Fe and Zn concentrations in the heart of 13 FA^a patients and 8 normal controls (bulk digests).

aAbbreviations: FA, Friedreich ataxia; Fe, iron; LVW, left ventricular wall; RVW, right ventricular wall; VS, ventricular septum; Zn, zinc bResults of Fe and Zn are expressed as mean μg metal/g wet tissue ± standard deviation. Number of FA patients and normal controls are given in parentheses. In one FA patient, only LVW tissue was available. cp-values are based on statistical comparison by two-tailed t-test at α = 0.05, assuming unequal variances Fe and Zn concentrations in the heart of 13 FAa patients and 8 normal controls (bulk digests).
