Filter by:In this study the effect of the switch to rosuvastatin from another statin (fluvastatin, pravastatin, simvastatin, atorvastatin) was evaluated in high-risk patients with and without evident CHD and LDL-C ≥ 3.2 mmol/l. This was done in a large observational study (TARGET) representing daily practice. Primary end points analysis was the percentage of patients reaching the target of LDL-C < 3.2 mmol/l. Secondary outcomes were the changes of LDL-C, HDL-C, TC, Triglycerides (TG) and TC/HDL-C-ratio from baseline.
Options for coronary revascularization include stent implantation and coronary bypass surgery. Both modalities have their unique advantages and disadvantages in terms of clinical outcomes as well as financial impact on the medical system. We wish to investigate the late results of patients undergoing coronary revascularization, the need for re-hospitalization, re-intervention, patient satisfaction as well as the financial burden on the medical system. The study will be conducted by historical prospective review of hospital records in conjunction with records of the medical insurance companies ("HMO's").
The aim of the study is to assess the safety and efficacy of the Paclitaxel-eluting PTCA-balloon in the treatment of in-stent restenoses in native coronary arteries with reference diameters between 2.5 mm and 3.5 mm and ≤ 22 mm in length for procedural success and preservation of vessel patency in comparison to the Paclitaxel-eluting Taxus™ stent.
There is substantial, continuing, and unexplained rise in prescribing of proton pump inhibitors. It is unknown whether their use in practice has corresponded to their licensed indications. Although the indications for H2RA or PPI administration in the treatment of acid-related diseases and the prevention of gastric mucosal damage have been well defined in the medical literature, the perception of benefit from their use frequently tends to be extrapolated to all patients in general, leading to an excessive consumption of these drugs in general practice. To date, however, little has been published with regard to the overall use or misuse of these drugs in hospital populations in ischemic heart disease patients as a secondary prevention to Aspirin use. We will undertake a 6-months retrospective survey (about 1200 patients) to evaluate the use of acid-suppressive medications in the general internal medicine ward of Rambam Hospital. We will extract all records of prescribing of a proton pump inhibitor within Rambam Hospital computerized patients file program (Premetheuos) in period of half year, categorized and analyze them using statistical X2 test.
The purpose of this study is to demonstrate that Iodixanol 320 is associated with a lower incidence of contrast-induced nephropathy (CIN) when compared with hyperosmolar contrast medium Iomeprol 350 in patients with impaired renal function undergoing percutaneous coronary interventions (PCI).
The purpose of this study is to compare the BioMatrix Flex (Biolimus A9-Eluting) stent system with the Cypher SELECT (Sirolimus-Eluting) stent system in a non-inferiority trial.
Randomized nine months clinical comparison of implantation of Taxol eluting (Taxus Express) and Sirolimus eluting (Cypher Select) stents in non-selected patients with coronary artery disease.
Family history of early atherosclerotic disease in a first-degree relative [(FDR) sibling, parent or child] is an important risk factor for coronary artery and/or vascular disease. The risk increases ~ 2 - 7 times over that of general population. Increased thickness of the intima and media of carotid arterial wall, increased rate of plaque formation is an independent predictor of cardiovascular disease. Also it is shown that increased level of calcium deposition in the arterial wall is also associated with increased level of coronary artery narrowing. We will assess the occurrence and severity of abnormalities of intima media thickness (IMT) and/or plaque formation and increased calcium deposition in the coronary arteries and their relation to the well known traditional risk factors (plasma glucose, smoking, BMI, waist circumference, blood pressure, total cholesterol, low density lipoprotein, total cholesterol/high density lipoprotein ratio) and non-traditional risk factors (C-reactive protein, Lpa, homocysteine) in FDRs of index patients with early onset of heart or vascular disease and appropriate control population. Also to determine which of the above factor can assess IMT and Ca score better. This may help to reduce the cost of investigation, and to identify the population at high risk of developing cardiovascular disease, which may help the physicians to treat early on before cardiovascular complications occur. Also this may help to reduce the cost of invasive tests, hospital admissions and medical costs overall by reducing the morbidity and mortality.
Silent ischemia has been shown to negatively affect prognosis in patients after myocardial infarction. However, long-term outcome data in totally asymptomatic patients is missing and it is unknown whether angioplasty in addition to secondary preventive measures is superior to antiischemic drug therapy in these patients. Therefore, the SWISSI 2 study was started 15 years ago with the aim of comparing the effects of angioplasty with medical therapy on long-term outcome in patients with recent myocardial infarction and silent ischemia.
Rationale: Patients with severe ventricular dysfunction and coronary disease have high morbidity and mortality. They may benefit from revascularization, but have significant peri-operative morbidity and mortality. Positron emission tomography (PET) imaging with F-18-fluorodeoxyglucose (FDG) can detect viable myocardium that may recover from revascularization in such patients. It is unclear whether use of FDG PET in this population is improves outcome or is cost-effective. Objectives: The principal aim is to determine whether FDG PET-guided therapy is effective versus standard care. Secondary objectives are to determine whether FDG PET-guided therapy improves LV function, quality of life and is good value for money versus standard care.
