Congestive heart failure guideline

Functional classification( NYHA) Class IV: symptoms at rest Class III: symptoms on less-than-ordinary exertion Class II: On ordinary exertion Class I: only at levels that would limit normal individuals

FRAMINGHAM CRITERIA FOR CONGESTIVE HEART FAILURE

Symptoms and signs of left side heart failure Pulmonary rales Tachycardia Dullness at base (secondary pleural effusions) Cheyne-Stoke respiration Abnormal PMI S3, S4 S3, S4

Symptoms and signs of right side heart failure Jugular vein increased Pleural effusions Congestive hepaomegaly Ascites Peripheral edema

Approach to left side heart faliure

Goals of HF Therapy Improve hemodynamics/ symptoms Reduce remodeling/ prevent cell death Increase survival –Risk factor modification( BP, statins, exercise) –ACE inhibitors,  -blockers –Arrhythmias( Amiodarone, AICD) –Transplantation, heart replacement

Treatment of CHF General rule Bed rest Bed rest Restrict water and salt and record I/O Restrict water and salt and record I/O O2 therapy O2 therapy Preload reduction Afterload reduction Increased contractility Correct etiology and precipitation factor

Treatment of acute heart failure with pulmonary congestion Airway managenent and O2 supply Airway managenent and O2 supply NTG :begin 10~20ug /min and titrate 5~10 ug per 5 minutes NTG :begin 10~20ug /min and titrate 5~10 ug per 5 minutes Nitroprusside :Initial 15ug /min and titrate to effect up to 200 ug /min Nitroprusside :Initial 15ug /min and titrate to effect up to 200 ug /min Morphine sulfate :2~5 mg and titrate to effect Morphine sulfate :2~5 mg and titrate to effect Diuretics : 40~80mg IV initially, double dose if output is unsatisfactory Diuretics : 40~80mg IV initially, double dose if output is unsatisfactory 2 hours later 2 hours later
