Different doses of atorvastatin in the treatment of patients with cardiorenal syndrome Type-2: A retrospective cohort study

Abstract

Objective: To assess the cardiorenal protective effects of different doses of atorvastatin in patients with cardiorenal syndrome (CRS) Type-2. Methods: Medical records of 113 patients with CRS Type-2, admitted to First Affiliated Hospital of Hebei North University from August 2021 to August 2022 and treated with atorvastatin, were retrospectively analyzed. Patients were retrospectively grouped based on the dosage of atorvastatin. A total of 38 patients who received 10mg/day atorvastatin were selected as a Low-dose group, 36 patients who received 20mg/day atorvastatin comprised a Medium-dose group, and 39 patients who received 40mg/day atorvastatin comprised a High-dose group. Cardiac function indicators (Left ventricular end-diastolic dimension [LVEDD], left ventricular end-stage systole diameter [LVESD], and left ventricular ejection fraction [LVEF]), renal function indicators (creatinine [SCr], serum uric acid [SUA], heme oxygenase-1 [HO-1], urinary albumin [UALB]), and inflammatory factors (Serum interleukin-6 [IL-6], hypersensitive C-reactive protein [hs-CRP], and tumor necrosis factor -α [TNF-α]) were compared between the three groups. Results: After the treatment, levels of renal and cardiac function indicators, and inflammatory factor indicators of the three groups were significantly improved compared to the before-treatment levels. The degree of improvement in the Medium-dose and the High-dose groups was significantly higher than in the Low-dose group (p<0.05). There were no significant differences in all cardiorenal function indicators and inflammatory factors between the Medium-dose and the High-dose groups after the treatment. During the treatment process, no adverse events were reported in all three groups. Conclusions: In the treatment of patients with CRS Type-2, medium dose (20mg/day) atorvastatin can have the same therapeutic effect as the high dose (40mg/day) treatment. Medium dose has a good protective effect on the heart and kidneys of the patients, and helps to reduce inflammatory reactions and improve heart and kidney function. doi: https://doi.org/10.12669/pjms.40.4.8706 How to cite this: Zhang E, Xu T, Zhang B, Meng L.
