What BP target is recommended during the first 24 hours after tPA administration?

• A. Maintain BP below 180/105 mmHg (no aggressive lowering unless indicated)
• B. Lower BP to 120/80 immediately
• C. No BP management is required
• D. Keep BP above 200/110

Answer: (A)

After thrombolysis with tPA, controlling blood pressure in the first 24 hours is crucial to reduce the risk of hemorrhagic transformation while preserving perfusion to the still-ischemic brain. The best target is to keep blood pressure under 180/105 mmHg. This level lowers the chance of bleeding complications without excessively reducing cerebral perfusion to the penumbra. Lowering too aggressively to normal levels (like 120/80) can worsen neurologic outcome by diminishing collateral flow, and letting blood pressure stay very high (above 200/110) increases hemorrhage risk after tPA. If BP rises above the 180/105 target, use appropriate IV antihypertensives to bring it down toward the goal and maintain it there for the period after treatment.
