RESUMEN
Background: Acute myocardial infarction (AMI) is the leading cause of malignant arrhythmia, heart failure, and sudden death. However, safe and effective drugs for the treatment of AMI are unavailable to date. The present study aimed to investigate the role of traditional Chinese medicine shen-yuan-dan (SYD) in hypoxia-induced cardiomyocyte apoptosis in neonatal rats. In addition, the study explored the possible mechanism through which SYD could reduce myocardial ischemia apoptosis and regulate the expression of the miR-24/Bim pathway. Methods: Hypoxia-induced neonatal rat cardiomyocytes were used for the experiments. These cardiomyocytes were transfected with an miR-24 mimic and an miR-24 inhibitor and then cocultured with SYD-containing serum. MTT and lactate dehydrogenase (LDH) assays, AnnexinV/PI double staining, flow cytometry, and TUNEL staining were used to determine the cell viability and apoptosis under hypoxic conditions. Furthermore, the expression level of Bim in the hypoxia-induced cardiomyocytes was determined through western blotting and quantitative real-time polymerase chain reaction. Results: After 48 h of hypoxia, LDH and creatine phosphokinase (CPK) activities increased, cell viability decreased, and miR-24 expression upregulated in the cardiomyocytes. SYD alleviated hypoxia-induced cardiomyocyte injury, decreased LDH and CPK activities, increased cell viability, and reduced apoptosis in the neonatal rat cardiomyocytes. Moreover, SYD could upregulate miR-24 expression and downregulate Bim expression. Upregulation of miR-24 expression significantly enhanced the effect of SYD, thereby improving myocardial cell apoptosis. Dual-luciferase reporter assay and western blot analysis confirmed that Bim was a direct target of miR-24. Conclusion: SYD treatment reduces hypoxia-induced myocardial apoptosis by upregulating miR-24 expression. This study provides new insights into the molecular mechanism underlying the therapeutic potential of SYD in promoting the recovery of myocardial function and delaying the incidence of heart failure.
RESUMEN
This study investigated the therapeutic efficacy of Bu-Shen-Jiang-Ya decoction (BSJYD) on hypertensive renal damage to determine whether it regulates the expression of transforming growth factor-ß (TGF-ß)/SMADs signaling pathways, thereby relieving renal fibrosis in Dahl salt-sensitive (SS) rats. Dahl SS rats on a high-sodium diet were prospectively treated with BSJYD (n = 12) or valsartan (n = 12) for 8 weeks. The blood pressure (BP) of these rats was measured and their kidneys were subjected to biochemical analysis, including serum creatinine (Scr) and blood urea nitrogen (BUN); hematoxylin and eosin staining; Masson trichrome staining; real-time polymerase chain reaction; and western blot analysis. The primary outcome was that BSJYD significantly reduced BP, debased BUN, and Scr and ameliorated renal pathological changes. As underlying therapeutic mechanisms, BSJYD reduces TGFß1 and Smad2/3 expression and suppresses renal fibrosis, as suggested by the decreased expression of connective tissue growth factor(CTGF). These data suggest that BSJYD acts as an optimal therapeutic agent for hypertensive renal damage by inhibiting the TGF-ß/SMADs signaling pathway.

BACKGROUND: Xiao Yao San (XYS) is thought to be beneficial for the treatment of hypertension in China. PURPOSE: A systematic review and meta-analysis was performed to evaluate the efficacy and safety of XYS in hypertension. STUDY DESIGN: A comprehensive literature search was conducted in 7 electronic databases for randomized controlled trials from their inception until January 7, 2019. METHODS: Methodological quality was assessed independently using the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: A total of 17 trials including 1460 hypertensive patients met the selection criteria. Pooled analysis favored XYS plus antihypertensive drugs on blood pressure (BP), Hamilton anxiety scale, self-rating anxiety scale, self-rating depression scale, 9-item patient health questionnaire scale, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, homocysteine, and C-reactive protein. No significant difference between XYS plus antihypertensive drugs and antihypertensive drugs on major cardiovascular and cerebrovascular events was identified. XYS was well tolerated in the treatment of hypertension. CONCLUSION: XYS adjuvant to antihypertensive drugs maybe beneficial for hypertensive patients in lowering BP, improving depression, regulating blood lipids, and inhibiting inflammation. However, the efficacy and safety of XYS are still uncertain due to methodological shortcomings. More long-term, randomized, double-blinded clinical trials are needed in future studies.

