Q

if have viral myocarditis, the patient play sports?

A

No, refer to cardiologist for further management

sudden death with continued strenuous aerobic exercise in myocarditis (exercise allows virus to replicate = worsens disease = ventricular ectopy)

cardiologist will follow lifelong

if treadmill stress test and ECG are normal (wks-months)

Q

acute coronary syndrome (ACS) sx’s

A

GET MORE HISTORY! then send to cardiac care facility for management

  • since chest pain affects every organ, want MORE history and not imaging
  • Worsening in the frequency, intensity, duration, and timing (ie, nocturnal pain, rest pain) of prior anginal or anginal equivalent symptoms
  • New-onset shortness of breath, nausea, sweating, extreme fatigue in a patient with a known history of CVD
  • Onset of typical anginal symptoms in a patient without a history of cardiovascular disease
  • New findings on physical exam of murmur (or worsening of a previously noted murmur), hypotension, diaphoresis, rales or pulmonary edema

Q

after completing a thorough hx/ E for chest pain…

A

Evaluate need for emergent care: if think ACS, chew an aspirin & go to ED.

Q

Gold standard/first line to diagnose unstable angina:

A

on ECG - looking for downsloping or horizontal ST depression
* Stress test/exercise tolerance test within 72 hrs of angina if EKG inconclusive
* want to reproduce the stress in the heart /dyspnea on exertion under controlled situations WHEN THEY ARE NOT HAVING CHEST PAINS
* less effective in women bc women have non obstructive or single vessel disease
*

A

*classify pt as either reduced/systolic HF or preserved/diastolic HF

  • systolic/R: BB, ACE-i/Arb/ARNI, thiazide/loop, aldosterone antagonist
    • monitor renal, Cr, KCl
    • hydralazine w/ isosorbide
    • ivabradine
    • digoxin
    • ICD (if EF< 35%)
  • diastolic/P: lifestyle, diuretics, treat comorbidities (DM, HTN, CAD)
85
Q

Stage D HF management

A

consider LVAD/transplant

palliative care

86
Q

when to refer for heart failure?

A
  • sx’s refractory to standard therapies
  • new stable arrhythmias
  • new coronary ishcemia on EKG
  • ALL young pt’s w/ dilated cardiomyopathy or worsening sx’s
87
Q

when to hospitalize HF?*

A
  • new onset HF with signs of congestion/fluid overload
  • suspect infarction or ischemia
  • pulmonary edema (pink frothy sputum)
  • O2 < 90%
  • unstable pts
  • ACS/MI
  • new arrhythmia w/ hemodynamic instability
88
Q

Peripheral artery disease (PAD) screening

A
  • All over 65
  • all over 50 with hx of smoking or diabetes
  • all with suspected PAD sx’s + non healing wounds
89
Q

PAD hallmark sign and presentation *

A
  • discomfort with activity “tiredness”, “giving way”, “soreness” “pain”
  • hallmark: intermittent claudication
    • tightening, cramping pain from exercise and alleviated by rest
    • calf most common, thigh, butt (iliac artery obstruction/Leriche syndrome)
  • severe: pain @ rest/awaken at night (alleviated by gravity)
90
Q

*PAD exam

A
  • distal hairloss
  • shiny skin
  • absent femoral pulses/femoral bruit
  • muscle atrophy
  • advanced:
    • dependent rubor (pale with elevate for 30 secs, then when dependent, deep red ensues
      • longer it takes for rubber to get = worse ischemia
      • skin ulcers
91
Q

PAD initial diagnostic & for whom?

A
  • resting arterial brachial index (ABI): portable doppler + sphygmomanometer cuff
  • used in pts with 1 or more of:
    • exertion leg sx’s
    • non healing lower extremity wounds
    • hx with PAD in 65 ys +
    • sx in pt 50 yrs + with smoking hx or diabetes
92
Q

ABI interpretation and scores

A
  • ABI lower in affected extremity
  • measure brachial artery with dorsals pedis and posterior tibial arteries
  • <0.9: PAD
  • 0.75 - 0.5: claudication
  • < 0.5: rest with pain and/or tissue loss
  • 1-1.3: normal
  • >1.4: calcified arteries → further assess with toe brachial index
93
Q

AAA screening

A

1 time in men 65-75 who ever smoked

94
Q

PAD treatment/management

A
  • stable claudication
    • exercise, no smoking, HTN/HLD/DM tx, compression stockings if ABI > 0.8
    • train walk to point of pain the rest til pain subsides
  • podiatry consult
  • ALL pts get ASA or placid, ACE/ARB, cilostazol (improve walking distance)
    • NO b complex vitamin
  • if severe ischemia: arteriography (diagnostic), then angioplasty or surgery = refer to er
95
Q

PAD complications

A
  • AAA!!!
  • non healing wounds/ulcers
  • peripheral neuropathy
  • renal artery stenosis
  • infection
96
Q

pericarditis can be from

A
  • bacterial or viral infection
  • autoimmune
  • w/ MI
  • isoniazid or hydralazine
  • malignancy
97
Q

pericarditis clinical presentation

A
  • sudden onset sharp retrosternal chest pain radiates jaw neck, pleuritic in nature
  • chest pain worse supine, relieved sitting up & leaning forward; worse with inspri/expiration
  • pericardial friction rub 85% while sitting, leaning forward
    • RUB DOES NOT CHANGE WITH INSPIRATION/EXPIRATION
98
Q

pericarditis diagnostic criteria

A

2 or more:

  • sharp pleuritic chest pain
  • diffuse ST elevation
  • pericardial friction rub
  • new or worse pericardial effusion on ECHO (elevated inflammatory markers)
99
Q

pericarditis workup

A
  • EKG: diffuse ST elevation
  • Send to ED
  • CXR (size, r/o pulmonary etiologies)
  • ECHO (normal or pericardial effusion)
  • CBC w/ diff, ESR/CRP (eleva) troponin (elv)
100
Q

*pericarditis treatment

A
  • low risk: no large effusion, stable, no fever → outpatient
  • NSAIDs (ibuprofen or indomethacin) MAX dose then titrate down over 3-4 weeks
  • f/u regularly recheck inflammatory markers and sx’s
  • if no improvement in 1 wk, get hospitalized and refer to cardiology for further eval
