Study Notes
Heart Failure Functional Status Assessment
-
Assessing functional status is helpful for follow-up and monitoring of heart failure patients.
-
The New York Heart Association (NYHA) classification framework is used to assess heart failure severity and functional status.
-
NYHA classification can be used for patients with preserved ejection fraction and reduced ejection fraction.
Common Presenting Symptoms of Cardiovascular Disease
- Shortness of Breath (SOB) / Dyspnea on Exertion (DOE): Can be a sign of Angina equivalent (Coronary Artery Disease), Aortic Stenosis (AS) or Hypertrophic Obstructive Cardiomyopathy (HOCM) due to decreased cardiac output.
- Edema / Peripheral Edema: Many conditions can cause peripheral edema, including Heart Failure, Venous Insufficiency, Thrombophlebitis, Renal Disease, Hepatic Disease, Trauma, Tumors, and Inflammation.
- Chest Pain / Discomfort:
- In some cases, blood pressure may remain elevated during exertion, which may be a sign of cardiovascular disease.
- Bendopnea (Dyspnea on bending forward) can be associated with elevated filling pressures and low cardiac index, but it is not diagnostic of heart failure and can occur in other conditions.
Perfusion Status
- Clinical examination for perfusion status can be unreliable.
- Cool extremities and narrow pulse pressure may suggest inadequate perfusion.
Exercise Stress Test
- Evaluates heart function during physical exertion.
- Can reveal coronary artery disease that is not apparent at rest.
Chest Pain Risk Factors
- Chest pain that feels like pressure, is worse than previous episodes of angina, occurs during exertion, and is accompanied by nausea or sweating, or radiates to the arms/shoulders may indicate a higher risk of acute coronary syndrome (ACS).
Low to Intermediate Risk Patients
- Low-intermediate risk patients who do not require immediate referral can be assessed with exercise stress testing, coronary CT angiography, or cardiac MRI.
Cardiac Auscultation
- Auscultate for murmurs in infants in a quiet location while they are lying on their back and at rest.
- Innocent murmurs in infants are commonly attributed to peripheral pulmonic stenosis or PDA closure.
- These murmurs typically resolve between 3-6 months.
Palpation in Children
- When palpating the chest of older children, identify the point of maximal impulse (PMI).
- Note if the PMI is shifted from its usual location, which could be a sign of an enlarged ventricle.
Murmur Characteristics
- Timing and duration of murmur
- Pitch
- Intensity
- Pattern
- Quality
- Location
- Radiation
- Variation with respiratory phases
Physical Exam Findings Concerning for Cardiac Abnormalities
- A displaced PMI to the left could be a sign of an enlarged ventricle
- Jugular venous distention (JVD) could indicate fluid volume overload, such as right heart failure (RHF).
Factors Influencing ACS Risk
- Factors such as age, sex, and type of chest pain can help predict the likelihood of coronary artery disease (CAD).
- Clinical decision rules like the Marburg Heart Score and INTERCHEST rule can aid in estimating ACS risk.
Infant Murmurs
- Thorough review of family and obstetric history is critical for infants with murmurs.
- Screen all infants for complex congenital heart disease with pulse oximetry.
- Leaning forward while seated can bring the heart closer to the chest wall, making findings more noticeable.
Physical Examination
- Inspect the precordium:
- Apical impulse
- Pulsations
- Heaves or lifts
Echocardiogram
- Can be used in primary care settings.
- Ultrasound imaging of the heart.
- Assesses both structure and function.
- Detects changes in heart size (normal vs dilated).
- Left and right ventricular (LV and RV) wall thickness.
- Ejection fraction (EF) – left ventricle (LV):
- Preserved EF is 55-77%
- Reduced EF is less than 50%.
Physical Exam Findings
- Common physical findings like rales (lung sounds) and peripheral edema are not always reliable indicators of heart failure, especially in advanced stages.
- Most murmurs in children are innocent and not associated with heart disease.
- Distinguishing innocent from pathologic murmurs is challenging for clinicians.
- Referrals to pediatric cardiologists are common due to this difficulty.
