Abstract
The impact of aortic stenosis on platelet reactivity is unclear. Previous studies reported contradicting results. The reason for this is unknown. It is known that flow alterations enhance platelet reactivity. A steep left ventricular-aortic angle (LV-AO-angle) is associated with turbulent flow in the aorta ascendens. Therefore, in this study, we hypothesized that LV-AO-angle is associated with platelet reactivity in patients with severe aortic stenosis. We included 289 patients with severe aortic stenosis and performed cardiac computertomography to assess the LV-AO-angle. Platelet function was evaluated by light transmission aggregometry. Platelet reactivity was higher in patients with a steep LV-AO-angle (ADP: <160°: 66.99% ± 20.72% vs. ≥160°: 60.66% ± 19.85%, P = 0.009; collagen: <160°: 78.67% ± 13.19% vs. ≥160°: 73.85% ± 14.44%, P = 0.003). Using Spearman correlation, ADP and collagen-induced aggregation was associated with LV-AO-angle (ADP: r = -0.19, P = 0.0009, R2 = 0.022; collagen: r = -0.21, P = 0.0004, R2 = 0.027). Apart from platelet reactivity, body weight, history of myocardial infarction and other factors were associated with steep LV-AO-angle. However, multivariate cox-regression (including body weight, comorbidities, history of MI and cardiac surgery, kidney function and laboratory parameters) revealed that LV-AO angle was a robust predictor of ADP and collagen-induced platelet aggregation. Steep LV-AO-angle is associated with enhanced platelet reactivity in patients with aortic stenosis. This could be the reason of contradicting results regarding platelet function in patients with aortic stenosis in previous studies. In addition, enhanced platelet reactivity in steep LV-AO-angle aortic stenosis patients might be a promising target in pathogenesis of aortic stenosis.

Left ventricular asymmetric remodeling and subclinical left ventricular dysfunction in patients with calcific aortic valve stenosis - Results from a subanalysis of the PROGRESSA study. Int J Cardiol 2021; 332:148-156. [PMID: 33727121 DOI: 10.1016/j.ijcard.2021.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 01/09/2021] [Accepted: 03/08/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND LV asymmetric remodeling (LVAR) is a feature commonly found in AS patients and it is presumed to be mainly related to the severity of valve stenosis. The aim of this study was to determine the associated factors and impact on left ventricular (LV) systolic function of LVAR in patients with mild and moderate aortic valve stenosis (AS). METHODS Clinical, Doppler-echocardiographic and computed-tomographic data of 155 AS patients with preserved LV ejection fraction (≥50%) prospectively recruited in the PROGRESSA study (NCT01679431) were analyzed. LVAR was defined as a septal wall thickness ≥ 13 mm and a ratio of septal/posterior wall thickness > 1.5. LV global longitudinal strain (LV-GLS) was available in 129 patients. Plasma levels of N-terminal natriuretic B-type peptides (Nt-proBNP) were also measured. RESULTS Mean age was 63 ± 15 years (70% men). LVAR was present in 21% (n = 33) of patients. A series of nested multivariate analysis revealed that age was the only factor associated with LVAR (all p ≤ 0.03). Additionally, these patients had higher baseline Nt-proBNP ratio (median [25-75 percentiles]: 1.04 [0.66-2.41] vs. 0.65 [0.33-1.19], p = 0.02), and significantly reduced LV-GLS (17.9[16.6-19.5] vs. 19.3[17.4-20.7] |%|, p = 0.04). A 1:1 matched analysis showed a significant association of LVAR with reduced LV-GLS (17.9[16.6-19.5] vs. 19.8[18.1-20.7] |%|, p = 0.02) and elevated Nt-proBNP (134[86-348] vs. 83[50-179]pg/ml, p = 0.03). Multivariable analysis also revealed that LVAR remains significantly associated with reduced LV-GLS (p = 0.03) and elevated Nt-proBNP (p = 0.001). LVAR was significantly associated with increased risk of major adverse cardiac events and death (Hazard ratio [95% confidence interval]: 2.32[1.28-4.22], p = 0.006). CONCLUSIONS LVAR was found in ~20% of patients with mild or moderate AS and was not related to the degree of AS severity or concomitant comorbidities, but rather to older age. LVAR was significantly associated with reduced LV longitudinal systolic function, increased Nt-proBNP levels, and higher risk of major adverse events and death. These findings provide support for closer clinical and echocardiographic surveillance of patients harboring this adverse LV remodeling feature.

