Unstable heart failure is defined as class IV cardiac failure with symptoms that do not respond to empiric treatment, which causes hypotension, renal failure, hyponatremia and/or symptomatic ventricular arrhythmias. It may be reversible or refractory. Refractory or "end-stage" heart failure is an indication for heart transplant, provided that: a) all reversible ethiologic factors have been corrected; and b) aggressive treatment in the intensive care unit under hemodynamic monitoring has not been able to stabilize heart failure.
不稳定型心力衰竭被定义为IV级心力衰竭，其症状对经验性治疗无反应，可导致低血压、肾衰竭、低钠血症和/或有症状的室性心律失常。它可能是可逆的或难治性的。难治性或“终末期”心力衰竭是心脏移植的指征，前提是：a）所有可逆的病因因素均已得到纠正；b）在血流动力学监测下于重症监护病房进行的积极治疗未能使心力衰竭稳定。
