BACKGROUND: Cardiorenal syndrome (CRS) remains the leading cause of death in hospitalized patients for all disease entities. Sacubitril/Valsartan (Sac/Val) therapy has been proved to improve prognostic outcome in patients with heart failure or chronic kidney disease. This study tested the hypothesis that combined levosimendan and Sac/Val was superior to just one therapy on protecting the heart and kidney against simultaneous heart and kidney ischemia (I) (for 50-min)-reperfusion (R) (for 7-days) (i.e., double IR) injury (defined as CRS).
METHODS AND RESULTS: Adult-male Spraque-Dawley rats (n = 40) were equally categorized into group 1 (sham-operated control), group 2 (double IR), group 3 [double IR+levosimendan (10 mg/kg by intra-peritoneum administration at 30 min/followed by days 1-5 once daily after IR procedure)], group 4 [double IR+Sac/Val (10 mg/kg, orally at 30 min/followed by days 1-5 twice daily after IR procedure)], and group 5 (double IR+Sac/Val+levosimendan). By day 7 after double-IR, the left-ventricular-ejection fraction (LVEF)/left-ventricular-fraction-shortening (LVFS) were highest in group 1, lowest in group 2 and significantly higher in group 5 than in groups 3/4, but they showed no difference between groups 3/4, whereas the circulatory heart-failure (brain-natriuretic peptide)/proinflammatory (suppression of tumorigenicity-2) biomarkers, blood-urea-nitrogen/creatinine and ratio of urine protein to creatinine (all p < 0.0001) exhibited an opposite pattern of LVEF among the groups. The protein expressions of inflammatory (tumor necrosis factor-α/interleukin-1ß/matrix metalloproteinase-9)/oxidative-stress (NOX-1/NOX-2/NOX-4)/apoptotic (mitochondrial-Bax/caspase-3/poly-(ADP-ribose)-polymerase)/fibrotic (Smad3/transforming growth factor-ß)/mitochondrial-damaged (cytosolic-cytochrome-C)/myocardial-hypertrophic (ß-MHC) biomarkers in LV myocardium exhibited an opposite pattern of LVEF among the groups (all p < 0.0001). The cellular expressions of inflammatory (CD68)/DNA-damaged (γ-H2AX) biomarkers and infarct/fibrotic areas in LV myocardium and kidney displayed an opposite pattern of LVEF among the groups (all p < 0.0001).
CONCLUSION: Combined levosimendan and Sac/Val was superior to merely one therapy on protecting the heart and kidney as well as preserving their functions against double IR injury.
