Conditions of the Cardiovascular System P.P. (Week3) Flashcards
MI
gross necrosis of the myocardium due to interruption of the blood supply to the area
If the blockage is below 40% patient usually does not know they have __________
artherosclerosis
Client will have 50% or more blockage when symptoms begin to show in _______
artherosclerosis
Signs and symptoms of MI ( 6)
- Chest pain/pressure
- shortness of breath
- nausea/vomiting
- weakness
- diaphoresis/sweating
- sudden death
dyspnea
difficulty breathing
SOB is usually what a person experiences after ____ ____
physical activity
MI causes ____ due to pressure on the chest.
dyspnea
If the pressure of what is thought to be an MI goes away it is most likely ______
angina
Diagnosing an MI (3)
- blood work
- EKG
- Chest xray
Cardiac markers such as CK-MB and Troponins are signs of
MI
Troponins are
released in the blood system when the heart muscle dies.
EKG shows an elevation in the ___
ST interval
Causes of an MI (6)
- Thrombus (clot) formation at the site, or that travels to (embolism) a narrowed vessel
- Atherosclerosis/plaque formation
- vaspospasm
- hypotension
- anemia
- cocaine use
embolism
a clot that travels
Thrombus
clot that is caught in a narrow vessel
A thrombus that gets caught in a vessel with atherosclerosis causes an
MI
Vasospasm
vessels constrict distally and peripherally to protect the body (keep warm)
When a vasospasm occurs to a main artery it can mimic a
MI
As angina worsens the heart will grow new vessels around the partially blocked vessels. This is called
collateral circulation
Atherosclerosis is
plaque formation in the coronary artery blocking blood flow and oxygen to the heart
What is the most common type of HD?
CHD
CHD can lead to
MI, angina and other complications
Decline in HD deaths are due to (2)
- people are reducing their own risk factors
2. New medications and procedures are preventing HD
MAJOR Risk factor of CAD (4)
- smoking
- high cholesterol/lipids
- hypertension/ high BP
- Diabetes Mellitus (DM)
All MAJOR CAD risk factors are _________
modifiable
High blood pressure is caused by ______
inflammation in the coronary arteries
High blood pressure can cause a ___
stroke
Exercise increases ___
HDL
Medication and diet will decrease ____
HBP
Avoid DM by (2)
- Dieting
2. Exercising
Minor Risk Factors for CAD (8)
- sedentary life style
- family hx
- aging process
- abdominal obesity
- psychosocial factors - high stress
- consumption of too few fruits/vegetables
- drinking too much alcohol
- high inflammation in the body (RA)
Visceral fat is
abdominal obesity
1 way to prevent CAD
risk factor reduction: quit smoking check for hypertension and lose weight check for diabetes and lose weight check for high cholesterol lose weight exercise take medication as directed
“MOAN” the immediate treatment for MI stands for
Morphine - for pain/anxiety relief
Oxygen - To help heart work better
Aspirin - to “thin” the blood for better circulation
Nitroglycerin - to vasodilate blood vessels to improve circulation
Immediate tx in ER for CAD
- Iv fluids
- oxygen
- EKG
- Blood tests
- Possible t-PA
What is t-PA?
Clot-buster - dissolves clot to avoid more clots/blockages
Why shouldn’t a person that has had CPR be administered t-PA?
t-PA is a blood thinner that will loosen up all blood from bruising and the patient can bleed out
Long term medications for tx of CAD(6)
REMEMBER THIS LIST!!!! SIDE-EFFECTS WILL BE GONE OVER IN ANOTHER PRESENTATION
Asprin, plavix Beta blockers Calcium channel blockers ACE-inhibitors Nitroglycerin Statins
Nitroglycerin is sent home with patients if
They still have small blockages elsewhere
percutaneous
through the skin
transluminal
across the lumen
Revascularization Techniques for CAD (2)
- PTCA with stenting
2. Coronary Artery Bypass Graft (CABG)
What is the procedure for percutaneous transluminal coronary angioplasty (PTCA) with stenting?
A catheter pushes the plaque up against the walls of the artery and then a stent is placed to hold the vessels open
What happens if a stent can not be placed due to an area of blockage?
A CABG will be performed
What is the procedure for a CABG?
A vein is removed from another part of the body,then
flipped upside down so the valves stay open, and secured onto the heart bypassing blood flow around the site of the blockage.
Which veins can be used for a CABG? (3)
- Saphenous
- Internal mammary
- radial artery
Complications of an MI include (5)
- arrhythmias
- continued angina/chest pain
- pericarditis
- heart failure (CHF)
- DVT
arrythmias
abnormal, irregular hear rhythm
pericarditis
inflammation around the heart
CHF
decreased cardiac output, reduced/low ejection fraction
DVT stands for
deep vein thrombosis
A DVT is
blood clot in leg
What can happen if a DVT travels?
It can end up in the lungs causing a pulmonary embolus
Symptoms of Pulmonary embolus (2)
Chest pain
SOB
3 types of CHF
- left-sided systolic HF
- right-sided diastolic HF
- Right-sided HF
Symptoms of Class I (Mild) HF
No limitation of physical activity; does not cause undue fatigue, palpitation, or dyspnea.
Symptoms of Class II (Mild) HF
Slight limitation of physical activity; comfortable at rest but ordinary activity causes fatigue, palpitation,, or dyspnea
Symptoms of Class III (Moderate) HF
Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes fatigue, palpitation, or dyspnea
Symptoms of Class IV (Severe) HF
Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency at rest. If any physical activity is undertaken, discomfort is increased.
Risk factors of DVT(4)
- Long travel
- cancer patients
- use of estrogen
- Other
Prevention of DVT
- early ambulation
- “foot board” - exercises while still in bed
- SCD - sequential compression devices
- Medications - lovenox
Biggest risk of a DVT is if a
clot travels to the lungs and causes a deadly PE
Heprin vs Coumadin
Heprin is short acting
Coumadin is long acting
Cardiac rehab will focus on (3)
- Safe EXERCISE with telemetry monitoring
- Proper EDUCATION to reduce cardiac risk
- DIETARY EDUCATION to help reduce cholesterol and BP (sodium) in diet via demos, classes
Exercise helps create
new vessels
Which exercises are used in cardiac rehab? (3)
- Stretching
- Aerobic - creates new vessles
- Strength and balance
Strength and balance exercise will decrease the risk of
falls
Cardiac diet consists of eating(3)
- low carbs
- lean fish, meat, poultry = no skin, no fat
- tons of fruits and vegetables
Cardiac catheterization
is a procedure used to diagnose and treat cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in your groin, neck or arm and threaded through your blood vessels to your heart.
