ABSTRACT
OBJECTIVE: Pattern with essential hypertension generally shows the same circadian pattern as the normothensive person with a night-time reduction or "DIP" in blood pressure in sleep. The definition of "Dipper" and "Non-dipper" are assigned according to arbitrary criteria e.g. a night time average blood pressure which is at least 10% less than the average daytime blood pressure. Prospective evidence that the absence of an overnight dip is a strong adverse prognostic indicator for target organ damage .Thus we investigate circardian rhythm of blood pressure, related target organ damage, its frequency & drug in hypertensive subjects. Method : 24hr ambulatory blood pressure monitoring, history taking, physical examination, fundoscopy, ECG, chest X ray, dipstick urinanlysis, serum creatinine level are performed in essential hypertensive subjects. Exclusion criteria are duration of hypertension over 5 years, DM, renovascular hypertension & heart failure. RESULTS: Total 42 patients performed study.17 subjects classify dipper group,25 subjects classify non-dipper group. Between dipper & non-dipper group shows no significantly difference at stroke history, C/T ratio over 0.5 in chest X-ray, left ventrcular hypertrophy in ECG,ST-T change in ECG, proteinuria & serum creatinine level. Non-dipper group shows significantly difference to dipper group in frequency of hypertensive retinopathy and number of combined drug used subjects. CONCLUSION: Number of hypertensive retinopathy is significantly frequency in non-dipper group. Hypertensive retinopathy is atherosclerotic complication, thus we predict other target organ damage, therefore non-dipper type circardian rhythm of blood pressure is adverse prognostic factor for target organ damage of hypertensive subjects.
