Ventricular aneurysms are generally but not always secondary to myocardial infactions which are generally but not always secondary to coronary artery disease.
The usual medication post MI or with CAD will usually include ALL the following
A) Antiplatelets agents (Aspirin, clopidogrel, newer agents…)
B) Beta-Blockers (BP reduction, Pulse reduction, arrhytmia reduction)
C) Cholesterol lowering agent (Statins)
D) ACEI, ARB or if ACE/ARB cannot be tolerated (or the patient is of african origin) an hydralazine/ISMN combination, with an aldosterone antagonist (if there is heart failure)
+/- fluid control with diuretics such as furosemide.
E) other medications/devices for more specific situation or severity of disease.
A pt with a ventricular aneurysm should probably be on both (if BP or renal function permit) a beta blocker and either an ACE or ARB as both help with BP control and heve synergetic effect to inhibit disadvantageous myocardial remodeling. Moreover, BB reduce the risk of malignant arrhytmia inherent to a ventricular aneurysm.
Considering that there is significant clinical evidence supporting the use of BB and ACE/ARBs in situations like this and that the current level of evidence supporting the use of hgh is marginal (no large double blind randomized trials with many thousands of patients) I would not encourage the replacement of a clearly demonstrated effective medication with something that is, while interesting, not currently demonstrated as effective in RCTS.
Hope that helps somewhat.
