OBJECTIVE:Daytime napping has been reported to have a potential association with an increased risk of cardiovascular diseases (CVDs) in several cohort studies, but the causal effects are unclear. In this study, we aimed to investigate the relationship between daytime napping and CVDs, as well as to validate causality in this relationship by Mendelian randomization (MR).METHODS:A two-sample MR method was used to evaluate the causal effect of daytime napping on CVDs. The exposure of daytime napping was extracted from publicly available genome-wide association studies (GWASs) in the UK Biobank, and the outcomes of 14 CVDs were obtained from the FinnGen consortium. A total of 49 single-nucleotide polymorphisms (SNPs) were used as the instrumental variables. The effect estimates were calculated by using the inverse-variance weighted method.RESULTS:The MR analyses showed that genetically predicted daytime napping was associated with an increased risk of five CVDs, including heart failure (odds ratio (OR): 1.71, 95% CI: 1.19-2.44, p = 0.003), hypertension (OR: 1.51, 95% CI: 1.05-2.16, p = 0.026), atrial fibrillation (OR: 1.71, 95% CI: 1.02-2.88, p = 0.042), cardiac arrythmias (OR: 1.47, 95% CI: 1.47, 95% CI: 1.01-2.13, p = 0.042) and coronary atherosclerosis (OR: 1.77, 95% CI: 1.17-2.68, p = 0.006). No significant influence was observed for other CVDs.CONCLUSION:This two-sample MR analysis suggested that daytime napping was causally associated with an increased risk of heart failure, hypertension, atrial fibrillation, cardiac arrythmias and coronary atherosclerosis.

Objective:To examine the joint association of healthy lifestyles and statin use with all-cause and cardiovascular mortality in high-risk individuals, and evaluate the survival benefits by life expectancy.Methods:During 2015-2021, participants aged 35-75 years were recruited by the China Health Evaluation And risk Reduction through nationwide Teamwork. Based on number of healthy lifestyles related to smoking, alcohol drinking, physical activity, and diet, we categorized them into: very healthy (3-4), healthy (2), and unhealthy (0-1). Statin use was determined by self-report taking statin in last two weeks.Results:Among the 265,209 included participants at high risk, 6979 deaths were observed, including 3236 CVD deaths during a median 3.6 years of follow-up. Individuals taking statin and with a very healthy lifestyle had the lowest risk of all-cause (HR: 0.70; 95 %CI: 0.57-0.87) and cardiovascular mortality (0.56; 0.40-0.79), compared with statin non-users with an unhealthy lifestyle. High-risk participants taking statin and with a very healthy lifestyle had the highest years of life gained (5.90 years at 35-year-old [4.14-7.67; P < 0.001]) compared with statin non-users with an unhealthy lifestyle among high-risk people. And their life expectancy was comparable with those without high risk but with a very healthy lifestyle (4.49 vs. 4.68 years).Conclusion:The combination of preventive medication and multiple healthy lifestyles was associated with lower risk of all-cause and cardiovascular mortality and largest survival benefits. Integrated strategy to improve long-term health for high-risk people was urgently needed.

INTRODUCTION:Exploring sociodemographic effect modification is important to provide evidence for developing targeted recommendations and reducing health inequalities. This study evaluated how sociodemographic factors including age, sex, race/ethnicity and socioeconomic status (SES) modify the association between leisure-time physical activity (LTPA) and all-cause and major cause-specific mortality.METHODS:The study sample included 471,992 people from the 1997-2018 National Health Interview Survey (NHIS) and 41,830 people from the 1999-2018 National Health and Nutrition Examination Survey (NHANES). Data were analyzed in December 2022. Mortality data from the National Death Index were available to December 31, 2019. Sufficient LTPA was defined as at least 150 minutes of moderate and/or vigorous intensity per week.RESULTS:There were 46,289 deaths in NHIS participants and 4,617 deaths in NHANES participants during a mean follow-up of 10 years. Individuals with sufficient LTPA had lower risk of all-cause (NHIS: hazard ratio, 0.74, 95% CI: [0.74-0.74]; NHANES: 0.73 [0.68-0.79]) and cardiovascular mortality (NHIS: 0.75 [0.75-0.75]; NHANES: 0.80 [0.69-0.93]) compared with inactive participants. The subgroup analysis showed significant interactions between LTPA and all sociodemographic factors. Associations between LTPA and mortality were weaker among younger individuals, males, Hispanic adults or those of low SES, respectively.CONCLUSIONS:Sociodemographic factors significantly modified the associations between LTPA and mortality. The health benefits of sufficient LTPA were smaller in younger individuals, males, Hispanic adults or those of low SES. These findings can help identify target populations for promotion of physical activity to reduce health inequalities and the development of physical activity guidelines.

