Serum levels of @entity6949 in XXXX with uncomplicated @entity302 .

@entity1 @entity410 @entity296 @entity16 @entity6949 @entity3999 @entity302
BACKGROUND: @entity6949 ( @entity6949 ) is a myofibrillar protein regulating the interaction of actin and @entity3999 . It is 100% tissue specific for the heart and is an excellent serum marker for detecting @entity296 . Based on previous studies, contradictory results have been reported about elevation of serum levels of @entity6949 in @entity1 presenting with subacute or acute @entity16 with or without @entity410 . Here we assess serum levels of @entity6949 in @entity1 following uncomplicated @entity302 and with a healthy cardiovascular system. METHODS: In this analytical cross-sectional study, 49 @entity1 (age range: 12-65 years) with uncomplicated @entity302 and no history of cardiac problems were included. @entity6949 level was evaluated in @entity1 between 6 h and 10 days after a @entity410 . Electrocardiography and echocardiography were also performed. Variables including number of @entity410 , age at first @entity410 , and time elapsed from the last @entity410 , in addition to demographic variables, were also evaluated. RESULTS: Average age of @entity1 was 21.18 years (standard deviation [SD] +/-8.37) with a male/female ratio of 2.26. Mean elapsed time from the last @entity410 was 54 h (SD +/-52.97). @entity6949 level was within the normal range (<0.1 ng/mL) in all @entity1 with a mean level of 0.026 ng/mL (SD +/-0.015). A significant statistical correlation was found between serum level of @entity6949 and number of @entity302 (Spearman r = 0.743, p <0.001). CONCLUSIONS: Serum level of @entity6949 following @entity410 was within normal limits in 12 to 65-year-old @entity1 with uncomplicated @entity302 and healthy cardiovascular system. However, this level was higher in @entity1 with more than three repeated @entity410 . Repeated measurement of level of @entity6949 up to several days after presence of a @entity410 may be helpful in further assessment of this relationship.
