    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.

    Therapeutic decisions in patients with angina pectoris are traditionally based on the history reported by the patient, since objective evidence of myocardial ischaemia during daily life is often not available. In this study, ambulatory ST segment monitoring was performed in 60 patients...... with a history of chronic stable angina pectoris, positive exercise test and/or positive coronary angiography, and a correlation was made between the episodes of chest pain and ST segment change. The patients were grouped according to the results of exercise testing and coronary arteriography, and one group...... was studied with and without antianginal medication. Overall, 195 episodes of angina were noted, only 94 of which (48%) were accompanied by ST segment depression. Pain and ST segment changes were best correlated in patients with a positive exercise test, positive angiography and who were not receiving...

    Full Text Available Background. Terminalia arjuna is a popular Indian medicinal plant with its bark been used for over centuries as cardiotonic. The bark has been found to contain several bioactive compounds including saponins and flavonoids. A number of experimental and clinical studies have been conducted to explore therapeutic potential of Terminalia arjuna in cardiovascular ailments specially in patients of coronary heart disease. A number of narrative reviews have been done but no systematic review has been conducted to date. Objective. To systematically review and conduct a meta-analysis on the available literature evaluating the efficacy of Terminalia arjuna in patients of chronic stable angina. Study selection. We included randomised, pseudo-randomized and before-after comparative studies which compared Terminalia arjuna/commercial preparation of Terminalia arjuna with current standard/ conventional treatment regimens in patients with chronic stable angina. Findings. Studies were found to be of poor methodological design. We found no significant difference in the Terminalia arjuna group as compared to control arm in the outcomes for which we were able to pool data and undertake meta-analysis. Conclusions. Currently, the evidence is insufficient to draw any definite conclusions in favour of or against Terminalia arjuna in patients of chronic stable angina. Further, well-controlled multicentric clinical trials need to be conducted in large number of patients to explore the therapeutic potential of Terminalia arjuna if any.

Angina results from an imbalance between myocardial oxygen supply and demand. Heart rate (HR reduction can beneficially alter both elements of this imbalance by increasing diastolic filling time and reducing myocardial oxygen demand. Therefore, HR reduction is an accepted approach to angina prevention. ß-blockers, calcium-channel blockers, and long-acting nitrates are currently the cornerstones in prevention and management of stable angina. However, use of these treatments may be limited by adverse effects or development of tolerance. Thus, additional approaches to angina prevention may be useful for many patients with CAD. The discovery of the f-channel and the resulting current, If, that modulates the rate of spontaneous diastolic depolarization of sinoatrial nodal (SAN myocytes led to the study of these channels as targets for lowering HR. This resulted in the development of a novel agent, ivabradine, a selective and specific If inhibitor. Ivabradine slows the slope of diastolic depolarization of the action potential in the SAN cells, decreasing HR at rest and during exercise, but has no other cardiovascular effects. In different subpopulations with chronic stable angina, ivabradine markedly improves exercise capacity and significantly decreases the number of ambient angina attacks. In a post-hoc analysis of the BEAUTIFUL trial (morBidity-mortality EvAlUaTion of the If inhibitor ivabradine in patients with coronary disease and left-ventricULar dysfunction, ivabradine also reduced mortality, myocardial infarctions, and heart failure hospitalizations among patients with angina.

In the cross-sectional study included 122 patients with CHD associated with COPD: 68 people of them are patients with stable angina without acute coronary events in history and 54 patients with acute ST segment elevation myocardial infarction (STEMI. Comparison group comprised 53 patients with stable angina and 51 patients after STEMI without concomitant COPD. Patients were included if they met the following inclusion criteria: male, age <60 years, verified forms of CHD (stable angina, STEMI, documented with COPD without exacerbation and forced expiratory volume in 1 second > 30% in the groups with CHD and COPD. Arterial endothelial function was tested with high-resolution ultrasonography: brachial artery diameter was measured at rest, after flow increase (which causes endothelium-dependent dilatation, and after administration of sublingual nitroglycerin (an endothelium-independent dilator.Results. We found that endothelial dysfunction in patients with acute and chronic forms of CHD in combination with COPD are more pronounced than in isolated CHD.Conclusion. Expressed depression functional vascular reserve in patients with CHD associated with COPD, should be taken into account when conducting individualized therapy of these patients.

    This is the first reported large clinical trial of the antianginal and acute ischemic effectiveness and safety of dilevalol (the R, R-isomer of labetalol) in patients with chronic stable angina pectoris. This was a multicenter double blind fixed-dose parallel group placebo controlled trial. Patients with chronic stable angina and positive and reproducible exercise tests (+/- 20%) were included. If randomized, patients entered one of four fixed dose groups (twice a day placebo, 100 mgm, 200 mgm and 400 mgm bid for 2 weeks). Exercise testing was performed at 2 hours (peak) and 12 hours (trough) postdosing. This was followed by a 2-week once-a-day dosing regimen in which patients received the same total daily dose as the prior 2 weeks, with the full dose in the morning and a matched placebo in the evening. Exercise testing was performed at 2 hours (peak) and 24 hours (trough) postdosing. Anginal frequency and NTG consumption were significantly reduced, and equally so, by qd and bid regimens. The time of exercise to the onset of angina increased and the proportion of patients terminating exercise because of moderate angina decreased in a dose response fashion for both peak and trough tests and for both qd and bid regimens. There was also a dose related decrease in exercise induced ST segment depression and an increase in time to 1 mm ST depression. In 15 patients, 24-hour ambulatory monitoring also revealed a decrease in episodes of silent ischemia. No significant side effects related to the study drug occurred.(ABSTRACT TRUNCATED AT 250 WORDS)

    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)

    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.

    Full Text Available Introduction: To compare the efficacy and tolerability of Ivabradine (IVA and Ranolazine (RAN in chronic angina patients. Materials and Methods: This was a follow-on, open-label trial conducted in a tertiary care hospital of Uttarakhand. Thirty patients each taking IVA 5 mg twice daily or RAN 500 mg twice daily were distributed to the respective groups. Patients were asked to fill a pretested questionnaire on frequency of anginal attacks and adverse reactions before and 2, 4 and 8 weeks after taking the respective medicines. Their blood pressure, heart rate and routine hematological and biochemical estimations were performed at baseline and after intervention. Results were statistically analyzed using different statistical tests, with P < 0.05 considered as significant. Results: There was no significant difference in the frequency of anginal attacks per week between the groups. The adverse drug reactions (ADRs reported in the IVA group were dizziness (30%, headache (16.6%, backache (16.6%, vertigo (13.3%, blurred vision (13.3%, muscle cramps (10%, arthralgia (10%, cough and dyspnea (6.6%, hypersensitivity rash (6.6%, fever (3.3% and nausea (3.3%. The ADRs in the RAN group were nausea (26.6%, dizziness (23.3%, vomiting (3.3%, constipation (3.3% and vertigo (3.3%. The blood pressure, heart rate and routine hematological and biochemical evaluations did not show any significant difference in the pre-post values. IVA significantly decreased the resting heart rate after eight weeks of intervention. Conclusions: Both antianginal agents appeared equiactive. However, RAN had a better safety and tolerability profile than IVA. Serum sickness-like reaction was an adverse event noticed with IVA, which needs causality establishment.

    Full Text Available Objectives: The clinical value of T wave inversion in lead aVL in diagnosing coronary artery disease (CAD remains unclear. This study aims to investigate the correlation between aVL T wave inversion and CAD in patients with chronic stable angina.Methods: Electrocardiograms (ECGs of 257 consecutive patients undergoing coronary angiography were analyzed. All patients had chronic stable angina. All patients with secondary T wave inversion had been excluded (66 patients. The remaining 191 patients constituted the study population. Detailed ECG interpretation and coronary angiographic findings were conducted by experienced cardiologists.Results: T wave inversion in aVL was identified in 89 ECGs (46.8% with definite ischemic Q-ST-T changes in different leads in 97 ECGs (50.8%. Stand alone aVL T wave inversion was found in 27 ECGs (14.1% while ischemic changes in other leads with normal aVL were identified in 36 ECGs (18.8%. The incidence of CAD was 86.3%. Single, two- and multi-vessel CAD were found in 38.8%, 28.5% and 32.7% of cases respectively. The prevalence of left main, left anterior descending, left circumflex and right coronary arteries were 4.7%, 61.2%, 29.3% and 44.5%, respectively. T wave inversion in aVL was found to be the only ECG variable significantly predicting mid segment left anterior descending artery (LAD lesions (Odds Ratio 2.93, 95% Confidence Interval 1.59-5.37, p=0.001.Conclusion: This study provides new information relating to T wave inversion in lead aVL to mid segment LAD lesions. Implication of this simple finding may help in bedside diagnosis of CAD typically mid LAD lesions. However, further studies are needed to corroborate this finding.

    Many studies show that ivabradine is effective for stable angina.This meta-analysis was performed to determine the effect of treatment duration and control group type on ivabradine efficacy in stable angina pectoris.Relevant articles in the English language in the PUBMED and EMBASE databases and related websites were identified by using the search terms "ivabradine," "angina," "randomized controlled trials," and "Iva." The final search date was November 2, 2015.Articles were included if they were published randomized controlled trials that related to ivabradine treatment of stable angina pectoris.Patients with stable angina pectoris were included.The patients were classified according to treatment duration (ivabradine and control groups, respectively. The ivabradine group had significantly longer exercise duration when they had been treated for at least 3 months, but not when treatment time was less than 3 months. Ivabradine significantly improved time to angina onset regardless of treatment duration. Control group type did not influence the effect of exercise duration (significant) or time to angina onset (significant).Compared with beta-blocker and placebo, ivabradine improved exercise duration and time to onset of angina in patients with stable angina. However, its ability to improve exercise duration only became significant after at least 3 months of treatment.

    The current American Heart Association/American College of Cardiology guidelines for patients with stable angina pectoris recommend β-blockers as the initial drug therapy for prevention of angina pectoris (class I B indication). Long-acting nitrates or calcium channel blockers should be prescribed for prevention of angina when β-blockers are contraindicated or not tolerated secondary to side effects (class I B indication). Long-acting nitrates or calcium channel blockers in combination with β-blockers should be prescribed for angina prevention when initial treatment with β-blockers is unsuccessful (class I B indication). Only sublingual nitroglycerin or nitroglycerin spray should be used for immediate relief of angina pectoris (class I B indication). Ranolazine with β-blockers can be used for prevention of angina when initial treatment with β-blockers is not successful (class IIa A indication). If angina persists despite treatment with β-blockers, long-acting nitrates and calcium channel blockers, we recommend the addition of ranolazine for prevention of stable angina pectoris. This editorial discusses the contemporary role of ranolazine in the management of patients with stable angina pectoris.

    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

    Medical treatment is the main clinical strategy for controlling patients with chronic stable angina and improving their quality of life (QoL). Ivabradine treatment on top of metoprolol decreases angina symptoms and improves QoL in patients with stable angina and coronary artery disease (CAD). This is a post hoc analysis (636 CAD patients given ivabradine/metoprolol free combination) of a prospective, noninterventional study that included 2403 patients with CAD and stable angina. Data were recorded at baseline at 1 and 4 months after inclusion. Patient QoL was assessed using the EQ-5D questionnaire. From baseline to study completion; ivabradine administration on top of metoprolol decreased heart rate (HR) from 80.8 ± 9.6 to 64.2 ± 6.2 bpm (P Ivabradine combined with metoprolol significantly decreased angina symptoms and use of nitroglycerin in patients with stable angina and CAD, leading to improved QoL. The benefits observed with this combination explain the high rate of adherence to treatment.

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.

    Symptoms play a crucial part in the formulation of medical diagnoses, yet the construction and interpretation of symptom narratives is not well understood. The diagnosis of angina is largely based on symptoms, but a substantial minority of patients diagnosed with "non-cardiac" chest pain go on to have a heart attack. In this ethnographic study our aims were to understand: (1) how the patients' accounts are performed or enacted in consultations with doctors; (2) the ways in which ambiguity in the symptom narrative is managed by doctors; and (3) how doctors reach or do not reach a diagnostic decision. We observed 59 consultations of patients in a UK teaching hospital with new onset chest pain who had been referred for a specialist opinion in ambulatory care. We found that patients rarely gave a history that, without further interrogation, satisfied the doctors, who actively restructured the complex narrative until it fitted a diagnostic canon, detaching it from the patient's interpretation and explanation. A minority of doctors asked about chest pain symptoms outside the canon. Re-structuring into the canonical classification was sometimes resisted by patients who contested key concepts, like exertion. Symptom narratives were sometimes unstable, with central features changing on interrogation and re-telling. When translation was required for South Asian patients, doctors considered the history less relevant to the diagnosis. Diagnosis and effective treatment could be enhanced by research on the diagnostic and prognostic value of the terms patients use to describe their symptoms.

    Although eliminating angina is a primary goal in treating patients with chronic coronary artery disease (CAD), few contemporary data quantify prevalence and severity of angina across US cardiology practices. The authors hypothesized that angina among outpatients with CAD managed by US cardiologists is low and its prevalence varies by site. Among 25 US outpatient cardiology clinics enrolled in the American College of Cardiology Practice Innovation and Clinical Excellence (PINNACLE) registry, we prospectively recruited a consecutive sample of patients with chronic CAD over a 1- to 2-week period at each site between April 2013 and July 2015, irrespective of the reason for their appointment. Eligible patients had documented history of CAD (prior acute coronary syndrome, prior coronary revascularization procedure, or diagnosis of stable angina) and ≥1 prior office visit at the practice site. Angina was assessed directly from patients using the Seattle Angina Questionnaire Angina Frequency score. Among 1257 patients from 25 sites, 7.6% (n = 96) reported daily/weekly, 25.1% (n = 315) monthly, and 67.3% (n = 846) no angina. The proportion of patients with daily/weekly angina at each site ranged from 2.0% to 24.0%, but just over half (56.3%) were on ≥2 antianginal medications, with wide variability across sites (0%-100%). One-third of outpatients with chronic CAD managed by cardiologists report having angina in the prior month, and 7.6% have frequent symptoms. Among those with frequent angina, just over half were on ≥2 antianginal medications, with wide variability across sites. These findings suggest an opportunity to improve symptom control.

    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.

  10. Selection of drug therapy in stable angina pectoris.

    Drug therapy in stable angina has two aims: the prevention of major cardiac events (such as unstable angina, myocardial infarction, or death) and the control of chest pain and transient myocardial ischemia. Given the low incidence of major cardiac events in patients with stable angina, primary preventive studies are scarce because they require a large sample size and long-term follow-up. Thus far, only aspirin and some lipid-lowering agents have been shown to be effective for this purpose. Antiischemic drugs reduce the imbalance between myocardial oxygen demand and supply, either by reducing oxygen consumption or by increasing coronary blood flow. The ideal approach would be to target drug therapy against the ischemia-inducing factor in each patient. The characteristics of anginal symptoms do not seem to help in selecting medical therapy, whereas a standard exercise test and a provocative test of coronary vasoconstriction may provide useful information in order to select patients who will preferentially respond to either a beta-blocker or a calcium antagonist. The combination of two or more anti-ischemic drugs does not seem to be any more effective than an adequately titrated monotherapy in reducing the occurrence of myocardial ischemia in individual patients. Combination therapy in stable coronary artery disease should include an individually selected and optimally titrated anti-ischemic agent and aspirin, with the addition of a lipid-lowering agent in patients with even mild hypercholesterolemia.

    The multifractal approach has been applied to temporal fluctuations of heartbeat (RR) intervals, measured in various regimes of physical activity (ergometric data), taken from healthy subjects and those having stable angina pectoris (SAP). The problem we address here is whether SAP changes multifractality observed in healthy subjects. The G-moment method is used to analyse the multifractal spectrum. It is observed that both sets of data characterize multifractality, but a different trend in multifractal behaviour is found for SAP disease, under pronounced physical activity.

    There is currently no blood-based test that can rapidly and objectively distinguish between chest pain which is initiated by increased myocardial oxygen demand (stable angina pectoris (SAP)) and chest pain initiated due to decreased coronary blood flow (unstable angina pectoris (UAP)). Since leukocytes play an active role in the progression of coronary artery disease (CAD), we hypothesize these can provide novel markers of SAP and UAP. Here we use a microarray of 82 cluster of differentiation (CD) antibodies (plus controls) to selectively immobilize peripheral blood mononuclear cells. We find that the pattern of leukocyte immobilization from patients with CAD significantly differs from healthy donors. Within the CAD group, 15 SAP patients exhibited significant (p<0.05) changes in 8 of 82 CD antibody spots compared to 19 age-matched healthy blood donors. An additional ten CD antigens differed between healthy donors and patients with UAP (p<0.05). Furthermore, seven CD antibody spots are significantly different between SAP and UAP patients. These preliminary data suggest it is now appropriate to undertake a larger clinical trial to test the hypothesis that these antibody microarrays can monitor the progression from SAP to UAP.

    Full Text Available Management of cardiac symptoms in myasthenia gravis (MG patients can be challenging. The aim of this report is to describe the safe use of ivabradine for stable angina in MG patients. A 48 y.o. woman, with MG diagnosis, presented stable angina. Therapies choices were reduced considering concomitant disease as well as previous and unsuccessful cardiologic managements. Ivabradine showed unexpected results. The patient presented an improvement of neurological and cardiac symptoms, bringing ivabradine as one more therapeutic option to similar patients. In this report we recommend ivabradine as an effective and safe drug for treatment of stable angina in MG patients.

    Angina pectoris is a common symptom imperiling patients' life quality. The aim of this study is to evaluate the efficacy and safety of acupuncture for stable angina pectoris. Clinical randomized-controlled trials (RCTs) comparing the efficacy of acupuncture to conventional drugs in patients with stable angina pectoris were searched using the following database of PubMed, Medline, Wanfang and CNKI. Overall odds ratio (ORs) and weighted mean difference (MD) with their 95% confidence intervals (CI) were calculated by using fixed- or random-effect models depending on the heterogeneity of the included trials. Total 8 RCTs, including 640 angina pectoris cases with 372 patients received acupuncture therapy and 268 patients received conventional drugs, were included. Overall, our result showed that acupuncture significantly increased the clinical curative effects in the relief of angina symptoms (OR=2.89, 95% CI=1.87-4.47, Pacupuncture therapy was superior to conventional drugs. Although there was no significant difference in overall effective rate relating reduction of nitroglycerin between two groups (OR=2.13, 95% CI=0.90-5.07, P=0.09), a significant reduction on nitroglycerin consumption in acupuncture group was found (MD=-0.44, 95% CI=-0.64, -0.24, Pacupuncture therapy than for traditional medicines (MD=2.44, 95% CI=1.64-3.24, Pacupuncture therapy were found. Acupuncture may be an effective therapy for stable angina pectoris. More clinical trials are needed to systematically assess the role of acupuncture in angina pectoris.

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.

MethodsPatients selected for PTCA/stenting were divided into two groups, one with stable angina pectoris (SAgroup, n--92) and one with unstable angina pectoris(UA group, n = 112). The outcomes of coronary angiographies (CAG), initial (30-d) success of theprocedure, and follow- up status in the two groupswere compared. Results Baseline characteristicswere similar, although the patients with unstablesymptoms more females ( P< 0.05), and had a higheraverage CCS class ( P< 0.05) and a higher incidenceof postinfarction angina ( P< 0. 01 ). The frequency of"complex" stenosis in patients with unstable anginawas higher than that of patients with stable angina,33% v 20% (P<0.01). A total of 309 vessels accepted the procedure; including 210 stents were successfully delivered to 156 patients. 143 and 67 stentswere implanted in the UA and SA group, respectively(P< 0.01 ). No major complication occurred in thetwo groups, except 12 patients experienced reoccurring chest pain initially, 9 in UA group v 3 in SAgroup ( P< 0.05). The averaged six - month follow -up status was compared too. Only 3 cases developedmyocardial infarction, including 2 patients with unstable angina. 12 and 16 reoccurring chest pains werefound in the two groups, respectively (13% in SAgroup vs 14% in UA group). There were no significant differences between groups in rates of clinicalrestenosis, follow- up angina class, or overall clinicalsuccess. Conclusions Patients with unstable anginareceiving PTCA/stenting have similar complication,restenosis, and initial and midterm success rate ascompared to patients with stable symptoms with strictcases select and careful preparation.

    This meta-analysis aimed to evaluate the efficacy of trimetazidine in combination with other anti-anginal drugs versus other anti-anginal drugs in the treatment of stable angina pectoris (SAP). Randomized controlled trials (RCTs) published in English and Chinese were retrieved from computerized databases: Embase, PubMed, and CNKI. Primary outcomes consist of clinical parameters (numbers of weekly angina attacks and nitroglycerin use) and ergometric parameters (time to 1mm ST-segment depression, and total work (in Mets) and exercise duration (in seconds) at peak exercise) in stable angina pectoris treated by trimetazidine or not. The quality of studies was evaluated using Jadad score. Data analysis of 13 studies was performed using Stata 12.0 software. Results showed that treatment of trimetazidine and other anti-anginal drugs was associated with a smaller weekly mean number of angina attacks (WMD=-0.95, 95%CI: -1.30 to -0.61, Z=5.39, Pangina pectoris. Sensitivity analysis was performed. Sub-group analysis showed that treatment duration was not a significant moderator and patients treated within 8 weeks and above 12 weeks had no difference in the outcomes addressed in this meta-analysis. No publish bias was detected. This meta-analysis confirms the efficacy of trimetazidine in the treatment of stable angina pectoris, in comparison with conventional antianginal agents, regardless of treatment duration.

    Percutaneous transluminal coronary angioplasty (PTCA) has higher complication and restenosis rates when performed in the setting of unstable angina. Balloon-expandable intracoronary stenting is a new technique with the potential to improve the results of PTCA. In order to determine whether stenting is associated with a poorer outcome in patients with unstable angina, we retrospectively examined our experience with the Palmaz-Schatz balloon-expandable intracoronary stent in 105 patients. Patients were divided into 2 groups on the basis of symptoms at the time of stent insertion: group I (n = 57) had stable angina pectoris, and group II (n = 48) had unstable angina defined as pain at rest despite antianginal therapy (Braunwald class II, III). Initial (30-d) and final (6-mo) success rates were defined as stent insertion without myocardial infarction, need for bypass surgery, death, and significant angina. Baseline characteristics were similar, although the patients with unstable symptoms were older, more likely to be female, and had a higher incidence of postinfarction angina. A total of 136 stents were successfully delivered to 97 target sites in 92% of patients. Major complications occurred in 4 patients (4%) and were due to subacute thrombosis in 3 of them. There were no differences in complication rates between patients receiving stents electively with stable vs. unstable symptoms (2% vs. 6%, p = NS). Six-mo. follow-up status was ascertained in 96% of patients and revealed overall clinical success in 83% with angiographic restenosis (> or = 50% stenosis) in 28% of patients. There were no significant differences between groups in rates of restenosis, follow-up angina class, or overall clinical success.(ABSTRACT TRUNCATED AT 250 WORDS)

    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.

    Dynamic analysis techniques may uncover abnormalities in heart rate (HR) behavior that are not easily detectable with conventional statistical measures. However, the applicability of these new methods for detecting possible abnormalities in HR behavior in various cardiovascular disorders is not well established. Conventional measures of HR variability were compared with short-term ( 11 beats, alpha2) fractal correlation properties and with approximate entropy of RR interval data in 38 patients with stable angina pectoris without previous myocardial infarction or cardiac medication at the time of the study and 38 age-matched healthy controls. The short- and long-term fractal scaling exponents (alpha1, alpha2) were significantly higher in the coronary patients than in the healthy controls (1.34 +/- 0.15 vs 1.11 +/- 0.12 [p angina pectoris have altered fractal properties and reduced complexity in their RR interval dynamics relative to age-matched healthy subjects. Dynamic analysis may complement traditional analyses in detecting altered HR behavior in patients with stable angina pectoris.

To compare antihypertensive, antianginal and antiischemic efficacy of β1-selective adrenoblockers (betaxolol and metoprolol tartrate in patients with arterial hypertension (HT of 1-2 degree associated with stable angina class II.Material and methods. 100 patients (aged 23-66 y.o. with HT associated with stable angina or without angina were involved in the study. Patients were randomized into 2 groups (G1 and G2. G1 patients were treated with betaxolol, and G2 patients – with metoprolol tartrate. Ambulatory BP and electrocardiogram monitoring, exercise stress-test, echocardiography, evaluating of respiratory function, blood analysis was performed initially and in 30 and 90 days of treatment.Results. Target BP level was reached in 44 (88% patients treated with betaxolol (average daily dose 10±4 mg. 34 patients of G1 took 10 mg daily. Target BP level was reached in 41 (82% patients treated with metoprolol tartrate (average daily dose 150±27 mg. 30 patients of G2 took 150 mg daily. Exercise tolerance increased and a number of ischemic ST segment depressions reduced significantly in both groups. There were no significant differences in antihypertensive, antianginal, and antiischemic efficacy between groups.Conclusion. Betaxolol advantage is an ability to maintain target BP level more than 24 hours. A possibility to take betaxolol once a day raises patient’s compliance with therapy.

    A 79-year-old man was diagnosed with sudden deafness. He had previously experienced a suspected episode of angina pectoris. At a local hospital, after 500 mg of hydrocortisone and 80 mg adenosine triphosphate (ATP) were administered, he became aware of chest discomfort. An electrocardiogram revealed serious ST-segment depressions. He was diagnosed with a non-ST elevated myocardial infarction (NSTEMI). Emergency coronary angiography revealed triple vessel disease, and the lesion was successfully stented. The mechanisms whereby the stable effort angina pectoris destabilized in this case were thought to include a reduction of the local blood flow because of an ATP product and probable thrombus formation in response to the administered steroids.

    This study evaluates transcoronary changes in neutrophil and platelet activation and conjugate formation in patients with angina pectoris secondary to coronary artery disease. We examined parameters of neutrophil and platelet activation as well as the neutrophil-platelet conjugate formation in patients who underwent diagnostic coronary angiography. Thirty-nine patients with chest pain referred for cardiac catheterization were studied (23 patients with unstable angina pectoris [UAP] and 16 with stable angina pectoris [SAP]). Before coronary angiography, blood samples were obtained simultaneously from the aortic root and coronary sinus to assess leukocyte (CD11b) and platelet (CD62P) activation and leukocyte-platelet conjugates. There was a 94% increase in CD62-expressing platelets from the aorta to the coronary sinus in patients with UAP compared with a 49% increase in patients with SAP. The percentage of neutrophil-platelet conjugates increased by 22% in patients with UAP compared with a 16% decrease in those with SAP (p <0.01). In contrast, monocyte-platelet binding across the coronary bed increased to a similar degree in both groups. This study demonstrates an increase in neutrophil-platelet conjugates across the coronary circulation in UAP, compatible with a higher activation state in both cell types.

    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.

    Percutaneous coronary intervention (PCI) has been extensively applied to repair the forward flow of diseased coronary artery and can achieve significant curative results. However, some patients with acute myocardial infarction (AMI) develop non-perfusion or poor perfusion of cardiac muscle tissue after PCI, which increases the incidence of cardiovascular events and the death rate. PCI can dredge narrowed or infarct-related artery (IRA) and thus induce full reperfusion of ischemic myocardium. It is found in practice that some cases of AMI still have no perfusion or poor perfusion in myocardial tissue even though coronary angiography suggests opened coronary artery after PCI, which increases the incidence of vascular events and mortality. Therefore, to explore the detailed mechanism of PCI in treating coronary microcirculation of patients with stable angina pectoris, we selected 140 patients with stable angina pectoris for PCI, observing the index of microcirculatory resistance (IMR) of descending branch and changes of myocardial injury markers and left ventricular systolic function, and made a subgroup analysis based on the correlation between clinical indexes, IMR and other variables of diabetic and non-diabetic patients, PCI-related and non-PCI-related myocardial infarction patients. The results suggest that IMR of anterior descending branch after PCI was higher compared to that before PCI, and the difference was significant (P less than 0.05); creatine kinase-MB (CK-MB), myohemoglobin and high sensitive troponin T were all increased after PCI, and the difference was also significant (P less than 0.05); brain natriuretic peptide (BNP) level became higher after PCI, with significant difference (P less than 0.05); left ventricular ejection fraction (LVEF) declined after PCI, and the difference before and after PCI was statistically significant (P less than 0.05). Moreover, subgroup analysis results of the three groups all demonstrated statistically significant

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

    Drugs for erectile dysfunction (ED) may be contraindicated with nitrates commonly used to treat patients with angina pectoris, and certain antianginal therapies may worsen ED. The American Heart Association and the Princeton Consensus Conference panel of experts recommend that patients with coronary artery disease and ED who experience angina pectoris undergo full medical evaluations to assess the cardiovascular risks associated with resuming sexual activity before being prescribed therapy for ED. Current antianginal therapies include β blockers, calcium channel blockers, short- and long-acting nitrates, and ranolazine, a late sodium current inhibitor. Short- and long-acting nitrates remain a contraindication with phosphodiesterase-5 inhibitors commonly used to treat patients with ED, and the benefits of the other antianginal therapies must be weighed against their effects on cardiovascular health and erectile function. In conclusion, patients with coronary artery disease and ED who wish to initiate phosphodiesterase-5 inhibitor therapy and need to discontinue nitrate therapy need treatment options that manage their angina pectoris effectively, maintain their cardiovascular health, and provide the freedom to maintain their sexual function.

