Neither hand blood flow nor sensitivity to cold changed after addition of prazosin, a well known vasodilator, to the original .beta.-blocker. After changing to a .beta.-blocker with a high degree of intrinsic sympathomimetic activity (pindolol), hand blood flow increased and sensitivity to cold decreased in all patients, except 1.Keywords
