Background: The elevated blood pressure (BP) at midlife or late-life is associated with cardiovascular disease and death. However, there is limited research on the association between the BP patterns from middle to old age and incident coronary heart disease (CHD) and death.Methods: A cohort of the Atherosclerosis Risk in Communities (ARIC) Study enrolled 9,829 participants who attended five in-person visits from 1987 to 2013. We determined the association of mid- to late-life BP patterns with incident CHD and all-cause mortality using multivariable-adjusted Cox proportional hazards models.Results: During a median of 16.7 years of follow-up, 3,134 deaths and 1,060 CHD events occurred. Compared with participants with midlife normotension, the adjusted hazard ratio for all-cause mortality and CHD was 1.14 (95% CI, 1.04–1.25) and 1.28 (95% CI, 1.10–1.50) in those with midlife hypertension, respectively. In further analyses, compared with a pattern of sustained normotension from mid- to late-life, there was no significant difference for the risk of incident death (HR, 1.15; 95% CI, 0.96–1.37) and CHD (HR, 1.33; 95% CI, 0.99–1.80) in participants with a pattern of midlife normotension and late-life hypertension with effective BP control. A higher risks of death and CHD were found in those with pattern of mid- to late-life hypertension with effective BP control (all-cause mortality: HR, 1.24; 95% CI, 1.08–1.43; CHD: HR, 1.65; 95% CI 1.30–2.09), pattern of midlife normotension and late-life hypertension with poor BP control (all-cause mortality: HR, 1.27; 95% CI, 1.12–1.44; CHD: HR, 1.53; 95% CI, 1.23–1.92), and pattern of mid- to late-life hypertension with poor BP control (all-cause mortality: HR, 1.49; 95% CI, 1.30–1.71; CHD: HR, 1.87; 95% CI, 1.48–2.37).Conclusions: The current findings underscore that the management of elderly hypertensive patients should not merely focus on the current BP status, but the middle-aged BP status. To achieve optimal reductions in the risk of CHD and death, it may be necessary to prevent, diagnose, and manage of hypertension throughout middle age.

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.

Introduction: Ultra-processed food defined as food and drink products formulated through sequences of industrial processes, and generally contain non-culinary used additives. Previous studies have linked higher ultra-processed food intake with several cardiometabolic and cardiovascular diseases. However, longitudinal evidence from US populations remains scarce. Hypothesis: We hypothesized that higher intake of ultra-processed food is associated with higher risk of coronary heart disease (CHD). Methods: We selected 12,607 adults aged 44-66 years in 4 US communities from the ARIC study at baseline. Dietary intake data were collected through a validated 66-item food frequency questionnaire. Ultra-processed foods were defined using the NOVA classification and the level of intake was calculated for each participant. We conducted Cox proportional hazards models to study the association between quartiles of ultra-processed food intake and incident CHD. Nonlinearity was assessed by using restricted cubic spline regression. Results: There were 1,899 incident CHD cases documented after an median follow up of 27 years (291,285.2 person-years). Incidence rates were higher in the highest quartile of ultra-processed food intake (71.6 per 10,000 person-years; 95% CI, 65.8-78.0) compared to the lowest quartile (59.7 per 10,000 person-years; 95% CI, 54.3-65.7). Participants in the highest vs. lowest quartile were associated with a 18% higher risk of CHD (Hazard ratio 1.18 [95% CI, 1.04 - 1.34]; P-trend = 0.010) after adjusting for sociodemographic factors and health behaviors. An approximately linear relationship was observed between ultra-processed food intake and risk of CHD after 4 servings/day ( Figure ). Conclusion: In conclusion, higher ultra-processed food intake was associated with a higher risk of coronary heart disease among middle-aged US adults. Further prospective studies are needed to confirm these findings and to investigate the mechanisms by which ultra-processed food may affect health.