    2007-01-01

    Objective: To investigate the relationship between serum resistin level and acute coronary syndrome (ACS) or stable angina pectoris (SAP). Methods: Sixty-five patients, with coronary artery disease, were enrolled and divided into three subgroups:acute myocardial infarction (AMI), unstable angina pectoris (UAP) and SAP, and 26 healthy people were recruited as controls in the cross-sectional study. Serum resistin levels were determined by ELISA (enzyme-linked immunosorbent assay), and WBC (white blood cell count), hsCRP (high sensitive C-reaction protein), CKmax (maximum ofcreatinkinase), CK-MBmax (maximum of isozyme of creatinkinase) and cTnImax (maximum oftroponin) were measured by standard laboratory methods. Results: The serum resistin levels were 4 folds higher in AMI patients, 2.43 folds in UAP patients and 1.12 folds in SAP patients than in the healthy controls (P<0.05). The resistin levels were also significantly different between AMI [(8.16±0.79) ng/ml], UAP [(5.59±0.75) ng/ml]and SAP [(3.45±0.56) ng/ml] groups (P<0.01); WBC, hsCRP, CKmax, CK-MBmax and cTnImax were significantly increased in AMI patients over UAP and SAP patients. Spearman analysis showed that serum resistin levels were positively correlated with WBC (r=0.412, P=0.046), hsCRP (r=0.427, P=0.037), CKmax, CK-MBmax and cTnImax (r=0.731, 0.678, 0.656; P<0.01). Conclusion:Serum resistin levels increased with inflammatory factors and myocardial impairment. The results suggest that human resistin might play an important role in the pathogenesis of atherosclerosis and AMI as an inflammatory factor.

    Full Text Available Abstract Background Exercise training has been shown to reduce angina and promote collateral vessel development in patients with coronary artery disease. However, the mechanism whereby exercise exerts these beneficial effects is unclear. There has been increasing interest in the use of whole genome peripheral blood gene expression in a wide range of conditions to attempt to identify both novel mechanisms of disease and transcriptional biomarkers. This protocol describes a study in which we will assess the effect of a structured exercise programme on peripheral blood gene expression in patients with stable angina, and correlate this with changes in angina level, anxiety, depression, and exercise capacity. Methods/Design Sixty patients with stable angina will be recruited and randomised 1:1 to exercise training or conventional care. Patients randomised to exercise training will attend an exercise physiology laboratory up to three times weekly for supervised aerobic interval training sessions of one hour in total duration. Patients will undergo assessments of angina, anxiety, depression, and peripheral blood gene expression at baseline, after six and twelve weeks of training, and twelve weeks after formal exercise training ceases. Discussion This study will provide comprehensive data on the effect of exercise training on peripheral blood gene expression in patients with angina. By correlating this with improvement in angina status we will identify candidate peripheral blood transcriptional markers predictive of improvements in angina level in response to exercise training.

    The Dutch College of General Practitioners' (Dutch acronym: NHG) practice guideline 'Stable angina pectoris' (second revision) provides clear guidelines for the diagnosis and treatment of patients who experience chest pains as a result of angina pectoris, especially if coronary artery disease is the underlying cause of the complaints. The practice guideline clearly indicates for which complaints the general practitioner should suspect angina pectoris and which information from the anamnesis, family history and risk factors can contribute to distinguishing between stable and unstable angina pectoris. However, the physical examination should not be omitted because this can provide important indications for coronary or pulmonary dysfunction. According to the practice guideline, the treatment policy is determined by the estimated risk of significant coronary artery disease. However, additional tests can be useful even in the case of a small risk, as these can reassure patients. The indications and contraindications for medicinal substances are clearly presented.

    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.

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.

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

    The effect of invasive percutaneous coronary procedures on complement activation has not been elucidated. We enrolled stable angina patients with elective percutaneous coronary intervention (SA-PCI, n=24), diagnostic coronary angiography (CA, n=52) and 23 patients with ST segment elevation myocardial infarction and primary PCI (STEMI-PCI). Complement activation products (C1rC1sC1inh, C3bBbP and SC5b-9) were measured on admission, 6 and 24h after coronary procedures. The alternative pathway product, C3bBbP significantly and reversibly increased 6h after elective PCI (baseline: 7.81AU/ml, 6h: 16.09AU/ml, 24h: 4.27AU/ml, p<0.01, n=23) and diagnostic angiography (baseline: 6.13AU/ml, 6h: 12.08AU/ml, 24h: 5.4AU/ml, p<0.01, n=52). Six hour C3bBbP values correlated with post-procedural CK, creatinine level and the applied contrast material volume (r=0.41, r=0.4, r=0.3, p<0.05, respectively). In STEMI-PCI, baseline C3bBbP level was higher, compared to SA-PCI or CA patients (11.33AU/ml vs. 7.81AU/ml or 6.13AU/ml, p<0.001). Similarly, the terminal complex (SC5b-9) level was already elevated at baseline compared to SA-PCI group (3.49AU/ml vs. 1.87AU/ml, p=0.011). Complement pathway products did not increase further after primary PCI. Elective coronary procedures induced transient alternative complement pathway activation, influenced by the applied contrast volume. In STEMI, the alternative complement pathway is promptly activated during the atherothrombotic event and PCI itself had no further detectable effect.

    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.

    The extent to which angina pectoris (AP) predicts secondary cardiovascular events beyond independent of measures of disease severity is unknown. We evaluated the association between AP frequency and secondary events in patients with stable coronary heart disease (CHD). We administered the Seattle Angina Questionnaire to 1,023 participants with stable CHD enrolled from September 2000 to December 2002 and followed for a median of 8.9 years. We used Cox proportional hazards to evaluate the association of AP frequency with death and subsequent hospitalization for AP, revascularization, myocardial infarction (MI), or heart failure. At enrollment, 633 (62%) participants reported no AP, 279 (27%) reported monthly AP, and 111 (11%) reported daily or weekly AP. During follow-up, 396 participants died, 204 were hospitalized for AP, 194 for revascularization, 140 for MI, and 188 for heart failure. Compared with participants without AP, participants with daily or weekly AP were more likely to be hospitalized for AP (hazard ratio [HR] 3.3; 95% confidence interval [CI] 2.3 to 4.7; p<0.001), revascularization (HR 2.0; 95% CI 1.3 to 2.9; p=0.001), or heart failure (HR 1.6; 95% CI 1.0 to 2.5; p=0.03) and more likely to die (HR 1.5; 95% CI 1.1 to 2.0; p=0.01). AP was not independently associated with MI (HR 1.3; 95% CI 0.8 to 2.3; p=0.29). After adjusting for demographics, co-morbidities, treadmill exercise capacity, ejection fraction, and inducible ischemia, frequency of AP remained independently associated with hospitalization for AP (HR 2.4; 95% CI 1.6 to 3.6; p<0.001), revascularization (HR 1.7; 95% CI 1.1 to 2.7; p=0.02), and death (HR 1.4; 95% CI 1.0 to 2.0; p=0.045). In conclusion, in outpatients with stable CHD, AP frequency predicts higher rates of secondary cardiovascular events and death, independent of objective measures of disease severity.

    We study the precise contribution of myocardial scintigraphy in the therapeutic management of stable coronary artery disease. Until recently, treatment was focused on revascularization, often by coronary angioplasty.Recent studies have challenged this practice by showing the absence of superiority of angioplasty compared to optimal medical therapy.The problem now is to define for each stable coronary artery disease, and individually, the best of both treatment options. In this spirit, the functional approach to coronary artery disease by myocardial perfusion scintigraphy is most interesting.The diagnostic performance, including sensitivity and negative predictive value, and the prognostic value of the technique are clearly established. Recent studies show that a therapeutic decision based on a functional approach to the patient is valid.We need to know this development in cardiology for best position in the multidisciplinary discussions, myocardial scintigraphy as a functional approach to stable coronary artery disease.

    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.

    Multislice computed tomography (CT) is an emerging technique for the non-invasive detection of coronary stenoses. While the diagnostic accuracy of 4-slice scanners was limited, 16-slice CT imagers showed promising results due to increased temporal and spatial resolution. These technical advances prompted us to evaluate the diagnostic performance of 64-slice CT coronary angiography in the detection of significant stenoses (defined as {>=} 50% luminal diameter reduction) versus invasive quantitative coronary angiography (QCA). Thirty-five patients with stable angina pectoris underwent CT coronary angiography performed with a 64-slice scanner (gantry rotation time 330 ms, individual detector width 0.6 mm) prior to conventional coronary angiography. Patients with heart rates >70 beats/min received 100 mg metoprolol orally. One hundred millilitres of contrast agent with an iodine concentration of 400 mgl/ml were injected at a rate of 5 ml/s into the antecubital vein. The CT scan was triggered with the bolus tracking technique. The sensitivity, specificity and the positive and negative predictive values of 64-slice CT were 99%, 96%, 78% and 99%, respectively, on a per-segment basis. The values obtained on a per-patient basis were 100%, 90%, 96% and 100%, respectively. When referral to catheterisation is questionable, CT coronary angiography may identify subjects with normal angiograms and consistently decrease the number of unnecessary invasive procedures.

    ackground Development of vulnerable lesions is not limited to the target lesions, but a pan-coronary process. Such lesions are identified by positive remodeling (intravascular ultrasound (IVUS) and complex lesions (angiography)). The prevalence of lesions with vulnerable characteristics in patients with stable angina was not well known. The purpose of the present study was to evaluate the relationship between coronary artery remodeling and incidence of angiographic complex lesions and its calcification in stable angina patients.Methods One hundred and sixty-one stable angina patients (95 males, aged (68±11) years) with 161 de novo target lesions were studied using pre-interventional IVUS. Remodeling index was defined as the lesion divided by reference vessel area; positive remodeling was defined as remodeling index >1.05. Besides the 161 target lesions, there were 613 angiographic lesions with >30% diameter stenoses, classified as complex or smooth. Multiple complexes were defined as more than one complex lesion in one patient. Stenoses of at least 70% were described as tight. Calcium arc area was used as a new method to quantify coronary calcification.Results Fifty-six patients had positive remodeling target lesion, while 105 did not. The overall number of lesions with a diameter stenoses >30% was similar in patients with or without positive remodeling, and the frequency of angiographically complex lesions was higher in positive remodeling patients, especially at non-target site. Calcium arc area was smaller in patients with positive remodeling.Conclusions Positive remodeling on intravascular ultrasound was associated with more complex lesions angiographic findings, especially at non target site. Positive remodeling was found less calcified in patients with stable angina.

    Objectives To evaluate the prognostic value of the coronary artery calcium (CAC) score in patients with stable angina pectoris (SAP) who underwent percutaneous coronary intervention (PCI). Methods A total of 334 consecutive patients with SAP who underwent first PCI following multi-slice computer tomography (MSCT) were enrolled from our institution between January 2007 and June 2012. The CAC score was calculated according to the standard Agatston calcium scoring algorithm. Complex PCI was defined as use of high pressure bal-loon, kissing balloon and/or rotablator. Procedure-related complications included dissection, occlusion, perforation, no/slow flow and emer-gency coronary artery bypass grafting. Main adverse cardiac events (MACE) were defined as a combined end point of death, non-fatal myo-cardial infarction, target lesion revascularization and rehospitalization for cardiac ischemic events. Results Patients with a CAC score>300 (n=145) had significantly higher PCI complexity (13.1%vs. 5.8%, P=0.017) and rate of procedure-related complications (17.2%vs. 7.4%, P=0.005) than patients with a CAC score≤300 (n=189). After a median follow-up of 22.5 months (4-72 months), patients with a CAC score≤300 differ greatly than those patients with CAC score>300 in cumulative non-events survival rates (88.9 vs. 79.0%, Log rank 4.577, P=0.032). After adjusted for other factors, the risk of MACE was significantly higher [hazard ratio (HR):4.3, 95%confidence inter-val (95%CI):2.4-8.2, P=0.038] in patients with a CAC score>300 compared to patients with a lower CAC score. Conclusions The CAC score is an independent predictor for MACE in SAP patients who underwent PCI and indicates complexity of PCI and proce-dure-related complications.

    International audience; Left precordial chest pain (LPCP) evokes above all angina. Eliminating a cardiac origin is then always the first priority. When cardiac causes are eliminated, non-cardiac causes are sought in order to avoid leaving patients with undiagnosed or undifferentiated chest pain. There is a myriad of non-cardiac causes ranging from heartburn, panic attacks, pleurisy, pulmonary embolism, pneumothorax, Tietze syndrome, bruises and fractures of the ribs, to spine meningioma, neur...

    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.

    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.

    Cervical angina has been widely reported as a cause of chest pain but remains underrecognized. This series demonstrates the varied clinical presentation of patients with cervical angina, the delay in diagnosis, and the extensive cardiac examinations patients with this condition typically undergo prior to a definitive diagnosis. Recognition of this condition in patients with acute chest pain requires a high index of suspicion and an awareness of the common presenting features and clinical findings of cervical angina.

    Full Text Available Przemyslaw KardasThe First Department of Family Medicine, Medical University of LodzBackground: A randomized, controlled trial was conducted in an outpatient setting to examine the effect of beta-blocker dosing frequency on patient compliance, clinical outcome, and health-related quality of life in patients with stable angina pectoris.Methods: One hundred and twelve beta-blockers-naive outpatients with stable angina pectoris were randomized to receive betaxolol, 20 mg once daily or metoprolol tartrate, 50 mg twice daily for 8 weeks. The principal outcome measure was overall compliance measured electronically, whereas secondary outcome measures were drug effectiveness and health-related quality of life.Results: The overall compliance was 86.5 ± 21.3% in the betaxolol group versus 76.1 ± 26.3% in the metoprolol group (p < 0.01, and the correct number of doses was taken on 84.4 ± 21.6% and 64.0 ± 31.7% of treatment days, respectively (p < 0.0001. The percentage of missed doses was 14.5 ± 21.5% in the once-daily group and 24.8 ± 26.4% in the twice-daily group (p < 0.01. The percentage of doses taken in the correct time window (58.6% vs 42.0%, p = 0.01, correct interdose intervals (77.4% v 53.1%, p < 0.0001, and therapeutic coverage (85.6% vs 73.7%, p < 0.001 were significantly higher in the once-daily group. Both studied drugs had similar antianginal effectiveness. Health-related quality of life improved in both groups, but this increase was more pronounced in the betaxolol arm in some dimensions.Conclusions: The study demonstrates that patient compliance with once-daily betaxolol is significantly better than with twice daily metoprolol. Similarly, this treatment provides better quality of life. These results demonstrate possible therapeutic advantages of once-daily over twice-daily beta-blockers in the treatment of stable angina pectoris.Keywords: patient compliance, quality of life, stable angina pectoris, randomized controlled trial

    The long-term risk associated with different coronary artery disease (CAD) presentations in women undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES) is poorly characterized. We pooled patient-level data for women enrolled in 26 randomized clinical trials. Of 11,577 women included in the pooled database, 10,133 with known clinical presentation received a DES. Of them, 5,760 (57%) had stable angina pectoris (SAP), 3,594 (35%) had unstable angina pectoris (UAP) or non-ST-segment-elevation myocardial infarction (NSTEMI), and 779 (8%) had ST-segment-elevation myocardial infarction (STEMI) as clinical presentation. A stepwise increase in 3-year crude cumulative mortality was observed in the transition from SAP to STEMI (4.9% vs 6.1% vs 9.4%; p <0.01). Conversely, no differences in crude mortality rates were observed between 1 and 3 years across clinical presentations. After multivariable adjustment, STEMI was independently associated with greater risk of 3-year mortality (hazard ratio [HR] 3.45; 95% confidence interval [CI] 1.99 to 5.98; p <0.01), whereas no differences were observed between UAP or NSTEMI and SAP (HR 0.99; 95% CI 0.73 to 1.34; p = 0.94). In women with ACS, use of new-generation DES was associated with reduced risk of major adverse cardiac events (HR 0.58; 95% CI 0.34 to 0.98). The magnitude and direction of the effect with new-generation DES was uniform between women with or without ACS (pinteraction = 0.66). In conclusion, in women across the clinical spectrum of CAD, STEMI was associated with a greater risk of long-term mortality. Conversely, the adjusted risk of mortality between UAP or NSTEMI and SAP was similar. New-generation DESs provide improved long-term clinical outcomes irrespective of the clinical presentation in women.

    Background Although the role of C-reactive protein (CRP) in predicting rapid progression of atherosclerotic lesions has been intensively studied in unstable coronary artery disease, the data from patients with stable angina (SA) are largely absent. The present study evaluated a middle-size patient cohort who underwent percutaneous coronary intervention (PCI) with stent implantation and follow-up coronary angiography (CAG) and tested the hypothesis that increased plasma level of high-sensitive CRP would indicate rapid progression of de novo non-target coronary artery lesions in Chinese patients with SA.Methods The study population comprised of 311 consecutive patients with chronic SA who underwent coronary stent implantation on initial admission and angiographic follow-up ((8.5±1.2) months). Rapid angiographic progression of non-target lesion was angiographically assessed and the patients were classified into two groups according to whether the progression existed or not. The relation of plasma CRP levels to the progression of atherosclerosis was investigated.Results Baseline demographic, clinical, and angiographic data were similar in patients with and without progression.Rapid angiographic progression of non-target lesions occurred in 136 patients (43.7%) at follow-up: 77 had a ≥10%diameter reduction of pre-existing stenosis ≥50%, 26 had a ≥30% diameter reduction of a pre-existing stenosis <50%, 64 developed a new lesion ≥30% in a previously normal segment, and 4 had progression of a lesion to total occlusion.Progression of non-target lesions was not associated with target lesion restenosis formation. High-sensitive CRP levels were markedly higher in progression patients than in non-progression ones (1.60 (0.80-3.46) mg/L vs. 0.96 (0.55-1.87)mg/L, P <0.001). Multivariate regression analysis showed that plasma CRP independently predicted rapid angiographic progression of non-target lesions (P=0.001). High-sensitive CRP levels above 1.32 mg

    This study determined the safety of deferring coronary revascularization based on a fractional flow reserve (FFR) value > or = 0.75 in a series of consecutive unselected coronary patients with moderate coronary lesions, including patients with unstable angina, myocardial infarction (MI), and/or positive noninvasive test findings. The study included 201 consecutive coronary patients (mean age 62 +/- 10 years; 65% men) with 231 lesions evaluated by FFR measurement for which revascularization was deferred based on a FFR value > or = 0.75. Lesions associated with a positive noninvasive test result were those located in an artery supplying a myocardial territory in which myocardial ischemia was demonstrated by a noninvasive test. Cardiac events (cardiac death, MI, revascularization) and Canadian Cardiovascular Society angina class were evaluated at follow-up. Indications for coronary angiography included unstable angina or MI (62%), stable angina (30%), or atypical chest pain (8%). Forty-four patients (22%) had > or = 1 coronary lesion associated with a positive noninvasive test result in which FFR was evaluated. Mean FFR value was 0.87 +/- 0.06 and mean lesion percent diameter stenosis was 41 +/- 8%. At 11 +/- 6 months of follow-up, cardiac events occurred in 20 patients (10%), and no significant differences were observed between patients with unstable angina or MI and those with stable angina (9% vs 13%, p = 0.44) or between patients with and without lesions associated with positive noninvasive test results (9% vs 10%, p = 1.00). At the end of follow-up, 88% of patients were asymptomatic in angina class 0 or I, with no differences across various groups. In conclusion, these results suggest that patients with moderate coronary lesions can be safely managed without revascularization on the basis of FFR measurements, irrespective of clinical presentation and/or presence of positive noninvasive test results.

    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.

    Heart rate plays a major role in myocardial ischemia. A high heart rate increases myocardial performance and oxygen demand and reduces diastolic time. Ivabradine reduces heart rate by inhibiting the If current of sinoatrial-node cells. In contrast to beta-blockers, ivabradine has no negative inotropic and lusitropic effect for a comparable heart rate reduction. Consequently, diastolic duration is increased with ivabradine compared to beta-blockers. This has potential consequences on coronary blood flow since compression of the vasculature by the surrounding myocardium during systole impedes flow and coronary blood flow is mainly diastolic. Moreover, ivabradine does not unmask alpha-adrenergic vasoconstriction and, unlike beta-blockers, maintains coronary dilation during exercise. In comparison with beta-blockers, ivabradine increases coronary flow reserve and collateral perfusion promoting the development of coronary collaterals. Ivabradine attenuates myocardial ischemia and its consequences even in the absence of heart rate reduction, possibly through reduced formation of reactive oxygen species. In conclusion, ivabradine differs from other anti-anginal agents by improving coronary blood flow and by additional pleiotropic effects. These properties make ivabradine an effective anti-anginal and anti-ischemic agent for the treatment of patients with coronary artery disease.

    Ludwig's angina is a rare infectious condition originating in the oropharyngeal region, most commonly from the teeth. The principal symptoms consist of cervical pain, dyspnea, dysphagia, symmetrical neck swelling and fever. Serious complications include respiratory collapses, mediastinitis, pleural empyema, pericarditis and pericardial tamponade, and may result in the death of the patient. The most useful investigations in patients with suspected Ludwig's angina are clinical assessment, a cervico-thoracic CT-scan to determine the extent of the lesions, microbiological examination and panoramic radiography to detect possible dental focuses of infection. Treatment consists of ensuring adequate ventilation by securing the upper airways, broad spectrum antibiotic therapy, eradication of the source of infection, and often early surgical decompression may be necessary. Rapid diagnosis and appropriate treatment can reduce the mortality rate to 10%.

    Coronary artery bypass grafting for patients with ischemic heart disease and hypothyroidism contains many controversies, and chronic renal failure causes perioperative water-electrolyte balance disorders. We experienced a case of unstable angina pectoris combined with hypothyroidism and chronic renal failure successfully treated by off-pump coronary artery bypass grafting (OPCAB). A 68-year-old man with a history of hypothyroidism and chronic renal failure was hospitalized with chest pain. Cardiac catheterisation revealed a 90% stenosis of segment 3, 11 and right ventricular (RV) branch, 75% stenosis of segment 6 and 50% stenosis of segment 5. His thyroid function was normal with orally administered levothyroxine. OPCAB was performed safely with hemodialysis until a day before operation and hemofiltration from a day after operation, and postoperative course was uneventful.

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

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

    Full Text Available David S Vadnais, Nanette K WengerDivision of Cardiology, Emory University School of Medicine, Atlanta, Georgia, USAAbstract: Chronic stable angina is an exceedingly prevalent condition with tremendous clinical, social, and financial implications. Traditional medical therapy for angina consists of beta-blockers, calcium channel blockers, and nitrates. These agents decrease myocardial oxygen demand and ischemia by reducing heart rate, lowering blood pressure, and/or optimizing ventricular loading characteristics. Unique in its mechanism of action, ranolazine is the first new antianginal agent approved for use in the US for chronic angina in over 25 years. By inhibiting the late inward sodium current (INa, ranolazine prevents pathologic intracellular calcium accumulation that leads to ischemia, myocardial dysfunction, and electrical instability. Ranolazine has been proven in multiple clinical trials to reduce the symptoms of angina safely and effectively and to improve exercise tolerance in patients with symptomatic coronary heart disease. These benefits occur without reduction in heart rate and blood pressure or increased mortality. Although ranolazine prolongs the QTc, experimental data indicate that ranolazine may actually be antiarrhythmic. In a large acute coronary syndrome clinical trial, ranolazine reduced the incidence of supraventricular tachycardia, ventricular tachycardia, new-onset atrial fibrillation, and bradycardic events. Additional benefits of ranolazine under investigation include reductions in glycosylated hemoglobin levels and improved left ventricular function. Ranolazine is a proven antianginal medication in patients with symptomatic coronary heart disease, and should be considered as an initial antianginal agent for those with hypotension or bradycardia.Keywords: chronic angina, myocardial ischemia, ranolazine, pharmacotherapy, antianginal, sodium current

  19. Comparison between National Institute for Health and Care Excellence (NICE) and European Society of Cardiology (ESC) guidelines for the diagnosis and management of stable angina: implications for clinical practice.

    Cardiologists in the UK use clinical practice guidelines from the National Institute for Health and Care Excellence (NICE) and from the European Society of Cardiology (ESC) to aid clinical decision-making. This review compares their recommendations regarding stable angina. NICE's diagnostic algorithm changed clinical practice in the UK, with most cardiologists moving from the exercise ECG towards newer, more accurate imaging modalities such as CT and MRI for diagnostic testing in patients with a low or medium probability of coronary artery disease (CAD), and directly to invasive coronary angiography in patients with a high probability of CAD. ESC guidelines are based around stress imaging for most patient groups. Both guidelines stress the importance of optimal medical therapy for patients with stable angina. NICE recommends coronary artery bypass graft surgery to improve prognosis for patients with left main stem and/or proximal 3-vessel disease, whereas the ESC also includes proximal left anterior descending artery disease among its indications for revascularisation to improve prognosis, particularly if there is evidence of myocardial ischaemia. The relation between disease complexity and 5-year clinical outcomes after revascularisation in patients with left main stem and/or 3-vessel CAD has been integrated into ESC guidance through the use of the SYNTAX score to aid treatment selection in this group of patients. Patients with stable angina who have disease involving the proximal left anterior descending artery are less likely to undergo myocardial revascularisation if they are managed according to NICE's guidance compared with the ESC's guidance.

    The relation between the amount of exercise-induced ischemia and alterations in left ventricular (LV) function and metabolism at rest was studied in 18 coronary patients with stable angina pectoris. An ischemic defect area score was computed from quantitative exercise thallium-201 (Tl-201) scintigraphy; this estimation of the amount of ischemic myocardium was used to classify the patients in group I (n = 8; score less than 15%, mean 6.7 +/- 2.5%) and II (n = 10; score greater than 15%; mean 27.2 +/- 8.9%). Hemodynamics and metabolism were studied in basal state. No patient had anginal pain during the study, and the extent of angiographic coronary artery disease (CAD) was comparable in the two groups. Heart rate, aortic pressure, coronary blood flow, and myocardial oxygen uptake were also similar in both groups. However, ejection fraction was reduced in group II (51 +/- 13 vs 63 +/- 5%; p less than 0.01) and LV relaxation was impaired as shown by the increase in time-constant of isovolumic pressure fall (55 +/- 16 vs 44 +/- 6 ms in group I; p less than 0.05); the LV end-diastolic pressure was also increased in group II (19 +/- 8 vs 10 +/- 4 mmHg in group l; p less than 0.05). Furthermore, in group II, myocardial lactate uptake was reduced (4 +/- 19 vs 30 +/- 29 mumole/min in group I; p less than 0.01) and the productions of alanine and glutamine were augmented (-7.5 +/- 4.4 vs -4.6 +/- 1.6 mumole/min in group I; p less than 0.05).

    The aim of this study was to evaluate clinical characteristics, procedural details, and outcomes of patients undergoing elective multivessel percutaneous coronary intervention (MV-PCI) in Europe. A total of 7113 patients with stable coronary artery disease and at least two major epicardial vessels with ≥ 70% stenosis were included in this analysis of the contemporary Euro Heart Survey PCI registry. Patients undergoing MV-PCI (n = 3376, 47.5%) were compared with those with single-vessel PCI (SV-PCI) (n = 3737, 52.5%). Patients with MV-PCI were more likely to have congestive heart failure, whereas those with SV-PCI more often suffered from noncardiac comorbidities. Hospital mortality (0.1% vs 0.3%) and the incidence of nonfatal postprocedural myocardial infarction (1.0% vs 0.7%) were low in patients with MV-PCI and SV-PCI. In the multivariate analysis, no significant difference in the incidence of hospital death (odds ratio (OR) 0.44, 95% confidence interval (CI) 0.15-1.27) could be observed between the two groups. However, the risk for postprocedural myocardial infarction (OR 1.57, 95% CI 0.93-2.67) tended to be higher among patients undergoing MV-PCI. Independent determinants for performing MV-PCI were age, comorbidities, and coronary anatomy. In Europe almost half of all patients with multivessel disease were treated with MV-PCI. Hospital complications were low, but a trend toward a higher rate of postprocedural myocardial infarctions was seen in patients with MV-PCI.

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.

    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.

    Lee, Hobart; Kim, Jeffrey; Tagmazyan, Karine

    2013-11-15

    Chronic obstructive pulmonary disease (COPD) is a common problem in primary care. COPD is diagnosed with spirometry only in clinically stable patients with a postbronchodilator forced expiratory volume in one second/forced vital capacity ratio of less than 0.70. All patients with COPD who smoke should be counseled about smoking cessation. Influenza and pneumococcal vaccinations are recommended for all patients with COPD. The Global Initiative for Chronic Obstructive Lung Disease assigns patients with COPD into four groups based on the degree of airflow restriction, symptom score, and number of exacerbations in one year. Pulmonary rehabilitation is recommended for patients in groups B, C, and D. Those in group A should receive a short-acting anticholinergic or short-acting beta2 agonist for mild intermittent symptoms. For patients in group B, long-acting anticholinergics or long-acting beta2 agonists should be added. Patients in group C or D are at high risk of exacerbations and should receive a long-acting anticholinergic or a combination of an inhaled corticosteroid and a long-acting beta2 agonist. For patients whose symptoms are not controlled with one of these regimens, triple therapy with an inhaled corticosteroid, long-acting beta2 agonist, and anticholinergic should be considered. Prophylactic antibiotics and oral corticosteroids are not recommended for prevention of COPD exacerbations. Continuous oxygen therapy improves mortality rates in patients with severe hypoxemia and COPD. Lung volume reduction surgery can improve survival rates in patients with severe, upper lobe-predominant COPD with heterogeneous emphysema distribution.

