Chest Pain and Other Cardiovascular Causes
Chest pain is a common symptom that can be caused by various conditions, many of which are related to the cardiovascular system. While chest pain is often associated with heart attacks, it can also be caused by other cardiovascular causes.
Understanding these causes can help individuals seek appropriate medical attention and treatment. In this article, we will explore some of the common cardiovascular causes of chest pain.
Coronary Artery Disease (CAD)
Coronary artery disease (CAD) is a condition that occurs when the blood vessels supplying the heart become narrow or blocked. This can restrict blood flow to the heart and cause chest pain, known as angina.
Angina is typically described as a squeezing, pressure, or heaviness in the chest. It can be triggered by physical exertion or emotional stress and is relieved with rest or medication.
Myocardial Infarction
A myocardial infarction, commonly known as a heart attack, occurs when the blood flow to a part of the heart is completely blocked, usually due to a blood clot. This leads to the death of the heart muscle in that area.
Chest pain during a heart attack is often intense and prolonged, with a feeling of tightness or crushing pressure in the chest. It may also radiate to the arms, jaw, back, or neck. Other accompanying symptoms may include shortness of breath, nausea, and sweating.
Pericarditis
Pericarditis is the inflammation of the pericardium, the sac-like membrane that surrounds and protects the heart. Chest pain due to pericarditis is typically sharp and stabbing, and it can worsen with deep breaths or when lying down.
The pain may also radiate to the left shoulder or neck. In addition to chest pain, individuals may experience fever, cough, and fatigue.
Aortic Dissection
An aortic dissection occurs when there is a tear in the inner lining of the aorta, the largest artery in the body. This condition can cause sudden, severe chest pain that is described as tearing or ripping in nature.
The pain may radiate to the back and is often associated with a decreased blood pressure, loss of consciousness, and weak pulses. Aortic dissection is a medical emergency that requires immediate attention.
Arrhythmias
Arrhythmias refer to abnormal heart rhythms that can cause a variety of symptoms, including chest pain. Some arrhythmias can lead to a rapid heartbeat, known as tachycardia, which may result in chest discomfort or palpitations.

Other arrhythmias can cause a slow heartbeat, known as bradycardia, which may manifest as chest pain, dizziness, or fainting episodes. Arrhythmias can be diagnosed through an electrocardiogram (ECG) and require appropriate management.
Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy (HCM) is a genetic condition characterized by the thickening of the heart muscle, making it harder for the heart to pump blood effectively.
Chest pain associated with HCM is often brought on by physical activity and is relieved by rest. Other symptoms may include shortness of breath, fatigue, and dizziness. HCM can be diagnosed through imaging tests, such as echocardiography, and managed with medication and lifestyle modifications.
Pulmonary Embolism
A pulmonary embolism occurs when a blood clot travels to the lungs, blocking one of the pulmonary arteries. This can lead to chest pain, especially with deep breaths, along with shortness of breath, rapid breathing, and a rapid heart rate.
Other symptoms can include coughing up blood and feeling lightheaded. Prompt medical intervention is crucial in the case of a pulmonary embolism.
Valvular Heart Disease
Valvular heart disease refers to conditions that affect the valves of the heart, hindering their proper functioning. Chest pain associated with valvular heart disease can occur due to narrowed or leaking valves that interfere with normal blood flow.
The pain may be exertional and may also be accompanied by shortness of breath, fatigue, and palpitations. Management of valvular heart disease often involves medication or surgical intervention, depending on the severity of the condition.
Angina Pectoris
Angina pectoris is a type of chest pain that occurs when there is an inadequate blood supply to the heart. It is often a symptom of underlying coronary artery disease.
The chest pain may manifest as a tightness, squeezing, or pressure, and it is typically provoked by physical activity or emotional stress. Rest and medication can help relieve angina symptoms, but it is important to address the underlying cause to prevent further complications.
Heartburn and GERD
Heartburn and gastroesophageal reflux disease (GERD) can cause chest pain that is often mistaken for a heart-related issue. The pain is often burning in nature and is typically felt in the lower chest or upper abdomen.
It is accompanied by a sour taste in the mouth, regurgitation of stomach acid, and a worsening of symptoms when lying down or bending over. Lifestyle modifications and medications can help manage heartburn and GERD.
