RESUMEN

BACKGROUND AND PURPOSE: Diabetes mellitus (DM) is a major risk factor for coronary heart disease (CHD). Previous research has reported that the Fufang-Zhenzhu-Tiaozhi (FTZ) formula has obvious effects on the treatment of dyslipidemia and hyperglycemia. In the present study, we intended to establish a convenient DM-CHD model in minipigs and investigated the protective effect of FTZ against myocardial injury and its mechanism. METHODS: The DM-CHD model was established by a high-fat/high-sucrose/high-cholesterol diet (HFSCD) combined with balloon injury in the coronary artery. Subsequently, sixteen Wuzhishan minipigs were assigned to three groups: control group, model group, and FTZ group. The model group and FTZ group were given a HFSCD, while the control group was given a normal diet (ND). FTZ was given with meals in the FTZ group. During this time, biochemical parameters, such as total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein (HDL-C), and fasting blood glucose (FBG), were measured by using testing kits. Insulin (INS) was determined by ELISA, and the homeostasis model assessment index of insulin resistance (HOMA-IR) was calculated to evaluate insulin resistance levels. After FTZ administration, the plasma levels of lactate dehydrogenase (LDH), creatine kinase isoenzyme MB (CK-MB), and cardiac troponin I (cTnI) were measured by using ELISA kits to evaluate myocardial injury. Coronary artery stenosis was analyzed by angiographic and HE staining. Myocardial ischemia was assayed with electrocardiogram (ECG). Moreover, cytokines, including interleukin-6 (IL-6), hypersensitive C-reactive protein (hs-CRP), and tumor necrosis factor-alpha (TNF-α), were measured by ELISA kits to assess inflammation. The myocardial tissue was collected, and the pathological morphology was observed by transmission electron microscopy (TEM), HE staining, and Masson staining. Western blots were used to detect the expression of PI3K, AKT, p-AKT, p-NF-κB, and NF-κB. RESULTS: A DM-CHD model in minipigs with glucose-lipid metabolism disorder, coronary artery incrassation and myocardial damage was successfully established through balloon injury in the coronary artery combined with HFSCD. FTZ effectively inhibited coronary artery incrassation and protected the myocardium against injury in DM-CHD minipigs. FTZ decreased proinflammatory cytokine levels and upregulated the protein expression of the PI3K/Akt pathway in the myocardium. CONCLUSIONS: A novel DM-CHD model in minipigs was successfully established through balloon injury in the coronary artery combined with HFSCD. FTZ has a protective effect against myocardial injury in DM-CHD by inhibiting inflammation and activating the PI3K/AKT signaling pathway.