    BACKGROUND: Observer variability of dual-isotope myocardial perfusion imaging (MPI) with single photon emission computed tomography has rarely been investigated. The aim of our study was to evaluate the interpretive reproducibility with this technique. METHODS AND RESULTS: We report on 507 patients...... with known or suspected stable angina who were studied before coronary angiography. A 1-day thallium 201/technetium 99m sestamibi rest/stress MPI protocol was used. MPI was interpreted by 2 independent observers without knowledge of clinical data, using a 20-segment scoring model. By consensus, the overall...... rate of abnormal MPI was 49% (59% in men and 34% in women). The interobserver agreement for the whole group (kappa = 0.85) and for men and women separately (kappa = 0.86 and 0.82, respectively) was excellent with regard to the overall diagnosis (normal, reversible, or fixed defects) as well as left...

    Aim: In patients with stable angina pectoris both morphological and functional information about the coronary artery tree should be present before revascularization therapy is performed. High accuracy was shown for spiral computed tomography (MDCT) angiography acquired with a 64-slice CT scanner compared to invasive coronary angiography (ICA) in detecting ''obstructive'' coronary artery disease (CAD). Gated myocardial SPECT (MPI) is an established method for the noninvasive assessment of functional significance of coronary stenoses. Aim of the study was to evaluate the combination of 64-slice CT angiography plus MPI in comparison to ICA plus MPI in the detection of hemodynamically relevant coronary artery stenoses in a clinical setting. Patients, methods: 30 patients (63 {+-} 10.8 years, 23 men) with stable angina (21 with suspected, 9 with known CAD) were investigated. MPI, 64-slice CT angiography and ICA were performed, reversible and fixed perfusion defects were allocated to determining lesions separately for MDCT angiography and ICA. The combination of MDCT angiography plus MPI was compared to the results of ICA plus MPI. Results: Sensitivity, specificity, negative and positive predictive value for the combination of MDCT angiography plus MPI was 85%, 97%, 98% and 79%, respectively, on a vessel-based and 93%, 87%, 93% and 88%, respectively, on a patient-based level. 19 coronary arteries with stenoses =50% in both ICA and MDCT angiography showed no ischemia in MPI. Conclusion: The combination of 64-slice CT angiography and gated myocardial SPECT enabled a comprehensive non-invasive view of the anatomical and functional status of the coronary artery tree.

    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 pharmacological treatment of chronic obstructive pulmonary disease (COPD) can significantly improve quality of life by reducing exacerbations, dyspnea and exercise intolerance, thereby limiting the degree of handicap and improving daily activities. Recently, large randomised trials showed that some treatments can alter the decline in FEV1, which was previously only accessible to smoking cessation, and maybe reduce mortality. Bronchodilators are the first-line pharmacological treatment of COPD. Their clinical efficacy cannot be predicted by the inconstant changes in FEV(1.) Their main mechanism of action is the reduction in lung hyperinflation. Theophylline has a lower efficacy/tolerance ratio than inhaled bronchodilators. In symptomatic patients with FEV1 regeneration are also being studied. Medications must be associated with non-pharmacological measures (including help towards smoking cessation, education, exercise training...). Systemic manifestations of COPD must also be taken into account.

    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.

    Despite increasing pharmacological and mechanical treatment options, ischemic heart disease continues to be associated with considerable patient mortality and morbidity. The estimates of the direct and indirect costs associated with chronic stable angina amount to billions of dollars. Given the epidemiological and economic magnitude of the problem, the need for more effective therapies is self-evident. Based on current guidelines, the management of ischemic heart disease has progressively broadened to include risk factor modification, patient education, and pharmacological therapy. The latter includes i) classic antianginal agents such as beta-blockers, calcium antagonists, and nitrates, and ii) drugs for secondary prevention, such as aspirin, clopidogrel, statins, and angiotensin-converting enzyme inhibitors. Tailoring therapy to individual needs has become even more challenging because of the marked changes in the clinical profile of patients with chronic ischemic heart disease. Compared with the past, today's patients tend to be older, to have undergone revascularization procedures, and to frequently have associated illnesses, including heart failure and diabetes. Significant progress has been made in recent years in understanding the role of cardiac energy metabolism in the pathogenesis of myocardial ischemia. A better understanding of metabolic derangements associated with ischemia and reperfusion is translating into innovative therapeutic approaches. Optimization of cardiac energy metabolism is based on promoting cardiac glucose oxidation. This has been proved to enhance cardiac function and protect myocardial tissue against ischemia-reperfusion injury. A new class of metabolic agents, known as the 3-ketoacyl coenzyme A thiolase inhibitors (trimetazidine), is able to elicit an increase in glucose and lactate combustion secondary to partial inhibition of fatty acid oxidation, producing clinical benefits in patients with ischemic heart disease.

    Stable in vivo mapping and modulation of the same neurons and brain circuits over extended periods is critical to both neuroscience and medicine. Current electrical implants offer single-neuron spatiotemporal resolution but are limited by such factors as relative shear motion and chronic immune responses during long-term recording. To overcome these limitations, we developed a chronic in vivo recording and stimulation platform based on flexible mesh electronics, and we demonstrated stable multiplexed local field potentials and single-unit recordings in mouse brains for at least 8 months without probe repositioning. Properties of acquired signals suggest robust tracking of the same neurons over this period. This recording and stimulation platform allowed us to evoke stable single-neuron responses to chronic electrical stimulation and to carry out longitudinal studies of brain aging in freely behaving mice. Such advantages could open up future studies in mapping and modulating changes associated with learning, aging and neurodegenerative diseases.

    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.

    Asthma is a chronic inflammatory disorder of the airways related to the obstruction of reversible airflow. Asthma presents as recurrent attacks of cough and dyspnea. Poor control causes recurrent admissions to the ICU, and mortality is related to poor drug compliance and follow-up. Angina pectoris is a syndrome of recurrent chest discomfort related to myocardial ischemia. The presence of these two disorders rarely has been reported. We reported a 12-year-old boy who was referred with exacerbation of asthma and developed angina pectoris during hospitalization. He had labored breathing and diffuse wheezing. During treatment of the asthma, the patient developed severe chest pain due to shunt formation and coronary hypoxia, caused by the sole administration of ventolin, since oxygen had been disconnected. After receiving appropriate therapy, both his asthma and angina recovered, and, to date, he has not experienced angina pectoris again.

    Stable angina pectoris affects 2-4 % of the population in Western countries and entails an annual risk of death and nonfatal myocardial infarction of 1-2 % and 3 %, respectively. Heart rate (HR) is linearly related to myocardial oxygen consumption and coronary blood flow, both at rest and during stress. HR reduction is a key target for the prevention of ischemia/angina and is an important mechanism of action of drugs which are recommended as first line therapy for the treatment of angina in clinical guidelines. However, many patients are often unable to tolerate the doses of beta blocker or non-dihydropyridine calcium antagonists required to achieve the desired symptom control. The selective pacemaker current inhibitor ivabradine was developed as a drug for the management of patients with angina pectoris, through its ability to reduce HR specifically. The available data suggest that ivabradine is a well-tolerated and effective anti-anginal agent and it is recommended as a second-line agent for relief of angina in guidelines. However, recent clinical trials of ivabradine have failed to show prognostic benefit and have raised potential concerns about safety. This article will review the available evidence base for the current role of ivabradine in the management of patients with symptomatic angina pectoris in the context of stable coronary artery disease.

    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.

    BACKGROUND: According to most current guidelines, stable angina pectoris patients with a high probability of having coronary artery disease can be reliably identified clinically. OBJECTIVES: To examine the reliability of clinical evaluation with or without an at-rest electrocardiogram (ECG......) in patients with a high probability of coronary artery disease. PATIENTS AND METHODS: A prospective series of 357 patients referred for coronary angiography (CA) for suspected stable angina pectoris were examined by a trained physician who judged their type of pain and Canadian Cardiovascular Society grade...... of pain. Pretest likelihood of disease was estimated, and all patients underwent myocardial perfusion scintigraphy (MPS) followed by CA an average of 78 days later. For analysis, the investigators focused on the approximate groups of patients with more severe disease, ie, typical angina (n=187), Canadian...

  17. [Diagnostics and therapy of chronic stable coronary artery disease : new guidelines of the European Society of Cardiology].

    2014-12-01

    The European Society of Cardiology (ESC) guidelines on the management of stable coronary artery disease published in 2013 give practical recommendations for diagnostics and therapy. The approach depends on the clinical picture and symptoms of the patient, the severity and extent of ischemia, the degree and location of coronary stenoses, additional cardiac findings and finally on non-cardiac comorbidities. The selection of suitable diagnostic tools is based on the tabulated pretest probability for the presence of coronary artery disease which plays an important and central role in the diagnostic algorithm. An invasive approach is recommended only in patients with severe angina, i.e. a Canadian Cardiovascular Society (CCS) angina grading scale of ≥ CCS3 or in patients who are at high risk for death or myocardial infarction based on the results of the test used for detection of ischemia. Detailed therapeutic recommendations are given for medicinal and interventional or surgical therapy. Medicinal therapy includes drugs both for relief of symptoms and prevention of cardiovascular events. Recommendations are also given for the use of new antianginal drugs. A PCI is only indicated in vessels causing ischemia which can be verified by using fractional flow reserve measurements. The indications for PCI now also include patients with a low SYNTAX score and multivessel disease or left main stenosis; however, the optimal strategy should be individually determined in heart team discussions.

    Full Text Available ABSTRACT: BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD is the most common chronic lung disease causing chronic respira tory disability in majority of people. There is now strong scientific evidence to recommend the application of pulmonary rehabilitation programs in chronic lung diseases. MATERIALS AND METHODS: 28 patients of stable COPD were enrolled for this study. Patients were randomi zed into two groups, one group received pulmonary rehabilitation programme plus standard medic al therapy (SMT (n=15 designated as case and other that received standard medical th erapy alone (n=13, designated as control. OBSERVATIONS AND RESULT: There was no significant difference in changes in Forced Vital Capacity (FVC, Forced expiratory volume in 1 st second (FEV 1 and percentage predicted FEV 1 /FVC (% predicted after the pulmonary rehabilitatio n programme, when compared between cases and controls. However after pulmonary rehabilitation programme the change in Borg's scale score for post-exercise dyspnoea, when c ompared between cases and controls showed statistically significant difference. Also t he St. George’s Respiratory Questionnaire (SGRQ-symptoms score in patients receiving pulmonary rehabilitation programmes plus Standard Medical treatment, when compared after reh abilitation programme was significantly greater than patients receiving only standard medica l treatment. CONCLUSION : Pulmonary rehabilitation programme improved exercise capacity, s ymptoms and health related quality of life without any significant change in pulmonary fun ctions. So, comprehensive pulmonary rehabilitation programme should be considered for ov erall management of chronic obstructive pulmonary disease along with recommended pharmacologi cal treatment.

    Full Text Available Kumiko Hattori, Takeo Ishii, Takashi Motegi, Yuji Kusunoki, Akihiko Gemma, Kozui Kida Department of Pulmonary Medicine and Oncology; Respiratory Care Clinic, Nippon Medical School, Tokyo, Japan Background: High-sensitivity cardiac troponin T (hs-cTnT in serum is a useful marker of acute myocardial injury, yet information is limited in patients with chronic obstructive pulmonary disease. We aimed to explore the association between hs-cTnT levels and cardiac and pulmonary dysfunction in patients with stable chronic obstructive pulmonary disease and at-risk individuals. Methods: We examined community-dwelling adults with/without chronic obstructive pulmonary disease, with a life-long smoking history, current symptoms of dyspnea during exertion, prolonged coughing, and/or sputum. Serum hs-cTnT concentrations were measured, and subjects underwent pulmonary function tests, high-resolution computed tomography of the chest, an echocardiogram, and a 6-minute walking test. Results: Eighty-six stable patients were identified (mean age 65.5 years; predicted forced expiratory volume in 1 second [FEV1% predicted] 75.0%. Their overall mean hs-cTnT level was 0.008 ng/mL. Logarithmically transformed hs-cTnT levels significantly and positively correlated with age, smoking index, serum high-sensitivity C-reactive protein levels, right ventricle systolic pressure, low attenuation area percentage, and brain natriuretic peptide levels (range r=0.231–0.534, P=0.000 to P=0.042. Further, logarithmically transformed hs-cTnT values significantly and negatively correlated with forced vital capacity, FEV1% predicted, diffusion capacity, arterial oxygen tension, and 6-minute walking distance (range r= -0.482 to -0.377, P=0.000 to P=0.002. Multivariate analyses showed that hs-cTnT values varied independently according to the following three parameters: high-sensitivity C-reactive protein levels (B=0.157, ß=0.450, t=3.571, P=0.001, age (B=0.008, ß=0.352, t=2.789, P=0

    Full Text Available Abstract Introduction Menstruation is commonly associated with migraine and irritable bowel but is rarely correlated with angina or myocardial ischaemia. Only a small number of cases have been reported suggesting a link between menstruation and myocardial ischaemic events. Case presentation A case of menstruation angina is reported in order to raise awareness of this association. A 47-year-old South Asian woman presented with recurrent chest pains in a monthly fashion coinciding with her menstruations. Each presentation was associated with troponin elevation. Angioplasty failed to resolve her symptoms but she eventually responded to hormonal therapy. Conclusions The possibility of menstruation angina should always be taken into account in any female patients from puberty to menopause presenting with recurrent chest pains. This can allow an earlier introduction of hormonal therapy to arrest further myocardial damage.

    AIMS: Here, the aim is to assess long-term clinical variation (CV) of N-terminal pro-brain natriuretic peptide (NT-proBNP) in stable chronic heart failure (CHF) patients. The proposed use of NT-proBNP for monitoring of CHF patients will require accurate information about long-term CV of the peptide...... months after the second follow-up were included. A total of 78 patients fulfilled the criteria, and year-to-year CV was calculated to 30% (median) (range: 0-111%) (% changes range: -87 to 397%). Log transformation of NT-proBNP (skewed to the right) reduced the year-to-year CV to 4.7% (range: 0......-22%) (% changes range: -18 to 38%). CONCLUSION: Long-term CV of plasma concentrations of NT-proBNP in stable CHF patients is 30%, but the variation is substantial. Therefore, high long-term CV of NT-proBNP does not necessarily carry prognostic significance within the subsequent 12 months. Plasma concentrations...

    Full Text Available Background: The protease-antiprotease hypothesis proposes that inflammatory cells and oxidative stress in chronic obstructive pulmonary disease (COPD produce increased levels of proteolytic enzymes (neutrophil elastase, matrix metalloproteinases [MMP] which contribute to destruction of parenchyma resulting in progressive decline in forced expiratory volume in one second. Doxycycline, a tetracycline analogue, possesses anti-inflammatory properties and inhibits MMP enzymes. Objectives: To assess the effect of 4 weeks doxycycline in a dose of 100 mg once a day in patients of moderate to severe COPD with stable symptoms. Methods : In an interventional, randomized, observer-masked, parallel study design, the effect of doxycycline (100 mg once a day for 4 weeks was assessed in patients of COPD having stable symptoms after a run-in period of 4 weeks. The study participants in reference group did not receive doxycycline. The parameters were pulmonary functions, systemic inflammation marker C-reactive protein (CRP, and medical research council (MRC dyspnea scale. Use of systemic corticosteroids or antimicrobial agents was not allowed during the study period. Results: A total of 61 patients completed the study (31 patients in doxycycline group and 30 patients in reference group. At 4 weeks, the pulmonary functions significantly improved in doxycycline group and the mean reduction in baseline serum CRP was significantly greater in doxycycline group as compared with reference group. There was no significant improvement in MRC dyspnea scale in both groups at 4 weeks. Conclusion: The anti-inflammatory and MMP-inhibiting property of doxycycline might have contributed to the improvement of parameters in this study.

    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

    The review is devoted to exercise tests (ET) potential in patients with different forms of coronary heart disease (CHD) exacerbation and suspected unstable angina. It is well known that unstable angina untreated pharmacologically is a contraindication for ET. Of interest in clinical practice is diagnosis, risk assessment and treatment policy in patients with chest pain. The main focus is on ET conduction in unstable angina suspects with low and intermediate risk, on safety and validity of ET conduction in these patients.

    Variant angina is a form of angina pectoris that shows transient ST-segment elevation on electrocardiogram during an attack of chest pain. Ischemic episodes of variant angina show circadian variation and often occur at rest from midnight to early morning. Ischemic episodes also occur during mild exercise in the early morning. However, they are not usually induced by strenuous exercise in the afternoon. Other important clinical features of variant angina include the high frequency of asymptomatic ischemic episodes and the syncope that sometimes occur during the ischemic episodes. Syncope is due to severe arrhythmias, including ventricular tachycardia, ventricular fibrillation, and high-degree atrioventricular block. Coronary artery spasm is the mechanism of ischemic episodes in variant angina. The incidence of coronary artery spasm shows a racial difference and is higher in Japanese than in Caucasians. Coronary arteriograms are normal or near-normal in most Japanese patients with variant angina. Deficient basal release of nitric oxide (NO) due to endothelial dysfunction, and enhanced vascular smooth muscle contractility with the involvement of the Rho/Rho-kinase pathway are reported to play important roles in the pathogenesis of coronary artery spasm. Other precipitating factors of coronary artery spasm include imbalance in autonomic nervous activity, increased oxidative stress, chronic low-grade inflammation, magnesium deficiency, and genetic susceptibility. The genetic risk factors associated with coronary artery spasm include gene polymorphisms of endothelial NO synthase (NOS), paraoxonase, and other genes. Calcium channel blockers are extremely effective in preventing coronary spasm. The long-acting nitrate, nicorandil, and Rho-kinase inhibitor are also useful for inhibiting coronary artery spasm. Because variant angina can lead to acute myocardial infarction, fatal arrhythmias, and sudden death, early treatment is important. The prognosis of patients with

    Nitrates are potent venous dilators and anti-ischemic agents. They are widely used for the relief of chest pain and pulmonary congestion in patients with acute coronary syndromes and heart failure. Nitrates, however, do not reduce mortality in patients with acute coronary syndromes. Combination of nitrates and hydralazine when given in addition to beta-blockers and angiotensin-converting enzyme (ACE) inhibitors reduce mortality and heart failure hospitalizations in patients with heart failure due to left ventricular systolic dysfunction who are of African-American origin. Side effects during nitrate therapy are common but are less well described in the literature compared with the reported side effects in patients with stable angina pectoris. The reported incidence of side effects varies highly among different studies and among various disease states. Headache is the most commonly reported side effect with an incidence of 12% in acute heart failure, 41-73% in chronic heart failure, 3-19% in unstable angina and 2-26% in acute myocardial infarction. The reported incidence of hypotension also differs: 5-10% in acute heart failure, 20% in chronic heart failure, 9% in unstable angina and < 1-48% in acute myocardial infarction, with the incidence being much higher with concomitant nitrate therapy plus angiotensin-converting enzyme inhibitors. Reported incidence of dizziness is as low as 1% in patients with acute myocardial infarction to as high as 29% in patients with heart failure. Severe headaches and/or symptomatic hypotension may necessitate discontinuation of nitrate therapy. Severe life threatening hypotension or even death may occur when nitrates are used in patients with acute inferior myocardial infarction associated with right ventricular dysfunction or infarction, or with concomitant use of phosphodiesterase-5 inhibitors or N-acetylcysteine. Despite the disturbing observational reports in the literature that continuous and prolonged use of nitrates may lead to

    The Finnish Medical Society Duodecim initiated and managed the update of the Finnish national guideline for chronic obstructive pulmonary disease (COPD). The Finnish COPD guideline was revised to acknowledge the progress in diagnosis and management of COPD. This Finnish COPD guideline in English language is a part of the original guideline and focuses on the diagnosis, assessment and pharmacotherapy of stable COPD. It is intended to be used mainly in primary health care but not forgetting respiratory specialists and other healthcare workers. The new recommendations and statements are based on the best evidence available from the medical literature, other published national guidelines and the GOLD (Global Initiative for Chronic Obstructive Lung Disease) report. This guideline introduces the diagnostic approach, differential diagnostics towards asthma, assessment and treatment strategy to control symptoms and to prevent exacerbations. The pharmacotherapy is based on the symptoms and a clinical phenotype of the individual patient. The guideline defines three clinically relevant phenotypes including the low and high exacerbation risk phenotypes and the neglected asthma-COPD overlap syndrome (ACOS). These clinical phenotypes can help clinicians to identify patients that respond to specific pharmacological interventions. For the low exacerbation risk phenotype, pharmacotherapy with short-acting β2 -agonists (salbutamol, terbutaline) or anticholinergics (ipratropium) or their combination (fenoterol-ipratropium) is recommended in patients with less symptoms. If short-acting bronchodilators are not enough to control symptoms, a long-acting β2 -agonist (formoterol, indacaterol, olodaterol or salmeterol) or a long-acting anticholinergic (muscarinic receptor antagonists; aclidinium, glycopyrronium, tiotropium, umeclidinium) or their combination is recommended. For the high exacerbation risk phenotype, pharmacotherapy with a long-acting anticholinergic or a fixed combination

    Thirty caucasian male patients with stable angina were investigated in two groups of nine and one group of 12. Nine normal subjects were also studied. Patients in the first group (on no treatment) underwent symptom-limited exercise electrocardiography at 0800, 1200, and 1600 hours on the same day. Their heart rates and ST segment displacements at 1600 hours were significantly greater than at 0800 hours and the same phenomenon was seen in the second group who had been receiving propranolol 40 mg four times a day. A similar effect was noted for ST segment displacement but not for heart rate in the third group (on no treatment) tested at 0800 hours and 1600 hours on separate days, two to three weeks apart. Normal control subjects showed no diurnal variation in heart rate and their heart rate responses at 1600 hours were reduced by propranolol. The observations show a circadian variation in the ST segment response to exercise in patients with angina and a possible training effect on heart rate with multiple exercise testing on the same day. This variation is associated with a reduction in vagal parasympathetic tone to the heart and should be taken into account in the assessment of patients with angina and in particular when comparing responses to treatment.

    Alongside the remarkable advances in medical and invasive therapies for the treatment of ischemic heart disease, an increasing number of patients with advanced coronary artery disease unsuitable for revascularization continue to suffer from angina pectoris despite optimal medical therapy. Patients with chronic angina have poor quality of life and increased levels of anxiety and depression. A considerable number of innovative therapeutic modalities for the treatment of chronic angina have been investigated over the years; however, none of these therapeutic options has become a standard of care, and none are widely utilized. Current treatment options for refractory angina focus on medical therapy and secondary risk factor modification. Interventions to create increased pressure in the coronary sinus may alleviate myocardial ischemia by forcing redistribution of coronary blood flow from the less ischemic subepicardium to the more ischemic subendocardium, thus relieving symptoms of ischemia. Percutaneous, transvenous implantation of a balloon expandable, hourglass-shaped, stainless steel mesh in the coronary sinus to create a fixed focal narrowing and to increase backwards pressure, may serve as a new device-based therapy destined for the treatment of refractory angina pectoris.

    OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation that leads to excessive remodeling of the lung extracellular matrix (ECM), resulting in release of protein fragments (neo-epitopes) to the blood. Serological markers assessing this have previously been...... associated with exacerbations of COPD. However, characterization of these in individuals with clinically stable COPD is lacking. The aim of this study was to characterize the collagen remodeling in stable COPD by the serological assessment of neo-epitopes. DESIGN AND METHODS: Sixty-eight subjects...... with clinically stable COPD were included into the study at baseline, and 27 came back for a four weeks follow-up visit.

    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.

    To assess the clinical significance of iodine-123 beta-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) single photon emission computed tomography (SPECT), the predictive value of BMIPP imaging in patients with angina pectoris was evaluated. One hundred seventy-four patients who underwent BMIPP imaging in our institution were aged 61.8{+-}11 years. One hundred thirty-five patients had stable angina and 39 had unstable angina at the time of examination. Patients with previous myocardial infarction or myocardial disorders were excluded. Early and delayed images were acquired in BMIPP SPECT, and the images were analyzed visually. Cardiac events were classified into hard and soft events: the former consisted of cardiac death and nonfatal myocardial infarction, and the latter included coronary revascularization and heart failure. The findings of BMIPP imaging were normal in 82 patients and abnormal in 92. During follow-up of 15.5{+-}9.5 months, hard events were observed in 4 patients and soft events in 53. In patients with normal BMIPP imaging, soft events were observed in nine patients, but no hard event was encountered. Furthermore, in patients with both normal BMIPP and stress thallium imagings, no cardiac event was observed during 2 years. In contrast, 4 hard events and 44 soft events occurred in patients with abnormal BMIPP imaging. Patients with abnormal BMIPP imaging had a higher incidence of soft events than those with normal BMIPP imaging, regardless of the type of angina (16/62 vs 3/73, p<0.0005 for stable angina; 28/30 vs 6/9, p<0.0001 for unstable angina). The finding of BMIPP imaging correlates well with the mid-term prognosis of patients with angina pectoris. Since BMIPP SPECT is performed without stress to the patient, this imaging modality is important in evaluating patients with stable or unstable angina. (author)

    Full Text Available OBJECTIVE: The potential influence of magnesium on exercise performance is a subject of increasing interest. Magnesium has been shown to have bronchodilatatory properties in asthma and chronic obstructive pulmonary disease patients. The aim of this study was to investigate the effects of acute magnesium IV loading on the aerobic exercise performance of stable chronic obstructive pulmonary disease patients. METHODS: Twenty male chronic obstructive pulmonary disease patients (66.2 + 8.3 years old, FEV1: 49.3+19.8% received an IV infusion of 2 g of either magnesium sulfate or saline on two randomly assigned occasions approximately two days apart. Spirometry was performed both before and 45 minutes after the infusions. A symptom-limited incremental maximal cardiopulmonary test was performed on a cycle ergometer at approximately 100 minutes after the end of the infusion. ClinicalTrials.gov: NCT00500864 RESULTS: Magnesium infusion was associated with significant reductions in the functional residual capacity (-0.41 l and residual volume (-0.47 l, the mean arterial blood pressure (-5.6 mmHg and the cardiac double product (734.8 mmHg.bpm at rest. Magnesium treatment led to significant increases in the maximal load reached (+8 w and the respiratory exchange ratio (0.06 at peak exercise. The subgroup of patients who showed increases in the work load equal to or greater than 5 w also exhibited significantly greater improvements in inspiratory capacity (0.29 l. CONCLUSIONS: The acute IV loading of magnesium promotes a reduction in static lung hyperinflation and improves the exercise performance in stable chronic obstructive pulmonary disease patients. Improvements in respiratory mechanics appear to be responsible for the latter finding.

    Panic attacks are a frequently cited cause of noncardiac chest pain. A strict separation of the internist's job (i. e., ruling out an "organic" cause of the patient's complaints) from the psychiatrist's job (e. g., diagnosing and treating panic disorder if present) may not always be the most efficient way of diagnostic work-up. We present the case of a 56-year-old female referred to our institution for elective coronary arteriography. Significant cardiovascular risk factors and symptoms compatible with unstable angina illustrate the common problem of a high probability of cardiac pathology in a patient with possible psychiatric symptoms. A modified SCID-interview complementing the coronary angiography results finally led to the definite diagnosis in this patient after symptoms had been present for over 20 years.

    Circulating endothelial cells (CECs) have been detected in association with endothelial injury and therefore represent proof of serious damage to the vascular tree. Our aim was to investigate, using the technique of immunomagnetic separation, whether the pathological events in unstable angina (UA) or acute myocardial infarction (AMI) could cause desquamation of endothelial cells in circulating blood compared with effort angina (EA) and noncoronary chest pain. A high CEC count was found in AMI (median, 7.5 cells/mL; interquartile range, 4.1 to 43.5, P chest pain as compared with controls (0; 0 to 0 cells/mL) and stable angina (0; 0 to 0 cells/mL). CEC levels in serial samples peaked at 15.5 (2.7 to 39) cells/mL 18 to 24 hours after AMI (P angina, confirming that these diseases have different etiopathogenic mechanisms.

    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.

    Bronchodilator responses to both nebulized albuterol (salbutamol) and ipratropium bromide and aerosol delivery to the tracheobronchial tree have been assessed in eight patients with chronic stable asthma (mean baseline FEV1, 50 percent; reversibility greater than 20 percent). Two commercially available nebulizer systems were used, namely, a Turret nebulizer operated at a compressed gas flow rate of 12 L/min (droplet MMD, 3.3 mu) and an Inspiron nebulizer driven at 6 L/min (MMD, 7.7 mu). Albuterol was given as doses of 250 micrograms, 250 micrograms, 500 micrograms, and 1,000 micrograms (cumulative dose, 2 mg) and ipratropium bromide as doses of 50 micrograms, 50 micrograms, 100 micrograms, and 200 micrograms (cumulative dose, 400 micrograms) at intervals of 35 minutes. For albuterol, bronchodilatation was significantly (p less than 0.05) greater at all dosage levels with the Turret. For ipratropium, bronchodilatation was similar for both nebulizers. Measurements of aerosol deposition using /sup 99m/Tc-labelled pentetic acid (diethylenetriamine pentaacetic acid; DTPA) showed that 9.1 +/- 1.1 percent and 2.7 +/- 0.2 percent of the dose reached the lungs during nebulization to dryness for Turret and Inspiron, respectively (p less than 0.01); distribution within the lungs was similar for the two aerosols. Selection of nebulizer apparatus can influence delivery of aerosol and subsequent bronchodilator response to albuterol in patients with chronic stable asthma but is less important for aerosol delivery of ipratropium bromide in these patients.

