Like any exclusive club, heart disease has its own jargon, understandable only by other members of the club, particularly by cardiac care providers.  For example, I remember lying in my CCU bed (that’s the Coronary Intensive Care Unit), trying to memorize the letters LAD (that’s the Left Anterior Descending, the large coronary artery whose 99% blockage had caused my MI (myocardial infarction – in my case, the so-called ‘widowmaker’ heart attack).

To help others needing simultaneous translation of this new lingo in your research or in your own medical records, here’s a helpful list of some of the most common acronyms/terms you’ll likely find around the cardiac ward.   

Tiesworks

AA – Anti-arrhythmic: Drugs used to treat patients who have irregular heart rhythms.

ABI – Ankle-Brachial Index: The ratio of the blood pressure in the lower legs to the blood pressure in the arms. Compared to the arm, lower blood pressure in the leg may be an indication of blocked arteries (See PAD or Peripheral Artery Disease)

AblationSee Cardiac Ablation.

ACE Inhibitor – Angiotension Converting Enzyme inhibitor: A drug that lowers blood pressure by interfering with the breakdown of a protein-like substance involved in regulating blood pressure.

ACS – Acute Coronary Syndrome:  An emergency condition brought on by sudden reduced blood flow to the heart. The first sign of acute coronary syndrome can be sudden stopping of your heart (cardiac arrest).

AED – Automatic External Defibrillator: A portable defibrillator for use during a cardiac emergency; it can be used on patients experiencing sudden cardiac arrest by applying a brief electroshock to the heart through electrodes placed on the chest.

AF or Afib – Atrial Fibrillation:  An irregular and often rapid heart rate that can cause poor blood flow to the body. Afib symptoms include heart palpitations, shortness of breath, weakness or fainting. Episodes of atrial fibrillation can come and go, or you may have chronic atrial fibrillation.

AFL – Atrial Flutter:  A type of arrhythmia where the upper chambers of the heart (the atria) beat very fast, causing the walls of the lower chambers (the ventricles) to beat inefficiently as well.

A-HCM –  Apical Hypertrophic Cardiomyopathy: Also called Yamaguchi Syndrome or Yamaguchi Hypertrophy, a non-obstructive form of cardiomyopathy (a disease of the heart muscle that leads to generalized deterioration of the muscle and its pumping ability) in which a portion of the heart muscle is hypertrophied (thickened) without any obvious cause although there may be a genetic link. It was first described in individuals of Japanese descent.

AI – Aortic Insufficiency:  A heart valve disease in which the aortic valve does not close tightly, leading to the backward flow of blood from the aorta (the largest blood vessel) into the left ventricle (a chamber of the heart).

AIVR – Accelerated Idioventricular Rhythm:  Ventricular rhythm whose rate is greater than 49 beats/min but less than 100 beats/min, usually benign. (Ventricles are the two main chambers of the heart, left and right).

AMI – Acute Myocardial Infarction:  See MI

Angioplasty –  An invasive but non-surgical technique for treating diseased arteries by temporarily inflating a tiny balloon inside an artery during an angiography procedure.  A tiny metal stent is almost always inserted during this procedure to help keep the artery opened. Also called Percutaneous Transluminal Coronary Angioplasty (PTCA) or Percutaneous Coronary Intervention (PCI).  See also: “10 Things I Didn’t Know About Angioplasty Until I Read This Book”

Angina (stable) –  A condition marked by distressing symptoms typically between neck and navel that come on with exertion and go away with rest, caused by an inadequate blood supply to the heart muscle typically because of narrowed coronary arteries feeding the heart muscle.  Also known as Angina Pectoris.  Unstable angina (UA) occurs when fatty deposits (plaques) in a blood vessel rupture or a blood clot forms, blocking or reducing flow through a narrowed artery, suddenly and severely decreasing blood flow to the heart muscle. Unstable angina is not relieved by rest; it’s dangerous and requires emergency medical attention.

Antiplatelet drugs – Medications that block the formation of blood clots by preventing the clumping of platelets (examples: Plavix, Effient, Brillinta, Ticlid, etc). Heart patients, especially those with implanted stents after PCI, are often prescribed dual antiplatelet therapy which includes one of these prescribed meds along with daily low-dose aspirin.

