The standardized prevalence was 2.7% in 2022 in the region, slightly higher than that of France (2.5%).

• At the subregional level, several departments in the region had higher incidence rates. There was some heterogeneity at the subdepartmental level, particularly in certain areas of Nord and Pas-de-Calais with high incidence rates for all three conditions. The predominantly rural EPCIs in northern Aisne had high rates of ischemic heart disease in terms of incidence, prevalence, and mortality.
