Abstract
BACKGROUND

Sudden death is unanticipated, non-violent death taking place within the first 24 h after the onset of symptoms. It is a major public health problem worldwide. Moreover, the effects of living at moderate altitude on mortality are poorly understood.

AIM

To retrospectively report the frequency and the main causes of sudden deaths in relation to total deaths at Asir Central Hospital, 2255 m above sea level, in the southern region of Saudi Arabia over a period of 4 years from 2013 to 2016.

METHODS

The medical records of 1821 deaths were examined and showed 353 cases (19.4%) of sudden death.

RESULTS

The highest incidence of sudden death was among the elderly (51%), whereas, the lowest was among children and adolescents (6.5%). With regard to gender, the incidence of sudden death was higher in males (54.4%) compared to 45.6% in females. In this study, we found that the most common direct causes of sudden death were cardiovascular diseases (29.2%), respiratory disease (22.7%), infectious disease (12.2%), cancer (9.4%) and hematological diseases (6.2%). With respect to seasonal variation, the highest incidence was during winter (31.32%) followed by summer (25.8%).

CONCLUSION

The results of this study will help emergency physicians and health care providers to exercise due care to reduce the incidence of sudden death and raise public awareness about the impact of sudden death.

Core Tip: The effects of living at moderate altitude on mortality are poorly understood. Moreover, it has been argued that living at moderate altitudes could be more protective against the development of diseases than living at high altitudes. These reported associations on the incidence and mortality of various diseases with different lifestyles at distinct altitude levels still need further investigation. Indeed, wide-scale comparisons between different altitudes as well as sea level will help to address the impact of high altitude on the incidence and mortality of various diseases. The results of this study will help emergency physicians and health care providers to exercise due care to reduce the incidence of sudden death.
