This study described the trend and distribution of coronary heart disease (CHD)
in the Hexi Corridor region of Gansu. The CHD mortality rates from
2006–2015 were obtained through the Death Reporting System of Gansu Centers for
Disease Control (CDC) for 2006–2015. The overall mortality rate of CHD in the
Hexi Corridor showed a decreasing trend, increasing in winter and spring and
lowest in summer. The CHD mortality rate was higher in men than in women
(P 0.05) and increased with age (P 0.05). The mortality
rate was higher in rural areas than in urban areas (P 0.05). A
ten-year mortality rate trend analysis showed that CHD mortality rate in women
has significantly decreased. Specifically, women aged 18–39 years experienced
increased There was little change in CHD mortality among women aged 40–59 years,
and a declined in CHD mortality among women 60 years and older and women in urban
areas.
Further analysis showed that in the 18–39-year-old and 40–59-year-old groups
and in urban areas, CHD mortality rate was higher in men than in women
(P 0.05). From 2006 to 2015, the mortality rate of CHD in the Hexi
Corridor of Gansu was lower than in the national average, but in certain
populations such as men, young and middle-aged group and rural areas, the CHD
mortality rate was gradually increased. There has been a gradual and progressive
decline in CHD mortality rate compared to the rising trend in China. This is due
to fewer risk factors in the region, effective drug treatment and improvements in
environmental pollution. However, there is still a need to enhance the experience
of effective prevention and control for specific subgroups such as men, young
people and rural residents, and to take appropriate measures to prevent the
occurrence of CHD.
