Insights
Heart tablets enhance cardiac function by improving blood flow and reducing oxygen demand. These cardiovascular effects suggest a positive regulatory role in the heart.
Area of Science:
- Pharmacology
- Cardiovascular Physiology
Context:
- Investigating the mechanisms of traditional or novel therapeutic agents on cardiac function is crucial for understanding cardiovascular health.
- Anesthetized dogs serve as a relevant model for studying acute hemodynamic and myocardial responses.
Purpose:
- To elucidate the pharmacological effects of Heart tablets on cardiac function, hemodynamics, and myocardial oxygen consumption.
- To determine the specific impacts of Heart tablets on coronary blood flow, cardiac output, and myocardial oxygen utilization.
Summary:
- Heart tablets increased femoral arterial blood pressure and cardiac output, while decreasing total peripheral resistance.
- The tablets expanded coronary arteries and peripheral vessels, increasing coronary blood flow and improving left ventricular function.
- Significant increases in coronary vein sinus oxygen content were observed, alongside reduced myocardial oxygen consumption and utilization.
Impact:
- Heart tablets demonstrate a positive regulatory role in cardiac function by improving cardiovascular adaptability and myocardial activity.
- The findings suggest potential therapeutic applications for Heart tablets in managing conditions related to impaired cardiac function or oxygen supply.
- This study provides valuable insights into the cardiovascular benefits of Heart tablets, contributing to the field of cardiovascular pharmacology.
Objective:
To observe the pharmacological effects of Heart tablets on cardiac function and its mechanism, the effects on cardiac hemodynamics and myocardial oxygen consumption in anesthetized dogs were observed.
Method:
Observe the effect of Heart tablets on coronary blood flow, cardiac output, myocardial oxygen consumption and other indicators in normal anesthetized dogs.
Result:
The Heart tablets can increase femoral arterial blood pressure, while no effect is found on the heart rate, standard II ECG PR interval, QRS interval, QT interval, T wave and other parameters. The tablets can expand coronary artery and peripheral vessel, increase coronary blood flow, lower coronary resistance and increase cardiac blood supply capacity, improve left ventricular function, ameliorate cardiovascular adaptability, increase dp/dt(max), enhance myocardial activity and have a positive regulatory role in heart. At the meantime raise the cardiac output and stroke volume were raised, so that blood pressure can be increased, while the total peripheral resistance was decreased. The coronary vein sinus oxygen content were significantly increased and myocardial oxygen consumption index and myocardial oxygen utilization were reduced.
Conclusion:
The tablets can adjust and improve the cardiovascular system.

01:19Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...
