Answer: clients with low or no associated risk factors and Low troponins level after ECG is performed.
Step-by-step explanation:
Associated risk factors with STEMI include High troponins level after ECG is performed, Age(above 40 years in men, at any age in women, and generally above 75 years), Gender(predominantly women), Family history, history of premature coronary artery disease, diabetes mellitus, hypertension (systolic higher than 100mmHg), abdominal obesity, cocaine use, increased heart rate ( higher than 100 beats per minute).
Therefore clients presenting with little or none of these risk factors are least likely to have an St-segment myocardial infarction (STEMI).
