BACKGROUND: Ischemic Heart Diseases (IHDs) are the main causes of deaths all over the world. Since there is no comprehensive study on IHDs mortality rate in Iran, the present study aimed to estimate age-standardized IHDs mortality rate by sex, age, geography, and time trends at both national and sub-national levels in Iran.
METHODS: We used the Death Registration System (DRS) data from 1990 to 2015 collected by the Iranian Ministry of Health and Medical Education across the country, Tehran, and Isfahan main cemetery, not included in the DRS. Utilized death distribution methods to overcome the incompleteness of data. Statistical models including Spatio-temporal and Gaussian-Process Regression models were used to extrapolate all-cause and cause-specific mortality rates.
RESULTS: Age-standardized IHDs mortality rate in Iran almost doubled from 1990 to 2015. Forty-nine deaths per 100.000 population in 1990, which increased to 91.6 deaths per 100.000 in 2015). Male to female age-standardized mortality rate increased from 1.07 to 1.32 during the studied period. Aging was associated with an increase in age-standardized IHDs mortality rate in both sexes, all provinces, and all of the years. The range of age-standardized IHDs mortality rate for both sexes was from 58 to 136.2 deaths per 100,000 across provinces in 2015.
CONCLUSION: Due to the increase in age-standardized IHDs mortality rate in Iran, it seems necessary to design and implement appropriate public health interventions by health authorities to prevent and control this group of diseases.