We systematically assess the current clinical evidence of Gualouxiebaibanxia (GLXBBX) decoction for the treatment of angina pectoris (AP). We included RCTs testing GLXBBX against conventional drugs and GLXBBX combined with conventional drugs versus conventional drugs. 19 RCTs involving 1730 patients were finally identified, and the methodological quality was evaluated as generally low. The results of the meta-analysis showed that GLXBBX alone had significant effect on improving angina symptoms (RR: 1.24, 95% CI 1.14 to 1.35; P < 0.00001), ECG (RR: 1.28 [1.13,1.44]; P < 0.0001), and HDL-C (MD: 0.56 [0.54,0.58]; P < 0.00001) compared with anti-arrhythmic drugs. A significant improvement in angina symptoms (RR: 1.17 [1.12,1.22]; P < 0.00001) and ECG (RR = 1.22; 95% CI = [1.14,1.30]; P < 0.00001) was observed for GLXBBX plus conventional drugs when compared with conventional drugs. Eight trials reported adverse events without serious adverse effects. GLXBBX appears to have beneficial effects on improvement of ECG and reduction of angina symptoms in participants with AP. However, the evidence remains weak due to the poor methodological quality of the included studies. More rigorous trials are needed to confirm the results.
RESUMEN
BACKGROUND: To systematically assess the current clinical evidence of Zhigancao (ZGC) Decoction for premature ventricular contractions (PVCs). SEARCH STRATEGY: PubMed, the Cochrane Center Controlled Trials Register, EMBASE, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wanfang Med Online Database were searched until June 2014. We included randomized clinical trials testing ZGC Decoction against anti-arrhythmic drugs, ZGC Decoction combined with anti-arrhythmic drugs versus anti-arrhythmic drugs alone. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. A meta-analysis of improving total effects and reducing number of ventricular premature beats was performed to evaluate the effects of ZGC Decoction on PVCs. RESULTS: A total of 25 studies (involving 2441 patients) were included. The methodological quality of the included trials was evaluated as generally low. The results of the meta-analysis showed that ZGC Decoction combined with anti-arrhythmic drugs had significant effect on improving total effects (RR: 1.30 [1.22, 1.38]; P<0.00001) and relieving number of ventricular premature beats (MD: -6.66 [-12.94, -0.37]; P=0.04) compared with anti-arrhythmic drugs alone. Our review showed that ZGC Decoction was more effective in improving total effects (RR: 1.22 [1.08, 1.37]; P=0.0009), compared with anti-arrhythmic drugs alone. 13 trials reported adverse events, while the others did not mention them, indicating that the safety of ZGC Decoction remains uncertain. CONCLUSIONS: ZGC Decoction appears to have beneficial effects on improvement of total effects, reduction of number of ventricular premature beats in participants with PVCs. However, further thorough investigation, large-scale, proper study designed, randomized trials of ZGC Decoction for PVCs will be required to justify the effects reported.

BACKGROUND: Complementary and alternative medicine (CAM) is commonly used in China for the management of coronary artery disease (CAD). However, few studies have been conducted to investigate the prevalence, perceived effectiveness, types, and reasons of CAM use in patients diagnosed with CAD. METHODS: A cross-sectional study design was adopted. Questionnaires were distributed at the outpatient cardiac clinics of four tertiary-level teaching general hospitals in Beijing. Quantitative data were analyzed using Student's t-test. Categorical data were analyzed using chi-square test. Logistic regression was employed to explore factors associated with the use of CAM as well as CAM use features in Chinese medicine (CM) hospitals when significant differences were found upon comparisons. RESULTS: From May to July, 2009, a total of 600 questionnaires were distributed, and 546 patients with a diagnosis of CAD responded with valid values and were included in the present study. CAM was used by 69.1% of the patients with CAD; the majority (75.9%) of these CAM users believes that CAM is effective. "Few side effects" (49.6%) was the main reason of CAM use; whereas "doubt of effect" (61.5%) was the main reason for non-use. Patent herbal medicine (90.7%) was the most commonly used CAM type. Compared with non-CAM users, CAM users tended to be older (p < 0.01), have a longer disease duration (p = 0.02) and better current health status. In addition, CAM users had significant lower odds for emergency admission and hospitalization within the past one year. Patients with CAD from CM and WM hospitals differ in CAM use frequency, types, perceived effectiveness, as well as reasons for CAM use or non-CAM use. CONCLUSION: The present study suggested a group of significant factors which could influence the use of CAM in patients with CAD. CAM use patterns differ in patients from CM and WM hospitals.

