RESUMO
Objective To investigate effect of wenxin granule combined with metoprolol on blood rheology and clinlical efficacy of patients with premature hypertension heart disease.Methods 71 cases of hypertensive patients with hypertension and ventricular premature beat were selected, and randomly divided into a control group of 34 cases and observation group of 37 cases.The control group received metoprolol, the observation group on the base of the control group with wenxin granule.Blood rheology level, clinical efficacy and adverse reaction rate were compared before and after the treatment.Results Before treatment, high blood viscosity, whole blood low shear viscosity, plasma viscosity and fibrinogen levels had no significant difference in two groups of patients.After treatment, these indexs reduced compared with the same group pre-treatment(P<0.05);compared with the control group, the observation group had lower blood rheology(P<0.05), the total effective rate was higher(χ2 =8.60,P<0.05), and the incidence rate of adverse reactions was no difference.Conclusion Wenxin Granule combined with metoprolol in treatment of hypertension and ventricular premature beat patients, can improve effectively blood rheology of patients, and has low adverse reactions.
RESUMO
Objective The predictive value of the metabolic syndrome (MetS) for mortality from all-cause and cardiovascular disease (CVD) in the Chinese population is unclear. The aim of this present study was to compare MetS with its individual components as predictors of mortality in Chinese elderly adults. Methods A cohort of 1,535 subjects (994 men and 541 women) aged 50 years or older was selected from employees of a machinery factory in 1994 and followed until 2009. Cox models were used to estimate the hazard ratios (HRs) predicted by MetS according to the harmonized definition and by its individual components. Results The baseline prevalence of MetS was 28.0% in men and 48.4% in women. During a median follow-up of 15 years, 414 deaths occurred, of these, 153 participants died from CVD. Adjusted for age and gender, the HRs of mortality from all-cause and CVD in participants with MetS were 1.47 (95% confidence interval (CI): components. On evaluating the MetS components individually, we found that, independent of MetS, only hypertension and impaired glucose predicted higher mortality. Conclusions The number of positive MetS components seems no more informative than classifying (dichotomous) MetS for CVD risks assessment in this Chinese cohort.
RESUMO
In line with the new WHO definition for health and reference of comprehensive health assessments of elderly overseas, the paper screened and set the weight for comprehensive health assessment indicators for military officers, establishing a general health assessment model as a result 402 military officers were subject to Comprehensive Health Assessments, and the outcomes were compared with subjective assessment of experts. The results of both methods are highly coincidental. It proves Comprehensive Health Assessment as a scientific quantitative health assessment method, with promising perspectives in health management in the future.
RESUMO
Prevalence of dislipidemia is increasing rapidly in China and there has been a growing interest in Chinese herbal medicine for the treatment of hyperlipidemia both inside and outside China. In this article, lipids regulating effects of 9 herbs or their extracts and 5 herbal formulae which have been published in English-language literature are reviewed. Although evidence from animals and humans consistently supports the therapeutic activities of these Chinese herbal medicines, few multi-center large-scale clinical trials have been conducted to confirm the efficacy and evaluate their safety.
RESUMO
Objective To evaluate the effectiveness and feasibility of web-based lifestyle Or behavior intervention on Chinese urban adults.Methods Six hundred and eighty-one adult subjects were rand omly assigned to the intervention group (n=341) or the control group (n=340).The intervention group was encouraged to visit a specified interactive web site at 1east once a month to submit self-report health diaries.and provided with individualized health promotion instructions and tailored counseling at the chat room or through email.The control group received routine medical services.The primary outcomes were changes in cigarette smoking,alcohol consumption,fruit or vegetable intake,and physical exercise duration at 6 month from baseline.Intention-to-treat method was used for data analysis.Results At 6 month,smoking cessation rate was 23.6% in intervention group and 4.6% in control group (X2=22.4,P<0.05),and daily alcohol consumption decreased by 28.6 g in intervention group compared to 6.1 g in control group (t=14.9.P<0.05).There Was no significant change in physical exercise duration for those with sub-optimal physical activities between the two groups.In contrast to the control group.mean systolic blood pressure,fasting blood glucose,and body mass index of the hypertensive,diabetic,or overweight/obese subjects in the intervention group showed statistically significant decrease.There was no significant change in serum cholesterol level for the participants with hypercholestemlemia in both groups.The attrition rate was 6.7% in the intervention group.Conclusion Web-based health management services may be helpful in promoting healthy lifestyle and behavior and enhancing the care of chronic conditions including hypertension,diabetes,overweight and obese.
