Filter by:The purpose of this study was to assess whether interpatient variability in the platelet response to clopidogrel is partly due to polymorphisms of the hepatic cytochrome P450 (CYP450)3A and of the clopidogrel-P2Y12 receptor genes.
Clopidogrel pre-treatment before planned percutaneous coronary intervention was proved to reduce periprocedural complications. However, the vast majority of patients in the current interventional cardiology practice do not undergo planned PCI, but rather "ad-hoc" PCI performed immediately after coronary angiography . Whether clopidogrel should be administered as pre-treatment to all patients undergoing elective CAG with the aim to ensure therapeutic levels at the time of possible ad-hoc PCI is not known.
The purpose of this study is to evaluate the prevalence and clinical predictors of subclinical coronary atherosclerosis and to validate the usefulness of coronary CT angiography as a screening tool in asymptomatic patients with type 2 diabetes mellitus.
The purpose of this study is to validate the usefulness of 64-slice multi-detecter computeted tomography as a screening tool in asymptomatic population.
The purpose of this study is to compare the difference of diagnostic efficiency between coronary CT angiography and myocardial perfusion single photon emission computerized tomography in asymptomatic patients with type 2 diabetes mellitus.
Rheumatoid arthritis (RA) is a symmetric, peripheral polyarthritis of uncertain etiology that can lead to joint deformity and destruction. However, the effects of RA are not confined simply to joint involvement. Virtually every organ system can be affected by RA if left untreated. Of particular note is RA’s affect on the cardiovascular system. RA patients have a reduced lifespan compared to the general population primarily due to an increased cardiovascular disease burden (1). Recently, RA has been linked to the development of preclinical atherosclerosis in the carotid arteries as measured by ultrasonography (2). Women with RA have also been shown to have an increased incidence of nonfatal myocardial infarctions (3). Despite these studies showing the effects of RA on the cardiovascular disease burden of those who are afflicted, no study to date has compared the number of cardiovascular events in a large RA patient population to a risk factor and age matched control group. Consequently it is the goal of this study to determine whether the cardiovascular event ratio in an RA patient cohort exceeds an age and risk factor matched cohort of non-RA patients. This study will also attempt to ascertain whether specific cardiovascular risk factors contribute to the cardiovascular morbidity and mortality associated with RA and if any standard cardiovascular medicines disproportionately contribute to patient outcome. Hypothesis: Given the increased cardiovascular disease burden associated with RA patients they are likely to suffer from a statistically significant increased risk of cardiovascular events when compared to an age and risk factor matched cohort.
Aim of the study is to show additional effects of the combined therapy of niacin and statins analyzing number and function of EPCs and other stem cell populations and adiponectin as well as hsCRP levels in patients with CAD.
To investigate the safety of nitrous oxide (N2O) anaesthesia in patients with risk factors for coronary artery disease undergoing major surgery.
The study hypothesis is that differential proteomic techniques can be used to discover new circulating biomarkers of coronary atherosclerosis in the blood of patients suffering from coronary artery disease (either stable or unstable) who will be compared to a group of patients without coronary artery disease
Aim: To investigate the quality of history taking by physician and computer-based system. Patients: 100 inpatients presenting at the RBK for the first time and treated in the departments of nephrology and cardiology. Methods: The information obtained by the computer based system is compared with the information acquired by conventional history taking. Study endpoint is the comparison of historical data organized according to the elements in a standard medical history on a patient-by-patient basis. Study procedure History taking is performed by physicians according to the guidelines of the RBK. Within 2 days thereafter the patient is interviewed with help of the CLEOS system with the support of a study nurse.
