Developed for the treatment of migraine, sumatriptan is an agonist of 5-hydroxytryptamine-1-receptors. Though a pressure sensation is a common complaint, significant ECG changes have not been reported after subcutaneous administration of sumatriptan. A case history is given where angina pectoris...... after sumatriptan self-administration was experienced on two occasions by a 61-year old man with a history of minor myocardial infarction--without post-infarction angina--two years previously. The angina after sumatriptan was accompanied on both occasions by significant ST-segment depression on ECG...

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.

Thallium-201 scintigraphy was performed during the pain free period in 98 patients with unstable angina. Scintiscans were positive in 39 patients, questionable in 27 patients and normal in 32 patients. Eighty-one patients responded favorably to treatment (group I). Seventeen patients had complicated courses (group II) and despite maximal treatment with propranolol either developed infarction (six patients) or continued to have angina necessitating coronary surgery (11 patients). In group I during the pain free period 26 of 81 patients had positive thallium-201 scans, whereas 20 patients had an abnormal ECG at that time; during angina 18 patients had transient ECG changes. In group II during the pain free period 13 of 17 patients had positive scans, whereas two patients had abnormal ECG at that time; during angina 12 patients showed transient ECG changes. The sensitivity to recognize group II was 76% for thallium-201 scintigraphy, 11% for ECG during the pain free period; 70% for ECG during angina; 94% for the combination of either positive scans or abnormal ECG. Thus, positive thallium-201 scans occur in patients with unstable angina, positive scans can be obtained during the pain free period, thallium-201 scans are more frequently positive in patients with complicated course

We evaluated the usefulness of hyperventilation myocardial scintigraphy (HV-SPECT) for diagnosing vasospastic angina pectoris. The subjects consisted of 11 patients with rest angina and 13 with rest and exertional angina in whom coronary spasm was demonstrated by coronary angiography, and 6 with exertional angina in whom a significant stenotic lesion was observed by coronary angiography. Hyperventilation was performed at a rate of 40/min for 5 minutes in all the patients. Ischemia was considered to be present when defect and redistribution were observed by SPECT. HV-SPECT revealed positive findings in 8 patients with rest angina (73%) and 9 with exertional and rest angina (69%) but only in 1 with exertional angina (17%). Ischemic ST changes on monitor ECG were observed in 13 of the 30 patients (43%); ST was enhanced in 4 patients and depressed in 9 patients. In the patients with rest angina, HV-SPECT induced ischemic findings more frequently than exercise SPECT (73% vs 55%). HV-SPECT seems to be useful as a non-invasive method for diagnosing angina pectoris resulting from coronary spasm. (author)

To evaluate the coronary circulation and myocardial perfusion dynamics, we performed left coronary digital subtraction angiography (DSA) in 35 patients with vasospastic angina. The left coronary circulation time (CCT) measured from the proximal left coronary artery to the coronary sinus was 5.77±0.86 sec, and the left epicardial conducting artery transmission time (CAT) measured from the proximal left coronary artery to the apical area was 2.65±0.82 sec in normal controls. The CCT and CAT were significantly prolonged in patients with vasospastic angina, indicating that the coronary peripheral vascular resistance is probably greater after the cessation of nitrates and Ca ++ -antagonists. After the intracoronary injection of ergonovine malate, the CCT was slightly shortened, but the apical T 1/2 was significantly prolonged in patients with vasospastic angina. This suggested that coronary vasospasm is present not only in the epicardial arteries but also in coronary arteries with peripheral resistance. These phenomena were not observed in normal controls. We performed left coronary DSA after conventional left coronary cineangiography. When the CCT exceeded 6.7 sec, we considered that the coronary circulation was significantly impaired. We concluded that the coronary DSA is very useful for evaluating abnormal coronary circulation in patients with vasospastic angina during myocardial perfusion. (author)

2014-01-01

Background Globally, an estimated 54 million people have angina, 16 million of whom are from the WHO South-East Asia region. Despite the increasing burden of cardiovascular disease (CVD) in South Asia, there is no evidence of an economic burden of angina on households in this region. We investigated the economic burden of angina on households in South Asia. Methods We applied a novel propensity score matching approach to assess the economic burden of angina on household out-of-pocket (OOP) health spending, borrowing or selling assets, non-medical consumption expenditure, and employment status of angina-affected individual using nationally representative World Health Survey data from Bangladesh, India, Nepal and Sri Lanka collected during 2002-2003. We used multiple matching methods to match households where the respondent reported symptomatic or diagnosed angina with control households with similar propensity scores. Results Angina-affected households had significantly higher OOP health spending per person in the four weeks preceding the survey than matched controls, in Bangladesh (I$1.94, p = 0.04), in Nepal (I$4.68, p = 0.03) and in Sri Lanka (I$1.99, p angina-affected households relative to matched controls in India (9.60%, p Angina-affected households significantly relied on borrowing or selling assets to finance OOP health expenses in Bangladesh (6%, p = 0.03), India (8.20%, p angina-affected individual remained mostly unaffected. We adjusted our estimates for comorbidities, but limitations on comorbidity data in the WHS mean that our results may be upwardly biased. Conclusions Households that had the respondent reporting angina in South Asia face an economic burden of OOP health expenses (primarily on drugs and other outpatient expenses), and tend to rely on borrowing or selling assets. Our analysis underscores the need to protect South Asian households from the financial burden of CVD. PMID:24548585

Patients with unstable angina fall into a wide prognostic and therapeutic spectrum but, in general, have great access to specialty care and invasive procedures. In the modern era, in which admissions for unstable angina outnumber those for myocardial infarction, and growing economic pressures are placed on health care systems, cardiologists must re-examine clinical strategies for treating unstable angina in the light of health-cost accounting. The aims of the present study were to examine the current management of patients admitted to our cardiology department and to calculate the medical costs. A patient schedule was drawn up to prospectively register the number and type of cardiac processes carried out during hospitalization for all unstable angina patients in the period between March 1st and May 30th, 1995. Time (minutes) actually spent by both physicians and nurses for each cardiac process were carefully recorded in order to calculate the activity budget. The effective economic budget was built for each cardiac process taking into account salaries, consumable supplies, equipment service contracts, depreciation and indirect medical and non medical costs for CCU and ward. Based to the Diagnosis Related Groups (DRG) system, 53 out of 318 patients (16%) were admitted with documented or suspected unstable angina and allocated to discharge into four DRGs: DRG 140-medically treated unstable angina: 18 patients; DRG 124-unstable angina with angiography: 16 patients; DRG 122-unstable angina evolving in myocardial infarction: 6 patients; DRG 112-unstable angina with angioplasty: 13 patients. The mean cost for hospitalized patient with unstable angina was 5,574,958 Italian Liras (DRG 140 = 2,687,719; DRG 124 = 2,800,347; DRG 122 = 6,086,563; DRG 112 = 12,751,454). The difference in costs was essentially related to the procedures involved in medical care, DRGs with expensive cardiac processes having higher costs. Furthermore, these data show a deep discrepancy between

Ranolazine sustained-release tablets were recently approved in the EU for chronic stable angina as add-on therapy when symptoms are not controlled with first-line agents. The mechanism of action is thought to involve inhibition of late sodium influx in the heart, which can reduce abnormalities...... of contractility and repolarisation associated with ischaemia. Ranolazine increases the exercise capacity, reduces angina, and diminishes the use of nitroglycerine. The drug has an excellent safety profile and may be a valuable addition to the treatment of chronic stable angina....

Current therapy for stable angina includes surgical and percutaneous revascularization, which has been improved tremendously over the last decades. Smoking cessation and regular exercise are the cornerstone for prevention of further cerebrovascular events. Medical treatment includes treatment of cardiovascular risk factors and antithrombotic management, which can be a challenge in some patients. Owing to the fact the coronary revascularization is readily accessible these days in many industrialized countries, the importance of antianginal therapy has decreased over the past years. This article presents a contemporary overview of the management of patients with stable angina in the year 2015.

Myocardial radiocardiography and scintigraphy with 99m Tc-pyrophosphate was performed in 58 patients with stable angina and 60 patients with unstable angina. In patients with stable angina, positive scintigrams were mostly recorded after anginal attacks. Their central hemodynamic parameters deteriorated progressively as angina increased in severity. Patients with unstable angina typically showed myocardial accumulation of the label that was unrelated to anginal attacks and recordable by direct-projection scintigraphy. The assessment of myocardial radiocardiographic and scintigraphic data allows one to differentiate between stable and unstable angina

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.

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. Copyright © 2016 Elsevier Inc. All rights reserved.

Abdominal angina

Abdominal angina due to occlusive disease of the mesenteric arteries has been the to become clinically manifest only in the presence of severe disease in at least two of the following vessels: celiac, SMA, and IMA. Still, many patients who gradually develop significant two-vessel disease have few or no associated symptoms. Differences in collateral circulation and in cardiac index account for some of the clinical variation. The usual clinical manifestations include severe post-prandial pain, sitophobia (fear of eating because of the anticipated symptoms), and profound weight loss. Uncommonly, diarrhea, nausea, or vomiting may be encountered. Smoking is a common historical feature. Most series document a female predilection. Aside from occasional abdominal bruits and (more commonly) findings of peripheral vascular occlusive disease, the physical exam discloses only cachexia. But the differential diagnosis of profound weight loss is extensive. Therefore, abdominal angina has always created a diagnostic challenge. Multiple imaging modalities are often employed, and a seemingly negative evaluation often culminates in biplane aortography. The latter typically reveals stenoses and/or occlusions in at least two of the three mesenteric arteries. The authors discuss how a variety of surgical treatments, including thromboendarterectomy and bypass grafting, have evolved. Recently reported results have been excellent

The purpose of this systematic review is to assess the effectiveness of acupuncture for angina pectoris. Eleven electronic databases were searched until January 2013. The study included randomized controlled trials that the effectiveness of acupuncture alone was compared to anti-angina medicines (in addition to conventional treatment) and the effectiveness of a combination of acupuncture plus anti-angina medicines was compared to anti-angina medicines alone. The trial selection, data extraction, quality assessment and data analytic procedures outlined in the 2011 Cochrane Handbook were involved. The study included 25 randomized controlled trials (involving 2,058 patients) that met our inclusion criteria. The pooled results showed that the number of patients with ineffectiveness of angina relief was less in the combined acupuncture-anti-angina treatment group than in the anti-angina medicines alone group (RR 0.33, 95% CI 0.23-0.47, p angina medicines alone group, fewer patients in the combined treatment group showed no ECG improvement (RR 0.50, 95% CI 0.40-0.62, p angina medicines alone for both outcome measures. Only four trials mentioned adverse effects. One trial found no significant difference between acupuncture and Chinese medicine, and three reported no adverse events. The quality of the trials was found to be low. The findings showed very low evidence to support the use of acupuncture for improving angina symptoms and ECG of angina patients. However, the quality of the trials included in this study was low. Large and rigorously designed trials are needed to confirm the potential benefit and adverse events of acupuncture.

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.

Previous studies suggest that among patients with stable coronary artery disease, patients with diabetes mellitus (DM) have less angina and more silent ischemia when compared with those without DM. However, the burden of angina in diabetic versus nondiabetic patients after elective percutaneous coronary intervention (PCI) has not been recently examined. In a 10-site US PCI registry, we assessed angina before and at 1, 6, and 12 months after elective PCI with the Seattle Angina Questionnaire angina frequency score (range, 0-100, higher=better). We also examined the rates of antianginal medication prescriptions at discharge. A multivariable, repeated-measures Poisson model was used to examine the independent association of DM with angina over the year after treatment. Among 1080 elective PCI patients (mean age, 65 years; 74.7% men), 34.0% had DM. At baseline and at each follow-up, patients with DM had similar angina prevalence and severity as those without DM. Patients with DM were more commonly prescribed calcium channel blockers and long-acting nitrates at discharge (DM versus not: 27.9% versus 20.9% [ P =0.01] and 32.8% versus 25.5% [ P =0.01], respectively), whereas β-blockers and ranolazine were prescribed at similar rates. In the multivariable, repeated-measures model, the risk of angina was similar over the year after PCI in patients with versus without DM (relative risk, 1.04; range, 0.80-1.36). Patients with stable coronary artery disease and DM exhibit a burden of angina that is at least as high as those without DM despite more antianginal prescriptions at discharge. These findings contradict the conventional teachings that patients with DM experience less angina because of silent ischemia. © 2017 American Heart Association, Inc.

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

Amenorrea primaria

Full Text Available

La amenorrea o ausencia de menstruación es una causa común de consulta. La mayoría de los casos están representados por causas fisiológicas tales como embarazo y lactancia, estados prepuberales y menopausia, o por los de amenorrea secundaria en quienes la regla se ha presentado antes, pero que desaparece por un período determinado de tiempo, considerado con criterio estricto por algunos como de seis meses para mujeres con ciclos regulares o de doce para aquellas con ciclos irregulares.

La amenorrea primaria es una situación menos común y se define como la ausencia de menarquía a los 18 años, aunque este diagnóstico podría entrar a considerarse en pacientes de 16 años o más con menarquía retrasada en quienes otros signos de pubertad que suelen aparecer previamente – tales como pubarquia, telarquia y adrenarquia- no se observan. La división de amenorrea en primaria y secundaria es algo artificial, ya que algunos pacientes con trastornos que usualmente se asocian a amenorrea primaria, logran menstruar espontáneamente algunas veces.

La historia y el examen físico son muy importantes para un diagnóstico inicial, ya que en algunas ocasiones el mismo problema existe en otras hermanas o se observa un fenotipo característico como en el Síndrome de Turne:- o en el de los testículos feminizantes; la asociación de signos de hiperandrogenismo nos haría pensar en una hiperplasia suprarrenal congénita o en tumores suprarrenales u ováricos con elevada producción de andrógenos; el infantilismo sexual, en causas hipotalámicas o hipofisiarias, si además hay corta estatura sin otras alteraciones fenotípicas; un fenotipo femenino puberal normal sin genitales internos y palpables nos haría pensar en una agenesia uterina, mientras que una queja de dolor abdominal cíclico con distensión pélvica sugiere un himen imperforado que se comprueba al examen pélvico.

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

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

Angina in patients with coronary artery disease is associated with worse quality of life; however, the relationship between angina frequency and resource utilization is unknown. Using data from the MERLIN-TIMI 36 trial, we assessed the association between the extent of angina after an acute coronary syndrome (ACS) and subsequent cardiovascular resource utilization among 5460 stable outpatients who completed the Seattle Angina Questionnaire at 4 months after an ACS and who were then followed for an additional 8 months. Angina frequency was categorized as none (score, 100; 2739 patients), monthly (score, 61 to 99; 1608 patients), weekly (score, 31 to 60; 854 patients), and daily (score, 0 to 30; 259 patients). Multivariable regression models evaluated the association between angina frequency and overall costs attributable to cardiovascular hospitalizations, outpatient visits and procedures, and medications. As compared with no angina, overall costs increased in a graded fashion with higher angina frequency-no angina, $2928 (reference); monthly angina, $3909 (adjusted relative cost ratio, 1.29; 95% CI, 1.21 to 1.39); weekly angina, $4558 (adjusted relative cost ratio, 1.52; 95% CI, 1.48 to 1.67); and daily angina, $6949 (adjusted relative cost ratio, 2.32; 95% CI, 2.01 to 2.69; P for trend 2-fold increase in resource utilization and incremental costs of $4000 after 8 months of follow-up.

Tc-99m pyrophosphate (PYP) and Tl-201 simultaneous dual energy single photon emission computed tomography (SPECT) were performed in 33 patients with clinically unstable angina. According to the presence or absence of PYP accumulation in the myocardium, the patients were classified as PYP (+) group (n=22) and PYP (-) group (n=11). Clinical features, types of unstable angina, ECG changes, and serial creatine kinase (CK) data were compared in the two groups. The 'new angina at rest' type of unstable angina was more significantly common in the PYP (+) group (16/22) than the PYP (-) group (2/11). The remaining 6 patients in the PYP (+) group and 2 patients in the PYP (-) group had 'angina of effort with changing pattern'. There was a significant difference in the occurrence of ST elevation and ST depression between the group: 59% in the PYP (+) group vs. 18% in the PYP (-) group for ST elevation and 23% in the PYP (+) group vs. 64% in the PYP (-) group for ST depression. The PYP (+) group showed significant improvement in ejection fraction in the stable state (57±12%) as compared with the unstable state (62±11%), although there was no difference between the stable and unstable state in the PYP (-) group. Although wall motion abnormality index (WMI) was poorer in the PYP (+) group than the PYP (-) group, it improved to the same degree as the PYP (-) group one month later. These data suggest that the area showing PYP (+) may reflect stunned myocardium and that Tc-99m PYP accumulation may correlate with clinical features of unstable angina. (N.K.)

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

The incidence of ischemic heart disease is higher in patients with HIV/AIDS. However, the frequency of angina pectoris in these patients is still not known. Literature about this subject is still scarce. To evaluate the prevalence of angina pectoris and risk factors for coronary disease and to examine the association between traditional risk factors and HIV-related risk factors and angina pectoris. An epidemiological cross-sectional study, analyzed as case-control study, involving 584 patients with HIV/AIDS. Angina pectoris was identified by Rose questionnaire, classified as definite or possible. Information regarding risk factors was obtained through a questionnaire, biochemical laboratory tests, medical records and anthropometric measures taken during consultations at AIDS treatment clinics in Pernambuco, Brazil, from June 2007 to February 2008. To adjust the effect of each factor in relation to others, multiple logistic regression was used. There was a preponderance of men (63.2%); mean ages were 39.8 years for men, 36.8 years for women. The prevalence of definite and possible angina were 11% and 9.4%, respectively, totaling 20.4%, with independent associations between angina and smoking (OR = 2.88; 95% CI: 1.69-4.90), obesity (OR = 1.62; 95% CI: 0.97-2.70), family history of heart attack (OR = 1.70; 95% CI: 1.00-2.88), low schooling (OR = 2.11; 95% CI: 1.24-3.59), and low monthly income (OR = 2.93; 95% CI: 1.18-7.22), even after adjustment for age. This study suggests that angina pectoris is underdiagnosed, even in patients with medical monitoring, revealing lost opportunities in identification and prevention of cardiovascular morbidity.

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

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.

We evaluated the clinical significance of myocardial imaging using 123 I-15-(p-iodophenyl)-3-methyl pentadecanoic acid (BMIPP) scintigraphy in patients with stable effort angina pectoris (SAP) and unstable angina pectoris (UAP). Thirty-three patients with SAP were studied using rest BMIPP and stress 201 TlCl (Tl) myocardial scintigraphy, and 13 patients with worsening effort type of UAP were also examined using both rest BMIPP and Tl scintigraphy. We compared those BMIPP findings with myocardial perfusion images obtained with Tl and the regional wall motion determined by left ventriculography. In 45% of 282 segments of myocardial ischemia of SAP, the degree of myocardial uptake of BMIPP was concordant with that of stress Tl and the defect score of Tl was higher than that of BMIPP. On the other hand, in 32% of 62 segments of ischemia of UAP, the degree of myocardial BMIPP and Tl uptake was concordant and BMIPP defect score was higher than Tl score. In SAP, the decrease in regional wall motion agreed better with the decrease in myocardial uptake of BMIPP than that of Tl. These results suggest that myocardial ischemic regions decreased BMIPP uptake show the disturbance of fatty acid metabolism and lead to abnormal wall motions. Such ischemic regions may be clinically severe state in patients with angina pectoris. (author)

In chronic stable angina, elevated heart rate contributes to the development of symptoms and signs of myocardial ischaemia by increasing myocardial oxygen demand and reducing diastolic perfusion time. Accordingly, heart rate reduction is a well-known strategy for improving both symptoms of myocardial ischaemia and quality of life (QOL). The heart rate-reducing agent ivabradine, a direct and selective inhibitor of the I f current, decreases myocardial oxygen consumption while increasing diastolic time, without affecting myocardial contractility or coronary vasomotor tone. Ivabradine is indicated for treatment of stable angina and chronic heart failure (HF). This review examines available evidence regarding the efficacy and safety of ivabradine in stable angina, when used as monotherapy or in combination with beta-blockers, in particular angina subgroups and in patients with stable angina with left ventricular systolic dysfunction (LVSD) or HF. Trials involving more than 45 000 patients receiving treatment with ivabradine have shown that this agent has antianginal and anti-ischaemic effects, regardless of age, sex, severity of angina, revascularisation status or comorbidities. This heart rate-lowering agent might also improve prognosis, reduce hospitalisation rates and improve QOL in angina patients with chronic HF and LVSD. PMID:29632676

In the absence of a previous global comparison, we examined the variability in the prevalence of angina across 52 countries and its association with body weight and the poverty index using data from the World Health Organization-World Health Survey. The participants with angina were defined as those who had positive results using a Rose angina questionnaire and/or self-report of a physician diagnosis of angina. The body mass index (BMI) was determined as the weight in kilograms divided by the square of the height in meters. The poverty index (a standard score of socioeconomic status for a given country) was extracted from the United Nations' statistics. The associations of angina with the BMI and poverty index were analyzed cross-sectionally using univariate and multivariate analyses. The results showed that the total participants (n = 210,787) had an average age of 40.64 years. The prevalence of angina ranged from 2.44% in Tunisia to 23.89% in Chad. Those participants with a BMI of poverty status was considered. A tendency was seen for underweight status and a poverty index >14.65% to be associated with the risk of having angina, although these associations were not statistically significant in the multilevel models. In conclusion, significant variations were found in the anginal rates across 52 countries worldwide. An increased BMI was significantly associated with the odds of having angina.

/sup 99m/Technetium stannous pyrophosphate has been shown to accumulate in acutely infarcted myocardium. To determine if the isotope is also taken up by severely ischemic, but not necrotic myocardium, we performed myocardial scintigraphic studies in 17 patients with chest pains. Seven of the patients satisfied conventional clinical, electrocardiographic, and laboratory criteria for the diagnosis of unstable angina and showed no electrocardiographic or enzymatic evidence of myocardial necrosis. Five of these seven patients with unstable angina demonstrated abnormal localized patterns, and one showed a borderline picture. Myocardial scintiscans were normal in all of a control group of ten patients with stable angina. Thus, scanning with /sup 99m/technetium stannous pyrophosphate is shown to be of value in the objective demonstration of myocardial abnormality in unstable angina

There is a group of patients with chronic refractory chest angina, who are not ideal candidates for surgical or percutaneous revascularization and who although having a good medical handling continues to experience severe episodes of angina. The spinal electrical stimulator is a neuromodulators used as an alternative to treat these patients. The objective is to realize a review of scientific literature regarding the spinal electric stimulation in the treatment of chest angina, its mechanism of action, benefits and its cost effectiveness. Materials and methods: using the Cochrane methodology, a search of articles published from January 1980 to January 2007 in Medline using the terms spinal cord stimulation, was realized. The papers considered most pertinent were selected. Conclusions: the anti-ischemic effect of the electrical spinal stimulator reduces the episodes of chest angina, improves the quality of life and the tolerance to exercise, diminishes the hospital stay and delays the appearance of ischemic signs

Myocardial ischemia and angina pectoris

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

Samim, Arang; Nugent, Lynn; Mehta, Puja K.; Shufelt, Chrisandra; Merz, C. Noel Bairey

2014-01-01

Opinion statement Microvascular coronary dysfunction (MCD) is an increasingly recognized cause of cardiac ischemia and angina, more commonly diagnosed in women. Patients with MCD present with the triad of persistent chest pain, ischemic changes on stress testing, and no obstructive coronary artery disease (CAD) on cardiac catheterization. Data from National Heart, Lung and Blood Institute (NHLBI)-sponsored Women’s Ischemia Syndrome Evaluation (WISE) study has shown that the diagnosis of MCD is not benign, with a 2.5% annual risk of adverse cardiac events including myocardial infarction, stroke, congestive heart failure, or death. The gold standard diagnostic test for MCD is an invasive coronary reactivity test (CRT), which uses acetylcholine, adenosine, and nitroglycerin to test the endothelial dependent and independent, microvascular and macrovascular coronary function. The CRT allows for diagnostic and treatment options as well as further risk stratifying patients for future cardiovascular events. Treatment of angina and MCD should be aimed at ischemia disease management to reduce risk of adverse cardiac events, ameliorating symptoms to improve quality of life, and to decrease the morbidity from unnecessary and repeated cardiac catheterization in patients with open coronary arteries. A comprehensive treatment approach aimed at risk factor managment, including lifestyle counseling regarding smoking cessation, nutrition and physical activity should be initiated. Current pharmacotherapy for MCD can include the treatment of microvascular endothelial dysfunction (statins, angiotensin-converting enzyme inhibitor, low dose aspirin), as well as treatment for angina and myocardial ischemia (beta blockers, calcium channel blockers, nitrates, ranolazine). Additional symptom management techniques can include tri-cyclic medication, enhanced external counterpulsation, autogenic training, and spinal cord stimulation. While our current therapies are effective in the treatment

Sexual function in patients with chronic angina pectoris.

Kloner, Robert A; Henderson, Luana

2013-06-01

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.

Chronic stable angina is associated with lower health-related quality of life: evidence from Chinese patients.

Directory of Open Access Journals (Sweden)

Jing Wu

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

Update on ranolazine in the management of angina

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

Due to sensorial autonomic neuropathy, the type and severity of angina pectoris in patients with diabetes mellitus (DM) may be rather different from the type and severity of angina pectoris in patients without DM. The aim of the study was to understand if angina pectoris is related to extensive coronary artery disease (CAD) in patients with DM. The study included 530 patients with DM who underwent coronary angiography at our center in 2009 and 2010. Patients were divided into 4 groups according to type of chest pain: group 1, noncardiac chest pain or no pain; group 2, angina equivalent; group 3, atypical angina; and group 4, typical angina. All angiograms were re-evaluated and Gensini scores were calculated. Three-vessel disease was diagnosed in the presence of stenosis >50% in all 3 coronary artery systems. There were no statistically significant differences between the groups with regard to age, sex, systolic or diastolic blood pressures, body mass index, creatinine clearance, or lipid profile. Fasting blood glucose was significantly higher in group 4 than in group 2. Gensini scores were not statistically different between groups 1 and 2 or between groups 3 and 4; however, the scores for groups 3 and 4 were higher than the score for either group 1 or group 2. Prevalence of 3-vessel disease was significantly higher in groups 3 and 4 compared with the other groups. The presence of angina pectoris was related to extensive CAD in patients with DM. The extent of CAD was not correlated with the type of angina (typical or atypical). © 2013 Wiley Periodicals, Inc.

Evaluation of coronary hemodynamics and exercise 201Tl-myocardial scintigraphy in patients with vasospastic angina

International Nuclear Information System (INIS)

Matsumura, Kentaro; Nakase, Emiko; Haiyama, Tohru; Hasegawa, Akira; Saito, Takayuki

1992-01-01

To clarify the coronary hemodynamics and myocardial perfusion in patients with vasospastic angina, we performed exercise 201 Tl-myocardial scintigraphy (planar and SPECT) in 72 patients and left coronary digital subtraction angiography (DSA) in 37 patients without significant organic coronary artery stenosis. Coronary artery spasm was documented by coronary angiography in all patients. Fifty-four patients (75%) developed exercise-induced 201 Tl-myocardial perfusion defect on SPECT. 201 Tl pulmonary uptake (L/H) was significantly increased in patients with vasospastic angina. Especially, L/H was higher in patients with multiple small perfusion defect on 201 Tl-SPECT, so that exercise-induced left ventricular dysfunction existed in patients with vasospastic angina and especially in cases of multiple small perfusion defect on 201 Tl-SPECT. The left coronary circulation time (CCT) was prolonged in patients with vasospastic angina. The mechanism of prolonged CCT is still unknown, but we suspected that prolonged CCT was induced by increased peripheral coronary vascular resistance in patients with vasospastic angina. It was concluded that the peripheral coronary circulation was disturbed in patients with vasospastic angina, but its abnormal coronary circulation had no relation to location of spasm-induced vessels. We concluded that impaired coronary microcirculation was taken a part of pathophysiology in vasospastic angina. (author)

Angina pectoris refractory for conventional therapy--is neurostimulation a possible alternative treatment?

