Insights

Shuxinyin (SXY) therapy improved early left ventricular diastolic function in coronary heart disease patients. This traditional Chinese medicine treatment alleviated symptoms and improved echocardiographic measures of diastolic filling.

Area of Science:

  • Cardiology
  • Traditional Chinese Medicine
  • Cardiovascular Research

Background:

  • Abnormal left ventricular diastolic function is prevalent in coronary heart disease (CHD), leading to symptoms like dyspnea and chest distress, potentially progressing to heart failure.
  • Pulsed Doppler echocardiography is a key tool for assessing left ventricular diastolic function.
  • Traditional Chinese Medicine (TCM) offers potential therapeutic avenues for cardiovascular conditions.

Purpose of the Study:

  • To investigate the effects of Shuxinyin (SXY), a TCM herbal formula, on left ventricular diastolic function in patients with CHD.
  • To evaluate the impact of SXY therapy on clinical symptoms, electrocardiographic findings, and plasma lipoprotein levels.
  • To assess changes in Doppler echocardiographic parameters indicative of diastolic function.

Main Methods:

  • A study involving 31 patients diagnosed with coronary heart disease and abnormal left ventricular diastolic function.
  • Treatment administered: Shuxinyin (SXY), a herbal formula focused on tonifying Qi and Yin, for one month.
  • Assessment methods included clinical evaluation of symptoms and signs, electrocardiography (ECG), plasma lipoprotein analysis, and pulsed Doppler echocardiography.

Main Results:

  • SXY therapy resulted in significant improvement in clinical symptoms and ECG findings, with a symptomatic effective rate of 87.1%.
  • Plasma lipoprotein levels were significantly reduced (P < 0.05) after SXY treatment.
  • Doppler echocardiography revealed significant increases in the peak E wave, E wave area, and deceleration rate (P < 0.01), along with a decreased A/E wave peak ratio, indicating improved early diastolic function.

Conclusions:

  • Shuxinyin (SXY) effectively improves early left ventricular diastolic function in patients with coronary heart disease.
  • The therapy enhances peak velocity and volume of rapid left ventricular filling during early diastole.
  • SXY treatment alleviates clinical symptoms and improves ECG findings associated with diastolic dysfunction in CHD.

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
