    Full Text Available Aim. To evaluate antianginal and antiischemic efficiency of nebivolol in patients with stable angina pectoris.Material and methods. 100 patients with ischemic heart disease showing stable exertional angina pectoris and having no contraindications to beta-blockers were studied. After 5-7 days of control period 50 randomly selected patients began to take nebivolol in initial dose of 5mg once daily and 50 patients started to take metoprolol in initial dose of 50 mg twice daily. Duration of treatment was 8 weeks. Efficiency of treatment was assessed according to the results of control treadmill assessment and control daily ECG monitoring.Results. 56-day therapy with nebivolol at a dose of 7,5 mg per day results in increase in duration of treadmill test before angina or ST depression (p<0.05. Antianginal and antiischemic effect of nebivolol 7.5 mg once daily is rather similar with that of metoprolol in average daily dose of 175 mg. Nebivolol compared to metoprolol significantly (p<0.05 more effectively reduces the number of silent myocardial ischemia.Conclusion. Nebivolol is an efficient antianginal and antiischemic drug for patients with stable exertional angina pectoris.

  2. Comparative effects of propranolol and verapamil alone and in combination on left ventricular function and volumes in patients with chronic exertional angina: a double-blind, placebo-controlled, randomized, crossover study with radionuclide ventriculography

    International Nuclear Information System (INIS)

    With the use of equilibrium radionuclide ventriculography the effects on left ventricular (LV) function of 160 mg oral propranolol daily and 360 mg verapamil daily alone and in combination were compared in 18 patients with chronic exertional angina. A randomized, double-blind, placebo-controlled, crossover protocol was used. The reduction in exercise rate-pressure product induced by the combination (118 +/- 28 mm Hg/min) was significantly greater than that by propranolol (135 +/- 27 mm Hg/min) or verapamil alone (163 +/- 28 mm Hg/min). In patients at rest, neither single nor combined therapy altered global or regional left ventricular ejection fractions (EFs). Verapamil, but not propranolol, increased cardiac volumes of resting subjects; used in combination, no further increase in LV volume occurred. With placebo, exercise global EF did not decrease from the level at rest and therefore no drug effect could be demonstrated for this parameter of LV function. By an evaluation of normalized regional EF measurements the combination was shown to reduce exercise-induced hypokinesis (placebo 52 +/- 20%, combination 61 +/- 23%. No significant improvement was noted with propranolol or verapamil alone; only the combination prevented a significant increase in end-systolic and end-diastolic volumes during exercise. Thus, propranolol and verapamil, used alone in moderate doses, exert no beneficial effect on exercise LV function as measured by EF and volume changes, and resting function deteriorates slightly with verapamil

  3. Angina and exertional myocardial ischemia in diabetic and nondiabetic patients: assessment by exercise thallium scintigraphy

    International Nuclear Information System (INIS)

    Patients with diabetes mellitus and coronary artery disease are thought to have painless myocardial ischemia more often than patients without diabetes. We studied 50 consecutive patients with diabetes and 50 consecutive patients without diabetes, all with ischemia, on exercise thallium scintigraphy to show the reliability of angina as a marker for exertional ischemia. The two groups had similar clinical characteristics, treadmill test results, and extent of infarction and ischemia, but only 7 patients with diabetes compared with 17 patients without diabetes had angina during exertional ischemia. In diabetic patients the extent of retinopathy, nephropathy, or peripheral neuropathy was similar in patients with and without angina. Angina is an unreliable index of myocardial ischemia in diabetic patients with coronary artery disease. Given the increased cardiac morbidity and mortality in such patients, periodic objective assessments of the extent of ischemia are warranted

    Percutaneous coronary intervention and anti-anginal medications have similar prognostic effectiveness in patients with chronic stable angina. The choice of optimal medical therapy for the management of chronic angina is of pivotal importance in patients with stable ischemic heart disease. The most commonly used anti-anginal agents have demonstrated equivalent efficacy in improving patient reported ischemic symptoms and quantitative exercise parameters. With regards to mortality, beta-blockers are beneficial only in the setting of depressed left ventricular systolic function after a recent myocardial infarction. Recent evidence suggests the lack of any benefit of beta-blockers in patients with preserved systolic function, even in the setting of prior myocardial infarction.Ranolazine is a non-haemodynamic anti-anginal agent. It is effective as adjunctive therapy in patients with chronic stable angina whose symptoms are un-adequately controlled by conventional treatment. The clinical development program of ranolazine has shown that the drug improves exercise performance, decreases angina and use of sublingual nitrates, compared to placebo. Ranolazine is well tolerated with neutral effect on haemodynamics. Besides its role in chronic stable angina, ranolazine has the potential for development in a number of other cardiovascular and non-cardiovascular conditions in the future.

    Full Text Available Chronic stable angina (CSA is a significant problem in the United States that can negatively impact patient quality of life (QoL. An accurate assessment of the severity of a patient’s angina, the impact on their functional status, and their risk of cardiovascular complications is key to successful treatment of CSA. Active communication between the patient and their healthcare provider is necessary to ensure that patients receive optimal therapy. Healthcare providers should be aware of atypical symptoms of CSA in their patients, as patients may continue to suffer from angina despite the availability of multiple therapies. Patient questionnaires and symptom checklists can help patients communicate proactively with their healthcare providers. This paper discusses the prevalence of CSA, its impact on QoL, and the tools that healthcare providers can use to assess the severity of their patients’ angina and the impact on QoL.

Patients with T2DM have more extensive CAD and present at a younger age; therefore, identification and management of chronic angina in these patients presents an opportunity to limit both cardiovascular symptoms and adverse outcomes. This article reviews the role of screening and treatment for chronic angina in patients with T2DM. There is a strong evidence base for modifying lifestyle as a way of reducing adverse cardiovascular outcomes in the diabetic population and this article reviews evidence of lifestyle modification as an important and necessary adjunct to pharmacologic intervention. Management of chronic stable angina is addressed by looking at treatments that reduce ischemic symptoms and those that reduce adverse cardiovascular outcomes. Trials specific to the diabetic population are limited, with information largely obtained from the diabetic subgroup analysis of large intervention trials. The growing diabetic population with increased propensity to cardiovascular disease mandates trials specifically in this patient population. Revascularization in patients with diabetes is associated with more complications than in the non-diabetic population. Recent trials specific to this population suggest surgical revascularization to be associated with better long-term outcomes and therefore, this article reviews the evidence for the optimal mode of revascularization in this population.

    Full Text Available Richard KonesThe Cardiometabolic Research Institute, Houston, Texas, USAAbstract: The objectives in treating angina are relief of pain and prevention of disease ­progression through risk reduction. Mechanisms, indications, clinical forms, doses, and side effects of the traditional antianginal agents – nitrates, ß-blockers, and calcium channel ­blockers – are reviewed. A number of patients have contraindications or remain unrelieved from anginal discomfort with these drugs. Among newer alternatives, ranolazine, recently approved in the United States, indirectly prevents the intracellular calcium overload involved in cardiac ischemia and is a welcome addition to available treatments. None, however, are disease-modifying agents. Two options for refractory angina, enhanced external counterpulsation and spinal cord stimulation (SCS, are presented in detail. They are both well-studied and are effective means of treating at least some patients with this perplexing form of angina. Traditional modifiable risk factors for coronary artery disease (CAD – smoking, hypertension, dyslipidemia, ­diabetes, and obesity – account for most of the population-attributable risk. Individual therapy of high-risk patients differs from population-wide efforts to prevent risk factors from appearing or reducing their severity, in order to lower the national burden of disease. Current American College of Cardiology/American Heart Association guidelines to lower risk in patients with chronic angina are reviewed. The Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation (COURAGE trial showed that in patients with stable angina, optimal medical therapy alone and percutaneous coronary intervention (PCI with medical therapy were equal in preventing myocardial infarction and death. The integration of COURAGE results into current practice is discussed. For patients who are unstable, with very high risk, with left main coronary artery lesions, in

    A growing number of patients with chronic artery disease suffer from angina, despite the optimal medical management (ie, β-blockers, calcium channel blockers, and long-acting nitrates) and revascularization. Currently, enhanced external counterpulsation (EECP) therapy has been verified as a noninvasive, safe therapy for refractory angina. The study was designed to evaluate the efficacy of EECP in patients with chronic refractory angina according to Canadian Cardiovascular Society (CCS) angina class.We identified systematic literature through MEDLINE, EMBASE, the Cochrane Clinical Trials Register Database, and the ClinicalTrials. gov Website from 1990 to 2015. Studies were considered eligible if they were prospective and reported data on CCS class before and after EECP treatment. Meta-analysis was performed to assess the efficacy of EECP therapy by at least 1 CCS angina class improvement, and proportion along with the 95% confidence interval (CI) was calculated. Statistical heterogeneity was calculated by I statistic and the Q statistic. Sensitivity analysis was addressed to test the influence of trials on the overall pooled results. Subgroup analysis was applied to explore potential reasons for heterogeneity.Eighteen studies were enrolled in our meta-analysis. Pooled analysis showed 85% of patients underwent EECP had a reduction by at least one CCS class (95%CI 0.81-0.88, I = 58.5%, P < 0.001). The proportion of patients enrolled at primarily different studies with chronic heart failure (CHF) improved by at least 1 CCS class was about 84% after EECP (95%CI 0.81-0.88, I = 32.7%, P = 0.1668). After 3 large studies were excluded, the pooled proportion was 82% (95%CI 0.79-0.86, I = 18%, P = 0.2528). Funnel plot indicated that some asymmetry while the Begg and Egger bias statistic showed no publication bias (P = 0.1495 and 0.2859, respectively).Our study confirmed that EECP provided an effective treatment for patients who were unresponsive to medical management and

    In order to study the efficacy and tolerance of isradipine, a new Ca++ antagonist for the treatment of stable chronic angina, a multicentric cooperative study was carried out in eight Latin American countries (Argentine, Chile, Colombia, Ecuador, Mexico, Peru, Uruguay and Venezuela), which included 169 patients (60% men and 40% women), average age 62.6 +/- 9.7. Patients with more than 4 biweekly anginal crisis were accepted, with one or more of the following inclusion criteria: coronariographic evidence of obstruction greater than 60% in one or more vessels, IAM history, positive scintigraphy and positive effort test. The trial was single-blind, with placebo during the admission phase (2 weeks) and active treatment for 12 weeks. isradipine was administered in increasing doses of 2.5, 5, and 7 mg thrice a day, according to the presence or absence of anginal crisis. It was observed that the average frequency of weekly pains decreased from 8.2 +/- 7 under placebo to 6.3 +/- 7.5 under isradipine at low doses, and to 2.0 +/- 2.0 (p less than 0.001) under maximum doses. TNT intake decreased parallel also in a significant way. At the end of the trial, 37% of patients had become asymptomatic, and angina had reduced to less than two crisis a week in 33%. A clear relation doses-effect was observed. There was no alteration in laboratory exams neither in ECG. Seven patients had complications derived from the evolutional course of disease (2 IAM, 5 unstable angina and one sudden death). Adverse events were relatively frequent and the majority derived from vasodilator effect (tibial oedema 37%, flushing 17%, headache 23%).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1829846

    Full Text Available Chronic exertional compartment syndrome (CECS is a relatively rare condition that affects young adult athletes and often causes them to present to the emergency department. If left untreated, those who continue to compete at high levels may experience debilitating leg pain. Physicians may have difficulty differentiating CECS from other syndromes of the lower leg such as medial tibial stress syndrome, stress fractures, and popliteal artery entrapment. The gold standard for diagnosing CECS is intramuscular compartment pressure monitoring before and/or after 10 minutes of exercise. Some patients may choose to stop participation in sports in order to relieve their pain, which otherwise does not respond well to nonoperative treatments. In patients who wish to continue to participate in sports and live an active life, fasciotomy provides relief in 80% or more. The typical athlete can return to training in about 8 weeks. This is a case of a high school soccer player who stopped competing due to chronic exertional compartment syndrome. She had a fascial hernia, resting intramuscular pressure of 30 mmHg, and postexercise intramuscular pressure of 99 mmHg. Following fasciotomy she experienced considerable life improvement and is once again training and playing soccer without symptoms.

    Full Text Available Background: Coronary artery disease (CAD is a major cause of death and disability in developed countries. Chronic stable angina is the initial manifestation of CAD in approximately 50% of the patients. Recent evidence suggests that vitamin D is crucial for cardiovascular health. The prevalence of vitamin D deficiency in our region is 83%. A low level of vitamin D is associated with chronic stable angina. Aim: This study was aimed at supporting or refuting this hypothesis in our population. Materials and Methods: The study was a prospective case-control study. We studied 100 cases of chronic stable angina and compared them with 100 matched controls. Vitamin D deficiency was defined as <20 ng/mL, vitamin D insufficiency as 20-30 ng/mL and normal vitamin D level as 31-150 ng/mL. Results: The prevalence of vitamin D deficiency among cases and controls was 75% and 10%, respectively. 75% of the cases were vitamin D-deficient (<20 ng/mL; 12% were vitamin D-insufficient (20-30 ng/mL, and 13% had normal vitamin D levels (31-150 ng/mL. None had a toxic level of vitamin D. Among the controls, 10% were vitamin D-deficient, 33% were vitamin D-insufficient, and 57% had normal vitamin D levels. The mean vitamin level among cases and controls was 15.53 ng/mL and 40.95 ng/mL, respectively, with the difference being statistically significant (P ≤ 0.0001. There was no statistically significant relation between the disease severities, i.e., on coronary angiography (CAG with vitamin D level. Among the cases, we found that an increasing age was inversely related to vitamin D levels (P = 0.027. Conclusion: Our study indicates a correlation between vitamin D deficiency and chronic stable angina. Low levels may be an independent, potentially modifiable cardiovascular risk factor.

    A patient with a sinus bradycardia and angina is described who was unable to increase his heart rate on vigorous exercise by more than a few beats. His severe angina was attributed to the bradycardia. Atrial pacing of his heart abolished his angina and increased his exercise tolerance. Circulatory changes at rest, on exertion, and with atrial pacing are described. The cause of angina in this patient is discussed.

    To conduct a systematic review of the evidence regarding the economic value of ranolazine relative to standard-of-care (SOC) for the treatment of symptomatic chronic stable angina (CSA). Electronic databases were searched using relevant keywords. The identified studies were independently reviewed by two investigators against pre-determined inclusion and exclusion criteria. Their data were extracted using a relevant form and consequently were synthesized. Studies were also evaluated using the Quality of Health Economic Studies scale. The main outcomes considered were the cost and effectiveness for each comparator and the incremental cost per quality-adjusted-life year (QALY) gained. Six studies were included in the review. Five of these assessed the cost-utility of ranolazine added to SOC, compared to SOC alone, using decision trees or Markov models whereas one was a retrospective cost evaluation study. The analysis was conducted from a payer perspective in five studies and from a societal perspective in one study with the time horizon varying between six months and a year. The incremental cost-effectiveness ratio (ICER), ranged from €4000 to €15,000 per QALY gained. Ranolazine appears to be dominant or cost-effective, mainly due to its ability to decrease angina-related hospitalizations and also due to a marginal improvement in quality of life. The acquisition cost of ranolazine was the variable with the greatest impact upon the ICER. The existing evidence, although limited, indicates that ranolazine may be a dominant or cost-effective therapy option, for the treatment of patients with symptomatic CSA. Further research is required to evaluate the cost-effectiveness of ranolazine. PMID:26994453

    Exertional dyspnoea is among the dominant symptoms in patients with chronic heart failure and progresses relentlessly as the disease advances, leading to reduced ability to function and engage in activities of daily living. Effective management of this disabling symptom awaits a better understanding of its underlying physiology.Cardiovascular factors are believed to play a major role in dyspnoea in heart failure patients. However, despite pharmacological interventions, such as vasodilators or inotropes that improve central haemodynamics, patients with heart failure still complain of exertional dyspnoea. Clearly, dyspnoea is not determined by cardiac factors alone, but likely depends on complex, integrated cardio-pulmonary interactions.A growing body of evidence suggests that excessively increased ventilatory demand and abnormal "restrictive" constraints on tidal volume expansion with development of critical mechanical limitation of ventilation, contribute to exertional dyspnoea in heart failure. This article will offer new insights into the pathophysiological mechanisms of exertional dyspnoea in patients with chronic heart failure by exploring the potential role of the various constituents of the physiological response to exercise and particularly the role of abnormal ventilatory and respiratory mechanics responses to exercise in the perception of dyspnoea in patients with heart failure.

    Full Text Available OBJECTIVES: To compare health-related quality of life (HRQoL between patients with stable angina and the general population in China and to examine factors associated with HRQoL among patients with stable angina. METHODS: A cross-sectional HRQoL survey of stable angina patients recruited from 4 hospitals (n = 411 and the general population recruited from 3 Physical Examination Centers (n = 549 was conducted from July to December, 2011 in two large cities, Tianjin and Chengdu. HRQoL was assessed using the EQ-5D, EQ-VAS, and SF-6D instruments. The health status specific to patients with stable angina was assessed using the Seattle Angina Questionnaire (SAQ. Information on socio-demographic, clinical, and lifestyle factors were also collected. Nested regressions were performed to explore how these factors were associated with HRQoL in patients with stable angina. RESULTS: Compared with the general population (44.2 ± 10 years, 49.9% females, stable angina patients (68.1 ± 12 years, 50.4% females had significantly lower HRQoL scores in EQ-5D utility index (0.75 ± 0.19 vs. 0.90 ± 0.20, p<0.05, SF-6D utility index (0.68 ± 0.12 vs. 0.85 ± 0.11, p<0.05, and EQ-VAS (71.2 ± 12.3 vs. 83.9 ± 10.9, p<0.05. The differences remained (-0.05 for EQ-5D, -9.27 for EQ-VAS and -0.13 for SF-6D after controlling for socio-economic characteristics. SAQ scores showed that stable angina patients experienced impaired disease-specific health status, especially in angina stability (40.5 ± 34.6. Nested regressions indicated stable angina-specific health status explained most of the variation in HRQoL, among which disease perception, physical limitation, and angina stability were the strongest predictors. More physical exercise and better sleep were positively related with HRQoL. CONCLUSIONS: Compared to the general population, stable angina patients were associated with lower HRQoL and lower health utility scores, which were largely impacted by clinical symptoms

In this study, 26 consecutive patients (age 61.3 ± 7.0 years, 13 females, angina duration 12.7 ± 6.0 years) were recruited. Social, mental, and physical aspects of QoL were determined by Nottingham Health Profile (NHP I), depression scale (CES-D), scoring of angina pectoris attacks and short-acting nitroglycerine intake, pain score on the Visual Analog Scale (VAS), perceived health percentage, Satisfaction With Life scale (SWLS), and one-aspect Linear Analog Self Assessment scale (LASA). QoL outcomes at baseline were compared with reference values from healthy subjects. Within-group changes and magnitude of changes (effect size, ES) were assessed after 3 months and 1 year of SCS. Results. Compared to healthy subjects, the patients had significantly worse scores at baseline on NHP, SWLS, and LASA. After 3 months of SCS, NHP I aspect pain (ES = 1.39), AP-score (ES = 0.85), perceived health percentage (ES =- 0.80), NTG-use (ES = 1.08) and VAS-score (ES = 1.13) were all significantly improved (p pain, energy, emotional reactions, social isolation, sleep, and physical mobility (p 0.80). Conclusion. QoL in patients with refractory angina pectoris is poor. Both pain and health aspects of QoL improved significantly after 3 months of SCS. Social, mental, and physical aspects of QoL were found improved after 1 year of SCS. PMID:22151060

    Chronic Fatigue Syndrome (CFS) is characterized in part by debilitating fatigue typically exacerbated by cognitive and/or physical exertion, referred to as post-exertional malaise (PEM). In a variety of populations, the cortisol awakening response (CAR) has stood out as a marker of endocrine dysregulation relevant to the experience of fatigue, and may therefore be particularly relevant in CFS. This is the first study to examine PEM and the CAR in a sample of individuals with CFS. The CAR has also been established as a stress-sensitive measure of HPA axis functioning. It follows that better management of stress could modulate the CAR, and in turn PEM. In this cross-sectional study, we hypothesized that greater Perceived Stress Management Skills (PSMS) would relate to lower reports of PEM, via the impact of PSMS on the CAR. A total of 117 adults (72% female) with a CFS diagnosis completed self-report measures of PSMS and PEM symptomatology and a two-day protocol of saliva collection. Cortisol values from awakening and 30 min post-awakening were used to compute the CAR. Regression analyses revealed that greater PSMS related to greater CAR and greater CAR related to less PEM severity. Bootstrapped analyses revealed an indirect effect of PSMS on PEM via the CAR, such that greater PSMS related to less PEM, via a greater CAR. Future research should examine these trends longitudinally and whether interventions directed at improving stress management skills are accompanied by improved cortisol regulation and less PEM in individuals with CFS.

    Oxidative stress has been claimed a place in pathophysiology of depression; however, the details of the neurobiology of this condition remains incompletely understood. Recently, treatments employing antioxidants have been thoroughly researched. Ferulic acid (FA) is a phenolic compound with antioxidant and antidepressant-like effects. Herein, we investigated the involvement of the antioxidant activity of chronic oral FA treatment in its antidepressant-like effect using the tail suspension test (TST) and the forced swimming test (FST) in mice. The modulation of antioxidant system in blood, hippocampus and cerebral cortex was assessed after stress induction through TST and FST. Our results show that FA at the dose of 1 mg/kg has antidepressant-like effect without affecting locomotor activity. The stress induced by despair tests was able to decrease significantly the activities of superoxide dismutase (SOD) in the blood, catalase (CAT) in the blood and cerebral cortex and glutathione peroxidase (GSH-Px) in the cerebral cortex. Thiobarbituric acid-reactive substances (TBA-RS) levels were increased significantly in the cerebral cortex. Furthermore, the results show that FA was capable to increase SOD, CAT and GSH-Px activities and decrease TBA-RS levels in the blood, hippocampus and cerebral cortex. These findings demonstrated that FA treatment in low doses is capable to exert antidepressant-like effect with the involvement of the antioxidant defense system modulation.

    To evaluate the perfusion decrease in donor myocardium by collateral circulation and its correlation with angina pectoris in patients with chronic total occlusion (CTO) using myocardial perfusion single-photon emission computed tomography (MPS). Thirty-six patients with single-vessel CTO without any other stenosis were included. All patients underwent MPS and coronary angiography (CAG) within 2 months. Total 72 donor arteries were evaluated for the grades of collaterals to the CTO artery using the Rentrop grading system on CAG. Perfusion defects and perfusion scores in donor and CTO territories were analyzed on MPS. Myocardial perfusion of donor and CTO territories were evaluated according to the presence of angina pectoris and the grades of collateral circulation. When the CTO territory was ischemic, symptomatic patients showed higher summed difference scores in the CTO territory compared to asymptomatic patients (3.5 ± 2.4 vs. 1.5 ± 0.8 for symptomatic and asymptomatic groups respectively; p = 0.034). However, when the CTO territory was nonischemic, symptomatic patients showed higher summed stress scores (SSS, 4.3 ± 2.9 vs. 1.6 ± 1.2; p = 0.032) and summed rest scores (SRS, 4.2 ± 2.5 vs. 1.5 ± 1.1; p = 0.003) in the donor territories. On the per-vessel analysis, perfusion defects in donor territories were more frequent (0 % vs. 53 % vs. 86 % for Rentrop 0, Rentrop 1–2 and Rentrop 3, respectively; p < 0.001) and showed higher SSS (0.0 ± 0.0, 1.3 ± 1.6 and 2.1 ± 1.1 for Rentrop 0, Rentrop 1–2 and Rentrop 3, respectively; p = 0.001) and SRS (0.0 ± 0.0, 1.0 ± 1.4 and 1.7 ± 1.2; p = 0.003) at higher Rentrop grades, but their patterns were variable. Angina pectoris was related to either ischemia of the myocardium beyond CTO or a perfusion decrease in the donor myocardium. The perfusion decrease in donor myocardium positively correlated with the collateral grades.

    Vasospastic angina is a diagnosis of exclusion that manifests with signs and symptoms, which overlap with obstructive coronary artery disease, most often ST-segment elevation myocardial infarction. The pharmacotherapy that is available to treat vasospastic angina can help ameliorate angina symptoms. However, the etiology of vasospastic angina is ill-defined, making targeted pharmacotherapy difficult. Most patients receive pharmacotherapy that includes calcium channel blockers and/or long-acting nitrates. This article reviews the efficacy and safety of the pharmacotherapy used to treat vasospastic angina. High-dose calcium channel blockers possess the most evidence, with respect to decreasing angina incidence, frequency, and duration. However, not all patients respond to calcium channel blockers. Nitrates and/or alpha1-adrenergic receptor antagonists can be used in patients who respond poorly to calcium channel blockers. Albeit, evidence for use of nitrates and alpha1-adrenergic receptor antagonists in vasospastic angina is not as robust as calcium channel blockers and can exacerbate adverse effects when added to calcium channel blocker therapy. Despite having a clear benefit in patients with obstructive coronary artery disease, the benefit of beta-adrenergic receptor antagonists, statins, and aspirin remains unclear. More data are needed to elucidate whether or not these agents are beneficial or harmful to patients being treated for vasospastic angina. Overall, the use of pharmacotherapy for the treatment of vasospastic angina should be guided by patient-specific factors, such as tolerability, adverse effects, drug-drug, and drug-disease interactions.

  14. The diagnostic value of MRI scans for the diagnosis of chronic exertional compartment syndrome of the lower leg

    International Nuclear Information System (INIS)

    Objective. A prospective descriptive study to determine the value of magnetic resonance imaging (MRI) as an aid in diagnosing (chronic) exertional compartment syndrome.Design and patients. MRI was performed in 21 patients (41 anterior compartments) with chronic compartment syndrome at rest and following physical exercise. Median (T2-weighted) signal intensity on the MRI scan was determined in the anterior and the (superficial) posterior compartment of the lower leg before and after exercise. Postexercise increases in the signal intensity in these two compartments were compared. After fasciotomy, a second MRI scan was performed in 13 patients (25 anterior compartments) on the basis of the same protocol. MR studies were performed in 12 normal controls (24 anterior muscle compartments) on the basis of the same protocol.Results. T2-weighted signal intensity increased by 27.5% (range 13.6-38.6%) following exercise in the anterior compartment of patients with a chronic compartment syndrome. In the posterior compartment this increase amounted to 4.25% (range 0-10.2%). Following fasciotomy, the increase in the anterior compartment was 4.1% (range 1.0-5.2%), while the increase in the posterior compartment amounted to 5.6% (range 0-11.0%), In normal controls, the increase in the anterior compartment was 7.6% (range 0-9.1%), while in the posterior compartment it was 4.0% (range 0-7.2%).Conclusions. In patients with a chronic compartment syndrome, the affected (anterior) compartment shows a statistically significant increase in (T2-weighted) signal intensity during exercise compared with both the (superficial) posterior compartment and the anterior compartment of normal controls. This effect disappeared after fasciotomy. In view of the substantial increase in T2-weighted signal intensity, MRI can be used in diagnosing chronic compartment syndrome. (orig.)

    Injury of the diaphragm may have clinical relevance having been reported in cases of sudden infant death syndrome or fatal asthma. However, examination of diaphragm injury after acute inspiratory loading has not been reported. The purpose of this study was to determine whether an acute inspiratory overload induces injury of the human diaphragm and to determine if diaphragm from chronic obstructive pulmonary disease (COPD) is more susceptible to injury. Eighteen patients with COPD and 11 control patients with normal pulmonary function (62 +/- 10 yr) undergoing thoracotomy or laparotomy were studied. A threshold inspiratory loading test was performed prior to surgery in a subset of seven patients with COPD and five control patients. Samples of the costal diaphragm were obtained during surgery and processed for electron microscopy analysis. Signs of sarcomere disruption were found in all diaphragm samples. The range of values of sarcomere disruption was wide (density: 2-45 abnormal areas/100 microm(2); area fractions: 1.3-17.3%), significantly higher in diaphragm from patients with COPD (p < 0.05) and with the greatest injury after inspiratory loading. We conclude that sarcomere disruption is common in the human diaphragm, is more evident in patients with COPD, and is higher after inspiratory loading, especially in the diaphragm of those with COPD.

    Full Text Available Richard KonesThe Cardiometabolic Research Institute, Houston, Texas 77054 USAAbstract: The potential importance of both prevention and personal responsibility in ­controlling heart disease, the leading cause of death in the USA and elsewhere, has attracted renewed ­attention. Coronary artery disease is preventable, using relatively simple and inexpensive lifestyle changes. The inexorable rise in the prevalence of obesity, diabetes, dyslipidemia, and ­hypertension, often in the risk cluster known as the metabolic syndrome, drives the ­ever-increasing incidence of heart disease. Population-wide improvements in personal health habits appear to be a fundamental, evidence based public health measure, yet numerous barriers prevent implementation. A common symptom in patients with coronary artery disease, classical angina refers to the typical chest pressure or discomfort that results when myocardial oxygen demand rises and coronary blood flow is reduced by fixed, atherosclerotic, obstructive lesions. Different forms of angina and diagnosis, with a short description of the significance of pain and silent ischemia, are discussed in this review. The well accepted concept of myocardial oxygen imbalance in the genesis of angina is presented with new data about clinical pathology of stable angina and acute coronary syndromes. The roles of stress electrocardiography and stress myocardial perfusion scintigraphic imaging are reviewed, along with the information these tests provide about risk and prognosis. Finally, the current status of gender disparities in heart disease is summarized. Enhanced risk stratification and identification of patients in whom procedures will meaningfully change management is an ongoing quest. Current guidelines emphasize efficient triage of patients with suspected coronary artery disease. Many experts believe the predictive value of current decision protocols for coronary artery disease still needs improvement in order to

    Refractory angina refers to a group of patients with stable coronary atherosclerotic disease and angina symptoms, unresponsive to traditional medical management, while considered to be suboptimal candidates for revascularization procedures. Up to 15% of angina patients are considered to have refractory angina and, taking into account the aging population and the improvements in the treatment of stable coronary artery disease, the incidence of this entity is expected to increase. This review describes traditional and novel pharmacotherapies for symptoms relief and for long-term management of refractory angina. Mechanisms of action and relevant clinical trials are discussed and current recommendations from major European and US cardiovascular societies are reported.

  20. Comparison of antianginal efficacy of nifedipine and isosorbide dinitrate in chronic stable angina: a long-term, randomized, double-blind, crossover study

    International Nuclear Information System (INIS)

    Using a double-blind, crossover design, the comparative efficacy and safety of nifedipine and isosorbide dinitrate in the treatment of stable angina were studied in 34 patients. The study included a 2-week placebo washout period and two 6-week periods during which patients were randomized to either nifedipine or isosorbide dinitrate. The doses were titrated for each patient, and mean doses of the 2 drugs were comparable. A time-limited thallium treadmill test was performed at the end of each phase. Ischemic zone count rates were normalized to those of the nonischemic zone, and the change in this ratio with redistribution was calculated as reversible thallium defect. Two patients were discontinued from the study within 1 week after initiation of isosorbide dinitrate because of severe, intolerable headache. Two patients were withdrawn while receiving nifedipine: one had new congestive heart failure and the other had increasing angina. Of the remaining 30 patients who tolerated both drugs for at least 1 week, 4 patients from the isosorbide dinitrate group were either prematurely crossed over or discontinued from the study because of headache. One patient suffered headache from both drugs and was discontinued from the study. In the 30 patients, only nifedipine significantly reduced resting arterial pressure compared with baseline. Further, only nifedipine therapy resulted in significant decreases in the rate-pressure product and systolic pressure at a given workload. However, significant decreases in angina frequency, nitroglycerin consumption and exercise-induced maximum ST-segment depression and reversible thallium perfusion defect were produced by both nifedipine and isosorbide dinitrate

    Full Text Available Background and Objectives: The treatment of hypertension and its complications are a worldwide problem. In our country nearly 25 % of the population over 15 years old is hypertensive, and this figure nearly doubles in those over 60. This research aims to compare two treatment strategies for controlling hypertension in outpatients with chronic coronary ischemic syndrome. Method: A total of 150 patients was included, 73 were randomized to receive calcium antagonist and non-calcium antagonist respectively, as 4 patients were subsequently excluded. Each was asked to sign consent, underwent clinical examination and a 12-lead, conventional electrocardiogram. Blood pressure and episodes of angina were evaluated at 6 months and one year. All variables were entered into a database and statistical analysis was performed using Student's t and Chi square. Results: The mean age was 61,5 years. Women and white skin color were predominant. At 12 months of treatment, blood pressure normalized in more than 80 % of patients without significant differences between the two treatment strategies. Over 75 % of patients in both groups controlled the angina episodes and more than 85 % said the quality of life was good. Conclusions: Control of blood pressure and angina was achieved and there were no significant differences between the two treatment strategies.