    Background Evidence suggests that systemic inflammation may play an important role in the progression and morbidity of chronic obstructive pulmonary disease. It remains controversial whether inhaled corticosteroid in combination with a long-acting β2-adrenoceptor agonist can attenuate systemic inflammation. We evaluated the effect of salmeterol/fluticasone propionate on circulating C-reactive protein level in stable chronic obstructive pulmonary disease patients.Methods An open-label clinical trial was conducted to recruit 122 outpatients with stable moderate-to-severe chronic obstructive pulmonary disease from department of respiratory medicine in two teaching hospitals between June 2007 and March 2008. Patients were randomized into two groups (1:1) to receive either the combination of 50 ug salmeterol and 500 ug fluticasone twice daily (n=61), or the combination of 206 ug albuterol and 36 ug ipratropium q.i.d (n=61) over 6 months. Circulating C-reactive protein concentrations were measured before randomization and during the follow-up. The efficacy of treatment was also assessed by spirometry, as well as health status and dyspnea score at baseline and after 6-month treatment.Results Baseline characteristics of two groups were similar. Compared with ipratropium/albuterol, the combination of salmeterol/fluticasone significantly reduced circulating level of C-reactive protein (-1.73 vs. 0.08 mg/L, respectively, P <0.05) after 6-month treatment. Forced expiratory volume in one second (FEV1) and health status also improved significantly in salmeterol/fluticasone group compared with ipratropium/albuterol. Salmeterol/fluticasone treatment subjects who had a decrease of circulating C-reactive protein level had a significant improvement in FEV1 and St George's Respiratory Questionnaire total scores compared with those who did not (185 vs. 83 ml and -5.71 vs. -1.79 units, respectively, both P<0.01).Conclusion Salmeterol/fluticasone treatment reduced circulating C

    The impact of preoperative stable angina pectoris on postoperative cardiovascular outcomes in patients with previous myocardial infarction (MI) who underwent major noncardiac surgery is not well studied. We studied patients with previous MI who underwent elective major noncardiac surgeries within the American College of Surgeons-National Surgical Quality Improvement Program (2005 to 2011). Primary outcome was occurrence of an adverse cardiac event (MI and/or cardiac arrest). Multivariable logistic regression models evaluated the impact of stable angina on outcomes. Of 1,568 patients (median age 70 years; 35% women) with previous MI who underwent major noncardiac surgery, 5.5% had postoperative MI and/or cardiac arrest. Patients with history of preoperative angina had significantly greater incidence of primary outcome compared to those without anginal symptoms (8.4% vs 5%, p = 0.035). In secondary outcomes, reintervention rates (22.5% vs 11%, p angina. In multivariable analyses, preoperative angina was a significant predictor for postoperative MI (odds ratio 2.49 [1.20 to 5.58]) and reintervention (odds ratio 2.40 [1.44 to 3.82]). In conclusion, our study indicates that preoperative angina is an independent predictor for adverse outcomes in patients with previous MI who underwent major noncardiac surgery, and cautions against overreliance on predictive tools, for example, the Revised Cardiac Risk Index, in these patients, which does not treat stable angina and previous MI as independent risk factors during risk prognostication.

    Background This meta-analysis evaluated the effect of noninvasive,positive pressure ventilation on severe,stable chronic obstructive pulmonary disease (COPD).Methods PUBMED,CNKI,Wanfang,EMBASE and the Cochrane trials databases were searched.Randomized controlled trials of patients with severe,stable COPD and receiving noninvasive positive pressure ventilation,compared with sham ventilation or no ventilation,were reviewed.The mortality,physiological and health related parameters were pooled to yield odds ratio (OR),weighted mean differences or standardized mean differences (SMD),with 95% confidence interval (C/).Results Eight parallel and three crossover randomized controlled trials met the inclusion criteria.Pooled analysis for parallel,randomized controlled trials showed noninvasive positive pressure ventilation:(1) Did not affect the 12-or 24-month mortality (OR 0.82,95% C/:0.48 to 1.41); (2) Improved the arterial carbon dioxide tension (SMD-0.88,95%C/:-1.43 to-0.34); (3) Did not improve forced expiratory volume in one second (SMD 0.20,95% C/:-0.06 to 0.46),maximal inspiratory pressure (SMD 0.01,95% C/:-0.28 to 0.29) or 6-minute walk distance (SMD 0.17,95% C/:-0.16 to 0.50); (4) Subgroup analysis showed noninvasive positive pressure ventilation improved the arterial carbon dioxide tension in hypercapnic patients.Pooled analysis for crossover randomized controlled trials did not show improvement in arterial blood gas or forced expiratory volume in one second with noninvasive positive pressure ventilation.Conclusions Noninvasive positive pressure ventilation improves the arterial carbon dioxide tension but does not improve the mortality,pulmonary function,or exercise tolerance and should be cautiously used in severe stable chronic obstructive pulmonary disease.

Métodos: estudio descriptivo realizado en el Instituto de Cardiología y Cirugía Cardiovascular de La Habana que incluyó 59 mujeres. Se les realizó lipidograma, se les midió función endotelial de la arteria braquial mediante ultrasonido, y estudio electrocardiográfico de 24 horas (Holter. Se aplicó un protocolo de estrés-reposo durante la gammagrafía. Las pacientes fueron divididas en dos grupos, acorde a la presencia (grupo I o ausencia (grupo II de defectos de perfusión miocárdica. Resultados: mostraron defectos de la perfusión 21 pacientes. El 57 % de las pacientes del grupo I exhibió más disfunción endotelial. Sólo doce pacientes mostraron defectos reversibles de la perfusión y en el 75 % de los casos se asoció a una reducción de la fracción de eyección ventricular izquierda postestrés mayor de un 5 % y a anormalidades regionales de la motilidad de la pared. Tres pacientes en el grupo I mostraron evidencia de isquemia comparado con cuatro en el grupo II. Conclusiones: la isquemia inducida por estrés se asocia a una reducción de la fracción de eyección ventricular izquierda postestrés y a una vasodilatación anormal dependiente del endotelio.

    Background The evidence for non-invasive positive pressure ventilation (NIPPV) used in patients with severe stable chronic obstructive pulmonary disease (COPD) is insufficient.The aim of the meta-analysis was to assess the treatment effects of long-term NIPPV on gas change,lung function,health-related quality of life (HRQL),survival and mortality in severe stable COPD patients.Methods Randomized controlled trials (RCTs) and crossover studies comparing the treatment effects of NIPPV with conventional therapy were identified from electronic databases and reference lists from January 1995 to August 2010.Two reviewers independently assessed study quality.Data were combined using Review Manager 5.0.Both pooled effects and 95% confidence intervals were calculated.Results Five RCTs and one randomized crossover study with a total of 383 severe stable COPD patients were included.NIPPV improved gas change significantly when using a higher inspiratory positive airway pressures.The weighted mean difference (WMD) for the partial pressure of carbon dioxide in artery (PaCO2) was -3.52 (-5.26,-1.77) mmHg and for the partial pressure of oxygen in artery (PaO2) 2.84 (0.23,5.44) mmHg.There were significant improvements in dyspnea and sleep quality,but gained no benefits on lung function.The standardized mean difference (SMD) for the forced expiratory volume in 1 second (FEV1)was 0.00 (0.29,0.29).And the benefits for exercise tolerance,mood,survival and mortality remained unclear.Conclusions Patients with severe stable COPD can gain some substantial treatment benefits when using NIPPV,especially improvements in gas change,dyspnea and sleep quality.Studies of high methodological quality with large population,especially those based on a higher inspiratory positive airway pressures are required to provide more evidences.

However, its effect on the sympathetic activation response to exercise is unknown.Aims: This study aimed to determine whether tiotropium use results in a sustained reduction in sympathetic activation during exercise.Methods: We conducted a 12-week, open-label (treatments: tiotropium 18 µg or oxitropium 0.2 mg × 3 mg, crossover study in 17 COPD patients. Treatment order was randomized across subjects. The subjects underwent a pulmonary function test and two modes of cardiopulmonary exercise (constant work rate and incremental exercise testing using a cycle ergometer, with measurement of arterial catecholamines after each treatment period.Results: Forced expiratory volume in 1 second and forced vital capacity were significantly larger in the tiotropium treatment group. In constant exercise testing, exercise endurance time was longer, with improvement in dyspnea during exercise and reduction in dynamic hyperinflation in the tiotropium treatment group. Similarly, in incremental exercise testing, exercise time, carbon dioxide production, and minute ventilation at peak exercise were significantly higher in the tiotropium treatment group. Plasma norepinephrine concentrations and dyspnea intensity were also lower during submaximal isotime exercise and throughout the incremental workload exercise in the tiotropium treatment group.Conclusion: Tiotropium suppressed the increase of sympathetic activation during exercise at the end of the 6-week treatment, as compared with the effect of oxipropium. This effect might be attributed to improvement in lung function and exercise capacity and reduction in exertional dyspnea

    Full Text Available Patienten mit instabiler Angina pectoris befinden sich grundsätzlich in einer lebensbedrohlichen Situation, die eine notfallmäßige sofortige Klinikeinweisung und Einleitung einer maximalen medikamentösen Therapie unter intensivmedizinischer Überwachung nötig macht. Trotz moderner diagnostischer Möglichkeiten ist der Nachweis einer tatsächlich instabilen Angina pectoris nicht immer einfach. In der Beurteilung des klinischen Schweregrades der Symptomatik und der daraus abzuleitenden Prognose einer instabilen Angina pectoris hat sich zuletzt hauptsächlich die Braunwald-Klassifikation durchgesetzt. Die leichteste Form der instabilen Angina pectoris ist die Klasse IA1, die schwerste Form die Klasse IIIC3. Wenn eine EKG-Registrierung während einer Episode von Angina pectoris eine akute ST- Streckenveränderung zeigt, muß mit einem höheren Schweregrad der Erkrankung gerechnet werden. Das EKG ist darüber hinaus ein wichtiger prognostischer Marker für den Langzeitverlauf der Patienten über 6 Monate bis 1 Jahr. Die Bestimmung der kardialen Troponine ist heute ein unerläßlicher Eckpfeiler der Diagnostik und Risikostratifizierung von Patienten mit instabiler Angina pectoris. Wie in großen Studien gezeigt wurde, haben Patienten mit instabiler Angina pectoris und positivem Troponin T eine schlechtere Prognose als jene ohne Anstieg. Ist das Troponin I bzw. das Troponin T 6 Stunden nach Schmerzbeginn negativ, haben die Patienten ein sehr geringes Risiko ( 1% für ein folgendes kardiales Ereignis in den nächsten 30 Tagen. Bei den Troponin-positiven Patienten liegt die ereignisfreie Überlebensrate hingegen bei lediglich etwa 80%. Das C-reaktive Protein ist kein Prädiktor für die Prognose, gerade wenn die kardialen Troponine normal sind. Deshalb sollte dieser Parameter nicht als alleinstehender prognostischer Marker zur Abklärung der instabilen Angina pectoris verwendet werden.

Recent biological studies indicated that lipocalins (LCNs might be involved in airway inflammation and innate immunity; however, results from available studies on the association of LCNs with COPD are not consistent. We carried out a multicenter prospective observational cohort study to investigate the differences in serum levels of LCN1 and LCN2 between subjects with COPD (n=58 and healthy controls (n=29. Several validated inflammatory markers, including C-reactive protein, tumor necrosis factor-a, interleukin-6, and interleukin-8, were measured. The correlation of LCN1 and LCN2 with clinical features such as smoking habits, lung function, symptoms, and disease category was also analyzed. When comparing with healthy controls, serum levels of LCN1 (66.35±20.26 ng/mL versus 41.16±24.19 ng/mL, P<0.001 and LCN2 (11.29±3.92 ng/mL versus 6.09±5.13 ng/mL, P<0.001 were both elevated in subjects with COPD after adjusting for age, sex, smoking habits, and inflammatory biomarkers. Smoking history and tobacco exposure, as quantified by pack-year, had no impact on systemic expressions of LCN1 and LCN2 in our study. Blood levels of LCN1 and LCN2

    The results are discussed of a retrospective study of 126 patients by whom an excess of the fusospirochaetal complex was found by direct microscopic examination of tonsillar material. These bacteria are not only found in unilateral ulcero-necrotic tonsillitis, but also in different other tonsillar and general diseases. Vincent's angina appears almost exclusively in young persons, aged from 16 to 25 years; in the adolescence (16-20 years) it forms about 40% of all cases of acute tonsillitis. The fusospirochaetal complex is also often found in chronic tonsillitis and even in morfologically normal tonsils, especially in patients with general diseases like rheumatic arthritis. In one third of the patients with infectious mononucleosis, the complex is present in the tonsillar lesions. The occurrence of Vincent's angina is double as high in women than in men. From our assessments we can conclude that the fusospirochaetal complex has a very low pathogenity, and that it only can grow in patients with a reduced local or general resistance, even without causing local lesions.

    Full Text Available Reninoma is a tumor of the renal juxtaglomerular cell apparatus that causes hypertension and hypokalemia because of hypersecretion of renin. We present a case of a 29-year-old female patient with reninoma and concomitant variant angina. The patient had uncontrolled hypertension and elevated plasma renin activity and aldosterone levels. Imaging studies revealed a mass in the left kidney, which was further confirmed as a renin-producing lesion via selective venous catheterization. During the evaluation, the patient had acute-onset chest pain that was diagnosed as variant angina after a provocation test. After partial nephrectomy, the plasma renin activity and plasma aldosterone levels decreased and blood pressure normalized. We report a case of reninoma with variant angina.

    Tolerance to both the bronchoprotective effect, and, to a lesser extent, the bronchodilator activity, occurs with all inhaled β2-agonists. Assumed the importance of this topic and the lack of a clinical evaluation specifically designed to assess the impact of chronic administration of indacaterol on the response to salbutamol, we sought to compare the effect of 4-week treatment with indacaterol 150 μg once-daily versus formoterol 12 μg twice-daily on the dose-response curve to inhaled salbutamol (total cumulative dose of 800 μg) in a non-double-blinded, crossover, randomised, and controlled pilot trial that enrolled 20 outpatients with moderate to severe COPD. At the end of 4-week treatments, there was not a statistically significant difference between the two trough FEV1 (p = 0.16), and both indacaterol and formoterol were able to produce a significant (p Salbutamol elicited an evident dose-dependent increase in FEV1 and this occurred also after regular treatment with indacaterol and formoterol with a further mean maximum increase of 0.10L (95% CI 0.05-0.14) and 0.05L (95% CI 0.02-0.08), respectively. The differences between indacaterol and formoterol in FEV1 increases after salbutamol were never statistically significant. The results of this study support the use of salbutamol as rescue medication for rapid relief of bronchospasm in patients suffering from COPD, even when they are under regular treatment with indacaterol.

    Full Text Available Introduction: COPD is a common preventable and treatable disease and a major cause of morbidity and mortality globally. ECG is a very simple, widely available and convenient bedside investigation that can be used to detect various cardiac abnormalities. Electrical activities of the heart are often influenced by COPD. ECG changes like P-wave abnormalities have to be carefully assessed before coming to an inference. Material and methods: The present study was an institutional based prospective study, conducted from July 2014 to June 2015. The study was designed to assess the various ECG abnormalities in stable COPD patients and to determine echocardiography findings in relation to ECG changes. Results: Among the P-wave abnormalities P-wave axis verticalisation (PWAV was observed in 59(76.6% patients. Twenty (26% patients showed negative P-wave in V1, significant-Ptf(P-terminal force was observed in 3(3.9% patients. P-mitrale was seen in 18(31.2%, and P-pulmonale in 16 (20.8% patients. Conclusion: Though not specific, ECG may reveal various functional and structural abnormalities of the heart in relation to COPD like PWAV. PWAV may be the most commonly seen P-wave abnormalities in COPD patients. Echocardiography findings suggest that presence of P-mitrale is not conclusive of left atrial overload in patients of COPD. Echocardiography should be done routinely in all COPD patients to confirm ECG findings and to diagnose pulmonary hypertension, cor-pulmonale and other subclinical cardiovascular co-morbidities like left ventricular diastolic dysfunction.

    Objective To determine the prevalence of sleep-disordered breathing in patients with stable, optimally treated chronic congestive heart failure and the effect of short-term oral theophylline therapy on periodic breathing in these patients.Methods Patients with stable, optimally treated chronic congestive heart failure were monitored by polysomnography during nocturnal sleep. The effects of theophylline therapy on periodic breathing associated with stable heart failure were observed before and after treatment.Results Patients were divided into two groups. GroupⅠ(n=21) consisted of individuals with 15 episodes of apnea and hypopnea [as determined by the apnea-hypopnea index (AHI)] per hour or less; Group Ⅱ (n=15, 41.7%) individuals had an index of more than 15 episodes per hour. In group Ⅱ, the AHI varied from 16.8 to 78.8 (42.6±15.5) in which the obstructive AHI was 11.1±8.4 and the central AHI was 31.5±9.6. Group Ⅱ had significantly more arousals (36.8±21.3 compared with 19.4±11.2 in group Ⅰ) that were directly attributable to episodes of apnea and hypopnea, lower arterial oxyhemoglobin saturation (76.7%±4.6% compared with 86.5%±2.8%) and lower left ventricular ejection fraction (24.2%±8.8% compared with 31.5%±10.6%). Thirteen patients with compensated heart failure and periodic breathing received theophylline orally (at an average dose of 4.3 mg/kg) for five to seven days. After treatment, the mean plasma theophylline concentration was (11.3±2.5) μg/ml. Theophylline therapy resulted in significant decreases in the number of AHI (20.8±13.2 vs. 42.6±15.5; P<0.001) and the number of episodes of central apnea-hypopnea per hour (10.1±7.6 vs. 31.5±9.6; P<0.001). Furthermore, the percentage of total sleep time during which arterial oxyhemoglobin saturation (SaO2) was less than 90 percent (8.8%±8.6% vs. 23.4%±24.1%; P<0.05) and the arousals per hour (18.7±21.2 vs. 36.8±21.3; P<0.05) were also lower. There were no significant differences in the

    Acute coronary syndromes include ST-elevation and non-ST elevation myocardial infarction, and unstable angina pectoris. These are characterised by the acute onset of chest pain. For the diagnostic work up in the acute phase, ECG and the assessment of cardiac markers play a central role. For patients with ST-elevation, primary interventional therapy is the first choice. For patients with an acute coronary syndrome without ST-elevation, a risk adapted therapeutic strategy should be chosen. High risk patients (elevated troponins, clinical, rhythmological and hemodynamic instability, ST-depression and diabetes mellitus) should be treated by an early invasive approach with angiography performed within 48-72 h. Low risk patients should be treated conservatively. For all patients who are treated interventionally, the administration of an aggressive antiaggregatory therapy including aspirin, clopidogrel, glycoprotein IIb/IIIa inhibitors and heparin is indicated in the acute phase. In the chronic phase, the treatment of cardiovascular risk factors is of paramount importance.

    Some patients of ischemic heart disease have low uptake in {sup 123}I-labeled beta methyl-iodophenyl pentadecanoic acid (BMIPP) SPECT in spite of normal uptake in thallium-201 (Tl) SPECT. To investigate their clinical significance, we performed both Tl and BMIPP myocardial SPECT in 26 cases with stable angina (n=16) and unstable angina (n=10), and compared with clinical backgrounds electrocardiogram (ECG) and left ventriculography (LVG). In 11 patients of them, the uptake of BMIPP was moderately reduced. We divided 26 cases into two groups according to uptake of BMIPP (normal/reduced). The two groups had no differences in length of angina attack and duration of disease, but they had a significant difference in the abnormality of either ECG or LVG. Three to six months after PTCA, we examined LVG in 18 cases, 12 of 16 cases with the abnormality of LVG showed the improvement of wall motion. We concluded the reduced uptake of BMIPP with normal uptake of Tl was related to more severe ischemia in cases with unstable angina. (author)

    Background The relationship between the 6-minute walk test (6MWT) and pulmonary function test in stable chronic obstructive pulmonary disease (COPD) remains unclear.We evaluate the correlation of 6MWT and spirometric parameters in stable COPD with different severities.6MWT data assessed included three variables:the 6-minute walk distance (6MWD),6-minute walk work (6MWORK),and pulse oxygen desaturation rate (SPO2%).Methods 6MWT and pulmonary function test were assessed for 150 stable COPD patients with different severities.Means and standard deviations were calculated for the variables of interest.Analysis of variance was performed to compare means.Correlation coefficients were calculated for 6MWT data with the spirometric parameters and dyspnea Borg scale.Multiple stepwise regression analysis was used to screen pulmonary function-related predictors of 6MWT data.Results The three variables of 6MWT all varied as the severities of the disease.The 6MWD and 6MWORK both correlated with some spirometric parameters (positive or negative correlation; the absolute value of r ranging from 0.34 to 0.67; P<0.05) in severe and very severe patients,and the SPO2% correlated with the dyspnea Borg scale in four severities (r=-0.33,-0.34,-0.39,-0.53 respectively; P <0.05).The 6MWD was correlated with the 6MWORK in four severities (r=0.56,0.57,0.72,0.81 respectively,P <0.05),and neither of them correlated with the SPO2%.The percent of predicted forced expiratory volume in 1 second (FEV1% predicted) and residual volume to total lung capacity ratio (RV/TLC) were predictors of the 6MWD,and the maximum voluntary ventilation (MW) was the predictor of the 6MWORK.Conclusions 6MWT correlated with the spirometric parameters in severe and very severe COPD patients.6MWT may be used to monitor changes of pulmonary function in these patients.

    Full Text Available Abstract Background Chronic obstructive pulmonary disease (COPD is the 4th leading cause of mortality worldwide. Long-acting bronchodilators are considered first line therapies for patients with COPD but their effects on mortality are not well known. We performed a comprehensive systematic review and meta-analysis to evaluate the effects of long-acting bronchodilators on total mortality in stable COPD. Methods Using MEDLINE, EMBASE and Cochrane Systematic Review databases, we identified high quality randomized controlled trials of tiotropium, formoterol, salmeterol, formoterol/budesonide or salmeterol/fluticasone in COPD that had a follow-up of 6 months or longer and reported on total mortality. Two reviewers independently abstracted data from the original trials and disagreements were resolved by iteration and consensus. Results Twenty-seven trials that included 30,495 patients were included in the review. Relative risk (RR for total mortality was calculated for each of the study and pooled together using a random-effects model. The combination of inhaled corticosteroid (ICS and long-acting beta-2 agonist (LABA therapy was associated with reduced total mortality compared with placebo (RR, 0.80; p = 0.005. Neither tiotropium (RR, 1.08; p = 0.61 nor LABA by itself (RR, 0.90; p = 0.21 was associated with mortality. Conclusions A combination of ICS and LABA reduced mortality by approximately 20%. Neither tiotropium nor LABA by itself modifies all-cause mortality in COPD.

    Many changes associated with bariatric surgery have the potential to affect warfarin dosing; yet current literature includes little data describing this phenomenon. Investigating this relationship may allow for determination of post-bariatric surgery warfarin dosing using stable pre-operative dosing levels. A retrospective chart review was completed for 10 patients stabilized on chronic warfarin therapy who underwent bariatric surgery. Data collection consisted of the following: warfarin requirement in mg/week, time in target range (TTR), creatinine, liver function, diarrhoea, medication changes, diet, and signs of bleeding and/or thrombosis. Three study patients underwent laparoscopic adjustable gastric banding procedures and seven patients underwent Roux-en-Y gastric bypass. The average (standard deviation) weekly warfarin dose required in the immediate post-operative interval was 64% (25%) of baseline dosing, corresponding to a TTR of 48%. At 6 months, patients required 85% (19%) of baseline weekly dosing, with TTR of 53.4%. At 1 year, dosing was 90% (16%) of baseline with TTR of 63.5%. Patients underwent medication changes as well as transient bouts of diarrhoea. Two patients suffered unspecified haemorrhages of the gastrointestinal tract (international normalized ratio [INR] = 2.3 and 9.8). This patient set demonstrated an initial drop in warfarin requirement, followed by escalating dosing trends that became more predictable as patients were farther out from procedure.

    Full Text Available The effects of low concentration of sevoflurane on right ventricular (RV function and intracellular calcium in the setting of pulmonary arterial hypertension (PAH have not been investigated clearly. We aim to study these effects and associated signaling pathways in rats with PAH.Hemodynamics were assessed with or without sevoflurane inhalation in established PAH rats. We analysis the classic RV function parameters and RV-PA coupling efficiency using steady-state PV loop recordings. The protein levels of SERCA2, PLB and p-PLB expression was analyzed by western blot to assess their relevance in PAH.Rats with PAH presented with RV hypertrophy and increased pulmonary arterial pressure. The values of Ea, R/L ratio, ESP, SW, PRSW, +dP/dtmax and the slope of the dP/dtmax-EDV relationship increased significantly in PAH rats (P<0.05. Sevoflurane induced a concentration-dependent decrease of systemic and pulmonary blood pressure, HR, RV contractility, and increased the R/L ratio in both groups. Sevoflurane reduced the expression of SERCA2 and increased the expression of PLB in both groups. Interestingly, sevoflurane only reduced the p-PLB/PLB ratio in PAH rats, not in normal rats.Rats with chronic, stable pulmonary hypertension tolerate low concentrations of sevoflurane inhalation as well as normal rats do. It may be related to the modulation of the SERCA2-PLB signaling pathway.

    In this study, we investigated the role of the -174G>C polymorphism of interleukin-6 (IL-6) as a predisposing factor to angina pectoris. Patients were separated into 2 groups: angina (N = 72) and nonangina (N = 71). There were no statistical differences between groups for all cardiovascular risk factors evaluated. The GG genotype frequency was 18% lower in the angina than in the non-angina group, whereas GC + CC was 18% higher in the angina group (P = .036). The frequency of G allele was 11% lower in the angina than in the nonangina group and C allele was 11% higher in the angina group (P = .043). Patients carrying the C allele showed a 2-fold increased risk for angina pectoris (P = .036). Our study demonstrates a high incidence of the -174G>C polymorphism of the IL-6 gene in patients with angina pectoris compared with those carrying the G allele, reinforcing the contribution of genetic factors to the symptoms of angina pectoris.

    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.

Both the twice-daily long-acting ß2-adrenoceptor agonists (LABAs salmeterol and formoterol and the once-daily LABA indacaterol are indicated for use in COPD. This review examines current evidence for the safety of LABAs in COPD, focusing on their effect on exacerbations and deaths.Methods: We searched PubMed for placebo-controlled studies evaluating long-term (≥24 weeks use of formoterol, salmeterol, or indacaterol in patients with stable COPD, published between January 1990 and September 2012. We summarized data relating to exacerbations and adverse events, particularly events related to COPD.Results: From 20 studies examined (8774 LABA-treated patients, there was no evidence of an association between LABA treatment and increased exacerbations, COPD-related adverse events, or deaths. Where analyzed as an efficacy outcome, LABA treatment was generally associated with significant or numerical reductions in COPD exacerbations compared with placebo. Incidences of COPD-related adverse events were similar for active and placebo treatments. The incidence of adverse events typically associated with the ß2-agonist drug class such as skeletal muscle tremors and palpitations was low (often <1% of patients, and there were no reports of increased incidence of cardiac arrhythmias. The systemic effects of ß2-adrenoceptor stimulation, such as high glucose and potassium levels, were considered minor.Conclusion: Current evidence from clinical studies of the

    Biovariability, reference change values (RCV), and index of individuality (IOI) have not been previously described for NT-proANP or GDF15. Also, the relation of changes of these markers to other clinical variables or biomarkers is unknown. In 41 patients with stable chronic systolic dysfunction, NT-proANP and GDF15 were measured alongside with clinical variables/markers comprising NT-proBNP, hsTnT, and hsCRP at four sampling intervals (2 weeks, 1-, 2-, 3-month intervals). At 2 weeks, 1-, 2-, and 3-month-follow-up, individual NT-proANP variations were 27.1, 22.5, 28.9, 15.6%, respectively, corresponding to RCVs of 53.2, 62.4, 80.2, and 43.2%, respectively. For GDF15, the respective individual variations were 6.8, 4.1, 5.5, 6.8%, corresponding to RCVs of 18.8, 11.5, 15.3 and 18.8%. Neither changes of NT-proANP or GDF15 correlated with changes in any of the clinical variables or biomarkers examined except for GDF15 with renal function. Baseline hormonal levels and clinical variables did not consistently influence the extent of change. The IOI was 0.19-0.35 according to interval for NT-proANP and 0.06-0.09 for GDF 15. In patients with CHF preselected for clinical stability changes of NT-proANP at intermediate follow-up do not correlate with changes in other variables; changes of GDF15 inversely correlate with renal function. The extent of change in both markers is not related to baseline hormonal levels or other baseline variables. RCVs are high for NT-proANP and low for GDF15, while inter-individual variation is high in GDF15 and intermediate in NT-proANP.

