Hospital Mortality in 415 798 AMI Patients: 4 Years Earlier in the Canary Islands Than in the Rest of Spain.

INTRODUCTION AND OBJECTIVES: The Canary Islands has the highest mortality from diabetes in Spain. The aim of this study was to determine possible differences in mortality due to acute myocardial infarction (AMI) during hospital admission between this autonomous community and the rest of Spain, as well as the factors associated with this mortality and the population fraction attributable to diabetes. METHODS: Cross-sectional study of hospital admissions for AMI in Spain from 2007 to 2014, registered in the Minimum Basic Data Set. RESULTS: A total of 415 798 AMI were identified. Canary Island patients (16 317) were younger than those living in the rest of Spain (63.93 ± 13.56 vs 68.25 ± 13.94; P < .001) and death occurred 4 years earlier in the archipelago (74.03 ± 11.85 vs 78.38 ± 11.10; P < .001). This autonomous community had the highest prevalence of smoking (44% in men and 23% in women); throughout Spain, AMI occurred 13 years earlier in smokers than in nonsmokers. Patients in the Canary Islands had the highest mortality rates whether they had diabetes (8.7%) or not (7.6%), and they also showed the highest fraction of AMI mortality attributable to diabetes (9.4; 95%CI, 4.8-13.6). After adjustment for type of AMI, diabetes, dyslipidemia, hypertension, smoking, cocaine use, renal failure, sex and age, the Canary Islands showed the highest risk of mortality vs the rest of Spain (OR = 1.25; 95%CI, 1.17-1.33; P < .001) and it was one of the autonomous communities showing no significant improvement in the risk of mortality due to AMI during the study period. CONCLUSIONS: Mortality due to AMI during hospital admission is higher in the Canary Islands than in the rest of Spain.

Mortalidad hospitalaria de 415.798 pacientes con IAM: 4 años antes en Canarias que en el conjunto de España / Hospital mortality in 415 798 AMI patients: 4 years earlier in the Canary Islands than in the rest of Spain

Introducción y objetivos: Canarias tiene la mortalidad por diabetes más elevada de España. El objetivo es averiguar si existen diferencias con las restantes comunidades autónomas en la mortalidad hospitalaria por infarto agudo de miocardio (IAM), en los factores asociados con esta mortalidad y la fracción poblacional atribuible a la diabetes. Métodos: Estudio descriptivo de los ingresos hospitalarios por IAM en España desde 2007 hasta 2014, registrados en el Conjunto Mínimo Básico de Datos. Resultados: Se identificaron 415.798 IAM. Los pacientes canarios (16.317) eran más jóvenes que los del resto de España (63,93 +/- 13,56 frente a 68,25 +/- 13,94 años; p < 0,001); también el fallecimiento ocurrió 4 años antes en el archipiélago (a los 74,03 +/- 11,85 frente a los 78,38 +/- 11,10 años; p < 0,001). En esta comunidad alcanzó su prevalencia máxima el tabaquismo (el 44% de los varones y el 23% de las mujeres), que se asoció con un adelanto de 13 años en la edad al IAM. Las islas Canarias tuvieron la mayor mortalidad de pacientes tanto con diabetes (8,7%) como sin ella (7,6%), y también la mayor fracción poblacional de muerte por IAM atribuible a la diabetes (9,4; IC95%, 4,8-13,6). Tras ajustar por tipo de IAM, diabetes, dislipemia, hipertensión, tabaquismo, consumo de cocaína, insuficiencia renal, sexo y edad, Canarias presentó el mayor riesgo de mortalidad respecto a España (OR = 1,25; IC95%, 1,17-1,33; p < 0,001). Fue, además, una de las comunidades autónomas que no mejoró significativamente su riesgo demortalidad por IAM durante el periodo estudiado