    Background Green tea intake has been shown to improve endurance capacity in animal studies, but whether it has a similar effect on humans remains unclear. A randomized, double-blinded, parallel-controlled study was conducted to evaluate the short-term effect of STA-2, a pharmaceutical preparation of green tea polyphenols, in patients with effort-induced angina and documented positive exercise tolerance test. Methods A total of 79 patients recruited from three medical centers were randomly assigned to receive 2 STA-2 250 mg capsules, each containing 100 mg green tea polyphenols, three times daily, or placebo for six weeks after two consecutive symptom-limited treadmill exercise tests to ascertain the reproducibility of exercise tolerance. Results There was no difference in total exercise tolerance time from baseline to Week 6 between two groups (p = 0.639). There were also no observed improvements in subgroup analyses stratified by age, gender, and BMI categories. However, a significant reduction in low-density lipoprotein levels was shown in patients in the STA-2 group (-8.99 ± 19.18 mg/dL) versus the placebo group (0.57 ± 19.77 mg/dL), p = 0.037, with greater benefits in patients not taking antihyperlipidemic drugs (STA-2: -9.10 ± 19.96 mg/dL vs. placebo: 4.42 ± 15.08 mg/dL, p = 0.037). Conclusions STA-2 treatment for 6 weeks did not increase exercise time as measured on a treadmill. However, this study also indicated that STA-2 treatment could have potential beneficial effects on LDL-cholesterol concentrations. PMID:27471357

    AIM: To evaluate the therapeutic effect of Chunggan extract (CGX), a modified traditional Chinese hepatotherapeutic herbal, on the dimethylnitrosamine (DMN)-induced chronic liver injury model in rats.METHODS: Liver injuries were induced in Wistar rats by injection of DMN (ip, 10 mg/mL per kg) for 3 consecutive days per week for 4 wk. The rats were administered with CGX (po, 100 or 200 mg/kg per day) or distilled water as a control daily for 4 wk starting from the 15th d of the DMN treatment. Biochemical parameters (serum albumin, bilirubin, ALP, AST and ALT), lipid peroxides,hydroxyproline, as well as histological changes in liver tissues were analyzed. In addition, gene expression of TNF-α, TGF-β, TIMP-1, TIMP-2, PDGF-β, and MMP-2, all of which are known to be associated with liver fibrosis,were analyzed using real-time PCR.RESULTS: CGX administration restored the spleen weight to normal after having been increased by DMN treatment.Biochemical analysis of the serum demonstrated that CGX significantly decreased the serum level of ALP (P< 0.05), ALT (P < 0.01), and AST (P < 0.01) that had been elevated by DMN treatment. CGX administration moderately lowered lipid peroxide production and markedly lowered hydroxyproline generation caused by DMN treatment in accordance with histopathological examination. DMN treatment induced a highly upregulated expression of TNF-α, TGF-β, TIMP-1, TIMP-2,PDGF-β, and MMP-2. Of these, the gene expression encoding PDGF-β and MMP-2 was still further enhanced 2 wk after secession of the 4-wk DMN treatment, and was remarkably ameliorated by CGX administration.CONCLUSION: CGX exhibits hepatotherapeutic properties against chronic hepatocellular destruction and consequential liver fibrosis.

    Purpose To collect diffusion tensor imaging (DTI) at multiple diffusion times Td in skeletal muscle in normal subjects and chronic exertional compartment syndrome (CECS) patients and analyze the data with the random permeable barrier model (RPBM) for biophysical specificity. Materials and Methods Using an IRB-approved HIPAA-compliant protocol, seven patients with clinical suspicion of CECS and eight healthy volunteers underwent DTI of the calf muscle in a Siemens MAGNETOM Verio 3-T scanner at rest and after treadmill exertion at 4 different diffusion times. Radial diffusion values λrad were computed for each of 7 different muscle compartments and analyzed with RPBM to produce estimates of free diffusivity D0, fiber diameter a, and permeability κ. Fiber diameter estimates were compared with measurements from literature autopsy reference for several compartments. Response factors (post/pre-exercise ratios) were computed and compared between normal controls and CECS patients using a mixed-model two-way analysis of variance. Results All subjects and muscle compartments showed nearly time-independent diffusion along and strongly time-dependent diffusion transverse to the muscle fibers. RPBM estimates of fiber diameter correlated well with corresponding autopsy reference. D0 showed significant (pmeasurements combined with appropriate tissue modeling can provide enhanced microstructural specificity for in vivo tissue characterization. In CECS patients, our results suggest that high-pressure interfiber edema elevates free diffusion and restricts exercise-induced fiber dilation. Such specificity may be useful in differentiating CECS from other disorders or in predicting its response to either physical therapy or fasciotomy. PMID:24610770

    Full Text Available Abstract Background Neuropathic pain is detrimental to human health; however, its pathogenesis still remains largely unknown. Overexpression of pain-associated genes and increased nociceptive somato-sensitivity are well observed in neuropathic pain. The importance of epigenetic mechanisms in regulating the expression of pro- or anti-nociceptive genes has been revealed by studies recently, and we hypothesize that the transcriptional coactivator and the histone acetyltransferase E1A binding protein p300 (p300, as a part of the epigenetic mechanisms of gene regulation, may be involved in the pathogenesis of neuropathic pain induced by chronic constriction injury (CCI. To test this hypothesis, two different approaches were used in this study: (I down-regulating p300 with specific small hairpin RNA (shRNA and (II chemical inhibition of p300 acetyltransferase activity by a small molecule inhibitor, C646. Results Using the CCI rat model, we found that the p300 expression was increased in the lumbar spinal cord on day 14 after CCI. The treatment with intrathecal p300 shRNA reversed CCI-induced mechanical allodynia and thermal hyperalgesia, and suppressed the expression of cyclooxygenase-2 (COX-2, a neuropathic pain-associated factor. Furthermore, C646, an inhibitor of p300 acetyltransferase, also attenuated mechanical allodynia and thermal hyperalgesia, accompanied by a suppressed COX-2 expression, in the spinal cord. Conclusions The results suggest that, through its acetyltransferase activity in the spinal cord after CCI, p300 epigenetically plays an important role in neuropathic pain. Inhibiting p300, using interfering RNA or C646, may be a promising approach to the development of new neuropathic pain therapies.

  14. Myocardial bridge: The cause of angina in a young man

    International Nuclear Information System (INIS)

    Myocardial bridging is basically the systolic narrowing of epicardial coronary arteries, secondary to their tunneled course in myocardium. Though it is a benign condition it can have the symptoms like acute coronary syndrome, arrhythmias and sudden cardiac death. We report a 32-year-old male, who presented with typical exertional angina, had positive exercise treadmill and thallium-201 test. Coronary angiography revealed myocardial bridge of distal left anterior descending coronary artery. He was put on β-blockers and was doing well at 8 years of follow-up

    Full Text Available J Nicolás Codolosa,1 Subroto Acharjee,1 Vincent M Figueredo1,2 1Einstein Center for Heart and Vascular Health, Einstein Medical Center, 2Jefferson Medical College, Philadelphia, PA, USA Abstract: Mortality rates attributable to coronary heart disease have declined in recent years, possibly related to changes in clinical presentation patterns and use of proven secondary prevention strategies. Chronic stable angina (CSA remains prevalent, and the goal of treatment is control of symptoms and reduction in cardiovascular events. Ranolazine is a selective inhibitor of the late sodium current in myocytes with anti-ischemic and metabolic properties. It was approved by the US Food and Drug Administration in 2006 for use in patients with CSA. Multiple, randomized, placebo-controlled trials have shown that ranolazine improves functional capacity and decreases anginal episodes in CSA patients, despite a lack of a significant hemodynamic effect. Ranolazine did not improve cardiovascular mortality or affect incidence of myocardial infarction in the MERLIN (Metabolic Efficiency with Ranolazine for Less Ischemia in Non-ST-Elevation Acute Coronary Syndrome-TIMI (Thrombolysis In Myocardial Infarction 36 trial, but significantly decreased the incidence of recurrent angina. More recently, ranolazine has been shown to have beneficial and potent antiarrhythmic effects, both on supraventricular and ventricular tachyarrhythmias, largely due to its inhibition of the late sodium current. Randomized controlled trials testing these effects are underway. Lastly, ranolazine appears to be cost-effective due to its ability to decrease angina-related hospitalizations and improve quality of life.

  16. Myocardial ischemia and angina pectoris

    International Nuclear Information System (INIS)

    Ambulatory monitoring of ST segment changes was performed in 60 patients presenting with angina, positive ECG stress tests and coronary artery disease, 85% of ischemic ECG events were asymptomatic, 37% occurred with no increase in heart rate and 15% of episodes either lasted 20 minutes or more or fluctuated in severity. A controlled pilot study in ten patients showed depression. Radionuclide studies in 50 patients with angina and coronary artery disease have shown that stress (i.e., atrial pacing) produced different patterns of disturbed regional myocardial perfusion related to the patient's exercise capacity and eventually leading to a decrease in regional myocardial perfusion during the ischemic episode. ST segment depression appeared only after the decrease in regional myocardial perfusion. These findings combined with past research suggest that patients with angina and coronary artery disease can suffer frequent asymptomatic disturbances of the regional myocardial perfusion. The frequency of these episodes and the time course for the recovery of the metabolic consequences mean that segments of ventricular myocardium may be constantly abnormal. The relative importance of changes in coronary tone and malfunction of platelets in the diseased coronary tree needs to be examined in clinical research. Pilot studies of antiplatelet agents have shown a significant beneficial effect on episodes of ischemia occurring at night and those occurring without any increase in heart rate. The techniques and observations in these patients with coronary artery disease all suggest that acute transient regional myocardial ischemia is caused by a variety of mechnisms. Further research using objective methods is required to discover the causes of ischemia and to rationalize treatment. (orig./MG)

  17. Chronic exertional compartment syndrome of the lower extremities: improved screening using a novel dual birdcage coil and in-scanner exercise protocol

    International Nuclear Information System (INIS)

    The purpose of this study was to design and evaluate an MRI screening protocol for chronic exertional compartment syndrome (CECS) of the lower legs using an in-scanner exercise protocol and novel dual birdcage coil design for improved imaging. Coil and phantom studies: a custom-made dual birdcage coil designed for this protocol was evaluated for uniformity and signal-to-noise ratio (SNR) compared with a conventional phased-array receive-only torso coil and the body coil. Phantom and normal subject studies were performed to confirm coil performance. In-vivo studies: eight unaffected subjects and 42 patients with lower extremity symptoms suggestive of CECS were imaged with the dual birdcage coil and an in-scanner exercise protocol which included imaging at rest, during isometric resisted dorsi flexion, at rest (recovery), during isometric resisted plantar flexion and, again, at rest. Of 42 patients, 14 had confirmed CECS and 28 had lower extremity anomalies attributable to other causes. Ratios of relative T2-weighted signal intensities were calculated for exercise and recovery images compared to baseline after processing of images, including re-registration for motion, smoothing and segmentation to remove bone and pulsation artifacts from blood vessels. Receiver operating characteristic (ROC) analysis showed a threshold for the ratio of relative T2-weighted signal intensity of 1.54 to have a sensitivity of 96%, specificity of 90% and accuracy of 96% for CECS. Patients with CECS had their peak ratio of signal intensity compared with baseline during the first recovery period after isometric dorsi flexion, whereas unaffected subjects and patients with other causes of exercise-induced lower extremity pain reached their peak values during exercise (P < 0.001). We have developed the first in-scanner MRI exercise protocol for the assessment of patients with suspected CECS. The technique shows high accuracy, sensitivity and specificity for diagnosis in this small cohort of

    Progress in prevention as well as drug and interventional therapy has improved the prognosis of patients with cardiovascular disorders. Many patients at risk have advanced coronary artery disease (CAD), have had multiple coronary interventions, and present with significant co-morbidity. Despite adequate risk factor modulation and often several revascularization procedures, some of these patients still have refractory angina pectoris. Apart from advanced CAD and insufficient collateralization, the cause is often endothelial dysfunction. For this situation, one treatment option is neuromodulation. Controlled studies suggest that, in patients with chronic refractory angina pectoris, spinal cord stimulation (SCS) provides a relief from symptoms equivalent to that provided by surgical therapy, but with fewer complications and lower rehospitalization rates. SCS may result in significant long-term pain relief with improved quality of life. In patients with refractory angina undergoing SCS, some studies have shown not only a symptomatic improvement, but also a decrease in myocardial ischemia and an increase in coronary blood flow. Discussion is ongoing as to whether this is a direct effect on parasympathetic vascodilation or merely a secondary phenomenon resulting from increased physical activity following an improvement in clinical symptoms. Results from nuclear medical studies have sparked discussion about improved endothelial function and increased collateralization. SCS is a safe treatment option for patients with refractory angina pectoris, and its long-term effects are evident. It is a procedure without significant complications that is easy to tolerate. SCS does not interact with pacemakers, provided that strict bipolar right-ventricular sensing is used. Use in patients with implanted cardioverter defibrillators is under discussion. Individual testing is mandatory in order to assess optimal safety in each patient. PMID:19178129

    Background ‘Typical’ angina is often used to describe symptoms common among men, while ‘atypical’ angina is used to describe symptoms common among women, despite a higher prevalence of angina among women. This discrepancy is a source of controversy in cardiac care among women. Objectives To redefine angina by (1) qualitatively comparing angina symptoms and experiences in women and men and (2) to propose a more meaningful construct of angina that integrates a more gender-centred approach. Methods Patients were recruited between July and December 2010 from a tertiary cardiac care centre and interviewed immediately prior to their first angiogram. Symptoms were explored through in-depth semi-structured interviews, transcribed verbatim and analysed concurrently using a modified grounded theory approach. Angiographically significant disease was assessed at ≥70% stenosis of a major epicardial vessel. Results Among 31 total patients, 13 men and 14 women had angiograpically significant CAD. Patients describe angina symptoms according to 6 symptomatic subthemes that array along a ‘gender continuum’. Gender-specific symptoms are anchored at each end of the continuum. At the centre of the continuum, are a remarkably large number of symptoms commonly expressed by both men and women. Conclusions The ‘gender continuum’ offers new insights into angina experiences of angiography candidates. Notably, there is more overlap of shared experiences between men and women than conventionally thought. The gender continuum can help researchers and clinicians contextualise patient symptom reports, avoiding the conventional ‘typical’ versus ‘atypical’ distinction that can misrepresent gendered angina experiences.

  2. Relationship between the serologic status of helicobacter pylori with the presence of unstable angina

    International Nuclear Information System (INIS)

    To determine whether unstable angina is co-related to seropositivity to chronic Helicobacter pylori (HP) infection. It is a case control, descriptive study conducted at CCU in Razi Hospital in Ahwaz a city southwest Iran, from 2004 to 2005. We measured serum HP- lgG levels of participants in CCU in a hospital. Blood samples were drawn during study period from 96 patients (mean age 56 years) with Unstable Angina (UA) according to American Heart Association criteria and from 96 participants free of cardiovascular disease (mean age 58 years) and stored at 20 degree C. Serology results were studied in relation to UA. Using chi squared test, odds ratios (OR) and 95% confidence intervals (CI) were calculated, adjusting for age, gender, and established risk factors. Seventy nine (82.3%) of patients with unstable angina and 55(61.1%) in the control group presented a positive anti HP-lgG. Odds ratio was 3 with 95% CI: 1.9 to 4.3. There was significant relation between HP-lgG positivity and unstable angina (P0.05). Our study revealed relationship between seropositivity of HP-lgG and unstable angina. (author)

    The aim of this study was to determine the efficacy of transcutaneous electrical nerve stimulation (TENS) in the treatment of chronic stable severe angina pectoris. In a short-term study the effect of TENS was studied in 10 male patients with angina pectoris (functional class III and IV). All patients had previously been stabilized on long-term maximal oral treatment. The effects of the treatment were measured by means of repeated bicycle ergometer tests. All patients had an increased working capacity (16-85%), decreased ST segment depression and reduced recovery time during TENS. No adverse effects were observed. A long-term study of TENS on similarly selected patients showed beneficial effects in terms of pain reduction, reduced frequency of anginal attacks, increased physical activity and increased working capacity during bicycle ergometer tests. An invasive study was carried out with respect to systemic and coronary hemodynamics and myocardial metabolism during pacing provoked myocardial ischemia in 13 patients. The results showed that TENS led to an increased tolerance to pacing, improved lactate metabolism, less pronounced ST segment depression. A drop in systolic blood pressure during TENS treatment at identical pacing rates indicated a decreased afterload. An increased coronary flow to ischemic areas in the myocardium was supported by the fact that the rate pressure product during anginal pain increased during TENS.

    In previous studies, we verified that exposure to unpredictable chronic mild stress (UCMS) facilitates avoidance responses in the elevated T-maze (ETM) and increased Fos-immunoreactivity in different brain structures involved in the regulation of anxiety, including the dorsal raphe (DR). Since, it has been shown that the DR is composed of distinct subpopulations of serotonergic and non-serotonergic neurons, the present study investigated the pattern of activation of these different subnuclei of the region in response to this stress protocol. Male Wistar rats were either unstressed or exposed to the UCMS procedure for two weeks and, subsequently, analyzed for Fos-immunoreactivity (Fos-ir) in serotonergic cells of the DR. To verify if the anxiogenic effects observed in the ETM could be generalized to other anxiety models, a group of animals was also tested in the light/dark transition test after UCMS exposure. Results showed that the UCMS procedure decreased the number of transitions and increased the number of stretched attend postures in the model, an anxiogenic effect. UCMS exposure also increased Fos-ir and the number of double-labeled neurons in the mid-rostral subdivision of the dorsal part of the DR and in the mid-caudal region of the lateral wings. In the caudal region of the DR there was a significant increase in the number of Fos-ir. No significant effects were found in the other DR subnuclei. These results corroborate the idea that neurons of specific subnuclei of the DR regulate anxiety responses and are differently activated by chronic stress exposure. PMID:26462572

    Full Text Available Tumor immune tolerance can derive from the recruitment of suppressor cell population, including myeloid derived suppressor cells (MDSCs, able to inhibit T cells activity. We identified a significantly expanded MDSCs population in chronic myeloid leukemia (CML patients at diagnosis that decreased to normal levels after imatinib therapy. In addition, expression of arginase 1 (Arg1 that depletes microenvironment of arginine, an essential aminoacid for T cell function, resulted in an increase in patients at diagnosis. Purified CML CD11b+CD33+CD14-HLADR- cells markedly suppressed normal donor T cell proliferation in vitro. Comparing CML Gr-MDSCs to autologous polymorphonuclear leukocytes (PMNs we observed a higher Arg1 expression and activity in PMNs, together with an inhibitory effect on T cells in vitro. Our data indicate that CML cells create an immuno-tolerant environment associated to MDSCs expansion with immunosuppressive capacity mediated by Arg1. In addition, we demonstrated for the first time also an immunosuppressive activity of CML PMNs, suggesting a strong potential immune escape mechanism created by CML cells, which control the anti-tumor reactive T cells. MDSCs should be monitored in imatinib discontinuation trials to understand their importance in relapsing patients.

    Full Text Available Abstract Background Rural-to-urban migration in low- and middle-income countries causes an increase in individual cardiovascular risk. Cost-effective interventions at early stages of the natural history of coronary disease such as angina may stem an epidemic of premature coronary deaths in these countries. However, there are few data on the prevalence of angina in developing countries, whilst the understanding the aetiology of angina is complicated by the difficulty in measuring it across differing populations. Methods The PERU MIGRANT study was designed to investigate differences between rural-to-urban migrant and non-migrant groups in specific cardiovascular disease risk factors. Mass-migration seen in Peru from 1980s onwards was largely driven by politically motivated violence resulting in less 'healthy migrant' selection bias. The Rose angina questionnaire was used to record chest pain, which was classified definite, possible and non-exertional. Mental health was measured using the General Health Questionnaire (GHQ-12. Mantel-Haenszel odds ratios (adjusted for age, sex, cardiovascular disease risk factors and mental health were used to assess the risk of chest pain in the migrant and urban groups compared to the rural group, and further to assess the relationship (age and sex-adjusted between risk factors, mental health and chest pain.

    Because sports injuries in men form most of the available statistics, the reportage of injuries in female athletes is sparse. We describe exertion injuries and disorders in 281 women athletes, all of which hampered athletic training or performances. Sixty per cent of the injuries occurred to girls ages between 12-19 years, and about forty-eight per cent were track and field athletes. The most common sites of injury were the ankle, foot, heel and leg. Osteochondritic disorders were the most typical injuries in the series, and the chronic medical tibial syndrome was the injury that needed surgical treatment most frequently. Overuse injuries seem to differ very little from each other in the events included in this survey. PMID:6797496

    The purpose of this study was to assess the effect of an enriched C-glycosyl flavonoids fraction (EFF-Cp) from Cecropia Pachystachya leaves on behavior, mitochondrial chain function, and oxidative balance in the brain of rats subjected to chronic mild stress. Male Wistar rats were divided into experimental groups (saline/no stress, saline/stress, EFF-Cp/no stress, and EFF-Cp/stress). ECM groups were submitted to stress for 40 days. On the 35th ECM day, EFF-Cp (50 mg/kg) or saline was administrated and the treatments lasted until the 42nd day. On the 41st and 42nd days, the animals were submitted to the splash test and the forced swim test. After these behavioral tests, the enzymatic activity of mitochondrial chain complexes and oxidative stress were analyzed. EFF-Cp reversed the depressive-like behavior induced by ECM. It also reversed the increase in thiobarbituric acid reactive species, myeloperoxidase activity, and nitrite/nitrate concentrations in some brain regions. The reduced activities of the antioxidants superoxide dismutase and catalase in some brain regions were also reversed by EFF-Cp. The most pronounced effect of EFF-Cp on mitochondrial complexes was an increase in complex IV activity in all studied regions. Thus, it is can be concluded that EFF-Cp exerts an antidepressant-like effect and that oxidative balance may be an important physiological process underlying these effects. PMID:26762362

    Objective To examine if the skin microvascular bed is altered and can be modified by enhanced external counterpulsation (EECP) in patients with chronic refractory angina.Methods Twenty patients diagnosed with refractory angina were divided into EECP (n =10) or no EECP (n =10) groups.The data were compared to matched healthy subjects (n =20).The cutaneous forearm microvascular blood flow was measured by Laser-Doppler flowmetry.The vascular responsiveness to iontophoretic administration of acetylcholine (ACh),sodium nitroprusside (SNP) and local skin warming were studied.Measurements of Canadian Cardiovascular Society (CCS)-class,blood pressure and plasma samples were registered.Results EECP patients showed reduced CCS-class compared to no EECP (P < 0.05).Both EECP and no EECP (P < 0.05) groups had decreased systolic blood pressure (SBP) as compared to SBP at baseline (P < 0.05).There was no difference in resting blood flow between the two refractory groups at baseline as well as after EECP and seven weeks of follow-up.Responses to heating,the responses to ACh and SNP in the cutaneous microcirculation were lower in both groups of refractory angina patients as compared to healthy subjects (P < 0.05).EECP patients corresponded positively to the treatment shown by reduced plasma level of soluble interleukin-2 receptor and CCS-class.Conclusions Refractory angina patients have reduced responsiveness in their cutaneous microcirculation to ACh,SNP and heat compared to healthy subjects.Although EECP reduced the CCS-class,this effect was not associated with improvements in responsiveness of the cutaneous microcirculation.

    Full Text Available A angina de Ludwig é uma infecção do espaço submandibular originada, em geral, da infecção do 2º ou 3º molar inferior. Como conseqüência, pode causar mediastinite descendente necrosante, que representa uma forma grave e rara de infecção mediastinal, a qual exige diagnóstico precoce e tratamento cirúrgico para reduzir a alta mortalidade associada a esta doença. Dois casos de mediastinite descendente necrosante pós-angina de Ludwig foram tratados com excelentes resultados em nosso hospital. A drenagem mediastinal transcervical está justificada em pacientes com doença limitada ao mediastino superior. Porém, sepse com comprometimento extenso do mediastino requer drenagem através de toracotomia sem demora.Ludwig's angina is an infection of the submandibular space generally caused by an infection of the 2nd or 3rd lower molar. As a consequence, descending necrotizing mediastinitis, a rare and severe form of mediastinal infection, may occur. The descending necrotizing mediastinitis represents a rare form of mediastinal infection. It presents a high mortality and to decrease that rate it is necessary prompt diagnosis and surgical treatment. Two cases of descending necrotizing mediastinitis due to Ludwig's angina were treated with excellent results in our hospital. The transcervical mediastinal drainage is justified in patients with disease limited to the upper mediastinum. Even so, when there is extensive involvement of the whole mediastinum it is suitable the accomplishment of a wide thoracotomy.

    Unstable angina includes a variety of clinical presentations with a different level of risk for an unfavorable outcome. In this study the authors investigated the prognostic significance of crescendo angina and new-onset angina to discuss management strategies, paying attention to the relevance of baseline clinical characteristics, coronary artery lesions, and left ventricular function, as well as their alterations during atrial pacing. Accordingly coronary arteriographic anatomy and changes in left ventricular volumes and ejection fraction before and during atrial pacing were studied by means of digital subtraction ventriculography in 18 patients with crescendo angina and in 18 patients with new-onset angina. Triple-vessel disease was more frequently observed in crescendo angina (56%; P crescendo angina. The angiographic evidence of intracoronary thrombi was found in 33% (P crescendo angina and in 4% patients with new-onset angina. Compared with the patients with new-onset angina, patients with crescendo angina had higher end-diastolic and end-systolic volumes and lower ejection fraction at rest. At peak pacing, ejection fraction was significantly (P crescendo angina (0.48 +/- 0.06) than in new-onset angina (0.66 +/- 0.04). In crescendo angina, during pacing, the magnitude of velocity of circumferential fiber shortening was significantly decreased as compared with new-onset angina.(ABSTRACT TRUNCATED AT 250 WORDS)

    The purpose of this study was the feasibility, safety and analysis of the ischemic nature of the association of an injection of dipyridamole and an exercise test at low level exertion on an exercise bicycle for 4 minutes. The ischemic nature of this combination was assessed on the basis of three criteria: the onset of angina-type pain, electrical changes and scintigraphic abnormalities. The test could be carried out by all patients and the most common adverse events were headache (6.5%) and heartburn (3.5%). The 17 patients in this study who had one or more stenoses in excess of 70% presented with angina-type pain (3/17); electrical abnormalities (9/17) and scintigraphic abnormalities in all cases. Of the six patients who had lesions between 50 and 70%, 1 presented with angina symptoms, 2 with electrical abnormalities and 5 with scintigraphic abnormalities. Seven patients in this study showed no significant lesions when subjected to coronary artery angiography. However, angina-type pain and electrical signs were observed in 2 cases and one false positive result by scintigraphy. This study shows that it is possible to combine the injection of dipyridamole with an exercise test involving a low level of exertion on an exercise bicycle which gives a good diagnostic value to the CT scan. The frequency of clinical and electrical signs of ischemia makes it necessary to take the same precautions as for a peak exercise test. PMID:8368796

    OBJECTIVE: To ascertain the risk of acute myocardial infarction, invasive cardiac procedures, and mortality among patients with newly diagnosed angina over five years. DESIGN: Incident cohort study of patients with primary care data linked to secondary care and mortality data. SETTING: 40 primary care practices in Scotland. PARTICIPANTS: 1785 patients with a diagnosis of angina as their first manifestation of ischaemic heart disease, 1 January 1998 to 31 December 2001. MAIN OUTCOME MEASURES: Adjusted hazard ratios for acute myocardial infarction, coronary artery bypass grafting, percutaneous transluminal coronary angioplasty, death from ischaemic heart disease, and all cause mortality, adjusted for demographics, lifestyle risk factors, and comorbidity at cohort entry. RESULTS: Mean age was 62.3 (SD 11.3). Male sex was associated with an increased risk of acute myocardial infarction (hazard ratio 2.01, 95% confidence interval 1.35 to 2.97), death from ischaemic heart disease (2.80, 1.73 to 4.53), and all cause mortality (1.82, 1.33 to 2.49). Increasing age was associated with acute myocardial infarction (1.04, 1.02 to 1.06, per year of age increase), death from ischaemic heart disease (1.09, 1.06 to 1.11, per year of age increase), and all cause mortality (1.09, 1.07 to 1.11, per year of age increase). Smoking was associated with subsequent acute myocardial infarction (1.94, 1.31 to 2.89), death from ischaemic heart disease (2.12, 1.32 to 3.39), and all cause mortality (2.11, 1.52 to 2.95). Obesity was associated with death from ischaemic heart disease (2.01, 1.17 to 3.45) and all cause mortality (2.20, 1.52 to 3.19). Previous stroke was associated with all cause mortality (1.78, 1.13 to 2.80) and chronic kidney disease with death from ischaemic heart disease (5.72, 1.74 to 18.79). Men were more likely than women to have coronary artery bypass grafting or percutaneous transluminal coronary angioplasty after a diagnosis of angina; older people were less likely to

    Full Text Available OBJECTIVE - To determine the prevalence of hyperhomocystinemia in patients with acute ischemic syndrome of the unstable angina type. METHODS - We prospectively studied 46 patients (24 females with unstable angina and 46 control patients (19 males, paired by sex and age, blinded to the laboratory data. Details of diets, smoking habits, medication used, body mass index, and the presence of hypertension and diabetes were recorded, as were plasma lipid and glucose levels, C-reactive protein, and lipoperoxidation in all participants. Patients with renal disease were excluded. Plasma homocysteine was estimated using high-pressure liquid chromatography. RESULTS - Plasma homocysteine levels were significantly higher in the group of patients with unstable angina (12.7±6.7 µmol/L than in the control group (8.7±4.4 µmol/L (p<0.05. Among males, homocystinemia was higher in the group with unstable angina than in the control group, but this difference was not statistically significant (14.1±5.9 µmol/L versus 11.9±4.2 µmol/L. Among females, however, a statistically significant difference was observed between the 2 groups: 11.0±7.4 µmol/L versus 6.4±2.9 µmol/L (p<0.05 in the unstable angina and control groups, respectively. Approximately 24% of the patients had unstable angina at homocysteine levels above 15 µmol/L. CONCLUSION - High homocysteine levels seem to be a relevant prevalent factor in the population with unstable angina, particularly among females.

    To investigate the function of dendritic cells (DC) in patients with unstable angina, 10 mL of blood was drawn from 30 subjects. 15 patients diagnosed as having unstable angina and 15 healthy subjects were included in an observation and a control groups respectively. The mononuclear cells were separated from the peripheral blood and cultured in RPMI1640 supplemented with recombinant human granulocyte/macrophage-colony stimulating factor (rh GM-CSF) and recombinant human interleukin-4 (rh IL-4) to induce dendritic cells. The shape and ultrastructure of DC was examined with electronic microscope. The phenotype of DC was analyzed with FACS and the alloantigen presenting capacity of DC was evaluated by mixed lymphocyte reaction (MLR). The expression rate of CD86 of DC in patients with unstable angina was (40.7±3.6) %, which was obviously higher than that of normal DC (29.6±2.5 %) (P<0.001). The capacity of the DCs in unstable angina patients to induce allogenic T cells (OD 2.73±1.10), was significantly higher than that of the normal DC (OD:0.9±0.21) (P<0.005). It is suggested that the function of DC in patients with unstable angina is increased, which may play an important role in the initiation of immune reaction in the plaque.

Angiotomography revealed aneurysm of the ascending aorta, and stenosis of the following vessels: right common iliac artery, renal arteries, and superior mesenteric artery. Those findings supported the diagnosis of mesenteric angina and the interventional approach by use of percutaneous transluminal angioplasty with stent placement.

  11. Management of Stable Angina - Current Guidelines: A Critical Appraisal.

    Science.gov (United States)

    Thadani, Udho

    2016-08-01

    Guidelines provide recommendations to improve patient outcomes, but many of the recommendations made for treating patients with stable angina are opinion based rather than evidence based. Risk stratification to predict patients at an increased risk of myocardial infarction (MI) and sudden ischemic death, and selection of patients for possible revascularization, is based on expert opinion. Randomized trials have compared optimal medical therapy to revascularization, after the coronary anatomy was known, and yet routine coronary angiography to exclude left main disease is not recommended. What exactly is optimal antianginal treatment varies considerably from one country's guideline recommendations to another. None of the antianginal drugs reduce mortality or MI and these drugs are equally effective in treating angina pectoris; and yet beta-blockers and calcium channel blockers are recommended as first line therapy. Double and triple therapy with different classes of antianginal drugs is also expert opinion based rather than evidence based. Recommendations to reduce the incidence of MI and sudden death are appropriate; however the use of a potent, high dose statin, is recommended by AHA/ACC and NICE guidelines for all patients with ischemic heart disease, while the European guidelines recommend a target LDL goal in patients with coronary artery disease (CAD). Management of patients with stable angina pectoris with normal coronary arteries remains ambiguous. This short review critically appraises the recommendations for managing patients with stable angina pectoris. PMID:27638354

    1980-08-01

    Among patients with unstable angina pectoris, those with crescendo angina seem to be at high risk for death and myocardial infarction. We reviewed the clinical, arteriographic, and hemodynamic findings in 218 consecutive catheterized patients with unstable angina. Unstable angina was defined as ischemic cardiac pain at rest associated with transient ECG changes but no evidence for acute myocardial infarction. Patients were divided into two groups according to the duration of symptoms: 134 patients with crescendo angina (new, or increasing, rest pain with previous ischemic symptoms present for more than three months) and 84 with recent onset angina (symptoms present for less than three months). Compared with patients with recent onset symptoms, patients with crescendo angina had more extensive coronary disease and lower ejection fractions, which may explain their poor prognosis.

  15. Physical exertion as a trigger of myocardial infarction and sudden cardiac death.

    Science.gov (United States)

    Mittleman, M A; Siscovick, D S

    1996-05-01

    The data reviewed in this article indicate that physical exertion can trigger the onset of nonfatal myocardial infarction and sudden cardiac death. In addition, it is clear that although the relative risk associated with heavy exertion may be high, the absolute risk is actually quite small. It also is clear that regular exercise reduces the risk of triggering of myocardial infarction and sudden cardiac death by isolated bouts of exertion. Thus, these data provide further support for encouragement of regular exercise, as recommended by the American Heart Association. Such a program is likely to lower the overall risk of myocardial infarction and sudden cardiac death because it may lower the baseline risk and also decrease the relative risk that an episode of exertion will trigger a myocardial infarction or sudden cardiac death. Specific recommendations for patients with a history of myocardial infarction or angina are complex. Patients with coronary artery disease have the same relative risk of myocardial infarction and sudden cardiac death as those with no such history. Because of their elevated and variable baseline risk, however, specific recommendations regarding the risks and benefits of heavy physical exertion must be provided by their individual physicians, acting on recommended guidelines for exercise in such patients.

