Abstract Background Cardioprotective effect of remote ischemic preconditioning (RIPC) in cardiovascular surgery is controversy. This study investigated whether RIPC combined with remote ischemic postconditioning (RIPostC) reduces myocardial injury on donor hearts in patients undergoing heart transplantation. Methods One hundred and twenty patients scheduled for orthotopic heart transplantation were enrolled and randomly assigned to an RIPC+RIPostC group (n=60) or a control (n=60) group. In the RIPC+RIPostC group, four cycles of 5-min ischemia and 5-min reperfusion were applied on the right upper limb by a cuff inflated to 200mmHg after anesthesia induction (RIPC) and 20 minutes after aortic declamping (RIPostC). Serum cardiac troponin I (cTnI) level was determined preoperatively and at 3, 6, 12, 24 h after aortic declamping. Postoperative clinical outcomes were recorded. The primary endpoint was comparison of the cTnI levels at 6 h after aortic declamping. Results Compare with the preoperative baseline, serum cTnI levels peaked at 6h after aortic declamping in two groups. Compare with the control group, RIPC+RIPostC significantly reduced the serum cTnI levels at 6h after aortic declamping (38.87±31.81 vs 69.30±34.13ng/ml, P=0.018). There was no significant difference in in-hospital morbidity and mortality between the two groups. Conclusion In patients undergoing orthotopic heart transplantation, RIPC combined with RIPostC reduced myocardial injury at 6h after aortic declamping,while we found no evidence of this function provided by RIPC+RIPostC could improve clinical outcomes

Background: Peri-interventional myocardial injury occurs frequently during transcatheter aortic valve implantation (TAVI). We assessed the effect of remote ischemic preconditioning (RIPC) on myocardial injury, acute kidney injury (AKIN) and 6-month mortality in patients undergoing TAVI. Methods: We performed a prospective single-center controlled trial. Sixty-six patients treated with RIPC prior to TAVI were enrolled in the study and were matched to a control group by propensity-score. RIPC was applied to the upper extremity using a conventional tourniquet. Myocardial injury was assessed using high-sensitive troponin-T (hsTnT), and kidney injury was assessed using serum creatinine levels. Data were compared with the Wilcoxon-Rank and McNemar tests. Mortality was analysed with the log-rank test. Results: TAVI led to a significant rise of hsTnT across all patients (p < 0.001). No significant inter-group difference in maximum troponin release or areas-under-the-curve was detected. Medtronic CoreValve and Edwards Sapien valves showed similar peri-interventional troponin kinetics and patients receiving neither valve did benefit from RIPC. AKIN occurred in one RIPC patient and four non-RIPC patients (p = 0.250). No significant difference in 6-month mortality was observed. No adverse events related to RIPC were recorded. Conclusion: Our data do not show a beneficial role of RIPC in TAVI patients for cardio- or renoprotection, or improved survival.

Introduction: Contrast-induced acute kidney injury (CIN-AKI) is a serious complication of coronary angiography. Given the weaknesses in the common protective methods used to prevent CIN-AKI, a safe and effective strategy is needed. RIPC has been shown to have a nephroprotective effect. Objectives: We aimed to determine the protective effect of RIPC on CIN-AKI after angiography or percutaneous coronary intervention (PCI) in low-risk patients. Patients and Methods: In our study, 140 low-risk patients who needed angiography or PCI, were assigned to either RIPC or control group. In each group, serum creatinine and urinary neutrophil gelatinaseassociated lipocalin (uNGAL) were measured before the procedure. Serum creatinine was measured daily for 2 days and uNGAL was measured 6 and 24 hours after the procedure. Diagnosis of AKI was, according to the Kidney Disease; Improving Global Outcomes (KDIGO) criteria (2012). Results: The mean age in the remote ischemic preconditioning (RIPC) group was 56.8 ± 11.4 years and 56.3 ± 11.8 years in the control group. We observed no significant difference regarding patient’s characteristic and renal biomarkers at baseline. There was no significant difference in the incidence of AKI (P = 0.116). The uNGAL increased by 36.2% 6-hour after the procedure in patients with AKI, while at the same time, this biomarker increased only by 4.3% in patients without AKI. Conclusion: We concluded that RIPC, with 3 cycles of 5-minute ischemia and 5-minute reperfusion, did not decrease CIN-AKI or altering renal biomarkers course in low-risk patients undergoing coronary angiography or PCI. Additionally, uNGAL, seems to be an appropriate biomarker for early diagnosis of CIN-AKI, 6 hours after contrast media exposure.
