Prevalence Of Cardiovascular Disease According To The Time Of Evolution Of Diabetes In Patients Included In The Iberican Study

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 cardiovascular disease according to the time of evolution of diabetes. 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 followed 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). The evolution time of diabetes was classified into three categories (<5 years, 5–10 years y > 10 years) that divided the sample into 34,1%, 31,4% y 34,5% of the patients. Results: The prevalence of diabetes was 19% (n = 572) and the mean evolution time was 9.1 ± 6.2 years. The prevalence of cardiovascular disease was higher in patients with longer duration of diabetes (27.0% vs 19.0% vs 32.9%, p = 0.008). The most important diseases were heart failure (5.7% vs 2.2% vs 8.7%, p = 0.023), retinopathy (0.0% vs. 0.0% vs 2.3% P = 0.025), peripheral arterial disease (7.0% vs 3.3% vs 13.1%, p = 0.001). Other ischemic diseases as stroke (3.5% vs 6.7% vs. 7.8%, p = 0.266), ischemic heart disease (18.8% vs 32.8% vs. 48.4%, p = 0.270) or atrial fibrillation (8.4% vs 5.5% vs 12.2%, p = 0.061), did not reach statistical significance. Conclusions: The diabetic patients with a greater evolution time of the disease presented a higher prevalence of cardiovascular disease, although only heart failure, retinopathy and arterial disease reached statistically significant differences. We should analyze with a larger sample if this association is maintained.
