ch28 structural, infectious, and inflammatory Cardiac disorders Flashcards
is pressure on the heart that occurs when blood or fluid builds up in the space between the heart muscle (myocardium) and the outer covering sac of the heart (pericardium).
Cardiac tamponade
sometimes referred to as “fluid around the heart,” is the abnormal build-up of excess fluid that develops between the pericardium, the lining of the heart, and the heart itself.
Pericardial Effusion
Patients who present with either unstable angina or an acute myocardial infarction.
Develops when ischemia is prolonged and not immediately reversible.
Acute coronary syndrome
Complete occlusion of the artery causing irreversible myocardial cell death
Myocardial infarction
is a series of progressive events associated with cardiac dysfunction
Can lead to heart failure, dysrhythmias, or sudden death
In other words ……. The heart loses its ability to pump the blood
Cardiomyopathy
- increased atrial chamber size
- increased ventricular chamber size
- decreased muscle size
dilated cardiomyopathy
- thickened interventricular septum
- decreased ventricular chamber size
- left ventricular hypertrophy
hypertrophic cardiomyopathy
-left ventricular hypertrophy
restrictive cardiomyopathy
3 cardinal signs of cardiac tamponade: hypotension, muffled heart sounds, JVD
Beck’s triad
Inflammation of the inner lining of the heart and valves
Occurs primarily in patients who have prosthetic heart valves, structural cardiac defects, abuse IV drugs
Possible ports of entry—oral cavity, surgery
Hospital acquired -
endocarditis
Inflammation of the pericardium, the membranous sac that encloses the heart.
- Primary symptom is pain
- Most characteristic sign is a creaky or scratchy friction rub heard most clearly at the left sternal border. also fever, high WBC’s, anemia, elevated ESR or C-reactive protein, nonproductive cough or hiccough.
pericarditis
When valves do not close completely causing blood to flow backwards
regurgitation
when valves do not open completely and bloodflow through the valve is reduced
stenosis
stretching of the valve leaflet into the atrium during systole. It is a deformity that usually produces no symptoms.
- More frequent in women than men.
- These patients are at risk for endocarditis so teach pt. to practice good oral hygiene for prevention.
- should avoid alcohol and caffeine(cough syrup)
mitral valve prolapse
predictable and consistent pain that occurs on exertion and is relieved by rest and/ or NTG
stable angina
