The health condition or disorder (& which body system)
A condition that occurs when there is insufficient blood flow and oxygen to the muscle of the heart. Angina can commonly occur due to the narrowing of coronary arteries.Angina itself is not a disease but is a symptom of an underlying heart problem.Angina frequently occurs during exertion, severe emotional stress, or after a heavy meal. This happens because the heart requires more oxygen than the narrowed arteries can provide it.
Angina Occurs in the cardiac system.
Oxygen is normally delivered to the heart by larger vessels such as arteries and arterioles, which branch out into capillaries. In a healthy, normal functioning heart there is little resistance to blood flow within these vessels to the heart. If there is any plaque present within the arteries this blocks them and causes resistance with blood flow. A person will experience chest pains as the pressure from the blood increases but can’t easily flow.
Signs and symptoms
Angina attacks can be prompted by exertion or physical exercise, when the hard-working heart muscle requires greater amounts of oxygen. The pain usually fades away with rest.
pain or discomfort in the middle of the chest
breathlessness and sweating
pressure or a feeling of tightness in the chest
radiating pain to the neck, jaw and left arm, or both arms sometimes, radiating pain in the upper back and shoulders.
Other signs and symptoms may include: nausea and fatigue
List of symptoms
Pain and discomfort are the main symptoms of angina and is described as pressure, squeezing, burning, or tightness in the chest. The pain may feel like indigestion. Some people say that angina pain is hard to describe or they can't tell exactly where the pain is coming from.
ECG An ECG is a simple, painless test that detects and records the heart’s electrical activity. An ECG also records the strength and timing of electrical signals as they pass through each part of the heart. However, some people who have angina have a normal ECG. Stress testing During stress testing, you exercise (or are given medicine if you’re unable to exercise) to make your heart work hard and beat fast while heart tests are done. As part of some stress tests, pictures are taken of your heart while you exercise and while you rest. These imaging stress tests can show how well blood is flowing in various parts of your heart and/or how well your heart squeezes out blood when it beats.
Chest X-ray A chest X-ray takes pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels. A chest X-ray can reveal signs of heart failure. However, a chest X-ray alone is not enough to diagnose angina or CHD.
Blood tests Blood tests check the levels of certain fats, cholesterol, sugar, and proteins in your blood. Abnormal levels may show that you have risk factors for CHD. Your doctor may recommend a blood test to check the level of a protein called C-reactive protein (CRP) in your blood. Some studies suggest that high levels of CRP in the blood may increase the risk of CHD and heart attack.
medications medical procedures
The main goals of treatment are to: reduce the pain and discomfort of angina and how often it occurs. Lower the risk of heart attack and death by treating the underlying heart condition.
Nurses should assess patients vital signs, position them correctly in bed, conduct pain assessments, record patient's heart rhythm for any abnormalities.
Blood tests should be conducted to record any troponin levels; which is released by heart if it is damaged. A stress test may also be used to record the heart while under pressure to view it's performance.
