: Dietary recommendations are an essential part of guidelines for the best management of chronic cardiovascular diseases. The present study aimed to validate the Greek version of Cardiovascular Diet Questionnaire 2 (CDQ-2) and to assess the dietary habits among cardiovascular patients. : A single-center cross-sectional observational study was conducted. The study population was cardiovascular patients that were users of a private primary healthcare clinic. The data were collected between December 2024 and January 2025. The questionnaire was translated from French, back-translated, and reviewed by a committee of experts. The MEDAS was used as a gold standard. The psychometric measurements that were performed included reliability coefficients and Explanatory Factor Analysis (EFA). : The total sample comprised 90 individuals. The Cronbach's α was 0.97. A bivariate Pearson's correlation established that there was a strong, statistically significant linear relationship between the CDQ-2 and MEDAS scores, with r(90) = 0.962 and < 0.001. Cardiovascular patients seemed to have suboptimal dietary patterns, as indicated by the relatively low mean CDQ-2 score of 2.9 (SD = 17.2), along with a mean MEDAS score of 8 (SD = 5.2), where younger individuals ( < 0.001), males ( = 0.042), single/divorced/widowed individuals ( < 0.001), individuals with lower physical activity ( = 0.001), and active smokers ( = 0.022) demonstrated significantly poorer adherence to the optimal cardiovascular dietary status. : The survey indicated that CDQ-2 was a valid and reliable scale to use in cardiovascular patients in Greece. Also, the patients were characterized by suboptimal dietary habits, indicating the need for personalized interventions to improve their dietary habits.
饮食建议是慢性心血管疾病最佳管理指南的重要组成部分。本研究旨在验证心血管饮食问卷2（CDQ - 2）的希腊语版本，并评估心血管疾病患者的饮食习惯。：开展了一项单中心横断面观察性研究。研究人群为一家私立初级医疗诊所的心血管疾病患者。数据收集于2024年12月至2025年1月之间。问卷从法语翻译而来，进行了回译，并由一个专家委员会进行审核。MEDAS被用作金标准。所进行的心理测量包括信度系数和解释性因子分析（EFA）。：总样本包括90名个体。克朗巴哈α系数为0.97。双变量皮尔逊相关性分析表明，CDQ - 2与MEDAS得分之间存在强的、具有统计学显著性的线性关系，r(90) = 0.962，P < 0.001。心血管疾病患者的饮食习惯似乎不太理想，CDQ - 2平均得分相对较低，为2.9（标准差 = 17.2），同时MEDAS平均得分为8（标准差 = 5.2），其中较年轻个体（P < 0.001）、男性（P = 0.042）、单身/离异/丧偶个体（P < 0.001）、身体活动较少的个体（P = 0.001）以及当前吸烟者（P = 0.022）对最佳心血管饮食状况的依从性明显较差。：调查表明，CDQ - 2是用于希腊心血管疾病患者的有效且可靠的量表。此外，患者的饮食习惯不太理想，这表明需要进行个性化干预以改善他们的饮食习惯。
