The American Heart Association proposed 7 ideal cardiovascular health metrics (Life's Simple 7 [LS7]) namely, not smoking, body mass index <25 kg/m, healthy diet, moderate physical activity ≥150 min/week, total blood cholesterol <200 mg/dL, blood pressure <120/80 mmHg and fasting blood glucose <100 mg/dL. Our objective was to assess the association between these LS7 metrics and the incidence of atrial fibrillation (AF).
A total of 6,479 participants of the PREDIMED study were included. We calculated the participants' baseline LS7 index ranging 0-7 points to categorize them according to their adherence to these LS7 health metrics. Multivariable Cox regression models were used to estimate Hazard Ratios (HR) and their 95% Confidence Intervals (95% CI). After a median follow-up of 4.8 years, we identified 250 incident cases of AF. After adjusting for potential confounders, adherence to LS7 index was not associated with the incidence of AF (adjusted HR 0.90 [95% CI: 0.56-1.45] for highest vs. lowest LS7 categories). Body mass index <25 kg/m was the only health metric individually associated with a lower risk of AF (HR 0.36 [95% CI: 0.16-0.78]).
In a high cardiovascular risk Spanish population, adherence to American Heart Association's LS7 metrics was not associated with the risk of incident AF.

美国心脏协会提出了7项理想的心血管健康指标（即“生活简单7要素”[LS7]），分别为不吸烟、体重指数<25kg/m²、健康饮食、中等强度体育活动≥150分钟/周、总血胆固醇<200mg/dL、血压<120/80mmHg以及空腹血糖<100mg/dL。我们的目的是评估这些LS7指标与心房颤动（AF）发病率之间的关联。
纳入了PREDIMED研究的6479名参与者。我们计算了参与者的基线LS7指数，范围为0至7分，以便根据他们对这些LS7健康指标的遵守情况进行分类。使用多变量Cox回归模型来估计风险比（HR）及其95%置信区间（95%CI）。在中位随访4.8年后，我们确定了250例AF新发病例。在对潜在混杂因素进行调整后，遵守LS7指数与AF发病率无关（最高与最低LS7类别相比，调整后的HR为0.90[95%CI：0.56 - 1.45]）。体重指数<25kg/m²是唯一一项与较低AF风险单独相关的健康指标（HR为0.36[95%CI：0.16 - 0.78]）。
在心血管风险较高的西班牙人群中，遵守美国心脏协会的LS7指标与AF发病风险无关。
