Impaired autonomic control early after CABG may heighten arrhythmic vulnerability; leaves open whether monitoring or intervention improves outcomes.
Does coronary artery bypass surgery impair cardiovascular autonomic control in male patients early postoperatively?
Early after coronary artery bypass surgery, patients exhibit impaired baroreflex sensitivity and vagal suppression with sympathetic predominance, similar to autonomic changes seen in post-myocardial infarction patients.
Robert Bauernschmitt (2004) studied this question.
