Effect of theophylline on adaptation of the heart to myocardial ischemia during percutaneous transluminal coronary angioplasty in patients with stable angina pectoris

Am J Cardiol. 1997 Feb 15;79(4):475-7. doi: 10.1016/s0002-9149(96)00787-4.

Abstract

This study was designed to examine whether theophylline, an adenosine receptor antagonist, affects cardiac adaptation to ischemia during progression of repetitive balloon inflations of percutaneous transluminal coronary angioplasty (PTCA). Theophylline abolished this cardiac adaptation, suggesting that endogenous adenosine is a key mediator for cardiac adaptation during PTCA.
