Most chest pain is not a heart attack. Only about 13% of emergency room visits for chest pain turn out to be an acute cardiac event, according to CDC data. That said, chest pain always deserves attention because the causes range from completely harmless muscle strain to life-threatening emergencies. The sensation you’re feeling could come from your heart, your lungs, your digestive system, your rib cage, or even stress and anxiety.
When Chest Pain Is an Emergency
Some types of chest pain require immediate action. Call 911 if you experience pressure, tightness, or squeezing in your chest that lasts more than a few minutes or keeps coming and going, especially if it comes with pain spreading to your shoulder, arm, back, neck, jaw, or teeth. Nausea, vomiting, sudden shortness of breath, lightheadedness, or breaking into a cold sweat alongside chest discomfort are all warning signs of a heart attack.
A less common but equally dangerous possibility is aortic dissection, where the wall of your body’s largest artery tears. This produces sudden, severe chest or upper back pain that people often describe as tearing or ripping. It hits hard and fast, which distinguishes it from the more gradual buildup of heart attack pain.
Pulmonary embolism, a blood clot in the lungs, is another emergency. It typically causes sudden shortness of breath that worsens with activity, along with chest pain, a rapid heartbeat, coughing (sometimes with blood), and dizziness or fainting. Leg pain or swelling, particularly in one calf, can be an early clue.
Heart-Related Causes
When chest pain actually originates from the heart, there are a few distinct patterns. Stable angina happens when your heart muscle temporarily doesn’t get enough blood, usually during physical exertion or stress. It feels like pressure, heaviness, or aching behind the breastbone. Many people describe it as discomfort rather than outright pain. It typically eases within a few minutes once you rest.
Unstable angina is more concerning. The pattern shifts: episodes become more frequent, more severe, or start happening at rest rather than only during activity. The discomfort can radiate to either shoulder, down the inside of either arm, through your back, or into your jaw and teeth. Unstable angina doesn’t cause permanent heart damage the way a heart attack does, but it signals that a heart attack could follow.
During an actual heart attack, the pain is similar to angina but more intense, longer lasting, and not relieved by resting. It centers in the middle of the chest and can spread to the back, jaw, or left arm. Some people feel it in the abdomen and mistake it for severe indigestion.
Heart Pain That Changes With Position
Pericarditis, inflammation of the thin sac surrounding your heart, produces sharp chest pain behind the breastbone that can radiate to your back, neck, or arms. The key distinguishing feature: the pain gets worse when you lie down or take a deep breath, and it improves when you sit up and lean forward. This positional quality is unusual for heart attacks and helps doctors tell the two apart.
Why Women Often Experience Different Symptoms
Women having a heart attack frequently don’t get the classic “clutching the chest” presentation. About 85% of women in one study presented with what doctors call atypical symptoms: shortness of breath, nausea, vomiting, dizziness, sweating, back pain, and fatigue. Women were significantly more likely than men to experience these non-chest symptoms. When women did have chest pain, they more often described it as squeezing or tightness rather than the burning or pressure men commonly reported. Women also tended to feel pain in the upper chest and between the shoulder blades more than men did.
This matters because these vague symptoms are easy to dismiss. Older adults and people with diabetes can also have minimal or no chest pain during a heart attack, making any unexplained combination of the symptoms above worth taking seriously.
Digestive Causes That Feel Like Heart Pain
Acid reflux is the single most common cause of non-cardiac chest pain. When stomach acid backs up into your esophagus, it burns the lining, and because your esophagus runs directly through your chest, you feel it right behind your breastbone. The sensation can be intense enough to genuinely mimic a heart attack. If the pain tends to follow meals, gets worse when you lie down, or comes with a sour taste in your mouth, reflux is a strong possibility.
Gas and bloating can also produce chest pain when trapped gas in your stomach travels upward into the esophagus instead of moving through your intestines. This type of pain often shifts around, feels better after belching, and lacks the radiating quality of cardiac pain.
Muscle and Rib Pain
Costochondritis is inflammation where your ribs connect to your breastbone. It’s one of the most common causes of chest pain, and it can feel alarmingly similar to a heart problem because the tenderness sits right over the center of your chest. The hallmark of costochondritis is that you can reproduce the pain by pressing on the spot where it hurts. Pushing on the area where one or two ribs meet the sternum typically triggers recognizable tenderness.
Doctors sometimes use specific physical maneuvers to confirm it. Extending your neck upward while someone gently pulls your arms back, or flexing one arm across your chest while turning your head toward that shoulder, can recreate the pain if costochondritis is the cause. Your heart rate, blood pressure, EKG, and chest X-ray will all look normal. It’s worth knowing, though, that tenderness on pressing doesn’t completely rule out a cardiac problem, so costochondritis is considered a diagnosis doctors reach after excluding more dangerous causes first.
Anxiety and Panic-Related Chest Pain
Panic attacks, anxiety, and depression can all produce real, physical chest pain. This isn’t imaginary. Anxiety triggers your body’s stress response, which tightens muscles, speeds up your heart rate, and can cause sharp or aching sensations in your chest. People with anxiety disorders and other conditions involving heightened pain sensitivity are especially prone to this.
Panic-related chest pain often comes on suddenly alongside a racing heart, tingling in the hands, difficulty breathing, and a sense of dread. It typically peaks within 10 to 20 minutes and then fades. The overlap with heart attack symptoms is significant enough that many people end up in the emergency room, and that’s a reasonable response, especially the first time it happens.
What Happens If You Get It Checked
If you go to an emergency room or urgent care with chest pain, the first step is usually an EKG, which measures your heart’s electrical activity and can reveal an ongoing heart attack within minutes. Blood tests check for a protein called troponin, which heart muscle cells release when they’re damaged. High-sensitivity versions of this test can detect even small amounts of injury and are the current standard for confirming or ruling out a heart attack.
If those initial tests are normal but your doctor still suspects a heart-related cause, imaging tests like an echocardiogram (ultrasound of the heart) or a CT scan of the coronary arteries may follow. For suspected reflux, a trial of acid-reducing medication that resolves the pain is often enough to confirm the diagnosis without further testing.
The combination of your symptoms, their timing, what makes them better or worse, and these test results usually points to a clear answer. Many people with chest pain leave the hospital the same day with reassurance and a straightforward treatment plan.
