  1. 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)

    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.

    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.

    2009-01-01

    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

    1986-09-01

    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.

    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.

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 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

    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.

    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.

    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.

    Cleophas, Ton J.M.; Niemeyer, Menco G.; van Der Wall, Ernst E.

    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

    Full Text Available Background: Enhanced external counterpulsation (EECP is a noninvasive technique used for patients with refractory angina pectoris. There are controversial data on the effectiveness of EECP in improving patients with refractory stable angina. The aim of the present study was to evaluate the effectiveness and safety of EECP for the treatment of patients with refractory angina pectoris.Methods: Twenty consecutive patients with refractory angina pectoris were treated with EECP, and their symptoms, echocardiographic measures, treadmill exercise test parameters, and Canadian Cardiovascular Society Class were evaluated before and immediately after EECP. The patients were followed up for 6months post treatment.Results: There were significant differences regarding total exercise time before and after treatment (p value < 0.001. The patients showed a significant reduction in angina classes III and IV immediately after EECP (p value < 0.001; for most of the patients, these beneficial effects were sustained for 6 months (p value = 0.010. There was no significant improvement in the echocardiographic parameters.Conclusion: EECP decreased symptoms and increased total exercise time in our study population. These beneficial effectswere sustained for 6 months.

    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.

    2015-01-01

    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

  14. 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

However, it has not yet been established whether SCS alters the quality of life (QoL) in these patients. Methods. 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

    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.

    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.

    The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. 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.

    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.

    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.

  15. 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

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.

    Full Text Available Die letzten Praxis-Empfehlungen der United States Agency for Health Care Policy and Research zum Thema "Diagnose und Behandlung der instabilen Angina Pectoris (IAP" stammen aus dem Jahre 1994 und wurden trotz der rasanten Fortschritte auf diesem Gebiet in den vergangenen 5 Jahren nicht erneuert. Das International Cardiology Forum (ICF hat Ende 1998 die existierenden Richtlinien diskutiert und Vorschläge gemacht, in welchen Bereichen die Diagnostik und die Therapie der IAP aufgrund der mittlerweile vorliegenden Daten modifiziert werden sollten. Es wurde übereinstimmend beschlossen, daß folgende Änderungen empfohlen werden: 1. Troponin T und Troponin I sollten die Palette der Myokardmarker im Serum für diagnostische und prognostische Zwecke erweitern; 2. niedermolekulere Heparine sollten Standard-Heparin als Antikoagulantium ersetzen; 3. neue thrombozyten-inhibierende Substanzen sollten zusätzlich zu Aspirin zur Anwendung kommen; 4. die Verwendung von cholesterinsenkenden Medikamenten in der Langzeitbehandlung dieser Patienten ist sinnvoll. In der vorliegenden Arbeit wurden die Hintergründe für die vorgerschlagenen Revisionen diskutiert, und es wird auf rezente wissenschaftliche Publikationen Bezug genommen.

    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)

    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.

    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

    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.

    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.

    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.

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.

    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.

    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

    Objective: To investigate the effects of Ginkgo leaf extract (GLE) on function of dendritic cells (DC) and Th1/Th2 cytokines in patients with unstable angina pectoris(UAP). Methods: Fifty-four patients with UAP were equally assigned into two groups, the treated group and the control group, both treated with conventional Western medicine, but with GLE given additionally to the treated group. Blood of all patients was taken before and 4 weeks after treatment to prepare the peripheral mononuclear cells, then which were incubated in the completed medium containing granulocyte-macrophage colony stimulatory factor (GMCSF) and interleukin-4 (IL-4) to induce mature DC. The expression of co-stimulating factor CD86 (B7-2) on the surface of DC was detected by flow cytometry, and the stimulating capacity of DC was determined by mixed lymphocyte reaction (MLR). The blood levels of cytokines, interferon-γ (IFN-γ), and IL-4, were analyzed by ELISA, and blood C-reactive protein (CRP) level by turbidimetry. Moreover, the direct effect of Ginkgolide B on CD86 expression on DC were also tested in vitro. Results: After treatment, CD86 expression on DC, the stimulating capacity of DC as well as levels of IFN-γ and CRP were lowered in both groups ( P<0.05 or P<0.01), but the changes were much more significant in the treated group than those in the control group. Ginkgolide B showed a direct inhibitory effect on the CD86 expression on DC. Conclusion: The inhibition of GLE on DC and thereby the suppression on inflammatory reaction may be one of the mechanisms of GLE in treating patients with UAP.

    2011-03-01

    Full Text Available Abstract Background Few studies investigated the association between smoking, alcohol consumption, or physical activity and the risk of unstable angina pectoris (UAP, while the strength of these associations may differ compared to other coronary diseases such as acute myocardial infarction (AMI. Therefore, we investigated whether the associations of these lifestyle factors with UAP differed from those with AMI. Additionally, we investigated whether these effects differed between subjects with and without a family history of myocardial infarction (MI. Methods The CAREMA study consists of 21,148 persons, aged 20-59 years at baseline and randomly sampled from the Maastricht region in 1987-1997. At baseline, all participants completed a self-administered questionnaire. After follow-up of maximally 16.9 years, 420 AMI and 274 UAP incident cases were registered. Incidence rate ratios (RRs were estimated using Cox proportional hazards models. Results For both diseases, smoking increased the risk while alcohol consumption was associated with a protective effect. Associations with both risk factors were stronger for AMI than UAP, although this difference was only statistically significant for smoking. In men, an inverse association was found with physical activity during leisure time which seemed to be stronger for the risk of UAP than of AMI. On the contrary, physical activity during leisure time was associated with an increased risk of both AMI and UAP in women which seemed to be weaker for UAP than for AMI. Except for occupational physical activity in women, no significant interactions on a multiplicative scale were found between the lifestyle factors and family history of MI. Nevertheless, the highest risks were found in subjects with both a positive family history and the most unfavorable level of the lifestyle factors. Conclusions The strength of the associations with the lifestyle factors did not differ between AMI and UAP, except for smoking

    Full Text Available Abstract Background Embolization of atherosclerotic debris from the rupture of a vulnerable atherosclerotic plaque occurs iatrogenically during percutaneous coronary interventions (PCI and can induce myocardial necrosis. These microembolizations are detected as high intensity transient signals (HITS using intracoronary Doppler technology. Presentation of the hypothesis In the presented study we will test if abciximab (ReoPro® infusion reduces high intensity transient signals in patients with stable angina pectoris undergoing PCI in comparison to standard therapy alone. Testing the hypothesis The High Intensity Transient Signals ReoPro® (HITS-RP study will enroll 60 patients. It is a prospective, single center, randomized, double-blinded, controlled trial. The study is designed to compare the efficacy of intravenous abciximab administration for reduction of microembolization during elective PCI. Patients will be randomized in a 1:1 fashion to abciximab or placebo infusion. The primary end point of the HITS-RP-Study is the number of HITS during PCI measured by intracoronary Doppler wire. Secondary endpoints are bleeding complications, elevation of cardiac biomarkers or ECG changes after percutaneous coronary interventions, changes in coronary flow velocity reserve, hs-CRP elevation, any major adverse cardio-vascular event during one month follow-up. Implications of the hypothesis The HITS-RP-Study addresses important questions regarding the efficacy of intravenous abciximab administration in reducing microembolization and periprocedural complications in stable angina pectoris patients undergoing PCI. Trial registration The trial is registered under http://www.drks-neu.uniklinik-freiburg.de/drks_web/:DRKS00000603.

  14. 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 We evaluated the effects of the Xuefu Zhuyu capsule (XFZY and the Shengmai capsule (SM on the evolution of syndromes and inflammatory markers in patients with unstable angina pectoris (UAP after percutaneous coronary intervention (PCI. Ninety patients with UAP after PCI were randomly and equally assigned to three groups: the XFZY group, the SM group, and the placebo group, with 30 patients in each group. Six syndrome factors (including Qi deficiency, yin deficiency, yang deficiency, blood stasis, phlegm, and Qi stagnation and 4 inflammatory markers (high-sensitivity C-reactive protein (Hs-CRP, endothelins-1 (ET-1, matrix metalloproteinases-9 (MMP-9, and homocysteine (Hcy were observed at week 0 and at the 1st, 4th and 12th weeks. In conclusion, the evolution of syndromes present in patients with UAP after PCI followed these trends (1 The deficiency syndromes gradually increased during a 12-week period, but the excess syndromes first gradually decreased and then mildly increased after PCI. (2 XFZY and SM can prevent excess syndromes from increasing in the later stages and prevent deficiency syndromes from increasing in all stages. (3 XFZY and SMcan reduce the levels of the inflammatory markers, especially in the later stages after PCI.