CV – Cardiovascular:   Pertaining to the heart and blood vessels that make up the circulatory system.

DBP – Diastolic blood pressure:  The lowest blood pressure measured in the arteries. It occurs when the heart muscle is relaxed between beats.

DCM – Dilated Cardiomyopathy:  A disease of the heart muscle, primarily affecting the heart’s main pumping chamber (left ventricle). The left ventricle becomes enlarged (dilated) and can’t pump blood to your body with as much force as a healthy heart can.

DDI – Drug-drug interaction: A situation in which a medication affects the activity of another medication when both are administered together.

DIL – Diltiazem:  A calcium channel blocker drug that acts as a vasodilator; used in the treatment of angina pectoris, hypertension, and supraventricular tachycardia.

Diuretic – A class of drugs used to lower blood pressure. Also known as “water pills”.

Dobutamine stress echocardiography: This is a form of a stress echocardiogram diagnostic test.  But instead of exercising on a treadmill or exercise bike to stress the heart, the stress is obtained by giving a drug that stimulates the heart and makes it “think” it’s exercising. The test is used to evaluate your heart and valve function if  you are unable to exercise. It is also used to determine how well your heart tolerates activity, and your likelihood of having coronary artery disease (blocked arteries), and it can evaluate the effectiveness of your cardiac treatment plan.  See also TTE and Stress Echocardiogram.

Dressler’s syndrome – Happens to a small number of people three to four weeks after a heart attack. The heart muscle that died during the attack sets the immune system in motion, calling on lymphocytes, one of the white blood cells, to infiltrate the coverings of the heart (pericardium) and the lungs (pleura). It also starts generating antibodies, which attack those two coverings. Chest pain (CP) is the predominant symptom; treated with anti-inflammatory drugs.

Dual Antiplatelet TherapyMedications that block the formation of blood clots by preventing the clumping of platelets (examples Plavix, Effient, Brillinta, Ticlid, etc.) are often prescribed along with aspirin as part of what’s known as dual antiplatelet therapy, especially to patients who have undergone PCI and stent implantation.

Endothelial dysfunction affects the ability of these cells to help dilate blood vessels, control inflammation or prevent blood clots. The endothelium is associated with most forms of cardiovascular disease, such as hypertension, coronary artery disease, chronic heart failure, peripheral vascular disease, diabetes, chronic kidney failure, and severe viral infections.

Enhanced External Counterpulsation – EECP is an FDA-approved non-invasive, non-drug treatment for angina. It works by promoting the development of collateral coronary arteries. The therapy is widely used in prominent heart clinics such as the Cleveland Clinic, Mayo Clinic and Johns Hopkins – especially for patients who are not good candidates for invasive procedures such as bypass surgery, angioplasty or stenting.

EP – Electrophysiologist:  A cardiologist who has additional training in diagnosing/treating heart rhythm disorders.

EPS – Electrophysiology Study:   A test that uses cardiac catheterization to study patients who have arrhythmias (abnormal hear rhythm).

EVH – Endoscopic Vessel Harvesting:  To create the bypass graft during CABG open heart surgery, a surgeon will remove or “harvest” healthy blood vessels from another part of the body, often from the patient’s leg or arm. This vessel becomes a graft, with one end attaching to a blood source above and the other end below the blocked area. See CABG.

Exercise stress test – An exercise test (walking/running on a treadmill or pedalling a stationary bike) to make your heart work harder and beat faster.  An EKG is recorded while you exercise to monitor any abnormal changes in your heart under stress, with or without the aid of drugs to enhance this assessment. See also: MIBI, Echocardiogram, Nuclear Stress Test.

The opening is called ductus arteriosus and is a normal part of a baby’s circulatory system before birth that usually closes shortly after birth. But when it remains open, it’s called a patent ductus arteriosus. If it’s small, it may never need treatment, but a large PDA left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure or other complications.

Pericardium: the outer covering sac of the heart

PET – Positron Emission Tomography:  A non-invasive scanning technique that uses small amounts of radioactive positrons (positively charged particles) to visualize body function and metabolism. In cardiology, PET scans are used to evaluate heart muscle function in patients with coronary artery disease or cardiomyopathy.

