Table 1. Patient demographics.

Neither pathology reports nor slides were available for 3 patients; therefore, they were excluded from classification of fibrosis. Inotropes include dopamine, dobutamine, vasopressin, epinephrine, norepinephrine, and milrinone. NA = not available. EF = Ejection Fraction, ACEI = Angiotensin Converting Enzyme Inhibitor.
