The scintigraphic diagnosis of inflammatory heart disease

Comparative ability assessment of ^99mTc-pyrophosphate and ^99mTc-HMPAO-leucocytes scintigraphies in diagnostics of myocarditis and infectious endocarditis is carried out. We have included 49 patients in our study with suspected myocarditis (14 patients), with postmyocarditis cardiosclerosis (13 patients), with suspected infectious endocarditis (16 patients). The control group was presented by 11 patients with extra-cardiac inflammatory diseases. SPECT with ^99mTc-HMPAO-leucocytes has visualized pathological fixation of radiopharmaceutical at 14 patients with myocarditis, at 13 patients with infectious endocarditis, and at 2 patients with postmyocarditis cardiosclerosis. In control group, we have only revealed extracardiac inflammatory focuses. The use of ^99mTc-pyrophosphate allows visualizing accumulation of this indicator in both all patients with myocarditis an postmyocarditis cardiosclerosis, and at one patient of control group.
