A total of 485 patients with complicated myocardial infarction (MI) in
the presence of concurrent abnormality and 104 patients with unstable
angina (UA) were followed up. Intravenous infusion of neoton (phospho
creatine) in a dose of 70 g at day 1 and 36 g at days 2 and 3 of the o
nset was made in 96 patients with MI, 28 patients with UA took neoton
in a daily dose of 30 g during 3 days. Control patients had convention
al therapy. In UA, poor outcomes (death, MI, no effects, referral of p
atients for bypass surgery) were seen in 4 (14%) patients on the drug
and in 18 (28 %) in the controls (p > 0.05). I MI, more rapid disappea
rance of events (heart failure and tachyarrhythmias) was observed in t
he major group, the mortality being 13.9%, the incidence of cardiac ru
ptures 6.4 versus 33.6 and 12.6% respectively, in the control. It is c
oncluded that large-dose neoton exerts positive action on the cause an
d outcome of UA and complicated MI.
