Effect of fluvastatin combined with β-receptor-blockers on cardiac function and peripheral blood NF-κB and sST2 in patients with coronary heart disease complicated with heart failure

Objective: To investigate the effects of fluvastatin combined with β-receptor-blockers on cardiac function and peripheral blood NF-κB and sST2 in patients with coronary heart disease (CHD) complicated with heart failure. Methods: A total of 90 CHD patients complicated with heart failure from September 2016 to September 2017 were selected and randomly divided into the control group and the observation group, with 45 cases in each group. The control group was treated with arotinolol and the observation group was treated with arotinolol combined with fluvastatin. The clinical efficacy of the two groups after treatment was compared. The cardiac function index, blood lipid index, inflammatory factor and serum NF-κB and sST2 levels were detected and compared between the two groups. Results: The effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the cardiac function indexes of the two groups were significantly improved (P<0.05). The LVEF and LVFS of the observation group were significantly higher than those of the control group, and LVEDD and LVESD of the observation group were significantly lower those of the control group (P<0.05). The serum lipid index and inflammatory factors of the two groups were significantly decreased after treatment. The hs-CRP, TNF-α, TC and LDL-C of the observation group were significantly lower than those of the control group after treatment (P<0.05). After treatment, the serum NF-κB and sST2 were significantly decreased in both groups, and the serum NF-κB and sST2 in the observation group were significantly lower than those in the control group. There was no significant difference in the incidence of adverse reactions between the two groups (P<0.05). Conclusions: Fluvastatin combined with β-receptor-blockers can reduce the level of blood lipid and inflammatory factors more effectively and improve the clinical efficacy of the CHD patients complicated with heart failure. It can effectively reduce serum NF-κB and sST2 more effectively and improve prognosis.

The Efficacy and Safety of Drug-Coated Balloons in the Treatment of Acute Myocardial Infarction

The incidence of acute myocardial infarction (AMI) is increasing year by year, which seriously endangers human health around the world. The preferred treatment strategy for AMI patients is the use of drug-eluting stents (DES), as there is ample evidence to suggest that stent implantation can reduce major adverse cardiovascular events (MACEs). With the application of drug-coated balloons (DCBs) and the enhancement of the concept of interventional without implantation, the question is whether DCBs can be safely and effectively used in patients with AMI? The purpose of this study was to investigate the safety and effectiveness of DCBs in the treatment of AMI. A retrospective review of clinical data was conducted on 55 AMI patients who underwent primary percutaneous coronary intervention (PCI) from January 2020 to December 2021. Of these patients, 25 were treated with DCBs and 30 were treated with DESs. Optical coherence tomography (OCT) was used to measure the minimum lumen diameter, lumen stenosis, and coronary artery dissection before and after surgery, and angina pectoris attacks and various MACEs were recorded at 1, 6, and 12 months after surgery. The results showed that there were no significant differences in clinical baseline data between the two groups. However, the minimum lumen diameter of the DCB group immediately after the operation was smaller than that of the DES group, and the stenosis degree of the lumen in the DCB group was higher than that in the DES group. The incidence of coronary artery dissection in the DCB group was significantly higher than that in the DES group, but the majority of them were type B. At 1, 6, and 12 months after treatment, there was no significant difference in the occurrence of MACEs between the two groups. In conclusion, DCBs is a safe and effective treatment for AMI. However, the incidence of coronary artery dissection in DCB patients is higher than that in DES patients, but the majority of them are type B. .