    We investigate the clinical and prognostic significance of fractal dimension and detrended fluctuation analysis by comparing the group of patients with stable angina pectoris without previous myocardial infarction with the group of age-matched healthy controls. The fractal dimension of the R-R series was determined using the rescaled range (R/S) analysis technique. To quantify fractal longe-range-correlation properties of heart rate variability, the detrended fluctuation analysis (DFA) technique was used. The heart rate variability was characterized by a scaling exponent $\\alpha$, separately for short-term ($$ 11 beats) time scales. The results of data sets show the existence of crossover phenomena between short-time scales. The short-term fractal scaling exponent was significantly lower in patients with stable angina pectoris.

    Full Text Available Guillaume Marquis-Gravel, Jean-Claude TardifMontreal Heart Institute, Université de Montréal, Montreal, Quebec, CanadaIntroduction: Stable angina pectoris (SAP is a widely prevalent disease affecting 30 000 to 40 000 per million people in Europe and the US. SAP is associated with reductions in quality of life and ability to work, and increased use of healthcare resources. Ivabradine is a drug with a unique therapeutic target, the If current of the sinus node, developed for the treatment of cardiovascular diseases including SAP. It has an exclusive heart rate reducing effect, without any negative effect on left ventricular function or coronary vasodilatation.Aims: The aim of this paper is to review the evidence concerning the use of ivabradine in the treatment of SAP.Evidence review: Ivabradine is an effective antianginal and antiischemic drug, not inferior to the beta blocker atenolol and the calcium channel antagonist (CCA amlodipine. It decreases the frequency of angina attacks and increases the time to anginal symptoms during exercise. Because of its exclusive chronotropic effect, ivabradine is not associated with the typical adverse reactions associated with beta blockers or other antianginal drugs.Clinical value: Clinical evidence shows that ivabradine is a very good antiischemic and antianginal agent, being as effective as beta blockade and CCA therapy in controlling myocardial ischemia and symptoms of stable angina. Ongoing studies will determine the potential of ivabradine to improve morbidity and mortality in coronary artery disease and heart failure.Key words: evidence, If current, ivabradine, outcomes, stable angina pectoris, treatment

    Full Text Available Secretory leukoprotease inhibitor (SLPI is an anti-inflammatory protein present in respiratory secretions. Whilst epithelial cell SLPI is extensively studied, neutrophil associated SLPI is poorly characterised. Neutrophil function including chemotaxis and degranulation of proteolytic enzymes involves changes in cytosolic calcium (Ca2+ levels which is mediated by production of inositol 1,4,5-triphosphate (IP3 in response to G-protein-coupled receptor (GPCR stimuli. The aim of this study was to investigate the intracellular function of SLPI and the mechanism-based modulation of neutrophil function by this antiprotease. Neutrophils were isolated from healthy controls (n=10, individuals with cystic fibrosis (CF (n=5 or chronic obstructive pulmonary disease (COPD (n=5. Recombinant human SLPI significantly inhibited fMet-Leu-Phe (fMLP and interleukin(IL-8 induced neutrophil chemotaxis (P<0.05 and decreased degranulation of matrix metalloprotease-9 (MMP-9, hCAP-18, and myeloperoxidase (MPO (P<0.05. The mechanism of inhibition involved modulation of cytosolic IP3 production and downstream Ca2+ flux. The described attenuation of Ca2+ flux was overcome by inclusion of exogenous IP3 in electropermeabilized cells. Inhibition of IP3 generation and Ca2+ flux by SLPI may represent a novel anti-inflammatory mechanism, thus strengthening the attractiveness of SLPI as a potential therapeutic molecule in inflammatory airway disease associated with excessive neutrophil influx including CF, non-CF bronchiectasis, and COPD.

    Background Activation of glial cells and the extracellular signal-regulated kinase (ERK) signaling pathway play an important role in the development and maintenance of neuropathic pain.Curcumin can alleviate the symptom of inflammatory pain by inhibiting the production and release of interleukin and tumor necrosis factor.However,whether curcumin affects neuropathic pain induced by nerve injury and the possible mechanism involved are still unknown.This study investigated the effects of tolerable doses of curcumin on the activation of astrocytes and ERK signaling in the spinal dorsal horn in rat model of neuropathic pain.Methods Adult male Sprague-Dawley rats were randomly divided into three groups:a control (sham operated) group,and chronic constriction injury groups (to induce neuropathic pain) that were either untreated or treated with curcumin.Thermal and mechanical hyperalgesia thresholds were measured.The distribution and morphological changes of astrocytes were observed by immunofluorescence.Western blotting was used to detect changes in the expression of glial flbrillary acid protein (GFAP) and phosphorylated ERK.Results Injured rats showed obvious mechanical allodynia and thermal hyperalgesia.The number of GFAP-positive astrocytes,and the fluorescence intensity of GFAP were significantly increased in the spinal dorsal horn of injured compared with control rats.The soma of astrocytes also appeared hypertrophied in injured animals.Expression of GFAP and phosphorylated ERK was also significantly increased in the spinal dorsal hom of injured compared with control rats.Curcumin reduced the injury-induced thermal and mechanical hyperalgesia,the increase in the fluorescence intensity of GFAP and the hypertrophy of astrocytic soma,activation of GFAP and phosphorylation of ERK in the spinal dorsal horn.Conclusions Curcumin can markedly alleviate nerve injury-induced neuropathic pain in rats.The analgesic effect of curcumin may be attributed to its inhibition of

    Full Text Available Coronary cameral fistulas are abnormal communications between a coronary artery and a heart chamber or a great vessel which are reported in less than 0.1% of patients undergoing diagnostic coronary angiography. All three major coronary arteries are even less frequently involved in fistula formation as it is the case in our patient. A 68-year-old woman was admitted to cardiology clinic with complaints of exertional dyspnea and angina for two years and a new onset palpitation. Standard 12-lead electrocardiogram revealed atrial fibrillation (AF with a ventricular rate of 114 beat/minute and accompanying T wave abnormalities and minimal ST-depression on lateral derivations. Transthoracic echocardiographic examination was normal except for diastolic dysfunction, minimally mitral regurgitation, and mild to moderate enlargement of the left atrium. Sinus rhythm was achieved by medical cardioversion with amiodarone infusion. Coronary angiography revealed diffuse and multiple coronary-left ventricle fistulas originating from the distal segments of both left and right coronary arterial systems without any stenosis in epicardial coronary arteries. The patient’s symptoms resolved almost completely with medical therapy. High volume shunts via coronary artery to left ventricular microfistulas may lead to increased volume overload and subsequent increase in end-diastolic pressure of the left ventricle and may cause left atrial enlargement.

    Full Text Available Incorporating physical activity and exertion into pervasive gaming applications can provide health and social benefits. Prior research has resulted in several prototypes of pervasive games that encourage exertion as interaction form; however, no detailed critical account of the various approaches exists. We focus on networked exertion games and detail some of our work while identifying the remaining issues towards providing a coherent framework. We outline common lessons learned and use them as the basis for generalizations for the design of networked exertion games. We propose possible directions of further investigation, hoping to provide guidance for future work to facilitate greater awareness and exposure of exertion games and their benefits.

    Background Resistin, a novel adipokine linked to insulin resistance and obesity in rodents, which is derived mainly from macrophages and identified in atheromas in human, has been shown to play a potential role in atherosclerosis.Resistin levels were reported to increase in coronary artery disease (CAD), while data concerning resistin in different stages of CAD in Chinese people are lacking. The aim of this study was to assess whether plasma concentrations of resistin differed between patients with unstable and stable angina pectoris.Methods Plasma resistin levels were determined by means of enzyme-linked immunosorbent assay (ELISA) in 46 patients with unstable angina (UAP), 37 with stable angina (SAP) and 31 control subjects.Results Plasma concentrations of resistin were significantly increased in UAP group (geometric mean (interquartile range) 12.09 ng/ml (8.40, 18.08)) in comparison with SAP (9.04 ng/ml (7.09, 11.44)) and control groups (8.71 ng/ml (6.58,11.56)). No differences in resistin levels were found between patients with SAP and controls. We also found that plasma resistin positively correlated with leukocyte counts (r=0.21, P=0.027), high sensitive C-reactive protein (hs-CRP) (r=0.25,P=0.008), and endothelin-1 (r=0.21, P=0.025) after adjustment for age, sex and BMI.Conclusion Resistin may be involved in the development of CAD by influencing systemic inflammation and endothelial activation.

    Full Text Available Relapsing polychondritis (RP is a severe progressive inflammatory condition involving cartilaginous structures and caused by an autoimmune process, for which there is no confirmatory serological biomarker and which still is diagnosed on a mainly clinical basis. RP has been associated with many diseases like Sweet’s syndrome, Behcet’s disease, rheumatoid arthritis, and other autoimmune disorders. We attempt to describe here a unique case of a 38-year-old female with a high-grade fever, sore throat, difficulty in swallowing, hoarseness of the voice, and found to have signs of tongue swelling and inflammation of the oral cavity that mimicked Ludwig’s angina, necessitating antibiotic use. On careful re-evaluation the patient was diagnosed to have relapsing polychondritis based on auricular and respiratory tract chondritis and response to steroids. The purpose of this report is to emphasize the fact that careful clinical assessment is needed to diagnose RP, which may be misdiagnosed as Ludwig’s angina.

    Vasospastic angina is caused by sudden occlusive vasoconstriction of a segment of an epicardial artery, which can present with a wide spectrum of clinical scenario. We report the cases of two patients diagnosed with vasospastic angina, with one of which presenting with sud-den cardiac arrest, while the other presenting with a relatively benign syncope. But both of them have J waves formation on ECG during active ischemia. The diagnosis and management of vasospastic angina, as well as the proposed clinical significance of J waves during coro-nary spasm are discussed.

    Full Text Available Myocardial ischemia in pediatric population is uncommon and usually due to congenital heart disease or extracardiac conditions leading to poor coronary perfusion. A 6-day-old newborn presented with respiratory distress and signs of heart failure. ECG, echocardiography, and laboratory results were consistent with myocardial ischemia. Coronary angiography was performed to exclude anomalous origin of coronary arteries, showing normal coronary artery origin and course. Thrombophilia and extra-cardiac causes were ruled out. Clinical conditions improved with mechanical ventilation and diuretics, enzyme levels lowered, repolarisation and systolic function abnormalities regressed, but ischemic electrocardiographic and echocardiographic signs still presented during intense crying. Becaues of suspicion of microvascular angina, therapy with ASA and beta-blocker was started. At 5 month followup, the baby was in good clinical condition and no more episodes were recorded. We believe it is an interesting case, as no similar cases have been recorded till now.

    The plasma levels of inflammatory cytokine interleukin-6 (IL-6) and anti-inflammatory cytokine interleukin-10 (IL-10) in the patients with unstable angina or stable angina were determined and compared. In 30 patients with unstable angina and 22 patients with stable angina, plasma levels of IL-10 and IL-6 were detected by ELISA and plasma lipid parameters by lipid research clinical methods respectively. The results showed plasma levels of IL-10 were significantly lower in unstable angina group than in stable angina group (P=0. 005), while those of IL-6 were significantly increased in unstable angina group as compared with those in stable angina group (P = 0. 039).There was a significantly negative correlation between IL-10 and IL-6 in patients with unstable angina (r=-0.41, P=0. 003). In the unstable angina group, IL-6 levels were obviously positively correlated with TC (r=0. 314, P=0. 023), but not with TG and HDL. There were no significant correlations between IL-10 and plasma lipid parameters. It was suggested that the decreased IL-10and increased IL-6 might be associated with the atheromatous plaque stability and progression of coronary heart diseases. IL-10 may play an important role in preventing coronary vascular lesions.

    Full Text Available Dental infections, such as periodontitis, associate with atherosclerosis and its complications. We studied a cohort followed-up since 1985 for incidence of angina pectoris with the hypothesis that calculus accumulation, proxy for poor oral hygiene, links to this symptom.In our Swedish prospective cohort study of 1676 randomly selected subjects followed-up for 26 years. In 1985 all subjects underwent clinical oral examination and answered a questionnaire assessing background variables such as socio-economic status and pack-years of smoking. By using data from the Center of Epidemiology, Swedish National Board of Health and Welfare, Sweden we analyzed the association of oral health parameters with the prevalence of in-hospital verified angina pectoris classified according to the WHO International Classification of Diseases, using descriptive statistics and logistic regression analysis.Of the 1676 subjects, 51 (28 women/23 men had been diagnosed with angina pectoris at a mean age of 59.8 ± 2.9 years. No difference was observed in age and gender between patients with angina pectoris and subjects without. Neither was there any difference in education level and smoking habits (in pack years, Gingival index and Plaque index between the groups. Angina pectoris patients had significantly more often their first maxillary molar tooth extracted (d. 16 than the other subjects (p = 0.02. Patients also showed significantly higher dental calculus index values than the subjects without angina pectoris (p = 0.01. Multiple regression analysis showed odds ratio 2.21 (95% confidence interval 1.17-4.17 in the association between high calculus index and angina pectoris (p = 0.015.Our study hypothesis was confirmed by showing for the first time that high dental calculus score indeed associated with the incidence of angina pectoris in this cohort study.

    The purpose of this study was to examine perceived exertion responses during concentric and eccentric elbow flexor contractions between young adult men and women. Thirty healthy young adults participated in two experimental sessions. During the first session, subjects performed five concentric isokinetic maximal voluntary contractions (MVC) of elbow flexion, followed by nine, randomly-ordered sub-maximal contractions (10-90% MVC). The same procedures were repeated during the second session, with the exception that eccentric contractions were performed. Subjects rated their perceived exertion following the sub-maximal contractions with the Borg category-ratio scale. Perceived exertion was significantly (p<0.05) less than equivalent values on the CR-10 scale at intensities greater than, and equal to, 30% MVC. A three-factor interaction between 30-40% MVC indicated that perceived exertion increased more during the eccentric, than concentric, contractions in women, while the opposite pattern was evident for the men. There were no significant contraction mode or gender differences. Power function modeling revealed that perceived exertion increased in a negatively accelerating manner, except for the men performing eccentric exercise. Perceived exertion increases in a similar non-linear manner between men and women during concentric contractions, while men exhibited a statistically linear pattern during eccentric contractions.

    Platelet activation, with the subsequent generation of Thromboxane (Tx) A2, has been implied as a possible cause of resting as well as exercise induced myocardial ischemia. To verify the latter hypothesis, we measured the exercise release of TxB2, the stable metabolite of TxA2, in 9 patients with exertional angina and left anterior descending coronary artery disease. Three of the patients also suffered from angina at rest, due to coronary vasospasm. The great cardiac vein flow, venous efflux from the myocardial territory supplied by the left anterior descending, was determined by the thermodilution technique in the basal conditions, at peak exercise when angina and/or significant ST changes occurred, and 20 min after exercise. Simultaneous blood samples were drawn from the great cardiac vein and a peripheral artery for TxB2 measurements. Regional coronary resistances were calculated as the ratio of mean arterial pressure and coronary flow. At peak exercise the great cardiac vein flow increased and regional coronary resistances decreased in all patients, except in one who showed exercise induced coronary spasm. An increase in TxB2 release was found in 3 patients, a decrease in 3, while the remaining 3 patients did not show significant changes. After exercise the great cardiac vein flow and regional coronary resistances returned to control values in all, whereas both great cardiac vein and arterial TxB2 levels were increased in 6 patients. Our data show that no apparent relation exists between exercise-induced changes in coronary resistances and generation of TxB2.(ABSTRACT TRUNCATED AT 250 WORDS)

    The coexistence of different clinical syndromes due to atherosclerosis in different organs is not rare and emphasizes the diffuse nature of this vascular process. Although renovascular disease may cause hypertension and/or renal insufficiency, it may also occur in the absence of the usual clinical markers that suggest renovascular hypertension. We report a patient with stable coronary anatomy who presented with crescendo angina pectoris. Diagnosis of renovascular hypertension was made by screening renal angiography at the time of the cardiac catheterization. Renal artery stenting resulted in stabilization of the coronary syndrome and obviated the need for further coronary intervention. To our knowledge, this is the first case of renovascular hypertension precipitating an unstable coronary syndrome in a patient with documented stable coronary anatomy. Review of the literature supports that patients undergoing cardiac catheterization are a high risk population for renovascular disease, particularly in the presence of other predictive factors such as documented coronary artery disease, older age, female gender, congestive heart failure, peripheral vascular disease, renal insufficiency, and smoking. Firm recommendations for routine screening renal angiography in patients undergoing peripheral or coronary angiography will need further studies.

    High sympathetic tone and cardiac autonomic neuropathy (CAN) are associated with major adverse cardiac events (MACE). We have shown ranolazine (RAN) improves autonomic function. RAN was introduced to 51 successive anginal CD patients (RANCD). A control group of 54 successive nonanginal CD patients (NORANCD) continued baseline therapy. Mean study duration was 6.1 years, which included semi-annual autonomic function measures (ANX 3.0, ANSAR Medical Technologies, Inc., Philadelphia, PA) and yearly myocardial perfusion SPECT studies (MPI). MACE were experienced by 29% RANCD patients versus 46% NORANCD patients (p = 0.0105). The patients from both groups with abnormal parasympathetic and sympathetic (P&S) measures and MACE totaled 52 of those patients with MACE versus 17% of those patients without MACE (p = 0.0274). Abnormal MPI was demonstrated in 35% of those with abnormal (P&S) measures and MACE versus 12% without MACE. Sympathovagal balance (SB) was lower, indicating higher, relative parasympathetic tone (known to be cardioprotective) in the RANCD group. Acute coronary syndromes occurred 4.5 times as often in NORANCD patients. High SB occur more frequently than abnormal MPI in CD patients experiencing MACE. In addition to increased myocardial blood flow as its proposed mechanism of angina relief, RAN improves P&S measures, a potentially new mechanism whereby RAN improves outcomes.

    Full Text Available Abstract Background We performed this study to develop a new scoring system to stratify different levels of risk in patients admitted to hospital with a diagnosis of unstable angina (UA, which is a complex syndrome that encompasses different outcomes. Many prognostic variables have been described but few efforts have been made to group them in order to enhance their individual predictive power. Methods In a first phase, 473 patients were prospectively analyzed to determine which factors were significantly associated with the in-hospital occurrence of refractory ischemia, acute myocardial infarction (AMI or death. A risk score ranging from 0 to 10 points was developed using a multivariate analysis. In a second phase, such score was validated in a new sample of 242 patients and it was finally applied to the entire population (n = 715. Results ST-segment deviation on the electrocardiogram, age ≥ 70 years, previous bypass surgery and troponin T ≥ 0.1 ng/mL were found as independent prognostic variables. A clear distinction was shown among categories of low, intermediate and high risk, defined according to the risk score. The incidence of the triple end-point was 6 %, 19.2 % and 44.7 % respectively, and the figures for AMI or death were 2 %, 11.4 % and 27.6 % respectively (p Conclusions This new scoring system is simple and easy to achieve. It allows a very good stratification of risk in patients having a clinical diagnosis of UA. They may be divided in three categories, which could be of help in the decision-making process.

    Twelve cases of myocardial infarction as related to strenuous exertion are presented with the pathological findings in several of these cases. Three cases with coronary arteriography are also presented. The pathology of coronary arteriosclerotic plaques and the vulnerability to acute injury is reviewed and discussed. It is concluded that strenuous exertion can cause acute injury to coronary artery plaques due to the unusual stressful whip-like action to which coronary arteries are subject. These injuries may initiate as cracks in the plaques or subintimal hemorrhages and proceed to coronary occlusion and ultimate myocardial infarction. With this concept in mind we use the term of "crack in the plaque" (Black's Crack in the Plaque) to account for the sudden appearance of clinical coronary artery disease appearing during or shortly after exertion, or other stressful situations in patients without previous existing evidence of clinical coronary artery disease. This could also account for exacerbation of symptoms or death occurring after exertion in previously quiescent asymptomatic known coronary artery disease subjects. This concept may explain some of the puzzling features of coronary disease.

    It is important to measure troponin levels when acute myocardial infarct is suspected. Many other factors that affect the heart can cause an increase in troponin levels, for example extreme physical exertion. Recent studies have shown that more normal physical activity can also lead to increase in troponin levels in healthy individuals.

    Ludwig's angina is a serious and rapidly progressive infectious process that spreads through the floor of the mouth and neck. In this paper we present an infrequent case of a patient who suffered an odontogenic infection with poor response to the previous treatment, which evolved towards a Ludwig's angina combined with ketoacidosis in the context of a diabetes mellitus not known before. According to the literature reviewed, this case report represents the first contribution of a Ludwig's angina and ketoacidosis as an initial manifestation of a diabetes mellitus. The airway management, the antibiotic prescription and the surgical drainage allowed the healing of the patient without medical complications. Factors of co-morbidity like the diabetes mellitus together with focus tooth of infection may eventually turn into serious medical complications as the diabetic ketoacidosis and develop potentially lethal cervical infections.

    Emergency departments (ED) in the United States see over eight million cases of chest pain annually. While a cardinal symptom of acute coronary syndrome (ACS), multiple emergent and non-emergent causes can attribute to chest pain. This case-based perspective describes the different sex-specific causes of angina seen in ED patients. Once coronary artery disease (CAD) is ruled out with standard protocols, microvascular dysfunction is perhaps the most prevalent but under-diagnosed cause of non-CAD related angina in ED patients. Additional causes include coronary artery spasm, coronary artery dissection, coronary artery endothelial dysfunction and myocardial bridging. Non-CAD related angina is associated with persistent chest pain causing poor function, quality of life, and recidivism. Clinicians should consider additional diagnostics to routinely screen for non-CAD related causes of angina in patients with recurrent chest pain. Future work is needed to better define the epidemiological, clinical, biological, and genetic correlates of microvascular dysfunction in these patients. PMID:27354848

    Vascular endothelial growth factor (VEGF) induces mobilization of endothelial progenitor cells (EPCs) with the capacity for proliferation and differentiation into mature endothelial cells, thus contributing to the angiogenic process. We sought to assess the behavior of EPCs in patients with ischemic heart disease and refractory angina who received an intramyocardial injections of 2000 µg of VEGF 165 as the sole therapy. The study was a subanalysis of a clinical trial. Patients with advanced ischemic heart disease and refractory angina were assessed for eligibility. Inclusion criteria were as follows: signs and symptoms of angina and/or heart failure despite maximum medical treatment and a myocardial ischemic area of at least 5% as assessed by single-photon emission computed tomography (SPECT). Exclusion criteria were as follows: age > 65 years, left ventricular ejection fraction < 25%, and a diagnosis of cancer. Patients whose EPC levels were assessed were included. The intervention was 2000 µg of VEGF 165 plasmid injected into the ischemic myocardium. The frequency of CD34+/KDR+ cells was analyzed by flow cytometry before and 3, 9, and 27 days after the intervention. A total of 9 patients were included, 8 males, mean age 59.4 years, mean left ventricular ejection fraction of 59.3% and predominant class III angina. The number of EPCs on day 3 was significantly higher than that at baseline (p = 0.03); however, that on days 9{sup th} and 27{sup th} was comparable to that at baseline. We identified a transient mobilization of EPCs, which peaked on the 3th day after VEGF 165 gene therapy in patients with refractory angina and returned to near baseline levels on 9{sup th} and 27{sup th}days.

The frequency of CD34+/KDR+ cells was analyzed by flow cytometry before and 3, 9, and 27 days after the intervention. A total of 9 patients were included, 8 males, mean age 59.4 years, mean left ventricular ejection fraction of 59.3% and predominant class III angina. The number of EPCs on day 3 was significantly higher than that at baseline (p = 0.03); however, that on days 9th and 27th was comparable to that at baseline. We identified a transient mobilization of EPCs, which peaked on the 3th day after VEGF 165 gene therapy in patients with refractory angina and returned to near baseline levels on 9th and 27thdays

    Full Text Available Die instabile Angina pectoris führt oft zum akuten Myokardinfarkt. Da die Lipid-Peroxidation im Verdacht steht, chronische und akute Ereignisse der Atherosklerose und der koronaren Herzkrankheit zu fördern, untersuchten wir die Lipid-Peroxidations-Parameter und alpha-Toco-pherol-Spiegel bei 100 KHK-Patienten und verglichen sie mit denen einer entprechenden Kontrollgruppe. 50 konsekutive Patienten mit stabiler Angina pectoris (SAP und 50 konsekutive Patienten mit instabiler Angina pectoris (IAP wurden untersucht und mit 100 klinisch gesunden Personen verglichen. Zusätzlich zur herkömmlichen Lipid- und Lipoprotein-Analyse wurden die Lipid-Peroxidations-Produkte als Hydroperoxide und Thiobarbituric acid reactive substances (TBARS gemessen. Die konjugierten Diene wurden nur bei den Patienten bestimmt. Da alpha-Tocopherol eines der wichtigsten Antioxidantien ist, wurde es ebenfalls quantifiziert. Wie erwartet hatten die Patienten wesentlich höhere Cholesterin-, Triglyzerid-, LDL-C- und Lp(a-Spiegel und niedrigere HDL-C-Spiegel als die Kontrollgruppe. Als die Patienten in Gruppen mit stabiler und instabiler Angina pectoris geteilt wurden, waren Peroxide und TBARS in der letzteren Gruppe wesentlich höher als bei den anderen Patienten und der Kontrollgruppe. Auch konjugierte Diene waren eindeutig höher bei den Patienten mit instabiler Angina pectoris. Der alpha-Tocopherol-Gesamtspiegel war in allen 3 Gruppen vergleichbar, aber der alpha-Tocopherol-Gehalt pro LDL-Partikel war bei den Patienten mit IAP am niedrigsten, gefolgt von denen mit SAP und der Kontrollgruppe. Wir schließen daraus, daß die Lipid-Peroxidations-Parameter bei Patienten mit IAP erhöht sind und SAP-Patienten von IAP-Patienten unterscheiden.

    The treatment of patients with angina pectoris refractory to medical therapy and unsuitable for revascularization procedures has yet not been well standardized. Previous retrospective studies and small prospective studies have suggested beneficial effects of spinal cord stimulation (SCS) in these patients. We created a Prospective Italian Registry of SCS to evaluate the short- and long-term clinical outcome of patients who underwent SCS device implantation because of severe refractory angina pectoris. Overall, 104 patients were enrolled in the registry (70 men, aged 68 +/- 17 years), most of whom (83%) had severe coronary artery disease. Average follow-up was 13.2 +/- 8 months. Overall, 17 patients (16%) died, 8 (8%) due to cardiac death. Among clinical variables, only age was found to be significantly associated both with total mortality (p = 0.04) and cardiac mortality (p = 0.02) on Cox regression analysis. A significant improvement of anginal symptoms (> or =50% reduction of weekly anginal episodes, compared with baseline) occurred in 73% of patients, and Canadian Cardiovascular Society angina class improved by > or =1 class in 80% and by > or =2 classes in 42% of patients, with a relevant reduction in the rate of hospital admission and days spent in the hospital because of angina (p <0.0001 for both). No life-threatening or clinically serious complications were observed. The most frequent side effect consisted of superficial infections, either at the site of puncture of electrode insertion or of the abdominal pocket, which occurred in 6 patients. In conclusion, our prospective data point out that SCS can be performed safely and is associated with a sustained improvement of anginal symptoms in a relevant number of patients with refractory stable angina pectoris.

    Thrombus formation over a fissured coronary atheromatous plaque has been shown by post mortem histological examination to be the pathophysiological mechanism responsible for myocardial ischaemia in those patients who died following a crescendo pattern of angina. Histological examination of plaques responsible for a crescendo pattern of angina in patients who do not die has not been available until recently. We describe two patients who presented with a crescendo pattern of angina. A new technique of coronary revascularization, directional coronary atherectomy, produced symptomatic relief and resolution of myocardial ischaemia. Histological examination of material from the stenosis responsible for their myocardial ischaemia, obtained using this technique, confirmed thrombus formation overlying a fissured atheromatous plaque.

    Coronary revascularisation is the treatment of choice in patients with stable angina who have significant stenoses. From a pathophysiological point of view, however, mitigation of angina is to be expected only in the presence of reversible ischaemia. Therefore it was the aim of this study to examine the effect of revascularisation on stable angina in relation to the myocardial perfusion imaging (MPI) pattern prior to intervention. Three hundred and eighty-four patients (58.0{+-}8.8 years) referred for angiography underwent MPI. Prior to MPI and at 2-year follow-up, patients were classified as having typical angina, atypical angina, non-cardiac chest pain or no pain, and the severity of chest pain was graded according to the Canadian Cardiovascular Society (CCS) criteria. The patients themselves estimated their pain on a visual analogue scale. Management was based on symptoms and angiographic findings, since the results of MPI were not communicated. Among the 240 patients who were not revascularised, 79% had typical or atypical angina at study entrance versus 40% at follow-up. In comparison, 93% of the 144 revascularised patients had typical or atypical angina before intervention versus only 36% at follow-up. This additional advantage of invasive therapy was present only in patients with reversible defects; revascularisation had no additional effect in patients with normal perfusion or irreversible defects. Similarly, additional, significant reductions in CCS class and visual analogue score were observed exclusively in patients with reversible defects. In patients referred for coronary angiography owing to known or suspected stable angina, revascularisation was significantly more effective than medical treatment exclusively in patients with reversible ischaemia.

    A 27-year-old female patient with mediastinal abscess and thoracic empyema developed from angina tonsillaris was studied clinically on the manifestations, computed tomography (CT) scan, and the treatment process. The patient was admitted to hospital with a history of fever, sore throat, and chest and neck pain. CT showed air and air-fluid levels within mediastinal dense fatty planes that extended from the thoracic inlet to the sub-carinal region and left pleural empyema. She was cured by mediastinal drainage and extensive debridement of the necrotic tissue under operation and broad spectrum antibiotics treatment. Angina tonsillaris induced acute mediastitis and mediastinal abscess is a relatively rare inflammatory pathology but actually a fatal situation for its high mortality rate. CT scanning is extremely useful for early diagnosis and surgical treatment planning. The main treatment is aggressive and adequate surgical drainage of the abscess and intravenous effective antibiotic treatment.

  12. Chest pain and angina pectoris - or the ugly swan and the beautiful duckling

    van Tellingen, C.

    2010-01-01

    The original description of Heberden’s angina pectoris is put forward to stress the importance of proper history-taking in identifying patients. In a market-driven approach to improve cost-effectiveness in healthcare, angina pectoris as an entity seems stripped to its bare minimum: chest and pain. The diagnostic yield of exercise testing, however, depends on the pre-test likelihood of disease and therefore knowledge of its clinical utility and pitfalls is essential to refine an initial and subjective diagnosis based on anamnesis. Nowadays chest pain units attempt to improve diagnostic accuracy by submitting all sorts of patients to the (stress) test. In the end protocol-driven policies like these may very well prove to be contraproductive when fundamentals are ignored. (Neth Heart J 2010;18:561–4.) PMID:21113382

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

    2011-02-01

    Vigorous physical activity increases the risk of sudden cardiac death (SCD) and acute myocardial infarction (AMI) but there is no standard definition as to what constitutes an exertion-related cardiac event, specifically the time interval between physical exertion and cardiac event. A systematic review of studies related to exertion-related cardiac events was performed and the time interval between exertion and the event or the symptoms leading to the event was looked for in all the articles selected for inclusion. A total of 12 of 26 articles "suggested" or "defined" exertion-related events as those events whose symptoms started during or within 1 h of exertion. Others used definitions of 0.5 h, 2 h, "during exertion", "during or immediately post exertion" and "during or within several hours after exertion". It is suggested, therefore, that the definition of an exertion-related cardiac event be established as a cardiac event in which symptoms started during or within 1 h of physical exertion.

    Objective:To study the efficacy of fluoxetine combined with conventional drug treatment on unstable angina patients complicated with depression. Methods:120 cases of unstable angina patients with depression were randomly divided into two groups. The anti-depression group received fluoxetine combined with conventional drug therapy; the conventional group received conventional drug therapy. Then contents of monoamine neurotransmitters and their metabolites, antioxidants and inflammatory mediators of both groups were compared. Results:Serum monoamine neurotransmitters NE, 5-HT and HA levels of the anti-depression group were higher than those of the conventional group and metabolites 5-HIAA and HVA contents were lower than those of the conventional group; serum SOD, CAT, GSH and HSP-70 contents of the anti-depression group were higher than those of the conventional group, and hs-CRP, MMP9, MCP1 and HMGB1 contents were lower than those of the conventional group. Conclusion:Fluoxetine combined with conventional drug therapy can increase the contents of monoamine neurotransmitters and antioxidants, and reduce oxidative stress response and inflammatory response; it is an ideal method for treating unstable angina complicated with depression.

    Full Text Available To evaluate the beneficial and adverse effects of breviscapine injection in combination with Western medicine on the treatment of patients with angina pectoris. The Cochrane Central Register of Controlled Trials, Medline, Science Citation Index, EMBASE, the China National Knowledge Infrastructure, the Wanfang Database, the Chongqing VIP Information Database and the China Biomedical Database were searched to identify randomized clinical trials (RCTs that evaluated the effects of Western medicine compared to breviscapine injection plus Western medicine on angina pectoris patients. The included studies were analyzed using RevMan 5.1.0 software. The literature search yielded 460 studies, wherein 16 studies matched the selection criteria. The results showed that combined therapy using Breviscapine plus Western medicine was superior to Western medicine alone for improving angina pectoris symptoms (OR=3.77, 95% Cl: 2.76~5.15 and also resulted in increased electrocardiogram (ECG improvement (OR=2.77, 95% Cl: 2.16~3.53. The current evidence suggests that Breviscapine plus Western medicine achieved a superior therapeutic effect compared to Western medicine alone.

