Blood clots are clumps that occur when blood hardens from a liquid to a solid.
A blood clot that forms inside a blood vessel or within the heart and stays there is called a thrombus. A thrombus that breaks loose and travels from one location in the body to another is called an embolus. The related medical disorder is called an embolism. For example, an embolus that gets stuck in the lungs is called a pulmonary embolism.
Sometimes other materials can act like an embolus and block blood flow, including:
A piece of atherosclerotic plaque
Small pieces of tumor
Atheroembolic renal disease
Deep venous thrombosis
Renal vein thrombosis
Treatment Lifestyle changes (such as dieting, exercising, and quitting smoking) are the first approach for all degrees of coronary artery disease. Depending on severity and individual conditions, patients may also need one or more medications, surgery, or both. Medications . Many types of medications are used to treat angina and CAD. They include: Anti-platelet and anticoagulant drugs (used for preventing heart disease and preventing blood clots prior to surgery or after stent insertion) Beta blockers ACE inhibitors Nitrates Calcium channel blockers Interventional Procedures and Surgery . Intervention is usually recommended for people who have: Unstable angina that does not respond promptly to medical treatment Severe recurrent episodes of angina that last more than 20 minutes Acute coronary syndrome Severe coronary artery disease (severe angina, multi-artery involvement, evidence of ischemia, or significant narrowing of left main coronary artery), particularly if abnormalities are evident in the l...
How It Happens The heart pumps blood enriched with oxygen and vital nutrients throughout the entire body by way of a network of arteries. The heart itself must also be supplied with oxygen-rich blood in order to perform its job. Heart disease occurs when blood flow to the heart is blocked due to fatty material building up in the arteries and eventually closing them off. This process is called atherosclerosis , or “hardening of the arteries.” The fatty buildup can eventually close the arteries off, or, if the fatty deposit breaks, a blot clot can form, which can also block the flow of oxygenated blood to the heart. As a result, the heart becomes badly damaged due to tissue death from lack of oxygen. Common Symptoms Chest Pain Cold sweats, shortness of breath and lightheadedness Heart attack Coronary heart disease commonly leads to heart attack. If you believe you are experiencing a heart attack, call 911 or contact your emergency response system immediately. Learn more about heart a...
