Reperfusion injury is manifested as stunned myocardium, reversible microvascular injury, and, rarely, lethal myocyte necrosis.

Lethal myocardial reperfusion injury attenuates the full benefits of myocardial reperfusion in terms of MI size reduction and thus represents an important target for cardioprotection in PPCI patients (see Figure 2). However, no effective therapy cur-rently exists for reducing lethal myocardial reperfusion injury in

Recent advances in thrombolytic therapy and balloon angioplasty have resulted in reperfusion therapy as a logical maneuver in the treatment of 2020-10-06 2021-03-23 Reperfusion of the ischemic myocardium results in irreversible tissue injury and cell necrosis, leading to decreased cardiac performance. While early reperfusion of the heart is essential in preventing further tissue damage due to ischemia, reintroduction of blood flow can expedite the death of vulnerable, but still viable, myocardial tissue, by initiating a series of events involving both 2020-05-04 The donors also showed significant cytoprotective effects in cellular models of oxidative damage. Most importantly, the donors were found to exhibit potent cardioprotective effects in an in vivo murine model of myocardial ischemia-reperfusion (MI/R) injury through a H 2 S-related mechanism. 2011-08-18 2021-03-16 2020-10-14 Effects of I/R injury on left ventricular systolic and diastolic function as well as cardiac hypertrophy during aging. Overall design of the 8‐week study in young and old mice subjected to ischemia/reperfusion (I/R) injury or Sham operation (a). Left ventricular function was evaluated with echocardiography (Echo).

Myocardial reperfusion injury

Thrombolysis, percutaneous transluminal coronary angioplasty, and coronary bypass surgery are the general treatment strategies of cardiovascular events. All of these treatment strategies can cause a myocardial ischemia reperfusion (MI/R) injury, which is known to occur on the restoration of coronary blood flow after a With the limelight on ischemia driven therapy reperfusion injury is always ignored ; Ishemic limelight myocardial reperfusion is essential to salvage viable myocardium, it comes at a price ; This seminal observation, termed ischaemic preconditioning (IPC), has been replicated in all species tested, including humans, and can be readily applied to other organs and tissues. Lethal reperfusion injury is a paradoxical type of myocardial injury caused by the restoration of coronary blood flow after an ischemic episode. This review focuses on the mechanisms of the injury, Myocardial Reperfusion Injury.

Once coronary flow is restored, however, the myocardium is susceptible to another form of insult stemming from reperfusion of the previously ischemic tissue .

However, no effective therapy currently exists for reducing lethal myocardial reperfusion injury in patients who have undergone PPCI.
