Effects of halothane and isoflurane on calcium and potassium channel currents in canine coronary arterial cells.

abstract：BACKGROUND:Age is a known risk factor for postoperative complications, but the genetic factors that account for variability in age at presentation for surgery have not been characterized. Because thrombosis is a critical process in the development of coronary syndromes, the authors hypothesized that patients bearing th...
