Q

Can high flow rates (8L/min) improve the size of infarct?

A

No. False. High flow oxygen can actually worsen size of infarct.

Q

What drug should you give a pt if nitro is ineffective?

A

Initially, you’ll have increased O2 demand, BP, HR, and contractility. Then you’ll give the patient morhpine. This will subsequently decrease all of these values.

Q

Primary PCI

A

Angiogram, insert STENT to re-establish perfusion distal to the occlusion. Can elect for this is there is a significant occlusion and they want to take preventative action to prevent an MI.

Q

TIs for PCI (percutaneous coronary intervention)

Study These Flashcards
A

-Electively for chronic, stable, angina
-Urgent for unstable angina
-Emergent for MI
-1-2 vessel disease
-Perform within 120’ of first medical contact, ideally within 90’

19
Q

What are some complications of PCI ?

Study These Flashcards
A

-Restensois
-Coronary artery spasm
-Puncture or damage
-Irritation to the heart
-Bleeding
-Risks of heparin use

20
Q

What are the nursing interventions for follow-up care post-PCI?

Study These Flashcards
A

-Angina
-Vascular site care
-Peripheral ischemia
-Renal protection

20
Q

What meds are given 120’ following a PCI?

Study These Flashcards
A

ASA 160mg
Fibrinolytic IV (STEMI only)
Plavix 300mg
UF Hep bolus 60, + cont. drip 12u/kg/hr

21
Q

What meds are given immediately for a PCI?

Study These Flashcards
A

ASA 160, Plavix 300, UF hep 70U/kg, standing by for transfer to Cath lab

22
Are we always worried about angina following an MI?
No. This may be caused by a transient coronary vasospasm, but it can also be a more serious complication
23
How do we assess for kidney function and why are we worried following a PCI?
The dye used is bad for kidneys, as is metformin. Look at hydration, fluids, D/C of some meds
23
Timing of fibrinolytic therapy
30', ideally in first hour, less than 6hrs otherwise we just won't give it because the risks are too great.
24
Do we treat dysrhythmias in fibrinolytic therapy ?
No, they are self limited. NO tx
25
What are some relative CIs for fibrinolytic therapy
-Active peptic ulcer disease -Anticoagulant -Pregnant -Hx ischemic stroke not last 3month -Dementia -Sugery in last 3week -Internal bleeding last 204wek -Severe HTN -Traruma or prolonged cardiopulmonary resuscitation
25
What is the major complication in fibrinolytic therapy?
Bleeding. We are looking at superficial bleeding (IV site) or internal bleeding where we would then stop the infusion and observe for stroke symptoms.
26
Who is eligible for fibrinolytic therapy?
-Recent onset (12hr) persistent ST-elevation, Bundle Branch blocks (BBB's), chest pain UR Nitro, NO conditions w. predisposition to hemorrhage
27
Who are we NEVER giving fibrinolytic therapy to?
-Internal bleeding -Hx cerebral aneurysm/AV malformation -Hx cerebral hemorrhage -Ischemic stroke Hx last 3mth -Closed head/facial trauma 3mth -Suspected aortic dissection
28
When would you elect for a coronary artery bypass graft?
When there are blockages but a stent is not appropriate. Not usually an emergency surgery.
29
What vein is used for a coronary bypass graft?
Saphenous from the Breast or leg. Placed into the heart to bypass the area where there is an occlusion. Allows us to re-establich perfusion distally.
30
TI for CABG
Left main disease, multi vessel disease, satisfactory improvement is not reached with medical management, patient is not a candidate for PCI, lifestyle limiting angina unresponsive to therapy or PCI
31
Post MI ongoing assessment and care
1) PAIN 2) Bleeding/skin/tubes/wires 3) catheter, extremeties 4) Monitor cardio, resp, VS, O2 5) rest/sleep 6) Anxiety 7) Efficacy 8) Psychological response
32
What ventricle are we US to check ejection after an MI?
Left.
33
How long to discharge most patients after an MI?
1 week
34
How would you educate your patient prior to discharge?
1-manage pain and ID PF (precipitating factors) 2-ID personal risk and lifestyle changes to make 3-Sexual activity may resume when they can climb 2 flights of stairs 4- stick to ur drug regime (duh)
35
Which antiplatelet will a pt be on for the rest of their lives?
Aspirin
36
When would you prescribe plavix in LT drug therapy?
Allergic to ASA or if they have a stent
37
Describe dual antipltelet therapy ?
For one year, then change in protocol. ASA + Tricagrelor//plavix
38
What is recommended for all patients with ACS ?
Statin therapy
39
What is the statin protocol for patients?
Manages cholesterol. Atorvastatin 80mg daily of Rosuvastatin 20-40mg daily.
40
Why do we prescribe ACE inhibitors in LT management ?
Regulare BO, prevent remodelling of Left ventricle, ramipril, captopril
41
Why do we prescribe beta-blockers to pts for LT drug therapy ?
decrease: contractility, heart rate, after load, lower O2 demand and increase supply Metoprolol, atenolol
42
Describe why and how you would take nitro in LT disease management
-PRN -Before activity Promotes peripheral vasodilation and enhances collateral flow. Increase BF to ischemic zones
43
When and why do we prescribe calcium channel blockers?
Coronary and peripheral vasodilation, reduced contractility,used in combination with beta boclkers, Diltiazem, verapamil, nifedipine
44
What are some complications you may see in patients following an MI?
Arryhtmias, CHF, cariogenic shock, papillary muscle dysfunction, ventricular aneurysm, pericarditis, pulmonary embolism
