Background: Coronary artery disease today is a major contributor to mortality and morbidity from cardiovascular disease. The drug, interventional and surgical methods are used to treat coronary artery stenosis. Statins are the most commonly used drugs for stenosis and coronary artery disease. Low-density lipoprotein (LDL) The purpose of this study was to evaluate the effect of atorvastatin on LDL and C-reactive protein (CRP) reduction in patients.
Methods: This study was a systematic review and meta-analysis. Articles were selected using the keywords of atorvastatin, LDL, C-reactive protein (CRP) and reduction, and searches in Scopus, Google Scholar and PubMed databases from March 2003 to February 2018. For this purpose, all analytical, clinical trials, cross-sectional, and case-control studies were searched and collected in association with the efficacy of atorvastatin on low density lipoprotein and CRP.
Results: In the initial search, 90 papers were found and evaluated. Finally, 20 papers were analyzed. The studies were published. The total sample size was 21609 persons with an average sample size of 1080 in each study. Twenty studies were entered into the final analysis. The LDL-lowering rate was 51 mg/dl with atorvastatin (I2=98.48, P<0.001). Also, CRP reduction before and after administration of atorvastatin was   1.99 (0.96-3.03) and 0.76 (0.08-1.43), respectively. The results of meta-regression of age-related studies showed that LDL levels were low in studies with lower age, and LDL levels were low in studies with higher age. The results of a meta-regression study of atorvastatin in terms of body mass and the association of low-density lipoprotein with atorvastatin showed that in those with a higher body mass, low-density lipoprotein decreased.
Conclusion: According to the results, the use of atorvastatin reduces the amount of C-reactive protein (CRP). The rate of low density lipoprotein (LDL) reduction was better and faster in young and obese people. It is recommended that people have a proper diet and regular exercise in their daily schedule.
