RESUMO

RESUMEN Introducción: En el Hospital General Docente "Dr. Octavio de la Concepción y de la Pedraja" de Baracoa, Guantánamo, hasta la fecha, no se ha caracterizado la morbilidad y mortalidad por infarto agudo del miocardio. Objetivo: Caracterizar la morbilidad y mortalidad por infarto agudo del miocardio en el citado hospital durante el trienio 2017-2019. Método: Se hizo un estudio descriptivo, retrospectivo y de corte transversaldel total de pacientes infartados en el trienio 2017-2019 (n=75). Se estudió la edad, sexo, características del infarto (semiología del dolor, localización, clasificación pronóstica-clínica, complicaciones, estado al egreso y causas de muerte). Resultados: El 72,0 % de los pacientes fueron hombres y el 37,3 % tenía 50 y 59 años de edad. La letalidad representó el 14,7 %. Fue más común el infarto anterior del ventrículo izquierdo (53,4 %). El 28,0 % presentó una clase IV, según criterios de Killip-Kimball y de Forrester. El 49,3 % mostró alto riesgo según la escala GRACE. El 88,0 % tuvo complicaciones, la más común del tipo mecánica (60,0 %). La encefalopatía isquémica-hipóxica posparada cardiorrespiratoria secundaria a fibrilación ventricular (54,5 %) fue la causa directa de muerte más frecuente. Conclusiones: Se elabora un referente que describe el infarto agudo del miocardio en el contexto territorial.


ABSTRACT Introduction: Morbidity and mortality by myocardial infarction has not been characterized so far in the General Teaching Hospital "Dr. Octavio de la Concepcion y la Pedraja" in Baracoa, Guantanamo. Objective: Tocharacterize the morbidity and mortality by myocardial infarction on the institution in the triennium 2017-2019. Method: A descriptive, retrospective and cross-sectional study was carried out in the patients diagnosed with infarction in the triennium 2017-2019 (n=75). Were taken into account the following variables: age, gender, clinical characteristics of infarction (painful symptoms, location, prognostic and clinical classification, complications, status of the patient at the time of discharge and cause of death). Results: 72.0 % of the patients were male, and the 37.3 % had an age ranging from 50 to 59 years old. Lethality represented a 14.7 %. The anterior left ventricle wall infarction was the most common (53.4 %). 28.0 % presented a class IV type, according to the Killip-Kimball and the Forrester classifications. 49.3 % presented high risks according to the GRACE score. 88.0 % had complications, the most common of them being the mechanical type (60.0 %). The most common cause of death was the hypoxic-ischemic encephalopathy caused by secondary atrial fibrillation (54.5 %). Conclusions: A reference to describe the myocardial infarction in the province was elaborated.

RESUMO

AIMS: The aim of the study is to validate at the biochemical level (presence of myocardial damage) the discharge diagnosis code ICD-9-CM 410.x1, and to compare the acute myocardial infarction (AMI) epidemiology based on pure administrative data with the epidemiology based on troponin and clinical data. METHODS: The health-related administrative databases of the Italian Region Friuli Venezia Giulia were used as the source of information. All the databases are anonymous and can be linked with each other at the individual patient level through a univocal stochastic key. Two methods were used to assess incidence in 2017: the first used the main hospital discharge diagnosis, validated by biochemical myocardial necrosis; the second identified from the cohort of all patients with any myocardial injury those with ischemic origin. RESULTS: The positive-predictive value of the clinical diagnosis of AMI (410.x1), validated at the biochemical level, was 96.2%.About 40% of patients with a not trivial biochemical myocardial injury and an ischemic heart disease diagnosis (e.g. 411) were discharged without either ST-elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI) diagnosis, leading to a sensitivity of clinical discharge diagnosis of 47.6%.Thirty-day and 90-day mortality at multivariate analysis resulted respectively, 1.8 and 4.0% in NSTEMI, 6.6 and 9.8% in STEMI, 8.8 and 12.2% in patients with biochemical AMI and discharge diagnosis other than 410.x1. CONCLUSION: Pure administrative data (clinical discharge diagnosis) are today insufficient to catch the whole hospital epidemiology of myocardial infarction missing an important proportion of AMI with an adverse prognosis comparable with STEMI.

