Accumulating evidence indicates that degenerative valvular heart disease (VHD) and rheumatoid arthritis (RA) share overlapping risk factors and intersecting inflammatory processes; however, their interrelationship remains insufficiently explored. Among 492 745 UK Biobank participants without VHD at baseline, Cox proportional hazards models were conducted to assess the association between prevalent RA and new-onset degenerative VHD, with sequential adjustments for demographic factors, lifestyle variables, and comorbidities. The end points of degenerative VHD in this study included 8 subtypes: aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation, tricuspid stenosis, tricuspid regurgitation, pulmonary stenosis, and pulmonary regurgitation. Among participants with RA (n=6673), 359 cases of degenerative VHD were recorded over a median follow-up of 13.71 (interquartile range, 12.71-14.55) years, compared with 13 518 cases in those without RA (n=486 072) over a median follow-up of 13.78 (interquartile range, 12.96-14.51) years. After full adjustment, RA was significantly associated with a higher risk of 3 types of new-onset degenerative VHD: aortic stenosis (hazard ratio [HR], 1.64 [95% CI, 1.40-1.92]), aortic regurgitation (HR, 1.69 [95% CI, 1.34-2.13]), and mitral regurgitation (HR, 1.54 [95% CI, 1.32-1.81]), while no significant association was observed between RA and other degenerative VHD subtypes. Moreover, sex subgroup analyses revealed an interaction between sex and RA in the occurrence of aortic stenosis (P for interaction=0.02) and mitral regurgitation (P for interaction=0.04), indicating a higher risk in women. The presence of RA indicated an elevated risk of new-onset degenerative aortic stenosis, aortic regurgitation, and mitral regurgitation, which required further investigation and better disease management.

BackgroundInflammation is involved in the progression of degenerative valvular heart disease (DVHD). microRNA-222 (miR-222) contributes to inflammation-mediated vascular remodeling, but its involvement in DVHD in relation to atrial fibrillation (AF) is unknown. This study aimed to investigate the changes in miR-222, interleukin (IL)-6, high-sensitivity C-reactive protein (hs-CRP), and N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with DVHD complicated with AF.MethodsThis was a case control study of patients with DVHD who were hospitalized at the Geriatrics Department of the Affiliated Huai’an Hospital of Xuzhou Medical University between 01/2017 and 08/2018. The participants were grouped according to the presence of AF, and serum miR-222, IL-6, hs-CRP, and NT-proBNP levels were compared.ResultsThere were fifty-two participants (28 males) in the DVHD with AF group, aged 60–80 years (73.0 ± 5.9 years). Sixty participants (31 males) were included in the DVHD without AF group, aged 60–80 years (71.9 ± 6.92 years). There were no significant differences in age, sex, body mass index, fasting blood glucose, triglycerides, cholesterol, and blood pressure between the two groups. The serum levels of miRNA-222, IL-6, hs-CRP, and NT-proBNP in DVHD patients were significantly higher in those with AF compared with the non-AF group (all P < 0.05). Correlation analyses revealed that IL-6, hs-CRP, and NT-proBNP levels were positively correlated with miR-222 levels in all patients (IL-6: r = 0.507, P < 0.01; hs-CRP: r = 0.390, P < 0.01; NT-proBNP: r = 0.509, P < 0.01).ConclusionsSerum miR-222 was independently associated with AF in patients with DVHD.

The definition of non-valvular atrial fibrillation (NVAF) is controversial. We aimed to assess the impact of valvular heart disease on stroke prevention strategies in NVAF patients. The RAMSES study was a multicenter and cross-sectional study conducted on NVAF patients (ClinicalTrials.gov identifier NCT02344901). The study population was divided into patients with significant valvular disease (SVD) and non-significant valvular disease (NSVD), whether they had at least one moderate valvular disease or not. Patients with a mechanical prosthetic valve and mitral stenosis were excluded. Baseline characteristics and oral anticoagulant (OAC) therapies were compared. In 5987 patients with NVAF, there were 3929 (66%) NSVD and 2058 (34%) SVD patients. The predominant valvular disease was mitral regurgitation (58.1%), followed by aortic regurgitation (24.1%) and aortic stenosis (17.8%). Patients with SVD had higher CHA2DS2VASc [3.0 (2.0; 4.0) vs. 4.0 (2.0; 5.0), p < 0.001] and HAS-BLED [2.0 (1.0; 2.0) vs. 2.0 (1.0; 2.0), p = 0.004] scores compared to patients with NSVD. Overall, 2763 (71.2%) of NSVD and 1515 (73.8%) of SVD patients were on OAC therapy (p = 0.035). When the patients with SVD were analyzed separately, the mean CHA2DS2VASc and HAS-BLED scores were higher in patients with mitral regurgitation compared to patients with aortic regurgitation and aortic stenosis [4.0 (3.0; 5.0), 3.0 (2.0; 4.0), 3.0 (2.0; 4.0) p < 0.001 and 2.0 (1.0; 3.0), 1.0 (1.0; 2.0), 1.0 (0.0; 2.0) p < 0.001, respectively]. In patients with SVD, 65.7% of mitral regurgitation, 82.6% of aortic regurgitation and 88.0% of aortic stenosis patients were on OAC therapy. One out of three NVAF patients had at least one moderate valvular heart disease with the predominance of mitral regurgitation. Patients with SVD were at greater risk of stroke and bleeding compared to patients with NSVD. Although patients with mitral regurgitation should be given more aggressive anticoagulant therapy due to their higher risk of stroke, they are undertreated compared to patients with aortic valve diseases.

