Final answer:
Older adults with comorbidities, athletes, and young adults are groups at high risk for cardiac emergencies with atypical symptoms.
Step-by-step explanation:
Groups at high risk for cardiac emergencies that may appear with atypical symptoms include:
- Older adults with comorbidities: The risk of cardiovascular diseases increases with age, and older adults with comorbidities such as diabetes or high blood pressure are at a higher risk.
- Athletes: Although athletes are generally more fit, intense physical activity can put strain on the heart and increase the risk of cardiac emergencies.
- Young adults: Although less common, young adults can still experience cardiac emergencies, and they may present with atypical symptoms that can be easily overlooked.
