Fu D, et al. - In this study including consecutive patients who underwent resection surgery for non-small cell lung cancer (NSCLC), researchers determined if heart rate could be a risk factor for cardiopulmonary complications (CPCs) after lung cancer resection. Within postoperative 30 days, comparisons for demographic, clinical characteristics and laboratory parameters were performed among patients with or without CPCs. To determine the predictive role of preoperative resting heart rate for CPCs, they used receiver operating characteristic (ROC) curve analysis. Findings demonstrated an increased risk of postoperative CPCs in relation to elevated preoperative resting heart rate in this study population.