    Acupuncture therapy on PC 6 (Neiguan) has a therapeutic effect on cardiac and chest ailments including angina pectoris. Additional beneficial acupuncture points are PC 4 (Ximen), HT 7 (Shenmen point), PC 7 (Daling point), PC 5 (Jianshi point), PC 3 (Quze point), CV 17 (Danzhong point), CV 6 (Qihai point), BL 15 (Xinshu point), L 20 (Pishu point), BL 17 (Geshu point), BL23 (Shenshu point), BL18 (Ganshu point), HT 5 (Tongli point), and ST36 (Zusanli point). Acupuncture not only quickly relieve the symptoms of acute angina pectoris, but also improve nitroglycerine's therapeutic effects. Therefore, it is an efficient simple therapeutic method used for emergency and for regular angina treatment. Review of studies on acupuncture therapy has shown effectiveness were between 80% to 96.2% that are almost as effective as conventional drug regimen. When compared with conventional medical treatment, the acupuncture therapy shows the obvious advantage of lacking, adverse side effects commonly associated with the Western anti-anginal drugs such as 1) Nitroglycerine (headache--63% with nitroglycerine patch and 50% with spray; syncope--4%; and dizziness--8% with patch; hypotension--4% with patch; and increased angina 2% with patch). 2) Isosorbide mononitrate (dizziness--3 to 5%; nausea/vomiting--2 to 4% and other reactions including hypotension, and syncope even with small doses). 3) Propranolol (bradycardia, chest pain, hypotension, worsening of AV conduction disturbance, Raynaud's syndrome, mental depression, hyperglycemia, etc.). Many conventional anti-anginal medications cause inter-drug reactions with other medications the patients taking for other diseases. Whereas, acupuncture therapy does not pose such an interference with patient's medications. Nevertheless, surgery is still the treatment of choice when acupuncture or conventional drug therapy fails. Combination of conventional drug therapy and acupuncture would considerably decrease the frequency and the required dosage

    Angina pectoris is the consequence of an inequality between the demand and supply of blood to the heart. Angina manifests itself as chest pain or discomfort and is a common complaint of patients in the hospital and in the clinic. There are, in fact, roughly half a million new cases of angina per year. Chest pain, while having many etiologies, is generally considered to be most lethal when related to a cardiac cause. In this review, the authors outline the current medical and surgical therapies that are used in the management of angina. Highlights of the various clinical trials that have assisted in the investigation of these therapies are summarized also. Then, the authors provide a focused review of the novel therapy options for angina that are currently being explored. From new medical treatments to revised surgical techniques to the discovery of stem cell therapy, many innovative options are being investigated for the treatment of angina.

    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.

    Full Text Available Bacground/Aim. Chronic heart failure (CHF is highly prevalent and constitutes an important public health problem around the world. In spite of a large number of pharmacological agents that successfully decrease mortality in CHF, the effects on exercise tolerance and quality of life are modest. Renal dysfunction is extremely common in patients with CHF and it is strongly related not only to increased mortality and morbidity but to a significant decrease in exercise tolerance, as well. The aim of our study was to investigate the prevalence and influence of the renal dysfunction on functional capacity in the elderly CHF patients. Methods. We included 127 patients aged over 65 years in a stable phase of CHF. The diagnosis of heart failure was based on the latest diagnostic principles of the European Society of Cardiology. The estimated glomerular filtration rate (eGRF was determined by the abbreviated Modification of Diet in Renal Disease (MDRD2 formula, and patients were categorized using the Kidney Disease Outcomes Quality Initiative (K/DOQI classification system. Functional capacity was determined by the 6 minute walking test (6MWT. Results. Among 127 patients, 90 were men. The average age was 72.5 ± 4.99 years and left ventricular ejection fraction (LVEF was 40.22 ± 9.89%. The average duration of CHF was 3.79 ± 4.84 years. Ninty three (73.2% patients were in New York Heart Association (NYHA class II and 34 (26.8% in NYHA class III. Normal renal function (eGFR ≥ 90 mL/min had 8.9% of participants, 57.8% had eGFR between 60-89 mL/min (stage 2 or mild reduction in GFR according to K/DOQI classification, 32.2% had eGFR between 30-59 mL/min (stage 3 or moderate reduction in GFR and 1.1% had eGFR between 15-29 mL/min (stage 4 or severe reduction in GFR. We found statistically significant correlation between eGFR and 6 minute walking distance (6MWD (r = 0.390, p < 0.001, LVEF (r = 0.268, p < 0.05, NYHA class (ς = -0.269, p < 0.05 and age (r = - 0

    Although metallic coronary stents significantly reduce angina pectoris compared with optimal medical therapy, angina after percutaneous coronary intervention (PCI) remains frequent. We, therefore, sought to compare the incidence of any angina during the 1 year after PCI among the spectrum of commercially available metallic stents. Metallic stent type was classified as bare metal stent, Cypher, Taxus Express, Xience V, Promus Element, and Resolute. The primary end point was patient-reported angina within 1 year of PCI. Multivariable logistic regression was performed to assess the independent association of stent type with any angina at 1 year. Overall, 8,804 patients were queried in regard to angina symptoms; 32.3% experienced angina at some point in the first year after PCI. Major adverse cardiovascular events, a composite of all-cause mortality, target vessel revascularization, and Q-wave myocardial infarction, increased with angina severity: 6.8% for patients without angina, 10.0% for patients with class 1 or 2 angina, and 19.7% for patients with class 3 or 4 angina (p angina at 1 year after PCI. Baseline Canadian Cardiovascular Society class 3 or 4 angina, history of coronary artery bypass grafting, and history of PCI were associated with a higher likelihood of angina at 1 year; increasing age, male gender, presentation with acute coronary syndrome, and higher stented length were associated with less angina. In conclusion, metallic stent type is not associated with the occurrence of angina at up to 1 year after PCI.

    Stable chronic coronary artery disease (SCAD) encompasses several groups of patients including those with stable angina pectoris or other symptoms thought to be linked to CAD as well as patients with known prior acute coronary syndrome or prior coronary interventions, who have become asymptomatic with treatment and need regular follow-up. Patients with SCAD have an elevated risk for subsequent ischemic events and significantly benefit not only from lipid-lowering therapy with statins but also in particular from long-term antithrombotic treatment. These patients therefore need lifelong antithrombotic treatment with 100 mg acetylsalicylic acid (ASA) daily whereby clopidogrel 75 mg daily is indicated as an alternative in cases of aspirin intolerance. As chronic CAD may present with very different developmental phases spanning from chronic stable phases to acute coronary syndromes, antithrombotic treatment in SCAD patients needs continuous evaluation and adaptation. In addition, new concomitant diseases, such as atrial fibrillation may necessitate further adaptation of antithrombotic therapy. The current overview focuses on the description of the long-term antithrombotic treatment of SCAD as well as on the need for adaptation in the setting of elective percutaneous coronary interventions (PCI).

    Full Text Available Angina bullosa hemorrhagica is a rare and benign disorder, usually localized in the subepithelial layer of the oral, pharyngeal and esophageal mucosa. The lesions are characterized by their sudden onset. They appear as a painless, tense, dark red and blood-filled blister in the mouth that rapidly expand and rupture spontaneously in 24-48 hours. The underlying etiopathology remains ill defined, although it may be a multifactorial phenomenon including diabetes, and steroid inhalers. The condition is not attributable to blood dyscrasias, nor other vesicular-bullous disorders. In this study, eleven patients with such blisters are described. Physical examination of the patients revealed a single blister with hemorrhagic content localized in the oral mucosa. Biopsy of the lesions showed sub epithelial blisters with a mild infiltrate. In general practice, dermatologists could face a blood-filled bullous lesion of the oral mucosa. Recognition is, therefore, of great importance for dermatologists.

    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)

Chronic kidney disease (eGFR<60 mL/min/1.73 m2 was seen in 22.1% of the cohort (6.9% with eGFR<45 mL/min/1.73 m2; lower eGFR was associated with increasing age, female sex, cardiovascular risk factors, overt vascular disease, other comorbidities and higher systolic but lower diastolic blood pressure. High use of secondary prevention was seen across all CKD stages (overall 93.4% lipid-lowering drugs, 95.3% antiplatelets, 75.9% beta-blockers. The proportion of patients taking statins was lower in patients with CKD. Antiplatelet use was significantly lower in patients with CKD whereas oral anticoagulant use was higher. Angiotensin-converting enzyme inhibitor use was lower (52.0% overall and inversely related to declining eGFR, whereas angiotensin-receptor blockers were more frequently prescribed in patients with reduced eGFR.Chronic kidney disease is common in patients with stable coronary artery disease and is associated with comorbidities. Whilst use of individual evidence-based medications for secondary prevention was high across all CKD categories, there remains an opportunity to improve the proportion who take all three classes of preventive therapies. Angiotensin-converting enzyme inhibitors were used less frequently

However, its therapeutic effect remains undefined due to the unclear nature of diaphragmatic mobilization during IMT. Diaphragmatic mobilization, represented by transdiaphragmatic pressure (Pdi, and neural respiratory drive, expressed as the corrected root mean square (RMS of the diaphragmatic electromyogram (EMGdi, both provide vital information to select the proper IMT device and loads in COPD, therefore contributing to the curative effect of IMT. Pdi and RMS of EMGdi (RMSdi% were measured and compared during inspiratory resistive training and threshold load training in stable patients with COPD.Patients and methods: Pdi and neural respiratory drive were measured continuously during inspiratory resistive training and threshold load training in 12 stable patients with COPD (forced expiratory volume in 1 s ± SD was 26.1%±10.2% predicted.Results: Pdi was significantly higher during high-intensity threshold load training (91.46±17.24 cmH2O than during inspiratory resistive training (27.24±6.13 cmH2O in stable patients with COPD, with P<0.01 for each. Significant difference was also found in RMSdi% between high-intensity threshold load training and inspiratory resistive training (69.98%±16.78% vs 17.26%±14.65%, P<0.01.Conclusion: We concluded that threshold load training shows greater mobilization of Pdi and neural respiratory drive than inspiratory resistive training in stable patients with COPD.

    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

    This study was undertaken to assess the diagnostic value of resting {sup 123}I-BMIPP scintigraphy in patients with effort angina pectoris. One hundred and four patients underwent scintigraphic and angiographic examinations. The subsets of the patients were stable effort angina pectoris (stable type) in 27 cases, new onset of effort angina pectoris (new onset type) in 21 cases, and worsening effort angina pectoris (worsening type) in 35 cases. The remaining 21 cases were subjects without evidences of coronary artery disease (non-CAD). {sup 123}I-BMIPP was injected under resting and pain free condition, then data for single photon emission tomography (SPECT) were acquired. The positive regional {sup 123}I-BMIPP defects in three coronary territories were visually judged on the tomographic images. The overall sensitivity to diagnose the patients was 62.6% (52/83) and the overall specificity to exclude non-CAD subjects was 95.2% (20/21). The detection rate in each subset of the disease was 48.1% (13/27) in stable type, 47.6% (10/21) in new onset type and 77.1% (27/35) in worsening type (p<0.05 versus two other types). For detection of stenosed vessels, the overall sensitivity was 41.4% (56/148) and the overall specificity was 93.8% (152/164). The rate of detection of stenosed vessels was 31.7% (13/41) in stable type, 31.4% (11/35) in new onset type, and 55.6% (40/72) in worsening type (p<0.05 versus two other types). Vessels with 75% stenosis were more sensitively detected in the worsening type (33.3%; 4/12) compared to the remaining two types (8.3%; 1/12) even though the difference was not significant. The resting {sup 123}I-BMIPP scintigraphy was therefore valuable in diagnosing patients with effort angina pectoris and involved coronary arteries especially in the subset of patients with worsening type.

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

    The purpose of this study was to evaluate the inhibitory effect of procaterol (procaterol hydrochloride, CAS 62929-91-3) on exercise dynamic lung hyperinflation during the 6-min walk test (6MWT) in stable chronic obstructive disease (COPD) patients. Fourteen patients with stable COPD who were referred to our clinic between July 2008 and October 2009 were evaluated in this study. After the inhalation of procaterol, values for the lung function test, including vital capacity, inspiratory capacity, forced vital capacity, and FEV1/FEV1pred showed a significant improvement. Compared to the baseline assessment, the 6-min walk distance increased by a mean of 20.5 m when measured after inhalation of procaterol (512.4 +/- 90.7 m vs. 532.9 +/- 79.8 m, p lung hyperinflation, suggesting the important role of the beta2-receptor agonist procaterol in the treatment of COPD. It is therefore likely that most patients with COPD may derive considerable benefit from bronchodilator therapy with procaterol.

    Objective: To evaluate the effect of Yufeining (愈肺宁), a traditional Chinese medicine, on induced sputum interleukin-8 (IL-8) in patients with chronic obstructive pulmonary disease (COPD) at the stable phase. Methods: Thirty-six patients with COPD were divided into trial group (18 cases) and control group (18 cases) randomly. The trial group was treated with Yufeining pills taken orally for half a year; thecontrol group was not given any medicine. Routine lung function was recorded before and after treatment. Total cell count (TCC), differential cell counts (DCCs) and IL-8 in induced sputum were determined at the baseline and 6 months later. Results: The indices of lung function improved significantly after 6 months' treatment in trial group (P<0.05); TCC and absolute neutrophil count decreased significantly compared with baseline in the trial group (P<0.05); Sputum IL-8 concentration dropped significantly after 6 months' treatment, from a mean of 5. 216±2.914 μg/L to 4. 222± 2.140 μg/L (P<0.05). There were insignificant changes in the parameters in the control group between baseline and 6 months later. Conclusion: Yufeining could improve lung function, decrease sputum TCC, absolute neutrophil count and IL-8 concentration, and relieve airway inflammation in patients with COPD in the stable phase.

  3. Diabetes induces stable intrinsic changes to myeloid cells that contribute to chronic inflammation during wound healing in mice

    Acute inflammation in response to injury is a tightly regulated process by which subsets of leukocytes are recruited to the injured tissue and undergo behavioural changes that are essential for effective tissue repair and regeneration. The diabetic wound environment is characterised by excessive and prolonged inflammation that is linked to poor progression of healing and, in humans, the development of diabetic foot ulcers. However, the underlying mechanisms contributing to excessive inflammation remain poorly understood. Here we show in a murine model that the diabetic environment induces stable intrinsic changes in haematopoietic cells. These changes lead to a hyper-responsive phenotype to both pro-inflammatory and anti-inflammatory stimuli, producing extreme M1 and M2 polarised cells. During early wound healing, myeloid cells in diabetic mice show hyperpolarisation towards both M1 and M2 phenotypes, whereas, at late stages of healing, when non-diabetic macrophages have transitioned to an M2 phenotype, diabetic wound macrophages continue to display an M1 phenotype. Intriguingly, we show that this population predominantly consists of Gr-1+ CD11b+ CD14+ cells that have been previously reported as ‘inflammatory macrophages’ recruited to injured tissue in the early stages of wound healing. Finally, we show that this phenomenon is directly relevant to human diabetic ulcers, for which M2 polarisation predicts healing outcome. Thus, treatments focused at targeting this inflammatory cell subset could prove beneficial for pathological tissue repair.

    In traditional Chinese medicine (TCM), the Yiqigubiao pill is commonly used to enhance physical fitness. The current clinical trial was designed to evaluate the efficacy and safety of the Yiqigubiao pill as an adjuvant therapy for patients with stable chronic obstructive pulmonary disease (COPD). The current trial was a randomized, double-blind, placebo-controlled superiority trial. The participants were recruited from outpatients at the Traditional Chinese Medicine Hospital affiliated with Xinjiang Medical University (Ürümqi, China) between February and September 2012. All participants were patients with stable COPD that were randomized to the Yiqigubiao pill (YQGB; n=84) or placebo (Pb; n=87) groups. The occurrences of acute exacerbation (AE) of COPD during the trial were recorded. Lung function value assessments, scoring of life quality and exercise endurance, arterial blood gas analysis and serum inflammatory cytokines level determination were performed prior to and throughout the study. A total of 139 participants completed the intervention and 132 participants completed the study. The interval between the initial intervention and the first AECOPD was greater in the YQGB group compared with the Pb group (P<0.01). The incidence rate of AECOPD was lower in the YQGB group than in the Pb group (P<0.01). Subsequent to the intervention or at the end of the study, the 6-min walking distance difference was longer in the YQGB group compared with the Pb group (P<0.01). The scores reflecting life quality decline became lower in the YQGB group (P<0.01). The serum levels of proinflammatory factors were downregulated to a greater extent in the YQGB group compared with the Pb group. Thus, the Yiqigubiao pill is an efficient and safe adjuvant therapy for the treatment of stable patients with COPD. PMID:27698749

    Angina bullosa haemorrhagica is a benign phenomenon that is characterized by the sudden appearance of a blood blister on the oral mucosa in the absence of an identifiable cause or systemic disorder; local trauma has been suggested to be the most likely contributory factor. No treatment is required. Angina bullosa haemorrhagica affects mainly middle-aged and elderly people. There is no strong predilection for either men or women. In this article nine patients with such blisters are described. Blood blisters apparently are more common than has been suggested in the literature.

    Full Text Available Patients with deep neck infections present challenging airways for an anesthesiologist . Ludwig’s angina is potentially lethal, rapidly spreading cellulitis involving the floor of the mouth and neck. Without aggressive management it often results in life th reatening upper airway obstruction. Securing the airway remains the top priority in treatment of Ludwig’s angina. Although awake fibreoptic intubation remains the ideal method for securing the airway, but it is not available in every set up, so all feasibl e options of securing the airway should be prepared. We present a case successfully managed at our hospital with a brief review of airway management options.

A terapêutica utilizada baseia-se sobretudo no uso de corticosteroides e imunossupressores. É relatado o caso de uma paciente, 33 anos, com mal-estar, febre, mialgia, cefaleia intensa, pulsátil, holocraniana, resistente a analgésicos, hipertensão arterial sistêmica de difícil controle, claudicação no membro inferior direito e dor abdominal de forte intensidade, a qual piorava após a alimentação. A angiotomografia revelou aneurisma da aorta ascendente, estenose da artéria ilíaca comum direita, estenose das artérias renais e estenose da artéria mesentérica superior, fato que embasou o diagnóstico de angina mesentérica e a conduta intervencionista através da angioplastia transluminal percutânea múltipla com a colocação de stents.Takayasu's arteritis (TA is an idiopathic chronic inflammatory disease of the connective tissue that affects mainly the aorta and its branches. 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.

    Cardiac chest pain is accompanied by oxidative stress, which generates alkanes and other volatile organic compounds (VOCs). These VOCs are excreted in the breath and could potentially provide a rational diagnostic marker of disease. The breath methylated alkane contour (BMAC), a 3-dimensional surface plot of C4-C20 alkanes and monomethylated alkanes, provides a comprehensive set of markers of oxidative stress. In this pilot study, we compared BMACs in patients with unstable angina pectoris and in healthy volunteers. Breath VOCs were analyzed in 30 patients with unstable angina confirmed by coronary angiography and in 38 age-matched healthy volunteers with no known history of heart disease (mean age +/- SD, 62.7 +/- 12.3 years and 62.5 +/- 10.0, not significant). BMACs in both groups were compared to identify the combination of VOCs that provided the best discrimination between the 2 groups. Forward stepwise entry discriminant analysis selected 8 VOCs to construct a predictive model that correctly classified unstable angina patients with sensitivity of 90% (27 of 30) and specificity of 73.7% (28 of 38). On cross-validation, sensitivity was 83.3% (25 of 30) and specificity was 71.1% (27 of 38). We conclude that the breath test distinguished between patients with unstable angina and healthy control subjects.

    Ischemic heart disease (IHD) is the leading cause of death among women in Western countries, and it is associated with higher morbidity and mortality than in men. Nevertheless, IHD in women remains underdiagnosed and undertreated, and the misperception that females are "protected" against cardiovascular disease leads to underestimation of their cardiovascular risk; instead, women with chest pain have a high risk of cardiovascular events. Women suffering from angina pectoris tend to have different characteristics compared to men, with a high prevalence of non-significant coronary artery disease. Angina in women is more commonly microvascular in origin than in men, and therefore standard diagnostic algorithms may be suboptimal for women. This different pathophysiology impacts clinical management of IHD in women. While response to medical therapy may differ in women, they are scarcely represented in clinical trials. Therefore, solid data in terms of gender efficacy of antianginal drugs are lacking, and particularly when angina is microvascular in origin women often continue to be symptomatic despite maximal therapy with classical antianginal drugs. Recently, new molecules have shown promising results in women. In conclusion, women with angina are a group of patients in whom it seems appropriate to concentrate efforts aimed at reducing morbidity and improving quality of life.

    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.

    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.).

It results from chronic inflammation and causes irreversible airway damage. Levels of different serum cytokines could be surrogate biomarkers for inflammation and lung function in COPD. We aimed to determine the serum levels of different biomarkers in COPD patients, the association between cytokine levels and various prognostic parameters, and the key pathways/networks involved in stable COPD. In this study, serum levels of 48 cytokines were examined by multiplex assays in 30 subjects (control, n=9; COPD, n=21. Relationships between serum biomarkers and forced expiratory volume in 1 second, peak oxygen uptake, body mass index, dyspnea score, and smoking were assessed. Enrichment pathways and networks analyses were implemented, using a list of cytokines showing differential expression between healthy controls and patients with COPD by Cytoscape and GeneGo Metacore™ softwares (Thomson-Reuters Corporation, New York, NY, USA. Concentrations of cutaneous T-cell attracting chemokine, eotaxin, hepatocyte growth factor, interleukin 6 (IL-6, IL-16, and stem cell factor are significantly higher in COPD patients compared with in control patients. Notably, this study identifies stem cell factor as a biomarker for COPD. Multiple regression analysis predicts that cutaneous T

    There is conflicting evidence whether or not early postinfarction angina implies an unfavorable prognosis. This prospective study assessed the significance and natural history of early angina in a broad population of patients conservatively managed after acute myocardial infarction (AMI) and enrolled in the third Gruppo Italiano per lo Studio della Sopravvivenza nel Infarto Miocardico (GISSI-3) trial. Out of 2,363 consecutive patients (age 63 +/- 11; first AMI in 86%; thrombolysis in 74%) admitted in 31 centers lacking on-site revascularization facilities, early angina associated with transient electrocardiographic (ECG) changes was documented in 332 (14%). At multivariate analysis, preinfarction angina, age > or = 70 years, female gender, and history of infarct were significant predictors of early angina. Though the in-hospital course was free from major cardiac events in 78% of patients after the first anginal episode, reinfarction was more common after early angina (7% vs 2% in patients without, RR 3.1, 95% confidence interval [CI] 1.9 to 5.6; p <0.001), and death occurred in 7% of patients with early angina (vs 5% of patients without, RR 1.4, CI 0.9 to 2.4, p = NS). No demographic or clinical characteristics identified patients who suffered nonfatal reinfarction after angina, and neither the ECG location (infarct zone or remote) nor patterns of ECG changes during angina proved significant predictors of in-hospital reinfarction or death. Early angina emerged as the sole independent predictor of 6-month cumulative reinfarction (12% vs 5% of patients without, RR 2.9, CI 2.0 to 4.4; p <0.0001) and an independent predictor of death (13% vs 7% of patients without early angina, RR 2.3, CI 1.6 to 3.3; p <0.0001). Early postinfarction angina is a powerful prognostic marker. Patients with early postinfarction angina had an unfavourable in-hospital outcome, but the prospective identification of patients at greater risk of major events after angina remains elusive

    Twenty patients with refractory rest angina pectoris were treated with intravenously (IV) administered nitroglycerin (mean dosage, 72.4 micrograms/min; range, 15 to 226 micrograms/min). There was a considerable reduction or abolition in the number of ischemic episodes in 85% of patients without overall substantial changes in heart rate, mean arterial BP, pulmonary capillary wedge pressure (PCWP), and pulmonary arterial mean pressure. However, those patients with an initial PCWP of more than 12 mm Hg or a systolic pressure of more than 130 mm Hg had a substantial reduction in PCWP and systolic BP following IV nitroglycerin. We conclude that IV nitroglycerin may relieve rest angina by different pathophysiologic mechanisms. In some patients, IV nitroglycerin favorably altered the hemodynamic determinants of myocardial oxygen consumption. In others, however, no change in these determinants occurred, suggesting a direct effect on the coronary circulation.

    Treatment of angina pectoris associated with coronary microvascular dysfunction is challenging as the underlying mechanisms are often diverse and overlapping. Patients with type 1 coronary microvascular dysfunction (i.e. absence of epicardial coronary artery disease and myocardial disease) should receive strict control of their cardiovascular risk factors and thus receive statins and ACE-inhibitors in most cases. Antianginal medication consists of ß-blockers and/or calcium channel blockers. Second line drugs are ranolazine and nicorandil with limited evidence. Despite individually titrated combinations of these drugs up to 30 % of patients have refractory angina. Rho-kinase inhibitors and endothelin-receptor antagonists represent potential drugs that may prove useful in these patients in the future.

    Angina pectoris is the symptomatic manifestation of transient myocardial ischaemia. At the most fundamental level, angina arises when myocardial oxygen demand exceeds the ability of the coronary circulation to provide adequate oxygen delivery to maintain normal myocardial metabolic function. In vivo, the balance of oxygen demand and delivery is a complex physiological process that can be altered by a variety of interventions. Lifestyle modification is a cornerstone of cardiovascular disease management, with or without angina. Additional pharmaceutical and physical interventions are usually applied to patients with angina. Mechanisms of action for these interventions include heart rate modulation, vascular smooth muscle relaxation, metabolic manipulation, revascularization, and others. A number of these interventions have overlapping mechanisms that target angina. Additionally, some interventions may directly or indirectly prevent or delay adverse outcomes such as myocardial infarction or death. This review summarizes current evidence for many applied ischaemia treatments documented to modify angina and comments on available evidence relating to improvement in cardiovascular outcomes.

    Ludwig's angina is a life-threatening cellulitis that involves the submandibular and sublingual spaces. It often occurs after an infection of the roots of the teeth. However, modern dental care and use of antibiotics for oral infections have made Ludwig's angina rare. We present here a cancer patient exhibiting the sequential features of bisphosphonate related osteonecrosis of the jaw on bone scan complicating with Ludwig's angina. This report highlights the need for medical practitioners to be alert to these rare combinations in the compromised patient after bisphosphonate therapy. To the best of our knowledge, no case of Ludwig's angina secondary to osteonecrosis of the jaw has been reported.

    Variant angina pectoris, also called Prinzmetal's angina, is a syndrome caused by vasospasms of the coronary arteries. It can lead to myocardial infarction, ventricular arrhythmias, atrioventricular block and even sudden cardiac death. We report the case of a 53 year-old male patient with recurrent episodes of chest pain and arrhythmias in the course of related variant angina pectoris. It is likely that the reperfusion following myocardial ischemia was responsible for the ventricular fibrillation while the ST-segment returned to the baseline. This case showed that potential lethal arrhythmias could arise due to variant angina pectoris. It also indicated that ventricular fibrillation could be self-terminated.

    Cardiac nociceptive afferences are mainly transmitted by sympathetic nervous tracts. After passing the ganglion stellatum and neighbouring ganglia, the nerves enter the dorsal horn of the spinal cord at C8-Th9 (especially Th2-Th6). Here the nerve synapses for the first time, mainly to neurons which run up to the thalamus contralaterally by the tractus spinothalamicus. Apart from atypically localised pain (jaw, head, neck), the nervus vagus is rarely involved in transmitting angina pectoris pain. There is no close relation between peripheral pain localisation and localisation of coronary stenosis or myocardial ischemia areas. The localisation of angina pectoris is decided by viscero-somatic summation (convergence-projection-theory). Almost all the ascending tracts of the tractus spinothalamicus with visceral inflow also receive inflow from somatic afferences, from skin areas of the dermatome from the same segment level, and especially from deep somatic structures such as muscle and ligaments (Head's zones). Additional reflex mechanisms, where the efferent part is probably sympathetic, explain transferred effects in the matching dermatome such as hypothermic skin zones, cutaneous hyperalgesia, higher pressure sensitivity of the muscles and occasionally even dystrophic changes. The amount of spinal visceral afferences is relatively small (only 1.5-2.5% of all somatic spinal afferences). The low amount, the pronounced divergence and, compared to converging somatic afferences, the larger receptive fields in the organ explain the diffuse, barely localisable character of angina pectoris pain. Cardiac afferences are tonically and phasically inhibited at spinal and supraspinal levels, especially by descending tracts. This explains why angina pectoris can be missing in spite of pronounced peripheral nociceptive impulse rates. Patients with silent myocardial ischemia have a higher central pain threshold than patients with symptomatic myocardial ischemia. Endogenous opioids

    Psoriasis is a chronic, inflammatory, recurrent, genetically determined dermatitis that affects the skin and joints. Many patients affected by this condition seek alternatives and complementary treatment options such as herbal medicines. In order to establish the safety of these products, trials, according to medical standards should be performed to provide the highest quality of data. The aim of this study was to assess the efficacy and safety of an Australian series of herbal skincare products [Dr. Michaels® (Soratinex®) skin-care products for psoriasis] for the management of stable chronic plaque psoriasis. We studied 142 patients (68 females and 74 males) with mild to moderate, stable, chronic plaque psoriasis and they were randomly assigned to either verum or control group. Exclusion criteria were: severe psoriasis, arthropathic psoriasis, intertriginous psoriasis, palmoplantar psoriasis, use of any antipsoriatic treatment and any medication which could influence or interfere with the course of the disease. Both groups consisted of a cleansing gel, an ointment and an oil blend (skin conditioner), packed in neutral bottles, used twice daily for all lesions except the scalp, for 8 weeks. As control products, we used compositions of well-known neutral ointments and medicinal bathing oil. Assessment, using the Psoriasis Activity Severity Index (PASI) scores, was done before treatment and after 2, 4, 6 and 8 weeks. Patient improvement was determined by the percentage reduction of the PASI scores. Statistical analysis was carried out using the Mann-Whitney-U Test with SPSS for Windows. Our investigation demonstrates that complementary methods can play a role in dermatologic therapy as long as they undergo standardised clinical trials and fulfil the basic requirements such as product safety and quality assurance. This study shows that Dr Michaels (Soratinex®) herbal skin-care products improve mild to moderate stable chronic plaque psoriasis significantly.

