Patients with Dipper and Nondipper High-Normal Blood Pressure Were Associated with Left Ventricular Mass

Purpose. High-normal blood pressure has been suggested to associate with target organ damage and higher left ventricular mass index (LVMI). Our aim is to find the association between people with high-normal blood pressure and their left ventricular mass index. Materials and Methods. Given a total of 181 people with office blood pressure, 24-hour ambulatory blood pressure monitoring, 35 of them are normotensive (BP < 130/85 mm Hg), and 146 people with high-normal blood pressure (BP 130–139/85–89 mm Hg), divide the high-normal blood pressure group into dipper and nondipper according to their ABPM in 24 hours. All of them were performed with echocardiography to calculate LVMI. Results. After adjusting for potential confounding factors, mean systolic blood pressure (BP) of the nondipper group is (119 + 9) mmHg in 24 h, which is significantly higher ( p < 0.05) than in the dipper group (116 + 11) mmHg, indicating the mean systolic BP is associated with the dipper type ( p < 0.05); furthermore, the higher nocturnal blood pressure is associated with the nondipper group significantly ( p < 0.05), and LVMI ((121 ± 11) g/m2) of the nondipper group is also significantly higher than in the dipper group’s LVMI ((108 ± 12) g/m2) ( p < 0.05). The multivariate linear regression analyses revealed significant and independent associations of LVMI with these factors: triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL-C), and coefficient of variation of systolic and diastolic blood pressure in 24 hours. Conclusion. After multiple relevant clinical confounding factors were adjusted, patients with dipper and nondipper high-normal blood pressure had higher LVMI. Abnormalities in circadian blood pressure variability may be associated with the left ventricular hypertrophy.

Cardiovascular Morbidity and Mortality in Adult Patients With Repaired Aortic Coarctation

Background The long‐term burden of cardiovascular disease after repair of coarctation of the aorta (CoA) has not been elucidated. We aimed to determine the incidence of and risk factors for cardiovascular events in adult patients with repaired CoA. Additionally, mortality rates were compared between adults with repaired CoA and the general population. Methods and Results Using the Dutch Congenital Corvitia (CONCOR) registry, patients aged ≥16 years with previous surgical or transcatheter CoA repair from 5 tertiary referral centers were included. Cardiovascular events were recorded, comprising coronary artery disease, stroke/transient ischemic attack, aortic complications, arrhythmias, heart failure hospitalizations, endocarditis, and cardiovascular death. In total, 920 patients (median age, 24 years [range 16–74 years]) were included. After a mean follow‐up of 9.3±5.1 years, 191 patients (21%) experienced at least 1 cardiovascular event. A total of 270 cardiovascular events occurred, of which aortic complications and arrhythmias were most frequent. Older age at initial CoA repair (hazard ratio [HR], 1.017; 95% CI, 1.000–1.033 [ P =0.048]) and elevated left ventricular mass index (HR, 1.009; 95% CI, 1.005–1.013 [ P <0.001]) were independently associated with an increased risk of cardiovascular events. The mortality rate was 3.3 times higher than expected based on an age‐ and sex‐matched cohort from the Dutch general population (standardized mortality ratio, 3.3; 95% CI, 2.3–4.4 [ P <0.001]). Conclusions This large, prospective cohort of adults with repaired CoA showed a high burden of cardiovascular events, particularly aortic complications and arrhythmias, during long‐term follow‐up. Older age at initial CoA repair and elevated left ventricular mass index were independent risk factors for the occurrence of cardiovascular events. Mortality was 3.3‐fold higher compared with the general population. These results advocate stringent follow‐up after CoA repair and emphasize the need for improved preventive strategies.

