Dobutamine stress echocardiography has significant advantages in our country due to its wide availability, portability, low cost and safety.This study was conducted with the aim assess myocardial viability by Stress Echocardiography (DSE) before PCI total occlusion of coronary artery.This confirms that a biphasic response dobutamine is highly predictive postoperative recovery regional contracti...

BACKGROUND The optimal imaging strategy for patients with stable chest pain is uncertain. OBJECTIVE To determine the cost-effectiveness of different imaging strategies for patients with stable chest pain. DESIGN Microsimulation state-transition model. DATA SOURCES Published literature. TARGET POPULATION 60-year-old patients with a low to intermediate probability of coronary artery disea...

Exercise testing has an established role in the evaluation of patients with valvular heart disease and can aid clinical decision making. Because symptoms may develop slowly and indolently in chronic valve diseases and are often not recognized by patients and their physicians, the symptomatic, blood pressure, and electrocardiographic responses to exercise can help identify patients who would ben...

The coming decades will provide dramatic new challenges for those of us in clinical cardiology. We will be challenged to provide more accurate and more clinically pertinent information in a more cost-effective manner for patients ranging in age from their teens to their nineties. The spectrum of diseases wiIl range from congenital to valvular to ischemic, with the latter predominating. As such,...

BACKGROUND Ischemic heart disease (IHD) causes more deaths, disability and economic loss in developed and developing countries than any other disease. Our country belongs to the group of countries in transition, and it has seen a continuous growth in mortality and morbidity rates caused by cardiovascular diseases. An early, accurate and fast diagnosis of the myocardial ischemia is the main step...

UNLABELLED The assessment of regional ventricular function is dependent on good endocardial definition. Suboptimal images can be converted to diagnostic recordings in the majority of patients by contrast agents, which have become an indispensable aid in rest and stress echocardiography. In particular for stress echocardiography image quality is essential and contrast administration is of great ...

Dear Editor, Dobutamine stress echocardiography is one of the several noninvasive methods for detection of coronary artery disease (1). New regional wall motion abnormalities have been reported in dobutamine stress echocardiograpghy after intravenous beta blocker administration (2, 3) Thus, this method has been recommended for increasing the test sensitivity (4). The sensitivity, specificity, a...

OBJECTIVES The objective of this study was to determine the accuracy of digital supine bicycle stress echocardiography, a new technique for evaluating coronary artery disease during peak exercise. BACKGROUND Prior stress echocardiographic techniques have not utilized peak exercise imaging to determine the extent and location of coronary artery disease. METHODS Two-hundred twenty-two patient...
