Papel del índice de Charlson en el pronóstico a 30 días y 1 año tras un infarto agudo de miocardio

Introduccion y objetivos.El indice de Charlson (iCh) ha sido utilizado como variable de ajuste en modelos multivariables como indicador de comorbilidad. Debido a que su valor pronostico per se para complicaciones cardiovasculares tras un infarto agudo de miocardio no ha sido ampliamente evaluado, nos propusimos determinar su valor predictivo para muerte de cualquier causa y/o reinfarto, a 30 dias y 1 ano del evento indice. Pacientes y metodo. Se incluyo a 1.035 pacientes con el diagnostico de infarto (508 con elevacion del segmento ST y 527 sin elevacion del segmento ST). La presencia de eventos se determino a 30 dias (13,9%) y a un ano (26,3%). El iCh se calculo junto con otras variables d…

Cytomegalovirus infection management in solid organ transplant recipients across European centers in the time of molecular diagnostics: An ESGICH survey

Background Scant information is available about how transplant centers are managing their use of quantitative molecular testing (QNAT) assays for active cytomegalovirus (CMV) infection monitoring in solid organ transplant (SOT) recipients. The current study was aimed at gathering information on current practices in the management of CMV infection across European centers in the era of molecular testing assays. Methods A questionnaire-based cross-sectional survey study was conducted by the European Study Group of Infections in Immunocompromised Hosts (ESGICH) of the Society of Clinical Microbiology and Infectious Diseases (ESCMID). The invitation and a weekly reminder with a personal link to …

Prognostic Value of White Blood Cell Count in Acute Myocardial Infarction: Long-Term Mortality

Although traditionally an elevated white blood cell count (WBC), an indicator of systemic inflammation, has been accepted as part of the healing response following acute myocardial infarction (AMI), it has frequently been shown to be a predictor of adverse cardiovascular events. The present study was designed to assess the association between WBC and long-term mortality in AMI patients either with ST-segment elevation (STEMI) or without ST-segment elevation (non-STEMI). Patients and method. The study included 1118 consecutive patients who were admitted with the diagnosis of AMI: 569 non-STEMI and 549 STEMI. The WBC was measured in the 24 hours following admission. Patients were divided into…

Resultados de la estrategia farmacoinvasiva y de la angioplastia primaria en la reperfusión del infarto con elevación del segmento ST. Estudio con resonancia magnética cardiaca en la primera semana y en el sexto mes

Introduction and objectives: Pharmacoinvasive strategy represents an attractive alternative to primary angioplasty. Using cardiovascular magnetic resonance imaging we compared the left ventricular outcome of the pharmacoinvasive strategy and primary angioplasty for the reperfusion of ST-segment elevation myocardial infarction. Methods: Cardiovascular magnetic resonance was performed 1 week and 6 months after infarction in two consecutive cohorts of patients included in a prospective university hospital ST-segment elevation myocardial infarction registry. During the period 2004-2006, 151 patients were treated with pharmacoinvasive strategy (thrombolysis followed by routine non-immediate angi…

Therapeutic implications of low lymphocyte count in non-ST segment elevation acute coronary syndromes

Abstract Background Low lymphocyte count (LLC), a surrogate for inflammation, has emerged as a potential risk factor for cardiovascular outcomes, especially new ischemic events. To identify patients with non-ST segment elevation acute coronary syndromes (NSTEACS) who benefit from an invasive revascularization strategy remains a challenge. We sought to determine if patients with high-risk NSTEACS who exhibited LLC have a greater reduction in long-term post-discharge myocardial infarction (MI) when managed under a revascularization invasive strategy (RIS) as compared with conservative strategy (CS). Methods Nine hundred seventy two consecutive patients with high-risk NSTEACS were treated unde…

Usefulness of C-reactive protein and left ventricular function for risk assessment in survivors of acute myocardial infarction.

The additional prognostic information provided by C-reactive protein (CRP) to parameters of left ventricular function in survivors of acute myocardial infarction (AMI) was investigated in 665 patients (326 with ST elevation and 339 with non-ST elevation). Cox multivariable analysis identified the following predictors of 6-month cardiac death: age (per 5 years hazard ratio [HR] 1.2, 95% confidence interval [CI] 1.1 to 1.4, p = 0.004), Killip class >I at presentation (HR 2.4, 95% CI 1.3 to 4.5, p = 0.0001), a reduced ejection fraction (per 5% HR 1.3, 95% CI 1.2 to 1.4, p = 0.0001), and greater CRP (per 5 mg/L HR 1.02, 95% CI 1.01 to 1.04, p = 0.02); the C-index of the model was 0.77 without a…

Prognostic Value of Charlson Comorbidity Index at 30 Days and 1 Year After Acute Myocardial Infarction

Introduction and objectives. The Charlson comorbidity index (CCI), an indicator of comorbidity, has been used as an adjusting variable in multivariate models. Because of its prognostic value per se for cardiovascular complications after acute myocardial infarction (AMI), we sought to determine the predictive value of the CCI for allcause mortality and recurrent AMI 30 days and 1 year after the index event. Patients and method. We analyzed 1035 consecutive patients admitted with the diagnosis of AMI (ST elevation=508 and non-ST elevation=527). The composite endpoint was determined after 30 days (13.9%) and 1 year (26.3%) of follow-up. The CCI was calculated on admission, and other variables …

Low rate of detection of active cytomegalovirus (CMV) infection early following acute myocardial infarction

Pronóstico a corto plazo de los pacientes ingresados por probable síndrome coronario agudo sin elevación del segmento ST. Papel de los nuevos marcadores de daño miocárdico y de los reactantes de fase aguda

Objectives. The relative value of classic markers, myocardial damage variables, and levels of acute-phase reactants in establishing the pre-discharge prognosis of acute coronary syndrome without ST-segment elevation was analyzed. Method. We prospectively studied 385 consecutive patients admitted from our chest pain unit with a highprobability diagnosis of acute coronary syndrome without ST-segment elevation. The clinical and electrocardiographic data, myocardial damage markers (troponin I, CK-Mb mass, myoglobin), and acute-phase reactants (high-sensitivity C-reactive protein, fibrinogen) were recorded. Results. During admission, 15 deaths (3.9%) and 16 complicative infarctions (4.2%) occurr…

Valor pronóstico del recuento leucocitario en el infarto agudo de miocardio: mortalidad a largo plazo

Introduccion y objetivos. Publicaciones recientes respaldan el papel pronostico del recuento leucocitario (RL) en pacientes con infarto agudo de miocardio (IAM). El objetivo de este trabajo fue determinar el valor predictivo atribuible al RL, con independencia de otras variables de contrastado valor pronostico, para predecir mortalidad a largo plazo en pacientes con IAM sin elevacion del segmento ST (IAMSEST) y con elevacion del segmento ST (IAMEST). Pacientes y metodo. Analizamos a 1.118 pacientes admitidos de forma consecutiva con el diagnostico de IAM (IAMSEST = 569; IAMEST = 549). El RL se obtuvo en la primera determinacion analitica. Se utilizaron modelos de regresion de Cox para deter…
