    Chronic kidney disease (CKD) is associated with incident cardiovascular morbidity and mortality. Whether subclinical cardiovascular disease and target organ damage is associated with incident CKD is unknown. We investigated the relations of echocardiographic left ventricular mass (LVM) with incident CKD. We evaluated 2258 Framingham Offspring cohort participants (mean age, 57 years; 56% women) who underwent echocardiography at a routine examination and had an estimated glomerular filtration rate ≥60 mL/min per 1.73 m2. We used Cox proportional hazards regression with discrete time intervals to relate sex-standardized LVM (independent variable) to the incidence of CKD, defined as estimated glomerular filtration rate <60 L/min per 1.73 m2, on follow-up. During a median follow-up of 14.6 years, 373 (16.5%) participants developed incident CKD. Higher LVM was associated with higher risk of CKD after adjusting for prevalent cardiovascular disease, body mass index, systolic blood pressure, total and HDL (high-density lipoprotein) cholesterol, antihypertensive medication, smoking, and diabetes mellitus (hazard ratio, 1.15 [95% CI, 1.03-1.29]; P=0.017) per 1-SD increase in LVM g/m2. Further adjustment for baseline estimated glomerular filtration rate (adjusted hazard ratio, 1.16 [95% CI, 1.04-1.31]; P=0.010) and baseline urine albumin/creatinine ratio (adjusted hazard ratio, 1.18 [95% CI, 1.04-1.33]; P=0.009) slightly attenuated the association. In our community-based sample, LVM was associated with incident CKD prospectively, which suggests that the relations between CKD and subclinical cardiovascular disease may be bidirectional. Further studies are needed to confirm our findings.