  17. Prinzmetal's variant angina evolved in inferior myocardial infarction with involvement of the right ventricle: Sequential radionuclide evaluation

    International Nuclear Information System (INIS)

    A patient with Prinzmetal's variant angina (PVA) who developed an inferolateral myocardial infarction with right-ventricle involvement was studied using sequential radionuclide imaging until 5 months after the acute event. The patient also underwent-contrast ventriculography and coronary-artery angiography. Equilibrium-gated radionuclide angiography (EGRA) revealed the localization of ventricular dysfunction, the results obtained being in agreement with haemodynamic data. We emphasize the usefulness of the parameters obtained using EGRA (regional wall motion, systolic and diastolic parameters) in planing therapy and follow-up. (orig.)

    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.

    Objective To evaluate the efficacy and safety of extracorporeal cardiac shock wave system ( CSWT ) in treating refractory angina pectoris patients. Methods Fifteen patients with severe coronary artery disease which was documented by coronary angiogram present with refractory angina pectoris were selected. The ischemic area was determined by the 99m Technetium-MIBI single-photon emission computed tomography (SPECT). The CSWT were performed in 3 months, and totally 9 times. The clinical evaluations include Canadian Cardiovascular Society ( CCS) class scores, New York Heart Association class ( NYHA ) , Seattle angina questionnaire ( SAQ ) , 6-min walking distance and the use of dosage of nitroglycerin;left ventricular end diastolic diameter ( LVEDD ) and left ventricular ejection of fraction ( LVEF) were also evaluated by echocardiography. The amelioration of ischemic myocardial was analyzed by SPECT, through comparison of myocardial perfusion scores and ischemic area before and after treatment. The variation of segment myocardial dysfunction was assessed by wall motion and wall thickening. Results CSWT obviously ameliorated CCS, NYHA, SAQ score, improved 6-min walking distance and decreased the use of nitroglycerin dose, but there was no significant changes in LVEDD and LVEF. SPECT date showed that in the treated segment, the rest myocardial perfusion score decreased from 1. 89 ± 0. 94 to 1. 37 ± 1. 07 (p=0. 004) and stress perfusion score also decreased from 2. 56 ±1. 19 to 1. 70 ±1. 27 (p=0. 000). The rest ischemic area decreased from 30. 81% ± 36. 60% to 17. 19% ± 28. 34% ( p =0. 004 ) and stress ischemic area from 61. 85% ± 30. 89% to 46. 31% ± 35. 72% ( p=0. 001 ) . The ventricular wall motion was improved from (6. 48 ± 2. 71) mm to (7. 49 ± 2. 43) mm (p=0. 007) and thickening from 44. 00% ± 22. 66% to 50. 46% ± 19. 91% (p=0. 038) in the rest, but no significant changes in the stress. There was no significant changes in CK, CKMB, TNT and there was no

    Full Text Available BACKGROUND: Virtual Histology Intravascular Ultrasound (VH-IVUS may be used to detect early signs of unstable coronary artery disease. Monocyte Chemoattractant Protein-1 (MCP-1 is linked with coronary atherosclerosis and plaque instability and could potentially be modified by folic acid treatment. METHODS: In a randomized, prospective study, 102 patients with stable angina pectoris (SAP received percutaneous coronary intervention and established medical treatment as well as either homocysteine-lowering folic acid/vitamin B12 (± B6 or placebo (± B6 for 1 year before VH-IVUS was performed. The presence of VH-Thin-Cap Fibroatheroma (VH-TCFA in non-intervened coronary vessels was registered and serum levels of MCP-1 were measured. The patients were subsequently followed for incident myocardial infarction (MI. RESULTS: Patients treated with folic acid/vitamin B12 had a geometric mean (SD MCP-1 level of 79.95 (1.49 versus 86.00 (1.43 pg/mL for patients receiving placebo (p-value 0.34. VH-TCFA lesions were present in 7.8% of patients and did not differ between intervention arms (p-value 0.47. Serum levels of MCP-1 were 1.46 (95% CI 1.12 to 1.92 times higher in patients with VH-TCFA lesions than in those without (p-value 0.005. Afterwards, patients were followed for median 2.1 years and 3.8% experienced a myocardial infarction (MI, which in post-hoc Cox regression analyses was independently predicted by both MCP-1 (P-value 0.006 and VH-TCFA (p-value 0.01. CONCLUSIONS: In patients with SAP receiving established medical treatment, folic acid supplementation is not associated with either presence of VH-TCFA or levels of MCP-1. MCP-1 is however associated with VH-TCFA, a finding corroborated by increased risk for future MI. ClinicalTrials.gov Identifier: NCT00354081.

    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 evaluate the therapeutic and adverse effect of small dose of aspirin (Asp) (UA). Methods: One hundred and twenty old in-patients of coronary heart disease with UA were randomly divided into two groups. The 60 patients in the treated group were treated with oral administration of enteric soluble 50 mg Asp once a day and GDI 20 ml per day by intravenous dripping, with 14 days as one therapeutic course, while the other 60 in the control group were treated with enteric soluble Asp 100 mg alone once a day orally. Besides, isosorbide-5-mononitrate 20 mg twice a day was applied to both groups, and the β-adrenoceptor blocker, blood lipids regulatory agents and nitroglycerin (10 mg by intravenous dripping) were given accordingly. The angina total improving rate, hemorrheologic indexes (whole blood viscosity, plasma viscosity, fibrinogen, platelet aggregation rate), comprehensive clinical terminal event and the total occurrence rate of adverse reaction in the two groups were observed. Results: After treatment, comparison between the two groups showed insignificant difference in aspects of angina total improving rate (75.00% vs 65.00 % ), hemorrheological indexes and comprehensive clinical terminal event rate (25.00 % vs 31. 67 % ),P>0.05, and the hemorrheological indexes were improved in both groups ( P<0.05), but the total occurrence rate of adverse reaction in the treated group was lower than that in the control group (6. 67% vs 25.00%), showing significant difference (P<0.05). Conclusion: In treatment of senile UA, small dose of Asp combined with GDI showed therapeutic effect similar to that of conventional dose of Asp, but it has lower adverse reaction.

    Objective To explore the effect and mechanism of Jiangzhi Tongluo Soft Gelatin Capsule (soft gelatin capsule for lowering lipid and freeing the network vessels) on angina pectoris. Methods Ninety-eight cases of angina pectoris were randomized into the observation group of 50 cases, and control group of 48 cases. Both groups were given the conventional therapy including antithrombotic therapy, stabling plague, calcium antagonists, β-receptor blocker, while Jiangzhi Tongluo Soft Gelatin Capsule and isosorbide mononitrate tablet was added in the observation group and the control group respectively through oral administration. The treatment course lasted for 12 weeks. The angina attack, chest tightness and the dosage of nitroglycerin were recorded daily. The levels of adiponectin (APN) and malondialdehyde (MDA) were detected before and after the treatment. Results Comparing in group, the angina attack and the dosage of nitroglycerin reduced significantly in both groups after the treatment (P0. 05). After treatment, the level of APN increased and the level of MDA decreased significantly in the observation group, while the increase of APN and the decrease of MDA in the control group was not significant (P>0. 05). The levels of triglycerides (TG), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were decreased significantly in the observation group after the treatment. There was significant difference in TG and high-density lipoprotein cholesterol (HDL-C) between groups after treatment (P<0. 01). The differences between groups in TG and high-density lipoprotein cholesterol (HDL-C) were statistically significant (P<0. 01). Conclusion Jiangzhi Tongluo Soft Gelatin Capsule is effective for angina as combined with the conventional therapy, which maybe relevant to inhibitting the inflammatory reaction and oxidative stress.%目的 探讨降脂通络软胶囊治疗冠心病心绞痛的疗效及作用机制.方法 将98例冠心病心绞痛患者经过2周

    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.

    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

    2016-09-01

    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.

    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

    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.

    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.

    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

    The informative value of programmed ventricular pacing (PVP), Holter monitoring (HM), and bicycle ergometry (BEM) in the diagnosis of myocardial electric instability was assessed in various clinical types of angina pectoris. An examination was made of 20 patients with first exercise-induced angina (FEIA), 33 with progressive exercise-induced angina (PEIA), 17 with spontaneous angina (SA), 30 with stable exercise-induced angina (SEIA), and postinfarction angina. Myocardial electric instability was estimated from HM and BEM findings in patients with FEIA, SA, as well as in PEIA, SEIA in the presence of preserved myocardial contractility as evidenced by ventriculography. A clear-cut correlation was found between transient myocardial ischemia and the occurrence of high-grade ventricular arrhythmias for the patients from the above-mentioned groups. Lower myocardial contractility despite the nature of angina is an indication for PVP.

