Data presented as median (interquartile range) for continuous variables and number (percentage) for categorical variables. Operative mortality is based on the society of thoracic surgeons definition and includes all deaths, regardless of cause, occurring during the hospitalization in which the operation was performed, even if after 30 days (including patients transferred to other acute care facilities); and all deaths, regardless of cause, occurring after discharge from the hospital, but before the thirtieth postoperative day. Abbreviations: TIA, transient ischemic attack; MI, myocardial infarction.
