CHF and HbA1C

According to a study published  in The American Journal of Cardiology, diabetic patients with heart failure who had lower levels of glycosylated hemoglobin were more likely to die or need urgent heart transplantation during two years of follow-up compared with those with higher HbA1c levels.  Yes, y0u read that right.    Who knows, maybe the study is flawed but one professor of cardiology said in the American Medical News that, “We may find that doctors who treat patients who have advanced heart failure and diabetes may not need to focus on aggressively lowering blood [glucose], but rather keep it under moderate control”.   So, once again, what about the quality indicators?   Sure the patient may die but at least their HbA1C is down.  Am I right?
