OBJECTIVE To evaluate the cost-effectiveness of ivabradine in the treatment of chronic heart failure (CHF) in the context of “Quadruple Therapy” from the perspective of the health system. METHODS Based on real-world cohort data, the Markov model was constructed according to the natural progression of CHF, with a cycle time of 3 months, a study timeframe of 20 years, and a discount rate of 5%. Using quality-adjusted life year (QALY) and incremental cost-effectiveness ratios (ICER) as the output indexes, the cost-utility analysis was used to evaluate the cost-effectiveness of ivabradine in combination with the “Quadruple Therapy” regimen, compared with the “Quadruple Therapy” regimen for the treatment of CHF, and the robustness of the results of the base analysis was verified by univariate sensitivity analysis and probabilistic sensitivity analysis. RESULTS The results of the base analysis showed that the ICER of ivabradine combined with the “Quadruple Therapy” regimen was 165 065.54 yuan/QALY, compared with the “Quadruple Therapy” regimen, which was lower than the willingness-to-pay (WTP) threshold (257 094 yuan/QALY) based on 3 times of China’s gross domestic product (GDP) per capita in 2022. The results of the univariate sensitivity analysis showed that the discount rate had the greatest impact on the robustness of the model. The probabilistic sensitivity analysis showed that the probability that the ivabradine combined with the “Quadruple Therapy” regimen was cost-effective under the WTP threshold in this study was 59.50%. CONCLUSIONS When using 3 times China’s 2022 GDP per capita (257 094 yuan/ QALY) as the WTP threshold, the combination of ivabradine and the “Quadruple Therapy” regimen for treating CHF is cost- effective.

Objective To investigate the infection of Chlamydia pneumoniae and mycoplasma pneumoniae in adults and their association with atherosclerosis,and to provide theoretical guidance for the prevention of such diseases. Methods A case-control study was used to collect 362 patients who were diagnosed with atherosclerosis from January 2019 to December 2021 in Department of Sichuan Bazhong Central Hospital, and 370 cases who were admitted to the hospital during the same period of physical examination without any cardiovascular disease were selected as the control group, and whole blood samples of the two groups of study subjects were collected, and the infection of Chlamydia pneumoniae and mycoplasma pneumoniae was detected by PCR. Results The infection rate of Chlamydia pneumoniae was 35.49%, the infection rate of mycoplasma was 40.37%, and the co-infection rate was 11.37%;The infection rate of Chlamydia pneumoniae in the control group was 12.04%, the infection rate of mycoplasma was 15.83%, and the coinfection rate was 3.14%, and the difference between the two groups was statistically significant ( χ2=10.926, P=0.023). The effects of mycoplasma, chlamydia, and co-infection on atherosclerotic patients have sex differences, mainly manifested as higher infection rates in men; In addition, the effects of mycoplasma, chlamydia, and co-infection on atherosclerosis patients varied by age, mainly in the 55-70 years age group (P<0.05). Multivariate logistic regression results showed that Chlamydia pneumoniae infection was a risk factor for atherosclerosis (OR=1.303, 95%CI: 1.043-1.677) in the whole population, and chlamydia pneumoniae (OR=1.472, 95% CI: 1.037-1.556), mycoplasma (OR=2.003, 95%CI: 1.637-3.842) and co-infection in men (OR=1.937, 95%CI: 1.380-2.184) were risk factors for atherosclerosis, while co-infection in women (OR=1.699, 95%CI: 1.263-1.765) was a risk factor for atherosclerosis. Conclusion Chlamydia pneumoniae and mycoplasma infection are risk factors for atherosclerosis, and their impact on male groups is greater, and more attention needs to be paid to them.

