Use of ambulatory blood pressure monitoring in hypertensive patient to monitor blood pressure control

Aim: To use ambulatory blood pressure monitoring in hypertensive patient for better control of their blood pressure. Protocol: This was a single centre, observational study that included hypertensive patients who visited the out-patient department of tertiary care hospital Nepal. The study was carried out from June, 2021 to June, 2023. All the patients were assessed through ambulatory blood pressure monitoring machine for 24 hours. Total 259 patient were studied with ambulatory 24 hours blood pressure monitoring. Average age was 44.82±13.67 years. 30 to 50 age group was the maximum user of ABPM (41%) 20 patient in this study were ?65years of age. 58 % patients were males and 42% were female. All the patient undergoing ABPM were hypertensive. Mean of 24 hours systolic BP was 129.69 ± 12.86 mmHg and diastolic BP was 81.91±9.2 mmHg, awake systolic BP was 134.5 ± 12.5 mmHg and diastolic BP was 86.32±9.44 mmHg, asleep systolic BP was 121± 15.1 mmHg and diastolic BP was 74.46±10.38 mmHg. Only 28 (10.8%) patient of 259 had normal mean daytime blood pressure while 21 patient 8.1% had elevated BP and 210 patient 81.1% had hypertension as per AHA/ACC 2017 classification. Of total hypertensive 210 patient 84% had grade 2 hypertension and 16% had grade 1 hypertension requiring intensification of medication to control blood pressure in majority of the patient. Conclusion: Most of the patient treated with hypertension had inadequate control as seen on ambulatory blood pressure monitoring. ABPM should be utilized in every hypertensive patient to monitor the adequate control of BP.
