Abstract 15018: Is Thirst a Marker or Cause of Complicated Heart Failure Admissions?
Introduction: Thirst is a source of morbidity in heart failure (HF) which may exacerbate congestion and be prognostically important. We hypothesized that patients describing increased thirst would have more advanced heart failure and require longer hospitalizations.
Methods: We performed a prospective study of patients admitted to an advanced HF service requiring intravenous (IV) diuresis. Patients were categorized using a Likert Scale into low (Likert 0-2) or high thirst (Likert 3-4) and compared for baseline indicators of disease severity, presenting jugular venous pressure (JVP), in-hospital diuresis, and length of stay (LOS).
Results: Data were collected for 126 patients; 95 (75%) had low and 31 (25%) had high thirst. Based on thirst status, there were no significant differences in HF severity as assessed by ejection fraction, home diuretic dose, serum creatinine, serum sodium, use of neurohormonal antagonists or admission JVP. Patients with high thirst had longer LOS (median 7 days vs 9 days, p=0.046). However, net recorded weight loss (5.4 kg vs 5.4 kg) and discharge JVP (10cm vs 10 cm) were similar in both groups. There was no significant difference seen in the outcome of readmission-free survival to 30-day post-discharge between the two groups (27% vs 26%).
Conclusions: In patients admitted with HF requiring IV diuresis, increased thirst was a common symptom and associated with an increased LOS despite similar markers of disease severity and renal function, suggesting that patients with high thirst are more difficult to decongest. High thirst may lead to increased fluid intake and retention leading to decompensation and therefore merits more focused study.
