Flashcards in 25. Cardiac Rehab Deck (11):
1

What are the beneficial outcomes of exercise during cardiac rehab?

-Slowed, stopped, or revered atherosclerosis
-Clinical events drop b/c clotting less frequently
-Patient can work harder, longer, w/ fewer symptoms

2

What % of patients surviving an MI get referred to a cardiac rehab program?

3

Explain the role of lipid management in cardiac rehab.

-Reduce lipid delivery (via diet) --> plaque doesn't grow anymore
-Increase lipid removal (exercise, meds) --> plaque may even shrink

4

What are the general "heart healthy" diet recommendations? What should a patient reduce? Increase?

REDUCE:
-saturated and trans fats
-dietary cholesterol
-sugars, calories, and salts IFF in excess
INCREASE:
-fruits and veggies
-fiber
-foods w/ antioxidants
-fish oils

5

What do "statin" meds do?

-Reduce LDL and triglycerides
-Increase HDL
-Decrease coagulation (clotting)
-Decrease inflammation

6

How do statins lower cholesterol?

Increasing liver LDL receptors that look for extra hepatic cholesterol

7

What prescription meds are a part of cardiac rehab?

-Aspirin
-Lipid lowering agents
-Beta blockers
-ACE inhibitors, AT blockers

8

What does aspirin do to aid in cardiac rehab?

Inhibits platelet formation --> reduces clotting events

9

What do beta blockers do to aid in cardiac rehab?

Lower HR, contractility (kinda the same effect as exercise, but incomplete)

10

What ACE inhibitors and AT blockers do to aid in cardiac rehab?

-Inhibits vasoconstriction
-Enhances vasodilation

11

How does exercise affect coronary blood flow?

Increased coronary blood flow
