Objectives To evaluate the clinical outcomes and identify its associated factors in patients with acute coronary syndromes (ACS) in Tianjin city. Methods Data were obtained from Tianjin urban employee basic medical insurance database. Adult patients who were discharged alive after the first ACS-related hospitalization (the index hospitalization) during January, 2012 to December, 2014 and without malignant tumor were included. Clinical outcomes were measured by subsequent major adverse cardiovascular events (MACE) including hospitalization for myocardial infarction (MI) or stroke, all-cause death, or their composite endpoint. Cox model was used to explore the factors associated with MACE. Results 22 041 patients were identified, in which 9.5% experienced MACE during follow-up with a mean number of 1.3 MACEs. 3.1% of patients had MI, 5.7% had stroke and 1.4% had all-cause death. Among patients who experienced MACEs, the average time from index discharge to the 1st MACE was 143.2 days. Patients being older, male or had higher Charlson Comorbidity Index (CCI) were more likely to experience MACE. Patients who had prior stroke and prior all-cause hospitalization were also more likely to experience MACE, whereas patients who had prior angina, prior β-blockers utilization and received percutaneous coronary intervention (PCI) during index event were less likely to experience MACE. Conclusion Stroke is the most common type of MACE among ACS patients in Tianjin, China. Almost half of the 1st MACE occur within the 3 months after ACS. Patients who are older, male, have higher CCI or have prior stroke are at higher risk of MACE.
Acute coronary syndromes (ACS) are clinical syndromes caused by the instability or rupture of coronary atheromatous plaques. The development and treatment of ACS are closely related to some ocular manifestations. Hypertensive retinopathy, retinal arteriovenous occlusion, diabetes retinopathy, and age-related macular degeneration are associated with a high risk of ACS. Retinal vascular occlusion may be a potential postoperative complication of the percutaneous coronary intervention for ACS. Ocular parameters such as the retinal vascular diameter and density, the blood flow velocity of the ophthalmic artery, and the choroidal thickness are expected to be markers for assessing or predicting the risk of ACS, which are of important value for the prevention of cardiovascular events such as ACS.
