In vivo knee rotational stability 2 years after the ACL reconstruction using a quadriceps tendon graft with bone block and bone-patellar tendon-bone graft.

INTRODUCTION: The aim of this prospective randomised study was to evaluate clinical results and rotational stability at least 2 years after single-bundle anatomic anterior cruciate ligament reconstruction using a quadriceps tendon graft with bone block (BT) and bone-patellar tendon-bone graft (BTB). MATERIALS AND METHODS: In both groups (BT and BTB), 40 patients selected prospectively at random were evaluated. The mean follow-up after the surgery was 28 months (range 24-33 months). A navigation system was used to measure rotational stability of the knee joint. Cincinnati, Lysholm, and IKDC scores and visual analog score (VAS) were used to evaluate clinical results and the non-parametric Wilcoxon test was used for the statistical analysis. RESULTS: After the BT reconstruction, the mean internal rotation of the tibia (IR) was 9.5°. In the contralateral healthy knee joint, IR was 8.6° at average. After the BTB reconstruction, the mean IR was 9.9°. In the contralateral healthy knee joint, IR was 8.7° at average. We did not find any statistically significant difference in IR stability between BT and BTB reconstruction. In terms of clinical results, regarding the VAS, patients perceive significantly more pain after the BTB reconstruction (p < 0.05). Kneeling was reported more difficult and painful after BTB reconstruction. CONCLUSIONS: The BT reconstruction of the ACL provides similar clinical results, less pain, better flexion and the same rotational stability of the knee in comparison with the BTB reconstruction.

Dysglycemia and Abnormal Adiposity Drivers of Cardiometabolic-Based Chronic Disease in the Czech Population: Biological, Behavioral, and Cultural/Social Determinants of Health.

In contrast to the decreasing burden related to cardiovascular disease (CVD), the burden related to dysglycemia and adiposity complications is increasing in Czechia, and local drivers must be identified. A comprehensive literature review was performed to evaluate biological, behavioral, and environmental drivers of dysglycemia and abnormal adiposity in Czechia. Additionally, the structure of the Czech healthcare system was described. The prevalence of obesity in men and diabetes in both sexes has been increasing over the past 30 years. Possible reasons include the Eastern European eating pattern, high prevalence of physical inactivity and health illiteracy, education, and income-related health inequalities. Despite the advanced healthcare system based on the compulsory insurance model with free-for-service healthcare and a wide range of health-promoting initiatives, more effective strategies to tackle the adiposity/dysglycemia are needed. In conclusion, the disease burden related to dysglycemia and adiposity in Czechia remains high but is not translated into greater CVD. This discordant relationship likely depends more on other factors, such as improvements in dyslipidemia and hypertension control. A reconceptualization of abnormal adiposity and dysglycemia into a more actionable cardiometabolic-based chronic disease model is needed to improve the approach to these conditions. This review can serve as a platform to investigate causal mechanisms and secure effective management of cardiometabolic-based chronic disease.

Cardiac rehabilitation and its essential role in the secondary prevention of cardiovascular diseases.

Cardiovascular diseases are the most common causes of mortality worldwide. They are frequently the reasons for patient hospitalization, their incapability for work, and disability. These diseases represent a significant socio-economic burden affecting the medical system as well as patients and their families. It has been demonstrated that the etiopathogenesis of cardiovascular diseases is significantly affected by lifestyle, and so modification of the latter is an essential component of both primary and secondary prevention. Cardiac rehabilitation (CR) represents an efficient secondary prevention model that is especially based on the positive effect of regular physical activity. This review presents an overview of basic information on CR with a focus on current trends, such as the issue of the various training modalities, utilization, and barriers to it or the use of telemedicine technologies. Appropriate attention should be devoted to these domains, as CR continues evolving as an effective and readily available intervention in the future.

Arterial Stiffness and Cardiometabolic-Based Chronic Disease: The Kardiovize Study.

OBJECTIVE: Arterial stiffness (ArSt) describes a loss of arterial wall elasticity and is an independent predictor of cardiovascular events. A cardiometabolic-based chronic disease model integrates concepts of adiposity-based chronic disease (ABCD), dysglycemia-based chronic disease (DBCD), and cardiovascular disease. We assessed if ABCD and DBCD models detect more people with high ArSt compared with traditional adiposity and dysglycemia classifiers using the cardio-ankle vascular index (CAVI). METHODS: We evaluated 2070 subjects aged 25 to 64 years from a random population-based sample. Those with type 1 diabetes were excluded. ABCD and DBCD were defined, and ArSt risk was stratified based on the American Association of Clinical Endocrinologists criteria. RESULTS: The highest prevalence of a high CAVI was in stage 2 ABCD (18.5%) and stage 4 DBCD (31.8%), and the lowest prevalence was in stage 0 ABCD (2.2%). In univariate analysis, stage 2 ABCD and all DBCD stages increased the risk of having a high CAVI compared with traditional classifiers. After adjusting for age and gender, only an inverse association between obesity (body mass index ≥30 kg/m2) and CAVI remained significant. Nevertheless, body mass index was responsible for only 0.3% of CAVI variability. CONCLUSION: The ABCD and DBCD models showed better performance than traditional classifiers to detect subjects with ArSt; however, the variables were not independently associated with age and gender, which might be explained by the complexity and multifactoriality of the relationship of CAVI with the ABCD and DBCD models, mediated by insulin resistance.

Associations between high triglycerides and arterial stiffness in a population-based sample: Kardiovize Brno 2030 study.