RESUMO
Objectives:To report the clinical experience of combined interventional procedures in the treatment of elderly patients with coexisting two or more cardiovascular diseases in our medical center, and to assess the feasibility, safety and therapeutic efficacy of this management strategy. Methods : Patients were selected to the study if: 1) age ＞65 years; 2) with coexistence of two or more cardiovascular diseases which are indications for interventional therapy; 3) patients' general condition and organ functions allow the performance of combined multiple procedures; 4) the predicted procedure time is within 150 min; 5) the predicted contrast medium dosage is within 300 ml. The criteria we analyzed included procedural type, rocedural time, fluoroscopy time, dosage of contrast medium, success rates of the procedures, complications and in-hospital mortality. All patients were followed up for 30.4 ± 9.3 months,to determine the all-cause mortality, recurrence rates and adverse cardiac events. Results : From January 2000 to December 2004,combined interventional procedures were performed on 136 patients, with 2 procedures on 134 patients and 3 procedures on 2 patients.The mean procedure time was 115.4±11.6 min, the mean fluoroscopy time was 35.7±9.3 min, and the mean dosage of contrast medium used was 183.6±19.4 ml. Procedural success rate was 100%, no procedure related death or major complications occurred.Conclusion: Performed by a competent team, combined interventional procedures in elderly patients with multiple cardiovascular diseases were feasible and relatively safe.
RESUMO
Objective To investigate the prevalence of sleep-disordered breathing in elderly patients with permanent cardiac pacemaker implantation due to bradyarrhythmias, and the relationship between pacing mode and patients' sleep apnea-hypopnea index.Methods Forty-four elderly patients (＞60 years) with cardiac pacemaker and their 44 controls matched for gender, age, body mass index and cardiovascular morbidity were studied using polysomnography or portable sleep monitoring device. Results Prevalence of sleep-disordered breathing (apnea-hypopnea index ≥5/h) was 44.7% and the mean apnea-hypopnea index was 8.2 ±4.1/h in the cardiac pacemaker group, which were significantly higher than those in control subjects (25% and 4.6±2.4/h, respectively, P＜0.01 and P＜0.05). The mean apnea-hypopnea index of patients with DDD or AAI pacemaker was significantly lower than that of patients with VVI pacemaker. Conclusions Sleep-disordered breathing was more common in patients who had their cardiac pacemaker implanted due to bradyarrhythmias than in their matched controls. Compared with VVI pacing, DDD or AAI pacing may be more beneficial to patients with bradyarrhythmias and sleep-disordered breathing.
RESUMO
Tetramethylpyrazine (TMP) is a herb used widely in Traditional Chinese Medicine (TCM) as an antianginal drug. The exact mechanism whereby TMP treat ischemic heart disease is still not fully understood. The purpose of this study is to examine the anti-inflammatory effect of TMP in patients with acute coronary syndromes (ACS). Methods Thirty-two patients with acute myocardial infarction or unstable angina were randomly assigned to TMP group or control group. All patients received the same standard treatment. Patients in TMP group received TMP 3mg/kg every 12 hours for 5 days. Plasma concentrations of high-sensitivity Creactive protein (CRP), serum amyloid A (SAA) and plasminogen activator inhibitor-1 (PAI-1) were measured at baseline and after 5 days of therapy. Results Both CRP and SAA concentrations increased significantly in control group (P＜0.05) whilst in TMP group, only SAA had a significant increase (P＜0.05); the absolute increase of CRP, SAA, and PAI-1 were significantly less in TMP group than in control group (P＜0.05). Conclusion TMP has an anti-inflammatory and profibrinolytic effect in patients with ACS. These effects may contribute to the clinical benefits of TMP in ischemic heart disease.
RESUMO
To investigate whether the calcium channel blocker amlodipine could inhibit macrophage matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) expression and secretion. Methods Peritoneal macrophages were isolated from BALB/C mice and incubated with low (5μg/L), middle (15μg/L) and high (305μg/L) concentrations of amlodipine, or in the medium alone (controls) for 24 hours, and the expression and secretion of MMP-2 and MM-9 of the cells were analyzed by RT-PCR and gelatin zymography. Results Compared with controls, amlodipine at low concentration had no significant effects on the expression and secretion of either MMP-2 and MMP-9 (P＞0.05);at middle concentrationit it could inhibited MMP-2 and MMP-9 expressions completely and significantly reduced the secretion of MMP-9 (P＜0.05); but it had no effect on the secretion of MMP-2. At high concentration it also inhibited MMP-2 and MMP-9 expression completely. Conclusion Amlodipine at 15 ìg/L inhibited the expression of MMP-2 and MMP-9 and reduced the secretion of MMP-9, suggesting that amlodipine may stabilize atherosclerotic plaque.
