Acupuncture decreased the risk of coronary heart disease by 55%

58,899 patients in both cohorts were identified. Baseline characteristics were similar in both cohorts. The cumulative incidence of coronary heart disease CHD was significantly lower in the acupuncture cohort (log-rank test, p < 0.001). In the follow-up period, 4389 patients in the acupuncture cohort (17.44 per 1000 person-years) and 8133 patients in the no-acupuncture cohort (38.36 per 1000 person-years) developed CHD (adjusted HR 0.43, 95% CI 0.41–0.45). The beneficial effect of acupuncture on the incidence of CHD was independent of age, sex, comorbidities, and statins used.