Science.gov (United States)

Hautvast, R W; DeJongste, M J; ter Horst, G J; Blanksma, P K; Lie, K I

1996-07-01

The treatment of angina pectoris as a symptom of coronary artery disease usually is focused on restoring the balance between oxygen demand and supply of the myocardium by administration of drugs interfering in heart rate, cardiac pre- and afterload, and coronary vascular tone. For nonresponders to drug therapy or for those with jeopardized myocardium, revascularization procedures such as coronary bypass surgery and percutaneous transluminal coronary angioplasty are at hand. However, the atherosclerotic process is not stopped by these therapies and, at longer terms, angina may recur. It is not always possible to revascularize all the patients who do not positively react to medical treatment. Those with angina, not responding to adequate medication and who are not suitable anymore for revascularization, are considered to suffer from refractory angina pectoris. This group of patients has a poor quality of life, for their exercise tolerance is severely afflicted. For these patients, neurostimulation has been described repeatedly as an effective and safe therapy. The mechanism of action of neurostimulation is not completely known, but recent studies suggest an anti-ischemic effect, exerted through changes in myocardial blood flow. As soon as its safety is sufficiently established, it may become a useful alternative in the treatment of refractory angina pectoris.

Beneficial effect of nitrates on myocardial glucose utilization in unstable angina pectoris

Araujo, L.I.; Camici, P.; Spinks, T.; Jones, T.; Maseri, A.

1987-01-01

Myocardial uptake of the glucose analog F-18-2-fluoro-2-deoxy-D-glucose (FDG) was assessed by positron emission tomography in 6 normal volunteers, 7 patients with chronic stable angina and 22 patients with unstable angina at rest in fasting conditions. Regional myocardial perfusion was assessed by rubidium-82. The study was repeated a few days later after intravenous infusion of isosorbide dinitrate. FDG uptake was similar in control subjects and patients with stable angina (0.023 +/- 0.032 vs 0.012 +/- 0.008 mol/ml/min, p less than 0.42) but was about 4-fold higher on the average in patients with unstable angina (0.084 +/- 0.047, p less than 0.01). The severity of coronary obstructions in stable and unstable angina patients was similar. The increased uptake involved the whole heart, including areas not distal to critically stenosed vessels; it was not associated with reduced myocardial perfusion and was not related to a recent episode of transient ischemia as assessed by symptoms and by Holter monitoring. After continuous infusion of nitrates, FDG uptake was consistently and significantly reduced toward normal levels both in areas perfused by critically stenosed coronary arteries and by noncritically stenosed vessels

To evaluate the efficacy and safety of Ginkgo Biloba extract for patients with angina pectoris according to the available evidence. Electronic databases were searched for all of the randomized controlled trials (RCTs) of angina pectoris treatments with Ginkgo Biloba extract, either alone or combined with routine Western medicine (RWM), and controlled by untreated, placebo, Chinese patent medicine, or RWM treatment. The RCTs were retrieved from the following electronic databases: PubMed/MEDLINE, ProQuest Health and Medical Complete, Springer, Elsevier, and ProQuest Dissertations and Theses, Wanfang Data, China National Knowledge Infrastructure (CNKI), VIP database, China Biology Medicine (CBM), Chinese Medical Citation Index (CMCI), from the earliest database records to December 2012. No language restriction was applied. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. RevMan 5.1.0 provided by Cochrane Collaboration The data were analysed by using. A total of 23 RCTs (involving 2,529 patients) were included and the methodological quality was evaluated as generally low. Ginkgo Biloba extract with RWM was more effective in angina relief and electrocardiogram improvement than RWM alone. Reported adverse events included epigastric discomfort, nausea, gastrointestinal reaction, and bitter taste. Ginkgo Biloba extract may have beneficial effects on patients with angina pectoris, although the low quality of existing trials makes it difficult to draw a satisfactory conclusion. More rigorous, high quality clinical trials are needed to provide conclusive evidence.

Double hazards of ischemia and reperfusion arrhythmias in a patient with variant angina pectoris.

Science.gov (United States)

Xu, Mingzhu; Yang, Xiangjun

2015-01-01

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. Copyright © 2015 Elsevier Inc.

Kronenberg, M.W.; Robertson, R.M.; Born, M.L.; Steckley, R.A.; Robertson, D.; Friesinger, G.C.

1982-01-01

Myocardial thallium scintigraphy was performed in four subjects with variant angina and in one subject with isolated, fixed coronary obstruction. Three subjects with variant angina had short episodes of ischemic ST-segment elevation that lasted 20--100 seconds. Thallium scintigrams demonstrated excess uptake in regions judged to be ischemic by angiographic and electrocardiographic criteria. Two subjects, one with variant angina and the other with a fixed coronary lesion, had prolonged episodes of ischemia that lasted 390--900 seconds. Both had reduced thallium uptake in the ischemic regions. We conclude that myocardial reactive hyperemia is the cause of excess thallium uptake in patients with variant angina who have short episodes of myocardial ischemia

Technetium-99m-pyrophosphate myocardial imaging in unstable angina

The authors have found that approximately one third of patients with the syndrome of unstable angina pectoris have abnormal 99mTc-pyrophosphate myocardial scintigrams even in the absence of abnormal enzymes and electrocardiographic confirmation of the presence of acute myocardial necrosis. Thus, 99mTc-pyrophosphate myocardial imaging technique appears to represent a sensitive means to detect acute multicellular injury associated with the clinical syndrome of unstable angina pectoris even when cardiac enzymes are normal and the electrocardiogram does not definitively document the presence of acute myocardial necrosis.

2016-01-01

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.

Race and sex disparities in in-hospital treatment and outcomes of patients with acute myocardial infarction (MI) have been described, but little is known about race and sex differences in post-MI angina and long-term risk of unplanned rehospitalization. We examined race and sex differences in post-MI angina frequency and 1-year unplanned rehospitalization to identify factors associated with unplanned rehospitalization, testing for whether race and sex modify these relationships. Using TRANSLATE-ACS (Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events after Acute Coronary Syndrome) data, we examined 6-week and 1-year angina frequency and 1-year unplanned rehospitalization stratified by race and sex among MI patients treated with percutaneous coronary intervention. We used multivariable logistic regression to assess factors associated with unplanned rehospitalization and tested for interactions among angina frequency, race, and sex. A total of 11 595 MI patients survived to 1 year postdischarge; there were 66.6% white male patients, 24.3% white female patients, 5.3% black male patients, and 3.8% black female patients. Overall, 29.7% had angina at 6 weeks, and 20.6% had angina at 1 year postdischarge. Relative to white patients, black patients were more likely to have angina at 6 weeks (female: 44.2% versus 31.8%; male: 33.5% versus 27.1%; both Prace or sex (adjusted 3-way P interaction =0.41). One-fifth of MI patients treated with percutaneous coronary intervention report 1-year postdischarge angina, with black and female patients more likely to have angina and to be rehospitalized. Better treatment of post-MI angina may improve patient quality of life and quality of care and help to lower rates of rehospitalization overall and particularly among black and female patients, given their high prevalence of post-MI angina.

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

The role of magnetic resonance imaging in characterizing normal, ischemic and infarcted segments of myocardium was examined in 8 patients with unstable angina, 11 patients with acute myocardial infarction, and 7 patients with stable angina. Eleven normal volunteers were imaged for comparison. Myocardial segments in short axis magnetic resonance images were classified as normal or abnormal on the basis of perfusion changes observed in thallium-201 images in 22 patients and according to the electrocariographic localization of infarction in 4 patients. T2 relaxation time was measured in 57 myocardial segments with abnormal perfusion (24 with reversible and 33 with irreversible perfusion changes) and in 25 normally perfused segments. T2 measurements in normally perfused segments of patients with acute myocardial infarction, unstable angina and stable angina were within normal range derived from T2 measurements in 48 myocardial segments of 11 normal volunteers (42 +/- 10 ms). T2 in abnormal myocardial segments of patients with stable angina also was not significantly different from normal. T2 of abnormal segments in patients with unstable angina (64 +/- 14 in reversibly ischemic and 67 +/- 21 in the irreversibly ischemic segments) was prolonged when compared to normal (p less than 0.0001) and was not significantly different from T2 in abnormal segments of patients with acute myocardial infarction (62 +/- 18 for reversibly and 66 +/- 11 for irreversibly ischemic segments). The data indicate that T2 prolongation is not specific for acute myocardial infarction and may be observed in abnormally perfused segments of patients with unstable angina

To determine whether unstable angina is co-related to seropositivity to chronic Helicobacter pylori (HP) infection. It is a case control, descriptive study conducted at CCU in Razi Hospital in Ahwaz a city southwest Iran, from 2004 to 2005. We measured serum HP- lgG levels of participants in CCU in a hospital. Blood samples were drawn during study period from 96 patients (mean age 56 years) with Unstable Angina (UA) according to American Heart Association criteria and from 96 participants free of cardiovascular disease (mean age 58 years) and stored at 20 degree C. Serology results were studied in relation to UA. Using chi squared test, odds ratios (OR) and 95% confidence intervals (CI) were calculated, adjusting for age, gender, and established risk factors. Seventy nine (82.3%) of patients with unstable angina and 55(61.1%) in the control group presented a positive anti HP-lgG. Odds ratio was 3 with 95% CI: 1.9 to 4.3. There was significant relation between HP-lgG positivity and unstable angina (P 0.05). Our study revealed relationship between seropositivity of HP-lgG and unstable angina. (author)

To assess validity of adjuvant use of pumpan, a homeopathic compound, in patients with unstable angina pectoris and angina of effort (functional class III-IV) receiving conventional treatment. A direct open controlled trial for 15 months performed initially in hospital, then outpatiently, covered 49 patients with severe angina. Examination of the patients included evaluation of clinical condition and the disease course, lipid metabolism, hemostasis, blood plasma electrolytes, aminotransferases, echo-CG, bicycle exercise, rheoencephalography, ultrasonic dopplerography of head and neck vessels. Pumpan produced a positive effect total nonspecific systemic resistance improved, number of hospitalizations reduced, intracardiac hemodynamics improved in some cases with severe angina. Homeopathic compound pumpan can be recommended in the treatment of severe angina to reinforce antianginal effect, improve the disease clinical course, to obtain a hypocoagulative and hypocholesterolemic effect, to normalize intracardiac hemodynamics, to raise myocardial performance and intracoronary reserve as well as nonspecific resistance of the body.

Unstable angina represents a heterogeneous spectrum of clinical entities between chronic stable angina and acute myocardial infraction. Acute ischemic syndromes (including unstable angina) result from abrupt reduction in coronary flow, frequently after atherosclerotic plaque disruption and with or without associated thrombosis or vasospasm. Nuclear cardiology studies and in particular, myocardial perfusion imaging are powerful noninvasive tools for detecting and assessing the severity of acute ischemic syndromes, including unstable angina pec tories. The information derived from a nuclear cardiology study can answer unresolved clinical question and aid in subsequent patient management, specifically jeopardized myocardium detected during spontaneously occurring acute chest pain or controlled stress testing are important determinant of: 1) The need for admission to an intensive care monitoring unit 2) The need for and urgency of coronary angiography 3) The appropriate use of percutaneous or surgical coronary revascularization procedures. Extensive information suggests the stress nuclear perfusion imaging is the best validated technique for predischarge risk stratification with unstable angina patients who have been medically stabilized. Early information suggests avoidance of unecessary coronary angiography or revascularization is the cost effective strategy

We investigated the washout of 123 I-BMIPP from early and delayed SPECT in 28 patients with vasospastic angina from the standpoint of the intervals from the last angina attack. We divided myocardial wall into 13 segments from the early and delayed SPECT, and visually classified into four grades of defect score ranged from 0 (normal) to 3 (severe defect). Early and delayed severity scores were calculated as a total of defect scores in 3 vessel territories, and washout scores (WS) as (delayed severity score early severity score)/ number of segments. WS of the group within 1 month from last angina attack was compared with the groups more than 1 month. In the territory of the right coronary artery, the group within 1 month showed significantly higher WS than groups more than 1 month (p 123 I-BMIPP may reflect the clinical course of vasospastic angina.

Ranolazine is an antianginal agent that was approved in the EU in 2008 as an add-on therapy for symptomatic chronic angina pectoris treatment in patients who are inadequately controlled by, or are intolerant to, first-line antianginal therapies. These patients' quality of life is significantly affected by more frequent angina events, which increase the risk of revascularization. To assess the cost-utility of ranolazine versus placebo as an add-on therapy for the symptomatic treatment of patients with chronic angina pectoris in Spain. A decision tree model with 1-year time horizon was designed. Transition probabilities and utility values for different angina frequencies were obtained from the literature. Costs were obtained from Spanish official DRGs for patients with chronic angina pectoris. We calculated the incremental cost-utility ratio of using ranolazine compared with a placebo. Sensitivity analyses, by means of Monte Carlo simulations, were performed. Acceptability curves and expected value of perfect information were calculated. The incremental cost-utility ratio was €8,455 per quality-adjusted life-year (QALY) per patient in Spain. Sensitivity analyses showed that if the decision makers' willingness to pay is €15,000 per QALY, the treatment with ranolazine will be cost effective at a 95 % level of confidence. The incremental cost-utility ratio is particularly sensitive to changes in utility values of those non-hospitalized patients with mild or moderate angina frequency. Ranolazine is a highly efficient add-on therapy for the symptomatic treatment of chronic angina pectoris in patients who are inadequately controlled by, or intolerant to, first-line antianginal therapies in Spain.

Twelve patients with stable angina and 12 patients with unstable angina underwent rest iodine-123-β-methyl-iodophenyl-pentadecanoic acid (BMIPP), dipyridamole stress thallium scintigraphy and delayed thallium scintigraphy. In stable angina, sensitivity for detecting ischemic segments was higher in dipyridamole thallium (74%) than rest BMIPP (48%) images (p<0.05), but there was no significant difference between the 2 images in unstable angina. In unstable angina, the incidence of segments with higher defect scores on BMIPP images than on delayed thallium images and the opposite pattern was 27 and 5 (p<0.01). In stable angina, there was no difference. The mean defect score on BMIPP (6.3±5.6) was higher than that on delayed thallium scintigraphy (2.9±2.7) and it was almost the same as on the initial dipyridamole stress test (6.5±5.2). In conclusion, BMIPP scintigraphy is safer and may be as useful in detecting myocardial ischemia in patients with unstable angina as thallium scintigraphy. (author)

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). When patients were subdivided according to both angina pectoris and heart failure, those with one or both of these risk markers had significantly increased mortality (p 0.03) and reinfarction (p 0...

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

Perfusion defects and 201 Tl redistribution on scintigraphic images were compared with clinical findings in 140 patients with myocardial infarction (consisting of 84 with single vessel disease and 56 with double vessel disease), 28 patients with one vessel disease not accompanied by infarction, and 18 healthy persons who underwent left coronary arteriography and 201 Tl stress myocardial scintigraphy. In 30 patients with single vessel disease accompanied by postinfarction angina pectoris, perfusion defects was smaller and Tl redistribution was larger than those in 54 patients with single vessel desease not accompanied by it. The 30 patients with postinfarction angina pectoris had a slight abnormality of left ventricular contraction and marked stenosis of 90% or more of the vessels. These findings were similar to those in the 28 angina patients who had one vessel disease but not accompanied by infarction. In 56 cases of double vessel disease, Tl redistribution was significantly larger in the group with angina than in the group without it. These results suggested that ischemia in an infarct area plays an important role as a mechanism for postinfarction angina pectoris. (Namekawa, K.)

Patients with a history of typical angina but negative exercise electrocardiography represent a subgroup with an intermediate likelihood of having coronary artery disease and future cardiac events. A retrospective study of the prognostic utility of stress-redistribution thallium-201 scintigraphy was performed in 190 such patients. A second group of 203 patients with typical angina and a positive exercise electrocardiogram were analyzed for comparative scintigraphic purposes. The cardiac event rate for the 144 negative exercise electrocardiogram patients with normal thallium results was 5 vs 15% in the 46 patients with abnormal thallium results (p = 0.01). These patients were further stratified into high (14 to 18%), intermediate (9%) and low (less than 2%) risk groups for future cardiac events based on combining the thallium results with the percentage of maximal predicted heart rate achieved. A multivariate analysis revealed that an abnormal thallium result was the only significant correlate of future cardiac events. Mechanisms responsible for the discordant finding of a negative exercise electrocardiogram in patients with typical angina include (1) false-positive angina symptomatology in low prevalence coronary artery disease groups in whom the thallium test is negative, and (2) electrocardiographically silent ischemia in patients in whom the thallium test is positive. These findings reveal that thallium stress-redistribution scintigraphy can be used to stratify 1-year prognosis in this subgroup of patients with typical angina and negative exercise electrocardiograms

Non-communicable diseases (NCDs) are becoming a major source of the national disease burden in Myanmar with potentially serious economic implications. Using data on 5484 households from the World Health Survey (WHS), this study assessed the household-level economic burden of two chronic conditions, angina and asthma, in Myanmar. Propensity score matching (PSM) and coarsened exact matching (CEM) methods were used to compare household out-of-pocket (OOP) spending, catastrophic and impoverishment effects, reliance on borrowing or asset sales to finance OOP healthcare payments and employment among households reporting a member with angina (asthma) to matched households, with and without adjusting for comorbidities. Sensitivity analyses were carried out to assess the impacts of alternative assumptions on common support and potential violations of the assumption of independence of households being angina (asthma) affected and household economic outcomes, conditional on the variables used for matching (conditional independence). Households with angina (asthma) reported greater OOP spending (angina: range I$1.94-I$4.31; asthma: range I$1.53-I$2.01) (I$1 = 125.09 Myanmar Kyats; I$=International Dollar) almost half of which was spending on medicines; higher rates of catastrophic spending based on a 20% threshold ratio of OOP to total household spending (angina: range 6-7%; asthma: range 3-5%); greater reliance on borrowing and sale of assets to finance healthcare (angina: range 12-14%; asthma: range 40-49%); increased medical impoverishment and lower employment rates than matched controls. There were no statistically differences in OOP expenses for inpatient care between angina-affected (asthma-affected) households and matched controls. Our results were generally robust to multiple methods of matching. However, conclusions for medical impoverishment impacts were not robust to potential violations of the conditional independence assumption. Myanmar is expanding public

Intracoronary thrombolytic infusions were used in 10 patients with unstable angina and high risk of myocardial infarction (MI). Streptokinase (500.000 units per hour) was used in 9 patients, and urokinase, in one. Vascular recanalization was achieved in 4 cases where angiografhy, showed coronary arterial occlusion by a thrombus. Myocardial infarction developed in 8 patients (large-focal in 6 and small focal in 2) within 1 to 16 days after the thrombolytic infuson. Therefore, short-term local thrombolytic infusion fails to prevent myocardial infarction in patients with unstable angina

Ranolazine is a novel antianginal medication approved for the treatment of chronic angina. There are only limited data concerning the efficacy of ranolazine in reducing healthcare resource utilization in patients with refractory angina pectoris. The primary objective of this analysis was to evaluate the efficacy and safety of ranolazine in refractory angina pectoris. In addition, the impact of ranolazine on healthcare resource utilization was assessed. Consecutive patients with refractory angina pectoris treated with ranolazine at two cardiology practices in the state of Nebraska were included in this analysis. The Canadian Cardiovascular Society (CCS) angina class and frequency and type of healthcare resource consumption were determined during the 12 months prior to and the 12 months after initiation of ranolazine. A total of 150 pts (64 % men) with a mean age of 66 ± 12 years were included in this analysis. All patients had previously undergone coronary revascularization. Nitrates, β-adrenoceptor antagonists (β-blockers), and calcium antagonists (calcium channel blockers) were being used in 83, 97, and 75 % of patients, respectively. During ranolazine treatment, a significant improvement in CCS angina class was observed, with 23 patients improving by one class and no patient experiencing a deterioration in functional class (p = 0.025). A total of 53 side effects occurred in 28 (19 %) patients receiving ranolazine. Of those patients with side effects, four required dose reduction and seven required drug discontinuation. The frequency of clinic visits and emergency room visits was lower during ranolazine treatment, but the differences in frequency were not significant. The number of patients hospitalized and the number of hospitalizations were significantly lower during ranolazine therapy than in the pre-ranolazine study period (p = 0.002). Ranolazine improved the CCS angina class and reduced hospitalizations over a 12-month follow-up period in a group

'Variant' angina: Evidence for small vessel coronary artery spasm

Pfisterer, M.; Mueller-Brand, J.; Cueni, T.; Luetold, B.; Burkart, F.; Basel Univ.

1980-01-01

A unique case of 'variant' angina pectoris has been observed in a patient with normal coronary arteries and typical chest pain appearing spontaneously at rest, and repeatedly provoked by ergonovine maleate (0.1 mg iv) associated with large transmural perfusion defects on 201 TI-imaging (after ergonovine) and a marked increase in T wave voltage despite no demonstrable spasm of a major coronary artery after the same doses of ergonovine. While saline solution could not provoke chest pain and treatment with a beta-blocking agent increased the frequency of ischemic attacks, a calcium antangonist therapy reduced and eventually eliminated the attacks. Thus, this case provides evidence for yet another aspect of a 'variant' form of angina pectoris: small vessel coronary artery spasm. (orig.) [de

Full Text Available Resumen: En los últimos años se han desarrollado diversos métodos para controlar sistemas mecánicos subactuados. De hecho, dichos métodos no lineales han conseguido resolver problemas muy interesantes desde el punto de vista de control. Sin embargo, para obtener una solución con estos métodos, normalmente es necesario resolver un sistema de ecuaciones diferenciales en derivadas parciales, lo cual no siempre es posible. En este artículo, se presenta una metodología constructiva para diseñar un controlador para una clase de sistemas mecánicos inestables en bucle abierto y con grado de subactuación uno. Para el diseño se emplean principalmente las técnicas de linealización por realimentación y Lyapunov. La metodología consiste en proponer una salida ficticia que se pueda rediseñar de forma constructiva para resolver el problema planteado, dando lugar a una ley de control explícita, que permite tener en cuenta la fricción incluso en las coordenadas no actuadas.

Several animal experiments on acute myocardial infarction (AMI) have shown that the cardioprotective effects of ischemic preconditioning are more significant in hypertensive subjects. However, because there are no clinical data on the impact of hypertension on ischemic preconditioning in patients with AMI, whether clinical ischemic preconditioning of prodromal angina was beneficial in AMI patients with hypertension was investigated in the present study. 125 patients with a first anterior AMI who had undergone successful reperfusion therapy were divided into 2 groups, with or without hypertension, and into 2 further subgroups based on the presence or absence of prodromal angina. Dual-isotope (thallium-201(TL)/Tc-99m pyrophosphate) single-photon emission computed tomography (SPECT) was performed within 1 week of reperfusion therapy. Left ventricular (LV) function and LV mass index (LVMI) were measured by left ventriculography and echocardiography, respectively. In patients without hypertension, prodromal angina resulted in significantly less myocardial damage on TL-SPECT, better LV ejection fraction and a greater myocardial blush grade compared to patients without prodromal angina. However, these cardioprotective effects of prodromal angina were significantly diminished in hypertensive patients. Importantly, the myocardial salvage effects of prodromal angina showed a significant negative correlation with LVMI, which was significantly greater in hypertensive patients. The cardioprotective effects of prodromal angina were attenuated in patients with hypertension. Hypertensive LV hypertrophy may crucially limit the effects of ischemic preconditioning in AMI.

To estimate the prevalence of angina pectoris in the Brazilian adult population with the use of the Rose questionnaire for angina in the National Health Survey (PNS 2013). Population survey representing the Brazilian population aged 18 years and older, with probability carried out sampling in three stages. The interview records of 60,202 individuals were obtained in the country. The respondent was presented with the short Rose questionnaire with three questions, adapted by Lawlor in 2003 and validated in Brazil, to identify angina pectoris grade I (mild) and II (moderate/severe). The prevalence rate was calculated with a 95% confidence interval (95%CI) according to sex, age, education, and race/color. The prevalence of mild angina (grade I) was of 7.6% (95%CI 7.2 - 8.0) for the entire population, more frequently in women - 9.1% (95%CI 8.5 - 9.7) - than in men - 5.9% (95%CI 5.3 - 6.4). The frequency of moderate/severe angina (grade II) was of 4.2 (95%CI 3.9 - 4.5), also more common in women - 5.2% (95%CI 4.7 - 5.6) - than in men - 3.0% (95%CI 2.7 - 3.4). The prevalence of angina by age group increased progressively with age. The prevalence of angina of any sort was inverse to years of formal study. Despite the higher value of the presence of angina in black people, there was no significant difference by race/skin color. The high prevalence rate of angina pectoris in the population aged 18 years and above was consistent with studies in other countries, revealing the importance of coronary heart disease as a public health problem.

To evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris. Block randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina. The 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P0.05), while they were signifificantly better for KA in the CCSI and II subgroups (Pangina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).

Tongxinluo capsule is a medicine consisting of traditional Chinese herbs and insects used for cardiovascular diseases in China and some other Asian countries. To date the evidence of its effect has not previously been subject to systematic review, making it difficult to derive robust conclusions about its actual benefits, and indeed, possible harms. To assess systematically the effects of tongxinluo capsule in people with unstable angina pectoris. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library, Issue 4 2004, MEDLINE, EMBASE, Chinese Biomedical Database, China National Knowledge Infrastructure, Japana Centra Revuo Medicina (all 1995 to 2005). We also handsearched the relevant Chinese journals, checked with manufacturers and registers of ongoing studies. Randomised trials comparing either tongxinluo capsule only or standard treatment plus tongxinluo capsule with standard treatment or other anti-angina pectoris drugs, placebo or no intervention. Two authors identified relevant studies for the review independently and went on to abstract data, and assess trial quality. Authors of included studies were contacted to obtain further information as required. 18 short term follow-up trials involving 1413 people were included. The studies did not provide strong support of a benefit of tongxinluo for reducing the combined outcome of acute myocardial infarction, angioplasty (PTCA) coronary artery bypass graft (CABG) and sudden death or all-cause mortality (RR 0.42, 95% CI 0.07 to 2.59, P=0.35; RR 0.33, 95% CI 0.01to 7.78, P=0.49, respectively). Tongxinluo reduced the frequency of acute angina attacks (WMD -1.20, 95%CI -1.38 to -1.02, P<0.00001 and RR -2.36, 95%CI -2.53 to -2.18, P<0.00001, respectively), improved ECG (RR 1.31, 95% CI 1.08 to 1.57, P=0.005) and angina symptoms (RR 1.21, 95% CI 1.06 to 1.40; P=0.007). Tongxinluo in combination with routine angina therapy appears to reduce the risk of subsequent AMI, PTCA or CABG

Some patients of ischemic heart disease have low uptake in 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)

Angina pectoris impairs patients' quality of life. In order to assess its impact on quality of life, a questionnaire was developed using a literature review and interviews with patients and clinicians. It consisted of a general profile (SF-36) which measured functional status, well-being, perceived health, and a specific index, the Angina Pectoris Quality of Life Questionnaire, supplemented by new items. The acceptability, internal consistency reliability and clinical validity of this 70-item questionnaire were analysed in a cross-sectional study. Of 197 coronary patients approached, 93% (n = 184) agreed to participate and 86% (n = 170) returned the mailed questionnaire. Mean age of patients was 67 years (+/- 10); 79% were male and 70% were retired. Sixty patients were asymptomatic and 110 reported anginal crises (Canadian Cardiovascular Society Classification: class I: 48; II: 37; III: 13; IV: 0; V: 12). Globally, angina pectoris was found to affect each quality of life concept measured: physical functioning, well-being, and perceived health. Quality of life profiles worsened in accordance with increasing severity of the condition, as stratified by angina pectoris class. Asymptomatic patients reported better general and specific profiles. These results support the feasibility and usefulness of evaluating quality of life using the questionnaire. The validation of the data is very encouraging and enables the questionnaire to be used in clinical trials.

