Tendencia de las tasas de hospitalización y de letalidad hospitalaria de la enfermedad cerebrovascular aguda en Aragón en el periodo 1998-2010

Incidence of cerebrovascular disease in Peru from 2015 to 2023

Cerebrovascular disease (stroke) is one of the leading causes of mortality and disability worldwide, particularly in low- and middle-income countries. This study aims to estimate the incidence of stroke in Peru between 2015 and 2023 using national hospital discharge data provided by the National Health Superintendency. We conducted a mixed ecological study using records of stroke cases reported across various healthcare systems, including the Ministry of Health, Social Security, and private entities. Hospitalizations were categorized according to ICD-10 codes (I60-I64) and stratified by age, sex, and region. Incidence rates were calculated using population projections from the National Institute of Statistics and Informatics. A total of 89,776 hospital discharges for stroke were analyzed, yielding an incidence rate of 3.11 per 10,000 persons over the study period, with a predominance in men and individuals over 60 years of age. Cerebral infarction was the most common diagnosis, particularly among those over 40 years old. Incidence varied significantly across regions, with Lima and Callao consistently exceeding the national average. The results highlight disparities in healthcare access and the need for targeted public health interventions. Our findings provide a 9-year overview of stroke in Peru, offering evidence to estimate hospital bed demand and prioritize preventive and management strategies-particularly in regions with higher vulnerability.

Has stroke mortality stopped declining in Spain?

OBJECTIVES

To analyse the changes in stroke mortality trends in Spain by autonomous community and by sex during the period 1980-2016, using joinpoint regression models.

METHODS

Mortality data were obtained from the Spanish National Statistics Institute. Crude and standardised rates were calculated for each Spanish autonomous community, and for each sex. Joinpoint analysis was used to identify the best-fitting points showing a statistically significant change in the trend.

RESULTS

Joinpoint analysis enabled us to differentiate between communities in which mortality rates showed a continuous decline throughout the study period in both sexes (Asturias, Cantabria, Castile and Leon, Ceuta, and Melilla) or in men only (Extremadura). In men, in all those communities in which changes in the trend were observed (all but Aragon, the Balearic Islands, and Murcia, where rates remained stable), we observed an initial period of decline (ranging from -3.4% in Catalonia and Extremadura, to -6.0% in Madrid) and a final period where the trends diverged: mortality rates continued to fall in Andalusia, Aragon, the Balearic Islands, and Madrid, but began to stabilise in Castile-La Mancha and Murcia and to increase in the Canary Islands. In women, in those communities where changes were observed (all but Aragon, Murcia, and the Basque Country, where rates remained stable), we observed an initial period of decline (ranging from -3.1% in Catalonia to -6.4% in Navarre) and a final period where divergent trends were observed: rates continued to decline in Andalusia, Aragon, Catalonia, Galicia, Madrid, and the Basque Country, but began to stabilise in Extremadura and Murcia and to increase in the Canary Islands.

CONCLUSIONS

Current data show that stroke mortality rates have decreased (in women in Andalusia), stabilised (in both sexes in Murcia, in men in Castile-La Mancha, and in women in Extremadura), and have even reversed (in both sexes in the Canary Islands). Further study is needed to identify the causes of these trends.

Time Trends in Intracerebral Hemorrhage Associated with Oral Anticoagulation and Its Risks Factors in Spain from 2008 to 2015

BACKGROUND

Intracerebral hemorrhage (ICH) is 7- to 10-fold higher in anticoagulated patients. Given the more extended use of oral anticoagulants, an increase in the prevalence of ICH associated with oral anticoagulation (ICH-OAC) could be expected. However, there is no previous study that assesses the time trends of ICH-OAC in Spain.

METHODS

We conducted a combined data analysis after creating a joint database of the 3 most important epidemiological studies on ICH-OAC of our country: the EPICES study (2008-2009), the TAC Registry (TR) study (2012-2013) and the TAC Registry 2 (TR2) study (2015). We finally included 65, 235, and 366 patients from the EPICES, TR, and TR2 studies, respectively.

RESULTS

We have observed a 3.73-fold increase in the crude annual incidence of ICH-OAC throughout the period of study, with proportion of ICH-OAC out of total ICH increasing from 8.4% in 2008 to 18.2% in 2015. Age, dyslipidemia, and prior antiplatelet treatment increased during the study, but we found no statistically significant differences in other risk factors for ICH-OAC.

CONCLUSIONS

The incidence of ICH-OAC is increasing in our country. It might at least be partly explained by aging of the population, with mean age at presentation being higher in the last years.

Prevalence of vascular risk factors in patients with and without type 2 diabetes mellitus admitted to hospital for stroke in the 2011-2013 period

INTRODUCTION

Stroke and type 2 diabetes mellitus (T2DM) are among the leading causes of morbidity and mortality in Europe.

OBJECTIVE

To describe the vascular risk factors most prevalent in the Spanish population with and without type 2 diabetes mellitus admitted to hospital for a stroke during the 2011-2013 period.

MATERIAL AND METHODS

Using the Spanish Minimum Basic Data Set from 2011 to 2013, a descriptive, observational epidemiological study was conducted comparing the prevalence rates of vascular risk factors in Spanish patients admitted to hospital for stroke. The sample was stratified by the presence or absence of a diagnosis of type 2 diabetes mellitus. Other variables studied included in-hospital mortality, length of hospital stay, and other clinical and sociodemographic variables.

RESULTS

Hypertension was the most prevalent vascular risk factor in all population groups. Female sex, age, and T2DM had a statistically significant association (p<0.05) to hospital mortality in stroke.

CONCLUSIONS

Hypertension was the most common vascular risk factor in the study sample, followed by hypercholesterolemia. There were no differences in prevalence of hypertension between patients with and without T2DM. However, T2DM is an independent risk factor for hospital mortality in any hospitalization for stroke.
