Cardiovascular risk stratification chart with recommended follow-up frequency for each category. A reconstruction of Figure 1 from the 2007 Guidelines for Management of Arterial Hypertension , with inserted recommendations regarding the number of follow-up visits per year in each risk category. Low, moderate, high and very high risk refer to the 10-year risk of a CV fatal or non-fatal event. The term 'added' indicates in all categories that risk is greater than average. The risk factors referred to in the left column are: age, smoking, dyslipidaemia, elevated fasting plasma glucose, abnormal glucose tolerance test, abdominal obesity, a family history of premature CVD and 'high pulse pressure in the elderly'. Abbreviations: SBP: systolic blood pressure; DBP: diastolic blood pressure; HT: hypertension. OD: subclinical organ damage; MS: metabolic syndrome.
