Use of ACE inhibition is currently recommended for all patients with evidence of myocardial dysfunction after heart attack. The use of beta blockers has been controversial because the medications decrease heart function. This can be problematic in patients already suffering from compromised heart function. However, new research has shown that beta blockers administered in low doses help to remodel the heart, restoring it to its normal geometry. This restoration allows for a more efficient ejection of blood.
Beta blockers can also help prevent death due to arrythmias.
Beta blockers and ACE inhibitors seem to be a winning combination for patients with heart failure. However, when treating patients with beta blockers, physicians must carefully monitor patients for signs of worsening heart failure. This is especially important early in treatment. Since it can often take months to notice improvement, patients must be encouraged to continue treatment while awaiting the beneficial effects of beta blockers. It also helps prevent symptoms from developing.