Hypertension is a major public-health issue. Much consensus has been reached in the treatment, and considerable progress has been made in the field of antihypertensive drugs. However, the standard-reaching rate of blood pressure is far from satisfaction. Considering these data and the seriousness of the effects of hypertension on the individual and society as a whole, both economically and socially, physicians must look for more effective and alternative ways to achieve the target blood pressure. Could treatment of hypertension be improved by insights from traditional Chinese medicine? As one of the most important parts in complementary and alternative therapies, TCM is regularly advocated for lowering elevated blood pressure. Due to the different understanding of the pathogenesis of hypertension between ancient and modern times, new understanding and treatment of hypertension need to be reexplored. Aiming to improve the efficacy of Chinese herbal medicine in treating hypertension, the basis of treatment is explored through systematically analyzing the literature available in both English and Chinese search engines. This paper systematically reviews the trends in emerging therapeutic strategies for hypertension from the perspective of traditional Chinese medicine.
RESUMEN
We evaluated the effects of the Xuefu Zhuyu capsule (XFZY) and the Shengmai capsule (SM) on the evolution of syndromes and inflammatory markers in patients with unstable angina pectoris (UAP) after percutaneous coronary intervention (PCI). Ninety patients with UAP after PCI were randomly and equally assigned to three groups: the XFZY group, the SM group, and the placebo group, with 30 patients in each group. Six syndrome factors (including Qi deficiency, yin deficiency, yang deficiency, blood stasis, phlegm, and Qi stagnation) and 4 inflammatory markers (high-sensitivity C-reactive protein (Hs-CRP), endothelins-1 (ET-1), matrix metalloproteinases-9 (MMP-9), and homocysteine (Hcy)) were observed at week 0 and at the 1st, 4th and 12th weeks. In conclusion, the evolution of syndromes present in patients with UAP after PCI followed these trends (1) The deficiency syndromes gradually increased during a 12-week period, but the excess syndromes first gradually decreased and then mildly increased after PCI. (2) XFZY and SM can prevent excess syndromes from increasing in the later stages and prevent deficiency syndromes from increasing in all stages. (3) XFZY and SMcan reduce the levels of the inflammatory markers, especially in the later stages after PCI.
RESUMEN
Objectives. To assess the clinical effectiveness and adverse effects of Zhen Gan Xi Feng Decoction (ZGXFD) for essential hypertension (EH). Methods. Five major electronic databases were searched up to August 2012 to retrieve any potential randomized controlled trials designed to evaluate the clinical effectiveness of ZGXFD for EH reported in any language, with main outcome measure as blood pressure (BP). Results. Six randomized trials were included. Methodological quality of the trials was evaluated as generally low. Four trials compared prescriptions based on ZGXFD with antihypertensive drugs. Meta-analysis showed that ZGXFD was more effective in BP control and TCM syndrome and symptom differentiation (TCM-SSD) scores than antihypertensive drugs. Two trials compared the combination of modified ZGXFD plus antihypertensive drugs with antihypertensive drugs. Meta-analysis showed that there is significant beneficial effect on TCM-SSD scores. However, no significant effect on BP was found. The safety of ZGXFD is still uncertain. Conclusions. ZGXFD appears to be effective in improving blood pressure and hypertension-related symptoms for EH. However, the evidence remains weak due to poor methodological quality of the included studies. More rigorous trials are warranted to support their clinical use.
RESUMEN
Background. Yangxue Qingnao granule (YQG) combined with antihypertensive drugs, a new integrative medicine therapy, has been widely used for essential hypertension (EH) in China. This study aims to assess the current clinical evidence of YQG combined with antihypertensive drugs for EH. Methods. Randomized controlled trials(RCTs) published between 1996 and 2012 on YQG combined with antihypertensive drugs versus antihypertensive drugs in treating EH were retrieved from six major electronic databases, including The Cochrane Library, PubMed, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, Chinese Biomedical Literature Database, and Wanfang Data. Meta-analysis was performed on the overall effects on blood pressure. Results. Twelve randomized trials were included. Methodological quality of the trials was evaluated as generally low. Meta-analysis showed that YQG combined with antihypertensive drugs demonstrated potential effect for lowing either SBP (MD: -7.31 [-11.75, -2.87]; P = 0.001) or DBP (MD: -5.21 [-8.19, -2.24]; P = 0.0006) compared to antihypertensive drugs alone. Conclusions. It indicated that YQG combined with antihypertensive drugs is more effective than antihypertensive drugs alone in treating EH. However, more RCTs of larger scale, multicentre/country, longer follow-up periods, and higher quality are required to verify the efficacy of integrative medicine therapy over all antihypertensive therapies.
