Background: Whereas observational cohort data suggest the association between HDL-C and coronary heart disease (CHD) is inverse and linear, data are sparse at HDL-C values > 80mg/dL. Methods: We therefore pooled data from the NHLBI public-funded datasets of the Framingham, Framingham Offspring, and Atherosclerosis Risk in Communities studies. We used multivariable Cox Proportional-Hazards Models to adjust for age, systolic blood pressure, body mass index, smoking status, prevalent diabetes, non-HDL-C, antihypertension and lipid medication use. We calculated adjusted hazard ratios (HR) to assess the association between a priori strata of HDL-C (<30; >30-40; >40-50; >50-60; >60-70; >70-80; >80mg/dL) and CHD death and non-fatal myocardial infarction using HDL-C >40-50mg/dL as the referent. Results: Over 118,716 person*years of follow up, there were 562 events in 9,226 participants. As expected, hazard ratios for CHD events are greatest in the lowest category of HDL-C (HR 1.68, 95%CI: 1.31, 2.21) and there was generally a stepwise inverse trend in CHD hazards up to 80mg/dL. (See Figure) At HDL-C > 80mg/dL the hazard point estimate for CHD events was insignificantly higher (HR 0.52, 95% CI 0.29, 0.95) than the hazard observed at HDL-C >70-80mg/dl (HR 0.35, 95% CI 0.18-0.66). However, the hazard for CHD events for HDL-C > 80mg/dL was still significantly lower than the referent. Conclusions: These data suggest that the association between HDL-C and CHD risk may not be inverse and linear at HDL-C values > 80mg/dL. These data support investigation into qualitative differences in HDL molecules in individuals with very high levels of HDL-C.

Objective: To our knowledge, no studies have yet looked at how the risk of developing breast cancer (BC) varies with changes in metabolic syndrome (MetS) status. This study aimed to investigate the association between changes in MetS and subsequent BC occurrence. Research Design and Methods: We enrolled 930,055 postmenopausal women aged 40–74 years who participated in a biennial National Health Screening Program in 2009–2010 and 2011–2012. Participants were categorized into four groups according to change in MetS status during the two-year interval screening: sustained non-MetS, transition to MetS, transition to non-MetS, and sustained MetS. We calculated multivariable-adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for BC incidence using the Cox proportional hazards models. Results: At baseline, MetS was associated with a significantly increased risk of BC (aHR 1.11, 95% CI 1.06–1.17) and so were all of its components. The risk of BC increased as the number of the components increased (aHR 1.46, 95% CI 1.26–1.61 for women with all five components). Compared to the sustained non-MetS group, the aHR (95% CI) for BC was 1.11 (1.04–1.19) in the transition to MetS group, 1.05 (0.96–1.14) in the transition to non-MetS group, and 1.18 (1.12–1.25) in the sustained MetS group. Conclusions: Significantly increased BC risk was observed in the sustained MetS and transition to MetS groups. These findings are clinically meaningful in that efforts to recover from MetS may lead to reduced risk of BC.

Abstract Purpose The neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation that has been reported to be associated with survival after chronic disease diagnoses, including lung cancer. We hypothesized that the inflammatory profile reflected by pre-diagnosis NLR, rather than the well-studied pre-treatment NLR at diagnosis, may be associated with increased mortality after lung cancer is diagnosed in high-risk heavy smokers. Methods We examined associations between pre-diagnosis methylation-derived NLR (mdNLR) and lung cancer-specific and all-cause mortality in 279 non-small lung cancer (NSCLC) and 81 small cell lung cancer (SCLC) cases from the β-Carotene and Retinol Efficacy Trial (CARET). Cox proportional hazards models were adjusted for age, sex, smoking status, pack years, and time between blood draw and diagnosis, and stratified by stage of disease. Models were run separately by histotype. Results Among SCLC cases, those with pre-diagnosis mdNLR in the highest quartile had 2.5-fold increased mortality compared to those in the lowest quartile. For each unit increase in pre-diagnosis mdNLR, we observed 22–23% increased mortality (SCLC-specific hazard ratio [HR] = 1.23, 95% confidence interval [CI]: 1.02, 1.48; all-cause HR = 1.22, 95% CI 1.01, 1.46). SCLC associations were strongest for current smokers at blood draw (Interaction Ps = 0.03). Increasing mdNLR was not associated with mortality among NSCLC overall, nor within adenocarcinoma (N = 148) or squamous cell carcinoma (N = 115) case groups. Conclusion Our findings suggest that increased mdNLR, representing a systemic inflammatory profile on average 4.5 years before a SCLC diagnosis, may be associated with mortality in heavy smokers who go on to develop SCLC but not NSCLC.

