This study aims to analyze the impact of cardiovascular and cerebrovascular diseases (CCVDs) mortality on Tianjin's life expectancy (LE) in 2004 compared with 2020 using Arriaga's decomposition method. The LE increment for Tianjin residents due to the decrease in CCVDs mortality was 1.54 years (38.7%). Males, females, urban residents, and rural residents contributed 1.29 years (36.83%), 1.76 years (40.25%), 2.11 years (44.41%), and 0.71 years (25.06%), respectively. A total of 38.2% of the LE increment was attributed to deaths from CCVDs in people aged ≥65 years. Cerebral infarction, intracerebral hemorrhage, acute myocardial infarction, and other heart diseases contributed positively to the increase in LE (24.8%, 22.68%, 16.66%, and 11.3%). Sequelae of cerebrovascular disease and other coronary heart diseases contributed negatively to the increase in LE (-25.2% and -17.92%). Therefore, we need to control the risk factors of the elderly, males, rural residents, sequelae of cerebrovascular disease, and other coronary heart diseases.
