Project description:Patients on oral anticoagulation (OAC), who are referred for coronary artery stenting account for about 5% of the whole population undergoing percutaneous coronary intervention (PCI). Although relatively small, this patient subset poses particular problems owing to the need to balance carefully the risk of bleeding against the risk of stent thrombosis and thromboembolism. Triple therapy (TT) of OAC, aspirin and clopidogrel appears as the most effective for prevention of stent thrombosis and thromboembolism. However, an increased incidence of major bleeding is to be expected during follow-up. Therefore, TT should be prolonged for as short a time as possible, and implantation of drug-eluting stents avoided. Frequent monitoring of international normalized ratio is also warranted, and the intensity of OAC should be targeted at the lower limit of the therapeutic range. Gastric protection should also be considered for all patients on medium- to long-term TT, owing to the observed highest incidence of bleeding at the gastrointestinal site. Peri-procedural management is cumbersome, and a substantial incidence of in-hospital major bleeding has been reported. Since this latter is more related to procedural variables than to TT itself, choice of radial access, avoidance of glycoprotein IIb/IIIa inhibitors, and preference for not interrupting effective OAC should be implemented. However, the evidence on which the recommendations for managing this patient subset are based is limited and of relative poor quality. While waiting for the results of ongoing, large prospective studies that are aimed at conclusively determining optimal medium- to long-term antithrombotic treatment, the official recommendations issued by the Working Group on Thrombosis of the European Society of Cardiology on the management of patients on OAC undergoing PCI with stenting should followed.

Project description:ObjectivesRandomized acute coronary syndrome (ACS) trials testing various antithrombotic (AT) regimens have largely excluded patients with coexisting conditions and indications for anticoagulation (AC). The purpose of this study is to examine the 2-year clinical outcomes of patients with ACS with indication for AC due to venous thromboembolism (VTE) during hospitalization for the ACS event or a prior or new diagnosis of atrial fibrillation (AF) with a CHADS2 (Congestive heart failure; Hypertension; Age; Diabetes; previous ischemic Stroke) score ?2.MethodsACS patients with AC indication from 2004 to 2009 were identified (n = 619). A Cox proportional hazards model was used to examine the primary efficacy outcome of major adverse cardiovascular events (MACE) including all-cause death, myocardial infarction (MI) or stroke. The primary explanatory variable was at-discharge antithrombotic strategy [single antiplatelet ± AC, dual antiplatelet (DAP) ± AC or AC only; referent DAP + AC].ResultsA total of 261 (42.2%) patients had a MACE event. AT strategy was not a significant factor for MACE (all p > 0.09). The factors associated with MACE were high mortality risk score [hazard ratio (HR)=1.87, 95% confidence interval (CI): 1.39- 2.52; p < 0.001), prior MI (HR = 1.44, 95% CI: 1.03-2.01; p= 0.033) and presentation of ST elevation MI (HR = 2.70, 95% CI: 1.61-4.51; p < 0.001) or non-ST elevation MI (HR = 1.70, 95% CI: 1.15-2.49; p < 0.001) compared with angina.ConclusionsIn this real world observational study, the at-discharge AT strategy was not significantly associated with the 2-year risk of MACE. These findings do not negate the need for randomized trials to generate evidence-based approaches to management of this important population.

Project description:Eisenmenger's syndrome is a complex multisystem disease which occurs as a consequence of large left to right shunt affecting the pulmonary vasculature causing suprasystemic pulmonary artery pressures and subsequent right to left shunt. Usually Eisenmenger's syndrome is characterised by coronary artery dilation but coronary artery disease and occurrence of acute coronary syndrome is a rare association seldom described in literature. We present the case of a 33-year-old man who presented with an anterior wall ST elevation mycocardial infarction and was thrombolysed. The occurrence of acute coronary event in a case of Eisenmenger's syndrome is a rare event and needs to be discussed and kept in mind by physicians and cardiologists who deal with such cases so that a high index of suspicion may be developed and emergent management may be possible.

Project description:Coronary artery disease is one of the leading causes of morbidity and mortality, and its prevalence increases with age. The growing number of older patients and their differential characteristics make its management a challenge in clinical practice. The aim of this review is to summarize the state-of-the-art in diagnosis and treatment of acute coronary syndromes in this subgroup of patients. This comprises peculiarities of ST-segment elevation myocardial infarction (STEMI) management, updated evidence of non-STEMI therapeutic strategies, individualization of antiplatelet treatment (weighting ischemic and hemorrhagic risks), as well as assessment of geriatric conditions and ethical issues in decision making.

Project description:Vasospastic angina results from temporary spasm of one or more coronary segments. Although prognosis of patients presenting with coronary vasospasm appears to be generally good, multivessel coronary vasospasm may increase the risk of life-threatening cardiac events. We present a case of a 51-year-old man admitted to the emergency room due to severe retrosternal pain, who was documented with multifocal coronary vasospasm. <Learning objective: The case described illustrates the importance of recognizing coronary vasospasm as a cause of reversible ischemia. Although vasospastic angina is associated with a favorable prognosis, multivessel involvement may increase the risk of life-threatening cardiac events.>.

