He is a long-distant runner and last week, he couldn't complete his training session due to fatigue. he recently had a self-limiting upper respiratory illness. He does not use tobacco, alcohol, or illicit drugs and has not traveled recently. Temperature is 37.2 C (99 F), blood pressure is 110/62 mm Hg, pulse is 80/min, and respirations are 20/min. Physical examination reveals lung crackles. Echocardiography shows no valvular abnormalities and the following parameters: Based on the observed findings, which of the following is most accurate about this patient?

Eductional Objective: Stroke volume is the volume of blood pumped by the left ventricle in a single heartbeat. Defined as end-diastolic volume (EDV) minus end-systolic volume (ESV). Ejection fraction is the percentage of blood pumped by the left ventricle during each contraction (i.e., stroke volume divided by end diastolic volume). Cardiac output, the volume of blood ejected into the aorta per unit time, is estimated by multiplying stroke volume by heart rate.
