This study provides evidence that in selected patients who have undergone cardiac surgery, rehabilitation outcomes are also favorable in patients aged 75 yrs or more, and an early rehabilitation program is as effective and safe as a traditionally late one.

Background-Previous studies have shown that oxidative protein damage is independently associated with low grip strength and that dietary intake and circulating levels of anti-oxidant vitamins are positive predictors of muscle strength among older persons. Since uric acid (UA), has strong anti-oxidant properties, we tested the hypothesis that UA levels is cross-sectionally associated with muscle strength and protective against the decline of strength over the aging process.
