In which patient demographics should atypical ACS be considered?

• A. Patients over 65, females, minorities, and diabetics
• B. Young athletes
• C. Only males
• D. Pediatric patients

Answer: (A)

Atypical ACS is most likely to be seen in patients who may not have the classic chest pain. In older adults, women, people from minority groups, and those with diabetes, ischemic heart disease often presents with nonclassic symptoms such as shortness of breath, fatigue, nausea, epigastric or back/jaw discomfort, or confusion rather than the typical crushing chest pain. This is why the best choice includes older patients, females, minorities, and diabetics: these groups require a high index of suspicion and appropriate testing even when the presentation isn’t textbook.

Understanding why helps: aging and multiple health issues can blunt pain perception; hormonal and physiological differences in women can shift symptoms toward noncardiac-appearing signs; diabetes can cause autonomic neuropathy leading to silent or atypical ischemia; and minority populations may have different symptom patterns and access-related factors that influence presentation. Because of this, clinicians should evaluate suspected ACS with ECG and cardiac biomarkers in these groups even if the symptoms aren’t classic.

Young athletes and pediatric patients are less commonly presenting with ACS in the typical way, and insisting that only males have ACS ignores presentations in women and other groups.