    In recent years 99mTechnetium methoxy-isobutyl-isonitrile (99mTc MIBI) is widely used in the evaluation of myocardial perfusion imaging (MPI). In this imaging protocol besides the cardiac evaluation, numerous other organs are included in the field of view. 99mTechnetium MIBI is taken up in all metabolically active tissue in the body except for the brain. Extracardiac uptake patterns as benign or serious conditions can be revealed during the MPI. In the imaging protocol, we should be aware of distribution of this radiotracer in order to recognize the abnormal uptake. Here in, we present a large diaphragmatic hernia, seemed as a mirror vision of myocardium that was determined incidentally during the MPI with 99mTc MIBI. PMID:24379540

    We present a case of a 71-year-old male who hadchest symptoms at rest and during effort. He had felt chest oppression during effort for 1 year,and his chest symptoms had recently worsened. One month before admission he felt chest squeezing at rest in the early morning. He presented at our institution to evaluate his chest symptoms. Electrocardiography and echocardiography failed to show any specific changes. Because of the possibility that his chest symptoms were due to myocardial ischemia,he was admitted to our institution for coronary angiography(CAG). An initial CAG showed mild atherosclerotic changes in the proximal segment of the left anterior descending coronary artery(LAD) and mid-segment of the left circumflex coronary artery. Subsequent spasm provocation testing using acetylcholine revealed a bilateral coronary vasospasm,which was relieved after the intracoronary infusion of nitroglycerin. Finally,a CAG showed myocardial bridging(MB) of the mid-distal segments of the LAD. Fractional flow reserve using the intravenous administration of adenosine triphosphate was positive at 0.77,which jumped up to 0.90 through the myocardial bridging segments when the pressure wire was pulled back. Thus,coronary vasospasm and MB might have contributed to his chest symptoms at rest and during effort. Interventional cardiologists should consider the presence of MB as a potential cause of myocardial ischemia.

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.

    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.

    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.

    Full Text Available Introduction: Ischemic heart disease is caused mainly by obstruction of coronary arteries. The ischemic assessment through echocardiography is dependent on wall motion abnormality detection during systole. In patients with ischemic heart disease the diastolic function is impaired before systolic function and measurement of regional diastolic dysfunction if possible will be most sensitive for assessment of obstructed coronary artery region. This study was designed to determine whether regional left ventricular delayed relaxation diagnosis could be detected with strain imaging derived from two-dimensional speckle-tracking echocardiography in patients with coronary artery disease.Methods: All the articles reviewed were obtained using MEDLINE & ScienceDirect (up to October 2014. All data extracted by speckle tracking echocardiography. The index which is used is strain imaging diastolic index which is calculated as: (A-B A×100  . A is the amount of strain at the time Aortic value closure and B is the amount of strain in first one-third point of diastolic duration.Result: Four articles were reviewed. Three articles assessed patients with echocardiography at rest and one with stress echocardiography. All articles showed the coronary artery tracking with significant stenosis is possible by regional deformation analysis through two-dimensional strain.Discussion: The usage of strain images obtained through two-dimensional speckle tracking has been validated for the quantitation assessment of regional dysfunction in ischemic heart disease. Regional LV delayed relaxation diagnosis with strain imaging is a reliable method after treadmill stress test.Conclusion:  Strain imaging is reasonable for evaluation of ischemia as a low cost noninvasive test with high accuracy.

    baseline clinical characteristics who had undergone diagnostic coronary angiography for the first time were reviewed retrospectively. RESULTS: The frequency of significant CAD was significantly lower in COPD patients than in the control group (52.8% vs. 80.2%, p<0.001. Frequencies of CAD risk factors (older age, hypertension, diabetes, smoking history were significantly more frequent among COPD patients having significant CAD. Among patients reporting stable angina pectoris, significant CAD was detected in 32.7% of COPD patients and 71.0% of non-COPD patients (p<0.001. However, among the patients with a diagnosis of unstable angina pectoris, significant CAD was detected in 87.5% of COPD patients and 90.2% of non-COPD patients (p=0.755. CONCLUSION: Diagnosis of CAD in COPD patients by symptomatology may be difficult. However, clinical diagnosis of CAD in the setting of unstable angina is accurate in most of the COPD patients. Therefore, further noninvasive diagnostic methods or careful follow up may be more appropriate for COPD patients reporting stable angina pectoris.

    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)

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.

    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.

    Cervicothoracic Sympathectomy is a common indication in the treatment of Raynaud Syndrome, Palmer Hyperhidrosis or Acute Ischemia of the superior limb. Nonetheless, almost a century ago it represented one of the first innovative attempts in curing coronary heart disease. Nowadays, this indication is no more than a footnote in a volume on the History of Medicine, and a trivia fact for medical history enthusiasts. The operation's history is rather conflicting. A young Romaninan surgeon, Victor Gomoiu seems to have come up with the idea, in the early 20th century. However, his contribution remains unknown, after his successful collaboration with the famous surgeon and anatomist, Thoma Ionescu unfortunately turns into a dispute. This procedure was once thought cutting-edge. Furthermore it is the starting point for cardiovascular surgery. Whoever sparked the idea, gains an important place in the hall of fame of international surgery, that is why it is important to know its creator. PMID:27544937

    Isolated coronary artery ectasia (CAE) may be associated with stable or unstable coronary events despite the absence of epicardial coronary stenosis. Impaired coronary flow dynamics and myocardial perfusion have been demonstrated in stable patients with ectatic coronary arteries. We aimed to assess whether epicardial flow and tissue-level perfusion would be improved by diltiazem in myocardial regions subtended by the ectatic coronary arteries in patients with isolated CAE. A total of 60 patients with isolated CAE were identified of 9,780 patients who underwent elective coronary angiography. Patients were randomized to 5 mg of intracoronary diltiazem or saline. Coronary blood flow of the microvascular network was assessed using myocardial blush grade (MBG) technique. The thrombolysis in myocardial infarction (TIMI) flow grade and TIMI frame count (TFC) were used to assess epicardial coronary flow. MBG (from 2.4 to 2.6, p = 0.02), TIMI flow grades (from 2.4 to 2.8, p flow grade; and from 35 to 33, p = 0.43 for TFC). Diltiazem provided amelioration of the altered coronary flow dynamics, which was suggested as the pathophysiological influence of CAE. In conclusion, the favorable effects of the diltiazem on myocardial perfusion were observed at both epicardial and tissue levels.

  7. Assessment of myocardial fatty acid metabolism in patients with angina pectoris and diabetes mellitus using 123I-BMIPP myocardial scintigraphy

    International Nuclear Information System (INIS)

    We studied the effect of myocardial ischemia and diabetes mellitus (DM) on the myocardial fatty acid metabolism using 123I-BMIPP myocardial scintigraphy. We performed 123I-BMIPP myocardial scintigraphy in 50 patients with myocardial ischemia and without DM (AP), in 30 patients with myocardial ischemia and DM (AP+DM), 12 patients with DM and without myocardial ischemia (DM), and in 10 normal subjects (N). Myocardial uptake rate of 123I-BMIPP was obtained using the time activity curve. Myocardial washout rate of 123I-BMIPP was calculated using the polar images of early and delayed SPECT images. Myocardial uptake rate of 123I-BMIPP (%) were AP: 4.9±0.6, AP+DM: 5.5±0.5, DM 5.7±0.5 and N: 5.0±0.4. 123I-BMIPP myocardial uptake rate was increased in AP+DM and DM. 123I-BMIPP myocardial washout rate (%) were AP: 30.2±4.3, AP+DM: 24.5±3.9, DM: 16.1±2.8 and N: 19.4±3.2. 123I-BMIPP myocardial washout rate was increased in AP and AP+DM. 123I-BMIPP myocardial washout rate was increased particularly in patients with multi-vessels disease. 123I-BMIPP myocardial washout rate was decreased in DM. The present study suggested that diabetes mellitus increased myocardial fatty acid uptake and decreased myocardial fatty acid washout, and that myocardial ischemia increased myocardial fatty acid washout.