BACKGROUND: The term arterial stiffness (ArSt) describes structural changes in arterial wall related to the loss of elasticity and is known as an independent predictor of cardiovascular diseases (CVD). The evidence relating to ArSt and triglycerides (TG) shows contradictory results. This paper means to survey the association between high TG and ArSt, utilizing the cardio-ankle vascular index (CAVI). METHODS: Subjects aged between 25 and 64 years from a random population-based sample were evaluated between 2013 and 2016. Data from questionnaires, blood pressure, anthropometric measures, and blood samples were collected and analyzed. CAVI was measured using VaSera VS-1500 N devise. Subjects with a history of CVD or chronic renal disease were excluded. RESULTS: One thousand nine hundred thirty-four participants, 44.7% of males, were included. The median age was 48 (Interquartile Range [IQR] 19) years, TG levels were 1.05 (0.793) mmol/L, and CAVI 7.24 (1.43) points. Prevalence of high CAVI was 10.0% (14.5% in males and 6.4% in females; P <  0.001) and prevalence of hypertriglyceridemia was 20.2% (29.2% in males and 13% in females, P <  0.001). The correlation between TG and CAVI was 0.136 (P <  0.001). High CAVI values were more prevalent among participants with metabolic syndrome (MetS), high blood pressure, dysglycemia, abdominal obesity, high LDL-cholesterol (LDL-c), and high total cholesterol. Using binary regression analysis, high TG were associated with high CAVI, even after adjustment for other MetS components, age, gender, smoking status, LDL-c, and statin treatment (ß = 0.474, OR = 1.607, 95% CI = 1.063-2.429, P = 0.024). CONCLUSION: TG levels were correlated with ArSt, measured as CAVI. High TG was associated with high CAVI independent of multiple cardiometabolic risk factors. Awareness of the risks and targeted treatment of hypertriglyceridemia could further benefit in reducing the prevalence of CVD and events.

[The importance of evaluating the effectiveness of the ventilation VE/VCO2 slope in patients with heart failure]. / Význam hodnocení ventilacní efektivity VE/VCO2 slope u pacientu se srdecním selháním.

Chronic Heart Failure (CHF) is accompanied by a whole range of symptoms, which significantly decrease the quality of life; these typically concern dyspnoea, fatigue and exercise intolerance. The objectification of the patients condition but must have an effective means of evaluation. One such resource is cardiopolmonary exercise (CPX) testing with it is functional parameters. CPX test with its functional parameters is one of such means. VO2peak is undoubtebly the parameter, which was used the most often in the past 25 years, however, it has many limitations. It is reason, why the evaluation of ventilation effectiveness using the VE/VCO2 slope is becoming more and more the centre of Czech and foreign interest of cardiologists abroad. Foreign studies have unambiguously proven that because of the absence of the fundamental limitations, such as in case of VO2peak, the VE/VCO2 slope is a stronger predictor of the amount of hospitalizations and of mortality in the population of patients suffering from CHF. This short overview intends to inform of the significant merit of this parameter. That is the reason why the VE/VCO2 should be classified as a standard criterion in indication of heart transplantations, but also in evaluation of seriousness and prognosis in population of patient suffering from HF.Key words: heart failure - mortality - prognosis - ventilation efficiency - VE/VCO2 slope.

PREVENTIVE TRAINING PROGRAMME FOR PATIENTS AFTER ACUTE CORONARY EVENT-- CORRELATION BETWEEN SELECTED PARAMETERS AND AGE GROUPS.

AIM: Interventional cardiovascular training programmes provide a prescription of optimal form and safe intensity. They are part of the second phase of cardiovascular rehabilitation which is a key point in the whole tertiary-preventive care for patients with coronary artery disease. The patients are hemodynamically adapted to a normal physical load, their aerobic capacity is gradually increased, and they learn principles of regular aerobic-resistance exercise. The aim of this study is to assess the impact of modified aerobic-resistance exercise on cardiorespiratory indicators in patients after acute coronary event, and evaluate the differences between monitored parameters in different age groups. METHODS: The study was conducted on a group of 106 patients (85% of men) of an average age of 60.4 ± 10.9 years, with left ventricular ejec- tion fraction of 57.4 ± 7.2%. All subjects went through an acute coronary event. The time elapsed between the occurence of a coronary event and the beginning of the training programme was 35 ± 8 days. In patients after coronary artery bypass grafting, the time passed was 50 ± 16 days on average. All patients received a two-month aerobic-resistance training with a frequency of three times a week. The length of a training unit was set to 100 minutes (out of which 60 minutes were allocated to individual aerobic training). RESULTS: A significant negative correlation between age and average values of monitored parameters was observed. Even though the values of all parameters are decreasing with increasing age, a shift towards higher values in all parameters occurred after completing the training programme. The study reveals that there are interindividual differences between the parameter values. Asignificant difference in individual parameters was found between different age groups. The result of the study shows that a given parameter could characterize each age group. Completing the interventional training programme also led to a significant increase of exercise tolerance (1.8 ± 0.3 vs. 2.0 ± 0.4 W/kg; p < 0.001) and of peak oxygen consumption (22.8 ± 4.5 vs. 25.9 ± 5.5 ml/kg/min, p < 0.001). CONCLUSION: Interindividual differences between the parameter values have been identified. This could be helpful in methodological conception of preventive training programmes for patients suffering from cardiovascular disease. The mutual connection between the parameter values and age groups does not relate only to a safer training intensity determination, but also to a more precisely targeted application of different training modalities in order to achieve an optimal final training effect.
