Q

why have shortness of breath: left side

A

difficulty of pumping/filling-> back pressure goes into pulmonary circulation-> liquid seeps into alveoli-> alveolar edema (pulmonary edema)

  • high pulmonary venous pressure
  • see narrow pulse pressure

Q

why have shortness of breath: what happens on right side

A

back pressure goes-> pulmonary artery

  • high pulmonary artery pressure
  • get jugular-venous distention
  • can go to liver-> ascites
  • edema

Q

low circulation to kidneys results in

A

increase RAA-> salt and water retention, plasma volume expansion, and increased preload

Q

how to we stage heart failure

A
  • Stage A: at risk of CHF (have diabetes, alcoholics)
  • Stage B: asymptomatic structural disease (thinning wall or thickening wall)
  • StageC: previous/current symptoms
  • Stage D: refractory symptoms

Q

class I classifications

A

no symptoms and no limitations to ordinary physical activity

20
Q

class II

A

mild symptoms to ordinary physical activities

21
Q

class III

A

marked symptoms with less than usual activity, comfortable at rest

22
Q

class IV

A

severe limitations and symptoms at rest. Bed bound patient

23
Q

steps in diagnosis of CHF

A
  1. clinical exam
  2. ECG
  3. chest film
  4. BNP
  5. echocardiography
24
Q

what to look for on CXR

A
  • enlargement of heart base

- congested lungs

25
big heart is
inefficient heart
26
BNP
comes from heart - released from wall tension - enlarged heart-> if increased pressure or volume overload----> release BNP - normal BNP <100
27
what can you see on echo
``` chamber sizes presence and severity of LV systolic dysfunction valve lesions regional LV function assessment LV diastolic function Valvular abnormalities Pericardial diseases RV abnormalities ```
28
normal EF
55-65% | LV EDV- LV ESV)/ (LV EDV
29
hyperdynamic circulation
70-90% EF
30
what happens when someone is diagnosed with CHF
-natural progression
31
treatment of CHF
- diet: low sodium restriction, 2gm or less - daily weight: check everyday (morning) - vaccinations (drugs): influenza and pneumococcus) - limit how much fluid they drink in a day: 1-1.5 liters
32
drugs that improve symptoms for CHF
improve symptoms: diuretics digoxin: to strengthen heart contractility
33
most common drugs to treat CHF
diuretics, beta-blockers and ACE inhibitors Spironolactone Devices
34
drugs that improve symptoms/prognosis
improve symptoms and prognosis - ACE inhibitors/ARB's - beta-blockers - hydralazine/isosorbide - spironolactone - devices
35
cardiac resynchronization
improves LV EF improves symptoms Reduces function MR Indications: EF 120ms
36
advanced therapies
1. chronic inotropic support (first option, if fails, go to 2) - dobutamine - milrinone 2. LV assist devices (LVAD): helps heart to squeeze - Bridge therapy - destination therapy 3. Heart transplantation (last option)
37
acute decompensated CHF
1. don't follow diet - drink too much fluid - get volume overload 2. don't take medicine 3. progression of disease itself: chronic hypertension
38
treatment of acute CHF
1. Diuretics: reduced volume overload 2. Vasodilators: decrease preload and afterload, ACE inhibitors, beta-blockers 3. Inotropes: augment contractility (stage D patients)
39
reasons for acute CHF and treatment
1. address precipitating causes - correct myocardial ischemia - remove offending medications - treat arrhythmias - control elevated BP 2. Patient education
40
heart failure with preserved LV EF (diastolic heart failure)
increased LV filling pressure due to abnormalities in LV relaxation and compliance -elderly, history of HTN, CAD common
41
treatment heart failure with preserved LV EF
``` control BP diet drugs maintain sinus rhythm Diuretics Relieve MI ```
42
larger heart is
NOT stronger heart | -weak
43
chest pain is symptoms of
MI or heart attack
44
first line drugs to improve symptoms in CHF
diuretics
45
What is seen on Chest radiograph
``` Cardiomegaly Vascular engorgement Cephalization Kerley B lines Pleural effusion Enlarged main PA ``` Many may be absent in chronic compensated CHF
