Background
Most patient with stroke have hypertnesion and the stroke accidental rate is very closely connected with hypertension. So, the proper diagnosis and treatment of the hypertension play very important roles the treatment and the prognosis of stroke as well as on the prevention of recurrent stroke.
The goal of this study is to improve the treatment of hypertension in stroke-inpatients by investigating the 24-hours blood pressure using the ambulatory blood pressure monitoring.
Methods
52 inpatient with stroke were randomly selected in the 2nd internal medicine department, Kyunghee oriental hospital and devided into normotensive and hypertensive groups by the standard-whether he/she takes the blood pressure drugs. We set the machine (ambulatory blood pressure monitoring) to check the blood pressure (including systolic and diastolic blood pressure) and pulse rate every 30 minutes from 06:00 to 22:00 and every 1 hour from 22:00 to 06:00. And the frequency percentage of systolic blood pressure over 140mmHg and the diastolic blood pressure over 90mmHg makes the blood pressure load.
Results
The mean systolic blood pressure during 24 hours were 129¡¾10.3§®Hg at normotensive group and 140 14.9§®Hg at hypertensive group and the mean diasolic blood pressure were 79 7.0§®Hg at normotensive group and 83 8.2§®Hg at hypertensive group. The blood pressure loads were 30.0 22.0% (systolic) and 21.1 18.2(diastolic) at normotensive group. That were 51.2 30.3%(systolic) and 36.0 24.1%(diastolic) at hypertensive group.
The pattern of circardian blood pressure was lowest at the time from 00:00 to 06:00 and made the rapid increase temporalily to reach the turning point at 07:00. After that time it decreased a little bit and continued with no significant change and made the highest point at 19:00 and it decreased rapidly after 22:00. The patter of circardian pulse rate was similar to blood pressure pattern.
In systolic and diastolic blood pressure, there was no significant difference between ambulatory and casual blood pressure.
Conclusions
These results show that the diagnosis of hypertension with casual blood pressure is available as well as ambulatory blood pressure and that more intensive control of blood pressure is required in stroke-inpatients with hypertension. And the change of pulse rate can be another useful standard to diagnosis hypertension and to rule out the inappropiate things among the datas from ambulatory blood pressure monitoring.