Natural progression of cardiac features and long-term effects of enzyme replacement therapy in Taiwanese patients with mucopolysaccharidosis II. Orphanet J Rare Dis 2021; 16:99. [PMID: 33622387 PMCID: PMC7903682 DOI: 10.1186/s13023-021-01743-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 02/11/2021] [Indexed: 11/29/2022] Open
Abstract
Background Cardiac abnormalities have been observed in patients with mucopolysaccharidosis type II (MPS II). The aim of this study was to investigate the cardiac features and natural progression of Taiwanese patients with MPS II, and evaluate the impact of enzyme replacement therapy (ERT) on cardiac structure and function. Methods The medical records and echocardiograms of 48 Taiwanese patients with MPS II (median age, 6.9 years; age range, 0.1–27.9 years) were reviewed. The relationships between age and each echocardiographic parameter were analyzed. Results The mean z-scores of left ventricular mass index (LVMI), interventricular septum diameter in diastole (IVSd), left ventricular posterior wall diameter in diastole (LVPWd), and aortic diameter were 1.10, 2.70, 0.95 and 1.91, respectively. Z scores > 2 were identified in 33%, 54%, 13%, and 46% for LVMI, IVSd, LVPWd, and aortic diameter, respectively. The most prevalent cardiac valve abnormality was mitral regurgitation (MR) (56%), followed by aortic regurgitation (AR) (33%). The severity of mitral stenosis (MS), MR, aortic stenosis (AS), AR, and the existence of valvular heart disease were all positively correlated with increasing age (p < 0.01). We also compared the echocardiographic parameters between two groups: (1) 12 patients who had up to 17 years of follow-up echocardiographic data without ERT, and (2) nine patients who had up to 12 years of follow-up data with ERT. The results showed that z-score changes of LVMI significantly improved in the patients who received ERT compared to those who did not receive ERT (0.05 versus 1.52, p < 0.05). However, the severity score changes of MS, MR, AS, and AR all showed gradual progression in both groups (p > 0.05). Conclusions High prevalence rates of valvular heart disease and cardiac hypertrophy were observed in the MPS II patients in this study. The existence and severity of cardiac hypertrophy and valvular heart disease in these patients worsened with increasing age, reinforcing the concept of the progressive nature of this disease. ERT for MPS II appeared to be effective in stabilizing or reducing the progression of cardiac hypertrophy, but it only had a limited effect on valvulopathy.

Abstract
OBJECTIVE In hypertension, indexes of midwall left ventricular (LV) function may identify patients at higher cardiovascular (CV) risk independent of normal LV ejection fraction (EF). We analyzed the association of baseline and new-onset LV midwall dysfunction with CV outcome in a large population of patients with asymptomatic aortic stenosis (AS). METHODS One thousand four hundred seventy-eight patients with asymptomatic AS and normal EF (≥50%) at baseline in the Simvastatin Ezetimibe in Aortic Stenosis (SEAS) study were followed for a median of 4.3 years. LV systolic function was assessed by biplane EF and midwall shortening (MWS, low if <14% in men/16% in women) at baseline and annual echocardiographic examinations. RESULTS One hundred twenty-three CV deaths and heart failure hospitalizations occurred during follow-up. In Cox analyses, adjusting for age, gender, body mass index, hypertension, EF, AS severity, LV hypertrophy and systemic arterial compliance, low baseline MWS predicted 61% higher risk of a major CV event and a twofold higher risk of death and heart failure hospitalization (P < .05). New-onset low MWS developed in 574 patients, particularly in elderly women with higher blood pressure and more severe AS (P < .05). In time-varying Cox analysis, new-onset low MWS was associated with a twofold higher risk of CV death and heart failure hospitalization, independent of changes over time in EF, AS severity, LV hypertrophy and systemic arterial compliance (P < .05). CONCLUSIONS Low MWS develops in a large proportion of patients with AS and normal EF during valve disease progression and is a marker of increased CV risk.

Abstract
BACKGROUND Mucopolysaccharidosis type III (MPS III), or Sanfilippo syndrome, is caused by a deficiency in one of the four enzymes involved in the lysosomal degradation of heparan sulfate. Cardiac abnormalities have been observed in patients with all types of MPS except MPS IX, however few studies have focused on cardiac alterations in patients with MPS III. METHODS We reviewed medical records, echocardiograms, and electrocardiograms of 26 Taiwanese patients with MPS III (five with IIIA, 20 with IIIB, and one with IIIC; 14 males and 12 females; median age, 7.4 years; age range, 1.8-26.5 years). The relationships between age and each echocardiographic parameter were analyzed. RESULTS Echocardiographic examinations (n = 26) revealed that 10 patients (38%) had valvular heart disease. Four (15%) and eight (31%) patients had valvular stenosis or regurgitation, respectively. The most prevalent cardiac valve abnormality was mitral regurgitation (31%), followed by aortic regurgitation (19%). However, most of the cases of valvular heart disease were mild. Three (12%), five (19%) and five (19%) patients had mitral valve prolapse, a thickened interventricular septum, and asymmetric septal hypertrophy, respectively. The severity of aortic regurgitation and the existence of valvular heart disease, aortic valve abnormalities and valvular stenosis were all positively correlated with increasing age (p < 0.05). Z scores > 2 were identified in 0, 38, 8, and 27% of left ventricular mass index, interventricular septal end-diastolic dimension, left ventricular posterior wall end-diastolic dimension, and aortic diameter, respectively. Electrocardiograms in 11 patients revealed the presence of sinus arrhythmia (n = 3), sinus bradycardia (n = 2), and sinus tachycardia (n = 1). Six patients with MPS IIIB had follow-up echocardiographic data at 1.9-18.1 years to compare with the baseline data, which showed some patients had increased thickness of the interventricular septum, as well as more patients had valvular abnormalities at follow-up. CONCLUSIONS Cardiac involvement in MPS III is less common and milder compared with other types of MPS. The existence of valvular heart disease, aortic valve abnormalities and valvular stenosis in the patients worsened with increasing age, reinforcing the concept of the progressive nature of this disease.
