Answer to Question 1

Correct Answer: 1
Troponin is primarily located in cardiac muscle and can indicate myocardial infarction or unstable angina. Troponin elevates at 24 hours after myocardial infarction. CK and CK-MB will elevate with myocardial damage but will take longer to rise and are not as specific as troponin. Cholesterol level is not helpful in diagnosis of myocardial damage.

Answer to Question 2

Correct Answer: 1, 2, 3
Diabetes and hyperlipidemia are both disease conditions that contribute to coronary heart disease (CHD). Positive family history in some cases is considered a non-modifiable risk factor for CHD. Premenopausal women are not considered at an increased risk for CHD. Hypotension is not associated with development of CHD.