RESUMEN
Objectives. The study was to investigate the effects and mechanisms of Shen-Yuan-Dan (SYD) pharmacological postconditioning on myocardial ischemia/reperfusion (I/R) injury. Methods. In the in vivo experiment, myocardial injury markers and histopathology staining were examined. In the in vitro experiment, cell viability and cell apoptosis were, respectively, detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays and Hoechst 33342 fluorochrome staining. The protein expressions of Bcl-2 and Bax were determined by immunocytochemistry assay. Results. Both low and high doses of SYD protected myocardium against I/R injury in rat model by reducing lactic dehydrogenase (LDH) and creatine kinase-MB (CK-MB) activity and malondialdehyde (MDA) content, increasing superoxide dismutase (SOD) activity and attenuating histopathology injury. Meanwhile, in the in vitro experiment, SYD promoted cell viability and inhibited the cardiomyocyte apoptosis. The level of Bcl-2 protein was restored to the normal level by SYD pharmacological postconditioning. In contrast, the Bax protein level was markedly reduced by SYD pharmacological postconditioning. These effects of SYD were inhibited by LY294002. Conclusions. The results of this study suggested that SYD pharmacological postconditioning has protective effects against myocardial I/R injury in both in vivo and in vitro models, which are related to activating the phosphatidylinositol 3-kinase/Akt (PI3K/Akt) pathway.
RESUMEN
Occidental medicine has a given definition for restless legs syndrome (RLS) and knowledge of RLS pathophysiology has led to the development of its therapeutic management. RLS has no cure. Many methods have been used for its treatment, among which traditional Chinese medicine (TCM) has been considered as a new approach. However, description and management of the disease symptoms can be found in Chinese ancient medical systems. The first mention of RLS may have been as early as the third century BC described as "leg uncomfortable". Nonetheless, the lack of a complete description encompassing all four modern cardinal features of RLS makes this uncertain. On the other hand, the first description of RLS encompassing three of the four major modern criteria occurs in the ancient book of Neike Zhaiyao (Internal summary), 1529 AD just about a century and a half prior to the description of RLS by Sir Thomas Willis in England. Here, we introduce the philosophical concepts of traditional Chinese medicine and the description, classification and understanding of RLS symptoms in traditional Chinese medicine. We have conducted an in-depth review of the literature reporting one part of TCM, Chinese herbal treatment efficacy for RLS, through both English and Chinese search engines. Eighty-five studies were included in the review and more than 40 formulas (including 176 different ingredients) were found in the literature. According to the literature, Chinese herbs have been demonstrated to be safe and hold great potential to be an effective treatment modality for RLS, but the evidence is limited by the quality of these studies. Of the eighty-five studies, only nine were clinical trials with a control group and only three of them were randomized. In cases where herbal preparations were compared to Western medications for RLS, the herbal preparations appear to be superior. However, uncertainty as to whether the diagnosis of RLS was made in accord with Western norms and the use of homemade non-validated rating scales create uncertainty as to the meaning of these results. High-quality randomized and double blinded clinical trials of Chinese herbs in treating RLS will be required in the future. This review highlights aspects of Chinese herbal treatment important to guide future research and clinical practice. To our knowledge, this is the first systematic English review of the role of Chinese herbs in the treatment of RLS.

Objectives. To assess the current clinical evidence of Banxia Baizhu Tianma Decoction (BBTD) for essential hypertension (EH). Search Strategy. Electronic databases were searched until July 2012. Inclusion Criteria. We included randomized clinical trials testing BBTD against placebo, antihypertensive drugs, or combined with antihypertensive drugs against antihypertensive drugs. Data Extraction and Analyses. Study selection, data extraction, quality assessment, and data analyses were conducted according to Cochrane standards. Results. 16 randomized trials were included. Methodological quality of the included trials was evaluated as generally low. 2 trials compared prescriptions based on BBTD using alone with antihypertensive drugs. Meta-analysis showed no significant effect of modified BBTD compared with captopril in systolic blood pressure (MD: -0.75 (-5.77, 4.27); P = 0.77) and diastolic blood pressure (MD: -0.75 (-2.89, 1.39); P = 0.49). 14 trials compared the combination of BBTD or modified BBTD plus antihypertensive drugs with antihypertensive drugs. Meta-analysis showed there are significant beneficial effect on systolic blood pressure in the combination group compare to the antihypertensive drugs (MD: -4.33 (-8.44, -0.22); P = 0.04). The safety of BBTD is uncertain. Conclusions. There is encouraging evidence of BBTD for lowering SBP, but evidence remains weak. Rigorously designed trials are warranted to confirm these results.

