Hypertension

Nephrology

Hypertension is one of the most common diseases afflicting humans throughout the world. Because of the associated morbidity and mortality and the cost to society, hypertension is an important public health challenge.

Hypertension

Pediatrics

Hypertension is a major cause of morbidity and mortality in the US and many other countries. The prevalence of hypertension in the adult US population, defined by a single measurement of 140/90 mm Hg or more obtained under nonstandardized conditions, is estimated to be 15-20%. This compares with a prevalence of 1.5-2.0% among children aged 4-15 years in whom hypertension was defined as a blood pressure persistently greater than the 95th percentile for age.

Hypertensive Emergencies

Emergency Medicine

Patients with hypertension in the ED can be classified into 3 categories based upon their symptoms and the organ systems that are affected at the time of presentation: hypertensive emergency, hypertensive urgency, and severe hypertension. Optimal control of hypertensive situations balances the benefits of immediate decreases in BP against the risk of significant decrease in end-organ perfusion.

Hypertensive Heart Disease

Cardiology

Uncontrolled and prolonged elevation of blood pressure (BP) can lead to a variety of changes in the myocardial structure, coronary vasculature, and conduction system of the heart. These changes can lead to development of left ventricular hypertrophy (LVH), coronary artery disease, various conduction system diseases, and systolic and diastolic dysfunction of the myocardium, which present clinically as angina or myocardial infarction, cardiac arrhythmias (especially atrial fibrillation), and congestive heart failure (CHF).

Nephrosclerosis

Nephrology

According to the US Renal Data System, hypertensive nephrosclerosis (HN) accounts for as many as 34% of patients reaching end-stage renal disease (ESRD) each year in the United States. According to this report, HN is the second most common cause of ESRD in white people (21%) and is the leading cause of ESRD in black people (34%).
