Effectiveness of Atorvastatin in the Treatment of Asymptomatic Heart Failure After Myocardial Infarction: A Clinical Study

Silent heart failure after myocardial infarction has not been effectively treated. Atorvastatin has certain efficacy in the treatment of heart failure. Our clinical study aimed to investigate the effectiveness of atorvastatin in patients with asymptomatic heart failure after myocardial infarction. A total of 162 patients with asymptomatic heart failure after myocardial infarction in our hospital from August 2018 to August 2019 were randomly divided into the observation group (81 cases were treated with atorvastatin on the basis of routine therapy) and the control group (81 cases were treated with routine symptomatic treatment). The clinical curative effect, the level of related inflammatory cytokines, cardiac function index, and vascular endothelial function were compared between the two groups. Before intervention, there was no significant difference in tumor necrosis factor (TNFα), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), plasma N-terminal B-type natriuretic peptide (NT-ProBNP), left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), left ventricular posterior wall thickness (LVPWT), asymmetric dimethyarginine (ADMA), activity of nitric oxide synthase (NOS), nitric oxide (NO) and flow-mediated dilation (FMD) between the two groups. After intervention, TNFα, hs-CRP, IL-6, NT-ProBNP, LVEF, LVEDD, LVESD, LVPWT, ADMA, NOS, NO, and FMD were improved in both groups. The clinical curative effect, TNFα, hs-CRP, IL-6, NT-ProBNP, LVEF, LVEDD, LVESD, LVPWT, ADMA, NOS, NO, and FMD in the observation group showed significantly greater results than those in the control group (P < 0.05). Atorvastatin exerted a great effect in treating asymptomatic heart failure after myocardial infarction, which can evidently reduce the level of related inflammatory cytokines, improve cardiac function, and regulate vascular endothelial function. Hence, atorvastatin is considered a valid and alternative approach in clinical practice.
