QuestionAnswer
Coronary Artery Disease (CAD) conditions that obstruct blood flow in the coronary arteries
Stable Angina Pectoris Narrowed coronary arteries cause predictable chest pain or discomfort with exertion. The blockages prevent the heart from receiving the extra oxygen needed for strenuous activity. Symptoms typically get better with rest.
Unstable Angina Pectoris Chest pain or discomfort that is new, worsening, or occurs at rest. This is an emergency situation as it can precede a heart attack, serious abnormal heart rhythm, or cardiac arrest
Hyperlipidemia elevated concentraions of any or all lipids in the plasma
Arrhythmia (dysrhythmia) An abnormal heart rhythm due to changes in the conduction of electrical impulses through the heart. Some arrhythmias are benign, but others are life-threatening.
Congestive heart failure(CHF) The heart is either too weak or too stiff to effectively pump blood through the body. Shortness of breath and leg swelling are common symptoms.
Cardiomyopathy A disease of heart muscle in which the heart is abnormally enlarged, thickened, and/or stiffened. As a result, the heart's ability to pump blood is weakened
Pericarditis Inflammation of the lining of the heart (pericardium). Viral infections, kidney failure, and autoimmune conditions are common causes
Pericardial effusion Fluid between the lining of the heart (pericardium) and the heart itself. Often, this is due to pericarditis
Atrial fibrillation Abnormal electrical impulses in the atria cause an irregular heartbeat. Atrial fibrillation is one of the most common arrhythmias
Heart valve disease There are four heart valves, and each can develop problems. If severe, valve disease can cause congestive heart failure.
Heart murmur An abnormal sound heard when listening to the heart with a stethoscope. Some heart murmurs are benign; others suggest heart disease.
Endocarditis Inflammation of the inner lining or heart valves of the heart. Usually, endocarditis is due to a serious infection of the heart valves
Mitral valve prolapse The mitral valve is forced backward slightly after blood has passed through the valve
Sudden cardiac death Death caused by a sudden loss of heart function (cardiac arrest).
Cardiac arrest Sudden loss of heart function
Electrocardiogram (ECG or EKG) A tracing of the heart’s electrical activity. Electrocardiograms can help diagnose many heart conditions
Echocardiogram An ultrasound of the heart. An echocardiogram provides direct viewing of any problems with the heart muscle’s pumping ability and heart valves
Exercise stress test By using a treadmill or medicines, the heart is stimulated to pump to near-maximum capacity. This may identify people with coronary artery disease
Cardiac catheterization A catheter is inserted into the femoral artery in the groin and threaded into the coronary arteries. A doctor can then view X-ray images of the coronary arteries or any blockages and perform stenting or other procedures
Holter monitor If a doctor suspects an arrhythmia, a portable heart monitor can be worn. Called a Holter monitor, it records the heart's rhythm continuously for a 24 hour period
Event monitor If a doctor suspects an infrequent arrhythmia, a portable heart monitor called an event monitor can be worn. When you develop symptoms, you can push a button to record the heart's electrical rhythm
Exercise Regular exercise is important for heart health and most heart conditions. Talk to your doctor before starting an exercise program if you have heart problems
Angioplasty During cardiac catheterization, a doctor inflates a balloon inside a narrowed or blocked coronary artery to widen the artery. A stent is often then placed to keep the artery open
Percutaneous coronary intervention (PCI) Angioplasty is sometimes called a PCI or PTCA (percutaneous transluminal coronary angioplasty) by doctors.
Coronary artery stenting During cardiac catheterization, a doctor expands a wire metal stent inside a narrowed or blocked coronary artery to open up the area. This lets blood flow better and can abort a heart attack or relieve angina (chest pain)
Thrombolysis “Clot-busting” drugs injected into the veins can dissolve a blood clot causing a heart attack. Thrombolysis is generally only done if stenting is not possible
Lipid-lowering agents Statins and other cholesterol (lipid) lowering drugs reduce the risk for heart attack in high-risk people
Diuretics Commonly called water pills, diuretics increase urination and fluid loss. This reduces blood volume, improving symptoms of heart failure
Beta-blockers These medicines reduce strain on the heart and lower heart rate. Beta-blockers are prescribed for many heart conditions, including heart failure and arrhythmias.
ICD (Implantable cardioverter defibrillator) If a doctor suspects you are at risk for a life-threatening arrhythmia, an implantable cardioverter defibrillator may be surgically implanted to monitor your heart rhythm and send an electrical shock to the heart if necessary
Pacemaker To maintain a stable heart rate, a pacemaker can be implanted. A pacemaker sends electrical signals to the heart when necessary to help it beat properly.
Aneurysm a localized dilation of the wall of a blood vessel
Arteriosclerosis aterial disorder characterized by loss of elasticity, thickening, and calcification of the arterial walls, resulting in a decreased blood supply
Atherosclerosis arterial disorder characterized by yellowish plaques of cholesterol, lipids, and cellular debris in the inner layers of the walls of large and medium size arteries.
Defibrillation converting ventricular fibrillation by delivering a direct electrical countershock to the precordium
Dysrhythmia any cardiac rhythm that is not normal sinus rhythm. Also called arrhythmia
Embolus a foreign object, piece of tissue or tumor, air or gas, or a thrombus that travels in the circulatory system until it becomes lodged in a vessel
Heart Failure syndrome of circulatory congestion due to the hearts inability to act as an effective pump
Endarterectomy surgical removal of the intimal lining of an artery
Cardioversion restoration of the hearts normal sinus rhytm by delivery of a synchronized electric shock through two paddles placed on the patients chest
Hypoxemia an abnormal deficiency of oxygen in the arterial blood
Intermittent Claudication a weakness of the legs accompanied by cramp like pain in the calves caused by decreased arterial blood circulation to the leg muscles
Ischemia Decreased blood supply to a body organ or part, often marked by pain and organ dysfunction
Myocardial Infarction(MI) necrosis of a portion of the cardiac muscle caused by an occlusion of a major artery or one of its branches
Occlusion an obstruction or closing off in a canal, vessel, or passage of the body
Orthopnea patient must sit up or stand to breath deeply and comfortably
Peripheral pertaining to the outside, surface or surrounding area
Pleural Effusion an accumulation of fluid in the thoracic cavity between the visceral and parietal layers
Polycythemia an abnormal increase in the number of red blood cells in the blood