PFO – Patent Forman Ovale:  An opening between the left and right atria (the upper chambers) of the heart. Everyone has a PFO before birth, but in 1 out of every 3 or 4 people, the opening does not close naturally as it should after birth.

Plaque – A deposit of fatty (and other) substances in the inner lining of the artery wall; it is characteristic of atherosclerosis.

PLOS – postoperative length of stay in hospital (see also LOS: length of stay)

POTS – Postural Orthostatic Tachycardia Syndrome:  A disorder that causes an increased heart rate when a person stands upright.

PPCM – Post-partum cardiomyopathyA form of cardiomyopathy that causes heart failure toward the end of pregnancy or in the months after delivery, in the absence of any other cause of heart failure.

Preeclampsia – a late-pregnancy complication identified by spikes in blood pressure, protein in the urine, possible vision problems. Women who experience pregnancy complications like preeclampsia are at significantly higher risk for heart disease. 

Prinzmetal’s Variant Angina – Chest pain caused by a spasm in a coronary artery that supplies blood to the heart muscle.

PRN“As needed” – from the Latin “pro re nata” meaning “as the circumstance arises” (used when medications are being prescribed to patients, not at specified times, but only when you need them)

PSVT – Paroxysmal Supraventricular Tachycardia:  – An occasional rapid heart rate (150-250 beats per minute) that is caused by events triggered in areas above the heart’s lower chambers (the ventricles). “Paroxysmal” means from time to time. See also supraventricular tachycardia (SVT).

PTCA – Percutaneous Transluminal Coronary Angioplasty:  See Angioplasty

Pulmonary Valve: One of the four valves in the heart, located between the pulmonary artery and the right ventricle of the heart, moves blood toward the lungs and keeps it from sloshing back into the heart.

PV – Pulmonary Vein:  A vein carrying oxygenated blood from the lungs to the left atrium of the heart.

PVC – Premature Ventricular Contraction:  An early or extra heartbeat that happens when the heart’s lower chambers (the ventricles) contract too soon, out of sequence with the normal heartbeat. In the absence of any underlying heart disease, PVCs do not generally indicate a problem with electrical stability, and are usually benign.

QD – Every day

QID – Four times a day

RA – Right Atrium:  The right upper chamber of the heart. The right atrium receives de-oxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.

Radial Artery: the artery in the wrist where a thin catheter is inserted through the body’s network of arteries in the arm and eventually into the heart during a procedure to implant a stent. Doctors may also call this transradial access, the transradial approach, or transradial angioplasty.  Because it’s associated with fewer complications, this is increasingly considered the default access approach in many countries, except in the U.S. where the traditional Femoral Artery (groin) approach is still used.

RBBB – Right Bundle Branch Block:  A delay or obstruction along the pathway that electrical impulses travel to make your heart beat. The delay or blockage occurs on the pathway that sends electrical impulses to the right side of your heart.  See also Left Bundle Branch Block.

RCA – Right Coronary Artery: An artery that supplies blood to the right side of the heart.

Restenosis –  The re-closing or re-narrowing of an artery after an interventional procedure such as angioplasty or stent placement. Sometimes called “stent failure”.

RHD – Rheumatic Heart Disease: Permanent damage to the valves of the heart caused especially by repeated attacks of rheumatic fever.

RM – Right Main coronary artery:  A blood vessel that supplies oxygenated blood to the walls of the heart’s ventricles and the right atrium.

RV – Right Ventricle:  The lower right chamber of the heart that receives de-oxygenated blood from the right atrium and pumps it under low pressure into the lungs via the pulmonary artery.

SA – Sinus node:  The “natural” pacemaker of the heart. The node is a group of specialized cells in the top of the right atrium which produces the electrical impulses that travel down to eventually reach the ventricular muscle, causing the heart to contract.

SB – Sinus Bradycardia:  Abnormally slow heartbeat.

SBP – Systolic Blood Pressure:  The highest blood pressure measured in the arteries. It occurs when the heart contracts with each heartbeat. Example: the first number in 120/80.

