Final answer:
Aspirin is recommended for adults at increased risk of CAD. A 12-lead ECG is a diagnostic tool that provides information about the heart's electrical activity.
Step-by-step explanation:
Aspirin and the 12-Lead ECG
Aspirin is recommended for adults at increased risk of coronary artery disease (CAD), such as postmenopausal women and individuals with risk factors like hypertension or diabetes. It reduces the risk of myocardial infarction but not overall death. However, it should only be taken if not contraindicated. On the other hand, a 12-lead ECG is a diagnostic tool that involves placing six electrodes on the chest and four on the limbs. It provides valuable information about the electrical activity of the heart and can help identify heart conditions, including CAD.
