Two weeks after the experimental myocardial infarctions, the Seattle researchers injected 1 billion
heart muscle cells derived from human embryonic stem cells, called human embryonic stem cell - derived cardiomyocytes, into the
infarcted muscle.

The results showed patients who received metoprolol had much smaller
infarcts than those who received the control treatment, and that this smaller
infarct size was linked to greater
heart contractility.
In an editorial accompanying the published article in Circulation, experts from the Technische Universität and the Munich
Heart Alliance, Gjin Ndrepepa and Adnan Kastrati, affirmed that, if confirmed by a subsequent analysis of large numbers of patients, the results of METOCARD - CNIC trial are likely to lead to a change in clinical practice: «In this regard, a pharmaco - protective strategy able to reduce
infarct size by 20 percent when used in conjunction with primary PCI nurtures great hope in clinical benefit.»
The success of the treatment was determined by several measures:
infarct size (a smaller
infarct means less muscle death; wall thickening (a thicker
heart wall during contraction indicates the preservation of healthy functioning
heart muscle); and recanalization rates, which is a measure of restoration of blood flow to the
heart.
Over all, the combination of ultrasound / microbubbles and a low dose of tPA resulted in the most significant preservation of healthy
heart tissue and the smallest
infarct size.
One reason for this is that women suffer «different»
heart attacks: Statistically, they tend to be 10 years older at the time of the
infarct and are more likely to have accompanying conditions such as diabetes.

infarct zone of the
heart tissue, counterstained nuclei with DAPI (blue).
Cell therapy has been shown to be effective in reducing the
infarct (scarring) caused by a
heart attack as well as improving
heart function when certain cell types are used — particularly cells from a person's own fat (adipose tissue).
After a
heart attack (myocardial infarction), inflexible scar tissue known as an
infarct is left while some
heart muscle cells remain alive, though with inadequate blood flow.
In MESA, researchers found a reverse relationship, with African Americans having the lowest rates of
heart failure due to myocardial
infarct (at 25 percent), while other races had a much higher proportion: Caucasians (40 percent), Hispanics (42 percent), and Chinese Americans (100 percent.)
Researchers also observed elevation of lipid peroxide levels in
heart tissue, as well as an increase in
infarct size.
Silymarin (milk thistle) significantly reduced
infarct size at 500 mg per kg dose, as shown by the altered serum and
heart tissue.
Proper hydration is associated a reduction in hypertension, fatal coronary
heart disease, venous thrombo - embolism, and cerebral
infarct [24].
In a very large scale study in Denmark involving over 50,000 adults between the ages of 50 — 64 years, intake of oats has been associated with decreased risk of
heart attack (also known as myocardial
infarct, or MI).
Darvocet and Darvon — we are accepting Darvocet and Darvon cases where the patient sustained a
