ABSTRACT
OBJETIVOS: El objetivo de este estudio es medir la accesibilidad al sistema sanitario de los pacientes diabéticos y analizar si las posibles diferencias en la accesibilidad explican la mayor mortalidad conocida en aquellos. MÉTODOS: Estudio de cohortes retrospectivo, realizado en pacientes diabéticos con síndrome coronario agudo con elevación del segmento ST incluidos en los años 2010 al 2013 del registro ARIAM-SEMICYUC. Se realiza análisis crudo y ajustado mediante regresión logística no condicional. RESULTADOS: Se han analizado 4817 pacientes, de los cuales 1070 (22,2%) son diabéticos. Los pacientes diabéticos contactan con el sistema sanitario de la misma forma que los pacientes no diabéticos aunque con mayor retraso (retraso atribuible al paciente 90 min vs. 75 min con p = 0,004 y retraso prehospitalario 150 min vs. 130 min con p = 0,002). Una vez dentro del sistema sanitario, estos pacientes tienen menor tasa de reperfusión (50 vs. 57,7%; p < 0,001) pero sin objetivar mayor retraso en el tratamiento. Como ya es conocido, los pacientes diabéticos presentan una mayor mortalidad hospitalaria (12,5 vs. 6%; p < 0,001); sin embargo, no se identifican como variables predictoras independientes de la mortalidad ni el retraso atribuible al paciente ni el retraso prehospitalario. CONCLUSIONES: Los pacientes diabéticos tienen una mayor demora en el acceso al sistema sanitario, sin embargo no hemos podido objetivar que esta demora se relacione de forma independiente con la mayor mortalidad
OBJECTIVES: To measure accessibility to health care among diabetic patients and analyze whether differences in delay explain differences in hospital mortality. METHODS: A retrospective cohort study was conducted in diabetic patients with acute coronary syndrome with ST-segment elevation included in the ARIAM-SEMICYUC registry (2010-2013). Crude and adjusted analyses were performed using unconditional logistic regression. RESULTS: A total of 4817 patients were analyzed, of whom 1070 (22.2%) were diabetics. No differences were found in access to health care between diabetic and non-diabetic patients. Diabetic patients presented with longer patient delay (90 min vs. 75 min; p = .004) and prehospital delay (150min vs. 130 min; p = .002). Once the health system was contacted, diabetic patients had a lower reperfusion rate (50% vs. 57.7%; p < .001), but no longer delay in treatment was observed compared with the non-diabetic individuals. Diabetic patients have greater in-hospital mortality (12.5 vs. 6%; p < .001), though neither patient delay nor prehospital delay were identified as independent predictors of in-hospital mortality. CONCLUSIONS: Diabetic patients had a longer delay in access to health care, though such delay was not independently related to increased mortality

BACKGROUND: Whereas the significance of right bundle-branch block (RBBB) in acute myocardial infarction was extensively studied in the prethrombolytic era, a possible change in the overall incidence and meaning of RBBB as a consequence of thrombolytic therapy is not well known. METHODS AND RESULTS: A multicenter, prospective study of 1238 patients consecutively diagnosed with acute myocardial infarction and admitted to three coronary care units was conducted. ECGs during the acute phase and clinical events until discharge and 1-year follow-up were monitored. In the 135 (10.9%) patients in whom RBBB was found, there were 51 (37.8%) new cases, 46 (34.1%) old cases, and 38 (28.1%) cases with an indeterminate time of origin. New RBBB was permanent in 26 and transient in 25 patients. RBBB was isolated in 76 (56%) and bifascicular in the remaining 59 (44%) patients. The following complications were more frequently associated with RBBB than non-RBBB patients: heart failure, 24% versus 46% (P<.001); use of pacemaker because of atrioventricular block, 3.6% versus 11% (P<.001); and 1-year mortality, 17.6% versus 40.7% (P<.001). Early mortality was significantly higher for new RBBB (43.1%, P<.001) than for old (15.5%) and indeterminate (15.3%) RBBB. These figures for 1-year mortality were 58.8% (P<.001), 35.5 (P<.01), and 23% (NS), respectively. Permanent and transient RBBB had different mortality rates: early mortality, 76% versus 8%, and 1-year mortality, 84% versus 32% (P<.001 for both). For isolated RBBB versus bifascicular block, early mortality was 14.4% versus 40.6%, and 1-year mortality was 30.2% versus 54.2% (P<.05 for both). Multivariate analysis showed an independent prognostic value of RBBB for early and 1-year mortality. CONCLUSIONS: The overall meaning of RBBB in acute myocardial infarction has not changed in the thrombolytic era, although a higher rate of new and transient RBBB and a lower rate of bifascicular block may represent a beneficial effect of thrombolytic therapy.

Four patients admitted to our hospital with different symptomatology are studied: a 9-years-old boy with hyperhidrosis; a 47-years-old woman with arterial hypertension and two young males, 25 and 36-years-old, respectively, with thoracic pain. In all cases, the presence of pheochromocytoma was suspected. One of them died due to left ventricular failure with acute lung edema. The other three patients were diagnosed by hormonal determinations, detecting a supra-renal body with abdominal echography and computerized axial tomography and undergoing surgery. Currently, they are asymptomatic.