RESUMO

BACKGROUND: The currently used scheme for the classification of infarct location and extent in anterior myocardial infarction (MI) is intuitive rather than being evidence-based, and recent evidence suggests that it may be misleading both in anatomic and prognostic sense. MATERIAL AND METHODS: Consecutive patients with the diagnosis of anterior MI were enrolled. All electrocardiograms (ECG) were first classified according to established scheme and then reassessed using newer criteria for angiographic site of occlusion. The site of left anterior descending (LAD) occlusion was determined using multiple angiographic views. Clinic, echocardiographic and angiographic outcomes were compared. RESULTS: A total of 379 anterior MI cases were enrolled, final study population consisted of 267 patients. The established scheme did not predict infarct size or adverse outcomes. Location of the myocardium subtended by the occluded coronary network did not match with the anatomic location as ECG classification implies. Many high-risk patients with proximal LAD were classified as "anteroseptal", whereas the majority of the patients labeled as "extensive anterior MI" had in fact distal occlusions. On the other hand, expert interpretation was fairly accurate in predicting adverse outcomes and the site of angiographic involvement. CONCLUSION: Classifying patients according to the established scheme neither gives prognostic information nor accurately localizes infarction. It should be regarded as obsolete and its use should be abandoned. Instead, the extent of infarction can be inferred from newer criteria provided by the angiographic correlation studies.

RESUMO

The inflammation-based Glasgow Prognostic Score (GPS), which involves C-reactive protein and serum albumin levels, has been reported to be a strong independent predictor of mortality in many cancers. This study aimed to investigate whether the GPS is associated with mortality in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI).In this study, 406 consecutive patients with STEMI at our emergency department (ED) who were undergoing pPCI were prospectively enrolled and assigned a GPS of 0, 1, or 2. Kaplan-Meier survival and multivariable Cox regression analyses were used to evaluate the associations between the GPS and long-term mortality.Twenty-three patients (5.7%) died at the hospital, and 37 (9.7%) died during follow-up (14.4 [9.3-17.6] months). Compared with patients with a lower GPS, those with a higher GPS had significantly higher in-hospital mortality (GPS = 0 vs GPS = 1 vs GPS = 2: 3.3% vs 6.3% vs 28.0%, P < .001), follow-up mortality (4.6% vs 14.3% vs 55.6%, P < .001), and cumulative mortality (9.6% vs 21.1% vs 71.1%, P < .001). Multivariable Cox regression analysis revealed that in patients with a GPS of 1 and 2 (versus 0), the multivariable adjusted hazard ratios (HR) for all-cause mortality were 2.068 (95% CI: 1.082-3.951, P = .028) and 8.305 (95% CI: 4.017-17.171, P < .001), respectively, after controlling for all of the confounding factors. Subgroup analysis showed that a higher GPS was associated with an increased risk of cumulative mortality in the different subgroups.The GPS on admission may be useful for stratifying the risk of adverse outcomes in patients with STEMI undergoing pPCI in the ED.

RESUMO

BACKGROUND: Grade 3 ischemia (G3I) in the 12­lead electrocardiogram (ECG) predicts poor outcome in patients with ST-elevation myocardial infarction (STEMI). The outcome of G3I in "real-life" patient cohorts is unclear. METHODS: The aim of the study was to establish the prognostic significance of grade 2 ischemia (G2I), G3I and the STEMI patients excluded from ischemia grading (No grade of ischemia, NG) in a real-life patient population. We assessed in-hospital, 30-day and 1-year mortality as well as other endpoints. RESULTS: The NG patients had more comorbidities and longer treatment delays than the two other groups. Short-term and 1-year mortality were highest in patients with NG and lowest in patients with G2I. Maximum troponin level was highest in G3I, followed by NG and G2I. In logistic regression multivariable analysis, NG was independently associated with 1-year mortality. CONCLUSIONS: NG predicted poor outcome in STEMI patients. G2I predicted relatively favorable outcome.

RESUMO

Objective: To evaluate the impact of the implementation of the Infarction Code strategy in patients with acute myocardial infarction diagnosis. Methods: Consecutive patients with ST-elevation acute myocardial infarction ≤12 hours of evolution, were included in the infarction code strategy, before (Group I) and after (Group II). Times of medical attention and major cardiovascular events during hospitalization were analyzed. Results: 1227 patients were included, 919 men (75%) and 308 women (25%) with an average age of 62 ± 11 years. Among Group I and Group II, percutaneous coronary intervention reperfusion therapy changed (16.6% to 42.6%), fibrinolytic therapy (39.3% to 25%), and patients who did not receive any form of reperfusion therapy (44% to 32.6%; p < 0.0001). Times of medical attention decreased significantly (door-to-needle time decreased from 92 to 72 minutes, p = 0.004; door-to-balloon time decreased from 140 to 92 minutes, p < 0.0001). Kidney failure (24.6% vs. 17.9%; p = 0.006), major complications (35.3% to 29.3%), and death (21% vs. 12%; odds ratio: 0.52; 95% confidence interval: 0.38-0.71; p = 0.004). also decreased. Conclusion: The Infarction Code strategy improved treatment, times of medical attention and decreased complications and death in these patients.

