MEDICAL CHART REVIEW

 Other therapeutic regimens

 Electrocardiogram and telemetry monitoring

 Pulmonary function test

 Arterial blood gases

 cardiac catheterization data

 Other diagnostic tests

 Vital signs

 Hospital course since admission.

 Occupational history

 Home environmental assessment

2. Patient/family interview

• establishing relation with the patient and family,

• discerning their level of understanding of the medical problem(s), and

• their goals and expectations for rehabilitation

.

Typically, interview questions should be open ended and straightforward. For example

• What prompted you to come to the hospital/seek physical therapy?

• Do you ever have problems with shortness of breath, chest pain or discomfort, lightheadedness or dizziness, getting tired easily, palpitations, etc.?

• Do you experience any type of discomfort or pain with exertion? If it occurs during ambulation, at what distance, speed, or incline? What about stairs?

• Can you describe your symptoms for me?

• What brings on your symptoms? What kinds of things are you doing immediately before or at the time of the onset of your symptoms?

• Are your symptoms aggravated by certain positions, such as lying flat or on one side or the other?

• How long have you had these symptoms?

• Do the symptoms interfere with things you would like to do? Such as?

• Have you discovered any ways to relieve the symptoms?

• What has your doctor told you about your problem?

• Have you ever received physical therapy for this problem or any other problem?

• Have you ever smoked? How much and for how long?

• What would you say your major difficulty is right now?

• What would you like us to work on before you go home?

• What are your goals for your recovery?

3. Physical examination

• General appearance Obesity, cachexia, barrel-shaped chest, signs of breathing difficulty (e.g., tachypnea, use of accessory muscles of respiration, intercostal retractions)

• Vital signs increase or decrease heart rate, blood pressure, or respiratory rate; presence of fever

• Skin Cold and clammy in low-cardiac output states; pale, blue, and cold if peripheral vasoconstriction;

• Cyanosis (peripheral or central) if marked arterial hypoxemia; or xanthomas in familial hypercholesterolemia

• Head, eyes, ears, nose, and throat (HEENT)

• Abnormal funduscopic eye examination (e.g., retinal arteriolar changes in hypertension HTN and DM)

• Abnormal neck examination (e.g., jugular venous distension in right or biventricular heart failure, exaggerated venous pulse waves in pulmonary HTN or right-sided valvular disease, or prominent carotid pulsations in aortic incompetence)

• Signs of upper respiratory infection (which might be seeding lower respiratory tract)

• Chest, lungs Abnormal chest examination (e.g., decrease chest or diaphragmatic excursions in chronic obstructive pulmonary disease, prominent pulsations in cardiac hypertrophy, thrills in valve disease)

• Abnormal breath sounds (e.g., decreased, bronchial, or adventitious breath sounds

• Cardiovascular Abnormal heart sounds (e.g., murmurs in valvular disease, third and/or fourth heart sounds

• if diastolic dysfunction or reduced ventricular compliance, friction rubs in pericarditis

• Abnormal peripheral pulses (e.g., decreased if atherosclerotic disease or aortic stenosis, bounding in aortic incompetence)

• Abdomen Enlarged liver and spleen, ascites in right heart failure

• Extremities Abnormal extremity examination (e.g., peripheral edema, digital clubbing)

Sign or Symptom of Cardiovascular diseases

• Chest pain or discomfort due to mismatch between myocardial oxygen supply and demand (due to coronary disease, LV hypertrophy, LV outflow obstruction, coronary spasm, microvascular angina), autonomic dysfunction, MV prolapse

• Claudication due to peripheral arterial disease with mismatch between peripheral O2 supply and demand

• Clubbing of digits due to right-to-left shunting in congenital heart disease

• Cough due to acute pulmonary edema, MS

• Cyanosis due to right-to-left shunting in congenital heart disease, significant decrease cardiac output

• Dizziness due to inadequate cardiac output resulting in # perfusion of the brain (due to LV dysfunction, LV outlet obstruction, arrhythmias, blood pooling in lower extremities)

• Dyspnea due to pulmonary venous pressure caused by LV diastolic or systolic dysfunction (due to coronary ischemia, hypertension, valvular disease, cardiomyopathy), peripheral arterial disease with lactic acidosis

• Edema due to " Systemic venous pressure due to " RA pressure (e.g.,

LV failure, MS, cor pulmonale, TS, TR, constrictive pericarditis)

• Fatigue due to low cardiac output (due to LV dysfunction, LV outlet obstruction, arrhythmias), drugs

• Hemoptysis due to acute pulmonary edema, MS

• Hypotension due to decrease cardiac output, vasodilation

• Jugular venous distension due to increase systemic venous pressure caused by increase RA pressure (see preceding entry for

Edema)

• Nocturia due to CHF with peripheral edema

• Orthopnea In CHF, SOB when lying flat due to increase pulmonary venous pressure caused by increase venous return to heart, which is not able to handle increase workload

• Palpitations due to arrhythmias

Paroxysmal nocturnal dyspnea In CHF, sudden onset of SOB that awakens patient at night because of " pulmonary pressures caused by the gradual reabsorption of edema fluid from the LEs (which are no longer dependent), resulting in " venous return to heart, which is not able to handle " workload

Functional Classification of Heart Disease

Functional Classification , Exercise Tolerance , Description Approximate

 I (6 –10 METs) Patient with cardiac disease but without any resulting limitations of physical activity; ordinary physical activity does not cause undue fatigue, palpitations, dyspnea, or anginal pain

 II (4 –6 METs) Slight limitations of physical activity; comfortable at rest, but ordinary physical activity results in fatigue, palpitations, dyspnea, or anginal pain

 III (2 –3 METs) Marked limitation of physical activity; comfortable at rest, but less than ordinary physical activity causes symptoms, as above

 IV (<2 METs) Unable to carry out any physical activity without discomfort; symptoms of cardiac insufficiency or of angina may be present even at rest; if exertion is undertaken, discomfort increase

Cardiovascular Diagnostic Tests and Procedures

1) Arterial blood gases (ABGs)

• Is oxygenation normal (Pao2 >80 with O2 saturation [SaO2] >97%) or adequate (PaO2 >60 with SaO2 >90%)? If SaO2 <85%, exercise is usually contraindicated.

• Are PaCO2 and pH within normal limits (35–45 mm Hg and 7.35–

7.45, respectively)?

• Are alterations acute or chronic ?

• Was the patient receiving supplemental oxygen when the ABGs were drawn?

• Does the patient need oxygen during treatment?

2)Cardiac catheterization

 Are the chamber and vessel pressures normal?

 Are there any gradients across the valves?

3) Ventriculography

 Is ventricular performance normal (EF >40%–50%, normal wall motion)?

 Is there evidence of valvular regurgitation?

4) Angiography

 Are there any obstructions in the coronary arteries?

 If so, how many, in which vessels, and to what degree? Are coronary artery bypass grafts patent?
