###Human: Is CRTD good for heart patient with acute heart failure and MI? ###Assistant: Hi. As he had a heart attack, first priority is revascularization of angioplasty or bypass surgery. If this is done and heart function improves, then it will be good. In right bundle branch block, there is very little benefit of CRT (cardiac resynchronization therapy). If revascularization is not possible, then maximum medical therapy is best. Yes, ICD (implantable cadioverter defibrillator) is indicated. It should be considered once the patient is out of the acute episode and is stabilized. If the patient needs recurrent hospitalization for heart failure or recurrent BP drops that need medicines to raise it, then the option is left ventricular assist device (LVAD) or total artificial heart (TAH) or heart transplantation (subject to availability of facilities). First thing is to assess for revascularization if there is viable heart muscle. I hope this helps.
