Lecture Flashcards
what is unstable angina
new onset chest pain that occurs at rest or worsening in patter
state the conduction pahtway of the heart
SA node
Atria
AV node
Bundle of His
Bundle branches
ventricles
what does mitral stenosis result in
enlargement of LA and increase of its pressure
what causes myocrdial infacrtion
sustained ischemia causing irreversible myocardial cell death
what is aortic regurgitation
blood that flows back into LV during diastole - due to incompetent aortic valvewa
what is a cause of mitral stenosis
rheumatic fever
what is mitral stenosis
a calcified mitral valve that does not open proeperly - restricts forward flow of blood
what are the extra heart sound
S3: immediately after S2 (ventricles resistant to filling during protiadstole)
S4: just before S1 (ventricles resistant to filling during presystole
what is the leading cause of death in women older than 55
heart disease
why do older adults have an increased systolic BP
due to arteriosclerosis
what does aortic regurgitation result in
dilation and hypertrophy of LV (increased SV)
why do women have worse heart disease
due to decrease in ovary production of estrogne leading to higher LDL, BP and body fat
what is HTN
hypertension
calcification of aortic valve tha restrics forward flow of blood during systole
aortic stenosis
what is mitral regurgitation
blood flows back into LA due to incompetent mitral valve
what is a normal BMI
18.5-24.9
what is the second leading cause of death in canadians over 65 years old
cardiovascular disease
what are the normal heart sounds
S1: closure of AV valves
S2: closure of semilunar valves
describe the hemodynamic changes of older adults
Increased systolic
Decreased diastolic
