Abstract
AIM: To estimate the time course of changes in basic electrocardiographic (ECG) parameters in patients with acute coronary syndrome (ACS) as possible predictors of in-hospital outcomes. Materials and methods. The data of 277 patients with acute coronary syndrome (ACS) were used; QT-interval duration was studied by means of an EC12C-01 cardioanalyzer; ST-segment deviation (ΣST), elevation (ΣST-E), and depression (ΣST-D) sums, and corrected QT-interval dispersion (DQTc) were calculated/RESULTS: There were highly significant differences of ΣST in all the patients groups at admission and differences of DQTc in ACS patients with and without ST-segment elevation. The survival rates were significantly different depending on the value of ECG parameters, such as ΣST, ΣST-D, and DQTc/CONCLUSION: The cardioanalyzer can automatically improve the estimation of in-hospital ECG changes and to determine predictors of an ACS outcome.

Электрокардиографические предикторы госпитальных исходов острого коронарного синдрома. - Резюме. Цель исследования. Оценка динамики основных параметров электрокардиограммы (ЭКГ) у пациентов с острым коронарным синдромом (ОКС) как возможных предикторов исхода в стационаре. Материалы и методы. Использованы данные 277 пациентов с ОКС. С помощью кардиоанализатора ЭК12К-01 исследована длительность интервала QT, рассчитаны сумма отклонения сегмента ST (ΣST), сумма подъема (ΣST+) и сумма снижения (ΣST-) сегмента ST, корригированная дисперсия интервала QT (DQTc). Результаты. Получены высокодостоверные различия ΣST во всех группах пациентов при госпитализации и различия DQTc у пациентов с ОКС с подъемом сегмента ST и ОКС без подъема сегмента ST. Выживаемость пациентов достоверно различалась в зависимости от таких параметров ЭКГ, как ΣST, ΣST-, DQTc. Заключение. Кардиоанализатор позволяет в автоматическом режиме улучшить оценку динамики ЭКГ в стационаре и определить предикторы исхода ОКС.×