OBJECTIVE: Compared with Shengmai Capsule (çèè¶å, SM), the study was conducted to evaluate the efficacy and safety of Xuefu Zhuyu Capsule (è¡åºéçè¶å, XFZY) on the symptoms and signs and health-related quality of life (HR-QOL) in the unstable angina (UA) patients with blood-stasis syndrome (BSS) after percutaneous coronary intervention (PCI). METHODS: A randomized, double-blinded, double-dummy, and placebo-controlled trial was applied. Ninety patients, diagnosed as UA and BSS after successful PCI, were enrolled and equally randomized into three groups, XFZY group, SM group, and placebo group, and administered with the corresponding medications respectively for four weeks. The clinical symptoms and signs (CSS), electrocardiography (ECG), and BSS scores were recorded and compared among groups during and after the treatment. Short-form 36 (SF-36) and Seattle Angina Questionnaire (SAQ) were applied to assess the HR-QOL in each group before and after the treatment. Safety indexes (blood routine and liver and kidney function tests) were also examined at the beginning and after the treatment. RESULTS: Eighty-six patients completed the whole study. After the treatment, the total effective rates of the XFZY group in ameliorating CSS and ECG were 76.7% and 60.0%, respectively, which were obviously higher than those in SM (CSS: 53.3%; ECG: 36.7%) and the placebo (CSS: 43.3%; ECG: 30.0%) groups. After one week's treatment, BSS scores slightly decreased in each group, but no significant differences were found among three groups (P>0.05). After four weeks' treatment, BSS scores in the XFZY group decreased to a lower level compared with SM (P <0.05) and the placebo (P <0.01) groups. After the treatment, the efficacy of XFZY group in improving body pain (BP), general health (GH), vitality (VT), society functioning (SF), role emotional (RE), angina stability (AS), angina frequency (AF), and treatment satisfaction (TS) were better than those in the placebo group (P <0.05,P <0.01). Meanwhile, the dimensions of BP, GH, SF, AS, AF, and TS were better improved than those in the SM group P <0.05). No obvious adverse reaction was found during and after the treatment except one case in the XFZY group reporting of stomach discomfort. CONCLUSIONS: Compared with SM Capsule treatment, a short-term treatment with XFZY Capsule exhibits better efficacy on CSS and BSS scores, and HR-QOL in UA patients with BSS after PCI. However, its long-term efficacy and safety still needs further investigation.

OBJECTIVE: To observe the effect of Yiqi Yangyin Decoction (, YQYYD) on the quality of life (QOL) of patients with unstable angina pectoris (UAP). METHODS: A total of 108 patients with UAP of qi-yin deficiency syndrome confirmed by coronary angiography were enrolled and assigned to the treated group (treated with YQYYD and conventional therapy of Western medicine) and the control group (treated with conventional therapy of Western medicine), by the use of the PROC PLAN of the SAS 6.12 software, in a prospective, randomized, controlled design. The clinical total effective rate, symptom score, QOL scale [Seattle Angina Questionnaire (SAQ)] and incidence of important clinical events were defined as the observation indices to evaluate the interventional effect of YQYYD on the QOL of patients with UAP of the qi-yin deficiency syndrome. RESULTS: During the study, three cases dropped out in the treated group, one case dropped out in the control group, and 104 cases, including 51 cases in the treatment group and 53 cases in the control group, finished the trial. After four weeks of treatment, the total clinical effective rates in the treated group and the control group were 80.4% and 75.5% respectively, and there was no obvious difference between them (P>0.05). However, the symptom score of the treated group (9.31 + or - 2.02) was significantly lesser than that of the control group (11.62 + or - 3.04, P<0.05), and the total score of the QOL scale of the treated group (68.76 + or - 5.74) was significantly higher than that of the control group (61.06 + or - 3.31, P<0.01). Among those in the treated group physical limitation, angina stability, angina frequency, and treatment satisfaction were significantly ameliorated when compared with the control group after treatment (P<0.05, P<0.01). The incidence of important clinical events in the treated group (3.9%) was lower than that in the control group (5.7%) during the 8-month follow-up period, but the difference was insignificant (P>0.05). CONCLUSION: YQYYD could improve the clinical symptoms of patients with UAP of qi-yin deficiency syndrome and greatly improve their QOL.

