How might you use Nitroglycerin in a patient with angina (stable/unstable)?
- Rescue prescription in case angina suddenly worsens
- Can be used during stress testing
- A patient with unstable angina that is not resolving can take up to 3 doses of 0.4mg Nitro (spaced 5 minutes apart) to relieve chest pain.
If no relief–> ER
How might we distinguish between aortic stenosis and a carotid bruit?
Carotid bruit will be heard with the bell.
AS will get louder as you auscultate closer to the heart.
AS will change based on dynamic auscultation
What are some vagal maneuvers and what can they treat?
to treat: PSVT, atrial tachycardia, sinus tachycardia
Valsalva with leg lift is most effective maneuver
carotid sinus massage, leg lift, ice also may help
Elevated homocysteine increases risk for:
Tx?
Increased risk for CAD
Tx: methylated folate, B12, B Complex
Elevated fibrinogen may indicate:
Tx?
May indicate: hyperviscosity, plaque formation, thrombi, endothelial injury
Tx: ginseng, bromelain, E-complex, Licorice, garlic, curcurmin, ginger, Boswelia, Nattokinase, Bioflavanoids
Elevated Lp(a) may indicate:
May indicate carotid atherosclerosis and increased 5-year mortality from atherosclerosis
Low bleeding time may indicate:
Tx?
Increased clot risk
Tx: fish oils, warfarin
High CRP may indicate:
coronary artery inflammation
Which lipids tend to be high in diabetes?
TGs
LP-PLA2 is also a useful marker in gauging risk among diabetics
Homocysteine will also be elevated in DM
What is Dr. Millers basic protocol for hyperlipidemia?
- Niacin
- RYR with CoQ10 and plant sterols
- Garlic, pantethine, guggul resin, EPA/DHA, Policosanol
Which HDL is most protective? Which HDL type is least protective?
HDL 2 is most protective
HDL 3 is least protective
What type of lipidemia presents with: \+++high cylomicrons WNL choelsterol HDL WNL \+++high Triglycerides Normal risk profile
type I
Treatment: LF, NA
What type of lipidemia presents with: \+++ high LDL \+++high cholesterol normal or slightly high Triglycerides \+++ increased risk
Type II
Treatmetn: LC, LF, IHN
What type of lipidemia presents with: IDL mildly elevated \+++ elevated cholesterol \+++ elevated Triglycerides \+++ elevated risk
type III
Tx: LC, LCHO, IHN, GMF
What type of lipidemia presents with: \+++ high VLDL - low HDL Normal or mildly high Cholesterol \+++ high TGs \++ increased risk
Type IV
Tx; LW, LCHO, NA, IHN, GMF
What type of lipidemia presents with: WNL or + elevated Cholesterol \+ elevated Chylomicrons \+elevated VLDL low HDL \+++ elevated TGs risk unknown
Type V
Tx: LW, LF, NA, IHN, GMF
Which cardiac marker might you see elevated 4-6 hours after MI until about 3 days?
CK-M, CK-MB
Which cardiac marker might be elevated 1-2 hours after MI until about 20hrs?
Myoglobin
Which cardiac marker might be elevated 2 hours after MI until 10 days?
troponin I (heart specific)
Which cardiac marker might be elevated earliest and last longest?
troponin T (non-heart specific)
EKG shows jagged baseline, some saw-toothed patterns before QRS complexes. No visible p-wave and an irregular rhythm.
Dx?
Atrial Fibrillation
What is the CHADS score and what does it indicate?
C: CHF, 1 point H: HTN, 1 point A: Age >75, 1 point D: DM, 1 point S: Stroke/TIA history, 2points
Score of 0: Aspirin 81-325mg qd indicated
1: Aspiring qd or Coumadin indicated
2+: Coumadin indicated (target INR 2-3)
Treatment goals for A-fib:
slow heart rate, prevent stroke/thrombus formation, cardioversion back to normal rhythm, prevent recurrences
What drugs are indicated for cardioversion?
Amiodarone (most effective, least side- effects)
Propafenone (overall safest)
Digoxin (does not convert, just slows ventricular rhythm.
Which naturopathic remedy can slow heart rhythm in Atrial fib and is much less toxic than Amiodarone?
Iodine! (SSKI or Lugol’s)
Watch for toxicity: acne, diarrhea, N/V, fatigue, numbness, fever, confusion, tarry stool
How would you dose Warfarin?
Dosing: 1, 2, 2.5, 3, 4, 5, 6, 7.5 mg tabs available
Start at 2-5mg PO/IV qd #2-4 days (usually start at 5mg)
Adjust dose q4-5 days based on INR (target is 2-3)
ie. if INR is between 1/1.5, increase dose by 20%
note: Amiodarone potentiates Warfarin
How does Ach treat tachycardias?
Ach is the only neurotransmitter used in the motor system of the somatic nervous system.
While it stimulates contraction of skeletal muscle, it inhibits contraction of cardiac muscle.
