Relationships between blood pressure measurements and target organ damage: Data from the Korea women's chest pain registry

This study was performed to investigate the association between four BP measurements (systolic blood pressure [SBP], diastolic blood pressure [DBP], mean arterial pressure [MAP], and pulse pressure [PP]) and four TOD parameters (left ventricular mass index [LVMI], E/e', estimated glomerular filtration rate [eGFR], and obstructive coronary artery disease [CAD]). Data were obtained from a nation-wide registry, composed of 652 patients (471 women, 58.4 ± 10.5 years) with suspected CAD who underwent elective invasive coronary angiography (CAG). A total of 217 patients (33.2%) had obstructive CAD (≥50%). In multivariable analyses, E/e' was associated with SBP, MAP and PP, and CAD was associated with SBP and PP (P < 0.05 for each). All four BP measurements were not associated with LVMI and eGFR (P > 0.05 for each). In patients undergoing elective invasive CAG, SBP, and PP had stronger relationships with E/e' and CAD than DBP and MAP.
