Background/Aims: Preoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) is a useful predictor of postoperative cardiovascular complications. The present study investigated whether blood NT-proBNP values are suitable for predicting postoperative cardiovascular complications after non-cardiac surgery in elderly patients showing normal left ventricular (LV) function on preoperative echocardiograms. Methods: This study was performed by analyzing the medical records of elderly patients referred to the cardiology department for the purpose of assessing their cardiac function before orthopedic surgery. Of the patients who underwent echocardiography and NTproBNP assessment simultaneously, 275 patients aged ≥ 70 years and with an LV ejection fraction of ≥ 55% were included in the study. Results: Major adverse cardiac and cerebrovascular events (MACCEs) occurred in 33 (12%) of the 275 patients, and the NT-proBNP concentration was higher in patients with complications than in those without complications (1,904.20 ± 2,300.23 vs. 530.58 ± 882.27 pg/mL, p 80 years (odds ratio, 2.313; p = 0.047) and an increased blood NT-proBNP concentration (odds ratio, 3.189; p = 0.009) were independent risk factors for the prediction of MACCEs. Conclusions: Although elderly patients scheduled to undergo non-cardiac surgery may show normal LV systolic function on echocardiography, measurement of their preoperative blood NT-proBNP concentration is useful for predicting MACCEs occurring after non-cardiac surgery.

Therapy-related myeloid neoplasms have been well characterized. However, precursor B-cell acute lymphoblastic leukemia in patients with prior malignancies is uncommon, and the effect of prior cytotoxic therapy on development of precursor B-cell acute lymphoblastic leukemia is controversial. Therapy-related precursor B-cell acute lymphoblastic leukemia has been reported occasionally. However, cytotoxic therapy-related precursor B-cell acute lymphoblastic leukemia has been reported in Korea only rarely. We herein describe two cases of therapy-related precursor B-cell acute lymphoblastic leukemia. (Korean J Med 2013;85:96-100)
