Detection of coronary artery stenosis by dipyridamole radionuclide ventriculography.

Radionuclide ventriculography in coronary artery disease.

Exercise first-pass radionuclide ventriculography in detection of coronary artery disease.

Thirty-four patients with coronary artery disease were exercised on a bicycle ergometer until they developed angina. There was a highly significant fall in ejection fraction from a mean of 61 1 to 52-9 which was more pronounced in the group with three vessel coronary artery disease. A coronary index was computed which took into account the extent and distribution of coronary artery lesions. Tho...

surgery: etiologic classification by radionuclide ventriculography

Early after open heart surgery, cardiac shock due to tamponade is easily misdiagnosed as ventricular dysfunction. The distinction is critical to successful therapy. We assessed the utility of 99mTc-red blood cell, gated equilibrium radionuclide ventriculography in 50 patients with early postoperative cardiac shock after historical, clinical, and invasive hemodynamic evaluation failed to identif...

The acute hemodynamic effects of intravenous verapamil in coronary artery disease. Assessment by equilibrium-gated radionuclide ventriculography.

The acute hemodynamic effects of an i.v. bolus of verapamil, 0.1 mg/kg or 0.06-0.075 mg/kg, were examined by serial radionuclide studies in 46 patients with coronary artery disease. In 20 patients with ejection fractions (EFs) greater than 35% (group 1A), verapamil, 0.1 mg/kg given over 1-11/2 minutes, had a biphasic effect: first, a transient decrease in EF accompanied by increased left ventri...

diagnostic efficacy of vessel specific coronary calcium score in detection of coronary artery stenosis

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...
