what is the most common cause of heart failure? specifically left sided? right sided?
-MC is CAD (coronary artery disease)
-L sided: CAD & HTN
-R sided: L sided HF & pulmonary dz
decreased ejection fraction, thin ventricular walls, dilated LV chamber, and an S3 gallop (filling of
dilated ventricle) is associated with systolic or diastolic heart failure?
systolic (MC form of CHF)
*(the sound is actually heard in the diastole though)
-memory trick: "sys-to-lic" 3 consonants = S3
normal ejection fraction, thick ventricular walls, narrowed LV chamber, and an S4 gallop (atrial
contraction into a stiff ventricle) is associated with systolic or diastolic heart failure?
diastolic
-memory trick: "di-a-sto-lic" 4 consonants = S4
what are the causes of systolic vs diastolic heart failure?
-systolic: post MI, dilated cardiomyopathy, myocarditis
-diastolic: HTN, LVH, elderly, valvular heart dz, hypertrophic or restrictive cardiomyopathy,
constrictive pericarditis
when the metabolic demands of the body exceed normal cardiac function (d/t thyrotoxicosis, wet
beriberi, severe anemia, AV shunting, Paget's disease of the bone) this is termed ________ heart
failure
high-output
*fairly uncommon
-low-output HF is just d/t problem w/ myocardial contraction, ischemia, or chronic HTN
what will the FEV1 and FEV1/FVC ratio of pts w/ intermittent, mild, moderate, vs severe asthma
be?
-intermittent: FEV1 > 80% predicted, FEV1/FVC nml
-mild: FEV1 ≥ 80% predicted, FEV1/FVC nml
-moderate: FEV1 60-80% predicted, FEV1/FVC reduced by 5%
-severe: FEV1 <60% predicted, FEV1/FVC reduced >5%
,what are the daily treatment recommendations for intermittent, mild, moderate, and severe
asthma control?
-intermittent: SABA prn
-mild: SABA prn + low dose ICS daily
-mod: low dose ICS + LABA OR med dose ICS +/- LTRA
-severe: high dose ICS + LABA +/- Omalizumab
remember all forms of asthma need a rescue inhaler/SABA to use prn
what is the only genetic disease linked with COPD?
alpha-1 antitrypsin deficiency (it normally protects elastin in lungs from damage by WBCs)- seen in
younger pts <40y
abnormal, permanent enlargement of the terminal airspaces, loss of elastic recoil, increased
compliance, and increased air trapping d/t obstruction
COPD- emphysema
chronic bronchitis COPD is diagnosed after ____ months total of productive cough in ___
consecutive years
≥3 mos total x 2 consecutive years
which type of COPD has severe V/Q mismatch, severe hypoxemia, and hypercapnia that can cause
respiratory acidosis? this is also strongly associated with multifocal atrial tachycardia (MAT), cor
pulmonale and eventual R HF
chronic bronchitis
PFTs (gold std) for diagnosing COPD will show a FEV1/FVC ratio of <____% and increased _______
FEV1/FVC of <70%
inc TLC, RV (inc lung volumes from hyperinflation)
what can be seen on CXR/CT of a pt w/ emphysema COPD?
hyperinflation (flattened diaphragm, inc AP diameter, dec vascular markings, +/- bullae)
how is COPD tx'd long term?
-smoking cessation!
bronchodilators:
-anticholinergics 1st line (tiotropium, ipratropium) CI: BPH, glaucoma
-B2 agonists (albuterol, terbutaline, salmeterol)
-theophylline- only for refractory cases bc narrow TI
corticosteroids- added to a LABA
oxygen- only therapy shown to dec mortality BUT only prescribe if 1. cor pulmonale 2. O2 sat <88%
3. PaO2 <55mmHg
when are antibiotics indicated for COPD chronic bronchitis exacerbations?
,1. inc sputum
2. change in sputum quality
3. CXR evidence of infxn
in tx of acute exacerbation of chronic bronchitis COPD, at what FEV1 levels should
1. only a short acting bronchodilator (SABA- albuterol, terbutaline) be used?
2. + a long acting bronchodilator (anticholinergics like tio/ipratropium or LABAs like salmeterol)?
3. + pulmonary rehab or steroids if inc exacerbations?
4. + O2 therapy?
FEV1 of:
1. SABA @ ≥80%
2. SABA + anticholinergics/LABA @ 50-79%
3. SABA + anticholinergics/LABA + pulmonary rehab and/or steroids @ 30-50%
4. SABA + anticholinergics/LABA + pulmonary rehab and/or steroids + oxygen @ <30% -OR- cor
pulmonale, respiratory failure, or HF
dx/tx? a (+/- productive) cough lasting 1-3 weeks after a recent URI with a nml CXR?
-dx: acute bronchitis
-tx: supportive (fluids, rest, +/- bronchodilators, +/- antitussives in adults)
*abx not helpful bc usually caused by adenovirus!
