EHMTI-0249. Headache attributed to hypertension in chronic migraine patients

In the MwHBP group 65% of patients presented a second type of headache corresponding to “headache attributed to hypertension” criteria compared to 33% in the HBPw/oM group. This type of headache in MwHBP group was unilateral (60% vs. 23.1%, p<0.05), pulsating (60% vs. 17.9%, p<0.05), in any part of the day (80% vs. 23.1%, p<0.05), with the combination of two or more associated symptoms (100% vs. 0%) compared with HBPw/oM group - predominantly on the morning, with isolated associated symptoms (30% - just photophobia vs. 0%, 40% - just phonophobia vs. 0%, 30% - just nausea vs. 0%, p<0.05). Conclusion In the chronic migraine patients with associated hypertension could be detected two types of headaches. The first one is migraine and the second - “headache attributed to hypertension”, which is more frequent than in the hypertension without migraine group (65% vs. 33%) and preserved the migrainous features. No conflict of interest.
