Do specific multi-trajectories of systolic and diastolic hypertension increase the risk of incident coronary heart disease in middle-aged and older adults?
Medium-increasing-decreasing and high-decreasing blood pressure trajectories are associated with a significantly increased risk of coronary heart disease, highlighting the importance of longitudinal blood pressure monitoring and early intervention.
Effect estimate: OR 2.23 (95% CI 1.34-3.70)

Objective: This study aimed to investigate multi-trajectories of systolic and diastolic hypertension and assess their association with the risk of coronary heart disease (CHD) in middle-aged and older Chinese adults. Methods: The study cohort comprised 4,102 individuals aged 40-75 years with records of at least four systolic blood pressure (SBP) and diastolic blood pressure (DBP). A group-based multi-trajectory model was adopted to identify multi-trajectories of systolic and diastolic hypertension, followed by a logistic model to assess the independent associations between these trajectories and CHD risk. The multinomial logistic model was used to evaluate the impact of baseline covariates on trajectory groups. Results: Six distinct trajectories for systolic and diastolic hypertension were identified which represent distinct stages of hypertension and were characterized as low-stable, low-increasing, medium-decreasing, medium-increasing-decreasing, isolated systolic hypertension phase, and high-decreasing. Compared with the low-stable group, the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were 2.23 (1.34-3.70) for the medium-increasing-decreasing group and 1.87 (1.12-3.11) for the high-decreasing group after adjustment for baseline covariates. Compared with the low-increasing group, the ORs and 95% CIs were 1.88 (1.06-3.31) for the medium-increasing-decreasing group. Age, gender, drinking, body mass index (BMI), triglyceride (TG), and fasting plasma glucose (FPG) were independent predictors for trajectory groups 4 and 6. Conclusion: Novel, clinically defined multi-trajectories of systolic and diastolic hypertension were identified. Middle-aged and older adults with medium-increasing-decreasing or high-decreasing blood pressure trajectories are potentially critical periods for the development of CHD. Preventing adverse changes in hypertension status and reducing the high risk of CHD is necessary for people in distinct trajectory groups.
Li et al. (Thu,) conducted a cohort in Hypertension and Coronary Heart Disease (n=4,102). Medium-increasing-decreasing blood pressure trajectory vs. Low-stable blood pressure trajectory was evaluated on Coronary heart disease (CHD) (OR 2.23, 95% CI 1.34-3.70, p=<0.01). A medium-increasing-decreasing blood pressure trajectory was associated with a significantly increased risk of coronary heart disease compared to a low-stable trajectory (OR 2.23).
