Angiotensin-converting enzymes inhibitors (ACE inhibitors) should be started within 24 hours of an AMI to reduce the incidence of: a. myocardial stunning. b. hibernating myocardium. c. myocardial remodeling. d. tachycardia. ANS: C Myocardial remodeling is a process mediated by angiotensin II, aldosterone, catecholamine, adenosine, and inflammatory cytokines, which causes myocyte hypertrophy and loss of contractile function in the areas of the heart distant from the site of infarctions. ACE inhibitors reduce the incidence of remodeling. Incorrect: A: Myocardial stunning is a temporary loss of contractile function that persists for hours to days after perfusion has been restored. Myocardial remodeling is a process that causes myocyte hypertrophy and loss of contractile function in the areas of the heart distant from the site of infarctions. ACE inhibitors reduce the incidence of remodeling. B: Hibernating myocardium is tissue that is persistently ischemic and undergoes metabolic adaptation to prolong myocyte survival until perfusion can be restored. Myocardial remodeling is a process that causes myocyte hypertrophy and loss of contractile function in the areas of the heart distant from the site of infarctions. ACE inhibitors reduce the incidence of remodeling.

Complete occlusion of a coronary artery Fatty streak within the intima of a coronary artery Partial occlusion of a coronary artery with a thrombus Vasospasm of a coronary artery ANS: C In unstable angina, some blood continues to flow through the affected coronary artery; however, flow is diminished related to partial occlusion. The pain in unstable angina is more severe, may occur at rest, and requires more frequent nitrate therapy. Incorrect: A: Complete occlusion of a coronary artery results in AMI. B: A fatty streak leads to the presence of fibrotic plaque leading to complicated lesion formation, which may later cause stable angina, unstable angina, or an MI . It is not the primary physiological mechanism of unstable angina. D: Variant, or Prinzmetal’s, angina is caused by coronary artery spasms.

Electrophysiology study ANS: C Echocardiography is a noninvasive, acoustic imaging procedure and involves the use of ultrasound to visualize the cardiac structures and the motion and function of cardiac valves and chambers. Incorrect: A: The 12-lead electrocardiogram is useful in identification of rhythm disturbances and myocardial ischemia, injury, or infarct. B: Cardiac catheterization is used to confirm and evaluate the severity of lesions within the coronary arteries, to assess left ventricular function, and to measure pressures in the chambers of the heart, cardiac output, and blood gas content.