    Takayasu arteritis is a form of vasculitis that involves the aorta, its major branches, and the pulmonary arteries. Coronary artery involvement is not uncommon, and most frequently includes the ostia and proximal segments. Early diagnosis of Takayasu arteritis is difficult since it is a rare disease and is accompanied by various nonspecific clinical symptoms. However, recent advances in imaging modalities-including magnetic resonance angiography, computed tomography (CT), sonography, and fluoro-deoxyglucose positron emission tomography (FDG-PET)/CT Isobe (2013) [2]-have facilitated earlier and more accurate diagnoses of this condition. Here we report a case in which imaging revealed stenosis in the ostia of the coronary artery.

    A patient had total occlusion of the left main coronary artery that was proved by coronary arteriography. The patient was initially seen with clinical signs of congestive heart failure but without symptoms of angina pectoris or ECG evidence of myocardial infarction. The patient's extensive right-to-left coronary artery collaterals may have contributed to the absence of chest pain. Because of the severe left ventricular dysfunction and the absence of chest pain, the patient was treated with medical therapy. Six months after the cardiac catheterization, he was alive and well under New York Heart Association functional classification II.

    Physicians often consider angina pectoris to be synonymous with myocardial ischemia. However, the relationship between angina and myocardial ischemia is highly variable and we have little insight into the sources of this variability. We investigated the relationship of inducible myocardial ischemia on SPECT stress perfusion imaging to angina reported with routine daily activities during the previous four weeks (N=788) and to angina reported during an exercise stress test (N=371) in individuals with confirmed or suspected coronary disease referred for clinical testing. We found that angina experienced during daily life is more strongly and consistently associated with psychological distress and the personal threat associated with angina than with inducible myocardial ischemia. In multivariable models, the presence of any angina during routine activities over the prior month was significantly associated with age, perceived risk of myocardial infarction, and anxiety when compared to those with no reported angina in the past month. Angina during daily life was not significantly associated with inducible myocardial ischemia on stress perfusion imaging in bivariate or multivariable models. In contrast, angina experienced during exercise stress testing was significantly related to image and ECG ischemia, though it was also significantly associated with anxiety. These results suggest that angina frequency over the previous four weeks is more strongly associated with personal threat and psychosocial distress than with inducible myocardial ischemia. These results lend support to angina treatment strategies that aim to reduce threat and distress as well as to reduce myocardial ischemia.

  10. Resolution of Angina Pectoris and Improvement of the Coronary Flow Reserve after Ranolazine Treatment in a Woman with Isolated Impaired Coronary Microcirculation

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available In a 61-year-old woman with well controlled arterial hypertension, hypercholesterolemia, and smoke and suffering from recurrent angina pectoris despite angiographically normal epicardial coronary vessels and maximal therapy, the replacement of nitrates with novel antiangina drug ranolazine, after 6-month therapy, induced a complete relief of angina and a relevant rising of the transthoracic Doppler-derived coronary flow reserve (CFR. The present clinical case underlines therefore how in patients with chronic ischemic heart disease without epicardial coronary stenosis ranolazine can induce an improvement till the complete solution of the angina symptoms and a substantial increase of CFR as expression of the enhancement of the microvascular coronary function. The improvement of both symptoms and coronary microvascular function is strictly linked to the mechanism of action of the drug. Ranolazine induces in fact a reduction of the intracellular late sodium current that leads to a reduction of the intracellular calcium concentration thus producing a better myocardial diastolic relaxation process which in its turns enhances the myocardial perfusion. The ranolazine acts therefore as a lusitropic drug that improves the diastolic dysfunction and the segmental ischemia thus affecting one of the first steps of the ischemic cascade.

    1997-11-19

    We present a case report of a 57 year old woman with recurrent chest pain, initially exclusively at exercise and later also at rest. This led to an emergency hospitalization for suspected myocardial infarction. As there were no enzymatic and electrocardiographic signs of acute infarction she was treated, as unstable angina pectoris. Coronary angiography revealed but a modest coronary atheromatosis without significant coronary stenosis. Therefore her symptoms were interpreted as primary manifestation of an intermittant Left Bundle Branch Block (LBBB) with changing heart-rate dependency. A majority of patients with LBBB and chest pain have a relevant Coronary Artery Disease (CAD). There is a small number of reports in literature about patients with intermittant LBBB without significant CAD but with both typical (exercise-induced) and atypical (at rest) chest pain. Special features of our case are presentation of LBBB as unstable angina, documentation of an intermittant LBBB with changing heart-rate dependency and heart-rate-dependent supranormal conduction in the left bundle branch. We review some important aspects of LBBB with regard to this case.

    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.

Methods: Using literature databases, we conducted a thorough and systematic retrieval of randomized controlled trials (RCTs) that using Salvianolate injection for treating UAP. The Cochrane Risk of Bias Assessment Tool was used to evaluate the methodological quality of the RCTs, and then the data were extracted and meta-analyzed by RevMan5.2 software. Results: A total of 22 RCTs with 2050 participants were included. The meta-analysis indicated that the combined use of Salvianolate injection and western medicine (WM) in the treatment of UAP can achieve a superior effect in angina pectoris total effective rate (risk ratio [RR] = 1.22, 95% confidence interval [CI] (1.17, 1.27), Z = 10.15, P Adverse drug reactions (ADRs) or adverse drug events (ADEs) were reported in 6 RCTs involving 15 cases; however, there were no serious ADRs/ADEs. Conclusion: Based on the systematic review, the combined use of Salvianolate injection and WM in the treatment of UAP can achieve a better effect; however, there was no definitive conclusion about its safety. More the large-sample and multicenter RCTs are needed to support its clinical usage. PMID:28002341

    Full Text Available Introduction: Unstable angina as a clinical condition includes a major group of patients manifested with acute coronary syndrome. Misdiagnosis of this clinical syndrome causes myocardial infarction (MI and death. Conventional and advanced forms of treatment are used with the aim of rapid stabilization of unstable angina. Although infusion of glucose - insulin - potassium (GIK solution has had good results in acute MI, no major trial has studied its effect in unstable angina. The main goal of this study was evaluation of the effectiveness of GIK solution on prognosis of hospitalized unstable angina patients. Methods: This randomized clinical trial included patients with class II and III unstable angina (two groups of 94 patients, each with a mean age of 62.47±13.20 years and Female /Male ratio of 1.35 admitted in the CCU’s of Yazd from September 2003 to May 2004 . Results: There was no significant difference between the study and control groups regarding mean age, sex ratio and unstable angina class (P=0.15, P=0.77 and P=0.76. The study group had significant reduction in recurrent chest pain and duration of hospitalization (P=0.001 and P=0.02. The most common adverse effect of GIK solution was pain at infusion site. Conclusion: Use of GIK solution causes early stabilization of unstable angina patients without any significant or life threatening adverse effect.

    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.

    Dilatation of the pulmonary artery may lead to the compression of adjacent structures. Of those, the extrinsic compression of the left main coronary artery is the most worrisome. We present the case of a 48-year-old woman who was diagnosed with pulmonary artery dilatation due to severe, thromboembolic pulmonary hypertension. She also had angina and coronary angiography revealed a 70% ostial stenosis of the left main coronary artery. The presence of this isolated lesion in a young woman without risk factors for atherosclerosis suggests extrinsic compression of the left main coronary artery by the dilated pulmonary artery as the likely mechanism. The patient underwent direct stenting of the left main coronary stenosis with a good result.

    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.

    Chest pain is a hallmark symptom in patients with unstable angina pectoris (UAP). However, little is known regarding the prevalence of an atypical presentation among these patients and its relation to subsequent care. We examined the medical records of 4,167 randomly sampled Medicare patients hospitalized with unstable angina at 22 Alabama hospitals between 1993 and 1999. We defined typical presentation as (1) chest pain located substernally in the left or right chest, or (2) chest pain characterized as squeezing, tightness, aching, crushing, arm discomfort, dullness, fullness, heaviness, pressure, or pain aggravated by exercise or relieved with rest or nitroglycerin. Atypical presentation was defined as confirmed UAP without typical presentation. Among patients with confirmed UAP, 51.7% had atypical presentations. The most frequent symptoms associated with atypical presentation were dyspnea (69.4%), nausea (37.7%), diaphoresis (25.2%), syncope (10.6%), or pain in the arms (11.5%), epigastrium (8.1%), shoulder (7.4%), or neck (5.9%). Independent predictors of atypical presentation for patients with UAP were older age (odds ratio 1.09, 95% confidence interval 1.01 to 1.17/decade), history of dementia (odds ratio 1.49, 95% confidence interval 1.10 to 2.03), and absence of prior myocardial infarction, hypercholesterolemia, or family history of heart disease. Patients with atypical presentation received aspirin, heparin, and beta-blocker therapy less aggressively, but there was no difference in mortality. Thus, over half of Medicare patients with confirmed UAP had "atypical" presentations. National educational initiatives may need to redefine the classic presentation of UAP to include atypical presentations to ensure appropriate quality of care.

    Cardiac troponin T (cTnT) is a regulatory contractile protein not normally found in blood. Its detection in the circulation has been shown to be a sensitive and specific marker for myocardial cell damage. In this study, we used a second-generation enzyme immunoassay for cTnT to determine whether its presence in the serum of patients with unstable angina was a prognostic indicator. Thirty patients with unstable angina pectoris (UAP) and 30 patients with Q-wave acute myocardial infarction (AMI) were screened for serum CK-MB activity and cTnT at 6, 12, 24 and 48 hours after the onset of chest pain, All of the mean concentrations of CK-MB activity determined in UAP patients were less than the upper limit of normal (25 U/L). Meanwhile, the mean concentration of cTnT at 6, 12, 24 and 48 hours after onset of chest pain were higher than the cutoff values (0.1 microg/L), We found that one third of UAP patients had serum cTnT at the time of admission more than 0.1 microg/L and that these groups of patients were associated with a high risk for cardiac events. Our results suggested that patients with elevated serum cTnT could be considered as high-risk patients for developing myocardial infarction, Patients with normal cTnT levels and a low or intermediate clinical risk could be stabilized and further stratified noninvasively.

    A controlled double blind clinical trial has been conducted in 16 patients with "angina pectoris" in order to investigate the effect of Perexiline maleate as compared with prenilamine. Perexiline at the dose of 400 mg/die and prenilamine at the dose of 120 mg/die have been administered over a period of 4 weeks each. Between these periods placebo has been administered for two weeks. The number of attacks of angina and the number of tablets of nitroglycerine used per week by the patient during each period has been used for the evaluation. Furthermore ECG at rest and after exercise has been performed every two weeks. Our results statistically evaluated show a definite antianginal effect of Perexiline. According to our experience Perexiline should be considered the drug of choise in the treatment of angina complicated by bradicardia, left ventricular failure, bronchospasm, and in angina unresponsive to other drugs.

    BACKGROUND: Angina pectoris accompanied by transient ST-segment changes during the in-hospital phase of acute myocardial infarction (AMI) is a well established marker of subsequent cardiac death and reinfarction. HYPOTHESIS: This study was undertaken to record the prognostic significance of angina...... on study treatment 1 month after discharge. Of these patients, 311 (39%) reported chest pain during the first month following discharge. RESULTS: Patients with angina pectoris had a significantly increased risk of reinfarction [hazard 1.71; 95%-confidence limit (CL): 1.09, 2.69] and increased mortality...... risk which, however, only reached borderline statistical significance (hazard 1.52; 95%-CL: 0.96, 2.40).

    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.

    Prognosis of unstable angina pectoris is related to admission EKG changes and prompt symptom control. The aim of this study was to compare the clinical effects of intravenous diltiazem (DTZ) or nitroglycerin (NTG) in patients with unstable angina pectoris. We studied 43 patients admitted to the hospital with a history of rest angina within the last 48 hours, associated with EKG evidence of ischemia. All subjects received intravenous heparin and oral aspirin, 23 were randomly assigned to receive intravenous DTZ and 20 to receive intravenous NTG. Both groups had similar baseline features and the endpoints of treatment were recurrence of angina, myocardial infarction, death during hospitalization and secondary side effects. Treatment with DTZ, when compared to NTG, resulted in a significant reduction of recurrent angina (8.7 and 59% respectively; p bradicardia with DTZ (28% of patients). In each group, one patient had a myocardial infarction and one patient died. It is concluded that intravenous DTZ reduces myocardial ischemia to a greater extent than NTG and can be safely used in patients with unstable angina pectoris.

The patients were grouped as follows; 13 of dilated cardiomyopathy (DCM) group, 13 of hypertrophic cardiomyopathy (HCM) group and the 8 of stable effort angina. The control group was of 18 cases with normal {sup 201}TlCl (Tl) cardiac scintigraphy and chest pain. The blood was collected before the exercise tolerance by the ergometer, and the concentration of ANP, BNP and NE in blood was measured by the RIA method and the HPLC method, respectively. Patients were intravenously administrated 111Mbq of {sup 123}I-MIBG at rest and early images of the {sup 123}I-MIBG scintigraphy were taken after 15 min and late images after 3 hours. Washout rate (WR) and heart-mediastinal uptake rate (H/M) were obtained from late images. Compared with the control group, the DCM group showed the high levels of ANP and BNP (p<0.01) and the low level of NE (p=0.025). The HCM group showed the high level of BNP (p<0.001) and the low level in H/M. There were no differences in ANP, NE, H/M and WR between angina pectoris and the control. The correlations among BNP and H/M or WT were significant in all cases. BNP may be a remarkable index for sympathetic dysfunction. (K.H.)

In the case of ten dimensional supergravity, it is possible, at least for a portion of the phase space, to achieve a stable compactification without fine-tuning by including the contribution of fermionic condensates to the monopole configurations. 23 refs., 2 figs.

    Full Text Available Context: Although the role of proteinase/antiproteinase imbalance in chronic obstructive pulmonary disease (COPD due to tobacco is well established, information in COPD due to nontobacco etiology is sparse. Aims: To assess the variability in metalloproteinase activity in COPD related to tobacco and nontobacco causes. Settings and Design: This is a hospital-based, prospective, observational study. Subjects and Methods: Serum matrix metalloproteinase-9 (MMP-9 and tissue inhibitor of metalloproteinases-1 (TIMP-1 were estimated in 200 subjects divided equally into four groups, i.e. COPD in tobacco smokers, COPD in nonsmokers but with exposure to biomass-related indoor air pollution, smokers without COPD, and nonsmoking healthy controls. Anthropometric skinfold measurements, quality of life (QOL using St. George Respiratory Questionnaire, and exercise capacity using the 6-min walk test (6-MWT were carried out. Groups were compared using analysis of variance and Kruskal–Wallis plus Mann–Whitney U-test to assess differences between groups. The Chi-square and Fisher's exact tests were used to evaluate associations among categorical variables. Spearman's rank correlation was calculated to assess the correlation between data. Results: Patients with COPD due to either tobacco or nontobacco etiology were older, more malnourished, had worse QOL, and poorer exercise capacity compared to non-COPD subjects. Triceps, subscapular, and suprailiac skinfold thicknesses were less in smokers with COPD than biomass-related COPD. MMP-9 and TIMP-1 levels were similar across all groups. TIMP-1 significantly correlated with 6-MWT among all groups. Conclusions: The protease-antiprotease balance in COPD is similar irrespective of the presence or absence of tobacco exposure but is related to poor exercise capacity.

    Objectives To explore the basic heart functional state and cardiac reserve function of patients with different types of unstable angina pecto ris (UAP) and observe the relations between the heart function and severity of coronary arterial disease. Methods 70 eases with UAP were enrolled including 25 patients with angina decubitus (AD), 23 patients with mixed angina (MA) , and 22 patients with accelerated effort angina (AEA). All patients underwent a series of examination such as UCG, ECT, hemodynamics and volume-loading test. The patients were divided group. We assessed the basic heart function and cardiac reserve function of patients with different types of UAP and also observed the relations between coronary (48%). 43 percent of the patients with mixed angina had systolic dysfunction and other 43 percent of them had normal cardiac function. However, patients with nary capillary wedge pressure of positive patients rose,at the same time cardiac index fell to the extreme instantaneously after loading in volume-loading test and then they restored to the basic level until 60 minutes.However, both PCWP and CI of the negative patients arteriography show: there are 41% of patient with three-vessel disease, 50% with two-vessel disease,9% single vessel disease and left main narrowing 22.7% in AEA. There are separately 76%, 24%,were separately compared with AD, AEA/AD: P < 0. 05(P = 0.031); MA/AD: P < 0.01 (P = 0. 000313). Conclusions Most of patients with the above three types of unstable angina pectoris suffered from the basic heart dysfunction and cardiac reserve dysfunction which might participate in the occurrence and development of unstable angina pectoris. In angiography, there are the most three-vessel diseases in AD that are, therefore, the most severe UAP.

    In this study, we compared the effects of two analgesic regimens on perioperative nitric oxide index (NOx) and the likelihood of subsequent development of chronic postsurgical pain (CPSP) after breast surgery and sought to determine the association among early postoperative pain, NOx, and the likelihood of subsequent development of CPSP. Twenty-nine consecutive ASA I or II patients undergoing breast surgery with axillary clearance were randomly allocated to one of two groups. Patients in group S (n = 15) received a standard intraoperative and postoperative analgesic regimen (morphine sulfate, diclofenac, dextropropoxyphene hydrochloride + acetaminophen prn). Patients in group N (n = 14) received a continuous paravertebral block (for 48 h) and acetaminophen and parecoxib (followed by celecoxib up to 5 days). Visual analog scale pain scores at rest and on arm movement were recorded regularly until the fifth postoperative day. A telephone interview was conducted 10 wk postoperatively. The McGill Pain Questionnaire was used to characterize pain. NOx was estimated preoperatively, at the end of surgery, 30 min and 2, 4, 12, 24, 48 h postoperatively. Twelve (80%) patients in group S and no patient in group N developed CPSP (P = 0.009). Compared with patients with a pain rating index > or =1 (n = 18) 10 wk postoperatively, patients with a pain rating index = 0 (n = 11) had lesser visual analog scale pain scores on movement at each postoperative time point from 30 min until 96 h postoperatively (P < 0.005) and at rest 30 min (0.6 +\\/- 1.5 versus 30.2 +\\/- 26.8; P = 0.004), 4 h (2.3 +\\/- 7.5 versus 19.0 +\\/- 25.8; P = 0.013), 8 h (4.4 +\\/- 10.2 versus 21.4 +\\/- 27.0; P = 0.03) and 12 h (0.7 +\\/- 1.2 versus 15.4 +\\/- 27.0; P = 0.035) postoperatively. NOx values were greater in group N compared with group S 48 h postoperatively (40.6 +\\/- 20.1 versus 26.4 +\\/- 13.5; P = 0.04).

  9. Stable beams

    Stable beams: two simple words that carry so much meaning at CERN. When LHC page one switched from "squeeze" to "stable beams" at 10.40 a.m. on Wednesday, 3 June, it triggered scenes of jubilation in control rooms around the CERN sites, as the LHC experiments started to record physics data for the first time in 27 months. This is what CERN is here for, and it’s great to be back in business after such a long period of preparation for the next stage in the LHC adventure.   I’ve said it before, but I’ll say it again. This was a great achievement, and testimony to the hard and dedicated work of so many people in the global CERN community. I could start to list the teams that have contributed, but that would be a mistake. Instead, I’d simply like to say that an achievement as impressive as running the LHC – a machine of superlatives in every respect – takes the combined effort and enthusiasm of everyone ...

    To assess the presence and location of presynaptic myocardial sympathetic abnormality in patients with vasospastic angina, iodine-123 labelled metaiodobenzylguanidine (MIBG) single-photon emission tomography (SPET) was performed. Fifty patients suspected of having vasospastic angina pectoris were enrolled in the study. All patients underwent a provocative test with intracoronary ergonovine infusion during coronary angiography, in which 99%-100% obstructive spasm was defined as a positive result. Twenty-five patients were diagnosed as having vasospastic angina based on a positive provocative test. MIGB SPET was performed at 20 min and 3 h after administration of 111 MBq of MIBG. On early images, only 5 of 25 patients with vasospastic angina showed a mild reduction in MIBG uptake, whereas 3-h delayed images demonstrated MIBG abnormality in 20 patients (80%). The location of the MIBG abnormality was completely or partially consistent with the spastic coronary territory in 18 patients. On the other hand, only 4 of 25 patients (16%) with a negative provocative test demonstrated reduced MIBG uptake. Accordingly, positive and negative predictive values of MIBG SPET for the provocative test were 83% (20/24) and 81% (21/26) respectively. In conclusion, MIBG scintigraphy with SPET can permit the non-invasive detection and evaluation of suspected vasospastic angina. (orig.)

    The syndrome "unstable angina" (UA) covers a broad spectrum of patients. In this study we tried to determine the relationship between the severity of UA and angiographic findings. We evaluated 1000 consecutive patients undergoing coronary angiography. Those with the clinical diagnosis "UA" were included in the study. In a retrospective analysis of their records we categorized them, using the Braunwald-classification for determination of the severity of the disease. 352 patients were include, 209 men and 143 women, the mean age was 65 years. 47% met Braunwald-Class I, 26% Class II and 27% Class III. Coronary single-vessel disease was present in 29%, two-vessel disease in 20%, three-vessel disease in 25%, normal coronaries in 13% and coronary atherosclerosis without critical narrowing in 13%. Left ventricular function was preserved in 72%, mild systolic dysfunction was found in 10%, moderate in 13% and severe in 5%. There was no overall correlation between clinical presentation (Braunwald-Classes) and angiographic findings. Women showed a similar distribution of Braunwald-Classes, but significantly more coronary arteries without critical obstruction. In patients with reduced systolic function the percentage of multi-vessel disease was significantly higher, the percentage without relevant coronary artery narrowing was significantly lower. 1) The lack of overall correlation between clinical presentation and angiographic findings supports the importance of coronary angiography in the evaluation of patients with UA. 2) The assessment of women with chest pain is more difficult than of men with regard to coronary heart disease. 3) UA in patients with impaired left ventricular function is a predictor of severe coronary artery disease.

    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.

    Angina pectoris is a common symptom in patients with aortic stenosis without coronary artery disease. To investigate the correlates of angina pectoris, echocardiographic and hemodynamic data from 44 patients with aortic stenosis and no coronary artery disease (mean age 56 +/- 10 years) were analyzed. Twenty-three patients had no angina pectoris and 21 patients had angina pectoris. The ratio of the diastolic pressure-time index (area between the aortic and left ventricular pressure curves during diastole) to the systolic pressure-time index (area under the left ventricular pressure curve during systole), an index of the oxygen supply/demand ratio, was not different in patients with or without angina pectoris. There were no differences between patients with and without angina pectoris in echocardiographically determined wall thickness, chamber size, systolic and diastolic wall stress and left ventricular mass; in electrocardiographically defined voltage; and in hemodynamically defined aortic valve area, transaortic gradient and stroke work index. Thus, echocardiographic and hemodynamic measurements at rest are not significantly different in the presence or absence of angina pectoris in patients with aortic stenosis. Dynamic data appear to be essential for evaluation of the mechanisms of angina pectoris in patients with aortic stenosis.

    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.

    Angina pectoris is a treatable symptom that is associated with mortality and decreased quality of life. Angina eradication is a primary care goal of care after an acute myocardial infarction (AMI). Our aim was to evaluate factors influencing angina pectoris 1 year after an AMI.From January 2005 to December 2013, 1547 patient received primary percutaneous intervention in our hospital for an acute ST-segment elevation myocardial infarction (MI). Of these patients, 1336 patients did not experience post-MI angina during a 1-year follow-up, and 211 patients did. Univariate and multivariate logistic regression analyses were performed to identify the factors influencing angina pectoris 1 year after an AMI. Propensity score matched analyses were performed for subgroups analyses.The average age of the patients was 61.08 ± 12.77 years, with a range of 25 to 97 years, and 82.9% of the patients were male. During 1-year follow-up, 13.6% of the patients experienced post-MI angina. There was a longer chest pain-to-reperfusion time in the post-MI angina group (P = 0.01), as well as a higher fasting sugar level, glycohemoglobin (HbA1C), serum creatinine, troponin-I and creatine kinase MB (CK-MB). The post-MI angina group also had a higher prevalence of multiple-vessel disease. Manual thrombectomy, and distal protective device and intracoronary glycoprotein IIb/IIIa inhibitor injection were used frequently in the no post-MI angina group. Antiplatelet agents and post-MI medication usage were similar between the 2 groups. Multivariate logistic regression analyses demonstrated that prior MI was a positive independent predictor of occurrence of post-MI angina. Manual thrombectomy use and drug-eluting stent implantation were negative independent predictors of post-MI angina. Higher troponin-I and longer chest pain-to-reperfusion time exhibited a trend toward predicting post-MI angina.Prior MIs were strong, independent predictors of post-MI angina.

    The effect of nifedipine on effort angina was investigated by means of exercise tests with bycicle ergometer and compared, in the same patients, with the effects of a nitroderivative and a betablocking agent. Five patients with stable effort angina entered the study, after an hemodynamic and contrasto-graphic control. According to the protocol of a latin square 5 X 5, all the patients received in a random sequence the following treatments: placebo, 1 c. orally; isosorbide dinitrate, 5 mg sublingually; propranolol, 40 mg orally; nifedipine, 10 mg sublingually; nifedipine, 10 mg orally. No significant change of any of the considered parameters was observed after the placebo. Isosorbide dinitrate and nifedipine produced significant increases of the duration of work before appearance of pain and EKG positivity, and of total work performed before anginal pain. Only the duration of work before EKG positivity was improved by propranolol. The comparisons between treatments showed no significant difference of the effects of the administered doses of isosorbide dinitrate and nifedipine. The improvements observed after propranolol were significantly lower than that observed after isosorbide dinitrate and oral nifedipine. On the basis of the observed changes of cardiac rate, maximal arterial pressure, ejection time index and triple product, the authors evaluate the possible mechanism of action of nifedipine.

    Full Text Available Objective. To study the effects of low-dose and long-term treatment with erythromycin on IL-17 and IL-23, in peripheral blood and induced sputum, in patients with stable chronic obstructive pulmonary disease (COPD. Methods. Patients were randomly divided into placebo-treated group, group A (12 months of additive treatment with erythromycin, N=18, and group B (6 months of additive treatment with erythromycin followed by 6 months of follow-up, N=18. Inflammatory cells in induced sputum, pulmonary function, and the 6-minute walk distance (6MWD were analyzed. Concentrations of IL-17 and IL-23 in peripheral blood and sputum were measured using enzyme-linked immunosorbent assays. Results. After treatment, sputum and peripheral blood concentrations of IL-17 and IL-23 significantly decreased in groups A and B compared with placebo-treated group. There were no significant differences after erythromycin withdrawal at months 9 and 12 in group B compared with placebo-treated group. An increase in 6MWD was observed after treatment. Conclusions. Erythromycin was beneficial and reduced airway inflammation in COPD patients. Underlying mechanisms may involve inhibition of IL-17 and IL-23 mediated airway inflammation. COPD patients treated with erythromycin for 6 months experienced improved exercise capacity. Finally, treatment for 12 months may be more effective than treatment for 6 months.

Early-phase clinical trials suggest that intramyocardial administration of autologous CD34+ cells may improve functional capacity and symptoms of angina. RENEW is a pivotal phase 3 trial designed to determine the efficacy of granulocyte colony-stimulating factor (G-CSF)-mobilized CD34+ stem cells for the treatment for patients with refractory angina and chronic myocardial ischemia. Patients (n = 444) receiving maximally tolerated antianginal therapies and lacking conventional revascularization options with Canadian Cardiovascular Society class III or IV angina and ischemia on stress testing will be randomized 2:1:1 to cell therapy (G-CSF-mediated stem cell mobilization, apheresis, and intramyocardial injection of 1 × 10(5) autologous CD34(+) cells/kg), active control (G-CSF-mediated stem cell mobilization, apheresis, and intramyocardial placebo injection), or open-label standard of care. The primary efficacy end point is change in exercise treadmill time in the treated vs active control patients, with 90% power to detect a 60-second difference in exercise time between cell-treated (n = 200) and active control (n = 100) patients. Key secondary end points include total number of anginal episodes per week and the incidence of independently adjudicated major adverse cardiac events and serious adverse events. RENEW will be the first adequately powered study aimed at definitively determining the efficacy of a cell therapy (intramyocardially delivered autologous CD34+ cells) for improvement of functional capacity in patients with refractory angina.

