摘要
脂蛋白(a) [Lp(a)]与心肌纤维化和内皮功能障碍有关，这是舒张功能障碍（DD）的潜在机制。本研究评估了保留射血分数（EF）患者Lp(a)升高（≥50 mg/dL）与DD之间的关系。目的：我们分析了1492名成年人（中位年龄59岁）的Lp(a)测量和超声心动图（1997-2024）。方法：舒张功能障碍需要≥3个异常回声参数，根据最近的指南。对潜在混杂因素进行logistic回归调整。结果：77例（5.1%）患者患有DD， Lp(a)≥50 mg/dL与DD无关[调整比值比（aOR）： 0.89, 95%可信区间（CI）： 0.49-1.54]。然而，年龄（aOR:1.03, p = 0.026）、高血压（aOR: 1.83, p = 0.042）、糖尿病（aOR: 2.43, p =0.002）和心血管（CV）疾病（aOR: 1.90, p = 0.043）与dd相关，而他汀类药物治疗与降低风险相关（aOR: 0.51, p = 0.016）。结论：在保留EF的情况下，Lp(a)与DD无关，强调传统心血管风险的管理。
Association Between Elevated Lipoprotein(a) and Diastolic Dysfunction: A Retrospective Cohort Study.
Introduction: Lipoprotein(a) [Lp(a)] has been linked to myocardial fibrosis and endothelial dysfunction, proposed mechanisms for diastolic dysfunction (DD). This study assessed the association between elevated Lp(a) (≥ 50 mg/dL) and DD in patients with preserved ejection fraction (EF).
Aim: We analyzed 1492 adults (median age59) with an Lp(a) measurement and echocardiogram (1997-2024).
Methods: Diastolicdysfunction required ≥ 3 abnormal echo parameters, as per recent guidelines. Logisticregression adjusting for potential confounders was performed.
Results: Seventy-sevenpatients (5.1%) had DD. Lp(a) ≥ 50 mg/dL was not associated with DD [adjusted oddsratio (aOR): 0.89, 95% confidence interval (CI): 0.49-1.54]. However, age (aOR:1.03, p = 0.026), hypertension (aOR: 1.83, p = 0.042), diabetes mellitus (aOR: 2.43, p =0.002), and cardiovascular (CV) diseases (aOR: 1.90, p = 0.043) were associated withDD, while statin therapy was associated with reduced risk (aOR: 0.51, p = 0.016).
Conclusions: In the setting of preserved EF, Lp(a) was not associated with DD,emphasizing management of traditional CV risks.
