Which group is at risk for silent myocardial infarction?

• A. Young athletes
• B. Women, diabetics, and the elderly
• C. Smokers
• D. People with high cholesterol

Answer: (B)

Silent myocardial infarction occurs when a heart attack happens without the classic chest pain, so clinicians must recognize groups that are more likely to have atypical or absent symptoms. Diabetics often have autonomic neuropathy that dulls chest pain, making MI harder to recognize. The elderly frequently experience blunted pain responses and may present with nonspecific symptoms like fatigue, shortness of breath, or weakness rather than chest pressure. Women are more prone to atypical presentations, such as back, jaw, or abdominal discomfort, nausea, or fatigue, rather than the stereotypic chest pain.

Together, these factors make women, diabetics, and the elderly particularly at risk for silent myocardial infarction, so clinicians maintain a high index of suspicion for MI in these groups when symptoms are nonspecific or atypical.
