Angina at rest refers to a medical condition characterized by symptoms of angina, which is chest pain or discomfort, occurring even in a state of rest or minimal exertion. It is caused by reduced blood flow to the heart muscle due to the narrowing or blockage of the coronary arteries that supply oxygenated blood to the heart. Angina at rest is considered a more severe form of angina as it can occur without any triggers or physical activity, unlike stable angina that is typically induced by exercise or stress.
The symptoms of angina at rest may include a squeezing or pressure-like sensation in the chest, pain or discomfort that may radiate to the arms, shoulders, neck, jaw, or back. Other associated symptoms may include shortness of breath, nausea, dizziness, sweating, and fatigue. These symptoms tend to last longer than those of stable angina and may not subside with rest or nitroglycerin medication.
Angina at rest is a worrisome condition as it could be a sign of an impending heart attack or unstable angina. Prompt medical attention is necessary to prevent further complications. Diagnosis usually involves a medical history evaluation, including risk factors and an assessment of the frequency, intensity, and duration of symptoms. Additional diagnostic tests such as electrocardiogram (ECG/EKG), stress tests, and coronary angiography may be performed to evaluate the extent of the coronary artery disease and determine appropriate treatment options.
Treatment for angina at rest aims to relieve symptoms, improve blood flow to the heart, and reduce the risk of heart attack. Medications such as nitroglycerin, beta-blockers, calcium channel blockers, and aspirin may be prescribed. Lifestyle changes, including smoking cessation, exercise, healthy diet, and stress management, are also crucial components of
