Angina his chest pain or discomfort that presents from a lack of blood and oxygen flow to the heart muscle. A narrowed or blocked artery due coronary artery diseases the most common cause of angina. When blood cannot reach the heart tissue, especially during physical activity, chest discomfort may occur that can last up to several minutes. Angina may be treated with rest, medication, cardiac rehabilitation, and surgery.
Your heart has several large arteries and veins connected to it that branch out and become smaller as they travel throughout your body. Your arteries deliver blood from the heart and veinsreturn blood to the heart in the process called circulation.
The aorta is the largest blood vessel in your body.The aorta caries all the blood pumped out of your heart. Through its many branches, the aorta distributes blood to all of the areas and organs in your body. Two coronary arteries branch out from the aorta supplying the heart with oxygen, blood, and nutrients to keep it healthy.
The most common cause of angina is coronary artery disease caused by artherosclerosis, hardening of the arteries. Initially, plaque formation may narrow the arteries. Over time, the plaques may rupture to form a plug or clot that can block an artery.When an artery is narrowed or blocked, blood and oxygen cannot reach the heart muscle. This results in discomfort, especially upon exertion. Other less common causes of angina include a spasm of the artery, valvular heart disease, an enlarged heart, on uncontrolled height blood pressure.
Angina results when the heart does not get enough blood and oxygen. This may happen after you exercise or exert yourself, such as after climbing stairs, carrying in the groceries, or during sex. Angina may occur when you are emotionally upset, angered, or stressed. Having a full stomach or being in very hot or cold temperatures may also bring about angina.
Angina causes chest discomfort that typically lasts from about one minute to 5 minutes. The discomfort usually feels like pressure, heaviness, tightness, squeezing, burning, and pain. This may occur in the chest, back, neck, jaws, arms, stomach area, and shoulders. Your shoulders, arms, or wrists may feel numb or tingle. It may be difficult to breathe. You may sweat or feel nauseous.
Contact your Doctor if you experience angina. People with anginahave an increased risk for a heart attack, cardiac arrest, and sudden cardiac death. An ambulance should be called immediately if a heart attack is suspected. Symptoms of heart attack include new, worsening, or persistent pain or pressure in the center of the chest, shortness of breath, nausea, vomiting, and pain that radiates from the chest into the teeth, jaws, shoulders, or arms. A heart attack can be fatal. Immediate emergency medical care is necessary to sustain life and prevent complications.
Your Doctor can begin to diagnose angina after reviewing your medical history, performing an examination, and conducting some tests. There are different types of angina. You should tell your Doctor about your symptoms, medical history, and any family history of heart disease. Blood tests and other assessments will be done to determine how your heart is functioning. In some cases, blood tests predict the likelihood of the progression from angina to a heart attack.
Several tests are used to identify angina. Common tests include an electrocardiogram (ECG), exercise stress test, nuclear stress test, and coronary angiogram. An ECG records the heart's electrical activity. An ECG may be repeated over several hours. An exercise stress test, also called cardiac stress test or treadmill test, involves monitoring your ECG and blood pressure
