Effects of nicorandil on systemic inflammation and oxidative stress induced by percutaneous coronary intervention in patients with coronary heart disease.

ABSTRACT:

Objective

The present study investigated the effects of a bolus intracoronary injection of nicorandil on systemic inflammation and oxidative stress induced by percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD).

Methods

Patients undergoing coronary angiography (CAG) were enrolled into the CAG group (n = 30). Patients undergoing PCI were randomly divided into the PCI (n = 30) and PCI + nicorandil groups (n = 30).

Results

Blood taken from patients in the placebo group 24 hours after PCI exhibited significant increases in the expression of inflammatory indicators and mild increases in the expression of anti-inflammatory indicators. The intracoronary injection of nicorandil reversed the elevation of inflammatory indicators and significantly increased the levels of anti-inflammatory indicators in the blood of patients with PCI. Blood taken from patients in the placebo group 24 hours after PCI also displayed significant decreased superoxide dismutase levels and increased malondialdehyde levels. Nicorandil treatment reversed these changes of oxidative stress marker levels.

Conclusions

These results indicated the possible medical application of intracoronary injections of nicorandil for reducing systemic inflammation and oxidative stress in the peripheral blood of patients undergoing PCI.

The Effects of a Flavonoid-Rich Diet on Oxidative Stress, Inflammation, and Lipid Profile after Elective Percutaneous Coronary Intervention: A Randomized Clinical Trial.

Project description:Antioxidant-rich foods may decrease oxidative stress and have a direct impact on atherosclerosis by reducing low-density lipoprotein (LDL) oxidation. Our aim was to assess the impact of a flavonoid-rich diet on oxidative stress, inflammatory response, and lipid profile in patients with coronary artery disease submitted to elective percutaneous coronary intervention (PCI). Thirty-three patients submitted to elective PCI were randomly allocated to follow either a flavonoid rich antioxidant (AOX) diet or a control diet based on National Cholesterol Education Program Adult Treatment Panel III recommendations. Patients were followed for 6 months. Dietary intake was recorded at the start and at the end of the follow-up period, as were oxidative stress markers (ferric reducing ability of plasma and protein sulphydryl) and C-reactive protein (CRP). Patients randomized to follow the AOX diet had a reduction in energy, carbohydrate, and lipid intake, as well as increased flavonoid intake. Compared to the control group, there were no changes in oxidative stress markers or CRP in the patients following the AOX diet, but these patients had a significant decrease in LDL cholesterol levels. In conclusion, the findings of this study suggest that a flavonoid-based antioxidant-rich diet is not associated with reductions in oxidative stress or inflammatory markers 6 months after percutaneous coronary intervention. Nonetheless, patients in the intervention group experienced significant reductions in LDL cholesterol, which may indicate cardiovascular benefits of AOX diets despite of inflammation and oxidative stress markers.

Impact of intracoronary nicorandil before stent deployment in patients with acute coronary syndrome undergoing percutaneous coronary intervention.

Project description:The present study aimed to clarify the effect of bolus intracoronary nicorandil on inflammatory, oxidative and adherent indicators in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). This randomized controlled trial (RCT) was performed to detect the inflammation and oxidative stress in intracoronary blood both before and after PCI. In total, 65 consecutive patients undergoing PCI were classified into a nicorandil therapy group (n=32) or a placebo group (n=33). All procedures were performed at Shandong University Qilu Hospital, China, during the period from March, 2016 to May, 2017. Intracoronary blood from patients who received nicorandil therapy during PCI showed no change in soluble CD40 ligand (sCD40L) concentration (1.86±0.08 vs. 1.90±0.09 ng/ml, P=0.12) but a significant increase was noted in the control group (1.87±0.17 vs. 2.82±0.26 ng/ml, P<0.01). This indicated a relative reduction in sCD40L level after PCI in the nicorandil group. We further demonstrated an increase in superoxide dismutase (SOD) activity (29.37±0.81 vs. 31.03±0.60 U/ml, P<0.001) and a reduction in lipid peroxidation (3.84±0.99 vs. 4.23±0.13 U/ml, P=0.001) in the nicorandil group but observed no change in the placebo group. ICAM-1 levels showed no change in the nicorandil group (69.54±6.89 vs. 72.01±8.25 ng/ml, P=0.83) but a significant increase in the control group after PCI in intracoronary blood (56.57±4.96 vs. 76.81±6.88 ng/ml, P=0.002). No changes were found in hs-CRP, TNF? and sVCAM-1 levels in coronary blood for both groups before and after PCI in ACS patients. Our findings demonstrate that intracoronary bolus nicorandil therapy has a significant effect on the inhibition of inflammatory indicators and oxidative stress in patients with ACS during PCI. This suggests a possible medical application of nicorandil for reducing inflammation and oxidative stress.

