Diagnostic Performance and Prognostic Ability of the QFR
Ischemic Heart DiseaseThe primary technical endpoint was the diagnostic performance of the QFR against the FFR. The primary clinical endpoint was target vessel failure (TVF) between two groups distributed by a QFR cut-off value of 0.8
CD16+ Monocytes in Coronary Heart Disease (CHD)
Coronary Heart DiseaseMonocytes may be separated into phenotypically and functionally distinct cell types by the presence or absence of the lipopolysaccharide receptor CD14 and the Fcγ-receptor CD16. The investigators hypothesize that the total numbers of CD16+ monocytes are significantly related to cardiovascular outcome in patients with angiographically proven coronary heart disease.

Prospective Study to Assess DES Re-endothelization in BMS Restenosis and De-novo Lesions
Stable Coronary Artery DiseaseSilent Myocardial Ischemia4 moreThe hypothesis of this study is that strut coverage occurs earlier when a DES is implanted to treat a BMS restenosis compared with atherosclerotic de-novo lesion. This hypothesis is supported by two different observations: first, when a DES is implanted to treat a BMS restenosis, stent struts are deployed and drugs are eluted on a soft tissue mostly characterized by extracellular matrix with a regular surface. In this case stent malposition is less likely to occur compared to atherosclerotic lesion whose surface is often more irregular and rich in calcium. Second, patients who develop in-stent restenosis after BMS implantation are likely to show a more pronounced neointima hyperplasia and, when a DES is implanted to treat restenosis, reendothelialization is likely to occur earlier. If this hypothesis was verified, duration of dual antiplatelet therapy could be shortened after DES implantation on BMS restenosis with a clinical advantage in terms of bleeding risk. Furthermore, a higher bleeding risk is often a reason for choosing a BMS instead of a DES; thus, patients presenting with BMS restenosis are likely to have a higher bleeding risk and to benefit from a shorter period of dual antiplatelet therapy.

Cardiac Magnetic Resonance Utilities in the Evaluation of Ischemic Heart Disease
Myocardial IschemiaThe purpose of this study is to evaluate CARDIAC MAGNETIC RESONANCE UTILITIES IN THE ISCHEMIC HEART DISEASE as topographical correlation between ischemic territory injury and coronary angiography.
Aspirin Responsiveness in Women With Coronary Artery Disease
CADThe purpose of this study is to measure the percentage of women with known Coronary Artery Disease (CAD) who are hyporesponsive to low dose (81 mg) aspirin.
Study of Coronary Heart Disease (CHD) & Heart Failure (HF) Risk in Prostate Cancer Patients, Taking...
Prostate CancerA retrospective cohort study performed in the GPRD,UK. All patients with incident prostate cancer identified between 1 Jan 1999 and 31 Dec 2005 and a frequency-matched cohort of the general population will be followed- up for two outcomes; CHD including acute myocardial infarction or death from coronary heart disease and HF until Dec 31, 2006. Outcomes will be validated through requests to primary care physicians. Incidence rate´ratios of CHD and HF in the two cohorts will be calculated. In the cohort of prostate cancer the relative risk of CHD and HF associated with the use of bicalutamide compared to non-use will be estimated.
An Observational Study of Cholesterol in Coronary Arteries
Myocardial InfarctionAngina2 moreIn April 2008, a coronary catheter based imaging system, LipiScan, was cleared by the FDA for use in detecting lipid core containing containing plaques of interest (LCP). These plaques are rich in cholesterol. The way that cholesterol and other lipids deposit with the coronary artery is unique to each patient. This study is an organized attempt to observe the LCP and the variety of ways that it presents in patients as detected by this recently approved device. This information will be used for physician training and to observe the behavior of the LCP in response to no therapy and currently approved therapies. The purpose of this project is further medical knowledge of the LCP and its treatment.
Associations Between Depression and Cardiovascular Disease - a Study of Patients With Late Onset...
DepressionMajor Depressive Disorder2 moreStudies show that depression is a risk factor for the development of coronary artery disease (CAD). Furthermore there is an increased occurrence of depression in patients with CAD. Among other mechanisms atherosclerosis is believed to play a central role regarding these notable associations between depression and CAD. Moreover, patients with late onset major depression have an increased number of small lesions found in the white matter of the brain, the so-called white matter lesions. The main goal of this project is to examine if CAD is associated with depression and/or white matter lesions. CAD is evaluated using coronary CT angiography. Depression is evaluated using a semi-structured diagnostic interview. White matter lesions are quantified using cerebral magnetic resonance.
