Review of Acute Coronary Syndrome Diagnosis and ManagementKalra, Sumit, Duggal, Sonia, Valdez, Gerson, Smalligan, Roger D. 01 April 2008 (has links)
Acute coronary syndrome (ACS) refers to a group of clinical conditions caused by myocardial ischemia including unstable angina, non-ST-segment elevation myocardial infarction (NSTEMI), and ST-segmcnt elevation myocardial infarction (STEMI). Appropriate and accurate diagnosis has life-saving implications and requires a quick but thorough evaluation of the patient's history, physical examination, electrocardiogram, radiographic studies, and cardiac biomarkers. The management of patients with suspected or confirmed ACS continues to evolve as new evidence from clinical trials is considered and as new technology becomes available to both primary care physicians and cardiologists. Low- and intermediate-risk patients have frequently been managed in a chest pain center or in the emergency department. While stress testing with or without radionuclide imaging is the most common evaluation method, a CT angiogram is sometimes substituted High-risk patients are often managed with an early invasive strategy involving left heart catheterization with a goal of prompt revascularization of at-risk, viable myocardium. With the increased availability of cardiac catheterization facilities, patients with STEMI are more commonly being managed with primary percutaneous coronary intervention, although thrombolysis is still used where such facilities are not immediately available. This article provides primary care physicians with a concise review of the pathophysiology, clinical evaluation, and management of ACS based on the best available evidence in 2008.

The role of the socio-economic environment on medical outcomes after ST-segment elevation myocardial infarctionRoth, Christian, Berger, Rudolf, Kuhn, Michael January 2019 (has links) (PDF)
Background:
According to the World Health Organization, coronary artery disease (CAD), including ST-segment
elevation myocardial infarction (STEMI), is the most common cause of death worldwide as well as in Europe and
Austria. There is valid data on the impact of conventional risk factors on the medical outcomes for STEMI patients.
However, only few studies examine the role of the socio-economic environment for medical outcomes. The main
task of this study is to investigate if the socio-economic environment of patients who underwent percutaneous
coronary intervention (PCI) after STEMI has an impact on the distribution of risk factors and medical outcomes.
Methods:
The study focuses on the population of the City of Vienna, Austria, and includes 870 STEMI patients, who
underwent PCI at the General Hospital of Vienna (AKH Wien) between 2008 and 2012. The following data were
collected: conventional risk factors (hypertension, hyperlipidemia, diabetes, overweight, smoking, family history and
vascular disease) and socio-economic indicators of the patient's
residential district (number of residents, income
pre-tax, residents per general practitioner, residents per internal specialist, compulsory education only, academic
degree and rate of unemployment). Cox regressions were performed to evaluate the impact of socio-economic
environment and conventional risk factors on survival.
Results:
Most of the conventional risk factors show a significant difference between deceased and surviving patients.
The study revealed significant differences across districts in relation to the socio-economic background of STEMI
patients. Surprisingly, medical outcomes, as measured by the survival of patients, are significantly related to a patient's
district of residence (
p
-Value = 0.028) but not in a systematic way as far as the socio-economic environment of These
districts is concerned.
Conclusions:
The study provides intuitive evidence for a hitherto understudied Central European context on the link
between socio-economic environment and conventional risk factors at population level and the link between
conventional risk factors and survival both at the population at the individual level. While this is in line with previous
evidence and suggestive of the incorporation of measures of socio-economic status (SES) into policy & guidelines
toward the management of CAD, more data on the SES -
STEMI nexus are needed at individual level.

