Increased arterial stiffness is a known predictor of cardiovascular diseases in different populations, including healthy subjects and patients with hypertension, diabetes, or renal disease. A new study examining arterial stiffness in a large population determined that both restrictive spirometry pattern and reduced forced vital capacity (FVC) were associated with a higher risk of arterial stiffness not only in men but also in women. The investigators found that arterial stiffness increased fourfold when FVC decreased.
