Hypertension due to stenosis of the renal artery is classified as which type of hypertension?

• A. Essential hypertension benign
• B. Essential hypertension malignant
• C. Hypertensive renal disease
• D. Secondary hypertension

Answer: (D)

Hypertension caused by renal artery stenosis is classified as secondary hypertension. This classification arises because secondary hypertension is defined as high blood pressure that is a result of an identifiable underlying condition, such as renal artery stenosis. In this case, the narrowing of the renal artery leads to reduced blood flow to the kidneys, which can trigger the renin-angiotensin-aldosterone system (RAAS), ultimately causing an increase in blood pressure. Unlike essential hypertension, which has no identifiable cause and is considered primary hypertension, secondary hypertension can often be treated or resolved by addressing the underlying issue. Conditions that can lead to secondary hypertension include hormonal disorders, kidney disease, and certain medications. Therefore, recognizing the cause such as renal artery stenosis is crucial as it informs the treatment strategy and helps manage the condition effectively.