Dosagem sérica da enzima creatinafosfoquinase-isoenzima MB (CK-MB) e de troponina I (cTnI) de cães eletrocardiograficamente normais e naqueles com desníveis (infra e supra) do segmento ST, utilizando ensaio imunométrico por quimioluminescência / Serum determination of creatinephosphokinase-isoenzyme MB (CK-MB) enzyme and of troponin I (cTnI) in electrocardiographic normal dogs and in those with ST deviation (elevation or depression) by a chemiluminescent immunometric assaySantos, Andre Luis Fernandes dos 11 March 2005 (has links)
Ao contrário do homem, as cardiopatias de natureza hipóxica/isquêmica são pouco relatadas nos cães. Raros são os relatos de infarto agudo do miocárdio (IAM) nesses espécimes; entretanto, existem achados eletrocardiográficos que indicam hipóxia/isquemia miocárdica, como os desníveis (infra e supra) do segmento ST. Com o intuito de constatar algum dano nas células do miocárdio em condições de má perfusão, utilizaram-se 38 cães, dos quais 20 com traçados eletrocardiográficos normais e 18 com desníveis (infra e supra) do segmento ST, na derivação DII, velocidade de 50 mm/s e sensibilidade N. Nos animais normais (grupo 1), a dosagem sérica da enzima creatinafosfoquinase isoenzima MB (CK-MB) e da troponina I (cTnI) destinou-se à obtenção dos valores de referência (em ng/mL). Estes valores de referência foram confrontados com os obtidos de cães portadores de desnível (grupo 2), permitindo confirmar ou não a injúria miocárdica. Em relação à CK-MB, os cães do grupo 1 apresentaram média de 0,54 ng/mL e desvio-padrão de 0,89 ng/mL e os do grupo 2 apresentaram média de 0,44 ng/mL e desvio-padrão de 1,106 ng/mL. A média e o desvio-padrão foram, respectivamente, de 0,16 ng/mL e 0,110 ng/mL e de 0,20 ng/mL e 0,111 ng/mL, nos grupos 1 e 2. Houve 18 valores nulos de CK-MB, igualmente distribuídos entre ambos os grupos. O grupo 1 apresentou três valores nulos para cTnI. Houve diferença marcante em relação à idade, sendo o grupo 1 constituído por animais, preponderantemente, abaixo de 7 anos; o contrário ocorreu no grupo 2. São significativas, ao nível de significância de 5%, as associações da variável CK-MB com as variáveis idade, massa e CK-T (creatinafosfoquinase total) no grupo 1, e com a variável CK-T no grupo 2. A variável cTnI não apresentou evidências de associação, ao nível de significância de 5% , com as variáveis idade, massa, CK-T e nível sérico de potássio, para cada um dos níveis da variável grupo. Tanto para a variável CK-MB quanto para a cTnI, não houve diferenças significativas, ao nível de 5%, entre os grupos 1 e 2. Conclui-se que é possível a utilização do \"kit\" de ensaio imunométrico quimioluminescente humano para a espécie canina e que a hipóxia/isquemia, revelada pelo desnível do segmento ST, não acarreta dano miocárdico, ou que este é mínimo. / Although very often in men, hypoxic and ischemic heart diseases are poorly documented in dogs. There are few reports of acute myocardial infarction (AMI) in this species. However, some electrocardiographic findings may suggest myocardium hypoxia/ischemia, like ST segment elevation or depression. In order to investigate myocardial cells injury in poor perfusion conditions, 38 dogs, being 20 with normal electrocardiogram and 18 with ST segment elevation or depression in lead II, at a paper speed of 50 mm/sec and N sensibility (1 mV = 1cm), were included. Serum measurement of creatinephosphokinase isoenzyme MB (CK-MB) enzym and troponin I (cTnI) in normal dogs (group 1) determined reference values (in ng/ml). These values were compared to those obtained in dogs with deviation (group 2), which allowed confirmation or not of myocardial injury. CK-MB mean values obtained from dogs in groups 1 and 2 was 0,54 ng/mL (SD±0,54 ng/mL) and 0,44 ng/mL (SD±1,106), respectively. Mean cTnI values in groups 1 and 2 was 0,16 ng/mL (SD±0,110 ng/mL) and 0,20 ng/mL (SD±0,111 ng/mL) respectively. Three cTnI null values were found in group 1. There was a marked difference concerning to age, being group 1 composed, mainly, by animals ageing under 7 years, on the contrary of group 2. At a significance level of 5%, was significant the relation of CK-MB with age, mass and total creatinephosphokinase (CK-T) in group 1 and with CK-T in group 2. There is no relation, at a significance level of 5%, of cTnI with age, mass, CK-T or serum potassium concentration, for each level of group variable. Both CK-MB and cTnI variables showed no difference, at 5% level, between groups 1 and 2. In conclusion, it is possible to use the human chemiluminescent immunometric assay kit in canine species and that hypoxia/ischemia revealed by ST segment deviation does not mean significant myocardium injury.

