Atherosclerosis Risk

Background Black individuals have a higher burden of risk factors for heart failure (HF) and subclinical left ventricular remodeling. Methods and Results We evaluated 1871 Black participants in the Atherosclerosis Risk in Communities Study cohort who attended a routine examination (1993–1996, median age 58 years) when they underwent echocardiography. We estimated the prevalences of 4 HF stages: (1) Stage 0 : no risk factors; (2) Stage A : presence of HF risk factors (hypertension, diabetes mellitus, obesity, smoking, dyslipidemia, coronary artery disease without clinical myocardial infarction), no cardiac structural/functional abnormality; (3) Stage B : presence of prior myocardial infarction, systolic dysfunction, left ventricular hypertrophy, regional wall motion abnormality, or left ventricular enlargement; and (4) Stage C/D : prevalent HF. We assessed the incidence of clinical HF, atherosclerotic cardiovascular disease events, and all‐cause mortality on follow‐up according to HF stage. The prevalence of HF Stages 0, A, B, and C/D were 3.8%, 20.6%, 67.0%, and 8.6%, respectively, at baseline. On follow‐up (median 19.0 years), 309 participants developed overt HF, 390 incurred new‐onset cardiovascular disease events, and 651 individuals died. Incidence rates per 1000 person‐years for overt HF, cardiovascular disease events, and death, respectively, were Stage 0, 2.4, 0.8, and 7.6; Stage A, 7.4, 9.7, and 13.5; Stage B 13.6, 15.9, and 22.0. Stage B HF was associated with a 1.5‐ to 2‐fold increased adjusted risk of HF, cardiovascular disease events and death compared with Stages 0/A. Conclusions In our large community‐based sample of Black individuals, we observed a strikingly high prevalence of Stage B HF in middle age that was a marker of high cardiovascular morbidity and mortality.

Introduction: Apparent resistant hypertension (ARH) is a common marker of risk in patients with established cardiovascular disease. We ascertained the prevalence and prognostic significance of ARH in patients without prior cardiovascular disease. Methods: This prospective observational cohort study included 9669 community-based participants without a history of heart failure, myocardial infarction, or stroke, who completed the Atherosclerosis Risk in Communities (ARIC) study visit 4 between 1996-1998. The definition of ARH was blood pressure (BP) above goal (traditional goal <140/90mmHg, more stringent goal <130/80mmHg) despite use of ≥3 antihypertensive drug classes, or any BP with ≥4 antihypertensive drug classes. Participants with controlled hypertension (CH), defined as BP at goal with use of 1-3 antihypertensive drug classes, constituted the reference group. The outcome was a composite endpoint of heart failure, myocardial infarction, stroke, or death. Cox regression models were adjusted for age, sex, race, BMI, heart rate, smoking, eGFR, LDL, HDL, triglycerides, glucose, and diabetes. Results: Applying the traditional BP goal, 154/9669 participants (1.6%) had ARH, and there were 2311 participants with CH (23.9%). Using the more stringent BP goal, 218/9669 participants (2.3%) had ARH, and 1523 participants (15.8 %) had CH. The median follow-up time was 19 years. Apparent resistant hypertension was associated with an increased risk for the composite endpoint (adjusted hazard ratio 1.58 [95% CI 1.32-1.90] with the traditional BP goal, and adjusted hazard ratio 1.51 [95% CI 1.28-1.79] with the more stringent BP goal). Conclusions: Apparent resistant hypertension had a low prevalence but was independently associated with adverse outcome during long term follow-up, compared to controlled hypertension and even compared to uncontrolled hypertension. This was observed for both traditional and more stringent BP goals.

