Cardiomyopathy Unmasked

Learning about Cardiomyopathy

Cardiomyopathy, a perplexing group of cardiac conditions, unveils itself as a complex interplay of structural and functional abnormalities within the heart muscle. Unlike many other cardiovascular diseases that target the blood vessels, cardiomyopathy directly impacts the heart’s ability to pump effectively, posing substantial risks to patient’s health and well-being. 

During a clinical rotation, I cared for a patient that was battling dilated cardiomyopathy. Witnessing her struggle with breathlessness and fatigue while trying to manage her medications and some of her lifestyle choices was very eye-opening. Through empathetic support and education, I saw her grow as she embraced a heart-healthy diet in the hospital and hope that her health would improve from all she learned in the hospital.

Cardiomyopathy Overview

Nursing Assessment for Cardiomyopathy

• 1. S/S Heart Failure
  • a. Fatigue
  • b. SOB
  • c. Dysrhythmias
  • d. Extra heart sounds (S3/S4)
  • e. Poor perfusion
  • f. Volume overload (JVD and pulmonary edema)
• 2. Echocardiogram or Chest X-ray
  • a. Heart is visibly enlarged or thickened

Therapeutic Management for Cardiomyopathy

1. No cure, only supportive
2. Encourage frequent rest
3. Minimize Stress
4. Manage HTN
       a. DASH diet
       b. ACE-Inhibitors (Angiotensin-converting enzyme)
       c. ARB’s (Angiotensin receptor blockers)
       d. Beta-Blockers
              i. ↓ force of contraction
             ii. ↓ workload
            iii. ↓ O2 demands
5. Ventricular Assist Devices
      a. Help eject blood from LV to the aorta

Nursing Case Study for Cardiomyopathy

Patient Profile:

Name: Danny Hernandez 
Age: 50 years old 
Gender: Male 
Medical History: Hypertension, obesity, type 2 diabetes 

• Fatigue and weakness 
• Shortness of breath on exertion
• Orthopnea (difficulty breathing while lying down)
• Swollen ankles and feet

• Echocardiogram: Showed left ventricular dilation and reduced ejection fraction (<30%), confirming dilated cardiomyopathy 
• Electrocardiogram (ECG): Displayed signs of left ventricular hypertrophy and atrial fibrillation
• Blood Tests: Elevated B-type natriuretic peptide (BNP) levels and evidence of renal dysfunction.

1. ACE Inhibitors: Initiated to reduce afterload and improve cardiac function 
2. Beta-Blockers: Prescribed to manage heart rate and improve ventricular function 
3. Diuretics: Administered to relieve fluid overload and reduce swelling 
4. Anticoagulants: Started due to presence of atrial fibrillation to prevent clot formation

1. Diet: Encouraged to adopt a heart-healthy diet low in sodium, saturated fats, and processed foods.
2. Exercise: Advised to engage in regular physical activity as tolerated to improve cardiovascular fitness.
3. Smoking Cessation: Counseled to quit smoking to reduce further cardiac strain 

3. Fluid Restriction:
 Mr. Hernandez’s fluid intake was closely monitored, and a fluid restriction plan was implemented to manage fluid retention.  

4. Cardiac Rehabilitation: 
Referred to a cardiac rehabilitation program to gradually increase exercise tolerance and improve overall cardiac health. 

5. Patient Education: 
Provided comprehensive education about dilated cardiomyopathy medication adherence, dietary restrictions, symptom recognition, and the importance of regular follow-up appointments.  

Outcome:

Over the course of his hospital stay, Mr. Hernanez’s symptoms improved with the pres ribed treatment plan. His shortness of breath decreased, and the swelling in his ankles and feet reduced. His heart rate and rhythm stabilized, and he was able to tolerate moderate physical activities without significant discomfort. 

During follow-up visits, Mr. Hernandez demonstrated compliance with his medication regimen and lifestyle modifications. His echocardiogram showed a slight improvement in ejection fraction, indicating a positive response to treatment. 

Conclusion 

This cardiomyopathy review provides essential knowledge for approaching the NCLEX with confidence. Understanding its prevention, management, and interventions empowers nurses to provide adequate care and save lives.
