Background: Oral administration of tolvaptan, a vasopressin V2 receptor antagonist, significantly reduces deterioration of renal function, which has recently been highlighted as an exacerbating factor for adverse events in patients with acute heart failure. In the present study we tested the hypothesis that concomitant administration of tolvaptan with a conventional diuretic is beneficial for perioperative body fluid management in patients who have undergone cardiac surgery. Methods and Results:In all, 280 patients who underwent cardiac surgery were prospectively randomized to concomitant treatment with tolvaptan and a conventional diuretic (tolvaptan group; 147 patients) or treatment with a conventional diuretic alone (control group; 133 patients). Groups were compared in terms of the time required to restore preoperative body weight and the incidence of worsening renal function (WRF), defined as an increase in the serum creatinine level ≥0.3 mg/dL. The time required to restore preoperative body weight was significantly shorter in the tolvaptan than control group (mean [±SD] 3.97±1.95 vs. 5.02±2.83 days, respectively; P<0.001). The incidence of WRF was significantly lower in the tolvaptan than control group (n=11 [7.5%] vs. n=25 [18.8%], respectively; P=0.011). Conclusions:Administration of tolvaptan with conventional diuretics in the early postoperative period after cardiac surgery could be beneficial in maintaining urine output without affecting renal function and may thus help avoid WRF.

Urate reduced NO production by impaired phosphorylation of eNOS in HUVEC via activation of UATs, which could be normalized by urate lowering agents.

Carvedilol suppressed apoptosis of HL-1 cells expressing E334K MyBPC through modification of pro- and anti-apoptotic proteins, whose was associated with an increase of Cav 1.2 protein expression.

Background: We examined the outcome of debranching thoracic endovascular aortic repair (d-TEVAR) without sternotomy for distal aortic arch aneurysm in patients aged ≥75 years. Methods: Patients who underwent d-TEVAR or TAR for aortic arch aneurysm between 2008 and 2015 at our hospital and aged ≥75 years were included. Age, sex, left ventricular ejection fraction, preoperative creatinine level, diabetes, cerebrovascular disease, and chronic obstructive pulmonary disease were matched using PS. Results: Among 74 patients (d-TEVAR: 51, TAR: 23), 17 patients in each group were matched. No difference in surgical outcome was detected between the d-TEVAR and TAR groups, including 30-day death (0% vs. 0%), hospital death (5.8% vs. 0%: p = 0.31) and incidence of cerebral infarction (5.8% vs. 7.6%: p = 0.27) as well as the long-term outcomes of 5-year survival (92.8% vs. 74.8%: p = 0.30) and 5-year aorta-related event-free rate (88.2% vs. 100%: p = 0.15). Average duration of ICU stay (1.3 ± 1.1 days vs. 5.6 ± 1.3 days: p = 0.025) and hospital stay (16.5 ± 5.2 days vs. 37.7 ± 19.6 days: p = 0.017) were significantly shorter in the d-TEVAR group. Conclusion: Our results indicated that d-TEVAR is less invasive without affecting long-term outcome up to 5 years. Although the number of the patients included in the study was small, debranching TEVAR could be one of the treatments of the choice in the elderly, especially with comorbidities.