AIMS:There is an increasing proportion of hospitalized heart failure (HF) patients classified as HF with preserved ejection fraction (HFpEF) around the world. Growth differentiation factor 15 (GDF-15) is a promising biomarker in HFpEF prognostication; however, the majority of the existing data has been derived from the research on undifferentiated HF, whereas the studies focusing on HFpEF are still limited. This study aimed to determine the prognostic power of GDF-15 in the hospitalized patients with HFpEF in a Chinese cohort.METHODS AND RESULTS:We analysed the levels of serum GDF-15 in 380 patients hospitalized for acute onset of HFpEF measured by heart ultrasound at admission in a prospective cohort. The associations of GDF-15 with 1 year risk of all-cause death and 1 year HF readmission were assessed by the Cox proportional hazards model. Area under the receiver operating characteristic curves was used to compare predictive accuracy. GDF-15 was strongly correlated with 1 year HF readmission and 1 year all-cause death, with event rates of 24.8%, 40.0%, and 50.0% for 1 year HF readmission (P < 0.001), respectively, and with 11.2%, 13.6%, and 24.6% for 1 year all-cause death (P = 0.004) in the corresponding tertile, respectively. In the multivariate linear regression model, GDF-15 had a significantly negative correlation with haemoglobin (P = 0.01) and a positive correlation with creatinine (P = 0.01), alanine transaminase (P = 0.001), and therapy of aldosterone antagonist (P = 0.018). The univariate Cox regression model of GDF-15 showed that c-statistic was 0.632 for 1 year HF readmission and 0.644 for 1 year all-cause death, which were superior to the N-terminal pro-brain natriuretic peptide (NT-proBNP) model with c-statistics of 0.595 and 0.610, respectively. In the multivariable Cox regression model, GDF-15 tertiles independently predicted 1 year HF readmission (hazard ratio 2.25, 95% confidence interval: 1.43-3.54, P < 0.001) after adjusting for baseline Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure (ASCEND-HF) risk score, history of HF, NT-proBNP, and high-sensitivity cardiac troponin T. Compared with the model including all the adjusted variables, the model with the addition of GDF-15 improved predictive power, with c-statistic increasing from 0.643 to 0.657 for 1 year HF readmission and from 0.638 to 0.660 for 1 year all-cause death.CONCLUSIONS:In hospitalized patients with HFpEF, GDF-15 measured within 48 h of admission is a strong independent biomarker for 1 year HF readmission and even better than NT-proBNP. GDF-15 combined with the traditional indicators provided incremental prognostic value in this population.

