Filter by:Despite immediate symptomatic success after coronary bypass surgery in patients with coronary artery disease, this effect is not sustained over time since risk factors for coronary artery disease are still in place. The role of secondary prevention becomes increasingly important as it can potentially decrease or eliminate the need for another intervention in these high risk subjects. This project seeks to evaluate the effect of emphasizing secondary prevention measures in this patient population during hospital admission and through six months post-discharge.
The primary objective of this study is to test that endocardial stem cells implantation in patients who have CAD, low ejection fraction and signs of HF without possibility of CABG and PCI or despite on previous revascularization improves long-term survival compared to MED alone
The purpose of this study is to assess the safety of performing fractional flow reserve (FFR) of the myocardium without using anticoagulation by performing a retrospective review of 100 consecutive patients who have undergone this procedure during diagnostic catheterization.
The purpose of this study is to collect and analyze additional information about the safety and effectiveness of the Presillion™ Stent System in the treatment of de novo stenotic lesions in native coronary arteries.
The purpose of the study is to determine, whether the resistance to clopidogrel could be affected by higher doses of this drug, or by replacement of clopidogrel with another ADP-antagonist ticlopidine.
To exam the feasibility and accuracy of RTPE during vasodilator stress with 400micrograms of the A2A Receptor agonist Regadenoson for detection of significant coronary artery disease (CAD) in patients scheduled to undergo coronary angiography. Sensitivity, specificity , and accuracy of perfusion and wall motion analysis to identify a coronary stenosis> 50% in diameter by quantitive angiography will be analyzed
High-dose dobutamine/atropine stress cardiac magnetic resonance imaging (DS-MRI) has been incorporated in daily clinical practice for the detection of ischemic heart disease. Thus, wall motion abnormalities (WMA) during stress, precede the development of ST-segment depression on ECG and of anginal symptoms and aid in the detection of anatomically significant coronary artery disease (CAD). DS-MRI offers the possibility to integrate myocardial perfusion and wall motion analysis in a single examination. In this regard, recent data suggest that the assessment of myocardial wall motion and perfusion during a single session may enhance the sensitivity of the technique for the diagnosis of CAD. However, to date limited data is available on the prognostic value of high-dose DS-MRI in large patient cohorts, treated according to current guidelines. Assessment of long-term outcome of DS-MRI is important because this test may identify both high-risk patients, who would benefit from invasive diagnostic and therapy, and lower-risk patients in whom additional procedures and intensive medical follow-up are not required. In the present study we aim to determine the value of wall motion and perfusion assessment during high-dose dobutamine/atropine MRI in predicting cardiac events. In addition, the incremental value of the MR-stress testing results was assessed (inducible wall motion, perfusion abnormalities and the combination of both) after the consideration of traditional clinical risk factors and baseline ejection fraction.
This study was to determine whether ranolazine was effective in the treatment of neuropathic pain in patients with coronary artery disease. Eligibility required neurological examination by the study doctor and assessment of the patient's pain. Eligible participants were randomized to receive blinded study medication for a total of 12 weeks.
In 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.
The purpose of the study is to determine whether the excretion of renal water- and salt-channels in the urine reflects the handling of water and salt in the kidneys, and whether the excretion can be used to monitor and/or predict the effects of treatment of certain heart or lung diseases.