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.

Since the arrival of the universal definition of myocardial infarction more sensitive troponin assays have been developed. How these occurrences have influenced the proportions and clinical features of the components of acute coronary syndrome have not been studied prospectively in unselected hospital patients. During 2010 we evaluated all patients in whom cardiac troponin I had been measured at a single university hospital. The diagnosis of acute myocardial infarction (ST-elevation myocardial infarction [STEMI] or non-ST-elevation myocardial infarction [NSTEMI]) was established in cases of a rise and/or fall of cardiac troponin I together with cardiac ischemic features. Patients with unstable chest discomfort and cardiac troponin I values below the decision limit of myocardial infarction were diagnosed as having unstable angina pectoris. The definition of acute coronary syndrome included unstable angina pectoris, NSTEMI, and STEMI. Mortality data were obtained from the Danish Civil Personal Registration System. Of 3762 consecutive patients, 516 had acute coronary syndrome. Unstable angina pectoris was present in 7%, NSTEMI in 67%, and STEMI in 26%. The NSTEMI patients were older, more frequently women, and had more comorbidities than patients with unstable angina pectoris and STEMI. At median follow-up of 3.2 years 195 patients had died: 14% of unstable angina pectoris, 45% of NSTEMI, and 25% of STEMI patients. Age-adjusted log-rank statistics revealed differences in mortality: NSTEMI vs unstable angina pectoris (P = .0091) and NSTEMI vs STEMI (P = .0045). The application of the universal definition together with the use of a contemporary troponin assay seems to have reduced the proportion of patients with unstable angina pectoris to the benefit of patients with NSTEMI. Despite this, NSTEMI patients have a sustained higher mortality than patients with STEMI. Copyright © 2015 Elsevier Inc. All rights reserved.

To assess the effect (harms and benefits) of nitrates for stable angina. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. Randomized controlled trials with both parallel and crossover design were included. The following outcome measures were evaluated: number of angina attacks weekly and nitroglycerin consumption, quality of life, total exercise duration, time to onset of angina and time to 1 mm ST depression. Fifty-one trials with 3595 patients meeting inclusion criteria were analyzed. Both intermittent and continuous regimens of nitrates lengthened exercise duration significantly by 31 and 53 s respectively. The number of angina attacks was significantly reduced by 2.89 episodes weekly for continuous administration and 1.5 episodes weekly for intermittent administration. With intermittent administration, increased dose provided with 21 s more length of exercise duration. With continuous administration, exercise duration was pronged more in low-dose group. Quality of life was not improved by continuous application of GTN patches and was similar between continuous and intermittent groups. In addition, 51.6% patients receiving nitrates complained with headache. Long-term administration of nitrates was beneficial for angina prophylaxis and improved exercise performance but might be ineffective for improving quality of life. With continuous regimen, low-dose nitrates were more effective than high-dose ones for improving exercise performance. By contrast, with intermittent regimen, high-dose nitrates were more effective. In addition, intermittent administration could bring zero-hour effect. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

The Effect of Chinese Herbal Medicine Gualouxiebaibanxia Decoction for the Treatment of Angina Pectoris: A Systematic Review

2016-01-01

We systematically assess the current clinical evidence of Gualouxiebaibanxia (GLXBBX) decoction for the treatment of angina pectoris (AP). We included RCTs testing GLXBBX against conventional drugs and GLXBBX combined with conventional drugs versus conventional drugs. 19 RCTs involving 1730 patients were finally identified, and the methodological quality was evaluated as generally low. The results of the meta-analysis showed that GLXBBX alone had significant effect on improving angina symptoms (RR: 1.24, 95% CI 1.14 to 1.35; P angina symptoms (RR: 1.17 [1.12,1.22]; P angina symptoms in participants with AP. However, the evidence remains weak due to the poor methodological quality of the included studies. More rigorous trials are needed to confirm the results. PMID:27777598

Las mutaciones inestables, nuevo reto para el consejo genético de enfermedades hereditarias

Directory of Open Access Journals (Sweden)

Patricia Cuenca

2004-09-01

Full Text Available Las mutaciones inestables constituyen un tipo de alteración genética descubierta en la década de los noventa. En condiciones normales, regiones específicas de los genes están constituidas por repeticiones de una secuencia corta que puede ser de tres, cuatro, cinco o más nucleótidos; por ejemplo CAG, CGG, ATTCT, etc. Este nuevo tipo de mutación consiste en un aumento en la cantidad de éstas repeticiones, lo que causa una alteración en la expresión de dichos genes. Son inestables porque se ha observado que el tamaño de la secuencia repetida varía cuando las células se dividen por mitosis o meiosis, lo cual tiene implicaciones sobre la herencia y por consiguiente sobre el consejo genético que debe brindarse a los afectados. Estas mutaciones se han encontrado en genes importantes para la función neurológica normal del ser humano, donde pueden alterar el transporte de los ARN desde el núcleo al citoplasma, provocar la inactivación del gen o producir una proteína con funciones nuevas. La mayoría de las enfermedades causadas por estas mutaciones afectan el sistema nervioso, son degenerativas y presentan el fenómeno de anticipación genética, es decir que los afectados dentro de una familia se enfermarán más jóvenes y en forma más severa con el paso de las generaciones. La cantidad de repeticiones de la secuencia repetida presenta una correlación negativa con la edad de manifestación, así como una correlación positiva con la severidad de la enfermedad. En este momento existen veinte padecimientos identificados que son causados exclusivamente por este tipo de mutación. Este trabajo es una breve revisión actualizada del tema.Unstable mutations, new challenges for genetic counseling of inherited disorders. Unstable mutations or amplification of DNA tandem repeats sequences constitute a new kind of genetic alteration discovered in the 90´s that cause hereditary diseases.

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.

Serial thallium-201 imaging at rest in patients with unstable and stable angina pectoris: relationship of myocardial perfusion at rest to presenting clinical syndrome

International Nuclear Information System (INIS)

Brown, K.A.; Okada, R.D.; Boucher, C.A.; Phillips, H.R.; Strauss, H.W.; Pohost, G.M.

1983-01-01

In order to determine whether there are differences in myocardial perfusion at rest among patients with various unstable and stable angina syndromes, serial thallium-201 imaging was performed at rest in 19 patients presenting with rapidly worsening exertional angina (unstable angina, group A), 12 patients with rest angina alone without exertional symptoms (unstable angina, group B), and 34 patients with chronic stable angina. No patient had an episode of angina within 4 hours of study. Nineteen of 19 (100%) patients in group A demonstrated transient defects compared to only 3 of 12 (25%) patients in group B (p less than 0.0001) and 4 of 34 (12%) stable angina patients (p less than 0.0001). The majority of zones demonstrating transient defects in group A were associated with hypokinesis of the corresponding left ventriculogram segment without associated ECG evidence of previous infarction. There were no significant differences in the frequency of persistent thallium defects, severity of angiographic coronary artery disease, or frequency of regional wall motion abnormalities of myocardial segments supplied by stenotic coronary arteries among the three groups of patients. Transient defects have been shown to reflect reduction in regional coronary blood flow to viable myocardium. Therefore, we conclude that regional resting hypoperfusion of viable myocardium is far more common in patients with exertional unstable angina symptoms than in patients with rest angina alone or chronic stable angina

With the rising incidence as well as the medical expenditure among patients with unstable angina pectoris, the research aimed to investigate the inpatient medical expenditure through the combination of diagnosis-related groups (DRGs) among patients with unstable angina pectoris in a Grade A tertiary hospital to conduct the referential standards of medical costs for the diagnosis. Single-factor analysis and multiple linear stepwise regression method were used to investigate 3933 cases between 2014 and 2016 in Beijing Hospital (China) whose main diagnosis was defined as unstable angina pectoris to determine the main factors influencing the inpatient medical expenditure, and decision tree method was adopted to establish the model of DRGs grouping combinations. The major influential factors of inpatient medical expenditure included age, operative method, therapeutic effects as well as comorbidity and complications (CCs) of the disease, and the 3933 cases were divided into ten DRGs by four factors: age, CCs, therapeutic effects, and the type of surgery with corresponding inpatient medical expenditure standards setup. Data of nonparametric test on medical costs among different groups were all significant (P angina pectoris is conducive in standardizing the diagnosis and treatment behaviors of the hospital and reducing economic burdens among patients.

The aim of this prospective study was to determine the value of quantitative exercise thallium-201 scintigraphy for predicting short-term outcome in patients after percutaneous transluminal coronary angioplasty (PTCA). Quantitative exercise thallium-201 scintigraphy was performed 2.2 +/- 1.2 weeks after successful PTCA in 68 asymptomatic patients, 64 (94%) of whom had class III or IV angina before the procedure. Clinical follow-up was obtained in all patients at a mean of 10 +/- 2 months and all were followed for at least 6 months; 45 patients (66%) remained asymptomatic during follow-up and 23 (34%) developed recurrent class III or IV angina at a mean of 2.6 +/- 1.2 months. Multivariate analysis of 22 clinical, angiographic and exercise test variables revealed that thallium-201 redistribution, any thallium scan abnormality, presence of a distal stenosis and treadmill time were the only significant predictors of recurrent angina after PTCA. Using a stepwise discriminant function model, thallium-201 redistribution was the only significant independent predictor. Despite its prognostic value relative to other variables as a predictor, thallium redistribution at 2 weeks after PTCA was only detected in 9 of the 23 patients (39%) who subsequently developed recurrent angina, although only 2 of the 45 patients (9%) who remained asymptomatic during follow-up demonstrated thallium-201 redistribution at the time of early testing. After repeat angiography was performed in 17 of the 23 patients with recurrent angina, 14 (82%) demonstrated restenosis and 3 (18%) had worse narrowing distal to or remote from the site of dilatation

Purpose: Based on our preclinic studies with autologous unfractionated bone marrow (AUBM) via coronary sinus with transitory occlusion, a clinic study in patients with chronic stable angina was designed. The objectives were to evaluate safety, tolerance and feasibility. Methods and materials: A multicenter prospective study with inclusion and exclusion criteria defined by an Independent Clinical Committee was carried out. Fourteen patients underwent transcoronary sinus administration of freshly aspirated and filtered AUBM (60-120 ml). Safety and tolerance were evaluated. Feasibility was evaluated with Seattle Angina Questionnaire (SAQ), Canadian Cardiovascular Society (CCS) angina classification (baseline-Day 180), myocardial perfusion (baseline-Day 90) with independent core laboratory and coronary angiography (baseline and Day 30). Results: There were no changes in the safety and tolerance parameters. Preliminary clinical efficacy at Day 180 disclosed a significant improvement of 38%, evaluated by the SAQ. The CCS angina classification shows that the mean angina class was 3.0±0.55 at baseline and improved to 2.0±0.00 at Day 180 (P<.001). Semiquantitative radionuclide perfusion imaging (core lab) showed a significant improvement at Day 90 in 13/14 patients, with a mean improvement of 24% at rest (P<.01) and 33% at stress (P<.05). Coronary angiography showed more collateral vessels in 9/14 patients. Conclusions: We can conclude that AUBM via coronary sinus with transitory occlusion is tolerable and safe. Significant improvement in the myocardial perfusion at Day 90 and in the quality of life at Day 180 was observed

A previous Cochrane review has shown that exercise-based cardiac rehabilitation (CR) can benefit myocardial infarction and post-revascularisation patients. However, the impact on stable angina remains unclear and guidance is inconsistent. Whilst recommended in the guidelines of American College of Cardiology/American Heart Association and the European Society of Cardiology, in the UK the National Institute for Health and Care Excellence (NICE) states that there is "no evidence to suggest that CR is clinically or cost-effective for managing stable angina". To assess the effects of exercise-based CR compared to usual care for adults with stable angina. We updated searches from the previous Cochrane review 'Exercise-based cardiac rehabilitation for patients with coronary heart disease' by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, DARE, CINAHL and Web of Science on 2 October 2017. We searched two trials registers, and performed reference checking and forward-citation searching of all primary studies and review articles, to identify additional studies. We included randomised controlled trials (RCTs) with a follow-up period of at least six months, which compared structured exercise-based CR with usual care for people with stable angina. Two review authors independently assessed the risk of bias and extracted data according to the Cochrane Handbook for Systematic Reviews of Interventions. Two review authors also independently assessed the quality of the evidence using GRADE principles and we presented this information in a 'Summary of findings' table. Seven studies (581 participants) met our inclusion criteria. Trials had an intervention length of 6 weeks to 12 months and follow-up length of 6 to 12 months. The comparison group in all trials was usual care (without any form of structured exercise training or advice) or a no-exercise comparator. The mean age of participants within the trials ranged from 50 to 66 years, the

Coronary angiography and the assessment of blood lipoproteins were carried out in 43 patients with recent (not more than three months old) angina. A rise in cholesterol above 270 mg/dl and/or triglycerids bove 200 mg/dl was demonstrated in 19. The level of α-cholesterol was below 35 mg/dl in 11 of 24 normolipidemic patients. The apoprotein B/apoprotein AI ratio was above 1.0 in 7 of 13 patients with normal cholesterol levels. Plasma phospholipid composition was disturbed in 4 of 6 patients with normal apoprotein B/apoprotein AI rations. Therefore atherogenic changes in plasma lipoprotein composition were found in 95% of patients with recent angina

La informatización de la atención primaria de salud

Directory of Open Access Journals (Sweden)

Rodolfo J. Stusser Beltranena

Full Text Available La informatización de la atención primaria de salud se percibe como un problema que se soluciona creando redes computarizadas entre los consultorios y policlínicos. El artículo brinda una visión panorámica del estado en que se encuentra el arte de la informatización de la atención primaria y la medicina general integral, en el mundo y en Cuba. Para ello, se sintetiza el origen prehistórico de ese nivel de atención y de la especialidad, así como el desarrollo contemporáneo de la informática y sus aplicaciones médicas; se define igualmente la atención primaria y su informática; se resumen los sistemas de información, las aplicaciones informáticas y sus desafíos; y se ofrece una visión práctica de la historia clínica-electrónica: corazón de la informática de atención primaria de salud y medicina general integral. Se concluye que Cuba ha trabajado 20 años informatizando la dispensarización y estadísticas para la gerencia de servicios de este nivel de atención, pero que también podría trabajar con el enfoque centrado en la vida del paciente, que contribuiría a crear una clasificación integradora de la salud con la enfermedad, y a computarizar la información y la toma de decisiones clínicas en el consultorio del médico, y en el futuro hasta en el hogar del paciente, elevando directamente la calidad de la atención primaria de salud.

Full Text Available La angina de pecho crónica estable es un síndrome clínico caracterizado por dolor o malestar precordial secundario a isquemia miocárdica y sin características clínicas de inestabilidad. El debate actual sobre esta entidad clínica incluye tres aspectos fundamentales: diagnóstico, prevalencia e impacto socioeconómico, y tratamiento médico frente a revascularización miocárdica. En los últimos cuatro años se han dado a conocer los resultados de varios estudios multicéntricos de gran importancia que compararon tratamiento médico con revascularización miocárdica y cirugía de revascularización frente a intervención coronaria percutánea; además, han mejorado las técnicas de revascularización y existe abundante información sobre la eficacia de nuevos fármacos antiisquémicos. El presente trabajo tiene como objetivo hacer una revisión de los aspectos actuales más importantes relacionados con la angina de pecho estable y su tratamiento, publicados en la literatura especializada.

We evaluated 193 consecutive unstable angina patients by clinical features, hospital course and electrocardiography. All patients were managed medically. Of the 193 patients, 150 (78%) had a technetium-99m pyrophosphate (Tc-PYP) myocardial scintigram after hospitalization. Of these, 49 (33%) had positive scintigrams. At a follow-up of 24.9 +- 10.8 months after hospitalization, 16 of 49 patients (33%) with positive scintigrams died from cardiac causes, compared with six of 101 patients (6%) with negative scintigrams (p < 0.001). Of 49 patients with positive scintigrams, 11 (22%) had had nonfatal myocardial infarction at follow-up, compared with seven of 101 patients (7%) with negative scintigrams (p < 0.01). Age, duration of clinical coronary artery disease, continuing angina during hospitalization, ischemic ECG, cardiomegaly and a history of heart failure also correlated with cardiac death at follow-up. Ischemic ECG and a history of angina with a crescendo pattern also correlated with nonfatal infarction at follow-up. Patients with continuing angina, an ischemic ECG and a positive scintigram constituted a high-risk unstable angina subgroup, with a survival rate of 58% at 6 months, 47% at 12 months and 42% at 24 and 36 months. We conclude that the assessment of clinical features, hospital course, ECG and Tc-PYP scintigraphy may be useful in identifying high-risk unstable angina patients

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)

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

Ethnicity and smoking are well-known risk factors for the pathogenesis of coronary vasospasm. Oxidative stress induced by smoking plays a crucial role in coronary vasospasm, but is not enough to account for the pathogenesis of coronary vasospasm, indicating that genetic factors are strongly involved. The study group comprised 162 vasospastic angina patients (VSAs), 61 microvascular angina patients (MVAs) and 61 non-responders (NRs) diagnosed by acetylcholine provocation test. Four polymorphisms of the oxidative stress related genes, cytochrome b-245, alpha polypeptide gene (CYBA) C242T and A640G, paraoxonase 1 gene (PON1) A632G, phospholipase A2 group VII gene (PLA2G7) G994T were genotyped. Allele frequency of PON1 632-G was significantly higher in both the VSA with dominant fashion and the MVA with recessive fashion compared with NR. This association was strongly influenced by gender in the MVA only. There were no significant associations between the other polymorphisms and coronary vasospasm. In addition, the allele frequency of PON1 632-G in the Japanese was higher than in Caucasians. There was a significant association between PON1 A632G polymorphism and MVA as well as VSA, but the impact of this on VSA and MVA is different in the Japanese.

Cigarette smoking is not only one of the most important risk factors for coronary artery disease, but also anginal attacks often occur during smoking. Coronary vasoconstriction is considered to be one of the mechanisms which cause anginal episodes. Thirty patients with angina pectoris, 27 men and 3 women, were investigated. Group I comprised 22 patients with rest angina and group II consisted of 8 patients with effort angina. Five minutes after smoking one cigarette, a first study of 20l Tl myocardial SPECT was performed. Consequently, after sublingual administration of isosorbide denitrate, a second SPECT was done. Most cases improved and it was recognized as positive when changes of localized perfusion defects were observed between both SPECTs. In the group I, 19 out of 22 patients (86%) were positive, but in the group II, 2 out of 8 (25%) were positive. The differences were statistically significant (p<0.05). By the examination of coronarty angiography in 20 patients, the result of myocardial scintigraphy using cigarette smoking and isosorbide dinitrate seemed inversely proportional to the severity of narrowing of the coronary artery. In addition, background factors including risk factors were also compared for both groups. Because the result of this myocardial scintigraphy was positive in the rest angina group and in the group with minimal coronary arteriogrpahic abnormalities, it seggests that myocardial scintigraphy using cigarette smoking and isosorbide dinitrate is useful as a non-invasive auxiliary diagnostic method to detect coronary spasm or coronary vasoconstriction-prone angina pectoris including silent myocardial ischemia.

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.

Traditional Chinese medicine (TCM) injection is widely used to treat angina pectoris in China. This overview aims to systematically summarize the general characteristics of systematic reviews (SRs) on TCM injection in treating angina, and assess the methodological and reporting quality of these reviews. We searched PubMed, Embase, the Cochrane Library and four Chinese databases from inception until March 2013. Data were extracted according to a preset form. The AMSTAR and PRISMA checklists were used to explore the methodological quality and reporting characteristics of included reviews, respectively. All data analyses were descriptive. 46 SRs involving over 57,463 participants with angina reviewing 23 kinds of TCM injections were included. The main outcomes evaluated in the reviews were symptoms (43/46, 93.5%), surrogate outcomes (42/46, 91.3%) and adverse events (41/46, 87.0%). Few reviews evaluated endpoints (7/46, 15.2%) and quality of life (1/46, 2.2%). One third of the reviews (16/46, 34.8%) drew definitely positive conclusions while the others (30/46, 65.2%) suggested potential benefits mainly in symptoms, electrocardiogram and adverse events. With many serious flaws such as lack of a protocol and inappropriate data synthesis, the overall methodological and reporting quality of the reviews was limited. While many SRs of TCM injection on the treatment of angina suggested potential benefits or definitely positive effects, stakeholders should not accept the findings of these reviews uncritically due to the limited methodological and reporting quality. Future SRs should be appropriately conducted and reported according to international standards such as AMSTAR and PRISMA, rather than published in large numbers.

Study protocol: a randomised controlled trial investigating the effect of exercise training on peripheral blood gene expression in patients with stable angina

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.

Intravascular stenting in the superior mesenteric artery for chronic abdominal angina.

Science.gov (United States)

Busquet, J

1997-11-01

Abdominal angina is an early clinical expression of occlusive mesenteric arterial insufficiency, a condition that requires aggressive treatment to prevent intestinal infarction. We report a case of chronic mesenteric ischemia in a young polyvascular man who had symptoms of abdominal angina. An aortic angiogram revealed a significant ostial stenosis of the superior mesenteric artery (SMA) associated with an occlusion of the inferior mesenteric artery. After predilation of the ostial portion of the SMA, significant residual stenosis remained. A balloon-expandable Palmaz P154 stent was deployed, restoring adequate luminal dimensions and blood flow. The patient was discharged after 2 days and remains asymptomatic at 5 months. Intraluminal stenting for treatment of mesenteric ischemia represents a viable alternative to surgical revascularization in selected cases.

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.

Epidural spinal cord stimulation (SCS) provides symptom relief in refractory angina pectoris, but its mechanism of action remains incompletely understood. We studied effects of short-term SCS therapy on myocardial ischaemia tolerance, myocardial perfusion reserve (MPR), and endothelium-mediated vasodilatation induced by cold pressor test (CPT) in patients with refractory angina pectoris. We prospectively recruited 18 patients with refractory angina pectoris and studied them after implantation of SCS device at baseline before starting the therapy and after 3 weeks of continuous SCS therapy. Myocardial ischaemia was evaluated by dobutamine stress echocardiography. Global and regional myocardial blood flow (MBF) were measured using positron emission tomography and (15)O-water at rest, during adenosine stress, and in response to CPT. Systemic haemodynamics were comparable before and after 3 weeks of SCS at rest, during adenosine stress and during CPT. Appearance of angina pectoris induced by dobutamine stress was delayed after SCS therapy. Global MPR increased (P = 0.02) from 1.7 ± 0.6 at baseline to 2.0 ± 0.6 after 3-week SCS therapy. This was associated with a significant reduction in global MBF at rest and increase in MBF induced by adenosine in the ischaemic regions. Global MBF response to CPT was improved after SCS (0.27 ± 0.20 vs. 0.40 ± 0.15, P = 0.03). Short-term SCS therapy improved myocardial ischaemia tolerance, absolute MPR, and endothelium-mediated vasomotor function in refractory angina pectoris, indicating that this therapy can alleviate myocardial perfusion abnormalities in advanced CAD.

This study was undertaken to assess the diagnostic value of resting 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). 123 I-BMIPP was injected under resting and pain free condition, then data for single photon emission tomography (SPECT) were acquired. The positive regional 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 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.

Objective: To evaluate the diagnostic value of resting myocardial tomographic imaging with 123 I labelled BMIPP ( 123 I-BMIPP SPECT) for exercise-induced angina pectoris by comparison with stress myocardial tomographic imaging with 201 Tl( 201 Tl SPECT). Methods: 123 I-BMIPP SPECT and 201 Tl SPECT were performed in 32 patients with exercise-induced angina pectoris and 12 normal controls. Left ventricle was divided into nine segments and uptake of 201 TL and 123 I-BMIPP was evaluated by four classes score method (defect score, DS). Results: In the patients with angina pectoris, segments of 201 Tl distribution abnormality were more than that of 123 I-BMIPP. Concordant rate between DS of the 20 '1Tl SPECT for detecting coronary artery stenosis were 62%, 92% and 70%, respectively, and 201 Tl SPECT were 84%, 83% and 84%, respectively. Sensitivity of 123 I-BMIPP SPECT was significantly lower than that of 201 Tl SPECT (P 123 I-BMIPP SPECT will be. Conclusions: The results indicated that to a certain extent, resting 123 I-BMIPP SPECT may has practical clinical value for detection of coronary artery stenosis, and determination of stenotic degree in the patients with exercise-induced angina pectoris

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

Angina pectoris (Angina) is a medical condition related to myocardial ischemia. Although acupuncture has been widely accepted as a clinical approach for angina, there is no sufficient evidence of its effectiveness against this syndrome, and its mechanisms have not yet been well elucidated. We develop this protocol to confirm the clinical efficacy of electro-acupuncture on stable angina pectoris by needling on acupoint Neiguan (PC6). Furthermore, we employ high-throughput sequencing technology to investigate the gene expression profiling and determine involvement of histone modifications in the regulation of genes after electro-acupuncture treatment. A randomized, controlled, double-blinded (assessor and patients) trial will be carried out. Sixty participants will be randomly assigned to two acupuncture treatment groups and one control group in a 1:1:1 ratio. Participants in acupuncture groups will receive 12 sessions of electro-acupuncture treatment across 4 weeks, followed by a 12-week randomization period. The acupuncture groups are divided into Neiguan (PC6) on Pericardium Meridian of Hand-jueyin or a non-acupoint. The primary clinical measure of effect is the frequency of angina attacks between these groups for four weeks after randomization. RNAs are extracted from peripheral neutrophils collected from all participants on day 0, day 30, and week 16, and are processed to RNA-Seq. We then investigate profiles of histone modifications by ChIP-Seq, for H3 Lysine 4 (H3K4me) and acetylation of H3 Lysine 27 (H3K27ac), in the presence or absence of acupuncture treatment. This study determines the efficacy and mechanisms of electro-acupuncture on stable angina pectoris. We focus on effectiveness of acupuncture on alleviating symptoms of myocardial ischemia and the gene regulation and the chromatin remodeling marks, including H3K4me1, H3K4me2, and H3K27ac, which could be key factors for regulating gene expressions caused by electro-acupuncture treatment at Neiguan.