BACKGROUND:Since 2010, China has made vast financial investments and policy changes to the primary care system. We aimed to assess how hypertension awareness, treatment, and control might be used to assess quality of primary care systems, which reflect the outcomes of public health services and medical care.METHODS:We used The China Patient-centred Evaluative Assessment of Cardiac Events Million Persons Project, a government-funded public health project that focuses on cardiovascular disease risk in China. We linked primary care institution characteristics that were captured in the survey between 2016 and 2017 to the participant-level data gathered in baseline visits between 2014 and 2021. Participants were included if they had hypertension and lived in the towns or streets that took part in the primary care survey. Participants were excluded if they had missing data for blood pressure measurement, history of hypertension, sex, or age. Primary care institutions were excluded if the catchment area had fewer than 100 participants with hypertension. Hypertension awareness was defined as the proportion of participants with hypertension who self-reported a hypertension diagnosis. Hypertension treatment was defined as the proportion of participants who currently use antihypertensive medications among those who were aware. Hypertension control was defined as the proportion of participants with an average systolic blood pressure less than 140 mm Hg and an average diastolic blood pressure less than 90 mm Hg over two readings among those who were treated during the study. All patients were included in the analysis. This trial was registered at ClinicalTrials.gov, NCT02536456.FINDINGS:Between Sept 15, 2014, and March 16, 2021, we assessed 503 township-level primary care institutions for eligibility. 70 institutions were excluded as they could not be linked with individual data or because their catchment area had fewer than 100 participants with hypertension. We analysed 433 township-level primary care institutions across all 31 provinces of mainland China, including 660 565 individuals with hypertension in their catchment areas. Across townships, age-sex standardised hypertension awareness varied from 8·2% to 81·0%, treatment varied from 2·6% to 96·5%, and control proportions varied from 0% to 62·4%. Hypertension awareness, treatment, and control were significantly associated with the following institutional characteristics: government funding through balance allocation (ie, institutions have their human resources funded by local government, but need to be self-supporting in other aspects; awareness odds ratio 0·88, 95% CI 0·78-0·99; p=0·027), having financial problems that interrupted routine service delivery (awareness 0·81, 0·72-0·92; p=0·0007, control 0·84; 0·75-0·94, p=0·0034), setting performance-based bonus (treatment 1·39, 1·07-1·80; p=0·013), basic salary defined by number of patient visits (control 0·85, 0·76-0·95; p=0·0053), using electronic referrals (treatment 1·41, 1·14-1·73; p=0·0012, control 1·17; 1·03-1·33, p=0·014), implementing family physician contract services (awareness 1·13, 1·00-1·28; p=0·045, control 1·30; 1·15-1·46, p<0·0001), and proportion of physicians who are formally licensed (awareness per 10% increase 1·04, 1·01-1·08; p=0·019, treatment 1·08; 1·02-1·14, p=0·0077; control per 10% increase 1·07, 1·03-1·10; p=0·0006).INTERPRETATION:The role of primary care role in hypertension management might benefit from new strategies that promote best practices in institutional financing, performance appraisal, service delivery, and information technology.FUNDING:Chinese Academy of Medical Sciences Innovation Fund for Medical Science, and the National High Level Hospital Clinical Research Funding.TRANSLATION:For the Chinese translation of the abstract see Supplementary Materials section.

AIMS:The beneficial effect of β-blocker on heart failure with reduced ejection fraction is well established. However, its effect on the 1-year outcome of heart failure with mid-range ejection fraction (HFmrEF) remains unclear.METHODS AND RESULTS:We analysed the data of the patients with left ventricular ejection fraction (LVEF) between 40% and 49% in China Patient-centred Evaluative Assessment of Cardiac Events Prospective Heart Failure Study (China PEACE 5p-HF Study), in which patients hospitalized for heart failure from 52 Chinese hospitals were recruited from 2016 to 2018. Two primary outcomes were all-cause death and all-cause hospitalization. The associations between β-blocker use at discharge and outcomes were assessed by inverse probability of treatment weighting (IPTW)-weighted Cox regression analyses. To assess consistency, IPTW adjusting medications analyses, multivariable analyses and dose-effect analyses were performed. A total of 1035 HFmrEF patients were included in the analysis. The mean age was 65.5 ± 12.7 years and 377 (36.4%) were female. The median (interquartile range) of LVEF was 44% (42-47%). Six hundred and sixty-one (63.8%) were treated with β-blocker. Patients using β-blocker were younger with better cardiac function, and more likely to use renin-angiotensin system inhibitor and mineralocorticoid receptor antagonist. During the 1-year follow-up, death occurred in 84 (12.7%) treated and 85 (22.7%) untreated patients (P < 0.0001); all-cause hospitalization occurred in 298 (45.1%) treated and 188 (50.3%) untreated patients (P = 0.04). After IPTW-weighted adjustment, β-blocker use was significantly associated with lower risk of all-cause death [hazard ratio (HR): 0.70; 95% confidence interval (CI): 0.51-0.96, P = 0.03], but not with lower all-cause hospitalization (HR, 0.92, 95% CI, 0.76-1.10, P = 0.36). Consistency analyses showed consistent favourable effect of β-blocker on all-cause death, but not on all-cause hospitalization.CONCLUSIONS:Among patients with HFmrEF, β-blocker use was associated with lower risk of all-cause death, but not with lower risk of all-cause hospitalization.