    Quality of life was evaluated in patients with unstable angina before and after surgical therapy with spinal cord electrical stimulation (SCES). Overall 12 patients were evaluated, with quantification of the mean weekly number of anginal attacks, the degree of effort provoking them and the Nottingham Health Profile (NHP). The criteria of inclusion in the study were: angina grade IV, resistant to drug therapy and without indication of surgery. The mean follow-up period was 9.8 +/- 8.2 months. A significant reduction in the weekly number of anginal attacks (preoperative 30.9 +/- 14.5; postoperative 9.6 +/- 8.2; p less than 0.01); improvement in functional class (p less than 0.001), and significant improvement (p greater than 0.05) in the pain, energy, sleep, social isolation and emotional reactions areas of NHP were observed. It was concluded that SCES is a useful procedure in patients with unstable angina untreatable by other medical or surgical methods, as it reduces the number of anginal attacks and increases quality of life of the patients without additional risk.

    Full Text Available A case of a 22-year old soldier, with a history of pain in the leg during heavy exercise, which desisted at rest, was presented. One day before admission, the patient had felt an extreme exertion-induced pain in his right leg which had not lessened at rest. At the same time, the patient noticed persistent severe leg edema. On physical examination, the intracompartmental pressure was 62 mmHg (>30 mmHg. The patient was urgently operated on, and fasciotomy according to Mubarak was used. At second surgery, the debridement of the muscles of the posterior group of the leg, and the evacuation of hemathoma from the anterior and lateral group of the right leg muscles were perfomed. Postoperative recovery was uneventful. Fasciotomy wounds were closed within 14 days of the surgery. The complete physical treatment was done. Follow-up examinations 1, 3, and 6 months afterwards were satisfactory. The soldier completed his compulsory military service without any sequelae. Laboratory results were normal. Overlooked, unrecognized or surgically untreated compartment syndrome can cause severe damage, including even the loss of the extremity.

    Chinese herbal medicine (CHM) has been widely used as an adjunct to western medicine in treating angina in China. We carried out this systematic review to evaluate the effectiveness of CHM on top of western medicine for angina. This meta-analysis included 46 randomized control trials with 4212 patients. For trials that included stable angina patients, the CHM group had significant lower incidence of total heart events (relative risk (RR) = 0.50, 95% confidence interval (CI) 0.33-0.78), myocardial infarction (RR = 0.32, 95% CI 0.14-0.72), heart failure (RR = 0.37, 95% CI 0.15-0.91), and angina (RR = 0.46, 95% CI 0.30-0.71) than that of control group. For trials that included unstable angina patients, CHM led to significantly lower occurrence of total heart events (RR = 0.46, 95% CI 0.32-0.66), myocardial infarction (RR = 0.37, 95% CI 0.26-0.54), and angina (RR = 0.36, 95%CI 0.26-0.51). Likewise, for trials that included stable or unstable angina patients, the rates of myocardial infarction (RR = 0.34, 95% CI 0.17-0.68) and angina (RR = 0.46, 95% CI 0.30-0.70) in CHM group were significantly lower than that in control group. In conclusion, CHM is very likely to be able to improve the survival of angina patients who are already receiving western medicine. PMID:24416066

    Full Text Available The 894G>T polymorphism of the endothelial constitutive nitric oxide synthase gene consists of the substitution of a guanine base by a thymine at the 894th nucleotide of the gene. An association of this polymorphism with acute coronary syndromes has been described, only when in combination with other polymorphisms of this gene. The aim of the present study was to search for an association between this polymorphism and unstable angina in a southern Brazilian population. In a case-control study, 156 patients (group 1 (N = 83: unstable angina, group 2 (N = 73: stable angina were genotyped by PCR and digestion of the product. Univariate analysis demonstrated that the minimal luminal diameter and the degree of stenosis of the culprit lesion differed between groups (P = 0.006 and 0.005, respectively. In addition, the frequencies of the T allele and of the T allele carriers (combined TT and TG genotypes were significantly higher in the group with unstable angina (41.6 vs 28.8%; P = 0.025, Pearson chi-square test, and 73.5 vs 45.2%; P = 0.001, Pearson chi-square test, respectively. Multivariate logistic regression showed that the frequency of the T allele carriers was the only variable with a predictive value for unstable angina, when controlled for the other variables (6.1 (95% CI = 2.55-14.43; P T polymorphism was associated with unstable angina. We suggest that this polymorphism may be a genetic risk factor for unstable angina.

    Tonsillar infection with Streptococcus pyogenes may induce several nonsuppurative autoimmune sequelae. The precise pathogenetic mechanisms behind this clinically well-established association are still unresolved. Using TCR analysis, we sought to identify a link between streptococcal tonsillitis and the T cell-mediated autoimmune response in psoriasis. Three patients with streptococcal-induced psoriasis underwent tonsillectomy. Using size spectratyping and sequencing of TCR beta-chain variable region gene (TCRBV) rearrangements, we compared the TCR usage of psoriatic skin lesions, blood, tonsils, and tonsillar T cells fractionated according to the expression of the skin address in "cutaneous lymphocyte-associated Ag" (CLA). TCRBV-size spectratype analysis of the blood lymphocytes, tonsils, and the CLA-negative tonsillar T cells revealed largely unselected T cell populations. Instead, TCRBV gene families of the psoriatic lesions and skin-homing CLA-positive tonsillar T cells displayed highly restricted spectratypes. Sequencing of TCRBV cDNA identified various clonal TCRBV rearrangements within the psoriatic lesions that indicated Ag-driven T cell expansion. Several of these clonotypes were also detected within the tonsils and, in one of the patients, within the small subset of CLA-positive tonsillar T cells, suggesting that T cells from the same T cell clones were simultaneously present within skin and tonsillar tissue. Because after tonsillectomy psoriasis cleared in all three patients our observations indicate that T cells may connect psoriatic inflammation to streptococcal angina. They suggest that the chronic streptococcal immune stimulus within the tonsils could act as a source for pathogenic T cells in poststreptococcal disorders, and they may help to explain why eliminating this source with tonsillectomy may improve streptococcal-induced sequelae.

    Inflammation has been shown to play an important role in the pathogenesis of unstable angina. CRP has been demonstrated to be a reliable marker of prognosis is unstable angina. The aim of this study was to investigate the prognostic value of CRP in assessing short outcome of unstable angina. Our study is a prospective double blinded one. We measured CRP in 33 consecutive patients admitted for unstable angina at the 24th and 48th hour. The mean age is 60 years (30 to 84 years). There were 22 men and 11 women. 8 patients were included in class I of Braunwald classification, 5 were in class II and 20 in class III. 14 patients presented cardiac events. The CRP mean value was significantly higher among these patients (12 mg/l vs 5 mg/l, p or = 3 mg/l have a higher risk of developing complications (66% vs 13%, p = 0.002). Elevation of CRP predicted poor outcome of intrahospital evolution with a sensitivity of 86%, a specificity 68%, a positive and negative predictive values of 66% and 86%. The CRP in our preliminary study is an independent risk factor of early outcome of unstable angina. In association with clinical scores and other cardiac markers will lead to a better identification of high risk patients.

    In a 49-year-old man with crescendo angina, elevated serum cholesterol level and an old posterior myocardial infarction, selective coronary arteriography showed multiple arteriosclerotic aneurysms of the right coronary artery associated with extensive and severe arteriosclerotic disease of the left coronary artery. The patient's mother and brother have both died of a myocardial infarction. Another brother suffers from angina and has documented arteriosclerotic coronary artery disease. Two sisters suffer from angina as well. The possibility of embolization of distal vessels from a friable clot of the aneurysms as a cause of the patient's infarction is discussed. To the best of our knowledge, this is the tenth patient with nonfistulous arteriosclerotic coronary artery aneurysm diagnosed and documented angiographically ante mortem. Including the present case and reviewing the literature, the prevalence of this condition among nonfistulous coronary aneurysms diagnosed ante mortem is 35 per cent and henceforth cannot be regarded as an incidental autopsy finding in cardiac asymptomatic patients.

    This paper demonstrates the basic properties in the systems most commonly considered for costing treatments in the Danish hospitals. The differences between the traditional charge system, the DRG system and the ABC system are analysed, and difficulties encountered in comparing these systems are discussed. A sample of patients diagnosed with stable angina pectoris (SAP) at Odense University Hospital was used to compare the three systems when costing an entire treatment path, costing single hospitalisations and studying the effects of length of stay. Furthermore, it is illustrated that the main idea behind each system is reflected in how the systems over- or underestimate costs. Implications when managing the hospitals, particularly reimbursement, are discussed.

    Anomalies of the left coronary artery are very rare, with an incidence range between .3% and 1.64%. The diagnosis is generally incidental during coronary angiogram, coronary artery bypass operation, or autopsy. However, sometimes this anomaly is not recognized during CABG operation and can be responsible for the recurrence of angina after CABG operation and even compromise the outcome. We presented a case in which the dual left anterior coronary artery from the right aortic sinus occasionally was shown in a coronary angiogram after CABG operation; the angiogram was performed because of the recurrence of angina.

    In 2013 the European Society of Cardiology (ESC) released new guidelines on the management of stable coronary artery disease. These guidelines update and replace the previous ESC guidelines on the management of stable angina pectoris, issued in 2006. There are several new aspects in the 2013 ESC guidelines compared with the 2006 version. This opinion paper provides an in-depth interpretation of the ESC guidelines with regard to these issues, to help physicians in making evidence-based therapeutic choices in their routine clinical practice. The first new element is the definition of stable coronary artery disease itself, which has now broadened from a 'simple' symptom, angina pectoris, to a more complex disease that can even be asymptomatic. In the first-line setting, the major changes in the new guidelines are the upgrading of calcium channel blockers, the distinction between dihydropyridines and non-dihydropyridine calcium channel blockers, and the presence of important statements regarding the combination of calcium channel blockers with beta-blockers. In the second-line setting, the 2013 ESC guidelines recommend the addition of long-acting nitrates, ivabradine, nicorandil or ranolazine to first-line agents. Trimetazidine may also be considered. However, no clear distinction is made among different second-line drugs, despite different quality of evidence in favour of these agents. For example, the use of ranolazine is supported by strong and recent evidence, while data supporting the use of the traditional agents appear relatively scanty. PMID:27222385

    30 patients with angina decubittus(AD) were studied during hospitalization. These patients were found to have severe coronary artery obstructive lesions and an increase of myocardial oxygen consumption (MOC) before the onset to AD, indicating that AD belongs to the category of effort angina. 18 patients were investigated by continuous hemodynamic mordtoring. Three patients had significant increase in pulmonary artery diastolic pressure (PADP) before the onset. In the other 15 patients, PADP increased slightly in J2 and remained unchanged in 3 cases before the onset. Left ventriculography showed ejection fraction (EF))45% in 25 of the 27 patients. These results indicate that left ventricular (LV) systolic dysfunction is not a major factor in the pathogenesis of AD. The patients with LVEDP>12 mmHg constituted 60% of 25 patients with EF)45%, suggesting that these patients had obvious LV diastolic dysfunction, which may he the major factor in the pathogenesis of AD. According to the results of our treatment, Beta blockers may be used as the major form of treatment in the patients with AD.

    Full Text Available Objective. To systematically collect evidence and evaluate the effects of Danhong injection (DHI for unstable angina (UA. Methods. A comprehensive search was conducted in seven electronic databases up to January 2015. The methodological and reporting quality of included studies was assessed by using AMSTAR and PRISMA. Result. Five articles were included. The conclusions suggest that DHI plus conventional medicine treatment was effective for UA pectoris treatment, could alleviate symptoms of angina and ameliorate electrocardiograms. Flaws of the original studies and systematic reviews weaken the strength of evidence. Limitations of the methodology quality include performing an incomprehensive literature search, lacking detailed characteristics, ignoring clinical heterogeneity, and not assessing publication bias and other forms of bias. The flaws of reporting systematic reviews included the following: not providing a structured summary, no standardized search strategy. For the pooled findings, researchers took statistical heterogeneity into consideration, but clinical and methodology heterogeneity were ignored. Conclusion. DHI plus conventional medicine treatment generally appears to be effective for UA treatment. However, the evidence is not hard enough due to methodological flaws in original clinical trials and systematic reviews. Furthermore, rigorous designed randomized controlled trials are also needed. The methodology and reporting quality of systematic reviews should be improved.

    2002-04-01

    Full Text Available El presente trabajo corresponde una revisión bibliográfica de los estudios clínicos realizados en síndromes anginosos refractarios al tratamiento convencional, utilizando como tratamiento el bloqueo de ganglio estrellado. Se realizó una búsqueda de literatura publicada entre los años 1.900 al 2.000 en las bases de datos MDConsult, Medline y ProQuest. A su vez se revisaron las publicaciones en la Biblioteca del Hospital Rafael Ángel Calderón Guardia y en la Biblioteca del BINASSS (Biblioteca Nacional de Salud del Seguro Social. De acuerdo a los estudios analizados el bloqueo de ganglio estrellado se describe como posibilidad terapéutica para el control de dolor de la angina de pecho refractaria . La descripción clásica de la inervación cardíaca consiste en tres nervios simpáticos mayores originados de los ganglios cervicales superior, medio e inferior. Esta inervación simpática en conjunto con diversos nervios parasimpáticos, se describen como el plexo cardíaco. En contraste Jane et. al. (1986 en un estudio anatómico de 23 cadáveres describe que la inervación cardiopulmonar en el hombre se origina en el ganglio estrellado y las mitades caudales de las cadenas simpáticas cervicales junto con nervios que se originan del nervio recurrente laríngeo o del vago. De estas estructuras derivan los dos plexos cardiopulmonares. De estos plexos derivan tres nervios cardíacos mayores que se proyectan hacia el corazón. Se estima que determinado porcentaje de los pacientes diagnosticados con angina inestable progresará a desarrollar una angina refractaria al tratamiento. El bloqueo de ganglio estrellado podría ser un nuevo método terapéutico para controlar el dolor de dicha condición. Sin embargo se necesitan estudios clínicos randomizados a doble ciego para obtener resultados concluyentes.

    Full Text Available Chinese herbal medicine (CHM has been widely used as an adjunct to western medicine in treating angina in China. We carried out this systematic review to evaluate the effectiveness of CHM on top of western medicine for angina. This meta-analysis included 46 randomized control trials with 4212 patients. For trials that included stable angina patients, the CHM group had significant lower incidence of total heart events (relative risk (RR=0.50, 95% confidence interval (CI 0.33–0.78, myocardial infarction (RR=0.32, 95% CI 0.14–0.72, heart failure (RR=0.37, 95% CI 0.15–0.91, and angina (RR=0.46, 95% CI 0.30–0.71 than that of control group. For trials that included unstable angina patients, CHM led to significantly lower occurrence of total heart events (RR=0.46, 95% CI 0.32–0.66, myocardial infarction (RR=0.37, 95% CI 0.26–0.54, and angina (RR=0.36, 95%CI 0.26–0.51. Likewise, for trials that included stable or unstable angina patients, the rates of myocardial infarction (RR=0.34, 95% CI 0.17–0.68 and angina (RR=0.46, 95% CI 0.30–0.70 in CHM group were significantly lower than that in control group. In conclusion, CHM is very likely to be able to improve the survival of angina patients who are already receiving western medicine.

  2. Nitrate-Induced Headache in Patients with Stable Angina Pectoris: Beneficial Effect of Starting on a Low Dosage.

    1996-12-01

    BACKGROUND: Nitrates, although important for the management of angina pectoris, cause significant headache in many patients. METHODS: In a randomized, double-blind crossover study, 89 patients with stable angina pectoris were used to compare two different dosage strategies of isosorbide-5-mononitrate (5-ISMN). Patients were randomized to either 60 mg 5-ISMN once daily (o.d.) for 2 weeks or 30 mg 5-ISMN o.d. for 1 week followed by 60 mg 5-ISMN o.d. for 1 week. A 2-week placebo wash-out ensued, after which the alternative treatment was given. We assessed the occurrence of angina pectoris and headache by diary cards while taking into account the numbers of isosorbide dinitrate sublingual puffs and paracetamole tables required. Data were assessed for carryover and time effects. RESULTS: The two dosage regimens were equally efficient for the relief of angina pectoris without development of tolerance. Thirty percent of the patients never experienced headache from the given dosages. The remainder showed a highly significant time-effect: The total numbers of headache attacks in the 1st period of active treatment were 2,380 vs 1,400 attacks is the 2nd period (p < 0.003), yet significantly fewer patients had headaches on low dosages than high ones (45 vs 57, p < 0.02). CONCLUSIONS: Starting on a low dosage was associated with reduced frequency and severity of headache and did not notably influence the beneficial effect of nitrates on angina pectoris. One in three patients never experienced headache from the given dosages. The overall number of headache attacks in the 1st period of active treatment was significantly higher than that of the 2nd period, irrespective of the dosages given. PMID:11862241

    2004-03-01

    This paper demonstrates the basic properties in the systems most commonly considered for costing treatments in the Danish hospitals. The differences between the traditional charge system, the DRG system and the ABC system are analysed, and difficulties encountered in comparing these systems are discussed. A sample of patients diagnosed with stable angina pectoris (SAP) at Odense University Hospital was used to compare the three systems when costing an entire treatment path, costing single hospitalisations and studying the effects of length of stay. Furthermore, it is illustrated that the main idea behind each system is reflected in how the systems over- or underestimate costs. Implications when managing the hospitals, particularly reimbursement, are discussed. PMID:15036817

    Full Text Available In unstable angina (USA patients, immunological responses contributing to inflammation play a vital role in plaque rupture and thrombosis causing stroke. In the present study an attempt is made to estimate the levels of adenosine deaminase activity, an immunoenzyme marker and C-reactive protein, a marker of inflammation in USA patients. 45 patients presenting USA and 50 age and sex matched healthy controls were included in the study. Serum ADA activity was measured spectrophotometrically at 630nm and serum C-reactive protein was detected using Avitex CRP kit, which is a rapid latex agglutination test. The Mean ADA levels were 41.15 ± 11.04 in patients and 20.71±5.63 in controls and 66.6% of patients and none of the controls were positive to CRP. The present study observed the importance of ADA as a serum marker in addition to CRP for assessing the immune response in USA patients.

    Objective. To determine whether serum vascular endothelial growth factor(VEGF)concentrations are altered in several kinds of coronary heart disease patients. Materials and methods. Using a VEGF enzyme-linked immunosorbent assay(ELISA), serum VEGF concentra tions were determined in antecubital venous blood of 16 patients with stable angina pectoris(SAP), 16 with unstable angina pectoris(UAP) and 16 with acute myocardial infarction(AMI) before and after thrombolytic therapy, and of 16 age and sex-matched healthy volunteers who used as controls. Results. The concentrations of serum VEGF in patients with SAP(98.60 ± 26.99pg/ml) and UAP (103.61 ± 24.89pg/ml) tended to be higher than those in control subjects(80.44 ± 24.57pg/ml), but the differences did not reach statistical significance (P > 0.05 for each). Before throm bolytic therapy, the concentrations of serum VEGF in patients with AMI (285.92 ± 125.15pg/ml) were significantly higher than those in patients with SAP, UAP or control subjects ( P < 0.01 ,respectively), and correlated with synchronous serum creatine kinase (CK) and its MB isoenzyme (CK-MB) contents(r=0.866, P < 0.001 and r =0.948,P < 0.001;respectively). Three hours after thrombolysis, the concentrations of VEGF had fallen to 111.57 ± 31.29pg/ml ( P <0.01 vs. before thrombolytic therapy and P< 0.05 vs .control subjects). Conclusion. The present study shows that serum concentrations of VEGF in patients with AMI are markedly ele vated and that increased serum VEGF levels may be one of the most sensitive indexes in diagnosing AMI and judging reperfusion.

    Objective. To investigate the effect of left veraricular diastolic dysfunction on the pathogenesis of angina decubitus (AD).Methods. The study population consisted of three groups: 20 individuals without cardiovascular disease were studied as group Ⅰ . Group Ⅱ included 20 patents with coronary artery disease and without AD. Thirty-one patients with AD and ejection fraction(EF) > 50% were studied as group Ⅲ. Group Ⅱ and Ⅲ were matched for age, EF and extent of coronary artery disease.Results. Left ventricnlography (LVG) showed that left ventricnlar (LV) first 1/3 filling fraction (1/3FF) was significantly lower in group Ⅲ than in group Ⅱ and Ⅰ (both P <0.001),but LV late 1/3 FF was much higher in group Ⅲ than in group Ⅱ and Ⅰ (P < 0.05, P < 0.01). Left ventricular end-diastohc presstrre(LVEDP) was markedly inereased before and after LVGin group Ⅱ and Ⅲ as compared with group Ⅰ (beth P<0.05, beth P<0.001). The difference of LVEDP caused by left atrial contraction (left atrial contraction pressure difference, LACPD) before and after LVG was much higher in group Ⅲ than in group Ⅰ ( P < 0.01, P < 0.001). Howevere, there were significant differences in LVEDP and in LACPD between before and after LVG only in group Ⅲ (both P < 0.01).Conclusion. The patients with AD have LV diastolic dysfunction, which may be closely related to the pathogen-esis of angina decubitus.

    The significance of silent myocardial ischemia detected by dipyridamole perfusion scintigraphy was evaluated in 80 patients with stable angina and reversible defects (RD) but no infarction. The patients consisted of 26 patients with silent RD and 54 patients with painful RD. There was no significant difference in the incidence of coronary risk factors between the two groups, except for hyperlipidemia which was less frequently observed in patients with silent RD than in those with painful RD (8% vs 41%), Coronary angiography revealed a higher prevalence of insignificant lesions or single vessel disease in patients with silent RD than in those with painful RD (73% vs 39%). Dipyridamole perfusion scintigraphy revealed a lower degree of RD in patients with silent RD than in those with painful RD (4.4{+-}3.3 vs 9.0{+-}4.1 segments), though there was no significant difference in the localization of RD between these two groups. Treadmill stress testing revealed a lower incidence of chest pain in patients with silent RD than in those with painful RD (26% vs 65%), despite the mean exercise-duration being significantly longer in the former than in the latter (5.5{+-}1.7 vs 3.9{+-}11.7 min). Although initial percutaneous transluminal coronary angioplasty (PTCA) and/or coronary artery bypass grafting (CABG) were less frequently performed in patients with silent RD than in those with painful RD (12% vs 31%), there was no significant difference in the cardiac event rate during the mean follow-up period of 24{+-}14 months between the two groups. Patients with stable angina and silent RD on dipyridamole perfusion scintigraphy may have less extensive coronary lesions and smaller amounts of ischemic myocardium than patients with painful RD. Dipyridamole perfusion scintigraphy is useful for detecting and evaluating silent myocardial ischemia, even in those patients who cannot exercise adequately. (J.P.N.).

Mildronate provides additional benefits for patients with IHD with stable burden angina, when they do not reach desired effect with the prescribed AAT.

  15. Alterations in left ventricular function during therapy of unstable angina pectoris: relationship to clinical outcome

    International Nuclear Information System (INIS)

    We studied 30 consecutive patients with unstable angina during pain-free intervals with gated blood pool scintigraphy. The initial study was performed within 18 hours of admission to the coronary care unit. A second study was performed near the time of hospital discharge, after stabilization with medical therapy. Three months thereafter patients were categorized according to their worst anginal status following hospital discharge. Fifteen patients were New York Heart Association functional class I or II (group A); 15 patients were in functional class III or IV (group B). Left ventricular ejection fraction was similar at the time of initial study (55.9 +/- 2.18% and 56.0 +/- 3.55% for groups A and B respectively). At the time of hospital discharge the ejection fraction had risen to 60.3 +/- 1.85% (p less than 0.01) in group A and in group B it had fallen to 48.1 +/- 3.4% (p less than 0.005). End-systolic volume index in group B rose from 37 ml/m2 +/- 6.1 to 43 +/- 6.2 ml/m2 (p less than 0.005) at the time of the follow-up study. There were no significant intergroup patients during the two scintigraphic examinations. Eleven group B patients subsequently underwent coronary artery bypass surgery. A significant increase in ejection fraction and a significant decrease in end-systolic volume index were noted when these patients were restudied an average of 3.2 months after surgery. This study suggests that changes in left ventricular function during the course of unstable angina pectoris are common and may be detected by serial gated blood pool scintigraphy

  16. Persulfate activation during exertion of total oxidant demand.

    Teel, Amy L; Elloy, Farah C; Watts, Richard J

    2016-09-01

    Total oxidant demand (TOD) is a parameter that is often measured during in situ chemical oxidation (ISCO) treatability studies. The importance of TOD is based on the concept that the oxidant demand created by soil organic matter and other reduced species must be overcome before contaminant oxidation can proceed. TOD testing was originally designed for permanganate ISCO, but has also recently been applied to activated persulfate ISCO. Recent studies have documented that phenoxides activate persulfate; because soil organic matter is rich in phenolic moieties, it may activate persulfate rather than simply exerting TOD. Therefore, the generation of reactive oxygen species was investigated in three soil horizons of varied soil organic carbon content over 5-day TOD testing. Hydroxyl radical may have been generated during TOD exertion, but was likely scavenged by soil organic matter. A high flux of reductants + nucleophiles (e.g. alkyl radicals + superoxide) was generated as TOD was exerted, resulting in the rapid destruction of the probe compound hexachloroethane and the common groundwater contaminant trichloroethylene (TCE). The results of this research document that, unlike permanganate TOD, contaminant destruction does occur as TOD is exerted in persulfate ISCO systems and is promoted by the activation of persulfate by soil organic matter. Future treatability studies for persulfate ISCO should consider contaminant destruction as TOD is exerted, and the potential for persulfate activation by soil organic matter. PMID:27269993

    Unfractionated heparin (UFH and low-molecularweight heparins (LMWHs are widely used in curative and preventive treatments of thromboembolic disorders. The aim of the study was to investigate factors associated with the choice of these types of heparin to treat patients with unstable angina under real conditions of hospital use. A cross-sectional study was performed in a private general hospital in Belo Horizonte, Brazil, from January 1st to December 31th, 2001. Data were collected from the hospital electronic database. Inpatients with angina who received enoxaparin or UFH were included in the survey. Data for 555 patients were recorded, including 401 treated with enoxaparin and 154 with UFH. Univariate analysis showed that male and elderly people predominated in both groups, with no statistical difference in the proportions (p>0.05. Multivariate analysis showed 4 factors associated with the use of enoxaparin: cardiac revascularization surgery (OR=0.434, arrhythmias (OR=9.343, risk factors for coronary artery disease (OR=1.333 and private health insurance (OR=0.297. Thus, clinical and organizational factors were associated with the type of heparin used by patients with unstable angina at this hospital. Further drug utilization studies are necessary to expand and improve the data available on the use of heparins in the hospital setting. Keywords: Hospital pharmacy/assessment.

    OBJECTIVE—To assess prospectively the prognostic value of soluble cellular adhesion molecules (CAMs) in patients with unstable angina and non-Q wave myocardial infarction and to compare their prognostic accuracy with that of C reactive protein (CRP).
DESIGN AND SETTING—Prospective observational study of patients presenting acutely with unstable angina and non-Q wave myocardial infarction to a single south Dublin hospital.
METHODS—Patients with Braunwald IIIA unstable angina and non-Q wave myocardial infarction had serum samples taken at presentation before initiation of antithrombotic treatment and were followed for six months. The primary end point was the occurrence of major adverse cardiovascular events (recurrent unstable angina, non-fatal myocardial infarction, and cardiovascular death) at six months. Concentrations of soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble endothelial selectin, and soluble platelet selectin were measured using an enzyme linked immunosorbent assay technique. CRP was measured with an immunophelometric assay.
RESULTS—91 patients (73 men and 18 women, mean (SD) age 61 (11) years) were studied; 27 patients (30%) had major adverse cardiac events during the six months of follow up. Concentration of CRP were significantly raised in patients who had an ischaemic event (mean (SEM) 11.5 (6.4) mg/l v 5.4 (2.5) mg/l, p  3 mg/l and sVCAM-1 > 780 ng/ml for predicting future events was > 90%. There was no difference in concentrations of sICAM-1, soluble endothelin selectin, or soluble platelet selectin between event and non-event groups.
CONCLUSION—Raised concentrations of sVCAM-1 and CRP are predictive of an increased risk of major adverse cardiovascular events six months after presentation with unstable angina and non-Q wave myocardial infarction. These findings suggest that the intensity of the vascular inflammatory process at the time of

    Coronary heart disease (CHD) is one of the leading causes of death worldwide. Moreover, angina pectoris is one of the most important types of CHD. Therefore, prevention and effective treatment of angina pectoris is of utmost importance in both China and western countries. However, undesirable effects of antianginal therapy do influence treatment adherence to a certain extent. Therefore, it's not surprising that, complementary and alternative medicine (CAM), including Chinese medicine (CM), are widely welcomed among patients with CHD, hoping that it might complement western medicine. In our previous studies, blood stasis syndrome (BSS) (Xueyu Zheng) was the main syndrome (Zheng-hou) of angina pectoris. Currently, China Food and Drug Administration authoritatively recommended more than 200 Chinese patent medicines (CPMs) as complementary or adjunctive therapies for symptom management and enhancing quality of life along with mainstream care on angina pectoris management in mainland China. This paper reviewed 4 kinds of most frequently-used CPMs by promoting blood circulation and removing blood stasis in the treatment of angina pectoris. It aims to evaluate the current evidence of CPMs in combination therapy for angina pectoris. This review indicated that CPMs as adjunctive treatment to routine antianginal therapy play an active role in reducing the incidence of primary endpoint events, decreasing anginal attack rate, and improving electrocardiogram. Additionally, CPMs have been proven relatively safe. Further rigorously designed clinical trials should be conducted to confirm the results. PMID:25360837

    Evidence-based guidelines for the use of aspirin in secondary prevention of cardiovascular disease events are well established. Despite this, the prevalence of aspirin use for secondary prevention is suboptimal. The study aimed to determine the prevalence of aspirin use for secondary prevention of cardiovascular disease events when it is dispensed as a prescription, as is performed in the Veterans Affairs (VA) managed care system. VA patients who had undergone major surgery and experienced a postoperative myocardial infarction (MI) or unstable angina between the years 2005 and 2009 were identified from administrative databases. VA pharmacy records were used to determine whether a prescription for aspirin was filled after the postoperative MI or unstable angina. Multivariable logistic regression models estimated odd ratios of filling aspirin prescriptions for the predictors of interest. Of the 321,131 men and women veterans who underwent major surgery, 7,700 experienced a postoperative MI or unstable angina. Among those 7,700, 47% filled an aspirin prescription. Only 59% of veterans with no co-pay filled an aspirin prescription. Aspirin fills were more common in younger veterans, Blacks, Hispanics, males, hypertensive veterans, mentally ill patients, those with no co-pay and those prescribed antiplatelets/anticoagulants in addition to aspirin postoperatively. These findings suggest that the impact of dispensing aspirin as a prescription may not be significant in increasing the appropriate use of aspirin for secondary prevention. PMID:26351774

    2007-01-01

    The clinical presentation of Ludwig's angina consists in a severe expanding cellulitis causing swelling of the floor of the mouth, tongue and submandibular region, thus resulting in a possible obstruction of the airway and in a rapid progress in deep neck soft tissue infection and mediastinitis with potentially fatal consequences. Frequently, submandibular cellulitis develops from an acute infection spreading from the lower molar teeth. Mandibular fractures, traumatic laceration of the floor of the mouth, and peritonsillar abscesses are other concomitant clinical features. A case of Ludwig's angina associated with a large erupted odontoma and with a deeply impacted third molar displaced to the border of the mandible is described. The patient was affected by enlargement of submandibular space, marked face swelling causing an evident face deformity, tenderness and redness of the neck and limited movement of the neck and mouth. In the past, Ludwig's angina was frequently fatal, however aggressive surgical and medical therapy have significantly reduced the mortality rate. The reported case can be considered as important, not only because of the rarity of the odontoma eruption in the oral cavity, but mainly for the extent of the clinical manifestation of a lesion usually described in literature as asymptomatic.

    Full Text Available Contamination of crops used for food and feed production with Fusarium mycotoxins, such as deoxynivalenol (DON, raise important health and economic issues all along the food chain. Acute exposure to high DON concentrations can alter the intestinal barrier, while chronic exposure to lower doses may exert more subtle effects on signal transduction pathways, leading to disturbances in cellular homeostasis. Using real-time cellular impedance measurements, we studied the effects exerted in vitro by low concentrations of DON (0.37–1.50 μM, relevant for mycotoxin-contaminated food, on the proliferation of undifferentiated Caco-2 cells presenting a tumorigenic phenotype. A 1.5 μM concentration of DON maintained cell adherence of non-proliferating Caco-2 cells, whilst arresting the growth of actively proliferating cells compared with control Caco-2 cells in vitro. At 0.37 μM, DON enhanced Caco-2 cell metabolism, thereby triggering a moderate increase in cell proliferation. The results of the current study suggested that low concentrations of DON commonly detected in food may either limit or sustain the proliferation of colon cancer cells, depending on their proliferation status and on DON concentration. Soluble factors released by Lactobacillus strains can partially counteract the inhibitory action of DON on actively proliferating colon cancer cells. The study also emphasized that real-time cellular impedance measurements were a valuable tool for investigating the dynamics of cellular responses to xenobiotics.

