Overview

There are many classes of medications for treating hypertension, together called antihypertensives, which by varying means act by lowering blood pressure. Evidence suggests that reduction of the blood pressure by 5-6 mmHg can decrease the risk of stroke by 40%, of coronary heart disease by 15-20%, and reduces the likelihood of dementia, heart failure, and mortality from vascular disease.

Medical Therapy

Goals of Therapy

In addition to alleviating symptoms of hypertension, such as headache and blurry vision, the ultimate long term goals of the management of hypertension are to reduce cardiovascular risk, prevent cardiovascular events, and reverse or ameliorate target organ damage. According to “Blood Pressure Lowering Treatment Trialists’ Collaboration” in 2000, lowering blood pressure decreases the incidence of stroke by an average of 30%, MI by an average of 20%, major cardiovascular events by an average of 21%, and heart failure by an average of more than 50%.[1]

JNC 7 has established the goal blood pressure to be < 140/90 mmHg[2], with major focus on reduction of systolic blood pressure due to its role in the consequential reduction of diastolic blood pressure. In special populations such as those with diabetes mellitus or renal disease, the blood pressure goal is < 130/80 mmHg.[3][4]

Approach to Medical Therapy

A lot of debate exists on the optimal approach to the medical management of hypertension. With the multitude of classes and agents that can be used, several questions arise about the single best agent, the optimal combination of agents, and the best step-wise approach to medical management. Although JNC7 tried to address these issues, almost a decade has passed since the release of their recommendations, with a myriad of studies and trials presenting newer compelling evidence to update the current recommendations. The 2013 ESH/ESC guidelines for the management of hypertension have dwelled into these issues and have outlined the rationale behind adopting a new approach. Below are the algorithms for the approach to the medical therapy of hypertension presented by JNC7 in 2004 and ESH/ESC in 2013.
