Cardiovascular disorders, diagnostic, and therapeutic procedures Flashcards
Modifiable risk factors of CAD
Elevated serum cholesterol Cigarette smoking Hypertension Impaired glucose tolerance/DM Obesity Excessive alcohol Limited physical activity Stress Postmenopause (modification is controversial)
non modifiable risk factors of CAD
Age
Gender
Family history
Ethnic background
collateral circulation
tiny blood vessels form to re route blood around a blocked artery
2 types stable angina
Silent ischemia -Associated with diabetes mellitus (neuropathy-client does not feel painful sensations) and hypertension
Prinzmetal’s (variant) angina- Occurs at rest usually in response to spasm of major coronary artery
STEMI
ST elevation myocardial infraction
s/sx of MI
Chest pain , shortness of breath, diaphoresis, unstable angina
women s/sx of MI
includes regular signs of MI and fatigue pain in their back , shoulders, or jaw, N/V
Labs/Diagnostics of MI
Cardiac enzymes and abnormal ST elevation or depression, thallium scan , cardiac catherization,
Medications used for MI
Antiplatelet : Aspirin, Clopidogrel, Thrombolytics anticoagulants antihypertensive Betablockers Ace inhibitors statins
Surgical treatments for MI
PCI - Percutaneous Coronary intervention
CABG- Coronary Artery bypass graft
Atherectomy- removal of plaque from artery
Nursing care of MI
- admin oxygen for an sp02 less than 90% per order
- monitor PT for complications such as cardiogenic shock and HF
- initiate cardiac rehabilitation- program focuses on education and exercise for Patient
s/sx of cardiogenic shock
hypotension, tachycardia, tachypnea, and weak pulses
What is a PCI ?
Percutaneous coronary intervention- a procedure used to open up the coronary arteries and it must be done within 90min or less if hospital is PCI capable, if not then patient needs to be transported to hospital that has PCI within 120min or less of the onset of symptoms of MI
how does PCI procedure work ?
A catheter with a balloon is threaded through a blood vessel usually at the femoral artery , up to the blocked coronary artery. Then the balloon is inflated and a stent is placed to restore blood flow to the heart.
What happens after a PCI ? What should the nurse do ? Post OP?
- Monitor insertion site for bleeding and check perfusion to the extremity that is distal from that insertion site (check for for pulse, color and temperature)
- Monitor for complications : Artery dissection and re-occlusion of the coronary artery. Lookout for S/SX of SOB, chest pain, tachypnea, and tachycardia.
CABG procedure
Coronary Artery bypass graft (CABG) - bypasses one or more of the patients coronary arteries due to blockage or persistent ischemia, and usually uses the saphenous vein from the patients leg, however synthetic grafts can be used as well.
MIDCAB
Minimally invasive direct coronary artery bypass
alternative to CABG
Post OP for CABG Procedure
- monitor BP- hypertension/hi BP can cause bleeding from graph sites and Hypotension can cause collapse of the graft site
- monitor PTs temperature- post op hypothermia is a potential complication.
- monitor for bleeding, chest tube will be used after surgery so monitor for drainage of chest tube. if exceeds 150 ml per hour, notify HCP
- monitor LOC,F&E, cardiac rhythm and pain level. also monitor neurovascular level of donor site
- monitor Pts for complication of cardiac tamponade