Coronary Heart Disease (CHD) occurs to a greater extent in developed than developing countries like Pakistan. Our understanding of risk factors leading to this disease in women, are largely derived from studies carried out on samples obtained from developed countries. Since prevalence of CHD in Pakistan is growing, it seems pertinent to infer risk and protective factors prevalent within the Pakistani women. This case control study investigated the role of psychological, traditional and gender specific risk and protective factors for Angina in a sample of Pakistani women aged between 35-65 years. Female patients admitted with first episode of Angina fulfilling the study inclusion/exclusion criteria were recruited within the first three days of stay in the hospital. One control per case matched on age was recruited. Translated versions of standardized tools: Life Orientation Test (LOT), The Hope Scale, Subjective Happiness Scale and Depression, Anxiety and Stress Scale (DASS) were used to measure the psychological variables. Information on medical conditions like diabetes, hypertension, family history of IHD, presence and absence of menopause and use of oral contraceptive pills was obtained from the participants. Body Mass Index for cases and controls was calculated separately with the help of height and weight recorded for the participants. Multivariate logistic regression analyses revealed that depression, anxiety and stress are risk factors, were as optimism and hope are protective predictors of Angina. 64% and 85% of variance in Angina were attributed to psychological factors. Menopause, diabetes and hypertension are significantly associated with the risk of Angina, explaining 37% and 49% of variance in Angina. The study provides evidence for implementation of gender specific risk assessment and preventive strategies for Angina. The study gives directions for large scale prospective, epidemiological, longitudinal as well as interventional studies, to be tailored

2010-10-01

Full Text Available Abstract Background Rural-to-urban migration in low- and middle-income countries causes an increase in individual cardiovascular risk. Cost-effective interventions at early stages of the natural history of coronary disease such as angina may stem an epidemic of premature coronary deaths in these countries. However, there are few data on the prevalence of angina in developing countries, whilst the understanding the aetiology of angina is complicated by the difficulty in measuring it across differing populations. Methods The PERU MIGRANT study was designed to investigate differences between rural-to-urban migrant and non-migrant groups in specific cardiovascular disease risk factors. Mass-migration seen in Peru from 1980s onwards was largely driven by politically motivated violence resulting in less 'healthy migrant' selection bias. The Rose angina questionnaire was used to record chest pain, which was classified definite, possible and non-exertional. Mental health was measured using the General Health Questionnaire (GHQ-12. Mantel-Haenszel odds ratios (adjusted for age, sex, cardiovascular disease risk factors and mental health were used to assess the risk of chest pain in the migrant and urban groups compared to the rural group, and further to assess the relationship (age and sex-adjusted between risk factors, mental health and chest pain. Results Compared to the urban group, rural dwellers had a greatly increased likelihood of possible/definite angina (multi-adjusted OR 2.82 (1.68- 4.73. Urban and migrant groups had higher levels of risk factors (e.g. smoking - 20.1% urban, 5.5% rural. No diabetes was seen in the rural dwellers who complained of possible/definite angina. Rural dwellers had a higher prevalence of mood disorder and the presence of a mood disorder was associated with possible/definite angina in all three groups, but not consistently with non-exertional chest pain.

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.

In the absence of previous international comparisons, we sought to systematically evaluate, across time and participant age, the sex ratio in angina prevalence in countries that differ widely in the rate of mortality due to myocardial infarction. We searched MEDLINE and EMBASE until February 2006 for healthy population studies published in any language that reported the prevalence of angina (Rose questionnaire) in women and men. We obtained myocardial infarction mortality rates from the World Health Organization. A total of 74 reports of 13,331 angina cases in women and 11,511 cases in men from 31 countries were included. Angina prevalence varied widely across populations, from 0.73% to 14.4% (population weighted mean 6.7%) in women and from 0.76% to 15.1% (population weighted mean 5.7%) in men, and was strongly correlated within populations between the sexes (r=0.80, Pethnic groups than among whites. This sex ratio did not differ significantly by participant's age, the year the survey began, or the sex ratio for mortality due to myocardial infarction. Over time and at different ages, independent of diagnostic and treatment practices, women have a similar or slightly higher prevalence of angina than men across countries with widely differing myocardial infarction mortality rates.

CABG and Preoperative use of Beta-Blockers in Patients with Stable Angina are Associated with Better Cardiovascular Survival

Directory of Open Access Journals (Sweden)

Victor Dayan

Full Text Available Abstract Objective: In contrast to unstable angina, optimal therapy in patients with stable angina is debated. Our aim was to evaluate the outcomes of patients with stable angina scheduled for isolated coronary artery bypass grafts and the effect of preoperative use of beta-blockers. Overall and cardiovascular survivals were our primary outcome. Operative mortality and postoperative complications along with subgroup analysis of diabetic patients were our secondary outcomes. Methods: Retrospective evaluation of patients with stable angina scheduled for isolated coronary artery bypass grafts was included. Pre- and postoperative variables were extracted from the institution database. Survival was obtained from the National Registry. Results: We included 282 patients with stable angina, with a mean age of 65.6±9.5 years. 26.6% were female and 38.7% had diabetes. Three-vessel disease was present in 76.6% of patients. Previous beta-blocker treatment was evident in 69.9% of patients. 10-year overall survival in the whole population was 60.5% (95% confidence interval [CI]: 50.3-70.7%. Operative mortality during the study period was 3.5%. Patients with preoperative use of beta-blocker therapy had better overall survival (9.0 years, 95%CI: 8.6-9.5 than those without treatment (7.9 years, 95%CI: 7.1-8.8 years; P=0.048. Predictors for overall survival were: hypertension, diabetes, and age. Predictors for cardiovascular survival in diabetic patients were: beta-blocker use, gender, and age. Conclusion: Coronary artery bypass grafts surgery in patients with stable angina carries low operative mortality, postoperative complications, and excellent long-term cardiovascular survival. The preoperative use of beta-blockers in diabetic patients is associated with better cardiovascular survival after coronary artery bypass grafts.

Regional myocardial perfusion in patients with atherosclerotic coronary artery disease, at rest and during angina pectoris induced by tachycardia

1977-01-01

We studied regional myocardial perfusion by scintigraphic computer-assisted analysis of initial distribution, washout rates, and residual activity of 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

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

To estimate the cost-effectiveness of ranolazine when added to standard-of-care (SoC) antianginals compared with SoC alone in patients with stable coronary disease experiencing ≥3 attacks/week. An economic model utilising a UK health system perspective, a 1-month cycle-length and a 1-year time horizon. Patients with stable coronary disease experiencing ≥3 attacks/week starting in 1 of 4 angina frequency health states based on Seattle Angina Questionnaire Angina Frequency (SAQAF) scores (100=no; 61-99=monthly; 31-60=weekly; 0-30=daily angina). Ranolazine added to SoC or SoC alone. Patients were allowed to transition between SAQAF states (first cycle only) or death (any cycle) based on probabilities derived from the randomised, controlled Efficacy of Ranolazine in Chronic Angina trial and other studies. Patients not responding to ranolazine in month 1 (not improving ≥1 SAQAF health state) discontinued ranolazine and were assumed to behave like SoC patients. Costs (£2014) and quality-adjusted life-years (QALYs) for patients receiving and not receiving ranolazine. Ranolazine patients lived a mean of 0.701 QALYs at a cost of £5208. Those not receiving ranolazine lived 0.662 QALYs at a cost of £5318. The addition of ranolazine to SoC was therefore a dominant economic strategy. The incremental cost-effectiveness ratio was sensitive to ranolazine cost; exceeding £20,000/QALY when ranolazine's cost was >£203/month. Ranolazine remained a dominant strategy when indirect costs were included and mortality rates were assumed to increase with worsening severity of SAQAF health states. Monte Carlo simulation found ranolazine to be a dominant strategy in ∼71% of 10,000 iterations. Although UK-specific data on ranolazine's efficacy and safety are lacking, our analysis suggest ranolazine added to SoC in patients with weekly or daily angina is likely cost-effective from a UK health system perspective.

Paresthesia-free stimulation such as high frequency and burst have been demonstrated as effective therapies for neuropathic pain. The aim of this meta-analysis was to evaluate the efficacy and safety of conventional spinal cord stimulation (SCS) in the treatment of refractory angina pectoris (RAP). Relevant randomized controlled trials that investigated SCS for patients with RAP were comprehensively searched in Medline, Pubmed, Embase, and Cochrane Library. Five meta-analyses were performed examining the changes in Canadian Cardiovascular Society classes, exercise time, Visual Analog Scale (VAS) scores of pain, Seattle Angina Questionnaire, and nitroglycerin use in RAP patients after SCS therapy. We analyzed standardized mean differences (MD) and 95% confidence intervals (CIs) for each outcome by Review Manager 5.0 and STATA 12.0. A total of 12 randomized controlled trials involving 476 RAP patients were identified. A trend of reduction in the angina frequency (MD=-9.03, 95% CI, -15.70 to -2.36) and nitroglycerin consumption (MD=-0.64, 95% CI, -0.84 to -0.45) could be observed in the SCS group. Compared with the control group, SCS showed benefit on increasing exercise time (MD=0.49, 95% CI, 0.13-0.85) and treatment satisfaction (MD=6.87, 95% CI, 2.07-11.66) with decreased VAS scores of pain (MD=-0.50, 95% CI, -0.81 to -0.20) and disease perception (MD=-8.34, 95% CI, -14.45 to -2.23). However, the result did not reach the significance level in terms of physical limitation (95% CI, -8.75 to 3.38; P=0.39) or angina stability (95% CI, -7.55 to 3.67; P=0.50). The current meta-analysis suggested that SCS was a potential alternative in the treatment of PAP patients. Further investigation for finding the appropriate intensity of stimulation is required before this treatment should be widely recommended and applied.

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.

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.

Patients with symptomatic small vessel coronary artery disease may be inadequate candidates for revascularization procedures. They may suffer from refractory angina, which does not respond to maximal anti-anginal drug therapy. In addition to patients with end stage coronary artery disease and syndrome X, this newly defined group of subjects with an isolated stenosis of a small coronary artery may benefit from electrical neurostimulation. We describe two patients with intractable angina caused by a significant narrowing of a diagonal branch. This treatment modality should be considered as an alternative method for unsatisfactory revascularization procedures.

We performed BMIPP myocardial SPECT and Tl myocardial SPECT in patients with unstable angina (UAP) and stable effort angina (SAP), and compared the results for the two groups. Our subjects were 30 patients with the UAP and 25 patients with the SAP. The early and delayed images of the BMIPP were obtained with patients at rest. The early image of the Tl alone was obtained with patients at rest. We calculated severity score (SS) using the polar map based on SPECT short-axis image on the both myocardial SPECT. And, we calculated % uptake of the responsible coronary lesion and regional washout rate (WR) on myocardial SPECT with BMIPP. On coronary angiogram, no difference in % diameter stenosis was seen between the two groups. On myocardial SPECT with Tl, no difference in the SS was seen between the two groups. However, on myocardial SPECT with BMIPP, the SS was significantly higher score in the UAP group than in the SAP group. And, on myocardial SPECT with BMIPP, the % uptake and the WR were significant lower values in the UAP group than in the SAP group. Even if the two groups have almost the same level of myocardial perfusion disorder, the UAP group may have severer myocardial fatty-acid metabolic disorder than the SAP group, because the defects in BMIPP were significantly severer in the UAP group.

Long-term use of short- and long-acting nitrates in stable angina pectoris.

Science.gov (United States)

Kosmicki, Marek Antoni

2009-05-01

Long-acting nitrates are effective antianginal drugs during initial treatment. However, their therapeutic value is compromised by the rapid development of tolerance during sustained therapy, which means that their clinical efficacy is decreased during long-term use. Sublingual nitroglycerin (NTG), a short-acting nitrate, is suitable for the immediate relief of angina. In patients with stable angina treated with oral long-acting nitrates, NTG maintains its full anti-ischemic effect both after initial oral ingestion and after intermittent long-term oral administration. However, NTG attenuates this effect during continuous treatment, when tolerance to oral nitrates occurs, and this is called cross-tolerance. In stable angina long-acting nitrates are considered third-line therapy because a nitrate-free interval is required to avoid the development of tolerance. Nitrates vary in their potential to induce the development of tolerance. During long-lasting nitrate therapy, except pentaerythritol tetranitrate (PETN), one can observe the development of reactive oxygen species (ROS) inside the muscular cell of a vessel wall, and these bind with nitric oxide (NO). This leads to decreased NO activity, thus, nitrate tolerance. PETN has no tendency to form ROS, and therefore during long-term PETN therapy, there is probably no tolerance or cross-tolerance, as during treatment with other nitrates.

Is refractory angina pectoris a form of chronic pain? A comparison of two patient groups receiving spinal cord stimulation therapy.

2014-03-28

To compare psychological and pain-related characteristics of patients with chronic pain and patients with refractory angina pectoris who had been treated with spinal cord stimulation (SCS) therapy. Twenty-four patients receiving SCS therapy were interviewed. Four psychological variables were assessed using standardised questionnaires for pain catastrophising, health locus of control, anxiety sensitivity, and self-efficacy. Patients also completed the revised version of the Short-Form McGill Pain Questionnaire, the Short-Form Health Survey, and self-reported measures of global perceived effect, pain, functionality, and satisfaction with SCS therapy. Most patients reported improvements in pain, functionality, and improvement overall. Some health locus of control dimensions were significantly higher for the angina group than the chronic pain group, and chronic angina patients reported significantly lower levels of intermittent pain. Virtually all patients reported being satisfied with SCS therapy. Most self-rated psychological and pain-related characteristics were no different between the two groups, which gives some support to the view that refractory angina is a form of chronic pain. The results also add to evidence supporting the use of SCS therapy for refractory angina pectoris; however, differences observed on a few variables may indicate points of focus for the assessment and treatment of such patients.

To assess the safety and efficacy of extracorporeal shockwave myocardial revascularization (ESMR) therapy in treating patients with refractory angina pectoris. A single-arm multicenter prospective trial to assess safety and efficacy of the ESMR therapy in patients with refractory angina (class III/IV angina) was performed. Screening exercise treadmill tests and pharmacological single-photon emission computed tomography (SPECT) were performed for all patients to assess exercise capacity and ischemic burden. Patients were treated with 9 sessions of ESMR to ischemic areas over 9 weeks. Efficacy end points were exercise capacity by using treadmill test as well as ischemic burden on pharmacological SPECT at 4 months after the last ESMR treatment. Safety measures included electrocardiography, echocardiography, troponin, creatine kinase, and brain natriuretic peptide testing, and pain questionnaires. Fifteen patients with medically refractory angina and no revascularization options were enrolled. There was a statistically significant mean increase of 122.3±156.9 seconds (38% increase compared with baseline; P=.01) in exercise treadmill time from baseline (319.8±157.2 seconds) to last follow-up after the ESMR treatment (422.1±183.3 seconds). There was no improvement in the summed stress perfusion scores after pharmacologically induced stress SPECT at 4 months after the last ESMR treatment in comparison to that at screening; however, SPECT summed stress score revealed that untreated areas had greater progression in ischemic burden vs treated areas (3.69±6.2 vs 0.31±4.5; P=.03). There was no significant change in the mean summed echo score from baseline to posttreatment (0.4±5.1; P=.70). The ESMR therapy was performed safely without any adverse events in electrocardiography, echocardiography, troponins, creatine kinase, or brain natriuretic peptide. Pain during the ESMR treatment was minimal (a score of 0.5±1.2 to 1.1±1.2 out of 10). In this multicenter feasibility

Oral Chinese proprietary medicine (CPM) is commonly used to treat angina pectoris, and many relevant systematic reviews/meta-analyses are available. However, these reviews have not been systematically summarized and evaluated. We conducted an overview of these reviews, and explored their methodological and reporting quality to inform both practice and further research. We included systematic reviews/meta-analyses on oral CPM in treating angina until March 2013 by searching PubMed, Embase, the Cochrane Library and four Chinese databases. We extracted data according to a pre-designed form, and assessed the methodological and reporting characteristics of the reviews in terms of AMSTAR and PRISMA respectively. Most of the data analyses were descriptive. 36 systematic reviews/meta-analyses involving over 82,105 participants with angina reviewing 13 kinds of oral CPM were included. The main outcomes assessed in the reviews were surrogate outcomes (34/36, 94.4%), adverse events (31/36, 86.1%), and symptoms (30/36, 83.3%). Six reviews (6/36, 16.7%) drew definitely positive conclusions, while the others suggested potential benefits in the symptoms, electrocardiogram, and adverse events. The overall methodological and reporting quality of the reviews was limited, with many serious flaws such as the lack of review protocol and incomprehensive literature searches. Though many systematic reviews/meta-analyses on oral CPM for angina suggested potential benefits or definitely positive effects, stakeholders should interpret the findings of these reviews with caution, considering the overall limited methodological and reporting quality. We recommend further studies should be appropriately conducted and systematic reviews reported according to PRISMA standard. Copyright © 2014 Elsevier Ltd. All rights reserved.

To evaluate the activity of natural killer cells through their inhibitory and activating receptors and quantity in peripheral blood mononuclear cells extracted from patients with acute myocardial infarction, stable angina pectoris and the controls. 100 patients with myocardial infarction, 100 with stable angina, and 20 healthy volunteers were recruited into the study. 20 randomly chosen people per group were examined for the whole human genome microarray analysis to detect the gene expressions of all 40 inhibitory and activating natural killer cell receptors. Flow cytometry analysis was applied to all 200 patients to measure the quantity of natural killer cells. In myocardial infarction group, the mRNA expressions of six inhibitory receptors KIR2DL2, KIR3DL3, CD94, NKG2A, KLRB1, KLRG1, and eight activating receptors KIR2DS3, KIR2DS5, NKp30, NTB-A, CRACC, CD2, CD7 and CD96 were significantly down-regulated (Pangina patients and the controls. There was no statistical difference in receptor expressions between angina patients and control group. The quantity of natural killer cells was significantly decreased in both infarction and angina patients compared with normal range (Pangina patients showed a quantitative loss and dysfunction of natural killer cells in myocardial infarction patients.

Seasonal peaks in cardiovascular disease incidence have been widely reported, suggesting weather has a role. The aim of our study was to determine the influence of climatic variables on angina pectoris hospital admissions. We correlated the daily number of angina cases admitted to a western Sicilian hospital over a period of 12 years and local weather conditions (temperature, humidity, wind force and direction, precipitation, sunny hours and atmospheric pressure) on a day-to-day basis. A total of 2459 consecutive patients were admitted over the period 1987-1998 (1562 men, 867 women; M/F - 1:8). A seasonal variation was found with a noticeable winter peak. The results of Multivariate Poisson analysis showed a significant association between the daily number of angina hospital admission, temperature, and humidity. Significant incidence relative ratios (95% confidence intervals/measure unit) were, in males, 0.988 (0.980-0.996) (p = 0.004) for minimal temperature, 0.990 (0.984-0.996) (p = 0.001) for maximal humidity, and 1.002 (1.000-1.004) (p = 0.045) for minimal humidity. The corresponding values in females were 0.973 (0.951-0.995) (p < 0.017) for maximal temperature and 1.024 (1.001-1.048) (p = 0.037) for minimal temperature. Environmental temperature and humidity may play an important role in the pathogenesis of angina, although it seems different according to the gender. These data may help to understand the mechanisms that trigger ischemic events and to better organize hospital assistance throughout the year.

Recruitable coronary collaterals may appear when spasm suddenly occludes the coronary artery. We report a patient with variant angina who had visible collateral vessels on a control coronary angiogram, despite the presence of normally appearing coronary arteries. These collaterals disappeared after intracoronary administration of nitroglycerin. These findings suggest that recruitable collateral vessels can remain patent long after spontaneous attacks of angina have resolved, and become visible when there is a pressure difference between two small coronary arteries.

There is a clear association between low serum testosterone and coronary artery disease (CAD) in men. Hypotestosteronaemia is associated with accelerated atherosclerosis and a quarter of men with CAD are biochemically hypogonadal. Amongst those with CAD, hypotestosteronaemia is associated with increased mortality. Testosterone vasodilates coronary arteries, and exogenous testosterone reduces ischaemia. Whether hypotestosteronaemia is a cause or a consequence of CAD remains unanswered. The aim of this prospective observational study was to investigate whether coronary revascularization affected androgen status in men with stable angina pectoris. Twenty five men (mean age 62.7, SD 9.18) with angiographically significant CAD and symptomatic angina underwent full coronary revascularization by percutaneous coronary intervention. Androgen status and symptoms of angina, stress, depression and sexual function were assessed before, and at one and 6 months after the coronary revascularization. All patients underwent complete revascularization which was associated with a significant reduction in angina symptoms and ischaemia. No significant difference was seen in total testosterone (11.33 nmol/L baseline; 12.56, 1 month post; 13.04 at 6 months; p = 0.08). A significant and sustained rise in sex hormone-binding globulin was seen (33.99 nm/L baseline; 36.11 nm/L 1 month post PCI; 37.94 nm/L at 6 months; p = 0.03) Overall, there was no significant alteration in any other marker of androgen status including free testosterone or bioavailable testosterone. There was no change in symptoms of anxiety, depression or sexual function. Coronary revascularization has no sustained effect on androgen status. This supports the hypothesis that hypotestosteronaemia is not a consequence of angina pectoris or myocardial ischaemia. © 2016 American Society of Andrology and European Academy of Andrology.

Medically refractory angina remains a significant health concern despite major advances in revascularization techniques and emerging medical therapies. We aimed to determine the safety and efficacy of extracorporeal shockwave myocardial therapy (ESMT) in managing angina pectoris. A single-arm multicenter prospective study was designed aiming to determine the safety and efficacy of ESMT. Patients of functional Canadian Cardiovascular Society class II-IV, despite stable and optimal medical management, with documented myocardial segments with reversible ischemia and/or hibernation on the basis of echocardiography/single-photon emission computerized tomography (SPECT) were enrolled from 2010 to 2012. A total of 111 patients were enrolled, 33 from Indonesia, 21 from Malaysia, and 57 from Philippines. Patients underwent nine cycles of ESMT over 9 weeks. Patients were followed up for 3-6 months after ESMT treatment. During follow-up, patients were subjected to clinical evaluation, the Seattle Angina Questionnaire, assessment of nitrate intake, the 6-min walk test, echocardiography, and SPECT. The mean age of the population was 62.9±10.9 years. The summed difference score on pharmacologically induced stress SPECT improved from 9.53±17.87 at baseline to 7.77±11.83 at follow-up (P=0.0086). Improvement in the total Seattle Angina Questionnaire score was seen in 83% of patients (Pangina.

A Series of Unfortunate Events: Prinzmetal Angina Culminating in Transmural Infarction in the Setting of Acute Gastrointestinal Hemorrhage

2013-01-01

Full Text Available Prinzmetal angina or vasospastic angina is a clinical phenomenon that is often transient and self-resolving. Clinically it is associated with ST elevations on the electrocardiogram, and initially it may be difficult to differentiate from an acute myocardial infarction. The vasospasm induced in this setting occurs in normal or mildly to moderately diseased vessels and can be triggered by a number of etiologies including smoking, changes in autonomic activity, or drug ingestion. While the ischemia induced is usually transient, myocardial infarction and life-threatening arrhythmias can occur in 25% of cases. We present the case of a 65-year-old female where repetitive intermittent coronary vasospasm culminated in transmural infarction in the setting of gastrointestinal bleeding. This case highlights the mortality associated with prinzmetal angina and the importance of recognizing the underlying etiology.

To evaluate the efficacy and safety of a combination therapy using Chinese medicine (CM) Shenzhu Guanxin Recipe (, SGR) and standard Western medicine treatment (SWMT) in patients with angina pectoris after percutaneous coronary intervention (PCI). Double-blind randomized controlled trial was used in this experimental procedure. One hundred and eighty-seven patients with coronary heart disease receiving SWMT after PCI were randomly assigned to the treatment (SGR) and control (placebo) groups. Outcome measures including angina pectoris score (APS), CM symptom score, and Seattle Angina Questionnaire (SAQ) score were evaluated in 1, 2, 3 and 12 months, and the death rate, restenosis and other emergency treatments were observed. The mixed-effects models were employed for the data analysis. In the treatment group, a larger within-treatment effect size (d=1.74) was found, with a 76.7% reduction in APS from pretreatment to 12-month follow-up assessment compared with the control group (d=0.83, 53.8% symptom reduction); betweentreatment (BT) effect size was d=0.66. CM symptom scores included an 18.3% reduction in the treatment group (d=0.46), and a 16.1% decrease in the control group (d=0.31); d=0.62 for BT effect size. In regard to scores of SAQ, the BT effect size of cognition level of disease was larger in the treatment group (d=0.63), followed by the level of body limitation of activity (d=0.62), condition of angina pectoris attacks (d=0.55), satisfaction level of treatments (d=0.31), and steady state of angina pectoris (d=0.30). Two cardiovascular related deaths and one incidental death were recorded in the control and treatment groups, respectively. No significant difference in any cardiovascular event (including death toll, frequency of cardiovascular hospitalization or emergency room visits) was found between the two groups. The combination therapy of SGR and SWMT is effective and safe in patients with angina pectoris after PCI when compared with SWMT alone.

This paper assessed the evidence of Panax notoginseng preparations in patients suffering from UAP using meta-analysis and systematic review methods. Methods were according to the Cochrane Handbook and analysed using Revman 5.3. A search of PubMed, Cochrane Library, Embase, MEDLINE, Chinese national knowledge infrastructure (CNKI), Vip information database, Wanfang data and Chinese Biomedical Literature Database (SinoMed) was conducted to identify randomized controlled trials (RCTs) of P. notoginseng preparations on UAP regardless of blinding, sex and language. The outcomes include all-cause mortality, cardiac mortality, cardiovascular events, UAP symptoms, improvement of electrocardiogram and adverse events. Eighteen RCTs including 1828 patients were identified. The level of reporting is generally poor. Among 18 studies, 16 studies were prescribed P. notoginseng injections, and two studies were oral P. notoginseng preparations. Reduction of cardiovascular events (RR:0.35;95% CI:0.13 to 0.94), alleviation of angina pectoris symptoms (RR:1.23;95% CI 1.18 to 1.29), improvement of ECG (RR:1.22;95% CI 1.15 to 1.28) and reduced frequency of angina pectoris (MD:-1.48; 95% CI -2.49 to -0.48) were observed. Cardiac mortality and duration of angina pectoris were not statistically significant. Panax notoginseng is beneficial to UAP patients; the results of these reviews may have important implications to clinical work. Copyright © 2017 John Wiley & Sons, Ltd.

The post-ischemic ventricular dysfunction in PRINZMETAL's variant angina: Radionuclide evaluation

International Nuclear Information System (INIS)

Picozzi, R.; Palagi, B.; Baroffio, R.

1987-01-01

We studied by equilibrium radionuclide angiography 15 patients admitted to our coronary care unit because of PRINZMETAL's variant angina. Patients were examined mostly in the absence of symptoms. The incidence of ejection fraction abnormalities was low, while regional wall motion was always impaired at the site corresponding to ST-segment elevation at the time of the anginal attack. In 7 patients who underwent coronary angiography, we found an almost complete agreement between the site of atherosclerotic lesions and that of regional wall motion abnormalities. The patients were re-studied during intravenous perfusion of nitroglycerin: A detectable improvement of regional wall motion was found in 8 of them. We concluded that equilibrium radionuclide angiography appears to be a suitable tool for identifying reliably, in patients affected with PRINZMETAL's variant angina, the regional ventricular dysfunction remaining after the remission of symptoms in the presence of normalized ECG or signs of non-transmural ischemia. Equilibrium radionuclide angiography performed during nitroglycerin perfusion allowed us to evaluate in advance the importance of the vasospastic component and hence the efficacy of pharmacologic treatment.

