A patient was presented to an emergency department soon after having chest pain. The ECG showed STEMI. The day after acute percutaneous coronary intervention, cardiac enzymes met the criteria for myocardial infarction, but the echocardiogram showed a normal left ventricular ejection fraction. Should the patient be treated with a β-blocker?
A researcher said that the use of β-blockers was prominent in an era when reperfusion therapy wasn’t introduced. However, now that reperfusion therapy is known to prevent or severely limit heart muscle damage in most patients with acute MI, the use of β-blocker after MI is no longer valid.
