Interarm systolic blood pressure difference is associated with XXXX after noncardiac surgery.

@entity1 @entity296
BACKGROUND: @entity296 after non-cardiac surgery (MINS) is closely related to increased cardiovascular mortality. AIM: Our aim was to evaluate the relationship between MINS and interarm systolic blood pressure difference (IASBPD) - which has previously been shown to correlate with the frequency of cardiovascular events and arterial arteriosclerotic processes. METHODS: This observational, single-center cohort study included 240 consecutive noncardiac surgery @entity1 aged >= 45 years. Simultaneous blood pressure recordings were taken preoperatively and IASBPD was calculated. @entity1 electrocardiography recordings and high sensitivity cardiac troponin T (hscTnT) levels were obtained for a period of 3 days postoperatively. RESULTS: Postoperatively, 27 @entity1 (11.3%) were found to have MINS when hscTnT >= 14 ng/L was taken as a cut-off value. IASBPD >10 mmHg was found in 44 @entity1 (18.3%). When IASBPD was accepted to be a continuous variable, there was a higher IASBPD value in the MINS group (9.4  5.0 vs. 4.5  3.8, p<0.000). When @entity1 were grouped as those having IASBPD>10 mmHg and those not, exaggerate IASBPD was found to be more frequent in @entity1 developing MINS (16 (59.3%) vs. 28 (13.1%) respectively, p<0.000). Multiple logistic regression analysis found IASBPD>10 mmHg to be independently associated with the development of MINS (OR: 30.82 (CI: 9.14-103.98), p<0.000). ROC curve analysis showed that the optimal IASBPD cut-off value for predicting MINS was 11.5 mmHg, with a sensitivity of 61.0% and specificity of 89.1% (AUC = 0.79; 95% CI: 0.71-0.87). CONCLUSIONS: Increased IASBPD is closely related to development of MINS. The preoperative measurement of blood pressure from both arms may be an important and easy to use clinical tool in determining cardiovascular risk.