Stable angina pectoris is experienced as trans-sternal or retro-sternal pressure or pain that may radiate to the left arm, neck or back. Although available evidence relating to its effectiveness and mechanism are weak, traditional Chinese medicine is used as an alternative therapy for stable angina pectoris. We report a protocol of a randomized controlled trial using traditional Chinese medicine to investigate the effectiveness, mechanism and safety for patients with stable angina pectoris. This is a north-east Chinese, multi-center, multi-blinded, placebo-controlled and superiority randomized trail. A total of 240 patients with stable angina pectoris will be randomly assigned to three groups: two treatment groups and a control group. The treatment groups will receive Chinese herbal medicine consisting of Yi-Qi-Jian-Pi and Qu-Tan-Hua-Zhuo granule and Yi-Qi-Jian-Pi and Qu-Tan-Hua-Yu granule, respectively, and conventional medicine. The control group will receive placebo medicine in addition to conventional medicine. All 3 groups will undergo a 12-week treatment and 2-week follow-up. Four visits in sum will be scheduled for each subject: 1 visit each in week 0, week 4, week 12 and week 14. The primary outcomes include: the frequency of angina pectoris attack; the dosage of nitroglycerin; body limited dimension of Seattle Angina Questionnaire. The secondary outcomes include: except for the body limited dimension of SAQ, traditional Chinese medicine pattern questionnaire and so on. Therapeutic mechanism outcomes, safety outcomes and endpoint outcomes will be also assessed. The primary aim of this trial is to develop a standard protocol to utilize high-quality EBM evidence for assessing the effectiveness and safety of SAP via TCM pattern differentiation as well as exploring the efficacy mechanism and regulation with the molecular biology and systems biology.

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 stress imaging (odds ratio 2.8, 95% confidence interval 1.5 to 5.5), and exercise capacity statistic of 0.745 (95% confidence interval 0.70 to 0.79), and an optimized cutpoint of a score of ≤2 included 62% of the subjects and had a negative predictive value of 80%. In conclusion, a simple clinical risk score of 7 characteristics can help differentiate those more or less likely to have CAD among women with angina pectoris and abnormal stress test findings. This tool, if validated, could help to guide testing strategies in women with angina pectoris. Copyright © 2013 Elsevier Inc. All rights reserved.

To evaluate the effectiveness and safety of Xinling Wan on patients with stable angina pectoris, a randomized, double-blinded, placebo parallel-controlled, multicenter clinical trial was conducted. A total of 232 subjects were enrolled and randomly divided into experiment group and placebo group. The experiment group was treated with Xinling Wan (two pills each time, three times daily) for 4 weeks, and the placebo group was treated with placebo. The effectiveness evaluation showed that Xinling Wan could significantly increase the total duration of treadmill exercise among patients with stable angina pectoris. FAS analysis showed that the difference value of the total exercise duration was between experiment group (72.11±139.32) s and placebo group (31.25±108.32) s. Xinling Wan could remarkably increase the total effective rate of angina pectoris symptom score, and the analysis showed that the total effective rate was 78.95% in experiment group and 42.61% in placebo group. The reduction of nitroglycerin dose was (2.45±2.41) tablets in experiment group and (0.50±2.24) tablets in placebo group on the basis of FAS analysis. The decrease of symptom integral was (4.68±3.49) in experiment group and (3.19±3.31) in placebo group based on FAS analysis. Besides, Xinling Wan could decrease the weekly attack time and the duration of angina pectoris. PPS analysis results were similar to those of FAS analysis. In conclusion, Xinling Wan has an obvious therapeutic effect in treating stable angina pectoris, with a good safety and a low incidence of adverse event and adverse reaction in experiment group.

The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.

The possible association between oral infection and chronic inflammation and cardiovascular disease risk has been studied intensively. The present study is designed to determine the strength of association between edentulism and angina pectoris in Mexican adults aged 35 years and older. Using the tools and sampling strategies of the World Health Survey of the World Health Organization, cross-sectional data were collected in Mexico in the National Performance Assessment Survey (probabilistic, multistage, and cluster sampling). Dental information was available for 20 of the 32 states of Mexico. Angina and edentulism are self-reported in this study. Statistical analysis was performed using binary logistic regression adjusting for complex samples. A total of 13,966 participants, representing a population of 29,853,607 individuals, were included. Of the complete study population, 3,052,263 (10.2%) were completely toothless, and 673,810 (2.3%) were diagnosed with angina pectoris. After adjusting for smoking, alcohol consumption, diabetes, body mass index, and sex, the effect of edentulism on angina was modified by age (interaction), being more marked in the younger age group (odds ratio [OR] = exp(2.5597) =12.93) than in the older individuals surveyed (OR = exp(2.5597 + (-0.0334)) =12.51). Additionally, low physical activity (OR = 1.51; 95% confidence interval [CI] = 1.03 to 2.22) and higher socioeconomic status (OR = 1.37; 95% CI = 1.00 to 1.90) were more likely to be associated with angina pectoris. Overall, the results of this study, conducted in a representative sample of Mexican adults, suggest that an association exists between edentulism and angina pectoris. Additional studies are necessary to elucidate the underlying mechanism for this association.

Full Text Available Monocytic angina with superinfection of Prevotella denticola: clinical case Monocytic angina is a clinical sindrome caused by Epstein-Barr virus characterized by fever, pharyngitis, exudative tonsillitis, swollen lymphoglands, splenomegaly and hepatomegaly.The inflamed pharynx and necrotic tonsils of infectious mononucleosis are subject to bacterial superinfection initially or during the course of the illness; the reduced PO2 tension and low oxidation-reduction potential that prevail in a vascular and necrotic tissues favour the growth of anaerobes. In this article we reported the clinical case of a ten years old children, who presented fever and tonsillopharyngitis; he was treated with cefotaxime and piperacillin, he did not improve in health. He was admitted to hospital (Department of Otorhinolaryngology. The patient was treated with aminoglycoside (tobramycin, piperacillin and cortisone; the clinical situation deteriorated. Pus sample was collected from the tonsils and cultured. Isolated strain from culture anaerobic was identified biochemically (Rapid-ID32ANA.The microorganism isolated was: Prevotella denticola (oral anaerobic gram-negative rods; β-lactamase production was tested by using the chromogenic cephalosporin disk test.The susceptibility to antibiotics was performed according to NCCLS recommendations. Prevotella denticola (β-lactamase production was resistant to penicillin, cefoxitin, cefotetan, piperacillin, clindamycin and metronidazole it was susceptible to piperacillin-tazobactam, amoxicillin-clavulanate, ticarcillin-clavulanate, imipenem and chloramphenicol. Children was treated with piperacillin-tazobactam, with rapid symptomatic relief.

Angina pectoris is common in patients with heart failure and reduced ejection fraction (HF-REF) but its relationship with outcomes has not been well defined. This relationship was investigated further in a retrospective analysis of the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA). Four thousand, eight hundred and seventy-eight patients were divided into three categories: no history of angina and no chest pain at baseline (Group A; n = 1240), past history of angina but no chest pain at baseline (Group B; n = 1353) and both a history of angina and chest pain at baseline (Group C; n = 2285). Outcomes were examined using Kaplan-Meier and Cox regression survival analysis. Compared with Group A, Group C had a higher risk of non-fatal myocardial infarction or unstable angina (HR: 2.36, 1.54-3.61; P angina are at an increased risk of acute coronary syndrome and HF hospitalization. Whether these patients would benefit from more aggressive medical therapy or percutaneous revascularization is not known and merits further investigation.

Background Complex angiography lesions and intracoronary thrombus have been identified in unstable angina.Braunwalds categorization has been accepted in the last years.Identifying severe clinical classes class III (angina at rest during the last 48 hours), class C (angina postinfarction) and class c (angina with maximum therapeutic). The main objective of this study was to determine independent associations of Braunwalds classes III, C and c: complex lesions, intracoronary thrombus, total occlusion and distal flux TIMI<3 of the responsible vessel. The secondary objectives were to analyze the angiographic features of the lesion and the responsible vessel. Aprospective study of 300 patients with diagnosed unstable angina, clustered according to Braunwalds clinis classification was done. The angiographic evaluation was performed identifying the responsible lesion and the presence of the complex lesion, intracoronary thrombus, total occlusion and distal flux TIMI<3 of the responsible vessel. A univariate analysis and a multivariate model of binary logistic regression were used. In the 300 patient population, 22 patients with normal coronaries(7.3%) were identified. The responsible lesion was identified in 243 out of the remaining 278 patients (87,4%). Class III was significantly associated with the complex lesion (OR=2.74, IC95%=1,27-5,9) and intracoronary thrombus (OR=2,82 IC95=1,2-6,6). Class C was significantly associated with intracoronary thrombus (OR=3.9),IC95%=1.53-10,0).Class III was and independent predictor for the presence of the complex lesion(OR=1.98, IC 95%=1,01-3,87) and intracoronary thrombus (OR=2,47 IC95%=1,14-5,37). Class C was and independent predictor for the complex lesion (OR=5,05,IC95%=2.25-11,3), infracoronary thrombus (OR=8,04, IC 95%=3,49-18,0), total occlusion (OR=6,49, IC95%=2,67-15,7) and distal flux TIMI<3(OR=3,96,IC 95%=1,87-8,4) There was no significant association between classes III, C and c and the responsible vessel, localization of

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

To assess the efficacy of early invasive strategy for the treatment of Braunwald III-B type unstable angina pectoris. This study included 573 consecutive patients of whom 267 underwent percutaneous coronary intervention (PCI) (312 lesions). The patients were divided into two groups, 95 treated with the early invasive strategy of coronary angiography within 24 hr of admission (Group PCI-I) and the remaining 172 treated with the early conservative strategy of coronary angiography 24 hr after admission (Group PCI-C). No significant differences were noted in the baseline characteristics of the two groups except for ST segment elevation on electrocardiography at presentation, which occurred significantly less frequently in Group PCI-C (36.8% vs 8.1%, p strategy for unstable angina pectoris were almost equivalent to those of the early conservative strategy, despite more frequent ST segmental elevation at admission in Group PCI-I. These findings suggest that the early invasive strategy for unstable angina pectoris may be acceptable even in the current Japanese clinical setting without the use of GP IIb/IIIa receptor antagonist, low molecular weight heparin or clopidogrel.

Objective: To observe changes of plasma neuropeptide Y(NPY) in patients with unstable angina pectoris (UaP), select patients with stable angina pectoris (SAP) and normal subjects as the controls, and recognize their significance. Methods: Immunoradiometric assay was used to measure the plasma NPY levels in 15 UAP patients, 20 SAP patients and 20 normal subjects: Results: It was found that the plasma NPY levels in patients with UAP, SAP and normal subjects were 202.12 +- 35.34, 164.45 +- 24.27 and 156.35 +- 21.84 pg/ml. The NPY levels in UAP patients were significantly higher than that in the others, but down to 159.66 +- 18.75 pg/ml after treatment for 2 weeks. There was a significant difference between pretreatment and post-treatment (P < 0.05). Conclusion: The plasma NPY levels of UAP patients increases significantly during fit. NPY takes part in the process of AP

An unusual case of typical angina which occurred on a long haul flight is presented. This case is notable as this was the index presentation, with no previous symptoms prior to this. Physiological changes at altitude can be marked, and include hypoxia, tachycardia and an increase in cardiac output. These changes were enough to expose underlying angina in our patient. A 68 year old man presented with typical cardiac chest pain on a long haul flight. His symptoms first started 10-15 min after take-off and resolved on landing. This was his index presentation, and there were no similar symptoms in the past. Background history included hypercholesterolaemia and benign prostatic hypertrophy only. He led a rather sedentary lifestyle. A CT coronary angiogram showed significant disease in the proximal left anterior descending artery and proximal right coronary artery. He went on to have a coronary angiogram with invasive physiological measurements, which determined both lesions were physiologically significant. Both arteries were treated with drug eluting stents. Since treatment, he once again embarked on a long haul flight, and was completely asymptomatic. The presentation of symptoms in this individual was rather unusual, but clearly caused by significant coronary artery disease. Potentially his sedentary lifestyle was not enough in day-to-day activities to promote anginal symptoms. When his cardiovascular system was physiologically stressed during flight, brought about by hypoxia, raised sympathetic tone and increased cardiac output, symptoms emerged. In turn, when landing, with atmospheric conditions normalised, physiological stress was removed, and symptoms resolved. Clinically therefore, one should not exclude symptoms that occur with differing physiological states, such as stress and altitude, as they are also potential triggers for myocardial ischaemia, despite absence of day-to-day symptoms.

Full Text Available Refractory angina pectoris is defined as a chronic debilitating condition characterized by the presence of chronic anginal symptoms due to a severe obstructive and/or diffuse coronary artery disease that cannot be controlled by the combination of medical therapy and / or revascularization (percutaneous or surgical. In addition the presence of myocardial ischemia as a cause of the symptoms must have been documented. The coronary sinus Reducer (CSR is a recently introduced percutaneous device to treat patients with severe anginal symptoms refractory to optimal medical therapy and not amenable to conventional revascularization. The purpose of this review is to describe the current evidence from available studies measuring the clinical effect of the CSR implantation on the health and well-being of patients with refractory angina.

Innovative Strategy in Treating Angina Pectoris with Chinese Patent Medicines by Promoting Blood Circulation and Removing Blood Stasis: Experience from Combination Therapy in Chinese Medicine.

2015-01-01

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

In this double-blind randomized placebo-controlled crossover trial, we investigated whether oral sodium nitrate, when added to existing background medication, reduces exertional ischemia in patients with angina. Seventy patients with stable angina, positive electrocardiogram treadmill test, and either angiographic or functional test evidence of significant ischemic heart disease were randomized to receive oral treatment with either placebo or sodium nitrate (600 mg; 7 mmol) for 7 to 10 days, followed by a 2-week washout period before crossing over to the other treatment (n=34 placebo-nitrate, n=36 nitrate-placebo). At baseline and at the end of each treatment, patients underwent modified Bruce electrocardiogram treadmill test, modified Seattle Questionnaire, and subgroups were investigated with dobutamine stress, echocardiogram, and blood tests. The primary outcome was time to 1 mm ST depression on electrocardiogram treadmill test. Compared with placebo, inorganic nitrate treatment tended to increase the primary outcome exercise time to 1 mm ST segment depression (645.6 [603.1, 688.0] seconds versus 661.2 [6183, 704.0] seconds, P =0.10) and significantly increased total exercise time (744.4 [702.4, 786.4] seconds versus 760.9 [719.5, 802.2] seconds, P =0.04; mean [95% confidence interval]). Nitrate treatment robustly increased plasma nitrate (18.3 [15.2, 21.5] versus 297.6 [218.4, 376.8] μmol/L, P nitrate treatment). Other secondary outcomes were not significantly altered by the intervention. Patients on antacid medication appeared to benefit less from nitrate supplementation. Sodium nitrate treatment may confer a modest exercise capacity benefit in patients with chronic angina who are taking other background medication. URL: https://www.clinicaltrials.gov/.

1984-01-01

The purpose of this study was to examine the rest thallium-201 perfusion pattern during angina-free periods in 40 patients with rest angina pectoris secondary to coronary artery disease (greater than or equal to 70% diameter narrowing). Seventeen patients had previous Q wave myocardial infarction. The perfusion defects were considered fixed or reversible, depending on the absence or presence of redistribution in the 4-hour delayed images. There were 40 perfusion defects (26 fixed and 14 reversible) in 27 patients whereas 13 patients had normal scans. Reversible perfusion defects were present in 10 patients (25%). Of the 26 fixed perfusion defects, 17 did not have corresponding Q waves. Occluded vessels (63%) had more perfusion defects than vessels with subtotal occlusion (30%) (p less than 0.01). The perfusion defect size was larger in patients with lower ejection fraction than in patients with higher ejection fraction. We conclude: (1) perfusion defects are common in patients with rest angina and are reversible in 25% of patients indicating reduced regional coronary blood flow; (2) the degree of stenosis affects the presence of perfusion defect; (3) fixed defects may be present without corresponding Q waves; and (4) global left ventricular function is related to the size of perfusion defects

Full Text Available Se presentan los principales resultados de una investigación cuyo propósito es explorar el nivel de posesión de teléfono celular de los estudiantes de primaria, secundaria, preparatoria y universidad de la zona urbana de Ensenada, México. Se analiza el contexto de permisos y prohibiciones del uso del teléfono celular en las escuelas y en qué medida el docente implementa estrategias pedagógicas para su uso. Se desarrolló y aplicó una encuesta a 2 635 estudiantes de los cuatro niveles educativos mencionados. La posesión de teléfono celular presenta una tendencia ascendente según el nivel educativo. Mientras que en primaria el porcentaje de posesión llega a 58%, en universidad alcanza 97%. Por su parte, la tableta encuentra su máximo porcentaje de posesión (46% en el nivel primaria. Llama la atención que la edad en que el estudiante de primaria comienza a usar el teléfono celular es a los 7.8 años. El teléfono celular se ubica en un contexto escolar de prohibición en los niveles primaria y secundaria; sin embargo, en preparatoria y universidad es incipiente su uso con propósito educativo. El potencial pedagógico del teléfono celular es enorme, pero requiere una nueva visión del proceso educativo.

Several preference-based health-related quality of life (HRQoL) instruments have been published and widely used in different populations. However no consensus has emerged regarding the most appropriate instrument in therapeutic area of stable angina. This study compared and validated the psychometric properties of two generic preference-based instruments, the EQ-5D and SF-6D, among Chinese stable angina patients. Convergent validity of the EQ-5D and SF-6D was examined with eight a priori hypotheses from stable angina patients in conjunction with Seattle Angina Questionnaire (SAQ). Responsiveness was compared using the effect size (ES), relative efficiency (RE) and receiver operating characteristic (ROC) curves. Agreement between the EQ-5D and SF-6D was tested using intra-class correlation coefficient (ICC) and Bland-Altman plot. Factors affecting utility difference were explored with multiple linear regression analysis. In 411 patients (mean age 68.08 ± 11.35), mean utility scores (SD) were 0.78 (0.15) for the EQ-5D and 0.68 (0.12) for the SF-6D. Validity was demonstrated by the moderate to strong correlation coefficients (Range: 0.368-0.594, Pstable-angina-specific health status than the EQ-5D (ES: 0.426 to 1.126). RE suggested that the SF-6D (RE: 44.8 to 177.8%) was more efficient than the EQ-5D except for physical function. Poor agreement between them was observed with ICC (0.448, Pstable angina patients. The SF-6D may be a more effective tool with lower ceiling effect and greater sensitivity. Further study is needed to compare other properties, such as reliability and longitudinal response.

Prognostic value of thallium-201 myocardial perfusion imaging in patients with unstable angina who respond to medical treatment

International Nuclear Information System (INIS)

Brown, K.A.

1991-01-01

Although the prognostic value of thallium-201 imaging is well established, its ability to risk stratify patients who present with unstable angina is unclear. Fifty-two consecutive patients admitted with unstable angina who responded to medical treatment and underwent stress thallium-201 imaging within 1 week of discharge were studied. Patients were followed up for 39 +/- 11 months. Cardiac events included cardiac death (n = 3), nonfatal myocardial infarction (n = 4) and admission for unstable angina or revascularization (n = 17). The ability of thallium-201 data (redistribution, fixed defects, normal) to predict cardiac events was compared with clinical data (age, gender, prior myocardial infarction, anginal syndrome, rest and stress electrocardiogram) and cardiac catheterization data using logistic regression. Thallium-201 redistribution was the only significant predictor of cardiac death or nonfatal myocardial infarction (p less than 0.05). The number of myocardial segments with thallium-201 redistribution (p less than 0.0005) and a history of prior myocardial infarction (p less than 0.05) were the only significant predictors of all cardiac events. Cardiac death or nonfatal myocardial infarction occurred more frequently in patients with thallium-201 redistribution (6 [26%] of 23) than in those without redistribution (1 [3%] of 29, p less than 0.05). Similarly, total cardiac events developed more frequently in patients with thallium-201 redistribution (p less than 0.001). Stress thallium-201 imaging has important prognostic value in patients admitted with unstable angina who respond to medical therapy and can identify subgroups at high versus low risk for future cardiac events

Una de las razones es la educación orientada a los exámenes, y como consecuencia, el que se desvíe muy pocos recursos para este aprendizaje informal. La otra razón es que los educadores tienden a pensar en la educación en medios digitales como una serie de operaciones puramente técnicas, lo que podría llevar a los estudiantes de medios digitales a aprender a trabajar sin sentido. Por lo tanto, este estudio diseñó una exhibición de contenidos basada en el modelo de aprendizaje experiencial de Kolb con el fin de enseñar a los estudiantes conceptos de videos stop-motion y técnicas de producción cinematográfica. El experimento diseñado involucró a 247 estudiantes de tercer grado de primaria que fueron agrupados para visitar la exposición experiencial. Los hallazgos sugieren una mejora en los estudiantes de su conocimiento de videos stop-motion. El análisis de los vídeos producidos también muestra que han mejorado su capacidad mediática para representar sus ideas y comunicarse con los demás. A través del análisis de la influencia de la demografía en la prueba de conocimiento, los hallazgos revelan que la exposición experiencial es más efectiva para los estudiantes de primaria femeninos, y que las experiencias anteriores relevantes de los estudiantes no deberían afectar a los conocimientos adquiridos. Teniendo en cuenta estos resultados y observaciones, creemos que la exposición experimental propuesta es una forma prometedora de llevar a cabo la educación en alfabetización digital en las escuelas primarias.

We performed exercise thallium-201 myocardial scintigraphy in 32 patients with angina pectoris to study the incidence of perfusion defects, who had no significant organic stenosis on coronary angiography. None of them had myocardial infarction or cardiomyopathy. Thallium-201 myocardial scintigraphy and 12-lead ECG recording were performed during supine bicycle ergometer exercise. Perfusion defects in thallium-201 scintigrams in SPECT images were assessed during visual analysis by two observers. In the coronary angiograms obtained during intravenous infusion of nitroglycerin, the luminal diameter of 75% stenosis or less in the AHA classification was regarded as an insignificant organic stenosis. Myocardial perfusion defects in the thallium-201 scintigrams were detected in eight (25%) of the 32 patients. Six of these eight patients had variant angina documented during spontaneous attacks with ST elevations in standard 12-lead ECGs. Perfusion defects were demonstrated at the inferior or infero-posterior regions in six patients, one of whom had concomitant anteroseptal defect. The defects were not always accompanied by chest pain. All but one patient demonstrating inferior or inferoposterior defects showed ST depression in leads II, III and aV F on their ECGs, corresponding to inferior wall ischemia. The exception was a case with right bundle branch block. Thus, 25% of the patients with angina pectoris, who had no evidence of significant organic stenosis on their coronary angiograms, exhibited exercise-induced perfusion defects in their thallium-201 scintigrams. Coronary spasms might have caused myocardial ischemia in these patients. (author)

Cabe recordar que a raíz de la promulgación en 1978, se tejieron toda clase de versiones alrededor del significado de la estrategia planteada entonces como un paso fundamental, para un objetivo que parecía inalcanzable. En numerosos debates se hablaba de que se presentaba como una atención elemental de salud, en otros se situaba como el primer contacto de la población con la entidad de salud, en el mejor de los casos se le daba el significado de primera atención, en algunos de atención primordial, en otros de atención básica, no pocos la asimilaban a salud familiar, finalmente cuando se habló en Otawa (Canadá 1986 de la promoción y prevención como fuerzas insustituibles y el Director de la Organización Mundial de la Salud (Mahler 1986 habló de la “reacción favorable frente al fracaso de las acciones anteriores”, tomó fuerza el concepto de atención primaria como el motor insustituible para la promoción y prevención.

Abstract Background: To systematically evaluate the clinical efficacy and safety of Salvianolate injection in the treatment of unstable angina pectoris (UAP). 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 < 0.00001], and the total effectiveness rate of electrocardiogram [RR = 1.26, 95% CI (1.19,1.34), Z = 7.77, P < 0.00001]. In addition, Salvianolate injection can improve the nitroglycerin withdrawal rate and the serum level of NO, decrease high-sensitivity C-reactive protein. 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

Aim Collagens are major cardiac extracellular matrix components, known to be actively remodelled and accumulated during diffuse myocardial fibrosis. We evaluated whether accelerated collagen turnover described by neo-epitope biomarkers reflecting collagen formation and degradation separates patients with diffuse myocardial fibrosis from asymptomatic controls. Methods and results Seventy-one women with angina pectoris without significant coronary artery disease assessed by invasive coronary angiogram were included. Competitive enzyme-linked immunosorbent assays (ELISAs) measuring circulating protein fragments in serum assessed the formation and degradation of collagen type III (Pro-C3, C3M and C3C), IV (P4NP7S and C4M), V (Pro-C5 and C5M) and VI (Pro-C6 and C6M), and degradation of collagen type I (C1M). Serum samples from 32 age-matched asymptomatic women were included as controls. Symptomatic women presented significantly elevated levels of Pro-C6, C3C, C3M, C4M and C8-C ( p angina pectoris, but without significant obstructive coronary artery disease, showed an imbalanced collagen turnover compared to asymptomatic controls. The examined biomarkers are tools to monitor active collagen remodelling in patients with angina pectoris, in risk of developing myocardial fibrosis.

Full Text Available Smoking is a major risk factor in patients with angina pectoris. Interventions that facilitate the rejection of it are an important part of the treatment. Aim. 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.

To explore the effect of ivabradine on angina-related quality of life (QoL) in patients participating in the Study Assessing the Morbidity-Mortality Benefits of the If Inhibitor Ivabradine in Patients with Coronary Artery Disease (SIGNIFY) QoL substudy. QoL was evaluated in a prespecified subgroup of SIGNIFY patients with angina (Canadian Cardiovascular Society class score, ≥ 2 at baseline) using the Seattle Angina Questionnaire and a generic visual analogue scale on health status. Data were available for 4187 patients (2084 ivabradine and 2103 placebo). There were improvements in QoL in both treatment groups. The primary outcome of change in physical limitation score at 12 months was 4.56 points for ivabradine versus 3.40 points for placebo (E, 0.96; 95% confidence interval, -0.14 to 2.05; P=0.085). The ivabradine-placebo difference in physical limitation score was significant at 6 months (P=0.048). At 12 months, the visual analogue scale and the other Seattle Angina Questionnaire dimensions were higher among ivabradine-treated patients, notably angina frequency (Pangina frequency (P=0.034). The effect on QoL was maintained over the study duration, and ivabradine patients had better scores on angina frequency at every visit to 36 months. Treatment with ivabradine did not affect the primary outcome of change in physical limitation score at 12 months. It did produce consistent improvements in other self-reported QoL parameters related to angina pectoris, notably in terms of angina frequency and disease perception. URL: http://www.isrctn.com.

