This study aims to determine whether dietary sodium restriction counseling decreases nocturnal voiding frequency in cardiology patients with concomitant nocturia. Patients who had established care at a cardiology clinic from 2015 to 2018 reporting ≥1 average nocturnal void(s) underwent a comprehensive sodium intake interview by their cardiologist, who provided them with individualized strategies for dietary sodium reduction and assessed adherence at follow-up. Average nocturnal voiding frequency and dietary adherence were documented in the medical record. A nocturia database was compiled for retrospective analysis. A total of 74 patients were included. Patients considered to be adherent with dietary sodium restriction at follow-up (n = 56) demonstrated a decrease in median nocturia frequency (2.5 [2.3-3.0] vs 1.0 [1.0-2.0] voids, P < .001). Among nonadherent patients (n = 18), median nocturia frequency did not significantly change from baseline to follow-up (2.0 [1.5-3.8] vs 2.0 [1.5-4.8] voids, P = .423). Median changes were significantly different between the adherent and nonadherent groups (P < .001). Examination of second follow-up available from 37 patients showed a continued effect. In conclusion, adherence with dietary sodium counseling appears to improve nocturia. Accordingly, dietary modification may represent an important adjunct therapy to lifestyle and pharmacologic interventions for decreasing nocturia frequency. Reduction in nocturnal voiding frequency may also reflect an additional benefit of dietary sodium restriction in accordance with best practice standards for cardiovascular disease.
这项研究旨在确定饮食钠限制咨询是否会减少伴有夜尿症的心脏病患者的夜间排尿频率。2015 年至 2018 年期间，在心脏病诊所接受治疗并报告平均夜间排尿次数≥1 次的患者接受了他们的心脏病专家进行的综合钠摄入量访谈，医生为他们提供了个性化的饮食钠减少策略，并在随访时评估了依从性。平均夜间排尿频率和饮食依从性都记录在病历中。为了回顾性分析，还建立了一个夜尿症数据库。共有 74 名患者入选。在随访时被认为遵守饮食钠限制的患者（n=56）表现出夜间多尿频率中位数降低（2.5[2.3-3.0]比 1.0[1.0-2.0]次排尿，P<0.001）。在不遵守的患者中（n=18），夜间多尿频率从基线到随访时没有显著变化（2.0[1.5-3.8]比 2.0[1.5-4.8]次排尿，P=0.423）。两组之间的中位数变化差异具有统计学意义（P<0.001）。对 37 名患者的第二次随访结果进行检查，发现这种效果仍在持续。总之，遵守饮食钠咨询似乎可以改善夜尿症。因此，饮食改变可能代表一种重要的辅助治疗方法，可与生活方式和药物干预联合用于减少夜尿症频率。夜间排尿频率的减少也可能反映了根据心血管疾病最佳实践标准限制饮食钠摄入的额外益处。
