متن کاملFollow-up technetium-99m stannous pyrophosphate myocardial scintigrams after acute myocardial infarction.
Technetium-99m stannous pyrophosphate (99mTc-PYP) myocardial scintigrams were obtained in 68 patients during acute myocardial infarction (AMI) and at follow-up 15.9 +/- 8.8 weeks later. All patients with AMI had a positive scintigram (2+ or greater); only one of 46 control patients (2%) had a positive (2+) scintigram. At follow-up scintigraphy 6 to 37 weeks following AMI, 57% of patients had a ...
متن کاملRelationships between myocardial perfusion, myocardial necrosis, and technetium--99m pyrophosphate uptake in dogs subjected to sudden coronary occlusion.
The quantitative relationship between abnormalities seen on technetium-99m pyrophosphate (99mTc-PYP) infarct scintigrams and the size of the myocardial infarction is unclear. We evaluated two possible determinants of 99mTc-PYP accumulation: myocardial perfusion measured with 7-10 mu microspheres and the extent of necrosis determined histologically. Hemodynamics and myocardial perfusion to small...
متن کاملAdvantages of technetium pyrophosphate scintigraphy over plasma enzyme analysis in estimation of anterior myocardial infarct size.
Infarct size was estimated by cumulative creatine kinase MB isoenzyme (CKMB-r) release and by technetium 99m stannous pyrophosphate (TcPYP) scintigraphy in 27 patients with acute anterior myocardial infarction. In eight patients, scintigraphy showed a central area of reduced tracer uptake surrounded by a peripheral rim of increased TcPYP accumulation ("doughnut" pattern). This appearance occurr...
متن کاملNon-invasive assessment of the presence and severity of cardiac amyloidosis. A study in familial amyloidosis with polyneuropathy by cross sectional echocardiography and technetium-99m pyrophosphate scintigraphy.
Twelve patients with familial amyloidosis with polyneuropathy were examined both by cross sectional echocardiography and by technetium-99m pyrophosphate scintigraphy to assess involvement of the heart non-invasively. All 12 patients had echocardiographic abnormalities. The most prominent findings were highly refractile myocardial echoes, thickened heart valves, and increased thickness of the he...
