Abstract:
Objective To evaluate the predictive value of coronary CT angiography (CCTA) combined with four-dimensional speckle tracking echocardiography (4D-STE) for major adverse cardiac events (MACE) in patients with coronary atherosclerosis.
Methods A total of 103 patients with coronary atherosclerosis admitted to the North Area of Jiaozhou People's Hospital were examined by CCTA and 4D-STE. The incidence of MACE was counted at 1 year follow-up, and the degree of coronary stenosis and the amplitude of myocardial strains (GCS, GRS, GLS, GAS) in patients with and without MACE were analyzed.
Results The incidence of MACE was 20.39% (21/103) in the first year of follow-up. The degree of coronary artery stenosis in the MACE group was mainly grade 3 and 4, while that in the non-MACE group was mainly grade 1 and 2. The proportions of grade 3 (52.38%) and grade 4 (38.10%) in the MACE group were higher than those in the non-MACE group (17.07% and 2.44%). The proportion of grade 1 (0.00%) and grade 2 (9.52%) in the MACE group was lower than that in MACE group (30.49% and 50.00%) (P<0.05). There was no significant difference in the amplitude of myocardial strains (GCS, GRS, GLS, GAS) between the two groups (P<0.05).
Conclusion CCTA can accurately assess the degree of coronary artery stenosis, and 4D-STE can quantitatively assess the strain amplitude of myocardial segments. CCTA combined with 4D-STE can improve the predictive value of MACE and provide evidences for clinical prevention and treatment.
