Abstract Background To inform public health policies regarding disease management, it is crucial to comprehend the prevalence and mortality rates linked to various stages of Cardiovascular-Kidney-Metabolic (CKM) syndrome. Methods A longitudinal study was conducted using National Health and Nutrition Examination Survey (NHANES) data (1999-2018) from 50,624 U.S. adults, defining CKM syndrome stages based on the 2023 American Heart Association (AHA) Presidential Advisory Statement. The investigation aimed to assess changes in 10-and 15-year adjusted cumulative incidences of cardiovascular mortality with each CKD syndrome stage and describe the cross-sectional prevalence of CKM syndrome from 1999 to 2020. Results CKM syndrome prevalence by stage was as follows: Stage 0, 12.5% (95% CI, 12.0-12.9); Stage 1, 16.7% (95% CI, 16.2-17.2); Stage 2, 40.0% (95% CI, 38.4-39.6); Stage 3, 22.9% (95% CI, 22.5-23.4); Stage 4, 8.9% (95% CI, 8.6-9.2). Over a median 9.5-year follow-up, 2,557 participants experienced cardiovascular death. The proportion of participants in Stages 0 and 3 decreased, while Stage 1 increased. The 15-year adjusted cumulative incidences of cardiovascular mortality were: Stage 0, 4.8% (95% CI 3.1-6.6); Stage 1, 5.3% (95% CI 4.0-6.6); Stage 2, 7.9% (95% CI 8.1-10.3); Stage 3, 9.2% (95% CI 8.1-10.3); Stage 4, 15.6% (95% CI 14.7-16.6). The absolute risk difference between CKM Stage 4 and Stage 0 at 15 years was 10.8% (95% CI 8.8-12.8). Conclusions Our findings showed a graded increase in cardiovascular mortality associated with each CKM stage. The trends observed by stage prevalence emphasize critical opportunities for stabilizing risk factors, thereby preventing adverse cardiovascular outcomes.
