Q

Atherosclerosis Etiology

A

exact cause unknown

may begin w/ damage/injury to inner artery wall from hypertension, high cholesterol, smoking, diabetes

over time fatty plaques and other cell waste build up at site of injury & harden narrowing artery and impeding blood flow

17
Q

Cor Pulmonale Signs/Symptoms

A

progressive shortness of breath especially w/ exertion

also fatigue, palpitations, atypical chest pain, swelling in LE, dizziness and syncope

18
Q

Cor Pulmonale Treatment

A

supplemental O2 sufficient to maintain SaO2> 90% and/or PAO2> 60 mmHg
may also include diuretics & anticoagulants

19
Q

Coronary Artery Disease (CAD) Etiology

A

damage/injury to inner layer of coronary artery
fatty plaques and other cell wastes accumulate @ site of injury
if plaque ruptures, platelets clump to repair artery- which may create blockage = heart attack
Risks: high LDL cholesteral, type 2 DBM, smoking, obesity, physical inactivity, genetics, hypertension, hypothyroidism

20
Q

CAD Signs/Symptoms

A

degree of stenosis that produces S/S varies w/ O2 demand
diminished blood flow may = angina, shortness of breath, etc. which may not be felt till >70% of lumen occluded
complete blockage = heart attack

21
Q

CAD Treatment

A

Aggressive modification of risk factors = slow progression/ induce regression of existing plaques/restore/improve blood flow
includes: quit smoking, weight loss, heart-healthy diet (low sat. fats/ cholest./ Na), regular exercise, modification of serum lipids, control of hypertension/diabetes
Drugs: antiplatelet, ACE inhibitors, angiotensin II bockers, statins
Surgery: percutaneous angioplasty/ coronary artery bypass graft only for pts at high mortality risk

22
Q

Deep Vein Thrombosis (DVT) Etiology

A

any condition impairing normal circulation/ blood clotting
Risks: prolonged bed rest, inherited blood clotting disorder, injury/surgery of veins, pregnancy, cancer, birth control/ hormone replacement therapy, overweight, obesity, smoking

23
Q

DVT Signs/Symptoms

A

about 50% of cases are asymptomatic

may show swelling, pain, redness, warmth in affected leg

24
Q

DVT Treatment

A

GOAL: prevent blood clot from getting bigger/ breaking loose & causing pulmonary embolism
Meds: anticoagulants, thrombolytics
Prevent: compression stockings to reduce blood pooling in LE

25
Q

(Congestive) Heart Failure (CHF) Etiology

A

coronary artery disease (CAD), hypertension, diabetes mellitus, myocardial infarction, abnormal heart valves, cardiomyelopathy

26
Q

CHF Signs/Symptoms

A

shortness of breath, fatigue/weakness, swelling in legs/feet/abdomen, rapid/irregular heartbeat, persistent cough/wheezing, weight gain from fluid retention

27
Q

CHF Treatment

A

1) Treat underlying cause (repair damaged heart valve/ control abnormal rhythm)
2) balance meds, devices, and lifestyle changes to help heart contract normally
lifestyle changes: quit smoking, restrict Na intake, maintain healthy weight, limit alcohol/fluids, stress reduction, moderate exercise
meds= anticoagulants, antihypertensives, digitalis (increase strength of contraction)
3) SEVERE: surgery + medical devices

28
Q

Hypertension Etiology

A

Primary (essential) = no known cause

Secondary = usually due to renal disease

29
Q

Hypertension Signs/Symptoms

A

often asymptomatic until organ complications develop
Severe: (DBP> 120 mmHg) = CNS symptoms (confusion, cortical blindness, hemiparesis, seizures), cardiovascular symptoms (chest pain, dyspnea) and renal involvement

30
Q

Hypertension Treatment

A

Lifestyle Changes: aerobic physical activity 30 min/day, BMI of 18.5-24.9, quit smoking, reduced Na/alcohol intake, diet of increased fruits/ veggies/ low-fat dairy
Meds: diuretics, beta blockers, calcium channel blockers, ACE inhibitors, angiotensin II blockers, direct vasoldilators

31
Q

Hypertension Classifications:

A

Normal BP:

32
Q

Myocardial Infarction (aka Heart attack) Etiology

A

ruptured atherosclerotic plaque, blood clot blocks flow through coronary artery
uncommon = coronary artery spasm

33
Q

Myocardial Infarction Signs/Symptoms

A

chest discomfort w/ pressure, squeezing/pain, shortness of breath, UE discomfort (arms, shoulder, neck/back), nausea, vomiting, dizziness, sweating, and palpitations

34
Q

Myocardial Infarction Treatment

A

varies from meds - surgery-both depending on severity/ amount of heart damage
Meds: to treat acute MI = anitcoagulants, thrombolytics, pain relievers, antihypertensives, cholesterol-lowering meds

35
Q

Peripheral Artery Disease Etiology

A

primary = atherosclerosis, thromboembolic processes alter structure/function of aorta and its branches

36
Q

Peripheral Artery Disease Signs/Symptoms

A

fatigue, aching, numbness, pain in buttock/ thigh/ calf/ foot @ rest/when walking, poorly healing wounds of legs/feet, distal hair loss, trophic changes, hypertrophic nails

37
Q

Peripheral Artery Disease Treatment

A

for asymptomatic patients- quit smoking, lipid-lowering meds, control of diabetes/ hypertension
for pts w/ disabling intermittent claudication- revascularizing procedures (angioplasty/ stent/ lasers/ atherectomy), surgery
supervised exercise training 30-45 min 3xs/week for 12 wks

38
Q

Valvular Heart Disease Etiology

A

congenital defect, calcific degeneration, infective endocarditis, CAD, myocardial infarction, rheumatic fever

39
Q

`Valvular Heart Disease Signs and Symptoms

A

varies based on type/severity of valve disease- may include heart palpitation, shortness of breath, chest pain, coughing, ankle swelling and fatigue

40
Q

Valvular Heart Disease Treatment

A

Minimal Symptoms: may not require treatment
Moderate: meds to reduce heart workload/ regulate heart rhythm/ prevent clotting (digitalis, beta blockers, calcium channel blockers)
Severe: balloon valvulplasty/ surgery to repair/replace affected valve
