  More Museful Mnemonics
Hello everybody. I really do love mnemonics, so here's a new one for all of us studying for PCCN certification. What is the best, but most underprescribed, class of drugs for heart failure?? ACE inhibitors of course. According to Woods et al. in their Cardiac Nursing Textbook, "These agents are the only drugs used in the treatment of chronic HF that have been shown both to improve symptoms and prolong life." To this day, I cannot understand why my grandmother, the typical class III CHFer, has not been taking these drugs; she and others like her should take them like vitamins. Rather, these patients are simply prescribed more and more diuretics, with more and more renal impairment. So any way, if you can remember PACE for ACE inhibitor, then you've got a good start.

For the species of the ACE inhibitor family: PACE
For the pharmacology of the class: PACE
For the adverse reactions: PACE INH-ibitor
Ta for now,
Christopher.
 
Comments:
Here's a comment: in diabetics
ACE's are often contraindicated because of their potential to precipitate hyperkalemia. Other medicines to precipitate high K+ levels in diabetics are:
* NSAIDS
* ACE inhibitors
* Beta-blockers
* Potassium sparing diuretics
* Salt substitutes (these are usually potassium salts).

According to PEARLS review, diabetics already have decreased Cellular uptake of potassium, because of hypoinsulinism, and often have hyporeninemic hypoaldosteronism ( renal tubular acidosis). Since ACE inhibitors precipitate diuresis by decreasing aldosterone, they will increase K+ levels.
 
Oh, BTW, ACEs work because along with inhibiting Angiotensin II, they inhibit aldosterone, which exerts action on renal distal tubules, sweat glands, salivary glands and intestines to retain water, and excrete K+. So that if aldosterone is inhibited K+ levels will rise.

That should clinch this one.
