what is a common cause of systolic HF

A

MI

32
Q

why is there reduced contractility with systolid HF

A

loss of cardiomyocytes

33
Q

describe the alteration of chamber volume for all 3 cardiomyopathies

A

dilated - volume inc
hyper - vol dec (LV mainly)
restric - normal to dec

34
Q

inflammation of the pericardium

A

pericarditis

35
Q

S1 heart sounds

A

closure of AV valves at start of systole

36
Q

what are 4 characteristics of myocarditis

A

left ventricular dysfunction
edematous heart muscle
normal endocardial structures
dilation of all 4 chambers

37
Q

what does trucus arteriosus cause

A

inc pul blood flow
pul HTN and RV hypertophy

38
Q

Heart sound: closure of AV valves at start of systole

A

S1 sound

39
Q

what are sdome clinical manifestations of dilated cardiomyopathy

A

general
chest pain
jugular vein distension
edema
pulm congestion

40
Q

what doe sthe RAAS activation do for HF

A

retains fluid
inc preload

41
Q

secondary cardiomyopathy

A

known cause and usually seend in the context of disorders taht affect the heart and other organs

42
Q

what is the becks triad

A

3 classic signs with pericardial disease

43
Q

pericardial effusion

A

accumulation of non-inflammatory fluid in the pericardial cavity

44
Q

hypertrophic cardiomyopathy is due to what

A

autosomal dominant disorder (cardiac sarcomere protein mutatiosn0

45
Q

what is a clinical manifestation fo coarctation of the aorta

A

low pressure in the legs

46
Q

primary cardiomyopathy

A

confined to the myocardium

47
Q

cardiomyopathy

A

non-inflammatory disease of heart muscle

48
Q

what are some causes of primary cardiomyopathy

A

myocardial disorders - HTN, ischemic, congenital, valvular, pericardial, inflammatory

49
Q

what does PDA cause

A

inc pul blood flow
inc pul venous return to LA and LV - inc workload
pul HTN - right side HF

50
Q

what effect does pericardial effusion have on the heart

A

the fluid compresses the heart and it cannot expand to fill - lowers CO and highers HR

myocardial hypertrophy and remodeling results from

A

chronic elevation of myocardial wall tension

54

hypotension
distended neck veins
muffled heart sounds

58
Q

what are two main causes of diastolic HF

A

CAD and HTN

59
Q

heart murmurs causes

A

turbulent blood flow

60
Q

what is dilated cardiomyopathy most commonly due to

A

inc pulmonary flow
pulm HTN

65

describe PDA

A

ductus arteriosus doesnt close, allows blood to go from aorta to pulmonary artery

70
Q

systolic HF has what result on EF and CO

A

Ef under 40%
lower CO

71
Q

what is the RAAS used for

A

to increase BP

72
