Study Notes
Assessment of Cardiovascular Disorders
- Cardiovascular disorders can present as chest pain, fatigue, syncope, exercise intolerance, and cyanosis.
Right-Sided Heart Failure
- Right-sided heart failure occurs when the ventricles are unable to fill or eject blood in adequate amounts to meet the body's needs.
- Blood backs up into the venae cava, causing congestion of the venous system.
- Signs and symptoms include chest pain, fatigue, syncope, exercise intolerance, and cyanosis.
- Risk factors include myocardial infarction, lung disease, pulmonary hypertension, and pulmonary embolism.
Left-Sided Heart Failure
- Left-sided heart failure occurs when the ventricles are unable to fill or eject blood in adequate amounts to meet the body's needs.
- Pressure builds in the pulmonary veins, causing blood to back up into the pulmonary vasculature and lungs.
- Signs and symptoms include chest pain, dyspnea with tripod positioning, fatigue, syncope, exercise intolerance, and cyanosis.
- Risk factors include myocardial infarction, hypertension, arrhythmia, and valvular disease.
Physical Exam Findings and Assessment Techniques
- Assess heart rate, as tachycardia may be present.
- Palpate pulse strength, as it may be absent or changed.
- Assess skin signs, such as pale, cool, cyanotic, or diaphoretic.
- Check for jugular vein distention and bilateral pedal edema.
- Assess lung sounds, which may be clear or present with adventitious sounds.
Pulsus Paradoxus
- Pulsus paradoxus is a positive finding when systolic BP drops more than 10 mmHg and heart rate increases during inhalation.
- Pulse strength may decrease, be asymmetric, or become absent.
Differential Diagnosis
- Myocardial infarction
- Left-sided heart failure
- Pulmonary embolism
- Thoracic aortic aneurysm and dissection
- Abdominal aortic aneurysm and dissection### Cardiac Tamponade
- Fluid accumulation in the pericardial sac surrounding the heart causes compression of the thin-walled right ventricle, limiting its filling and potentially encroaching on the left side of the heart.
- Compression compromises cardiac output.
- Medical causes of cardiac tamponade include cancer, bacterial infections, recent myocardial infarction, autoimmune disorders, and hemopericardium.
- Signs and symptoms: chest pain, cough, and dyspnea.
- Risk factors: cancer (lung, breast, lymphoma), bacterial infections, recent myocardial infarction, autoimmune disorders (e.g. systemic lupus erythematosus), and hemopericardium.
Abdominal Aortic Aneurysm (AAA) and Dissection
- An enlargement of part of the aorta caused by weakness in the vascular wall.
- Most aneurysms do not rupture, leak, or dissect, but less than half of patients exhibit the classic triad of symptoms.
- Consider AAA in patients with syncope or any one of the triad of symptoms.
- Patients with AAA have a 50% mortality rate even when reaching the hospital alive.
- Any patient suspected of experiencing a dissection should be moved with care and transport should not be delayed.
- Signs and symptoms: triad of (1) hypotension, (2) abdominal or tearing back pain, and (3) pulsatile abdominal mass.
- Risk factors: male, smoking, atherosclerosis, uncontrolled hypertension, Marfan Syndrome, Ehlers-Danlos Syndrome, drugs (methamphetamine, cocaine, fentanyl), and recent abdominal trauma.
- Pertinent vital signs and diagnostics: acquire a 12-lead ECG, assess blood pressure, and hypotension (SBP < 100).
