Abstract:
Objective: To study therapeutic effect of atorvastatin on patients with asymptomatic heart failure (AHF) after myocardial infarction, and its influence on prognosis.Methods: Clinical data of 100 AHF patients after myocardial infarction, who were treated in our hospital from Jul 2014 to Jul 2015, were analyzed.According to random number table, patients were randomly and equally divided into routine treatment group and atorvastatin group (received atorvastatin based on routine treatment).Cardiac function indexes, plasma levels of BNP and N-terminal pro B-type natriuretic peptide (NT-proBNP), 6min walking distance (6MWD) and cardiac function score were measured and compared between two groups before and after treatment.Course of treatment was one year.Results: Compared with before treatment, after treatment, there were significant rise in left ventricular ejection fraction (LVEF) and 6MWD, and significant reductions in left ventricular end-diastolic dimension (LVEDd), left ventricular end-systolic dimension (LVESd), plasma levels of BNP and NT-proBNP, and cardiac function score in both groups(P=0.001 all).Compared with routine treatment group after treatment, there were significant rise in LVEF [(52.48±8.65)% vs.(57.86±9.70)%] and 6MWD [(262.60±12.40)m vs.(282.65±15.50)m], and significant reductions in LVESd [(36.23±2.13)mm vs.(30.08±2.05)mm], LVEDd [(58.61±6.40)mm vs.(51.25±6.18)mm], plasma levels of BNP [(267.48±42.10)pg/ml vs.(149.40±32.30)pg/ml] and NT-proBNP [(524.65±138.60)pg/ml vs.(406.20±112.45)pg/ml], and cardiac function score [(2.30±0.22) scores vs.(1.15±0.10) scores] in atorvastatin group(P<0.01 all).Conclusion: Atorvastatin can alleviate left ventricular remodeling, reduce plasma levels of BNP and NT-proBNP, and improve cardiac function in AHF patients after myocardial infarction, which is worth extending.
