Primary Diagnosis: _______________________________________________

  1. Describe the pathophysiology of the primary diagnosis in your own words. What are the patient’s risk factors for this diagnosis?
    Pathophysiology of Primary Diagnosis

Causes Risk Factors (genetic/ethnic/physical)

  1. What are the patient’s signs and symptoms for this diagnosis? How does the diagnosis impact other body systems and what are the possible complications?
    Signs and Symptoms – Common presentation How does the diagnosis impact each body system? Complications?
  2. What are other potential diagnosis that present in a similar way to this diagnosis (differentials)?

What diagnostic tests or labs would you order to rule out the differentials for this patient or confirm the primary diagnosis?

  1. What treatment options would you consider? Include possible referrals and medications.

2. Signs and Symptoms:

  • Common presentation: Chest pain (crushing, squeezing, radiating to arm/jaw/back), shortness of breath, sweating, nausea, fatigue, anxiety, fainting
  • Body System Impact:
    • Cardiovascular: Decreased heart function, abnormal heart rhythm, heart failure
    • Respiratory: Difficulty breathing, fluid buildup in lungs
    • Musculoskeletal: Weakness, fatigue
    • Neurological: Anxiety, confusion
  • Complications: Arrhythmias, heart failure, cardiogenic shock, death

3. Differential Diagnoses:

  • Pericarditis: Inflammation of the sac surrounding the heart, causing chest pain
  • Aortic dissection: Tear in the aorta causing chest pain and other symptoms
  • Esophageal spasm: Chest pain mimicking heart attack
  • Pneumonia: Chest pain, fever, cough
  • Anxiety attack: Chest pain, shortness of breath, anxiety

4. Diagnostic Tests:

  • Electrocardiogram (ECG): Shows electrical abnormalities in the heart
  • Blood tests: Troponin levels (marker of heart muscle damage), CRP (inflammation marker), electrolytes
  • Chest X-ray: May show lung fluid or enlarged heart
  • Echocardiogram: Ultrasound of the heart to assess damage and function
  • Coronary angiography: Visualizes blood flow through coronary arteries

5. Treatment Options:

  • Emergency care: Oxygen, pain management, medications to dissolve clots and improve blood flow
  • Reperfusion therapy: Angioplasty (stenting) or bypass surgery to restore blood flow
  • Medications: Aspirin, blood thinners, beta blockers, cholesterol-lowering drugs
  • Cardiac rehabilitation: Exercise program to improve heart function and prevent future events

Possible Referrals:

  • Cardiologist
  • Cardiovascular surgeon
  • Cardiac rehabilitation specialist

Additional Notes:

  • Early diagnosis and treatment are crucial to minimize heart damage and improve outcomes.
  • Lifestyle changes (healthy diet, exercise, stress management) are essential for preventing future heart attacks.
  • Patient education about symptoms, risk factors, and prevention strategies is important for long-term management.

Sample Answer

 

Mind Map: Myocardial Infarction

Primary Diagnosis: Myocardial Infarction (Heart Attack)

1. Pathophysiology:

  • Cause: Atherosclerosis (plaque buildup) in a coronary artery leads to sudden occlusion (blockage), cutting off blood flow and oxygen supply to a portion of the heart muscle (myocardium).
  • Risk Factors:
    • Genetic: Family history of cardiovascular disease, specific gene mutations
    • Ethnic: African Americans, Hispanics, South Asians have higher risk
