Study Notes
Dyspnea
- Dyspnea (shortness of breath) is the feeling of difficulty breathing, often perceived as the inability to take in enough air
- Dyspnea can be acute (occurs over hours to days) or chronic (lasting for more than 4-8 weeks)
- Common causes include cardiac, respiratory, and non-cardiac/pulmonary conditions
Causes of Dyspnea
-
Cardiac Causes:
- Congestive heart failure (CHF)
- Coronary artery disease (CAD)
- Cardiac tamponade
- Cardiomyopathy
- Arrhythmia
- Pericarditis
-
Respiratory Causes:
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Pulmonary embolism
- Pneumonia
- Pneumothorax
-
Non-Cardiac or Pulmonary Causes:
- Normal exertion
- Pregnancy (around 2/3rd trimester)
- Trauma
- Neuromuscular disorders
- Obesity
- Chemical exposure
- Functional causes (anxiety, panic disorders, hyperventilation)
History Taking for Dyspnea and Chest Pain
-
Risk Factors for Cardiac Diseases:
- Smoking
- Hypertension
- Obesity
- Diabetes mellitus
- Age
- Family history
- Dyslipidemia
- Erectile dysfunction
- Stroke
-
Risk Factors for Respiratory Diseases:
- Smoking
- Occupational exposure (e.g., silica or coal)
- Allergen exposure (e.g., birds or dust)
Important Questions to Ask About Dyspnea
- When did the shortness of breath begin?
- Have you experienced shortness of breath before?
- Do you have a diagnosis of COPD or asthma?
- Is shortness of breath present at rest or only during exertion?
- Are there other symptoms like cough, fever, or wheezing?
- Any blood coughed up?
- Is dyspnea associated with chest pain?
Examination
-
Vital Signs:
- Fever (potential indication of pericarditis, pneumonia)
- Differences in blood pressure between arms (possible aortic dissection)
- Decreased oxygen saturation (common in pneumonia, PE, COPD)
- Unexplained sinus tachycardia (potential PE)
-
Neck Examination:
- Tracheal deviation (potential pneumothorax)
- Jugular vein distension (JVD) - tension pneumothorax, tamponade, CHF
-
Chest Wall Examination:
- Lesions (potential herpes zoster)
- Localized tenderness (musculoskeletal)
-
Lung Examination:
- Decreased breath sounds/hyperresonance (potential pneumothorax)
- Lung consolidation (potential pneumonia)
- Wheezing/prolonged expiration (cardiac asthma)
-
Cardiovascular Examination:
- S3 gallop (heart failure)
- S4 gallop (ischemia)
- Pericardial friction rub (pericarditis)
- Muffled heart sounds (tamponade)
- Assessment of distal pulses
-
Neurological Examination:
- Chest pain with neurological findings (potential aortic dissection)
Chest Pain
-
Non-Cardiac Causes:
- Gastroesophageal reflux disease (GERD)
- Musculoskeletal pain
- Pulmonary conditions
- Anxiety or panic attacks
- Esophageal disorders
- Shingles
- Costochondritis
-
Life-Threatening Causes:
- Myocardial infarction (heart attack)
- Aortic dissection
- Pulmonary embolism
- Tension pneumothorax
- Cardiac tamponade
- Severe arrhythmias
- Esophageal rupture
Analysis of Chest Pain
-
SOCRATES (Mnemonic for Chest Pain Evaluation):
- Site: Where is the pain located?
- Onset: When did the pain start?
- Character: What type of pain (sharp, dull, burning)?
- Radiation: Does pain spread to other areas?
- Associated features: Are there other symptoms?
- Time course: How long has the pain lasted?
- Exacerbating/alleviating factors: What makes it worse/better?
- Severity: How intense is the pain?
-
Chest Pain Location:
- Central: Myocardial infarction (MI), pericarditis, pleurisy
- Left side: MI, pericarditis, pleurisy
- Right side: MI, pleurisy
- Inframammary: Neurogenic (e.g., herpes zoster), cervical
-
Onset:
- Abrupt onset with peak intensity at start: Aortic dissection, pneumothorax, PE
- Gradual onset: Ischemia, MI, peptic causes
-
Character:
- Sharp/stabbing: MI, pericarditis, pleurisy, aortic dissection, heartburn, strained muscle
- Squeezing/tightness/pressure: MI, angina, panic attack
- Tearing: Aortic dissection
-
Radiation:
- Jaw: MI
- Neck: Retrosternal goiter, MI
- Left shoulder: MI
- Back: Duodenal ulcer, perforated ulcer
- Intrascapular area: Aortic dissection
-
Associated Symptoms:
- Fever, chills, URI symptoms, productive cough: Pneumonia
- Nausea, vomiting, diaphoresis: MI
- Shortness of breath: PE, pneumothorax (PTX), MI, pneumonia, COPD/asthma
- Asymmetric leg swelling: Deep vein thrombosis (DVT)
- New onset neurologic findings or limb ischemia: Aortic dissection
- Pain with swallowing, acid taste in mouth: Esophageal
-
Time Course:
- 5-15 minutes: Stable angina
- 15+ minutes: MI
- Pain lasting seconds or constantly for weeks is less likely to be caused by ischemia
-
Exacerbating Factors:
- Activity: Ischemic heart disease
- Food: Esophageal
- Lying back: Pericarditis
- Swallowing: Esophageal disease
- Movement: Chest wall pain
- Respiration: PE, PTX, pneumonia, pleurisy
-
Alleviating Factors:
- Rest/cessation of activity: Ischemic
- Nitroglycerin (NTG): Cardiac or esophageal
- Sitting up: Pericarditis
- Antacids: Usually GI system
-
Severity:
- Pain score 0-10 (highly variable between patients)
- 10: Aortic dissection
Investigations
-
Echocardiogram (ECHO): Used to evaluate:
- Acute coronary syndrome (ACS)
- Aortic dissection (ascending)
- Pulmonary embolism
- Tamponade
-
Electrocardiogram (ECG):
- ST segment elevation (early sign of MI)
- New-onset left bundle branch block (MI)
- New T-wave inversion (delayed MI sign)
- Wide Q waves (cardiac death)
Management
-
Immediate Assessment:
- Assess airway, breathing, and circulation (ABCs)
-
Initial Diagnostics:
- ECG obtained within 10 minutes
- Cardiac biomarkers (troponin levels)
- Chest X-ray to rule out pneumonia, pneumothorax, or aortic dissection
-
Further Evaluation:
- Stress testing (for non-acute cases to evaluate for ischemia)
- Echocardiography (if structural heart disease is suspected)
