Abstract Background Hypertension is highly prevalent and is one of the modifiable risk factors for cardiovascular outcomes. Isolated diastolic hypertension (IDH), however, tends to be ignored due to insufficient recognition. We sought to depict the clinical manifestation of IDH and isolated systolic hypertension (ISH) to find a more efficient way to improve the management. Methods Patients with primary hypertension aged over 18 years were investigated from all over the country using convenience sampling during 2017–2019. IDH was defined as systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) ≥90 mmHg. ISH was defined as SBP ≥ 140 mmHg and DBP < 90 mmHg. Results A total of 8548 patients were screened, and 8475 participants were included. The average age was 63.67 ± 12.78 years, and males accounted for 54.4%. Among them, 361 (4.3%) had IDH, and 2096 had ISH (24.7%). Patients with IDH (54.84 ± 13.21 years) were much younger. Aging turned out to be negatively associated with IDH but positively associated with ISH. Multivariate logistic regression analysis showed BMI was a significant risk factor for IDH (OR 1.30, 95%CI 1.05–1.61, p = 0.018), but not for ISH (OR 1.05, 95%CI 0.95–1.16, p = 0.358). Moreover, smoking was significantly associated with IDH (OR 1.36, 95%CI 1.04–1.78, p = 0.026) but not with ISH (OR 1.04, 95%CI 0.90–1.21, p = 0.653). Conclusions Patients with IDH were much younger, and the prevalence decreased with aging. BMI and smoking were remarkably associated with IDH rather than ISH. Keeping fit and giving up smoking might be particularly efficient in the management of young patients with IDH. Trial registration NCT03862183, retrospectively registered on March 5, 2019.

Abstract Objective To investigate the prevalence status of the isolated systolic hypertension (ISH) among the elderly Chinese population and analyze risk factors of ISH. Methods The survey was conducted from September 2015 to September 2016 enrolling 1269 people aging above 80 in the urban community in Chengdu, China. The participants were recruited by using a stratified cluster sampling method. The average blood pressure of an individual was obtained by using a standardized mercury sphygmomanometer to measure the blood pressure twice after a 10-minute seated rest. Results The prevalence of ISH was 53.0% among the elderly population; the ISH was accounted for 82.2% of all hypertension cases. The prevalence of ISH of males and females was 54.7% and 51.5%, respectively, without significant differences (P = 0.25). The prevalence of ISH in the 80–84 group, 85–89 group, and > 90 group were 52.5%, 53.0%, and 60.0%, respectively without significant differences (P for trend = 0.36). Multivariate logistic regression analysis showed that drinking alcoholic, obesity, and heart rate (HR) > 75 beats/min were all positively correlated to the incident of ISH; however, physical exercise was negatively correlated to the occurrence of ISH. Conclusion 53.0% of the elderly Chinese population aged above 80 has ISH. The gender and physical exercise are not the independent risk factor of ISH. But drinking alcoholic, obesity and HR > 75 are significantly related to the occurrence of ISH.

OBJECTIVE The aim of this study was to investigate the clinical and radiological factors associated with the rupture of a vertebral artery dissecting aneurysm (VADA) and to evaluate whether the stagnation sign is a significant risk factor for rupture of VADA. METHODS Clinical and radiological variables of 117 VADAs treated in a tertiary hospital from September 2008 to December 2020 were retrospectively reviewed. The stagnation sign is defined as the finding of contrast agent remaining in the lesion until the venous phase of angiography. Univariate and multivariate analyses were executed to reveal the associations between rupture status and VADA characteristics. RESULTS The rate of ruptured VADAs was 29.1% (34 of 117) and the stagnation sign was observed in 39.3% (46 of 117). Fusiform shape (OR 5.105, 95% CI 1.591–16.383, p = 0.006), irregular surface (OR 4.200, 95% CI 1.412–12.495, p = 0.010), posterior inferior cerebellar artery (PICA) involvement (OR 3.788, 95% CI 1.288–11.136, p = 0.016), and the stagnation sign (OR = 3.317, 95% CI 1.131–9.732, p = 0.029) were significantly related to rupture of VADA in multivariate logistic regression analysis. CONCLUSIONS This study showed that fusiform shape, irregular surface, PICA involvement, and the stagnation sign may be independent risk factors for the rupture of VADA. Therefore, when the potential risk factors are observed in unruptured VADA, more aggressive treatment rather than follow-up or medical therapy may be considered.

