Social Security Disability Insurance=SSDI
A program that provides monthly benefits to people who have worked and paid social security taxes but are now unable to work due to a disability. eligibility= significant work history and a severe disability that is expected to last at least one year or result in death.
Supplemental Security Income=SSI
A need-based income program that provides cash assistance to individuals with disabilities with limited income and resources, regardless of their work history. also available to children with disabilities.

healthcare access for patients with disabilities
-evaluate the patient’s ability to obtain required health care and recommended health screening
-ensure that appropriate modifications have been made so that people with disabilities can receive health care equal to that of people without disabilities
-examine facilities and procedures to ensure that the needs of people with various disabilities can be adequately addressed
-consider the effects of aging on a pre-existing disability and in turn the effects of disability on aging
Chronic disease and disability
Some degree of disability is often present in severe or advanced chronic illness (>3 months), such as:
-stroke
-diabetes
-obesity
Disabilities may be due to:
-genetics
-injury
-medical procedures
-accidents
-chronic conditions
Perfusion circulation
Blood pumped from the heart through a network of arteries, which branch into smaller arterioles and then into even smaller capillaries. the capillaries are where the actual exchange of oxygen, nutrients, and waste occurs.
Perfusion exchange
In the capillaries, oxygen and nutrients diffuse from the blood into the tissues, while waste products like carbon dioxide move from the tissues into the blood.
Perfusion return
After passing through the capillaries, the now-deoxygenated blood is collected by venules and veins, which return it to the heart. from there, it is pumped to the lungs for oxygenation before being sent out to the rest of the body again.
Importance of oxygen and nutrients in the body/perfusion
Adequate perfusion is crucial for delivering oxygen and nutrients to tissues and organs. without it, cells can suffer from hypoxia and nutrient deficiencies, which can lead to cell damage or death.
Assessment of perfusion
BP, HR, O2 sat, cap refill, skin assessment (color, temp, moisture), pulses, LOC, urine output
Cardiac biomarkers/labs
-troponin: sensitive and #1 test- protein released in blood with heart injury
-CK: muscle breakdown
Which coronary artery supplies blood to both ventricles?
Left anterior descending= LAD (interventricular artery)
Coronary artery disease= CAD
Ischemic heart disease; coronary arteries become narrowed or blocked due to atherosclerosis.
Symptoms of CAD
-may vary
-might not experience symptoms until advanced disease
-angina= chest pain or discomfort
-shortness of breath
-heart attack= a sudden, severe event where the blood flow to part of the heart muscle is blocked for a prolonged period, potentially leading to heart muscle damage.
-typical chest pain in men include heavy crushing, “elephant on chest”, center or left side of the chest, radiating to left arm or jawline
-atypical chest pain in women includes sharp, burning, indigestion, discomfort to back, shoulders, abdomen, jaw pain
-N/V
-Pale skin
-Fatigue
-Dizzy, lightheaded
-Palpitations
Risk factors of CAD
High cholesterol, HTN, tobacco use, diabetes, obesity, physical inactivity, unhealthy diet (high in saturated and trans fats, cholesterol), stress, family history (genetics), increasing age, male gender, race, premature menopause, social determinants of health (lower socioeconomic status), air pollution.
Assessment of CAD
VS, pain, EKG and continuous cardiac monitoring/telemetry, perfusion, skin, GI, respiratory, patient hx (risk factors, angina pattern), recreational drug use (cocaine use/induced vasospasm leads to MI), lab values:
-cardiac biomarkers=troponin, CK, CK-MB
-Creatinine, BUN
-Glycosylated hgb (HgbA1c)
-lipid profiles=cholesterol, triglycerides, LDL, HDL
Health promotion for CAD
Goal=reduce risk for developing CAD
-reduce cholesterol level- diet, weight reduction, exercise, medications (statins)
-smoking cessation
-manage HTN
-good glycemic control for diabetics
-manage stress
-attend follow up appointments
Medications for CAD
-cholesterol-lowering drugs= statins
-antiplatelets- ASA, clopidogrel
-anticoagulants= warfarin, rivaroxaban, apixaban
-antihypertensives- BB, CCB, ACE, ARB
-nitrates to manage angina= nitroglycerin, isosorbide
Angioplasty and stenting
catheter with a balloon is used to open up narrowed arteries, and a stent is placed to keep the artery open= percutaneous coronary intervention
-indicated with high risk stable angina and unstable angina
coronary artery bypass grafting=CABG
surgery where a healthy artery or vein from another part of the body is used to bypass the blocked coronary artery
-indicated with high risk stable angina and unstable angina
-no heavy lifting 4-8 weeks afterward
-epicardial/pacing wires are temporary and can be atrial or ventricular. dressing changes every 24 hours. can be implanted or outside wires.
-chest tube: NEVER more than 100 mL/hr
Primary angioplasty MI= PAMI
procedure when vessel is occluded and need to open it up
cardiac catheterization
a thin flexible catheter is inserted into a blood vessel (femoral or radial artery=radial preferred) and guided to the heart using fluoroscopy to diagnose and treat heart conditions if necessary.
-purpose:
-diagnosis: angiography used to assess the function of the heart, measure pressures within the heart chambers, and evaluate the heart’s blood supply
-treatment: PCI- interventions such as balloon angioplasty, stent placement, or biopsy of the heart tissue
-risks: infection at insertion site, bleeding or hematoma, allergic reaction to contrast dye, rarely heart attack or stroke
-VS q 15min for 1st hour after cath-lab
ASSESS FOR BLEEDING
cardiac/coronary angiography
-type of imaging done to visualize the inside of the coronary arteries and assess the presence and severity of blockages.
