Insights
Shengmai injection (SM) demonstrates significant protective effects against experimental acute cardiogenic shock. This study highlights SM
Area of Science:
- Cardiovascular Research
- Pharmacology
- Experimental Medicine
Context:
- Acute cardiogenic shock poses a critical threat to cardiovascular health.
- Understanding protective mechanisms is vital for developing effective treatments.
Purpose:
- To investigate the cardioprotective effects of Shengmai injection (SM).
- To elucidate the underlying mechanisms of SM's action in experimental acute cardiogenic shock.
Summary:
- The study utilized a canine model of acute cardiogenic shock induced by coronary artery ligation.
- Hemodynamic parameters, cardiac enzymes (LDH, CK), oxidative stress markers (SOD, MDA), and infarct size were assessed.
- Shengmai injection treatment significantly improved hemodynamic function, reduced myocardial damage, and modulated biochemical markers.
Impact:
- Results indicate Shengmai injection possesses significant therapeutic potential for acute cardiogenic shock.
- This research provides a basis for further clinical investigation of SM in managing heart conditions.
- The findings contribute to the understanding of pharmacological interventions in cardiovascular emergencies.
Objective:
To study the protective effects and the possible mechanism of shengmai for injection(SM) against the experimental acute cardiogenic shock.
Method:
The experimental acute cardiogenic shock model was established by ligating the anterior descending cornonary in dogs. The effects of SM on cardiogenic shock were investigated by measuring the hemodynamics parameter, the activity of LDH, CK, SOD and the contents of MDA in blood serum.
Result:
In the dogs treated with SM, the mean arterial pressure (MAP), heart rate (HR), left ventricular pressure (LVP), the maximum of its first derivative (+/- dp/dtmax), the cardiac output (CO) and the cardiac index (CI) were increased significantly. The left ventricular end diastolic pressure (LVEDP) and the peripheral vascular resistance (TPVR) were decreased significantly, the myocardial infarct size was redused observely. In addition, the activity of LDH, CK and the contents of MDA in serum were decreased significantly, however the activity of SOD was increased observely.
Conclusion:
The results indicate that SM has the protective effects on cardiogenic shock.