2013-06-01

The aim of the present study was to determine the early and long-term outcomes of coronary artery bypass grafting in patients with acute coronary syndrome and stable angina pectoris. From September 2004 to September 2011, 382 patients with acute coronary syndrome (unstable angina pectoris and non-ST-segment elevation myocardial infarction) and 851 patients with stable angina pectoris underwent first-time isolated coronary artery bypass grafting at our institute. The early and long-term outcomes were compared between the 2 groups. Patients with acute coronary syndrome were older, were more likely to be women, had a smaller body surface area, and were more likely to have left main coronary artery disease. In both groups, bilateral internal thoracic artery grafts were used in approximately 89% of the patients, and off-pump techniques in approximately 97% of the patients. The acute coronary syndrome group had a greater operative death rate (2.6% vs 0.1%) and a greater incidence of low output syndrome (3.1% vs 1.2%) and hemodialysis requirement (2.9% vs 1.1%). Multivariate regression analysis demonstrated that age, acute coronary syndrome, lower ejection fraction, and higher creatinine level before surgery were independent predictors of operative death. However, among the hospital survivors, no differences were seen in freedom from all death (85.4% ± 2.5% vs 87.7% ± 2.0%), cardiac death (97.4% ± 0.9% vs 96.5% ± 0.9%), or major adverse cardiac and cerebrovascular events (78.0% ± 2.9% vs 78.1% ± 2.3%) at 7 years between the patients with acute coronary syndrome and stable angina pectoris. Although acute coronary syndrome is an independent predictor of early mortality in patients undergoing coronary artery bypass grafting, the long-term outcomes after surgery were similar between patients with acute coronary syndrome and stable angina pectoris who survived the early postoperative period.

In patients with ST-segment elevation myocardial infarction (STEMI) pre-infarction angina, pre-procedural TIMI flow and collateral flow to the myocardium supplied by the infarct related artery are suggested to be cardioprotective. We evaluated the effect of these factors on myocardial salvage index (MSI) and infarct size adjusting for area at risk in patients with STEMI treated with primary percutaneous coronary intervention. Cardiac magnetic resonance (CMR) was used to measure myocardial area at risk within 1-7 days and final infarct size 90 ± 21 days after the STEMI in 200 patients. MSI was calculated as (area-at-risk infarct size) / area-at-risk. Patients with pre-infarction angina had a median MSI of 0.80 (IQR 0.67 to 0.86) versus 0.72 (0.61 to 0.80) in those without pre-infarction angina, P = 0.004). In a regression analysis of the infarct size plotted against the area-at-risk there was a strong trend that the line for the pre-infarction angina group was below the one for the non-angina group (P = 0.05). Patients with pre-procedural TIMI flow 0/1, 2 and 3 had a median MSI of (0.69 (IQR 0.59 to 0.76), 0.78 (0.68 to 0.86) and 0.85 (0.77 to 0.91), respectively (PCollateral flow did not change MSI (P = 0.45) nor area-at-risk (P = 0.40) and no significant difference in infarct size adjusted for area at risk (P = 0.25) was observed. Pre-infarction angina increases MSI in patients with STEMI supporting the theory that pre-infarction angina leads to ischemic preconditioning. As opposed to the presence of angiographically visible collateral flow to the infarct area pre-procedural TIMI flow is strongly associated with MSI.

CT coronary angiography in patients with suspected angina due to coronary heart disease (SCOT-HEART): an open-label, parallel-group, multicentre trial.

Science.gov (United States)

2015-06-13

The benefit of CT coronary angiography (CTCA) in patients presenting with stable chest pain has not been systematically studied. We aimed to assess the effect of CTCA on the diagnosis, management, and outcome of patients referred to the cardiology clinic with suspected angina due to coronary heart disease. In this prospective open-label, parallel-group, multicentre trial, we recruited patients aged 18-75 years referred for the assessment of suspected angina due to coronary heart disease from 12 cardiology chest pain clinics across Scotland. We randomly assigned (1:1) participants to standard care plus CTCA or standard care alone. Randomisation was done with a web-based service to ensure allocation concealment. The primary endpoint was certainty of the diagnosis of angina secondary to coronary heart disease at 6 weeks. All analyses were intention to treat, and patients were analysed in the group they were allocated to, irrespective of compliance with scanning. This study is registered with ClinicalTrials.gov, number NCT01149590. Between Nov 18, 2010, and Sept 24, 2014, we randomly assigned 4146 (42%) of 9849 patients who had been referred for assessment of suspected angina due to coronary heart disease. 47% of participants had a baseline clinic diagnosis of coronary heart disease and 36% had angina due to coronary heart disease. At 6 weeks, CTCA reclassified the diagnosis of coronary heart disease in 558 (27%) patients and the diagnosis of angina due to coronary heart disease in 481 (23%) patients (standard care 22 [1%] and 23 [1%]; pheart disease increased (1·09, 1·02-1·17; p=0·0172), the certainty increased (1·79, 1·62-1·96; pheart disease. This changed planned investigations (15% vs 1%; pheart disease, CTCA clarifies the diagnosis, enables targeting of interventions, and might reduce the future risk of myocardial infarction.

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.

2012-04-01

The aim of this study was to evaluate the effects of a smoking cessation education on endothelial function and carboxyhemoglobin levels in smokers with variant angina. A nonequivalent control group pretest-posttest design was used. Participants were 60 male smokers with variant angina admitted to one hospital: the control group (30) between September and December, 2009, and the experimental group (30) between February and May, 2010. Endothelial function, as defined by flow-mediated vasodilation (FMD) of the brachial artery, and serum carboxyhemoglobin (COHb) were determined at baseline and at 3 months after the initiation of education in both groups. Three months after the program, smoking cessation was successful in 22 of the 30 smokers in the experimental group, but only in 4 of 30 smokers in the control group (p<.001). After the education, the experimental group showed a significant increase in FMD, and a significant decreased in serum COHb compared with the control group. The findings indicate that this smoking cessation education program is effective for hospitalized smokers with variant angina.

Refractory angina constitutes a clinical problem. The aim of this study was to assess the safety and the feasibility of transendocardial injection of CD133(+) cells to foster angiogenesis in patients with refractory angina. In this randomized, double-blinded, multicenter controlled trial, eligible patients were treated with granulocyte colony-stimulating factor, underwent an apheresis and electromechanical mapping, and were randomized to receive treatment with CD133(+) cells or no treatment. The primary end point was the safety of transendocardial injection of CD133(+) cells, as measured by the occurrence of major adverse cardiac and cerebrovascular event at 6 months. Secondary end points analyzed the efficacy. Twenty-eight patients were included (n=19 treatment; n=9 control). At 6 months, 1 patient in each group had ventricular fibrillation and 1 patient in each group died. One patient (treatment group) had a cardiac tamponade during mapping. There were no significant differences between groups with respect to efficacy parameters; however, the comparison within groups showed a significant improvement in the number of angina episodes per month (median absolute difference, -8.5 [95% confidence interval, -15.0 to -4.0]) and in angina functional class in the treatment arm but not in the control group. At 6 months, only 1 simple-photon emission computed tomography (SPECT) parameter: summed score improved significantly in the treatment group at rest and at stress (median absolute difference, -1.0 [95% confidence interval, -1.9 to -0.1]) but not in the control arm. Our findings support feasibility and safety of transendocardial injection of CD133(+) cells in patients with refractory angina. The promising clinical results and favorable data observed in SPECT summed score may set up the basis to test the efficacy of cell therapy in a larger randomized trial. © 2014 American Heart Association, Inc.

Selective intra-arterial digital substraction angiography (DSA) is important in the demonstration of the visceral abdominal vessels in angina-abdominalis patients. DSA allows to accurately determine the location of stenoses, vascular occlusions or plaque formations as does conventional angiography; in addition, it provides for simultaneous direct observation which is a major advantage over the conventional technique since suspected lesions can be better focussed in several planes.

We sought to investigate the potential role of elevated levels of thrombopoietin (TPO) in platelet activation during unstable angina (UA). Thrombopoietin is a humoral growth factor that does not induce platelet aggregation per se, but primes platelet activation in response to several agonists. No data concerning its contribution to platelet function abnormalities described in patients with UA are available. We studied 15 patients with UA and, as controls, 15 patients with stable angina (SA) and 15 healthy subjects. We measured TPO and C-reactive protein (CRP), as well as monocyte-platelet binding and the platelet expression of P-selectin and of the TPO receptor, c-Mpl. The priming activity of patient or control plasma on platelet aggregation and monocyte-platelet binding and the role of TPO in this effect also were studied. Patients with UA showed higher circulating TPO levels, as well as increased monocyte-platelet binding, platelet P-selectin expression, and CRP levels, than those with SA and healthy control subjects. The UA patients also showed reduced platelet expression of the TPO receptor, c-Mpl. In vitro, the plasma from UA patients, but not from SA patients or healthy controls, primed platelet aggregation and monocyte-platelet binding, which were both reduced when an inhibitor of TPO was used. Thrombopoietin may enhance platelet activation in the early phases of UA, potentially participating in the pathogenesis of acute coronary syndromes.

Full Text Available Introduction. Abdominal angina, also known as chronic mesenteric ischemia or intestinal angina, is a rare disease caused by intestinal flow reduction due to stenosis or occlusion of mesenteric arteries. A case of successful treatment of a patient with abdominal angina by percutaneous transuliminal angioplasty of high-grade superior mesenteric artery and coeliac trunk stenosis was presented. Case Outline. A 77-year-old male patient was admitted at our Clinic for severe postprandial abdominal pains followed by frequent diarrhoeas. Extensive gastrointestinal investigations were performed and all results were normal. Multislice computerized (MSCT arteriography was indicated which revealed ostial celiac trunk and superior mesenteric artery subocclusion. Percutaneous transluminal angioplasty of the superior mesenteric artery and coeliac trunk was done with two stents implantation. Just a few hours following the intervention, after food ingestion, there were no abdominal pains. Six months later, the patient described a significant feeling of relief after food ingestion and no arduousness at all. Conclusion. High-grade visceral arteries stenoses in patients with intestinal ischemia symptoms can be treated by either surgical procedures or percutaneus transluminal angioplasty. In cases when a low operative risk is anticipated, surgical treatment is recommended due to a better anatomical outcome, while percutaneus angioplasty is advised to elderly patients in whom increased operative risks can be expected.

Objective To assess the population burden of angina pectoris symptoms (APS), self-reported angina and a combination of these, and explore potential ethnic disparity in their patterns. If differences in APS were found between Sami and non-Sami populations, we aimed at evaluating the role of established cardiovascular risk factors as mediating factors. Design Cross-sectional population-based study. Methods A health survey was conducted in 2003–2004 in areas with Sami and non-Sami populations (SAMINOR). The response rate was 60.9%. The total number for the subsequent analysis was 15,206 men and women aged 36–79 years (born 1925–1968). Information concerning lifestyle was collected by 2 self-administrated questionnaires, and clinical examinations provided data on waist circumference, blood pressure and lipid levels. Results This study revealed an excess of APS, self-reported angina and a combination of these in Sami relative to non-Sami women and men. After controlling for age, the odds ratio (OR) for APS was 1.42 (pangina and a combination of these in Sami women and men relative to non-Sami women and men. Established risk factors explained little or none of the ethnic variation in APS. In women, however, less moderate alcohol consumption and leisure-time physical activity in Sami may explain the entire ethnic difference. PMID:24422205

Objective. The randomized controlled trials (RCTs) on Guanxinning injection (GXN) in treating angina pectoris were published only in Chinese and have not been systematically reviewed. This study aims to provide a PRISMA-compliant and internationally accessible systematic review to evaluate the efficacy of GXN in treating angina pectoris. Methods. The RCTs were included according to prespecified eligibility criteria. Meta-analysis was performed to evaluate the symptomatic (SYMPTOMS) and electrocardiographic (ECG) improvements after treatment. Odds ratios (ORs) were used to measure effect sizes. Subgroup analysis, sensitivity analysis, and metaregression were conducted to evaluate the robustness of the results. Results. Sixty-five RCTs published between 2002 and 2012 with 6064 participants were included. Overall ORs comparing GXN with other drugs were 3.32 (95% CI: [2.72, 4.04]) in SYMPTOMS and 2.59 (95% CI: [2.14, 3.15]) in ECG. Subgroup analysis, sensitivity analysis, and metaregression found no statistically significant dependence of overall ORs upon specific study characteristics. Conclusion. This meta-analysis of eligible RCTs provides evidence that GXN is effective in treating angina pectoris. This evidence warrants further RCTs of higher quality, longer follow-up periods, larger sample sizes, and multicentres/multicountries for more extensive subgroup, sensitivity, and metaregression analyses.

Figueras, J.; Cinca, J.; Gutierrez, L.; Segura, R.; Rius, J.

1983-01-01

In 18 consecutive patients without a history of myocardial infarction (MI), prolonged angina pectoris with persistent negative T waves in the precordial leads was associated with a high frequency of in-hospital spontaneous angina (14 of 18, 78%), usually accompanied by S-T segment elevation, and occasionally in-hospital MI (4 of 18, 22%). Angina and MI always involved the electrocardiographic leads with negative T waves. Coronary arteriography, performed in 16 patients, revealed greater than or equal to 90% proximal diameter reduction of the left anterior descending (LAD) coronary artery in 14 patients. No patient had severe narrowing of all 3 major coronary arteries, but the 3 who had 100% LAD occlusion lacked collateral circulation. The ejection fraction was greater than or equal to 50% in 13 patients. Atrial pacing performed in 11 patients at an average rate of 142 beats/min produced a 1.0 mm S-T segment change in only 5 patients (45%), 3 of whom had an associated lactate production. Arterial systemic hypertension induced by methoxamine in 14 patients caused reversal of negative T waves without significant S-T segment shifts or chest pain and failed to elicit lactate extraction abnormalities in each of the 5 patients in whom it was determined. Thus, prolonged angina with persistent negative T waves in the precordial leads is almost invariably associated with a critical and proximal LAD obstruction, severe narrowing of 1 or 2 coronary arteries, and poor or absent collateral vessels

The implementation of new diagnostic and therapeutic technologies is related to expanding financial needs. The escalation of expenses for health protection and simultaneous economic problems has resulted in an interest in the subject of economic assessment. Decision makers in the health sector should have reasonable tools that will allow them to make complex evaluations of the economic suitability of health technologies. Economic analysis should also prove that launching new procedures can save money. Numerous studies indicate that chronic pain and psycho-sociological variables lead to a worse quality of life. Chronic pain issues are a major public health problem, by virtue of the difficulties in efficient therapy and the social costs reflected in incapability of work and disability. Spinal cord stimulation is the most efficacious procedure in the treatment of chronic pain. The aim of the study was to estimate the costs of treatment of 37 patients suffering from refractory angina pectoris and neuropathic pain who underwent SCS surgery between 2002 and 2008 in the Neurosurgery Clinic of the 10th Military Hospital in Bydgoszcz in the period of two years before and two years after spinal cord stimulation. The authors also assessed quality of life, using the SF 36 questionnaire, and degree of pain using VAS. The issue was examined with a cost-benefit analysis. Cost was understood as the expenses made two years before and two years after the SCS procedure. The benefits were health care expenses saved by implementation of the SCS procedure. All the costs included in both alternative treatment techniques in a period of 5 years underwent a discounting procedure. The authors also included the price of the neurostimulator under a sensitivity analysis. To assess the quality of life before and after the SCS procedure, a SF 36 questionnaire was used, and to assess the level of pain before and after the SCS procedure, the VAS scale. The costs of treatment of refractory angina

This study evaluated the sensitivity and the related factors in iodine-123-β-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) scintigraphy to detect stable angina. The subjects were 198 patients with stable angina who underwent BMIPP before percutaneous coronary intervention or coronary bypass graft surgery. Patients with unstable angina, myocardial infarction, congestive heart failure, cardiomyopathy and vasospastic angina were excluded. After investigation of the sensitivity of BMIPP, the patients with single-vessel disease without collateral flow were classified into the normal 12 3 I-BMIPP uptake group (normal group) or decreased 123 I-BMIPP uptake group (decreased group), and various factors were compared between the two groups. Sensitivity was 61% overall, 58% in single-vessel disease, 69% in double-vessel disease, 53% in triple-vessel disease, 43% in only left main vessel disease, and 89% in left main and other vessel disease (NS). In single-vessel disease, the sensitivity was 40% in 75% coronary artery stenosis, 58% in 90% stenosis, 89% in 99% stenosis, and 69% in total occlusion (p=0.003). Comparing the decreased and normal groups, diabetes mellitus was more frequent in the normal group (14.6% vs 39.5%), minimal lumen diameter was smaller (0.75±0.37 vs 0.98±0.49 mm) and lesion length was longer in the decreased group (15.4±4.9 vs 11.6±5.5 mm). Logistic multivariate analysis showed that the independent factors were diabetes mellitus [odds ratio 0.20, 95% confidence interval (CI) 0.04-0.87, p=0.03], minimal lumen diameter (odds ratio 0.10, 95% CI 0.02-0.48, p=0.003) and lesion length (odds ratio 1.12, 95% CI 1.00-1.25, p=0.03). BMIPP is useful in stable angina patients because of the acceptable sensitivity. Diabetes mellitus, minimal lumen diameter and lesion length were independent factors associated with decreased BMIPP uptake. (author)

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.

Objective: To explore the significance of platelet parameters, including mean platelet volume, platelet count and other haematological indices, in patients of acute coronary syndrome. Methods: In this one-year retrospective cross-sectional study in 2010, a total of 631 patients were enrolled at the Cardiovascular Research Institute, Tabriz University of Medical Sciences, Iran, and classified into three groups: myocardial infarction, unstable angina, and Control. Cardiovascular risk factors such as smoking, diabetes mellitus, hyperlipidaemia and hypertension status were compared. Blood samples were collected for the measurement of platelet count, mean platelet volume and other haematological indices, including prothrombin time, partial thromoplastin time, blood group and Rh, haematocrit, haemoglobin, and erythrocyte sedimentation rate. SPSS 18 was used for statistical analysis. Results: Of the total, there were 210 (33.3%; 163 men, 47 women) with myocardial infarction whose mean age was 62.7+-14.2 years; 211 (33.3%; 110 men, 101 women) had unstable angina with a mean age of 63.5+-13.1 years and 210 (33.3%; 117 men, 90 women) health controls with a mean age of 60.6+-12.8 years. The mean platelet volume values of patients in the first two groups were significantly higher than the control group (10.14 +-1.05 fL, 9.82 +- 0.93 fL and 9.34+-1.14 fL, respectively; p< 0.001). The platelet count was detected to be significantly lower in the patients than the controls (207.92+-58.40*109/L, 220.18+-65.81*109/L, 238+-56.10*109/L, respectively, p<0.001). While blood cell count was significantly higher in those with myocardial infarction compared to the unstable angina patients and control group (P<0.001). Differences in mean values of mean platelet volume between the two patient groups was not significant, but mean values of platelet count was statistically significant between these two groups (p<0.04). Conclusion: Mean platelet volume and platelet count may be considered

This study was designed to evaluate the clinical usefulness of delayed exercise images in 99m Tc-tetrofosmin (TF) myocardial SPECT in the diagnosis of vasospastic angina pectoris. We studied 30 patients with vasospastic angina, 10 of 30 patients (group A) had both effort and rest angina, 20 of 30 patients (group B) had rest angina. A 370 MBq of TF was intravenously injected at peak exercise, and initial (EX-I) and delayed exercise (EX-D) images were obtained at 30 min and 180 min after the injection. An additional 740 MBq of TF was intravenously reinjected after EX-D image acquisition, and rest images were obtained 30 min after the reinjection. The left ventricular wall was divided into 9 segments. Regional myocardial uptakes of TF were scored by 4-point defect score (0=normal, 1=mildly reduced, 2=moderately reduced, and 3=severely reduced). Total defect score (TDS) was calculated from the sum of defect scores in 9 segments. Reverse redistribution (RR) was defined as increase of more than 2 in TDS on EX-D images. In group A, 4 of 10 cases (40%) showed decreased uptake on EX-I images, 6 of 10 cases (60%) revealed RR on EX-D images, and none of the patients showed decreased uptake on rest images. In group B, no one showed decreased uptake on EX-I and rest images, 11 of 20 cases (55%) revealed RR on EX-D images. The mean±SD of TDS were 2.9±3.4, 5.1±4.5, 0.5±0.5 on EX-I, EX-D, rest images in group A, and serially 0.4±0.5, 3.3±3.6, 0.4±0.5 in group B. Regional wall motion abnormality was reduced in regions with RR. RR on EX-D images may reflect ischemic damaged but viable myocardium in vasospastic angina. The clinical usefulness of exercise-rest TF imaging in detection of organic coronary artery disease has been well established. Therefore, exercise-rest TF imaging with additional delayed exercise image could evaluate not only organic coronary artery disease but also coronary artery vasospasm. (author)

Calcium antagonists (Ca) have been effective in reducing angina attacks in patients with variant angina. However, there are no reports regarding the effectiveness of Ca on myocardial fatty acid metabolic images in patients with pure coronary spastic angina (CSA). This study sought to examine the correlation between myocardial fatty acid metabolic images and the medical treatment of Ca in patients with pure CSA. This study included 35 consecutive patients (28 men, mean age of 66±10 years) with angiographically confirmed coronary spasm and no fixed stenosis. Long-acting Ca was administered to all 35 patients. Isosorbide dinitrate/nicorandil/another Ca/beta-blocker were administered when chest pain was not controlled. Using an iodinated fatty acid analogue, 15-(p-[iodine-123]iodophenyl)-3-(R,S)methylpentadecanoic acid (BMIPP), myocardial scintigraphies with intravenous adenosine triphosphate infusion were performed before cardiac catheterization and 12 mo after medical therapy. According to the medical control states, these 35 patients were classified into 3 groups; response (disappearance of angina attacks, 12 pts, 60±11 years), partial response (angina attacks <4/mo, 12 pts, 67±10 years), and no response to therapy (angina attacks ≥4/mo, 11 pts, 71±6 years). Reduced BMIPP uptake was observed in 24 (69%) of 35 patients before the treatment. Reduced BMIPP uptake was also found in 18 patients (51%) after 12 mo. Normal BMIPP uptake after 12 mo therapy was observed in about half (response: 42%, partial response: 58%, no response: 45%) of patients among the 3 groups. There was no difference regarding the value of washout rate (WOR) (response; 10±7 (before), 14±8% (12 mo)), partial response; 11±7, 10±5%, no response; 13±9, 14±8%) among the 3 groups. The defect scores of BMIPP in the three groups were not different during at least one year medical therapy. No difference regarding the distribution of other medical therapies (angiotensin converting enzyme

Objective: To evaluate the efficacies of percutaneous coronary intervention (PCI) and drug treatment in patients with unstable angina (UAP). Methods: 248 patients with UAP were divided into two groups: conservative group of 123 patients who received antiplatelet, anticoagulant and antianginal therapies only and invasive group of 125 patients who underwent additional PCI 4.4 days after admission. The occurrence of death, AMI, recurrent angina, readmission were assessed during the first hospitalization year. Results: There was no difference in the incidence of composite endpoint of death or AMI between the two groups during the hospitalization (0.8 % vs 1.6 %, P > 0.05 ), but hospitalization duration was shorter in the invasive group than in the conservative group (10.3 ± 5.6 days vs 14.6 ± 10.7 days, P < 0.01 ). In duration of one year, the incidence of AMI (2.4% vs 8.9%, P<0.03), death (1.6% vs 6.5%, P<0.05), composite endpoint of death or AMI (4.0 % vs 13.0 % P < 0.02), recurrent angina pectoris (26.4 % vs 48.7, P <0.001), CABG (1.6% vs 10.5%, P<0.01) and readmission (24.8% vs 45.5%, P<0.01) were also lower in the invasive group than in the conservative group. Survival rate free of composite death or AMI for 1 year was higher in the invasive group than in the conservative group(96.0 % vs 86.9 %, P < 0.02). There was a definite benefit of the invasive treatment in reducing the risk of composite endpoint of death or AMI in patients with chest pain at rest, troponin T positive and three vessel diseases. Old age, three vessel diseases, LAD disease, lower LVEF, ST-segment depression, diabetes and hypertension were the independent factors associated with composite of death or AMI. Conclusions: In patients with UAP, PCI associated with routine antiplatelet, anticoagulant and antiischemic treatment significantly decreases the incidence of adverse cardiac events and improves the survival rate in one year. Such beneficial effects can be more obvious for high-risk patients

In order to evaluate the effects of acupuncture in moderate, stable angina pectoris, 49 patients were randomized to either genuine or sham acupuncture. In sham acupuncture needles were inserted into points within the same spinal segment as in genuine acupuncture, but outside the Chinese meridian...... system. The effect was evaluated from exercise tests, anginal attack rate and nitroglycerin consumption. There were no significant differences between the effects of genuine and sham acupuncture either on exercise test variables or on subjective variables. In patients receiving genuine acupuncture...... there was a significant increase in exercise tolerance (median 9%) and in delay of onset to pain (median 10%). No significant changes were observed in patients receiving sham acupuncture. Within both groups there was a median reduction of 50% in anginal attack rate and nitroglycerin consumption...

Full Text Available The article presents the results of the study of the comparative efficacy of the protocol for angina pectoris medication and combined therapy with the use of ω-3 PUFA and magnetotherapy on the dynamics of the frequency of anginal attacks of patients with stable angina. It was found that the use of ώ-3 PUFA and MT in therapy allows a significantly higher and further reduction in the frequency of attacks compared with standard therapy, and this effect is largely due to the influence of MT and to a lesser extent - the effect of omega-3 polyunsaturated fatty acids.

Myocardial scintigraphy with thallium-201 is a new, non-invasive diagnostic method by means of which on special indications ischaemic heart diseases may be demonstrated. The case history is described of a man with hypertrophic cardiomyopathy and angina pectoris. The electrocardiogram at rest was affected by the cardiomyopathy to such a degree that the interpretation of the ST-T segment during effort was not reliable. Scintigraphy revealed transient ischaemia. A bypass operation was carried out and post-operatively, the improved myocardial perfusion could be confirmed by myocardial scintigraphy. (Auth.)

Enhanced External Counterpulsation Is an Effective Treatment for Depression in Patients With Refractory Angina Pectoris

Science.gov (United States)

Søgaard, Hans Jørgen

2015-01-01

Objective: To examine the effect of enhanced external counterpulsation (EECP) on depression in patients with refractory angina pectoris (Canadian Cardiovascular Society class 2–4). Method: The study was a prospective observational investigation with a 2-month control period preceding the EECP therapy (to minimize a possible effect of the regression-toward-the-mean phenomenon). The patients were examined 2 months before and just before EECP and just after, 3 months after, and 12 months after EECP. Depression was assessed using the Major Depression Inventory and the ICD-10. During EECP, 3 sets of cuffs were fastened around the lower extremities and were inflated sequentially to a pressure of 260 mm Hg in each diastole for 60 minutes 5 days a week for 7 weeks (35 sessions). The study was conducted at a regional hospital in Denmark from May 2006 to January 2011. Results: Fifty patients with angina pectoris and an abnormal coronary angiography, with no possibility for revascularization, were included (72% men, mean age of 63 years) between May 2006 and January 2011. The prevalence of depression before EECP was 18%, just after was 2%, 3 months after was 2%, and 12 months after was 4% (P = .013). The depressive state was more severe at a lower age (P = .016). No significant predictors of effect of EECP on depression were found (P > .05), and no association was detected between decline in depressive state and chest pain (P > .05). Conclusions: The study indicates that EECP is an effective treatment for depression in patients with refractory angina pectoris, that depression is more severe in younger patients, and that the effect of EECP on depression is not related to the effect on chest pain.