Tako-Tsubo Syndrome as a Consequence of Transient Ischemic AttackAbi-Saleh, Bernard, Iskandar, Said B., Schoondyke, Jeffrey W., Fahrig, Stephen 01 December 2006 (has links) (PDF)
An 82-year-old woman presented to the emergency department with chest pain after sustaining a transient ischemic attack 1 week prior to presentation. Electrocardiography revealed ST-segment elevation in leads I, II, aVF, and V3 through V6. Coronary angiography demonstrated nearly normal coronaries but left ventriculography showed apical akinesis and basal hyperkinesis. One month later her follow-up echocardiography showed no wall motion abnormalities. Several reports of tako-tsubo syndrome or transient left ventricular apical ballooning have been described, especially in Japan. We present a case with the typical features of the syndrome after a cerebrovascular accident.

Caractérisation de la plaque athérothrombotique à la phase aigüe de l'infarctus du myocarde en imagerie endocoronaire et marqueurs biologiques thrombotiques / Intracoronary imaging characterization of atherothrombotic plaque in acute myocardial infarction and biological markers of thrombosisRoule, Vincent 03 December 2019 (has links)
L’activité plaquettaire joue un rôle clé dans la physiopathologie de l’infarctus du myocarde avec sus-décalage du segment ST (IDM ST+). La réactivité plaquettaire est augmentée lors d’un IDM ST+, traité par angioplastie primaire ou par fibrinolyse avec succès. La relation entre la réactivité plaquettaire résiduelle après un pré-traitement, la charge athérothrombotique et la qualité de la reperfusion myocardique reste peu décrite dans le cadre des IDM ST+. La tomographie par cohérence optique et celle plus récente par domaine de fréquence offrent une imagerie de haute résolution permettant l’identification et la quantification précise de la charge athérothrombotique intracoronaire (CAT). La CAT résiduelle intra-stent peut aider à mieux comprendre la relation entre la réactivité plaquettaire et la reperfusion. Dans un premier temps, nous avons évalué la précision des tests VerifyNow et PFA en comparaison à l’agrégométrie optique pour la détection de l’hyperréactivité plaquettaire dans le contexte particulier des IDM ST+ traités par fibrinolyse avec succès. Nous avons aussi décrit les caractéristiques de la CAT avant et après angioplastie selon la présence d’une rupture de plaque ou d’une érosion coronaire chez des patients traités par fibrinolyse avec succès. Ensuite, nous avons étudié la relation entre la réactivité plaquettaire résiduelle (en réponse au ticagrelor et à l’aspirine) mesurée par VerifyNow et la reperfusion myocardique chez des patients traités par angioplastie primaire. En parallèle, nous avons décrit la relation entre la reperfusion myocardique et la CAT résiduelle intra-stent dans la même cohorte. / Platelet activity plays a key role in the pathophysiology of ST-segment elevation myocardial infarction (STEMI). Platelet reactivity is enhanced after STEMI treated with primary percutaneous coronary intervention (PCI) or successful thrombolysis. The relationship between residual platelet reactivity after pre-treatment, the atherothrombotic burden and the quality of reperfusion remains poorly described in STEMI. Optical coherence tomography (OCT) and optical frequency domain imaging (OFDI) provide high resolution imaging allowing identification and accurate quantification of intracoronary atherothrombotic burden (ATB). Residual in-stent ATB may help to better understand the relation between platelet reactivity and reperfusion. First, we assessed the accuracy of the point-of-care tests VerifyNow and PFA in comparison to light transmittance aggregometry to detect high on-treatment platelet reactivity (HPR) in the particular setting of STEMI successfully treated with fibrinolysis. We also described the characteristics of ATB before and after PCI according to the underlying presence of rupture or erosion in patients successfully treated with fibrinolysis. Then, we assessed the relationship between residual platelet reactivity (in response to ticagrelor and aspirin) using VerifyNow and myocardial reperfusion in primary PCI patients. In parallel, we studied the relationship between myocardial reperfusion and residual in-stent ATB in the same cohort.