    Full Text Available Different therapeutic options are being used for chronic coronary artery disease (CAD. We report about a 51-year-old female with CAD and refractory angina pectoris despite maximally tolerated medical therapy and after both percutaneous coronary intervention (PCI and coronary artery bypass grafting (CABG. The patient received cardiac shock wave therapy (CSWT over a period of 6 month. There was no arrhythmia during or after treatment; enzyme levels were normal at all times. PET imaging showed a substantial improvement of myocardial stress perfusion. Since the patient reported that she now was fully capable to deal with her everyday life, further treatment options were postponed. Our case report suggests that ultrasound-guided CSWT is able to improve symptoms and perfusion in ischemic myocardium.

    Full Text Available Introduction. This study was conducted to find that, is there any advantage from (5000 IU/6h in patient with non-Q wave MI and unastable angina. Methods. In a randomized clinical trial two group of patients with non-Q wave MI and unstable angina were compared about their prognosis and management outcomes. In interventional group (n= 145, heparin (5000 IU/6h was administered and in another group (n= 133 no treatment with heparin was used. Duration of chest pain, recurrent angina, intrahospital mortality were indices for patients outcome study. Findings. Anticoagulant complication was not report in any patient in interventional group. There is no significant difference between two groups about prognosis factors. Conclusion. Heparin administration (5000 IU/6h may have not any role in improving management outcome in patient with non-Q wave MI and unastable angina at least in acute phase. So, it is recommended that heparin have been administered to these patients in continuous regimen (1000-1500 U/hour continuously effusion.

    Spinal cord stimulation is currently used to treat refractory angina. Some concerns may arise about the possible interaction concerning the spinal cord stimulator in patients already implanted with a pacemaker or a cardioverter defibrillator. We are going to describe the successful implantation of a spinal cord stimulator in a patient previously implanted with a cardioverter defibrillator.

    Background More than 20% of patients presenting to the cardiac catheterization laboratory with angina have no angiographic evidence of coronary artery disease (CAD). Despite a “normal” angiogram, these patients often have persistent symptoms, recurrent hospitalizations, a poor functional status, and adverse cardiovascular outcomes, without a clear diagnosis. Methods and Results In 139 patients with angina in the absence of obstructive CAD (no diameter stenosis >50%), endothelial function was assessed, the index of microcirculatory resistance (IMR), coronary flow reserve (CFR), and fractional flow reserve (FFR) were measured, and intravascular ultrasound (IVUS) was performed. There were no complications. The average age was 54.0±11.4 years and 107 (77%) were women. All patients had at least some evidence of atherosclerosis based on IVUS examination of the LAD. Endothelial dysfunction (a decrease in luminal diameter of >20% after intracoronary acetylcholine) was present in 61 patients (44%). Microvascular impairment (an IMR ≥25) was present in 29 patients (21%). Seven patients (5%) had an FFR ≤0.80. A myocardial bridge was present in 70 patients (58%). Overall, only 32 patients (23%) had no coronary explanation for their angina, with normal endothelial function, normal coronary physiologic assessment, and no myocardial bridging. Conclusions The majority of patients with angina in the absence of obstructive CAD have occult coronary abnormalities. A comprehensive invasive assessment of these patients at the time of coronary angiography can be performed safely and provides important diagnostic information which may affect treatment and outcomes.

    A challenge of modern cardiovascular medicine is to find new, effective treatments for patients with refractory angina pectoris, a clinical condition characterized by severe angina despite optimal medical therapy. These patients are not candidates for surgical or percutaneous revascularization. Herein we review the most up-to-date information regarding the modern approach to the patient with refractory angina pectoris, from conventional medical management to new medications and shock wave therapy, focusing on the use of endothelial precursor cells (EPCs) in the treatment of this condition. Clinical limitations of the efficiency of conventional approaches justify the search for new therapeutic options. Regenerative medicine is considered the next step in the evolution of organ replacement therapy. It is driven largely by the same health needs as transplantation and replacement therapies, but it aims further than traditional approaches, such as cell-based therapy. Increasing knowledge of the role of circulating cells derived from bone marrow (EPCs) on cardiovascular homeostasis in physiologic and pathologic conditions has prompted the clinical use of these cells to relieve ischemia. The current state of therapeutic angiogenesis still leaves many questions unanswered. It is of paramount importance that the treatment is delivered safely. Direct intramyocardial and intracoronary administration has demonstrated acceptable safety profiles in early trials, and may represent a major advance over surgical thoracotomy. The combined efforts of bench and clinical researchers will ultimately answer the question of whether cell therapy is a suitable strategy for treatment of patients with refractory angina.

    Objective To explore the effects of continuous visiting nursing care on using of inhalation in patients with stable chronic obstructive pulmonary disease ( COPD). Methods Case Nurse made individual plans for the patients of stable COPD before they discharged, offered the healthy knowledge and used continued revisit nursing, which included 2 home revisit and 4 telephones follow-up. Before and after the home follow-up,Case Nurse evaluated the patients' state of using inhalation aerosol. The data was tested with chi-square test. Results The percentage of patients who could use aerosol correctly was 25% before discharge and 95% after the continuous visiting nursing care. The patients can use inhalation aerosol accurately after the continuous visiting nursing care(P <0. 05) . Conclusion The continuous visiting nursing care can efficiently improve the using of inhalation in patients with COPD, increase the clinical effect of inhalation aerosol.%目的 观察延续性随访护理方案对慢性阻塞性肺疾病(COPD)稳定期患者正确使用气雾剂治疗的影响.方法 个案护士对40例COPD稳定期出院的患者于出院前制定个体化的出院计划,提供常规的出院健康教育,并进行出院后延续性随访护理(2次上门访视和4次电话随访).由个案护士使用问卷评估家庭随访前后患者正确使用气雾剂的情况,干预前后的数据采用卡方检验进行统计学分析.结果 出院前患者使用气雾剂的合格率为25%;第2次家庭随访后,患者使用气雾剂合格率为95%,合格率明显高于出院前(P<0.05).结论 延续性随访护理方案可以明显改善稳定期COPD患者使用气雾剂的行为,有效提高患者对正确使用气雾剂的掌握程度,保证药物的临床疗效.

    1985-01-01

    The effects of intravenous nicardipine (2.5 mg) on the left ventricular (LV) inotropic state, LV metabolism, and coronary haemodynamics were analysed in 22 patients with angina pectoris. Measurements were made at fixed heart rate (atrial pacing), under basal state, and during a cold pressor test. After nicardipine, coronary blood flow and oxygen content in the coronary sinus increased significantly. The indices of inotropic state increased slightly, and the rate of isovolumic LV pressure fall improved. Myocardial oxygen consumption was unchanged despite the significant reduction in pressure-rate product, but LV lactate uptake increased, particularly during the cold pressor test. When nicardipine was administered after propranolol, the indices of inotropic state were unaffected. The lack of direct effect of nicardipine on LV inotropic state was further confirmed by intracoronary injection of 0.1 and 0.2 mg in a separate group of 10 patients. It is concluded that the nicardipine-induced coronary dilatation seems to improve perfusion and aerobic metabolism in areas with chronic ischaemia, resulting in reduced lactate production and augmented oxygen consumption.

    The effects of the calcium antagonists nicardipine and nisoldipine on left ventricular (LV) metabolism were analyzed in 32 patients with angina pectoris. Measurements were made at a fixed heart rate under the basal state and during a cold pressor test (CPT). After administration of the drugs, coronary blood flow increased significantly and the mean aortic pressure decreased by 10% (p less than 0.01) in the basal state and by 11% (p less than 0.01) during CPT. Despite the reduction in pressure-rate product, myocardial oxygen consumption was unchanged in the basal state (18 +/- 4 vs 19 +/- 4 ml/min, difference not significant) and during CPT (21 +/- 5 vs 21 +/- 5 ml/min, difference not significant); this discrepancy between a reduced pressure-rate product and an unchanged oxygen consumption was also noted when nicardipine was given after propranolol (0.1 mg/kg; 12 patients). Both agents also increased LV lactate uptake, particularly during CPT (+13 mumol/min, p less than 0.05 vs control CPT) and reduced LV glutamine production. In 10 patients in whom 14C-lactate was infused, the chemical LV lactate extraction ratio increased more than the 14C-lactate extraction ratio after administration of the drugs, indicating a reduction in LV lactate production. The data are consistent with the hypothesis that nicardipine and nisoldipine improve perfusion and aerobic metabolism in chronically ischemic areas, resulting in an augmented oxygen consumption and in a reduced lactate production.

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.

    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.

    2012-08-15

    To compare the features of coronary computed tomography angiography (CCTA) imaging of the patients with acute total occlusion (ATO) of coronary artery with those of chronic total occlusion (CTO). CCTA of 26 patients with complete interruption of the coronary artery in CCTA and occlusion in conventional coronary angiography, were retrospectively analyzed. Discrimination between the ATO group (n = 11, patients with non ST elevation myocardial infarction or unstable angina) and the CTO group (n = 15, patients with stable angina or nonspecific symptom) was arbitrarily determined by clinical diagnosis. Lesion length, remodeling index (RI), plaque density measured by Hounsfield units (HU), plaque composition, percentage attenuation drop across the lesion, and presence of myocardial thinning were evaluated. Comparisons between the ATO and CTO groups revealed significantly shorter lesion length in the ATO group (0.40 cm vs. 1.87 cm, respectively; p = 0.001), and significantly higher RI (1.56 vs. 1.10, respectively; p = 0.004). Plaque density of the ATO group was lower (37.0 HU vs. 104.7 HU, respectively; p < 0.001) and non calcified plaque was frequently seen in the ATO group (72.7% vs. 26.7%, respectively; p = 0.02). Percentage attenuation drop across the lesion was lower for the ATO group (10.92% vs. 25.44%, respectively; p = 0.005). Myocardial thinning was exclusively observed in the CTO group (seven of 15 patients, p = 0.01). CCTA shows various statistically significant differences between the ATO and CTO groups.

    The practice of mindfulness meditation was used in a 10-week Stress Reduction and Relaxation Program to train chronic pain patients in self-regulation. The meditation facilitates an attentional stance towards proprioception known as detached observation. This appears to cause an "uncoupling " of the sensory dimension of the pain experience from the affective/evaluative alarm reaction and reduce the experience of suffering via cognitive reappraisal. Data are presented on 51 chronic pain patients who had not improved with traditional medical care. The dominant pain categories were low back, neck and shoulder, and headache. Facial pain, angina pectoris, noncoronary chest pain, and GI pain were also represented. At 10 weeks, 65% of the patients showed a reduction of greater than or equal to 33% in the mean total Pain Rating Index (Melzack) and 50% showed a reduction of greater than or equal to 50%. Similar decreases were recorded on other pain indices and in the number of medical symptoms reported. Large and significant reductions in mood disturbance and psychiatric symptomatology accompanied these changes and were relatively stable on follow-up. These improvements were independent of the pain category. We conclude that this form of meditation can be used as the basis for an effective behavioral program in self-regulation for chronic pain patients. Key features of the program structure, and the limitations of the present uncontrolled study are discussed.

    Patients who continue to suffer from severe and disabling angina pectoris, despite optimum treatment in terms of conventional pharmacological therapy and/or revascularization procedures, have been termed as having refractory angina pectoris. The future group of patients with refractory angina pectoris will be different from today's patients and represent a 'moving target' as risk factors, efficacy of treatment and indications continue to change. Spinal cord stimulation (SCS) is today considered as first-line treatment of refractory angina pectoris, by the European Society of Cardiology, with an anti-ischemic effect. There is strong evidence for SCS giving symptomatic benefits (decrease in anginal attacks), improved quality of life and improvement of functional status. In addition, SCS seems to be cost effective with a 'break-even' after approximately 15-16 months.

    Women with angina pectoris and abnormal stress test findings commonly have no epicardial coronary artery disease (CAD) at catheterization. The aim of the present study was to develop a risk score to predict obstructive CAD in such patients. Data were analyzed from 337 consecutive women with angina pectoris and abnormal stress test findings who underwent cardiac catheterization at our center from 2003 to 2007. Forward selection multivariate logistic regression analysis was used to identify the independent predictors of CAD, defined by ≥50% diameter stenosis in ≥1 epicardial coronary artery. The independent predictors included age ≥55 years (odds ratio 2.3, 95% confidence interval 1.3 to 4.0), body mass index angina pectoris and abnormal stress test findings. This tool, if validated, could help to guide testing strategies in women with angina pectoris.

    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.

  1. Visceral chest pain in unstable angina pectoris and effects of transcutaneous electrical nerve stimulation. (TENS). A review.

    Science.gov (United States)

    Börjesson, M

    1999-04-01

    A substantial proportion of patients with chest pain referred to hospital, show signs of coronary artery disease. Anginal pain could be conceptualized as a warning signal for coronary artery disease and impending death. But, for many reasons this theory is partly disputed. Firstly, not all ischemic episodes are accompanied by anginal pain (silent ischemia). Secondly, chest pain indistinguishable from true angina pectoris may be the result of other abnormalities of thoracic viscera. Nevertheless acute severe cardiac ischemia often gives rise to anginal chest pain. Unstable angina pectoris is carrying a higher risk for future events in spite of intensive medical treatment. A special problem are patients awaiting coronary intervention because of severe ischemia and maximum medical treatment, who experience ischemic pain. New treatment regimens are needed for these patients. This review discusses the symptom of visceral pain from the heart, angina pectoris, its relation to ischemia and unstable angina pectoris. It also addresses the role of afferent nerve stimulation (transcutaneous electrical nerve stimulation, TENS) in the treatment of severe angina pectoris as well as recent findings of TENS applicability in unstable angina.

    Objective: To observe the effectiveness of Modified Nuan Gan Jian Jiao Nang (MNGJ 加减暖肝煎胶囊Modified Liver-Warming Capsule) in treating unstable angina pectoris. Method: Sixty-six eligible cases were assigned randomly into a treatment group and a control group and treated for 3 weeks. Results:MNGJ produced an effect in reducing episodes, improving the abnormal findings in electro-cardiogram (ECG) (P<0.05) significantly, and decreasing myocardial oxygen consumption (P<0.05). In addition, it could decrease the plasma TXB2 level and increase 6-keto-prostaglandin F1α (6-Keto-PGF1α) level (P<0.01). Conclusion: MNGJ was quite effective in treating unstable angina pectoris, suggesting that the treatment of the disease could start from the liver.

    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.

    This study was undertaken to assess if the introduction of new angioplasty devices (autoperfusion balloon catheters, stent and atherectomy) could ameliorate early and late results of prompt percutaneous transluminal coronary angioplasty (PTCA) in patients with refractory unstable angina. From January 1993 to June 1995, 59 of 278 patients (14 female, 45 male; mean age: 61 +/- 10 years; range: 38-78) admitted to our Coronary Care Unit with the diagnosis of unstable angina had more than one episode of chest pain at rest with dynamic electrocardiographic ST-T changes and without signs of cardiac necrosis while on medical therapy including oxygen, aspirin, heparin, nitroglycerin and either a beta-blocker or a calcium-antagonist. Coronary angiography was performed within 48 h from the last ischemic attack and a culprilesion technically suitable for PTCA was identified. PTCA was performed in 73 lesions. Elective stent implantation was considered for 16 type B or C lesions in 14 patients. The procedure was initially successful in 52/59 patients (88%), uncomplicated unsuccessful in 4/59 (7%) and complicated in 3/59 (5%). Elective stent insertions were all successful (16/16, 100%). All successfully treated patients were followed up for a mean of 12 +/- 7 months (range: 6-27): 2/52 patients (3.8%) suffered from non-transmural myocardial infarction, 14/52 (26.9%) had a recurrence of angina and 2/52 (3.8%), asymptomatic, had a positive stress test. We conclude that prompt PTCA in refractory unstable angina using 1990s 'state of the art' equipment compares favorably to previous study and that stent delivery might become the elective treatment of complex lesions in this subset of patients.

    Although coronary vasospasm can contribute to the development of unstable angina, the definite diagnostic method has not been established. The purpose of this study was to determine if ergonovine echocardiography (detection of regional wall motion abnormality during bedside ergonovine challenge) after angiographic confirmation of insignificant fixed disease would be useful and safe in detecting coronary vasospasm in patients with unstable angina. After control of chest pain with medications in patients admitted to the coronary care unit under the tentative diagnosis of unstable angina, diagnostic coronary angiography was performed. All patients with normal or insignificant fixed disease underwent ergonovine echocardiography after discontinuation of medications for 4+/-1 days. Among 208 consecutive patients enrolled for this study, 75% (156 of 208) showed significant fixed disease in the angiography. Ergonovine echocardiography was performed in 52 patients with insignificant disease, and coronary vasospasm was documented in 33 (63%, 33 of 52). No serious procedure-related arrhythmia or myocardial infarction occurred. Esophageal motility disorder and hypertrophic cardiomyopathy were diagnosed in 6 and 3 patients, respectively. Chest pain of undetermined etiology was the final diagnosis at discharge in 10 patients (5%, 10 of 208); among them chest pain redeveloped in 2 patients, and repeated ergonovine echocardiography revealed positive results. Our data suggest that among patients with the clinical presentation of unstable angina, coronary vasospasm is the main cause of myocardial ischemia in a considerable number of patients with a normal or near-normal angiogram, and ergonovine echocardiography after confirmation of absence of significant fixed disease is useful and safe for noninvasive diagnosis of coronary vasospasm in this setting.

    Angina pectoris with normal coronary artery on the coronary angiography is an intriguing issue. Intracoronary infusion of acetylcholine has recently been used to test the integrity of endothelial cells. We studied 16 patients with this syndrome. A relationship has been found between the acetylcholine test and the exercise stress test in normotensive patients. The presence of hypertension makes the evaluation of the test more unpredictable, probably because of the damage on the endothelial cells related to systemic hypertension.

    Serum activity of angiotensin-converting enzyme was measured by serial analysis in 19 patients with acute myocardial infarction and in eight patients with angina pectoris. As a rule no changes in enzyme activity occurred during 6 days observations. However, two patients with infarction exhibited a pronounced fall of enzyme activity which could not be related to clinical events. The analysis seems to have no place in the diagnosis and management of patients with myocardial infarction.

    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.

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

    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.

    2015-04-01

    This review article is devoted to the treatment of chronic heart failure (HF) with a new generation drug - ivabradine. It is well known that HF is one of the most frequent reason of high mortality worldwide. HF is characterised by cardiac remodeling, which is central in the pathophysiology of HF including hemodynamic, neurohumoral and neurohormonal mechanisms during its development and established prognostic factor in patients suffered with this disease. Despite the introduction in medical practice of many drugs for the treatment of chronic HF the lethal outcome associated with HF remains high nowadays, which can be explained by complexity of remodeling mechanisms characteristic for development of HF. Ivabradine that has been introduced in medical practice in last decade is a pure heart rate-slowing agent. A large number of studies in patients with cardiovascular disease have demonstrated that heart rate (HR) is a very important and major independent risk factor for prognosis, because lowering of HR reduces cardiac work and diminished myocardial oxygen requirement. It was shown that ivabradine a selective inhibitor of the hyperpolarisation activated sodium chanel (If) is involved in pacemaker generation and responsiveness of the sino-atrial node resulting in HR reduction without negative inotropic action. Ivabradine in chronic HF improves diastolic function and attenuates cardiac tissue hypoxia. Long-term reduction of HR induced by ivabradine reduced remodeling and preserved nitric oxide (NO) bioavailability, resulting from processes triggered early after reduction of HR. The complex therapy including ivabradine promotes HR fall, leading in reduction of attacks of a stable angina and improved quality of life. Ivabradine may target the endothelial NO production via inhibition of protein tyrosine phosphatase 1B leading to endothelial protection. HR reduction by ivabradine reduces oxidative stress, improves endothelial function and prevents development of

    Aim To observe the efficacy of PCI(percutaneous coronary intervention) in patients with stable angina pectoris or acute coronary syndrome according to the disease process. Methods 34 inpatients with angina pectoris were collected from June to July in 2009 and divided into two groups, stable angina and unstable angina, by chest pain. The characteristics of the patients ,their medical history, age and the attacking situation were analyzed. The efficacy of the stent, and disease related risk factors were compared between the two groups ,as well as the relevant laboratory examinations,such as troponin T(cTnTl) ,Chest X-ray,ECG,the stenosis and extent of the lesion of related arteries tested by CAG. Results Among the 34 patients,23 patients were hospitalized as acute coronary syndrome(ACS) and 14 patients(4 patients with stable angina and 10 patients with unstable angina) were for hospital in emergency during 12 hours given the treatment of CAG and PCI. The other 20 patients were treated with non-emergency PCI. One case was relieved by giving conservative medical treatment for the opening and proximal part of LAD without suitable catheter. 8 patients,with three diffuse diseased arteries and without any indication for stent interventional treatment,were transferred for surgery. 2 patients with myocardial bridge were transferred to another hospital. Conclusion Acute coronary syndrome is the most common emergency case in the cardiovascular department,as well as stable angina. The patients with those indications should be cured with CAG and PCI as soon as possible to rehabilitate the myocardial necrosis and improve the prognosis. The increase of blood-sugar and fibrin in unstable angina group is significantly higher than stable angina group. But there is no significant difference in blood-lipid,creatase and development of hypertensive disease between two groups.%目的 观察稳定型心绞痛、急性冠脉综合征患者经皮冠状动脉介入治疗(PCI)临床疗效与

    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.

Methods 43 cases of stable angina pectoris patients and 50 cases of unstable angina pectoris patients were enrolled into the study. 40 cases of healthy volunteers were enrolled into the controlled group.The serum level of hsCRP,MIF and IL-10 was detected by ELISA. The data were then analyzed by One-way ANOVA. Results The serum level of hsCRP (12.53±2.89)mg/L in unstable angina pectoris patients was significantly higher than the controlled group (3.46±1.02)mg/L and stable angina pectoris paiients (4.51±0.98)mg/L (P<0.05). The serum level of MIF (30.94±5.85)μg/L in unstable angina pectoris patients was significantly higher than the controlled group (8.31±1.38)μg/L and stable angina pectoris patients(9.85±1.44)μg/L(P<0.05). There was no significant difference in the level of hsCRP and MIF between the stable angina pectoris and controlled group. The serum level of IL-10 in the unstable and stable angina pectoris group was (19.44±2.11)ng/L and(20.19±2.04) ng/L, respectively. The value was significantly higher than the controlled group (14.89±2.49) ng/L (P<0.05). Conclusion A distinct pattern of inflammatory and anti-inflammatory biomarkers in patients with stable and unstable angina pectoris was observed. The balance of inflammatory and anti-inflammatory response may be associated with the disease progress.%目的 检测稳定型心绞痛患者及不稳定型心绞痛患者外周血血清高敏C反应蛋白(hsCRP)、巨噬细胞移动抑制因子(MIF)、白介素10(IL-10)水平,了解其变化与患者临床分型之间的关系.方法 共收入43例稳定型心绞痛患者和50例不稳定型心绞痛患者,同时收入40例健康志愿者作为对照

    A multicenter study was carried out in order to evaluate the efficacy and tolerability of 2 doses of a nitroglycerin transdermal system (TTS-NG 5 mg/24 h and TTS-NG 10 mg/24 h) on a large population of patients affected by angina pectoris. Nine hundred and seventy three cardiologists enrolled a total of 6,986 patients, 4,290 males and 2,696 females, mean age 61.7 years (range 26-95), 3,283 with effort-angina, 2,062 with mixed angina and 1,641 with angina at rest. Patients whose angina was not satisfactorily controlled by their previous therapy, were given TTS-NG 5 for 1 week in the morning, while continuing their antianginal treatment, with the exception of nitrates which were gradually withdrawn. At the end of this period, patients who responded to the treatment continued taking the same dose for a further 6 weeks, while poor responders were given a double dose of the study medication over the same period. Six thousand two hundred and sixty patients (90%) completed the study. TTS-NG 5 proved to be effective in 2,091 patients (33%) with a reduction in weekly anginal attacks after only 1 week of treatment (from 5.8 +/- 2.9 to 2.4 +/- 2.3). This reduction improved in the following 2 weeks (from 2.4 +/- 2.3 to 1.2 +/- 1.6) and subsequently remained virtually unchanged. Four thousand one hundred and sixty-nine patients (67%), whose angina was not sufficiently controlled by TTS-NG 5 (from 5.0 +/- 2.4 to 4.3 +/- 2.8), received double the dose at the end of the first week. TTS-NG 10 brought about a reduction in weekly anginal symptoms during the 2nd and the 3rd week (from 4.3 +/- 2.8 to 2.0 +/- 2.2), with a further decrease during the following 2 weeks (from 2.0 +/- 2.2 to 1.1 +/- 1.7). The reduction in anginal attacks was of the same extent both during the day and the night, thus suggesting that the drug is effective throughout 24 hours. A similar pattern was observed in the reduction of the number of anginal attacks weighted by their severity, the severity of attacks

    We determine which Boolean stable law is freely infinitely divisible and which is not. Some positive Boolean stable laws and a mixture of them have completely monotonic densities and they are both freely and classically infinitely divisible. Freely infinitely divisible Boolean stable laws and the corresponding free stable laws are non trivial examples whose free divisibility indicators are infinity.

    Full Text Available Objective. To provide a systematic review to evaluate the effectiveness and safety of Xuesaitong soft capsule (XST in treating unstable angina (UA. Methods. An extensive search of 6 medical databases was performed up to August 2013. Randomized controlled trials (RCTs involving XST alone or combined with conventional drugs versus conventional drugs were included. A meta-analysis of reduction of angina symptoms and electrocardiogram (ECG improvement was performed to evaluate the effects of XST on UA. Results. After researching, a total of 6 RCTs with 716 participants were included. Our review showed that XST combined with conventional drugs had significant effect on relieving angina symptoms (RR: 1.14 [1.07,1.22]; P=0.0001 and improving ECG (RR: 1.26 [1.12,1.42]; P=0.0001 compared with conventional drugs alone. Conclusions. XST appears to have beneficial effects on improvement of ECG, reduction of angina symptoms, and decreasing the frequency and duration of angina attack in participants with UA. However, the findings should be interpreted with caution due to the poor methodological quality of the included trials.

    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.

    Full Text Available OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment undergoing coronary angioplasty with stent placement. These 74 patients were compared with 31 patients with stable coronary syndromes (stable angina or stable silent ischemia undergoing the same procedure. RESULTS: No death and no need for revascularization of the culprit artery occurred in the in-hospital phase. The incidences of acute non-Q-wave myocardial infarction were 1.4% and 3.2% (p=0.6 in the unstable and stable coronary syndrome groups, respectively. In the late follow-up (11.2±7.5 months, the incidences of these events combined were 5.7% in the unstable coronary syndrome group and 6.9% (p=0.8 in the stable coronary syndrome group. In the multivariate analysis, the only variable with a tendency to significance as an event predictor was diabetes mellitus (p=0.07; OR=5.2; 95% CI=0.9-29.9. CONCLUSION: The in-hospital and late evolutions of patients with unstable coronary syndrome undergoing angioplasty with intracoronary stent implantation are similar to those of the stable coronary syndrome group, suggesting that this procedure is safe and efficacious when performed in unstable coronary syndrome patients.

    Lipid metabolites are indispensable regulators of physiological and pathological processes, including atherosclerosis and coronary artery disease (CAD). However, the complex changes in lipid metabolites and metabolism that occur in patients with these conditions are incompletely understood. We performed lipid profiling to identify alterations in lipid metabolism in patients with angina and myocardial infarction (MI). Global lipid profiling was applied to serum samples from patients with CAD (angina and MI) and age-, sex-, and body mass index-matched healthy subjects using ultra-performance liquid chromatography/quadruple time-of-flight mass spectrometry and multivariate statistical analysis. A multivariate analysis showed a clear separation between the patients with CAD and normal controls. Lysophosphatidylcholine (lysoPC) and lysophosphatidylethanolamine (lysoPE) species containing unsaturated fatty acids and free fatty acids were associated with an increased risk of CAD, whereas species of lysoPC and lyso-alkyl PC containing saturated fatty acids were associated with a decreased risk. Additionally, PC species containing palmitic acid, diacylglycerol, sphingomyelin, and ceramide were associated with an increased risk of MI, whereas PE-plasmalogen and phosphatidylinositol species were associated with a decreased risk. In MI patients, we found strong positive correlation between lipid metabolites related to the sphingolipid pathway, sphingomyelin, and ceramide and acute inflammatory markers (high-sensitivity C-reactive protein). The results of this study demonstrate altered signatures in lipid metabolism in patients with angina or MI. Lipidomic profiling could provide the information to identity the specific lipid metabolites under the presence of disturbed metabolic pathways in patients with CAD.

To analyze the cost effectiveness of the partial agonist of nicotinic receptors, varenicline, in patients with angina who require cardiac interventions. Material and methods. The estimation was conducted using a Markov model based on the results of clinical trials and epidemiological studies. The cost of treatment of complications were calculated on the basis of compulsory medical insurance rates for St. Petersburg in 2011. Results. The varenicline therapy in 70-year-old patients before cardiac surgery reduces hospital mortality at an extremely high cost-effectiveness (the cost of preventing one death - 148.8 thousand rubles. The cost/effectiveness ratio in the analysis for the period of survival of patients in this situation was 31.3 thousand rubles for 1 additional year of life. Life expectancy will be increased by an average of 0.147 years. Analysis for the period of survival of 50-year-old patients has shown that in patients after cardiac surgery cost-effectiveness of varenicline is extremely high (in the analysis from the perspective of the health care system the cost/effectiveness ratio was 36.0 thousand rubles for 1 additional year of life, in the analysis, taking into account the social perspective – 17.9 thousand rubles for 1 additional year of life. Increase in the life expectancy of 50 year-old patients will be 0.291 year in average. Conclusion. Varenicline therapy of patients with angina pectoris is the economy before cardiac surgery , and after their execution, and this applies not only young, but older patients. The desirability of varenicline including to federal and regional programs to reduce cardiovascular morbidity and mortality is shown.

