Uyku Esnasındaki Apne ve Hipopne Ataklarının Kan Basıncına Akut Etkisi

Abstract

Objective: The present study aimed to investigate whether or not apneic and hypopneic attacks can cause acute blood pressure changes. Material and Methods: 82 patients with symptoms of obstructive sleep apnea were included in the study. A full overnight polysomnography was performed in the sleep laboratory. At the same time, 24-hour ambulatory blood pressure was monitored in all patients. Total apnea and hypopnea attacks between 23.00 and 07.00 hours were counted for each hour. All blood pressure levels were recorded and then compared for each sleep hour. Assessment was made as to whether or not immediate changes in apnea and hypopnea attacks affected the blood pressure. Results: The mean systolic blood pressure was 128.90±3.293 of the patients. The mean diastolic blood pressure was 77.29±0.98 mmHg. The mean heart rate was 72.68±0.77. The mean apnea hypopnea index (AHI) was 31.4±3.78. Systolic blood pressure, diastolic blood pressure, heart rate and AHI were recorded each hour independently and the mean values during the hours of sleep were compared statistically. The hourly changes of mean AHI (increase or decrease) did not correlate with the hourly changes of mean systolic blood pressure, mean diastolic blood pressure or mean heart rates (p=0.012). Conclusion: No acute changes between AHI and blood pressure were observed during the study.
