In a multicenter study, a total of 380 patients with myocardial infarction, myocarditis and cardiomyopathy underwent 111In-Antimyosin Fab myocardial imaging. 111In-Antimyosin Fab was administered intravenously and myocardial images were obtained 48 hours later. Only 3 patients developed mild adverse effects. Human antimouse antibodies were detected in 7 patients. Positive scans in patients with myocardial infarction were seen in 92/119 (77%) within 2 weeks after the onset of myocardial infarction, in 58/71 (82%) at 3-4 weeks, in 20/22 (91%) at 4-8 weeks and 17/31 (55%) thereafter. The location of myocardial damage delineated by 111In-Antimyosin Fab imaging was concordant with the infarct location by ECG and coronary angiography. In patients with myocarditis, 111In-Antimyosin Fab uptake was positive in 7/12 (58%) within 8 weeks and 6/17 (35%) thereafter. Positive 111In-Antimyosin Fab scans were seen in 12/36 (33%) in dilated cardiomyopathy and in 17/19 (89%) in hypertrophic cardiomyopathy. Although the mechanism of persistently positive 111In-Antimyosin Fab images in the subacute to chronic stage of myocardial infarction and myocarditis remains to be clarified, 111In-Antimyosin Fab may be useful for the detection of the diseases and in evaluating the prognosis of patients with cardiomyopathy.

UI	MeSH Term	Description	Entries
D007140	Immunoglobulin Fab Fragments	Univalent antigen-binding fragments composed of one entire IMMUNOGLOBULIN LIGHT CHAIN and the amino terminal end of one of the IMMUNOGLOBULIN HEAVY CHAINS from the hinge region, linked to each other by disulfide bonds. Fab contains the IMMUNOGLOBULIN VARIABLE REGIONS, which are part of the antigen-binding site, and the first IMMUNOGLOBULIN CONSTANT REGIONS. This fragment can be obtained by digestion of immunoglobulins with the proteolytic enzyme PAPAIN.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009202	Cardiomyopathies	A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).

D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