Correlation between Non-Alcoholic Fatty Liver Disease (NAFLD) fibrosis score (NFS) with Left Ventricular Mass Index (LVMI) in patients with NAFLD

Background: Cardiovascular-related mortality is a major concern in NAFLD. Advanced fibrosis was known to be associated with cardiovascular diseases. NAFLD Fibrosis Score (NFS) is used to identify the development of liver fibrosis in NAFLD patients. Left ventricular mass index (LVMI) is a sign of subclinical cardiovascular complications in NAFLD. The correlation between NAFLD fibrosis score with LVMI in NAFLD patients is not fully established.Objective: To analyze the correlation between NAFLD fibrosis score with LVMI in NAFLD patients.Methods: A cross-sectional study of NAFLD patients in Kariadi Hospital Indonesia. NFS was done using a formula based on clinical and biochemical parameters. LVMI was measured with echocardiography. Pearson’s, Mann-Whitney, and logistic regression were used for analysis.Results: A total of 64 patients with primary NAFLD were enrolled, 54.7% males and 45.3% females. Mean age was 52,8 ± 10,5 years (30-77 years). Based on NFS criteria, high probability group was the highest (50%), followed by intermediate probability group (34,4%) and low probability group (15,6%). Highest increase in LVMI was obtained in the high probability group (93,8%), followed by intermediate probability (59,1%), and low probability group (10%) respectively. There was significant correlation between NFS and LVMI (P 0,002). Logistic regression showed that NFS has a more significant correlation with LVMI compared to gender (P=0,002).Conclusion: NFS is a non‐invasive liver fibrosis scores which independently corelated with Left ventricular mass index (LVMI), a marker of cardiovascular abnormality.

Two-Year Change in Blood Pressure Status and Left Ventricular Mass Index in Chinese Children

Background: Elevated blood pressure (BP) is associated with target organ damage, such as left ventricular hypertrophy (LVH), in childhood. However, it is unclear if children who resolve elevated BP have reduced levels of left ventricular mass index (LVMI). This study aimed to examine the association between change in BP status over 2 years and LVMI among Chinese children.Methods: Data were from 1,183 children aged 6–11 years at baseline in 2017 who were followed up in 2019 in the Huantai Childhood Cardiovascular Health Cohort Study. Change in BP status over 2 years from baseline to follow-up was categorized as: persistent normal BP, resolved elevated BP (elevated BP at baseline, normal BP at follow-up), incident elevated BP (normal BP at baseline, elevated BP at follow-up), and persistent elevated BP. Elevated BP status was defined according to national reference standards as systolic or diastolic BP levels ≥ sex-, age-, and height-specific 95th percentiles.Results: LVMI levels were lowest in children with persistent normal BP (30.13 g/m2.7), higher in those with incident elevated BP (31.27 g/m2.7), and highest in those with persistent elevated BP (33.26 g/m2.7). However, LVMI levels in those who had resolved elevated BP (30.67 g/m2.7) were similar to those with persistent normal BP. In the fully adjusted model, compared with children with persistent normal BP, those with persistent elevated BP and incident elevated BP had higher LVMI at follow-up (ß = 3.131, p &lt; 0.001; ß = 1.143, p = 0.041, respectively). In contrast, those who had resolved elevated BP did not have a significantly higher LVMI (ß = 0.545, p = 0.194) than those with persistent normal BP.Conclusion: Developing or maintaining elevated BP over a 2-year period in childhood associated with higher levels of LVMI, but those able to resolve their elevated BP status over the same period had LVMI levels that were similar with those who had normal BP at both time points. Thus, it is important to identify children with elevated BP at early time and to take effective measures to lower their BP levels, thereby reducing high LVMI levels and related cardiovascular diseases in the future.

Mục tiêu: Nhận xét thay đổi chỉ số khối cơ thất trái (Left ventricular mass index: LVMI) và yếu tố liên quan ở bệnh nhân thay van điều trị hẹp van động mạch chủ tại Bệnh viện Trung ương Quân đội 108. Đối tượng và phương pháp: 67 bệnh nhân được phẫu thuật thay van điều trị hẹp van động mạch chủ. Nghiên cứu mô tả, không đối chứng với các biến số: LVMI, xác suất LVMI trở về bình thường sau mổ, phân tích R các yếu tố tương quan như tăng huyết áp, đái tháo đường, bất tương hợp van - bệnh nhân (PPM),… Kết quả: LVMI giảm có ý nghĩa sau mổ với p<0,05. Xác suất ước tính LVMI về bình thường ở tháng 24 là 55%, tháng 48 là 37,9%. LVMI theo dõi trung hạn tương quan tuyến tính với trước mổ (r = 0,44, p<0,001).
