[Retrospective assessment of the preinfarction period]

The prodromal symptoms were retrospectively assessed in 100 patients with acute infarction of myocardium. The authors found preinfarction state in 48 per cent of the patients. In 95 per cent of the cases pain paroxysm was the basic manifestation. In 60,42 per cent it was accompanied by rhythm disturbances and to a lesser degree by some other symptoms: sense of lack of air, unusual fatigability, conductivity disturbances, vegetative manifestations, etc. In 43,75 per cent of the patients, electrocardiograms were recorded and in 80,95 per cent a lowered, bi-phase or negative T-wave was found and in 47,62 per cent--S--T depression.