RESUMEN

Early identification of coronary atherosclerotic pathogenic mechanisms is useful for predicting the risk of coronary heart disease (CHD) and future cardiac events. Epigenome changes may clarify a significant fraction of this "missing hereditability", thus offering novel potential biomarkers for prevention and care of CHD. The rapidly growing disciplines of systems biology and network science are now poised to meet the fields of precision medicine and personalized therapy. Network medicine integrates standard clinical recording and non-invasive, advanced cardiac imaging tools with epigenetics into deep learning for in-depth CHD molecular phenotyping. This approach could potentially explore developing novel drugs from natural compounds (i.e. polyphenols, folic acid) and repurposing current drugs, such as statins and metformin. Several clinical trials have exploited epigenetic tags and epigenetic sensitive drugs both in primary and secondary prevention. Due to their stability in plasma and easiness of detection, many ongoing clinical trials are focused on the evaluation of circulating miRNAs (e.g. miR-8059 and miR-320a) in blood, in association with imaging parameters such as coronary calcifications and stenosis degree detected by coronary computed tomography angiography (CCTA), or functional parameters provided by FFR/CT and PET/CT. Although epigenetic modifications have also been prioritized through network based approaches, the whole set of molecular interactions (interactome) in CHD is still under investigation for primary prevention strategies.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Blood-stasis syndrome (BSS) is a specific ZHENG type of coronary heart disease (CHD) in traditional Chinese medicine (TCM). The Xue-Fu-Zhu-Yu (XFZY) decoction is a common herbal formula that has been used for several centuries to treat BSS, but its mechanism has not been thoroughly elucidated to date. AIM OF THE STUDY: In this study, serum lipid, blood haemorheology and metabolomics analyses were performed to depict a complete profile of XFZY capsules for the treatment of CHD with BSS and to reveal the potential mechanism of the XFZY capsules. MATERIALS AND METHODS: A rat model of CHD with BSS was generated by combining a high-fat diet (HFD) with a left anterior descending coronary artery (LAD) ligation. After four weeks of treatment with XFZY capsules or simvastatin pills, an echocardiography was performed for a therapeutic evaluation. Blood samples and heart tissues were then collected for further analyses. A UPLC-QTOF/MS-based metabolomics analysis of the plasma was performed, and all metabolic features were fit by PCA and OPLS-DA pattern for the biomarker screen. The identified biomarkers were later implemented into a metabolic pathway analysis. Furthermore, we used qRT-PCR and Western blot analyses to verify the treatment effects of the XFZY capsules. RESULTS: A total of 49 metabolites (VIP>1.0, p < 0.05, RSD%<20%) were identified in the Model rats, and 27 metabolites (VIP>1.0, p < 0.05, RSD%<20%) were identified in the XFZY-H rats. The results of the pathway analysis indicated that the XFZY capsules treated CHD primarily by regulating cardiac energy, phospholipid, polyunsaturated fatty acid (PUFA) and amino acid metabolism. In addition, blood viscosity and serum lipid assays suggested that XFZY capsules could decrease serum triglycerides, total cholesterol, low-density lipoprotein cholesterol and whole blood viscosity at a low shear rate. CONCLUSION: This study demonstrated that the XFZY capsule effectively decreases serum lipids and whole blood viscosity in CHD with BSS. The underlying metabolic mechanism mainly included improving cardiac energy supply, reducing phospholipid peroxide, maintaining the PUFA metabolic balance and regulating amino acid metabolism.

RESUMEN

Synbiotics are known to exert multiple beneficial effects, including anti-inflammatory and antioxidant actions. The aim of this study was to evaluate the effects of synbiotic supplementation on carotid intima-media thickness (CIMT), biomarkers of inflammation, and oxidative stress in people with overweight, diabetes, and coronary heart disease (CHD). This randomized, double-blind, placebo-controlled trial was conducted and involved 60 people with overweight, diabetes, and CHD, aged 50-85 years old. Participants were randomly allocated into two groups to take either synbiotic supplements containing three probiotic bacteria spices Lactobacillus acidophilus strain T16 (IBRC-M10785), Lactobacillus casei strain T2 (IBRC-M10783), and Bifidobacterium bifidum strain T1 (IBRC-M10771) (2 × 109 CFU/g each) plus 800 mg inulin or placebo (n = 30 each group) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention period to determine metabolic variables. After the 12-week intervention, compared with the placebo, synbiotic supplementation significantly reduced serum high-sensitivity C-reactive protein (hs-CRP) (- 3101.7 ± 5109.1 vs. - 6.2 ± 3163.6 ng/mL, P = 0.02), plasma malondialdehyde (MDA) (- 0.6 ± 1.0 vs. - 0.1 ± 0.3 µmol/L, P = 0.01), and significantly increased nitric oxide (NO) levels (+ 7.8 ± 10.3 vs. - 3.6 ± 6.9 µmol/L, P < 0.001). We did not observe any significant changes of synbiotic supplementation on other biomarkers of oxidative stress and CIMT levels. Overall, synbiotic supplementation for 12 weeks among people with overweight, diabetes, and CHD had beneficial effects on serum hs-CRP, plasma NO, and MDA levels; however, it did not have any effect on other biomarkers of oxidative stress and CIMT levels.

