Probability of Having High Blood Pressure

Hypertension (high blood pressure) affects approximately 47% of American adults (about 116 million people), making it one of the most prevalent chronic conditions in the country. Under current guidelines (130/80 mmHg threshold), nearly half of all adults qualify as hypertensive. Only about 24% of those with hypertension have it adequately controlled.

Hypertension is called the "silent killer" because it typically has no symptoms until it causes serious damage. It is the leading modifiable risk factor for cardiovascular disease, stroke, kidney disease, and vascular dementia. Uncontrolled hypertension accounts for about 670,000 deaths in the US each year and is a primary or contributing cause of nearly half of all cardiovascular deaths.

Risk factors include age, family history, obesity, excessive sodium intake, insufficient potassium intake, physical inactivity, excessive alcohol consumption, smoking, and chronic stress. Black Americans have among the highest rates of hypertension in the world (about 56%). Treatment includes lifestyle modifications (DASH diet, exercise, weight loss, sodium restriction, stress management) and medications (ACE inhibitors, ARBs, calcium channel blockers, diuretics). Most patients require 2-3 medications to reach blood pressure goals.
