Technetium-99m Stannous pyrophosphate (cas 15578-26-4) (99mTc-PYP) myocardial scintigrams were obtained in 35 acute pericarditis and in three chronic constrictive pericarditis patients. Thirteen of 35 acute pericarditis patients (37%) and one of three chronic constrictive pericarditis patients (33%) had abnormal scintigrams (a diffuse pattern in eight patients and a regional pattern in six patients). Of the 17 acute pericarditis patients with classic ST-segment changes of acute pericarditis, 10 (56%) had abnormal scintigrams compared to three of 17 patients (18%) without these ECG change (P < 0.02). These data indicate that pericardial disease may cause an abnormal scintigram. Therefore, one must rule out pericardial disease before concluding that a positive scintigram is due to acute myocardial infarction.
