Risk factors relating to the early complications of acute myocardial infarction after cardios-intervention treatment

Abstract

Purpose of the study. Identify the main risk factors for early complications of acute myocardial infarction after cardiac intervention and assess the prognostic risk. Materials and methods. To collect the statistical material to determine risk factors, the method of copying medical history data was used, and then the odds ratio was calculated. In doing so, we calculated odds ratios (OR) and 95% confidence interval (CI). Subsequently, the risk of early complications of acute myocardial infarction (AMI) in cardiointerventional intervention by Cox regression was predicted, which took into account the time of patient transportation by EMD team. The object of observation was to identify a patient with AMI who was delivered to a tertiary level of care. Results. In determining the consequences of cardiovascular intervention, such complications as aneurysm, arrhythmia, decreased ejection fraction, cardiogenic shock, and pulmonary oedema were considered. Most patients experienced improvement in health status – 60,7%, single complication was 18,9%, combined complications – 15,2%, patient death – 4,1%. Conclusions. By Cox regression analysis, it was proved that the cumulative risk of early GIM complications with cardiovascular intervention increased with 10 minutes of arrival of EMS with established ECG diagnosis (STEMI), which increased the risk of complications 1,9 times p (0,00) p (0,00) p (0,00); the presence of diabetes – 4,259 times, exp (β) 4,259 (p = 0,001); smoking – 2,988 times, exp (β) 2,988 (p = 0,001); increased BMI in the patient – 2 times, exp (β) 2,066 (p = 0,002).
