A 65-year-old man presented proteinuria in the nephrotic range that occurs in the setting of high renin hypertension. Proteinuria persisted after normalizing blood pressure by nifedipine. In contrast, treatment with an ACE-inhibitor (enalapril) resulted in the prompt resolution of the proteinuria. Interestingly, proteinuria relapsed after removing the ACE-inhibition. These observations suggest a causal relation between the overactivity of the renin-angiotensin system in this patient and his proteinuria.

In order to lower arterial blood pressure, antihypertensive drugs decrease cardiac output, total peripheral resistance or both. Diuretics, beta-blockers, and central adrenergic inhibitors decrease cardiac output. ACE inhibitors, angiotensin II antagonists, calcium antagonists, alpha-blockers, central adrenergic inhibitors, and after a delay also diuretics and beta-blockers decrease peripheral resistance. Diuretics are first line therapy for treating low renin hypertension. Beta blockers are used for treating high renin hypertension and patients suffering additional coronary artery disease. ACE inihibitors can be given for treating high renin hypertension particularly in conjunction with diabetes, heart failure or left ventricular hypertrophy. Combining ACE inhibitors with diuretics potentiates the antihypertensive effect. Angiotensin II antagonists exert fewer side effects and better renal protection than ACE inhibitors. The main indication for calcium antagonists is low renin hypertension, their advantages being strong blood pressure reduction as well as in preventing stroke. Central alpha2 receptor agonists and other vasodilators are chosen only in selected cases and mostly in combination with other antihypertensive drugs.

In the 1970s, pharmacological therapy interrupting the renin-angiotensin system was considered beneficial for patients with high-renin hypertension. This gave rise to the development of ACE inhibitors. Surprisingly, the ACE inhibitors proved to be effective not only in patients with high renin hypertension, but also in many patients with normal levels of plasma renin activity. At present ACE inhibitors have a significant position in a wide range of chronic illnesses such as atherosclerosis, hypertension, myocardial infarction, diabetic complications, stroke etc. They are combined safely with drugs like angiotensin receptor blockers, calcium channel blockers and thiazides with varying degree of benefits. Though they are safe drugs, patients need monitoring for renal insufficiency, hypotension, hyperkalemia etc. The safety of these drugs in paediatrics patients is not established. It is better to avoid these drugs during pregnancy.
