PP.11.03] PREVALENCE AND CHARACTERISTICS OF THE PATIENTS WITH HYPERTENSION IN THE IBERICAN STUDY

Abstract

Objective: The general aim of IBERICAN study is to know the prevalence and incidence of cardiovascular risk factors (CVRF) and cardiovascular and renal disease (CVD) in Spain. The aim of this abstract is to know the prevalence of hypertension and its relation with CVRF, subclinical organ damage (LOD) and CVD in the population of the IBERICAN Study. Design and method: The IBERICAN Study is a longitudinal, observational, and multicentric study with subjects between 18 to 85 years of age, recruited in Primary Care and who will be follow up at least 5 years. The final sample size is estimated in 7,000 patients. We show the baseline characteristics of the patients in the first visit (n = 3,042). We analyzed patients with hypertension and their association with the presence of CVRF (diabetes, dyslipidemia, smoking and obesity), LOD (left ventricular hypertrophy, glomerular filtration <60 ml/min and albuminuria) and CVD: ischemic heart disease, heart failure, stroke, peripheral arterial disease and nephropathy. Results: The mean age in the sample was 65.4 ± 11 years, 50.5% women. The prevalence of hypertension was 47,4% (n = 1,429), and their degree control was 58.5%. The prevalence of hypertension in men was higher than women: 52.9% vs 43%, P < 0.001. Every CVRF were more frequent in hypertensive patients: dyslipidemia 66.4% vs 35.9%, p < 0.001; diabetes 30.6% vs. 8.5%, p < 0.001; obesity 44.4% vs 22.5%, p < 0.001; smoker 13.5% vs. 22.7%, p < 0.001; sedentary lifestyle 34.3% vs. 25.5%, p < 0.001. Also, the LOD were more frequent with the hypertension: HVI 8.2% vs 1.4%, p < 0.001; GFR less than 60 ml/min 13.7% vs 8.2%, p < 0.05; albuminuria 13.4% vs. 5.6%, p < 0.001. Finally, the prevalence of cardiovascular disease was higher in hypertensive patients (21.6% vs 10.2%, p < 0.0001), ischemic heart disease (10.7% vs 5.3%, p < 0.001); stroke (6.5% vs 3%, p < 0.001); peripheral arterial disease (6.4% vs 2.5%, p < 0.0001) and heart failure (4.8% vs. 1.3%, p < 0.001). Conclusions: Patients with hypertension in Primary Care have higher prevalence of cardiovascular risk factors, subclinical organ injury and established cardiovascular disease. The degree of blood pressure control is clearly improved.
