What Is Angina?

Angina is a symptom, often described as chest discomfort or pressure, that can occur when the heart muscle is not receiving enough oxygen-rich blood. It is linked to coronary artery disease, but it can also appear in other heart-related conditions. Angina may range from mild and brief to more persistent or severe; understanding what it is, what triggers it, and what it can signal is fundamental for early action and appropriate care. Here’s more information on what angina is:

Is Angina a Disease?

Angina is a physical indicator of an underlying issue, and it usually points to coronary artery disease. When the major blood vessels that supply your heart become damaged or diseased, plaque builds up within the artery walls. Plaque buildup forces the heart to work harder to pump blood. The narrowed arteries restrict blood flow, but the heart still demands a steady supply of oxygen to keep functioning. 

The heart muscle receives less blood than it needs during physical exertion; the resulting oxygen shortage produces the chest pain you feel. Understanding this distinction is fundamental to managing your heart health. You must address the root cause of reduced blood flow, or the symptom will recur. 

What Types of Angina Exist?

Healthcare providers categorize angina into different types based on the exact cause and the severity of the symptoms. Here are the types of angina:

• Stable angina occurs during physical activity when the heart pumps harder and follows a predictable pattern lasting for two or more months.
• Unstable angina is entirely unpredictable, causing sudden chest pain with or without physical exertion.
• Microvascular angina affects the tiny blood vessels in the heart, and it causes severe pain that lasts much longer than other forms.
• Variant angina is very rare and occurs when the muscles within the arteries suddenly contract, restricting blood flow.

Identifying the specific type of chest pain dictates the direction of your medical care.

What Causes Angina?

The primary cause of angina remains the buildup of fatty plaques in the coronary arteries. The buildup narrows the arteries significantly, and it reduces the amount of oxygen-rich blood that reaches the heart muscle. When you engage in physical activities, the heart demands more oxygen, but the narrowed arteries cannot deliver the required blood volume. Certain lifestyle choices and health conditions place specific individuals at a higher risk of developing this symptom. High blood pressure damages the arteries over time, and high cholesterol levels accelerate the accumulation of arterial plaque.

How Is It Diagnosed?

Medical professionals use a variety of tools to evaluate your heart health and identify the exact cause of your discomfort. Here are some of the tests they often recommend:

• Electrocardiograms measure the electrical activity of your heart to detect irregular rhythms or signs of previous damage.
• Echocardiograms use sound waves to produce images of the heart, allowing doctors to observe how well the heart pumps blood.
• Stress tests monitor your heart activity while you exercise on a treadmill to reveal how the heart responds to physical exertion.
• Lifestyle modifications act as the first line of treatment, but doctors also prescribe medications to relax blood vessels and improve blood flow.

Lifestyle modifications act as the first line of treatment, but doctors also prescribe medications to relax blood vessels and improve blood flow. If lifestyle changes and medications fail to relieve your symptoms, your doctor may recommend surgical procedures to open the blocked arteries.