The effects of percutaneous transluminal coronary intervention on biomarkers of oxidative stress in the erythrocytes of elderly male patients.

Project description:OBJECTIVES:Oxidative stress plays a key role in the pathogenesis of coronary artery disease. The aim of this study was to compare the effects of percutaneous transluminal coronary angioplasty (PTCA) and elective coronary angiography (EC) on erythrocytic antioxidant defense in elderly male patients. METHODS:Twenty-three stable angina pectoris (SAP) patients undergoing PTCA and 18 patients with ischemic symptoms scheduled to undergo diagnostic EC were included in the study. The concentrations of malondialdehyde (MDA) and reduced glutathione (GSH) and the activities of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and cytosolic glutathione peroxidase (GSH-Px) were examined in the erythrocytes before, immediately after and 2 weeks following PTCA or EC. RESULTS:The MDA concentrations were significantly higher and SOD-1, CAT, and GSH-Px activities were significantly lower in the PTCA group than in the EC group at baseline. Two weeks after treatment, the activities of the enzymes significantly increased in both groups, whereas the MDA concentrations decreased only in the PTCA patients. CONCLUSIONS:The results confirm that an advanced state of atherosclerosis is related to greater levels of oxidative stress. The study indicates that both procedures may induce antioxidant defenses; however, PTCA exclusively induces a long-term reduction in lipid peroxidation.

Effect of nicorandil administration on myocardial microcirculation during primary percutaneous coronary intervention in patients with acute myocardial infarction.

Project description:Introduction:Prevention of the no-reflow phenomenon has a crucial role in primary percutaneous coronary intervention (P-PCI) procedures. Aim:To assess the effects of early intracoronary administration of nicorandil (NIC) during P-PCI on myocardial microcirculation in patients with acute myocardial infarction (AMI). Material and methods:A total of 120 patients with first acute anterior wall ST segment elevation myocardial infarction who underwent P-PCI were randomly divided into two groups: the NIC group (A, n = 60) and the placebo group (B, n = 60). Before stent placement, NIC or normal saline was injected using a guiding catheter. The thrombolysis in myocardial infarction (TIMI) grade, TIMI myocardial perfusion grade (TMPG), resolution of ST segment elevation (defined as > 50% decrease in ST elevation) 1 h after surgery, and 99Tcm-methoxyisobutyl isocyanide (MIBI) rest myocardial perfusion imaging (MPI) via single-photon emission computed tomography (99Tcm-MIBI SPECT) findings 10 days after surgery were compared between the two groups. Results:The number of patients who achieved TIMI grade 3 (96.67% vs. 86.67%; p = 0.047) and TMPG 3 (95% vs. 83.33%; p = 0.040) was higher in the NIC group than in the placebo group. Resolution of ST segment elevation occurred in 95% and 81.67% of the patients in the NIC and placebo groups, respectively (p = 0.023); the MPI score of the two groups was 4.1 ±1.89 and 7.3 ±2.65, respectively (p = 0.014). Conclusions:Early coronary administration of NIC can significantly reduce the damage in the myocardial microcirculation caused by P-PCI and the myocardial infarct size in patients with AMI.

Nicorandil in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention: a systematic review and meta-analysis.