    A 64-year-old male patient had two episodes of transient ischemic attack and a cerebral infarction. Cerebral angiography showed 50% stenosis at the junction of left internal carotid artery and 90% stenosis at left mid-cerebral artery (MCA). Coronary angiography showed two vessel disease with arteriosclerotic change and underwent coronary artery bypass grafting. To prevent intraoperative cerebral infarction, we used brain protect solution just before starting ECC, set perfusion flow around 3 l/min/m2, monitored the flow of left MCA using Transcranial Doppler (TCD) and the saturation of left internal jugular vein (SjO2) continuously. PaCO2 was controlled around 45 mmHg. TCD showed good pulsatile flow, and SjO2 was kept over 60%. The patient recovered consciousness 2 hours after operation in the intensive care unit without paresthesia. We thought the number of open-heart cases with cerebrovascular disease increased, and pulsatile low of ECC by intraaortic balloon pumping and the monitoring of SjO2 are useful for the cases.

    ECG-exercise tests were performed in 29 patients affected by effort chest pain. All patients underwent coronary angiography and/or revealed positive results in the cycloergometer effort test. The aim of the study was to evaluate ultrasonic variations in the R and Q waves due to maximal effort, so as to increase the information provided by the effort ECG. In the coronary angiographic test, 21 out of 29 patients revealed significant hemodynamic coronary stenosis; 10 patients were affected by previous myocardial necrosis; 8 patients showed no hemodynamic coronary lesions (OV). In the OV patients a statistically significant increase was observed in the Q wave at maximal effort in comparison with average basal values; on the other hand, there was a decrease, although not significant, in voltage at peak effort in patients with coronary stenosis. R wave amplitude was smaller in comparison to basal values in OV patients, while a significant increase was observed in the 21 patients with coronary lesions. PMID:2622535

    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.

    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.

    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.

  13. 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

    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 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

    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.

    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)

    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.

    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.

    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

    Full Text Available Abstract Background Multi-detector computed tomography angiography (MDCTA has been increasingly used in the evaluation of the coronary arteries. The purpose of this study was to review the literature on the diagnostic performance of MDCTA in the acute setting, for the detection of non-ST-elevation myocardial infarction (NSTEMI and unstable angina pectoris (UAP. Methods A Pubmed and manual search of the literature published between January 2000 and June 2007 was performed. Studies were included that compared MDCTA with clinical outcome and/or CA in patients with acute chest pain, presenting at the emergency department. More specifically, studies that only included patients with initially negative cardiac enzymes suspected of having NSTEMI or UAP were included. Summary estimates of diagnostic odds ratio (DOR, sensitivity and specificity, negative (NLR and positive likelihood ratio (PLR were calculated on a patient basis. Random-effects models and summary receiver operating curve (SROC analysis were used to assess the diagnostic performance of MDCTA with 4 detectors or more. The proportion of non assessable scans (NAP on MDCTA was also evaluated. In addition, the influence of study characteristics of each study on diagnostic performance and NAP was investigated with multivariable logistic regression. Results Nine studies totalling 566 patients, were included in the meta-analysis: one randomised trial and eight prospective cohort studies. Five studies on 64-detector MDCTA and 4 studies on MDCTA with less than 64 detectors were included (32 detectors n = 1, 16 detectors n = 2, 16 and 4 detectors n = 1. Pooled DOR was 131.81 (95%CI, 50.90–341.31. The pooled sensitivity and specificity were 0.95 (95%CI, 0.90–0.98 and 0.90 (95%CI, 0.87–0.93. The pooled NLR and PLR were 0.12 (95%CI, 0.06–0.21 and 8,60 (95%CI, 5.03–14,69. The results of the logistic regressions showed that none of the investigated variables had influence on the diagnostic

    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

    Full Text Available Introduction: Coronary vasospasm is a possible cause of ventricular tachyarrhythmias and is frequently associated with atherosclerotic lesions. The revascularization of mild to moderate coronary artery stenosis which causes symptoms only due to associated vasospasm is still a matter of debate, as the standard treatment of Prinzmetal angina is represented by the long term administration of calcium-channel blockers.

    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.

    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) .

    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.

    Cyprus, located at the eastern end of the Mediterranean region, has been a place of eastern and western civilizations, and the presence of various hemoglobin (Hb) variants can be considered a testimony to past colonizations of the island. In this study, we report the structural Hb variants identified in the Cypriot population (Greek Cypriots, Maronites, Armenians, and Latinos) during the thalassemia screening of 248,000 subjects carried out at the Thalassaemia Centre, Nicosia, Cyprus, over a period of 26 years. A sample population of 65,668 people was used to determine the frequency and localization of several of the variants identified in Cyprus. The localization of some of the variants in regions where the presence of foreign people was most prevalent provides important clues to the origin of the variants. Twelve structural variants have been identified by DNA sequencing, nine concerning the beta-globin gene and three concerning the alpha-globin gene. The most common beta-globin variants identified were Hb S (0.2%), Hb D-Punjab (0.02%), and Hb Lepore-Washington-Boston (Hb Lepore-WB) (0.03%); the most common alpha-globin variant was Hb Setif (0.1%). The presence of some of these variants is likely to be directly linked to the history of Cyprus, as archeological monuments have been found throughout the island which signify the presence for many years of the Greeks, Syrians, Persians, Arabs, Byzantines, Franks, Venetians, and Turks.

    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.

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.

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.

    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.

    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 dif...

    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

    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 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.

    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.

Treatment is mainly based on corticosteroids and immunosuppressants. We report the case of a 33-year-old female complaining of malaise, fever, myalgia, severe pulsing holocranial headache resistant to analgesics, systemic arterial hypertension hard to control, right lower limb claudication, and severe abdominal pain that worsened after the meals. 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.

  1. Hemoglobin Variants in Mice

    1965-04-22

    Variability among mammalian hemoglobins was observed many years ago (35). The chemical basis for differences among hemoglobins from different species of mammals has been studied by several investigators (5, 11, 18, 48). As well as interspecies differences, hemoglobin variants are frequently found within a species of mammals (2, 3, 7, 16) The inheritance of these intraspecies variants can be studied, and pedigrees indicate that the type of hemoglobin synthesized in an individual is genetically controlled (20). Several of the variant human hemoglobins are f'unctionally deficient (7, 16). Such hemoglobin anomalies are of basic interest to man because of the vital role of hemoglobin for transporting oxygen to all tissues of the body.

    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

    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.

    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.

    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 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.

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.

    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.

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.).

    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

    Windmill nystagmus is characterized by a clock-like rotation of the beating direction of a jerk nystagmus suggesting separate horizontal and vertical oscillators, usually 90° out of phase. We report oculographic characteristics in three patients with variants of windmill nystagmus in whom the common denominator was profound visual loss due to retinal diseases. Two patients showed a clock-like pattern, while in the third, the nystagmus was largely diagonal (in phase or 180° out of phase) but also periodically changed direction by 180°. We hypothesize that windmill nystagmus is a unique manifestation of "eye movements of the blind." It emerges when the central structures, including the cerebellum, that normally keep eye movements calibrated and gaze steady can no longer perform their task, because they are deprived of the retinal image motion that signals a need for adaptive recalibration.

    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.

    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.

  15. The prevalence of angina symptoms and association with cardiovascular risk factors, among rural, urban and rural to urban migrant populations in Peru

    2010-10-01

    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. Results Compared to the urban group, rural dwellers had a greatly increased likelihood of possible/definite angina (multi-adjusted OR 2.82 (1.68- 4.73. Urban and migrant groups had higher levels of risk factors (e.g. smoking - 20.1% urban, 5.5% rural. No diabetes was seen in the rural dwellers who complained of possible/definite angina. Rural dwellers had a higher prevalence of mood disorder and the presence of a mood disorder was associated with possible/definite angina in all three groups, but not consistently with non-exertional chest pain. Conclusion Rural groups had a higher prevalence of angina as

    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

    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.

    Full Text Available Abstract Background Elevated white blood cell counts (WBC in acute coronary syndromes (ACS increase the risk of recurrent events, but it is not known if this is exacerbated by pro-inflammatory factors. We sought to identify whether pro-inflammatory genetic variants contributed to alterations in WBC and C-reactive protein (CRP in an ACS population. Methods WBC and genotype of interleukin 6 (IL-6 G-174C and of interleukin-1 receptor antagonist (IL1RN intronic repeat polymorphism were investigated in 732 Caucasian patients with ACS in the OPUS-TIMI-16 trial. Samples for measurement of WBC and inflammatory factors were taken at baseline, i.e. Within 72 hours of an acute myocardial infarction or an unstable angina event. Results An increased white blood cell count (WBC was associated with an increased C-reactive protein (r = 0.23, p 3 (95% CI = -0.41, 0.77, and -0.03/mm3 (95% CI = -0.55, 0.86 for IL1RN. Moreover, the composite endpoint was not significantly affected by an interaction between WBC and the IL1 (p = 0.61 or IL6 (p = 0.48 genotype. Conclusions Cytokine pro-inflammatory genetic variants do not influence the increased inflammatory profile of ACS patients.

