Definition of Heart Failure |
*complex clinical syndrome *result in structural or functioning impairedment *of ventricular filling or ejection of blood *presenting the end-stage of cardiac disease |
|
|
why heart failure happen? |
Heart is not pumping effectively enough to meet rhe metabolic requirements of the tissue for Oxygen & substrates |
|
|
Cause of HF |
1)impaired Cardiac Function 2)Excess work demand |
|
|
Cause in HF - >impaired cardiac function |
1)Myocardial disease (coronary insufficiency - myocardial infarction /ischemia) 2)Valvular heart disease(stenotic/regurgitation) 3)Constrictive pericarditis 4)Congenital Heart disease |
|
|
Cause HF->Excess work demands |
1)Increase pressure work(systemic hypertension /pulmonary hypertension) 2)Increase volume work(excessive iv perfusion) 3)increase perfusion work(Thyrotoxicosis/anemia) |
|
|
Typical symptom of HF!? |
1)Breathlessness (dyspnoea, orthopnoea, Paroxysmal noctural dyspnoea) 2)Fatigue 3)Ankle swelling |
|
|
Typical signs of Heart Failure |
*Tachycardia *Tachpnoea *Pleura effusion *Raised JVP *Peripheral oedema *Hepatomegaly |
|
|
Sign of Failing Heart |
*Cardiomegaly *3rd & 4th heart sound *cardiac murmur *Abnormal echocardiogram *increase natriuretic peptide concentration |
|
|
Congestive Heart Failure |
*Heart failure with evidence of congestion eg:sodium & water retention *Decrease heart function that accompanied by build up of fluid in the lungs & elsewhere |
|
|
Functio of Angiotensin II |
*increase AVP *Vasoconstriction *increase aldosterone *Mesangial contraction *Efferent Constriction *CNS dypsogenia *Na+ retention *vessel hypertrophy *myocardial hypertrophy *Increased NE release |
|