A Case of Anomalous Left Anterior Descending Artery Originating From the Right Sinus of ValsalvaPatel, Niravkumar, Bhogal, Sukhdeep, Ramu, Vijay, Helton, Thomas 01 June 2021 (has links)
The anomalous origin of coronary arteries has been extensively documented in the literature. Most of the anomalies are incidentally found either during coronary angiography or imaging studies and are usually benign; however, malignant outcomes have been reported in the literature. Here, we present the case of a 76-year-old male with non-ST segment elevation myocardial infarction who was found to have an asymptomatic anomalous origin left anterior descending artery from the right sinus of Valsalva.

Modélisation des stratégies de reperfusion de l’infarctus du myocarde / Modeling of myocardial reperfusion strategiesKhoury, Carlos H. El 01 March 2016 (has links)
Objectifs. L'infarctus aigu du myocarde (IDM) touche chaque année plus de 120 000 personnes en France. Nous nous sommes intéressés à la prise en charge du SCA avec sus-décalage du segment ST (ST+). Deux stratégies de revascularisation coronaires s'offrent à nous : la thrombolyse intraveineuse et l'angioplastie primaire. Notre travail a évalué l'impact du choix de ces stratégies dans la phase aiguë de l'infarctus du myocarde, à travers la mise en place d'un réseau associant la médecine d'urgence et la cardiologie interventionnelle autour d'un référentiel partagé. Méthode. Nous avons mis en place un réseau cardiologie - urgence (RESCUe), qui a fédéré au sein d'une association 37 structures d'urgence (SU), 19 structures mobiles d'urgence et de réanimation (SMUR) et 10 centres de cardiologie interventionnelle (CCI) dans un bassin géographique de 3 millions d'habitants. Notre méthode de travail s'articulait autour de trois axes : édition de référentiels partagés, formation et évaluation. Résultats. Dès la mise en place de RESCUe, nous avons lancé un essai multicentrique, contrôlé et randomisé, l'étude AGIR². En douze mois 320 SCA ST+ ont été inclus. Dès la prise en charge en SMUR tous les patients ont reçu 250 mg d'aspirine, 600 mg de clopidogrel, un bolus intraveineux de 60 IU/kg d'héparine avant d'être transférés en CCI pour une angioplastie primaire. Si le bénéfice d'une administration de tirofiban en SMUR n'était pas supérieur à son administration en CCI, AGIR² a conforté les bases d'une collaboration en réseau entre médecine d'urgence et cardiologie interventionnelle autour d'un référentiel thérapeutique partagé. Depuis, l'angioplastie primaire est progressivement devenue la stratégie de reperfusion de référence du SCA ST+ sur notre bassin. Pour évaluer son impact nous avons mis en place un registre observationnel couvrant l'ensemble des SU, SMUR et CCI du réseau. Entre 2009 et 2013 nous avons pris en charge 2418 patients en SMUR avec un diagnostic d'infarctus aigu du myocarde. Parmi eux, 2119 (87.6%) ont bénéficié d'une angioplastie primaire et 299 (12.4%) d'une thrombolyse intraveineuse. Nous avons observé une augmentation du recours à l'angioplastie primaire de 78.4% en 2009 à 95.9% en 2013 (P<0.001). Le délai médian ECG - arrivée en CCI était de 48 min, ECG - angioplastie 94 min et arrivée – angioplastie 43 min. Les délais symptôme – ECG et ECG – thrombolyse sont restés stables de 2009 à 2013, mais les délais symptôme – angioplastie et ECG – arrivée en CCI – angioplastie ont diminué (P<0.001). Au total 2146 (89.2%) patients avaient un délai ECG – arrivée en CCI ≤90 min, un délai confortant le choix d'une angioplastie primaire chez 97.7% d'entre eux en 2013, conformément aux recommandations. De 2009 à 2013, la mortalité hospitalière (4-6%) et celle à 30 jours (6-8%) est restée stable. Nous avons complété notre travail par une analyse de la conformité des mesures de prévention secondaire aux recommandations. A un an post-IDM, l'association bétabloquants – aspirine – statines – inhibiteurs de l'enzyme de conversion et la correction des facteurs de risque était liée à une meilleure survie. Parmi les 5161 patients pris en charge dans nos SU et en SMUR et sortis vivant de CCI, 2991 (58%) ont bénéficié de cette