What are cardiovascular actions of epinephrine nonselective (a1,a2,b1,b2)?

Ardiovascular: strengthens the contractility of the myocardium (positive inotropic: β1 action) increases its rate of contraction (positive chronotropic: β1 action), increases cardiac output increased oxygen demands on the myocardium. constricts arterioles in the skin, mucous membranes, and viscera (α1 effects), dilates vessels going to the liver and skeletal muscle (β2effects) Renal blood flow is decreased (vasoconstriction α1 effects) the cumulative effect is an increase in systolic blood pressure, coupled with a slight decrease in diastolic pressure
