1
Q

What is heart failure - doctor

A

Heart failure is a condition in which the heart is unable to generate a cardiac output sufficient to meet the demands of the body without increasing diastolic pressure.

Q

NYA Class 1

A

Mild. No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitations, or dyspnoea.

Q

Complications of HF

A
  • pleural effusion
  • acute decompensation of HF
  • acute renal failure/insufficiency
  • sudden cardiac death
  • anaemia
17
Q

Management of acute decompensation of HF

A
  • Furesomide
  • Oxygen
  • ACEi/ARBs
  • nesiritide - vasodilator - if needed
  • beta blocker - if needed
18
Q

Types of acute coronary syndrome

A
  • Unstable angina
  • NSTEMI
  • STEMI
19
Q

Unstable angina criteria

A
  • Chest pain not relieved on rest/with nitrates
  • Troponin normal
  • Normal ECG/transient changes - ST depression
20
Q

Treatment of confirmed unstable angina

A
  • Aspirin 75mg
  • Statin
  • Beta blocker
  • ACEi
  • Cardiac rehabilitation (lifestyle)
21
Q

What is Paroxysmal nocturnal dyspnoea

A

Patients will describe waking up and feeling acutely short of breath, with a cough and wheeze. Symptoms improve over several minutes

22
Q

Causes of chronic HF

A

Ischaemic Heart Disease
Valvular Heart Disease (commonly aortic stenosis)
Hypertension
Arrhythmias (commonly atrial fibrillation)

23
Q

When do you start someone on an aldostesterone antagonist in chronic HF

A

when there is a reduced ejection fraction and symptoms are not controlled with an ACEi and beta blocker.

24
Q

What should patients on diuretics, ACE inhibitors and aldosterone antagonists be monitored for frequently

A

electrolyte imbalances

25
Q

What is cor pulmonale

A

Right sides heart failure due to the increased pressure and resistance in the pulmonary arteries (pulmonary hypertension) results in the right ventricle being unable to effectively pump blood out of the ventricle and into the pulmonary arteries. This leads to back pressure of blood in the right atrium, the vena cava and the systemic venous system.

26
Q

What are the main respiratory causes for cor pulmonale

A 
COPD: most common 
Pulmonary Embolism
Interstitial Lung Disease
Cystic Fibrosis
Primary Pulmonary Hypertension
27
Q

What are the signs of cor pulmonale

A

Hypoxia
Cyanosis
Raised JVP
S3
Murmurs (e.g. pan-systolic in tricuspid regurgitation)
Hepatomegaly due to back pressure in the hepatic vein

28
Q

What is the presentation of someone with cor pulmonale

A
  • Early stages asymptomatic
  • SOB: rest or exertion
  • peripheral oedema
  • syncope
  • chest pain
29
Q

What is the management of cor pulmonale

A
  • Treat underlying cause
  • Treat symptoms
  • LTOT
  • Prognosis is poor unless treatment of underlying acuse
30
Q

What are the acute signs of right ventricular failure

A
  • Raised JVP
  • hepatojugular reflux sign
  • Hepatomegaly
31
Q

What are the chronic signs of right ventricular failure

A
  • Pedal oedema
  • Sacral oedema
  • Ascites
32
Q

What are the signs of left ventricular failure

A
  • Pulmonary oedema
  • Poor peripheral perfusion
  • Tachypnoea
  • Tachycardia
33
Q

What are the acute causes of right ventricular failure

A
  • MI
  • PE
  • Infective endocarditis
34
Q

What are the chronic causes of right ventricular failure

A
  • Left ventricular failure

- Cor pulmonale

35
Q

What are the acute causes of left ventricular failure

A
  • MI

- Infective endocarditis

36
Q

What are the chronic causes of left ventricular failure

A
  • Ischaemic cardiomyopathy
  • Hypertensive cardiomyopathy
  • Valvular heart disease
37
Q

What is the conservative management of congestive cardiac failure

A
  • stop smoking

- Long term O2 therapy if cor pulmoanle

38
Q

What is the medical management of congestive cardiac failure

A
  • Beta blocker
  • ACEi
  • Treat underlying causes e.g. HTN, Afib
39
Q

What is the surgical management of congestive cardiac failure

A

Left ventricular assist devices or transplant
