[Clinical characteristics and care times in a chest pain unit of the emergency department of an argentine center]. / Características clínicas y tiempos de atención en una unidad de dolor torácico del servicio de emergencias de un centro argentino.

Objectives: . To report the frequency of precordial pain, describe clinical characteristics, and care times. Methods: . Retrospective descriptive study that included consultations in the Chest Pain Unit in 2021 in the emergency department of a private hospital in Argentina. Results: There were 1469 admissions for chest pain, yielding a frequency of 1.09% (95%CI 1.04-1.15). They were 52% men, mean age 62 years (SD ±15); 48% had hypertension and 32% dyslipidemia. The median time to initial ECG was 4.3 min (ICR 2.5-7.5); and 26 min (ICR 14-46) to medical evaluation. A total of 206 (14%) were hospitalized with a median of 3 days, 76% were admitted to a closed unit, 9% required non-invasive ventilation/mechanical ventilaction and in-hospital mortality was 2.9%. Those hospitalized presented shorter delay time to medical attention (p<0.01), and greater performance of complementary studies (p<0.01), with no differences in time to ECG (p=0.22). Conclusions: Care times were within the stipulated standards, being an important indicator of quality. Nursing was crucial, taking care of the correct triage, ECG on admission, and guaranteeing care until medical evaluation.

Hospitalization for venous thromboembolic disease management: a 10 years Registry in Buenos Aires, Argentina.

Venous thromboembolism (VTE) is the most frequent cause of preventable mortality in hospitalized patients and the third leading cause of mortality due to vascular diseases. We aim to describe patients with VTE who required hospitalization, their clinical characteristics, management and evolution after discharge. Prospective cohort which included patients with acute and symptomatic VTE who required hospitalization in a single tertiary center for their management in a 10 years´ period (between 2006 and 2016). Patients were included at the time of VTE diagnosis; we collected baseline characteristics, risk stratification and initial therapeutic approach. They were periodically, prospectively and systematically followed up to evaluate recurrence, bleeding and/or death. Time-to-event analysis was performed for these outcomes related to evolucion after discharge. 3457 confirmed VTE episodes were included for the analysis (1985 DVT, 930 PE and 542 DVT + DVT), corresponding to 3157 patients. Most were elderly, the median age was 68 years (SD 16) with a predominance of women 57% (1955). Most frequent predisposing factors were immobility (45%), active cancer (35%), recent surgery (33%), obesity (26%), recent hospitalization (22%) and previous VTE (21%). One-fourth of pulmonary embolism had sPESI 0 points. Mortality, recurrence and bleeding rates within 30 days were 14%, 10% and 5% respectively. High proportion of VTE require hospitalization for their management, even PE with low sPESI. Mortality and complication remain elevated. We encourage the development and maintenance of more VTE registries in Latin America, to fully understand local characteristics of this disease.