BACKGROUND:Acupotomy is effective in the treatment of knee osteoarthritis,but its mechanism is not very clear. OBJECTIVE:To observe the effect of acupotomy on the apoptosis of knee chondrocytes in knee osteoarthritis rats based on osteoclast associated receptor(OSCAR)-tumor necrosis factor-associated apoptosis-inducing ligand(TRAIL)-osteoprotetin(OPG)pathway. METHODS:Twenty-seven Sprague-Dawley rats were randomly divided into normal group(n=9),model group(n=9)and acupotomy group(n=9).Rats in the normal group were routinely housed without any treatment.Animal models of knee osteoarthritis were established by knee injection of papain.Acupotomy intervention was performed 1 week after modeling,once a week for a total of three times.Relevant tests were performed at the end of the intervention. RESULTS AND CONCLUSION:The Lequesne MG behavioral scores of rats in the model group were elevated compared with the normal group(P<0.01),while the Lequesne MG behavioral scores of rats in the acupotomy group were decreased comparedwith the model group(P<0.01).Hematoxylin-eosin staining results showed that compared with the normal group,the cartilage surface of the rat's knee joints in the model group was worn and uneven and the chondrocytes were swollen,ruptured,reduced in number,and arranged disorderly;while the cartilage surface of the rat's knee joints in the acupotomy group was relatively smooth,and the chondrocytes were high in number and arranged in an orderly manner,with the structure basically clear.Immunohistochemical staining results showed that compared with the normal group,the positive expressions of OSCAR and TRAIL were increased in the model group(P<0.01),while the positive expression of OPG was decreased(P<0.01).Compared with the model group,the positive expressions of OSCAR and TRAIL in the acupotomy group were decreased(P<0.01),while the positive expression of OPG was increased(P<0.01).TUNEL staining results showed that compared with the normal group,the number of apoptotic cells in the model group were increased(P<0.01);compared with the model group,the number of apoptotic cells in the acupotomy group decreased(P<0.01).RT-qRCR and western blot results showed that compared with the normal group,the protein expressions of OSCAR,TRAIL and Bax in the model group were increased(P<0.01),and the protein expressions of OPG and Bcl-2 were decreased(P<0.01);compared with the model group,the protein expressions of OSCAR,TRAIL,and Bax in the acupotomy group were decreased(P<0.01),and the protein expressions of OPG and Bcl-2 were increased(P<0.01).To conclude,acupotomy can reduce cartilage injury of the knee joint in rats with knee osteoarthritis,which may be related to the blockage of mitochondrial pathway apoptotic signaling release by the OSCAR-TRAIL-OPG pathway.

Objectives:To assess the effectiveness and safety of ivabradine for the treatment of chronic heart failure in the context of the new quadruple combination. Methods:Clinical data of 656 chronic heart failure patients hospitalized in Nanjing Drum Tower Hospital from March 2021 to June 2022 were retrospectively collected,and the patients were divided into control group(n=361)and observation group(n=295)according to ivabradine use,and both groups were treated with the new quadruple drug therapy.Propensity score matching was performed,268 patients in the observation group and 268 patients in the control group were successfully matched.The effectiveness(primary endpoint was the composite endpoint of cardiovascular death and rehospitalisation for worsening heart failure within 1 year of discharge;secondary endpoints were rehospitalisation for worsening heart failure,all-cause rehospitalisation,cardiovascular death,and all-cause death)and safety outcome measures(including bradycardia,atrial fibrillation,blurred vision,renal impairment,and hypertension)were compared between the two groups at 1 year after treatment. Results:After matching,there were no statistically significant differences at baseline characteristics between the two groups.Kaplan-Meier survival curve showed that the occurrence rates of primary endpoints(P=0.031),readmission for worsening heart failure(P=0.020),and all-cause readmission(P=0.036)were lower in the observation group than in the control group.Multivariate Cox proportional hazard regression analysis showed that the occurrence rates of primary endpoint events(P=0.045)and readmission for heart failure worsening(P=0.028)were lower in the observation group than in the control group. Conclusions:The ivabradine use on top of the new quadruple therapy regimen in patients with chronic heart failure is beneficial to improve one-year prognosis with favorable safety profile.

OBJECTIVE To evaluate the effects of ivabradine on vascular endothelial function in patients with coronary artery disease. METHODS PubMed, Embase, the Cochrane Library, Web of Science, CNKI, Wanfang Data, VIP and CBM databases were retrieved to collect randomized controlled trials (RCTs) about ivabradine (intervention group) versus placebo or β-blocker (control group) from the inception to Mar. 20th 2023. The meta-analysis was performed by using RevMan 5.4 software after literature screening, data extraction and quality evaluation. RESULTS A total of 12 RCTs were included, involving 1 206 patients. The results of meta-analysis showed that the levels of flow-mediated dilation (FMD) [MD=1.71, 95%CI (0.96, 2.46), P<0.000 01] and nitric oxide (NO) [MD=5.80, 95%CI (5.02, 6.59), P<0.000 01] in the intervention group were significantly higher than control group, while endothelin-1(ET-1) level was significantly lower than control group [MD=-7.45, 95%CI (-8.42, -6.47), P<0.000 01]. There was no statistical significance in nitroglycerin-mediated dilation (NMD) level between 2 groups [MD=0.13, 95%CI(-0.74, 1.00), P=0.77]. Subgroup analyses based on the different medications and intervention time in the control group showed better improvement in FMD level of patients receiving ivabradine, compared with placebo (P<0.05); compared with placebo and β-blocker, the level of NO in patients receiving ivabradine was improved significantly (P<0.05), while ET-1 level was decreased significantly (P<0.05). Regardless of the duration of the intervention, the levels of FMD, NO, and ET-1 in the intervention group were significantly improved compared to the control group (P<0.01), while the difference in NMD was not statistically significant (P>0.05). CONCLUSIONS Ivabradine can improve vascular endothelial function in patients with coronary artery disease.