The impact analysis of the oxidative stress injury and inflammatory factor level for ticagrelor assisted PCI in the treatment the elderly patients with ST segment elevation acute myocardial infarction

Objective:To investigate the effect of ticagrelor assisted PCI in treatment the elderly patients with acute ST elevation myocardial infarction (STEMI) on oxidative stress and inflammatory factor level.Methods:A total of 100 cases elderly patients with STEMI were selected that they were being treated with PCI. According to the digital list method was divided into the study group and control group, and 50 cases in each group. The control group was treated with PCI and the strong heart, anticoagulation, vasodilation, prevention of infection and other comprehensive treatment of myocardial infarction, the study group were given ticagrelor treatment which was based on the comprehensive treatment of myocardial infarction. The level change were compared that oxidative stress index (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) activity and inflammatory factor hypersensitive C reactive protein (hs-CRP), N-terminal pro brain natriuretic peptide (NT-proBNP) and interleukin -6 (IL-6) between the two groups in before treatment (T0), treatment with 7 d (T1), 14 d (T2), 30 d (T3).Results:(1)There was no significant difference in serum MDA, GSH-Px and SOD levels between the two groups in the T0. Two groups serum MDA level were higher than theT0, and the GSH-Px and SOD levels were lower than the T0 after operation in the T1.And the serum MDA level were lower than T0, T1, GSH-Px and SOD levels were higher than T0, T1in the T2, T3.The T3 serum MDA level was lower than T2, GSH-Px and SOD levels were higher than T2.Even the serum MDA was significantly lower than the control group T1, T2, T3 and the GSH-Px and SOD were higher than those of the control group T1, T2, T3 at the study groupT1, T2, T3, the difference was statistically significant. (2)There was no significant difference in T0 of the serum hs-CRP, IL-6 and NT-proBNP levels between the two groups. Two groups serum hs-CRP, IL-6 and NT-proBNP level were higher than the T0 after operation in the T1.And the serum hs-CRP, IL-6 and NT-proBNP levels were higher than T0, T1in the T2, T3.The T3 serum hs-CRP, IL-6 and NT-proBNP levels were lower than T2.and that the serum hs-CRP, IL-6 and NT-proBNP levels were significantly lower than the control group T1, T2, T3 at the study groupT1, T2, T3, so the difference was statistically significant.Conclusion:The treatment method will be able to reduce oxidative stress injury and effectively control the inflammatory response that ticagrelor assisted PCI in treatment the elderly patients with acute ST elevation myocardial infarction (STEMI).

Transluminal stent graft placements for the treatment of Standford B type aortic dissection

Management of patients with aortic dissection includes medical and surgical treatments.Because of the high surgical morbidity and mortality rate, transluminal stent graft placement （TSGP） has emerged as a new treatment instead of open surgery for aortic dissection of a descending aortic intimal tear.1 In our institute, we use TSGP to seal the entry site for both acute onset and chronic Standford B type aortic dissections. The implantation technique and outcome of this treatment are discussed.

Naoxintong capsules(脑心通胶囊)modulates tumor necrosis factor-α-induced endothelial senescence through silent information regulator 1 signaling

OBJECTIVE:To investigate the protective effects of Naoxintong capsules(脑心通胶囊,NXT)on tumor necrosis factor-α(TNF-α)-induced senescence inendothelial cells and its mechanism.METHODS:Human umbilical vascular endothelial cells(HUVECs)were treated with TNF-α±NXT and assessed for silent information regulator 1(SIRT1)expression and signaling.Cells were stained with beta-galactosidase to assess the levels of cellular senescence.SIRT1 was silenced through siRNA transfection.RESULTS:TNF-αtreatment led to the downregulation of SIRT1,resulting in forkhead box O1(FoxO-1)acetylation,p53 acetylation and enhanced p21 expression.Following TNF-αtreatment,higher SAβ-Gal activity improved.TNF-αenhanced the migration of HUVECs and increased SIRT1 expression,both of which were attenuated by NXT treatment.The downstream targets of SIRT1 including FoxO-1/p53/p21 were also modulated,and HUVECs were protected from TNF-α-induced senescence.In contrast,the NXT-mediated protection was prevented by SIRT1 silencing.CONCLUSIONS:These findings suggest that sustained endothelial senescence can be induced by TNF-αstimulation via the SIRT1/FoxO-1/p53/p21 pathway.The protection of NXT against TNF-αwas partially mediated through its effects on SIRT1.This highlights the promise of NXT as a therapeutic for atherosclerosis.