Background:High systolic blood pressure (SBP) is an important risk factor for the progression of heart failure (HF); however, the association between SBP and prognosis among patients with established HF was uncertain. This study aimed to investigate the association between SBP and long-term clinical outcomes in patients hospitalized for HF.Methods:This study prospectively enrolled adult patients hospitalized for HF in 52 hospitals from 20 provinces in China. SBPs were measured in a stable condition judged by clinicians during hospitalization before discharge according to the standard research protocol. The primary outcomes included 1-year all-cause death and HF readmission. The multivariable Cox proportional hazards regression models were fitted to examine the association between SBP and clinical outcomes. Restricted cubic splines were used to examine the non-linear associations.Results:The 4,564 patients had a mean age of 65.3 ± 13.5 years and 37.9% were female. The average SBP was 123.2 ± 19.0 mmHg. One-year all-cause death and HF readmission were 16.9 and 32.7%, respectively. After adjustment, patients with SBP < 110 mmHg had a higher risk of all-cause death compared with those with SBP of 130-139 mmHg (HR 1.71; 95% CI: 1.32-2.20). Patients with SBP < 110 mmHg (HR 1.36; 95% CI: 1.14-1.64) and SBP ≥ 150 mmHg (HR 1.26; 95% CI: 1.01-1.58) had a higher risk of HF readmission, and the association between SBP and HF readmission followed a J-curve relationship with the nadir SBP around 130 mmHg. These associations were consistent regardless of age, sex, left ventricular ejection fraction, hypertension, coronary heart disease, and medications for HF.Conclusion:In patients hospitalized for HF, lower SBP in a stable phase during hospitalization portends an increased risk of 1-year death, and a J-curve association has been observed between SBP and 1-year HF readmission. These associations were consistent among clinically important subgroups.

Background:Individual non-cardiac comorbidities are prevalent in HF; however, few studies reported how the aggregate burden of non-cardiac comorbidities affects long-term outcomes, and it is unknown whether this burden is associated with changes in health status.Aims:To assess the association of the overall burden of non-cardiac comorbidities with clinical outcomes and quality of life (QoL) in patients hospitalized for heart failure (HF).Methods:We prospectively enrolled patients hospitalized for HF from 52 hospitals in China. Eight key non-cardiac comorbidities [diabetes, chronic renal disease, chronic obstructive pulmonary disease (COPD), anemia, stroke, cancer, peripheral arterial disease (PAD), and liver cirrhosis] were included, and patients were categorized into four groups: none, one, two, and three or more comorbidities. We fitted Cox proportional hazards models to assess the burden of comorbidities on 1-year death and rehospitalization.Results:Of the 4,866 patients, 25.3% had no non-cardiac comorbidity, 32.2% had one, 22.9% had two, and 19.6% had three or more in China. Compared with those without non-cardiac comorbidities, patients with three or more comorbidities had higher risks of 1-year all-cause death [heart rate, HR 1.89; 95% confidence interval (CI) 1.48-2.39] and all-rehospitalization (HR 1.35; 95%CI 1.15-1.58) after adjustment. Although all patients with HF experienced a longitudinal improvement in QoL in the 180 days after discharge, those with three or more non-cardiac comorbidities had an unadjusted 11.4 (95%CI -13.4 to -9.4) lower Kansas City Cardiomyopathy Questionnaire (KCCQ) scores than patients without comorbidities. This difference decreased to -6.4 (95%CI -8.6 to -4.2) after adjustment for covariates.Conclusion:Among patients hospitalized with HF in this study, a higher burden of non-cardiac comorbidities was significantly associated with worse health-related QoL (HRQoL), increased risks of death, and rehospitalization post-discharge. The findings highlight the need to address the management of comorbidities effectively in standardized HF care.