AbstractTuberculous empyema (TE) is associated with high mortality and morbidity. In the retrospective cohort study, we aimed to find risk factors for TE among pleural tuberculosis (TB) patients. Between July 2011 and September 2015, all culture-confirmed pleural TB patients (474 cases) were enrolled in our study. Empyema was defined as grossly purulent pleural fluid. Demographic and epidemiological data were collected for further analysis. Multivariate logistic regression analysis was used to evaluate risk factors of TE in pleural TB, age–adjusted odds ratio (OR) and 95% confidence interval (CI) were calculated to show the risk. The mean age was 35.7 ± 18.1 years old, males comprised 79.1% of the participants (375 cases). Forty-seven patients (9.9%) were multidrug-resistant TB (MDR-TB), 29 (6.1%) had retreatment TB, 26 (5.5%) had diabetes mellitus. The percentage of empyema patients was 8.9% (42 cases). Multivariate analysis revealed that male (adjusted OR = 4.431, 95% CI: 1.411, 13.919), pleural adenosine deaminase (ADA, >88 U/L) (adjusted OR = 3.367, 95% CI: 1.533, 7.395) and white blood cell (WBC, >9.52 109/L) (adjusted OR = 5.763, 95% CI: 2.473, 13.431) were significant risk factors for empyema in pleural TB, while pulmonary TB (adjusted OR = 0.155, 95% CI: 0.072, 0.336) was the protective factor for the patients. TE remains a serious threat to public health in China. Male sex is a significant risk factor for TE while the presence of pulmonary TB is protective, and high levels of pleural ADA and WBC count could aid in early diagnosis of TE. This finding would help towards reducing the mortality and morbidity associated with TE.

Abstract Background Acute kidney injury (AKI) is a recognised complication of coronavirus disease 2019 (COVID-19), yet the reported incidence varies widely and the associated risk factors are poorly understood. Methods Data was collected on all adult patients who returned a positive COVID-19 swab while hospitalised at a large UK teaching hospital between 1st March 2020 and 3rd June 2020. Patients were stratified into community- and hospital-acquired AKI based on the timing of AKI onset. Results Out of the 448 eligible patients with COVID-19, 118 (26.3 %) recorded an AKI during their admission. Significant independent risk factors for community-acquired AKI were chronic kidney disease (CKD), diabetes, clinical frailty score and admission C-reactive protein (CRP), systolic blood pressure and respiratory rate. Similar risk factors were significant for hospital-acquired AKI including CKD and trough systolic blood pressure, peak heart rate, peak CRP and trough lymphocytes during admission. In addition, invasive mechanical ventilation was the most significant risk factor for hospital-acquired AKI (adjusted odds ratio 9.1, p < 0.0001) while atrial fibrillation conferred a protective effect (adjusted odds ratio 0.29, p < 0.0209). Mortality was significantly higher for patients who had an AKI compared to those who didn’t have an AKI (54.3 % vs. 29.4 % respectively, p < 0.0001). On Cox regression, hospital-acquired AKI was significantly associated with mortality (adjusted hazard ratio 4.64, p < 0.0001) while community-acquired AKI was not. Conclusions AKI occurred in over a quarter of our hospitalised COVID-19 patients. Community- and hospital-acquired AKI have many shared risk factors which appear to converge on a pre-renal mechanism of injury. Hospital- but not community acquired AKI was a significant risk factor for death.

0019 Untreated isolated systolic hypertension (ISH) indicates arterial stiffening and carries a risk for both stroke and cardiovascular disease. Elevated plasma homocysteine, a metabolite of the essential amino acid methionine, has been linked to vascular stiffness. 187 normotensive (defined as systolic blood pressure (SBP) < 160 mmHg and diastolic blood pressure < 90 mmHg) men and women (mean age 71.29 + 6.3 yrs) were followed for an average of 7 years for incident ISH. ISH was defined as a SBP ≥160 mmHg (while maintaining a DBP of < 90 mmHg) at least one time at 3 year follow-up visits, or the initiation of antihypertensive therapy. The mean baseline systolic and diastolic blood pressures (DBP) were 127 and 69 mmHg, respectively. Over the 7 year period, 59(31.5%) participants developed ISH, 76% qualified by antihypertensive use, and 24% by blood pressure values. The Kaplan Meier Estimate of 7 year survival free from ISH was 67% (95% CI: 61%, 74%). The relationship between incident ISH and the traditional cardiovascular risk factors, creatinine, homocysteine, and carotid artery intima-media wall thickness (IMT) was assessed by Cox proportional hazards regression. The strongest predictor of incident ISH was baseline SBP. For participants with baseline SBPs of < 130, 130-139, and 140+ mmHg, the corresponding 7 year survival free from ISH was 80% (95% CI: 73%, 88% ), 53% (95%CI: 38%, 67%), and 44% (95% CI: 26%, 62%). Factors independently associated with time to ISH were higher triglycerides (upper tertile,RR=2.0, p=0.012), homocysteine levels (> 12.0 μmol/l, RR=2.2, p=0.005), and baseline SBP (per 10 mmHg,RR=1.4, p=0.003). The results were similar when the analysis was restricted to the 157 participants with a baseline SBP of < 140 mmHg. Baseline IMT was found to be univariately related to time to ISH (RR per each 1.0 mm increment=3.0; p=0.016). In multivariate analysis, this association remained independent of triglycerides and homocysteine, but not baseline SBP (RR per each 1.0 mm increment=2.5; p=0.049). In conclusion, among normotensive older adults, 32% can be expected to develop ISH over a 7 year period, and higher triglyceride and homocysteine levels are risk factors.

