Patient:
Reason for Visit:
Follow-up for PH-SCD
Evaluation of symptoms (e.g., dyspnea, fatigue, chest pain, right heart failure)
Assessment of response to treatment and hemodynamic status
History:
Present Illness:
Onset, duration, and severity of symptoms suggestive of PH-SCD:
Dyspnea (shortness of breath) – progressive, worse with exertion
Fatigue
Chest pain (angina-like)
Syncope (fainting) – in severe cases
Right heart failure symptoms (ankle swelling, jugular venous distention)
Functional limitations due to symptoms
World Health Organization (WHO) Functional Class (assessment of exercise tolerance)
Past Medical History (PMH):
Diagnosed with Sickle Cell Disease (SCD) and date of diagnosis
Prior hospitalizations for SCD complications (e.g., pain crises, acute chest syndrome)
Prior evaluation or diagnosis of PH
Social History:
Smoking history (can worsen PH)
Family history of SCD or PH (rare)
History of frequent blood transfusions (can contribute to iron overload)
Physical Exam:
Vital Signs: Assess for tachypnea (rapid breathing), jugular venous distention (JVD), and hypotension (low blood pressure).
General: Look for signs of cyanosis (bluish skin discoloration) and peripheral edema (swelling in legs).
Cardiovascular:
Palpate for a palpable pulmonic second heart sound (suggestive of right ventricular strain).
Assess for peripheral pulses (weak or absent pulses suggest severe PH).
Pulmonary:
Auscultate for breath sounds (presence of crackles).
Diagnostic Tests (may be ordered depending on clinical presentation):
Chest X-ray: May show signs of enlarged pulmonary arteries.
Electrocardiogram (ECG): May show signs of right heart strain.
Echocardiogram: Non-invasive assessment of right ventricular function and pulmonary artery pressures.
Right heart catheterization: The gold standard for diagnosing PH and measuring pulmonary artery pressures directly.
Blood tests:
Complete Blood Count (CBC) to assess for anemia
Serum ferritin levels to assess for iron overload
Other tests to rule out other causes of symptoms
Assessment:
Confirmation of PH-SCD: Based on diagnostic workup and presence of SCD.
Functional class: WHO Functional Class for exercise tolerance.
Hemodynamic status: Severity of pulmonary artery pressure elevation.
Severity of SCD: Consideration of factors like frequency of crises, transfusion history.
Response to treatment: Evaluate effectiveness of current medications and identify any side effects.
Plan:
Treatment plan based on severity of PH, SCD, and individual patient factors:
Pulmonary vasodilators: Similar to general PH treatment (e.g., calcium channel blockers, endothelin receptor antagonists)
Hydroxyurea: Disease-modifying medication for SCD that may also benefit PH-SCD.
Chronic red blood cell transfusions: To reduce sickling and improve oxygen delivery (may worsen iron overload, requiring chelation therapy).
Phlebotomy: Removal of red blood cells to manage iron overload (if indicated).
Diuretics: To manage fluid buildup (common complication of right heart failure).
Other medications: Oxygen therapy for hypoxemia, digitalis for heart rhythm control (if indicated).
Non-pharmacological measures: Weight management, smoking cessation, exercise rehabilitation (tailored to individual capabilities).
Referral to a hematologist and pulmonologist with expertise in PH-SCD: For complex cases or consideration of advanced therapies (e.g., balloon pulmonary angioplasty, lung transplantation).
Patient education: Provide information about PH-SCD, the importance of adherence to all treatment regimens (SCD and PH), healthy lifestyle modifications, signs and symptoms to watch for, and the importance of regular follow-up.
Follow-up:
Schedule for regular follow-up appointments with both hematologist and pulmonologist to monitor symptoms, assess response to treatment with clinical evaluation and imaging studies (e.g., echocardiogram), and adjust medications as needed.