Degenerative valvular heart disease, the most common form of valve disease in the Western world, can lead to aortic stenosis (AS) or mitral regurgitation (MR). In current guidelines for the management of patients with degenerative valvular disease, surgical intervention is recommended at the onset of symptoms or in the presence of left ventricular systolic impairment. Whether surgery is appropriate for asymptomatic patients remains a controversial issue. We argue the case for early pre-emptive intervention in selected, asymptomatic individuals with AS or MR, drawing on contemporary perioperative data, predictors of disease progression, and studies of the natural history of degenerative valvular heart disease.

Background: Despite the increasing prevalence of degenerative valvular heart disease (VHD), recommended preventive interventions are notably lacking. The cardiovascular-kidney-metabolic (CKM) health approach advocates for multidisciplinary early-stage disease prevention. We aimed to explore sex differences in CKM risk factors associated with VHD. Methods: Using data from UK Biobank, participants without a history of VHD or heart failure at baseline were included. We assessed the sex differences in hazard ratios (HRs) and population-attributable risk (PAR) for incident aortic valve stenosis (AS), aortic valve regurgitation (AR), and mitral valve regurgitation (MR) associated with five CKM risk factors: hypertension, diabetes, obesity, high lipoprotein(a), and chronic kidney disease (CKD). Results: Among 463,496 participants (54.4% women), AS, AR, and MR cases were observed at incidence of 1.05 and 0.52, 0.37 and 0.22, 1.04 and 0.70 events per 1000 person-years for men and women, respectively. Hypertension consistently accounted for the largest attributable risk factor for incident VHD in both sexes, with PARs of 29.96% and 26.61% for AS, 23.51% and 16.02% for AR, and 17.56% and 13.09% for MR in women and men, respectively. Compared to men, obesity, CKD, and hypertension were associated with higher risks of AS, AR, and MR in women (women-to-men ratios of HRs: 1.11[1.09–1.36], 1.62[1.01–2.63], and 1.27[1.09–1.49], respectively). Conclusions: This study offers comprehensive insights into the profiles of CKM risk factors for degenerative VHD among middle-aged individuals. Tailoring the prioritization of risk factors based on gender has the potential to improve the precision and effectiveness of VHD prevention strategies.

BackgroundData on the prevalence of valvular heart disease in very old individuals are scarce and based mostly on in-hospital series. In addition, the potential detrimental effect of valvular heart disease on the activities of daily living is unknown. The present study evaluated the prevalence of significant valvular heart disease and the impact of valvular heart disease on the activities of daily living in community dwelling nonagenarians. Nested within the Leiden 85-plus study, a population based follow-up study of the oldest old, a sample of 81 nonagenarians was recruited.MethodsThe left ventricular (LV) dimensions, function and the presence and severity of heart valvular disease were evaluated by echocardiography. Significant valvular heart disease included any mitral or aortic stenosis severity, moderate or severe mitral regurgitation, moderate or severe aortic regurgitation and moderate or severe tricuspid regurgitation. Activities of daily living were assessed using the Groningen Activity Restriction Scale (GARS).ResultsLV cavity diameters (end-diastolic diameter 47 ± 8 mm, end-systolic diameter 30 ± 8 mm) and systolic LV function (LV ejection fraction 66 ± 13%) were within normal for the majority of the participants. Significant valvular disease was present in 57 (70%) individuals, with mitral regurgitation and aortic regurgitation as the most frequent valve diseases (49% and 28% respectively). The GARS score between individuals with and without significant valvular heart disease was similar (36.2 ± 9.2 vs. 34.4 ± 13.2, p = 0.5).ConclusionsNonagenarian, outpatient individuals have a high prevalence of significant valvular heart disease. However, no relation was observed between the presence of significant valvular heart disease and the ability to perform activities of daily living.

