The management and treatment of hypertension.
High blood pressure (HBP) is one of the most prevalent conditions seen today by clinicians, affecting an estimated 73 million--or 1 in 3--adult Americans, only one third of whom have achieved control of their hypertension (HBP). Central to the management of this pervasive medical condition are the issues of accurate diagnosis and maintaining control through appropriate treatment. Accurate diagnosis depends primarily on reliable measurement. Over the years, it has become increasingly recognized that blood pressure (BP) measurement occurring in clinical settings produces far less accurate and reliable readings than do other methods, notably 24-hour ambulatory BP monitoring and home BP measurement. Beyond technique, there are additional challenges to obtaining accurate readings, including emotional factors that produce either falsely elevated or lowered results, having the potential to mislead the clinician. The need to overcome obstacles to proper diagnosis and determine effective treatments has reached heightened urgency, especially for patients with compelling comorbidities such as diabetes, renal disease, congestive heart failure, and other cardiovascular diseases. The continuing evolution of the management of HBP is reflected in updated guidelines from the American Heart Association and evidence-based information stemming from recent studies and randomized clinical trials. The appropriate selection of antihypertensive agents, at the proper doses, is a complex issue requiring greater understanding of our pharmacologic options. The contributions of some of the more recent and salient studies and trials are mentioned here, although there is no attempt in this brief review to match drug classes with compelling indications. The trials discussed involve such pharmacologic treatments as diuretic therapy, alpha-blockers, conventional beta-blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin receptor blockers. Trial outcomes shed light on the relative benefits and drawbacks of these agents, often within the context of various patient characteristics such as age, comorbidities, and risk status. Successful management of HBP is a multi-faceted and ongoing endeavor, in which developing knowledge constantly tempered by new questions moves us toward the goal of improving the lives of our patients.
