You may experience symptoms of unstable angina after previously having symptoms of stable angina. Stable angina or typical angina pectoris is the most common form of angina. Unlike stable angina, unstable angina can occur without physical exertion and is not relieved by rest or medicine. Stable or silent angina is the most common form of angina in the elderly, and it occurs in an identifiable pattern. There are several different types of angina characterized by the timing and duration of symptoms. Stable angina is the most common form of angina and typically occurs with exertion and goes away with rest.
Unstable angina is considered to be an acute coronary syndrome in which there is no release of the enzymes and biomarkers of myocardial necrosis. The biomarkers of necrosis are below the threshold of myocardial infarction. During unstable angina, no enzymes and bio markers of myocardial necrosis are released during unstable angina thereby making it to be an acute coronary syndrome. Several symptoms can help you discern the presence of unstable angina. There is insufficient population-based data describing the prevalence of acute myocardial infarction in sub-Saharan Africa. There is a form of angina called cardiac syndrome X.
Angina is due to a temporary reduction in the flow of blood to part of the heart muscle and does not damage the heart itself. A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. Because of the decreased flow of blood, there is not enough oxygen to the heart muscle resulting in chest pain. Angina can be caused by an insufficient supply of blood and oxygen to the heart muscle. The pain is a result of an area of muscle surrounding the heart that is not receiving enough oxygen. The pain is caused by inadequate blood supply to your heart, which leaves your heart deprived of oxygen.
A heart attack is a prolonged decrease in oxygen to the heart that results in permanent damage to the heart. Certain heart enzymes slowly leak out into your blood if your heart has been damaged by a heart attack. An attack of angina does not cause permanent damage to the heart muscle. When certain ECG findings are present, the risk of unstable angina progressing to a heart attack is significantly increased. Where a heart attack threatens to lead to permanent damage to your heart muscle an angina attack is not. People with untreated unstable angina are at high risk of a heart attack or death.
Chest pain is the most common symptom of angina and is often described as a feeling of tightness or as a heavy weight on the chest. The classic chest pain from angina feels like significant pressure, squeezing, or tightness in the center of your chest. The chest pain associated with angina pectoris is described as squeezing, pressing, burning, choking, or bursting felt along the sternum. The pain may feel like tightness, heavy pressure, squeezing, or crushing pain. Angina presents itself more as a chest discomfort, rather than frank pain, which is described as pressure, heaviness, tightness, squeezing, burning, or choking sensation. Because of the seriousness of the disorder, anytime someone has pain in the chest, it is ascribed to angina.
Atherosclerosis is the buildup of fatty material called plaque along the walls of the arteries. Angina occurs when one or more of the coronary arteries become narrowed or blocked. Resting angina may occur as a result of plaque buildup in the arteries causing a coronary spasm. The coronary arteries can become narrowed by a gradual build-up of fatty material within their walls. Variant angina occurs when there is a narrowing of the artery due to a spasm. The balloon is inflated and deflated, pressing against the plaque buildup on the walls of the coronary artery and increasing the diameter of the artery.
Angina is one of the symptoms of coronary artery disease. Recent research has linked periodontal disease with the risk of coronary artery disease and stroke. One of the most characteristic and troubling features of coronary disease is the sudden and unexpected onset of symptoms in clinically stable patients and sometimes in even previously healthy individuals. Patients with rapid progression of atherosclerotic disease at multiple sites experience unstable angina more frequently. The angina symptoms are a result of coronary heart disease. Because heart disease is often the cause of most forms of angina, you can reduce or prevent angina by working on reducing your heart disease risk factors.
