Anti-heart antibody immunofluorescence lacks specificity in congestive cardiomyopathy; leaves open whether refined assays could clarify autoimmune subsets.
Does the presence of anti-heart antibodies detected by immunofluorescence indicate a specific abnormality in congestive cardiomyopathy?
Immunofluorescence for anti-heart antibodies is an insensitive test and lacks specificity for congestive cardiomyopathy, likely reflecting general cardiac damage.
Lowry et al. (1983) studied this question.
