What is the definition of hypertension in an adult?
Persistent blood pressure of 140/90 mmHg or above (severe hypertension is seen when pressures are >180/120 mmHg)
Which racial group(s) has(ve) the greatest risk of developing hypertension: blacks, whites, or Asians?
Blacks, then whites, then Asians
Secondary hypertension is most commonly secondary to disease in which organ(s)?
The kidneys (e.g., fibromuscular dysplasia, usually in younger women), the adrenal glands (e.g., primary hyperaldosteronism)
What are some risk factors for hypertension?
Increased age, obesity, diabetes, excess salt or alcohol intake, family history, physical inactivity
A patient has a blood pressure of 150/105 mmHg. Regardless of age, sex, and history, what is the most likely cause of the hypertension?
Due to increased cardiac output or total peripheral resistance (this is essential [1°] hypertension, causing 90% of cases of hypertension)
Name some cardiac conditions that individuals with hypertension are predisposed to.
Coronary artery disease, left ventricular hypertrophy, heart failure, stroke, aortic dissection/aneurysm, atrial fibrillation
Name some noncardiac conditions to which individuals with hypertension are predisposed.
Chronic kidney disease (hypertensive nephropathy), retinopathy
What is the difference between hypertensive urgency and hypertensive emergency in the context of severe hypertension (≥ 180/120 mmHg)?
Hypertensive urgency = acute end-organ damage is absent, hypertensive emergency = acute end-organ damage is present
Give some examples of acute end-organ damage seen in hypertensive emergencies.
Encephalopathy, stroke, HF, papilledema, retinal hemorrhages/exudates, aortic dissection, nephropathy, eclampsia, hemolytic anemia
