Data were generated through a structured interpretive review of five European cardiovascular policy documents, retrieved from their issuing institutions between March and April 2026. Each document was reviewed in full, with relevant sections (strategic objectives, implementation plans, delivery mechanisms, and rehabilitation provisions) assessed against three predefined requirements concerning behavioural specification: (1) explicit articulation of behavioural mechanisms; (2) distinction between processes of initiation and maintenance; and (3) cross-actor behavioural alignment. For each requirement, documents were classified as Present, Partial, or Absent, accompanied by extracted textual evidence and interpretive commentary. The Czech and Romanian plans were reviewed using digital translation, with author verification of key sections to ensure accurate interpretation. Assessments were conducted by the authors as a structured interpretive analysis; formal inter-rater reliability coding was not undertaken.