    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.

    The purpose of this study is to determine the diagnostic accuracy for detection of culprit lesions in patients with unstable angina. Both ATP {sup 201}Tl SPECT and coronary angiography were performed in 51 patients with unstable angina pectoris within a week since the last attack. SPECT images were divided into 17 segments and the regional uptakes were scored semiquantitatively (0=normal to 3=no activity) and compared with the coronary angiographic findings. ATP {sup 201}Tl SPECT revealed decreased uptakes in 54 of 56 culprit lesions. The sensitivity, specificity and accuracy for detection of culprit lesions were 96.4%, 89.5% and 92.4%, respectively. Although adverse effects during ATP administration were complicated in 28 (54.9%) patients, all the complications were mild and resolved within two minutes. ATP {sup 201}Tl SPECT is sensitive and reliable method for detecting culprit lesions and can be performed safely even at acute phase in patients with unstable angina pectoris. (author)

    A 47-year-old woman complained of angina-like chest pain, near-syncope, and syncopal episodes of 17 years' duration. Physical examination was unremarkable. A 12-lead resting ECG showed symmetrically inverted T waves in the inferior and anterolateral leads. A graded treadmill exercise stress test precipitated angina-like chest pain accompanied by a near-syncopal episode associated with a systemic arterial pressure of 60/40 mm Hg. Echocardiography disclosed left ventricular apical obliteration. Left ventriculogram showed a typical "ace of heart'' shadow as well as filling defects and apical obliteration. Endomyocardial biopsy of the left ventricle diagnosed left ventricular endomyocardial fibrosis. Thus, angina-like chest pain and near-syncopal episodes should be added to the list of clinical manifestations of pure left ventricular endomyocardial fibrosis.

    We describe a 77-year-old lady who presented with progressive retrosternal pain radiating to the left arm and the back. After exclusion of cardiac causes a large midoesophageal diverticulum was found on oesophago-gastro-duodenoscopy. Importantly, the retrosternal pain completely disappeared after endoscopic removal of impacted food from the diverticulum. After the surgical resection the patient became fully asymptomatic. This is the first example of angina-like chest pain which definitively resulted from a midoesophageal diverticulum. Therefore, midoesophageal diverticula should be considered as a rare differential diagnosis of exercise-induced retrosternal pain.

    2016-02-01

    The peak sodium current underlies excitability and conduction in heart muscle, but a late sodium current flowing after the peak contributes to maintaining and prolonging the action potential plateau, and also to intracellular sodium loading, which in turn increases intracellular calcium with consequent effects on arrhythmia and diastolic function. Late sodium current is pathologically increased in both genetic and acquired heart disease, making it an attractive target for therapy to treat arrhythmia, heart failure, and angina. This review provides an overview of the underlying bases for the clinical implications of late sodium current block.

    This report describes a case of an unusual association between vasospastic angina, coronary myocardial bridging, and Brugada syndrome. The patient complained of chest pain followed by rhythmic palpitation and syncope. Brugada syndrome ECG markers were documented with transient ST-segment elevation in lateral leads. A coronary angiogram showed a myocardial bridging in the left anterior descending artery and coronary vasospasm was reproduced after intracoronary ergonovine injection in the circumflex coronary artery. Ventricular fibrillation was induced by programmed electrical stimulation. The described association can be important because interaction between ischemia and Brugada syndrome electrophysiological substrate could modulate individual susceptibility to life-threatening ventricular tachyarrhythmias.

    BACKGROUND In the past decades, a large number of randomized controlled trials (RCTs) on the efficacy of ligustrazine injection combined with conventional antianginal drugs for angina pectoris have been reported. However, these RCTs have not been evaluated in accordance with PRISMA systematic review standards. The aim of this study was to evaluate the efficacy of ligustrazine injection as adjunctive therapy for angina pectoris. MATERIAL AND METHODS The databases PubMed, Medline, Cochrane Library, Embase, Sino-Med, Wanfang Databases, Chinese Scientific Journal Database, Google Scholar, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and the Chinese Science Citation Database were searched for published RCTs. Meta-analysis was performed on the primary outcome measures, including the improvements of electrocardiography (ECG) and the reductions in angina symptoms. Sensitivity and subgroup analysis based on the M score (the refined Jadad scores) were also used to evaluate the effect of quality, sample size, and publication year of the included RCTs on the overall effect of ligustrazine injection. RESULTS Eleven RCTs involving 870 patients with angina pectoris were selected in this study. Compared with conventional antianginal drugs alone, ligustrazine injection combined with antianginal drugs significantly increased the efficacy in symptom improvement (odds ratio [OR], 3.59; 95% confidence interval [CI]: 2.39 to 5.40) and in ECG improvement (OR, 3.42; 95% CI: 2.33 to 5.01). Sensitivity and subgroup analysis also confirmed that ligustrazine injection had better effect in the treatment of angina pectoris as adjunctive therapy. CONCLUSIONS The 11 eligible RCTs indicated that ligustrazine injection as adjunctive therapy was more effective than antianginal drugs alone. However, due to the low quality of included RCTs, more rigorously designed RCTs were still needed to verify the effects of ligustrazine injection as adjunctive therapy for

    In patients with severe angina pectoris due to coronary artery disease, who are not candidates for either percutaneous coronary angioplasty or coronary artery bypass surgery, transmyocardial laser revascularization (TMR) often leads to improvement of clinical symptoms and increased exercise capacity. One drawback of TMR is the need for surgical thoracotomy in order to gain access to the epicardial surface of the heart. Therefore, a catheter-based system has been developed, which allows creation of laser channels into the myocardium from the left ventricular cavity.Between January 1997 and November 1999, this "percutaneous myocardial laser-revascularization" (PMR) was performed in 85 patients at the Herzzentrum Leipzig. In 43 patients, only one region of the heart (anterior, lateral, inferior or septal) was treated with PMR; in 42 patients two or three regions were treated in one session. 12.3±4.3 (range 4-22) channels/region were created into the myocardium.Six months after PMR, the majority of patients reported significant improvement of clinical symptoms (CCS class at baseline: 3.3±0.4; after 6 months: 1.6±0.9) (p PMR treated regions.PMR seems to be a safe and feasible new therapeutic option for patients with refractory angina pectoris due to end-stage coronary artery disease. The first results indicate improvement of clinical symptoms and increased exercise capacity; evidence of increased perfusion in the laser-treated regions is still lacking.

    Clinical usefulness of once-daily administration of 20 to 60 mg of efonidipine hydrochloride and coronary hemodynamics during exercise {sup 201}Tl myocardial scintigraphy were investigated in patients with angina pectoris. Out of 11 patients enrolled in this study, 9 patients were included in the evaluation of patients` impression, in improvement rating in subjective symptoms, in the analysis of the exercise test, in the improvement rating of images on {sup 201}Tl myocardial scintigraphy, and in the global improvement rating, while 10 patients were included in the overall safety rating. Four patients in improvement rating in subjective symptoms, 2 in improving rating in the exercise test, and 5 in the global improvement rating were rated `improved` or better. In the improvement rating on the exercise {sup 201}Tl myocardial scintigraphy image, reduction of the image was observed in 5 patients, 3 out of which were evaluated as `improved` or better. A distinctive reduction of ischemic regions was observed in 2 patients out of the 3. A significant decrease in the number of angina pectoris events and a decreasing tendency in consumption of fast-acting nitrates were observed in spite of the low number of the patients studied. An adverse effect was observed in 1 patient and abnormal laboratory values were observed in 2 patients which were improved promptly after withdrawal of the drug. It was in 7 patients evaluated as `no problem`, while in 4 patients it was evaluated as `useful` or more. (author)

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

    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.

A relação entre o hipertireoidismo e as alterações no sistema cardiovascular está bem estabelecida, contudo o hipertireoidismo responde por menos de 5% dos casos de dor torácica. Apresenta-se um caso de uma mulher, 47 anos, com sintomas de precordialgia típica e eletrocardiograma (ECG sugestivo de isquemia coronariana, mas sem alteração laboratorial sugestiva de lesão miocárdica. Anamnese, exame físico e resultados laboratoriais permitiram firmar o diagnóstico de hipertireoidismo. Investigação subseqüente com o cateterismo cardíaco não demonstrou lesões obstrutivas. Após tratamento com iodo radioativo e retorno ao eutireoidismo, a paciente manteve-se assintomática e o ECG e a cintilografia miocárdica foram negativos para isquemia. Esses resultados sugerem uma interação entre hiperatividade tireoidiana e isquemia miocárdica, tendo o hipertireoidismo como provável etiologia dos achados clínicos e eletrocardiográficos.In the presence of angina pectoris in a premenopausal woman without significant risk factors for coronary disease, we have to rule out other causes of coronary lesion of non atherosclerotic origin.

    We studied regional myocardial perfusion by scintigraphic computer-assisted analysis of initial distribution, washout rates, and residual activity of /sup 133/Xe injected into the left coronary artery of four patients with normal arteriograms and 14 patients with coronary stenosis. At rest, residual activity in poststenotic regions was always greater than in control regions, but initial washout rates were not slower. During angina, following xenon injections, the amount of indicator distributed to the poststenotic regions was markedly reduced; the increase of the initial washout rates was smaller than in control regions relative to rest, and residual activity was higher. Initial washout rates did not differ as much as from those of normal myocardium because in severe ischemia too little indicator is deposited initially in these regions to produce a change of any magnitude. Indeed, when angina was induced immediately after the xenon injection, poststenotic washout rates became much slower during angina than at rest, a finding that implicates functional factors in impairing poststenotic myocardial perfusion during angina.

    Objectives To analyze the changes of vasoactive substances originated from endothelium in patients with unstable angina pectoris treated by modified thrombolytic therapy and explore the mechanisms of the drug to treat unstable angina pectoris.Methods 120 patients with unstable angina pectoris who were not well responsed to common medication were studied. Their ECG stress tests were abnormal and there were ischemic changes in Holter. Urokinase 300,000 U was added in 100 ml normal saline and injected within 30 min once a day for 3 days. 300 mg aspirin was administrated a day before and during urokinase applications. Before and after urokinase treatments, endothelin-1, plasma tissue plasminogen activator and its inhibitor-1were determined. Results Compared with pretreatments, after treatments, the activities of tissue plasminogen activator increased, endothelin-1 and the inhibitor-1 decreased. The changes were significant. Conclusions Modified thrombolytic therapy can regulate the vasoactive substances originated endothelium in patients with unstable angina pectoris . The major substances include endothelin-1 ,plasma tissue plasminogen activator and inhibitor-1. This mechanism may suggest that urokinase can treat coronary heart disease effectively.

    OBJECTIVE--To investigate whether plaque rupture and thrombosis have a role in silent ischaemia as well as in unstable angina. DESIGN--Prospective analysis of the results of haemostatic diagnostic tests at the moment of developing silent ischaemia at rest. SETTING--Coronary care unit. PATIENTS--22 patients with acute myocardial infarction, 12 patients with symptomatic angina (unstable angina), and 10 normal volunteers (control group). INTERVENTIONS--Continuous cardiac monitoring detected 15 asymptomatic episodes (silent ischaemia) in 6 patients with unstable angina. Blood samples were obtained at admission and when an asymptomatic alteration was detected and 10 minutes later. MAIN OUTCOME MEASURES--Comparisons of concentrations of tissue plasminogen activator, urokinase type plasminogen activator, tissue plasminogen activator inhibitor-1, cross-linked fibrin degradation products, von Willebrand factor, and thrombin-antithrombin III complexes in patients and controls at admission; same comparisons in patients with silent ischaemia at the start of an episode and 10 minutes later. RESULTS--Tissue plasminogen activator concentrations were raised at admission in patients with acute myocardial infarction (mean (SD) 14.2 (6) ng/ml) and in patients with unstable angina (10.1 (2.5) ng/ml) in comparison with controls (5.1 (2.7) ng/ml, p < 0.01 and < 0.05 respectively). There was no differences between the two groups of patients, however. Similar results were observed at the start of a silent ischaemic episode (9.8 (1.9) ng/ml) and 10 minutes later (10.5 (2.9) ng/ml) compared with controls (p < 0.05). Tissue plasminogen activator inhibitor-1 concentrations were raised in patients with acute myocardial infarction (45.1 (15) ng/ml) compared with volunteers (20.6 (16) ng/ml, p < 0.01). In patients with silent ischaemia tissue plasminogen activator inhibitor-1 concentrations were slightly but not significantly increased. Concentrations of cross-linked fibrin degradation products

    Inherited chromosomally integrated human herpesvirus-6 (iciHHV-6) results in the germ-line transmission of the HHV-6 genome. Every somatic cell of iciHHV-6+ individuals contains the HHV-6 genome integrated in the telomere of chromosomes. Whether having iciHHV-6 predisposes humans to diseases remains undefined. DNA from 19,597 participants between 40 and 69 years of age were analyzed by quantitative PCR (qPCR) for the presence of iciHHV-6. Telomere lengths were determined by qPCR. Medical records, hematological, biochemical, and anthropometric measurements and telomere lengths were compared between iciHHV-6+ and iciHHV-6- subjects. The prevalence of iciHHV-6 was 0.58%. Two-way ANOVA with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on continuous outcomes. Two-way logistic regression with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on disease prevalence. Of 50 diseases monitored, a single one, angina pectoris, is significantly elevated (3.3×) in iciHHV-6+ individuals relative to iciHHV-6- subjects (P = 0.017; 95% CI, 1.73-6.35). When adjusted for potential confounding factors (age, body mass index, percent body fat, and systolic blood pressure), the prevalence of angina remained three times greater in iciHHV-6+ subjects (P = 0.015; 95%CI, 1.23-7.15). Analyses of telomere lengths between iciHHV-6- without angina, iciHHV-6- with angina, and iciHHV-6+ with angina indicate that iciHHV-6+ with angina have shorter telomeres than age-matched iciHHV-6- subjects (P = 0.006). Our study represents, to our knowledge, the first large-scale analysis of disease association with iciHHV-6. Our results are consistent with iciHHV-6 representing a risk factor for the development of angina.

    Addition of Luminol to nondiluted blood of healthy donors results in a short and weak increase of chemiluminescence (CL) from it. Contrary to that in 25 cases of stable angina pectoris the intensity of CL from blood of patients sharply increased upon addition of luminol exceeding that form healthy donors' blood 10-100-fold. 24 hours after the 3D intravenous low-level treatment CL burst in patients' blood in the presence of Luminol was in general significantly lower than before the beginning of the treatment. After the 7th treatment the pattern of CL kinetics was in most cases similar to that of healthy donors' blood. However, after the 10th treatment intensity of Luminol-enhanced CL usually increased and for blood of some patients even exceeded its values obtained before the treatment. Some correlation CL from nondiluted blood with neutrophil activity studied by NTB-test and plasma viscosity of same blood was noted. Using highly sensitive single photon counters it is possible to reveal abnormal levels of CL from no more than 0.1-0.2 ml of blood within 3-5 min.

    Background:Multislice computed tomography (MSCT) coronary angiography (CAG) is a noninvasive technique with a reported high diagnostic accuracy for coronary artery disease (CAD).Women,more frequently than men,are known to develop atypical angina symptoms.The purpose of this study was to investigate whether the diagnostic accuracy of MSCT in women with atypical presentation differs from that in men.Methods:We enrolled 396 in-hospital patients (141 women and 255 men) with suspected or proven CAD who successively underwent both MSCT and invasive CAG.CAD was defined as any coronary stenosis of≥50% on conventional invasive CAG,which was used as the reference standard.The patients were divided into typical and atypical groups based on their symptoms of angina pectoris.The diagnostic accuracy of MSCT,including its sensitivity,specificity,negative predictive value,and positive predictive value (PPV),was calculated to determine the usefulness of MSCT in assessing stenoses.The diagnostic performance of MSCT was also assessed by constructing receiver operating characteristic (ROC) curves.Results:The PPV (91% vs.97%,x2 =5.705,P < 0.05) and diagnostic accuracy (87% vs.93%,x2 =5.093,P < 0.05) of MSCT in detecting CAD were lower in women than in men.Atypical presentation was an independent influencing factor on the diagnostic accuracy of MSCT in women (odds ratio =4.94,95% confidence intervals:1.16-20.92,Walds =4.69,P < 0.05).Compared with those in the atypical group,women with typical angina pectoris had higher PPV (98% vs.74%,x2 =17.283.P < 0.001),diagnostic accuracy (93% vs.72%,x2 =9.571,P < 0.001),and area under the ROC curve (0.91 vs.0.64,Z =2.690,P < 0.01) in MSCT diagnosis.Conclusions:Although MSCT is a reliable diagnostic modality for the exclusion of significant coronary artery stenoses in all patients,gender and atypical symptoms might have some influence on its diagnostic accuracy.

    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.

    To understand the effect of hyperventilation (HV) stress in patients with spastic angina, left ventricular (LV) contraction was analyzed by quantitative phase analysis. The study was performed on 36 patients with spastic angina pectoris, including vasospastic angina pectoris (VspAP: 16 patients) and variant angina pectoris (VAP: 20 patients). First-pass radionuclide ventriculography (first-pass RNV) was performed at rest and after HV stress, and standard deviation of the LV phase distribution (SD) was analyzed. The SD was lower in patients with VspAP than in VAP(12.8{+-}1.4 degrees vs. 14.6{+-}2.2 degrees, p<0.005) at rest. After HV stress, the SD (HVSD) tended to increase in VspAP patients (62.5%), whereas the SD decreased in VAP patients (70%). Due to HV stress, the percentage change in SD (%SD) in VspAP patients was 8.9{+-}23.7% whereas that in VAP patients was -9.1{+-}17.3% (p<0.01). Moreover, phase histograms were divided into HVSD increase and HVSD decrease groups. The HVSD increase group had a decrease of HVEF, but the HVSD decrease group tended to have more decreased HVEF than the HVSD increase group. These results indicate that spastic angina pectoris patients show various responses to HV stress. The HVSD increase group might have additional myocardial ischemia due to regional coronary spasm. In contrast, in the HVSD decrease group severe LV dysfunction or diffuse wall motion abnormality might have been generated, and this caused a reduction in the SD value. Phase analysis would therefore add new information regarding electrocardiographically silent myocardial ischemia due to coronary spasm, and HV stress might increase sensitivity for the detection of abnormalities in quantitative phase analysis, especially in VspAP patients.

    Full Text Available Chronic penile strangulation is exceedingly rare with only 5 cases previously reported. We report an additional case of progressive penile lymphedema due to chronic intermittent strangulation caused by a rubber band applied to the penile base for 6 years. A 49-year-old man presented incapacity to exteriorize the glans penis. For erotic purposes, he had been using a rubber-enlarging band placed in the penile base for 6 years. With chronic use, he noticed that his penis swelled. Physical examination revealed lymphedema of the penis, phimosis and a stricture in the penile base. The patient was submitted to circumcision and the lymphedema remained stable 10 months postoperatively. Chronic penile incarceration usually causes penile lymphedema and urinary disturbance. Treatment consists of removal of foreign devices and surgical treatment of lymphedema.

    Becker myotonia is a recessive muscle disease with prevalence of > 1:50,000. It is caused by markedly reduced function of the chloride channel encoded by CLCN1. We describe a Polish patient with severe myotonia, transient weakness, and muscle cramps who only responds to lidocaine. In addition, the patient has Prinzmetal angina pectoris and multiple lipomatosis. He is compound heterozygeous for a novel p.W303X and a frequent p.R894X CLCN1 mutation. CLCN1 exon number variation was excluded by MLPA. His son with latent myotonia was heterozygeous for p.R894X. We discuss the potential relations of the three rare diseases and the inheritance of p.R894X.

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

    Objective: To elucidate the relationship among pro-inflammatory cytokine (IL-1, IL-6, TNF-a), anti-inflammatory cytokine (IL-10) and MMP-2 and their effects on the stability of plaque in unstable angina. Methods-. The concentrations of IL-1, IL-6, TNF-a, IL-10, MMP-2 and TIMP-2 were analyzed using ELISA in 170 patients and 30 healthy control subjects. Patients were divided into two groups, stable angina (n = 35) and unstable angina (n = 135). Results; The serum levels of IL-1, IL-6, TNF-a, IL-10, MMP-2 and TIMP-2 were significantly higher in UAP group and SAP group compared with the healthy control group ( P < 0. 05 ) , and so were the ratio of MMP-2/TIMP-2 and( IL-1 + IL-6 + TNF-a)/IL-10 (P < 0. 05). The levels of above mentioned cyto-kines and ratios in patients with unstable angina were significantly higher than those with stable angina (P < 0. 05). Correlation analysis revealed the level of MMP-2 was positively related to the levels of IL-1, IL-6, IL-10 and TNF-a. In multiple linear regression analysis, significant positive correlations were found between MMP-2 and IL-10, (IL-1 +IL-6 + TNF-a) /IL-10 and fasting blood glucose separately in patients with unstable angina. Conclusion; The imbalance of proinflammation/anti-inflammation could lead to unstability of the plaque through the regulation of MMP-2, which could trigger unstable angina.%目的:探讨不稳定型心绞痛(UAP)患者血清致炎因子(IL-1、IL-6、TNF-α)、抗炎因子(IL-10)水平与基质金属蛋白酶-2(MMP-2)及其抑制剂(TIMP-2)的关系.方法:选择UAP患者135例(UAP组)、稳定型心绞痛(SAP)患者35例(SAP组)、对照组30例,应用ELISA法检测血清IL-1、IL-6、TNF-α、IL-10、MMP-2、TIMP-2水平.结果:UAP组患者血清IL-1、IL-6、TNF-α、IL-10、(IL-1 +IL-6+TNF-a)/IL-10、MMP-2、TIMP-2、MMP-2/TIMP-2水平高于对照组及SAP组(P均<0.05);Spearson相关分析显示,UAP患者血清MMP-2活性与IL-1、IL-6、IL-10、TNF-α水平正相关(P<0.05);多元

    Objective:To systematically assess the efficacy of the associated prescriptions of Gualou and Xiebai on unstable angina pectoris. Methods:Randomized controlled trials of associated prescriptions of Gualou and Xiebai on unstable angina pectoris were retrieved from the Cochrane library,PubMed,CNKI, Wanfang database and CBM. The risk of bias of included studies was assessed according to the criteria recommended by the Cochrane Handbook for Systematic Reviews of interventions. Such statistical analyses as heterogeneity analysis,meta-analysis,sensitivity analysis and funnel plot analysis were performed using the Review Manager 5.2.6 software. Results:Fourteen qualified trials were included. The risk of bias was generally high and clinical heterogeneity exists among them. Meta-analysis shows that the associated pre scriptions of Gualou and Xiebai can improve angina pectoris(RR=1.24,95%CI[1.18,1.31]) and ECG manifestations(RR=1.29,95%CI[1.19,1.39]),funnel plot is asymmetry. Conclusion:Current evidence indicates that treating un-stable angina pectoris with the associated prescriptions of Gualou and Xiebai can improve the efficacy on unstable angina pectoris. Due to the low quality of included studies ,clinical trials with adequate samples , rational design and strict execution should be carried out to provide more reliable evidence.%目的:系统评价《金匮要略》瓜蒌薤白类方治疗不稳定型心绞痛的临床疗效。方法:检索中国学术文献总库(CNKI)、万方数据库、中国生物医学文献数据库(CBM)、The Cochrane Library、PubMed等数据库,搜集瓜蒌薤白类方治疗不稳定型心绞痛的随机对照试验,按照Cochrane协作网推荐的方法评估纳入研究的偏倚风险,运用RevMan 5.2.6软件完成异质性检验、Meta-分析、敏感性分析、倒漏斗图分析等相关统计分析。结果:共纳入14项合格研究,均存在较高的方法学偏倚风险,Meta-分析显示瓜蒌薤白类方在

    2011-01-01

    In this paper, we introduce stable recursive subhomogeneous algebras (SRSHAs), which is analogous to recursive subhomogeneous algebras (RSHAs) introduced by N. C. Phillips in the studies of free minimal integer actions on compact metric spaces. The difference between the stable version and the none stable version is that the irreducible representations of SRSHAs are infinite dimensional, but the irreducible representations of the RSHAs are finite dimensional. While RSHAs play an important role in the study of free minimal integer actions on compact metric spaces, SRSHAs play an analogous role in the study of free minimal actions by the group of the real numbers on compact metric spaces. In this paper, we show that simple inductive limits of SRSHAs with no dimension growth in which the connecting maps are injective and non-vanishing have topological stable rank one.

    Full Text Available Abstract Background An increasing proportion of Australia's chronic disease burden is carried by the ageing male. The aim of this study was to determine the prevalence of asthma, cancer, diabetes, angina and musculoskeletal conditions and their relationship to behavioural and socio-demographic factors in a cohort of Australian men. Methods Self-reports of disease status were obtained from baseline clinic visits (August 2002 – July 2003 & July 2004 – May 2005 from 1195 randomly selected men, aged 35–80 years and living in the north-west regions of Adelaide. Initially, relative risks were assessed by regression against selected variables for each outcome. Where age-independent associations were observed with the relevant chronic disease, independent variables were fitted to customized multiadjusted models. Results The prevalence of all conditions was moderately higher in comparison to national data for age-matched men. In particular, there was an unusually high rate of men with cancer. Multiadjusted analyses revealed age as a predictor of chronic conditions (type 2 diabetes mellitus, angina, cancer & osteoarthritis. A number of socio-demographic factors, independent of age, were associated with chronic disease, including: low income status (diabetes, separation/divorce (asthma, unemployment (cancer, high waist circumference (diabetes, elevated cholesterol (angina and a family history of obesity (angina. Conclusion Socio-demographic factors interact to determine disease status in this broadly representative group of Australian men. In addition to obesity and a positive personal and family history of disease, men who are socially disadvantaged (low income, unemployed, separated should be specifically targeted by public health initiatives.

    "Archean cratons are relatively flat, stable regions of the crust that have remained undeformed since the Precambrian, forming the ancient cores of the continents" (King, EPSL, 2005). While this type of statement is supported by a wealth of constraints in the case of episodes of thoroughgoing ductile deformation affecting shield regions of Archean and also Peleoproterozoic age, a growing amount of research indicates that shields are not nearly as structurally stable within the broad field of environmental conditions leading to brittle deformation. In fact, old crystalline basements usually present compelling evidence of long brittle deformation histories, often very complex and challenging to unfold. Recent structural and geochronological studies point to a significant mechanical instability of the shield areas, wherein large volumes of 'stable' rocks actually can become saturated with fractures and brittle faults soon after regional cooling exhumes them to below c. 300-350° C. How cold, rigid and therefore strong shields respond to applied stresses remains, however, still poorly investigated and understood. This in turn precludes a better definition of the shallow rheological properties of large, old crystalline blocks. In particular, we do not yet have good constraints on the mechanisms of mechanical reactivation that control the partial (if not total) accommodation of new deformational episodes by preexisting structures, which remains a key to untangle brittle histories lasting several hundred Myr. In our analysis, we use the Svecofennian Shield (SS) as an example of a supposedly 'stable' region with Archean nucleii and Paleoproterozoic cratonic areas to show how it is possible to unravel the details of brittle histories spanning more than 1.5 Gyr. New structural and geochronological results from Finland are integrated with a review of existing data from Sweden to explore how the effects of far-field stresses are partitioned within a shield, which was growing

    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.

    We have previously characterized a novel tyrosine kinase inhibitor peptide (Tkip) that is a mimetic of suppressor of cytokine signaling 1 (SOCS-1) and inhibits JAK2 phosphorylation of the transcription factor STAT1alpha. We show in this study that Tkip protects mice against experimental allergic encephalomyelitis (EAE), an animal model for multiple sclerosis. Mice are immunized with myelin basic protein (MBP) for induction of disease. Tkip (63 mug) administered every other day suppressed the development of acute EAE in 75% of New Zealand White (NZW) mice. Furthermore, Tkip completely protected SJL/J mice, which where induced to get the relapsing/remitting form of EAE, against relapses compared with control groups in which >70% of the mice relapsed after primary incidence of disease. Protection of mice by Tkip was similar to that seen with the type I IFN, IFN-tau. Protection of mice correlated with lower MBP Ab titers in Tkip-treated groups as well as suppression of MBP-induced proliferation of splenocytes taken from EAE-afflicted mice. Cessation of Tkip and IFN-tau administration resulted in SJL/J mice relapsing back into disease. Prolonged treatment of mice with Tkip produced no evidence of cellular toxicity or weight loss. Consistent with its JAK2 inhibitory function, Tkip also inhibited the activity of the inflammatory cytokine TNF-alpha, which uses the STAT1alpha transcription factor. The data presented in this study show that Tkip, like the type I IFN, IFN-tau, inhibits both the autoreactive cellular and humoral responses in EAE and ameliorates both the acute and chronic relapsing/remitting forms of EAE.