RESUMEN

Huoxue Huayu therapy (HXHY) has been widely used to treat cardiovascular diseases in traditional Chinese medicine (TCM) such as hypertension and coronary heart disease (CHD). The present study describes a meta-analysis of a series of prospective randomized, double-blind, placebo-controlled trials conducted to evaluate the effect of HXHY on patients with CHD after percutaneous coronary intervention (PCI). The Cochrane Library, PubMed, EMBASE, the China National Knowledge Infrastructure (CNKI), the Chinese Biomedical Literature database, and the Wanfang database were searched up until June 2018. A series of randomized controlled clinical trials were included and the subjects were patients with CHD who had undergone PCI. The experimental group was treated with HXHY therapy, and the control group was treated with placebo; meanwhile, all the patients accepted conventional Western medicine. Review Manager 5.3 software was used for the statistical analysis. Ten trials were included in the final study. The overall risk of bias assessment was low. HXHY had a greater beneficial effect on reducing the in-stent restenosis (ISR) rate (RR = 0.57, 95% confidence interval [CI] [0.40-0.80], P=0.001) and the degree of restenosis (MD = -8.89, 95% CI [-10.62 to -7.17], P<0.00001) compared with Placebo. Moreover, HXHY was determined to be more effective in improving Seattle Angina Questionnaires (SAQ) and the revascularization rate (RR = 0.54, 95% CI [0.32-0.90], P=0.02) compared with Placebo, whereas the rate of death and MI of patients treated with HXHY were no different from those treated with the placebo (P>0.05). Therefore, HXHY is an effective and safe therapy for CHD patients after PCI.

RESUMEN

BACKGROUND: Dyslipidaemia is a major risk factor for coronary heart disease (CHD). Danhong and Huangqi injections, two traditional Chinese medicine prescriptions, have been widely studied regarding their lipid-lowering properties. However, the results were inconsistent and inconclusive. Thus, we conducted this meta-analysis of clinical controlled trials to clarify the lipid-lowering effects of Danhong and Huangqi injections. METHODS: The databases including PubMed, Google Scholar, Web of Science, Cochrane Library, Wanfang Database, CNKI and VIP were searched. The following information was obtained from each study: first author, age, gender, ethnicity, health condition, treatment dose, treatment duration, sample size, mean and standard deviation or standard error of lipid variables before and after treatment. The changes in lipid levels from pre- to post-treatment were calculated and compared between the control groups and the treatment groups in this meta-analysis. RESULTS: Forty-four studies (5021 subjects) and 7 studies (542 subjects) were respectively identified for Danhong and Huangqi injections. Compared with the control groups, Danhong injection yielded a significant reduction in triglycerides (TG) [standardized mean difference (SMD) = - 0.76, 95% confidence interval (CI) = (- 0.91, - 0.61), P <  0.001], total cholesterol (TC) [SMD = - 1.29, 95% CI = (- 1.56, - 1.03), P <  0.001] and low-density lipoprotein cholesterol (LDL-C) [SMD = - 0.76, 95% CI = (- 0.93, - 0.59), P <  0.001], and a significant elevation in high-density lipoprotein cholesterol (HDL-C) [SMD = 0.70, 95% CI = (0.41, 0.98), P <  0.001]. Regarding Huangqi injection, it yielded a significant reduction in TC [SMD = - 1.13, 95% CI = (- 2.09, - 0.16), P = 0.02] and marginally in TG [SMD = - 1.27, 95% CI = (- 2.53, 0.00), P = 0.05] comparing with the control groups. CONCLUSIONS: Danhong injection can effectively decrease the plasma levels of TG, TC and LDL-C, and increase HDL-C levels. Huangqi injection also has significant effects on TG and TC reduction, but not as powerful as Danhong injection.

RESUMEN

OBJECTIVES: To assess whether an additional chest ultra-low-dose CT scan to the coronary CT angiography protocol can be used for lung cancer screening among patients with suspected coronary artery disease. METHODS: 175 patients underwent coronary CT angiography for assessment of coronary artery disease, additionally undergoing ultra-low-dose CT screening to early diagnosis of lung cancer in the same scanner (80kVp and 15mAs). Patients presenting pulmonary nodules were followed-up for two years, repeating low-dose CTs in intervals of 3, 6, or 12 months based on nodule size and growth rate in accordance with National Comprehensive Cancer Network guidelines. RESULTS: Ultra-low-dose CT identified 71 patients with solitary pulmonary nodules (41%), with a mean diameter of 5.50±4.00mm. Twenty-eight were >6mm, and in 79% (n=22) of these cases they were false positive findings, further confirmed by follow-up (n=20), resection (n=1), or biopsy (n=1). Lung cancer was detected in six patients due to CT screening (diagnostic yield: 3%). Among these, four cases could not be detected in the cardiac field of view. Most patients were in early stages of the disease. Two patients diagnosed at advanced stages died due to cancer complications. The addition of the ultra-low-dose CT scan represented a radiation dose increment of 1.22±0.53% (effective dose, 0.11±0.03mSv). CONCLUSIONS: Lung cancer might be detected using additional ultra-low-dose protocols in coronary CT angiography scans among patients with suspected coronary artery disease.

