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.
ABSTRACT
Objective: This research was conducted to discuss the recent prognosis of patients with acute cerebral infarction (ACI) combined with cerebral-cardiac syndrome (CCS). Method: Eighty-seven patients with ACI were selected, which were divided into the ACI group (52 patients) and the CCS group (35 patients) according to whether the CCS was combined, and another 30 health controls were selected as the control group. Serum hypoxia-inducible factor (HIF)-1α and vascular endothelial growth factor (VEGF) levels of subjects in each group at the 1st day, the 3rd day, and the 7th day after admission were measured by enzyme-linked immunosorbent assay. After discharge for 30 days, the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS) score were utilized to evaluate the prognosis of patients. The role of serum HIF-1α and VEGF levels in the prognosis of ACI combined with CCS patients was assessed by receiver operating characteristic curve and the binary logistic regression analysis. Results: Higher serum HIF-1α and VEGF levels were observed in the CCS and ACI groups versus the control group, and the levels of which were even higher in the CCS group in comparison to the ACI group. According to the prognosis of the NIHSS score, fasting blood glucose (FBG), Acute Physiology and Chronic Health Evaluation II score, creatine kinase-MB (CK-MB), and HIF-1α and VEGF levels at the 7th day of admission were higher while Glasgow coma scale (GCS) score was lower in the poor prognosis group than those in the good prognosis group, and the area under the curve (AUC) of serum HIF-1α and VEGF levels was 0.895 (95% confident interval [CI], 0.786-1.000), and 0.855 (95% CI, 0.731-0.980). According to the prognosis of the mRS score, FBG, CK-MB, and HIF-1α and VEGF levels at the 7th day of admission were higher while GCS score was lower in the poor prognosis group than those in the good prognosis group, and the AUC of serum HIF-1α and VEGF levels was 0.850 (95% CI, 0.722-0.979) and 0.901 (95% CI, 0.798-1.000). The results of the binary logistic regression analysis revealed that HIF-1α and VEGF levels may be independent risk factors influencing the prognosis of ACI combined with CCS. Conclusion: Serum HIF-1α and VEGF have a good predictive value for assessing the recent prognosis of patients with ACI combined with CCS, which could be independent risk factors influencing the prognosis of disease.
ABSTRACT
OBJECTIVE: To evaluate the correlation of galectin-3 (Gal-3) and lipoprotein-associated phospholipase A2 (Lp-PLA2) with the severity of coronary artery disease and major adverse cardiovascular events (MACE). METHODS: 130 patients diagnosed with coronary heart disease (CHD) by coronary angiography from October 2018 to August 2019 in the Department of Cardiology, the First Affiliated Hospital of Hebei North University, were matched into the CHD group, with 68 cases in the mild stenosis (MS) group (degree of stenosis 50%~75%), and 62 cases in the severe stenosis (SS) group (degree of stenosis ≥75%). For comparison, patients with negative results of angiography during the same period (stenosis degree <50%) were assigned to the normal group. Indicators for detection included plasma Gal-3, Lp-PLA2 concentrations, Gensini scores, and MACE events in a 30-day follow-up visit. RESULTS: Remarkably higher plasma Gal-3 and Lp-PLA2 concentrations in the CHD group were observed in comparison with the normal group. The SS group obtained a more positive result regarding plasma Gal-3 and Lp-PLA2 concentrations and Gensini scores than the MS group (P<0.05). The highest concentration of plasma Gal-3 and Lp-PLA2 was detected in the multi-vessel disease (MVD) group, followed by the double-vessel disease (DVD) group, and finally the single-vessel disease (SVD) group. Pearson correlation analysis revealed a positive correlation of plasma Gal-3 and Lp-PLA2 concentrations with Gensini scores (P<0.05). Results of the follow-up visit presented strong relevance between noticeably higher concentrations of the plasma Gal-3 and Lp-PLA2 and MACE events (P<0.05). Increased Gal-3 and Lp-PLA2 are risk factors for the prognosis of coronary artery disease. CONCLUSION: Plasma Gal-3 and Lp-PLA2 concentrations in patients with CHD are strongly related to the severity of coronary artery disease and MACE events, which is valuable for assessing the risk of patients in clinical practice.
ABSTRACT
This study was aimed to examine the possible underlying cardioprotective efficacy of tangeretin (TAN) in rats exposed to isoproterenol (ISP). Forty male SD rats were separated into four equal groups as the control group, ISP (myocardial infarction; MI group) group rats which were injected intraperitoneally (ip) with 85 mg/kg of ISP. Treatment TAN groups (TAN 50 and TAN 100) rats were orally pretreated with TAN (50 or 100 mg/kg) for 28 days before ISP exposure. Pretreatment with TAN (50/100) significantly reduced (p < .05/0.01) the infarct size, levels of inflammatory markers, cardiac marker enzymes, apoptotic markers along with improved antioxidants. Histo-morphological results also well-supported the results of the above biochemical parameters by displaying normal myofibrillar arrangement in TAN pretreated rats. Moreover, the protein expressions of pPI3K and pAkt were considerably elevated in rats administered with TAN. Collectively, TAN pretreatment (especially TAN 100) display better cardioprotective activity against ISP-induced MI rats. PRACTICAL APPLICATIONS: Tangeretin (TAN) has been reported to exhibit an array of biological functions including cardioprotective, hepatoprotective, and renoprotective activities. However, the in-depth mechanism is still lacking, which results in this study. Our results indicate that TAN could effectively reduce cardiac infarct size, inflammatory markers, oxidative stress, apoptotic markers, by modulating (upregulating) the protein expressions of the PI3K/Akt signaling pathway. Thus, demonstrating that TAN could be a strong contender for developing a cardioprotective agent and can recommend along with conventional cardioprotective drugs for abolishing MI-related complications/symptoms. Nevertheless, further human studies are needed to confirm the above suggestion.
