High In-hospital glycemic variability (GV) is an Independent Predictor of 1-yr Mortality in Acute HF Patients suggests a recent study published in the Cardiovascular Diabetology.
High glycemic variability (GV) is a poor prognostic marker in cardiovascular diseases. We aimed to investigate the association of GV with all-cause mortality in patients with acute heart failure (HF).
The Korean Acute Heart Failure registry enrolled patients hospitalized for acute HF from 2011 to 2014. Blood glucose levels were measured at the time of admission, during hospitalization, and at discharge. They included those who had 3 or more blood glucose measurements in this study. Patients were divided into two groups based on the coefficient of variation (CoV) as an indicator of GV. Among survivors of the index hospitalization, we investigated all-cause mortality at 1 year after discharge. Results
• The study analyzed 2,617 patients (median age, 72 years; median left-ventricular ejection fraction, 36%; 53% male).
• During the median follow-up period of 11 months, 583 patients died. Kaplan–Meier curve analysis revealed that high GV (CoV > 21%) was associated with lower cumulative survival
• Multivariate Cox proportional analysis showed that high GV was associated with an increased risk of 1-year mortality. • High GV significantly increased the risk of 1-year mortality in non-diabetic patients but not in diabetic patients
• High in-hospital GV before discharge was associated with all-cause mortality within 1 year, especially in non-diabetic patients with acute HF.
