Patients with incident diabetes and subsequently developed chronic kidney disease had a significantly higher risk of mortality, heart failure, acute myocardial infarction, and peripheral vascular disease compared to those without CKD. The risk of mortality, heart failure, and acute myocardial infarction associated with CKD became significant soon after diabetes occurred and remained significant throughout follow-up, indicating the need for early cardiovascular care strategies for newly diagnosed diabetic patients.
Background Chronic kidney disease (CKD) introduces an increased cardiovascular risk among patients with diabetes mellitus (DM). The risk and tempo of cardiovascular diseases may differ depending upon their type. Whether CKD differentially influences the risk of developing each cardiovascular morbidity in patients with newly diagnosed DM remains unexplored. Methods We identified patients with incident DM from the Longitudinal Cohort of Diabetes Patients (LCDP) cohort (n = 429,616), and uncovered those developing CKD after DM and their propensity score-matched counterparts without. After follow-up, we examined the cardiovascular morbidity-free rates of patients with and without CKD after DM, followed by Cox proportional hazard regression analyses. We further evaluated the cumulative risk of developing each outcome consecutively during the study period. Results From LCDP, we identified 55,961 diabetic patients with CKD and matched controls without CKD. After 4.2 years, patients with incident DM and CKD afterward had a significantly higher risk of mortality (hazard ratio [HR] 1.1, 95% confidence interval [CI] 1.06-1.14), heart failure (HF) (HR 1.282, 95% CI 1.19-1.38), acute myocardial infarction (AMI) (HR 1.16, 95% CI 1.04-1.3), and peripheral vascular disease (PVD) (HR 1.277, 95% CI 1.08-1.52) compared to those without CKD. The CKD-associated risk of mortality, HF and AMI became significant soon after DM occurred and remained significant throughout follow-up, while the risk of PVD conferred by CKD did not emerge until 4 years later. The CKD-associated risk of ischemic, hemorrhagic stroke and atrial fibrillation remained insignificant. Conclusions The cardiovascular risk profile among incident DM patients differs depending on disease type. These findings can facilitate the selection of an optimal strategy for early cardiovascular care for newly diagnosed diabetic patients.
