Primary angioplasty vs. fibrinolysis in very old patients with acute myocardial infarction: TRIANA (TRatamiento del Infarto Agudo de miocardio eN Ancianos) randomized trial and pooled analysis with previous studies.

ABSTRACT: To compare primary percutaneous coronary intervention (pPCI) and fibrinolysis in very old patients with ST-segment elevation myocardial infarction (STEMI), in whom head-to-head comparisons between both strategies are scarce.Patients ?75 years old with STEMI <6 h were randomized to pPCI or fibrinolysis. The primary endpoint was a composite of all-cause mortality, re-infarction, or disabling stroke at 30 days. The trial was prematurely stopped due to slow recruitment after enrolling 266 patients (134 allocated to pPCI and 132 to fibrinolysis). Both groups were well balanced in baseline characteristics. Mean age was 81 years. The primary endpoint was reached in 25 patients in the pPCI group (18.9%) and 34 (25.4%) in the fibrinolysis arm [odds ratio (OR), 0.69; 95% confidence interval (CI) 0.38-1.23; P = 0.21]. Similarly, non-significant reductions were found in death (13.6 vs. 17.2%, P = 0.43), re-infarction (5.3 vs. 8.2%, P = 0.35), or disabling stroke (0.8 vs. 3.0%, P = 0.18). Recurrent ischaemia was less common in pPCI-treated patients (0.8 vs. 9.7%, P< 0.001). No differences were found in major bleeds. A pooled analysis with the two previous reperfusion trials performed in older patients showed an advantage of pPCI over fibrinolysis in reducing death, re-infarction, or stroke at 30 days (OR, 0.64; 95% CI 0.45-0.91).Primary PCI seems to be the best reperfusion therapy for STEMI even for the oldest patients. Early contemporary fibrinolytic therapy may be a safe alternative to pPCI in the elderly when this is not available.

Project description:En Francia, el Ministerio de Sanidad establece en su programa nacional de prevención de infecciones asociadas a la asistencia sanitaria o infecciones nosocomiales de 2015 que los centros sanitarios, así como los establecimientos médico-sociales y los médicos locales deben prevenir este tipo de infecciones. Este artículo describe la prevención de la transmisión de microorganismos procedentes de pacientes o ambientales. Dicha prevención incluye siempre la aplicación de una serie de precauciones estándar (lavado y/o desinfección de manos, uso de guantes ante el menor riesgo de contacto con líquidos biológicos, uso de batas, gafas y mascarillas si existe un riesgo de proyección o de aerosolización de sangre o de cualquier otro producto de origen humano), así como la desinfección del material y de las superficies contaminadas. En algunos casos, es preciso adoptar precauciones específicas complementarias, como las basadas en la transmisión por contacto, por ejemplo en caso de gastroenteritis, las basadas en la transmisión por gotas, en caso de infecciones pulmonares u otorrinolaringológicas, y las específicas de la transmisión aérea, en caso de tuberculosis, sarampión o varicela. El artículo describe la prevención de infecciones asociadas a intervenciones invasivas (colocación de dispositivos urinarios, dispositivos intravasculares, actos quirúrgicos) y de infecciones en piel lesionada o en orificios de ostomía. También contempla la prevención de accidentes por exposición a la sangre (AES): uso de materiales de seguridad, definición clara y escrita de la conducta necesaria ante un AES, vacunación del personal. La emergencia de la resistencia a los antibióticos es un desafío para la salud pública. El control de la difusión de bacterias multirresistentes a los antibióticos y de bacterias altamente resistentes está basado a su vez en el control de la prescripción de antibióticos y de la prevención de la difusión de infecciones a partir de pacientes portadores (transmisión cruzada).

Project description:BackgroundTotal leukocyte and differential Leukocyte counts are prognostic indictors in patients with coronary artery disease (CAD). However, there is no data available regarding their prognostic utility in very old patients with acute myocardial infarction (AMI). The aim of this study is to investigate the potential role of different leukocyte parameters in predicting the mortality among very old patients with AMI.MethodsA total of 523 patients aged over 80 years with AMI were consecutively enrolled into this study. Leukocyte and its subtypes were obtained at admission in each patient. The primary study endpoint was cardiovascular mortality. Patients were followed up for an average of 2.2 years and 153 patients died. The associations of leukocyte parameters with mortality were assessed using Cox regression analyses. The concordance index was calculated to test the model efficiency.ResultsIn multivariable regression analysis, neutrophils-plus-monocytes-to-lymphocytes ratio (NMLR) and neutrophils-to-lymphocytes ratio (NLR) were two most significant predictors of mortality among all the leukocyte parameters (HR = 3.21, 95% CI 1.75-5.35; HR = 2.79, 95% CI 1.59-4.88, respectively, all p < 0.001, adjusted for age, male gender, body mass index, family history of CAD, smoking, hypertension, diabetes mellitus, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, high sensitivity C-reactive protein, creatinine, left ventricular ejection fraction, troponin I, use of statin, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and percutaneous coronary intervention). Furthermore, adding NMLR and NLR into the Cox model increased the C-statistic by 0.038 and 0.037 respectively, which were more significant than that of other leukocyte parameters. Besides, addition of NMLR and NLR to the Canada Acute Coronary Syndrome Risk Score model also increased the C-statistic by 0.079 and 0.077 respectively.ConclusionOur data firstly indicated that most leukocyte subtypes were independent markers for the mortality in very old patients with AMI, while NMLR and NLR appeared to be more effective.
