Q

Design a clinical exercise test for the aerobic assessment of heart failure

A

For a patient with heart failure, I would have them do a 6
minute walk. I would make sure to record their distance
travelled, HR and RPE’s this is so that we can tell just how hard
it is for the patient and ensure that they are not going to put
themselves at risk. Another thing that could be measured
would be their gas exchange to determine peak oxygen uptake.

Q

Why would a bench press be contraindicated in early phase cardiac
rehabilitation?

A

The valsalva maneuver must be avoided when patients are just
out of the hospital/starting cardiac rehab. If the patient was to
do a bench press they would be putting a lot of strain on their
chest. This is especially bad for those who have had open heart
surgery. This is because they have had their chest cracked open
and they should not be completing any upper body exercise for
at least the !rst 6 weeks.

Q

Describe the process of atherogenesis

A

Smooth muscle cells and !broblasts migrate from the media to
the intima. Monocytes also migrate into the intima after they
have adhered to the injured endothelium. The LDLc enters the
arterial wall and undergoes the process of oxidation. Forming
foam cells that may release their cholesterol into extracellular
space, giving rise to fatty streaks, the earliest visually detectable
lesion of atherosclerosis. Immune system cells, T lymphocytes,
are in the fatty streaks and they are part of the inflammatory
