Abstract The cardiovascular-kidney-metabolic (CKM) syndrome consists of four progressive stages and is characterized by the interaction of metabolic risk factors, chronic kidney disease (CKD), and cardiovascular disease (CVD). We assessed the prevalence of hypertension in CKM and its role in progression to more advanced stages. We included 2118 Black adults from the Jackson Heart Study without a history of coronary heart disease, heart failure, stroke or stage 0 CKM (normal weight, no metabolic risk factors or CVD) at baseline. Participants were categorized into CKD stage: Stage 1: overweight/obesity, abdominal obesity or dysfunctional adipose tissue without metabolic risk factors or subclinical CVD; Stage 2: metabolic risk factors (hypertension, diabetes, hypertriglyceridemia, metabolic syndrome or CKD); or Stage 3: subclinical CVD. We used Cox proportional hazards regression to estimate the hazard ratio (HR) of developing stage 4 CKM, defined by a CVD event, in participants with hypertension and stages 2 and 3 CKM. At baseline, 20.2, 69.1 and 10.6% of participants had stage 1, 2 and 3 CKM, respectively. Hypertension was the most common metabolic risk factor in participants with stage 2 and 3 CKM with a prevalence of 80 and 95%, respectively. Incidence rates (95%CI) of stage 4 CKM per 1000 person-years were 1.4 (0.4, 2.4) for stage 1 CKM, 7.5 (6.1, 8.9) for stage 2 CKM with hypertension, and 26.6 (19.8, 33.3) for stage 3 CKM with hypertension. The HRs (95% CI) for developing stage 4 CKM were 3.25 (1.56, 6.80) and 5.11 (2.05,12.78) among participants with hypertension and stage 2 and 3 CKM versus stage 1 CKM, respectively. Hypertension was associated with an increased risk for progression to stage 4 CKM among Black adults.