Project description:BackgroundNicorandil, as an adjunctive therapy with primary percutaneous coronary intervention (PCI), had controversial benefits in cardioprotection in patients with acute myocardial infarction (AMI).Methods and resultsWe performed a systematic review of randomized controlled trials (RCTs) comparing treatment with nicorandil prior to reperfusion therapy with control (placebo or no nicorandil) in patients who suffered from AMI and performed primary PCI. PubMed, EMBASE and CENTRAL databases and other sources were searched without language and publication restriction. 14 trials involving 1680 patients were included into this meta-analysis. Nicorandil significantly reduced the incidence of thrombolysis in myocardial infarction (TIMI) flow grade ? 2 (risk ratio [RR], 0.57; 95% confidence interval [CI]: 0.42 to 0.79), the Timi frame count (TFC) (mean difference [MD], -5.19; 95% CI: -7.13 to -3.26), increased left ventricular ejection fraction (LVEF) (%) (MD, 3.08; 95% CI: 0.79 to 5.36), and reduced the incidence of ventricular arrhythmia (RR, 0.53; 95% CI: 0.37 to 0.76) and congestive heart failure (CHF) (RR, 0.41; 95% CI: 0.22 to 0.75). No difference in the pear creatine kinase (CK) value (MD, -290.19; 95% CI: -793.75 to 213.36) or cardiac death (RR, 0.39; 95% CI: 0.09 to 1.67) was observed.ConclusionsNicorandil prior to reperfusion is associated with improvement of coronary reflow as well as suppression of ventricular arrhythmia, and further improves left ventricular function in patients who suffered from AMI and underwent primary PCI. But the definite clinical benefits of nicorandil were not found, which may be due to the small sample size of the selected studies.

Coronary artery bypass graft versus percutaneous coronary intervention in acute heart failure.

Project description:ObjectiveMyocardial ischaemia is a leading cause of acute heart failure (AHF). However, optimal revascularisation strategies in AHF are unclear. We aimed to compare two revascularisation strategies, coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI), in patients with AHF.MethodsAmong 5625 consecutive patients enrolled prospectively in the Korean Acute Heart Failure registry from March 2011 to February 2014, 717 patients who received CABG or PCI during the index hospitalisation for AHF were included in this analysis. We compared adverse outcomes (death, rehospitalisation for HF aggravation or cardiovascular causes, ischaemic stroke and a composite outcome of death and rehospitalisation for HF aggravation or cardiovascular causes) with the use of propensity score matching.ResultsFor the propensity score-matched cohort with 190 patients, CABG had a lower risk of all-cause mortality than PCI (83 vs 147 deaths per 1000 patient-years; HR 0.57, 95% CI 0.34 to 0.96, p=0.033) during the median follow-up of 4 years. There was also a trend towards lower rates of rehospitalisation due to cardiovascular events or HF aggravation. Subgroup analysis revealed that the adverse outcomes were significantly lower in the CABG group than in PCI group, especially in patients with old age, three-vessel diseases, significant proximal left anterior descending artery disease and those without left main vessel disease or chronic total occlusion.ConclusionsCompared with PCI, CABG is associated with significant lower all-cause mortality in patients with AHF. Further studies should evaluate proper revascularisation strategies in AHF.Clinical trial registrationNCT01389843; Results.

Family care and subjective well-being of coronary heart disease patients after percutaneous coronary intervention: Mediating effects of coping strategies.

Project description:ObjectivesTo analyze the correlations between family care, coping strategies and the subject well-being (SWB) of patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).MethodsFrom November 2019 to October 2020, 264 CHD patients who had undergone PCI were enrolled in this questionnaire survey. The research tools applied included General Information Questionnaire, the Adaptation, Partnership, Growth, Affection and Resolve, Medical Coping Modes Questionnaire, and the General Well-being Schedule. SPSS 24.0 and Amos 23.0 software packages were used for statistical analysis.ResultsThe mean scores for family care, confrontation, avoidance, acceptance-resignation and SWB, were 7.59 ± 2.24, 20.03 ± 3.78, 16.49 ± 2.70, 10.42 ± 2.01, and 73.31 ± 11.63, respectively. Subgroup analysis showed that the path coefficient between family care and subjective well-being was higher in males than females. Family care was directly related to coping strategies. The coping strategies were directly related to SWB, while family care showed an indirect association with SWB via coping strategies.ConclusionsFamily care can improve CHD patients' SWB post-PCI, and coping strategies are important for the link between family care and SWB. Also, men received more family care than women. Based on a patient's characteristics, healthcare providers can promote patients' positive coping strategies, increase their perceived family care, and improve the patient's SWB.

