Hypertension and Vascular Risk in Very Elderly: Pp.19.214

Objectives: The prevalence of hypertension (HT) in >65 years is high, however people >80 years represent one of the most forgotten, despite the high prevalence of HT. Our objective was to determine the clinical characteristics of the population >80 years who attended our consultation. Methods: Cross-sectional study, during 2009, which included patients >65 years. We studied: demographic parameters, cardiovascular risk factors (CRF), target organ damage (TOD) and comorbidity. Statistical analyses of qualitative variables are in percentages and frequencies, numerical in standard deviation; comparison of categorical variables using X2 test and for continuous T-student test. A p value <0.05 was considered significant. Results: There was 307 patients >80 years and 418 between 65–80 years. In patients >80 years, 61.2% were men, 84.7% had hypertension, 57% CKD (GFR <60 ml/min/1,73m2), 28% cardiopathy, 13% stroke, 49.5% had at least 1 TOD, 67% had 3 or more CRF, and Charlson index was 8.97 ± 2.07. Comparing these patients with 65–80 years, we find no differences for sex, HT, smoking, diabetes and peripheral vascular disease. Patients >80 years had less obesity (p:0.0004; OR:0.57 CI95%: 0.41–0.78), dyslipidemia (p:0.00002, OR:0.53 CI95%: 0.39–0.71), however had a high prevalence of cardiopathy (cardiac insufficiency, myocardial infarction, LVH) (p:0.0002, OR:1.9 CI95%: 1.35–2.76), stroke (p:0.008, OR:1.93 CI95%: 1.17–3.18), CKD (p:0.00001, OR:2.33 CI95%: 1.72–3.15), presence at least 1 TOD (p:0.00001, OR:2.07, CI95%: 1.52–2.80). The BMI is lower (p:0.0003), but had a high number of TOD, CRF and Charlson I. (p:0.00001). Conclusions: HT is very prevalent in our population. Compared to the classic group of > 65 years they have a great number of CRF and TOD. While the magnitude of risk tends to be lower after 65 years, the absolute risk is greater because the CRF are more prevalent and frequently associated with increasing age, which has a multiplier effect. Studies are needed to selectively target this age group while existing information is variable and inconsistent.