-purpose:
-diagnosis: to identify the location and extent of blockages or narrowing in the coronary arteries.
-guidance: to guide treatment decisions, such as the need for angioplasty, stenting, or bypass surgery.
-procedure: injection of contrast dye into the coronary arteries through a cardiac catheter, x-ray images taken as the dye flows through the coronary arteries, providing a detailed view of the blood vessels and any blockages or abnormalities.
-risks: allergic reaction to dye, kidney damage due to contrast dye, discomfort or bruising at the catheter insertion site, rarely heart attack or stroke.
PCI= percutaneous coronary intervention/balloon angioplasty with a stent
treatment for narrowed or blocked coronary arteries discovered during cardiac catheterization. restores blood flow and perfusion to cardiac muscle.
-procedure: cardiac insertion, balloon inflation at area of blockage, stent placement in area where blockage was to prevent restenosis
-no metformin 48 hours before, need distal pulses afterward, no bending leg 4-6 hours post if femoral
-patient medication education: low dose ASA indefinitely, clopidogrel/plavix for 6-12 months
Angina
episodes of chest pain caused by decreased perfusion of the heart muscle- increased oxygen demand, decreased oxygen supply to heart muscle.
-three types: stable, unstable, variant (prinzmetal’s)
-stable and unstable: symptoms of CAD, precursor to MI
-variant: caused by vasospasm NOT atherosclerosis
Angina pectoris- stable angina
episodic chest pain because of inadequate oxygen supply to the heart, most often due to obstruction in the coronary arteries
-most common type of angina
-pain often presents as pressure, fullness, squeezing pain in the center of the chest
-angina= ischemia in the subendocardium- triggers release of adenosine and bradykinin-pain
Angina pectoris- unstable angina
episodic chest pain that either:
-is new in onset
-occurs at rest unpredictability
-rapidly worsens over time
-occurs within 48 hours after acute MI
usually caused by ruptured atherosclerotic plaque-formation of thrombosis on top of plaque- almost complete blockage in blood vessel-ischemia-pain
-medical emergency!!! high risk of progression to MI
(angina has myocytes still alive, myocardial infarction has death of myocytes)
Assessment of angina
-stable: predictable pattern, occurs with activity, subsides with rest and/or administration of nitro
-unstable: attacks that increase in frequency and severity, occur at rest with no pattern (prolonged episodes, not relieved by rest, require medical intervention like PCI or CABG, treat as emergency)
Symptoms of angina
chest pain, apprehension, anxiety, feeling of impending death/doom, SOB, pallor, diaphoresis, hypotension, dizziness or lightheadedness, N/V
-diabetics commonly have no symptoms!
Angina solutions
decrease oxygen demand of myocardium and increase oxygen supply
-stable: pharmacologic therapy, control of risk factors
-unstable: PCI, CABG
ABCDE: Aspirin and antianginal therapy, Beta blockers and blood pressure, Cigarette smoking and cholesterol, Diet and diabetes, education and exercise
Taking action for angina
-stop activity
-place in semi-fowler’s position
-EKG WITHIN 10 MINUTES OF ARRIVAL TO ED
-VS
-NTG SL q5 minutes up to 3 doses- assess BP, HR, ST segment before each dose
-2 large bore IVs
-draw cardiac biomarkers: troponin, CK, CK-MB
-administer o2
-telemetry
-prep for cardiac cath WITHIN 90 MINUTES OF ARRIVAL TO ED
-reduce anxiety
Acute coronary syndrome= ACS
umbrella term for group of conditions:
1. unstable angina
2. non-ST elevation MI=NSTEMI
3. ST elevation MI= STEMI
-MEDICAL EMERGENCY- URGENT DIAGNOSIS AND CARE
-Treatment goals: improve/restore coronary blood flow, treat complications, prevent MI and complications
Assessment of unstable angina
manifestations of coronary ischemia, but ECG and cardiac biomarkers show no evidence of acute MI
-ST depression, T wave inversion- transient and reversed with relief/tx of angina
-normal cardiac biomarkers (troponin)
-no necrois, minimal occlusion
Assessment of NSTEMI
elevated cardiac biomarkers (troponin), no definite ECG evidence of acute MI, may be less damage to the myocardium
-ST depression, T wave inversion
-Elevated cardiac biomarkers (troponin)
-necrosis, severe occlusion
-MI
Assessment of STEMI
elevated cardiac biomarkers, ECG evidence of acute MI with characteristic changes in two contiguous leads on a 12-lead ECG, significant myocardial damage.
-ST elevation
-Elevated cardiac biomarkers (troponin)
-transmural necrosis, complete occlusion
-fireman’s hat!
-MI
To determine if angina or MI
-cardiac catheterization: evidence of occlusion
-stress test (exercise of pharmacologic): performed if no EKG changes present or rise in troponin
Myocardial Infarction= MI
plaque rupture- thrombosis formation-complete occlusion of artery- ischemia-necrosis of the myocardium
-infarction develops over minutes to hours- permanent damage to myocardial tissue
-ischemic cardiac muscle- cardiac enzymes released into the bloodstream
TIME IS MUSCLE!! early recognition and treatment improves chances of survival
-must have elevated cardiac biomarkers and one of: 1-S/Sx of ischemia, 2- EKG changes, 3-damage to heart wall on echo
-extent of damage is associated with MI location- LAD worst
