Heartfailure The heart cant provide body enough blood Less pumping power Higher pressure of chamber Slower flow rate of blood What Is Heart Failure? Coronary artery disease Causes What causes heartfailure Compensa- tion reaction Compensationreaction When the heart muscle doesnt contract with enough force, there is less oxygen- rich blood that is pumped throughout the body Types Of Heart Failure Structural heart disease with prior or current symptoms of HF Stage B Refractory HF requiring specialized interven- tions Stage C AHA/ACC Guidelines Stage A StagesofHeartFailure No limitation during ordinary activity Slight limitation by shortness of breath fatigue during moderate exertion or stress Class I Class II Class III Symptoms with minimal exertion that interfere with normal daily activity Inability to carry out any Class IV physical activity Congested lungs Symtoms Rapid or irregular heartbeats Fluid and water retention Dizziness fatigue weakness Symptoms Diagnosis Diagnosis Symptoms Physical exams Assistant examina- tion Medical history Heart failure medications Diabetes kidney disease Medicalhistory Drink alcohol and how much you drink angina high blood pressure heart problems Smoke Cardiac catheterization coronary angiogram AssistantExaminations Echocardiogram EF Cardiac MRI Chest X-ray Blood tests Stress test EKG BNP BNP • BNP is a substance secreted from the heart in response to changes in pressure that occur when heart failure develops and worsens. The level of BNP in the blood increases when heart failure symptoms worsen, and decreases when the heart failure condition is stable. The BNP level in a person with heart failure -- even someone whose condition is stable -- is higher than in a person with normal heart function. EF • A normal EF is generally between 55% and 75%, which means that over half of the blood volume is pumped out of the heart with each
