Although glucagon exerts positive inotropic effects in patients with no or mild impairment of cardiac function, similar effects are not consistently observed in patients with chronic heart failure. Accordingly, the inotropic effects of glucagon on papillary muscles from normal cats and cats in which right ventricular failure had been produced for 4-145 days(More)
Because of conflicting reports on the influence of extracellular potassium concentration ([K]o) on the inotropic action of cardiac glycosides, we compared the effects of varying [K]o (1.5, 4.5, and 7.5mM) on the inotropic action and myocardial concentration of tritiated digoxin (5 X 10~M) using the isolated cat papillary muscle. The time course of the(More)
To clarify the suppressant action of diphenylhydantoin (DPH) on digitalis-induced arrhythmias we studied effects of DPH and digoxin, alone and in combination, on contractile force, sodium-potassium adenosinetriphosphatase (Na + -K ATPase) activity, and potassium (K) balance in dog hearts perfused with Krebs-Ringer's solution. Neither control perfusion nor(More)
In order to study the cardiac catheterization experience in hospitals without cardiovascular surgery programs, data was collected from all 8 Washington "satellite" laboratories over a 5-year period. There were 5 deaths (0.13%) during the 3878 coronary arteriography procedures. Of the 5, 4 had severe left main coronary artery lesions. Of these patients, 2(More)
