What is the main cause of angina?

Angina is caused by reduced blood flow to your heart muscle. Your blood carries oxygen, which your heart muscle needs to survive. When your heart muscle isn’t getting enough oxygen, it causes a condition called ischemia. The most common cause of reduced blood flow to your heart muscle is coronary artery disease (CAD).

What are the two types of angina?

There are 2 main types of angina you can be diagnosed with:

• stable angina (more common) – attacks have a trigger (such as stress or exercise) and stop within a few minutes of resting.
• unstable angina (more serious) – attacks are more unpredictable (they may not have a trigger) and can continue despite resting.

What are the four E’s of angina?

In fact, exercise is one of what doctors call the four E’s of angina. The others are eating, emotional stress and exposure to cold. All increase the heart’s workload. In healthy people, the coronary blood vessels respond, supplying the heart with extra fuel in the form of oxygen.

What causes angina at night?

Angina decubitus is angina that occurs when a person is lying down (not necessarily only at night) without any apparent cause. Angina decubitus occurs because gravity redistributes fluids in the body. This redistribution makes the heart work harder.

Does an ECG show angina?

Diagnosing angina Your doctor can suspect a diagnosis of angina based on your description of your symptoms, when they appear and your risk factors for coronary artery disease. Your doctor will likely first do an electrocardiogram (ECG) to help determine what additional testing is needed to confirm the diagnosis.

When does angina start?

A young person can develop angina in their 20s or 30s, but it is quite rare. Angina comes about due to a reduction of blood flow being able to get to muscles in the heart. Typically, such a reduction naturally occurs because of age.

What is stress angina?

Stable angina is chest pain or discomfort that most often occurs with activity or emotional stress. Angina is due to poor blood flow through the blood vessels in the heart.

What foods are good for angina?

Eat plenty of fruits, vegetables, and whole grains. Choose lean proteins, such as skinless chicken, fish, and beans. Eat non-fat or low-fat dairy products, such as skim milk and low-fat yogurt. Avoid foods that contain high levels of sodium (salt).

What are the signs and symptoms of angina?

The symptoms of angina include mild or severe pain, pressure, or discomfort in the chest, the pain is generally described as a feeling of a squeezing, strangling, heaviness, or suffocation sensation in the chest.

What is the cause of 7.7 Prinzmetal’s angina?

7. 7 Prinzmetal’s Angina – Prinzmetal’s or variant angina is caused by a vasospasm, a spasm that narrows the coronary artery and lessens the blood flow to the heart.

Which is better for angina verapamil or nifedipine?

• The diphenylalkylamine verapamil slows cardiac atrioventricular (AV) conduction directly, and decreases heart rate, contractility, blood pressure, and oxygen demand. • Verapamil causes greater negative inotropic effects than nifedipine, but it is a weaker vasodilator.
