Insights
Prior blood pressure levels, not just current ones, significantly predict cardiovascular disease risk. This finding emphasizes the importance of historical blood pressure readings in cardiovascular risk assessment.
Area of Science:
- Cardiology
- Epidemiology
- Preventive Medicine
Background:
- Elevated blood pressure (BP) is a major risk factor for cardiovascular disease (CVD).
- Evidence suggests that past BP levels may be crucial for predicting future CVD events.
- Understanding the long-term impact of BP on CVD risk is vital for effective prevention strategies.
Purpose of the Study:
- To analyze the determinants of cardiovascular disease (CVD) risk, focusing on the predictive power of antecedent versus current blood pressure (BP).
- To compare the relative importance of prior BP levels and current BP in CVD risk prediction models.
Main Methods:
- Analysis of data from 3344 participants in the Offspring Framingham Heart Study.
- Development of Cox proportional hazards models to predict 20-year CVD risk.
- Inclusion of traditional CVD risk factors, current systolic BP, and antecedent BP in statistical models.
Main Results:
- Current systolic BP was a significant predictor of CVD risk (HR=1.09 per 10 mm Hg).
- Antecedent BP was a stronger predictor of CVD risk (HR=1.19) than current BP when analyzed separately.
- In a model with both current and antecedent BP, antecedent BP remained significant (HR=1.18), while current BP lost statistical significance (HR=1.01).
Conclusions:
- Antecedent blood pressure levels demonstrate a significantly stronger association with the risk of cardiovascular disease compared to current blood pressure levels.
- Historical BP measurements are critical components for accurate CVD risk prediction.
- Clinical risk assessment models should consider incorporating antecedent BP to enhance predictive accuracy.
Abstract:
Elevated blood pressure (BP) is associated with greater risk of cardiovascular disease (CVD), and evidence suggests that prior BP levels may be at least as important as current BP in prediction models. We analyzed the determinants of CVD risk in Offspring Framingham Heart Study participants (n = 3344). The baseline Cox model included the traditional risk factors and current systolic BP to predict 20-year risk of CVD (643 events). Current systolic BP was significant, and the associated hazard ratio was 1.09 for 10 mm Hg (confidence interval [CI] 95%: 1.04-1.15). A second model used the traditional risk factors plus antecedent BP (hazard ratio [HR] = 1.19; CI 95%: 1.10-1.24). In a third model that included traditional risk factors and both current and antecedent BP, the antecedent BP was significant (HR = 1.18; CI 95%: 1.08-1.23), but the current BP was not statistically significant (HR = 1.01; CI 95%: 0.97-1.09). Antecedent BP showed a significantly stronger effect on risk of CVD than current BP.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