BACKGROUND: With the wide application of percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD), it is a popularly concerned problem within clinical doctors to promote the patients' early recovery and improve their health related quality of life (HR-QoL). OBJECTIVE: To evaluate the efficacy and safety of Xuefu Zhuyu (XFZY) Capsule, a compound traditional Chinese herbal medicine for activating blood circulation, in improving HR-QoL in unstable angina (UA) patients with blood-stasis syndrome after PCI, and to make a comparison with Shengmai (SM) Capsule. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: The study was performed at Rescue Center of Emergency, Beijing Anzhen Hospital, China Capital University of Medical Science from March 2008 to February 2009. Using a randomized, double-blinded, double-dummy and placebo controlled study design, ninety patients diagnosed as UA and concomitant blood stasis syndrome after successful PCI therapy were enrolled and randomized into three groups: XFZY group, SM group and placebo group, and the patients were administered with the corresponding medications for 4 weeks. MAIN OUTCOME MEASURES: The Short-Form 36 (SF-36) and Seattle Angina Questionnaire (SAQ) were applied to assess the HR-QoL in each group before and after the treatment. RESULTS: A total of 90 patients were recruited and 4 cases of them withdrew from the study during the treatment period indicating a 4.4% of dropping rate. After the treatment, several domains of scores in SF-36 and SAQ were significantly increased in three groups (P<0.05, P<0.01). The efficacy of XFZY Capsule in improving body pain (BP), general health (GH), vitality (VT), social function (SF), role emotional (RE), angina stability (AS), angina frequency (AF), as well as treatment satisfaction (TS) was better than that of placebo (P<0.05, P<0.01). Meanwhile, the dimensions of BP, GH, SF, AS, AF, TS were improved as compared with those in the SM group (P<0.05). No obvious adverse reaction was found during and after the treatment with the exception of one case in XFZY group reporting of discomfort in the stomach. CONCLUSION: Compared with SM Capsule, a short-term treatment of XFZY Capsule exhibits better efficacy in improving HR-QoL in UA patients with blood-stasis syndrome after PCI. However, its long-term efficacy and safety needs further investigation. TRIAL REGISTRATION: ClinicalTrials.gov Identifier, NCT00817024.

OBJECTIVE: Recently, a new traditional Chinese medicine differentiation theory "Syndrome Element (SE)" has been raised. In this study, the main syndrome element types and their correlations with the results of coronary angiography (CAG) in patients with coronary heart disease (CHD) were investigated. METHODS: Epidemiology cross-sectional study method was employed and 324 patients with CHD were enrolled, and their syndrome element types as well as the CAG results were analyzed. The correlations among syndrome element types, Gensini score, and the number of abnormal branches were also analyzed based on the distribution characteristics of syndrome element and coronary angiography results in the 324 cases. RESULTS: According to their occurrence frequency in 324 CHD patients, the top eight major heart syndrome elements were Xin () blood stasis (85.8%), Xin qi deficiency (79.6%), Xin heat blockage (41.1%), Xin phlegm with turbid fluid (38.0%), Xin qi stagnation (24.7%), Xin yang deficiency (18.9%), Xin yin deficiency (17.5%) and Xin cold coagulation (4.4%), respectively, which suggested that Xin blood stasis and Xin qi deficiency were the two most common syndrome elements. Also, as coronary artery Gensini score increased, the changing trend of the syndrome element was "Xin yang deficiency with blood stasis" to "Xin phlegm obstruction with heat blockage" to "Xin yin deficiency with blood stasis" to "Xin qi deficiency with blood stasis" to "Xin cold coagulation with phlegm and turbid fluid, "Xin cold coagulation with blood stasis" to "Xin deficiency of qi, yin and yang". As the number of abnormal branches increased, the syndrome element changing trend was "simultaneous occurrence of cold and heat syndrome" to "Xin qi and yang deficiency with blood stasis" to "Xin retention of phlegm with turbid fluid" to "Xin cold coagulation in the heart meridian", "Xin deficiency of both qi and yin". The result of this study shows that Xin qi deficiency and Xin blood stasis were the major syndrome elements in patients with CHD. CONCLUSION: As the severity and extent of coronary artery lesion increased, there were some apparent correlations among syndrome elements, Gensini score and number of abnormal coronary artery branches.
