Background: Atherosclerosis-related adverse events are commonly observed even in conditions with low cardiovascular (CV) risk. Longitudinal data regarding the association of normal systolic blood pressure maintenance (SBPmaintain) with coronary plaque volume changes (PVC) has been limited in adults without traditional CV disease. Hypothesis: Normal SBPmaintain is important to attenuate coronary atherosclerosis progression in adults without baseline CV disease. Methods: We analyzed 95 adults (56.7 ± 8.5 years; 40.0% men) without baseline CV disease who underwent serial coronary computed tomographic angiography with mean 3.5 years of follow-up. All participants were divided into two groups of normal SBPmaintain (follow-up SBP < 120 mm Hg) and ≥elevated SBPmaintain (follow-up SBP ≥ 120 mm Hg). Annualized PVC was defined as PVC divided by the interscan period. Results: Compared to participants with normal SBPmaintain, those with ≥elevated SBPmaintain had higher annualized total PVC (mm3/year) (0.0 [0.0–2.2] vs. 4.1 [0.0–13.0]; p <.001). Baseline total plaque volume (β =.10) and the levels of SBPmaintain (β =.23) and follow-up high-density lipoprotein cholesterol (β = −0.28) were associated with annualized total PVC (all p <.05). The optimal cutoff of SBPmaintain for predicting plaque progression was 118.5 mm Hg (sensitivity: 78.2%, specificity: 62.5%; area under curve: 0.700; 95% confidence interval [CI]: 0.59–0.81; p <.05). SBPmaintain ≥ 118.5 mm Hg (odds ratio [OR]: 4.03; 95% CI: 1.51–10.75) and baseline total plaque volume (OR: 1.03; 95% CI: 1.01–1.06) independently influenced coronary plaque progression (all p <.05). Conclusion: Normal SBPmaintain is substantial to attenuate coronary atherosclerosis progression in conditions without established CV disease.
