SHIFT WORK IN NURSES AND 7-DAY/24H AMBULATORY BLOOD PRESSURE MONITORING

Abstract

Objective: The aim of the study is to evaluate seven day/24 h ambulatory blood pressure monitoring (ABPM) during shift work in nurses and compared then with 170 healthy subjects from our database of 7 day/24 h ABPM. Design and method: 297 healthy subjects and ten shift workers in hospital were monitored during shift work. The seven day working process was composed from the day with day work shift, night work shift systolic and diastolic blood pressure and weekly mean blood pressure values from the seven-day/24-h ambulatory blood pressure monitoring T 2431 (A and D, Japan). Results: In healthy subjects with aerobic training, seven days of systolic blood pressure was 115 ± 1.1 mmHg, diastolic 69 ± 1.4 mmHg, in days with exercise (0–24 h) systolic blood pressure was 115 ± 2.8 mmHg, diastolic 69 ± 1, 7 mmHg, in days without exercise (25–48 h) systolic blood pressure was 116 ± 3.4 mmHg, diastolic 69 ± 2.2 mmHg. In healthy subjects with combined training seven days of systolic blood pressure blood pressure was 113 ± 1.8 mmHg, diastolic 68 ± 1.4 mmHg, days with exercise (0–24 h) systolic blood pressure were 112 ± 1.9 mmHg, diastolic 69 ± 1, 5 mmHg, in days without exercise (25–48 h) systolic blood pressure was 113 ± 1.8 mmHg, diastolic 68 ± 1.4 mmHg. In patients with myocardial infarction, seventy-day mean systolic blood pressure was 122 ± 4 mmHg, diastolic 74 ± 3 mmHg, in days with exercise (0–24 h) systolic blood pressure was 121 ± 3 mmHg, diastolic 74 ± 2 mmHg, in days without exercise systolic blood pressure 121 ± 3 mmHg, diastolic 73 ± 3 mmHg. Conclusions: Our results showed that 1 hour of aerobic training, combined training did not change the 24-hour mean blood systolic and diastolic blood pressure profile assessed from a seven-day ambulatory blood pressure monitoring (7 days / 24 hours) in healthy subject and in patients, if the timing of exercise is during the day hours (6:00–22:00).