Data comparing the clinical benefits of medical treatment with those of percutaneous coronary intervention (PCI) in an elderly population with angina pectoris are limited. Therefore, we evaluated the efficacy of elective PCI versus optimal medical treatment (OMT) in elderly patients (between 75 and 84 years old) with angina pectoris. One hundred seventy-seven patients with significant coronary artery stenosis were randomly assigned to either the PCI group (n=90) or the OMT group (n=87). The primary outcome was a composite of major adverse events in the 1-year follow-up period that included cardiovascular death, non-fatal myocardial infarction, coronary revascularization, and stroke. Major adverse events occurred in 5 patients (5.6%) of the PCI group and in 17 patents (19.5%) of the OMT group (p=0.015). There were no significant differences between the PCI group and the OMT group in cardiac death [hazard ratio (HR) for the PCI group 0.454; 95% confidence interval (CI) 0.041-5.019, p=0.520], myocardial infarction (HR 0.399; 95% CI 0.039-4.050, p=0.437), or stroke (HR 0.919; 95% CI 0.057-14.709, p=0.952). However, the PCI group showed a significant preventive effect of the composite of major adverse events (HR 0.288; 95% CI 0.106-0.785, p=0.015) and against the need for coronary revascularization (HR 0.157; 95% CI 0.035-0.703, p=0.016). Elective PCI reduced major adverse events and was found to be an effective treatment modality in elderly patients with angina pectoris and significant coronary artery stenosis, compared to OMT.

Full Text Available Antecedentes: El trastorno depresivo mayor (TDM es una enfermedad frecuente en la población general y una de las principales causas de discapacidad en el mundo. La distinción entre los cambios que normalmente ocurren en el estado del ánimo y aquellos que están presentes en el espectro de los trastornos depresivos no es una tarea fácil, por esta razón se han propuestos varios mecanismos e instrumentos para mejorar la detección de este trastornos en la consulta de atención primaria. Objetivos: Evaluar si la detección sistemática rutinaria con instrumentos de tamizaje, con o sin sistemas de seguimiento y manejo integrado, es más efectiva que la atención usual en identificar pacientes con depresión, facilitar su tratamiento, y mejorar los resultados clínicos, a nivel de la atención primaria. Material y Métodos: Para determinar la utilidad del tamizaje sistemático para depresión a nivel de atención primaria, se llevó a cabo una búsqueda de estudios de casos y controles, cohortes y controlados aleatorizados, revisiones sistemáticas, y meta-análisis, en las bases de datos MEDLINE, Base de datos de revisiones sistemáticas Cochrane, Registro central de estudios controlados Cochrane, PsycINFO, y EMBASE, desde enero de 1976 hasta el 30 de abril de 2013. Resultados: La evidencia existente mostró que muchos casos de depresión no son detectados. Los médicos de atención primaria (MAP logran tasas de detección del trastorno depresivo entre el 30% y 40% (rango 7-70%, sin utilizar herramientas adicionales para el diagnóstico como las escalas de una, dos y tres preguntas. Los pacientes con los cuadros menos severos y más jóvenes son los menos detectados. Conclusiones: La evidencia encontrada muestra que el tamizaje para depresión a nivel de atención primaria con retroalimentación del resultado puede incrementar el reconocimiento del trastorno por parte del MAP. Sin embargo, el efecto de la retroalimentación sobre el tratamiento

ST-T isointegral analysis of exercise stress body surface mapping for identifying ischemic areas in patients with angina pectoris

International Nuclear Information System (INIS)

Nakajima, T.; Kawakubo, K.; Toda, I.; Mashima, S.; Ohtake, T.; Iio, M.; Sugimoto, T.

1988-01-01

ST-T isointegral analysis of body surface mapping was used in an attempt to localize ischemic areas on exercise tests. In 28 patients with angina pectoris and 10 healthy subjects, body surface potential was recorded with 87 leads, and ST isopotential and ST-T isointegral maps were constructed. In all 10 healthy subjects, the basic pattern of the ST-T isointegral map showed no significant change after exercise. In 23 of 28 patients with angina pectoris (82%), alterations in the ST-T isointegral map after exercise were observed. They were divided into four types (anterior, inferoposterior, lateral, and global) according to the distribution of negative values, which were well correlated with the extent of ischemic area determined by thallium myocardial scintigraphy and coronary angiography. The postexercise ST-T isointegral map was normalized after administration of nitroglycerin in four of five patients. In five patients (18%) who did not show abnormalities on the postexercise ST-T isointegral map, the magnitude of maximal ST depression was significantly smaller than that observed in the other 23 patients with angina pectoris (0.14 vs 0.23 mV on the average, p less than 0.05). It was concluded that the exercise test with ST-T isointegral mapping is a new method for noninvasive detection of location and severity of ischemic regions

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.

Nicorandil significantly reducted the incidence of major coronary events in patients with stable angina in a long-term trial, although there are few reports on its short-term efficacy in the treatment and prevention of angina symptoms. We performed a meta-analysis of the short-term efficacy of nicorandil compared with antianginal drugs for stable angina. We selected 20 reports (vs. β-blockers, n=6; vs. nitrates, n=6; vs. calcium antagonists, n=8) of prospective controlled trials from MEDLINE, the Cochrane Library, and Japana Centra Revuo Medicina. The trials were short in duration (median 5 weeks). We combined the results using odds ratios (OR) for discrete data and weighted mean differences (WMD) for continuous data. Compared with antianginal drugs, nicorandil did not show significant reduction of angina episodes per week (vs. β-blockers, -1.50 [95% confidence interval (CI): -4.09, 1.09]; vs. nitrates, 0.22 [95% CI: -1.22, 1.65]; vs. calcium antagonists, -0.23 [95% CI: -1.37, 0.90]). Furthermore, there were no significant differences in time to ischemia (total exercise duration, time to 1-mm ST depression, time to onset of pain). Although the total numbers of adverse events with each antianginal drug were similar, heart rate and blood pressure were significantly decreased by calcium antagonists but not changed by nicorandil (8.09 [95% CI: 3.20, 12.98] and 8.64 [95% CI: 3.28, 13.99], respectively). Thus this study suggests that short-term therapy with nicorandil is as effective as standard therapy and that nicorandil can also be used as a first-line agent in patients with stable angina.

To evaluate the feasibility of a double-acquisition coronary CT angiography (CCTA) protocol in the presence and absence of an intravenous (IV) vasodilator infusion for detecting vasospastic angina. Twenty patients with a high clinical probability of vasospastic angina were enrolled. All subjects underwent baseline CCTA without a vasodilator in the early morning followed by a catheterized coronary angiography with ergonovine provocation test. Within 3 days, all subjects underwent repeat CCTA during a continuous IV infusion of nitrate. Vasospastic angina as detected by CCTA was defined as significant stenosis (≥50 %) with negative remodelling without definite plaques or diffuse small diameter (<2 mm) of a major coronary artery with a beaded appearance on baseline CT that completely dilated on IV nitrate CT. The CCTA results were compared to the catheterized ergonovine provocation test as the reference standard. Among 20 patients, the catheterized ergonovine provocation test detected vasospasm in 15 patients. The sensitivity, specificity, positive predictive value and negative predictive value of CCTA in a per-patient-based analysis were 73, 100, 100 and 56 %, respectively. Double-acquisition CCTA in the presence and absence of IV infusion of nitrate allows noninvasive detection of vasospastic angina with moderate sensitivity and high specificity. (orig.)

Hyperthyroidism is associated with an increase in myocardial oxygen consumption that, due to an imbalance of oxygen demand and supply, can cause angina. However, subclinical hyperthyroidism rarely presents as chest pain in the resting state. Herein, we present a case of subclinical hyperthyroidism involving a 58-year-old male who complained of frequent chest tightness and typical electrocardiographic changes while in a resting state. Coronary angiography showed no significant lesion. Laboratory data showed that the patient suffered from hyperthyroidism, for which he was successfully treated with anti-thyroid agents. We are reminded that typical chest pain might be the first symptom of hyperthyroidism.

In addition, the presence of myocardial ischemia as a cause of the symptoms must have been documented. The coronary sinus reducer (CSR) is a recently introduced percutaneous device to treat patients with severe anginal symptoms refractory to optimal medical therapy and not amenable to conventional revascularization. The purpose of this review is to describe the current evidence from available studies measuring the clinical effect of the CSR implantation on the health and well-being of patients with refractory angina.

Full Text Available Fundamentos: Las agresiones de usuarios a los profesionales de Atención Primaria se han incrementado en los últimos años. No existen estudios previos en atención primaria que abarquen toda una Comunidad Autónoma y todas las categorías profesionales. El objetivo del estudio fue caracterizar la violencia en atención primaria de la Comunidad de Madrid. Métodos: Estudio descriptivo multicéntrico de las notificaciones de agresiones sufridas por los profesionales de Atención Primaria de la Comunidad de Madrid. Las variables del estudio incluyeron características sociodemográficas de las personas agresoras y de las agredidas, el tipo de agresión, sus causas y consecuencias. Se calcularon la mediana, el rango intercuartílico y las frecuencias. Se realizó un análisis de regresión logística calculando las OR y sus IC95%. Resultados: En el periodo de estudio se notificaron 1.157 agresiones, el 53,07% las notificaron médicos. En el 4,7% de los casos hubo agresión física. El principal motivo fue la disconformidad con la atención recibida (36,1%. El personal no sanitario mostró menos riesgo de ser agredido físicamente que el personal sanitario (OR: 0,38; IC95%: 0,17-0,86. La agresión fue cometida por un hombre en el 56,8% de los casos y del grupo de edad entre 31-40 años en el 26,8%. La persona agredida fue mujer en el 84% de los casos, con una edad comprendida entre 45-60 años. El 10% de los profesionales notificaron las agresiones y el 5,9% la denunció. Conclusiones: El riesgo de sufrir agresión es mayor en el personal sanitario, especialmente médicos. Tanto en el perfil de las personas agresoras como de las agredidas se detectaron diferencias significativas por sexo y edad.

Full Text Available Ludwig's angina is potentially lethal, rapidly spreading cellulitis of the floor of mouth and neck. The anticipated difficult airway becomes even more challenging when it occurs in children. In children, the larynx is positioned relatively higher in the neck, and one does not have the option for blind nasal intubation or awake fiberoptic, which otherwise is the technique of choice in adult patients. We present the clinical course of 16 children and highlight various problems encountered during the anesthetic management of six children who required emergency surgical drainage under general anesthesia.

1991-01-01

Full Text Available In a five year period 238 of 594 esophageal manometric studies performed in the authors’ laboratory were done on patients whose major reason for referral was noncardiac angina-like chest pain. Standard eophageal manometry was performed followed by an acid-antacid perfusion period (Bernstein test and then subcutaneous bethanechol (80 μg/kg to a maximum of 5 mg was adminstered. Baseline manometry was normal in 38% of patients and was diagnostic of ‘nutcracker’ esophagus, nonspecific esophageal motility disorder, diffuse esophageal spasm and isolated hypertensive lower esophageal sphincter in 24%, 19%, 16% and 3% of patients, respectively. Ninety-six of 238 patients (40% experienced reproduction of their presenting angina-like chest pain during acid perfusion. In 80% of these patients there were associated esophageal motor abnormal ilies induced by the acid perfusion. Thirty-six of 212 (17% experienced pain reproduction following the injection of bethanechol; however, 16 of these had already had their presenting chest pain reproduced during the acid perfusion study. In two-thirds of the patients with pain reproduction following bechanechol there was an associated bethanechol-induced esophageal motility disorder. Overall 49% of patients had their pain reproduced during provocative testing. The acid perfusion test reproduced the pain much more frequently than bethanechol simulation. This study reaffirms the value of esophageal manometry and provocative testing in this group of patients.

La criptococosis cutánea es una micosis propia de pacientes inmunodeprimidos, sobre todo aquellos con infección por el virusde la inmunodeficiencia humana (VIH). Sin embargo, existen casos infrecuentes de criptococosis cutánea en pacientes inmunocompetentes, que suelen simular otras dermatosis, lo que retrasa su diagnóstico y tratamiento. Presentamos el caso de un varón pluripatológico de 79 años, con úlceras dolorosas en dorso de mano derecha que no respondían a tratamientos tópicos. A través del estudio histopatológico y micológico se alcanzó el diagnóstico de criptococosis cutánea primaria, lográndose la remisión de las lesiones tras 6 meses de tratamiento con fluconazol.

To determine the effect of the introduction of casemix funding on resource utilisation and clinical outcomes in patients admitted to hospital with suspected unstable angina. A prospective cohort study with a 6-month follow-up. A suburban community hospital in Melbourne, Victoria. 336 consecutive patients admitted to the coronary care unit with suspected unstable angina before (156) and after (180) the introduction of casemix funding. Introduction of casemix funding in July 1993. Indices of resource utilisation: length of stay in hospital, length of stay in the coronary care unit, and total cost of investigations (pathology and radiology). Rates of serious cardiac events during hospital stay and after discharge. Readmissions within 28 days and 6 months of discharge. After the introduction of casemix funding there was a 1% increase in duration of hospital stay and a 5% increase in time spent in the coronary care unit, but neither of these increases was statistically significant. However, there was a significant reduction in total cost of investigations (39% decrease; 95% confidence interval, 14%-70%; P Casemix funding had no effect on short term clinical outcomes but resulted in significantly reduced investigation costs.

1986-04-01

In 1981, a large, double-blind, randomized trial was started in The Netherlands to evaluate the therapeutic effects of nifedipine and/or metoprolol in patients with unstable angina. This study has been called the Holland Interuniversity Nifedipine/metoprolol Trial (HINT) and required several hundred patients to establish potential therapeutic effects. From December 1982 to January 1984 the effects of nifedipine on left ventricular (LV) performance in a subgroup of 52 HINT patients were studied using radionuclide techniques. All patients (23 on nifedipine, 29 controls) underwent thallium-201 scintigraphy or radionuclide angiography just before and 48 h after the start of experimental medication. The radionuclide angiographic studies were also performed at 1 and 4 h after treatment. Nifedipine did not influence the incidence of disapperance of perfusion defects on the 48-h thallium images. No significant differences in overall LV ejections fraction (EF) were seen at any time between nifedipine-treated patients and controls. However, paired observations in 37 patients showed improvement of LVEF after 48 h in 8 patients on nifedipine and in only 1 control patient. Scintigraphic measurements on admission were not related to clinical outcome after 48 h. Concomitant administration of metoprolol did not influence LVEF in either group. It is concluded that nifedipine improves LVEF after 48 h in a subset of patients with unstable angina without affecting myocardial perfusion. This finding indicates that nifedipine has a predominant effect on afterload reduction in patients with unstable angina. Also, early scintigraphic measurements had no significant predictive value for subsequent cardiac events.

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

Full Text Available Este artículo intenta indagar en las ideas de los docentes de educación primaria sobre los modelos familiares que se apartan del tradicional de familia nuclear. Se trabajó con 60 docentes de Montevideo y zona metropolitana respondiendo el Cuestionario de Ideas de los Docentes sobre Diversidad Familiar –CIDF– (Morgado, Jiménez-Lagares & González, 2009. Los datos obtenidos refieren que los docentes no mantienen una visión homogénea de los distintos tipos de hogares. Las familias adoptivas, las de progenitores divorciados y las monoparentales bajo responsabilidad de madres tuvieron mejor aceptación entre los docentes que las homoparentales o las encabezadas en solitario por un padre. Los ítems relativos a familias homoparentales fueron respondidos por menos personas. Los docentes con formación de posgrado se mostraron más tolerantes y flexibles ante la diversidad familiar. Se discuten estos resultados a la luz de las necesarias adaptaciones en la educación primaria con respecto a la diversidad de familias que allí asisten.

2005-01-01

Full Text Available Hyperthyroidism is associated with an increase in myocardial oxygen consumption that, due to an imbalance of oxygen demand and supply, can cause angina. However, subclinical hyperthyroidism rarely presents as chest pain in the resting state. Herein, we present a case of subclinical hyperthyroidism involving a 58-year-old male who complained of frequent chest tightness and typical electrocardiographic changes while in a resting state. Coronary angiography showed no significant lesion. Laboratory data showed that the patient suffered from hyperthyroidism, for which he was successfully treated with anti-thyroid agents. We are reminded that typical chest pain might be the first symptom of hyperthyroidism.

Pretende responder a la cuestión de si las directrices que rigen las actuaciones en torno a la lectura de las bibliotecas escolares de Bizkaia, en el País Vasco, son convenientes y fructíferas. Con este objetivo, primero se ha realizado un análisis detallado de los hábitos lectores y las percepciones sobre la importancia de la lectura que tienen los escolares y sobre quién los induce. Posteriormente hemos elaborado un estudio diagnóstico de las bibliotecas de centros de Educación Primaria, analizando su trabajo como agente lector y su integración e implicación con la comunidad educativa. Y finalmente se ha establecido la relación de los dos análisis anteriores para ver hasta qué punto la existencia de una biblioteca escolar favorece o no los hábitos lectores, concluyendo, por una parte, que la actitud y el estímulo familiar son elementos básicos para favorecer los hábitos lectores y, por otra, que la mera presencia de una biblioteca escolar en el centro no es suficiente para mejorar hábitos o valoración de la lectura, sino que la clave está en el tipo de biblioteca que trabaja con los escolares.

Full Text Available Background: Episodes experienced by angina patients are potentially frightening and life threatening. Angina patients lack awareness regarding Percutaneous Coronary Intervention (PCI as a prognostic benefit. Aim and Objectives: To identify the information needs in relation to physical activity among angina patients before PCI at a private hospital in Penang, Malaysia. Material and Methods: A cross-sectional study was conducted from April to July 2016; 150 respondents who fulfilled the inclusion criteria were recruited. A 16-item questionnaire related to physical limitations was adapted and modified from Seattle Angina Questionnaire (SAQ. Results: The findings reported that majority of respondents (103; 69% possessed more than one co-morbidity, while 47respondents (31% single co-morbidity. Those with secondary level education showed (M=15.98, SD±6.14 while tertiary level education reported (M=16.61, SD±6.11, with no significant difference (t= -0.623, p= 0.534 between respondents' education level and physical activity. In terms of occupation, employed (M=15.58, SD±6.42 and unemployed (M=17.31, SD±5.52 also reported significant difference with (t= -1.70, p= 0.04. There was likewise a significant difference between respondents with single co-morbidity (M=18.09, SD±6.88 and multiple co-morbidity (M=15.46, SD± 5.58 with (t= 2.475, p= 0.01.However, there was no significant difference between respondents with previous admission and physical activity (t= 0.868, p= 0.387, as well as respondents' age group with physical activity (t=-0.675, p= 0.501.Conclusion: In conclusion, respondents' information needs regarding PCI are significantly associated with occupation and co-morbidity towards physical activity before PCI. Age, educational level and previous admission did not have any effect on respondents' physical activity before PCI.

Full Text Available Abstract Background Patients with refractory angina pectoris in end-stage coronary artery disease represent a severe condition with a higher reduction of life-expectancy and quality of life as compared to patients with stable coronary artery disease. It was the purpose of this study to invasively re-evaluate highly symptomatic patients with formerly diagnosed refractory angina pectoris in end-stage coronary artery disease for feasible options of myocardial revascularization. Methods Thirty-four Patients formerly characterized as having end stage coronary artery disease with refractory angina pectoris were retrospectively followed for coronary interventions. Results Of those 34 patients 21 (61.8% were eventually revascularized with percutaneous interventional revascularization (PCI. Due to complex coronary morphology (angulation, chronic total occlusion PCI demanded an above-average amount of time (66 ± 42 minutes, range 25–206 minutes and materials (contrast media 247 ± 209 ml, range 50–750 ml; PCI guiding wires 2.0 ± 1.4, range 1–6 wires. Of PCI patients 7 (33.3% showed a new lesion as a sign of progression of atherosclerosis. Clinical success rate with a reduction to angina class II or lower was 71.4% at 30 days. Surgery was performed in a total of8 (23.5% patients with a clinical success rate of 62.5%. Based on an intention-to-treat 2 patients of originally 8 (25% demonstrated clinical success. Mortality during follow-up (1–18 months was 4.8% in patients who underwent PCI, 25% in patients treated surgically and 25% in those only treated medically. Conclusion The majority of patients with end-stage coronary artery disease can be treated effectively with conventional invasive treatment modalities. Therefore even though it is challenging and demanding PCI should be considered as a first choice before experimental interventions are considered.

2013-01-01

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

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.

1990-01-01

The objective of this study was to assess the relative value of invasive and noninvasive predictors of outcome in patients after unstable angina. Fifty-four patients with unstable angina who had 6-month follow-up after stabilization on medical therapy were evaluated. We prospectively compared 24-hour Holter ST-segment monitoring at admission, quantitative exercise thallium tomography, and cardiac catheterization 5 +/- 2 days after admission and analyzed their value for predicting a cardiac event in patients with unstable angina within 6 months. When patients with a favorable outcome (n = 40) were compared with patients with an unfavorable outcome (n = 11) no statistical difference was found in duration of ST shift of 1 mm or more on Holter monitoring (51 +/- 119 min compared with 37 +/- 43 min), exercise duration by the standard Bruce protocol (8.0 +/- 3.6 min compared with 7.9 +/- 3.1 min), exercise-induced ST depression (0.6 +/- 0.9 mm compared with 1.0 +/- 1.0 mm), and contrast left ventricular ejection fraction (70% +/- 10% compared with 69% +/- 15%). Patients with a favorable outcome were distinguished from those with an unfavorable outcome by a higher maximum rate-pressure product (24 x 10(3) +/- 6 x 10(3) compared with 18 x 10(3) +/- 7 x 10(3), P = 0.0025), smaller size of the reversible scintigraphic perfusion defect expressed as a percentage of total myocardium imaged (6% +/- 11% compared with 17% +/- 18%, P = 0.05) and a smaller number of vessels with stenosis of 50% or more (1.1 +/- 1.2 compared with 2.1 +/- 1.0, P = 0.01). On multiple logistic regression analysis, a history of previous myocardial infarction was the most powerful predictor of outcome. In patients without myocardial infarction, reversible exercise thallium perfusion defect size was the only predictor

Exercise testing in patients with variant angina: results, correlation with clinical and angiographic features and prognostic significance

Eighty-two patients with variant angina underwent a treadmill exercise test using 14 ECG leads, and 67 also underwent exercise thallium-201 scans. The test induced ST elevation in 25 patients (30%), ST depression in 21 (26%) and no ST-segment abnormality in 36 (44%). ST elevation during exercise occurred in the same ECG leads as during spontaneous attacks at rest, and was always associated with a large perfusion defect on the exercise thallium scan. In contrast, exercise-induced ST depression often did not occur in the leads that exhibited ST elevation during episodes at rest. The ST-segment response to exercise did not accurately predict coronary anatomy: Coronary stenoses greater than or equal to 70% were present in 14 of 25 patients (56%) with ST elevation, in 13 of 21 (62%) with ST depression and in 14 of 36 (39%) with no ST-segment abnormality (NS). However, the degree of disease activity did correlate with the result of the exercise test: ST elevation occurred during exercise in 11 of 14 patients who had an average of more than two spontaneous attacks per day, in 12 of 24 who had between two attacks per day and two per week, and in only two of 31 who had fewer than two attacks per week (p<0.005). ST elevation during exercise was reproducible in five of five patients retested during an active phase of their disease, but not in three of three patients who had been angina-free for a least 1 month before the repeat test. We conclude that in variant angina patients, the results of an exercise test correlate well with the degree of disease activity but not with coronary anatomy, and do not define a high-risk subgroup

Background: The complicated concept of quality of life (QOL) has been considered as an important criterion for health outcomes in chronic diseases, such as heart disease, in recent years. The aim of this study was to evaluate the QOL of patients with angina pectoris after treatment with enhanced external counterpulsation (EECP). Materials and Methods: This quasi-experimental study was conducted on 64 patients with angina pectoris undergoing EECP who came to Shahid Chamran and Sina Hospitals in Isfahan. Sampling was performed by the convenient method. Data were collected using a questionnaire containing socio-demographic and clinical data. A standard questionnaire called 36-item Short-Form Health Survey was also used. Questionnaires were completed through interviews and phone calls in three stages (before, immediately and three months after the treatment). The results were analyzed using descriptive statistics (frequency, mean, and standard deviation) and analytical statistics (paired t-test and repeated measures test) in SPSS11.5. Findings: The obtained results demonstrated that the majority of patients were men (59.4%) and aged 56-71 years. In addition, 57.8% had hypertension and 56.3% had hyperlipidemia. A history of myocardial infarction was found in 70.3% of the subjects and the familial history of coronary artery disease was detected in73.4%. Although QOL evaluations showed improvements in all subscales immediately and three months after the treatment, the changes were not statistically significant in case of general health, role limitations due to physical problems and role limitations due to mental problems Conclusions: Similar to previous research, this study showed QOL to improve in patients who undergo EECP. This improvement will remain stable three months after the treatment in all subscales. Therefore, EECP is an efficient noninvasive method in treating patients with angina pectoris and in developing their QOL. PMID:23493242

This paper describes the psychometric properties of the French version of the APQLQ (Angina Pectoris Quality of Life Questionnaire), that is to say, scaling assumptions, reliability and validity. This disease-specific Swedish questionnaire provides a global score as well as four subscores measuring physical activities, somatic symptoms, emotional distress, and life satisfaction. The French version was produced according to the forward-backward translation methodology. In a cross-sectional study, 183 coronary patients filled out the APQLQ and the MOS (Medical Outcomes Study) SF-36; 170 sent it back; the rate of missing data was low (1.3%). The factorial structure and the high level of inter-scale correlations (> 0.60) suggested that the APQLQ measured one global concept rather than separate domains. The multitrait analysis identified one problematic item correlated strongly with all domains. The internal consistency was good (alpha Cronbach > 0.70). The correlations with the SF-36 scales were consistent with what was expected. The distribution of the scores of the APQLQ according to the clinical severity of Angina Pectoris (AP) was as hypothesized: the more severe the AP, the more impaired the Quality of Life. The score significantly discriminated between symptomatic (n = 110) and asymptomatic patients (n = 60) except for the emotional distress scale (p = 0.14). We recommend to analyze the French APQLQ as an index rather than as a profile. Its reliability, concurrent and clinical validity allowed its use in clinical trials.

