Twenty-year follow-up of patients with new perioperative Q waves after coronary artery bypass grafting

Am J Cardiol. 2000 Sep 15;86(6):677-9, A8. doi: 10.1016/s0002-9149(00)01052-3.


It is unclear whether the development of new Q waves on the electrocardiogram after coronary artery bypass grafting (CABG) is associated with an adverse prognosis. We analyzed the 20-year survival of 227 patients who underwent CABG, and found that new perioperative Q waves had no impact on long-term survival; therefore, conservative management may be appropriate for uncomplicated patients with new Q waves after CABG.
