Chronic Heart Failure
Flashcards do conjunto (14)
- 1What is the pathophysiology behind CHF?A cardiac dysfunction that impairs the ability of ventricles to fill or eject blood.
- 2What areas of the heart does it effect?One or both ventricles
- 3What occurs during Systolic Heart Failure.- Impaired ventricular contraction.
- Decreased ejection of blood out of the ventricles. - 4What occurs during Diastolic Heart Failure?- Ventricular hypertrophy.
- Decreased ventricular relaxation -> less blood fills the ventricles. - 5What is ventricular hypertrophy?Thickening of ventricular walls
- 6What is the prevalence of CHF?10% adults >65 years old
1 out of 5 people - 7What are the causes of CHF?- Coronary artery disease
- Chronic heart disease
- Hypertension
- Diabetes
- Obesity
- Alcohol consumption
- Uncontrolled atrial fibrillation - 8What are some factors that can exacerbate CHF?- Poor compliance with management
- Anaemia
- Co-exisiting infections e.g. Pneumonia
- Excess alcohol
- Pulmonary embolism
- Excess salt intake - 9What is the primary care for CHF?Early screening and prevention
- 10What is secondary care for CHF?The prevention of progression AND pharmacotherapy to improve symptoms
- 11What is tertiary care for CHF?- Pharmacotherapy
- Secondary prevention after MI
- Intensive home monitoring to prevent progression and clinical event. - 12What are some symptoms of CHF?- Dyspnea (SOB) with exertion or minimal activity.
- Fatigue
- Oedema - 13What is the sympathetic nervous system response to CHF?Cardiac output maintained via vasoconstriction + increased heart rate.
- 14What is the effect of the sympathetic nervous system response on CHF?Effective in the short term but increase in preload and afterload reduces cardiac output -> further ventricular dysfunction.
