1 Congestive heart failure
Ivan Cerovečki Mentor: A. Žmegač Horvat

2 Elementary notions Cardiac output Peripheral circulation Preload
Afterload

3 Definition of CHF Complex syndrome Impaired function of the heart
Compromised peripheral perfusion

4 Epidemiology Prevalence in Europe: 2 % Prevalence > 65 yrs: 10 %
1st year mortality: 30 – 40 % 5 year mortality: 60 – 70 %

5 Clinical characteristics
Acute heart failure Chronic heart failure

6 Clinical characteristics
Left heart failure Right heart failure Biventricular (congestive) heart failure

7 Aetiology Cardiac pathology Ischaemic heart disease
Hypertensive heart disease Cardiomyopathy Valvular heart disease Congenital heart disease Pericardial disease

8 Aetiology Extracardiac pathology Pulmonary disease: pulmonary embolism
Endocrine and metabolic disease Infective disease Toxic substances: alcohol

9 Pathophysiology Sympathetic activation Increased heart rate
Increased myocardial contractility Venous vasoconstriction Arteriolar vasoconstriction

10 Pathophysiology RAAS system Arteriolar vasoconstriction
Fluid retention

11 Pathophysiology Natriuretic peptides Diuretic effect
Natriuretic effect Hypotensive effect

12 Pathophysiology Ventricular dilatation
Increase in metabolic requirements

13 Clinical features Common symptoms Fatigue Dyspnoea Palpitations
Weight gain

14 Clinical features Left heart failure Paroxysmal nocturnal dyspnoea
Orthopnoea Basal lung crackles Presence of the third heart sound

15 Clinical features Right heart failure Jugular venous distension
Hepatomegaly Peripheral oedema

16 Diagnostics Chest X-ray ECG Blood tests Echocardiography
Natriuretic peptide

17 Treatment Vasodilator therapy ACE inhibitors
Angiotensin II receptor antagonists Nitrates Hydralazine

18 Treatment β – blockers Metoprolol Bisoprolol Carvedilol

19 Treatment Diuretics Loop diuretics Thiazide diuretics
Potassium–sparing diuretics

20 Treatment Digoxin Dopamine Dobutamine Antiarrhythmic drugs

21 Treatment Revascularization Biventricular pacemaker
Cardiac transplantation
