual platelet reactivity (RPA) on dual antiplatelet therapy assessed by light transmission aggregometry (LTA, 20µM ADP). The study was conducted in a two large public university hospitals in central Paris, France.
The EMERALD trial is a multinational, multicenter study. The patients presented with AMI/definite evidence of plaque rupture and had underwent coronary CT angiography from 1 month to 2 year prior to the event will be retrospectively searched. Plaques in the non-culprit vessels will be regarded as internal control to the ruptured plaque in the culprit vessel.
In the management of adult chest pain patients presenting to an Emergency Department (ED) with suspected acute coronary syndrome (ACS), we aimed to evaluate the diagnostic accuracy of the combined use of a modified Thrombolysis in Myocardial Infarction (TIMI) score and a modified HEART score with high-sensitive cardiac troponin T (hs-cTnT) to rule out major adverse cardiac events (MACE) in 30-days.
Aim: To identify psychological and socioeconomic predictors of cardiac-rehabilitation (CR) attendance and uncover mechanisms of CR non-attendance. Design: Quantitative, observational, prospective study. Hypothesis a: Educational-level, comorbidity, anxiety, depression, self-efficacy, cohabitation and distance from residence are predictors of CR attendance. Hypothesis b: The expected social gradient in CR attendance is explained partly by differential exposure of comorbidity, anxiety, depression, self-efficacy, cohabitation and distance to the rehabilitation clinic.
This prospective observational study will evaluate and compare the sensitivity and specificity of the Modified TIMI, HEART and SACS Scores for accurately predicting the presence and absence of obstructive coronary artery disease (OCAD) as diagnosed during coronary angiography in the cardiac catheterization suite. In addition, we plan to determine if a variant of SACS, HEART, TIMI, or a hybrid score resulting from combining formulas from two or all three scores yields a new tool that exceeds the predictive performance of all three current models for determining the absence or presence of OCAD.
The aim of this research is to evaluate the effect of early invasive therapy and appropriate revascularization compared with conservative management and selective revascularization among women with an acute coronary syndrome.
The Purpose of this study is to evaluate the incidence of delirium in patients with acute coronary syndromes admitted to a Intensive Care Unit Patients.
The primary aim of the study is to investigate new cardiac biomarkers and algorithms to diagnose acute coronary syndrome in patients with suspected acute myocardial infarction.
In the POPular CABG study we investigate if the addition of ticagrelor, a drug that inhibits blood platelets from clotting, to treatment with aspirin will reduce the rate of saphenous vein graft occlusion as assessed with coronary computed tomography angiography at 1 year after coronary artery bypass grafting surgery.
The first aim of the study is to prove that after starting the therapy with crushed tablets, the platelet inhibition will be as expected after starting therapy with intact tablets. Gurbel et al. showed that 100% of the patients on ticagrelor treatment have a decrease from baseline platelet aggregation of >10% 4 hours after last maintenance dose. So the investigators expect that after 3 days of treatment, all of our patients will have a closing time of more than 106seconds. The investigators will observe two different clinical conditions of Acute Coronary Syndrome. First after semi-urgent coronary artery bypass graft (CABG) surgery, secondly in patients after cardiac arrest. Both are clinical situations in which crushed tablets are needed to give. The second objective is to determine plasma concentrations of Ticagrelor and AR-C124910XX (active metabolite of ticagrelor) in these two patient populations after receiving 180mg or 90mg start-dose. Determination of plasma concentrations is done after protein precipitation, by using liquid chromatography with mass spectrometry detection. Measurements will be determined before intake (0h) and at 0,5; 1; 2; 4; 8; 24h and at day 4 +4h.7 The first 24h this will be a crushed tablet and 4 hours after the first intake at day 4 of therapy, this will be a non crushed tablet.
