Heart Failiure Flashcards
Explain 3 compensatory mechanisms when BP falls ?
Activation of baroreceptors
Activation of RAAS
Non osmotic ADH secretion
Symptoms of RHF
JVP increase Tender hepatomegaly Ascites Bipedal edema Interstitial edema Splenomegaly Nocturia Pathological S3 \+ Hepatojugular reflex Weight gain
Symptoms of LHF
Pulmonary wedge pressure increases Pulmonary congestion and edema Rales and crepitus on PE Pathological S3 Quadruple rhythm in severe cases PND Orthopnea Coughing due to pulmonary congestion
How to check if dyspnea on patient is cardiac or pulmonary in origin?
PND is only present of dyspnea is of cardiac origin
What criteria is used in diagnosis of HF?
Framingham criteria
2 major/ 1 major + 2 minor
What are the major criteria of Framingham criteria?
JVP increase(neck vein distention) Acute pulmonary edema Rales and crepitus S3 gallop Reflex (HPJ) + Venous pressure (>16mmHg) PND Circulation time(>25sec) Cardiomyopathy
Minor criteria of Framingham criteria?
Tachycardia, hepatomegaly Night coughs Pleural effusion Pleural edema Vital capacity 1/3 of normal
Most common Etiology of RHF?
Left heart failure
Most common Etiology of acute RHF?
Massive pulmonary embolism
Most common Etiology of Chronic RHF?
COPD
List all the etiology of RHF
COPD Massive pulmonary embolism Left heart failure Pulmonary stenosis Pulmonary regurgitation Tricuspid stenosis Tricuspid regurgitation Congenital heart disease
What are the 2 major types of etiology of LHF
Decreased ejection fraction type(<50%)
Preserved ejection fraction type(>50%)
Chagas disease is caused by what organism?
American trypanosoma
List etiology of LHF(reduced EF type)
Angina, myocardial infarction Hypertension and aortic stenosis Mitral regurgitation, aortic regurgitation ASD, VSD Dilated cardiomyopathy Parasitic infection(Chagas disease)
What parasite can cause reduced EF type of LHF
American trypanosoma(Chagas disease)
