Objective

2

To comprehensively evaluate the clinical value of

Qidong Yixin Oral

Liquid

in the treatment of viral myocarditis with

qi

and

yin

deficiency syndrome.

Method

2

A Multi-Criteria Decision Analysis （MCDA） model was used to collect multi-source evidence and evaluate the value of

Qidong Yixin Oral

Liquid

across the "6+1" dimensions： safety， effectiveness， economy， innovation， suitability， accessibility， and traditional Chinese medicine （TCM） characteristics. A comprehensive clinical evaluation was then conducted.

Result

2

Safety： Evidence from passive monitoring， clinical literature， drug quality assessments， and alert management indicates that no serious adverse reactions induced by

Qidong Yixin Oral

Liquid

have been reported. Effectiveness： Guidelines recommend

Qidong Yixin Oral

Liquid

for viral myocarditis in the prolonged or chronic stage with

qi

and

yin

deficiency syndrome. Systematic reviews of randomized controlled trials suggest that， when combined with conventional treatment， the product significantly improves clinical efficacy and downregulates myocardial enzyme indicators compared with control therapy. Economy： Cost-effectiveness analysis based on creatine kinase isoenzyme reduction shows that combination therapy including

Qidong Yixin Oral

Liquid

is more economical. Innovation：

Qidong Yixin Oral

Liquid

is the first Chinese patent medicine approved in China with viral myocarditis included in its indications， demonstrating good innova

tion. Suitability： Surveys among clinicians and patients indicate good suitability for clinical use. Accessibility： The drug shows favorable accessibility， price level， and affordability. TCM characteristics： Derived from Professor REN Jixue's empirical formula against viral myocarditis， the product targets the core pathogenesis of

qi

and

yin

deficiency syndrome. It uses a heavy dose to tonify

qi

and nourish

yin

to treat the root cause， promotes

qi

circulation and clears heat to alleviate symptoms， and supports

yang

qi

to protect vulnerable areas. The TCM characteristics are prominent. The comprehensive evaluation indicates that safety and TCM characteristics are outstanding， while effectiveness， economy， innovation， suitability， and accessibility are relatively balanced. CSC v2.0 software calculations support the clinical value of

Qidong Yixin Oral

Liquid

in viral myocarditis.

Conclusion

2

Based on the comprehensive clinical evaluation，

Qidong Yixin Oral

Liquid

demonstrates good clinical value in treating viral myocarditis with

qi

and

yin

deficiency syndrome， with outstanding safety and distinctive TCM characteristics.
