Types of dietary fat:
Saturated - use sparingly
Animal fat (bacon, lard, egg yolk, dairy)
Butter, cream cheese, sour cream
Monounsaturated - good
Oils- fish, canola, peanut, olive
Avocado, nuts (almond, peanuts, pecans), olives
Polyunsaturated - use sparingly
Vegetable oils (safflower, corn, soybean, cottonseed, flaxseed)
Some fish oil and shellfish
Seeds (pumpkin, sunflower)
Margarine
Cholesterol-lowering drug therapy:
o
Drugs that restrict lipoprotein production - statins (Lipitor, Zocor, Niacin)
stabilize plaque
o
Drugs that increase lipoprotein removal - bile acid sequestrants (Questran)
o
Drugs that decrease cholesterol absorption - Zetia
Anti-platelet therapy: low-dose aspirin or Plavix
Use statins to prevent plaque rupture (thromboembolism
Gerontologic considerations:
o
Greater incidence and cause of death
o
Diligent management of HTN and hyperlipidemia will help to stabilize plaques
in coronary arteries
o
Same health promotion strategies, with modifications - longer warm up, longer
periods of lower level activity, longer rest periods
o
Avoid exercise in environmental extremes as older adults have less efficient
sweating & may develop heat intolerance

o
Assess readiness for education
b.
Angina pectoris
i.
Insufficient blood flow, leading to anaerobic metabolism and lactate within 10 seconds of
coronary occlusion
ii.
when artery is narrowed and obstructed by at least 75%: stenosis
iii.
Assessment
Signs/Symptoms:
o
Pain: usually lasts less than 15 mins
Varies in intensity—“crushing”
Felt deep in the chest; retrosternal, substernal
May radiate to jaw, shoulder, back
Decreased or absent in diabetics and elderly
May be absent in women
o
Weakness or numbness in arms, wrists, and hands
o
Shortness of breath
o
Prodromal symptoms: (under-diagnosed; may present with unstable angina
before CAD is diagnosed; fatigues occurs in many illnesses)
Fatigue, SOB, indigestion, anxiety
o
Precipitating factors:
Physical exertion
Exposure to cold
Eating a heavy meal
Stress or any emotion-provoking situation
Smoking
iv.
Management
Relieve chest pain, decrease myocardial O2 demand
o
MONA
: morphine, oxygen, nitroglycerin, aspirin
Aspirin thins the blood and protects the heart
Nitroglycerin dilates blood vessels, making it easier for blood to flow
through
o
Pharmacologic therapy: thrombolytic therapy within 1-3 hours of symptoms or
30 mins in ED (“door to needle time”), i.e. t-PA, Activase = tissue plasminogen
activator dissolves all clots
o
Heparin infusion prevents future clots
o
12-lead EKG, blood work
o
Increase oxygen supply: ACE-inhibitors, Beta-blockers
o
Promote adequate tissue perfusion
o
Reduce anxiety
o
Monitor and manage complications
o
Patient teaching
v.
STEMI:
Transmural infarction of the myocardium (the myocardium has undergone necrosis
resulting in ST elevation. Usually due to occlusive thrombus)
Requires thrombolytics like Streptokinase to lyse the thrombus
Give TPA infuse in blood vessels or heart to diffuse the clot
vi.
NSTEMI
A partial dynamic block to coronary arteries (non-occlusive thrombus) no ST elevation of
Q waves on ECG
