ABSTRACT

Objectives: To analyze the variations of demography, risk factors and triggering factors in acute myocardial infarction (AMI) patients in Beijing area over recent 40 years from 1970s to 2010s. Methods: Our research included in 2 groups 1970s group, 1314 patients from Beijing collaborative group of coronary artery disease prevention and treatment from 1972-01 to 1973-12; 2010s group, 2200 patients from China AMI registry in Beijing area from 2013-01-01 to 2014-09-30. Demographic characteristics including gender, age, farmer proportion, risk factors and triggering factors for AMI occurrence were compared between 2 groups. Results: Compared with 1970s group, 2010s group had more patients>70 years of age (15.8% vs 25.6%, P<0.001), more with male gender (68.3% vs 75.6%, P<0.001) and the higher farmer proportion (6.5% vs 14.5%, P<0.001); 2010s group showed more patients with previous histories of stroke (6.2% vs 10.5%), MI (9.5% vs 11.9%) and diabetes mellitus (DM) (6.2% vs 27.6%), all P<0.05; 2010s group presented that less patients were triggered by mental stress (51.1% vs 15.2%, P<0.001), while more were induced by physical stress (40.0% vs 61.1%, P=0.007). Conclusions: There were significant changes in recent 40 years for AMI patients in terms of age, gender, farmer proportion, previous histories of stroke, MI and DM; it appeared as aging, androphany and ruralized trends. Physical stress and unhealthy lifestyle were the major triggering factors for AMI occurrence nowadays, more specific efforts should be conducted for heart disease prevention and education.
