NR 508 | NR 508 Week 3 Angiotensin-converting-enzyme (ACE) inhibitors are a central part of the treatment of heart failure because they have more than one action to address the pathological changes ... in this disorder. Which of the following pathological changes in heart failure is NOT addressed by ACE inhibitors? 1. Changes in the structure of the left ventricle so that it dilates, hypertrophies, and uses energy less efficiently. 2. Reduced formation of cross-bridges so that contractile force decreases. 3. Activation of the sympathetic nervous system that increases heart rate and preload. 4. Decreased renal blood flow that decreases oxygen supply to the kidneys. 3. Activation of the sympathetic nervous system that increases heart rate and preload. One of the three types of heart failure involves systolic dysfunction. Potential causes of this most common form of heart failure include: 1. Myocardial ischemia and injury secondary to myocardial infarction 2. Inadequate relaxation and loss of muscle fiber secondary to valvular dysfunction 3. Increased demands of the heart beyond its ability to adapt secondary to anemia 4. Slower filling rate and elevated systolic pressures secondary to uncontrolled hypertension 1. Myocardial ischemia and injury secondary to myocardial infarction [Show More]
