Filter by:SPECT is currently the dominant clinical test for diagnostic and prognostic purposes as well as therapeutic decision-making. Given the shortage of nuclear reactor-produced Tc, advancing the use of non-isotope based imaging modalities has the potential to change the standard of care for patients with CAD as each one of these technics (CMR, CT, Stress echocardiography) has its own distinct potential advantages over SPECT.
Our hypothesis is that quantitative 3D analysis of cardiac CT images obtained during vasodilator stress can accurately identify patients presenting at the emergency department with acute chest pain due to underlying hemodynamically significant coronary stenosis, aid in the identification of individuals most likely to benefit from revascularization, and thus improve the ability to predict patient outcomes. Our goals are: 1. to test the above hypothesis by comparing stress MDCT perfusion data with invasive fractional flow reserve (FFR) data in patients with significant stenosis who undergo ICA; 2. to determine the added value of MDCT perfusion as an adjunct to CTCA for predicting patient outcomes.
Patients with stable coronary disease when undergoing percutaneous coronary intervention may present periprocedural myocardial infarction defined at present as a creatine kinase-myocardial isoenzyme (CK-MB) elevation 3 times upper limit of normal, as a cut off for periprocedural myocardial infarction after PCI. Although percutaneous coronary intervention is associated with low rates of complications, periprocedural myocardial infarction has been touted as a negative factor in long-term clinical results . Several clinical, anatomical and technical associate to the occurrence of this event . Although randomized controlled trials and systematic reviews to statin pre intervention have targeted the administration of high-dose statin is recommended before surgery to reduce the risk of periprocedural myocardial infarction, there is no information on the impact of the maximum concentration plasma of statin at the time of percutaneous coronary intervention in stable patients on chronic statin use in preventing periprocedural myocardial infarction or the elevation of cardiac enzymes . The anti-ischemic effect of statins in percutaneous coronary intervention was mainly determined in statin -naïve patients or in patients with acute coronary syndromes . In this work , we studied the impact of the peak plasma concentration of statin at the time of percutaneous coronary intervention was studied through prospective randomized single center in stable patients with chronic statin divided into two groups . In the group (1) Experimental (n = 268 ) was administered at a dose of 40 mg rosuvastatin between one and six hours before surgery and group (2) control without rosuvastatin (n = 268). This range 1 to 6 hours is the time at the peak concentration of rosuvastatin in the blood after oral ingestion. The primary objective was to assess the incidence of periprocedural myocardial infarction by creatine kinase above three times upper normal limit in hospital period and as a secondary objective to analyze the elevation of any amount of creatine kinase on the baseline.
This registration study aims to investigate the associations of the pharmacogenetic and pharmacokinetic factors with clopidogrel low response and clinical outcome in patients with coronary artery disease, and provide new pharmacogenetic and pharmacokinetic targets for the individualized anti-platelet treatment.
Prasugrel and ticagrelor were both associated with a significant reduction in the risk of MACE in patients undergoing PCI for an ACS, mostly through a reduced stent thrombosis. The 1-year relative risk reduction (RRR) of definite of probable stent thrombosis in patients receiving a DES were fairly different in TRITON-TIMI 38 and PLATO trials. The incidence of "biologically active" stent (DES or BVS) thrombosis is largely variable according to different lesion settings. We aim to verify the translation of the postulated different reduction in thrombosis rate among various P2Y12 inhibitors (clopidogrel, prasugrel and ticagrelor) in a high-risk setting such as the PCI with DES or BVS in CTO and bifurcating lesions.
The purpose of this study is to assess the safety and effectiveness of the SYNERGY™ Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) ≤ 34 mm in length (by visual estimate) in native coronary arteries ≥2.25 mm to ≤4.0 mm in diameter (by visual estimate)
The purpose of this study is to evaluate the supplementation with extra virgin of coconut oil combined with a nutritional counseling in reducing anthropometry and improves the lipid profile in patients with chronic coronary disease.
The purpose of the study is to evaluate non-inferiority of oral anticoagulant (OAC) monotherapy to OAC plus single antiplatelet therapy (APT) in patients with atrial fibrillation (AF) and prior (>12 months) coronary stenting.
The purpose of this study is evaluate the efficacy of perioperative continuous lumbar plexus block in reducing the risk of cardiac ischemic events of elderly patients undergoing surgery for hip fractures, expressed as a reduction of ischemic events per subject.
BIOSOLVE-II is a prospective, international, multicenter, First in Man study. The purpose of this study is to assess the safety and clinical performance of the drug eluting absorbable metal scaffold (DREAMS 2nd Generation).
