Kardiovize Brno 2030, a prospective cardiovascular health study in central Europe: Methods, baseline findings and future directions

Background: Atherosclerotic cardiovascular disease is highly prevalent in Eastern and Central Europe, where the incidence is the highest in the world. The Kardiovize Brno 2030 study was designed as a prospective cohort study to investigate the complex relationships of cardiovascular disease and outcomes with a range of biological, psychosocial, environmental, behavioral, and economic factors in an urban population of the Czech Republic. Methods: We randomly selected a 1% sample of the city of Brno residents aged 25–64 years stratified by sex and age. The study assessed traditional and novel cardiovascular disease risk factors, including sociodemographic and smoking status, physical activity, diet, depression, stress, body fat, cardio-ankle vascular index, and intima media thickness, complemented by blood tests; biological samples were stored for future analyses. Results: The study enrolled 2160 participants (54.8% women), with a mean age of 47±11.3 years. They were mostly full-time employed (75.6%) and married (62.1%). Hyperlipidemia was highly prevalent (70.7% in men, and 67.1% in women, NS). Hypertension and diabetes mellitus were more prevalent in men than in women (54.3% vs. 38. 7% and 7.1% vs. 3. 5%, respectively, P < 0.001 for both). A total of 25.3% of men and 21.9% of women smoked, whereas 20.0% and 43.0% of men and 18.1% and 26.6% of women were obese and overweight, respectively. Conclusions: Cardiovascular risk factors are highly prevalent in the city of Brno, an urban population from Central Europe. The Kardiovize Brno 2030 study will provide unique multidimensional and longitudinal cardiovascular health data from a region where epidemiological studies are scarce.
