Validation of a modified scoring system for cardiovascular risk associated with major lung resection

Abstract

The incidences of severe postoperative cardiovascular complications were similar in the published derivation group and the current validation group. The ThRCRI score successfully stratified risk for postoperative cardiovascular events after major lung resection in the validation group. The expected risk in the validation group was similar to the observed risk, indicating that ThRCRI accurately predicted specific risk rather than just relative risk. Further evaluation of the utility of this scoring system is warranted.
