Abstract 438: Association between Insomnia and Use of BP-lowering Drugs in hypertensive Patients: a Cross-sectional Cohort Study
Purpose: Insomnia and short sleep duration have been associated with increased prevalence, incidence and severity of hypertension. However, the relationship between insomnia and use of different antihypertensive drug classes has not been ascertained yet.
Methods: 371 hypertensive patients at their first visit in a tertiary Hypertension Outpatient Unit were enrolled. Insomnia Severity Index (ISI), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAY-Y2) were administered. Insomnia was defined as ISI>8, depressive symptoms as BDI>10, trait anxiety as STAI -Y2>40. Patients with self-reported sleep apneas or snoring (n=29) or with incomplete data (n=12) were excluded.
Results: Data from 330 patients were analyzed (males 51%, mean age 57±13 years, antihypertensive treatment 84%, previous CV events 9%, diabetes 7%, obesity 24%, smoking 13%, hypercholesterolemia 67%). Insomniacs (n=70, 21%) were older than non-insomniacs (60±11 vs 56±13 years, p=0.02); female gender (62 vs 46%, p=0.01), anxiety (68 vs 34%, p<0.0001) and depressive symptoms (30 vs 6%, p<0.0001) were more prevalent in insomniacs. Insomniacs were treated with higher number of antihypertensive drugs (1.8±1.0 vs 1.5±1.0, p=0.04) and more frequently with angiotensin-receptor-blockers (ARBs, 49 vs 31%, p=0.009) and diuretics (50 vs 28%, p=0.0007), whereas the use of other drug classes was similar.
In a multiple logistic regression analysis, adjusted for cardiovascular and psychiatric variables, ARBs use (OR 2.4, CL95% 1.1-5.2), depressive symptoms (OR 3.2, CL95%1.2-8.7) and anxiety (OR 2.9, CL95%1.4-6.1) were associated with a higher probability of insomnia.
Conclusions: This cross-sectional analysis suggests that ARBs use may be associated with insomnia in a cohort of hypertensive patients