BACKGROUND:The association between heart rate and 1-year clinical outcomes in heart failure (HF) patients with atrial fibrillation (AF), and whether this association depends on left ventricular ejection fraction (LVEF), are unclear. We investigated the relationship between discharge heart rate and 1-year clinical outcomes after discharge among hospitalized HF patients with AF, and further explored this association that differ by LVEF level.METHODS:In this analysis, we enrolled 1760 hospitalized HF patients with AF from the China Patient-centered Evaluative Assessment of Cardiac Events Prospective Heart Failure study from August 2016 to May 2018. Patients were categorized into three groups with low (<65 beats per minute [bpm]), moderate (65-85 bpm), and high (≥86 bpm) heart rate measured at discharge. Cox proportional hazard models were employed to explore the association between heart rate and 1-year primary outcome, which was defined as a composite outcome of all-cause death and HF rehospitalization.RESULTS:Among 1760 patients, 723 (41.1%) were women, the median age was 69 (interquartile range [IQR]: 60-77) years, median discharge heart rate was 75 (IQR: 69-84) bpm, and 934 (53.1%) had an LVEF <50%. During 1-year follow-up, a total of 792 (45.0%) individuals died or had at least one HF hospitalization. After adjusting for demographic characteristics, smoking status, medical history, anthropometric characteristics, and medications used at discharge, the groups with low (hazard ratio [HR]: 1.32, 95% confidence interval [CI]: 1.05-1.68, P = 0.020) and high (HR: 1.34, 95% CI: 1.07-1.67, P = 0.009) heart rate were associated with a higher risk of 1-year primary outcome compared with the moderate group. A significant interaction between discharge heart rate and LVEF for the primary outcome was observed (P for interaction was 0.045). Among the patients with LVEF ≥50%, only those with high heart rate were associated with a higher risk of primary outcome compared with the group with moderate heart rate (HR: 1.38, 95% CI: 1.01-1.89, P = 0.046), whereas there was no difference between the groups with low and moderate heart rate. Among the patients with LVEF <50%, only those with low heart rate were associated with a higher risk of primary outcome compared with the group with moderate heart rate (HR: 1.46, 95% CI: 1.09-1.96, P = 0.012), whereas there was no difference between the groups with high and moderate heart rate.CONCLUSIONS:Among the overall HF patients with AF, both low (<65 bpm) and high (≥86 bpm) heart rates were associated with poorer outcomes as compared with moderate (65-85 bpm) heart rate. Among patients with LVEF ≥50%, only a high heart rate was associated with higher risk; while among those with LVEF <50%, only a low heart rate was associated with higher risk as compared with the group with moderate heart rate.TRAIL REGISTRATION:Clinicaltrials.gov; NCT02878811.

Background:Elevated blood pressure (BP) is associated with substantial morbidity and mortality in stroke survivors. China has the highest prevalence of stroke survivors and accounts for one-third of stroke-related deaths worldwide. We aimed to describe the prevalence and treatment of elevated BP across age, sex, and region, and assess the mortality attributable to elevated BP among stroke survivors in China.Materials and methods:Based on 3,820,651 participants aged 35-75 years from all 31 provinces in mainland China recruited from September 2014 to September 2020, we assessed the prevalence and treatment of elevated BP (systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg) among those with self-reported stroke and stratified by age group, sex, and geographic region. We estimated the age- and sex-specific population attributable fractions of death from elevated BP.Results:Among 91,406 stroke survivors, the mean (SD) age was 62 (8) years, and 49.0% were male. The median interquartile range (IQR) stroke duration was 4 (2, 7) years. The prevalence of elevated BP was 61.3% overall, and increased with age (from 47.5% aged 35-44 years to 64.6% aged 65-75 years). The increment of prevalence was larger in female patients than male patients. Elevated BP was more prevalent in northeast (66.8%) and less in south (54.3%) China. Treatment rate among patients with elevated BP was 38.1%, and rates were low across all age groups, sexes, and regions. Elevated BP accounted for 33 and 21% of cardiovascular and all-cause mortality among stroke survivors, respectively. The proportion exceeded 50% for cardiovascular mortality among patients aged 35-54 years.Conclusion:In this nationwide cohort of stroke survivors from China, elevated BP and its non-treatment were highly prevalent across all age groups, sexes, and regions. Elevated BP accounted for nearly one-third cardiovascular mortality in stroke survivors, and particularly higher in young and middle-aged patients. National strategies targeting elevated BP are warranted to address the high stroke burden in China.