Background: HbA1c is the standard measure to monitor glucose control and is now used for diagnosis of diabetes. Fructosamine and glycated albumin are markers of short-term glycemic control that may add complementary information to HbA1c. However, the associations of fructosamine and glycated albumin with cardiovascular outcomes are uncharacterized. Methods: We measured glycated albumin and fructosamine in 11104 adult participants (792 with a history of diabetes) of the community-based ARIC Study without cardiovascular disease at baseline (1990-1992). We evaluated the associations of fructosamine and glycated albumin with incident coronary heart disease and total mortality. We compared these associations to those for HbA1c. Results: Baseline HbA1c was highly correlated with fructosamine (Pearson’s r =0.82) and glycated albumin (Pearson’s r=0.86). During over two decades of follow-up there were 1,032 new cases of coronary heart disease and 2,594 deaths. In Cox proportional hazards models adjusted for traditional cardiovascular risk factors, elevated baseline levels of fructosamine and glycated albumin were significantly associated with coronary heart disease and total mortality ( Figure ). After additional adjustment for HbA1c, the associations were attenuated but remained significant, particularly at diabetic levels of fructosamine and glycated albumin. The associations with death were J-shaped, with an elevation of risk also apparent at the lowest levels of each biomarker, as has been previously observed for HbA1c. Conclusions: The acceptance of new measures of hyperglycemia is partly dependent on establishing their association with long-term outcomes. We found that fructosamine and glycated albumin were associated with coronary heart disease and mortality and that these associations were similar to those observed for HbA1c. The elevated risk of death at very low levels of fructosamine, glycated albumin, and HbA1c deserves further examination.

Abstract Aims We estimated the association between outdoor light at night at the residence and risk of coronary heart disease (CHD) within a prospective cohort of older adults in Hong Kong. Methods and results Over a median of 11 years of follow-up, we identified 3772 incident CHD hospitalizations and 1695 CHD deaths. Annual levels of outdoor light at night at participants’ residential addresses were estimated using time-varying satellite data for a composite of persistent night-time illumination at ∼1 km2 scale. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of the association between outdoor light at night at the residence and risk of CHD. The association between light at night and incident CHD hospitalization and mortality exhibited a monotonic exposure-response function. An interquartile range (IQR) (60.0 nW/cm2/sr) increase in outdoor light at night was associated with an HR of 1.11 (95% CI: 1.03, 1.18) for CHD hospitalizations and 1.10 (95% CI: 1.00, 1.22) for CHD deaths after adjusting for both individual and area-level risk factors. The association did not vary across strata of hypothesized risk factors. Conclusion Among older adults, outdoor light at night at the residence was associated with a higher risk of CHD hospitalizations and deaths. We caution against causal interpretation of these novel findings. Future studies with more detailed information on exposure, individual adaptive behaviours, and potential mediators are warranted to further examine the relationship between light at night and CHD risk.

Background. There are no proven effective treatments that can reduce the mortality in heart failure with preserved ejection fraction (HFpEF), probably due to its heterogeneous nature which will weaken the effect of therapy in clinical studies. We evaluated the effect of beta-blocker treatment in HFpEF patients associated with atrial fibrillation (AF), which is a homogeneous syndrome and has seldom been discussed. Methods. This retrospective cohort study screened 955 patients diagnosed with AF and HFpEF. Patients with a range of underlying heart diseases or severe comorbidities were excluded; 191 patients were included and classified as with or without beta-blocker treatment at baseline. The primary outcome was all-cause mortality and rehospitalization due to heart failure. Kaplan-Meier curves and multivariable Cox proportional-hazards models were used to evaluate the differences in outcomes. Results. The mean follow-up was 49 months. After adjustment for multiple clinical risk factors and biomarkers for prognosis in heart failure, patients with beta-blocker treatment were associated with significantly lower all-cause mortality (hazard ratio (HR) = 0.405, 95% confidence interval (CI) = 0.233–0.701, p=0.001) compared with those without beta-blocker treatment. However, the risk of rehospitalization due to heart failure was increased in the beta-blocker treatment group (HR = 1.740, 95% CI = 1.085–2.789, p=0.022). There was no significant difference in all-cause rehospitalization between the two groups (HR = 1.137, 95% CI = 0.803–1.610, p=0.470). Conclusions. In HFpEF patients associated with AF, beta-blocker treatment is associated with significantly lower all-cause mortality, but it increased the risk of rehospitalization due to heart failure.

