The present obesity epidemic particularly affects African-American women. Whether the obesity epidemic will alter the hypertension phenotype in African-American women is entertained.
The prevalence of morbid obesity is steadily increasing in African-American women, who are prone to developing hypertension (HTN) even in the absence of obesity. The obesity-associated hypertension phenotype is characterized by marked sympathetic nervous system activation and resistance/refractoriness to antihypertensive therapy. Weight loss achieved through lifestyle interventions and pharmacotherapy has a modest and rarely sustained antihypertensive effect. In contrast, bariatric surgery has a sustained antihypertensive effect, as evidenced by normalization of hypertension or lessening of antihypertensive therapy. The prevalence of HTN and its obesity-associated phenotype is likely to increase in African-American women over the next decades. Obese African-American women may be increasingly referred for bariatric surgery when hypertension remains uncontrolled despite lifestyle interventions and pharmacological therapy for weight loss and blood pressure (BP) control.
目前肥胖症尤其影响非裔美国女性。肥胖症是否会改变非裔美国女性的高血压表型是值得探讨的。
病态肥胖症在非裔美国女性中的患病率稳步上升,即使没有肥胖症,她们也容易患上高血压(HTN)。与肥胖相关的高血压表型的特征是明显的交感神经系统激活以及对降压治疗的抵抗/无反应性。通过生活方式干预和药物治疗实现的体重减轻仅具有适度的、很少能持续的降压作用。相比之下,减肥手术具有持续的降压作用,这表现在高血压的正常化或减少降压治疗。在未来几十年中,非裔美国女性中 HTN 的患病率及其与肥胖相关的表型可能会增加。当生活方式干预和减肥及血压(BP)控制的药物治疗未能控制高血压时,肥胖的非裔美国女性可能会越来越多地被推荐进行减肥手术。
