None of the options is an absolute contraindication to the use of intravenous β-blockers in acute myocardial infarction. The benefits of intravenous β-blocker therapy early in acute infarction is well established, presumably due to both reduction in myocardial oxygen consumption afforded by the negative inotropic and chronotropic actions, and a direct antiarrhythmic effect. Often, this important treatment is withheld in patients with sinus bradycardia (D), diabetes (A), and well-controlled asthma (B); at most, these conditions should be considered relative contraindications, and β-blockers should be administered carefully to most infarcting patients with these concomitant conditions. The increased incidence of bradyarrhythmias in inferior infarcts does not justify withholding β-blockers ©, as these rhythm disturbances tend to be reversible and are easily treated with temporary pacing if symptomatic. Severe systolic heart failure (from massive myocardial damage, right ventricular infarction, or acute valvular regurgitation) and active wheezing from reactive airway disease remain absolute contraindications to β-blockade.