Clinical and angiographic characteristics of acute myocardial infarction caused by vasospastic angina without organic coronary heart disease

International Nuclear Information System (INIS)

Kim, Pum-Joon; Seung, Ki-Bae; Kim, Dong-Bin

2007-01-01

Vasospastic angina (VA) can occasionally cause acute myocardial infarction (AMI). From January 2003 to June 2005, coronary spastic angina was diagnosed in 292 patients by performing spasm provocation tests. Among the 292 patients, 21 (7.2% of all the VA patients) had an AMI. There were 20 patients who initially visited the emergency room for AMI without suffering prior VA. One patient with a history of VA had an AMI when he discontinued his medication. Among the 21 VA patients with AMI, 14 had experienced severe emotional stress before they visited the emergency room. The spasm provocation test showed that the VA patients with AMI had more multivessel and diffuse spasm than the VA patients without AMI (p<0.001). Clinically, the VA patients with AMI usually had their first symptom of VA as the severe chest pain of AMI. Two-thirds of the VA patients with AMI had experienced emotional stress before their AMI. Angiographically, the spasm provocation test for VA patients with AMI showed more multivessel and diffuse spasm than in VA patients without AMI. (author)

Lipoprotein-associated phospholipase A 2 (Lp-PLA 2 ), a biomarker of oxidation and inflammation, has been associated with increased coronary artery disease risk. To date, very few studies have examined the Chinese herbal drug Danshen or its extract on Lp-PLA 2 in patients with stable angina pectoris. In this study, we aim to investigate the effect of Danshen extract on Lp-PLA 2 level in patients with stable angina. This is a randomized, single-blind, placebo-controlled, adaptive clinical trial. A total of 156 patients meeting the eligibility criteria will be randomly assigned to either the Danshen extract (DanshenDuofensuanyan injection and Danshen drop spill) group or the placebo group in a 1:1 ratio. Participants will then undergo treatment with DanshenDuofensuanyan injection or placebo (glucose) during hospitalization, followed by open-label Danshen drop spill (30 pills/day) in Danshen extract group for 60 days after discharge. Because this is an adaptive trial, two interim analyses are prospectively planned. These will be performed after one-third and two-thirds of the patients, respectively, have completed the trial. On the basis of the results of these interim analyses, a data monitoring committee will determine how to modify aspects of the study without undermining the validity and integrity of the trial. The primary outcome measure is the serum level of Lp-PLA 2 in the Danshen extract group and the placebo group. The secondary outcomes include the proportion of patients who show a clinically significant change, which is defined as at least a 20-point improvement in angina frequency score on the Seattle Angina Questionnaire and the carotid intima-media thickness, which will be measured using ultrasound. Other secondary efficacy and safety outcomes will also be assessed. This study will provide evidence that Danshen extract is beneficial for stable angina and may establish a possible mechanism of Danshen treatment effects on cardiovascular disease. This

2002-01-01

Diagnostic usefulness of 99m Tc-hexakis-2-methoxy isobutyl isonitrile (MIBI) myocardial SPECT at rest was examined in 39 cases of coronary vasospastic angina pectoris who were diagnosed by a positive reaction to ergonovine provocation. SPECT was performed 45 minutes (early image) and 3 hours (delayed image) after the intravenous injection of approximately 600 MBq of MIBI. Decrease in accumulation was ranked by four defect scores (0: normal; 1: slight decrease; 2: moderate decrease; 3: severe decrease) and the total defect score was evaluated semiquantitatively. The washout rate between the normal area and the spasm area was also evaluated quantitatively using bull's eye. As a result, 15 cases (15/39; 38.4%) showed decreased accumulation in the early image and 27 cases (27/39; 69.2%) showed decreased accumulation in the delayed image. All of the cases which showed decreased accumulation in the early image had decreased accumulation in the delayed image as well. In 6 cases (6/34; 17.6%) showed ST wave changes during exercise ECG and 16 cases (16/34: 47%) showed decreased accumulation in the exercise myocardial SPECT. The washout rate of MIBI in the decreased accumulation area was significantly higher than that of the normal area. Of 32 ergonovine induced vasospastic area, 23 areas (72%) exhibited decreased accumulation in the delayed image for the same area. Decreased accumulation in the delayed image in MIBI was due to the enhanced washout, which, in turn, indicated declined retention of MIBI by mitochondrial membrane. In coronary vasospastic angina pectoris, spasm induced ischemia was thought to have an effect on the mitochondria. This study suggested that even with a normal exercise ECG and exercise myocardial SPECT, there's a strong possibility of coronary vasospastic angina pectoris if a decreased accumulation was found in the delayed image in the MIBI myocardial SPECT at rest. Hence, in diagnosing coronary vasospastic angina pectoris, the delayed image in the

Este estudio se centra en analizar las metodologías llevadas a cabo por docentes de Primaria para conocer el grado de implantación del modelo basado en competencias en este nivel educativo. La actualidad del tema y la falta de investigaciones en este nivel educativo motivan la realización de tal estudio. Concretamente, se trata de un estudio de caso de carácter descriptivo realizado en un centro de Educación Primaria en la Región de Murcia. Así, a través de entrevistas semiestructuradas, analizamos la práctica real de aula que emplean siete docentes –cinco mujeres y dos hombres de distintos niveles y especialidades–, para conocer cómo imparten sus clases. Las conclusiones apuntan a que los entrevistados aún no tienen asumido un modelo educativo basado en competencias, aunque se vislumbran indicios de una nueva reorientación de las metodologías empleadas y actividades desarrolladas con el objeto de la consecución de las ocho competencias básicas. Así, parece que los docentes se encuentran en un primer estadio de adaptación a la nueva concepción de los enfoques de enseñanza y aprendizaje.

Long-chain fatty acid (LCFA) is the main energy source for normal myocardium at rest, but in ischemic myocardium, the main energy substrate shifts from LCFA to glucose. 123I-BMIPP is a radiolabeled LCFA analog. In chronic stable angina without previous infarction, we suppose that reduced 123I-BMIPP uptake is related to the substrate shift in myocardium with decreased myocardial flow reserve (MFR). The purpose of this study was to relate 123I-BMIPP uptake to rest myocardial blood flow (MBF), hyperemic MBF, and MFR assessed with 15O-water positron emission tomography (PET). We enrolled 21 patients with chronic stable angina without previous infarction, all of whom underwent 123I-BMIPP single-photon emission computed tomography (SPECT) and 15O-water PET. The left ventricle was divided into 13 segments. In each segment, rest MBF and hyperemic MBF were measured by PET. 123I-BMIPP uptake was evaluated as follows: score 0=normal, 1=slightly decreased uptake, 2=moderately decreased uptake, 3=severely decreased uptake, and 4=complete defect. 123I-BMIPP uptake was compared with rest MBF, hyperemic MBF, and MFR. The numbers of segments with 123I-BMIPP scores 0, 1, 2, 3, and 4 were 178, 40, 25, 24, and 0, respectively. The rest MBFs for scores 0, 1, 2, and 3 were 0.93+/-0.25, 0.86+/-0.21, 0.97+/-0.30, and 0.99+/-0.37 ml/min/g, respectively. The hyperemic MBFs for scores 0, 1, 2, and 3 were 2.76+/-1.29, 1.84+/-0.74, 1.37+/-0.39, and 1.08+/-0.40 ml/min/g, respectively. The MFRs for scores 0, 1, 2, and 3 were 3.01+/-1.38, 2.20+/-0.95, 1.44+/-0.22, and 1.10+/-0.26, respectively. As 123I-BMIPP uptake declined, hyperemic MBF and MFR decreased. In chronic stable angina without previous infarction, reduced 123I-BMIPP uptake implies decreased MFR.

The anti-anginal efficacy of the selective I(f) inhibitor ivabradine has been demonstrated in controlled clinical trials. However, there is limited information about the safety and efficacy of a combined treatment of ivabradine with beta-blockers, particularly outside of clinical trials in every day practice. This analysis from the REDUCTION study evaluated the safety and efficacy of a combined therapy of beta-blockers and ivabradine in every day practice. In this multi-center study 4,954 patients with stable angina pectoris were treated with ivabradine in every day routine practice and underwent a clinical follow-up for 4 months. 344 of these patients received a co-medication with beta-blockers. Heart rate (HR), angina pectoris episodes, nitrate consumption, overall efficacy and tolerance were analyzed. After 4 months of treatment with ivabradine HR was reduced by 12.4 ± 11.6 bpm from 84.3 ± 14.6 to 72.0 ± 9.9 bpm, p every day practice.

During the last 40 years, Danshen injection has been widely used as an adjunctive therapy for angina pectoris in China, but its efficacy is not yet well defined. The objective of this study was to verify the efficacy of Danshen injection as adjunctive therapy in treating angina pectoris. The major databases including PubMed, Cochrane Library, Sino-Med, Medline, Embase, Google Scholar, China National Knowledge Infrastructure, Wanfang Databases, Chinese Scientific Journal Database, Chinese Biomedical Literature Database and the Chinese Science Citation Database were systematically searched for the published randomised controlled trials (RCTs) on Danshen injection until April 2016. Meta-analysis was conducted on the primary outcomes (i.e., the improvements in symptoms and electrocardiography (ECG)). The quality of the included RCTs was evaluated with the M scoring system (the refined Jadad scale). Based on the quality, year of publication and sample size of RCTs, sensitivity analysis and subgroup analysis were performed in this study. Ten RCTs, including 944 anginal patients, were identified in this meta-analysis. Compared with using antianginal agents (β-blockers, calcium antagonists, nitrates, etc.) alone, Danshen injection combined with antianginal agents had a better therapeutic effect in symptom improvement (odds ratio [OR], 3.66; 95% confidence interval [CI]: 2.50-5.36) and in ECG improvement (OR, 3.25; 95% CI: 1.74-6.08). This study showed that Danshen injection as adjunctive therapy seemed to be more effective than antianginal agents alone in treating angina pectoris. However, more evidence is needed to accurately evaluate the efficacy of Danshen injection because of the low methodological quality of the included RCTs.

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 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 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. Published by Elsevier Inc.

Kirschbaum, S.W.; Nieman, K.; Springeling, T.

2011-01-01

The background of this study was to evaluate additional adenosine magnetic resonance perfusion (MRP) imaging in the diagnostic workup of patients with suspected stable angina with computed tomography coronary angiography (CTCA) as first-line diagnostic modality. Two hundred and thirty symptomatic patients (male, 52%; age, 56 year) with suspected stable angina underwent CTCA. In patients with a stenosis of >50% as visually assessed, MRP was performed and the quantitative myocardial perfusion reserve index (MPRI) was calculated. Coronary flow reserve (CFR) using invasive coronary flow measurements served as the standard of reference. CTCA showed non-significant coronary artery disease (CAD) in 151/230 (66%) patients and significant CAD in 79/230 patients (34%), of whom 50 subsequently underwent MRP and CFR. MRP showed reduced perfusion in 32 patients (64%), which was confirmed by CFR in 27 (84%). All 18 cases of normal MRP (36%) were confirmed by CFR. The positive likelihood ratio of MRP for the presence of functional significant disease in patients with a lesion on CTCA was 4.49 (95% confidence interval [CI] 2.12-9.99). The negative likelihood ratio was 0.05 (95% CI 0.01-0.34). CTCA as first-line diagnostic modality excluded coronary artery disease in a high percentage of patients referred for diagnostic workup of suspected stable angina. MRP made a significant contribution to the detection of functional significant lesions in patients with a positive CTCA. (author)

This study sought to investigate the relationship between localization of high-intensity signals (HISs) on T1-weighted imaging (T1WI) with the noncontrast magnetic resonance technique and plaque morphology detected on optical coherence tomography, and the clinical severity of angina pectoris. Since the introduction of the T1WI noncontrast magnetic resonance technique for plaque imaging, some groups have reported that HISs in the coronary artery on T1WI are associated with a vulnerable morphology and future cardiac events. However, the association between the localization of HISs, such as coronary intrawall or intraluminal, and plaque morphology has not been investigated. One hundred lesions with either stable or unstable angina were included and divided into 3 groups according to the following criteria using T1WI. First, the plaques with the ratio between the signal intensities of coronary plaque and cardiac muscle ≤1.0 were classified as non-HISs (n = 39). Then, HISs with the ratio between the signal intensities of coronary plaque and cardiac muscle >1.0 were classified into 2 types by using cross-sectional T1WI. Those localized within the coronary wall when the lumen was identified were defined as intrawall HISs (n = 37), whereas those occupying the lumen when the lumen was not, or even if only partly, identified, were defined as intraluminal HISs (n = 24). Multivariate analysis revealed that intrawall HISs were associated with macrophage accumulation and the absence of calcification assessed by using optical coherence tomography. In contrast, thrombus and intimal vasculature were independent factors associated with intraluminal HISs. Furthermore, 50% of patients with intraluminal HISs experienced rest angina, such as Braunwald class II or III. This study shows that intrawall and intraluminal HISs on T1WI in patients with angina are related to the different types of vulnerable plaque morphology and the clinical severity.

This study investigated the changes in the blood rheology of patients with angina pectoris and ischemia reperfusion injury and their effect on thromboxane B 2 (TXB 2 ) levels to examine their relationship. Forty patients with unstable angina pectoris who underwent elective percutaneous coronary intervention (PCI) were selected for the unstable angina group (UA group) and forty patients deemed free of coronary heart disease by coronary angiography were selected for the control group. Venous blood samples were drawn from all participants; patients in the UA group had blood drawn 1 day before and 1 day after the PCI procedure. Blood samples were used to analyze blood rheology and examine hemodynamic parameters, at the same time radioimmunoassay was applied to measure the concentrations of serum endothelin-1 (ET-1) and TXB 2 , and an automatic biochemical analyzer was used to detect the content of superoxide dismutase (SOD) and malondialdehyde (MDA). Our results showed the patients in the UA group all presented hyperviscosity; however the levels were higher for the patients in the UA group (after surgery) than for those in the UA group (before surgery). Patients in the control group exhibited normal levels, and the differences among groups were significant in pairwise comparisons (Pangina pectoris and ischemia reperfusion injury. The higher than normal TXB 2 levels can be used as a marker of platelet activation and a reference for clinical risk stratification, thus having great significance for the prevention and treatment of ischemia reperfusion injury and assessment of disease progression.

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

Trimetazidine has been shown to improve angina pectoris and left ventricular (LV) function in diabetic patients with ischaemic cardiomyopathy. The objective of this study was to evaluate the effects of trimetazidine on recurrent angina pectoris and LV structure after drug-eluting stent (DES) implantation in elderly multivessel coronary heart disease (CHD) patients with diabetes mellitus (DM) and a left ventricular ejection fraction (LVEF) of ≥ 50 %. This was a single-centre, prospective, randomized, double-blind evaluation study. Between January 2010 and September 2010, 700 CHD patients with DM who were aged ≥ 65 years and undergoing coronary angiography at An Zhen Hospital (Beijing, China) were recruited and prospectively randomized to receive trimetazidine (20 mg three times daily) or placebo after DES implantation as an addition to conventional CHD treatment. The primary end points were the incidence of recurrent angina pectoris and measures of various echocardiographic parameters, which included LVEF. At 2-year follow-up, patients in the trimetazidine group (n = 255) showed significant improvements in the incidence (P = 0.024) and severity of angina pectoris, compared with the control group, as well as silent myocardial ischaemia (P = 0.009) and angina pectoris-free survival (P = 0.011). LV function and structure in trimetazidine-treated patients were relatively stable at 2-year follow-up, while they deteriorated in the control group (n = 255) with a significant difference between groups (all P angina pectoris as well as LV function and structure in elderly multivessel CHD patients with DM.

Full Text Available Introduction & Objective: Several studies have been performed to evaluate correlation of serum high sensitivity CRP (hs-CRP level with the prognosis of the patients with diagnosis of unstable angina, and by now different results were reported. The aim of this study was to assess correlation between serum hs-CRP level and inhospital prognosis and cardiac events in the patients with unstable angina. Materials & Methods: This descriptive analytic study was performed from Sep 2004 till Feb 2006 in Shahid Beheshti hospital. Kermanshah, Iran. Sera were collected from 250 patients for hs-CRP measurement. Exclusion criteria were: acute ST elevation MI, non ST elevation MI, patients with history of recent infection, patients with recent trauma and patients with serum high sensitive CRP level more than 10 mg/lit. Patients were divided into two groups, first group whose serum hs-CRP level was less than 3 mg/lit and second group whose serum hs-CRP level was between 3 and 10 mg/lit. They were followed for recurrent chest pain, arrhythmias, pulmonary edema, acute myocardial infarction and in hospital death. Results were analyzed using x² and t-test. Results: Mean age were 57±7.8 and 58±11.5 years in first group and second group respectively. There was statistically significant difference in some cardiac complications such as dyspnea, duration of hospitalization, recurrent chest pain, CCU admission (p<0.001 and in hospital myocardial infarction (p=0.03, between two groups. Some complications did not have significant difference such as pulmonary edema, cardiogenic shock, arrhythmia, S3, S4 and pulmonary rates .There was no mortality in both groups. Conclusion: According to the results, we can use serum hs-CRP level for risk stratification in the patients with diagnosis of unstable angina. Obviously the patients with high serum hs-CRP level need more attention whether early invasive management help these patients, may be the matter of later studies.

Long-chain fatty acid (LCFA) is the main energy source for normal myocardium at rest, but in ischemic myocardium, the main energy substrate shifts from LCFA to glucose. {sup 123}I-BMIPP is a radiolabeled LCFA analog. In chronic stable angina without previous infarction, we suppose that reduced {sup 123}I-BMIPP uptake is related to the substrate shift in myocardium with decreased myocardial flow reserve (MFR). The purpose of this study was to relate {sup 123}I-BMIPP uptake to rest myocardial blood flow (MBF), hyperemic MBF, and MFR assessed with {sup 15}O-water positron emission tomography (PET). We enrolled 21 patients with chronic stable angina without previous infarction, all of whom underwent {sup 123}I-BMIPP single-photon emission computed tomography (SPECT) and {sup 15}O-water PET. The left ventricle was divided into 13 segments. In each segment, rest MBF and hyperemic MBF were measured by PET. {sup 123}I-BMIPP uptake was evaluated as follows: score 0=normal, 1=slightly decreased uptake, 2=moderately decreased uptake, 3=severely decreased uptake, and 4=complete defect. {sup 123}I-BMIPP uptake was compared with rest MBF, hyperemic MBF, and MFR. The numbers of segments with {sup 123}I-BMIPP scores 0, 1, 2, 3, and 4 were 178, 40, 25, 24, and 0, respectively. The rest MBFs for scores 0, 1, 2, and 3 were 0.93{+-}0.25, 0.86{+-}0.21, 0.97{+-}0.30, and 0.99{+-}0.37 ml/min/g, respectively. The hyperemic MBFs for scores 0, 1, 2, and 3 were 2.76{+-}1.29, 1.84{+-}0.74, 1.37{+-}0.39, and 1.08{+-}0.40 ml/min/g, respectively. The MFRs for scores 0, 1, 2, and 3 were 3.01{+-}1.38, 2.20{+-}0.95, 1.44{+-}0.22, and 1.10{+-}0.26, respectively. As {sup 123}I-BMIPP uptake declined, hyperemic MBF and MFR decreased. In chronic stable angina without previous infarction, reduced {sup 123}I-BMIPP uptake implies decreased MFR. (orig.)

Con el fin de definir un tratamiento racional oportuno y orientar el diagnóstico molecular de las inmunodeficiencias primarias, se estableció un programa para el diagnóstico fenotípico de estas enfermedades en el departamento de Antioquia (Colombia, que comprende un análisis clínico y de laboratorio de los individuos que presentan infecciones recurrentes de evolución anormal. Entre el 1 de agosto de 1994 y el 31 de julio de 2002 se hizo el diagnóstico fenotípico de inmunodeficiencia primaria en 98 pacientes. Similar a lo informado en la literatura especializada, en esta región las deficiencias predominantes de anticuerpos fueron las más frecuentes (40,8% seguidas por las deficiencias combinadas (21,4%. Esta caracterización fenotípica ha permitido iniciar rápidamente el tratamiento adecuado y, en algunos casos, comenzar los estudios funcionales y moleculares que conduzcan al diagnóstico molecular definitivo.

Comparing systems for costing hospital treatments. The case of stable angina pectoris.

Science.gov (United States)

Larsen, Jytte; Skjoldborg, Ulla Slothuus

2004-03-01

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

Liang, C.S.; Coplin, B.; Wellington, K.

1985-01-01

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

To evaluate the cost-effectiveness of trimetazidine (TMZ) as add-on therapy to standard-of-care (SoC) compared to SoC alone in patients with chronic stable angina who did not respond adequately to first line therapy with b-blockers, nitrates or calcium channel antagonists in Greece. A Markov model with 3-month cycles and 1-year time horizon was developed to assess the comparators. The analysis was conducted from a third-party payer perspective. The clinical inputs and utility values were extracted from the published literature. Resource consumption data were obtained from local experts, using a questionnaire developed for the purpose of the study and were combined with unit cost data (in €2016) obtained from official sources. Cost effectiveness was assessed by calculating the incremental cost effectiveness ratio (ICER). Probabilistic sensitivity analysis (PSA) was performed to account for uncertainty and variation in the input parameters of the model. The analysis showed that the cost of TMZ plus SoC was €1755.57 versus €1751.76 of SoC alone. In terms of health outcomes, TMZ plus SoC was associated with 0.6650 QALYs versus 0.6562 QALYs for SoC alone. The incremental analysis resulted in an ICER of €430.67 per QALY gained. PSA revealed that the probability of TMZ plus SoC being cost-effective over SoC was 89 %, at a threshold of €34,000 per QALY gained. The results indicate that TMZ as add -on treatment may be a highly cost-effective option for the symptomatic treatment of patients with chronic stable angina in Greece relative to SoC alone.

El artículo brinda una visión panorámica del estado en que se encuentra el arte de la informatización de la atención primaria y la medicina general integral, en el mundo y en Cuba. Para ello, se sintetiza el origen prehistórico de ese nivel de atención y de la especialidad, así como el desarrollo contemporáneo de la informática y sus aplicaciones médicas; se define igualmente la atención primaria y su informática; se resumen los sistemas de información, las aplicaciones informáticas y sus desafíos; y se ofrece una visión práctica de la historia clínica-electrónica: corazón de la informática de atención primaria de salud y medicina general integral. Se concluye que Cuba ha trabajado 20 años informatizando la dispensarización y estadísticas para la gerencia de servicios de este nivel de atención, pero que también podría trabajar con el enfoque centrado en la vida del paciente, que contribuiría a crear una clasificación integradora de la salud con la enfermedad, y a computarizar la información y la toma de decisiones clínicas en el consultorio del médico, y en el futuro hasta en el hogar del paciente, elevando directamente la calidad de la atención primaria de salud.The informatization in primary health care is perceived as problem that is solved by creating computer networks between the family physicians' offices and the polyclinics.

Clinical usefulness of once-daily administration of 20 to 60 mg of efonidipine hydrochloride and coronary hemodynamics during exercise 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 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 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)

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.

Full Text Available Las inmunodeficiencias primarias son un grupo heterogéneo de desórdenes hereditarios que afectan los mecanismos de la inmunidad inespecífica y específica del huésped. En la mayoría de los casos se manifiestan en los primeros cinco años de vida, pero pueden presentarse a cualquier edad, encontrándose un gran predominio masculino (Oleastro, 2001. Han sido clasificadas, de acuerdo al defecto molecular que presentan, en inmunodeficiencias ligadas al cromosoma X e inmunodeficiencias autosómicas recesivas (Jones, 2000. Su prevalencia se ha establecido en 1 por cada 10.000 nacidos vivos, aumentando considerablemente desde el primer caso reportado en 1969 (Lim, 2004. Este incremento puede estar favorecido por la existencia de pruebas especializadas de laboratorio que permiten hacer una detección temprana de anormalidades inmunológicas. La valoración de la inmunocompetencia en un individuo con sospecha de inmunodeficiencia primaria requiere de un análisis cuantitativo, cualitativo o estructural y de estudios funcionales que permiten detectar la integridad de sus mecanismos de defensa. De acuerdo con el componente inmune que se quiere evaluar existen diferentes estudios que se pueden realizar de acuerdo a su grado de complejidad en pruebas de primera, segunda y tercera etapa, las cuales serán revisadas en este artículo.

Full Text Available Objective: To discuss the effect of Yixinkangtai Capsule combined with diltiazem on endothelial function, blood viscosity and lipid metabolism in patients with unstable angina pectoris. Methods: A total of 150 patients with unstable angina pectoris who were treated in the hospital between February 2014 and February 2017 were divided into the control group (n=75 and the research group (n=75 according to the random number table method. Control group received clinical conventional therapy, research group received Yixinkangtai Capsule combined with diltiazem therapy on the basis of conventional therapy, and both groups received 3 months of treatment. Differences in endothelial function, blood viscosity and lipid metabolism were compared between the two groups of patients before and after treatment. Results: Before treatment, the differences in serum levels of endothelial function indexes, blood viscosity indexes and lipid metabolism indexes were not statistically significant between the two groups. After 3 months of treatment, serum NO level of research group was higher than that of control group while ET-1 level was lower than that of control group; serum blood viscosity index TXB2 content of research group was lower than that of control group while PGI2 content was higher than that of control group; serum lipid metabolism indexes TG, TC and LDL-C contents of research group were lower than those of control group while HDL-C content was higher than that of control group. Conclusion: Yixinkangtai Capsule combined with diltiazem therapy can effectively optimize the endothelial function, reduce the blood viscosity and balance the lipid metabolism in patients with unstable angina pectoris.

Full Text Available El objetivo de la investigación fue caracterizar los elementos de estudio de la educación para la alimentación saludable en la escuela primaria. Esto fue para establecer líneas de investigaciones del contexto escolar y desarrollar mejores prácticas educativas integradoras que involucren a educandos, docentes y la comunidad. El estudio de caso fue realizado mediante una observación participante a través de un taller con ejes en educación para la alimentación y la sustentabilidad realizado a lo largo de un semestre en una escuela rural multigrado. Se identificaron elementos que deben considerarse en la educación para la alimentación saludable en la escuela primaria: la vinculación entre la preparación de los desayunos escolares y los procesos educativos, las orientaciones transversales con educación ambiental y sustentabilidad, así como la urgente reconfiguración de los contenidos conceptuales, procedimentales y valorales.

En muchas áreas del mundo, la tuberculosis tiene gran prevalencia y sigue siendo la principal causa de insuficiencia suprarrenal. Clínicamente, esta enfermedad permanece sin sintomatología durante sus primeros estadios, debido a que la pérdida de la función adrenal suele ser progresiva; los síntomas tienen aparición gradual e insidiosa, en su mayoría inespecíficos. Presentamos el caso de dos mujeres con cuadro clínico de insuficiencia adrenal primaria crónica, con afección bilateral de ambas ...

Full Text Available Estudiamos la dispersión primaria diurna de las semillas de Dacryodes chimantensisy Protium paniculatum (Burseraceae en un bosque de tierra firme de la Amazoniacolombiana. Desde diciembre de 1999 hasta junio de 2000 registramos las visitas defrugívoros, la remoción de frutos y la dispersión primaria de semillas de cincoindividuos por especie. Encontramos que D. chimantensis presenta en promediouna mayor altura, DAP, área de proyección de la copa y mayores cosechas que P.paniculatum. El porcentaje del valor promedio de frutos maduros de D. chimantensisosciló entre el 3 y el 21% del tamaño de la cosecha durante toda la estación de frutos,mientras que este porcentaje en P. paniculatum varió entre el 1 y 15%. Observamosactividad frugívora diurna en cuatro de los cinco individuos de D. chimantensisestudiados, mientras que en los individuos de P. paniculatum no se presentófrugivoría diurna. Únicamente Amazona festiva y A. amazonica consumieron frutosde D. chimantensis y removieron en promedio 1.8 % de los frutos por árbol, pero noalejaron semillas viables del parental (dispersión primaria. En las trampas ubicadasbajo el área de la proyección de la copa sobre el suelo, encontramos que el númerode frutos probados, intactos y dañados por frugívoros fue similar para las dosespecies. Las cosechas pequeñas, el número reducido de frutos maduros y las bajastasas de reducción de la cosecha, sumado a las pocas visitas diurnas, la baja remocióny dispersión primaria diurna de semillas por parte de los frugívoros, sugieren queestas dos especies tuvieron una dispersión limitada.

Numerous controlled studies have shown that nitrates, beta blockers, and calcium antagonists are effective in the treatment of stable angina pectoris. The pharmacokinetics, pharmacodynamics, and hemodynamic effects of these agents are different, and thus combination therapy offers additive improvement and also counterbalancing of the undesirable side effects of each drug. The choice of therapy depends on the severity of symptoms, associated diseases, compliance, side effects, and status of left ventricular function. The main mechanism of improvement is a decrease in myocardial oxygen consumption, though an increase in coronary blood flow is another potential reason for the use of calcium blockers. This review considers the properties of these drugs, their mechanism of action, and the results of randomized studies.
