We herein report two cases of potentially life-threatening arrhythmia due to hyperkalemia triggered by the excessive consumption of "Hoshi-Imo" (dried sweet potato). Both patients with chronic renal disease on renin-angiotensin-aldosterone system inhibitors presented at the emergency room with non-specific symptoms. Electrocardiograms revealed potentially life-threatening arrhythmia due to hyperkalemia in both cases: sinus arrest with a ventricular escape rhythm, tall and peaked T waves; and a widened QRS complex in a nearly sine-wave configuration without discernible P wave. Both patients fully recovered after intensive care for hyperkalemia. Physicians should recognize the excessive consumption of "Hoshi-Imo" may lead to the development of life-threatening arrhythmia, especially in patients with risk factors for hyperkalemia.

Background:The vasopressin type-2 receptor antagonist tolvaptan is an essential tool in the management of decompensated heart failure (HF) in the inpatient setting for short-term use with careful monitoring. There is conflicting evidence, however, for its long-term use.Methods and Results:In this prospective, multi-center, open-labeled, randomized control trial, Assessment of QUAlity of life during long-term treatment of ToLVaptan in refractory HF (AQUA-TLV study), patients with congestive HF refractory to furosemide ≥60 mg/day were randomly assigned to a control group or tolvaptan add-on group and followed for 6 months, after confirmation of baseline urine osmolality ≥350 mOsm/L. Twenty-nine patients (median age, 60 years; 22 male) were enrolled and assigned to a control group (n=16) or a tolvaptan group (n=13). Minnesota Living with Heart Failure Questionnaire score improved significantly in the tolvaptan group (from 58 to 10, P=0.030). In the tolvaptan group, diuretics dose reduced (P=0.001), serum creatinine decreased (P=0.040), and hyponatremia tended to improve (P=0.12). The tolvaptan group had a lower HF readmission rate compared with the control group (0.213 vs. 1.242 events/year, P=0.13).Conclusions:Six-month tolvaptan therapy improved quality of life and renal function and reduced HF readmissions, when given to the estimated responders (UMIN Clinical Trial Registry Number: UMIN 000009604).
