• The prescription-based definition is at least one prescription over one year for a cardiovascular drug, excluding propranolol (Anatomic Therapeutic Chemical [ATC] classification system for drugs = B01A, C01A, C01B, C01CA17, C01D, C02AA, C02AB, C02C, C02D, C02L, C03, C04AD, C05BA, C07AA01, C07AA02, C07AA03, C07AA04, C07AA06, C07AA07, C07AA12, C07AB, C07AG, C07B, C07C, C08, C09, C10).

For cardiovascular condition, excluding cerebrovascular (e.g. stroke) or vascular conditions:

• The diagnosis-based definition is the above diagnosis-based definition, but excluding cerebrovascular/vascular diagnoses: (ICD-9-CM = 430-448).
