TIME INTERVALS AT DIFFERENT STAGES OF MEDICAL CARE IN ACUTE CORONARY SYNDROME WITH ST SEGMENT ELEVATION ON THE ECG

Objective: to analyze the time intervals of medical care for patients with acute coronary syndrome with STsegment elevation on an electrocardiogram at different stages of care. Materials and methods. The study included 189 patients of both genders hospitalized with a diagnosis of acute coronary syndrome with ST-segment elevation, 3 age groups were formed, according to WHO criteria: 1 group (up to 59 years old) – 72 patients, 2 group (60–75 years old) – 69 patients and 3 group (over 76 years old) – 48 patients. The analysis of the time intervals of care at different stages was carried out, the intervals were compared in the group of men and women, as well as in different age groups. Results. The time interval from PMC to hospitalization in cPCI was 33 minutes, the interval from PMC to the start of PCI was 90 minutes, which corresponds to the standards of care. The median time to seek care from the onset of symptoms in our study was 191,65 ± 142,49 min. No gender differences were identified in seeking care. Younger patients (group under 60 years) sought care reliably earlier from the onset of symptoms than older patients, which is probably due to a more erased clinical picture in older patients. Conclusion. The main delay occurs at the symptom-PMC stage, which is the main problem. This indicator depends on the awareness of the population about the symptoms and danger of ACS. To improve this indicator, it is necessary to carry out educational work. The result of this activity should be an earlier recognition of ACS symptoms by patients and a reduction in the time from the onset of symptoms to the call of the NSR.
