Subsequently, Mr M underwent cardiac catheterization, revealing a lesion of the proximal left anterior descending coronary artery, which was then treated with a stent across the lesion. In addition, a post–myocardial infarction echocardiogram revealed congestive heart failure with a left ventricular ejection fraction of 25%.

At the time of the conference, 7 years after his presentation with his myocardial infarction, he had not experienced recurrent chest pain, shortness of breath, or palpitations, and his ejection fraction had remained stable; he did have a significantly lower tolerance for exercise. Because he has been relatively asymptomatic for so long, Mr M . . . [Full Text of this Article]