RESUMEN

AIM: To analyze the serum metabolites in patients with coronary heart disease (CHD) showing dampness syndrome and patients with chronic renal failure (CRF) showing dampness syndrome and to seek the substance that serves as the underlying basis of dampness syndrome in "same syndromes in different diseases." Methods. Metabolic spectrum by GC-MS was performed using serum samples from 29 patients with CHD showing dampness syndrome and 32 patients with CRF showing dampness syndrome. The principal component analysis and statistical analysis of partial least squares were performed to detect the metabolites with different levels of expression in patients with CHD and CRF. Furthermore, by comparing the VIP value and data mining in METLIN and HMDB, we identified the common metabolites in both patient groups. RESULTS: (1) Ten differential metabolites were found in patients with CHD showing dampness syndrome when compared to healthy subjects. Meanwhile, nine differential metabolites were found in patients with CRF showing dampness syndrome when compared to healthy subjects. (2) There were 9 differential metabolites identified when the serum metabolites of the CHD patients with dampness syndrome were compared to those of CRF patients with dampness syndrome. There were 4 common metabolites found in the serums of both patient groups.

RESUMEN

BACKGROUND: Coronary artery ectasia (CAE) is not an uncommon clinical condition, which could be associated with adverse outcome. The exact pathophysiology of the disease is poorly understood and is commonly interpreted as a variant of atherosclerosis. In this study, we sought to undertake lipidomic profiling of a group of CAE patients in an attempt to achieve better understanding of its disturbed metabolism. METHODS: Untargeted lipid profiling and complementary modelling strategies were employed to compare serum samples from 16 patients with CAE (mean age 63.5±10.1years, 6 female) and 26 controls with normal smooth coronary arteries (mean age 59.2±6.6years and 7 female). Sample preparation, LC-MS analysis and metabolite identification were performed at the Swedish Metabolomics Centre, Umeå, Sweden. RESULTS: Phosphatidylcholine levels were significantly distorted in the CAE patients (p=0.001-0.04). Specifically, 16-carbon fatty acyl chain phosphatidylcholines (PC) were detected in lower levels. Similarly, 11 meioties of Sphyngomyelin (SM) species were detected at lower concentrations (p=0.000001-0.01) in the same group. However, only three metabolites were significantly higher in the pure CAE subgroup (6 patients) when compared with the 10 mixed CAE patients (two meioties of SM species and one of PC). Atherosclerosis risk factors were not different between groups. CONCLUSION: This is the first lipid profiling study reported in coronary artery ectasia. While the lower concentration and dysregulation of sphyngomyelin suggests an evidence for premature apoptosis, that of phosphatidylcholines suggests perturbed fatty acid elongation/desaturation, thus may be indicative of non-atherogenic process in CAE.

RESUMEN

BACKGROUND AND AIMS: Our study aims to evaluate the efficacy and safety of long-term treatment of statins for coronary heart disease (CHD). METHODS: Efficacy outcomes included changes in blood lipids, risk of CHD mortality and all-cause mortality. Safety outcomes were evaluated by the risk of adverse events (AE). Bayesian network meta-analysis was used to compare the direct and indirect effects between different statins. RESULTS: The systematic review showed that levels of blood lipids decreased during statin treatment. High dose of atorvastatin was the most obvious treatment for the reduction of blood lipids. Network meta-analysis showed that statins were significantly more effective than the control in reducing the risk of CHD mortality (Odds Ratio (OR) 0.69, 95% CI 0.61-0.77) and all-cause mortality (OR 0.84, 95% CI 0.80-0.87). In terms of reducing the risk of CHD morality, fluvastatin (77.3%), atorvastatin (72.3%) and lovastatin (68.4%) had higher cumulative probability than other statins, which were more effective treatments for the reduction of CHD morality. In terms of reducing all-cause mortality, atorvastatin (78.6%), fluvastatin (77.1%) and pitavastatin (74.1%) had higher cumulative probability than other statins, which were more effective treatment for reducing the all-cause mortality. Compared with placebo, statins increased the incidence risk of muscle disease (OR 1.05, 95% CI 1.00-1.10) and kidney disease (OR 1.11, 95% CI 1.05-1.72). CONCLUSIONS: Statins significantly reduced levels of blood lipids, with a high dose of atorvastatin being the most effective in blood-lipid level modification. Statins reduced the risk of CHD mortality and all-cause mortality, with atorvastatin and fluvastatin being the most effective in reducing the risk of CHD mortality and all-cause mortality. Statins increased the risk of muscle disease and kidney damage.

