Disección coronaria espontánea en España: un estudio sobre bases administrativas realizado a partir del Conjunto Mínimo Básico de Datos español / Spontaneous coronary artery dissection in Spain: a study using the minimum data set of the Spanish National Health System

Introducción y objetivos La disección coronaria espontánea (DCE) es una causa poco común de infarto agudo de miocardio (IAM). En este estudio se comparan la mortalidad y los reingresos hospitalarios de los pacientes con IAM-DCE e IAM de otras etiologías (IAM-NDCE). Métodos Se calcularon las razones de mortalidad hospitalaria y de reingresos a los 30 días estandarizadas por riesgo (RAMER y RARER respectivamente) utilizando el Conjunto Mínimo Básico de Datos del Sistema Nacional de Salud español (2016-2019). Resultados Se hallaron 806 eventos de IAM-DCE y 119.425 de IMA-NDCE. Los IAM-DCE se produjeron en pacientes más jóvenes y más frecuentemente mujeres que los IAM-NDCE. La mortalidad bruta fue menor (el 3 frente al 7,6%; p<0,001) y la RAMER, mayor (el 7,6±1,7 frente al 7,4±1,7%; p=0,019) en los IAM-DCE. Tras emparejamiento por puntuación de propensión (806 parejas), la mortalidad fue similar en ambos grupos (AdjOR=1,15; IC95%, 0,61-2,2; p=0,653). La tasa bruta de reingresos de los pacientes con IAM-DCE a 30 días fue similar (el 4,6 frente al 5%; p=0,67), mientras que la RARER fue menor (el 4,7±1 frente al 4,8±1%; p=0,015). Tras el emparejamiento por puntuación de propensión (715 parejas), la tasa de ingresos fue similar en ambos grupos (AdjOR=1,14; IC95%, 0,67-1,98; p=0,603). Conclusiones La mortalidad hospitalaria y los reingresos a los 30 días de los pacientes con IAM-DCE es similar a la de los IAM-NDCE cuando el riesgo se ajusta a las características basales de la población. Estos datos resaltan la necesidad de optimizar el manejo, tratamiento y seguimiento clínico de los pacientes con DCE (AU)

Introduction and objectives Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction (AMI). We sought to compare the results on in-hospital mortality and 30-day readmission rates among patients with AMI-SCAD vs AMI due to other causes (AMI-non-SCAD). Methods Risk-standardized in-hospital mortality (rIMR) and risk-standardized 30-day readmission ratios (rRAR) were calculated using the minimum dataset of the Spanish National Health System (2016-2019). Results A total of 806 episodes of AMI-SCAD were compared with 119 425 episodes of AMI–non-SCAD. Patients with AMI-SCAD were younger and more frequently female than those with AMI–non-SCAD. Crude in-hospital mortality was lower (3% vs 7.6%; P<.001) and rIMR higher (7.6±1.7% vs 7.4±1.7%; P=.019) in AMI-SCAD. However, after propensity score adjustment (806 pairs), the mortality rate was similar in the 2 groups (AdjOR, 1.15; 95%CI, 0.61-2,2; P=.653). Crude 30-day readmission rates were also similar in the 2 groups (4.6% vs 5%, P=.67) whereas rRAR were lower (4.7±1% vs 4.8%±1%; P=.015) in patients with AMI-SCAD. Again, after propensity score adjustment (715 pairs) readmission rates were similar in the 2 groups (AdjOR, 1.14; 95%CI, 0.67–1.98; P=.603). Conclusions In-hospital mortality and readmission rates are similar in patients with AMI-SCAD and AMI–non-SCAD when adjusted for the differences in baseline characteristics. These findings underscore the need to optimize the management, treatment, and clinical follow-up of patients with SCAD (AU)

[Prevalence of cancer in the Guadalajara health area]. / Prevalencia de cáncer en el área de salud de Guadalajara.

OBJECTIVE: To quantify the prevalence of cancerand its distribution in adults. DESIGN: Descriptive study of point prevalence through research into primary and secondary sources. SETTING: Primary care, Guadalajara Health Region. 133 539 people over 14 years old. PARTICIPANTS: Patients previously diagnosed with cancer, who had a health card in the health area in June 1999. MEASUREMENTS: Demographic and diagnostic details (location according to CIE-9, date and diagnostic method). DATA SOURCES: primary care clinical records, cancer morbidity records and attendance orders. Overall crude and adjusted rates, in function of sex and age group, and specific to locations, were calculated. They were compared with data from other studies and data calculated for Spain on the basis of WHO information. RESULTS: 2717 tumours (2595 patients). Mean age, 68.2 (95% CI, 67.6-68.7); diagnostic age, 62.8 (95% CI, 62.1-63.5), in both cases higher in men (P<.01). Most common tumours: prostate, bladder, colon and lung (men); breast, colon, endometrium and ovaries (women). Crude prevalence: men, 2303.8/100 000; women, 1763.8. Adjusted to world population: 1394.2 and 1227.4/100 000, respectively (prevalence ratio, 1.14; 95% CI, 1.03-1.25). Truncated rate higher in women than in men (1638/100 000 against 1308). Five-year period with highest prevalence: 75-79 years old in men (8763.5/100 000) and 80-84 in women (4558.7/100 000). CONCLUSIONS: Cancer prevalence in adults is slightly above 2%. Once adjusted for age, values are similar to other studies and as expected for our country. The most common tumours are in the digestive apparatus, breast and the genito-urinary system. The man/woman proportion is higher than that described in other studies.
