Specifically, he says that he can barely walk up the stairs to his apartment before he feels winded. In addition, he has been waking up at night gasping for breath and has only been able to sleep propped up on 2 more pillows than usual. Physical exam reveals jugular venous distention as well as pitting lower extremity edema. Which of the following abnormal sounds will most likely be heard in this patient?? A: Extra heart sound in early diastole, B: Extra heart sound in late diastole, C: Fixed splitting, D: Opening snap, E: Parasternal holosystolic murmur,  <response>: This is a clinical vignette describing a patient with symptoms and signs consistent with heart failure, including shortness of breath, orthopnea, jugular venous distention, and lower extremity edema. The question asks which heart sound would most likely be heard in this patient.The choices describe different abnormal heart sounds. An opening snap suggests mitral stenosis. A holosystolic murmur suggests mitral regurgitation. Fixed splitting of S2 suggests a conduction abnormality like left bundle branch block. An extra heart sound in early diastole S3 suggests heart failure. An extra heart sound in late diastole S4 also suggests heart failure.Given this patients clear signs and symptoms of heart failure, the extra heart sound most likely to be heard is S3, an extra sound in early diastole caused by rapid filling of a stiff, noncompliant left ventricle.A: Extra heart sound in early diastole
