Relationship between pulmonary function and peripheral vascular function in older Chinese: Guangzhou biobank cohort...

Area of Science:

• Cardiology
• Pulmonology
• Gerontology

Background:

• Inconclusive findings exist regarding the link between pulmonary and peripheral vascular function.
• The Guangzhou Biobank Cohort Study-Cardiovascular Subcohort (GBCS-CVD) was utilized to investigate this relationship.

Purpose of the Study:

• To explore the association between pulmonary function and vascular stiffness in older Chinese adults.
• To determine if pulmonary function is related to arterial stiffness and peripheral arterial disease (PAD).

Main Methods:

• Pulmonary function was assessed using spirometry, measuring forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC).
• Vascular stiffness was evaluated using brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI).
• Regression analyses were performed to examine the associations, adjusting for potential confounders.

Main Results:

• A significant negative association was found between pulmonary function (FEV1 and FVC) and arterial stiffness (baPWV) after adjusting for confounders.
• Lower pulmonary function was associated with a higher risk of arterial stiffness.
• The association between pulmonary function and peripheral arterial disease (PAD) was weaker and not statistically significant.

Conclusions:

• Pulmonary function is inversely associated with arterial stiffness in older, relatively healthy Chinese adults.
• The relationship between pulmonary function and PAD is less pronounced than with arterial stiffness.
• Findings suggest pulmonary function may be an indicator of vascular health in older populations.
