Previous work demonstrated that Na(+)-K(+) pump activity within skeletal muscle is attenuated in myocardial infarction (MI). This may lead to enhanced interstitial K(+) concentration ([K(+)](o)) in the muscle. We tested the hypothesis that [K(+)](o) rises with muscle contraction and that, in rats with MI, the rate of rise in [K(+)](o) is greater than it is in control animals. Microdialysis probes were inserted in the skeletal muscle of six healthy control and six MI rats. The ends of the probes… CONTINUE READING
