ASSOCIATION OF OFFICE AND RESIDENTIAL BLOOD PRESSURE, PRESSURE CONTROL RATE AND NUMBER OF ANTI-HYPERTENSIVE AGENTS IN A BRAZILIAN MULTICENTRIC

Abstract

Objective: Compare systolic (SBP) and diastolic (DBP) blood pressure, control rate, number of antihypertensive drugs (AH) and age group among hypertensive patients. Design and method: Analytical cross-sectional study, using the TeleMRPA platform database. Variables used: sex, age, SBP and DBP obtained by HBPM, office BP (PAc) and number of AH: 1 monotherapy, double, triple combination or with four or more. Elderly > = 60 years old and non-elderly <60 years old were considered. The chi-square test was used to compare proportions and the t-student test to compare means, 95% confidence interval and significance level p<0.05. Results: 25,543 participated, 54.6% elderly (n = 13938; p<0.001), more women in the elderly group (66.9%) than among non-elderly (58.6% - p<0.001). The elderly group (71±8.0 years old) had a mean SBP of 136.7(±21.3) mmHg and DBPc of 80.6(±11.8) mmHg and MRPA SBP 129.0(±16) .0) mmHg and DBP 76.4(±9.6) mmHg. The non-elderly group (47±8.6 years old) had SBP of 129.6(±18.4) mmHg and DBPc of 86.4(±11.5) mmHg and by MRPA SBP 122.9(±14.6) mmHg and DBP 81.5(±9.5)mmHg; significant mean differences (p<0.001) in both groups. Controlled BP rate (HBPM) among the elderly was 56.2% and among non-elderly 43.8%. The number of antihypertensive drugs in the elderly group was 38.2%, 38%, 18.5% and 5.3% for monotherapy, double, triple combination or with four or more AH respectively; among non-elderly people it was 47.8%, 36.6%, 12.3% and 3.3% (p<0.001). Among the elderly, the BP control rate (HBPM) was 43.8% in monotherapy and 35.9% in four or more combinations (p<0.001); among the non-elderly, the rate of BP control (HBPM) was 41.7% in monotherapy and 25.8% in combination with four or more drugs (p<0.001). Conclusions: The elderly group had higher systolic values, both in the office and at home, and lower diastolic values, and a higher frequency of antihypertensive therapy in combination. The BP control rate was higher among the elderly and the greater the number of drugs used, the lower the BP control rate in both groups.