SCAD – Spontaneous Coronary Artery Dissection: A rare emergency condition that occurs when a tear forms in one of the blood vessels in the heart, causing a heart attack, abnormalities in heart rhythm and/or  sudden death. SCAD tends to strike young healthy women with few if any cardiac risk factors.

SCD – Sudden Cardiac Death:  Death as a result of Cardiac Arrest

SD – Septal defect: A hole in the wall of the heart separating the atria (two upper chambers of the heart) or in the wall of the heart separating the ventricles (two lower chambers).

Sestamibi stress test – See MIBI.

Short QT intervals (SQT):  An abnormal heart rhythm where the heart muscle takes a shorter time to recharge between beats. It can cause a variety of complications from fainting and dizziness to sudden cardiac arrest.

Sinoatrial node:  also commonly called the sinus node; it’s a small bundle of neurons situated in the upper part of the wall of the right atrium (the right upper chamber of the heart). The heart’s electrical impulses are generated there. It’s the normal natural pacemaker of the heart and is responsible for the initiation of the heartbeat.

SOB – Shortness of breath

Spontaneous Coronary Artery Dissection (SCAD) – A rare emergency condition that occurs when a tear forms in one of the blood vessels in the heart, causing a heart attack, abnormalities in heart rhythm and/or  sudden death. SCAD tends to strike young healthy women with few if any cardiac risk factors.

Small Vessel Disease –  See Microvascular Disease

Spasm – see Vasospasm.

SQT – see Short QT intervals

SSS – Sick Sinus Syndrome: The failure of the sinus node to regulate the heart’s rhythm.

ST – Sinus Tachycardia: A heart rhythm with elevated rate of impulses originating from the sinoatrial node, defined as greater than 100 beats per minute (bpm) in an average adult. The normal heart rate in the average adult ranges from 60–100 bpm.  Also called sinus tach or sinus tachy.

Statins –  Any of a class of drugs that lower the levels of low-density lipoproteins (LDL) – the ‘bad’ cholesterol in the blood – by inhibiting the activity of an enzyme involved in the production of cholesterol in the liver. Examples of brand name statins: Lipitor, Crestor, Zocor, Mevacor, Levachol, Lescol, etc.)

STEMI – ST-segment-elevation heart attack (myocardial infarction). The more severe form of the two main types of heart attack.  A STEMI produces a characteristic elevation in the ST segment on an electrocardiogram (EKG). The elevated ST segment is how this type of heart attack got its name. See also NSTEMI.

Stenosis – a narrowing of a passage in the body. See Aortic Stenosis

Stent – An implantable device made of expandable, metal mesh (looks a bit like a tiny chicken wire tube) that is placed (by using a balloon catheter) at the site of a narrowing coronary artery during an angioplasty procedure. The stent is then expanded and left in place to keep the artery open. TRIVIA ALERT:  the coronary stent was named after Charles Stent (1807-1885), an English dentist who invented a compound to produce dentures and other things like skin grafts and hollow tubes (essentially what a metal coronary stent is).  His real claim to fame occurred when he suggested using his material to coat underwater trans-Atlantic cable, which had broken several times as a result of corrosion by seawater. You’re welcome.

Stint – a common spelling mistake when what you really mean is the word “stent” (see above).

Stress test – A diagnostic test meant to assess the effects of exercise on the heart’s ability to function. See also: Nuclear Stress Test, MIBI, Exercise Stress Test, Stress Echocardiogram,

Stress Echocardiography – A standard echocardiogram test that’s performed while the person exercises on a treadmill or stationary bicycle. This test can be used to visualize the motion of the heart’s walls and pumping action when the heart is stressed, possibly revealing a lack of blood flow that isn’t always apparent on other heart tests. The echocardiogram is performed just before and just after the exercise part of the procedure. See also TTE.

Sudden Cardiac Arrest – The stopping of the heartbeat, usually because of interference with the electrical signal (often associated with coronary heart disease). Can lead to Sudden Cardiac Death.