Aim The present study was aimed at investigating the prevalence, incidence, progression, and prognosis of degenerative valvular heart disease (DVHD) in permanent residents aged ≥65 years from Guangzhou, China. Methods This was a prospective study based on community population. Over a 3-year span, we conducted repeated questionnaires, blood tests, and echocardiographic and electrocardiogram examinations (2018) of a random sample of initially 3538 subjects. Results The prevalence of DVHD increased with age, average values being 30.6%, 49.2%, and 62.9% in 65-74, 75-84, and ≥85 years of age, respectively. The incidence rate was 1.7%/year. Aortic stenosis was the result of DVHD, and the mean transvalvular pressure gradient increased by 5.6 mmHg/year. The increase of mild aortic stenosis was lower than that of more severe disease, showing a nonlinear development of gradient, but with great individual variations. Mortality was significantly increased in the DVHD group (HR = 2.49). Risk factors for higher mortality included age (χ2 = 1.9, P < 0.05), renal insufficiency (χ2 = 12.5, P < 0.01), atrial fibrillation (χ2 = 12.2, P < 0.01), mitral regurgitation (χ2 = 1.8, P < 0.05), and tricuspid regurgitation (χ2 = 6.7, P < 0.05) in a DVHD population. Conclusions DVHD was highly prevalent among residents in southern China. With the progression of the disease, the mean transvalvular pressure gradient accelerated. DVHD was an independent predictor of death, and the mortality was higher in those with older age, renal insufficiency, atrial fibrillation, mitral regurgitation, and tricuspid regurgitation.

However, very little is known regarding levels of knowledge and attitudes amongst non-cardiology clinicians in managing VHD. Purpose To determine the knowledge and attitudes towards VHD management, pertaining specifically to referrals to cardiology services for consideration for intervention, amongst internal medicine clinicians in Malaysia. Methods We conducted a multi-centre survey study. A 20-item survey was distributed amongst internal medicine clinicians within three different institutions. Results A total of 75 responses was obtained (response rate of 35.7%). The mean age of responders was 36.6 years (S.D. 7.9). 57.3% were male. Respondents include medical officers (50.6%), internal medicine consultants (31.9%) and internal medicine specialist (i.e. pre-consultant) (17.5%). Majority had more than 10 years of experience working as medical doctors (46.7%). 69.3% admit to managing patients with VHD regularly (defined as at least one VHD patient per week). Respondents were comfortable using online resources, both formal (95.0%) and informal (75.0%) sources. A large proportion felt that they had ‘insufficient’ or ‘very insufficient’ knowledge and experience managing VHD patients on their own (28.0% and 8.0% respectively) and less than half felt that management of VHD patients within their institutions was ‘adequate’ or ‘very adequate’ (46.7% and 2.7% respectively). However, it is reassuring that most respondents felt comfortable discussing cases of VHD with their senior colleagues or their local cardiology services. Although many were felt to be over-zealous in wanting too frequent an echocardiography monitoring for cases of mild VHD (majority felt that the patient would require it every 1 year (25.3%) or 1-2 years (29.3%)), nevertheless attitudes in referrals to cardiology services for consult and intervention were felt appropriate (majority felt that cardiology consult would be indicated if valvular lesion was at least moderate in severity (56.0%), when there were changes to the heart function or structure (52.0%), when patients became symptomatic (45.3%) or when there were two or more valvular lesions simultaneously (45.3%). However, within a Malaysian context, there may be a need to shift attitudes towards referring much earlier, consistent with changes in recent international guidelines on managing VHD, as valvular surgery waiting times are extremely long. Conclusion The survey highlights the need for education amongst internal medicine clinician to tackle both the over-zealous attitude in monitoring patients with mild valvular disease on one extreme, and in improving early referrals for VHD indicated for intervention in the other.

Asthma has been associated with the development and progression of various cardiovascular diseases but its relationship with degenerative valvular heart disease (VHD) remains unclear. This study investigated the association between asthma and incident degenerative VHD, including aortic stenosis (AS), aortic regurgitation (AR), mitral regurgitation (MR) and pulmonary regurgitation (PR). We analysed 483 735 participants from the UK Biobank (median age 56.5 years; 45.2% male) who were free of VHD at baseline. Asthma status was self-reported at recruitment. Incident VHD was ascertained through hospital admission and mortality records using International Classification of Diseases, Tenth Revision codes. Cox proportional hazards models were used to estimate HRs and 95% CIs for each VHD subtype, adjusting for demographic, lifestyle and clinical covariates. Sensitivity analyses accounted for asthma medications, duration of asthma and competing risks. Over a median follow-up of 13.8 years, 5388 participants developed AS, 2650 AR, 6088 MR and 821 PR. Asthma was associated with increased risk of AS (HR 1.31; 95% CI 1.21 to 1.41), AR (HR 1.24; 95% CI 1.11 to 1.39), MR (HR 1.19; 95% CI 1.10 to 1.28) and PR (HR 1.34; 95% CI 1.10 to 1.62). The association with AR was attenuated after adjusting for asthma medications (HR 1.12; 95% CI 0.97 to 1.30). Results were robust across multiple sensitivity analyses, including adjustment for asthma duration and exclusion of participants with pre-existing cardiovascular disease. Asthma is independently associated with a modestly increased risk of several degenerative VHDs, particularly aortic and mitral valve diseases. These findings suggest a potential shared inflammatory pathway and highlight the need for heightened cardiovascular surveillance in individuals with asthma.
