Celecoxib, Ibuprofen and the Antiplatelet Effect of Aspirin
Ischemic Heart DiseaseOsteoarthritisStudy design: Single center, placebo-controlled, double blind, parallel groups. To evaluate the potential interaction between aspirin and ibuprofen or celecoxib in patients with osteoarthritis (OA) and documented stable ischemic heart disease, a total of 24 patients chronically treated with aspirin will be randomly assigned to one of the 3 treatment groups: 1) celecoxib 200 mg bid; 2) ibuprofen 600 mg tid; 3) placebo.
Percentage of Secondary Prevention Patients Treated to Their LDL-C Targets
HyperlipidemiasAtherosclerosis4 moreA cholesterol/lipid profile screening project of high risk patients with hyperlipidaemia (secondary prevention) who already receive cholesterol-lowering therapy. Lipid profile and rate of patients who are treated to target (which is <100mg/dl for patients with high risk and <70mg/dl for patients at very high risk) are screened (hospital-based specialists). The doctors therapy decisions after the screening and possible reasons for these decisions will be documented. Our aim is to evaluate dosing habits, to evaluate how many patients are treated to their LDL-C target and to underline the importance of treating patients to their cholesterol targets.
Desflurane Versus Propofol Anesthesia for Off-Pump CABG
Coronary Artery DiseaseThe purpose of this study is to prove if anesthesia maintained with the inhaled volatile anesthetic desflurane is superior to the intravenously applied propofol anesthesia in off-pump coronary artery bypass grafting (OP-CABG) surgery as measured by following parameters: hemodynamic parameters during and after the operation, pulmonary gas exchange, need for mechanical ventilation and for ICU and intrahospital stay, release of heart muscle injury markers in response to surgery and intraoperative ischaemia, inflammatory response to the operation. We suspect that insufflation anesthesia with desflurane may be superior to intravenous anesthesia with propofol.
Symptom Management Intervention in Elderly Coronary Artery Bypass Patients
Coronary Artery DiseaseThe major purpose of this experimental study is to test the effects of the symptom management home care nursing intervention (SMHCNI) on recovery outcomes of elderly CABG patients, using a randomized, two group (n=284) repeated measures design with measurements at discharge, at 3 and 6 weeks, and 3 and 6 months postoperatively. One group will receive the intervention and routine care (RC) and the other group will receive RC only. The major aim will be to determine if the intervention group will demonstrate: better physiological functioning (decreased symptom interference on physical functioning; better scores on the SF36 subscales: physical, role-physical and vitality, and increased activity and exercise energy expenditure); better psychosocial functioning (decreased symptom interference on enjoyment of life; and better SF36 subscales; role-emotional, social, mental, and vitality); and fewer postoperative problems (e.g. infections, fluid in lungs, heart rate rhythm problems). Additional outcomes for secondary aims are: lower levels of health care utilization (HCU) (i.e., fewer number of visits to health care providers, fewer number of emergency department visits, fewer number of home health visits, fewer rehospitalizations); and higher patient satisfaction (with level of functioning and care received). In addition this study will examine the potential effects of mediating (evaluation of symptoms, and perceived self-efficacy), and moderating variables (participation in cardiac rehabilitation) with the intervention on outcomes identified.
Effect of Creatine and L-Arginine on Endothelial Function
Coronary Artery DiseaseThe study is a double blind 2x2 factorial study. Patients with coronary disease will be randomly be assigned to L-arginine (9 g/day), creatine 21 g/d, both, or neither dietary supplement. The function of the endothelium will be tested using ultrasound before and after each treatment. These studies will help us understand why the endothelium is abnormal in patients with coronary artery disease and how L-arginine is acting on endothelial function.
Endothelial Dysfunction in Subjects With History of Premature Coronary Artery Disease
Coronary Heart DiseaseThe aim of this prospective study is to investigate the prevalence of endothelial dysfunction in subjects with family history of premature coronary heart disease. At the same time, the effect of atorvastatin in treating subclinical endothelial dysfunction in those patients will be evaluated.
Effect of Ile-Pro-Pro (IPP) on Endothelial Function in Patients With Coronary Artery Disease
Coronary Artery DiseaseThis study will investigate whether the lacto-tripeptide Ile-Pro-Pro (IPP) improves the function of the endothelium in patients with coronary artery disease. The study has a crossover design. Participants will be treated with a protein hydrolysate rich in IPP for 12 weeks and placebo for 12 weeks with a four-week rest period between treatment periods. The investigators will use ultrasound to test the function of the endothelium in the brachial artery before, after 6 weeks, and after 12 weeks of each treatment. Blood will be collected before and after each treatment. The investigators hypothesize that IPP will improve endothelial function.
Physicians International Coronary Computed Tomography Angiography (CCTA) Utilization Registry
Coronary Artery DiseaseThis protocol describes an observational study whose goal is to collect de-identified Coronary CT Angiography (CCTA) acquisition factors and interpretations (findings) from several hundred U.S. and international imaging facilities. The study uses an electronic data capture tool to collect de-identified CCTA utilization parameters and clinical findings in order to create a multi-center registry. This registry will be used for scientific analysis and publication of pertinent medical trends such as CT utilization, radiation dose, and common cardiovascular findings. The registry will be used to determine areas of interest for future randomized controlled trials. All data will be collected with patient identifiers removed and in complete accordance with HIPAA regulations. All data will be analyzed in aggregate, thus further minimizing the risk of patient confidentiality violations.
Study of the Effect of Inhaled Anesthetics on Diastolic Heart Function Using a Doppler-derived Efficiency...
Diastolic DysfunctionCoronary Artery Disease1 moreThe purpose of this study is to determine the effect of inhaled anesthetic drugs upon diastolic heart function (heart suction and filling performance) in patients who are undergoing coronary bypass surgery.
Evaluation of Effectiveness and Safety of BIOMATRIX Stent (IRIS-BIOMATRIX)
Coronary Artery DiseaseThe objective of this study is to evaluate effectiveness and safety of BioMatrix stent in the "real world" daily practice as compared with first-generation drug-eluting stents (sirolimus- or paclitaxel-eluting stents).
