Re: Enalapril Question
Enalapril is another one of the ACE inhibitor drugs. It is
used to treat congestive heart failure and high blood pressure. It
is excreted primarily by the liver and secondarily by the kidneys.
A rare side effect may be reduction of blood flow to the kidneys to
such an extent that they may fail. However, this generally only
occurs when the kidneys are already stressed or weak or a diuretic
(lasix, hydrochlorothiazide or spironolactone) is being given
concurrently. Every medication has potential side effects, and for
a kitty with no previous renal disease enalapril seems to be a safe
choice. The vets and doctors know *way, way* more than I do, so the
benefits must be outweighed more than a possible rare side effect,
so they choose to prescribe that drug.
The second degree AV block is an incomplete block between the
SA node (main pacemaker node in atrium) and the ventricles. These
are joined by the AV (atrioventricular node, aka bundle, tract ...)
There are two types of second degree blocks, type I and II. In type
I, the time between the SA node firing and the ventricles responding
gets longer and longer until one of the SA nodes signals do not get
though and the beat is "dropped" and the ventricle do not fire or
contract. In type II, the time between the SA node firing and
ventricular response is always the same, but random beats are
dropped by the ventricle, the electrical impulse gets through only
some of the time. My suspicion (which could be completely wrong!)
is that your kitties heart is in AV block because of the enlargement
which is interfering with its electrical conduction.
I hope smokey does well on his new med!