Superior Vena Cava – large vein carrying blood from the head, arms, and upper body to the right atrium of the heart. Sometimes called precava.  See also Inferior Vena Cava

SVT – Supraventricular Tachycardia:  An occasional rapid heart rate (150-250 beats per minute) that is caused by events triggered in areas above the heart’s lower chambers (the ventricles);  see also paroxysmal supraventricular tachycardia (PSVT).  Also: Sustained Ventricular Tachycardia

Takotsubo Cardiomyopathy – A heart condition that can mimic a heart attack. Sometimes called Broken Heart Syndrome, it is not a heart attack, but it feels just like one, with common symptoms like severe chest pain and shortness of breath. It often follows a severe emotional stress. Prognosis is usually good, and recurrence occurs in fewer than 10% of patients.  Also referred to as Broken Heart Syndrome, stress cardiomyopathy, stress-induced cardiomyopathy or apical ballooning syndrome.

Tamponade – see Cardiac Tamponade

TAVI – Transcatheter aortic valve implantation: A minimally invasive procedure to repair a damaged or diseased aortic valve. A catheter is inserted into an artery in the groin and threaded to the heart. A balloon at the end of the catheter, with a replacement valve folded around it, delivers the new valve to take the place of the old. Also called TAVR (Transcatheter aortic valve replacement).

Tetralogy of Fallot – A rare condition caused by a combination of four heart defects that are present at birth, affecting the structure of the heart and causing oxygen-poor blood to flow out of the heart and into the rest of the body. Infants and children with Tetralogy of Fallot usually have blue-tinged skin because their blood doesn’t carry enough oxygen. Often diagnosed in infancy, but sometimes not until later in life depending on severity.

Tg – Triglycerides: The most common fatty substance found in the blood; normally stored as an energy source in fat tissue. High triglyceride levels may thicken the blood and make a person more susceptible to clot formation. High triglyceride levels tend to accompany high cholesterol levels and other risk factors for heart disease, such as obesity.

Thallium Stress Test –  See Nuclear Stress Test

TIA – Transient Ischemic Attack:  A stroke-like event that lasts only for a short time and is caused by a temporarily blocked blood vessel.

TID – Three times a day

TEE – Transesophageal echocardiogram: This test involves an ultrasound transducer inserted down the throat into the esophagus in order to take clear images of the heart structures without the interference of the lungs and chest.

Treadmill Stress Test –  See Exercise Stress Test.

Tricuspid Valve – One of four valves in the heart, a valve with three little flaps that keeps blood in the right ventricle from flowing back into the right atrium.  See also Valves

troponin –  a type of cardiac enzyme found in heart muscle, and released into the blood when there is damage to the heart (for example, during a heart attack). A positive blood test that shows elevated troponin is the preferred test for a suspected heart attack because it is more specific for heart injury than other blood tests.

TTE – Transthoracic Echocardiogram:  This is the standard echocardiogram, a painless test similar to X-ray, but without the radiation, using a hand-held device called a transducer placed on the chest to transmit high frequency sound waves (ultrasound). These sound waves bounce off the heart structures, producing images and sounds that can be used by the doctor to detect heart damage and disease.

TV – Tricuspid Valve:  One of four one-way valves in the heart, a structure that controls blood flow from the heart’s upper right chamber (the right atrium) into the lower right chamber (the right ventricle).

UA or USA – Unstable Angina: Chest pain that occurs when diseased blood vessels restrict blood flow to the heart; symptoms are not relieved by rest; considered a dangerous and emergency crisis requiring immediate medical help.

Valves:  Your heart has four one-way valves that keep blood flowing in the right direction. Blood enters the heart first through the tricuspid valve, and next goes through the pulmonary valve (sometimes called the pulmonic valve) on its way to the lungs. Then the blood returning from the lungs passes through the mitral (bicuspid) valve and leaves the heart through the aortic valve.  See diagram below.

Vasodilator:  A drug that causes dilation (widening) of blood vessels.

Vasospasm:  A blood vessel spasm that causes sudden constriction, reducing its diameter and blood flow to the heart muscle.  See also Prinzmetal’s Variant Angina.

VB – Ventricular Bigeminy:  A heart rhythm condition in which the heart experiences two beats of the pulse in rapid succession.

Vena Cava – a large vein that carryies de-oxygenated blood into the heart. There are two in humans, the inferior vena cava (carrying blood from the lower body) and the superior vena cava (carrying blood from the head, arms, and upper body).

