To examine whether baseline pulse pressure (PP), a marker of arterial stiffness, is associated with subsequent development of atrial fibrillation (AF) in type 2 diabetes.
A total of 350 type 2 diabetic patients, who were free from AF at baseline, were followed for 10 years. A standard electrocardiogram was performed annually and a diagnosis of incident AF was confirmed in affected participants by a single cardiologist.
During the follow-up, 32 patients (9.1% of total) developed incident AF. After adjustments for age, sex, BMI, diabetes duration, presence of left ventricular hypertrophy, hypertension treatment, kidney dysfunction, and pre-existing history of coronary heart disease, heart failure, and mild valvular disease, baseline PP was associated with an increased incidence of AF (adjusted odds ratio 1.76 for each SD increment [95% CI 1.1-2.8]; P < 0.01).
Our findings suggest that increased PP independently predicts incident AF in patients with type 2 diabetes.
探讨基线脉压(PP)作为动脉僵硬度的标志物,与 2 型糖尿病患者心房颤动(AF)的发生是否相关。
共纳入 350 例基线时无 AF 的 2 型糖尿病患者,随访 10 年。每年进行标准心电图检查,由一名心脏病专家对确诊的新发 AF 患者进行确诊。
在随访期间,32 例患者(占总患者的 9.1%)发生了新发 AF。调整年龄、性别、BMI、糖尿病病程、左心室肥厚、高血压治疗、肾功能障碍以及既往冠心病、心力衰竭和轻度瓣膜病的病史后,基线 PP 与 AF 发生率的增加相关(每增加 1 个 SD 的调整比值比为 1.76[95%CI 1.1-2.8];P<0.01)。
我们的研究结果表明,基线 PP 升高独立预测 2 型糖尿病患者新发 AF。
