The standardized prevalence in 2022 was 5.3% in the region, slightly lower than that of France (5.5%). The standardized mortality rate (2020–2022) was also slightly lower in the region than the national rate (57 vs. 59 per 100,000 inhabitants, respectively).

• Between 2021 and 2023, the standardized incidence rate of patients hospitalized for heart failure in Nouvelle-Aquitaine was lower than that of France (312 vs. 344 per 100,000 inhabitants), with an average of 18,045 patients hospitalized per year in the region. The standardized prevalence was 2.4% in 2022 in the region, comparable to that of France (2.5%). The standardized mortality rate (2020–2022) in the region, however, was higher than that of France (51 vs. 46 per 100,000 inhabitants, respectively).

• Between 2021 and 2023, the standardized incidence rate of patients hospitalized for stroke in Nouvelle-Aquitaine was close to that of France (234 vs. 231 per 100,000 inhabitants, respectively), with an average of 12,986 patients hospitalized per year in the region. The standardized prevalence in 2022 was 2.0% in the region, comparable to the national prevalence (2.0%). The standardized mortality rate (2020–2022) in the region was comparable to that of France (60 vs. 58 per 100,000 inhabitants, respectively).

• At the subregional level, several departments in the region had higher incidence rates than those of the region and France depending on the condition: specifically in Charente and Haute-Vienne for ischemic heart disease, in Dordogne and Creuse for heart failure, and in Pyrénées-Atlantiques and Lot-et-Garonne for strokes. Mortality rates were higher than the regional rates for all three conditions in Creuse and Dordogne, and for heart failure in Haute-Vienne. Heterogeneity was also observed at the sub-departmental level.