  4. 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

    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

    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.

    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.

    Between 1981 and 1987 5434 patients were studied by ERCP in Allgemeines Krankenhaus Hamburg-Barmbeck. 26 (i.e. 0.43%) suffered from Mirizze syndrome with the triad of cholelithiasis, cholecystitis and obstructive biliary disease. They were classified in four different types according to the variable localisation and origin of the biliary obstruction. 16 patients corresponded to the classical type (I and II) with compression, penetration, and obturation by the concrement, five patients matched borderline with infiltration (III) and five patients were classified as variants of this syndrome. A mild elevation of serum bilirubine and alkaline phosphatase indicated more likely the benign etiology of type I to III, however, a marked elevation of alkaline phosphatase in the variants suggested more likely a malignant underlying disease. The diagnosis was ascertained in all cases by ERC and sonography preoperatively and was verified by laparotomy (n = 18) and follow-up (n = 6).

    Full Text Available Background. Microcystic variant of urothelial carcinoma is one of the new variants of urothelial carcinoma that was added to the WHO classification in 2004. Aims. To review the literature on microcystic variant of urothelial carcinoma. Methods. Various internet search engines were used to identify reported cases of the tumour. Results. Microscopic features of the tumour include: (i Conspicuous intracellular and intercellular lumina/microcysts encompassed by malignant urothelial or squamous cells. (ii The lumina are usually empty; may contain granular eosinophilic debris, mucin, or necrotic cells. (iii The cysts may be variable in size; round, or oval, up to 2 mm; lined by urothelium which are either flattened cells or low columnar cells however, they do not contain colonic epithelium or goblet cells; are infiltrative; invade the muscularis propria; mimic cystitis cystica and cystitis glandularis; occasionally exhibit neuroendocrine differentiation. (iv Elongated and irregular branching spaces are usually seen. About 17 cases of the tumour have been reported with only 2 patients who have survived. The tumour tends to be of high-grade and high-stage. There is no consensus opinion on the best option of treatment of the tumour. Conclusions. It would prove difficult at the moment to be dogmatic regarding its prognosis but it is a highly aggressive tumour. New cases of the tumour should be reported in order to document its biological behaviour.

    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 Coronary heart disease (CHD is a major cause of mortality. Morphological substrate of CHD in most cases is atherosclerosis, which is based on structural genes polymorphism eNOS and AGTR2. The aim of the study was to study the prevalence of eNOS and AGTR2 genes in patients with coronary artery disease and the association of these genes with coronary heart disease. The study involved 187 patients aged 36 to 86 years (62,2±11,2 with different forms of CHD: stable and unstable angina, myocardial infarction and 45 people without CHD. Determination of gene polymorphisms was performed by real-time PCR analyzer of nucleic acids IQ 5 Bio-Rad. Statistical analysis was performed using Statistica 10.0. The study revealed a significant difference between the incidence of homozygous AA allelic variant gene AGTR2 group of patients with myocardial infarction and the comparison group; polymorphic variant AA AGTR2 gene is associated with earlier onset of coronary artery disease; It found that carriers of the polymorphic variant gene GA AGTR2 beginning statistically CHD occurred significantly later than in carriers of alleles GG and AA; age CHD debut TT allele carriers of the eNOS gene is associated with an earlier onset of the disease and statistically significantly different from the age of first CHD in carriers of alleles of polymorphic variants of GG and GT; revealed a positive correlation between the polymorphic allele AGTR2 gene with the presence of arterial hypertension in patients with coronary artery disease; It determined that the T allele carriers of the polymorphic gene eNOS is associated more early onset of hypertension, found the association of the polymorphic allele gene AGTR2 the need to use higher doses of ACE inhibitor — perindopril.

    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.

    The demonstration of beneficial effects of salvia miltiorrhiza (DanShen) on ischemic diseases has revolutionized the management of angina pectoris, myocardial infarction (MI) or stroke in Chinese society. Experimental studies have shown that DanShen dilated coronary arteries, increased coronary blood flow, and scavenged free radicals in ischemic diseases, so that it reduced the cellular damage from ischemia and improved heart functions. Clinical trials also indicated that DanShen was an effective medicine for angina pectoris, MI, and stroke. This review will focus on DanShen's effects in angina pectoris, MI and stroke.

    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

    Nadja Knoll

    Full Text Available Heritability estimates for body mass index (BMI variation are high. For mothers and their offspring higher BMI correlations have been described than for fathers. Variation(s in the exclusively maternally inherited mitochondrial DNA (mtDNA might contribute to this parental effect. Thirty-two to 40 mtDNA single nucleotide polymorphisms (SNPs were available from genome-wide association study SNP arrays (Affymetrix 6.0. For discovery, we analyzed association in a case-control (CC sample of 1,158 extremely obese children and adolescents and 435 lean adult controls. For independent confirmation, 7,014 population-based adults were analyzed as CC sample of n = 1,697 obese cases (BMI ≥ 30 kg/m2 and n = 2,373 normal weight and lean controls (BMI<25 kg/m2. SNPs were analyzed as single SNPs and haplogroups determined by HaploGrep. Fisher's two-sided exact test was used for association testing. Moreover, the D-loop was re-sequenced (Sanger in 192 extremely obese children and adolescents and 192 lean adult controls. Association testing of detected variants was performed using Fisher's two-sided exact test. For discovery, nominal association with obesity was found for the frequent allele G of m.8994G/A (rs28358887, p = 0.002 located in ATP6. Haplogroup W was nominally overrepresented in the controls (p = 0.039. These findings could not be confirmed independently. For two of the 252 identified D-loop variants nominal association was detected (m.16292C/T, p = 0.007, m.16189T/C, p = 0.048. Only eight controls carried the m.16292T allele, five of whom belonged to haplogroup W that was initially enriched among these controls. m.16189T/C might create an uninterrupted poly-C tract located near a regulatory element involved in replication of mtDNA. Though follow-up of some D-loop variants still is conceivable, our hypothesis of a contribution of variation in the exclusively maternally inherited mtDNA to the observed larger correlations for BMI between mothers and

    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.

    2013-01-01

    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.

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.

    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.

    Full Text Available The paper proposes the fundamental portfolio of securities. This portfolio is an alternative for the classic Markowitz model, which combines fundamental analysis with portfolio analysis. The method’s main idea is based on the use of the TMAI1 synthetic measure and, in limiting conditions, the use of risk and the portfolio’s rate of return in the objective function. Different variants of fundamental portfolio have been considered under an empirical study. The effectiveness of the proposed solutions has been related to the classic portfolio constructed with the help of the Markowitz model and the WIG20 market index’s rate of return. All portfolios were constructed with data on rates of return for 2005. Their effectiveness in 2006- 2013 was then evaluated. The studied period comprises the end of the bull market, the 2007-2009 crisis, the 2010 bull market and the 2011 crisis. This allows for the evaluation of the solutions’ flexibility in various extreme situations. For the construction of the fundamental portfolio’s objective function and the TMAI, the study made use of financial and economic data on selected indicators retrieved from Notoria Serwis for 2005.

  15. Detecting Malware Variants by Byte Frequency

    Full Text Available In order to make lots of new malwares fast and cheaply, attacker can simply modify the existing malwares based on their binary files to produce new ones, malware variants. Malware variants refer to all the new malwares manually or automatically produced from any existing malware. However, such simple approach to produce malwares can change signatures of the original malware so that the new malware variants can confuse and bypass most of popular signature-based anti-malware tools. In this paper we propose a novel byte frequency based detecting model (BFBDM to deal with the malware variants identification issue. The byte frequency of software refers to the frequency of the different unsigned bytes in the corresponding binary file. In order to implement BFBDM, two metrics, the distance and the similarity between the suspicious software and base sample, a known malware, are defined and calculated. According to the experimental results, we found out that if the distance is low and the similarity is high, the suspicious software is a variant of the selected malware with very high probability. The primary experimental results show that our model is efficient and effective for the identification of malware variants, especially for the manual variant.

