Abstract
BACKGROUND
The progression of Central Blood Pressure (CBP) values and central hemodynamic parameters and its relationship with cardiovascular risk factors is quite unknown. We sought to investigate this association in a Spanish adult population without cardiovascular diseases.
METHODS
Prospective observational research with a five-year follow-up. Randomly sampled 501 individuals (mean age 56±14 years, 50.3% women). After five years, 480 individuals had a follow-up. Measurements taken using the SphygmoCor® (AtCor Medical Pty Ltd., Head Office,West Ryde, Australia), following all the recommendations established in the "International task force"1, giving an estimate of central blood pressure relative to measured brachial blood pressure (type 1 device).
RESULTS
Progressions during follow-up: central systolic blood pressure (cSBP): 4.16±13.71 mmHg; central diastolic blood pressure (cDBP): 2.45±11.37 mmHg; central pulse pressure (cPP): 1.72±12.43 mmHg; pulse pressure amplification (PPA): 2.85±12.20 mmHg; ejection duration (ED): 7.00±47.87 ms; subendocardial viability ratio (SEVR): -8.04±36.24%. In multiple regression analysis: cSBP positively associated with: BMI (β=0.476); waist size (β=0.159); number of cigarettes per day (β=0.192). Inversely associated with peripheral systolic blood pressure (β=-0.282). cDBP increase positively associated with number of cigarettes per day (β=0.174). Inversely associated with peripheral diastolic blood pressure (β=-0.292). cPP increase positively associated with BMI (β=0.330). Inversely associated with peripheral pulse pressure (β=-0.262). PPA increase positively associated with: BMI (β=0.276); number of cigarettes per day (β=0.281). ED progress inversely associated with basal plasma glucose (β=-0.286).
CONCLUSIONS
All measures increased except for SEVR. Progressions in CBP and PPA were positively associated with anthropometric parameters and number of cigarettes and CBP inversely associated with peripheral blood pressure, although this association was different according to sex.
