What is the next step for a 78-year-old patient with Diabetes Mellitus (DM) and Hypertension (HTN) who develops hemoptysis after receiving streptokinase (streptokinase) for an acute myocardial infarction (MI) with ST segment elevation in anterior leads on electrocardiogram (ECG)?

Management of Hemoptysis Following Streptokinase in STEMI

Transfusion of 2 units of Fresh Frozen Plasma (FFP) is the most appropriate next step for this 78-year-old patient with DM and HTN who developed hemoptysis after receiving streptokinase for anterior STEMI.

Understanding the Clinical Scenario

This case presents a serious complication of thrombolytic therapy. The patient has received streptokinase for an anterior STEMI and subsequently developed hemoptysis, indicating pulmonary hemorrhage - a rare but potentially life-threatening complication of fibrinolytic therapy.

Rationale for FFP Administration

Streptokinase activates the fibrinolytic system by converting plasminogen to plasmin, which degrades fibrin clots. When pulmonary hemorrhage occurs as a complication:

• FFP contains all coagulation factors and can rapidly reverse the fibrinolytic state 1
• FFP provides immediate replacement of depleted coagulation factors
• This intervention addresses the underlying mechanism of bleeding by restoring hemostatic function

Why Other Options Are Less Appropriate

1. Factor VIII (Option A):

   • Not indicated as first-line therapy for streptokinase-induced bleeding
   • More specific for hemophilia A, not for generalized fibrinolytic states
   • Would not address the broad coagulation factor depletion caused by streptokinase

2. Vitamin K (Option B):

   • Acts too slowly (takes hours to days to work)
   • Only affects vitamin K-dependent factors (II, VII, IX, X)
   • Not effective for acute reversal of fibrinolytic activity

3. Aminocaproic acid (Option C):

   • While it inhibits fibrinolysis, it's less immediate than FFP
   • Better suited for prevention rather than treatment of established hemorrhage
   • May increase thrombotic risk in a patient who already has coronary thrombosis

Management Algorithm for Hemoptysis After Thrombolysis

1. Immediate assessment:

   • Evaluate hemodynamic stability
   • Assess oxygen saturation and respiratory status
   • Quantify amount of hemoptysis

2. Initial interventions:

   • Administer 2 units of FFP to reverse fibrinolytic state 1
   • Provide supplemental oxygen
   • Position patient with bleeding lung in dependent position if unilateral

3. Monitoring and further management:

   • Continuous cardiac monitoring
   • Serial hemoglobin measurements
   • Chest radiographs to monitor resolution 2
   • Consider CT thorax or bronchoscopy only if hemoptysis persists or worsens

Important Clinical Considerations

• Pulmonary hemorrhage occurs in approximately 0.4% of patients receiving thrombolytic therapy 2
• Hemoptysis following thrombolysis typically resolves within 11 days with appropriate management 2
• The risk of stroke, particularly hemorrhagic stroke, is higher with tissue plasminogen activators than with streptokinase, but pulmonary hemorrhage can occur with either 3
• Patients with recent respiratory infections (as in one case report) may have increased risk of pulmonary hemorrhage 4

Prevention of Future Complications

After stabilizing the current hemorrhage:

• Consider PCI as the reperfusion strategy if further intervention is needed
• Carefully weigh risks/benefits before administering additional antithrombotic therapy
• Monitor for recurrent bleeding

Remember that while hemoptysis is concerning, most cases resolve with appropriate management and do not lead to significant hemodynamic compromise 2.
