Correlation among serum prealbumin level, red cell distribution width and severity of heart failure in advanced aged male patients / 心血管康复医学杂志

ABSTRACT

Objective: To explore the correlation among serum prealbumin (PAB) level, red cell distribution width (RDW) and cardiac function in advanced aged male patients with chronic heart failure (CHF). Methods: Research objects included 60 patients with heart failure（28 cases with NYHA class Ⅱ and 32 cases with NYHA class Ⅲ-Ⅳ, heart failure group）and 30 cases with normal cardiac function admitted in the same period（normal control group）. Serum PAB, hemoglobin (Hb) concentration and RDW, red blood cell (RBC) count were measured. Patients all received echocardiography examination. Changes of all indexes were compared among patients with different cardiac function class. Results: ① Compared with normal control group, there was significant decrease in serum PAB level [(252±49) mg/L vs. (185±36) mg/L] and significant increase in RDW [(13.84±0.60) % vs. (15.79±1.33) %] in heart failure group, and compared with class Ⅱ group, there was significant decrease in serum level of PAB and significant increase in RDW in class Ⅲ-Ⅳ group, P<0.01 all; ② Compared with normal control group, there were significant decrease in E/A [(1.02±0.36) vs. (0.75±0.18)] and left ventricular ejection fraction [LVEF, (59±9) % vs. (49±11) %] in heart failure group, and the worse cardiac function was, the lower these two indexes were, P<0.01 all; ③ Pearson linear correlation regression analysis indicated that PAB was positively correlated with E/A and LVEF (r=0.451, P<0.05; r=0.596, P<0.05), and RDW was negatively correlated with E/A and LVEF (r=-0.391, P<0.05; r=-0.574, P<0.05) in heart failure group. Conclusion: Prealbumin and red cell distribution width are closely correlated to cardiac function class in advanced aged male patients. Both of them can indirectly reflect cardiac function in advanced aged patients with chronic heart failure.