RESUMO

BACKGROUND: There is conflicting information regarding the association between hyperuricemia and survival in STEMI patients. Our study examined the interaction between hyperuricemia and Killip class on mortality of STEMI patients. METHODS: We analyzed 951 consecutive STEMI patients between February 2006 and September 2012. Hyperuricemia was defined as SUA of at least 7mg/dL in males and 6mg/dL in females. Killip class I patients were divided into hyperuricemia and normouricemia groups. RESULTS: The Killip class I hyperuricemia and normouricemia groups had similar baseline and procedural characteristics, but the hyperuricemia group had significantly greater BMI, serum creatinine, and SUA, and a lower TIMI risk score (2, IQR: 1-4 vs. 3, IQR: 2-4, p=0.019). The hyperuricemia group also had greater 30-day and 1-year mortality rates (2.9% vs. 0.3%, p=0.022; 6.5% vs. 1.1%, p=0.002, respectively). However, hyperuricemia was not associated with mortality of patients in Killip classes II-IV or in the overall study population. Hyperuricemia was associated with increased mortality in subgroups of patients who were at least 65years-old, male, had BMI of 25kg/m2 or less, were in Killip class I, without diabetes, and who did not receive intra-aortic balloon pump support. Hyperuricemia interacted with Killip class I in increasing the risk for 1-year mortality (p for interaction=0.038). CONCLUSIONS: Hyperuricemia increased the 1-year mortality of STEMI patients in Killip class I, but not of patients in Killip classes II-IV. An interaction of hyperuricemia and Killip class significantly affects the mortality of STEMI patients.

RESUMO

BACKGROUND: The role of J-waves in the pathogenesis of ventricular fibrillation (VF) occurring in structurally normal hearts is important. METHODS: We evaluated 127 patients who received an implantable cardioverter-defibrillator (ICD) for Brugada syndrome (BS, n = 53), early repolarization syndrome (ERS, n = 24), and patients with unknown or deferred diagnosis (n = 50). Electrocardiography (ECG), clinical characteristics, and ICD data were analyzed. RESULTS: J-waves were found in 27/50 patients with VF of unknown/deferred diagnosis. The J-waves were reminiscent of those seen in BS or ERS, and this subgroup of patients was termed variants of ERS and BS (VEB). In 12 VEB patients, the J/ST/T-wave morphology was coved, although amplitudes were <0.2 mV. In 15 patients, noncoved-type J/ST/T-waves were present in the right precordial leads. In the remaining 23 patients, no J-waves were identified. VEB patients exhibited clinical characteristics similar to those of BS and ERS patients. Phenotypic transition and overlap were observed among patients with BS, ERS, and VEB. Twelve patients with BS had background inferolateral ER, while five ERS patients showed prominent right precordial J-waves. Patients with this transient phenotype overlap showed a significantly lower shock-free survival than the rest of the study patients. CONCLUSIONS: VEB patients demonstrate ECG phenotype similar to but distinct from those of BS and ERS. The spectral nature of J-wave morphology/distribution and phenotypic transition/overlap suggest a common pathophysiologic background in patients with VEB, BS, and ERS. Prognostic implication of these ECG variations requires further investigation.

RESUMO

AIMS: The reduction of delay times as well as the rate of false alarms (FA) have become some of the main points of the different infarction networks. We propose a simple way of classifying patients derived for primary PCI (pPCI) into well-defined simple groups by colors, where we can assess real delays of each clinical presentation, define the FA and, furthermore, establish their immediate and short term prognosis. METHODS AND RESULTS: Prospective study of STEMI consecutive patients derived for pPCI during 2014. Patients were categorized into one of the 3 predesigned groups [(i) Green: diagnostic-ECG with compatible clinical presentation for pPCI; (ii) Yellow: LBBB, pacemaker rate or non-diagnostic ECG; and (iii) Red: very complex patients], always before performing the angiography in 518 patients. Delay times were highest in the Yellow group, with much longer first medical contact (FMC) to balloon time (median Green 118'; Yellow 163'; Red 130'; p<0.001) mainly due to higher times from the first medical contact to the diagnosis and team activation (median Green 30'; Yellow 70'; Red 39'; p<0.001). In the whole cohort, pPCI was performed in 80.2% of patients, with 11.9% of FA. The Green group had only a 2.5% FA rate, in contrast to the Yellow group where FA were 43.2%. CONCLUSIONS: This simple classification differentiates the 3 very clear groups in which delay times and prognosis are very different. This classification allows us to measure, evaluate and compare the performance of each of our pPCI networks with others and within different periods of times.
