To the Editor: In a study analyzing data from the National Registry of Myocardial Infarction, Dr Canto and colleagues1 emphasized sex differences in the presentation of MI without chest pain. However, 64.5% presented with chest pain (69.3% of men and 58.0% of women). In both sexes, chest pain/discomfort remains the most common presentation.2
