 An increment of 20 mmHg of systolic blood pressure or approximately equivalent 10 mmHg diastolic blood pressure is associated with more than a two-fold increase in risk of fatal stroke, and with a two-fold increase in fatal ischemic heart diseases in individuals aged 40-69 years. The management and control of high blood pressure is therefore one of the most important components of primary and secondary strategies for prevention of cardiovascular mortality and morbidity. Current guidelines for the clinical management of hypertension in adults recommend to achieve and maintain blood pressure levels of 14090 mmHg. However, it is uncertain what proportion of individuals identified with high blood pressure in primary care actually reach blood pressure control, what factors are associated with attainment of control and to what extent blood pressure control attainment is associated with cardiovascular diseases in a contemporary population of individuals diagnosed with high blood pressure. This is important for clinicians and policy decision makers in order to design and implement effective strategies for patient management.
