Disease Description (Causes and Symptoms)
- Definition: A general term for pain or discomfort felt in the chest area; its clinical significance and treatment vary greatly depending on the cause.
- Main causes (examples): Ischemic heart disease (angina·myocardial infarction), aortic disease (dissection·aneurysm), valvular disease, cardiomyopathy, pulmonary embolism, pneumothorax, pulmonary infection·lung cancer, pleuritis, musculoskeletal pain, gastroesophageal reflux/esophageal spasm, panic disorder, etc.
- Pathophysiology summary: The mechanism of pain differs by cause — myocardial ischemia causes chest pressure·tightness through stimulation by metabolites and receptors; aortic dissection causes severe tearing pain (aortic intimal rupture/bleeding); pulmonary embolism causes chest pain·shortness of breath·hypoxia due to reduced pulmonary blood flow.
- Main symptom characteristics: Chest pressure·tightness·stabbing pain, radiation to the neck·jaw·shoulder·arm, shortness of breath, cold sweats, dizziness or fainting, cough·hemoptysis, etc. The character and onset pattern of the pain (worsening with exertion, persisting at rest, etc.) and accompanying symptoms are important for diagnosis.
- Emergency signs (immediate emergency care recommended): Sudden and very severe pain, altered consciousness, shortness of breath, fainting·severe dizziness, or a history or family history of coronary artery disease, etc.
Treatment Methods
- General principles: Rapid diagnosis and treatment according to the underlying cause are essential, in addition to relieving the chest pain itself. The standard approach for each cause should be applied first.
- Myocardial infarction/acute coronary syndrome: After rapid evaluation (electrocardiogram·cardiac enzymes), standard treatment — antiplatelet agents such as aspirin, oxygen therapy (in cases of hypoxia), anticoagulants, vasodilators (such as nitroglycerin; indications must be confirmed), drug therapy including beta-blockers·statins, and immediate percutaneous coronary intervention (PCI) for ST-segment elevation or thrombolysis when indicated.
- Unstable angina·NSTEMI: Consider antithrombotic·anticoagulant treatment and coronary intervention after risk assessment.
- Aortic dissection: If suspected, immediately classify it with imaging (CT angiography); ascending aorta (type A) requires emergency surgery, while descending aorta (type B) requires blood pressure·heart rate control and consideration of medical/endovascular treatment.
- Pulmonary embolism: Anticoagulant treatment (low-molecular-weight heparin or direct oral anticoagulants); thrombolysis or thrombectomy for massive embolism.
- Pneumothorax: Observation·oxygen therapy for small, asymptomatic cases; chest tube drainage·needle aspiration or surgery for symptomatic or tension pneumothorax.
- Pulmonary infection·lung disease·lung cancer: Cause-specific treatment such as antibiotics, anticancer treatment·radiation·surgery.
- Musculoskeletal·chest wall pain: Nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, and activity modification.
- Panic disorder·anxiety-related chest pain: Psychotherapy (cognitive behavioral therapy), medication (antidepressants·short-term benzodiazepines, etc.)
- Lifestyle management: Smoking cessation, control of hypertension·diabetes·hyperlipidemia, weight management, and regular exercise (according to a doctor's instructions).
- Precautions: An emergency department visit is recommended if the cause is unclear or there are cardiac·respiratory-related findings. Medication·procedures should follow the specialist's judgment.
Checklist Before an Outpatient Visit (Including Example Questions)
- What to bring: A list of all currently taken medications (including prescriptions·over-the-counter medicines·supplements), allergy history, past medical history (heart disease·surgery·lung disease, etc.), and recent test results (electrocardiogram·blood tests·imaging, with copies if possible).
- Symptom record: Exact time the pain began, character of the pain (pressure·burning·stabbing, etc.), pain intensity (0–10), duration and frequency, triggers (exercise·meals·breathing·position), relieving factors, and accompanying symptoms (shortness of breath·sweating·nausea·fainting·radiation to the arm·jaw).
- Lifestyle habits: Smoking status, alcohol use, occupation (level of physical activity), stress level, and sleep patterns.
- Preparation for tests: If available, record and bring recent measurements of blood pressure·heart rate·body temperature·oxygen saturation.
- Example questions (questions for the patient to ask the doctor in advance):
- “What are the criteria for going to the emergency department if my current pain becomes severe?”
- “Do the medications I am taking affect the tests or treatment?”
Examples of General Questions to Ask the Doctor
- What are the expected effects and side effects of this medication?
- Which tests (electrocardiogram·echocardiogram·blood tests·CT, etc.) are needed, and why?
- How urgent is the treatment (emergency/outpatient/follow-up), and what is the prognosis?
- Which lifestyle habits should I stop or make sure to follow?
Examples of Condition-Specific Questions
- If ischemic heart disease is suspected: “Which tests (electrocardiogram·troponin test) should I undergo and when to determine whether I have a myocardial infarction? In what situations is immediate treatment in an emergency, such as percutaneous coronary intervention, needed?”
- If aortic dissection is suspected: “When I have severe tearing chest pain, is CT angiography immediately necessary? How quickly should my blood pressure and heart rate be lowered, and which medications are used?”
