RESUMEN
Superselective adrenal arterial embolization (SAAE) appears to be beneficial in primary aldosteronism (PA) patients with lateralized aldosterone secretion (unilateral PA). As confirmed by adrenal vein sampling (AVS), nearly 40% of PA patients would be PA without lateralized aldosterone secretion (bilateral PA). We aimed to investigate the efficacy and safety of SAAE on bilateral PA. We identified 171 bilateral PA patients from 503 PA patients who completed AVS. Thirty-eight bilateral PA patients received SAAE, and 31 completed a median 12-month clinical follow-up. The blood pressure and biochemical improvements of these patients were carefully analyzed. 34% of patients were identified as bilateral PA. Plasma aldosterone concentration, plasma renin activity, and aldosterone/renin ratio (ARR) were significantly improved 24-h after SAAE. SAAE was associated with 38.7% and 58.6% of complete/partial clinical and biochemical success within a median 12-month follow-up. A significant reduction in left ventricular hypertrophy was shown in patients who obtained complete biochemical success compared with partial/absent biochemical success. SAAE was associated with a more apparent nighttime blood pressure reduction than daytime blood pressure reduction in patients with complete biochemical success. No major adverse safety events related to SAAE were reported during the intraoperative, postoperative, and follow-up periods. SAAE was associated with blood pressure and biochemical improvements in part of bilateral PA and appeared safe. The biochemistry success was accompanied by improved cardiac remodeling and a more prominent decrease in nocturnal blood pressure. This study was part of a trial registered with the Chinese Clinical Trial Registry, number ChiCTR2100047689.

Background: Studies have shown that percutaneous coronary intervention (PCI) is considered as the essential therapeutic strategy for the patients with ST-segment elevation myocardial infarction (STEMI). However; no-reflow could still occur in a few patients after PCI. Studies have reported that biomarkers related to no-reflow pathogenetic components could play a prognostic role in the prediction phenomenon. Hence, this study explored the establishment of nomogram model for predicting the occurrence of no-reflow phenomenon after PCI using the lncRNA TUG1/miR-30e/NPPB biomarkers in patients with STEMI after PCI. Methods: In this observational study, a total of 76 STEMI patients who underwent emergency PCI between January 2018 and December 2021were included. The patients after PCI, were divided into reflow (n=44) and no-reflow groups (n=32). The demographic, environmental and clinical risk factors were assessed and analysed between the groups. Quantitative RT-PCR was used to detect TUG1, miR-30e, and NPPB messenger RNA (mRNA) expression levels in the plasma of patients after PCI. Bioinformatic methods were used to predict the interaction of the plasma TUG1/miR-30e/NPPB axis. The risk factors in the no-reflow group were screened using a logistic-regression analysis, and a nomogram prediction model was constructed and validated. Subsequently, a gene set enrichment analysis revealed the function of lncRNA TUG1. Results: Plasma lncRNA TUG1 and NPPB were more highly expressed and miR-30e was more lowly expressed in the no-reflow group than the normal-reflow group (P<0.001). A negative correlation was observed between lncRNA TUG1 and miR-30e, and between miR-30e and NPPB. However, a positive correlation was observed between lncRNA TUG1 and NPPB mRNA. The bioinformatics analysis predicted multiple binding sites on the lncRNA TUG1 and miR-30e. LncRNA TUG1 [odds ratio (OR): 0.163, 95% confidence interval (CI): 0.021-0.944] and hs-CRP (OR: 2.151, 95% CI: 1.536-3.974) found to be as independent predictors. The C-index of this prediction model was 0.982 (95% CI: 0.956-1.000). Conclusions: TUG1 could function as an effective biomarker for no-reflow among patients with STEMI after PCT and the proposed nomogram may provide information for individualized treatment in patients with STEMI.
