Circadian Variations of Blood Pressure in Acute Stroke Patients Treated at Adam Malik Hospital of Medan

Tri Makmur, F.A. Siregar and Nurul Huda

Several studies have shown that absence of blood pressure variation during sleep is associated with target organ damage including organ damaged sustained as a result of cerebrovascular accidents. In the management of stroke associated with hypertension, antihypertensive medications should be carefully administered because they may cause extensive damage to the brain. Twenty-four hour blood pressure monitoring is important. To investigate circadian variations in the blood pressure of stroke patients, a cross-sectional study was conducted. A sample of 30 patients who presented within 1-7 days of symptom onset and were aged 40 years or more was selected. The study participants’ blood pressures were measured by ambulatory monitoring. Personal and medical information were collected. Data analysis was performed using SPSS version 20.0. The Pearson Chi square test was used to analyze differences in the circadian patterns of blood pressure according to age, sex, type of stroke and both the onset and frequency of symptoms. An independent t-test was used to analyze differences in mean blood pressure. The results revealed that hypertension is major risk factor for stroke patients with a non-fluctuating pattern of blood pressure. Nondippers were more common than dippers. Nondippers were comprised 80, 90 and 83.3% of systolic, diastolic and mean arterial pressure groups. There were no significant differences in circadian patterns and mean blood pressure by age, sex, onset and frequency of symptoms and the type of stroke. These results indicate that the circadian rhythm of blood pressure is important in the management of hypertension.
