Objective To investigate the onset time distribution and influential factors in patients with acute myocardial infarction(ACI)with different body mass index(BMI)levels.Methods A cross-sectional study was conducted to collect clinical data from 1 000 patients with AMI who received treatment at Heilongjiang Provincial Hospital from January 2016 to November 2022.The patients were divided into groups based on different BMI levels:＜18.5 kg/m2 group(n=49),18.5-24 kg/m2 group(n=369),＞24-28 kg/m2 group(n=338),and＞28 kg/m2 group(n=244).The incidence of AMI was analyzed among patients with different BMI levels as per diurnal variation,seasonality,and weekday.Results A total of 1 000 patients were included in this study,including 648 men and 352 women.The mean age of these patients was 65 years(range 56-74 years).The median body mass was 70 kg(range 60-76 kg),the median height was 1.69 m(range 1.60-1.72 m),and the median BMI was 24.49 kg/m2(range 22.22-26.79 kg/m2).The onset time of AMI differed significantly among patients with different BMI levels in terms of the period from 0:00 to 5:59,winter,and Wednesday(P=0.047,0.029,0.005).Among all samples,the number of patients with a BMI of 18.5-24 kg/m2 was the highest,reaching 369 cases.Conclusion The incidence of AMI in patients with different BMI levels exhibits a regular distribution as per diurnal variation,seasonality,and weekday.