    In the last decades, understanding of genetic variants contributing to liver disease development has considerably improved through novel genotyping techniques. Genetic variants of single genes are known to be decisive for the development of monogenetic liver diseases of varying severity. Identification of genetic variants is an important part of the diagnostic process, e. g. the majority of patients with high iron [Fe] (HFE)-associated hemochromatosis carry the homozygous mutation p.C282Y. Detection of mutations in genes encoding hepatobiliary transport proteins like familial intrahepatic cholestasis 1 (FIC1), bile salt export pump (BSEP), or multidrug resistance protein 3 (MDR3) is the basis to differentiate various forms of intrahepatic cholestasis. Moreover, genetic variants in a variety of genes are known to act as disease modifiers and represent risk factors for disease progression and the development of cirrhosis or even hepatocellular carcinoma. Success of drug treatment or appearance of severe side effects can also be influenced by specific genetic variants. All these aspects underscore the increasing importance of genetic variants, which in the future may help to identify patients at risk for disease progression or help to guide treatment decisions. In the present overview, specific frequent genetic variants are summarized that play roles in monogenetic liver diseases, forms of intrahepatic cholestasis, gallstone development, fatty liver disease, drug-induced liver injury, and liver disease progression as well as hepatocellular carcinoma development.

    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.

    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.

    Conditionally replicating human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) variants that can be switched on and off at will are attractive tools for HIV and SIV research. We constructed HIV and SIV variants in which the natural transcription control mechanism was replaced by the doxycycline (dox)-inducible Tet-On gene expression mechanism. These HIV-rtTA and SIV-rtTA variants are fully replication-competent, but replication is critically dependent on dox administration. We here describe how the dox-dependent virus variants may improve the safety of live-attenuated virus vaccines and how they can be used to study the immune responses that correlate with vaccine-induced protection. Furthermore, we review how these variants were initially designed and subsequently optimized by spontaneous viral evolution. These efforts yielded efficiently replicating and tightly dox-controlled HIV-rtTA and SIV-rtTA variants that replicate in a variety of cell and tissue culture systems, and in human immune system (HIS) mice and macaques, respectively. These viruses can be used as a tool in HIV and SIV biology studies and in vaccine research. We review how HIV-rtTA and SIV-rtTA were used to study the role of the viral TAR and Tat elements in virus replication. PMID:25982510

    With the rise of sequencing technologies, it is now feasible to assess the role rare variants play in the genetic contribution to complex trait variation. While some of the earlier targeted sequencing studies successfully identified rare variants of large effect, unbiased gene discovery using exome sequencing has experienced limited success for complex traits. Nevertheless, rare variant association studies have demonstrated that rare variants do contribute to phenotypic variability, but sample sizes will likely have to be even larger than those of common variant association studies to be powered for the detection of genes and loci. Large-scale sequencing efforts of tens of thousands of individuals, such as the UK10K Project and aggregation efforts such as the Exome Aggregation Consortium, have made great strides in advancing our knowledge of the landscape of rare variation, but there remain many considerations when studying rare variation in the context of complex traits. We discuss these considerations in this review, presenting a broad range of topics at a high level as an introduction to rare variant analysis in complex traits including the issues of power, study design, sample ascertainment, de novo variation, and statistical testing approaches. Ultimately, as sequencing costs continue to decline, larger sequencing studies will yield clearer insights into the biological consequence of rare mutations and may reveal which genes play a role in the etiology of complex traits.

  8. Histone variants: key players of chromatin.

    2014-06-01

    Histones are fundamental structural components of chromatin. Eukaryotic DNA is wound around an octamer of the core histones H2A, H2B, H3, and H4. Binding of linker histone H1 promotes higher order chromatin organization. In addition to their structural role, histones impact chromatin function and dynamics by, e.g., post-translational histone modifications or the presence of specific histone variants. Histone variants exhibit differential expression timings (DNA replication-independent) and mRNA characteristics compared to canonical histones. Replacement of canonical histones with histone variants can affect nucleosome stability and help to create functionally distinct chromatin domains. In line with this, several histone variants have been implicated in the regulation of cellular processes such as DNA repair and transcriptional activity. In this review, we focus on recent progress in the study of core histone variants H2A.X, H2A.Z, macroH2A, H3.3, and CENP-A, as well as linker histone H1 variants, their functions and their links to development and disease.

    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

  10. 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 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

    2015-01-01

    This snapshot reviews the current state of knowledge on genetic variants of nuclear receptors (NRs) involved in regulating various aspects of liver metabolism. Interindividual differences in responses to diet and other 'in-' and environmental stressors can be caused by variants in components of the NR regulatory gene network. We recapitulate recent evidence for the application of NRs in genetic diagnosis of monogenic liver disease. Genetic analysis of multifactorial liver diseases, such as nonalcoholic fatty liver disease and diabetes mellitus, pinpoints key players in disease predisposition and progression. In particular, NR1H4 variants have been associated with intrahepatic cholestasis of pregnancy and gallstone disease. Other examples include studies of NR1I2 and NR1I3 polymorphisms in patients with drug-induced liver injury and NR5A2 variation in cholangiocarcinoma. Associations of NR gene variants have been identified in patients with dyslipidemia and other metabolic syndrome-associated traits by genome-wide studies. Evidence from these analyses confirms a role for NR variation in common diseases, linking regulatory networks to complex and variable phenotypes. These new insights into the impact of NR variants offer perspectives for their future use in diagnosis and treatment of common diseases. PMID:26045277

    Full Text Available Increasing numbers of historical texts are available in machine-readable form, which retain the original spelling, which can be very different from the modern-day equivalents due to the natural evolution of a language, and because the concept of standardisation in spelling is comparatively modern. Among medieval vernacular writers, the same word could be spelled in different ways and the same author (or scribe might even use several alternative spellings in the same passage. Thus, we do not know,a priori, how many variant forms of a particular word there are in such texts, let alone what these variants might be. Searching on the modern equivalent, or even the commonest historical variant, of a particular word may thus fail to retrieve an appreciable number of occurrences unless the searcher already has an extensive knowledge of the language of the documents. Moreover, even specialist scholars may be unaware of some idiosyncratic variants. Here, we consider the use of computer methods to retrieve variant historical spellings.

    Diseases affecting hemoglobin synthesis and function are extremely common worldwide. More than 1000 naturally occurring human hemoglobin variants with single amino acid substitutions throughout the molecule have been discovered, mainly through their clinical and/or laboratory manifestations. These variants alter hemoglobin structure and biochemical properties with physiological effects ranging from insignificant to severe. Studies of these mutations in patients and in the laboratory have produced a wealth of information on hemoglobin biochemistry and biology with significant implications for hematology practice. More generally, landmark studies of hemoglobin performed over the past 60 years have established important paradigms for the disciplines of structural biology, genetics, biochemistry, and medicine. Here we review the major classes of hemoglobin variants, emphasizing general concepts and illustrative examples.

    Full Text Available Abstract Many psychiatric conditions and traits are associated with significant heritability. Genetic risk for psychiatric conditions encompass rare variants, identified due to major effect, as well as common variants, the latter analyzed by association analyses. We review guidelines for common variant association analyses, undertaking after assessing evidence of heritability. We highlight the importance of: suitably large sample sizes; an experimental design that controls for ancestry; careful data cleaning; correction for multiple testing; small P values for positive findings; assessment of effect size for positive findings; and, inclusion of an independent replication sample. We also note the importance of a critical discussion of any prior findings, biological follow-up where possible, and a means of accessing the raw data.

    Melanoma is the most aggressive form of skin cancer with rising incidence and morbidity. Despite advances in treatment, the 10-yr survival for patients with metastatic disease is less than 10%. During the past few years, ongoing research on different epigenomic aberrations in melanoma has catalyzed better understanding of its pathogenesis and identification of new therapeutics. In our review, we will focus on the role of histone variants, key epigenetic players in melanoma initiation and progression. Specifically, incorporation of histone variants enables additional layers of chromatin structure, and here, we will describe how alterations in this epigenetic behavior impact melanoma.