THE AIM: to identify the frequency and risk factors of cardiovascular lesions in children with ADPKD. PATIENTS AND METHODS: 54 children (27M/27F) with ADPKD were examined. The median age was 12 (IQR: 8.0;15.0) years. Standard two-dimensional echocardiogram was performed. LV mass (LVM) was calculated, normalized to height2.7 and estimated by centile tables. Relative wall thickness (RWT) was calculated. Patterns of abnormal LV geometry were defined as follows: LV concentric remodelling by normal LVMI and RWT ≥0.42; eccentric LV hypertrophy (LVH) by increased LVMI and RWT <0.42; concentric LVH by increased LVMI and RWT ≥0.42. We checked blood pressure with ABPM. Patients were divided into 3 groups according to three levels of BP: hypertension (HBP; greater than the 95th percentile for sex, age, and height), high normal blood pressure (HNBP; 90–95th percentile), and normotension (NBP; less than the 90th percentile). Total kidney volume (cm3) was assessed by ultrasound, corrected for standard body surface and estimated by centile tables. Renal scintigraphy with 99mTc-dimercaptosuccinic acid (DMSA) with the calculation of the integral index of capture (IIC) was performed. RESULTS: Hypertension was found in 42,5 % of cases, HNBP was in 18,5% of cases. HBP were detected more frequently in children with increased renal volume (cm3/1,73m2) more than 97‰+≥50% compared with children with renal volume less than 97‰: (p=0.03), RR=2.9 (95% CI:1.4-4.9). Changes in the structure and geometry of the LV were identified in 14.8% of cases (concentric LVH – 7,4%; eccentric LVH -3,7%; LV concentric remodeling -3,7%). Children with LVMI >90 percentile were more frequently detected systolic hypertension in the daytime, diastolic hypertension at night compared with children with LVMI <90 percentile: 54% vs. 18% (p=0.04), RR=1.81 (95% CI:0.93-3.5) and 55% vs. 16% (p=0.008), RR=2.2 (95% CI:0.98-4.6). LVMI in children with systolic and diastolic hypertension was significantly higher than in children with isolated diastolic hypertension: 34.15 (30.7; 39) vs. 22.77 (22.04; 23.5) (p = 0.03). Increased renal volume (cm3/1,73m2) more than 97‰ and decreased IIC by DMSA were detected more frequently in children with LVMI>90 percentile compared with children with LVMI <90 percentile: (p=0.04), RR=1.7 (95% CI:1.1-2.6) and (р=0.04), RR=1.8 (95% CI:1.1-3.07). CONCLUSION: Risk factor for hypertension in children with ADPKD is increased renal volume. Risk factors for the development of left ventricular hypertrophy are systolic hypertension in the daytime, diastolic hypertension at night, increased kidney volume, and decreased IIC by DMSA.

Background: The aim of this study was to determine the magnitude and significance of the associations between coronary artery calcium (CAC) and different measures of blood pressure among postmenopausal women. Methods: Subjects were a subset of women aged 50 to 59 at baseline in the Women’s Health Initiative (WHI) clinical trial of conjugated equine estrogen (CEE) who underwent a one-time computed tomography (CT) scan of the chest following the end of the trial to determine CAC. At the baseline WHI clinic visit, CEE trial participants provided data on a wide range of factors to include blood pressure measurements which were measured twice with the participant in the seated position using a conventional mercury sphygmomanometer and appropriately sized cuffs. Results: The sample consisted of 1,064 women with a mean age of 55.1 (2.8) years at WHI randomization and 64.8 (2.9) years at CAC ascertainment. The prevalence of a CAC score > 0 was 47%, while the prevalence of a CAC score >= 10 and > 100 was 39 and 19%, respectively. There was a linear association between the log-odds of any CAC and SBP while there was a curvilinear and inverse association with DBP that was independent of CVD risk factors and blood pressure medication status. For any value of diastolic blood pressure, the probability of CAC increased with higher levels of SBP. Conversely, for any given value of SBP, the probability of any CAC decreased with higher levels of DBP. Those with a PP >= 55 mmHg had nearly a two-fold higher odds for having any CAC (Odds Ratio: 1.95, 95% CI: 1.24 – 3.06) while individuals with isolated systolic hypertension (SBP >= 140 and DBP < 90) had a 73% higher odds for CAC (95% CI: 1.03 – 2.90, p = 0.04) independent of other risk factors and blood pressure medication status. There was no significant associations between mean arterial pressure and CAC. Conclusions: In postmenopausal women over the age of 50 years, both SBP and DBP are relevant for determining the risk for coronary artery calcium. Notably, higher levels of pulse pressure and systolic blood pressure were strong determinants of CAC, while diastolic blood pressure was inversely related. Consequently, isolated systolic hypertension may be relevant in women. These results may be of clinical relevance for the prevention of coronary artery disease.
