Diastolic blood pressure predicts coronary plaque volume in patients with coronary artery disease.

•Coronary plaque volume was measured by coronary computed tomographic angiography.•Coronary plaque volume was higher at higher levels of diastolic blood pressure.•In contrast, systolic blood pressure did not predict coronary plaque volume.•Diastolic blood pressure ≤68 mm Hg had the lowest coronary plaque volume.•Reduction of diastolic blood pressure to ≤68 mm Hg may prevent plaque progression.
