Background: The timing of ventricular assist device (VAD) implantation is always a matter of debate, especially when a patient is referred from a non-VAD institute. We focused on objective noninvasive parameters at the time of admission to a VAD implant center and analyzed the factors predicting the necessity of early VAD.
Methods and Results: We retrospectively analyzed advanced heart failure (HF) patients referred since January 2011, including patients less than 65 years old. They all had a history of hospitalization for HF management in non-VAD institutes within 1 month before referral. We excluded patients transferred with mechanical circulatory support. We enrolled 46 patients (40 males, 39.8±13.4 years old). Among them, 26 patients had a VAD implanted or died within 120 days. By multivariable logistic analysis using admission parameters, systolic blood pressure (BP) <93 mmHg [odds ratio (OR) 13.335], hemoglobin <12.7 g/dl (OR 12.175) and serum total cholesterol <144 mg/dl (OR 8.096) were significant predictors of early VAD requirement. We constructed a scoring system according to the ORs, and the area under the receiver-operating characteristic curve was 0.913.
Conclusions: Low BP, low serum cholesterol and anemia on admission predict early VAD in advanced HF patients who have been treated in non-VAD institutes. Such patients should be promptly referred to a VAD implant center.
