Angina Pectoris

A

Chest pain that occurs when diseased blood vessels restrict blood flow to the heart. It is the most common symptom of coronary artery disease (CAD) and is often referred to as angina. The pain can radiate to the neck, jaw, or left arm. It is often described as a crushing, burning, or squeezing sensation.

Automated External Defibrillator (AED)

A

Portable automatic device used to restore normal heart rhythm to patients in cardiac arrest. An AED is applied outside the body. It automatically analyzes the patient’s heart rhythm and advises the rescuer whether a shock is needed to restore a normal heartbeat. If the patient’s heart resumes beating normally, the heart has been defibrillated.

The condition is often associated with progressive mitral regurgitation (blood flows back into the left atrium instead of moving forward into the left ventricle).

56
Q

A

Pertaining to the heart muscle (myocardium).

58
Q

Myocardial Infarction (MI)

A

Occurs when a focal area of the heart muscle dies or is permanently damaged because of an inadequate supply of oxygen to that area; also known as a heart attack. The most common symptom of a heart attack is angina, which is chest pain often described as a feeling of crushing pressure, fullness, heaviness, or aching in the center of the chest. Many times people try to ignore the symptoms or say that “it’s just indigestion.” It is imperative to seek medical help immediately. Calling 911 is almost always the fastest way to get lifesaving treatment.

60
Q

Occlusion

A

A blockage in a vessel, canal, or passage of the body.

61
Q

Oximetry

A

Process of measuring the oxygen saturation of blood. A photoelectric medical device (oximeter) measures oxygen saturation of the blood by recording the amount of light transmitted or reflected by deoxygenated versus oxygenated hemoglobin (Hgb). A pulse oximetry is a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin.

62
Q

Oxygen (O2)

A

Colorless, odorless, tasteless, gas essential to respiration in animals.

63
Q

Palpitation

A

An abnormal rapid throbbing or fluttering of the heart that is perceptible to the patient and may be felt by the physician during a physical exam.

64
Q

Percutaneous Transluminal Coronary Angioplasty (PTCA)

A

Use of a balloon tipped catheter to compress fatty plaques against an artery wall. When successful, the plaques remain compressed, which permits more blood to flow through the artery, therefore providing more oxygen to relieve the symptoms of coronary heart disease.

65
Q

Pericardial

A

Pertaining to the pericardium, the sac surrounding the heart.

66
Q

Pericardiocentesis

A

Surgical procedure to remove fluid from the pericardial sac for therapeutic or diagnostic purposes.

67
Q

Pericarditis

A

Inflammation of the pericardium (outer membranous sac surrounding the heart).

68
Q

Peripheral Artery Disease (PAD)

A

Pathological condition in which fatty deposits build up in the inner linings of the artery walls. These blockages restrict blood circulation, mainly in arteries leading to the kidneys, stomach, arms, legs, and feet. In its early stages, a common symptom is cramping or fatigue in the legs and buttocks during activity. Such cramping subsides when the person stands still. This is called intermittent claudication. If left untreated, PAD can progress to critical limb ischemia (CLI), which occurs when the oxygenated blood being delivered to the leg is not adequate to keep the tissue alive.

69
Q

Phlebitis

A

Literally means inflammation of a vein. There will be redness (erythema), swelling (edema), and pain or burning along the length of the affected vein.

70
Q

Phlebotomy

A

Medical term used to describe the puncture of a vein to withdraw blood for analysis.

71
Q

Raynaud Phenomenon

A

Disorder that affects the blood vessels in the fingers and toes; it is characterized by intermittent attacks that cause the blood vessels in the digits to constrict. The cause is believed to be the result of vasospasms that decrease blood supply to the respective regions. Emotional stress and cold are classic triggers of the phenomenon, and discoloration follows a characteristic pattern in time: white, blue, and red.

72
Q

Rheumatic Heart Disease

A

Pathological condition in which permanent damage to heart valves is a result of a prior episode of rheumatic fever. The heart valve is damaged by a disease process that generally originated with a strep throat caused by streptococcus A bacteria.