stratégie optimale avec un HR de 0.12 (95% CI 0.07–0.22; P<0.001). Les patients les plus graves étaient ceux les moins bien traités, à cause des contre-indications aux traitements (insuffisance rénale, risque hémorragique). Conclusion. Dans notre bassin géographique, la mise en place d'un réseau cardiologie urgence a abouti à l'augmentation du recours à l'angioplastie primaire, conformément aux recommandations. Il n'y a pas eu d'effet sur la mortalité précoce. Un bénéfice sur la mortalité à un an est observé chez les patients qui ont bénéficié de mesures de prévention secondaire optimales / Objective. Acute myocardial infarction (AMI) annually affects more than 120 000 people in France. We studied the management of ST elevation MI (STEMI). Two reperfusion strategies are available: intravenous thrombolysis (TL) and primary percutaneous coronary intervention (PPCI). Our study aimed to evaluate the impact of these strategies in the acute phase of myocardial infarction through the establishment of an emergency network based on a shared protocol with interventional cardiology. Methods. We established a regional emergency cardiovascular network (RESCUe Network) that covers a population of 3 million inhabitants across five administrative counties, including urban and rural territories. All nineteen MICUs, thirty seven emergency departments and 10 catheterization laboratories participate in the network. We edited regularly updated guidelines, set up a doctors’ training program and implemented an evaluation registry. Results. We setup the AGIR-2 study, a multicenter, controlled, randomized study, to explore prehospital high-dose tirofiban in patients undergoing PPCI. Three hundred and twenty patients with STEMI were included over a period of 12 months. All of them received 250 mg of aspirin, 600 mg of clopidogrel and 60 IU/kg bolus of high molecular weight heparin before admission to the catheterization laboratory. If prehospital initiation of high-dose bolus of tirofiban did not improve outcome, AGIR-2 study reinforced the collaborative network between emergency medicine and interventional cardiology. Since then, PPCI has gradually become the reference reperfusion strategy for STEMI in our network. Using data from our registry, we studied STEMI patients treated in mobile intensive care units (MICUs) between 2009 and 2013. Among 2418 patients, 2119 (87.6%) underwent PPCI and 299 (12.4%) prehospital TL (94.0% of whom went on to undergo PPCI). Use of PPCI increased from 78.4% in 2009 to 95.9% in 2013 (Ptrend<0.001). Median delays included: first medical contact (FMC)–PCI centre 48 min, FMC–balloon inflation 94 min, and PCI centre– balloon inflation 43 min. Times from symptom onset to FMC and FMC to TL remained stable during 2009 to 2013, but times from symptom onset to first balloon inflation and FMC to PCI centre to first balloon inflation decreased (P<0.001). In total, 2146 (89.2%) had an FMC–PCI centre delay ≤90 min with PPCI use up to 97.7% in 2013 in accordance with guidelines. Inhospital (4–6%) and 30-day (6–8%) mortalities remained stable from 2009 to 2013. Finally, we sought to assess the effect of strict adherence to current international guidelines on 1-year all-cause mortality in a prospective cohort of patients with STEMI. After multivariable adjustment, the association between the optimal therapy (OT) group (Betablockers, Antiplatelet agents, Statins, angiotensin-converting enzyme [ACE] Inhibitors, and Correction of all risk factors) and survival remained significant, with a hazard ratio of 0.12 (95% CI 0.07–0.22; P<0.001). Of the 5161 patients discharged alive, 2991 (58%) were prescribed OT. Patients characteristics in the under treatment (UT) group were worse than those in the OT group because of contraindications to optimal treatment (renal failure, bleeding risk). Conclusion. The establishment of an emergency network in our area resulted in an increased use of PPCI in accordance with ESC guidelines with no effect on early mortality. Reduction of one year mortality was observed in patients who received optimal secondary prevention treatment