    Activity-related dyspnoea is often the most distressing symptom experienced by patients with chronic obstructive pulmonary disease (COPD) and can persist despite comprehensive medical management. It is now clear that dyspnoea during physical activity occurs across the spectrum of disease severity, even in those with mild airway obstruction. Our understanding of the nature and source of dyspnoea is incomplete, but current aetiological concepts emphasise the importance of increased central neural drive to breathe in the setting of a reduced ability of the respiratory system to appropriately respond. Since dyspnoea is provoked or aggravated by physical activity, its concurrent measurement during standardised laboratory exercise testing is clearly important. Combining measurement of perceptual and physiological responses during exercise can provide valuable insights into symptom severity and its pathophysiological underpinnings. This review summarises the abnormal physiological responses to exercise in COPD, as these form the basis for modern constructs of the neurobiology of exertional dyspnoea. The main objectives are: 1) to examine the role of cardiopulmonary exercise testing (CPET) in uncovering the physiological mechanisms of exertional dyspnoea in patients with mild-to-moderate COPD; 2) to examine the escalating negative sensory consequences of progressive respiratory impairment with disease advancement; and 3) to build a physiological rationale for individualised treatment optimisation based on CPET.

    2001-12-01

    Full Text Available Abstract Background Takayasu's arteritis is a chronic systemic inflammatory disease that usually affects the aorta, its primary branches and occasionally the pulmonary and coronary arteries. Female gender in reproductive age and Asian origin are known factors associated with higher disease prevalence. The clinical manifestations vary considerably and are typically caused by limb or organ ischemia illness and fever. The estimated incidence rate in the western world is 2.6 cases per million persons per year. Occasionally, exertional dyspnea can be the sole primary clinical manifestation of Takayasu's arteritis. Case presentation We report the case of a 57-year-old woman who was referred to our institution with increasing exertional dyspnea caused by pulmonary artery involvement in Takayasu's arteritis. In a review of the literature we discuss demographic data, clinical and radiographic findings and available therapeutic options. Conclusions Dyspnea due to pulmonary artery involvement can be the initial symptom of Takayasu's arteritis. Simple clinical tests, including a complete pulse-status and blood pressure measuring at both arms can lead to the right diagnosis and should always be done beyond the auscultation of the heart and lungs in patients with dyspnea.

    Chronic inflammatory mediators exert pleiotropic effects in the development of cancer. On the one hand, inflammation favors carcinogenesis, malignant transformation, tumor growth, invasion, and metastatic spread; on the other hand inflammation can stimulate immune effector mechanisms that might limit tumor growth. The link between cancer and inflammation depends on intrinsic and extrinsic pathways. Both pathways result in the activation of transcription factors such as NF-κB, STAT-3, and HIF-...

  2. Fluoxetine exerts age-dependent effects on behavior and amygdala neuroplasticity in the rat.

    Full Text Available The selective serotonin reuptake inhibitor (SSRI Prozac® (fluoxetine is the only registered antidepressant to treat depression in children and adolescents. Yet, while the safety of SSRIs has been well established in adults, serotonin exerts neurotrophic actions in the developing brain and thereby may have harmful effects in adolescents. Here we treated adolescent and adult rats chronically with fluoxetine (12 mg/kg at postnatal day (PND 25 to 46 and from PND 67 to 88, respectively, and tested the animals 7-14 days after the last injection when (norfluoxetine in blood plasma had been washed out, as determined by HPLC. Plasma (norfluoxetine levels were also measured 5 hrs after the last fluoxetine injection, and matched clinical levels. Adolescent rats displayed increased behavioral despair in the forced swim test, which was not seen in adult fluoxetine treated rats. In addition, beneficial effects of fluoxetine on wakefulness as measured by electroencephalography in adults was not seen in adolescent rats, and age-dependent effects on the acoustic startle response and prepulse inhibition were observed. On the other hand, adolescent rats showed resilience to the anorexic effects of fluoxetine. Exploratory behavior in the open field test was not affected by fluoxetine treatment, but anxiety levels in the elevated plus maze test were increased in both adolescent and adult fluoxetine treated rats. Finally, in the amygdala, but not the dorsal raphe nucleus and medial prefrontal cortex, the number of PSA-NCAM (marker for synaptic remodeling immunoreactive neurons was increased in adolescent rats, and decreased in adult rats, as a consequence of chronic fluoxetine treatment. No fluoxetine-induced changes in 5-HT(1A receptor immunoreactivity were observed. In conclusion, we show that fluoxetine exerts both harmful and beneficial age-dependent effects on depressive behavior, body weight and wakefulness, which may relate, in part, to differential

    Hypotension, bradycardia, and contrast induced chest pain are potential complications of cardiac catheterization and coronary angiography. Catheter-induced coronary spasm has been occasionally demonstrated, but its relationship to spontaneous coronary spasm is unclear. We describe a 64-year-old female who underwent coronary artery bypass surgery in 1998 on the basis of an angiographic diagnosis of severe left main disease, who recently presented with increasingly frequent typical angina. Repeat coronary angiography was immediately complicated by severe chest pain, hypotension, and bradycardia but demonstrated only mild disease of the left main artery and entire coronary tree with complete occlusion of her prior grafts. This reaction was almost identical to that observed during her original coronary angiogram. We now believe her original angiogram was complicated by severe catheter-induced left main spasm, with the accompanying contrast reaction attributed to left main disease, and the occlusion of coronary grafts explained by the absence of significant left main disease. The combination of these symptoms has not been documented in the literature. In this instance, these manifestations erroneously led to coronary bypass surgery. It is unknown whether routine, systematic injection of intracoronary nitroglycerin prior to angiography might blunt the severity of such reactions. PMID:26981290

  4. Nitric Oxide Synthetic Pathway in Patients with Microvascular Angina and Its Relations with Oxidative Stress

    Full Text Available A decreased nitric oxide (NO bioavailability and an increased oxidative stress play a pivotal role in different cardiovascular pathologies. As red blood cells (RBCs participate in NO formation in the bloodstream, the aim of this study was to outline the metabolic profile of L-arginine (Arg/NO pathway and of oxidative stress status in RBCs and in plasma of patients with microvascular angina (MVA, investigating similarities and differences with respect to coronary artery disease (CAD patients or healthy controls (Ctrl. Analytes involved in Arg/NO pathway and the ratio of oxidized and reduced forms of glutathione were measured by LC-MS/MS. The arginase and the NO synthase (NOS expression were evaluated by immunofluorescence staining. RBCs from MVA patients show increased levels of NO synthesis inhibitors, parallel to that found in plasma, and a reduction of NO synthase expression. When summary scores were computed, both patient groups were associated with a positive oxidative score and a negative NO score, with the CAD group located in a more extreme position with respect to Ctrl. This finding points out to an impairment of the capacity of RBCs to produce NO in a pathological condition characterized mostly by alterations at the microvascular bed with no significant coronary stenosis.

    AIM: To evaluate the association between gastroesophageal reflux diseases (GERD) and coronary heart diseases. METHODS: One thousand nine hundred and seventy consecutive patients who attended our hospital were enrolled. All of the patients who first attend our hospital were asked to respond to the F-scale questionnaire regardless of their chief complaints. All patients had a careful history taken, and resting echocardiography (ECG) was performed by physicians if the diagnostic necessity arose. Patients with ECG signs of coronary artery ischemia were defined as Stsegment depression based on the Minnesota code. RESULTS: Among 712 patients (36%) with GERD, ECG was performed in 171 (24%), and ischemic changes were detected in eight (5%). Four (50%) of these patients with abnormal findings upon ECG had no chest symptoms such as chest pain, chest oppression, or palpitations. These patients (0.6%; 4/712) were thought to have non-GERD heartburn, which may be related to ischemic heart disease. Of 281 patients who underwent ECG and did not have GERD symptoms, 20 (7%) had abnormal findings upon ECG. In patients with GERD symptoms and ECG signs of coronary artery ischemia, the prevalence of linked angina was considered to be 0.4% (8/1970 patients). CONCLUSION: The present study suggested that ischemic heart disease might be found although apatient was referred to the hospital with a complaint of GERD symptoms. Physicians have to be concerned about missing clinically important coronary artery disease while evaluating patients for GERD symptoms.

    Increasing evidence has suggested that microRNA (miRNA) may play a role in the pathogenesis of cardiovascular disease, which has led to a greater understanding of the complex pathophysiological processes underlying unstable angina (UA). The present study aimed to investigate changes in the miRNA expression profiles of patients with UA using gene-chip analysis, in order to further elucidate the pathogenesis of UA. Total RNA was extracted and purified from plasma samples collected from patients with UA and healthy controls. The samples underwent microarray analysis using an Exiqon miRCURY LNA™ microRNA Array. Differentially expressed miRNAs were identified by volcano plot filtering, and were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). In addition, functional annotation of the differentially expressed miRNAs involved gene ontology analyses. Among the 212 miRNAs differentially expressed between the two groups, 82 were upregulated and 130 were downregulated. Notably, the results of the RT-qPCR were consistent with the gene-chip results. The miRNAs identified in the present study may be potential novel biomarkers for the prevention and early diagnosis of UA. Furthermore, the results of the present study suggested that UA occurs as a result of complex and dynamic processes regulated by numerous factors, including multiple miRNAs.

    Full Text Available Patients with Glanzmann thrombasthenia fail to form large platelet thrombi due to mutations that affect the biosynthesis and/or function of the αIIbβ3 integrin. The result is a moderate to severe bleeding syndrome. We now report unusual vascular behaviour in a 55-year-old woman with classic type I disease (with no platelet αIIbβ3 expression and a homozygous ITGA2B missense mutation (E324K affecting the terminal β-propeller domain of αIIb. While exhibiting classic bleeding symptoms as a child, in later life this woman first developed deep vein thrombosis after a long air flight then showed vascular problems characteristic of Raynaud’s phenomenon, and finally this year she presented with chest pains suggestive of coronary heart disease. Yet while coronary angiography first showed a stenosis, this was not seen on a second examination when she was diagnosed with coronary spastic angina and Prinzmetal phenomenon. It is significant that the absence of platelet aggregation with physiologic agonists had not prevented any of the above cardiovascular or vascular diseases.

  12. Unstable angina and non-ST-segment myocardial infarction: an evidence-based approach to management.

    Kou, Victoria; Nassisi, Denise

    2006-01-01

    Unstable angina (UA) and non-ST-segment elevation myocardial infarction (NSTEMI) represent two common, closely related acute coronary syndromes with potentially high morbidity and mortality. Integration of information from the history, physical exam, electrocardiogram, and cardiac biomarkers is used to formulate both the diagnosis of UA/NSTEMI and the overall assessment of patient prognosis and risk. Early diagnosis and risk stratification of patients with UA/NSTEMI enable the physician to initiate timely, appropriate treatment. (There is strong clinical evidence supporting the tailoring of specific therapies to the risk profile of the patient.) In recent years, powerful new medical and invasive therapies have been developed. Pharmaceutical agents for UA/NSTEMI may be broadly grouped into one of three categories: anti-ischemic, anti-platelet, and anti-thrombotic agents. Standard therapy for UA/NSTEMI has commonly included oxygen, aspirin, nitrates, morphine, beta-blockers and heparin. Potent new anti-platelet agents, including inhibitors of platelet adenosine diphosphate and glycoprotein IIb/IIIa receptors, play important, expanding roles in the management of these syndromes. Low-molecular-weight heparins have been shown to be an effective alternative to unfractionated heparin in their treatment. Major advances in invasive techniques and devices over the last decade include revascularization with percutaneous coronary intervention and drug-eluting intracoronary stents. Strong interest exists in studying the potential benefits and risks associated with an early invasive therapeutic strategy rather than an aggressive medical regimen for patients with UA/NSTEMI. As new treatments are rapidly added to our growing arsenal of management options, clinicians are constantly challenged with incorporating complex new information and guidelines into their practices in a timely fashion. To assist clinicians with this challenge, this article will review the evidence to support

  13. Correlation between Timi Risk Score and Clinical Outcome in Patients with Unstable Angina Pectoris

    Full Text Available Given Taking that the TIMI score is a major predictor of MACE, this study aimed to determine the value of the TIMI risk score in predicting poor outcomes (death, myocardial infarction, recurrent pain in patients presenting with unstable angina pectoris in short-term observation. A total of 107 patients with APns were examined at the Clinical Centre Kragujevac and were included in the investigation. The TIMI score was determined on the first day of hospitalization. During hospitalization, the following factors were also observed: troponin, ECG evolution, further therapy (pharmacologic therapy and/or emergency PCI or CABG, age, hypertension and hyperlipidaemia. The low-risk group (TIMI 0 - 2 included 30.8% of patients, whereas 47.6% of patients were in the intermediate-risk group (TIMI 3 - 4, and 21.5% of patients were in the high-risk group (TIMI 5 - 7. Good outcomes (without adverse event and poor outcomes (death, myocardial infarction, and recurring chest pain were dependent on the TIMI risk score. The increase in TIMI risk score per one unit increased the risk of a poor outcome by 54%. Troponin and TIMI risk score were positively correlated. Our results suggest that the TIMI risk score may be a reliable predictor of a poor outcome (MACE during the short-term observation of patients with APns. Moreover, patients identified as high-risk benefit from early invasive PCI, enoxaparin and Gp IIb/IIIa inhibitors. Th us, routine use of the TIMI risk score at admission may reduce the number of patients not recognized as high-risk.

    Background Many patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China. Methods Between March 2001 and October 2004, enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.2%), non-ST segment elevation myocardial infarction (239, 16.7%) and unstable angina (532, 37.1%). The demographic distribution, medical history and clinical data were collected to investigate the predictive factors of RA by Logistic regression.Results During hospitalization 275 (19.2%) patients were documented with RA including unstable angina (53.2%), non-ST segment elevation myocardial infarction (27.5%), ST segment elevation myocardial infarction (19.3%). A comorbidity of dyslipidemia, prior angina, percutaneous coronary Intervention (PCI) within 6 months was more common in patients with RA, P<0.05. In the patients with RA, a significantly higher proportion of patients with acute pulmonary edema was observed, 23 (8.4%) versus 43 (3.7%), P=0.001. Acute renal failure was present in 8 (2.9%) of patients with RA versus 19 (1.6%) of patients without RA,P=0.165. Hemorrhagic events were present in 6 (2.2%) of patients with RA versus 8 (0.7%) of patients without RA, ventricular tachycardia/ ventricular fibrillation events in 12 patients (4.3%) versus 22 patients (1.9%), congestive heart failure in 69 patients (25.0%) versus 94 patients (8.1%), myocardial re-infarction in 28 patients (10.1%) versus 15 patients (1.3%), P<0.05, respectively. A lower proportion of patients with RA underwent in-hospital PCI, 687 (59.3%) versus 114 (41.5%), P=0.000. A higher proportion of patients with RA received heparin, 260 (94.5%) versus 1035 (89.4%), P=0.006; and beta-blockers 176(64.0%) versus 864 (74

    Chronic obstructive pulmonary disease (COPD) is a common disease with high global morbidity and mortality. COPD is characterized by poorly reversible airway obstruction, which is confirmed by spirometry, and includes obstruction of the small airways (chronic obstructive bronchiolitis) and emphysema, which lead to air trapping and shortness of breath in response to physical exertion. The most common risk factor for the development of COPD is cigarette smoking, but other environmental factors, such as exposure to indoor air pollutants - especially in developing countries - might influence COPD risk. Not all smokers develop COPD and the reasons for disease susceptibility in these individuals have not been fully elucidated. Although the mechanisms underlying COPD remain poorly understood, the disease is associated with chronic inflammation that is usually corticosteroid resistant. In addition, COPD involves accelerated ageing of the lungs and an abnormal repair mechanism that might be driven by oxidative stress. Acute exacerbations, which are mainly triggered by viral or bacterial infections, are important as they are linked to a poor prognosis. The mainstay of the management of stable disease is the use of inhaled long-acting bronchodilators, whereas corticosteroids are beneficial primarily in patients who have coexisting features of asthma, such as eosinophilic inflammation and more reversibility of airway obstruction. Apart from smoking cessation, no treatments reduce disease progression. More research is needed to better understand disease mechanisms and to develop new treatments that reduce disease activity and progression. PMID:27189863

    Full Text Available Introduction and Objectives: Microvascular angina is common in postmenopausal women. Myocardial ischemia was induced by stress testing, and reports have been published about the relationship between endothelial dysfunction and myocardial perfusion. The objective of this research was to determine whether myocardial ischemia can be evidenced by abnormalities in perfusion and function, as detected by myocardial scintigraphy in women with typical angina, normal coronary angiography and endothelial dysfunction. Methods: 59 women underwent lipid and endothelial function measurements by brachial artery ultrasound, in addition, a 24-hour ECG study (Holter. During the scintigraphy a stress-rest protocol was applied. Patients were divided into two groups according to presence (group I or absence (group II of myocardial perfusion defects. Results: 21 patients showed perfusion defects. 57 % of group I exhibited greater endothelial dysfunction. Only twelve patients showed reversible perfusion defects, and 75 % of the cases was associated with a reduction of post-stress left ventricular ejection fraction, greater than 5 %, and regional abnormalities of wall motion. Three patients in group I showed evidence of ischemia compared with four in Group II. Conclusions: The stress-induced ischemia was associated with a reduced post-stress ejection fraction and endothelial dysfunction in the studied women, and no ischemic changes in the Holter were found.

    Methylprednisolone markedly reduces autophagy and apoptosis after secondary spinal cord injury. Here, we investigated whether pretreat-ment of cells with methylprednisolone would protect neuron-like cells from subsequent oxidative damagevia suppression of autophagy and apoptosis. Cultured N2a cells were pretreated with 10 µM methylprednisolone for 30 minutes, then exposed to 100 µM H2O2 for 24 hours. Inverted phase contrast microscope images, MTT assay, lfow cytometry and western blot results showed that, compared to cells ex-posed to 100 µM H2O2 alone, cells pretreated with methylprednisolone had a signiifcantly lower percentage of apoptotic cells, maintained a healthy morphology, and showed downregulation of autophagic protein light chain 3B and Beclin-1 protein expression. These ifndings indicate that methylprednisolone exerted neuroprotective effects against oxidative damage by suppressing autophagy and apoptosis.

The nitric oxide (NO) donor sodium nitroprusside (SNP) increased in SA-β-Gal-positive cells in cultured human fibroblasts and mouse keratinocytes, and DCP-LA significantly inhibited the effect of SNP. Moreover, SNP induced cell death in cultured mouse keratinocytes, and DCP-LA significantly prevented NO stress-induced death of keratinocytes. Taken together, these results indicate that DCP-LA exerts an antiaging action on the skin. PMID:27310436

    Full Text Available Background: As an acute phase protein, α1-antitrypsin (AAT has been extensively studied in acute coronary syndrome, but it is unclear whether a relationship exists between AAT and stable angina pectoris (SAP. The purpose of the present study was to investigate the association between AAT plasma levels and SAP. Methods: Overall, 103 SAP patients diagnosed by coronary angiography and clinical manifestations and 118 control subjects matched for age and gender were enrolled in this case-control study. Plasma levels of AAT, high-sensitivity C-reactive protein (hsCRP, lipid profiles and other clinical parameters were assayed for all participants. The severity of coronary lesions was evaluated based on the Gensini score (GS assessed by coronary angiography. Results: Positively correlated with the GS (r = 0.564, P < 0.001, the plasma AAT level in the SAP group was significantly higher than that in the control group (142.08 ± 19.61 mg/dl vs. 125.50 ± 19.67 mg/dl, P < 0.001. The plasma AAT level was an independent predictor for both SAP (odds ratio [OR] = 1.037, 95% confidence interval [CI]: 1.020-1.054, P < 0.001 and a high GS (OR = 1.087, 95% CI: 1.051-1.124, P < 0.001 in a multivariate logistic regression model. In the receiver operating characteristic curve analysis, plasma AAT level was found to have a larger area under the curve (AUC for predicting a high GS (AUC = 0.858, 95% CI: 0.788-0.929, P < 0.001 than that of hsCRP (AUC = 0.665, 95% CI: 0.557-0.773, P = 0.006; Z = 2.9363, P < 0.001, with an optimal cut-off value of 137.85 mg/dl (sensitivity: 94.3%, specificity: 68.2%. Conclusions: Plasma AAT levels correlate with both the presence and severity of coronary stenosis in patients with SAP, suggesting that it could be a potential predictive marker of severe stenosis in SAP patients.

    Background:As an acute phase protein,α1-antitrypsin (AAT) has been extensively studied in acute coronary syndrome,but it is unclear whether a relationship exists between AAT and stable angina pectoris (SAP).The purpose of the present study was to investigate the association between AAT plasma levels and SAP.Methods:Overall,103 SAP patients diagnosed by coronary angiography and clinical manifestations and 118 control subjects matched for age and gender were enrolled in this case-control study.Plasma levels of AAT,high-sensitivity C-reactive protein (hsCRP),lipid profiles and other clinical parameters were assayed for all participants.The severity of coronary lesions was evaluated based on the Gensini score (GS) assessed by coronary angiography.Results:Positively correlated with the GS (r =0.564,P < 0.001),the plasma AAT level in the SAP group was significantly higher than that in the control group (142.08 ± 19.61 mg/dl vs.125.50 ± 19.67 mg/dl,P < 0.001).The plasma AAT level was an independent predictor for both SAP (odds ratio [OR] =1.037,95% confidence interval [CO:1.020-1.054,P < 0.001) and a high GS (OR =1.087,95% CI:1.051-1.124,P < 0.001) in a multivariate logistic regression model.In the receiver operating characteristic curve analysis,plasma AAT level was found to have a larger area under the curve (AUC) for predicting a high GS (AUC =0.858,95% CI:0.788-0.929,P < 0.001) than that of hsCRP (AUC =0.665,95% CI:0.557-0.773,P =0.006; Z =2.9363,P < 0.001),with an optimal cut-off value of 137.85 mg/dl (sensitivity:94.3%,specificity:68.2%).Conclusions:Plasma AAT levels correlate with both the presence and severity of coronary stenosis in patients with SAP,suggesting that it could be a potential predictive marker of severe stenosis in SAP patients.

    High sensitivity C-reactive protein (hs-CRP) is commonly used in clinical practice to assess cardiovascular risk. However, a correlation has not yet been established between the absolute levels of peripheral and central hs-CRP. To assess the correlation between serum hs-CRP levels (mg/L) in a peripheral vein in the left forearm (LFPV) with those in the coronary sinus (CS) of patients with coronary artery disease (CAD) and a diagnosis of stable angina (SA) or unstable angina (UA). This observational, descriptive, and cross-sectional study was conducted at the Instituto do Coração, Hospital das Clinicas, Faculdade de Medicina, Universidade de São Paulo, and at the Hospital Beneficência Portuguesa de Sao Paulo, where CAD patients referred to the hospital for coronary angiography were evaluated. Forty patients with CAD (20 with SA and 20 with UA) were included in the study. Blood samples from LFPV and CS were collected before coronary angiography. Furthermore, analysis of the correlation between serum levels of hs-CRP in LFPV versus CS showed a strong linear correlation for both SA (r = 0.993, p < 0.001) and UA (r = 0.976, p < 0.001) and for the entire sample (r = 0.985, p < 0.001). Our data suggest a strong linear correlation between hs-CRP levels in LFPV versus CS in patients with SA and UA.

    Objective: To investigate the effect of platelet membrane glycoprotein(GP) Ⅰ a gene polymorphism in the pathogenesis of unstable angina pectoris (UAP) in Chinese people. Methods: Collagen type Ⅰ -induced platelet aggregation was measured in 33healthy subjects in vitro. Plasma level of α-granule membrane protein (GMP-140) was measured in both the above 33 healthy subjects during fasting and 35 patients with recent onset effort anina during rest onset within 24 h after hospitalization. Furthermore, the platelet membrane GP Ⅰ a gene 807C/T polymorphism was checked in all subjects with polymerase chain reaction-sequence specific primers(PCR-SSP)technique. Results: The lag time before 30% platelet aggregation was significantly longer in healthy subjects with CC genotype than with TC genotype ( P <0.01). However, there was no significant difference in the maximal platelet aggregation between healthy subjects with the above two genotypes. Plasma level of GMP-140 was significantly higher in TC genotypic patients with recent onset effort angina than in CC genotypic patients with the same type of UAP( P < 0.05) and healthy subjects ( P < 0.01), furthermore, there was also significant difference between the latter two groups( P < 0.05). Conclusion: The rapid initiation of collagen-induced platelet aggregation may be associated with platelet membrane GP Ⅰ a T807 allele, which may play an important role in the pathogenesis of UAP.

  13. The effects of lidoflazine on exercise performance and thallium stress scintigraphy in patients with stable angina pectoris

    International Nuclear Information System (INIS)

    Lidoflazine is a synthetic drug with calcium-channel blocking effects. In a 7-month study, 36 patients with stable angina pectoris were tested during a 3-month single-blind placebo phase. Nineteen were then randomized by double-blind methods to lidoflazine and 17 to placebo therapy. The lidoflazine group had a significant (p < 0.01) reduction in anginal attacks; the placebo group did not. Exercise testing demonstrated that lidoflazine therapy was associated with a 34% increase in total work performance and a 15.6% increase in peak calculated oxygen uptake during double-blind treatment (both p < 0.004 compared with the placebo group). Heart rate was significantly reduced at submaximal levels of exercise during lidoflazine therapy (p < 0.04). Nitroglycerin consumption and electrocardiographic changes at the end of exercise did not change during the double-blind phase. In a second study of six similar patients, single-blind administration of lidoflazine was associated with improved myocardial perfusion during exercise as determined by thallium-201 stress scintigraphy. These studies demonstrate that lidoflazine therapy is associated with relief of angina, an increased physical work capacity, and improved regional myocardial perfusion during exercise

    Full Text Available In clinical practice, deep brain stimulation (DBS is effective for treatment of motor symptoms in Parkinson's disease (PD. However, the mechanisms have not been understood completely. There are some reports that electrical stimulation exerts neuroprotective effects on the central nervous system diseases including cerebral ischemia, head trauma, epilepsy and PD, although there are a few reports on neuroprotective effects of spinal cord stimulation (SCS. We investigated the neuroprotective effects of high cervical SCS on PD model of rats. Adult female Sprague-Dawley rats received hour-long SCS (2, 50 or 200 Hz with an epidural electrode at C1-2 level for 16 consecutive days. At 2 days after initial SCS, 6-hydroxydopamine (6-OHDA was injected into the right striatum of rats. Behavioral evaluations of PD symptoms were employed, including cylinder test and amphetamine-induced rotation test performed at 1 and 2 weeks after 6-OHDA injection. Animals were subsequently euthanized for immunohistochemical investigations. In order to explore neurotrophic and growth factor upregulation induced by SCS, another cohort of rats that received 50 Hz SCS was euthanized at 1 and 2 weeks after lesion for protein assays. Behavioral tests revealed that the number of amphetamine-induced rotations decreased in SCS groups. Immunohistochemically, tyrosine hydroxylase (TH-positive fibers in the striatum were significantly preserved in SCS groups. TH-positive neurons in the substantia nigra pars compacta were significantly preserved in 50 Hz SCS group. The level of vascular endothelial growth factor (VEGF was upregulated by SCS at 1 week after the lesion. These results suggest that high cervical SCS exerts neuroprotection in PD model of rats, at least partially by upregulation of VEGF. SCS is supposed to suppress or delay PD progression and might become a less invasive option for PD patients, although further preclinical and clinical investigations are needed to confirm the

    1984-05-01

    Chronicity in psychopathology is indicative of a term, a decay. Chronicization only leads the way to this term. Here, chronicization is taken literally as an inscription in the time course of delusions. The mechanism of systematization seems to be a central mark in the approach to chronic delusions. It is not an alienation or an irreversible closing but an attempted accommodation with reality in the life of psychotic subjects, irrespective of the delusional structure. The role of therapy and drug treatment as a follow-up may in that case assume another meaning.

  17. Pancreatic adenocarcinoma exerts systemic effects on the peripheral blood myeloid and plasmacytoid dendritic cells: an indicator of disease severity?

    International Nuclear Information System (INIS)

    Dendritic cells (DCs) isolated from tumor bearing animals or from individuals with solid tumors display functional abnormalities and the DC impairment has emerged as one mechanism for tumor evasion from the control of the immune system. Ductal pancreatic adenocarcinoma (PDAC), the most common pancreatic cancer, is recognized as a very aggressive cancer type with a mortality that almost matches the rate of incidence. We examined the systemic influence ductal pancreatic adenocarcinoma (PDAC) exerted on levels of peripheral blood DCs and inflammatory mediators in comparison to the effects exerted by other pancreatic tumors, chronic pancreatitis, and age-matched controls. All groups examined, including PDAC, had decreased levels of myeloid DCs (MDC) and plasmacytoid DCs (PDC) and enhanced apoptosis in these cells as compared to controls. We found elevated levels of PGE2 and CXCL8 in subjects with PDAC, and chronic pancreatitis. Levels of these inflammatory factors were in part restored in PDAC after tumor resection, whereas the levels of DCs were impaired in the majority of these patients ~12 weeks after tumor removal. Our results prove that solid pancreatic tumors, including PDAC, systemically affect blood DCs. The impairments do not seem to be tumor-specific, since similar results were obtained in subjects with chronic pancreatitis. Furthermore, we found that PDAC patients with a survival over 2 years had significant higher levels of blood DCs compared to patients with less than one year survival. Our findings points to the involvement of inflammation in the destruction of the blood MDCs and PDCs. Furthermore, the preservation of the blood DCs compartment in PDAC patients seems to benefit their ability to control the disease and survival

The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.

    Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease that manifests in hypoxemia, inactivity, and poor prognosis. This study aimed to assess the prognostic role of physical activity (PA) and exertional desaturation (ED) with mortality in IPF. At baseline, 34 IPF patients (68 (50–81) years) were interviewed using the International Physical Activity Questionnaire (IPAQ), and SpO2 was assessed pre to post 6-min walking test (∆SpO2). Patients were prospectively followed up for 40 months. Receiver operating characteristics curve analysis determined cut-off points associated with mortality, and Cox proportional hazard ratio (HR) were conducted. Thresholds for increased mortality risk in IPF patients were determined as IPAQ ≤ 417 metabolic equivalent task (METS)-min/week, p = 0.004 (HR; 9.7, CI 95% (1.3–71.9), p = 0.027), and ∆SpO2 ≥ 10%, p = 0.002, (HR; 23.3, CI 95% (1.5–365), p = 0.025). This study demonstrated a significant association of PA and ED with mortality in IPF patients. The findings emphasize the clinical importance of PA and ED assessments to aid in IPF risk stratification, prognosis prediction, and in providing early appropriate treatments, such as pulmonary rehabilitation, PA consultation, oxygen supplementation, and lung transplantation referral. These results underscore that even low levels of PA corresponding to 100–105 min/week were associated with a reduced mortality risk and better survival in IPF. PMID:27548238

    Chronic urticaria is the most common skin diseases, characterized by chronic cutaneous lesions which severely debilitates patients in several aspects of their everyday life. Vitamin D is known to exert several actions in the immune system and to influence function and differentiation of mast cells, central role players in the pathogenesis of chronic idiopathic urticaria. This study was performed to evaluate the relationship between vitamin D levels and susceptibility to chronic idiopathic urticaria. One hundred and fourteen patients with chronic idiopathic urticaria were recruited in this study along with one hundred and eighty seven sex-matched and age-matched healthy volunteers as the control group. For each patient, urticaria activity score was calculated and autologous serum skin test was done. Vitamin D metabolic statue was measured in serum as 25 hydroxyvitamin D using enzyme immunoassay method. Patients with chronic idiopathic urticaria significantly showed lower levels of vitamin D. Vitamin D deficiency was significantly associated with increased susceptibility to chronic idiopathic urticaria. There was a significant positive correlation between vitamin D levels and urticaria activity score. This study showed that patients with chronic idiopathic urticaria had reduced levels of vitamin D, while vitamin D deficiency could increase susceptibility to chronic idiopathic urticaria.

  8. Effect of radiation exerted to creep rate of resin

    International Nuclear Information System (INIS)

    One of the high performance composite materials which became to be manufactured by the progress of working techniques and the improvement of material performance is fiber-reinforced plastics (FRP). Carbon fiber-reinforced plastics (CFRP) are used as space and aircraft material, and glass fiber-reinforced plastics (GFRP) are expected as the structural material for superconducting magnets in nuclear fusion. In these materials, the use for long term must be considered, and the creep characteristics, of resin should be taken as one of the design factors. Therefore, the effect that radiation exerted to the stress relaxation of epoxy resin was measured, and its mechanism was investigated. The sample was bisphenol F system epoxy. The measurements of DSC, dynamic viscoelasticity and stress relaxation were carried out. The stress relaxation in bisphenol F system epoxy resin occurred down to 10 % of the initial stress only at 3 MGy. This is the dose far lower than the life in the radiation resistance of this resin. It is considered that the stress relaxation of the resin was caused by the change in molecular structure instead of the cut of molecular chain, as energy was given to the microscopic region by the interaction with radiation.

    Current treatment strategies for anxiety disorders are predominantly symptom-based. However, a third of anxiety patients remain unresponsive to anxiolytics highlighting the need for more effective, mechanism-based therapeutic approaches. We have previously compared high vs low anxiety mice and identified changes in mitochondrial pathways, including oxidative phosphorylation and oxidative stress. In this work, we show that selective pharmacological targeting of these mitochondrial pathways exerts anxiolytic effects in vivo. We treated high anxiety-related behavior (HAB) mice with MitoQ, an antioxidant that selectively targets mitochondria. MitoQ administration resulted in decreased anxiety-related behavior in HAB mice. This anxiolytic effect was specific for high anxiety as MitoQ treatment did not affect the anxiety phenotype of C57BL/6N and DBA/2J mouse strains. We furthermore investigated the molecular underpinnings of the MitoQ-driven anxiolytic effect and found that MitoQ treatment alters the brain metabolome and that the response to MitoQ treatment is characterized by distinct molecular signatures. These results indicate that a mechanism-driven approach based on selective mitochondrial targeting has the potential to attenuate the high anxiety phenotype in vivo, thus paving the way for translational implementation as long-term MitoQ administration is well-tolerated with no reported side effects in mice and humans.

