Objective: To investigate the effects of tonifying Qi and activating blood circulation (SQABC), a method in Traditional Chinese Medicine (TCM), on end-point events in patients with myocardial infarction (MI) in this retrospective cohort study.
Methods: Clinical data were obtained from the medical records of patients with acute MI (AMI), both during hospitalization and follow-up, and included general demographic information (age, gender, and contact information), TCM regimens used, and end-point events.
Results: A total of 1596 patients with AMI were enrolled to this study, but data of only 1210 cases are accessible till follow-up. We classified the patients based on the exposure levels of SQABC. When comparing the results between all exposure and non-exposure groups, significant differences were identified, both during hospitalization and follow-ups. During hospitalization, cardiac death (4.40% vs 21.55%, P < 0.05) and cardiac shock (3.04% vs 11.62%, P < 0.05) were significantly lower in the exposure group than the non-exposure group. Similarly, during the follow-up, cardiac death (12.04% vs 20.49%, P < 0.05), acute heart failure (7.27% vs 11.81%, P < 0.05), composite endpoint of reinfarction and stroke (9.11% vs 15.28%, P < 0.05), and rehospitalization due to angina (25.49% vs 34.38%, P < 0.05) were significantly lower in the exposure group than the non-exposure group.
Conclusion: Our findings suggest that SQABC can significantly benefits the subjects in the management of high-risk AMI in them.
