Functional assessment of patients after total knee replacement

Introduction: In the society of the 21st century, osteoarthritis is considered one of the primary causes of the occurrence of pain and disability. Arthroplasty is the treatment of choice for advanced degenerative changes. The aim of the study was to carry out a functional assessment of patients at early stages of rehabilitation after total knee replacement

Mitral and aortic regurgitation following transcatheter aortic valve replacement

OBJECTIVE: To analyse the impact of postprocedural mitral regurgitation (MR), in an interaction with aortic regurgitation (AR), on mortality following transcatheter aortic valve implantation (TAVI). METHODS: To assess the interaction between MR and AR, we compared the survival rate of patients (i) without both significant MR and AR versus (ii) those with either significant MR or significant AR versus (iii) with significant MR and AR, all postprocedure. 381 participants of the Polish Transcatheter Aortic Valve Implantation Registry (166 males (43.6%) and 215 females (56.4%), age 78.8±7.4 years) were analysed. Follow-up was 94.1±96.5 days. RESULTS: Inhospital and midterm mortality were 6.6% and 10.2%, respectively. Significant MR and AR were present in 16% and 8.1% patients, including 3.1% patients with both significant MR and AR. Patients with significant versus insignificant AR differed with respect to mortality (log rank p=0.009). This difference was not apparent in a subgroup of patients without significant MR (log rank p=0.80). In a subgroup of patients without significant AR, there were no significant differences in mortality between individuals with versus without significant MR (log rank p=0.44). Significant MR and AR had a significant impact on mortality only when associated with each other (log rank p<0.0001). At multivariate Cox regression modelling concomitant significant MR and AR were independently associated with mortality (OR 3.2, 95% CI 1.54 to 5.71, p=0.002). CONCLUSIONS: Significant MR or AR postprocedure, when isolated, had no impact on survival. Combined MR and AR had a significant impact on a patient's prognosis

Sex-related differences in clinical outcomes and quality of life after transcatheter aortic valve implantation for severe aortic stenosis

Introduction: There are inconsistent data on the sex-related differences in clinical outcomes and quality of life (QoL) after transcatheter aortic valve implantation (TAVI). Aim: We sought to investigate sex-related differences in procedural, clinical and QoL outcomes of TAVI. Material and methods: A total of 101 consecutive patients undergoing TAVI were enrolled. Patients were stratified by gender. Baseline characteristics, procedural and long-term clinical outcomes as well as frailty and QoL indices (EQ-5D-3L questionnaire) were compared between women and men. Results: Women represented 60.4% of the study population. Periprocedural risk measured with the Logistic EuroSCORE and STS scale was similar for women and men. There were no differences in 30-day or 12-month all-cause mortality between groups (women vs. men: 9.8% vs. 12.5%; age-adjusted odds ratio (OR) (95% CI): 1.38 (0.39–4.94); 13.1% vs. 25.0%; age-adjusted OR (95% CI): 2.51 (0.87–7.25)). Men were at higher risk of new onset atrial fibrillation at follow-up (1.6% vs. 17.5%; age-adjusted OR (95% CI): 14.61 (1.68–127.37)). In multivariable Cox regression analysis, a history of stroke/transient ischemic attack (TIA) (hazard ratio (HR)) (95% CI): 3.93 (1.39–11.07) and blood transfusion (HR (95% CI): 2.84 (1.06–7.63)) were identified as independent factors affecting 12-month mortality. No differences in QoL parameters were noted. Conclusions: The TAVI can be considered as an effective and safe treatment in high-risk patients with severe aortic stenosis, regardless of gender

CHA2DS2-VASc and R2-CHA2DS2-VASc scores predict in-hospital and post-discharge outcome in patients with myocardial infarction

Introduction: The CHA2DS2-VASc and R2-CHA2DS2-VASc scores were initially designed to evaluate the risk of cerebrovascular events in patients with atrial fibrillation. However, these scales consist of parameters which are well known as general risk factors for cardiovascular events. Aim: To assess the role of the CHA2DS2-VASc and R2-CHA2DS2-VASc scores in predicting outcome of patients with myocardial infarction (MI). Material and methods: We enrolled 212 consecutive patients with both ST-elevation and non-ST-elevation MI referred for primary percutaneous coronary intervention (PCI). Patients were divided into two groups depending on the CHA2DS2-VASc score: ≤ 3 (low score) and > 3 points (high score). Results: The group with a CHA2DS2-VASc score > 3 points consisted of 93 (44%) patients. Follow-up was available in 200 (94.3%) patients with median duration of 10 (Q1: 6; Q3: 13) months. During the follow-up all-cause mortality was greater in patients from the high score group (21%) compared to patients with lower scores (8%) (p = 0.009). Recurrent MI was found in 4% of patients from the low score group and in 13% of patients from the high score group (p = 0.024). The combined endpoint of cardiovascular mortality, recurrent non-fatal MI and non-fatal stroke occurred in 13% of lower score patients and in 30% of patients with a score > 3 points (p = 0.002). In a Cox regression model both scores were predictors of all-cause mortality with a hazard ratio of 1.31 per 1 point increase for the CHA2DS2-VASc score (p = 0.004) and 1.36 for the R2-CHA2DS2-VASc score (p < 0.001). Conclusions: The CHA2DS2-VASc and R2-CHA2DS2-VASc scores predict in-hospital and post-discharge outcome in patients with acute MI undergoing primary PCI

The obesity paradox in patients undergoing transcatheter aortic valve implantation : is there any effect of body mass index on survival?

