Differential Diagnosis and Treatment Rates Between Systolic and Diastolic Hypertension in Young Adults: A Multidisciplinary Observational Study. Issue 11 (13th June 2015) - Johnson, Heather M.
Abstract Differential rates of diagnosis and treatment by hypertension (HTN) type may contribute to poor HTN control in young adults. The objective of this study was to compare rates of receiving a hypertension diagnosis and antihypertensive agent among young adults with (1) isolated systolic, (2) isolated diastolic, and (3) combined systolic/diastolic HTN. A retrospective analysis was conducted in patients aged 18 to 39 years (n=3003) with incident HTN. Kaplan–Meier survival and Cox proportional hazards analyses were performed. Only 56% with isolated systolic HTN received a diagnosis compared with 63% (systolic/diastolic); 32% with isolated systolic HTN received an initial antihypertensive compared with 52% (systolic/diastolic). Compared with patients with systolic/diastolic HTN, those with isolated systolic HTN had a 50% slower diagnosis rate (hazard ratio [HR], 0.50; 95% confidence interval [CI], 0.41–0.60) and those with isolated diastolic HTN had a 26% slower rate (HR, 0.74; CI, 0.60–0.92). Patients with isolated systolic HTN had 58% slower medication initiation (HR, 0.42; CI, 0.34–0.51) and those with isolated diastolic HTN had 31% slower rates (HR, 0.69; CI, 0.55–0.86). Young adults with isolated systolic HTN have lower diagnosis and treatment rates.
