CARDIOVASCULAR RISK IN HYPERTENSIVE PATIENTS INCLUDED IN THE IBERICAN STUDY

Abstract

Objective: The general objectives of IBERICAN are to determine the prevalence and incidence of cardiovascular risk factors in Spain, as well as cardiovascular events. The objective of the present work is to know the cardiovascular risk of hypertensive patients included in the IBERICAN Study. Design and method: IBERICAN is a longitudinal, observational, and multicenter study in which patients from 18 to 85 years of age are included in primary care consultations in Spain. The cohort obtained will be followed annually for at least 5 years. The final estimated sample is 7,000 patients. The baseline characteristics of the first 5,944 patients included are presented. Cardiovascular risk factors (diabetes, obesity, dyslipidemia, smoking, sedentary lifestyle) and cardiovascular disease (ischemic heart disease, stroke, heart failure, peripheral arterial disease) have been analysed to estimate the cardiovascular risk according to the SCORE for low risk countries. Results: 2,873 patients have hypertension (48.3%), their average age was 64.7 ± 12 years, 49.7% women, hypertension evolution time was 9.7 ± 6 years, BMI 31.1 ± 8.9 kg / m2. The prevalence of risk factors in this population is: dyslipidemia 65.8%; obesity 47.2%; sedentary lifestyle 35.4%, diabetes 30.7 and smoker 13.4%. The cardiovascular disease was in 23.8% of the patients: ischemic heart disease 10.4%; peripheral arterial disease 7%; heart failure 5.6%, and stroke 5.5%. The degree of control of blood pressure was: 56.7%. The distribution of hypertensive patients according to the risk category was: low risk 6.2%; moderate 25.8%; high 19.5% and very high risk 48.5%. 68% of hypertensive patients are at high or very high risk. Conclusions: The population of hypertensive patients in the IBERICAN study has a high prevalence of cardiovascular risk factors and cardiovascular disease. The level of risk is very high in almost half of the hypertensive and two out of three are high or very high risk.