RESUMEN

Due to the high ambient temperature, sauna deaths show a few confounding particularities, such as an accelerated onset of the postmortem changes, that can make correct assessment of the manner of death difficult and severely constrain the accuracy of post- mortem interval estimates. This retrospective study, performed at the medicolegal institutes in Hesse, Germany, reviewed all autopsy reports from the years 1994-2014 for sauna-related deaths. 9 relevant cases were found involving one woman and eight men aged between 52 and 80 years (mean and median value: 67 years). Of the individuals who had died of a natural cause, four were found to have had coronary heart disease, which, in the setting of heart hypertrophy and exposure to high temperatures, ultimately led to cardiac failure. In three other cases, a non-natural cause of death had been diagnosed; however, all were attributable to accidents. In two of these, blood alcohol concentrations (BAC) of over two per mil were found. In our opinion, the manner of death should be classified as undetermined in sauna-related fatalities. Such cases require a court-ordered autopsy to reliably identify the actual cause of death.

RESUMEN

The long-chain polyunsaturated fatty acids are considered to be of major health importance, and recent studies indicate that their endogenous metabolism is influenced by B-vitamin status and smoking habits. We investigated the associations of circulating B-vitamins and smoking habits with serum polyunsaturated fatty acids among 1,366 patients who underwent coronary angiography due to suspected coronary heart disease at Haukeland University Hospital, Norway. Of these, 52% provided information on dietary habits by a food frequency questionnaire. Associations were assessed using partial correlation (Spearman's rho). In the total population, the concentrations of most circulating B-vitamins were positively associated with serum n-3 polyunsaturated fatty acids, but negatively with serum n-6 polyunsaturated fatty acids. However, the associations between B-vitamins and polyunsaturated fatty acids tended to be weaker in smokers. This could not be solely explained by differences in dietary intake. Furthermore, plasma cotinine, a marker of recent nicotine exposure, showed a negative relationship with serum n-3 polyunsaturated fatty acids, but a positive relationship with serum n-6 polyunsaturated fatty acids. In conclusion, circulating B-vitamins are, in contrast to plasma cotinine, generally positively associated with serum n-3 polyunsaturated fatty acids and negatively with serum n-6 polyunsaturated fatty acids in patients with suspected coronary heart disease. Further studies should investigate whether B-vitamin status and smoking habits may modify the clinical effects of polyunsaturated fatty acid intake.

RESUMEN

The article reports the results of clinical and physiological studies of 93 patients presenting with post-infarction cardiosclerosis and sings of cerebrovascular disease. The experience with the application of the combined rehabilitative treatment including therapeutic physical exercises is based on the results of the observation of two groups of the patients. Those of the study group performed special physical exercises designed to act on brain hemodynamics. The patients of the control group used traditional therapeutic exercises usually prescribed to those suffering from coronary artery disease. It was shown that the treatment including therapeutic physical exercises offered to the patients of the study group has an advantage of the significant positive impact on haemodynamics and functional activity of the brain; moreover, it reduces the severity of cardio-vascular cerebral symptoms and thereby contributes to complete rehabilitation of the patients with post-infarction cardiosclerosis.

