Abstract/OtherAbstract:
BACKGROUND: Statins are one of the most common agents prescribed for ischemic stroke patients, but their side effects on the liver are worrisome to both physicians and patients. This study aimed to analyze the features and related factors of the hepatic side effects of statins in patients with ischemic stroke.
METHODS: Four hundred and eighty-one patients with ischemic stroke who had been treated with statins at our department from July 1, 2008 to June 30, 2009 were investigated retrospectively. Liver function, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST), within 6 months after they began to use statins and related factors were analyzed.
RESULTS: The incidence of mild ALT and AST elevation, less than three times the upper limit of normal, and the incidence of moderate elevation, ALT and AST levels 3 - 10 times the upper limit of normal, in ischemic stroke patients who had been treated with statins were 2.3% and 2.1%, respectively. These incidences were higher than in patients with common hyperlipidemia or coronary heart disease. The relatively high incidence was associated with older age (≥ 65 years) and chronic liver diseases, and was not related to the type of stroke, gender, and reduction of low-density lipoprotein. The levels of ALT and AST normalized after withdrawal of statins or lowering the dosage. None of the patients developed hepatic failure.
CONCLUSIONS: Asymptomatic elevation of ALT and AST after administration of statins is more likely to occur in ischemic stroke patients than in others, and the elevation is related to age and chronic liver diseases. However, statins are still safe for ischemic stroke patients.
