Autonomic Vulnerability, Intraoperative Hypotension Burden, and Myocardial Injury After Noncardiac Surgery in Older Adults: A Propensity Score-Matched Retrospective Cohort Study.
BACKGROUND Myocardial injury after noncardiac surgery (MINS) is common and often clinically silent. Older adults with diabetes mellitus (DM) and/or hypertension (HTN) may have autonomic dysfunction that impairs hemodynamic compensation during surgical stress. We hypothesized that a preoperatively identifiable autonomic...
