Congestive Heart Failure: What your patients need to know. Lisa M. Kappers, RN, BSN Alverno College MSN Program Patient Care Coordinator – Infusion Therapy Center, WFSI – All Saints
Tutorial Instructions • Use the buttons at the bottom of each slide to navigate through the tutorial or follow the special instructions on certain slides. • The “Home” button will bring you back to the beginning.
Tutorial Outcomes • At the end of this tutorial you will be able to: • Teach your patients about the pathophysiology of CHF. • Teach your patients about the importance of a low sodium diet. • Teach your patients how to “live” with CHF.
In order to complete this tutorial: • You should know the basic pathophysiology of normal cardiac function and normal respiratory function. If you need to review, the links below will take you to tutorials on: • Path of blood flow Cardiac Cycle Blood pressure Respiratory System • To return from these tutorials, click the back button on your browser.
Let’s review the basics. • Which side of the heart pumps blood to the lungs? • Right • Left
Great Job! • The right side of the heart pumps blood to the lungs. • Click on our friend to move forward.
Sorry. • Remember, the left side of the heart pumps blood to the peripheral circulatory system. • Click on our friend to try again.
Which part of the respiratory system is directly responsible for gas exchange? • A. Trachea • B. Larynx • C. Alveoli
Try Again. • The trachea is part of the lower airway but is not directly responsible for gas exchange. Click the duck to try again.
Try Again. • The larynx is responsible for air flow in and out of the lungs as it is a part of the upper airway. It is not responsible for gas exchange. • Click the gator to try again.
Great Job! • The alveoli are thin sacs at the end of the bronchioles which are directly responsible for gas exchange.
Now that we’ve reviewed the basics, let’s talk about CHF. • Remember, the basics are essential in order to complete this tutorial. If you need to review, return to the provided links at the beginning of the tutorial.
Let’s define congestive heart failure. • Heart failure is defined by the ACC/AHA as a disorder where the ventricle is prohibited from filling with or ejecting blood (2005). There are many different clinical signs of heart failure.
Right-Sided Heart Failure • Right sided heart failure occurs when the heart can not move the blood from the periphery into the pulmonary system. This causes blood to back up into the peripheral venous system. • (Porth, 2004)
What symptoms are caused by right-sided heart failure? • Peripheral edema • Dyspnea • Ascites • Hypoxia • Anorexia
You are correct!When the right side of the heart can not move blood from the peripheral system to the pulmonary system, peripheral edema occurs. • Click here to pick another symptom Click here to move forward
Dyspnea is not a symptom of right-sided heart failure. Click here to return to question
In right sided heart failure, the blood can not move from the peripheral system to the pulmonary system. This does not cause hypoxia. • Click here to return to question
Good job!When blood can not be moved from the peripheral system to the pulmonary system, fluid builds up in the abdominal cavity causing ascites. • Click to return to question Click to move forward
Excellent!Fluid in the abdomen can push on the organs causing nausea and anorexia. • Click to return to question • Click to move forward
Left-Sided Heart Failure • Left-sided heart failure occurs when the blood from the pulmonary system can not be pumped into the peripheral system. This causes the blood to back up into the pulmonary vasculature. • (Porth, 2004)
What symptoms would you observe with left-sided heart failure? • Hypoxia • Dependent edema • Cough with frothy sputum • Orthopnea • Jugular vein distention
Fabulous!! • Hypoxia occurs due to the pulmonary congestion caused by left-sided heart failure. Click here to return to questionClick here to move forward
Oops, sorry. • Dependent edema occurs when the blood from the peripheral vasculature can not move forward during right-sided heart failure. Click here to return to question
Great job! • The cough occurs due to the congestion in the pulmonary vasculature. Click here to return to question Click here to move forward
Great thinking! • Orthopnea occurs when the patient is reclined and the blood from the peripheral vasculature settles in the pulmonary system. Click here to return to question Click here to move forward
Let’s think about this. • Jugular vein distention occurs when blood backs up in the peripheral vasculature. This happens during severe right-sided heart failure. Click here to return to the question
Chronic Heart Failure • Chronic heart failure is a combination of right and left heart failure. The right and left ventricles must maintain an equal output. Persistent left sided failure can lead to right sided failure. (Porth, 2004)
Hypertension • There are two types of hypertension: primary and secondary. • Primary hypertension accounts for 90 – 95% of all cases and does not result from another disease process. • Secondary hypertension is the direct cause of a primary disease process such as renal disease. • (Porth, 2004)
Uncontrolled hypertension increases the workload of the left ventricle by increasing the pressure against which the heart must pump. The left ventricle hypertrophies or thickens, decreasing ejection fraction and putting the patient at risk for CHF. • (Porth, 2004)
Hypertension is a risk factor for all major cardiovascular disorders such as atherosclerosis, stroke, heart failure, coronary artery disease, and peripheral artery disease. • (Porth, 2004)
Atherosclerosis and Coronary Artery Disease • Atherosclerosis is defined as fatty lesions developing in the intimal lining of the aorta, coronary arteries, and the large arteries that supply blood to the brain.

How bad is Joe’s CHF? • There are different classification systems: • New York Heart Association • American College of Cardiology/ American Heart Association guidelines
New York Heart Association classification • Based on the ability to function • Level I – No symptoms, no activity limits • Level II – Mild symptoms, slight limits, comfortable at rest • Level III – Moderate limited activity, comfortable only at rest • Level IV – Severe restrictions, symptomatic at rest • (Porth, 2004)
ACC/AHA Heart Failure Guidelines • Based on risk factors, ventricular remodeling, and progressive symptoms • Stage A - High risk for HF, no structural heart disease, no symptoms • Stage B – Structural heart disease, no symptoms • Stage C – Structural heart disease with prior or current symptoms • Stage D – Refractory HF • (Hunt et al, 2005)
Joe becomes very short of breath and presents to the emergency room: • 56 YEAR OLD MALE • Hx: diabetes, CAD, HTN • C/O SOB, “light headed”
Admitted by Dr. Heart • Diagnosis: CHF • Physician orders: • Chest XRAY • Chemistry panel, BNP, CBC • EKG • Echocardiogram • 2 gram sodium diet • Activity as tolerated
For the next three days you monitor Joe: Daily weight Intake and output Blood sugars Vital signs Activity level
Dr. Heart discharges Joe and tells you to do patient education prior to discharge. What do you teach?
#1 reason for readmission to the hospital is non-compliance with treatment. • (Clark & Dunbar, 2003)
What do we teach? Medications and side effects
Which classification of medications promotes the excretion of fluid, reduces preload, and operates at an optimal part of the Frank-Starling curve? Diuretics Beta blockers Digitalis ACEinhibitors
Great Job!! Click here
Sorry, let’s think about that again. Click here
Which group of drugs increase the force and strength of ventricular contraction, decreases heart rate, and increases diastolic filling time? Diuretics Beta blockers Digitalis ACEinhibitors
