BACKGROUND Our aim is to evaluate the relationship between inspiratory muscle strength and venous refilling time, disease severity, and functional capacity in patients with chronic venous insufficiency (CVI). METHODS Sixty-one patients (49 female, aged 20-65 ) were enrolled in the study. The demographic characteristics of the patients were questioned. All patients were assessed with maximum inspiratory and expiratory pressure (MIP/MEP) for inspiratory and expiratory muscle strength, photoplethysmography for venous refilling time (VRT), venous clinical severity score (VCSS) for disease severity, and 6-min walk test (6-MWT) for functional capacity. RESULTS The mean age of the patients was 49.48 ± 13.19 years, and the mean duration of disease was 9.18 ± 6.57 years. There was statistically significant positive association between MIP and VRT(r: 0.331, p: 0.009), 6-MWT (r: 0.616, p < 0.001) values, and there was negative association between MIP and VCSS(r: -0.439 p < 0.001) scores. CONCLUSION Evaluation of inspiratory muscle strength and elimination of its deficiency, providing interventions to approach normative values have the potential to contribute positively to the treatment of the patient.

慢性静脉功能不全患者吸气肌力量、静脉再充盈时间、疾病严重程度和功能能力之间的关系。

背景我们的目的是评估慢性静脉功能不全（CVI）患者的吸气肌力量与静脉再充盈时间、疾病严重程度和功能能力之间的关系。方法 61 名患者（49 名女性，年龄 20-65 岁）纳入研究。患者的人口统计学特征受到质疑。所有患者均通过最大吸气和呼气压力 (MIP/MEP) 评估吸气和呼气肌力、光电体积描记法评估静脉再充盈时间 (VRT)、静脉临床严重程度评分 (VCSS) 评估疾病严重程度，以及 6 分钟步行测试（6 -MWT）功能能力。结果患者平均年龄为49.48±13.19岁，平均病程为9.18±6.57年。MIP 与 VRT（r：0.331，p：0.009）、6-MWT（r：0.616，p < 0.001）值之间呈显着正相关，MIP 与 VCSS 之间呈负相关（r：-0.439 p < 0.001）分数。结论 评估吸气肌力量并消除其缺陷，提供接近正常值的干预措施，有可能对患者的治疗做出积极贡献。