Abstract Background We aimed to determine whether Plasmodium falciparum (Pf) infection affects age of Kaposi sarcoma-associated herpesvirus (KSHV) seroconversion in Kenyan children. Methods Kenyan children (n=144) enrolled at age one month, from two sites with different levels of malaria transmission (stable/high malaria vs. unstable/low malaria transmission) were followed through 24 months. Plasma was tested for KSHV antibodies using enzyme-linked immunosorbent assay (ELISA) (K8.1 and LANA) and a multiplex bead-based assay (K8.1, K10.5, ORF38, ORF50, and LANA) and whole blood tested for Pf DNA using quantitative-PCR. Cox proportional hazards models were used to assess associations between Pf DNA detection, malaria annualized rate (Pf detections/person-years), and enrollment site (malaria-high vs malaria-low) with time to KSHV seroconversion. Results KSHV seroprevalence was 63% by 2 years of age when assessed by multiplex assay. Children with Pf were at increased hazards of earlier KSHV seroconversion and among children with malaria, the hazard of becoming KSHV seropositive increased significantly with increasing malaria annualized rate. Children from the malaria-high transmission region had no significant difference in hazards of KSHV seroconversion at 12 months but were more likely to become KSHV seropositive by 24 months of age. Discussion Malaria exposure increases the risk for KSHV seroconversion early in life.

Atherosclerosis Risk

Introduction: Rates of cerebrovascular disease, heart failure (HF), and coronary heart disease (CHD), increase progressively as blood pressure rises. Several authors have estimated the theoretical effects of shifting the population distribution of blood pressure; however few studies have examined the degree to which modest decrements in blood pressure affect HF incidence, or included a racially diverse population. Methods: Incident HF was identified by a first hospitalization with discharge diagnosis code of 428.X. Incident hospitalized (definite or probable) CHD and stroke were classified according to protocol. We used multivariable regression to estimate incidence rate differences (IRD) for HF, CHD, and stroke that could be associated with a two mm Hg reduction in systolic blood pressure (SBP) in 15,744 participants from the Atherosclerosis Risk in Communities Study. Results: Over a mean of 18.3 years of follow up, age-adjusted incidence rates for HF, CHD, and stroke were higher among African American than Caucasians (Table 1). After adjusting for antihypertensive use, gender, and age, a two mm Hg decrement in SBP across the total population was associated with an estimated 24/100,000 person-years (PY) and 39/100,000 PY fewer incident HF events in Caucasians and African Americans, respectively. The projected disease reductions were of smaller absolute magnitude for incident CHD and incident stroke. Extrapolation to the African American and Caucasian U.S. populations age greater than 45 years suggests that a two mmHg decrement in SBP could result in approximately 22,000 fewer incident HF events, 15,000 fewer incident CHD events, and 5,000 fewer incident stroke events annually. Conclusion: Our results suggest that modest shifts in SBP, consistent with what could theoretically be achieved through population level lifestyle interventions, could substantially decrease the incidence of HF, stroke, and CHD in the United States, especially among African American populations.

Background: Increased attention has been given to pulse pressure (PP) as a potential independent risk factor of cardiovascular disease. We examined the relationship between PP and incident acute coronary heart disease (CHD). Methods: We used data from the REasons for Geographic And Racial Differences in Stroke (REGARDS) national cohort study of 30,239 black and white participants aged 45 years or older and enrolled between 2003 and 2007. Baseline data included a 45-minute interview and in-home visit during which blood pressure was assessed and recorded as the average of two measurements obtained after a 5 minute seated rest. PP (SBP-DBP) was classified into 4 groups (<45, 45-54, 54.1-64, >64.1 mmHg). Telephone follow-up occurred every six months for self or proxy-reported suspected events, triggering medical record retrieval and adjudication by experts. Cox-proportional hazards models examined the association of incident CHD with PP groups, adjusting for socio-demographic and clinical risk factors. Results: This analysis included 22,909 participants free of CHD at baseline, with mean age 64.7±9.4 years; 40.4%were black, 44.6% were male and they experienced a total of 515 incident CHD events over a mean 3.4 yrs of follow-up (maximum 6 years). In unadjusted analyses, compared with PP<45 mmHg, each higher PP group had incrementally higher hazard ratios (HR) for incident CHD (HR 1.28 {95% CI 1.02-1.60}, 2.05 {1.63-2.56}, 3.82 {3.08-4.74}, p<0.001 for linear trend). This relationship persisted after fully adjusting including SBP for the highest PP group (HR 0.96 {0.75-1.21}, 1.12 {0.86-1.46}, 1.51 {1.09-2.10}, p trend <0.0001). Conclusions: High PP was associated with incident CHD, even when accounting for SBP and numerous other CVD risk factors.
