Analysis for the Onset Features and Prognosis in"Migratory Birds"Population With Acute Myocardial Infarction in Hainan Province / 中国循环杂志

ABSTRACT

Objective: To explore the onset features and prognosis in "migratory birds" population with acute myocardial infarction (AMI) in Hainan province. Methods: A total of 1246 patients diagnosed as coronary aretery disease and admitted in our Hospital during 2012-2015 were consecutively enrolled, including "Migratory birds" group (n=197) and Hainan group (n=58). Clinical information, risk factors, interventional strategies and in-hospital outcomes were recorded and compared. Results: The patients' age, histories of hypertension, diabetes, smoking and blood lipids were similar between 2 groups. In "Migratory birds" group, the average time from arriving Hainan to AMI onset was (3.15±2.67) days. Compared with Hainan group, "Migratory birds" group had the higher ratio of acute STEMI occurrence [70.56% (139/197) vs 51.72% (30/58), P=0.003], more patients with single+double coronary artery diseases (P=0.009), and thrombus aspiration (P=0.008); while less stent implantation, P=0.007. "Migratory birds" group also presented the higher ratios of cardiac shock after AMI (12.69%vs 3.45%, P=0.044), and cardiac shock+death (16.24% vs 3.45%, P=0.022). Conclusion: "Migratory birds" AMI patients had the higher ratios of acute STEMI, with more simple lesions and thrombus aspiration, they usually had poor prognosis.
