doctor, why has my blood pressure gone bad?

I saw a lady in the clinic who asked me this question - she has diabetes and ischaemic heart disease . Her blood pressure has been on average 145/ 85 -90 on perindoril 8mg, amlodipine 10 mg and a small dose of thiazide. Suddenly on home monitoring her BP readings are up to 210 / 120 . Her machine has been tested. she is concordant with her medicines and nothing else has happened in terms of symptoms / medicine changes. Any thoughts? sadian