RESUMEN

OBJECTIVES: The objective of this study is to develop an experimental model of hyperlipidemia and insulin resistance (IR), markers of coronary heart disease (CHD) using high fat and high sugar (HFHS) diet and to evaluate the efficacy of the model using atorvastatin, a known antihyperlipidemic drug, pioglitazone, a known insulin sensitizer, and Tinospora cordifolia (Tc), an antidiabetic plant. MATERIALS AND METHODS: Following Institutional Animal Ethics Committee permission, the study was conducted in male Wistar rats (200-270 g). The model was developed using a high fat (vanaspati ghee: coconut oil, 3:1) oral diet along with 25% fructose (high sugar) added in drinking water over a period of 6 weeks. Atorvastatin (2.1 mg/kg/day), pioglitazone (2.7 mg/kg/day) and Tc (200 mg/kg/day) were administered 3 weeks after initiation of HFHS diet and continued for another 3 weeks. Parameters assessed were weight, lipid profile, fasting blood glucose, insulin, and gastric emptying. Serum malondialdehyde (MDA) and catalase were assessed as markers of oxidative stress. RESULTS: Administration of HFHS diet demonstrated a significant increase in blood glucose, insulin, total and low density lipoprotein cholesterol and triglycerides with a decrease in high density lipoprotein cholesterol. Treatment with test drugs decreased blood sugar, insulin, lipid parameters, increased gastric emptying rate, decreased MDA levels, and catalase activity when compared to HFHS diet group, confirming the efficacy of the model. Atherogenic index of all the test drugs (0.48, 0.57, and 0.53) was significantly lower as compared to HFHS diet group (1.107). CONCLUSION: This study confirms the development of a diet based cost-effective and time efficient experimental model, which can be used to study two important markers of cardiovascular disease that is, hyperlipidemia and IR and to explore the efficacy of new molecules in CHD.

RESUMEN

Abnormal lipid composition and metabolism of plasma lipoproteins play a crucial role in the pathogenesis of coronary heart disease (CHD). A (1)H NMR-based lipidomic approach was used to investigate the correlation of coronary artery stenosis with the atherogenic (non-HDL) and atheroprotective (HDL) lipid profiles in 99 patients with CHD of various stages of disease and compared with 60 patients with normal coronary arteries (NCA), all documented in coronary angiography. The pattern recognition models created from lipid profiles predicted the presence of CHD with a sensitivity of 87% and a specificity of 88% in the HDL model and with 90% and 89% in the non-HDL model, respectively. Patients with mild, moderate, and severe coronary artery stenosis were progressively differentiated from those with NCA in the non-HDL model with a statistically significant separation of severe stage from both mild and moderate. In the HDL model, the progressive differentiation of the disease stages was statistically significant only between patients with mild and severe coronary artery stenosis. The lipid constituents of lipoproteins that mainly characterized the initial stages and then the progression of the disease were the high levels of saturated fatty acids in lipids in both HDL and non-HDL particles, the low levels of HDL-phosphatidylcholine, HDL-sphingomyelin, and omega-3 fatty acids and linoleic acid in lipids in non-HDL particles. The conventional lipid marker, total cholesterol, found in low levels in HDL and in high levels in non-HDL, also contributed to the onset of the disease but with a much lower coefficient of significance. (1)H NMR-based lipidomic analysis of atherogenic and atheroprotective lipoproteins could contribute to the early evaluation of the onset of coronary artery disease and possibly to the establishment of an appropriate therapeutic option.

RESUMEN

BACKGROUND: Acute Coronary Syndrome (ACS), is a serious threat to people's health, and life, and in recent years, the incidence has increased yearly. This study was to propose the hypothesis of "endogenous collateral wind" based on the patho-mechanism of thrombogenesis complicated by ruptured plaque on ACS, and the theory of traditional Chinese medicine. MATERIALS AND METHODS: Through successful coronary angiography (CAG), and intravascular ultrasound (IVUS), patients with coronary artery disease were made the differential diagnosis such as blood stasis, blood stasis due to phlegm obstruction, and endogenous collateral wind. The levels of plasma inflammatory marker were measured to study on the characteristics of "endogenous collateral wind". Luo heng dripping pills with promoting blood circulation to expel wind-evil, and remove wetness were made based on the hypothesis of "endogenous collateral wind" on ACS. Patients with unstable angina were randomly divided into 3, groups based on therapeutic methods: conventional therapy group, Luo Heng dripping pills group and Tongxinluo caps. Differences among groups were compared. RESULTS: There were great changes in number and degree of coronary arteriostenosis confirmed by CAG, the types of ACC/AHA lesion and Levin lesion confirmed by CAG, remodeling index, positive or negative remodeling percentage measured by IVUS, the plasma levels of plasma inflammatory marker measured by ELLSA in the patients with endogenous collateral wind, compared with patients with blood stasis and blood stasis due to phlegm obstruction. The total effective rate of improved angina in Luo Heng dripping pills group was significantly higher than those in other two groups. The levels of plasma inflammatory marker were significantly lower in Luo Heng dripping pills group. CONCLUSION: There were some pathological basis which were found about the hypothesis of "endogenous collateral wind" on acute coronary syndrome. It provided evidences for patients with coronary artery disease treated by medicines with expelling evil-wind, and removing wetness.

