Prophylaxis is used in mitral valve prolapse patient to protect against _________.
Endocarditis
Surgical repair is indicated in mitral valve prolapse patient is severe mitral ___________ develops.
Regurgitation
This valvular disease is a narrowing of the aortic valve commonly due to degenerative calcification.
Sx include….
Angina
Syncope
Dyspnea
Aortic valve stenosis
Is aortic valve stenosis more common in men or women?
Men
What is a common (85%) EKG finding in patients with aortic stenosis?
LVH
T/F: Aortic stenosis is primarily managed medically and surgery is only indicated in severe symptomatic cases.
True
This valvular disease is results in a back-flow of blood from the aorta into the left ventricle due to an incompetent closure of the aortic valve.
Sx include…..
DOE
PND
Orthopnea
Aortic Valve regurgitation
Would you see expect to see LVH or LAD on an EKG in a patient with Aortic valve regurgitation?
A _______ pattern with one of the above would be concerning.
Yes
Strain pattern
T/F: Surgery is always indicated in patient with aortic regurgitation
False
Only in severe symptomatic cases, EX:declining EF
This is a valvular disease in which there is a narrowing of the pulmonic valve and is commonly congenital in nature.
Sx include….
Asymptomatic
DOE
Fatigue
Pulmonic stenosis
This valvular disease results from an incompetent pulmonic valve that allows blood to flow back into the right ventricle from the pulmonary artery.
Sx include
RHF
Emboli
Pulmonary HTN
Pulmonic Valve Regurgitation
What are THREE common causes of pulmonic regurgitation?
Pulmonary HTN
Pulmonary Artery Dilation
Infectious Endocarditis
What may be a common EKG finding in a patient with pulmonic valve regurgitation?
RVH
This valvular disease results in an obstruction between the right atrium and ventricle and is almost always caused by rheumatic infection.
Sx include….
Fatigue
Edema
Mild PND
Tricuspid Valve Stenosis
How is tricuspid valve stenosis medically managed?
Diuretics prior to valvotomy
This valvular disease is commonly caused by right ventricular dilation and results in a back-flow of blood from the right ventricle into the right atrium
Sx include
WORSENING RHF
Tricuspid Valve Regurgitation
What concerning complication should you mpnitor patients with tricuspid valve regurgitation for?
Pulmonary HTN
What are the two most common bacteria that cause infectious endocarditis?
Staph
Strep
When working up a patient for suspected CAD, what is the appropriate stress test in a patient who is low probability?
Intermediate?
Low: Do nothing
Intermediate: Exercise Stress vs Radionuclide
T/F: An echocardiogram should be down in conjunction with a stress test in the evaluation of CAD
True
Is an exercise stress test the appropriate choice for an 85 y.o. who ambulates with a walker?
No, a radionuclide study would be more appropriate
Should you hold a patients CCBs or Beta-blockers if an exercise or dobutamine stress is being preformed?
Why?
Yes, because the patient will not be able to raise their HR enough.
Other than inability to ambulate, what other criteria prevent a patient from preforming an exercise stress test?.
- Abnormal EKG findings
- LBBB
- Baseline ST depression
- WPW
What medications used in a stress test should be avoided in patients with severe asthma/COPD?
Persantine/Adenosine
Which of the cardiac enzymes is the most non-specific however goes up the earliest in an AMI?
Myoglobin
What cardiac enzyme is the most sensitive in an AMI however takes up to 6 hours to reach sensitive levels?
CKMB
This cardiac biomarker can be detected as soon as 2-3 hours in patients with an AMI.
Troponin
What is the appropriate minimal amount of time to rule out an AMI through trending/repeating cardiac enzymes?
12-16 hours
What additional processes/diseases may elevate Troponin levels other then an AMI?
- Shock
- Myocarditis/Pericarditis
- CHF
- Sepsis
- PE
- CKD/ESRD
- Trauma
- BUrns
- CVA
- Rhabdomyolysis
- Extreme Exertion
- Inflammatory State
A patient who presents with the complaint of chest pain without ST changes on EKG however does have elevated cardiac biomarkers would rule in for a _______.
NSTEMI
AS long as a patient diagnosed with a NSTEMI is pain free without EKG changes, is immediate PCI warranted?
No, the goal still remains to get the patient to the PCI lab within 24 hours however there is no benefit seen to immediate catheterization in NSTEMI patients like there is in STEMI patients.
What dose of ASA should NSTEMI patients be given in combination with O2, NTG, and Cardiac Monitoring?
What will the daily dose of ASA be in the next following days?
325 mg PO
Daily dose of 81 mg PO
Are Beta-Blockers withing 24 hours a core measure of treatment in patients with NSTEMI?
What if the EF is <40?
Yes
ACEi or ARB
If Beta-blockers are contraindicated and there is no sign of heart failure then what class of medications is the next appropriate in NSTEMI management?
Non-dihydropyridine CCB (diltiazem/verapamil)
T/F: Coumadin is the anticoagulant of choice in NSTEMI patient treatment while in the hospital
False (Heparin)
What is the primary difference in the treatment of NSTEMI vs STEMI?
Immediate PCI is indicated in STEMI patients whereas PCI is only required within the first 24 hours.
If a PCI lab is not within 90 minutes of your facility, what medications should be given to STEMI patients?
Thrombolytics
After thrombolytics are given should the patient still be transferred to a facility capable of preforming PCI?
YES!
