In many individuals, blood pressure varies between clinic visits conducted days, weeks, or months apart. This visit-to-visit variability (VVV) of blood pressure has been recently related with an increased risk of coronary heart disease, stroke, and mortality, independently of mean blood pressure. As for other chronical diseases, patients' adherence to hypertensive therapies remains low and partial adherence to antihypertensive treatment may constitute a source of VVV, as suggested by recent studies. This data should lead to a new clinical approach for hypertension care, based on patients' real adherence to treatment. Therapeutic strategies should include patients' adherence. In this context, the role of community pharmacists for patients' follow-up of hypertension should be reinforced, as they represent efficient and easily accessible health professionals.
