Heart Failure Flashcards
Is heart failure more common in men or women
Men
What are the three types of heart failure
HFrEF - L ventricular systolic dysfunction
HFmrEF - heart failure w mildly reduced LV function
HFpEF - heart failure w preserved ejection fraction
Most common cause of heart failure
Coronary artery disease
Heart failure causes
Coronary artery disease
Hypertension
Cardiomyopathy
Valvular heart disease
Factors leading to heart decompensation
Cardiac arrhythmias
Hypertension
Anaemia
Infection
Heart failure symptoms
Shortness of breath
Ankle oedema
Fatigue
Heart failure signs
Cool skin
Peripheral cyanosis
Basal crackled
Incr JVP
Angle swelling
Ascites
Tachycardia
Sweating
3rd heart sound
Alternating pulse
How can heart failure present on an ECG
Inferior Q waves
Anterior T wave
Ectopics
L bundle branch block
What triggers myocardial cells to release brain natriuretic peptide
Raised left atrial pressure
What does a brain natriuretic peptide level >100pg/ml indicate
Heart disease is likely cause of Dyspnoea and fluid retention
What does brain natriuretic peptide do
Promotes natriuresis
Promotes vasodilation
Inhibits ADH release
inhibits aldosterone release
What diagnostic tests are used in all patients for heart failure diagnosis
Brain natriuretic peptide level
ECG
echocardiogram
Chest x ray
Blood test for comorbidities
How does sympathoadrenal activation increase contractile function
Increase inotrophic state
How does renin angiotensin activation increase contractile function
Increase myocardial mass
How do beta blockers cause ventricular dilation to increase contractile function
Redistribute venous flow
