RT Journal A1 DALESSANDRI KM T1 EFfect of β-adrenergic blockade on the growth rate of abdominal aortic aneurysms JF Archives of Surgery JO Archives of Surgery YR 1989 FD March 1 VO 124 IS 3 SP 388 OP 389 DO 10.1001/archsurg.1989.01410030138025 UL http://dx.doi.org/10.1001/archsurg.1989.01410030138025 AB To the Editor.—I read the recent article in the Archives by Leach et al1 with great interest. The effect of propranolol hydrochloride on other types of aneurysmal disease could also be explored. For example, the incidence of coronary artery aneurysms in a coronary artery surgery study of 20087 patients was 5%.2 The cause was primarily atherosclerotic or congenital, with over half secondary to atherosclerosis. The main complications reported were rupture with sudden death, thrombosis, and myocardial infarction secondary to embolization. Medical treatment generally consists of the use of antithrombotic drugs. Often a patient has associated coronary artery stenosis and poststenotic dilation and aneurysm formation. Often these patients are receiving propranolol for treatment of associated disease, such as hypertension, angina pectoris, and the control of certain types of cardiac arrhythmias. Therefore, in a large medical center such as Yale (New Haven, Conn), where many coronary angiographic studies are
