clinical data category subset clinical event record cardiovascular event record A clinical event record that documents an occurrence involving the heart or blood vessels in a patient at a specified time point or during a specified time interval, typically an acute episode or outcome relevant to cardiovascular health. Use for outcome/event variables such as myocardial infarction, stroke, heart failure hospitalization, cardiac arrest, revascularization events, cardiovascular death, or composite endpoints (e.g., MACE) when represented as occurrences. Do not use for chronic diagnoses recorded as ongoing states (classify those as condition), nor for procedures or medication exposures unless the dataset encodes them explicitly as events. If you want a clean child hierarchy under this class, common subclasses are: myocardial infarction event stroke event heart failure hospitalization event revascularization event cardiovascular death event major adverse cardiovascular event (composite) cardiovascular event http://snomed.info/id/405617006 https://w3id.org/CMEO
