How important is cardiac remodeling in the elderly? |
The elderly are particularly
vulnerable to the consequences
of cardiac remodeling as, in this
population, the incidence of
myocardial infarction is higher
and remodeling precipitates overt
heart failure more rapidly than in
younger patients. Furthermore,
thrombolytic therapy is less effective
and has more contraindications in
this age-group. Although no studies
have specifically addressed remodeling
in the elderly, the findings of
large trials suggest that thrombolytic
therapy and early initiation of
angiotensin-converting enzyme
(ACE) inhibition, especially following
extensive anterior myocardial
infarction, may prevent or reduce
the dilation of the left ventricle.
Recent reports show that the
ß-blockers improve survival and
functional capacity in patients
with severe left ventricular dysfunction,
but whether this beneficial
effect, which is additive to that of
the ACE inhibitors, is correlated
with regression of remodeling
remains to be determined...
