The aim of our work was to investigate the role of K_ATP channels in the cardioprotection induced by pyridoxal-5-phosphate (PLP) in aging. <b>Methods:</b> Experiments were performed on adult and old (aged 24 months) male Wistar rats, which were divided into 3 groups: adults, old, and old PLP-treated rats. PLP was administered orally once a day for 14 days at a dose of 0.7 mg/kg. The levels of mRNA expression of subunits K_ATP channels were determined by reverse transcription and real-time polymerase chain reaction analysis. Protein expression levels were determined by the Western blot. Cardiac tissue morphology was determined using transverse 6 μm deparaffinized sections stained with picrosirius red staining. Vasorelaxation responses of isolated aortic rings and the function of Langendorff-perfused isolated hearts during ischemia-reperfusion, H₂S levels, and markers of oxidative stress were also studied. <b>Results:</b> Administration of PLP to old rats reduces cardiac fibrosis and improves cardiac function during ischemia-reperfusion and vasorelaxation responses to K_ATP channels opening. At the same time, there was a significant increase in mRNA and protein expression of SUR2 and Kir6.1 subunits of K_ATP channels, H₂S production, and reduced markers of oxidative stress. The specific K_ATP channel inhibitor-glibenclamide prevented the enhancement of vasodilator responses and anti-ischemic protection in PLP-treated animals. <b>Conclusions:</b> We suggest that this potential therapeutic effect of PLP in old animals may be a result of increased expression of K_ATP channels and H₂S production.</p>","PeriodicalId":15281,"journal":{"name":"Journal of Cardiovascular Pharmacology and Therapeutics","volume":"28 ","pages":"10742484231213175"},"PeriodicalIF":2.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72014379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increased platelet reactivity and leukocyte-platelet aggregate formation are directly involved in the progress of atherosclerosis and have been linked to ischemic events following percutaneous coronary intervention (PCI). In order to understand the relation of PLR with platelet reactivity, we assessed PLR as well as agonist-inducible platelet aggregation and neutrophil-platelet aggregate (NPA) formation in 182 acute coronary syndrome (ACS) patients on dual antiplatelet therapy with aspirin and prasugrel (n = 96) or ticagrelor (n = 86) 3 days after PCI. PLR was calculated from the blood count. Platelet aggregation was measured by multiple electrode aggregometry and NPA formation was determined by flow cytometry, both in response to ADP and SFLLRN. A PLR ≥91 was considered as high PLR based on previous data showing an association of this threshold with adverse ischemic outcomes. In the overall cohort and in prasugrel-treated patients, high PLR was associated with higher SFLLRN-inducible platelet aggregation (67 AU [50-85 AU] vs 59.5 AU [44.3-71.3 AU], P = .01, and 73 AU [50-85 AU] vs 61.5 AU [46-69 AU], P = .02, respectively). Further, prasugrel-treated patients with high PLR exhibited higher ADP- (15% [11%-23%] vs 10.9% [7.6%-15.9%], P = .007) and SFLLRN-inducible NPA formation (64.3% [55.4%-73.8%] vs 53.8% [44.1%-70.1%], P = .01) as compared to patients with low PLR. These differences were not seen in ticagrelor-treated patients.

This study assesses whether similar effects occur when interrupting renin-angiotensin system inhibitor (RASi) therapy in ADHF. Data were retrospectively analyzed from patients admitted from 2015 to 2020 with ADHF and left ventricular ejection fraction (LVEF) ≤ 40% taking RASi therapy prior to admission. Patients were excluded if they required acute inotropic therapy or mechanical circulatory support, had worsening renal function (WRF), hyperkalemia, or symptomatic hypotension on admission. The primary endpoint was readmission for heart failure, which was analyzed using Cox regression analysis. One-hundred patients were included, with 22 patients in the interruption group and 78 patients in the continuation group. Baseline characteristics for each group were similar except for older age (67.4 vs 58.9 years; P = .014) and lower systolic blood pressure (120.5 vs 132.3 mm Hg; P = .037) in the interruption group. Interrupting RASi therapy was associated with a nonsignificant increase in the primary outcome (13.6% vs 5.1%; P = .177). Patients continuing RASi therapy were discharged on higher doses (10.1 vs 17.9 mg lisinopril equivalents; P = .044). Additionally, patients with interrupted RASi therapy were more likely to be re-admitted for WRF at 30-, 60-, and 90-day increments and at any-time after discharge (P < .05 for all). Adverse effects were similar except for more frequent hypotension in the interruption group at 72 hours (40.9% vs 14.1%; P = .013) and at any time (50% vs 19.2%; P = .004). In patients admitted for acute decompensated heart failure, RASi continuation in the absence of contraindications appears safe and was associated with more optimal guideline-directed medical therapy at discharge.","PeriodicalId":15281,"journal":{"name":"Journal of Cardiovascular Pharmacology and Therapeutics","volume":"27 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42977862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to advances in skeletal muscle treatment, cardiomyopathy has emerged as a leading cause of death. Previously, nicorandil, a drug with antioxidant and nitrate-like properties, ameliorated cardiac damage and improved cardiac function in young, injured mdx mice. Nicorandil mitigated damage by stimulating antioxidant activity and limiting pro-oxidant expression. Here, we examined whether nicorandil was similarly cardioprotective in aged mdx mice. Methods and Results: Nicorandil (6 mg/kg) was given over 15 months. Echocardiography of mdx mice showed some functional defects at 12 months compared to wild-type (WT) mice, but not at 15 months. Disease manifestation was evident in mdx mice via treadmill assays and survival, but not open field and grip strength assays. Cardiac levels of SOD2 and NOX4 were decreased in mdx vs. WT. Nicorandil increased survival in mdx but did not alter cardiac function, fibrosis, diaphragm function or muscle fatigue. Conclusions: In contrast to our prior work in young, injured mdx mice, nicorandil did not exert cardioprotective effects in 15 month aged mdx mice. Discordant findings may be explained by the lack of cardiac disease manifestation in aged mdx mice compared to WT, whereas significant cardiac dysfunction was previously seen with the sub-acute injury in young mice. Therefore, we are not able to conclude any cardioprotective effects with long-term nicorandil treatment in aging mdx mice.","PeriodicalId":15281,"journal":{"name":"Journal of Cardiovascular Pharmacology and Therapeutics","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43694026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Retrospective, cross-sectional cohort analysis of data from the National Survey on Drug Use and Health, 2015-2019, based on standard measures of functioning: self-rated health, serious psychological distress, and high-risk substance use. Cohorts were veterans with respondent-reported heart disease, or at high risk of cardiovascular disease based on age/comorbidity combinations (HD/risk); nonveterans with HD/risk; and veterans without HD/risk.
