The efficacy of thrombolytic therapy for massive infarction depends on the type of infarction. If the patient has an acute non-ST-segment elevation infarction, thrombolytic therapy is generally not recommended, but if the patient has an ST-segment elevation infarction, thrombolytic therapy can generally be performed and the efficacy is good.
The mechanism of non-ST-segment elevation infarction is the formation of white blood clots by platelets and fibrin, and the blood vessels supplying the heart are not completely blocked, so the effect of thrombolytic therapy is not obvious. The mechanism of ST-segment elevation infarction is the formation of red blood clots, and the blood vessels supplying the heart are almost completely blocked, so thrombolytic therapy can reopen the blood vessels to achieve good results.
Heart attack is categorized into acute heart attack and old heart attack. Acute heart attack is very dangerous and should be evaluated in time to take targeted treatment. The effect of thrombolytic therapy varies from person to person, and the prognosis needs to be evaluated according to the patient’s condition.
