Filter by:Cholesterol is the precursor of glucocorticoids, mineralocorticoids and sex steroids. Both adrenal and non-adrenal (ovarian + testicular) all steroid hormones are primarily synthesized using the LDL–cholesterol in the circulation. Additionally there is ‘de novo’ cholesterol synthesis in both the adrenals and gonads controlled by the HMG-CoA reductase enzyme. A third pathway is the use of circulatory HDL–cholesterol by the adrenal and gonadal tissues for the synthesis of steroids. Since statins both decrease circulatory LDL and inhibit de novo cholesterol synthesis, they are likely to affect the synthesis of steroid hormones. In this study we aim to investigate the effects of lowering LDL levels below 70 mg/dL on steroid hormone synthesis.
The purpose of this study is to validate the usefulness of 64-slice multi-detecter computeted tomography as a screening tool in asymptomatic population.
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.
The purpose of the present study is to provide the first in-human safety and efficacy evaluations of systemic oral anti-proliferative Everolimus therapy compared to placebo in patients treated by bare metal stents for significant coronary artery disease. The aim is to reduce Major Adverse Cardiac Events (MACEs) including death, coronary artery bypass grafting (CABG) to the target vessel, Q-wave and non-Q-wave myocardial infarction, and target lesion revascularization within the first 6 months after intervention. Additionally safety and tolerability of Everolimus at the selected dose in this patient population will be analyzed.
The purpose of this study is to determine the effect of 6R-BH4 on vascular function in patients with coronary artery disease. We hypothesize that 6R-BH4 will improve vascular function in these patients.
This is a prospective double blind trial of intraoperative transmyocardial bone marrow−derived mesenchymal cell transplantation vs placebo in patients with low left ventricular ejection fraction scheduled to coronary bypass operation.
The aim of this study is to identify genetic loci,or gene variations contributing to inflammation and to the development of CHD. We will compare coronary angiogram results to genetic findings within coronary artery disease patients and in patients with normal coronaries.
The objective of this study is to evaluate an antibiotic therapy called Rifalazil to determine its effect on hardening of the carotid arteries.
Coronary artery disease (CAD) is a silent killer that may go undetected for years. It is the leading cause of death with no limitation to geographic boundaries accounting to about 16.7 million deaths world wide. Different studies have shown that South Asians populations are more prone to CAD where it is emerging as an epidemic. According to a study conducted in Karachi it is estimated that the overall prevalence of cardiovascular diseases in Pakistan is 26.9% with 23.7% in men and 30.0% in women. However tools for measuring CAD have not being adequately validated. This study is designed to develop screening tools and to determine test characteristics of Rose Questionnaire and Minnesota Coded ECG alone and in combination for diagnosis of CAD, using MPI as gold standard in Pakistan.
Restenosis requiring reintervention is still a limitation of percutaneous coronary angioplasty. Despite the use of Drug eluting stent (DES), the rate of restenosis remains 7% to 16% in diabetic patients, making it a challenging problem in interventional cardiology. Still, in clinical trials, most of these attempts did not successfully limit neointimal formation after coronary stenting. Thiazolidinediones (TZDs), like pioglitazone (pio) or rosiglitazone, are a novel class of oral antidiabetic agents currently used to treat patients with type 2 diabetes mellitus. These agents increase insulin sensitivity and, as such, have favorable effects on blood glucose levels and the lipid profile in treated patients. Beyond their metabolic action, TZDs have been shown to exhibit antiinflammatory and antiatherogenic effects in vascular cells in vitro and to limit lesion development in various animal models of arteriosclerosis. Moreover, TZDs inhibit VSMC proliferation and migration, 2 critical processes in neointimal formation after coronary stenting. Data from rodent models suggest that TZDs limit intimal proliferation after vascular injury, and in clinical studies with type 2 diabetic coronary artery disease (CAD) patients, TZDs have been shown to reduce neointimal formation as well as restenosis after coronary stent implantation. Still, it remains unclear to what extend these effects depend on the metabolic action of these drugs and what might mainly be due to the improvement in glycemic control. Recently a few reports on prevention of restenosis in type 2 diabetic patients (T2DM) with the use of TZDs as been published. All of them uses BMS as endoprosthetic devices. None of these evaluated the use of TZDs in combination with DES. Aim of the study is to evaluate the efficacy of pioglitazone in prevention of in-stent restenosis after successful implantation of a sirolimus-eluting coronary stent for treatment of de-novo "complex" coronary vessel disease in patients with T2DM and stable coronary artery disease. Study primary end-point are late-loss at 9 months.Secondary end-point include binary restenosis MACE at 1, 9 and 12 month, stent thrombosis at 12 months.
