The Changes for Ischaemic Heart Disease Mortality at the Global Level and Their Association with Natural Disaster: A 28-Year Ecological Trend Study in 193 Countries

Background: Natural disaster is considered to be associated with cardiovascular disease. This study aimed to explore the changes for ischaemic heart disease(IHD) mortality and their association between natural disaster at the global level. Methods: Country-specific data on natural disaster impact (occurrence, casualties and total damage), IHD death and years of life lost (YLL) rates and socioeconomic variables were obtained for 193 countries from open sources for the period 1990 to 2017. An ecological trend study was conducted, and correlation analysis and multivariate linear regression were used to investigate the association among the variables and identify the determinants of IHD death and YLL rates. Findings: The significant changes were found in IHD death and YLL rates, and disaster occurrence between the two periods (1990 to 2013 and 2014 to 2017) (p
