(157 cards)
valvular stenosis
- tissues forming the valve leaflets become stiffer, narrowing the valve opening and reducing the amount of blood that can flow through it
- heart murmur
valvular insufficiency
- leaflets do not close completely, letting blood leak backward across the valve
- heart murmur
ventricular septal defect (VSD)
- abnormal opening (hole) b/t ventricles
* heart murmur
coronary artery disease (CAD)
- atherosclerosis
- affected by lifestyle
- leading cause of death
arteriosclerosis
•blood vessels that carry oxygen and nutrients from your heart to the rest of your body (arteries) become thick and stiff
•restricts blood flow to your organs and tissues
•20-40 mmHg change in systolic
•increased pulse pressure
*hardening of arteries
atherosclerosis
- type of arteriosclerosis
* buildup of fats, cholesterol and other substances in and on your artery walls (plaques), which can restrict blood flow
pulse pressure
•difference b/t systolic and diastolic
arrhythmia
- conduction disorders
- irregular heart beat
- ectopic beats
angina
- severe chest pain
- heart muscle ischemia
- r/t lack of O2 to heart muscle
myocardial infarction
- heart attack
* r/t NO O2 getting to heart muscle
orthopnea
- difficulty breathing when laying down
* must be upright to breathe
paroxysmal nocturnal dyspnea (PND)
•wake up short of breath
hypoalbuminemia
- low albumin levels
* causes edema
bruit
- turbulent blood flow
* swooshing sound
thrill
•palpable vibration
sinus arrhythmia
- HR varies w/ breathing
* common in children
midsystolic click
- extra heart sound r/t murmur
* most common MVP
friction rub
- extra heart soud r/t murmur
* a scratching or squeaking sound
rheumatic heart dz
•reduced fxnl capacity of heart
mitral valve prolapse
- mitral valve doesn’t close
- leaky valve
- more common in women
- causes mid systolic click sound
- doesn’t usually cause problem for pt
intraluminal valves
- in veins
* help blood flow back to heart against gravity
pit
- depression left for 5-30 sec
- 1+: 2 mm
- 2+: 4 mm
- 3+: 6 mm
- 4+: 8 mm
thrombosis
- blood clot
* local
embolism
- blood clot
* traveling thrombosis
