Insights
Xinkeshu Tablet (XKS) improved heart rate variability (HRV) and reduced angina episodes in coronary heart disease (CHD) patients. Metoprolol also showed benefits, but XKS demonstrated more significant improvements in certain HRV frequency-domain indexes.
Area of Science:
- Cardiology
- Pharmacology
- Medical Research
Context:
- Coronary heart disease (CHD) poses significant cardiovascular risks.
- Heart rate variability (HRV) is a crucial indicator of autonomic nervous system function in cardiovascular health.
- Traditional treatments for CHD aim to manage symptoms and improve cardiac function.
Purpose:
- To investigate the therapeutic effect of Xinkeshu Tablet (XKS) on HRV in patients diagnosed with CHD.
- To compare the efficacy of XKS with Metoprolol, a standard beta-blocker, in managing CHD symptoms and HRV.
Summary:
- Sixty CHD patients were randomized to receive either XKS or Metoprolol alongside conventional treatment for 8 weeks.
- Both groups experienced a reduction in angina pectoris episodes and a decrease in average heart rate.
- Xinkeshu Tablet (XKS) treatment resulted in more significant improvements in specific frequency-domain HRV indexes compared to Metoprolol.
Impact:
- Xinkeshu Tablet (XKS) demonstrates potential as an adjunctive therapy for improving autonomic function in CHD patients.
- The findings suggest XKS may offer superior benefits in modulating cardiac autonomic balance compared to Metoprolol.
- This study contributes to understanding novel therapeutic strategies for managing coronary heart disease.
Objective:
To evaluate the effect of Xinkeshu Tablet (XKS) on heart rate variability (HRV) in patients with coronary heart disease (CHD).
Methods:
Sixty patients with their diagnosis of CHD confirmed by coronary angiography were randomized into two groups equally. Besides the conventional treatment for CHD, XKS and Metoprolol were given respectively to patients in the treated group and the control group for 8 weeks. Symptoms and 24 h dynamic ECG were observed before and after treatment.
Results:
Episode of angina pectoris decreased obviously in both groups after treatment, from 8.8 +/- 3.2 times per week (the same hereafter) to 4.4 +/- 2.1 in the treated group (P<0.05), and from 8.4 +/- 3.1 to 3.9 +/- 2.0 in the control group (P <0.05). HRV analysis showed that after treatment the average heart rate lowered from 85.44 +/- 2.89 beat/min to 77.32 +/- 2.17 beat/min in the treated group and from 83.80 +/- 4.30 beat/min to 76.70 +/- 2.93 beat/min in the control group (both P < 0.05), showing no significant difference in extent of lowering between groups (P > 0.05). The time-domain indexes elevated in both groups, showing no statistical difference between groups (P >0.05). As for the frequency-domain indexes, low frequency (LF), high frequency (HF) and total power raised, while LF/HF and very low frequency lowered in both groups, but the changes were more significant in the treated group (P <0.05).
Conclusion:
XKS could improve HRV in patients of CHD and reduce the episode of angina pectoris in them.

Cardiac 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...
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
