Evaluation of physical activity level and exercise capacity in patients with varicose veins and chronic venous insufficiency

Comparison of the effects of training in the standing and lying positions on the quality of life and clinical symptoms in women with mild varicose veins: A randomized controlled trial

BACKGROUND

Patients with varicose veins are prevented from prolonged standing. Considering that exercise can be implemented in different positions, the aim of the current study was to compare the effects of training at standing and lying positions on quality of life, and clinical symptoms in women with mild varicose veins.

METHODS

Twenty-five women with mild varicose veins aged 35-50 years were randomly assigned to three groups; exercise at standing position (n=10), exercise at lying position (n=8) and control (no treatment) group (n=7). Each exercise program involved 6 weeks of training. Quality of life, pain severity, ankle swelling, and lower leg and ankle circumferences were measured using the Aberdeen Varicose Vein Questionnaire, Visual Analog Scale (VAS), four-point pitting edema grading scale, and tape measure, respectively at baseline and at the end of the study. Data were analyzed using one-way analysis of variance (ANOVA) and the least significant difference (LSD) as post hoc test.

RESULTS

Following a 6-week exercise program, there was a significant improvement in the quality of life of the participants in both exercise groups, and a significant reduction in pain, ankle swelling, and lower leg and ankle circumferences compared to pre-training and control group (P <0.05). However, there was no significant difference between two exercise groups in terms of study variables (P >0.05).

CONCLUSIONS

The current study showed that exercise program comprising standing position exercises can significantly reduce the symptoms of mild varicose veins.

Physical activity levels in patients with chronic venous insufficiency

BACKGROUND

Increasing the levels of physical activity (PA) is widely recommended for people with chronic venous insufficiency (CVI). However, studies investigating the patterns of PA and adherence to PA guidelines using objective measures are lacking.

OBJECTIVE

The primary aim was to examine the patterns of PA and adherence to PA guidelines among patients with CVI. A secondary aim was to identify whether adherence to PA recommendations differed according to patients' sociodemographic and clinical characteristics.

METHODS

This cross-sectional study included 96 patients with CVI with Clinical-Etiology-Anatomy-Pathology (CEAP) C3 to C6 (69.1% women 59 ± 11 years; 51.5% C5-C6 on CEAP classification). Objective time spent in PA was measured by a triaxial accelerometer. To examine adherence to PA guidelines, patients were grouped as meeting (or) the recommendations if they had at least 150 min/week of moderate to vigorous PA. Sociodemographic and clinic characteristics were obtained by self-report. Binary logistic regression was employed to examine whether sociodemographic and clinical characteristics were associated with adherence to PA guidelines. T-tests were employed to compare PA levels at different intensities according to patients' age.

RESULTS

Patients spent an average of 311.4 ± 91.5 min/week, 42.1 ± 28.0 min/week, and 19.8 ± 17.8 min/week in low-light PA, high-light PA, and moderate-to-vigorous PA, respectively. The proportion of patients meeting PA recommendations was 36.2%, and older patients had lower odds (OR = 0.94; 95%CI: 0.89 to 0.99). Additional analysis reinforced that by showing lower time in high-light PA (51.2 ± 30.0 min/day vs. 31.9 ± 21.8 min/day; p = .001) and moderate-to-vigorous PA (24.3 ± 15.8 min/day vs. 14.8 ± 18.8 min/day; p = .012) among older patients than their peers younger.

CONCLUSION

Our findings showed that 36,2% of CVI patients met PA recommendations, with lower odds found among older patients. Public health interventions to enhance PA engagement among CVI patients should prioritize those who are older.

Vicious Circle With Venous Hypertension, Irregular Flow, Pathological Venous Wall Remodeling, and Valve Destruction in Chronic Venous Disease: A Review

Substantial advances occurred in phlebological practice in the last two decades. With the use of modern diagnostic equipment, the patients' venous hemodynamics can be examined in detail in everyday practice. Application of venous segments for arterial bypasses motivated studies on the effect of hemodynamic load on the venous wall. New animal models have been developed to study hemodynamic effects on the venous system. In vivo and in vitro studies revealed cellular phase transitions of venous endothelial, smooth muscle, and fibroblastic cells and changes in connective tissue composition, under hemodynamic load and at different locations of the chronically diseased venous system. This review is an attempt to integrate our knowledge from epidemiology, paleoanthropology and anthropology, clinical and experimental hemodynamic studies, histology, cell physiology, cell pathology, and molecular biology on the complex pathomechanism of this frequent disease. Our conclusion is that the disease is initiated by limited genetic adaptation of mankind not to bipedalism but to bipedalism in the unmoving standing or sitting position. In the course of the disease several pathologic vicious circles emerge, sustained venous hypertension inducing cellular phase transitions, chronic wall inflammation, apoptosis of cells, pathologic dilation, and valvular damage which, in turn, further aggravate the venous hypertension.

Brazilian guidelines on chronic venous disease of the Brazilian Society of Angiology and Vascular Surgery

The Brazilian Society of Angiology and Vascular Surgery has set up a committee to provide new evidence-based recommendations for patient care associated with chronic venous insufficiency. Topics were divided in five groups: 1. Classification, 2. Diagnosis, 3. Conservative or non-invasive treatment, 4. Invasive treatment and 5. Treatment of small vessels. This last series is closely related to the activities of Brazilian angiologists and vascular surgeons, who are heavily involved in the treatment of small superficial veins. These guidelines are intended to assist in clinical decision-making for attending physicians and health managers. The decision to follow a guideline recommendation should be made by the responsible physician on a case-by-case basis taking into account the patient's specific condition, as well as local resources, regulations, laws, and clinical practice recommendations.

THE EFFECTS OF INSPIRATORY MUSCLE TRAINING VERSUS CALF MUSCLE TRAINING ON QUALITY OF LIFE, PAIN, VENOUS FUNCTION AND ACTIVITY IN PATIENTS WITH CHRONIC VENOUS INSUFFICIENCY

OBJECTIVE

The aim of this study was to evaluate the effect of inspiratory muscle training(IMT) and calf muscle exercise training(ETC) in addition to compression therapy(CT) on quality of life, venous refilling time, disease severity, pain, edema, range of motion, muscle strength and functionality in patients with chronic venous insufficiency (CVI) compared to compression treatment alone.

METHODS

Thirty-two participants diagnosed with CVI were randomly divided into three groups. IMT in addition to compression therapy, Group 1, exercise training for the calf muscle in addition to compression therapy, Group 2, and compression therapy alone, Group 3. All the patients were assessed with the Chronic Venous Insufficiency Quality of Life Questionnaire-20, Nottingham Health Profile, photoplethysmography, venous clinical severity score, visual analog scale, intraoral pressure measurements, dynamometer, digital goniometer, 6-minute walk test and lower extremity functional scale.

RESULTS

After treatment, Group 2 improved more than groups 1 and 3 in terms of quality of life, venous refilling time, pain, edema, range of motion, muscle strength and functionality scores; Group 1 improved more than groups 2 and 3 in terms of disease severity, inspiratory and expiratory muscle strength values(p<0.05). Only physical mobility and right leg venous refilling time increased in group 3(p<0.05).

CONCLUSIONS

IMT and ETC improve venous function in both legs in patients with CVI while CT alone improves venous function only in the right leg of patients with CVI.
