Eleven of the 21 patients had significantly raised serum concentrations (shown in bold) of P III P, 7S collagen, or TnT, even though their CK values were within the normal range.
CK, creatine kinase; LDEDP, left ventricular end diastolic pressure; CI, cardiac index; LDEDVI, left ventricular end diastolic volume index; EF, left ventricular ejection fraction.
