Chest pain is one of the most common reasons patients seek care at a cardiology clinic, and it can signal a serious heart condition. At Premier Cardiology, we provide thorough evaluation and treatment for angina, helping patients identify the root cause of their symptoms and prevent complications such as heart attack or heart failure. Understanding the nature of chest pain, its causes, and available treatments is critical for anyone experiencing cardiac discomfort.
What Is Angina?
Angina is not a disease itself but a symptom that occurs when the heart muscle does not receive enough oxygen-rich blood. Most commonly, angina is caused by coronary artery disease (CAD), where plaque buildup narrows the coronary arteries. This reduction in blood flow leads to chest pressure, squeezing, or discomfort. Angina can be triggered by physical activity, emotional stress, or other factors that increase the heart’s demand for oxygen.
Because angina signals a potential underlying heart problem, it should never be ignored. Early evaluation can prevent more serious events and help patients manage their condition effectively.
Types of Angina
There are several forms of angina, each with distinct characteristics:
- Stable Angina – Predictable discomfort that occurs with exertion or stress and typically improves with rest or medication.
- Unstable Angina – Unpredictable or worsening chest pain, often occurring at rest. This form is a medical emergency and may precede a heart attack.
- Variant (Prinzmetal’s) Angina – Caused by a temporary spasm in a coronary artery, often occurring at rest.
- Microvascular Angina – Involves the heart’s small vessels and can occur even without major arterial blockages.
Symptoms of Angina
Angina symptoms can vary from person to person but often include:
- Pressure, tightness, or squeezing in the chest
- Pain radiating to the jaw, neck, shoulder, or arms
- Shortness of breath
- Fatigue or lightheadedness
- Nausea or sweating
Symptoms that occur at rest, last longer than usual, or differ from prior episodes may indicate unstable angina, which requires immediate medical attention.
Causes and Risk Factors
The most common cause of angina is CAD, but other contributing factors include:
- High blood pressure (High Blood Pressure)
- High cholesterol (High Cholesterol)
- Diabetes
- Smoking
- Obesity (Obesity)
- Sedentary lifestyle
- Stress or anxiety
- Family history of heart disease
Addressing these risk factors is essential for preventing angina from worsening and reducing the risk of a heart attack.
Diagnosis
Accurate diagnosis involves evaluating heart function and blood flow. Premier Cardiology may recommend:
- EKG – Measures the heart’s electrical activity
- Stress Test – Assesses heart function during physical or pharmacologic stress
- Echocardiogram – Visualizes heart structure and motion
- CT Scan – Examines the coronary arteries for blockages
- Cardiac Catheterization / Angiogram – Directly measures arterial blockages
- Nuclear Stress Test – Evaluates blood flow to the heart muscle during stress
- MRI – Provides detailed images of the heart structure
Treatment Options
Treatment depends on severity and underlying causes:
Lifestyle Changes
- Heart-healthy diet rich in fruits, vegetables, and whole grains
- Regular physical activity
- Weight management
- Smoking cessation
- Stress reduction techniques
Medications
- Nitrates to relieve chest pain
- Beta-blockers to reduce heart workload
- Calcium channel blockers to relax coronary arteries
- Aspirin or other antiplatelet drugs to prevent clot formation
- Cholesterol-lowering medications
Interventional Procedures
For patients with significant arterial blockages or persistent symptoms, treatment may include:
- Angioplasty and Stenting
- Atherectomy
- Coronary Artery Bypass Graft (CABG)
When to Seek Emergency Care
Call 911 immediately if chest pain:
- Occurs at rest or is more severe than usual
- Lasts longer than a few minutes
- Is accompanied by shortness of breath, fainting, or excessive sweating
Prompt care can prevent heart attack and save lives.
