Filter by:In this prospective, randomized, clinical trial, we have investigated the effects of ketamine-based and remifentanil-based anesthetic protocol on perioperative serum cystatin-c levels, and creatinine and/or cystatin-c based eGFR equations in terms of acute kidney injury in CABG surgery.This study was approved by the Ethics Committee of Hospital and all patients were informed and gave written consent. Patients scheduled for elective CABG with cardiopulmonary bypass. Patients were randomly allocated to anesthesia with remifentanil-propofol-midazolam (RPM) group or ketamine-propofol-midazolam (KPM) group. Blood samples were obtained before induction of anesthesia (baseline), at the end of the operation, and postoperative days 1, 2, and 4.
meriT-V is a Prospective,active control open lable clinical trial to compare safety & efficacy of BioMime Sirolimus stent Vs. Xience family of Everolimus stent by random assignment for treatment of coronary artery disease at multiple multinational centres.
Heart attacks are most commonly caused by rupture of fatty deposits (plaques) within the wall of heart blood vessels. It appears that this process can also frequently occur without causing any symptoms and these events likely explain the development of narrowing within the heart arteries which can subsequently produce symptoms of angina (chest pain). Previous research has shown a specialised scanner known as a PET (positron emission tomography) scan can identify these recently ruptured plaques in patients without symptoms of a heart attack and these patients have changes on a blood test (troponin) which suggest that they are at higher risk of having a heart attack in the future. This study aims to identify these patients using the PET scan and then see if the markers of increased heart attack risk can be reduced by the use of a blood thinning medication (ticagrelor) which is already a well recognised treatment for people who have suffered a recent heart attack.
The purpose of the study is to identify a sub-group of diabetic patients at higher risk of progression of coronary disease and also more likely to suffer from heart attack/angina and heart failure. The total number of patients to be recruited in this study will be 250 with type-2 diabetes but no known heart disease. These patients will have an objective measure of the function of the lining of the arteries, CT scan of the arteries of the heart and an ultrasound scan of the heart and arteries of the neck done at baseline along with blood tests for identification new markers of malfunction of the lining and inflammation of the arteries. Patients will be followed up at 18 months. During the follow-up visit, in addition to the blood tests, the CT scan of the heart arteries and ultrasound of the heart and arteries of the neck will be repeated to assess progression of the non-calcified, calcified and mixed plaques in the coronary arteries.
The study should enrol 50 patients with stable coronary artery disease scheduled for elective percutaneous coronary intervention of single, de novo lesion of native coronary artery. Patients will be randomized to orally given trimetazidine on top of standard medical therapy for stable coronary artery disease versus standard therapy only. The randomization will begin 48 hrs before intervention. Index of microcirculatory resistance (IMR) will be measured by thermodilution method using coronary pressure and temperature wire before and after stent implantation. Echocardiography will be performed before intervention and within 30 minutes after intervention. Patients will be followed clinically for a period of one year.
The purpose of the present study was to test the hypothesis that patients with coronary artery disease with lower aerobic fitness exhibit greater responsiveness on improving ventilatory efficiency after aerobic exercise training.
Microvascular dysfunction is a key determinant of pathogenesis and outcome in patients suffering an acute myocardial infarction. The investigators hypothesise that treatment with intracoronary abciximab, a potent anti platelet agent, at the time of coronary stent insertion, will improve microvascular function.
The purpose of this study is to compare standard therapy (risk factor control, life style modification) versus standard therapy plus low-dose rosuvastatin therapy (5mg/day) on progression of coronary atherosclerosis in statin naive individuals who have mild CAD (nonobstructive coronary atherosclerotic plaques) and normal LDL (low-density lipoprotein) cholesterol levels(〈130mg/dl).
The DTS.DE registry is an initiative for the collection of high quality process and historical data of implantations with the COMBO Dual Therapy Stent in Germany. DTS.DE was designed as a national, non- randomized, prospective, multicenter registry without a comparison group. The responsible Steering Committee is of the opinion that the Combo stent qualifies for further documentation of treatment results in the form of a German registry, based the CE certification of the COMBO Dual Therapy stent in 2013 and its clinical and scientific investigation in the context of the REMEDEE study program, as well as company independent externally initiated studies with the COMBO Dual Therapy Stent. It is expected that by mid- 2015, at least 1,000 patients will be enrolled and documented in the DTS.DE registry with the COMBO Dual Therapy Stent. A clinical follow-up is performed after 6 weeks and 12 months.
Low medication adherence in patients with coronary heart disease increases mortality. This study investigates if an intervention of medication review and counselling can improve patients' medication adherence and treatment results.
