In patients with coronary artery disease (CAD), fragmented QRS (fQRS) is a practical marker of myocardial ischemia evaluated on electrocardiography (ECG).The current study investigated the connection between FQRS and erectile dysfunction (ED), which is commonly accepted as an early sign and independent predictor of CAD. The study consisted of a 190 ED patients; 47 of them having severe, 44 moderate, 49 mild-to-moderate, and 50 mild ED, and a control group of 51 otherwise healthy adult men. None of the participants had a history of cardiac disease. There was a significant difference among the groups in terms of fQRS; severe, moderate, and mild-to-moderate ED groups had significantly higher rates of fQRS presence on ECG (27.5%, 23.5%, and 22.5%, respectively) in comparison with those of mild ED and the control groups (13.7% and 12.7%, respectively) (p < 0.001). In patients presenting with ED complaints, a fQRS finding on a simple ECG recording may serve as a first sign of the presence of CAD. As far as we know, the present study is the first in the literature assessing the possible relationship between ED and fQRS. On the ECG, the existence of fQRS was considered to be connected with ED; thus, including this basic parameter into the clinical decisions for ED patients may initiate an extensive diagnostic approach for their underlying cardiovascular diseases.

勃起功能障碍与动脉粥样硬化之间关系的新证据：零碎QRS？

在冠心病（CAD）患者中，QRS（fQRS）片段化是通过心电图（ECG）评估的心肌缺血的实用标志物。本研究调查了FQRS与勃起功能障碍（ED）之间的联系，这通常被认为是CAD的早期征兆和独立预测因子。该研究由190名ED患者组成。其中47例患有重度，44例中度，49例轻至中度和50例轻度ED，对照组为51例其他健康的成年男性。没有参与者有心脏病史。在fQRS方面，各组之间存在显着差异。重度，中度和轻度至中度ED组与轻度ED组和对照组（13.7％和12.7）相比，心电图上的fQRS存在率显着更高（分别为27.5％，23.5％和22.5％）。 ％，分别）（p <0.001）。对于有ED投诉的患者，在简单的ECG记录中发现fQRS可能是CAD出现的第一个迹象。据我们所知，本研究是评估ED和fQRS之间可能关系的文献中的第一篇。在ECG上，fQRS的存在被认为与ED有关；因此，将这一基本参数纳入ED患者的临床决策可能会为他们潜在的心血管疾病启动广泛的诊断方法。fQRS的存在被认为与ED有关；因此，将这一基本参数纳入ED患者的临床决策可能会为他们潜在的心血管疾病启动广泛的诊断方法。fQRS的存在被认为与ED有关；因此，将这一基本参数纳入ED患者的临床决策可能会为他们潜在的心血管疾病启动广泛的诊断方法。
