Background:Depressed hemodynamics stimulates arginine vasopressin (AVP) release, but the relationship between plasma AVP levels (P-AVP) and cardiac parameters, especially in patients with stage D heart failure (HF) receiving guideline-directed medical therapy, has not examined.Methods and Results:Data including P-AVP were obtained from 162 in-hospital patients with stage D HF and from 80 patients receiving ventricular assist device (VAD, n=46) or heart transplantation (HTx, n=34) at 3 months after surgery. In the HF group, considerably high P-AVP (5.9±6.1 pg/ml) negatively correlated with serum sodium concentration (S-Na, 135.3±5.8 mEq/L, r=–0.548 [P<0.01]) and cardiac index (CI, 2.2±0.5 L·min–1·m–2, r=–0.458 [P<0.01]). After VAD/HTx treatment, improvement in the CI (2.7±0.5 L·min–1·m–2[P<0.01] vs. HF) was accompanied by normalization of serum sodium concentration (S-Na; 138.2±2.0 mEq/L [P<0.01] vs. HF) and suppressed release of AVP (1.7±3.4 pg/ml [P<0.01] vs. HF). P-AVP positively correlated with only S-Na (r=0.454 [P<0.01]), whereas no correlation was observed with CI after VAD/HTx treatment. P-AVP ≥5.3 pg/ml well predicted poor 2-year survival in HF group (60% [P<0.01] vs. 90%).Conclusions:Low cardiac output stimulates AVP release via a non-osmotic process that results in hyponatremia and poor prognosis in patients with stage D HF. After sufficient recovery of cardiac output by cardiac replacement therapy, AVP release is suppressed and is mainly regulated by serum osmolality. (Circ J 2014; 78: 2259–2267)

Background: The continuous flow (CF) left ventricular assist device (LVAD) has replaced the pulsatile flow (PF) LVAD because of its advantages of better patient survival and higher quality of life. However, “late-onset right ventricular failure (RVF)” after CF LVAD implantation has emerged as an increasing concern, but little is known about the mechanism. Methods and Results: We retrospectively analyzed the 3-month hemodynamic and echocardiographic data from 38 consecutive patients who had received CF LVADs, and from 22 patients who had received PF LVADs. Late-onset RVF was defined as persistent right ventricular stroke work index (RVSWI) <4.0g/m2 at any rotation speed and after saline infusion test at 5 weeks after implantation of CF LVAD. Patients with late-onset RVF had significantly impaired exercise tolerance indicated by shorter 6-min walking distance and lower peak VO2, and worsened tricuspid regurgitation, together with enlargement of the RV under CF LVAD treatment (all P<0.05). Univariable analyses demonstrated that preoperative smaller LV diastolic diameter (LVDd) was the risk factor for late-onset RVF with a cutoff value of 64mm calculated by ROC analysis (area under curve, 0.925). In contrast, there was no correlation between preoperative LVDd and postoperative RVSWI in the PF LVAD group, though their preoperative background was worse than that of the CF group. Conclusions: In the setting of preoperative small LVDd, CF LVAD may cause late-onset RVF by leftward shift of the interventricular septum.  (Circ J 2014; 78: 625–633)
