Exercise Prescription for Cardiovascular Flashcards

1
Q

What is the ideal method for determining exercise prescription in cardiovascular disease patients?

A
  • A symptom-limited graded exercise test (GXT) is ideal for determining individualized exercise prescription based on hemodynamic responses like %HRR, %VO2 max, or %VO2 reserve.

Q

What is functional capacity and how is it measured?

A
  • Functional capacity is the heart’s ability to deliver oxygen to tissues, often measured in metabolic equivalents (METs).
  • An increase of 1 MET in functional capacity can reduce all-cause mortality by up to 30%.

Q

What is the recommended exercise intensity for cardiovascular patients?

A
  • Target exercise intensity should be 40-80% of HRR, VO2 max, or VO2 reserve.
  • With an RPE between 12-16 (moderate to hard) on the Borg scale.

Q

When should exercise be terminated in cardiovascular patients?

A

Terminate exercise if:

  • systolic blood pressure (SBP) exceeds 250 mmHg
  • diastolic blood pressure (DBP) exceeds 115 mmHg
  • a decrease in SBP >10 mmHg.

Q

What precautions should be taken for diabetic patients during exercise?

A
  • Initial exercise intensity should be cautious due to the risk of hypoglycemia.
  • Patients with blood sugars < 70 mg/dL should be given a 15g carbohydrate snack and rechecked after 15 minutes.

Q

What is the progression strategy for cardiovascular patients?

A
  • Progress intensity responsibly, as higher intensities yield greater improvements in functional capacity.
  • High-intensity interval training (HIIT) may be beneficial but requires a negative ECG on GXT.

Q

What are the exercise considerations for chronic heart failure (CHF) patients?

A
  • CHF patients are at high risk for exercise-related events and require close monitoring.
  • They should exercise below ICD thresholds, and any worsening of exercise tolerance or ischemia should prompt re-evaluation.

Q

What are the exercise prescription guidelines for peripheral artery disease (PAD)?

A
  • Initial Prescription: Have patients walk at a speed/grade until reaching 3-4 on the claudication scale, rest until pain subsides, and repeat.
  • Goal: Progression aims for sustained walking of 30-50 minutes at 3.0 mph.

Q

How is exercise prescription determined for coronary artery disease (CAD) patients?

A
  • A GXT is essential to determine anginal thresholds and ST-segment displacement.
  • Documentation of resting HR, treadmill speed/grade, session time, and RPE.

A
  • resting HR
  • HR changes
  • treadmill speed/grade
  • session time
  • RPE changes
