Q

infarct

in-FARKT

Study These Flashcards
A

An area of localized tissue necrosis (death) resulting from a blockage or a narrowing of the artery that supplies the area

18
ischemia is-KE-me-ah
Local deficiency of blood supply caused by circulatory obstruction
19
myocardial infarction (MI) mi-o-KAR-de-al in-FARK-shun
Localized necrosis (death) of cardiac muscle tissue resulting from blockage or narrowing of the coronary artery that supplies that area; myocardial infarction is usually caused by formation of a thrombus (clot) in a vessel
19
murmur
An abnormal heart sound
20
occlusion o-KLU-zhun
A closing off or obstruction, as of a vessel
21
patent ductus arteriosus PA-tent DUK-tus ar-tere-e-O-sus
Persistence of the ductus arteriosus after birth; the ductus arteriosus is a vessel that connects the pulmonary artery to the descending aorta in the fetus to bypass the lungs
22
phlebitis fleh-BI-tis
Inflammation of a vein
23
plaque Plak
A patch; with regard to the cardiovascular system, a deposit of fatty material and other substances on a vessel wall that impedes blood flow and may block the vessel; atheromatous plaque
24
rheumatic heart disease ru-MAT-ik
Damage to heart valves after infection with a type of Streptococcus (group A hemolytic Streptococcus); the antibodies produced in response to the infection produce valvular scarring usually involving the mitral valve
25
septal defect SEP-tal
An opening in the septum between the atria or ventricles; a common cause is persistence of the foramen ovale (for-A-men o-VAL-e), an opening between the atria that bypasses the lungs in fetal circulation
26
shock
Circulatory failure resulting in an inadequate blood supply to the tissues; cardiogenic shock is caused by heart failure; hypovolemic shock is caused by a loss of blood volume; septic shock is caused by bacterial infection
27
stenosis steh-NO-sis
Constriction or narrowing of an opening
27
stroke
See cerebrovascular accident
28
syncope SIN-ko-pe
A temporary loss of consciousness caused by inadequate blood flow to the brain; fainting
29
thrombophlebitis throm-bo-fleh-BI-tis
Inflammation of a vein associated with formation of a blood clot
29
tachycardia tak-ih-KAR-de-ah
An abnormally rapid heart rate, usually over 100 bpm
30
thrombosis throm-BO-sis
Development of a blood clot within a vessel
31
thrombus THROM-bus
A blood clot that forms within a blood vessel (root: thromb/o)
32
varicose vein VAR-ih-kose
A twisted and swollen vein resulting from breakdown of the valves, pooling of blood, and chronic dilatation of the vessel (root: varic/o); also called varix (VAR-iks) or varicosity (var-ih-KOS-ih-te)
33
ablation ab-LA-shun
Removal or destruction. In cardiac ablation, a catheter is used to destroy a portion of the heart’s conduction pathway to correct an arrhythmia
34
angioplasty AN-je-o-plas-te
A procedure that reopens a narrowed vessel and restores blood flow; commonly accomplished by surgically removing plaque, inflating a balloon within the vessel, or installing a device (stent) to keep the vessel open
35
artificial pacemaker
A battery-operated device that generates electrical impulses to regulate the heartbeat; it may be external or implanted, may be designed to respond to need, and may have the capacity to prevent tachycardia
35
cardiopulmonary resuscitation (CPR) kar-de-o-PUL-mo-nar-e re-sus-ih-TA-shun
Restoration of cardiac output and pulmonary ventilation after cardiac arrest using artificial respiration and chest compression or cardiac massage
36
cardioversion KAR-de-o-ver-zhun
Correction of an abnormal cardiac rhythm; may be accomplished pharmacologically, with antiarrhythmic drugs, or by application of electric current
36
coronary angiography KOR-o-na-re an-je-OG-rah-fe
Radiographic study of the coronary arteries after introduction of an opaque dye by means of a catheter threaded through blood vessels into the heart
37
coronary artery bypass graft (CABG)
Surgical creation of a shunt to bypass a blocked coronary artery; the aorta is connected to a point past the obstruction with another vessel or a piece of another vessel, usually the left internal mammary artery or part of the leg’s saphenous vein
38
coronary calcium scan
Method for visualizing vessel-narrowing calcium deposits in coronary arteries; useful for diagnosing coronary artery disease in people at moderate risk or those who have undiagnosed chest pain; also known as a heart scan
39
creatine kinase MB (CK-MB) KRE-ah-tin KI-naze
Enzyme released in increased amounts from cardiac muscle cells following myocardial infarction (MI); serum assays help diagnose MI and determine the extent of muscle damage
40
CT angiography (CTA) an-je-OG-rah-fe
Computed tomography scan used to visualize vessels in the heart and other organs; requires only a small amount of dye injected into the arm; can rule out blocked coronary arteries that may cause a myocardial infarction (heart attack) in people with chest pain or abnormal stress tests
41
echocardiography ek-o-kar-de-OG-rah-fe
A noninvasive method that uses ultrasound to visualize internal cardiac structures
41
defibrillation de-fib-rih-LA-shun
Use of an electronic device (defibrillator) to stop fibrillation by delivering a brief electric shock to the heart; the shock may be delivered to the surface of the chest, as by an automated external defibrillator (AED), or directly into the heart through wire leads, using an implantable cardioverter defibrillator (ICD)
42
lipoprotein lip-o-PRO-tene
A compound of protein with lipid; lipoproteins are classified according to density as very low-density (VLDL), low-density (LDL), and high-density (HDL); relatively higher levels of HDLs have been correlated with cardiovascular health
43
percutaneous transluminal coronary angioplasty (PTCA)
Dilatation of a sclerotic blood vessel by means of a balloon catheter inserted into the vessel and then inflated to flatten plaque against the arterial wall
44
stent
A small metal device in the shape of a coil or slotted tube that is placed inside an artery to keep the vessel open, for example, after balloon angioplasty
45
stress test
Evaluation of physical fitness by continuous ECG monitoring during exercise; in a thallium stress test, a radioactive isotope of thallium is administered to trace blood flow through the heart during exercise
46
troponin (Tn) tro-PO-nin
A protein in muscle cells that regulates contraction; increased serum levels, primarily in the forms TnT and TnI, indicate recent myocardial infarction (MI)
