Short answer

Internal Medicine(내과) is generally the first department to visit for chest tightness and pain, as it can broadly evaluate cardiac, respiratory, and digestive causes. Depending on what is found, you may be referred to Cardiology(심장내과), Pulmonology(호흡기내과), or other specialties for further evaluation.

Which department

  1. 1Internal Medicine (내과)
    Internal Medicine covers a wide range of causes behind chest discomfort, including heart, lung, digestive, and stress-related issues. Because chest symptoms often overlap across multiple organ systems, internists are generally trained to assess and triage these symptoms first. — First / second line: Starting at a local clinic (의원) in Internal Medicine is generally appropriate for mild-to-moderate chest tightness without severe or sudden symptoms. If further evaluation is needed, the internist will typically issue a referral letter (진료의뢰서) to a hospital-level specialist.
  2. 2Cardiology (심장내과)
    Cardiology specializes in heart-related causes of chest pain, such as issues involving the heart muscle, valves, or circulation. Chest tightness that worsens with exertion or is accompanied by palpitations or shortness of breath is often evaluated here. — First / second line: You may be referred to Cardiology from Internal Medicine, or you may go directly to a hospital-level department if your symptoms are more acute or if a cardiac cause is strongly suspected. Secondary-tier hospitals (병원/종합병원) can be visited directly with normal health insurance coverage — no referral letter is required for standard coverage there.
  3. 3Pulmonology (호흡기내과)
    Pulmonology handles chest symptoms related to the lungs and airways, such as tightness caused by respiratory conditions, airway inflammation, or fluid around the lungs. If chest discomfort is accompanied by cough, wheezing, or difficulty breathing, a pulmonologist may be consulted. — First / second line: Pulmonology is typically reached through a referral from Internal Medicine, especially when respiratory symptoms are prominent alongside chest discomfort.
  4. 4Gastroenterology (소화기내과)
    Chest tightness is sometimes caused by digestive issues such as acid reflux or esophageal problems, which can closely mimic heart-related pain. Gastroenterology evaluates these possibilities, particularly when symptoms appear after meals or in a lying-down position. — First / second line: Gastroenterology is usually considered after a cardiac cause has been assessed or ruled out by Internal Medicine or Cardiology, and when digestive symptoms are prominent.

Go to the ER / call 119 if

If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).

  • Sudden, severe chest pain that spreads to the left arm, jaw, neck, or back — go to the emergency room or call 119 immediately.
  • Chest pain accompanied by difficulty breathing, cold sweats, or a feeling of impending doom — do not wait; go to the emergency room.
  • Chest tightness with loss of consciousness, fainting, or sudden extreme dizziness — call 119 right away.
  • Coughing up blood alongside chest pain — seek emergency care without delay.
  • Chest pain that is persistent, worsening rapidly, or does not ease at all within a short time — go to the emergency room rather than waiting for a regular appointment.

Before your visit

  • Note when the chest tightness or pain started and how long each episode typically lasts.
  • Observe whether symptoms appear at rest, during physical activity, after eating, or in specific postures, and bring those observations to your visit.
  • List any accompanying symptoms, such as shortness of breath, palpitations, sweating, nausea, or coughing.
  • Bring a list of all current medications, supplements, and any known allergies to share with the doctor.
  • If you have had any previous tests related to heart or lung conditions (e.g., ECG results, chest X-rays, blood tests), bring those records or reports.
  • Think about relevant medical history such as high blood pressure, high cholesterol, diabetes, smoking history, or a family history of heart disease.

General principles

Chest tightness and pain can originate from several organ systems — most notably the heart, lungs, esophagus, and musculoskeletal structures — which is why Internal Medicine is typically the starting point in the Korean healthcare system. Because symptoms from these different sources can look similar, the initial clinical assessment aims to narrow down the likely origin before directing the patient to a more focused specialist.

In Korea, the general flow is to begin at a local clinic (의원) for a first evaluation, where the doctor may perform basic assessments and, if needed, issue a referral letter (진료의뢰서) for a higher-level specialist. Visiting a tertiary hospital (상급종합병원) directly without a referral is possible but may result in higher out-of-pocket costs under the national health insurance (건강보험) system.

Diagnostic approaches for chest symptoms generally involve assessing symptom patterns, timing, and associated signs alongside basic investigations — the specific approach is determined by the attending physician based on individual presentation. The goal of the initial visit is not necessarily to diagnose on the spot, but to determine the appropriate next step in evaluation.

FAQ

Should I go to a local clinic (의원) or a larger hospital for chest tightness?

Generally, a local clinic is the appropriate first step for non-emergency chest symptoms, as it is more accessible and cost-effective under Korean health insurance. If the clinic doctor determines that more advanced evaluation is needed, they will provide a referral letter to guide you to the right hospital-level department.

How do I know if my chest pain is from the heart or from digestion?

Heart-related and digestive chest symptoms can feel very similar and are difficult to distinguish without medical evaluation. A doctor will typically consider factors such as when symptoms occur, what makes them better or worse, and associated symptoms — this is best assessed in person rather than self-diagnosed.

What kinds of tests are generally done for chest tightness?

The types of tests used for chest symptoms vary widely depending on the doctor's clinical assessment and the suspected cause. Common general approaches may include heart rhythm checks, imaging of the chest, or blood tests, but the specific tests ordered are always determined by the physician based on your individual situation.

Is chest tightness evaluated differently for older adults or children?

The range of possible causes and how symptoms present can differ across age groups, so doctors take age into account when assessing chest discomfort. For older adults, cardiac causes are generally given higher priority in the evaluation; for children and younger patients, respiratory or musculoskeletal causes may also be considered more prominently — a physician will guide the appropriate approach.
