Key result
In a rat model, chronic myocardial ischemia induced by coronary artery constriction resulted in more severe postresuscitation myocardial dysfunction compared with sham or control groups.
Why the study?
Does chronic myocardial ischemia (coronary artery constriction) worsen postresuscitation myocardial function in a rat model of cardiac arrest and CPR?
Does chronic myocardial ischemia (coronary artery constriction) worsen postresuscitation myocardial function in a rat model of cardiac arrest and CPR?
A rat model of chronic myocardial ischemia exhibits severe postresuscitation myocardial dysfunction, providing a clinically relevant model for studying cardiac arrest and CPR in the context of chronic coronary disease.

Suggests chronic ischemia may worsen postresuscitation dysfunction; hypothesis-generating rat model requiring clinical validation.
Fang et al. (2006) studied Cardiac arrest and chronic myocardial ischemia. Left coronary artery constriction vs. Sham-operated group and control group was evaluated on Postresuscitation myocardial function. In a rat model, chronic myocardial ischemia induced by coronary artery constriction resulted in more severe postresuscitation myocardial dysfunction compared with sham or control groups.
