BackgroundThe sex difference trend of short-term mortality in coronary artery disease (CAD) is narrowing, which has been reported in the previous studies. However, no studies assess the sex difference temporal trends of CAD mortality in China especially long-term mortality trend.MethodsBased on the registry at Guangdong Provincial People's Hospital which is the largest cardiovascular center in South China, this retrospective cohort study included 24,432 hospitalized patients with CAD confirmed by coronary angiography from January 2007 to December 2014. Women and men were followed for 1-year and 5-year all-cause mortality.ResultsFrom 2007 to 2014, 5-year age-standardized mortality increased from 10.0 to 11.7% in men (p for trend < 0.001) and from 11.5 to 8.1% in women (p for trend = 0.99). The multivariable-adjusted hazard ratios (95% CI), which compare women with men, were from 1.02 (0.39–2.67) to 0.66 (0.39–1.12) for 1-year all-cause mortality and 1.23 (0.64–2.36) to 0.59 (0.44–0.79) for 5-year all-cause mortality (p for trend = 0.04).ConclusionOur study found that the mortality risk among men and women was similar in the 1-year prognosis of CAD, and there was no significant downward trend. In the 5-year long-term prognosis of CAD, the mortality risk among men continued to rise, while women had reached the peak, which means that the mortality risk continues to be higher among men than women.
