To the Editor:
I read with interest the letter by Ms Rochelle Wynne. Dr Chanda and I appreciate her nice review and comments. It is possible that an individual with adequate pulmonary function prior to coronary artery bypass grafting can experience severe respiratory failure postoperatively secondary to other organ dysfunction or failure. These types of analysis in a large data set certainly have major benefits for improved patient care and health care providers. Our study [1] is consistent with identification of intraoperative and postoperative risk factors in addition to preoperative ones predicting respiratory failure after coronary artery bypass grafting. Our study makes no suggestion that coronary artery bypass grafting should be withheld from any particular patient, but rather that these conditions should be addressed prior to operation, when possible. The results further emphasize the practice of preoperative optimization of acute and chronic extracardiac problems prior to coronary bypass operations to minimize the risk of postoperative respiratory failure. More studies are warranted to better identify the value of postoperative patient factors and care processes after coronary artery bypass grafting.