Effects of a psychological intervention programme on mental stress, coping style and immune function in percutaneous coronary intervention patients.

Project description:PurposeThis study aimed to assess the effects of a psychological intervention programme on the mental stress, coping style and cortisol and IL-2 levels of patients undergoing percutaneous coronary intervention (PCI).MethodsA total of sixty cardiovascular patients scheduled for PCI with clear anxiety and depression screened by the Hospital Anxiety and Depression Scale were randomly divided into an experimental (n = 30) and control (n = 30) group. The participants in the experimental group received cognitive therapy, relaxation therapy and emotional support. Self-reported questionnaires, including the Self-Report Symptom Checklist (SCL-90) and the Medical Coping Mode Questionnaire (MCMQ), and levels of IL-2 and cortisol were collected at baseline and the day before discharge.ResultsCompared with the controls, patients in the intervention group had a better mental state and coping style (confrontation), higher levels of IL-2 and lower levels of cortisol (all P<0.05).ConclusionsThe psychological intervention programme effectively improved mental state, reduced negative coping styles, increased levels of IL-2, and decreased cortisol levels in patients undergoing PCI. This programme may be an effective preoperative nursing intervention for PCI patients.Trial registrationChinese Clinical Trail Registry ChiCTR-IOR-16007864.

Effect of nicorandil treatment adjunctive to percutaneous coronary intervention in patients with acute myocardial infarction: a systematic review and meta-analysis.

Project description:Objective: There is controversy whether nicorandil treatment has cardioprotective effects in patients with acute myocardial infarction (AMI) following percutaneous coronary intervention (PCI). This meta-analysis was conducted to assess the efficacy of nicorandil on functional and clinical outcomes after PCI.Methods: Systematic databases were searched to retrieve studies that compared the effect of nicorandil with a control group in patients with AMI who underwent PCI. Outcomes related to coronary blood flow, and functional and clinical outcomes were extracted and a meta-analysis was performed. Trial sequential analysis was conducted to estimate the required sample size for statistical power.Results: Twenty-four trials involving 2965 patients with AMI were enrolled. Pooled results showed that nicorandil treatment significantly suppressed the incidence of no-reflow phenomenon and reperfusion arrhythmia after reperfusion, improved the left ventricular ejection fraction and left ventricular end-systolic volume index, and reduced major adverse cardiovascular events and cardiovascular death. Trial sequential analysis confirmed the effect of nicorandil in reducing the incidence of no-reflow phenomenon and follow-up major adverse cardiovascular events in patients with AMI after PCI.Conclusion: Our findings suggest that nicorandil treatment adjunctive to reperfusion therapy improves myocardial reperfusion, cardiac function, and clinical outcomes in patients with AMI.

Managing Heart Failure Patients with Multivessel Disease - Coronary Artery Bypass Graft versus Percutaneous Coronary Intervention.

Project description:The foundation of treatment for heart failure with reduced ejection fraction is guideline-directed medical treatment. However, surgical revascularisation offers improved survival and quality of life for patients with more extensive coronary disease and the greatest degree of left ventricular systolic dysfunction and remodelling. The most commonly considered surgical interventions for patients with heart failure with reduced ejection fraction are coronary artery bypass surgery, sometimes combined with surgical ventricular reconstruction and surgery for mitral regurgitation. In this review, the author considers the risks and benefits of coronary artery bypass graft versus percutaneous coronary intervention in the management of heart failure patients with multivessel disease.
