The objective was to examine the association between high blood pressure (BP) and chronic daily headache using 24-h ambulatory blood pressure monitorization (24-h ABPM). This was a cross sectional study in an out-patient clinic. Women were selected among patients referred for first evaluation, 62 with chronic daily headache and 57 without chronic daily headache. The main outcome measures were mean office systolic and diastolic blood pressure (BP), mean systolic and diastolic daytime and night-time BP and BP load, and mean systolic and diastolic nocturnal fall. Office systolic BP was 138.2 mmHg for women with chronic daily headache and 141.7 mmHg for women without headache (P = 0.36). Office diastolic BP was 88.9 mmHg for women with headache and 92.7 mmHg for women without headache (P = 0.17). Mean daytime and mean night-time systolic BP was, respectively, 122.2 mmHg and 108.8 mmHg for women with headache and 122.9 mmHg and 109.5 for women without headache (P = 0.82 and P = 0.80, respectively). Mean daytime and mean night-time diastolic BP was, respectively, 78.6 mmHg and 65.4 mmHg for women with headache and 79.9 mmHg and 67.1 mmHg for the women without headache (P = 0.80 and P = 0.45, respectively). There was no difference between the two groups regarding systolic and diastolic BP load and nocturnal systolic and diastolic fall. No significant difference in BP values was observed in women with chronic daily headache compared with women without headache using 24-h ABPM. b
