Abstract
The goal of antihypertensive treatment is to reduce overall CVD risk and thus its morbidity and mortality rates. In any given patient, the decision to begin treatment is governed by the risk of CVD, which is determined by the magnitude of the BP elevation and the presence or absence of target organ disease and/or additional CVD risk factors. Recent consensus committees, including JNC VI and the World Health Organization–International Society of Hypertension (WHO-ISH) Guidelines Subcommittee, have modified traditional treatment recommendations in several important ways3,35 : (1) Criteria for initiation of treatment now take into consideration total cardiovascular risk rather than BP alone, such that treatment is now recommended for persons whose BP is in the normal range but still bear a heavy burden of CVD risk factors or established CVD. (2) Systolic BP is recognized as an important target for treatment, particularly in older persons, because it is an even more important determinant of CVD risk than diastolic BP. (3) More aggressive BP goals are recommended for hypertensive patients with comorbid conditions such as diabetes mellitus or renal insufficiency. (4) The importance of tailoring the choice of antihypertensive drug treatment to the patient’s individual profile of concomitant CVD risk factors/comorbid conditions is emphasized. (5) The role of simultaneous reduction of multiple CVD risk factors in improving prognosis in hypertensive patients is stressed. (6) Home and ambulatory BP measurement has been recommended because of its value in guiding therapy and enhancing adherence to treatment. (7) Greater reliance on evidence-based medicine (ie, results of randomized controlled trials with CVD outcomes) in making treatment decisions has been endorsed. JNC VI has arrived at an empirical classification that stratifies hypertensive patients into risk groups for therapeutic decisions (Table 4⇓). Risk group A includes patients who do not have clinical CVD, target …
