Hypertension is a common clinical condition, categorized into primary (essential) hypertension and secondary hypertension. The majority of patients have primary hypertension, whose exact cause remains unclear. Current understanding suggests it is associated with multiple factors including genetic predisposition, dietary habits, psychological factors, smoking, and obesity. Clinical management requires lifestyle modifications and medication, necessitating lifelong treatment as there is currently no cure. A small percentage of hypertension cases, approximately 5%, are caused by secondary factors, meaning they result from specific underlying conditions that elevate blood pressure. Diseases leading to secondary hypertension include primary aldosteronism, pheochromocytoma, renal vascular hypertension, and renin-secreting tumors, among others. These conditions can often be cured or significantly improved through surgical intervention. Therefore, patients with secondary hypertension have the potential to be cured.