    Full Text Available Astaxanthin (ATX is a xanthophyll carotenoid which has been approved by the United States Food and Drug Administration (USFDA as food colorant in animal and fish feed. It is widely found in algae and aquatic animals and has powerful anti-oxidative activity. Previous studies have revealed that ATX, with its anti-oxidative property, is beneficial as a therapeutic agent for various diseases without any side effects or toxicity. In addition, ATX also shows preclinical anti-tumor efficacy both in vivo and in vitro in various cancer models. Several researches have deciphered that ATX exerts its anti-proliferative, anti-apoptosis and anti-invasion influence via different molecules and pathways including signal transducer and activator of transcription 3 (STAT3, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB and peroxisome proliferator-activated receptor gamma (PPARγ. Hence, ATX shows great promise as chemotherapeutic agents in cancer. Here, we review the rapidly advancing field of ATX in cancer therapy as well as some molecular targets of ATX.

    Omran, Ahmed Fathy

    Self-consolidating concrete (SCC) is an emerging technology that utilizes flowable concrete that eliminates the need for consolidation. The advantages of SCC lie in a remarkable reduction of the casting time, facilitating the casting of congested and complex structural elements, possibility to reduce labor demand, elimination of mechanical vibrations and noise, improvement of surface appearance, producing a better and premium concrete product. The research focussed on capturing existing knowledge and making recommendations for current practice. An experimental program was undertaken at the Universite de Sherbrooke to evaluate the lateral pressure developed by SCC mixtures. A portable devise (UofS2 pressure column) for measuring and predicting lateral pressure and its rate of decay of SCC was developed and validated. The UofS2 pressure column is cast with 0.5 m high fresh concrete and air pressure is introduced from the top to simulate casting depth up to 13 m. Then, develop and implement test method for field evaluation of relevant plastic and thixotropic properties of SCC that affect formwork pressure were done. Portable vane (PV) test based on the hand-held vane test method used to determine the undrained shear strength property of clay soil was the first setup as well as the inclined plane (IP) test. The IP device involves slumping a small concrete cylinder on a horizontal plate and then lifting up the plate at different durations of rest until the slumped sample starts to move. Identifying role of material constituents, mix design, concrete placement characteristics (casting rate, waiting periods between lifts, and casting depth), temperature, and formwork characteristics that have major influence on formwork pressure exerted by SCC were evaluated in laboratory and validated by actual field measurements. Relating the maximum lateral pressure and its rate of decay to the plastic properties of SCC were established. In the analytical part of the research

    RESCUE is a phase III, randomized, controlled, multicenter, comparative efficacy study, designed to compare two diagnostic imaging/treatment paradigms that use coronary computed tomography angiography (CCTA) or single photon emission computed tomography myocardial perfusion imaging (SPECT MPI) for assisting in the diagnosis of ischemic heart disease in patients with stable angina symptoms, and guiding subsequent treatment. The study is based on the hypothesis that CCTA as a diagnostic tool is associated with no increase in cardiac risk, decreased cost, and reduced radiation exposure compared with SPECT MPI. The RESCUE trial was funded by the Agency for Healthcare Research and Quality (AHRQ) and the American College of Radiology Imaging Network (ACRIN) Fund for Imaging Innovation, began in 2011, and completed in 2014.

    Full Text Available Cardiac Syndrome X (CSX was considered a stable coronary syndrome, yet due to its nature, CSX symptoms often have a great impact on patients’ Quality of Life (QoL. According to ESC 2013 stable coronary artery disease criteria, CSX was replaced by Microvascular Angina (MA.Unfortunately, most CSX or MA patients, after classical angina (involving main coronary vessels has been ruled out, often do not receive proper treatment. Indications for pharmacological treatment of MA patients were introduced only recently. Another problematic issue is that scientists describing the pathophysiology of both CSX and MA stress a lack of a deeper insight into the multifactorial etiology of the source of pain associated with this disease. In the presented article we have attempted to study the influence of cardiac rehabilitation (3 months programme on the QoL of patients recognized as suffering from MA, as well as to check if changes in myocardial perfusion in these patients at baseline and after completion of cardiac rehabilitation match changes in their QoL. Therefore, after screening 436 women for MA, we studied 55 of them who were confirmed as having MA and who agreed to participate in the study. Exercise tests, Myocardial Perfusion Imaging, and QoL questionnaires were studied at baseline and after completing 3 months period of cardiac rehabilitation. Results were subsequently compared, which showed a link between improved perfusion score in SPECT study and improved overall physical capacity, on one hand, and improved QoL score on the other. These results confirm that cardiac rehabilitation is a very useful treatment option for MA patients. It seems that training during cardiac rehabilitation is a very important factor (improved physical efficiency –> increase in self-belief, and that taking into consideration the multifactor pathophysiology of pain, it is connected with a better quality of life for MA patients.

    Full Text Available The work aims to investigate the in vitro release, pharmacokinetics (PK, pharmacodynamics (PD and PK–PD relationships of Salvianolic Acid B micro-porous osmotic pump pellets (SalB-MPOPs in angina pectoris New Zealand White (NZW rabbits, compared with those of SalB immediate-release pellets (SalB-IRPs. The SalB plasma concentrations and Superoxide dismutase levels (PD index were recorded continuously at predetermined time interval after administration, and the related parameters were calculated by using WinNonlin software. The release profile of MPOPs was more sustained than that of IRPs. PK results indicated that the mean Cmax was significantly lower, the SalB plasma concentrations were steadier, both area under concentration-time curve from 0 to 24 h (AUC0–24 h and from 0 to infinity (AUC0–∞ were presented larger, and both the peak concentration time (Tmax and mean residence time (MRT were prolonged for MPOPs, as compared with those of IRPs. PD results suggested that peak drug effect (Emax was lower and the equilibration rate constant (ke0 between the central compartment and the effect compartment was higher of MPOPs vs. those of IRPs. PK–PD relationships demonstrated that the effect-concentration-time (ECT course of MPOPs was clockwise hysteresis loop, and that of IRPs was counter-clockwise hysteresis loop. Collectively, those results demonstrated that MPOPs were potential formulations in treating angina pectoris induced by atherosclerosis.

    No studies of cystic fibrosis (CF) have systematically characterized the evolution of the qualitative dimensions of exertional dyspnea. Adults with CF (n = 25) and control individuals matched for sex, age, and body mass index (n = 25) underwent cardiopulmonary cycle exercise testing with a detailed evaluation of ventilatory and dyspnea responses. The qualitative dimensions of dyspnea were examined during each exercise stage by having subjects select phrases that best described their breathing (i.e., "work/effort," "unsatisfied inspiration," and "unsatisfied expiration"). Subjects also selected phrases that described the quality of their breathing at peak exercise using an established 15-item questionnaire, which was then clustered into different categories. Subjects with CF had greater ventilatory requirements, higher end-inspiratory and end-expiratory lung volumes (% total lung capacity), and an earlier inflection/plateau in tidal volume during exercise compared with control subjects. Increased work/effort was the dominant qualitative descriptor in both groups throughout exercise. Unsatisfied inspiration was selected by 48% of subjects with CF and 40% of controls at some point during exercise. The onset of unsatisfied inspiration in these subjects occurred at a significantly lower relative exercise intensity in subjects with CF vs. controls (72 ± 21 vs. 94 ± 11% Wmax, P < 0.01). Chest tightness was the only qualitative descriptor cluster that was selected more frequently by subjects with CF vs. controls (36 vs. 0%, respectively, P < 0.05) at peak exercise. Therapeutic interventions that reduce ventilatory requirements and improve lung volumes may delay the onset of distressing sensations such as unsatisfied inspiration and chest tightness in adults with CF.

    Recent studies demonstrate that rehabilitation ameliorates physical and cognitive impairments of patients with stroke, spinal cord injury, and other neurological diseases and that rehabilitation also has potencies to modulate brain plasticity. Here we examined the effects of compulsive exercise on Parkinson's disease model of rats. Before 6-hydroxydopamine (6-OHDA, 20 microg) lesion into the right striatum of female SD rats, bromodeoxyuridine (BrdU) was injected to label the proliferating cells. Subsequently, at 24 h after the lesion, the rats were forced to run on the treadmill (5 days/week, 30 min/day, 11 m/min). As behavioral evaluations, cylinder test was performed at 1, 2, 3, and 4 weeks and amphetamine-induced rotational test was performed at 2 and 4 weeks with consequent euthanasia for immunohistochemical investigations. The exercise group showed better behavioral recovery in cylinder test and significant decrease in the number of amphetamine-induced rotations, compared to the non-exercise group. Correspondingly, significant preservation of tyrosine hydroxylase (TH)-positive fibers in the striatum and TH-positive neurons in the substantia nigra pars compacta (SNc) was demonstrated, compared to the non-exercise group. Additionally, the number of migrated BrdU- and Doublecortin-positive cells toward the lesioned striatum was increased in the exercise group. Furthermore, brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor increased in the striatum by exercise. The results suggest that exercise exerts neuroprotective effects or enhances the neuronal differentiation in Parkinson's disease model of rats with subsequent improvement in deteriorated motor function.

    Summary This investigation examined the validity of newly developed Adult OMNI Elliptical Ergometer Ratings of Perceived Exertion Scales. Sixty men and women performed a graded exercise test on an elliptical ergometer. Oxygen consumption (VO2), heart rate (HR) and ratings of perceived exertion were recorded each stage from the Borg 15 Category Scale and two different OMNI scales. One scale employed an elliptical ergometer format of the OMNI Picture System of Perceived Exertion. The second scale modified verbal, numerical, and pictorial descriptors at the low end of the response range. Concurrent and construct validity were established by the positive relation between ratings of perceived exertion from each OMNI scale with VO2, HR and Borg Scale ratings of perceived exertion (men, r = .94–.97; women, r = .93–.98). Validity was established for both OMNI scales, indicating either metric can be used to estimate ratings of perceived exertion during partial weight bearing exercise. PMID:21319623

    Peripheral painful neuropathy is one of the most common complications in diabetes and necessitates improved treatment. Secoisolariciresinol diglycoside (SDG), a predominant lignan in flaxseed, has been shown in our previous studies to exert antidepressant-like effect. As antidepressant drugs are clinically used to treat chronic neuropathic pain, this work aimed to investigate the potential analgesic efficacy of SDG against diabetic neuropathic pain in a mouse model of type 1 diabetes. We subjected mice to diabetes by a single intraperitoneal (i.p.) injection of streptozotocin (STZ, 200 mg/kg), and Hargreaves test or von Frey test was used to assess thermal hyperalgesia or mechanical allodynia, respectively. Chronic instead of acute SDG treatment (3, 10 or 30 mg/kg, p.o., twice per day for three weeks) ameliorated thermal hyperalgesia and mechanical allodynia in diabetic mice, and these analgesic actions persisted about three days when SDG treatment was terminated. Although chronic treatment of SDG to diabetic mice did not impact on the symptom of hyperglycemia, it greatly attenuated excessive oxidative stress in sciatic nerve and spinal cord tissues, and partially counteracted the condition of weight decrease. Furthermore, the analgesic actions of SDG were abolished by co-treatment with the reactive oxygen species donor tert-butyl hydroperoxide (t-BOOH), but potentiated by the reactive oxygen species scavenger phenyl-N-tert-butylnitrone (PBN). These findings indicate that chronic SDG treatment can correct neuropathic hyperalgesia and allodynia in mice with type 1 diabetes. Mechanistically, the analgesic actions of SDG in diabetic mice may be associated with its antioxidant activity. PMID:26494631

    The tetracycline antibiotic minocycline can exert strong anti-inflammatory, antioxidant, and antiapoptotic effects. There is cumulating evidence that epileptogenic brain insults trigger neuroinflammation and anti-inflammatory concepts can modulate the process of epileptogenesis. Based on the mechanisms of action discussed for minocycline, the compound is of interest for intervention studies as it can prevent the polarization of microglia into a pro-inflammatory state. Here, we assessed the efficacy of sub-chronic minocycline administration initiated immediately following an electrically-induced status epilepticus in rats. The treatment did not affect the development of spontaneous seizures. However, minocycline attenuated behavioral long-term consequences of status epilepticus with a reduction in hyperactivity and hyperlocomotion. Furthermore, the compound limited the spatial learning deficits observed in the post-status epilepticus model. The typical status epilepticus-induced neuronal cell loss was evident in the hippocampus and the piriform cortex. Minocycline exposure selectively protected neurons in the piriform cortex and the hilus, but not in the hippocampal pyramidal layer. In conclusion, the data argue against an antiepileptogenic effect of minocycline in adult rats. However, the findings suggest a disease-modifying impact of the tetracycline affecting the development of behavioral co-morbidities, as well as long-term consequences on spatial learning. In addition, minocycline administration resulted in a selective neuroprotective effect. Although strong anti-inflammatory effects have been proposed for minocycline, we could not verify these effects in our experimental model. Considering the multitude of mechanisms claimed to contribute to minocycline's effects, it is of interest to further explore the exact mechanisms underlying the beneficial effects in future studies.

    The aim of this study was to assess the relationship between external measures of resistance training (RT) workload and intensity, volume load (VL) and training intensity (TI), and related internal measures, session load and session rating of perceived exertion (sRPE), across a chronic RT intervention and between different models of RT in older adults. Forty-one healthy, untrained older adults (female, 21; male, 20; age, 70.9 ± 5.1 years; height, 166.3 ± 8.2 cm; weight, 72.9 ± 13.4 kg) were randomly stratified into 3 RT groups: nonperiodized (NP), block periodized (BP), or daily undulating periodized (DUP). They completed a 22-week RT intervention at a frequency of 3 d·wk. All training was executed on RT machines, and training volume was equalized between training groups based on total repetitions. Session RPE was measured 10-15 minutes after each training session. There were no meaningful relationships between VL and session load or TI and sRPE. Also, no significant differences were detected between training groups for mean sRPE across the training intervention. Based on these results, session load and sRPE do not appear to be valid markers of RT workload and intensity when compared with established external measures in healthy untrained older adults. However, sRPE and session load may hold promise as monitoring tools in RT that do not involve training to muscular failure. Furthermore, sRPE does not significantly differ between NP, BP, and DUP RT models, highlighting that this measure is not sensitive to such periodization as evident in the present study.

    AMP-activated protein kinase (AMPK), which is a pivotal guardian of whole-body energy metabolism, has become an attractive therapeutic target for metabolic syndrome. Previously, using a homogeneous scintillation proximity assay, we identified the small-molecule AMPK activator C24 from an optimization based on the original allosteric activator PT1. In this paper, the AMPK activation mechanism of C24 and its potential beneficial effects on glucose and lipid metabolism on db/db mice were investigated. C24 allosterically stimulated inactive AMPK α subunit truncations and activated AMPK heterotrimers by antagonizing autoinhibition. In primary hepatocytes, C24 increased the phosphorylation of AMPK downstream target acetyl-CoA carboxylase dose-dependently without changing intracellular AMP/ATP ratio, indicating its allosteric activation in cells. Through activating AMPK, C24 decreased glucose output by down-regulating mRNA levels of phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase) in primary hepatocytes. C24 also decreased the triglyceride and cholesterol contents in HepG2 cells. Due to its improved bioavailability, chronic oral treatment with multiple doses of C24 significantly reduced blood glucose and lipid levels in plasma, and improved the glucose tolerance of diabetic db/db mice. The hepatic transcriptional levels of PEPCK and G6Pase were reduced. These results demonstrate that this orally effective activator of AMPK represents a novel approach to the treatment of metabolic syndrome. - Highlights: • C24 activates AMPK through antagonizing autoinhibition within α subunit. • C24 activates AMPK in hepatocytes and decreases glucose output via AMPK. • C24 exerts beneficial effects on diabetic db/db mice. • C24 represents a novel therapeutic for treatment of metabolic syndrome.

    Background: Hypoadiponectinemia has been associated with states of chronic inflammation in humans. Mesenteric fat hypertrophy and low adiponectin have been described in patients with Crohn\\'s disease. We investigated whether adiponectin and the plant-derived homolog, osmotin, are beneficial in a murine model of colitis. Methods: C57BL/6 mice were injected (i.v.) with an adenoviral construct encoding the full-length murine adiponectin gene (AN+DSS) or a reporter-LacZ (Ctr and V+DSS groups) prior to DSS colitis protocol. In another experiment, mice with DSS colitis received either osmotin (Osm+DSS) or saline (DSS) via osmotic pumps. Disease progression and severity were evaluated using body weight, stool consistency, rectal bleeding, colon lengths, and histology. In vitro experiments were carried out in bone marrow-derived dendritic cells. Results: Mice overexpressing adiponectin had lower expression of proinflammatory cytokines (TNF, IL-1β), adipokines (angiotensin, osteopontin), and cellular stress and apoptosis markers. These mice had higher levels of IL-10, alternative macrophage marker, arginase 1, and leukoprotease inhibitor. The plant adiponectin homolog osmotin similarly improved colitis outcome and induced robust IL-10 secretion. LPS induced a state of adiponectin resistance in dendritic cells that was reversed by treatment with PPARγ agonist and retinoic acid. Conclusion: Adiponectin exerted protective effects during murine DSS colitis. It had a broad activity that encompassed cytokines, chemotactic factors as well as processes that assure cell viability during stressful conditions. Reducing adiponectin resistance or using plant-derived adiponectin homologs may become therapeutic options in inflammatory bowel disease. © 2011 Springer Science+Business Media, LLC.

    Full Text Available Purpose: To evaluate bone mineral density (BMD measurements and the presence of periodontitis in patients with acromegaly, as well as to inquire the impact of interfering factors. Material and Method: Forty-seven acromegalic patients with any accompanying condition known to affect calcium-bone metabolism and 60 age-matched healthy controls were included. Age, gender, duration and activity of acromegaly, past-present therapy options, pituitary hormone profiles, replacement therapies, and the results of periodontal analysis were recorded. Results: Eighteen patients were male (38.3%, 29 were female (61.7%. The mean age of the patients was 46.6±11.5 years, twenty-five (53.1% had active, 22 (46.8% had inactive acromegaly. The latter were older and had longer disease duration (p=0.04, p=0.003, respectively. Serum calcium and phosphorus levels, 24-hour urinary calcium excretion and BMD at the lumbar spine and femur neck insignificantly associated with disease activity (p>0.05. Osteoporosis was detected in 6 patients (12.76%. Periodontitis and advanced periodontitis were more common in control group (66.7% vs. 44.7%, (43.3% vs. 12.8% (p=0.022, p=0.0001, respectively. There was no difference in chronic periodontitis and severity between active and inactive groups (48% vs. 40.9%; p=0.279. No difference was noted in other study parameters, as well. Repeated measures analysis of variance demonstrated statistically insignificant distribution between GH change in time and periodontitis subgroups. Discussion: We demonstrated that acromegaly exerted no clear negative impact on vertebral BMD in the absence of overt hypogonadism. Regardless of disease activity, acromegaly cases exhibited lower rates of periodontitis with less severity which remained unchanged in the presence of accompanying metabolic disorders known to have negative impact on periodontal tissue. Chronic exposure to excess GH may have a protective role against periodontitis. Turk Jem 2015; 19: 42-48

    Bell, DR, Pennuto, AP, and Trigsted, SM. The effect of exertion and sex on vertical ground reaction force variables and landing mechanics. J Strength Cond Res 30(6): 1661-1669, 2016-The purpose of this investigation was to determine how exertion and sex affected a variety of vertical ground reaction force (VGRF) parameters during a jump-landing task, including peak VGRF, peak VGRF asymmetry, loading rate, and loading rate asymmetry. Additionally, we wanted to determine whether landing mechanics changed after exertion as measured by the Landing Error Scoring System (LESS). Forty recreationally active participants (20 men and 20 women) completed jump landings from a 30-cm-high box onto force plates before and after repeated bouts of an exercise circuit until a specific rating of perceived exertion was achieved. Three-way (sex × time × limb) analyses of variance were used to analyze variables pre-exertion to postexertion. No significant 3-way interactions were observed for peak VGRF (p = 0.31) or loading rate (p = 0.14). Time by sex interactions were observed for peak VGRF (p = 0.02) and loading rate (p = 0.008). Post hoc analysis revealed that men increased landing force and loading rate after exertion while women did not. Landing mechanics, as assessed by total LESS score, were worse after exertion (p errors for knee flexion landing. Women may be more resistant to exertion compared with men and use different joint controls' strategies to cope with VGRF after exertion. However, VGRF asymmetry is not affected by sex and exertion. Limiting peak VGRF and addressing landing postures, especially after exertion, should be components of injury prevention strategies. PMID:26562710

    The aim of this retrospective study was to determine the relationship between the duration of preceding angina pectoris, collateral circulation and left ventricular function after isolated coronary occlusion with or without myocardial infarction. Coronary angiography of 138 consecutive patients showed isolated and complete occlusions of the left anterior descending (58 patients) or right coronary artery (80 patients). One hundred and four patients had myocardial infarction with (Group A, n = 21) or without (Group B, n = 83) preceding angina pectoris and 34 had angina without myocardial infarction (Group C). The left ventricular ejection fraction was measured by ventriculography in the 30 degrees right anterior oblique projection. The collateral circulation was assessed by coronary angiography and evaluated as follows: no flow or flow limited to collateral branches (subgroup 1) and partial or complete filling of the epicardial arterial segment (subgroup 2). In the global population the left ventricular ejection fraction was higher and the duration of preceding angina pectoris was longer in the subgroups with a well developed collateral circulation. There was no difference in ejection fraction between Groups A and B (presence of myocardial infarction), on the other hand, within each of the groups, a good collateral circulation (subgroup 2) was associated with a significantly higher ejection fraction. Group C (without infarction) patients had better ejection fractions than Groups A or B, especially when the collateral circulation was poorly developed. Within Group C, the quality of the collateral circulation did not seem to affect the ejection fraction. The left ventricular ejection fraction is lower in patients with isolated coronary occlusion and myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)

    Radiolabeled fatty acids such as iodine-123-betamethyl-p-iodophenyl-pentadecanoic acid (BMIPP) have unique metabolic properties suggesting potential use as myocardial perfusion tracers. The uptakes of BMIPP and thallium 201 were compared using single photon emission computed tomography (SPECT) in 24 patients displaying unstable angina with multivessel disease at a mean of 3.4 days after admission. Coronary angiography was performed within a week. Uptake was considered normal if the activity was greater than 80% of the normal area, mildly reduced if 50% to 79%, and severely reduced if less than 50%. The regional activities in four quadrants in short-axis slices were measured from basal, mid and apical sets. We attempted to identify the causative lesion on dual SPECT imaging. We planned the following management of each patient based on the results of the dual SPECT study. BMIPP activity imaging found 4 segments (1.4%) with severe decrease, 70 (24.3%) with mild decrease, and 214 (74.3%) with normal uptake. In contrast, Tl activity imaging showed normal uptake in 68 of 74 abnormal BMIPP activity segments. Furthermore, all segments with abnormal BMIPP uptake were matched with locations of coronary artery stenosis by coronary angiography. Accordingly, coronary revascularization (percutaneous transluminal coronary angioplasty, coronary artery bypass grafting) was performed based on BMIPP SPECT. Reductions in BMIPP activity were common in patients with unstable angina with multivessel disease. BMIPP SPECT is an excellent tool for detecting the causative lesion in unstable angina. The subsequent intervention could be performed with less risk based on the strategy of dilating the only causative lesion which was detected by the BMIPP SPECT in patients with multivessel disease displaying unstable angina.

    Full Text Available Introduction. Rupture of vulnerable atherosclerotic plaques is the cause of most acute coronary syndromes (ACS. Postmortem studies which compared stable coronary lesions and atherosclerotic plaques in patients who have died because of ACS indicated high lipid-core content as one of the major determinants of plaque vulnerability. Objective. Our primary goal was to assess the potential relations of plaque composition determined by IVUS-VH (Intravascular Ultrasound - Virtual Histology in patients with stable angina and subjects in acute phase of ACS without ST segment elevation. Methods. The study comprised of 40 patients who underwent preintervention IVUS examination. Tissue maps were reconstructed from radio frequency data using IVUS-VH software. Results. We analyzed 53 lesions in 40 patients. Stable angina was diagnosed in 24 patients (29 lesions, while acute phase of ACS without ST elevation was diagnosed in 16 patients (24 lesions. In the patients in acute phase of ACS without ST segment elevation IVUS-VH examination showed a significantly larger area of the necrotic core at the site of minimal lumen area and a larger mean of the necrotic core volume in the entire lesion comparing to stable angina subjects (1.84±0.90 mm2 vs. 0.96±0.69 mm2; p<0.001 and 20.94±15.79 mm3 vs. 11.54±14.15 mm3; p<0.05 respectively. Conclusion. IVUS-VH detected that the necrotic core was significantly larger in atherosclerotic lesions in patients in acute phase of ACS without ST elevation comparing to the stable angina subjects and that it could be considered as a marker of plaque vulnerability.

    Full Text Available Background: To examine the fear of pain, anxiety pain symptoms, heart focused anxiety, psychopathology and hostility between patients with infarction and angina. Method: Subjects were 104 patients with infarction or angina, who completed the Hostility and Direction of Hostility Questionnaire, the Symptom Checklist-90-R, Cardiac Anxiety Questionnaire, the Pain Anxiety Symptoms Scale-20 and the Fear of Pain Questionnaire – III. Results: For all patients higher levels of fear and anxiety of pain, heart-focused anxiety psychopathology, and a tendency to develop a hostile attitude were observed. For angina group higher levels of fearfull thinking and total PASS-20, avoidance CAQ, somatization and anxiety (SCL-90. In addition, all patients were found to be significantly correlated (P< .005 with sex, fearfull PASS-20, physiological responses PASS-20, total PASS-20, avoidance CAQ, somatization SCL-90, anxiety SCL-90 Conclusion: There is a variety of general factors that may promote the development of cardiophobia. These processes are likely nonspecific in the sense that they increase the chance of negative emotional responding and poor affect regulatory strategies. For persons exposed to cardiac-related illnesses or persons who model the potential dangers of cardiac-related sensations, there may be an enhanced specificity to that general vulnerability.

  11. Sensitivity and related factors in iodine-123-β-methyl-p-iodophenyl-pentadecanoic acid myocardial scintigraphy to detect stable effort angina pectoris

    International Nuclear Information System (INIS)

    This study evaluated the sensitivity and the related factors in iodine-123-β-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) scintigraphy to detect stable angina. The subjects were 198 patients with stable angina who underwent BMIPP before percutaneous coronary intervention or coronary bypass graft surgery. Patients with unstable angina, myocardial infarction, congestive heart failure, cardiomyopathy and vasospastic angina were excluded. After investigation of the sensitivity of BMIPP, the patients with single-vessel disease without collateral flow were classified into the normal 123I-BMIPP uptake group (normal group) or decreased 123I-BMIPP uptake group (decreased group), and various factors were compared between the two groups. Sensitivity was 61% overall, 58% in single-vessel disease, 69% in double-vessel disease, 53% in triple-vessel disease, 43% in only left main vessel disease, and 89% in left main and other vessel disease (NS). In single-vessel disease, the sensitivity was 40% in 75% coronary artery stenosis, 58% in 90% stenosis, 89% in 99% stenosis, and 69% in total occlusion (p=0.003). Comparing the decreased and normal groups, diabetes mellitus was more frequent in the normal group (14.6% vs 39.5%), minimal lumen diameter was smaller (0.75±0.37 vs 0.98±0.49 mm) and lesion length was longer in the decreased group (15.4±4.9 vs 11.6±5.5 mm). Logistic multivariate analysis showed that the independent factors were diabetes mellitus [odds ratio 0.20, 95% confidence interval (CI) 0.04-0.87, p=0.03], minimal lumen diameter (odds ratio 0.10, 95% CI 0.02-0.48, p=0.003) and lesion length (odds ratio 1.12, 95% CI 1.00-1.25, p=0.03). BMIPP is useful in stable angina patients because of the acceptable sensitivity. Diabetes mellitus, minimal lumen diameter and lesion length were independent factors associated with decreased BMIPP uptake. (author)

    Full Text Available Abstract Background It has been shown that dendritic cells (DCs and fractalkine play a role in accelerating progression of the inflamed atherosclerotic lesions and plaque rupture. We evaluated the numbers and functional changes of DCs and its subsets in human type 2 diabetes with or without unstable angina pectoris (UAP. Methods The study population consisted of 39 diabetic patients (DM:18 without CAD; DM + UAP: 21 with UAP, 18 non-diabetic UAP patients (UAP, and 15 healthy control (Normal. Peripheral blood DCs and its subsets were measured by three color flow cytometry. Serum levels of fractalkine, IL-12, and IFN-α were also measured. The functional status of the monocyte-derived DCs was analyzed by flow cytometry and allogeneic mixed T lymphocytes reaction. Results The percent and absolute numbers of DCs and mDC within the total leukocyte population was similar for Normal and DM, while significantly lower in DM + UAP. pDC numbers were not significantly altered. Serum fractalkine in DM + UAP was highest among the four groups (p = 0.04 vs. UAP, p = 0.0003 vs. DM, p p = 0.01 level. Compared with DM and UAP, the costimulatory molecules CD86 and proliferation of T cells stimulated by DCs were significantly increased in DM + UAP group. Conclusions Our study suggested that increases in the fractalkine level and the number and functional changes of blood DCs might contribute to diabetic coronary atherosclerosis and plaque destabilization.

    Unstable angina(UA) is the most dangerous type of Coronary Heart Disease(CHD) to cause more and more mortal and morbid world wide. Identification of biomarkers for UA at the level of proteomics and metaboiomics is a better avenue to understand the inner mechanism of it. Feature selection based data mining method is better suited to identify biomarkers of UA. In this study, we carried out clinical epidemiology to collect plasmas of UA in-patients and controls. Proteomics and metabolomics data were obtained via two-dimensional difference gel electrophoresis and gas chromatography techniques. We presented a novel computational strategy to select biomarkers as few as possible for UA in the two groups of data. Firstly, decision tree was used to select biomarkers for UA and 3-fold cross validation was used to evaluate computational performances for the three methods. Alternatively, we combined independent t test and classification based data mining method as well as backward elimination technique to select, as few as possible, protein and metabolite biomarkers with best classification performances. By the method, we selected 6 proteins and 5 metabolites for UA. The novel method presented here provides a better insight into the pathology of a disease.

    Group dancing is a ubiquitous human activity that involves exertive synchronized movement to music. It is hypothesized to play a role in social bonding, potentially via the release of endorphins, which are analgesic and reward-inducing, and have been implicated in primate social bonding. We used a 2 × 2 experimental design to examine effects of exertion and synchrony on bonding. Both demonstrated significant independent positive effects on pain threshold (a proxy for endorphin activation) and in-group bonding. This suggests that dance which involves both exertive and synchronized movement may be an effective group bonding activity. PMID:26510676

    Introduction Little is known about the prevalence and predictors of chronic non-communicable diseases (NCDs) of older adults in South Africa. This study aims to investigate the self-reported prevalences of major chronic NCDs and their predictors among older South Africans. Methods We conducted a national population-based cross-sectional survey with a sample of 3,840 individuals aged 50 years or above in South Africa in 2008. The outcome variable was the self-reported presence of chronic NCDs suffered, namely, arthritis, stroke, angina, diabetes, chronic lung disease, asthma, depression, and hypertension. The exposure variables were sociodemographic characteristics: age, gender, education, wealth status, race, marital status, and residence. Multivariate logistic regression was used to determine sociodemographic factors predictive of the presence of chronic NCDs. Results The prevalence of chronic NCDs was 51.8%.

    Full Text Available Introduction: Little is known about the prevalence and predictors of chronic non-communicable diseases (NCDs of older adults in South Africa. This study aims to investigate the self-reported prevalences of major chronic NCDs and their predictors among older South Africans. Methods: We conducted a national population-based cross-sectional survey with a sample of 3,840 individuals aged 50 years or above in South Africa in 2008. The outcome variable was the self-reported presence of chronic NCDs suffered, namely, arthritis, stroke, angina, diabetes, chronic lung disease, asthma, depression, and hypertension. The exposure variables were sociodemographic characteristics: age, gender, education, wealth status, race, marital status, and residence. Multivariate logistic regression was used to determine sociodemographic factors predictive of the presence of chronic NCDs. Results: The prevalence of chronic NCDs was 51.8%. The prevalence of multimorbidity (≥2 chronic conditions was 22.5%. Multivariate logistic regression analysis showed that being female, being in age groups 60–79 and 70–79, being Coloured or Asian, having no schooling, having greater wealth, and residing in an urban area were associated with the presence of NCDs. Conclusion: The rising burden of chronic NCDs affecting older people places a heavy burden on the healthcare system as a result of increased demand and access to healthcare services. Concerted effort is needed to develop strategies for the prevention and management of NCDs, especially among economically disadvantaged individuals who need these services the most.

