Objective: This paper reports the medical records of a patient with coronary non-obstructive myocardial infarction (MINOCA) complicated with diabetes mellitus and malignant arrhythmia, emphasizing on the importance of primary prevention and early treatment for the prognosis of MINOCA patients. Methods: The case data of 1 patient diagnosed with MINOCA complicated with diabetes in our hospital were retrospectively analyzed. With “coronary non-obstructive myocardial infarction (MINOCA)” as the keyword, relevant literatures from January 2016 to December 2021 were retrieved and reviewed. Results: Through CNKI database, Wanfang Database, VIP database and Pubmed database, 626 related literatures were retrieved, 30 of which met the inclusion criteria. 33 domestic and foreign cases with complete case data were screened, 1 case was reported in this paper, and a total of 34 cases were summarized. There were 14 males (41.2%) and 20 females (58.8%), with a male to female ratio of 1:1.4. Age: (54.4 ±23) years, age range: 23~74 years;the main causes were coronary artery spasm, coronary artery plaque rupture and coronary artery thrombosis. The main clinical symptoms were chest pain, chest tightness and nausea. The main complications were hypertension. 20 cases (58.8%) had smoking history and 2 cases (5.8%) had drinking history. Troponin T was (1.16 ±1.15) ng/mL in 10 cases (29.4%) and Troponin I was (5.51 ±7.23) ng/mL in 24 cases (70.6%). Echocardiography showed abnormal ventricular segmental movement in 10 cases (29.4%), and the data of 16 cases (47.1%) included left ventricular ejection fraction (LVEF ≥ 50% in 12 cases (75%) and LVEF <50% in 4 cases (25%)). ST segment elevation in 20 cases (58.8%) and bundle branch block in 1 case (2.9%). 5 cases (14.7%) had dyslipidemia. The main treatment is anti-platelet, lipid-regulating and spasmolysis. Three patients (8.8%) died. Conclusion: Active control of cardiovascular risk factors and early treatment can effectively improve the prognosis of MINOCA patients.