RESUMEN

PURPOSE OF REVIEW: This review summarizes current epidemiologic evidence regarding the associations of dietary fat and other nutrients with risk of stroke. RECENT FINDINGS: Recent epidemiologic studies show no association of total fat intake or absolute intakes of saturated, monounsaturated, or polyunsaturated fat with risk of stroke. Data on long-chain omega-3 polyunsaturated fatty acids in relation to stroke risk are inconclusive but may favor fewer strokes in women. Insufficient evidence exists for trans fatty acids, other fatty acids, and dietary cholesterol intake. Present evidence indicates that high dietary magnesium and potassium intakes may lower the risk of stroke, whereas a high sodium (salt) intake and a low dietary vitamin D intake likely increase stroke risk. Calcium does not prevent stroke in populations with moderate-to-high calcium intakes but might play a role in populations with low calcium intakes. Supplementation with single vitamins likely has no protective effect on stroke in well nourished populations. SUMMARY: Available epidemiologic evidence indicates that diets high in magnesium and potassium may play a role in the prevention of stroke, whereas a high sodium intake is a risk factor. It remains unclear whether specific fatty acids, dietary cholesterol, and combinations of vitamins affect the risk of stroke.

RESUMEN

OBJECTIVE: To study the effects of Naoxintong Capsule (NC) on the inflammation and long-term prognosis in the borderline lesion coronary heart disease patients. METHODS: A total of 240 coronary heart disease patients with angina symptoms and accompanied with borderline lesion coronary heart disease (with the diameter stenosis in critical 50% -70%) by means of coronary angiography or multislice computed tomography coronary angiography were recruited. These patients were randomly assigned to the conventional treatment group (including nitrate, beta blockers, anti-platelet, anticoagulation, angiotensin converting enzyme inhibitors, and so on) and the NC treatment group (treated the same way as those for the conventional treatment group and NC). All patients were treated for 12 months. The occurrence of cardiovascular events was observed after treatment. The inflammatory factors in serum [interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha), and high sensitive C reaction protein (hs-CRP)], matrix metalloproteinases-9 (MMP-9), blood lipids and blood sugar, liver and kidney functions were measured before and after treatment. RESULTS: After 12 months of treatment, the incidence of angina pectoris patients (6.67% vs 15.83%, P < 0.05) and hospitalization due to acute coronary syndrome (ACS) attacks (4.17% vs 10.83%) was significantly lower in the NC treatment group than in the conventional treatment group. There was no statistical difference in the serum levels of IL-6, TNF-alpha, hs-CRP, and MMP-9 between the two groups before treatment (P > 0.05). After 12 months of treatment, serum levels of IL-6, TNF-alpha, hs-CRP, and MMP-9 were significantly lower when compared with before treatment in the same group (P < 0.05). Besides, the serum levels of IL-6, TNF-alpha, hs-CRP, and MMP-9 were significantly lower in the NC group than in the conventional treatment group (P < 0.05). By means of Logistic regression analysis we found that the post-treatment MMP-9 level and IL-6 level were independent risk factors influencing the recurrence of angina pectoris. CONCLUSIONS: NC could alleviate the inflammation. Long-term administration of NC could reduce the recurrence of angina pectoris and decrease the incidence of ACS attack in borderline lesion coronary heart disease patients. The post-treatment MMP-9 level and IL-6 level were independent risk factors influencing the recurrence of angina pectoris.
