Compared with younger adults, older individuals are at least twice more likely to develop HTN.33 With age, arteries dilate and stiffen, neurohormonal mechanisms such as the renin‐angiotensin‐aldosterone system decline, and there is a progressive development of renal glomerulosclerosis and interstitial fibrosis, which is associated with a decline in glomerular filtration rate and reduction of other homeostatic mechanisms,1, 34, 35, 36 altogether accounting for an increased prevalence of HTN in elderly populations. The gene discussed is REN; the disease is hypertensive disorder.
