BACKGROUND Growing literature linking unconventional natural gas development (UNGD) to adverse health has implicated air pollution and stress pathways. Persons with heart failure (HF) are susceptible to these stressors. OBJECTIVES This study sought to evaluate associations between UNGD activity and hospitalization among HF patients, stratified by both ejection fraction (EF) status (reduced [HFrEF], preserved [HFpEF], not classifiable) and HF severity. METHODS We evaluated the odds of hospitalization among patients with HF seen at Geisinger from 2008 to 2015 using electronic health records. We assigned metrics of UNGD activity by phase (pad preparation, drilling, stimulation, and production) 30 days before hospitalization or a frequency-matched control selection date. We assigned phenotype status using a validated algorithm. RESULTS We identified 9,054 patients with HF with 5,839 hospitalizations (mean age 71.1 ± 12.7 years; 47.7% female). Comparing 4th to 1st quartiles, adjusted odds ratios (95% confidence interval) for hospitalization were 1.70 (1.35 to 2.13), 0.97 (0.75 to 1.27), 1.80 (1.35 to 2.40), and 1.62 (1.07 to 2.45) for pad preparation, drilling, stimulation, and production metrics, respectively. We did not find effect modification by HFrEF or HFpEF status. Associations of most UNGD metrics with hospitalization were stronger among those with more severe HF at baseline. CONCLUSIONS Three of 4 phases of UNGD activity were associated with hospitalization for HF in a large sample of patients with HF in an area of active UNGD, with similar findings by HFrEF versus HFpEF status. Older patients with HF seem particularly vulnerable to adverse health impacts from UNGD activity.

宾夕法尼亚州心力衰竭的非常规天然气开发和住院治疗

背景越来越多的文献将非常规天然气开发 (UNGD) 与不利的健康联系起来,其中涉及空气污染和压力途径。患有心力衰竭 (HF) 的人容易受到这些压力源的影响。目的 本研究旨在评估 UNGD 活动与 HF 患者住院之间的关联,根据射血分数 (EF) 状态(降低 [HFrEF],保留 [HFpEF],不可分类)和 HF 严重程度进行分层。方法 我们使用电子健康记录评估了 2008 年至 2015 年在 Geisinger 就诊的 HF 患者的住院几率。我们在住院前 30 天或频率匹配的对照选择日期按阶段(垫准备、钻孔、刺激和生产)分配 UNGD 活动的指标。我们使用经过验证的算法分配了表型状态。结果我们确定了 9, 054 名 HF 患者,其中 5,839 次住院(平均年龄 71.1 ± 12.7 岁;47.7% 女性)。比较第 4 和第 1 个四分位数,调整后住院的比值比(95% 置信区间)为 1.70(1.35 至 2.13)、0.97(0.75 至 1.27)、1.80(1.35 至 2.40)和准备垫的 1.62(1.07)分别是钻井、增产和生产指标。我们没有发现 HFrEF 或 HFpEF 状态对效果的影响。大多数 UNGD 指标与住院的关联在基线时心衰更严重的患者中更强。结论 在活动性 UNGD 区域的大量 HF 患者样本中,UNGD 活动的 4 个阶段中的三个阶段与 HF 住院相关,HFrEF 与 HFpEF 状态的结果相似。老年 HF 患者似乎特别容易受到 UNGD 活动的不利健康影响。
