A Descriptive Study of Impaired Circadian Rhythm of Blood Pressure in Women with Hypertensive Disorders of Pregnancy and its Foetomaternal Outcome
Dr. Aditi Agarwal | Dr. Megha Agrawal
Abstract: Introduction: According to the World Health Organization (WHO) hypertensive disorders are the cause of most of the maternal deaths (25.7%) and therefore considered the main complication for pregnant women. Physiologically blood pressure is higher during the day time (between 09AM to6 PM) and lower at night (10 pm to 3:00 am). During night both systolic and diastolic blood pressure readings drop by about 10-20%. Material and Methods: This was a Descriptive type of observational study. Morning mean diastolic pressure (M) (between 6 am to 10 am) and nocturnal mean diastolic pressure (N) (between 10 pm to 3 am) of minimum 2 days of admission was noted and ratio of M/N was calculated. Result: In this study we included 100 patients. Out of 100 patients 54 patients were of gestational hypertension, 30 patients were of mild preeclampsia and 16 patients were of severe preeclampsia. Mean age for group A was 24.29 years, for group B it was 24.5 years and for group C it was 23.81 years. Morning DBP for group A was 103.8 followed by 97 of group B and 94.3 for group C. The mean nocturnal DBP for group A was 98.2 followed by 105.9 for group B and 115 for group C. Conclusion: We concluded that blunting/ reversal of circadian rhythm of blood pressure indicates progress of disease to its more severe form.
