BACKGROUND The purpose of this study was to evaluate the effectiveness of a standardized preoperative cardiac assessment in reducing the rate of perioperative cardiac complications in patients undergoing aortic surgery, paying particular attention to the analysis of the factors affecting perioperative cardiac outcomes. METHODS Between January 2005 and August 2008, a total of 531 elective inte...
IntRoductIon Coronary computed tomographic angiography (CCTA) as a noninvasive diagnostic technique for the evaluation of coronary anatomy is widely used clinically. Its advantages include high sensitivity and specificity for the diagnosis of present of coronary artery lesions and lesion characteristics, short scan time, low patient radiation exposure, and acceptable to patients. The sensitivit...
BACKGROUND Although risk stratification is an important goal of cardiac noninvasive tests (NITs), few contemporary data exist on the prognostic value of different NITs according to patient sex. OBJECTIVES The goal of this study was to compare the results and prognostic information derived from anatomic versus stress testing in stable men and women with suspected coronary artery disease. MET...
Background and Objective:Accurate diagnosis of CAD using noninvasive procedures is of great importance. The aim of the study is to assess diagnostic accuracy of myocardial perfusion imaging and compare it with exercise stress test in order to decipher a more accurate and cost-effective method for CAD detection. Materials and Methods:Of 430 consecutive patients suspected with CAD, 104 performed...
We developed a simple, noninvasive artificial insemination technique to study epigenetic germline inheritance in mice. This technique avoids interfering factors introduced by superovulation, surgery, in vitro culture or mating that can confound the transmission of acquired epigenetic information through the germline. Using a stress model, we demonstrate that our method is suited to test the cau...
Stress cine function and vasodilating stress perfusion are commonly used approaches for the evaluation of ischemic heart disease. Both imaging approaches, using either stress echocardiography or stress nuclear scintigraphy, have stood the test of time as highly accurate in diagnosing coronary artery stenosis and as prognostic tools in patients with symptoms suspicious of myocardial ischemia.1,2...
BACKGROUND The appropriate roles for several diagnostic tests for coronary disease are uncertain. OBJECTIVE To evaluate the cost-effectiveness of alternative approaches to diagnosis of coronary disease. DESIGN Meta-analysis of the accuracy of alternative diagnostic tests plus decision analysis to assess the health outcomes and costs of alternative diagnostic strategies for patients at inter...
