    Abstract: The uptake of proven stroke treatments varies widely. We aimed to determine the association of evidence‐based processes of care for acute ischemic stroke ( AIS ) and clinical outcome of patients who participated in the HEADPOST (Head Positioning in Acute Stroke Trial), a multicenter cluster crossover trial of lying flat versus sitting up, head positioning in acute stroke. Methods and Results Use of 8 AIS processes of care were considered: reperfusion therapy in eligible patients; acute stroke unit care; antihypertensive, antiplatelet, statin, and anticoagulation for atrial fibrillation; dysphagia assessment; and physiotherapist review. Hierarchical, mixed, logistic regression models were performed to determine associations with good outcome (modified Rankin Scale scores 0–2) at 90 days, adjusted for patient and hospital variables. Among 9485 patients with AIS, implementation of all processes of care in eligible patients, or “defect‐free” care, was associated with improved outcome (odds ratio, 1.40; 95% CI, 1.18–1.65) and better survival (odds ratio, 2.23; 95% CI , 1.62–3.09). Defect‐free stroke care was also significantly associated with excellent outcome (modified Rankin Scale score 0–1) (odds ratio, 1.22; 95% CI , 1.04–1.43). No hospital characteristic was independently predictive of outcome. Only 1445 (15%) of eligible patients with AIS received all processes of care, with significant regional variations in overall and individual rates. Conclusions Use of evidence‐based care is associated with improved clinical outcome in AIS . Strategies are required to address regional variation in the use of proven AIS treatments.

    Abstract: Multiple genetic loci associated with lipid levels have been identified predominantly in Europeans, and the issue of to what extent these genetic loci can predict blood lipid levels increases over time and the incidence of future hyperlipidemia remains largely unknown. Methods and Results— We conducted a meta-analysis of genome-wide association studies of lipid levels in 8344 subjects followed by replication studies including 14 739 additional individuals. We replicated 17 previously reported loci. We also newly identified 3 Chinese-specific variants in previous regions ( HLA-C , LIPG , and LDLR ) with genome-wide significance. Almost all the variants contributed to lipid levels change and incident hyperlipidemia 〉 8.1-year follow-up among 6428 individuals of a prospective cohort study. The strongest associations for lipid levels change were detected at LPL , TRIB1 , APOA1-C3-A4-A5 , LIPC , CETP , and LDLR ( P range from 4.84×10 −4 to 4.62×10 −18 ), whereas LPL , TRIB1 , ABCA1 , APOA1-C3-A4-A5 , CETP , and APOE displayed significant strongest associations for incident hyperlipidemia ( P range from 1.20×10 −3 to 4.67×10 −16 ). The 4 lipids genetic risk scores were independently associated with linear increases in their corresponding lipid levels and risk of incident hyperlipidemia. A C -statistics analysis showed significant improvement in the prediction of incident hyperlipidemia on top of traditional risk factors including the baseline lipid levels. Conclusions— These findings identified some evidence for allelic heterogeneity in Chinese when compared with Europeans in relation to lipid associations. The individual variants and those cumulative effects were independent risk factors for lipids increase and incident hyperlipidemia.

    Abstract: Although multiple genetic markers associated with blood pressure have been identified by genome-wide association studies, their aggregate effect on risk of incident hypertension and cardiovascular disease is uncertain, particularly among East Asian who may have different genetic and environmental exposures from Europeans. We aimed to examine the association between genetic predisposition to higher blood pressure and risk of incident hypertension and cardiovascular disease in 26 262 individuals in 2 Chinese population-based prospective cohorts. A genetic risk score was calculated based on 22 established variants for blood pressure in East Asian. We found the genetic risk score was significantly and independently associated with linear increases in blood pressure and risk of incident hypertension and cardiovascular disease ( P range from 4.57×10 –3 to 3.10×10 –6 ). In analyses adjusted for traditional risk factors including blood pressure, individuals carrying most blood pressure–related risk alleles (top quintile of genetic score distribution) had 40% (95% confidence interval, 18–66) and 26% (6–45) increased risk for incident hypertension and cardiovascular disease, respectively, when compared with individuals in the bottom quintile. The genetic risk score also significantly improved discrimination for incident hypertension and cardiovascular disease and led to modest improvements in risk reclassification for cardiovascular disease (all the P 〈 0.05). Our data indicate that genetic predisposition to higher blood pressure is an independent risk factor for blood pressure increase and incident hypertension and cardiovascular disease and provides modest incremental information to cardiovascular disease risk prediction. The potential clinical use of this panel of blood pressure–associated polymorphisms remains to be determined.

    Abstract: Recent genome-wide association studies have identified that genetic variants in the SLC22A3-LPAL2-LPA gene cluster influence plasma lipoprotein(a) [Lp(a)] concentration. However, the association between this gene cluster and the severity of coronary artery disease (CAD), especially the potential underlying mechanism, remains unclear. The purpose of this study was to investigate the association between variation in the SLC22A3-LPAL2-LPA gene cluster and CAD. Approach and Results— We performed 2-stage case–control studies in a Chinese Han population. The variant genotypes were examined for their association with both Lp(a) level and severity of CAD. Putative mechanisms were also evaluated. One single nucleotide polymorphism, rs3088442, in the SLC22A3-LPAL2-LPA gene cluster was significantly associated with both plasma Lp(a) levels and CAD severity. The gene dosage of the risk allele at rs3088442 indicated a robust association with left main trunk disease ( P =0.046), number of vascular lesions ( P =4.5×10 –3 ), and Gensini scores ( P =0.012) in patients with CAD. Reporter gene analysis indicated that the rs3088442 G allele might suppress miR-147a binding to the 3′ untranslated region of SLC22A3 , resulting in altered SLC22A3 and LPA gene expression ( P =0.015 and 9.2×10 –6 , respectively), possibly explaining the increased plasma Lp(a) levels and risk of CAD. Conclusions— The genotype of rs3088442 within the SLC22A3-LPAL2-LPA gene cluster may contribute to regulation of plasma Lp(a) levels and possibly to the severity of CAD in a Chinese Han population.

