Cardiology Flashcards
HF stages and classes
AHA stages: A - high risk, no structural disease B - structural disease, no sx C - structural disease and symptoms D - refractory, advanced therapy
NYHA classes:
1: no limitations
2: slight limitations w activity
3: marked limitation w activity
4: sx at rest or no activity possible
Screening for family members w DCM
First degree relatives - echo every 3-5 years
3 generations family history needed
+/- in idiopathic DCM
Initial evaluation of HF
CBC, UA, lytes, lipids, lfts, tsh
EKG
Consider HIV, hemochromatosis
Consider rheum, amyloid, pheo
CXR
TTE - repeat if clinical change
Ischemic eval, viability, MRI
RHC indications in HF
Respiratory distress and questions left after clinical eval
If fluid status or SVR uncertain Low BP Renal dysfunction Pressors Considering advanced therapy
Stage A treatment
Control htn and hl
Lose weight, DM control, stop smoking, stop cardiotoxic shit
Stage B treatment
ACE or ARB BB Statins if ischemia Control BP ICD if 40d after MI and EF <30
No nondihydropyridine CCB if no sx after MI
Stage C treatment (HFrEF)
Sodium restriction
CPAP for OSA
Exercise/cardiac rehab
ACE/ARB
BB
Hydra/nitrate for AA
Spiro (ARB on top of ACE if not tolerated)
Diuretics for volume overload
Dig can decrease hospitalization
AC if AF
No CCB except amlodipine
ICD 40d post MI EF <35
CRT if EF <35 and LBBB w QRS >150, consider if QRS >120
Stage D treatment
Fluid restriction
Inotropic support if there is a goal or if palliative
VADs as transition to definitive therapy or as destination
Transplant
Decompensated HF workup
Consider ischemia w EKG and troponin
BP, nonadherence, AF, PE, CCBs or BBs, EtOH or drugs, DM, thyroid, infection, CV problem
Decompensated HF treatment
Continue GDMT but don’t start BB
Diuretics, UF
Consider vasodilator (ntg to decrease preload, nipride for preload and afterload) for dyspnea
VTE prophylaxis
Fix hyponatremia
F/u 7-14 days
Fixed defect on nuc stress
Scar
Hibernating myocardium
Artifact
Check gated images to compare wall motion
TID
Transient ischemic dilation
Cutoff varies with modality
Poor prognostic sign for epicardial ischemia
Normal MPI with decreased EF or global hypokinesis
Concern for global ischemia - either 3 vessel epicardial disease or micro vascular disease
Can check MBF on PET
Wellens sign
Deep T wave inversions precordial leads - high grade LAD stenosis, high risk of MI
HCM echo diagnosis
Septal thickness >15 mm
