Proton Pump Inhibitor Use and Incident Hypertension in Menopausal Women

Area of Science:

• Cardiovascular Health
• Pharmacology
• Epidemiology

Background:

• Proton pump inhibitors (PPIs) may impact blood pressure regulation by affecting nitric oxide production.
• The association between PPI use and the development of new-onset hypertension is not well understood.

Purpose of the Study:

• To investigate the relationship between proton pump inhibitor use and incident hypertension in postmenopausal women.
• To examine the association between the duration of PPI use and the risk of developing hypertension.

Main Methods:

• A cohort of 64,720 women from the Women's Health Initiative Observational Study were analyzed.
• Incident hypertension was assessed via self-report, with Cox proportional hazard models used to estimate risks.
• The impact of PPI use on blood pressure changes over three years was evaluated using linear regression.

Main Results:

• Proton pump inhibitor use was linked to a 17% increased risk of developing hypertension.
• A significant trend of incrementally higher hypertension risk was observed with longer durations of PPI use (trend P<0.001).
• New users of PPIs showed a significant increase in mean systolic blood pressure over three years compared to non-users.

Conclusions:

• Proton pump inhibitor use is associated with an elevated risk of diagnosed hypertension in menopausal women.
• The risk of hypertension demonstrated a significant trend correlating with the duration of PPI use.
• Further research is warranted to confirm these findings and elucidate the underlying mechanisms.
