Comparative Study Clinical Trial
Serum levels of smooth muscle heavy-chain myosin in patients with ectopic pregnancy.
Previous studies have suggested that serum markers of smooth muscle destruction have utility in predicting ectopic pregnancy. Our goal was to determine whether a novel marker of muscle destruction, smooth muscle heavy-chain myosin (SMHC), is elevated in the serum of patients with ectopic pregnancy. ⋯ There is a statistically significant elevation of serum SMHC levels in tubal pregnancy, although our data suggest that the assay has limited clinical utility as a lone marker for ectopic pregnancy. Further investigation is needed to determine whether the assay has a role as an adjunct in the evaluation of suspected ectopic pregnancy.
