Patients suffering from heart failure had a lower BMI (21.9 ± 3.3 vs. 27.1 ± 4.4 kg/m2, p = 0.016) and a lower geriatric nutritional risk index (93.1 ± 13.3 vs. 117.6 ± 6.4, p < 0.01), a nutritional status indicator that was measured based on serum albumin and body weight, and a lower incidence of dyslipidemia (36.4% vs. 85.7%, p = 0.04), in contrast with patients without heart failure. The gene discussed is ALB; the disease is heart failure.