    Full Text Available Parkinson's disease (PD, idiopathic and familial, is characterized by degradation of dopaminergic neurons and the presence of Lewy bodies (LB in the substantia nigra. LBs contain aggregated proteins of which α-synuclein is the major component. The protein synphilin-1 interacts and colocalizes with α-synuclein in LBs. The aim of this study was to isolate and characterize porcine synphilin-1 and isoforms hereof with the future perspective to use the pig as a model for Parkinson's disease. The porcine SNCAIP cDNA was cloned by reverse transcriptase PCR. The spatial expression of SNCAIP mRNA was investigated by RNAseq. The presented work reports the molecular cloning and characterization of the porcine (Sus scrofa synphilin-1 cDNA (SNCAIP and three splice variants hereof. The porcine SNCAIP cDNA codes for a protein (synphilin-1 of 919 amino acids which shows a high similarity to human (90% and to mouse (84% synphilin-1. Three shorter transcript variants of the synphilin-1 gene were identified, all lacking one or more exons. SNCAIP transcripts were detected in most examined organs and tissues and the highest expression was found in brain tissues and lung. Conserved splicing variants and a novel splice form of synhilin-1 were found in this study. All synphilin-1 isoforms encoded by the identified transcript variants lack functional domains important for protein degradation.

    Familial hypobetalipoproteinaemia is a rare autosomal dominant disorder in which levels of apo-B-containing plasma lipoproteins are approximately half-normal in heterozygotes and virtually absent in homozygotes. Here the authors describe mutations of the apo-B gene that cause two different truncated variants of apo-B in unrelated individuals with hypobetalipoproteinaemia. One variant is predicted to be 1,799 amino acids long and arises from deletion of a single nucleotide (G) from leucine codon 1,794. This protein was found at low levels in very low density and low density lipoprotein fractions in the blood. The second, shorter variant is caused by mutation of a CpG dinucleotide in arginine codon 1,306 converting it to a stop codon and predicting a protein of 1,305 residues. The differences in size and behavior of these two variants compared to apo-B100 or apo-B48 point to domains that may be important for the assembly, secretion or stability of apo-B-containing lipoproteins.

    Eukaryotic genomic DNA is highly packaged into chromatin by histones to fit inside the nucleus.Other than the bulk packaging role of canonical histones with an expression peak at S phase and replication-coupled deposition,different histone variants have evolved distinct regulatory mechanisms for their expression,deposition and functional implications.The diversity of histone variants results in structural plasticity of chromatin and highlights functionally distinct chromosomal domain,which plays critical roles in development from a fertilized egg into a complex organism,as well as in aging and diseases.However,the mechanisms of this fundamental process are poorly understood so far.It is of particular interest to investigate how the variants are incorporated into chromatin and mark specific chromatin states to regulate gene expression,and how they are involved in development and diseases.In this review,we focus on recent progress in studies of epigenetic regulation of three extensively investigated variants including H2A.Z,macroH2A and H3.3,and their functional implications in development and diseases.

    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.

    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 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

    The Saccharomyces Genome Database (SGD; http://www.yeastgenome.org) is the authoritative community resource for the Saccharomyces cerevisiae reference genome sequence and its annotation. In recent years, we have moved toward increased representation of sequence variation and allelic differences within S. cerevisiae. The publication of numerous additional genomes has motivated the creation of new tools for their annotation and analysis. Here we present the Variant Viewer: a dynamic open-source web application for the visualization of genomic and proteomic differences. Multiple sequence alignments have been constructed across high quality genome sequences from 11 different S. cerevisiae strains and stored in the SGD. The alignments and summaries are encoded in JSON and used to create a two-tiered dynamic view of the budding yeast pan-genome, available at http://www.yeastgenome.org/variant-viewer. PMID:26578556

    Full Text Available This review aims to provide a snapshot of the actual state of knowledge on genetic variants of nuclear receptors (NR involved in regulating important aspects of liver metabolism. It recapitulates recent evidence for the application of NR in genetic diagnosis of monogenic (“Mendelian” liver disease and their use in clinical diagnosis. Genetic analysis of multifactorial liver diseases such as viral hepatitis or fatty liver disease identifies key players in disease predisposition and progression. Evidence from these analyses points towards a role of NR polymorphisms in common diseases, linking regulatory networks to complex and variable phenotypes. The new insights into NR variants also offer perspectives and cautionary advice for their use as handles towards diagnosis and treatment.

    Existing methods for identifying structural variants (SVs) from short read datasets are inaccurate. This complicates disease-gene identification and efforts to understand the consequences of genetic variation. In response, we have created Wham (Whole-genome Alignment Metrics) to provide a single, integrated framework for both structural variant calling and association testing, thereby bypassing many of the difficulties that currently frustrate attempts to employ SVs in association testing. Here we describe Wham, benchmark it against three other widely used SV identification tools-Lumpy, Delly and SoftSearch-and demonstrate Wham's ability to identify and associate SVs with phenotypes using data from humans, domestic pigeons, and vaccinia virus.

    The Hill cipher is a classical symmetric encryption algorithm that succumbs to the know-plaintext attack. Although its vulnerability to cryptanalysis has rendered it unusable in practice, it still serves an important pedagogical role in cryptology and linear algebra. In this paper, a variant of the Hill cipher is introduced that makes the Hill cipher secure while it retains the efficiency. The proposed scheme includes a ciphering core for which a cryptographic protocol is introduced.

    Odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. Ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. We previously described orosomucoid-1 protein expression in odontogenic myxomas. However, whether orosomucoid-1 is expressed in other odontogenic tumors remains unknown. Since orosomucoid-1 belongs to a group of acute-phase proteins and has many functions in health and disease, we identified and analyzed orosomucoid-1 expression in ameloblastoma variants and ameloblastic carcinoma using western blot and immunohistochemical techniques. Thirty cases of ameloblastoma were analyzed for orsomucoid-1; five specimens were fresh for western blot study (four benign ameloblastomas and one ameloblastic carcinoma), and 25 cases of benign ameloblastoma for immunohistochemical assays. Orosomucoid-1 was widely expressed in each tumor variant analyzed in this study, and differential orosomucoid-1 expression was observed between benign and malignant tumor. Orosomucoid-1 may play an important role in the behavior of ameloblastomas and influence the biology and development of the variants of this tumor. PMID:27386438

    Diabetic nephropathy accounts for the most serious microvascular complication of diabetes mellitus. It is suggested that the prevalence of diabetic nephropathy will continue to increase in future posing a major challenge to the healthcare system resulting in increased morbidity and mortality. It occurs as a result of interaction between both genetic and environmental factors in individuals with both type 1 and type 2 diabetes. Genetic susceptibility has been proposed as an important factor for the development and progression of diabetic nephropathy, and various research efforts are being executed worldwide to identify the susceptibility gene for diabetic nephropathy. Numerous single nucleotide polymorphisms have been found in various genes giving rise to various gene variants which have been found to play a major role in genetic susceptibility to diabetic nephropathy. The risk of developing diabetic nephropathy is increased several times by inheriting risk alleles at susceptibility loci of various genes like ACE, IL, TNF-α, COL4A1, e NOS, SOD2, APOE, GLUT, etc. The identification of these genetic variants at a biomarker level could thus, allow the detection of those individuals at high risk for diabetic nephropathy which could thus help in the treatment, diagnosis and early prevention of the disease. The present review discusses about the various gene variants found till date to be associated with diabetic nephropathy.

    2015-01-01

    Context: Primary aldosteronism is one of the leading causes of secondary hypertension, causing significant morbidity and mortality. A number of genetic defects have recently been identified in primary aldosteronism, whereas we identified mutations in ARMC5, a tumor-suppressor gene, in cortisol-producing primary macronodular adrenal hyperplasia. Objective: We investigated a cohort of 56 patients who were referred to the National Institutes of Health for evaluation of primary aldosteronism for ARMC5 defects. Methods: Patients underwent step-wise diagnosis, with measurement of serum aldosterone and plasma renin activity followed by imaging, saline suppression and/or oral salt loading tests, plus adrenal venous sampling. Cortisol secretion was also evaluated; unilateral or bilateral adrenalectomy was performed, if indicated. DNA, protein, and transfection studies in H295R cells were conducted by standard methods. Results: We identified 12 germline ARMC5 genetic alterations in 20 unrelated and two related individuals in our cohort (39.3%). ARMC5 sequence changes in 6 patients (10.7%) were predicted to be damaging by in silico analysis. All affected patients carrying a variant predicted to be damaging were African Americans (P = .0023). Conclusions: Germline ARMC5 variants may be associated with primary aldosteronism. Additional cohorts of patients with primary aldosteronism and metabolic syndrome, particularly African Americans, should be screened for ARMC5 sequence variants because these may underlie part of the known increased predisposition of African Americans to low renin hypertension.

    needed to classify whether these uncertain variants are pathogenic or benign. In this study, we investigated 14 BRCA1 variants by in silico splicing analysis and mini-gene splicing assay. All 14 alterations were missense variants located within the BRCT domain of BRCA1 and had previously been examined...... by functional analysis at the protein level. Results from a validated mini-gene splicing assay indicated that nine BRCA1 variants resulted in splicing aberrations leading to truncated transcripts and thus can be considered pathogenic (c.4987A>T/p.Met1663Leu, c.4988T>A/p.Met1663Lys, c.5072C>T/p.Thr1691Ile, c...... to have no or an uncertain effect on the protein level, whereas one variant (c.5072C>T/p.Thr1691Ile) were shown to have a strong effect on the protein level as well.

