Heart Failure Tutorial

The following tutorial assumes the student is already knowledgeable of the content associated with the cardiac function tutorial. The student is encouraged to go not only to the initial link associated with each tutorial question but also to use embedded hyperlinks to expand upon the physiological concepts associated with the question.

Quiz Questions Linked to Tutorial

At the end of the tutorial, there is a link to an external website (testmoz.com) that has multiple choice and true/false questions that are associated with the tutorial. When the quiz results are given to the user after taking the quiz, links are provided back to specific cvphysiology.com pages to assist learning. Users will need to register (free) on the testmoz.com site to access the quiz questions for the tutorial. No personal information is available to cvphysiology.com other than the user provided login name and analysis of user performance on the quiz questions. This feedback will improve cvphysiology.com content and quiz questions.

Tutorial

1. What is heart failure?
2. List several conditions that can cause heart failure.
3. What is systolic dysfunction and how does this condition alter ventricular stroke volume, end-systolic and end-diastolic volumes, end-diastolic pressure, and ejection fraction?
4. How does the Frank-Starling mechanism compensate for reduced inotropy?
5. What changes in signal transduction mechanisms might cause systolic dysfunction?
6. What alterations in excitation-contraction coupling mechanisms might cause systolic dysfunction?
7. What is diastolic dysfunction and how does this condition affect ventricular stroke volume, ventricular end-diastolic volume and pressure, and ejection fraction?
8. How does ventricular hypertrophy affect diastolic function?
9. What role might altered sarcoplasmic reticulum function play in diastolic dysfunction?
10. How does combined systolic and diastolic dysfunction alter stroke volume, end-systolic and end-diastolic volumes, end-diastolic pressure, and ejection fraction?
11. What humoral and autonomic changes occur in heart failure and how do these changes help to compensate for impaired cardiac function?
12. How does activation of the renin-angiotensin-aldosterone system serve as a compensatory mechanism in heart failure?
13. How do natriuretic peptides counter-regulate the renin-angiotensin-system?
14. By what mechanism does heart failure cause pulmonary and systemic edema?
