afibprevalent Prevalent Atrial Fibrillation (AF) at SHHS Visit 1

Variable created as part of the analysis for Tung et al. 2017 (PubMed ID: 28668820). Prevalent AF was defined by any of the following: a positive response to the question 'Has a doctor ever told you that you have or had atrial fibrillation'; AF identified on resting 12-lead ECG at the baseline SHHS exam; or if the parent study identified AF documented in the medical record before the SHHS baseline exam.

nsrr_bp_diastolic Diastolic blood pressure

Average resting diastolic blood pressure of two measurements collected from the upper arm in a single clinic visit. When more than two measurements were collected, the average was calculated using the second and third measurements. In cases where either of the measurements was missing, the average was calculated discarding the missing value.