Ventricle – each of the two main chambers of the heart, left and right.

VF – Ventricular Fibrillation:  A condition in which the ventricles (two lower chambers of the heart) contract in a rapid, unsynchronized fashion. When fibrillation occurs, the ventricles cannot pump blood throughout the body. Most sudden cardiac deaths are caused by VF or ventricular tachycardia (VT).

VLDL – Very Low Density Lipoprotein: Molecules made up of mostly triglycerides, cholesterol and proteins. VLDL, also known as the “very bad” cholesterol, carries cholesterol from the liver to organs and tissues in the body. It may lead to low density lipoproteins (LDL), associated with higher heart disease risks. VLDL levels are tricky to measure routinely, and are usually estimated as a percentage of your triglyceride levels. By reducing triglycerides, you are usually also reducing your VLDL levels.

VT or VTach – Ventricular Tachycardia:  An arrhythmia (abnormal heartbeat) in the ventricle usually seen as a very fast heartbeat. Most sudden cardiac deaths are caused by ventricular tachycardia (VT) or ventricular fibrillation (VF)

Warfarin – A drug taken to prevent the blood from clotting and to treat blood clots. Warfarin is believed to reduce the risk of blood clots causing strokes or heart attacks.  Also known as Coumadin.

Widowmaker heart attack – The type of heart attack I survived, since you asked. A nickname doctors use to describe a severely blocked left main coronary artery or proximal left anterior descending coronary artery of the heart. This term is used because if the artery gets abruptly and completely blocked, it can cause a massive heart attack that will likely lead to sudden cardiac deathPlease note the gender imbalance here: despite the number of women like me who do experience this type of cardiac event, doctors aren’t calling this the widowermaker, after all.

WPW – Wolff-Parkinson-White Syndrome: A condition in which an extra electrical pathway connects the atria (two upper chambers) and the ventricles (two lower chambers). It may cause a rapid heartbeat.

Yamaguchi Syndrome, Yamaguchi Hypertrophy – see A-HCM

    Maybe I missed it in your glossary, and I don’t have an abbreviation for it – my claim to fame is from a successful open heart surgery due to an Atrial Myxoma. I’m here to tell you that it almost took my life…

    Getting it diagnosed was quite a challenge. However, there were doctors willing to listen to me — especially since I was a young woman at the time 47yrs old. It’s twenty plus years later – and I rarely hear about the people who have or survived having one. 🙂

    Love this blog!

    My family doctor had me wear a 24 hr EKG. After reading the results, she has scheduled a scope to look inside my heart by a specialist. Completely forgoing a stress test. Said I have major changes in the EKG, what type of changes could they be looking at? Had LAD STENT INSERTED 7 YRS AGO – WHAT COULD THEY BE LOOKING FOR?

      Hi Kenneth – I’m not a physician so of course cannot comment on your specific case except to say that a stress test is generally useful to see if exercise can show up anything on the EKG when the heart is under stress from physical exertion. But if your 24 hr EKG is already showing something, there’s likely no need for a stress test. You need to directly ask your family doctor these same questions about your specific case, starting with the very basic: “What are all the possible things you’ll be looking for?” Take some notes during this appointment, and don’t be afraid to stop and ask her to clarify any answer you’re not completely sure about. Good luck to you…

      Thanks and welcome! I was thinking of editing that SCAD definition actually: I suspect that that it isn’t so much that SCAD is “rare”, but it’s more that it’s “rarely correctly diagnosed”.

        I totally agree that SCAD is not as rare as I believed for many years. Once awareness is spread to all medical staff, I believe many lives will be saved. Hoping for a brighter future for all SCAD patients.

          I hope so too, Cathy. Perhaps when more SCAD studies (like Mayo Clinic’s) are published and read by more and more MDs, it will no longer be “rarely correctly diagnosed”.

      Thanks so much, Ashley. I recently updated my original 2011 list after the world-famous Cleveland Clinic tweeted their glossary recently and I noticed that their list had a few glaring omissions (like SCAD and Brugada Syndrome) so this made me wonder what my list might be missing, too. Let me know if there’s anything else you think should be included, okay?