Abstract Background Theoretical concern exists regarding AV block (AVB) with class I antiarrhythmics (AADs) when bundle branch block (BBB) is present. Whether this is substantiated in real-world populations is unknown. Purpose To determine the relationship between type of AAD and incidence of AVB in patients with preexisting BBB. Methods We retrospectively studied all patients with BBB who received class I and III AADs between 1997–2019 to compare incidence of AVB. We defined index time as first exposure to either drug class and excluded patients with prior AVB or exposed to both classes. Time-at-risk window ended at first outcome occurrence or when patients were no longer observed in the database. We estimated hazard ratios for incident AVB using Cox proportional hazards models with propensity score stratification, adjusting for over 32,000 covariates from the electronic health record. Kaplan-Meier methods were used to determine treatment effects over time. Results Of 40,120 individuals with BBB, 148 were exposed to a class I AAD and 2401 to a class III AAD. Over nearly 4,200 person-years of follow up, there were 22 and 620 outcome events in the class I and class III cohorts, respectively (Figure). In adjusted analyses, AVB risk was markedly lower in patients exposed to class I AADs compared with class III (HR 0.48 [95% CI 0.30–0.75]). Conclusion Among patients with BBB, exposure to class III AADs was strongly associated with greater risk of incident AVB. This likely reflects differences in natural history of patients receiving class I vs class III AADs rather than adverse class III effects, however, the lack of worse outcomes acutely with class I AADs suggests that they may be safer in BBB than suspected.

Purpose To examine the effect of age on the recurrence of soft tissue sarcoma in the extremities and trunk. Patients and Methods This was a multicenter study that included 2,385 patients with median age at surgery of 57 years. The end points considered were local recurrence and metastasis. Cox proportional hazards models were used to estimate hazard ratios across the age ranges with and without adjustment for known confounding factors. Results Older patients presented with tumors that were larger (P < .001) and of higher grade (P < .001). The proportion of positive margins increased significantly as patients age (P < .001), but radiation therapy was relatively underused in patients older than age 60 years. The 5-year cumulative incidences of local recurrence were 7.2% (95% CI, 4% to 11.7%) for patients age 30 years or younger and 12.9% (95% CI, 9.1% to 17.5%) for patients age 75 years or older. The corresponding 5-year cumulative incidences of metastasis were 17.5% (95% CI, 12.1% to 23.7%) and 33.9% (95% CI, 28.1% to 39.8%) for the same groups. Regression models showed that age was significantly associated with local recurrence (P < .001) and metastasis (P < .001) in nonadjusted models. After adjusting for imbalance in presentation and treatment variables, age remained significantly associated with local recurrence (P = .031) and metastasis (P = .019). Conclusion Older patients have worse outcomes because they tend to present with worse tumors and are treated less aggressively. However, there remained a significant increase in the risk of both local and systemic recurrence associated with increasing age that could not be explained by tumor or treatment characteristics.

