Question

In a famous episode of the office from Season 5, Michael Scott's employee, Stanley, has a heart attack. Afterwards, Michael discusses, 'We found ourselves on the less-prepared side of things when Stanley's heart went berserk. And I knew exactly what to do, but in a much more real sense, I had no idea what to do (#mylife).' Stanley's heart attack would...

1) Show a decreased EDV and a corresponding decreased SV, increasing EF
2) Show a decreased EDV and a corresponding decreased SV, preserving EF
3) Show a decreased SV at a given EDV, lowering EF
4) Show a decreased SV at a given EDV, increasing EF

Answer 1

The correct scenario after Stanley's heart attack from 'The Office' would show a decreased SV at a given EDV, which results in a lower EF.

Step-by-step explanation:

The question revolves around the effects of a cardiac event on end-diastolic volume (EDV), stroke volume (SV), and ejection fraction (EF). With a heart attack such as Stanley's, we typically expect a decreased contractility due to damage to the myocardium, which leads to a decrease in SV at a given EDV. EDV may remain the same or even increase due to impaired ventricular emptying. This combination results in a lowered EF, because EF represents the percentage of the blood that is pumped out of the heart with each beat. Hence, the correct answer to the scenario described is that Stanley's heart attack would Show a decreased SV at a given EDV, lowering EF (option 3).
