Pathology Exam 5 Flashcards
condition or factors that make a person more susceptible or more inclined to a particular disease.
Predisposing factors
Predisposing factors
- Heredity 2. Obesity 3. Diabetes 4. Elevated cholesterol levels 5. Social factors a) Smoking b) Substance abuse c) Stress - type A personality d) Diet
increase in the length or stretching of the heart by the fibers making it up. This is a temporary condition. An example would be blowing up a balloon and letting the air out immediately.
Dilatation
increase in size of the heart muscle by an increase in the size of the heart cells itself.
Hypertrophy
inflammation of the endocardium, the inner most layer of the heart, the layer of the heart from which heart valves are made
Endocarditis
Valvular defects
Insufficiency Stenosis Prolapse
The most common heart valve where valvular defects takes place
mitral valve. Because of its structure, only heart valve that has two distinct sections or cusps making it up.
A valvular defect(incompetence) failure of a heart valve to close or seat properly.
Insufficiency
A valvular defect(narrowing) a narrowing or reduction in the size of the opening controlled by a heart valve.
Stenosis
A valvular defectweakening in a wall of a heart cusp; collapse of one of the cusps making up a heart valve.
Prolapse
inflammation of the pericardium - the sack surrounding
Pericarditis
inflammation of the myocardium - the muscle layer of the heart
Myocarditis
this is contagious. Caused by StreptococcusPyogenes (a strict pathogen) and Ashoff bodies (scar tissue). The scar tissue which form in persons who recover from the childhood disease rheumatic fever.
Rheumatic heart disease
a disease affecting the coronary arteries (first and only branches off the arch of aorta)
Coronary artery disease
dealing with Coronary artery disease the early stages of the hardening of the arteries; a disease with the presence or formation of atheromas (fatty plaques). This disease tends to present itself in tortuous arteries
Atherosclerosis(make sure you look at the name and the definition; always check the spelling)
dealing with Coronary artery disease arteries that can quickly change the volume of blood flow through them
tortuous arteries
dealing with Coronary artery disease the presence of an attached blood clot during life in the coronary arteries. (strepto pyogenes could be injected to dissolve the clot) Possible cause of coronary artery disease
Thrombosis
dealing with Coronary artery disease abnormal contraction of the heart muscle. Present themselves to let the doctor know the patient has a coronary artery disease.
Spasms (fibrillation)
dealing with Coronary artery disease the presence of a free floating object in the blood stream. Possible cause of coronary artery disease
Embolism
failure of the heart to deliver oxygenated blood throughout the body
Cardiac failure
massive - failure of the heart suddenly. Sudden onset and of short duration
Acute
cardiac failure comes on slowly and lasts a long time. Slow and chronic
Chronic
congestive heart failure- Usually occurs in adulthood. In adults the persons heart was not beating as fast as it should; swollen ankles are indicative of CHF; children- generally a result of improper structural changes that fail to occur at birth or shortly thereafter.
**
Death of heart muscle tissue caused by interference in blood supply. Commonly known as a heart attack; it could be mild (dead muscle tissue but not enough to kill the person).
Myocardial infarction