Objective: The independent prognostic value of prehypertension (preHTN) for incident coronary heart disease (CHD) remains unsettled. Using the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort study, we examined associations between preHTN and incident acute CHD and CVD death. Methods: REGARDS includes 30,239 black and white community-dwelling adults age 45 and older at baseline. Recruitment occurred from 2003-7, with baseline interviews and in-home data collection for physiologic measures. Follow-up is conducted by telephone every 6 months to detect events and deaths, which are adjudicated by experts. Systolic BP was categorized into <120 mmHg (n=4385), 120-129 mmHg (n=4000), 130-139 (n=2066), and hypertension was categorized into controlled (<140/90 mmHg on treatment) (n=8378), and uncontrolled (>140/90 mmHg) (n=5364). Incident acute CHD was defined as definite or probable myocardial infarction (MI) or acute CHD death. CVD death was defined as acute CHD, stroke, heart failure or other cardiovascular disease related. Cox proportional hazards models estimated the hazard ratios (HR) for incident CHD by BP categories, adjusting for sociodemographics and CHD risk factors. Results: The 23,393 participants free of CHD at baseline were followed for a median of 4.4 years. Mean age was 64.1, 58% were women and 42% were black. There was a significant interaction between sex and BP categories, therefore analyses were stratified by sex. There were 252 non-fatal and fatal acute CHD events among women and 407 among men. Among women, compared with SBP<120 mmHg, BP categories above SBP 120 mmHg were associated with incident CHD (adjusted HR for SBP120-129 mmHg=1.94 {95% CI 1.04-3.62]; SBP 130-139 mmHg=1.92 {0.95-3.87}; controlled HTN=2.16 {1.25-3.75}; uncontrolled HTN=3.25 {1.87-5.65}) in fully adjusted models. Among men, only uncontrolled HTN was associated with incident CHD (HR=1.55 {1.11-2.17}). Conclusion: In this sample, preHTN may be associated with incident CHD among women but not men.

The Individual

Background: Some individuals classified as having metabolic syndrome (MetSyn) are centrally obese while others are not with unclear implications for cardiovascular (CV) risk. Methods: REGARDS is following 30,239 individuals ≥45 years of age living in 48 states recruited from 2003-7. MetSyn risk factors were defined using the AHA/NHLBI/IDF harmonized criteria with central obesity being defined as ≥88 cm in women and ≥102 cm in men. Participants with and without central obesity were stratified by whether they met >2 or ≤2 of the other 4 MetSyn criteria, resulting in the creation of 4 groups. To ascertain CV events, participants are telephoned every 6 months with expert adjudication of potential events following national consensus recommendations and based on medical records, death certificates, and interviews with next-of-kin or proxies. Acute coronary heart disease (CHD) was defined as definite or probable myocardial infarction or acute CHD death. To determine the association between these 4 groups and incident acute CHD, we constructed Cox proportional hazards models in those free of CHD at baseline by race/gender group, adjusting for sociodemographic variables. Results: A total of 20,018 individuals with complete data on MetSyn components were free of baseline CHD. Mean age was 64+/−9 years, 58% were women, and 42% were African American. Over a mean follow-up of 3.4 (maximum 5.9) years, there were 442 acute CHD events. In the non-centrally obese with>2 other risk factors, risk for CHD was higher for all but AA men, though significant only for white men. In contrast, in the centrally obese with >2 other risk factors, risk was doubled for women, but only non-significantly and modestly increased for men. Only AA women with central obesity and ≤2 other risk factors had increased CHD risk (Table). Conclusion: The CHD risk associated with the MetSyn varies by the presence of central obesity as well as the race and gender of the individual.

Introduction: Growth differentiation factor 15 (GDF-15) is a marker of oxidative stress and inflammation and has been associated with several cardiovascular disease (CVD) phenotypes. However, conflicting results have been reported regarding the association of GDF-15 with incident atrial fibrillation (AF) in the general population. Hypotheses: Higher GDF-15 level is associated with increased risk of incident AF independent of potential confounders. Methods: In 10,101 White and Black ARIC participants (mean age 60 years and 20.9% Blacks) free of AF at baseline (1993-95), we quantified the association of GDF-15 and incident AF using three Cox proportional hazards models. GDF-15 was measured by SOMA scan assay. AF was defined by hospitalizations with AF diagnosis or death certificates (ICD-9 codes: 427.31-427.32; ICD-10 codes: I48.x) or AF diagnosis by ECG at subsequent ARIC visits. Results: There were 2165 cases of incident AF over a median follow-up of 20.7 years (incidence rate 12.1 cases/1,000 person-years). After adjusting for demographic characteristics and cardiovascular risk factors, log GDF-15 was significantly associated with incident AF (hazard ratio 1.42 (1.25-1.63) for top vs. bottom quartile) (Model 1 in Table ). The result was robust even further adjusting for history of other CVD phenotypes and cardiac markers (Models 2 and 3 in Table ). In Model 3, quartiles of high-sensitive cardiac troponin T (hs-cTnT) did not demonstrate significant associations with incident AF. Conclusions: In community-based population, elevated GDF-15 level was independently and robustly associated with incident AF (even more strongly than troponin). These results suggest the involvement of GDF-15 in the development of AF and the potential of GDF-15 as a risk marker to identify individuals at high risk of AF.

