Effect of Anemia on the Prognosis of Patients with Ventricular Tachyarrhythmias
Section snippets
Methods
The present study retrospectively included all consecutive patients with ventricular tachyarrhythmias from 2002 until 2016, as recently published.10, 11, 12
For the present analysis, risk stratification was performed according to anemia. Anemic patients (hemoglobin levels <12.0 g/dl) were compared with non–anemic patients (hemoglobin levels ≥12.0 g/dl). To allow for a better comparison than previous studies, anemia was defined as hemoglobin (Hb) levels <12.0 g/dl, independent of gender.8 Overall
Results
A total of 2,184 consecutive patients presenting with ventricular tachyarrhythmias on admission were included in the present study. Of these, 30% were anemic, and 70% were non–anemic. As outlined in Table 1, ventricular tachycardia (VT) and ventricular fibrillation (VF) were distributed equally (VT: 55% vs 58%; VF: 45% vs 42%). In general, anemic patients showed higher rates of CPR (59% vs 41%, p = 0.001), mainly attributed to in-hospital CPR (38% vs 13%, p = 0.001), whereas non–anemic patients
Discussion
The present study evaluated the frequency and types of anemia, as well as their prognostic impact on patients presenting with ventricular tachyarrhythmias on admission. Anemia was found in 30% of these patients. The most common type of anemia was hemorrhagic (29%), followed by hypoproliferative (27%), and mild forms of anemia (20%). Of anemic patients presenting with ventricular arrhythmias, 10% suffered cardiac death at 24 hours after admission. Hemolytic and undefined anemia after completed
