background: diagnosis of coronary artery disease (cad) in patients with left bundle branch block (lbbb) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ecg). this diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. the aim of this study was to ass...

OBJECTIVES The purpose of our study was to conduct an evidence-based evaluation of stress cardiac magnetic resonance imaging (MRI) in the diagnosis of coronary artery disease (CAD). BACKGROUND Stress cardiac MRI has recently emerged as a noninvasive method in the detection of CAD, with 2 main techniques in use: 1) perfusion imaging; and 2) stress-induced wall motion abnormalities imaging. M...

background: pneumocystis carinii is one of opportunistic organisms especially in immuno-compromised patients. for years, diagnosis of pneumocystis pneumonia (pcp) has relied on microscopic visualization of organism in specimens obtained from the lung either by bronchoalveolar lavage (bal) or by induction of sputum, but failed to provide efficient diagnosis. the aim of this study was to compare ...

The incidence of significant obesity is rising across the globe. These patients often have a clustering of cardiovascular risk factors and are frequently referred for noninvasive cardiac imaging tests. Stress echocardiography (SE) is widely used for assessment of patients with known or suspected coronary artery disease (CAD), but its clinical utility in morbidly obese patients (in whom image qu...

OBJECTIVE To determine if bradycardia during hyperbaric exposure is accompanied by a negative influence on myocardial contractility. METHODS Accelerometer-based registration of myocardial compression waves with Seismocardiography (SCG) for noninvasive contractility monitoring. Comparative pulmonary artery (PA) catheter study (9 ICU-patients, mean = 67ys) with ejection-fraction (EF) equivalent...
