RESUMO

Objetivo. Analizar la evolución de las características epidemiológicas de las visitas atendidas de forma consecutiva en una unidad de dolor torácico (UDT) de un servicio de urgencias hospitalario (SUH) durante un periodo de 10 años. Método. Se incluyeron todas las visitas por dolor torácico no traumático (DTNT), analizándose la evolución temporal de las características epidemiológicas, de la clasificación diagnóstica inicial (evaluación clínica inicial y electrocardiograma) y final (al alta de la UDT), y los tiempos necesarios para alcanzar las mismas. Resultados. Se incluyeron 34.552 pacientes consecutivos con una edad media 59 (DE: 13) años, el 42% mujeres. Se observó un incrementó en el número anual de visitas a la UDT (p < 0,001), menor afluencia los meses de verano (p < 0,001), y mayor los días laborables (p < 0,001) y de 8-16 horas (p < 0,001). Se comprobó que progresivamente más pacientes eran mujeres (+0,29% anual, p < 0,05), menores de 50 años (+0,92%, p < 0,001), con más factores de riesgo cardiovascular, menos antecedentes de cardiopatía isquémica y con DTNT menos sugestivo de síndrome coronario agudo (SCA). La clasificación diagnóstica inicial y final descartó SCA en un 52,2% y un 80,4% de pacientes, respectivamente, hecho que aumentó progresivamente durante el periodo evaluado (+1,86%, p < 0,001; y +0,56%, p = 0,04; respectivamente). El tiempo de clasificación inicial no se modificó, pero se incrementó el necesario para la clasificación final (p < 0,001), que resultó superior en pacientes con diagnostico final de SCA (p < 0,001). Conclusión. Se observa un mayor uso de la UDT tras su creación, causado por un incremento de pacientes con DTNT de características no típicamente coronarias, disminuyendo el porcentaje de clasificados inicial y finalmente como debidos a SCA


Objective. To analyze changes in the characteristics of consecutively treated patients attended in the chest pain unit of a hospital emergency department over a 10-year period. Methods. All patients presenting with nontraumatic chest pain (NTCP) were included. We analyzed changes over time in epidemiologic characteristics, initial diagnostic classification (on clinical and electrocardiographic evaluation), final diagnosis (on discharge), and time until these diagnoses. Results. A total of 34 552 consecutive patients with a mean (SD) age of 59 (13) years were included; 42% were women. The annual number of visits rose over time. Visits were fewer in summer and more numerous on workdays and between the hours of 8 AM and 4 PM (P<.001, both comparisons). The number of women increased over time (up 0.29% annually, P<.05) as did the number of patients under the age of 50 years (up 0.92% annually, P<.001). With time, patients had fewer cardiovascular risk factors and less often had a history of ischemic heart disease. Fewer cases of NTCP had signs suggestive of acute coronary syndrome (ACS). ACS was ruled out at the time of initial and final diagnoses in 52.2% and 80.4%, respectively, and these percentages which rose over the 10-year period by 1.86% (P<.001) and 0.56% (P=.04). Time to initial diagnosis did not change. However, time to final diagnosis did increase (P<.001), and the delay was longer in patients diagnosed with ACS (P<.001). Conclusions. The chest pain unit was more active at the end of the period, in keeping with the increase in patients with NTCP whose characteristics were not typical of coronary disease. The percentages of patients initially and finally diagnosed with ACS decreased with time

RESUMO

BACKGROUND: More than 60% of patients with hypertension included in morbidity and mortality trials needed >or=2 drugs to achieve a substantial, sustained reduction in blood pressure. Tolerable combinations using higher doses of antihypertensive drugs are frequently required to control blood pressure. OBJECTIVE: The goal of this study was to assess the effect of a once-daily fixed combination of irbesartan 300 mg/hydrochlorothiazide (HCTZ) 25 mg on the circadian blood pressure profile in patients with essential hypertension that was not controlled with full-dose single therapy or low-dose combined therapy. METHODS: Study patients were recruited consecutively from the outpatient hypertension clinics of 3 university hospitals in Spain. After a 1-week washout period, patients with a mean daytime blood pressure >135/85 mm Hg were treated with irbesartan 300 mg/HCTZ 25 mg once daily for 12 weeks. Twenty-four-hour ambulatory blood pressure monitoring was performed at the end of the washout period and during the last week of treatment. RESULTS: Fifty-seven patients with essential hypertension (28 men, 29 women) were enrolled; their mean (SD) age was 60.4 (7.2) years (range, 45-78 years). After treatment, a significant reduction in both clinic and ambulatory mean (SD) blood pressure values was observed in the whole group of 57 patients (from 146.0 [11.0] mm Hg to 123.3 [13.3] mm Hg, P < 0.001 for 24-hour systolic blood pressure [SBP]; from 89.9 [8.2] mm Hg to 76.5 [9.4] mm Hg, P < 0.001 for 24-hour diastolic blood pressure [DBP]. The mean lowering of ambulatory SBP and DBP at peak was 25.2 (14.5) mm Hg and 14.7 (9.5) mm Hg, respectively, and at trough, 22.3 (18.3) mm Hg and 12.3 (10.9) mm Hg. The trough-to-peak ratio of the group was 0.92 for SBP (0.97 in responders) and 0.84 for DBP (0.89 in responders). The smoothness index, calculated as the mean of all individual values, was 1.7 (1.0) for SBP (1.8 [0.9] in responders) and 1.3 (0.8) for DBP (1.5 [0.6] in responders). Seven side effects in 6 patients were reported. No metabolic changes were observed, and no patient discontinued the study because of treatment-related adverse effects. CONCLUSIONS: The fixed combination of irbesartan 300 mg/HCTZ 25 administered once daily produced a crude meaningful effect in reducing 24-hour blood pressure and was well tolerated. The circadian profile was preserved, as shown by trough-to-peak ratios and smoothness index values for both SBP and DBP.
