Digital supine bicycle stress echocardiography: a new technique for evaluating coronary artery disease.
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...
متن کاملSupine bicycle versus post-treadmill exercise echocardiography in the detection of myocardial ischemia: a randomized single-blind crossover trial.
OBJECTIVES We sought to determine the comparative accuracy of supine bicycle exercise echocardiography (SBE) and posttreadmill exercise echocardiography (TME) in detecting myocardial ischemia in patients with known or suspected coronary artery disease (CAD). BACKGROUND Supine bicycle echocardiography and TME have been used for evaluation of CAD. However, the comparative accuracy of these moda...
متن کاملInstantaneous coronary collateral function during supine bicycle exercise.
AIMS The instantaneous response of the collateral circulation to isometric physical exercise in patients with non-occlusive coronary artery disease (CAD) is not known. METHODS AND RESULTS Thirty patients (age 59 +/- 9 years) undergoing percutaneous coronary intervention because of stable CAD were included in the study. Collateral function was determined before and during the last minute of a ...
متن کاملEffect of dynamic myocardial dyssynchrony on mitral regurgitation during supine bicycle exercise stress echocardiography in patients with idiopathic dilated cardiomyopathy and 'narrow' QRS.
AIMS Cardiac resynchronization therapy (CRT) has become an attractive therapeutic option for patients with end-stage heart failure (HF). Currently, patients are selected for CRT on ECG and on echocardiographic criteria analysed at rest. Whether the physical effort may further increase myocardial dyssynchrony is not fully established. The aim of the study was to test by the use of Doppler myocar...
متن کاملUltrasound contrast and real-time perfusion in conjunction with supine bicycle stress echocardiography for comprehensive evaluation of surgically corrected congenital heart disease.
AIMS We sought to evaluate the efficacy of ultrasound contrast (UC) and low mechanical index real-time perfusion (RTP) in the haemodynamic and anatomic assessment of repaired congenital heart disease (CHD) at rest and during supine bicycle stress echocardiography (BSE). METHODS AND RESULTS Patients with CHD (n = 51, median age 21.5 years) were prospectively studied. All had compromised image ...
