PREVALENCE OF TARGET ORGAN DAMAGE IN PATIENTS WITH TYPE 2 DIABETES MELLITUS IN IBERICAN STUDY

Abstract

Objective: The general aim of IBERICAN study is to know the prevalence and incidence of cardiovascular risk factors and cardiovascular and renal disease in Spain. The aim of this abstract is to know the prevalence of subclinical target organ damage (TOD) and type 2 of Diabetes mellitus (T2DM) in 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 (PC) and who will be follow up at least 10 years. The final sample size is estimated in 8,066 patients. We show the baseline characteristics of the patients in the first visit (n = 8,066). To define the TOD, we consider the ESH 2013 Guide criteria: pressure pulse in aged > 60 mmHg, ankle/brachial index < 0.9, microalbuminuria: albumin/creatinine ratio (between 30 - 299 mg/g), glomerular filtration (CDK-EPI < 60 ml/min), left ventricular hypertrophy (electrocardiogram or ECHO). Results: 1,434 patients had T2DM (20.1%), 56.4% men. 44.8% of patients with T2DM had TOD. Of the patients with TOD, the mean BMI was 31.7 ± 9.6 Kg/m2. By type of TOD: pulse pressure at > 60 mmHg: 29.2%; ankle/brachial index < 0.9: 3.0%; microalbuminuria: 17.0%; left ventricular hypertrophy: 7.0%. The prevalence of cardiovascular risk factors in patients with T2DM and TOD compared to non-TOD was: Hypertension 84.8% vs 68.4%, p< 0.001; dyslipidemia 78.2% vs 71.6%, p < 0.01; obesity 52.0% vs 49.7% p = 0.376; alcohol consumption 17.0% vs 15.2% p = 0.369; smoking 12.4% vs 14.7%, p = 0.202; sedentary lifestyle 38.5% vs 33.7%, p = 0.061. Conclusions: The prevalence of TOD in patients with T2DM in primary care is high, half of the patients. By type of TOD, elevated pulse pressure in the elderly and microalbuminuria were the most prevalent. Arterial hypertension and dyslipidemia were more prevalent in patients with TOD.
