Since the global burden of chronic kidney disease (CKD) is rising rapidly, the study aimed to assess the association of cardiovascular health (CVH) metrics with all-cause and cardiovascular disease (CVD) mortality among individuals with CKD.
The cohort study included 5834 participants with CKD from the National Health and Nutrition Examination Survey 1999-2018. A composite CVH score was calculated based on smoking status, physical activity, body mass index, blood pressure, total cholesterol, diet quality, and glucose control. Primary outcomes were all-cause and CVD mortality as of December 31, 2019. Multivariable-adjusted Cox proportional hazards models were used to estimate the association between CVH metrics and deaths in CKD patients. During a median follow-up of 7.2 years, 2178 all-cause deaths and 779 CVD deaths were documented. Compared to participants with ideal CVH, individuals with intermediate CVH exhibited a 46.0% increase in all-cause mortality (hazard ratio, 1.46; 95% confidence interval: 1.17, 1.83), while those with poor CVH demonstrated a 101.0% increase (2.01; 1.54, 2.62). For CVD mortality, individuals with intermediate CVH experienced a 56.0% increase (1.56; 1.02, 2.39), and those with poor CVH demonstrated a 143.0% increase (2.43; 1.51, 3.91). Linear trends were noted for the associations of CVH with both all-cause mortality (P for trend <0.001) and CVD mortality (P for trend = 0.02).
Lower CVH levels were associated with higher all-cause and CVD mortality in individuals with CKD, which highlights the importance of maintaining good CVH in CKD patients.
鉴于全球慢性肾脏病（CKD）负担迅速上升，本研究旨在评估心血管健康（CVH）指标与CKD患者全因死亡率和心血管疾病（CVD）死亡率之间的关联。
该队列研究纳入了1999 - 2018年美国国家健康与营养检查调查中的5834例CKD患者。基于吸烟状况、身体活动、体重指数、血压、总胆固醇、饮食质量和血糖控制情况计算综合CVH评分。主要结局为截至2019年12月31日的全因死亡率和CVD死亡率。采用多变量调整的Cox比例风险模型来估计CKD患者中CVH指标与死亡之间的关联。在中位随访7.2年期间，记录到2178例全因死亡和779例CVD死亡。与具有理想CVH的参与者相比，具有中等CVH的个体全因死亡率增加了46.0%（风险比，1.46；95%置信区间：1.17，1.83），而具有较差CVH的个体则增加了101.0%（2.01；1.54，2.62）。对于CVD死亡率，具有中等CVH的个体增加了56.0%（1.56；1.02，2.39），而具有较差CVH的个体增加了143.0%（2.43；1.51，3.91）。CVH与全因死亡率（趋势P<0.001）和CVD死亡率（趋势P = 0.02）之间的关联均呈现线性趋势。
较低的CVH水平与CKD患者较高的全因死亡率和CVD死亡率相关，这凸显了在CKD患者中维持良好CVH的重要性。
