Unstable angina vs NSTEMI vs STEMI
UA: no trops, no ST #
NSTEMI: trops, no ST #
STEMI: trops, ST #
If heart failure and EF < 35% but not class IV, give___
AICD
Progression of heart failure management
class I beta-blockers + ACE-i/ARB –> class II Loop diuretics –> class III Isosorbide dinitrate-hydralazine + spironolactone –> AICDif not class IV and EF <35%
Management of CHF exacerbation
Lasix Morphine Nitrates O2 Position
Potential causes of CHF exacerbation
MI
med/diet non-compliance
Pathologic murmurs (2)
systolic grade 3 or murmur
any diastolic murmur
Always get an ECHO
Mitral stenosis: auscultation findings
left atrial stretch and fluid in the lungs –> afib and or CHF sxs
Findings: rumbling diastolic murmur with an opening snap heard best at Apex
NOTE: often from rheumatic heart disease and occurs in younger people
Mitral stenosis: TX
Initial: balloon valvuloplasty (through left heart cath) as valve is not calcified as in other valvular d/os
late: replacement
Aortic regurgitation: auscultation findings
Aortic valve insufficiency –> left venticular dilation
Findings: rumbling diastolic murmur heard at base
Causes of aortic insuffiency
acute: aortic dissection, infection, and infarction
Presentation of aortic insufficiency
acute: cardiogenic shock, flash pulmonary edema, CP
chronic: CHF, CP
Aortic insufficiency: TX
replacement
Aortic stenosis: auscultation findings
left ventricular dilation –> CHF as seen also in aortic insufficiency
Findings: systolic murmur heard best at base in crescendo-decrescendo quality
Causes of AS
ATHEROSCLEROSIS
Mitral insufficiency: auscultation findings
left atrial dilation –> afib and CHF sxs
Findings: holosystolic murmur heard best at apex
Hypertrophic obstructive cardiomyopathy: auscultation findings
systolic murmur like AS, but more blood with physical exam maneuvers in heart makes better
SOB or syncope with exertion in a young athlete
HCOM
HOCM: TX
beta-blockade (want heart to be slow enough for long enough diastole)
AVOID decreases in pre-lod (dehydration, exercise)
Mitral valve prolapse: auscultation findings
Findings: systolic murmur heard at apex, better with physical exam maneuvers that increase preload (leg left and squatting)
MVP: TX
beta-blockade
avoid dehydration
Systolic vs diastolic HF
systolic: Echo shows dilated LV, caused by viruses, alcohol, pregnancy, ischemia, TX with beta-bloackade, ACE-is, and diuretics
Diastolic: Echo shows concentric LVH, caused by hypertension or material restriction from amyloid/sarcoid/hemochromatosis, TX with beta-blockade or CCBs (verapimil or dilt), avoidance of HTN and dyhydration
Diastolic HF with neuropathy =
amyloidosis
Dx: fat pad/gingiva bx
Diastolic HF with pulmonary disease =
sarcoid
Dx: cardiac MRI and endomyocardial bx
Diastolic HF with cirrhosis and bronze DM =
hemachromatosis
Dx: ferritin and genetic testing
Types of causes of pericardial disease (4)
(1) infection (remember TB)
(2) autoimmune (RA, dresslers, uremia)
(3) trauma (penetrating and blunt, dissection)
(4) cancer (breast, lung, lymphoma, esophageal)
Best TX for pericarditis
NSAIDs and colchicine
NOTE: can use steroids, but this makes recurrence more likely
Best imaging modality for pericarditis
MRI
NOTE: EKG used though
Findings on EKG for pericaditis
PRsegment depression and diffuse ST segment elevation
indications for statin therapy
vascular disease (MI, PVD, CAS)
LDL > 190
LDL btw 70-189 + 40-75yo + DM
LDL btw 70-189 + 40-75yo + high ASCVD
syncope considerations
W vasovagal Orthostatic hypotension Mechanical cardiac (can cause SCD) Arrythmogenic cardiac (can cause SCD) Neurologic Psych Electrolytes
High-intensity statins
atrovastatin 40 or 80
ruvastatin 20 or 40
DO NOT use with fibrates
Moderate-intensity statins
atorvastatin 10 or 20
ruvastatin 5 or 10
NOTE: also for people who need statins but contraindicated against high-intensity (GI upset, age > 75yo, liver or renal dysfxn, past myositis or hepatitis with high dose statin)
Causes of secondary HTN
Consider in pts < 35yo with HTN or those with refractory HTN
Hypercalcemia Hyperthyroid Hyperaldosteronism Aortic coarctation Renovascular Pheo Cushings OSA
Initial basic testing for patient diagnosed with HTN (4)
UA, CMP (need initial LFTs), lipid profile, baseline ECG
Aspirin + ____ improves survival in pts following NSTEMI
P2y12 receptor blocer (clopidogrel, prasugrel, or ticagrelor)