    Pulmonary arterial hypertension (PAH) is a chronic disease which causes overload to the right ventricle. The effect of preventive training on cardiac remodelling in this condition is still unknown. This study aimed to evaluate the influence of preventive training on hypertrophy, heart function and gene expression of calcium transport proteins in rats with monocrotaline-induced PAH. Thirty-two male Wistar rats were randomly divided into four groups: S, sedentary control; T, trained control; SM, sedentary monocrotaline; and TM, trained monocrotaline. The preventive training protocol was performed on a treadmill for 13 weeks, five times/week. The first two weeks were adopted for adaptation to training with gradual increases in speed/time. The speed of the physical training from the third to tenth weeks was gradually increased from 0.9 to 1.1 km/h for 60 min. Next, monocrotaline was applied (60 mg/kg) to induce PAH and lactate threshold analysis performed to determine the training speeds. The training speed of the TM group in the following two weeks was 0.8 km/h for 60 min and the T = 0.9 km/h for 60 min; in the final two weeks, both groups trained at the same speed and duration 0.9 km/h, 60 min. Cardiac function was assessed through echocardiography, ventricular hypertrophy through histomorphometric analysis and gene expression through RT-qPCR. Right cardiac function assessed through the peak flow velocity was SM = 75.5 cm/s vs. TM = 92.0 cm/s (P = 0.001), and ventricular hypertrophy was SM = 106.4 μm² vs. TM = 77.7 μm² (P = 0.004). There was a decrease in the gene expression of ryanodine S = 1.12 au vs. SM = 0.60 au (P = 0.02) without alterations due to training. Thus, we conclude that prior physical training exerts a cardioprotective effect on the right ventricle in the monocrotaline rat model. PMID:27365256

    The relation between exercise test, echocardiography and clinical course of acute myocardial infarction was investigated. 17-34 days after an acute myocardial infarction, before hospital discharge, 58 patients underwent exercise test and 17-28 days- echocardiography. Low exercise capacity was significant related to angina before infarction, maximal CKNAC and complications during clinical course. There was inverted correlation of asynergy index calculated from echocardiography with maximal workload achieved during exercise test.

    BACKGROUND: High physical exertion during work is a risk factor for musculoskeletal pain and long-term sickness absence. Physical exertion (RPE) reflects the balance between physical work demands and physical capacity of the individual. Thus, increasing the physical capacity through physical...... exercise may decrease physical exertion during work. This study investigates the effect of workplace-based versus home-based physical exercise on physical exertion during work (WRPE) among healthcare workers. METHODS: 200 female healthcare workers (age: 42.0, body mass index: 24.1, average pain intensity......: 3.1 on a scale of 0 to 10, average WRPE: 3.6 on a scale of 0 to 10) from 18 departments at three participating hospitals. Participants were randomly allocated at the cluster level to 10 weeks of: (1) workplace physical exercise (WORK) performed in groups during working hours for 5×10 minutes per...

    Group dancing is a ubiquitous human activity that involves exertive synchronized movement to music. It is hypothesized to play a role in social bonding, potentially via the release of endorphins, which are analgesic and reward-inducing, and have been implicated in primate social bonding. We used a 2 × 2 experimental design to examine effects of exertion and synchrony on bonding. Both demonstrated significant independent positive effects on pain threshold (a proxy for endorphin activation) and...

    Full Text Available Objective. We tested the association of specific psychological characteristics in patients having stable coronary disease with the reporting of anginal symptoms during daily activities, and positive exercise testing. Methods. One hundred and ninety-six patients with documented CAD enrolled in the Psychophysiological Investigations of Myocardial Ischemia (PIMI Study completed an anginal history questionnaire and a battery of psychometric tests. They also underwent standardized exercise treadmill tests. Results. Patients with a recent history of angina were more likely to be female, and had higher Beck Depression (P=.002, State Anxiety (P=.001, Trait Anxiety (P=.03, Harm Avoidance (P=.04 and Muscle Tension (P=.004 scores than patients who had no recent history of angina. Along with several treadmill variables indicating more severe disease state and reduced exercise tolerance, patients who developed angina on a positive treadmill test also displayed higher scores on the Beck Depression Inventory (P=.003 and State Anxiety (P=.004 scales. Conclusions. Several psychological characteristics, and most notably anxiety and depression, are strong correlates of recent angina and angina in the presence of ischemia provoked by treadmill testing.

    Objective To observe the relationship between serum creatine kinase isoenzyme MM sub-bands (CKMM3/MM1 ratio) and the gradation of coronary stenosis and provide a simple, reliable, and economical method for identifying high-risk unstable angina pectoris (UAP). Mehtods Blood samples were drawn at different time after onset of chest pain in 21 patients with UAP and only once in 20 each volunteers for control. CKMM3/MM1 ratio was detected by nonserial buffer agarose gel electrophoresis. CKMB and CK were observed by velocity method. An emergent coronary arteriography was performed as soon as patients were admitted into hospital. Results Patients with UAP were divided into two subgroups:patients with elevated serum enzyme [P( + )] and patients with normal serum enzyme [P( - ) ] according to CKMM3/MM1 ratio < 0.5. Patients with UAP(+)had higher serum CKMM3/MM1 ratios from 0.5 to 12hrs and serum CKMB from 2 to 12 hrs than those with UAP( - ) and control ( P < 0.05) . Serum enzyme concentrations of patients with UAP whose coronary lumen had 90% or more than 90% stenosis were significantly higher than those whose coronary lumen had less than 90% stenosis (P<0.01) . AnyCKMM3/MM1 ratio was less than 1.0 and CK within the normal range in patients with UAP( + ) group. Conclusions CKMM3/MM1 ratios in patients with UAP can reflect severity of myocardial ischemia. Serum CKMM3/MM1 ratio provides a simple, reliable, and economical method for identifying high-risk UAP.

    A gastrointestinal therapeutic system (GITS) of nifedipine has been developed to provide a once-daily dosing, and predictable, relatively constant plasma concentrations. This study compared the antianginal efficacy of nifedipine GITS with a once-a-day beta-receptor blocker, atenolol. Seventeen patients with documented coronary artery disease and stable stress-induced angina pectoris were studied during a 2-week, single-blind, placebo baseline phase and a 12-week randomized, double-blind, active drug crossover efficacy phase, using the bicycle exercise test and ambulatory electrocardiographic recordings. Patients exercised significantly longer with nifedipine GITS (883 +/- 47 seconds) and atenolol (908 +/- 44 seconds) than with placebo (794 +/- 41 seconds). Nifedipine GITS reduced systolic blood pressure at all stages of exercise compared with placebo but, because heart rate tended to increase more during nifedipine therapy, there was no difference in rate-pressure products between the placebo and nifedipine GITS periods. In contrast, atenolol reduced heart rate, systolic blood pressure and rate-pressure product during exercise compared with placebo. Whereas left ventricular ejection fractions (by radionuclide angiocardiography) increased with exercise, the maximal increase was smaller with atenolol than with placebo and nifedipine. The net increase in left ventricular ejection fraction at the end of exercise was greater with nifedipine than with placebo or atenolol. Ambulatory electrocardiograms showed only a small number of ischemic events. Neither nifedipine GITS nor atenolol reduced the number of ischemic events or total duration of ST-segment deviations significantly. It is concluded that nifedipine GITS is as effective an antianginal agent as atenolol, but the hemodynamic effects of the 2 agents differ.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8279372

    Full Text Available BACKGROUND: The presence of pre-infarction angina (PIA has been shown to confer cardioprotection after ST-segment elevation myocardial infarction (STEMI. However, the clinical impact of PIA in non-ST-segment elevation myocardial infarction (NSTEMI remains to be determined. METHODS AND RESULTS: From the obseRvatoire des Infarctus de Côte d'Or (RICO survey, 1541 consecutive patients admitted in intensive care unit with a first NSTEMI were included. Patients who experienced chest pain <7 days before the episode leading to admission were defined as having PIA and were compared with patients without PIA. Incidence of in-hospital ventricular arrhythmias (VAs, heart failure and 30-day mortality were collected. Among the 1541 patients included in the study, 693 (45% patients presented PIA. PIA was associated with a lower creatine kinase peak, as a reflection of infarct size (231(109-520 vs. 322(148-844 IU/L, p<0.001 when compared with the group without PIA. Patients with PIA developed fewer VAs, by 3 fold (1.6% vs. 4.0%, p = 0.008 and heart failure (18.0% vs. 22.4%, p = 0.040 during the hospital stay. Overall, there was a decrease in early CV events by 26% in patients with PIA (19.2% vs. 25.9%, p = 0.002. By multivariate analysis, PIA remained independently associated with less VAs. CONCLUSION: From this large contemporary prospective study, our work showed that PIA is very frequent in patients admitted for a first NSTEMI, and is associated with a better prognosis, including reduced infarct size and in hospital VAs. Accordingly, protecting the myocardium by ischemic or pharmacological conditioning not only in STEMI, but in all type of MI merits further attention.

    Highlights: • Patients developing UAP had overall more atherosclerosis as patients without any events. • Patients developing MACE had only more mixed plaque as those developing UAP. • Different atherosclerotic plaque components by CTA carry different prognostic value. - Abstract: Objective: CT angiography (CTA) has prognostic value in patients. But it is unknown whether differences in atherosclerosis by CTA predict the development of unstable angina pectoris (UAP) vs. major adverse cardiac events (MACE). Methods: We followed patients undergoing CTA as part of their acute chest pain work-up. Primary outcome was the development of UAP or MACE (cardiac death, myocardial infarction, revascularization) during a minimum follow-up of 12-months. CTAs were assessed for extent and composition of coronary plaque and stenosis. Ordinal regression with a 3-level outcome (no events, UAP, MACE) was applied. Results: Among 315 patients, 22 developed UAP and 31 MACE. While UAP patients had higher atherosclerosis burden with respect to all assessed features compared to patients with no events (p ≤ 0.02), only mixed plaque extent was significantly different between UAP and MACE patients (p = 0.02). The odds ratio was 4.55 for being in a higher disease-level comparing patients with low extent to those with no mixed plaque, and 3.02 comparing patients with high to those with low. These findings remained after adjustments for potential confounders. Conclusion: The extent of mixed coronary plaque is different between patients who develop UAP vs. MACE, supporting the hypothesis that it is a more culprit morphology.

    This study investigated retardation of abnormal uptake of iodine-123-beta-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) scintigraphy in patients with vasospastic angina. Twenty-three patients with vasospastic angina showed abnormal uptake of BMIPP before medical treatment and had coronary vasospasm induced by acetylcholine. The patients were divided into two groups according to uptake of BMIPP after medical treatment: retardation of abnormal uptake of BMIPP (Group R, n=4) and normal uptake of BMIPP (Group N, n=19). Frequency of chest pain, medical treatment and autonomic nervous activity were compared between the two groups. Furthermore, the frequency of chest pain and uptake of BMIPP in group R were obtained after intensive medical treatment. Autonomic nervous activity was evaluated by heart rate variability on Holter electrocardiography. Heart rate variability contained high-frequency elements (HF; 0.15-0.4 Hz) and low-frequency elements (LF; 0.04-0.15 Hz). LF/HF was estimated for sympathetic nervous activity and HF was estimated for parasympathetic nervous activity. Daytime and nighttime autonomic nervous activity were compared between the two groups. The frequency of chest pain was higher in Group R than in Group N (p<0.05). Medical treatment was not different between the two groups. Circadian variation of sympathetic and parasympathetic nervous activity were absent in Group R. During the nighttime, Group R showed higher sympathetic nervous activity (p<0.05) and lower parasympathetic nervous activity (p<0.01) than Group N. The frequency of chest pain was significantly lower after intensive medical treatment (p<0.05), and uptake of BMIPP returned to normal in Group R. We suspected that the disorder in autonomic nervous activity was more severe in Group R, and thus induced coronary vasospasm. Retardation of abnormal uptake of BMIPP in patients with vasospastic angina indicates poor control of coronary vasospasm. Uptake of BMIPP is useful in the evaluation of

    Objectives In addition to its lipid-lowering properties, statin decreases the level of C-reactive protein (CRP) resulting in reduction of cardiovascular events. However, information about discontinuation of statin therapy in stable cardiac patients is limited. This was a prospective cohort study to explore whether withdrawal of statin treatment could result in rebound of inflammation in patients with stable angina pectoris in a short-term course.Methods and Results 75 patients with stable angina pectoris were randomly divided into three groups: ① Pretreatment with Xuezhikang (XZK, an extract of cholestin) for 6 weeks and then replaced by placebo; ②Treatment with XZK throughout the study; ③ Placebo. Lipid levels, highly sensitive CRP (hs-CRP) and serum cardiac troponin T (cTnT) were assessed before receiving the XZK therapy, 1 day before discontinuation of XZK, and on day 1, 2, 3,7 and 14 after discontinuation of XZK, respectively.At day 14 after discontinuation of XZK therapy,total cholesterol, LDL-C and triglyceride significantly increased, whereas HDL-C level significantly decreased. The median level of hs-CRP increased significantly from the second day after withdrawal of XZK therapy. There was a prominent rebound of hs-CRP concentration 3 days after discontinuation of XZK therapy. 7 to 14 days after discontinuation of XZK therapy, the hs-CRP concentration declined to a similar level as in the placebo group. Elevated cTnT level did not occur throughout the study course in either group. Conclusions Short-term discontinuation of statin therapy could induce a rapid rebound phenomenon of inflammatory response independently of changes of lipid parameters. However, it was not enough to induce myocardial injury in this cohort of patients with stable angina pectoris.

    Full Text Available Abstract Background In Australia there is a socioeconomic gradient in morbidity and mortality favouring socioeconomically advantaged people, much of which is accounted for by ischaemic heart disease. This study examines if Australia's universal health care system, with its mixed public/private funding and delivery model, may actually perpetuate this inequity. We do this by quantifying and comparing socioeconomic inequalities in the receipt of coronary procedures in patients with acute myocardial infarction (AMI and patients with angina. Methods Using linked hospital and mortality data, we followed patients admitted to Western Australian hospitals with a first admission for AMI (n = 5539 or angina (n = 7401 in 2001-2003. An outcome event was the receipt, within a year, of a coronary procedure—angiography, angioplasty and/or coronary artery bypass surgery (CABG. Socioeconomic status was assigned to each individual using an area-based measure, the SEIFA Index of Disadvantage. Multivariable proportional hazards regression was used to model the association between socioeconomic status and procedure rates, allowing for censoring and adjustment of multiple covariates. Mediating models examined the effect of private health insurance. Results In the AMI patient cohort, socioeconomic gradients were not evident except that disadvantaged women were more likely than advantaged women to undergo CABG. In contrast, in the angina patient group there were clear socioeconomic gradients for all procedures, favouring more advantaged patients. Compared with patients in the most disadvantaged quintile of socioeconomic status, patients in the least disadvantaged quintile were 11% (1-21% more likely to receive angiography, 52% (29-80% more likely to undergo angioplasty and 30% (3-55% more likely to undergo CABG. Private health insurance explained some of the socioeconomic variation in rates. Conclusions Australia's universal health care system does not guarantee

    Full Text Available Introduction Inadequately controlled chronic diseases may present a threat to life and well-being during the emergency response to natural disasters. An estimate of the possible numbers of people who may require treatment for chronic diseases should help in planning a response, but such information for local areas is not easily accessible. We explored how a current surveillance system could be used to provide estimates of the potential needs for emergency treatment of chronic diseases in the wake of a natural disaster. Methods We used data from adults aged 18 years or older who participated in the Behavioral Risk Factor Surveillance System (BRFSS in 2004 to estimate the prevalence and numbers of people with diabetes, heart disease, stroke, hypertension, and current asthma who lived in the New Orleans–Metairie–Kenner, La, metropolitan statistical area. Results About 9.0% of participants had diabetes, 4.6% had angina or coronary heart disease, 3.0% had had a myocardial infarction, 2.0% had had a stroke, and 6.3% had current asthma. About 25.4% adults had at least one of the above conditions. Conclusion A surveillance system such as the BRFSS can provide potentially useful baseline information about the numbers of people with chronic diseases and the treatment that they receive; this information can assist the medical and public health community in assessing the needs of people with chronic diseases after disasters and in planning relief efforts.

    Relationships between perceived exertion and blood lactate have usually been studied in laboratory or training contexts but not in competition, the most important setting in which sports performance is evaluated. The purpose of this study was to examine the relationships between psychological and physiological indices of the physical effort in a competition setting, taking into account the duration of effort. For this, we employed two Ratings of Perceived Exertion (RPE and CR-10) and lactic acid plasma concentration as a biological marker of the effort performed. 13 male judo fighters who participated in a sports club competition provided capillary blood samples to assay lactate concentrations and indicated on scale their Recall of Perceived Exertion in the total competition and again in just the Last Fight to compare the usefulness of RPE and CR-10 in assessing discrete bouts of effort and a whole session. Analysis showed that perceived exertion or the effort made during the whole competition was positively and significantly related to maximal lactate concentration and lactate increase in competition, thus extending the validity of this scale to sports contests. The Recall of Perceived Exertion scores were not significantly correlated with the duration of effort.

    The purpose of this study was to assess the effect of sprint interval training on rating of perceived exertion. 20 healthy participants (11 men, 9 women; M age = 23 yr.) completed a maximal cycle ergometer test and two high-intensity interval training cycling sessions. Each session utilized the same work-to-rest ratio (1:1), work intensity (90% max), recovery intensity (10% work intensity), and session duration (16 min.). Trials differed on duration of the interval segment, with a 30-sec. trial and a 60-sec. trial. Sessions required the same amount of total work over the duration of the trial. Rating of perceived exertion assessed before, during, and after exercise were higher for the 60-sec. trial than the 30-sec. trial despite no difference in total work. High intensity interval training trials utilizing the same total external work but differing in interval length produced different ratings of perceived exertion. Perceived exertion is significantly higher for sessions of exercise that utilize longer work intervals. These findings suggest that shorter intervals may produce more favorable exertional responses that could positively affect future behavior.

  13. Acute and chronic arsenic toxicity.

    2003-07-01

    Arsenic toxicity is a global health problem affecting many millions of people. Contamination is caused by arsenic from natural geological sources leaching into aquifers, contaminating drinking water and may also occur from mining and other industrial processes. Arsenic is present as a contaminant in many traditional remedies. Arsenic trioxide is now used to treat acute promyelocytic leukaemia. Absorption occurs predominantly from ingestion from the small intestine, though minimal absorption occurs from skin contact and inhalation. Arsenic exerts its toxicity by inactivating up to 200 enzymes, especially those involved in cellular energy pathways and DNA synthesis and repair. Acute arsenic poisoning is associated initially with nausea, vomiting, abdominal pain, and severe diarrhoea. Encephalopathy and peripheral neuropathy are reported. Chronic arsenic toxicity results in multisystem disease. Arsenic is a well documented human carcinogen affecting numerous organs. There are no evidence based treatment regimens to treat chronic arsenic poisoning but antioxidants have been advocated, though benefit is not proven. The focus of management is to reduce arsenic ingestion from drinking water and there is increasing emphasis on using alternative supplies of water.

  14. Matrix stiffness exerts biphasic control over monocyte-endothelial adhesion via Rho-mediated ICAM-1 clustering.

    Leukocyte-endothelial adhesion is a critical early step in chronic vascular inflammation associated with diabetes, emphysema, and aging. Importantly, these conditions are also marked by abnormal subendothelial matrix crosslinking (stiffness). Yet, whether and how abnormal matrix stiffness contributes to leukocyte-endothelial adhesion remains poorly understood. Using a co-culture of human monocytic cells and human microvascular endothelial cells (ECs) grown on matrices of tunable stiffness, we demonstrate that matrix stiffness exerts biphasic control over monocyte-EC adhesion, with both matrix softening and stiffening eliciting a two-fold increase in this adhesive interaction. This preferential endothelial adhesivity on softer and stiffer matrices was consistent with a significant increase in α-actinin-4-associated endothelial ICAM-1 clustering, a key determinant of monocyte-EC adhesion. Further, the enhanced ICAM-1 clustering on soft and stiff matrices correlated strongly with an increase in Rho activity and ROCK2 expression. Importantly, inhibition of Rho/ROCK activity blocked the effects of abnormal matrix stiffness on ICAM-1 clustering and monocyte-EC adhesion. Thus, these findings implicate matrix stiffness-dependent ICAM-1 clustering as an important regulator of vascular inflammation and provide the rationale for closely examining mechanotransduction pathways as new molecular targets for anti-inflammatory therapy.

    Objective To investigate the therapeutic effect of Tiaozhi Decoction for the treatment of coronary heart disease induced stable angina complicated with hyperlipemia, and to observe its effect on serum inflammatory factors. Results One hundred qualified patients were evenly randomized into treatment group and control group. Both groups were given conventional western medical treatment with reference to Guide for Diagnosis and Treatment of Chronic Stable Angina, and additionally, the control group was given oral use of Simvastatin and the treatment group was given Tiaozhi Decoction orally. The treatment of the two groups covered 8 weeks. Before and after treatment, blood lipid levels of total cholesterol ( TC) , triglyceride ( TG) , low-density lipoprotein cholesterol ( LDL-C) , high- density lipoprotein cholesterol ( HDL-C) , apolipoprotein A (ApoA) and apolipoprotein B (ApoB) were observed. The frequency of angina pectoris attack and the dosage of Nitroglycerin Tablets per week in both groups were recorded during the treatment. Therapeutic effect on lowering blood lipid and on improving electrocardiogram was evaluated after treatment. Serum levels of hypersensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), homocysteic acid (Hcy), adiponectin (APN), and oxidized low-density lipoprotein (ox-LDL) were detected before and after treatment. Results(1) The results of Ridit analysis showed that the treatment group had better therapeutic effect on lowering blood lipid and on improving electrocardiogram than the control group ( P<0.05) . ( 2) After treatment, TG, HDL-C, ApoB and ApoA levels were much improved in the treatment group compared with those in the control group (P<0.01) . ( 3) The frequency of angina pectoris attack and the dosage of Nitroglycerin Tablets per week were reduced in the treatment group compared with those in the control group (P<0.01) . (4) After treatment, the treatment group had lower hs-CRP, IL-6, Hcy and ox-LDL levels, and higher APN

    A fast full-wave method for computing radiation pressure force (RPF) exerted by shaped light beams on moving particles is presented. The problem of evaluating RPF exerted on a moving particle by a single excitation beam is converted into that of computing RPF's exerted on a static particle by multiple beams. The discretization of different beams leads to distinct right hand sides (RHS's) for the matrix system. To avoid solving each RHS by the brute-force manner, the algorithm conducts low-rank decomposition on the excitation matrix consisting of all RHS's to figure out the so-called skeleton light beams by interpolative decomposition (ID). The peak memory requirement of the skeletonization is a bottle-neck if the particle is large. A two-level skeletonization scheme is proposed to solve this problem. Some numerical experiments on arbitrarily shaped homogeneous particles are performed to illustrate the performance and capability of the developed method. PMID:24787885

    Acute liver failure is defined as rapid loss of liver function that patients without previously recognized liver disease sustain a liver damage. Acute liver failure due to non-exertional heatstroke has rarely been reported. We reported here an unusual case of heat stroke induced acute liver failure (ALF) after sauna. A 63 year old man without previously recognized liver and other systemic disease was admitted for loss of consciousness and impaired liver function after sauna. Despite intensive supportive care, ALF developed. Liver transplantation was planned but the patient died on the sixth day of hospitalization. Non-exertional heatstroke induced ALF is a rare and serious condition. ALF caused by non-exertional heatstroke which requires liver transplantation for definitive solution should be kept in mind in early period.

    Full Text Available Chronic urticaria (CU is a disturbing allergic condition of the skin. Although frequently benign, it may sometimes be a red flag sign of a serious internal disease. A multitude of etiologies have been implicated in the causation of CU, including physical, infective, vasculitic, psychological and idiopathic. An autoimmune basis of most of the ′idiopathic′ forms is now hypothesized. Histamine released from mast cells is the major effector in pathogenesis and it is clinically characterized by wheals that have a tendency to recur. Laboratory investigations aimed at a specific etiology are not always conclusive, though may be suggestive of an underlying condition. A clinical search for associated systemic disease is strongly advocated under appropriate circumstances. The mainstay of treatment remains H1 antihistaminics. These may be combined with complementary pharmacopeia in the form of H2 blockers, doxepin, nifedipine and leukotriene inhibitors. More radical therapy in the form of immunoglobulins, plasmapheresis and cyclophosphamide may be required for recalcitrant cases. Autologous transfusion and alternative remedies like acupuncture have prospects for future. A stepwise management results in favorable outcomes. An update on CU based on our experience with patients at a tertiary care centre is presented.

  20. Effects of fitness and self-confidence on time perception during exertion

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Aims: Human physical and psychological features influence perceptions of the environment during activity. If during exercise an individual over-estimates time, they may interpret this as spending longer than necessary under a potentially aversive state of exertion. This may in turn decrease one’s sense of exercise success and tendency to persevere with exercise. We tested if experimentally manipulating sense of exercise self-efficacy would affect time perception during standardised physical exertion. Method: Exercise Self-Efficacy (ESE of 18 -73 year olds (N=51 was measured before and after an exercise challenge of moderate intensity. Height, weight and body fat composition were measured before participants were randomly allocated to one of three groups. After a 4-minute treadmill fitness test, participants were presented with either bogus feedback about their performance (positive or negative or no feedback (control. Before and during exercise, participants estimated a prescribed 2-minute time interval. Ratings of perceived exertion were also measured periodically. Results: Feedback on performance had no significant effect on time perception, even when controlling for individual exertion level. Reported ESE was also unaffected by whether someone received positive, negative or no feedback. Age was again found to be significantly correlated with VO2max, r(51 = .62, p < .001, but in contrast to prior findings, estimates of general fitness such as VO2max, BMI and waist circumference were unrelated to changes in time perception due to exertion. Conclusions: These findings failed to support prior findings and anecdotal evidence suggesting that exertion might alter one’s perception of time. We also failed to find any support for effects on ESE when participants were given explicit performance feedback. Finally, participants’ physical characteristics appear to be unrelated to time perception whilst exercising at moderate intensity.

    The job related reintegration of patients with coronary artery disease (CAD) is a central part of cardiac rehabilitation. However, specific occupational demands like jobs with heavy physical exertion (> 6 METs) could increase the cardiovascular risk because the relative risk for acute myocardial infarction (MI) and cardiac death is temporarily elevated after vigorous exertion ("hazard period"). Thus, in 2001 any male patient with proven CAD who performed a job with heavy exertion until the occurrence of an index event (MI/ACS, any interventional or surgical revascularization measure) received a questionnaire after an average of 20 months. Complete data were available in 108 from 119 included patients (90.8%), aged 51.8+/-7.8 years. Ejection fraction was 61.5+/-13.1% and the functional capacity at the time of hospital discharge averaged 130.1+/-31.2 W. 75% of the patients had a previous MI and 59.3% underwent bypass surgery. During follow-up the previous job with heavy exertion was performed over a cumulated time of 74 years. The aim of the study was to compare the observed and the expected incidence of MI and cardiac death with and without job performance. The expected ("basal") risk for MI and cardiac death without heavy physical exertion was determined from pooled study results and assumed to be 5.2% per year. The combined risk due to performing an occupation with strenuous exertion can be calculated from time periods with and without working hours and amounts to 11.9%. There could be expected 0.119 . 74=8.8 cardiac events related to the job. In contrast, 5 MIs (4 NSTEMI, 1 STEMI) were observed (6.8%). The relative risk for an expected event compared to the basal risk without heavy exertion was 2.3 (95% CI: 0.7-7.4). The relative risk for the observed cardiac events amounts to 1.3 (95% CI: 0.4-4.8). The lower observed risk is probably due to the high grade of physical fitness in this patient group. In spite of several limitations, our study showed no convincing

We were interested in the association between doubling of serum creatinine and the risk of a first-time diagnosis of angina pectoris, congestive heart failure (CHF, myocardial infarction (MI, stroke, or transient ischemic attack in patients with chronic kidney disease and with diagnosed type 2 diabetes mellitus. Methods: We identified all adult patients registered in the “Clinical Practice Research Datalink” between 2002 and 2011 with incident chronic kidney disease and type 2 diabetes mellitus and did a cohort study with a Cox proportional hazard analysis. Results: We identified in total 27,811 patients, 693 developed angina pectoris, 1,069 CHF, 508 MI, 970 stroke, and 578 transient ischemic attacks. Patients whose serum creatinine doubled during follow-up had increased risks of CHF (hazard ratio [HR] 2.98, 95% confidence interval [CI] 2.27–3.89, MI (HR 2.53, 95% CI 1.62–3.96, and stroke (HR 1.93, 95% CI 1.38–2.69, as compared with patients whose serum creatinine did not double. The relative risks of angina pectoris (HR 1.18, 95% CI 0.66–2.10 or a transient ischemic attack (HR 1.32, 95% CI 0.78–2.22 were similar in both groups. Conclusion: Diabetic patients with a doubling of serum creatinine were at an increased risk of CHF, MI, or stroke, compared with diabetic

    Full Text Available Data on the association between chronic conditions or the number of chronic conditions and sleep problems in low- or middle-income countries is scarce, and global comparisons of these associations with high-income countries have not been conducted.Data on 42116 individuals 50 years and older from nationally-representative samples of the Collaborative Research on Ageing in Europe (Finland, Poland, Spain and the World Health Organization's Study on Global Ageing and Adult Health (China, Ghana, India, Mexico, Russia, South Africa conducted between 2011-2012 and 2007-2010 respectively were analyzed.The association between nine chronic conditions (angina, arthritis, asthma, chronic lung disease, depression, diabetes, hypertension, obesity, and stroke and self-reported severe/extreme sleep problems in the past 30 days was estimated by logistic regression with multiple variables. The age-adjusted prevalence of sleep problems ranged from 2.8% (China to 17.0% (Poland. After adjustment for confounders, angina (OR 1.75-2.78, arthritis (OR 1.39-2.46, and depression (OR 1.75-5.12 were significantly associated with sleep problems in the majority or all of the countries. Sleep problems were also significantly associated with: asthma in Finland, Spain, and India; chronic lung disease in Poland, Spain, Ghana, and South Africa; diabetes in India; and stroke in China, Ghana, and India. A linear dose-dependent relationship between the number of chronic conditions and sleep problems was observed in all countries. Compared to no chronic conditions, the OR (95%CI for 1,2,3, and ≥ 4 chronic conditions was 1.41 (1.09-1.82, 2.55 (1.99-3.27, 3.22 (2.52-4.11, and 7.62 (5.88-9.87 respectively in the overall sample.Identifying co-existing sleep problems among patients with chronic conditions and treating them simultaneously may lead to better treatment outcome. Clinicians should be aware of the high risk for sleep problems among patients with multimorbidity. Future studies

    Past research indicates that peoples' implicit theories about the nature of willpower moderate the ego-depletion effect. Only people who believe or were led to believe that willpower is a limited resource (limited-resource theory) showed lower self-control performance after an initial demanding task. As of yet, the underlying processes explaining this moderating effect by theories about willpower remain unknown. Here, we propose that the exertion of self-control activates the goal to preserve and replenish mental resources (rest goal) in people with a limited-resource theory. Five studies tested this hypothesis. In Study 1, individual differences in implicit theories about willpower predicted increased accessibility of a rest goal after self-control exertion. Furthermore, measured (Study 2) and manipulated (Study 3) willpower theories predicted an increased preference for rest-conducive objects. Finally, Studies 4 and 5 provide evidence that theories about willpower predict actual resting behavior: In Study 4, participants who held a limited-resource theory took a longer break following self-control exertion than participants with a nonlimited-resource theory. Longer resting time predicted decreased rest goal accessibility afterward. In Study 5, participants with an induced limited-resource theory sat longer on chairs in an ostensible product-testing task when they had engaged in a task requiring self-control beforehand. This research provides consistent support for a motivational shift toward rest after self-control exertion in people holding a limited-resource theory about willpower. PMID:26075793

    Full Text Available We assessed the cardiorespiratory and immune response to physical exertion following secondhand smoke (SHS exposure through a randomized crossover experiment. Data were obtained from 16 (8 women non-smoking adults during and following a maximal oxygen uptake cycling protocol administered at baseline and at 0-, 1-, and 3- hours following 1-hour of SHS set at bar/restaurant carbon monoxide levels. We found that SHS was associated with a 12% decrease in maximum power output, an 8.2% reduction in maximal oxygen consumption, a 6% increase in perceived exertion, and a 6.7% decrease in time to exhaustion (P<0.05. Moreover, at 0-hours almost all respiratory and immune variables measured were adversely affected (P<0.05. For instance, FEV(1 values at 0-hours dropped by 17.4%, while TNF-α increased by 90.1% (P<0.05. At 3-hours mean values of cotinine, perceived exertion and recovery systolic blood pressure in both sexes, IL4, TNF-α and IFN-γ in men, as well as FEV(1/FVC, percent predicted FEV(1, respiratory rate, and tidal volume in women remained different compared to baseline (P<0.05. It is concluded that a 1-hour of SHS at bar/restaurant levels adversely affects the cardiorespiratory and immune response to maximal physical exertion in healthy nonsmokers for at least three hours following SHS.

    The aims of this study were to establish the cardiovascular and metabolic demands of a university step aerobics session entitled 'Uni-Step' performed at three step heights, and to evaluate the use of heart rate and ratings of perceived exertion for the estimation of exercise intensity during this mode. Ten female participants in step aerobics (mean VO2max = 47.7, s = 6.8 ml.kg-1.min-1) performed a 40-min Uni-Step routine on steps of height 6, 8 and 10 inches (15.2, 20.3 and 25.4 cm). Oxygen uptake, heart rate and ratings of perceived exertion were recorded throughout each test. Maximum oxygen uptake (VO2max) and maximum heart rate were measured using a continuous treadmill protocol. The mean intensities were 45.6%, 51.6% and 56.2% VO2max for the 6-, 8- and 10-inch steps respectively. The mean percent heart rate reserves were 57.2%, 63.6% and 70.1% at these three heights respectively. Correlations indicated a weak relationship between %VO2max and ratings of perceived exertion for the 6- and 8-inch steps (r = 0.61 and 0.66 respectively) but a stronger one for the 10-inch step (r = 0.79). Uni-Step performed on the two highest steps was of a sufficient relative intensity to improve or maintain the cardiovascular fitness of participants in this study. The lowest step may be useful for participants of lower fitness. Heart rate overestimated the metabolic cost of Uni-Step at all three step heights and therefore caution is advised if used to predict intensity. Low correlations between %VO2max and ratings of perceived exertion at the two lower step heights indicate that ratings of perceived exertion may have limited utility in prescribing training intensity.