Background and objectivesThe association between plant-based diets, incident CKD, and kidney function decline has not been examined in the general population. We prospectively investigated this relationship in a population-based study, and evaluated if risk varied by different types of plant-based diets.Design, setting, participants, & measurementsAnalyses were conducted in a sample of 14,686 middle-aged adults enrolled in the Atherosclerosis Risk in Communities study. Diets were characterized using four plant-based diet indices. In the overall plant-based diet index, all plant foods were positively scored; in the healthy plant-based diet index, only healthful plant foods were positively scored; in the provegetarian diet, selected plant foods were positively scored. In the less healthy plant-based diet index, only less healthful plant foods were positively scored. All indices negatively scored animal foods. We used Cox proportional hazards models to study the association with incident CKD and linear mixed models to examine decline in eGFR, adjusting for confounders.ResultsDuring a median follow-up of 24 years, 4343 incident CKD cases occurred. Higher adherence to a healthy plant-based diet (HR comparing quintile 5 versus quintile 1 [HRQ5 versus Q1], 0.86; 95% confidence interval [95% CI], 0.78 to 0.96; P for trend =0.001) and a provegetarian diet (HRQ5 versus Q1, 0.90; 95% CI, 0.82 to 0.99; P for trend =0.03) were associated with a lower risk of CKD, whereas higher adherence to a less healthy plant-based diet (HRQ5 versus Q1, 1.11; 95% CI, 1.01 to 1.21; P for trend =0.04) was associated with an elevated risk. Higher adherence to an overall plant-based diet and a healthy plant-based diet was associated with slower eGFR decline. The proportion of CKD attributable to lower adherence to healthy plant-based diets was 4.1% (95% CI, 0.6% to 8.3%).ConclusionsHigher adherence to healthy plant-based diets and a vegetarian diet was associated with favorable kidney disease outcomes.

AbstractObjectiveTo test the association between coffee consumption and risk of all-cause, CVD and cancer death in a European cohort.DesignProspective cohort study. Cox proportional hazards models with adjustment for potential confounders to estimate multivariable hazard ratios (HR) and 95 % CI were used.SettingCzech Republic, Russia and Poland.SubjectsA total of 28561 individuals followed for 6·1 years.ResultsA total of 2121 deaths (43·1 % CVD and 35·7 % cancer mortality) occurred during the follow-up. Consumption of 3–4 cups coffee/d was associated with lower mortality risk in men (HR=0·83; 95 % CI 0·71, 0·99) and women (HR=0·63; 95 % CI 0·47, 0·84), while further intake showed non-significant reduced risk estimates (HR=0·71; 95 % CI 0·49, 1·04 and HR=0·51; 95 % CI 0·24, 1·10 in men and women, respectively). Decreased risk of CVD mortality was also found in men (HR=0·71; 95 % CI 0·54, 0·93) for consumption of 3–4 cups coffee/d. Stratified analysis revealed that consumption of a similar amount of coffee was associated with decreased risk of all-cause (HR=0·61; 95 % CI 0·43, 0·87) and cancer mortality (HR=0·59; 95 % CI 0·35, 0·99) in non-smoking women and decreased risk of all-cause mortality for >4 cups coffee/d in men with no/moderate alcohol intake.ConclusionsCoffee consumption was associated with decreased risk of mortality. The protective effect was even stronger when stratification by smoking status and alcohol intake was performed.
