Slide 1

ACSM’s Guidelines For Exercise Testing And Prescription : Chapter 2Health Screening& Risk Stratification

David Arnall, Ph.D., P.T., FACSM, ES

Slide 2

Reasons To Screen Your Exercising Population

  • Identify and exclude individuals with medical contraindications to exercise

  • Identify individuals with risk factors who need to be seen by a physician before undertaking an exercise program.

Slide 3

  • Identify individuals with significant disease who should only exercise in a medically supervised environment.

  • Identify individuals with other special needs such as orthopedic problems, neurological conditions, etc.

Slide 4

Physical Activity Readiness Questionnaire - The PAR-Q

  • This questionnaire was first developed in Canada and is used widely to assess the readiness of individuals to undertake a moderately vigorous physical exercise program.

Slide 5

PAR-Q

  • Common sense is your best guide in answering these few questions. Please read them carefully and check the yes or no box.

    http://www.d.umn.edu/student/loon/soc/phys/par-q.html

Slide 6

Questions On The PAR-Q To Ask Potential Exercising Persons

  • 1. Has your doctor ever said that you have heart trouble ?

  • 2. Do you frequently have pains in your heart and chest ?

Slide 7

  • 3. Do you often feel faint or have spells of severe dizziness?

  • 4. Has a doctor ever said your blood pressure was too high?

Slide 8

  • 5. Has your doctor ever told you that you have a bone or joint problem such as arthritis that has been aggravated by exercise, or might be made worse with exercise?

Slide 9

  • 6. Is there a good physical reason not mentioned here why you should not follow an activity program even if you wanted to?

  • 7. Are you over age 65 and not accustomed to vigorous exercise?

Slide 10

  • If the person filling out the PAR-Q answers YES to any of the questions, they are advised to see their physician and find out if they are able to exercise safely in a community exercise program.

Slide 11

  • If the person filling out the PAR-Q answers NO truthfully to all of the questions, they are reasonably assured that they can have a fitness appraisal evaluation and begin an exercise program as long as they start out slowly and gradually advance the intensity of their exercise.

Slide 12

Coronary Risk Factors To Be Used With ACSM’s Risk Stratification

  • Family History - MI, coronary revascularization or sudden death before the age of 55 years in the father or other first-degree relative (son, brother) or before the age of 65 years in the mother or other first-degree relative (sister, daughter).

Slide 13

  • Cigarette Smoking - current use or those who have quit within the last 6 months (other tobacco use - pipe, cigars, etc.)

Slide 14

  • Hypertension - Blood pressure on two separate occassions > 140/90 or an individual who is on medications for hypertension

Slide 15

  • Hypercholesterolemia

    • Total Serum Cholesterol > 200 mg/dl

    • Low-Density Lipoproteins > 130 mg/dl

    • High-Density Lipoproteins < 35 mg/dl

    • On Lipid Lowering Medications

Slide 16

  • Impaired Fasting Glucose- > 110 mg/dl measured on 2 separate occassions.

Slide 17

  • Obesity - Body mass Index > 30 Kg/m2 or waist girth > 100 cm.

    There are many health professionals which disagree about what marker of obesity to use. Therefore, use your best clinical judgement when evaluating this risk factor.

Slide 18

  • Sedentary Lifestyle - Persons who are not involved with a regular exercise program†.

    † Persons not accumulating 30 + minutes of exercise on most days/week

Slide 19

Additional Concerns …...

  • Major Signs & Symptoms Of Cardiopulmonary Disease Are :

    • Chest Pressure/Pain Or Other Anginal Equivalents

    • SOB At Rest Or Mild Exercise

    • Dizziness Or Syncope

    • Orthopnea Or Paroxysmal Nocturnal Dyspnea

Slide 20

  • Ankle Edema

  • Palpitations Or Tachycardia

  • Intermittent Claudication

  • Heart Murmurs

  • Unusual Fatigue Or SOB With Usual Activities

Slide 21

ACSM Risk Stratification

  • Low Risk- Men under 45 yrs and women under 55 yrs. Who are asymptomatic and have no more than one risk factor (HTN, Obesity, Hypercholesterolemia, Family Hx.)

Slide 22

  • Moderate Risk - Men > 45 yrs and women > 55 yrs or if these persons have two or more risk factors.

Slide 23

  • High Risk- Persons with one or more signs or symptoms (ankle edema, orthopnea, SOB, angina, etc.) or known cardiovascular, pulmonary (COPD) or metabolic disease (DM).

Slide 24

  • Now that the patient has been screened and evaluated as to their potential risk, there are other decisions that the exercise leader must make.

Slide 25

Definitions…...

  • Moderate Exercise : This intensity is defined as any activity that is between 3-6 METs.

  • An exercise that is equivalent to brisk walking at 3-4 mph.

  • An exercise that can be comfortably sustained for 45 minutes.

Slide 26

  • Vigorous Exercise : Activities > 6 METs

  • A substantial cardiorespiratory challenge sustainable for 20-30 min.

Slide 27

The Two Golden Questions

  • Does my patient need a physical exam and an exercise test prior to starting an exercise program ?

  • Does the physician need to be present when I perform the exercise test ?

Slide 28

Does The Patient Need A Physical, An Exercise Test & Does The Physician Need To Be Present ?

Slide 29

What If They Are Already Cardiac Patients ?

  • Low Risk

    • Ejection fraction > 50%

    • No resting or exercise-induced dysrhythmias

    • Asymptomatic & have no angina with exertion or recovery

    • Functional work capacity > 7 METs

    • Normal hemodynamics

    • No clinical depression

Slide 30

  • Moderate Risk

    • Ejection fraction between 40% - 49%

    • Signs/symptoms including angina at moderate levels of exercise (5-6.9 METs) or in recovery.

Slide 31

  • High Risk

    • Ejection fraction < 40%

    • Survivor of cardiac arrest/sudden death

    • Complex ventricular arrhythmia at rest or exercise

    • Abnormal hemodynamics

    • Signs/symptoms with low level exercise

    • Functional capacity < 5 METs

    • Significant clinical depression

Slide 32

  • Risk factor stratification can be modified with :

    • exercise training

    • risk factor reduction

    • lipid lowering drugs, nitrates, -blockers

    • surgical intervention (CABG, PTCA)

    • thrombolysis (streptokinase, TPA)

    • stress reduction - counseling & drugs

Slide 33

  • With cardiac patients, do I have an algorhythm to determine if they need a physical exam and an exercise test with a physician present prior to undertaking an exercise program ?

  • The answer is NO !! A physician must examine, test and clear a cardiac patient prior to exercising.
