Abstract
Objective The aim of this study was at investigating the risk stratification and prognostic value of hypersensitive troponin T (hs-TnT) combined with matrix metalloproteinase 2 (MMP-2) in patients with acute coronary syndrome (ACS). Methods 80 patients with coronary syndrome admitted to our hospital from January 2019 to January 2020 and 40 healthy people (control group) in the same period were selected. According to different types of diseases, the patients were divided into an acute group (n = 40) and stable group (n = 40). Besides, they all were monitored by the hs-TnT value, serum MMP-2, and coronary angiography at admission and the comparative analysis was carried out. The patients in both groups were followed up for 30 days, and the incidence of adverse cardiovascular events in the patients during this period was recorded. Results Compared with those in the control group, the MMP-2 and hs-TnT levels in the acute group and the stable group were significantly higher and the MMP-2 and hs-TnT levels in the acute group were significantly higher than those in the stable group, with statistically significant differences (P < 0.05). The 30-day follow-up results showed that the incidence of adverse cardiovascular events in the acute group was significantly higher than that in the stable group, with statistically significant differences (P < 0.05). The hs-TnT and MMP-2 levels in the acute myocardial infarction (AMI) group were significantly higher than those in the unstable angina pectoris (UAP) group, with statistically significant differences (P < 0.01). The hs-TnT and MMP-2 levels in the non-single-vessel group were significantly higher than those in the single-vessel group, with statistically significant differences (P < 0.01). Conclusion The hs-TnT and MMP-2 high expression levels are closely associated with myocardial injury, and they can effectively predict the severity of patients' disease. In addition, the hs-TnT and MMP-2 elevated levels can be considered as an important index to judge the short-term treatment efficacy and the risk stratification of early ACS, playing an important role in clinical treatment and rehabilitation in the later stage.

Acute coronary syndromes (ACS) represent a major cause of mortality in our country
In order to further investigate the risk stratification and prognostic values of hypersensitive troponin T combined with matrix metalloproteinase 2 (MMP-2) in patients with acute coronary syndrome (ACS), 80 patients with coronary syndromes admitted to our hospital from January 2019 to January 2020 and 40 healthy people in the same period were selected as study objects and the summary report is as follows
The study results showed that the number of patients with smoking and drinking history in the acute group and the stable group was significantly higher than that in the control group (P < 0:05)
Summary
Acute coronary syndromes (ACS) represent a major cause of mortality in our country. Most patients with acute coronary syndrome (ACS) present with chest pain and a few with upper abdominal pain [1]. Segment elevation ACS and ST-segment elevation ACS [2,3,4]. This disease is caused by increased blood viscosity and myocardial oxygen consumption, as well as sympathetic excitation, resulting in the rupture or erosion of unstable atherosclerotic plaque, massive platelet aggregation, and even thrombosis. Non-ST-segment elevation ACS mostly occurs at night or at rest and lasts for more than 20 minutes. A diagnosis of ACS should be considered in all patients presenting with ischemic symptoms. Clinical signs and symptoms of ischemia include various combinations of chest
