Filter by:The aim of this observational study is twofold. The primary hypothesis being tested is that initial(first) high sensitivity Tn <5ng/l (limit of detection) combined with an ECG with no ischaemic changes is superior as an accelerated diagnostic tool/strategy compared to TIMI score (<2), GRACE <75 and HEART score ≤ 3. (Hs tn T- Roche elecsys HS tn T) and also against HS troponin at the 99th percentile (<15ng/l with nonischaemic changes)- again all scored with initial (first tn ) only. The second aim is to directly compare the three established methods of risk stratifying patients (predicting risk in suspected heart attacks) namely, the Global Registry of Acute Coronary Events (GRACE), Thrombolysis in Myocardial Infarction (TIMI) and HEART score in the era of high sensitivity troponins performs best.
The study design was composed of 2 parts, 2-way crossover and multiple-dose. There are having 2 groups in each part that have divided period 1 and period 2, and wash-out period is 16 days between periods. Each group is taking Telmisartan (80mg) and/or Atorvastatin (80mg) once a day for 6 days.
The ultimate goal of this project is to develop a risk score to identify patients with vulnerable coronary atherosclerotic plaques, who are prone to suffer acute coronary syndrome. Early identification of vulnerable plaques may have an enormous impact on public health through primary and secondary prevention of acute myocardial infarction. Investigators hypothesize that a risk score that incorporates non-invasive coronary CT imaging (calcium score and/or coronary CTA) in combination with clinical characteristics (classical risk prediction models) will improve the identification of patients who are at highest risk to suffer myocardial infarction or sudden cardiac death. The overall goal of the OPeRA project is to develop, implement and validate a novel risk assessment tool based on image markers and clinical characteristics to identify patients who are at increased risk to suffer myocardial infarction or sudden cardiac death.
The purpose of this pilot study is to evaluate the feasibility of the prophylactic administration of Factor VIII Inhibitor Bypass Activity (FEIBA) at termination of cardiopulmonary bypass (CPB) period. Specifically, the proposed study is designed to demonstrate the potential role of FEIBA administration in reducing the need for allogeneic transfusion to treat refractory coagulopathy in high risk patients.
Vascular inflammation, a central feature of atherosclerosis, participates in the initiation, perpetuation and instability of plaques. Multiple clinical trials of cholesterol lowering therapy with statins have demonstrated that reductions in atherosclerotic cardiovascular disease (CVD) events are associated with reductions in both LDL cholesterol (LDL-C) and the systemic inflammatory mediator C-reactive protein (CRP). The Cardiovascular Inflammation Reduction Trial (CIRT) investigates if an anti-inflammatory agent commonly used in rheumatoid arthritis (low dose methotrexate (LDM)) can reduce CV morbidity and mortality among patients with a prior myocardial infarction or angiographically demonstrated multivessel coronary artery disease (GCO#13-1467). In this ancillary CIRT imaging study, the investigators propose to use this well validated approach by non-invasive serial FDG-PET/CT imaging in a subset of patients enrolled in the main CIRT trial to directly visualize vascular inflammation. Once the subjects are enrolled in the main CIRT trial, baseline imaging will be done and follow up imaging will be done approximately 8 months after the baseline imaging. 18FDG-PET imaging data will be acquired, analyzed centrally and results incorporated into the main CIRT database. The investigators hypothesize that LDM treatment will result in a significant decrease in plaque inflammation as measured by 18-FDG-PET/CT after 8 months as compared to placebo.
The purpose of this trial are to pragmatically investigate whether participation in a comprehensive CR (i.e., exercise with education) program in a Latin American MIC results in better functional capacity, cardiovascular risk factor control, health behavior, disease-related knowledge, depressive symptoms and lower mortality when compared exercise only CR or wait list control.
The purpose of the proposed research study is to assess the effects of including greater amounts of minimally processed red meat (lean pork and beef) into a Mediterranean Diet on cardiometabolic and emotional well-being.
Evaluation of the add-on effect on endothelial dysfunction of treatment of periodontitis in patients with chronic periodontitis and severe obstructive sleep apnea treated by CPAP. Patients with and without chronic periodontitis will be treated by CPAP for 20 weeks. At V2 (10 weeks), endothelial dysfunction will be assessed by the Reactive Hyperemia- Peripheral Artery Tone index. The endothelial dysfunction of the patients will be also assessed at V3 (20 weeks) after periodontitis treatment for the group of patients with chronic periodontitis.
To determine the effects of ambient airpollution exposures on cardiovascular responses among healthy adults without cardiovascular disease.
To investigate possible physiologic interactions between the adrenal- and the parathyroid glands in patients with secondary hyperparathyroidism.