Project description:BackgroundThe introduction of point-of-care devices for the management of patients on oral anticoagulation allows self-testing by the patient at home. Patients who self-test can either adjust their medication according to a pre-determined dose-INR (international normalized ratio) schedule (self-management), or they can call a clinic to be told the appropriate dose adjustment (self-monitoring). Increasing evidence suggests self-testing of oral anticoagulant therapy is equal to or better than standard monitoring. This is an updated version of the original review published in 2010.ObjectivesTo evaluate the effects on thrombotic events, major haemorrhages, and all-cause mortality of self-monitoring or self-management of oral anticoagulant therapy compared to standard monitoring.Search methodsFor this review update, we re-ran the searches of the Cochrane Central Register of Controlled Trials (CENTRAL), 2015, Issue 6, the Cochrane Library, MEDLINE (Ovid, 1946 to June week 4 2015), Embase (Ovid, 1980 to 2015 week 27) on 1 July 2015. We checked bibliographies and contacted manufacturers and authors of relevant studies. We did not apply any language restrictions .Selection criteriaOutcomes analysed were thromboembolic events, mortality, major haemorrhage, minor haemorrhage, tests in therapeutic range, frequency of testing, and feasibility of self-monitoring and self-management.Data collection and analysisReview authors independently extracted data and we used a fixed-effect model with the Mantzel-Haenzel method to calculate the pooled risk ratio (RR) and Peto's method to verify the results for uncommon outcomes. We examined heterogeneity amongst studies with the Chi(2) and I(2) statistics and used GRADE methodology to assess the quality of evidence.Main resultsWe identified 28 randomised trials including 8950 participants (newly incorporated in this update: 10 trials including 4227 participants). The overall quality of the evidence was generally low to moderate. Pooled estimates showed a reduction in thromboembolic events (RR 0.58, 95% CI 0.45 to 0.75; participants = 7594; studies = 18; moderate quality of evidence). Both, trials of self-management or self-monitoring showed reductions in thromboembolic events (RR 0.47, 95% CI 0.31 to 0.70; participants = 3497; studies = 11) and (RR 0.69, 95% CI 0.49 to 0.97; participants = 4097; studies = 7), respectively; the quality of evidence for both interventions was moderate. No reduction in all-cause mortality was found (RR 0.85, 95% CI 0.71 to 1.01; participants = 6358; studies = 11; moderate quality of evidence). While self-management caused a reduction in all-cause mortality (RR 0.55, 95% CI 0.36 to 0.84; participants = 3058; studies = 8); self-monitoring did not (RR 0.94, 95% CI 0.78 to 1.15; participants = 3300; studies = 3); the quality of evidence for both interventions was moderate. In 20 trials (8018 participants) self-monitoring or self-management did not reduce major haemorrhage (RR 0.95, 95% CI, 0.80 to 1.12; moderate quality of evidence). There was no significant difference found for minor haemorrhage (RR 0.97, 95% CI 0.67 to 1.41; participants = 5365; studies = 13). The quality of evidence was graded as low because of serious risk of bias and substantial heterogeneity (I(2) = 82%).Authors' conclusionsParticipants who self-monitor or self-manage can improve the quality of their oral anticoagulation therapy. Thromboembolic events were reduced, for both those self-monitoring or self-managing oral anticoagulation therapy. A reduction in all-cause mortality was observed in trials of self-management but not in self-monitoring, with no effects on major haemorrhage.

Project description:Patients surviving an acute coronary syndrome (ACS) remain at increased risk of ischemic events long term. This paper reviews current evidence and guidelines for oral antiplatelet therapy for secondary prevention following ACS, with respect to decreased risk of ischemic events versus bleeding risk according to individual patient characteristics and risk factors. Specifically, data are reviewed from clinical studies of clopidogrel, prasugrel, ticagrelor and vorapaxar, as well as the results of systematic reviews and meta-analyses looking at the benefits and risks of oral antiplatelet therapy, and the relative merits of shorter versus longer duration of dual antiplatelet therapy, in different patient groups.

Project description:A 40-year-old female with a history of steroid therapy for juvenile rheumatoid arthritis was brought to our hospital because of chest pain. A diagnosis of non-ST elevation myocardial infarction was made, and emergency coronary angiography revealed stenotic lesions with severe calcification in the left anterior descending artery and the right coronary artery. Percutaneous coronary intervention with rotational atherectomy followed by a drug-coated balloon was performed to the lesion in the left anterior descending artery. The patient had characteristic physical findings including short stature, a round face, and 'knuckle-dimple sign'. Whole-body computed tomography showed many ectopic calcifications, indicating Albright's hereditary osteodystrophy. Ellsworth-Howard test revealed that urinary cyclic adenosine monophosphate response was positive, thus a diagnosis of pseudo-pseudohypoparathyroidism (PPHP) was made. Here, we describe a rare case of PPHP complicated by acute coronary syndrome with severely calcified coronary arteries.Learning objectivePseudo-pseudohypoparathyroidism (PPHP) presents with several characteristic physical findings and ectopic calcifications. Since PPHP involves coronary artery calcification as in the present case, it may be considered as a cause of coronary artery disease.
