STRKHEMO - Hemorrhagic Stroke Col 4 Usage Notes: Defined as a Stroke where the diagnosis question indicates a hemorrhagic stroke. With the completion of retrospective adjudications for stroke cases among Self Report Cohort (SRC) participants, hemorrhagic stroke is now adjudicated for all CT and OS participants through Ext2. Strokes from cause of death, Form 121 and early versions of 132 were not able to determine Hemorrhagic/Ischemic classification. Includes inpatient strokes for the core WHI study and inpatient and outpatient strokes after the core study closeout.
STRKISCH - Ischemic Stroke Col 5 Usage Notes: Defined as a Stroke where the diagnosis question indicates an iscemic stroke. With the completion of retrospective adjudications for stroke cases among Self Report Cohort (SRC) participants, ischemic stroke is now adjudicated for all CT and OS participants through Ext2. Strokes from cause of death, Form 121 and early versions of 132 were not able to determine Hemorrhagic/Ischemic classification. Includes inpatient strokes for the core WHI study and inpatient and outpatient strokes after the core study closeout.
STROKE - Stroke Col 6 Usage Notes: Defined as the first occurrence of Stroke or a Death due to Cerebrovascular. With the completion of retrospective adjudications for stroke cases among Self Report Cohort (SRC) participants, stroke is now adjudicated for all CT and OS participants through Ext2. In order to be able to classify strokes, WHI uses central adjudications where available. See the DEATH and DEATHSRC variables for details about the death adjudication process. Includes inpatient strokes for the core WHI study and inpatient and outpatient strokes after the core study closeout.
STROKEDX - Stroke diagnosis Col 7 Usage Notes: Value 6 was only on form 121 and early versions of form 132. Strokes with a diagnosis code of 6 were unable to be classified as Hemorrhagic or Ischemic.
STROKEPROC - Stroke occurred during or resulted from a procedure Col 8 Usage Notes: Not collected on early versions of F132. A stroke is defined as procedure-related if it occurs within 24 hours after any procedure or within 30 days after a cardioversion or invasive cardiovascular procedure.
STROKEOUTPAT - F132 Stroke diagnosed or managed as outpatient Col 9 Was the stroke diagnosed or managed as an outpatient?* *The outpatient setting includes any emergency department or observation unit, short hospital stays of less than 24 hours duration or a direct admission to a rehab facility without an associated admission to an acute care hospital.

STROKETOAST - TOAST Classification Col 11 Trial of Org 10172 in Acute Stroke Treatment (TOAST) Classification Usage Notes: A "probable" diagnosis is made if the clinical findings, neuroimaging data, and results of diagnostic studies are consistent with one subtype and other etiologies have been excluded. A "possible" diagnosis is made when the clinical findings and neuroimaging data suggest a specific subtype but other studies are not done.
STROKEBASE - Stroke diagnosis based on Col 12
STROKE28DEATH - Hospitalized stroke within 28 days of death Col 13 If stroke fatal: Hospitalized stroke within 28 days of death

CARBHOSP - Carotid artery disease based on hosp discharge Col 19 Carotid artery disease based on: Symptomatic disease with carotid artery disease listed on the hospital discharge summary Usage Notes: Collected on all versions of form 121, only collected on form 132 after WHI closeout.
CARBABNORMAL - Carotid artery disease based on abnormal findings Col 20 Carotid artery disease based on: Symptomatic disease with abnormal findings (>= 50% stenosis) on carotid angiogram, MRA, or Doppler flow study Usage Notes: Collected on all versions of form 121, only collected on form 132 after WHI closeout.
