P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity. The aim of this investigation was to evaluate the effect of percutaneous chronic total occlusion (CTO) revascularization on the parameters of P wave duration and PWD on ECG in cases before and after procedure at 12 months. We analyzed 90 consecutive CTO cases who were on sinus rhythm and underwent percutaneous coronary intervention (PCI). P-wave maximum (P) and P-wave minimum (P), P-wave time, and PWD were determined before and twelve months after the CTO intervention. The study population was categorized into two groups as successful and unsuccessful CTO PCI groups. The CTO PCI was successful in 71% of cases (n=64) and it was unsuccessful in 29% of cases (n=26). Both groups, except for age and hypertension, were similar in terms of demographic and clinical aspects. CRP levels were significantly elevated in the unsuccessful CTO PCI group. Pre-PCI ECG parameters showed no significant difference. Irrespective of the target vessel revascularization, we observed that PWD and P values were significantly lower in the 12 months follow-up. In all Rentrop classes, PWD values were significantly decreased at 12 months follow-up in comparison to the pre-CTO PCI values. This study has determined that PWD and P, which are both risk factors for atrial arrhythmias, are significantly reduced within 12 months after successful CTO PCI regardless of the target vessel.
从标准12导联心电图（ECG）获得的P波离散度（PWD）被认为可反映心房电活动的均匀性。本研究的目的是评估经皮慢性完全闭塞（CTO）血管重建术对12个月手术前后病例心电图上P波时限和PWD参数的影响。我们分析了90例连续的处于窦性心律且接受经皮冠状动脉介入治疗（PCI）的CTO病例。在CTO干预前和干预后12个月测定P波最大值（P）、P波最小值（P）、P波时限和PWD。研究人群分为成功和不成功CTO PCI两组。CTO PCI在71%的病例（n = 64）中成功，在29%的病例（n = 26）中不成功。除年龄和高血压外，两组在人口统计学和临床方面相似。不成功CTO PCI组的CRP水平显著升高。PCI前的心电图参数无显著差异。无论目标血管再血管化情况如何，我们观察到在12个月随访时PWD和P值显著降低。在所有Rentrop分级中，与CTO PCI前的值相比，12个月随访时PWD值显著降低。本研究确定，作为房性心律失常危险因素的PWD和P，在成功的CTO PCI术后12个月内无论目标血管如何均显著降低。
