Could Chinese herbal medicine truly amended the prognosis of patients with acute myocardial infarction? According to the CTS-AMI, that is precisely the case.
Presented astatine the American Heart Association 2022 Scientific Sessions, results of the CTS-AMI trial, which assessed usage of tongxinluo compared against placebo therapy successful patients with ST-elevated myocardial infarction (STEMI), bespeak usage of the accepted herbal compound was associated with a 36% simplification successful comparative hazard of large adverse cardiac and cerebrovascular events, with a comparable simplification observed for the aforesaid endpoint astatine 1-year.
“These findings enactment the usage of tongxinluo, arsenic an adjunct therapy, successful treating STEMI, astatine slightest successful China and different processing countries,” wrote investigators.
A accepted Chinese medicine compound with approvals dating backmost to 1996 successful China for angina and stroke, a renewed involvement successful inferior of tongxinluo has grown since the proof-of-concept ENLEAT proceedings demonstrated usage could accelerate ST conception solution and minimize myocardial infarction size. With this successful mind, Yang and a squad of colleagues sought to research whether oregon not tongxinluo could amended objective outcomes successful patients with acute STEMI.
To bash so, the China Tongxinluo Study for myocardial extortion successful patients with Acute Myocardial Infarction (CTS-AMI) proceedings was designed arsenic a multicenter randomized, double-blinded, placebo-controlled proceedings with the purpose of enrolling patients wrong 24 hours of presumption to either tongxinluo oregon the aforesaid doses of placebo. For the intent of analysis, tongxinluo was administered with a loading dose of 8 capsules connected time 1, followed by 4 capsules 3 times a time until 12 months. Investigators noted some the attraction and power radical received different guideline-directed STEMI treatments.
The superior result of involvement for the survey was 30-day large adverse cardiovascular and cerebrovascular events (MACCE), which was defined arsenic a composite of cardiac death, myocardial reinfarction, emergent coronary revascularization, and stroke. The proceedings besides included a multitude of secondary outcomes, specified arsenic each constituent of the superior extremity point, 30-day terrible STEMI complications, 1-year MACCE, rehospitalization owed to bosom failure, all-cause mortality, and large bleeding.
A full of 4094 patients were registered and screened. Of these, 3777 underwent randomization and were included successful the investigators’ analysis, with 1889 randomized to tongxinluo and 1888 randomized to placebo. Investigators noted determination were nary large between-group differences observed regarding baseline characteristics, emergent reperfusion therapy (87.67% successful tongxinluo radical vs 86.28% successful placebo group; P=.21), and different aesculapian treatments.
Upon analysis, results indicated a superior result lawsuit occurred among 3.39% of patients receiving tongxinluo and 5.24% of patients receiving placebo therapy (Relative Risk [RR], 0.64 [95% CI, 0.47-0.88]; P=.006). When assessing idiosyncratic components of the superior outcome, results indicated usage of tongxinluo was associated with a simplification successful 30-day cardiac decease (RR, 0.70 [95% CI, 0.50-0.99]; P=.04), 30-day myocardial reinfarction (RR, 0.35 [95% CI, 0.13-0.99]; P=.003), and 30-day changeable (RR, 0.44 [95% CI, 0.14-1.43]; P=.161).
Further investigation suggested usage of tongxinluo was associated with simplification successful 1-year MACCE (HR, 0.64 [95% CI, 0.49-0.82]; P <.001), 1-year cardiac decease (HR, 0.73 [95% CI, 0.55-0.97]; P=.03), 1-year myocardial reinfarction (HR, 0.26 [95% CI, 0.10-0.67]; P=.005), and 1-year changeable (HR, 0.44 [95% CI, 0.21-0.92]; P=.03). Analysis of information endpoints demonstrated determination was nary important quality successful 1-year all-cause mortality oregon large bleeding astatine 30 days and 1 twelvemonth compared with placebo therapy.
This study, “The Impact of Chinese Herbal Medicine, Tongxinluo successful Patients With Acute Myocardial Infarction—Results From the CTS-AMI Trial,” was presented astatine AHA 22.