    A new selection criterion to explain the activation of the twinning variant is proposed. This criterion is based on the calculation of the deformation energy to create a primary twin. The calculation takes into account the effect of the grain size using a Hall-Petch type relation. This criterion allows to obtain a very good prediction for the twin family selection and twin variant selection. The calculations are compared with the experimental results obtained on T40 (ASTM grade 2) deformed by Channel Die compression. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co.

  20. Joint Analysis of Multiple Traits in Rare Variant Association Studies.

    2016-05-01

    The joint analysis of multiple traits has recently become popular since it can increase statistical power to detect genetic variants and there is increasing evidence showing that pleiotropy is a widespread phenomenon in complex diseases. Currently, the majority of existing methods for the joint analysis of multiple traits test association between one common variant and multiple traits. However, the variant-by-variant methods for common variant association studies may not be optimal for rare variant association studies due to the allelic heterogeneity as well as the extreme rarity of individual variants. Current statistical methods for rare variant association studies are for one single trait only. In this paper, we propose an adaptive weighting reverse regression (AWRR) method to test association between multiple traits and rare variants in a genomic region. AWRR is robust to the directions of effects of causal variants and is also robust to the directions of association of traits. Using extensive simulation studies, we compare the performance of AWRR with canonical correlation analysis (CCA), Single-TOW, and the weighted sum reverse regression (WSRR). Our results show that, in all of the simulation scenarios, AWRR is consistently more powerful than CCA. In most scenarios, AWRR is more powerful than Single-TOW and WSRR. PMID:26990300

    This paper describes the advantage of the trapezoidal filter used in semiconductor detector system comparing with the other time variant filters. The trapezoidal filter is the compose of a rectangular pre-filter and a gated integrator. We indicate that the best performance is obtained by the differential-integral summing type rectangular pre-filter. This filter is not only superior in performance, but also has the useful feature that the rising edge of the output waveform is linear. We introduce an example of this feature used in a high-energy experiment. (author)

    Most pitfalls in the interpretation of pediatric chest imaging are closely related with the technique used and the characteristics of pediatric patients. To obtain a quality image that will enable the correct diagnosis, it is very important to use an appropriate technique. It is important to know how technical factors influence the image and to be aware of the possible artifacts that can result from poor patient cooperation. Moreover, radiologists need to be familiar with the normal anatomy in children, with the classic radiologic findings, and with the anatomic and developmental variants to avoid misinterpreting normal findings as pathological.

    Full Text Available Knowledge of variation of position of the medial plantar nerve is important for the forefoot surgeon for plantar reconstruction, local injection therapy and an excision of interdigital neuroma. During routine dissection of 50-year-old female cadaver, we found the medial plantar nerve and vessels variably located between plantar aponeurosis and the muscles of the first layer of the sole of the right foot. Due to this variant position, the medial plantar nerve and vessels lose their protection from the muscles of the first layer of the sole of the foot and became vulnerable for compression.

    We experimentally generate an Airy beam with polarization structure while keeping its original amplitude and phase profile intact. This class of Airy beam preserves the acceleration properties. By monitoring their initial polarization structure we have provided insight concerning the self-healing mechanism of Airy beams. We investigate both theoretically and experimentally the self-healing polarization properties of the space-variant polarized Airy beams. Amplitude as well as the polarization structure tends to reform during propagation in spite of the severe truncation of the beam by finite apertures.

    2015-01-01

    The hepatitis B virus (HBV) is a global public health problem with more than 240 million people chronicallyinfected worldwide, who are at risk for end-stage liverdisease and hepatocellular carcinoma. There are anestimated 600000 deaths annually from complications ofHBV-related liver disease. Antiviral therapy with nucleos/tide analogs (NA) targeting the HBV polymerase (P) caninhibit disease progression by long-term suppression ofHBV replication. However, treatment may fail with firstgeneration NA therapy due to the emergence of drugresistantmutants, as well as incomplete medicationadherence. The HBV replicates via an error-prone reversetranscriptase leading to quasispecies. Due to overlappingopen reading frames mutations within the HBV P cancause concomitant changes in the HBV surface gene (S )and vice versa. HBV quasispecies diversity is associatedwith response to antiviral therapy, disease severity andlong-term clinical outcomes. Specific mutants havebeen associated with antiviral drug resistance, immuneescape, liver fibrosis development and tumorgenesis.An understanding of HBV variants and their clinicalrelevance may be important for monitoring chronichepatitis B disease progression and treatment response.In this review, we will discuss HBV molecular virology,mechanism of variant development, and their potentialclinical impact.

    Full Text Available O autor traz à consideração clínica a "facilitação" que Sherrington apreciou nos experimentos de neurofisiologia, e que explica aspectos clínicos importantíssimos em psicologia e em neurologia visceral. 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. A dor é apresentada como fenômeno de "gravação neural", aprendido, memorizado e automatizado, ativado em feed-back ora nas aferências vegetativas ao córtex, ora nas eferências, mais perigosas e mortais. Debate-se a superestimada psicogenia da angina de peito.

    New technologies have recently enabled saturation mutagenesis and functional analysis of nearly all possible variants of regulatory elements or proteins of interest in single experiments. Here we discuss the past, present, and future of such multiplexed (functional) assays for variant effects (MAVEs). MAVEs provide detailed insight into sequence-function relationships, and they may prove critical for the prospective clinical interpretation of genetic variants. PMID:27583640

  15. Population structure analysis using rare and common functional variants

    Full Text Available Abstract Next-generation sequencing technologies now make it possible to genotype and measure hundreds of thousands of rare genetic variations in individuals across the genome. Characterization of high-density genetic variation facilitates control of population genetic structure on a finer scale before large-scale genotyping in disease genetics studies. Population structure is a well-known, prevalent, and important factor in common variant genetic studies, but its relevance in rare variants is unclear. We perform an extensive population structure analysis using common and rare functional variants from the Genetic Analysis Workshop 17 mini-exome sequence. The analysis based on common functional variants required 388 principal components to account for 90% of the variation in population structure. However, an analysis based on rare variants required 532 significant principal components to account for similar levels of variation. Using rare variants, we detected fine-scale substructure beyond the population structure identified using common functional variants. Our results show that the level of population structure embedded in rare variant data is different from the level embedded in common variant data and that correcting for population structure is only as good as the level one wishes to correct.

  16. A unified phylogeny-based nomenclature for histone variants

    Full Text Available Abstract Histone variants are non-allelic protein isoforms that play key roles in diversifying chromatin structure. The known number of such variants has greatly increased in recent years, but the lack of naming conventions for them has led to a variety of naming styles, multiple synonyms and misleading homographs that obscure variant relationships and complicate database searches. We propose here a unified nomenclature for variants of all five classes of histones that uses consistent but flexible naming conventions to produce names that are informative and readily searchable. The nomenclature builds on historical usage and incorporates phylogenetic relationships, which are strong predictors of structure and function. A key feature is the consistent use of punctuation to represent phylogenetic divergence, making explicit the relationships among variant subtypes that have previously been implicit or unclear. We recommend that by default new histone variants be named with organism-specific paralog-number suffixes that lack phylogenetic implication, while letter suffixes be reserved for structurally distinct clades of variants. For clarity and searchability, we encourage the use of descriptors that are separate from the phylogeny-based variant name to indicate developmental and other properties of variants that may be independent of structure.

    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.

    Although next-generation sequencing technology allows sequencing the whole genome of large groups of individuals, the development of powerful statistical methods for rare variant association studies is still underway. Even though many statistical methods have been developed for mapping rare variants, most of these methods are for unrelated individuals only, whereas family data have been shown to improve power to detect rare variants. The majority of the existing methods for unrelated individu...

    Increasing evidence shows that complex diseases are caused by both common and rare variants. Recently, several statistical methods for detecting associations of rare variants have been developed, including the test for testing the effect of an optimally weighted combination of variants (TOW) developed by our group in 2012. These methodologies consider phenotype measurement at only one time point. Because many sequence data have been developed on population cohorts that contain phenotype measu...
