Abstract P401: Time Trend of Cardiovascular Diseases Prevalence in The Italian Adult Population: The Italian Health Examination Survey
Background: Despite cardiovascular diseases (CVD) are the leading causes of death and hospitalization in nearly all countries in Europe, there are paucity, weak quality and comparability of data. The periodic Health Examination Survey (HES) represents in Italy the major source of information on CVD at national level thanks to the adoption of standardized methodologies throughout the country. The aim is to present differences in trends of CVD prevalence by gender in the Italian adult population from 1998 to 2008.
Methods: Randomized population samples stratified by age and sex were examined. In 1998, 9,712 men and women aged 35–74 years were enrolled in all Italian regions; ongoing screening started in 2008 is enrolling 9,020 persons. A standardized questionnaire investigates cardiovascular disease and pharmacological treatments. The anamnesis is positive when clinical diagnosis has been made by a physician. Electrocardiograms read in Minnesota code are also performed and used to define previous myocardial infarction.
Results: Data are from 12 regions in the North, Center, and South of Italy: 3,704 men and women in 1998 and 3,479 persons in 2008 are compared. In men, prevalence of cerebrovascular events decreases from 1.5% (95% confidence interval: 1.0-1.9%) in 1998 to 0.6 (0.3–0.9%) in 2008; in women, prevalence results stable: 0.9% in 1998 (0.5–1.3%) and 0.7% in 2008 (0.4–1.1%). Prevalence of myocardial infarction results stable both in men and women: in 1998, 1.9% in men (1.4–2.4%) and 0.6% in women (0.3–0.9%), and in 2008, 2.0% (1.4-2.7%) and 0.6% (0.3-0.9%) respectively; angina pectoris results stable as well: in 1998, 2.2% in men (1.7-2.8%) and 3.9% in women (3.1-4.6%), and in 2008, 3.2% (2.5-4.0%) and 4.5% (3.6-5.4%) respectively. Prevalence of by-pass or angioplasty surgery increases in men: 2.4% (1.8-3.0%) in 1998, and 4.5% (3.6-5.4%) in 2008; in women increasing is not significant: from 0.2% (0.0-0.4%) in 1998 to 0.7% (0.3-1.1%) in 2008. Stratifying data by geographical area (North, Center, South and Island) all comparisons become not significant; in men only, cerebrovascular decreasing and by-pass or angioplasty surgery increasing trends tend to be confirmed in all three areas.
Conclusions: Trends between 1998 and 2008 decrease in cerebrovascular events and increase in prevalence of by-pass or angioplasty surgery, especially in men. Stable prevalence resulted for myocardial infarction and angina pectoris. Cerebrovascular decreasing trend is in line with smoking prevalence and mean of blood pressure decreasing in the country. Further analyses considering data from all Italian regions are needed to confirm results.
