Laser Transmyocardial Ablation/Revascularize??

My father had two MIs in 2 mos. (small ones) which required
emergency care (intubation, etc.).  

He had Quad. bypass 5 years ago, when he already had 9 or
10 partial(varying from 20 to 95%) blockages.  He also
has thickenned valve (aortic)which was left alone.  
His left ventricle was thickened before that bypass
surgery.

His cardio. is suggesting medical treatment hoping to
slow down the process, and not intervention.  He has
not done angiography or thalium test, yet, but has done
plain echo.

I am wondering if one should consider the controversial
Laser Transmyocardial process?  Any feedback or
experience?

    Has anyone had any experience with Chitosorb/ chitocan? Please let me
    know, I’m very interested. Thanks!

    Nothing on your list has been demonstrated to be of any value at all,
    but of course most of your items have never been well studied.
    Beta-carotene has been very well studied, notably in the
    22000-patient, 15-year Physicians Health Study.  It was resondingly
    worthless.

      I thought that Americans had the most expendsive urine in the world,
    but now I see that we may have some northern competition.

    You mean to imply that folic acid and vitamin C supplements are nothing
    but urine enrichments? The tone of this statement is reminiscent of those
    given for so many years by the cigarette industry that smoking has not
    been shown to cause cancer. In both cases there seems to be enough
    circumstantial evidence to treat the claims as probably correct.  Proof
    in the rigorous mathematical sense is improbable, of course.

      I’m a little sorry that I got into this, since the vitamin pushers
    are so full of passionate intensity.  In the future, I shall regard
    vitamin-related messages directed to this newsgroup as spams.
    Send them to alt.something.

      But for the moment, let’s say a little about what is evidence and
    what is not.  Smoking causes cancer in multiple animal models, and one
    can see dose-related effects in well-matched human epidemiologic
    studies.  Some phenomena that are biologically related to
    carcinogenesis are easily demonstrable with tobacco-smoke components
    in vitro.  It is not ethical or feasible to conduct intervention
    studies,  but epidemiologic/animal/in-vitro studies don’t get any
    better or any more uniform.

      On the other hand, it is perfectly possible to do randomized,
    blinded, controlled intervention studies of vitamin supplements.
    Several such studies have been done in the cardiovascular area
    with respect to beta-carotene, with a total of close to half a million
    patient-years of data (all in middle-aged men, so the results may not
    apply to women).   Beta-carotene is consistently no good.

      The only other intervention trials that I know about are those of
    vitamin E.  Vitamin E doesn’t look too bad, actually; I must amend my
    earlier, dismissive statement with respect to Goldberg’s whole list.
    Vitamin E was beneficial in one secondary-prevention trial (Lancet
    347:781-786, 1996; about 3000 patient-years) and in one
    primary-prevention trial (JAMA 275:693-698, 1996; about 100000 patient
    years; all patients were smokers), although there were no differences
    in all-cause mortality in either trial.

      There are no intervention data connecting folate or vitamin C to
    cardiac outcomes.  Epidemiologic evidence for folate is good, but it’s
    no better than the **epidemiologic** evidence for beta-carotene, which
    FLUNKS as an intervention.  The folate scene is very complex; on the
    one hand,  supradietary intake by pregnant women reduces the incidence
    of neural-tube defects in their babies, and serum levels of folate are
    inversely correlated with serum levels of homocysteine, which are in
    turn directly correlated with various bad outcomes (especially in
    blacks, for some reason).  On the other hand, some of the most
    successful cancer therapy (methotrexate for Hodgkin’s disease or for
    choriocarcinoma) is anti-folate therapy; I wouldn’t be terribly
    surprised to find that large folate supplements are associated with
    small increases in the risk of cancer.  As if that were not complex
    enough, everything is connected with everything else; for example,
    people who quit smoking seem to seek out a disproportionate increase
    in their dietary folate (Br J Nutr 74:27-38, 1995).

            The randomized, controlled intervention studies are not as
    supportive of the beneficial effects as are animal model studies.  In
    the latter case, there are plenty of studies demonstrating the
    protective effects of anti-oxidants including
    alpha-tocopherol,against ischemic-reperfusion injury and vascular
    injuries.  However, it always seems thus – whatever the intervention.

            Personally, I believe that there is plenty of room for doubt
    and advocacy on all sides on this particular issue.  Certainly,
    sufficient, to warrant the ‘advocacy’ of vitamin supporters, who were
    demonized as ‘spammers’ in the previous post.
