Guest guest Posted December 31, 2005 Report Share Posted December 31, 2005 > Please consider the study reported at < > http://www.ncbi.nlm.nih.gov/entrez/query.fcgi? cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=16368297&query_hl=1&it ool=pubmed_docsum OK, but that was " all-causes " mortality, not just mortality from heart attack within 12 months. That could presumably have included those who got themselves run over by a truck or who fell out of a tree. Most people who have been on this list for some time would not be surprised by that result. We were always agreed that it is better to get off oral medication by diet and exercise, or at least reduce the dose, if it is at all possible without sacrificing too much HbA1c (it is a trade-off) and we have always said that we all have to go sooner or later but we would prefer to go naturally rather than with a batch of complications. We cannot expect that to be without some kind of trade-off. Some time back I did mention a report of a 92- year-old man in Germany who had had diabetes for over 50 years and had doctor's written confirmation that he had had every diabetes complication known to medical science and was still going strong. He was objecting to the doctor's attempt to alter his self-determined insulin dose to improve his BG control! > On the other hand, please also consider the study reported at > http://www.ncbi.nlm.nih.gov/entrez/query.fcgi? cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15616228&query_hl=4&it ool=pubmed_docsum> > or <*http://tinyurl.com/c96dr* >. This second study concludes, with and > againt the results cited by , that " the severity of > diabetes or the preclinical duration of diabetes and the > need for drug therapy, and not the therapy itself, is an > explanation for heart failure in patients with type 2 > diabetes. " Yes, but that report says that it was concerned with heart failure in DM2 patients on oral medication in the first year after diagnosis and that the effect was not found after the first year. I deduce from that: On oral medication, if you survive the first 12 months after diagnosis, you are over the point at which your chances of survival from a serious cardiac event are adversely affected by the length of time before you were diagnosed or by the severity of your diabetes. The two reports still do not alter my opinion that the blood pressure tester and the periodic stress EKGs and the regular cardiac exercise to make sure that the results are good are just as important to a diabetic as the HbA1c measurements. Not more important but just as important. The moral is that diabetes is by far not the worst thing that can happen to you and while you are working on your diabetes you might just as well pay close attention to all other aspects of health care from which you could benefit and the heart must surely be the first candidate for attention.

Do you suggest that patients having A1C 7.0 or less are more likely to get run over by a truck or fall out of a tree ? Other things being equal, I'd expect these risks to be higher for the *more* hyperglycemic group. So, using this (admittedly less than perfectly precise) outcome variable would seem to me to lead to an understated, rather than overstated, result of the sort actually obtained. We were always agreed that it is better to > get off oral medication by diet and exercise, or at least reduce the > dose, if it is at all possible without sacrificing too much HbA1c.... > Please note that the two patient groups were similar in " insulin, metformin, and glitazone use. " So, we don't seem to be able to point to the method of glycemic control as a factor explaining the result. As odd as the result may be, there seems to be *something* going on. I wish the full-text article were available.... Most people who have been on this list for some time would not be > surprised by that result. > I must misunderstand your statement that the study results were unsurprising. You're saying that the notion that low A1C is more dangerous (among patients studied) than high A1C makes sense to you? Even the study's authors had trouble interpreting that result . In any case, please bear in mind my statement that the results of any single study don't mean all that much. In that context, I think that we agree on more than we disagree. But, when a study's results are as odd as these, they're hard to entirely ignore, even if they're all but impossible to reliably interpret.
