Abstract:
A 61-year-old woman with chronic asthma sustained an episode of dyspnea and chest heaviness and was brought to the emergency department. Her examination revealed tachypnea, tachycardia, hypotension, and diffuse prolonged respiratory wheezing. Arterial blood gas analysis showed severe hypoxemia and hypercapnia. A 12-lead electrocardiogram showed marked, downsloping ST-segment depression, with deep, negative T waves in leads I, II, III, and aVF and precordial leads V3-V6. After 15 minutes of therapy with oxygen, beta-agonists, and corticosteroids, the electrocardiographic abnormalities subsided and 2 hours later they had disappeared. Subsequent coronary angiography and ventriculography revealed normal coronary arteries and good left ventricular ejection fraction. It is concluded that an acute asthmatic paroxysm may produce transient myocardial ischemia even with angiographically documented normal coronary arteries.
