Heart Failure Flashcards
An elevated JVP is more suggestive of…?
Right sided heart failure
Pulmonary hypertension can lead to…?
Right sided heart failure
Stages of Management of Left Ventricular Failure
1 - Sit parient upright
2 - Administer 100% O2 through a trauma mask
3 - Establish venous access
(If patient needs opiates, administer IV diamorphine and IV metaclopramide)
4 - Administer IV frusemide 80-100mg
5 - Insert urinary catheter
(Patient with systolic BP >110, with pulmonary oedema and no history of mitral/aortic stenosis, administer IV nitrates)
6 - Continuous positive airway pressure
What is Congestive Cardiac Failure?
A syndrome
Collection of pathologies which result in low cardiac output and fluid retention
Common causes of left sided heart failure?
Ischaemic heart disease
Previous MI
Cardiomyopathy
Valvular disease
Common causes of right sided heart failure?
Secondary to left heart failure
Cor pulmonale
Congenital heart disease
Symptoms of left heart failure?
Dyspnoea on exertion/rest
Orthopnoea (fluid falls to lungs soon lying down)
PND
Pulmonary oedema (sudden dyspnoea, pink frothy sputum)
Signs of left heart failure?
Tachycardia
Fine crepitations
Pleural effusion
Gallop rhythm (S3 + tachycardia)
Signs of left heart failure on CXR?
Cardiomegaly
Bats wing shadows (esp. lower zones)
Interstitial fluid
Symptoms of right heart failure?
Peripheral oedema
Signs of right heart failure?
Ankle/sacral oedema
Elevated JVP
Hepatomegaly
Ascites
Signs of right heart failure on CXR?
Normal
Treatment of CCF due to previous MI or Cardiomyopathies?
Standard Medical Therapy Diuretics ACE Inhibitors Beta Blockers (caution) Spironolactone in severe cases
Digoxin Other vasodilators (nitrates, hydralazine)
Implantable Cardiac Defibrillators
Cardiac Resynchronisation Therapy
Transplantation
Treatment of CCF due to Cor Pulmonale?
Diuretics and oxygen only
Treatment of CCF due to valvular disease?
Ideally surgery
Treatment of CCF due to fast AF?
Digoxin or DC shock
Use of diuretics in CCF?
To excrete retained fluid
Thiazides for mild CCF only
Loops used more commonly
Why are loop diuretics administered alongside ACE inhibitors?
Loop diuretics cause loss of K
ACE inhibitors help retain and normalise K levels
Use of beta blockers in CCF?
Can worsen CCF in short term, but beneficial in long term
Start low, go slow
Initial risks of beta blockers in CCF?
Hypotension
Worsening dyspnoea
Why might ivabradine be used in CCF?
Fast heart rate despite use of beta blockers
Only works when heart is in sinus rhythm
What is the purpose of an ICD?
Detect arrhythmias and deliver a shock to the heart
What is the purpose of CRT and when might it be used?
Only used for prolonged QRS due to unsynchronised contracting of the right and left sides of the heart
Biventricular pacing - forces right and left to contract together
Acute LVF Therapy?
Sit up = Fluid does away from the lungs Oxygen therapy IV furosemide = Combat fluid retention and causes vasodilatation IV diamorphine (not in COPD)
What are the features of heart failure due to diastolic dysfunction?
LV hypertrophy
Lack of cardiomegaly r LV dilation
S4 heart sounds
Impaired left ventricular relaxation, increased end diastolic pressure and normal end-systolic volume are a result of which dysfunction?
Diastolic
Why might diastolic dysfunction occur?
LV hypertrophy
LV stiffness
Impaired LV relaxation
