Treatment for Unstable Angina First, your healthcare provider will need to find the blocked part or parts of the coronary arteries by performing a cardiac catheterization. acute coronary syndrome, a classification encompassing clinical presentations ranging from unstable angina through myocardial infarctions not characterized by alterations in Q waves. The classification sometimes also includes myocardial infarctions characterized by altered Q waves. Causes of Unstable Angina: Blood clots that block an artery partially or totally are what causes unstable angina. Blood clots may form, partially dissolve, and later form again and angina can occur each time a clot blocks blood flow in an artery. Call 911 or other emergency services immediately if you have symptoms of acute coronary syndrome.

He or she will guide a catheter through an artery in the arm or leg and into the coronary arteries, then inject a liquid dye through the catheter. The most common cause is reduced blood flow to the heart muscle because the coronary arteries are narrowed by fatty buildups (atherosclerosis) which can rupture causing injury to the coronary blood vessel resulting in blood clotting which blocks the flow of blood to the heart muscle. Acute coronary syndrome happens because blood flow has slowed or stopped in the arteries that supply blood to the heart. Acute coronary syndrome is typically caused by coronary artery disease. Coronary artery disease, also called heart disease, is caused by atherosclerosis, or hardening of the arteries. Atherosclerosis causes a substance called plaque to build up in the coronary arteries. Unstable angina or sometimes referred to as acute coronary syndrome causes unexpected chest pain, and usually occurs while resting. acute respiratory distress syndrome (ARDS) a group of symptoms accompanying fulminant pulmonary edema and resulting in acute respiratory failure; called also shock lung, wet lung, and many other names descriptive of etiology or clinical manifestations.
