Accordingly, we aimed to reveal Holter-guided electrocardiographic criteria to predict the beta-blocker responder ones of PVCs. A total of 89 patients who had pre- and post-treatment Holter electrocardiogram recordings and fulfilled the inclusion criteria were retrospectively included in the study. Holter recordings were screened for heart rate variability, number of PVCs, heart rate, pre- and postcoupling intervals (CIs) in 3 different time intervals (24:00-08:00 am , 08:00 am -16:00 pm and 16:00 pm -24:00). Forty-three patients were defined as beta-blocker responder group with respect to 70% decrease in PVCs burden. Heart rate variability analysis revealed that there were not statistically significant differences between beta-blocker responder and nonresponder groups. CI ratio [(post-PVC CI + pre-PVC CI)/pre-PVC CI] of responder and nonresponder groups in 24.00 to 8.00 am time interval was statistically different (3.19 vs. 2.91, P = 0.006, respectively). Logistic regression analysis revealed that CI ratios of the PVCs during the 24:00-08:00 am intervals have significantly associated with the beta-blocker responsiveness for PVCs (odds ratio, 9.54; 95% confidence interval, 1.89-48.7; P value: 0.006). Nighttime increased CI ratio, that is, shorter CI time has been found to be an independent predictor of beta-blocker response against PVCs. Therefore, beta-blockers may be preferably recommended for PVCs, especially in those with shorter CI or increased CI ratio.</p>","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":"364-368"},"PeriodicalIF":2.6,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527783","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}

Numerous pathophysiological factors underlie TRH, including endothelin-1, which until recently no approved treatments targeted. Endothelin-1 exhibits multiple actions through binding to ETA and ETB receptors. Vasoconstriction of the vascular smooth muscle occurs when endothelin-1 binds ETA and ETB, however; vasodilation of endothelial cells also occurs through activation of ETB. Currently available endothelin receptor antagonists (ERA) were only approved for pulmonary hypertension until 2024 when the Food and Drug Administration approved aprocitentan as the first ERA for hypertension treatment in combination with other antihypertensives. The approval of aprocitentan occurred following the publication of the phase 3 PRECISION trial that compared aprocitentan versus placebo for patients with \"true\" TRH. Aprocitentan 12.5 mg exhibited a placebo-adjusted reduction in sitting systolic and diastolic blood pressure of 3.8/3.9 mmHg at 4 weeks of treatment. A dose-dependent increase in peripheral edema and a small reduction in hemoglobin due to hemodilution were greater in the aprocitentan-treated patients. Animal study data from past endothelin receptor antagonists showed this class of agents may lead to birth defects and was the basis for aprocitentan's black-box warning.

Therefore, in this study, the effect of roxadustat on vascular tone was examined using rat thoracic aortas and superior mesenteric arteries according to the organ chamber method. Roxadustat relaxed the thoracic aorta in the presence or absence of vascular endothelium, but the degree of vascular relaxation was attenuated by endothelium denudation, indicating that the majority of vasorelaxation caused by roxadustat is endothelium-dependent. Pretreatment with a nitric oxide (NO) synthase inhibitor (i.e., NG-nitro-L-arginine-methyl ester), a soluble guanylate cyclase (sGC) inhibitor (i.e., 1H-[1,2,4] oxadiazolo-[4,3-a]quinoxaline-1-one), and a bradykinin B2 receptor inhibitor (i.e., icatibant) significantly weakened roxadustat-induced vasorelaxation. In addition, roxadustat treatment of endothelium intact vascular rings increased mildly NO metabolites. When the direct effects of roxadustat on vascular smooth muscle were examined, various selective potassium channel inhibitors markedly diminished roxadustat-induced vasorelaxation in vascular endothelium-denuded rings. Moreover, roxadustat significantly inhibited angiotensin Ⅱ- and phenylephrine-induced vasocontraction, regardless of the presence of vascular endothelium. Not only the thoracic aorta, roxadustat relaxed the superior mesenteric artery, a smaller vessel. These results suggest that roxadustat-induced vasorelaxation of the thoracic aorta involves activation of endothelial NO synthase through bradykinin B2 receptors and the subsequent NO/sGC pathway.