    Abstract: Blood pressure (BP) responses to dietary sodium and potassium intervention and cold pressor test vary considerably among individuals. We aimed to identify novel genetic variants influencing individuals’ BP responses to dietary intervention and cold pressor test. Methods and Results— We conducted a genome-wide association study of BP responses in 1881 Han Chinese and de novo genotyped top findings in 698 Han Chinese. Diet-feeding study included a 7-day low-sodium (51.3 mmol/d), a 7-day high-sodium (307.8 mmol/d), and a 7-day high-sodium plus potassium supplementation (60 mmol/d). Nine BP measurements were obtained during baseline observation and each intervention period. The meta-analyses identified 8 novel loci for BP phenotypes, which physically mapped in or near PRMT6 ( P =7.29×10 –9 ), CDCA7 ( P =3.57×10 –8 ), PIBF1 ( P =1.78×10 –9 ), ARL4C ( P =1.86×10 –8 ), IRAK1BP1 ( P =1.44×10 −10 ), SALL1 ( P =7.01×10 –13 ), TRPM8 ( P =2.68×10 –8 ), and FBXL13 ( P =3.74×10 –9 ). There was a strong dose–response relationship between the number of risk alleles of these independent single-nucleotide polymorphisms and the risk of developing hypertension during the 7.5-year follow-up in the study participants. Compared with those in the lowest quartile of risk alleles, odds ratios (95% confidence intervals) for those in the second, third, and fourth quartiles were 1.39 (0.97, 1.99), 1.72 (1.19, 2.47), and 1.84 (1.29, 2.62), respectively ( P =0.0003 for trend). Conclusions— Our study identified 8 novel loci for BP responses to dietary sodium and potassium intervention and cold pressor test. The effect size of these novel loci on BP phenotypes is much larger than those reported by the previously published studies. Furthermore, these variants predict the risk of developing hypertension among individuals with normal BP at baseline.

    Abstract: Hypoalbuminemia was extensively used to diagnose malnutrition in older adults. Malnutrition was associated with mortality in elderly patients with cardiovascular diseases. The relationship between hypoalbuminemia and clinical outcomes in elderly patients with nonischemic dilated cardiomyopathy (NIDCM) remains unknown. Methods A total of 1058 consecutive patients with NIDCM (age ≥60 years) were retrospectively enrolled from January 2010 to December 2019. Univariate and multivariate analyses were performed to assess the association of hypoalbuminemia with clinical outcomes. Results Patients with hypoalbuminemia were older (69.29 ± 6.67 vs. 67.61 ± 5.90 years, P   〈  0.001) and had higher prevalence of in-hospital and long-term death than those without (6.9 vs. 1.7%, 50.7 vs. 35.2%, P   〈  0.001). Logistic regression analysis showed that hypoalbuminemia was significantly related to in-hospital death [odds ratio (OR): 4.334, 95% confidence interval (CI): 2.185–8.597, P   〈  0.001]. Kaplan–Meier survival analysis showed that patients with hypoalbuminemia had worse prognosis than those with nonhypoalbuminemia (log-ran k χ 2 28.96, P   〈  0.001). After adjusting for age, serum creatinine, HDL-C, AST/ALT hypoalbuminemia, LVEF and diabetes, hypoalbuminemia remained an independent predictor for long-term death (hazard ratio 1.322, 95% CI 0.046–1.670, P  = 0.019). Conclusion Hypoalbuminemia was associated with increased risk of in-hospital and long-term mortality in elderly patients with NIDCM.

    Abstract: The purpose of our study is to examine the correlation between sleep factors and the prevalence of kidney stones in US adults. A total of 34,679 participants from the National Health and Nutrition Examination Survey 2007 to 2018 were included in the analyses. Sleep data collection included: presleep factors (difficulty falling asleep, sleep onset latency), intra-sleep factors (risk index of obstructive sleep apnea, restless leg syndrome, difficulty maintaining sleep), post-sleep factors (daytime sleepiness, non-restorative sleep), sleep schedule and duration, and sleep quality. Logistic regression models were used to analyze the correlation between sleep factors and the prevalence of kidney stones. Among the 34,679 participants, the overall incidence of kidney stones was 9.3%. The presence of presleep factors (difficulty falling asleep [odds ratios [OR], 1.680; 95% CI, 1.310–2.150] , prolonged sleep onset latency [OR, 1.320; 95% CI, 1.020–1.700]), intra-sleep factors (higher risk index of obstructive sleep apnea [OR, 1.750; 95% CI, 1.500–2.050] , restless leg syndrome [OR, 1.520; 95% CI, 1.150–1.990], difficulty maintaining sleep [OR, 1.430; 95% CI, 1.130–1.810] ), post-sleep factors (daytime sleepiness [OR, 1.430; 95% CI, 1.220–1.680], non-restorative sleep [OR, 1.400; 95% CI, 1.110–1.760] ), short sleep duration (OR, 1.190; 95% CI, 1.080–1.310), mediate sleep quality (OR, 1.140; 95% CI, 1.020–1.290), and poor sleep quality (OR, 1.500; 95% CI, 1.310–1.720) are linked to the occurrence of kidney stones. However, short sleep onset latency, bedtime and wake-up time were not significantly associated with the prevalence of kidney stones. These findings showed positive associations between higher kidney stone prevalence and poor sleep factors.
