Usefulness of physical function sub-item of SF-36 survey to predict exercise intolerance in patients with heart failure

Protein and Exercise to Reverse Frailty in Older Men and Women Undergoing Transcatheter Aortic Valve Replacement: Design of the PERFORM-TAVR Trial

Despite the high procedural success of transcatheter aortic valve replacement (TAVR), 2 out of 5 older adults report poor physical performance and health-related quality of life (HRQOL) in the ensuing months, particularly those with frailty. There has yet to be a trial examining the synergistic effects of exercise and protein supplementation to counteract frailty and improve patient-centred outcomes following TAVR. The PERFORM-TAVR trial is a multicentre parallel-group randomised clinical trial that is enrolling 200 frail older adults ≥ 70 years of age undergoing TAVR. Patients will be randomly allocated to 1 of 2 treatment groups: standard-of-care lifestyle education (control group) or protein-rich oral nutritional supplement for 4 weeks before TAVR with the addition of home-based supervised exercise sessions for 12 weeks after TAVR (intervention group). The primary outcome will be physical performance as measured by a blinded observer using the Short Physical Performance Battery at 3 months. Secondary outcomes at 3, 6, and 12 months will include HRQOL, as measured by the Short-Form 36 Physical and Mental Component summary scores, and a composite safety end point. The PERFORM-TAVR trial is testing a novel frailty intervention in older adults undergoing TAVR to optimise recovery and downstream HRQOL. This represents a potential paradigm shift that highlights the value of assessing and treating patients' frailty in parallel with their underlying heart valve disease.

Health-related quality of life in Welsh adults: psychometric properties of the SF-36v2 and normative data

OBJECTIVES

The use of normative data has become well-accepted and a common strategy to interpret individual's health outcome scores, which can help in making decisions. The objectives of this study were to obtain population normative data for the domains and component summaries of the 36-item SF-36® Health Survey (SF-36), and to evaluate its reliability and construct validity.

METHODS

This study was conducted using population-based data from the Welsh Health Survey (WHS; 2011-2015). This study used version 2 of the SF-36 (SF-36v2® Health Survey). The descriptive statistics and normative data for the eight domains and two summaries, physical component summary (PCS) and mental component summary (MCS), were calculated. Reliability assessment used internal consistency methods and construct validity assessment used known group comparisons and item-scale correlations.

STUDY DESIGN AND SAMPLE

We performed a secondary analyses of data from the Welsh Health Survey (WHS).

RESULTS

This study included 74,578 participants aged 16 years or older (53.6% were women). Participants aged 16-24 years scored higher on SF-36 scale than older groups on all domains. The SF-36 profiles by age group demonstrated lower scores for older age groups, with the most pronounced differences shown on the physical-related scales. Across the age groups, men had higher PCS and MCS scores than women. All SF-36 domains and PCS and MCS achieved a good to excellent internal consistency reliability exceeding 0.7. The scales demonstrated construct validity by showing associations with a range of factors known to be related to health.

CONCLUSIONS

This study provides SF-36 normative data for Wales based on a representative data and confirms the construct validity and reliability of the SF-36.

Association of the quality of life parameters with the indicators of chronic heart failure severity in patients with rheumatoid arthritis

Background: The quality of life of patients is one of determining factors in assessing the effectiveness of treatment and prognosis. A search for possible associations of the quality of life parameters with basic clinical indicators provides a possibility of a more detailed and comprehensive assessment of the patients condition, correction of therapy and an improvement in the prognosis. Aim: To carry out a comparative analysis of the quality of life parameters in patients with chronic heart failure (CHF) with preserved and moderately reduced left ventricular ejection fraction against the background of rheumatoid arthritis (RA) and without RA, as well as to identify possible associations of the quality of life indicators with the parameters of the CHF course. Methods: 134 CHF patients with an RA diagnosis were examined, as well as 122 CHF patients without RA. The functional class of CHF in patients participated in the study was I -II by NYHA. The diagnosis of RA was made on the basis of radiological and serological studies. The radiological stage of RA in patients included in the study was I -III, according to Steinbrocker. Methotrexate was the basic anti-inflammatory drug for the RA treatment. A comparative analysis of the CHF symptoms, morphofunctional parameters and their possible association with the quality of life indicators in patients with and without RA was performed. The processing was carried out using the Statistica 10.0 program. Results: In the group of patients with CHF and RA, in addition to the statistically significant differences in the standard clinical laboratory parameters, statistically significant differences were also revealed in the severity of pain syndrome, deterioration of role, physical and emotional functioning as compared to the CHF patients without RA. Besides, in the CHF/RA group, statistically significant associations were revealed between the severity of pain syndrome and the level of the left ventricular ejection fraction and left ventricular mass index. Conclusion: The severity of pain syndrome caused by RA in patients with CHF can negatively affect some morphological and functional parameters of the myocardium, which must be taken into account when managing this group of patients.
