Individualized versus standardized analysis of ambulatory blood pressure profile: relationship with left ventricular characteristics
Objective To determine whether the use of patients' individual awake/asleep patterns instead of fixed day/night intervals would influence the correlations between blood pressure values and left ventricular morpho-functional characteristics. We enrolled 167 never-treated hypertensives (clinic bl...

Zusammenfassung: | Objective To determine whether the use of patients' individual awake/asleep patterns instead of fixed day/night intervals would influence the correlations between blood pressure values and left ventricular morpho-functional characteristics.
We enrolled 167 never-treated hypertensives (clinic blood pressures >160 mmHg systolic or 90 mmHg diastolic, or both): 32 had 24h blood pressures 130 mmHg systolic or 80 mmHg diastolic, or both (hypertensives). Each patient underwent left ventricular echocardiographic examination and 24h ambulatory blood pressure monitoring, evaluated twice, using standard day/night intervals (daytime 0700-2200 h, night-time 2200-0700 h) and using the patient's individual awake/asleep pattern (an individualized scheme).
Daytime and night-time blood pressures in WCH and daytime and night-time diastolic blood pressures in hypertensives were not affected by choice of using individualized or standard intervals; daytime systolic blood pressure in hypertensives was significantly higher and night-time systolic blood pressure lower with individualized intervals. The non-dippers (nocturnal decrease in blood pressure |
