Objective:
To describe the circadian blood pressure (BP) pattern in stable COPD patients.
Methods:
We included stable COPD patients from Internal Medicine Departments. Office BP and ambulatory BP monitoring were performed. Patients were classified as BP reducers (dipper or extreme dipper) or non-reducers (non-dipper or riser).
Results:
We included 43 patients (5 women, mean age 69.5 ± 9.5 years). Among them, 11 had sustained normotension, 13 sustained hypertension, 2 white coat hypertension, and 17 masked hypertension. Arterial stiffness was observed in 12 (27.9%) patients. Overall, 26 (60.5%) exhibited a non-reducer BP profile. Non-reducers had a higher frequency of previous major cardiovascular events (50% vs. 11.8%, p = 0.020) and long-acting muscarinic antagonist use (84.6% vs. 47.1%, p = 0.009).
Conclusions:
Hypertension is often masked in COPD patients, who frequently display an altered circadian BP pattern. Longitudinal studies with larger samples are needed to evaluate the impact of these patterns on COPD progression.

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.
