Chest Pain: Clues That May Point to the Heart or Chest Muscles

Chest pain can come from the heart, muscles, joints, or cartilage, and the sensations can overlap. Clues such as pain with movement or tenderness when pressed may suggest a chest wall cause, while pressure, breathlessness, or pain spreading to the arm or jaw can raise concern about the heart. These patterns can help describe symptoms, but they can’t reliably identify the cause at home.

More than 6.5 million Americans go to an emergency department for chest pain each year, according to a report. Chest discomfort is also the most common symptom of acute heart problems, including heart attacks, according to a review in JAMA. That doesn’t mean every episode signals a heart problem. It does mean that new or unexplained pain is worth taking seriously.

Sameer Amin, M.D., a cardiologist and chief medical officer of L.A. Care Health Plan, says fear about chest pain is understandable. His view is that patients’ concerns deserve attention even when the cause turns out not to be heart-related. Shamail Tariq, M.D., an interventional cardiologist at Providence St. Jude Medical Center in Fullerton, California, and Nneoma Oparaji, M.D., a Houston physician in internal, obesity, and lifestyle medicine, also describe common patterns that may help guide an evaluation.

When the chest wall may be involved

Musculoskeletal pain comes from structures such as muscles, joints, ligaments, or cartilage. Soreness after a harder or unfamiliar workout is one common example. Challenging chest muscles can cause tiny fiber injuries, with delayed onset muscle soreness, or DOMS, developing a day or two later.

A new exercise routine isn’t the only possible trigger. Lifting a heavy box or carrying a child for a long time may strain the chest area, especially when the activity is unfamiliar. Persistent coughing during an illness can also irritate the rib area.

One possible source is costochondritis, inflammation of the cartilage where the ribs meet the breastbone. It can follow exercise or frequent coughing. The Cleveland Clinic estimates that about one in three people who see a doctor for pain around the chest or ribs have this condition.

A specific, tender spot that hurts when touched may fit a chest wall cause. Pain may also be triggered or worsened by twisting, lifting, reaching overhead, coughing, or taking a deep breath. It can last hours or days, according to Tariq. Rest, ice, or heat may ease it; anti-inflammatory medicines such as ibuprofen or naproxen may also help some people, Oparaji says. A clinician or pharmacist can help assess whether a medicine is suitable for an individual.

Patterns associated with heart pain

Many heart-related episodes occur when blood flow to the heart is reduced, often because fatty deposits called plaques narrow the coronary arteries. When the heart muscle receives too little oxygen, the resulting discomfort is called angina.

Stable angina tends to occur with exertion and ease with rest or prescribed treatment. Unstable angina is new, worsening, or persistent despite rest or treatment, Tariq explains. A severe or complete blockage can injure the heart muscle and cause a heart attack. Inflammation around the heart, called pericarditis, is another possible source of heart-related pain.

Heart pain is often described as pressure, tightness, squeezing, or heaviness. It may spread to an arm, shoulder, or jaw, and can occur during physical effort, such as climbing stairs, or during stress. Some people also feel sweaty, short of breath, fatigued, or dizzy. Pericarditis pain may worsen while lying down and ease when sitting up.

Not everyone experiences the familiar heavy pressure. Women and people with diabetes may have symptoms that are easier to mistake for another problem. Tariq says clinicians are moving away from calling these experiences “atypical,” a label that can downplay them. Heart-related symptoms can include upper abdominal discomfort resembling indigestion, or aching or burning in the shoulder, arm, or back. Pain from a heart attack may be mistaken for a pulled muscle, Oparaji says.

Clues help, but they cannot settle the question

Pain that can be reproduced by pressing one spot or that follows a new physical activity may point toward a musculoskeletal cause. Pain that comes and goes, occurs with exertion, or accompanies whole-body symptoms may raise concern about the heart. A recent respiratory illness with frequent coughing can also offer context.

Personal health matters, too. Diabetes, high blood pressure, smoking, a family history of heart disease, or a previous heart event can increase concern. Age and overall health also shape how a clinician weighs the possibilities. Still, no single clue rules a heart problem in or out, and symptoms can differ from person to person.

When to seek care and what evaluation may involve

Amin advises getting new or unexplained chest pain checked, particularly if it lasts more than a few minutes or doesn’t go away. Seek emergency care for severe pain, pain that spreads to the arm, jaw, or back, or pain with trouble breathing, nausea, or lightheadedness. Calling 911 allows paramedics to begin an assessment during transport.

Clinicians typically ask when the pain began, what changes it, and whether the person has heart disease risk factors. They may examine the chest and press on the painful area to see whether that reproduces the symptom. This history and examination help estimate the likelihood of a heart problem; they do not depend on age or a healthy lifestyle alone to rule one out.

If heart trouble is suspected, evaluation may include an electrocardiogram, also called an ECG or EKG, which records the heart’s electrical signals using electrodes placed on the body. A blood test for troponin can look for injury to the heart muscle. Some people may have an exercise stress test, walking on a treadmill while connected to an EKG so clinicians can watch for signs of reduced blood flow. Imaging of the heart or nearby arteries may be considered when needed. No single test gives a complete answer; clinicians interpret findings together.

Tariq says chest pain in women has historically been minimized, in part because symptom research and some treatment equipment have been based largely on male bodies. Care focused on women’s heart health is available, but patients may still encounter dismissive responses. If symptoms remain concerning and the explanation feels incomplete, asking for a clearer discussion or another medical opinion can help. The practical takeaway is simple: describe what you feel, when it happens, and what changes it, and seek prompt assessment when pain is new, unexplained, severe, or accompanied by other symptoms.
