Why Does Chest Pain (Angina) Occur? Causes and Current Treatment Options

Chest pain is one of the most common symptoms people experience, and it can have many different causes. When it originates from the heart, it is known as angina — pain or pressure that occurs when the heart muscle does not receive enough blood and oxygen, usually due to narrowed or blocked coronary arteries.

Recognizing the Types of Angina

Stable Angina

Occurs predictably during physical exertion or stress and typically resolves with rest.

Unstable Angina

Can occur unexpectedly, even at rest, and requires urgent medical evaluation.

Variant (Prinzmetal) Angina

Caused by temporary spasm of a coronary artery, often occurring at rest or during the night.

Refractory Angina

Chronic chest pain that persists despite medication and standard interventional treatments.

How EECP Can Help with Refractory Angina

Reduces Frequency & Severity

Many patients report fewer and milder angina episodes after completing a course of EECP.

Non-Surgical

A non-invasive outpatient option for patients who cannot or prefer not to undergo further intervention.

Improves Collateral Circulation

Encourages the heart to develop natural bypass pathways around narrowed arteries over time.

Improves Exercise Tolerance

Helps many patients return to daily activities with less chest discomfort.

Who Should Consider EECP for Angina

Persistent Symptoms

Angina that continues despite optimal medication.

Not a Candidate for Further Intervention

Patients for whom angioplasty or bypass surgery is not suitable or has already been performed.

Seeking a Non-Surgical Option

Patients who want to explore evidence-based options before considering more invasive procedures.

Important: Chest pain that starts suddenly, does not resolve with rest, and is accompanied by shortness of breath, sweating, or nausea may be a medical emergency — seek emergency medical care without delay.