    Background It is unclear whether edge segments have different responses to paclitaxel eluting stent (PES) and sirolimus eluting stent (SES) implantation in patients with unstable angina. This study aimed to compare the different vascular edge responses in patients with unstable angina and single de novo coronary lesion treated with SES and PES. Methods Two hundred and fifty-five patients with unstable angina and single de novo lesion were randomly assigned to PES and SES groups. Serial volumetric intravascular ultrasound (IVUS) images were taken immediately after stenting and at an eight-month follow-up. Five-mm edge segments proximal and distal to the stents were analyzed. Results Baseline characteristics were comparable between the two groups. At proximal-edge segment, the vessel area decreased and the plaque area increased significantly in the PES group as compared with the SES group. A significant net loss of lumen area was found in the PES group (from (11.10±3.12) mm2 at baseline to (9.92+3.59) mm2 at the follow-up, P <0.001). At the distal-edge segment, the net loss of lumen area in the PES group (from (7.71±2.81) mm2 at baseline to (6.66±2.29) mm2 at the follow-up, P <0.001) was attributed to a significant increase of plaque area. Proximal-edge stenosis was commonly seen in the PES group (20.0%) as compared with the SES group (5.0%, P=0.001). This correlated with the higher incidence of target lesion revascularization in the PES group (P=-0.03). Subsegmentally, the smallest A lumen area was located at 2 mm proximally in both groups, at 0 mm distally in the PES group, and at 1 mm distally in the SES group. Conclusions The two groups demonstrated negative remodeling of edge segments. PES was less effective than SES in inhibiting the growth of plaque within the first 1-mm length proximal to the stent.

Total TRIMPS correlated with square root of mean squared differences of successive RR intervals (r = –0.93; p<0.001), standard deviation of the RR intervals (r = –0.94; p<0.001), log normalised total power (r = –0.97; p<0.001), log normalised low frequency power (r = –0.79; p<0.02), and log normalised high frequency power (r = –0.94; p<0.001). Conclusion: HRV may be strongly affected by chronic exposure to heavy exertion. Training volume and intensity are necessary to delineate the degree of these alterations. PMID:15388541

    To determine whether postischemic diastolic stunning could be detected using color kinesis, we evaluated regional left ventricular (LV) diastolic wall motion in 36 patients with stable effort angina and a coronary stenosis (> or = 70% of luminal diameter), and in 30 control subjects. Regional LV filling fraction in the short-axis view during the first 30% of the LV filling time (color kinesis diastolic index) was determined before, 20 minutes, 1 hour, and 24 hours after the treadmill exercise test. In 33 of the 36 patients (92%), new regional LV delayed outward motion during early diastole (color kinesis diastolic index < or = 40%) was detected at 20 minutes after exercise. The regional LV delayed diastolic wall motion showed significant improvement but persisted 1 hour afterward in 20 of 36 patients (56%), and disappeared 24 hours after exercise. Detection of regional stunned myocardium with impaired diastolic function may be a useful tool for the diagnosis of coronary artery disease.

    Full Text Available Die intravenösen Glykoprotein IIb/IIIa-Antagonisten Abciximab, Tirofiban und Eptifibatide sind wissenschaftlich ohne Zweifel für die Therapie der instabilen Angina und als Begleitmedikation bei Koronarinterventionen etabliert, auch wenn die Anwendung dieser Substanzen in der klinischen Praxis noch ungenügend ist. Insbesondere für das Abciximab konnte eine Letalitätsreduktion auch 3 Jahre nach der Therapie für ein Hochrisikokollektiv von Patienten überzeugend nachgewiesen werden. Für die Therapie des akuten Myokardinfarktes zusammen mit verschiedenen Fibrinolytika werden alle drei Substanzen zur Zeit in größeren Studien untersucht. Die sehr umfangreichen Untersuchungen bei Patienten mit instabiler Angina und nach Koronarinterventionen, die mit den oralen Glykoprotein IIb/IIIa-Antagonisten durchgeführt wurden, haben allesamt enttäuschende Ergebnisse erbracht. Es konnten nur schwache therapeutische Effekte im Sinne einer Reduktion von ischämischen Rezidivereignissen festgestellt werden, wobei jedoch bei allen Untersuchungen eine Tendenz zu einer leicht erhöhten Letalität in der Therapiegruppe im Vergleich zur jeweiligen Placebogruppe festgestellt werden konnte. In einer Metaanalyse wurde eine ca. 35%ige Erhöhung der Sterblichkeit für die mit den oralen Antagonisten behandelten Patienten errechnet. Die Gründe für diesen therapeutischen Fehlschlag könnten in der geringen Bioverfügbarkeit der verschiedenen Substanzen liegen oder in dem bisher noch ungenügenden Verständnis des Verhaltens des thrombozytären GPIIb/IIIa-Rezeptors beim Versuch einer Langzeitblockade. Weitere Substanzen mit anderen pharmakokinetischen Eigenschaften sind derzeit noch in der klinischen Entwicklung.

    Full Text Available Abstract Background and purpose: Coronary Artery Disease (CAD is one of the most common causes of mortality and disability in the world. The results of some studies show that there are differences in signs and symptoms of CAD between male and female.Materials and Methods: This research was done to compare males and females for these signs and symptoms in 600 hospitalized patients in coronary care units of Kerman Medical University from December 2004 to July 2005. For data collection a questionnaire was used which was designed in five sections: demographic characteristics, disease variables, pictures for determining the points of chest pain, Visual Analog Scale for determining the intensity of pain and measures taken by patients after the beginning the signs and symptoms. This questionnaire was completed by two nurses in different shifts by interviewing the patients. For data analysis T test, χ2, Fisher exact and Man-Whitney U were used.Results: The results showed that the women were older than men (p<0.001. Most women had unstable angina and men had myocardial infarction (P<0.05. There were no significant differences between the chest pain in both genders but neck pain, back pain, fatigue, decrease of appetite, flushing, dizziness, tiredness, visual disturbances, suffocation feeling, palpitation and restlessness were experienced in women more than men (p<0.05. Also dyspenea during the heart attack was seen in most women (44.7% vs 29.4% but there was no significant difference between two genders for intensity of pain.Conclusion: This study showed that atypical signs and symptoms of unstable angina and myocardial infarction were seen in female more than male. Furthermore this may be followed by some problems in diagnosis and then delay in referring the patients to medical centers. On the other hand, health care workers may not pay enough attention to these atypical signs and symptoms, in women with normal ECG so they might not receive nessaceery

  2. Radiation pressure cross section exerted on homogenous dielectric spherical particle by zeroth order Mathieu beams

    Chafiq, A.; Belafhal, A.

    2016-08-01

    In this paper, we present a full calculation of radiation pressure cross section and optical forces exerted by linearly polarized zeroth order Mathieu beams on homogenous dielectric spherical particle in the framework of generalized Lorenz-Mie theory (GLMT). In this theory, the scattered fields are dependent upon the Mie scattering coefficients and the beam shape coefficients. So a new optical property such as force and torque appears by changing the beam profile and the nature of particle. In this way, this work is devoted to the analysis of both transverse and longitudinal optical forces exerted on a simple dielectric spherical particle by zeroth order Mathieu beams and zeroth order Bessel (which is a particular case of the first beam). Thus, through numerical simulations, we show that zeroth order Mathieu beams can't trap this particle but Bessel beam presents some dimensional stable equilibrium points.

    2015-01-01

    Full Text Available Inferior vena cava atresia (IVCA is a rare but well described vascular anomaly. It is a rare risk factor for deep venous thrombosis (DVT, found in approximately 5% of cases of unprovoked lower extremity (LE DVT in patients <30 years of age. Affected population is in the early thirties, predominantly male, often with a history of major physical exertion and presents with extensive or bilateral DVTs. Patients with IVC anomalies usually develop compensatory circulation through the collateral veins with enlarged azygous/hemizygous veins. Despite the compensatory circulation, the venous drainage of the lower limbs is often insufficient leading to venous stasis and thrombosis. We describe a case of extensive and bilateral deep venous thrombosis following physical exertion in a thirty-six-year-old male patient with incidental finding of IVCA on imaging.

    Background Proteases are well-known virulence factors that promote survival, pathogenesis and immune evasion of many pathogens. Several lines of evidence suggest that the blood–brain barrier permeability is a prerequisite in microbial invasion of the central nervous system. Because proteases are frequently associated with vascular permeability by targeting junctional proteins, here it is hypothesized that neuropathogenic Escherichia coli K1 exhibit proteolytic activities to exert its pathogen...

    2016-06-01

    Spinning is a popular indoor stationary cycling program that uses group classes as a motivational tool. Exertional rhabdomyolysis (ER) is frequently reported in athletes and military recruits; however, infrequently it has been reported after spinning class. ER is diagnosed by clinical history, physical exam, and laboratory values. Hydration, electrolyte management, and pain control are key components to treatment of this condition. Severe cases can be complicated by acute renal failure, compartment syndrome, arrhythmia, and disseminated intravascular coagulation. We describe three cases of admission due to rhabdomyolysis after spinning. The diagnosis, admission criteria, and medical treatment of ER are presented in the context of a literature review. A retrospective review of three cases with review of the current literature. The medical and laboratory records of three patient cases were reviewed. A search of the PubMed database was used to perform a comprehensive review of exertional rhabdomyolysis. Our institution's IRB reviewed this study. We report three cases of exertional rhabdomyolysis after spinning and describe the diagnostic workup and medical management of these patients. The diagnosis of ER is made by clinical history, physical exam, and laboratory values. The disease spectrum ranges from mild to severe with the potential of serious complications in some patients. We demonstrate three cases of ER in deconditioned individuals who presented to the emergency department for evaluation. Careful medical management and patient monitoring resulted in improved patient symptomatology and eventual return to physical activity.

  2. Activity limitation and exertional dyspnea in adult asthmatic patients: What do we know?

    2016-08-01

    Limitation of activity is the most cited symptom described by uncontrolled asthma patients. Assessment of activity limitation can be undertaken through several ways, more or less complex, subjective or objective. Yet little is known about the link between patients sensations and objective measurements. The present review reports the current knowledge regarding activity limitation and symptom perception (i.e., exertional dyspnea) in adult patients with asthma. This work is based on references indexed by PubMed, irrespective of the year of publication. Overall, patients with stable asthma do not have a more sedentary lifestyle than healthy subjects. However, during a cycle ergometric test, the maximal load is reduced when FEV1, FVC and muscle strengths are decreased. Additionally, during the six-minute walking test, mild asthma patients walk less than healthy subjects even if the minimal clinically important difference is not reached. The major complaint of asthma patients when exercising is dyspnea that is mainly related to the inspiratory effort and also to dynamic hyperinflation in some circumstances. Finally, the administration of bronchodilator does not improve the ventilatory pattern and the exercise capacity of asthma patients and little is known on its effect on exertional dyspnea. The present review allows to conclude that until now there is no gold standard test allowing the objective assessment of "activity limitation and exertional dyspnea" in asthma patients.

  3. Exertional Myopathy in a Juvenile Green Sea Turtle (Chelonia mydas Entangled in a Large Mesh Gillnet

    Full Text Available A juvenile female green sea turtle (Chelonia mydas was found entangled in a large mesh gillnet in Pamlico Sound, NC, and was weak upon presentation for treatment. Blood gas analysis revealed severe metabolic acidosis and hyperlactatemia. Plasma biochemistry analysis showed elevated aspartate aminotransferase and creatine kinase, marked hypercalcemia, hyperphosphatemia, and hyperkalemia. Death occurred within 24 hours of presentation despite treatment with intravenous and subcutaneous fluids and sodium bicarbonate. Necropsy revealed multifocal to diffuse pallor of the superficial and deep pectoral muscles. Mild, multifocal, and acute myofiber necrosis was identified by histopathological examination. While histological changes in the examined muscle were modest, the acid-base, mineral, and electrolyte abnormalities were sufficiently severe to contribute to this animal’s mortality. Exertional myopathy in reptiles has not been well characterized. Sea turtle mortality resulting from forced submergence has been attributed to blood gas derangements and seawater aspiration; however, exertional myopathy may also be an important contributing factor. If possible, sea turtles subjected to incidental capture and entanglement that exhibit weakness or dull mentation should be clinically evaluated prior to release to minimize the risk of delayed mortality. Treatment with appropriate fluid therapy and supportive care may mitigate the effects of exertional myopathy in some cases.

    Full Text Available Green exercise research often reports psychological health outcomes without rigorously controlling exercise. This study examines effects of visual exercise environments on directed attention, perceived exertion and time to exhaustion, whilst measuring and controlling the exercise component. Participants completed three experimental conditions in a randomized counterbalanced order. Conditions varied by video content viewed (nature; built; control during two consistently-ordered exercise bouts (Exercise 1: 60% VO2peakInt for 15-mins; Exercise 2: 85% VO2peakInt to voluntary exhaustion. In each condition, participants completed modified Backwards Digit Span tests (a measure of directed attention pre- and post-Exercise 1. Energy expenditure, respiratory exchange ratio and perceived exertion were measured during both exercise bouts. Time to exhaustion in Exercise 2 was also recorded. There was a significant time by condition interaction for Backwards Digit Span scores (F2,22 = 6.267, p = 0.007. Scores significantly improved in the nature condition (p < 0.001 but did not in the built or control conditions. There were no significant differences between conditions for either perceived exertion or physiological measures during either Exercise 1 or Exercise 2, or for time to exhaustion in Exercise 2. This was the first study to demonstrate effects of controlled exercise conducted in different visual environments on post-exercise directed attention. Via psychological mechanisms alone, visual nature facilitates attention restoration during moderate-intensity exercise.

    Full Text Available Background/Aim. Exertional heat stress is a common problem in military services. Considering the coagulation abnormalities are of major importance in development of severe heat stroke, we wanted to examine changes in hemostatic parameters in soldiers during exertional heat stress test as well as the effects of a 10-day passive or active acclimatization in a climatic chamber. Methods. A total of 40 male soldiers with high aerobic capacity performed exertional heat stress test (EHST either in cool [20ºC, 16ºC wet bulb globe temperature (WBGT], or hot (40ºC, 29ºC, (WBGT environment, unacclimatized (U or after 10 days of passive (P or active (A acclimatization. Physiological strain was measured by tympanic temperatures (Tty and heart rates (HR. Platelet count (PC, antithrombin III (AT, and prothrombin time (PT were assessed in blood samples collected before and immediately after the EHST. Results. EHST in hot conditions induced physiological heat stress (increase in Tty and HR, with a significant increase in prothrombin time in the groups U and A. Platelet counts were significantly higher after the EHST compared to the basic levels in all the investigated groups, regardless environmental conditions and acclimatization state. Antithrombin levels were not affected by EHST whatsoever. Conclusion. In the trained soldiers, physiological heat stress caused mild changes in some serum parameters of blood clotting such as prothrombin time, while others such as antithrombin levels were not affected. Platelet counts were increased after EHST in all groups. A 10-day passive or active acclimatization in climatic chamber showed no effect on parameters investigated.

    Cytoplasmic streaming is crucial for cell homeostasis and expansion but the precise driving forces are largely unknown. In plants, partial loss of cytoplasmic streaming due to chemical and genetic ablation of myosins supports the existence of yet-unknown motors for organelle movement. Here we tested a role of the endoplasmic reticulum (ER) as propelling force for cytoplasmic streaming during cell expansion. Through quantitative live-cell analyses in wild-type Arabidopsis thaliana cells and mutants with compromised ER structure and streaming, we demonstrate that cytoplasmic streaming undergoes profound changes during cell expansion and that it depends on motor forces co-exerted by the ER and the cytoskeleton.

    Patients with hepatic hemangiomas have been known to have high-output heart failure as a result of left-to-right arteriovenous shunting. We report a patient with a hepatic hemangioma that presented with high-output heart failure with hypoxia on exertion. After embolization of the hemangioma, the patient's hypoxia resolved and ejection fraction improved. In the absence of cardiopulmonary pathophysiology, we presume that our patient's hemangioma was causing a right-to-left shunt as opposed to an expected left-to-right shunt.

    We have developed a scheme to measure the optical torque, exerted by a laser beam on a phase object, by measuring the orbital angular momentum of the transmitted beam. The experiment is a macroscopic simulation of a situation in optical tweezers, as orbital angular momentum has been widely used to apply torque to microscopic objects. A hologram designed to generate LG02 modes and a CCD camera are used to detect the orbital component of the beam. Experimental results agree with theoretical numerical calculations, and the strength of the orbital component suggest its usefulness in optical tweezers for micromanipulation.

    Full Text Available Abstract Background Right sided arcus aorta (RSAA is a rare condition that is usually asymptomatic. Patients may present with exertional dyspnea and chronic cough. A recent article suggested that RSAA should be included in the differential diagnosis of asthma, especially in patients with intractable exertional dyspnea. We aimed to present the clinical, radiologic and spirometric features of thirteen patients with RSAA observed in four years at the Rize Education and Research Hospital and Samsun Chest Diseases and Thoracic Surgery Hospital. Methods The characteristics of patients with RSAA, including age, gender, symptoms, radiologic and spirometric findings, were retrospectively evaluated. Results A total of thirteen patients were diagnosed with RSAA. Their ages ranged from 17 to 86 years and the male to female ratio was 11:2. Seven of the patients (54% were symptomatic. The most common symptoms were exertional dyspnea, dysphagia and chronic cough. Five patients had received treatment for asthma with bronchodilators. Spirometry showed intrathoracic tracheal obstruction in five patients. Conclusions The RSAA anomaly occurs more frequently than might be estimated from the number of patients who are detected. Patients with intractable exertional dyspnea and chronic cough should be evaluated for the RSAA anomaly by thoracic CT.

    The efficacy of amlodipine, a long half-life dihydropyridine calcium antagonist, at the dosage of 5-10 mg/day in a single daily administration, has been compared with that of nifedipine R, a short half-life dihydropyridine, at the dosage of 20-40 mg b.i.d. in 29 patients with chronic ischemic heart disease. After a one week placebo period, patients were assigned to the treatment with amlodipine or nifedipine R, according to a randomized sequence and a cross-over, single-blind design, for two control periods of four weeks and without a wash-out interval between these two phases. During the stress test, a significant increase from baseline in test duration and in time to onset of ischemia and of angina have been obtained with both treatments; moreover amlodipine increased significantly the time to onset of ST segment deviation (-1 mm) and the time to maximum ST segment deviation compared with nifedipine R changes. Also with Holter monitoring and in the angina diary there was a significant reduction of anginal episodes. As regards safety profile, amlodipine treatment was associated with a significantly lower incidence of side effects compared with nifedipine R. This is probably due to the particular pharmacokinetics of amlodipine which, besides the long half-life which allows a single daily administration, shows a retarded peak (between the 6th and the 12th hour) with consequent reduction of phenomena connected with fast and excessive peripheral vasodilatation. In conclusion, amlodipine was as effective in reducing the signs of ischemia as nifedipine R, but compliance was better due to the single daily administration and so was tolerability. PMID:1388115

    1 Cinnarizine, an inhibitor of calcium ion transport across smooth muscle cell membrane, has been shown to exert an anti-asthmatic effect in patients with chronic asthma. 2 It is postulated that antagonism to calcium ion transport across the mast cell membrane may cause the compound to have a pharmacological effect similar to sodium cromoglycate. 3 Cinnarizine is orally active and its therapeutic effect is demonstrated in a double-blind, cross-over, placebo controlled study. 4 Patient benefit was shown by a significant improvement in peak flow rate. A non-significant trend towards a reduction in symptomatic bronchodilator usage and a decrease in asthma symptom score was also shown. 5 It is concluded that cinnarizine could well prove to be the first of a new family of anti-asthmatic drugs offering a protective effect when taken systemically.

    To investigate the effect of physical exertion on simple reaction time and continuous attention of sport participants, an experiment was conducted with 46 male university students and 12 male cyclists. The subjects were assigned to three experimental and two control groups. The subjects of the experimental groups were asked to perform, following a 5-min, period of warming up, a high intensity exercise protocol for 5 min., on a mechanically braked cycle ergometer (Group A) or a moderate intensity exercise protocol for 30 min, on the same cycle ergometer (Groups B and C). Shortly before and immediately after the physical exercise subjects of all groups were asked to perform a test of simple reaction time and continuous attention. The subjects of the control groups were asked to perform at rest both tests of the simple reaction time and the continuous attention twice, with a 10-min. and a 35-min. interval between the first and second attempts, respectively. The results did not support the notion that exercise of moderate or high intensity influences significantly the cognitive performance of aerobically trained or untrained subjects. The results are discussed in the light of the current research findings concerning exertion and human psychomotor performance. PMID:9638756

    Curcumin, a naturally occurring polyphenolic compound present in turmeric (Curcuma longa), exerts antitumor effects in various types of malignancy. However, the precise mechanisms responsible for the effects of curcumin on retinoblastoma (RB) cells have not been fully explored. In the present study, the molecular mechanisms by which curcumin exerts its anticancer effects in RB Y79 cells were investigated. The results showed that curcumin reduced cell viability in Y79 cells. Curcumin induced G1 phase arrest through downregulating the expression of cyclin D3 and cyclin-dependent kinase (CDK)2/6 and upregulating the expression of CDK inhibitor proteins p21 and p27. Curcumin-induced apoptosis of Y79 cells occurred through the activation of caspases-9/-3. Moreover, flow cytometric analysis showed that curcumin induced mitochondrial membrane potential (∆Ψm) collapse in Y79 cells. We also found that curcumin induced the phosphorylation of c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK). JNK and p38 MAPK inhibitors significantly suppressed curcumin‑induced activation of caspases-9/-3 and inhibited the apoptosis of Y79 cells. Taken together, our results suggest that curcumin induced the apoptosis of Y79 cells through the activation of JNK and p38 MAPK pathways. These findings provide a novel treatment strategy for human RB. PMID:27432244

    A naturally occurring bile acid, ursodeoxycholic acid (UDCA), is known to alleviate endoplasmic reticulum (ER) stress at the cellular level. However, the detailed action mechanisms of UDCA in atherosclerosis are not fully understood. In this study, we demonstrated whether UDCA exerts anti-atherogenic activity in diabetic atherosclerosis by targeting ER stress and "receptor for advanced glycation endproduct" (RAGE) signaling. UDCA markedly reduced ER stress, RAGE expression, and pro-inflammatory responses [including NF-κB activation and reactive oxygen species (ROS) production] induced in endothelial cells (ECs) by high glucose (HG). In particular, UDCA inhibited HG-induced ROS production by increasing the Nrf2 level. In macrophages, UDCA also blocked HG-induced RAGE and pro-inflammatory cytokine expression and inhibited foam cell formation via upregulation of the ATP-binding cassette (ABC) transporters, ABCA1 and ABCG1. In the diabetic mouse model, UDCA inhibited atheromatous plaque formation by decreasing ER stress, and the levels of RAGE and adhesion molecules. In conclusion, UDCA exerts an anti-atherogenic activity in diabetic atherosclerosis by targeting both ER stress and RAGE signaling. Our work implicates UDCA as a potential therapeutic agent for prevention or treatment of diabetic atherosclerosis. PMID:26807573

  5. Diorcinol D Exerts Fungicidal Action against Candida albicans through Cytoplasm Membrane Destruction and ROS Accumulation.

    Directory of Open Access Journals (Sweden)

    Ying Li

    Full Text Available Candida albicans, which is the most common human fungal pathogen, causes high mortality among immunocompromised patients. Antifungal drug resistance becomes a major challenge for the management of Candida infection. Diorcinol D (DD, a diphenyl ether derivative isolated from an endolichenic fungus, exerted fungicidal action against Candida species. In this study, we investigated the possible mechanism of its antifungal activity. The change of membrane dynamics and permeability suggested that the cell membrane was disrupted by the treatment of DD. This was further supported by the evidences of intracellular glycerol accumulation, alteration of cell ultrastructure, and down-regulation of genes involved in cell membrane synthesis. In addition, the treatment of C. albicans with DD resulted in the elevation of reactive oxygen species (ROS, which caused the dysfunction of mitochondria. These altogether suggested that DD exerted its antifungal activity through cytoplasmic membrane destruction and ROS accumulation. This finding is helpful to uncover the underlying mechanisms for the diphenyl ether derivatives and provides a potential application in fighting clinical fungal infections.

    The deposition of amyloid-β (Aβ) and neuroinflammation are critical pathological features of Alzheimer's disease (AD). Astrocytes are considered the principal immunoregulatory cells in the brain. Neurosteroid progesterone (PG) exerts neuromodulatory properties, particularly its potential therapeutic function in ameliorating AD. However, the role of PG and the neuroprotective mechanism involving in the regulation of neuroinflammation in astrocytes warrant further investigation. In this study, we found that Aβ significantly increased the processing of neuroinflammatory responses in astrocytes. The processing is induced by an increase activity of PERK/elF2ɑ-dependent endoplasmic reticulum (ER) stress. Additionally, the inhibition of ER stress activation by Salubrinal significantly suppressed the Aβ-induced neuroinflammatory responses in astrocytes. While the treatment of astrocytes with Aβ caused an increase of neuroinflammatory responses, PG significantly inhibited Aβ-induced neuroinflammatory cytokine production by suppressing ER stress activation together with attenuating PERK/elF2ɑ signalling. Taken together, these results indicate that PG exerts a neuroprotective effect against Aβ-induced neuroinflammatory responses, and significantly suppresses ER stress activation, which is an important mediator of the neurotoxic events occurring in Aβ-induced neuroinflammatory responses in astrocytes. These neuroprotective mechanisms may facilitate the development of therapies to ameliorate AD. PMID:26878478

Pretende o autor explicar seus casos de dor (um de causalgia no membro superior e três de angina de peito em portadores de esclerose coronária. Ora a anestesia terapêutica no gânglio estrelado, ora na cadeia ganglionar torácica simpática, ora a radioterapia, ora a psicoterapia removeram a dor "facilitada" a tal ponto que se tornara "dominante", isto é, mesmo estímulos inadequados a provocavam. Os doentes eram inválidos e recuperaram-se. A neurofisiologia moderna autoriza a interpretação dessa terapêutica: suprimiu-se - com a anestesia, com a radioterapia e com a psicoterapia - o circuito neural auto-alimentado reverberante, hiperfuncionante em todo ou em parte de seu trajeto, quer aferente ao córtex quer aferente às coronárias. O autor discute o valor clínico dos acessos anginosos apontando fatos que documentam que o acesso "ilegítimo" (psicógeno deve ter como causa a estimulação das aferências vegetativas ao córtex em qualquer ponto (ganglionar, medular ou cortical. Os acessos "legítimos", produzindo lesões transitórias ou definitivas e até morte,, devem ser explicados pela atividade das eferências vagais que executam os efetôres espásticos das coronárias.

    The objective of this study was to examine the effects of gender, exertion direction, angular velocity and wrist angle on simultaneous grip force and wrist torque under the isokinetic condition. The study used 20 participants (10 males and 10 females) and included 6 angular velocities (15, 30, 45, 60, 75, and 90 degrees /s) and 2 wrist exertion directions (flexion and extension) over the wrist range of motion of 70 degrees flexion to 60 degrees extension in 5 degrees increments. Similar to other studies, males and flexion exertion produced larger forces than females and extension exertion, respectively. However, the largest forces were generated at near extreme flexion of the wrist and the dependent variable of angular velocity was not practically significant. These results can contribute to the evaluation of cumulative trauma syndromes, but there is a need for more research on the dynamic measures of the hand and wrist complex and for standard development for dynamic force measurement.

    The electroencephalographic (EEG) activity patterns in humans during motor behaviour provide insight into normal motor control processes and for diagnostic and rehabilitation applications. While the patterns preceding brisk voluntary movements, and especially movement execution, are well described, there are few EEG studies that address the cortical activation patterns seen in isometric exertions and their planning. In this paper, we report on time and time-frequency EEG signatures in experiments in normal subjects (n=8), using multichannel EEG during motor preparation, planning and execution of directional centre-out arm isometric exertions performed at the wrist in the horizontal plane, in response to instruction-delay visual cues. Our observations suggest that isometric force exertions are accompanied by transient and sustained event-related potentials (ERP) and event-related (de-)synchronisations (ERD/ERS), comparable to those of a movement task. Furthermore, the ERPs and ERD/ERS are also observed during preparation and planning of the isometric task. Comparison of ear-lobe-referenced and surface Laplacian ERPs indicates the contribution of superficial sources in supplementary and pre-motor (FC(z)), parietal (CP(z)) and primary motor cortical areas (C₁ and FC₁) to ERPs (primarily negative peaks in frontal and positive peaks in parietal areas), but contribution of deep sources to sustained time-domain potentials (negativity in planning and positivity in execution). Transient and sustained ERD patterns in μ and β frequency bands of ear-lobe-referenced and surface Laplacian EEG indicate the contribution of both superficial and deep sources to ERD/ERS. As no physical displacement happens during the task, we can infer that the underlying mechanisms of motor-related ERPs and ERD/ERS patterns do not only depend on change in limb coordinate or muscle-length-dependent ascending sensory information and are primary generated by motor preparation, direction

    Full Text Available Background. High levels of Pentraxin 3 (PTX3 are reported in acute myocardial infarction (AMI. Aim. To investigate circulating levels and gene expression of PTX3 in patients with AMI and stable angina pectoris (AP undergoing PCI. Methods. Ten patients with AP and 20 patients with AMI were included. Blood samples were drawn before PCI in the AP group and after 3 and 12 hours and days 1, 3, 5, 7, and 14 in both groups. Results. Circulating PTX3 levels were higher in AMI compared to AP at 3 and 12 hours (P<0.001 and P=0.003. Within the AMI group, reduction from 3 hours to all later time points was observed (all P≤0.001. Within the AP group, increase from baseline to 3 hours (P=0.022, followed by reductions thereafter (all P<0.05, was observed. PTX3 mRNA increased in the AMI group from 3 hours to days 7 and 14 in a relative manner of 62% and 73%, while a relative reduction from baseline to 3 and 12 hours of 29% and 37% was seen in the AP group. Conclusion. High circulating PTX3 levels shortly after PCI in AMI indicate that AMI itself influences PTX3 levels. PTX3 mRNA might be in response to fluctuations in circulating levels.

    Full Text Available Aim. To analyze the cost structure for pharmacotherapy of patients with stable angina (SA, in particular, to compare the cost of pharmacotherapy with drugs, both included and not included into the official Standard of care (SC. Material and methods. Medical records of patients with SA (n=100 admitted to the cardiology department of Tver Regional Clinical Hospital in January-July 2010 were studied retrospectivelly. Costs of treatment with drugs specified in SC for patients with SA as well as drugs not included in SC were considered. Costs of pharmacotherapy and cost structure were determined. Pharmacoeconomical methods, especially ABC analysis, were partially used.  Results. Totally 65502.39 ruble was spent for pharmacotherapy of 100 patients with SA. Cost structure was the following: 32679.34 ruble was spent for drugs recommended by SC, 23698.18 ruble — for drugs not included in SC, and 9124.87 ruble — for drugs to treat concomitant diseases which are not taken into account by SC for patients with SA. Conclusion. SA pharmacotherapy counts 50% of the total cost for drugs recommended by SC, 36% — for drugs not included in SC but belonged to pharmacological class presented in SC, and 14% — drugs from pharmacological class not included in SC. In the process of new SC elaboration for SA patients it is necessary to take into account treatment costs of concomitant diseases especially diabetes mellitus which can account up to 9.5% of total treatment cost of SA patients.

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

    Through searching the clinical trial data of Yangxinshi Tablets, the total of 1281 cases were summed up for the effects of Yangxinshi Tablets on the treatment of angina pectoris, diabetes angina, stable angina, coronary heart disease. The clinical effects of Yangxinshi Tablets were as follows:the curative effect on angina was approximately 72.00%-95.30%, the curative effect on traditional Chinese medicine symptoms was 78.90%-95.00%, the curative effect on electrocardiogram was 42.90%-81.30%, and nitroglycerin stop reduction rate is generally determined to be valid for more than 50%. Compared with the chosen control drugs, clinical efficacy of Yangxinshi Tablets was better than isosorbide dinitrate and isosorbide mononitrate, which were western medicines. Clinical efficacy of the combination of isosorbide dinitrate and Yangxinshi Tablets was superior to Compound Danshen Tablets and Compound Danshen Granales, and equivalent to Musk Heart-saving Drop Pill. Combined application of Yangxinshi Tablets and hypoglycemic agents was effective in the treatment on diabetes angina. Consequently, Yangxinshi Tablets could reduce cardiac stress, increase coronary blood flow, resist myocardial ischemia, prolong antianoxia time, and lower blood pressure and blood lipids to a certain extent. Yangxinshi Tablets had good effects on coronary heart disease and angina, especially on Qi deficiency and blood stasis type angina and myocardial infarction. What is more, Yangxinshi Tablets could be used in a long time without toxic effect.%  检索养心氏片临床试验的文献,总结养心氏片治疗心绞痛、糖尿病性心绞痛、稳定型心绞痛、冠心病,共1281例。养心氏片临床疗效:心绞痛疗效总有效率72.0%~95.30%,中医症状疗效总有效率78.90%~95.00%,心电图疗效42.90%~81.30%;硝酸甘油停减率一般在50%以上判定为有效。与所选择的对照药相比,养心氏片的临床疗效优于所对照的西药硝酸异山梨酯(

    Full Text Available A 19-year-old male patient who wounded himself with a gun in the cranial region had a Glasgow coma scale of 3E. At posttraumatic day 7, locked-in syndrome was considered upon detection of vertical eye movements, meaningful winks, and quadriplegia. Apart from the classical view, computed tomography (CT and postmortem examination of the brain showed an infarct area in the cerebellum. However, vertebrobasilar artery system was normal. In this case report, we would like to present that unlike cases with ischemia, specific CT findings may not be evident in posttraumatic cases and ischemia may occur in the cerebellum as a result of the pressure exerted by a sound gun.
