释义

Reperfusion arrhythmia

英语百科

Reperfusion therapy

Thrombus material (in a cup, upper left corner) removed from a coronary artery during a percutaneous coronary intervention to abort a myocardial infarction.  Five pieces of thrombus are shown (arrow heads).
Coronary artery bypass surgery during mobilization (freeing) of the right coronary artery from its surrounding tissue, adipose tissue (yellow).  The tube visible at the bottom is the aortic cannula (returns blood from the HLM).  The tube above it (obscured by the surgeon on the right) is the venous cannula (receives blood from the body).  The patient's heart is stopped and the aorta is cross-clamped.  The patient's head (not seen) is at the bottom.

Reperfusion therapy is medical treatment that restores blood flow through blocked arteries, typically after a heart attack (myocardial infarction). Categories of reperfusion therapy thus include clot-busting (fibrinolytic) drugs and procedures to open arteries with stents, or to graft arteries around blockages. These interventions have become so central to the modern treatment of acute myocardial infarction, that we are said to be in the reperfusion era. Patients who present with suspected acute myocardial infarction and ST segment elevation (STEMI) or new bundle branch block on the 12 lead ECG are presumed to have an occlusive thrombosis in an epicardial coronary artery. They are therefore candidates for immediate reperfusion, either with thrombolytic therapy, percutaneous coronary intervention (PCI) or when these therapies are unsuccessful, bypass surgery.
