Why the study?
Is early systolic blood pressure response to exercise associated with left atrial volume index and pulse wave velocity?
Population
205 patients (137 men and 68 women; mean age 58 ± 11 years; range, 19 to 83 years)
Design
Cross-sectional
Key result
In women, increased left atrial volume index was significantly associated with early systolic blood pressure elevation during exercise (R2 = 0.192, p = 0.002), whereas pulse wave velocity showed no association.

Effect estimate: R2 = 0.192
p-value: p=0.002
Early systolic blood pressure elevation during exercise is associated with increased left atrial volume index in women, suggesting a sex-specific relationship between exercise hemodynamics and left atrial remodeling.
Park et al. (2013) conducted an observational in Chest pain or chest discomfort (n=205). Graded exercise test (BRUCE protocol) was evaluated on Association between early systolic blood pressure response to exercise (delta SBP1) and left atrial volume index (LAVI) in women (R2 = 0.192, p=0.002). In women, increased left atrial volume index was significantly associated with early systolic blood pressure elevation during exercise (R2 = 0.192, p = 0.002), whereas pulse wave velocity showed no association.
