Tasa de mortalidad por insuficiencia cardíaca como causa básica en Chile periodo 2016-2023: Actualización epidemiológica nacional

Mortality rate from heart failure as the underlying cause in Chile 2016-2023 period. National epidemiological update

Abstract

ABSTRACT :

INTRODUCTION:

Heart failure (HF) is a clinical syndrome and a leading cause of mortality worldwide. Its main risk factors are coronary artery disease, hypertension, and diabetes. The objective of this study is to describe the mortality rate (MR) due to heart failure as an underlying cause during the period 2016 to 2023 in Chile.

MATERIALS AND METHODS:

Descriptive, observational, cross-sectional study. A descriptive analysis was conducted on TM due to HF as the underlying cause in a population aged 19 years and older during 2016–2023 in Chile (n=13,728), based on sex, age group, region, and place of death. Data were obtained from the DEIS (National Institute of Statistics and Census) and INE (National Institute of Statistics and Census). An ethics committee review was not required. No conflicts of interest were declared.

RESULTS:

The MR for the period was determined to be 13.73/100,000 inhabitants, with a steady increase in rates throughout the period. A predominance of women was observed, with an MR of 10.76; the age group over 80 had the highest MR, at 229.13, and the Valparaíso region had the highest MR, at 11.95/100,000 inhabitants.

DISCUSSION:

There is a progressive increase in TM, thus aligning with international trends, primarily associated with the aging of the population. The rise in TM in women could be associated with their longevity, with aging being one of the main risk factors. The higher TM in the 80 and older age group could be related to frailty and the increase in cardiovascular comorbidities in this population. The higher TM in the Valparaíso region could be associated with its larger elderly population.
