Changes in cardiac ultrasound characteristics and prognostic value in patients with acute coronary syndrome before and after coronary intervention therapy
Objective To explore the changes in cardiac ultrasound characteristics and prognostic value of coronary intervention in patients with acute coronary syndrome.Methods One hundred and fifty acute coronary syndrome(ACS)patients admitted to our hospital from November 2021 to May 2023 were selected as study participants.All patients underwent percutaneous coronary intervention(PCI)and a one-year outpatient follow-up was performed to analyze the treatment status and follow-up results.Changes in cardiac ultrasound parameters before and after treatment were compared.Subsequently,25 patients with adverse reactions during the perioperative period and cardiovascular events within a year were classified into a poor prognosis group,while the remaining 125 patients belonged to a good prognosis group.Clinical data and cardiac ultrasound parameters were compared and the prognosis used as a dependent variable and included in the Logistic regression model.The prognosis of ACS patients was an independent influencing factor.Results Of 150 patients with acute coronary syndrome,there were no deaths during the perioperative period.The incidence of perioperative adverse reactions was 4.7％(7/150),and the incidence of cardiovascular adverse reactions was 12.0％(18/150)for one year.After treatment,the patients'cardiac index(CI)and left ventricular ejection fraction(LVEF)were higher than those before treatment,while left ventricular end diastolic diameter(LVEDD)and left ventricular end systolic diameter(LVESD)were lower than those before treatment(P＜0.05).There was no significant difference in gender,body mass index(BMI),comorbidities,history of alcohol consumption,LVESD and LVEDD between the group with good prognosis and the group with poor prognosis(P＞0.05).However,there were significant differences in age,NYHA heart function classification,smoking history,thrombolysis thrombolysis test blood flow grading(TIMI),CI and LVEF between the group with good prognosis and the group with poor prognosis(P＜0.05).Age,NYHA heart function levels,TIMI,CI and LVEF are independent risk factors that influence the prognosis of interventional treatment of acute coronary syndrome(P＜0.05).Conclusion There can be significant changes in the relevant cardiac ultrasound parameters of patients with acute coronary syndrome before and after coronary inter-vention treatment.Dynamic monitoring of cardiac ultrasound parameters can evaluate the prognosis of acute coro-nary syndrome,and the convenience and non-invasive nature of cardiac ultrasound can be used for early predic-tion of patient prognosis,providing reference for the development of comprehensive clinical intervention measures.
