BACKGROUND: The incidence of atherosclerotic cardiovascular disease (ASCVD) is increasing, with individuals experiencing acute myocardial infarction (AMI) at a younger age. Premature AMI is a serious condition with high rates of morbidity and mortality. This study aimed to identify clinical characteristics and risk factors associated with premature AMI and to evaluate the diagnostic value of those risk factors.
METHODS: The study collected data from first-time AMI patients who underwent coronary angiography at the hospital between January 2022 and April 2023. They were divided into two groups by age: premature AMI (men <55 years, women <65 years) and non-premature AMI. A control group of similar-aged patients without coronary artery disease was also included.
RESULTS: Out of 388 patients with first-time AMI, 313 were male, and 249 had ST-segment elevation myocardial infarction (STEMI). Among 73 control patients, 31 were male. Those with premature AMI had more risk factors like smoking, overweight, obesity, family history of coronary artery disease, and STEMI. They also had shorter hospital stays and higher diastolic blood pressure and faster heart rates. Single-vessel lesions were more frequent in premature AMI patients. After adjusting for confounding factors, smoking status (Odds ratio (OR) 4.454, 95% confidence interval (CI): 1.836-10.806, p = 0.001), glycated hemoglobin (HbA1c) level (OR 2.261, 95% CI: 1.219-4.193, p = 0.010), the non-high-density lipoprotein cholesterol (non-HDL-C)/HDL-C ratio (OR 4.394, 95% CI: 1.204-16.031, p = 0.025), and the monocyte-to-high-density lipoprotein ratio (MHR) (OR 6.164, 95% CI: 1.386-27.417, p = 0.017) were identified as independent risk factors for premature AMI development. The combination of these risk factors provided the greatest predictive value for premature AMI (area under the curve (AUC) = 0.874, 95% CI: 0.826-0.922, p < 0.001, sensitivity = 0.843, specificity = 0.795).
CONCLUSIONS: Premature AMI is often characterized by STEMI, single-vessel lesions, and a low occurrence of left main coronary artery involvement. Smoking status, HbA1c levels, the non-HDL-C/HDL-C ratio, and the MHR are significantly associated with premature AMI.