Background: Conflicting results have been presented regarding the influence of body mass index (BMI) on outcomes among patients undergoing transcatheter aortic valve implantation (TAVI). Aims: To investigate the impact of BMI on clinical outcomes after TAVI. Methods: A total of 148 consecutive patients were categorised using baseline BMI according to the World Health Organization criteria. Baseline patient characteristics, frailty, and procedural and clinical outcomes including 30-day and 12-month all-cause mortality were compared between the BMI categories. Patients were followed up for a median of 460.0 (182.0–1042.0) days. Results: Obesity was diagnosed in 37 (25.2%) patients, 73 (49.7%) patients were overweight, and 37 (25.2%) had normal weight. Prevalence of lower frailty as assessed by five-metre walk test was confirmed in obese patients as compared to other groups. A trend towards a lower rate of in-hospital bleeding complications (18 [48.6%] vs. 21 [28.8%] vs. 9 [24.3%] in normal-weight, overweight, and obese patients, respectively; p = 0.06) and less frequent blood transfusions (18 [48.6%] vs. 17 [23.3%) vs. 8 [21.6%]; p = 0.016) was observed in overweight and obese groups. The rate of grade 3 acute kidney injury was lowest in the overweight group (4 [10.8%] vs. 1 [1.4%] vs. 3 [8.1%]; p = 0.05). There was no difference between the groups in terms of 30-day all-cause mortality (p = 0.15). However, 12-month all-cause mortality was lowest in obese pa­tients (12 [32.4%] vs. 10 [13.7%] vs. 2 [5.4%]; p = 0.004). Increase in BMI was independently associated with lower all-cause mortality (hazard ratio [95% confidence interval] per 1 kg/m2 increase: 0.91 [0.845–0.98]; p = 0.018). Conclusions: Increased BMI was independently associated with survival benefit after TAVI

Changes in cognitive functions and quality of life in patients after transcatheter aortic valve implantation

Introduction: Transcatheter aortic valve implantation (TAVI) has emerged as a therapeutic option for patients with severe aortic stenosis (AS). However, an association between cognitive functions (CF) and health-related quality of life (HRQoL) in TAVI patients is still unclear. Aim: To assess the long-term changes in CF and HRQoL in elderly patients with AS after TAVI. Material and methods: A total of 259 patients who underwent cardiological and psychological TAVI qualification were enrolled and divided into the normal (n = 174) and impaired cognition group (n = 85). CF and HRQoL characteristics assessed at baseline and 13 months were compared between groups. The analysis of multiple linear regression was performed to identify the association between HRQoL and CF and to assess the influence of TAVI on HRQoL. Results: There was no difference in CF between baseline and follow-up. However, an improvement in attention functions and memory skills in the cognitively impaired group was noted at follow-up. In addition, HRQoL scores increased in both groups. An independent predictor associated with HRQoL was global CF (β = –213, p = 0.01), which explained 7% of CF variation. Improvements in all five dimensions of HRQoL, from 4.8% in self-care and up to 33.6% in pain/discomfort, were found. At follow-up, 60% of TAVI patients had improved health, 12% had worse health, 4% showed no change and 24% had a “mixed” change. Conclusions: TAVI is associated with positive changes in the functioning of elderly patients at long-term follow-up

Assessment of mitral regurgitation and mitral complex geometry in patients after transcatheter aortic valve implantation

Introduction: Mitral regurgitation (MR) of varying degrees and mechanisms is a common finding in patients with aortic stenosis with different improvement after transcatheter aortic valve implantation (TAVI). Aim: To evaluate the impact of TAVI on mitral complex geometry and the degree of MR. Material and methods: A total of 31 patients (29.0% males) with severe aortic stenosis and moderate or severe MR at the baseline who underwent TAVI were included in this study. Clinical and echocardiographic characteristics were determined at baseline and at 6 and 12 months. Results: After TAVI, decrease of MR vena contracta width (p = 0.00002, p = 0.00004), aorto-mural mitral annulus diameter (p = 0.00008, p = 0.02), increase of mitral annular plane systolic excursion (p = 0.0004, p = 0.0003), left ventricular stroke volume (p = 0.0003, p = 0.0004), ejection fraction (p = 0.0004, p = 0.01) and decrease of major dimension of left ventricle in three chamber view (p = 0.05, p = 0.002) were observed in patients at both time points. Additionally, we observed a decrease of distance between the head of the papillary muscles (p = 0.003) at 6 months and a decrease of left atrium volume index (p = 0.01) and systolic pulmonary artery pressure (p = 0.01) at 12 months. Conclusions: Patients with moderate or severe MR undergoing TAVI achieved significant improvement of mitral valve complex function resulting in the reduction of MR degree