Background: Heart failure (HF) affects a large number of Americans with an estimated lifetime risk of over 20% among individuals over the age of 40 years. Heart failure is associated with significant morbidity, mortality and health care cost. Epidemiological data suggests that HF disproportionately affects African Americans. Existing risk prediction models may not accurately predict the risk of incident HF in this population limiting the implementation of screening and preventive strategies. We sought to examine the predictors of incident heart failure in a community-based African American cohort. Methods: The study population consisted of 2244 African American participants from the Jackson cohort of the Atherosclerosis Risk in Communities (ARIC) study. Participants with prevalent HF and missing data at the baseline were excluded. Cox proportional regression with backward elimination was used to assess the association of risk markers with first clinical HF event as follows: Model 1 - standard cardiovascular risk factors (age, gender, body mass index [BMI], systolic blood pressure, use of anti-hypertensive medication, diabetes status, current smoking, total cholesterol-HDL ratio [TC:HDL], logarithmically transformed-triglyceride); Model 2 - significant standard risk factors and biomarkers (logarithmically transformed-brain natriuretic peptide [BNP], logarithmically transformed-troponin, logarithmically transformed-albumin-creatinine ratio); Model 3 - significant standard risk factors and subclinical disease markers (estimated glomerular filtration rate [eGFR], ankle-brachial index, forced expiratory volume in one second [FEV1], forced vital capacity, left ventricular ejection fraction < 50%, left ventricular mass indexed to height2.7); Model 4 - significant standard risk factors, significant biomarkers, and significant subclinical disease markers. Results: The mean age and BMI were 58 years and 30 kg/m2 respectively. During a median follow-up of 18.1 years (maximum 19.8), there were 268 incident HF events. Triglyceride from Model 1, Troponin and Albumin-Creatinine ratio from Model 2, and eGFR from Model 3 were eliminated. In the final model, diabetes status (Hazard Ratio [95% Confidence Interval]: 1.76 [1.07, 2.89]), use of anti-hypertensive medication (2.38 [1.40, 4.06]), TC:HDL (1.34 [1.18, 1.52]) and BNP (1.28 [1.14, 1.44]) were significant predictors of incident HF. Higher FEV1 was associated with reduced risk of HF in this study (0.29 [0.11, 0.76]). Conclusion: In this community-dwelling African American population, diabetes status, use of anti-hypertensive medication, TC:HDL ratio, BNP and FEV1 were independent predictors of incident HF. This information may be useful to identify and target high risk individuals for aggressive preventive interventions.

Background The aim is to study common etiological pathways for 3 major cardiovascular diseases (CVD), as reflected in multiple proteins. Methods and Results Eighty‐four proteins were measured using the proximity extension technique in 870 participants in the PIVUS (Prospective Investigation of Uppsala Seniors Study) cohort on 3 occasions (age 70, 75, and 80 years). The sample was followed for incident myocardial infarction, ischemic stroke or heart failure. The same proteins were measured in an independent validation sample, the ULSAM (Uppsala Longitudinal Study of Adult Men) cohort in 595 participants at age 77. During a follow‐up of up to 15 years in PIVUS and 9 years in ULSAM, 222 and 167 individuals experienced a CVD. Examining associations with the 3 outcomes separately in a meta‐analysis of the 2 cohorts, 6 proteins were related to incident myocardial infarction, 25 to heart failure, and 8 proteins to ischemic stroke following adjustment for traditional risk factors. Growth differentiation factor 15 and tumor necrosis factor‐related apoptosis‐inducing ligand receptor 2 were related to all 3 CVDs. Including estimated glomerular filtration rate in the models attenuated some of these relationships. Fifteen proteins were related to a composite of all 3 CVDs using a discovery/validation approach when adjusting for traditional risk factors. A selection of 7 proteins by lasso in PIVUS improved discrimination of incident CVD by 7.3% compared with traditional risk factors in ULSAM. Conclusions We discovered and validated associations of multiple proteins with incident CVD. Only a few proteins were associated with all 3 diseases: myocardial infarction, ischemic stroke, and heart failure.

Background: Chronic kidney disease (CKD) and cardiovascular disease share similar risk factors, such as diabetes, hypertension, and dyslipidemia promoting atherosclerosis. Acute myocardial infarction (MI) presenting without chest pain is associated with higher case fatality compared to MI with chest pain. Patients with non-ST-elevation MI (NSTEMI) are more likely to present without chest pain than patients with ST-elevation MI (STEMI). Few if any studies have examined the risk of incident CKD following MI with and without chest pain. Hypothesis: We hypothesized that MI presenting without chest pain is associated with greater risk of incident CKD after adjustment for demographic factors, in-hospital complications, and comorbidities among adults in the Atherosclerosis Risk in Communities (ARIC) Study. Methods: The ARIC Study is a community-based cohort study that began recruitment in 1987. MI without chest pain includes persons presenting with shortness of breath, nausea, or dyspnea that is determined to be of cardiac origin. Follow-up time for this analysis was calculated from date of MI hospitalization (index date) to incident CKD, death, or administrative censoring in 2017. Incident CKD was defined as eGFR <60 mL/min/1.73 m 2 and ≥25% eGFR decline from previous measurements, CKD-related hospitalization or death, or end-stage renal disease. In-hospital complications included acute heart failure, ventricular fibrillation, and cardiogenic shock. Prevalent CHD and chronic heart failure were measured at visit 1 (1987-1989) and history of diabetes and hypertension were captured from the MI hospitalization record. Results: There was a total of 1,332 MI hospitalizations with data on MI type and symptom presentation. Among 1,038 NSTEMI events, 19% presented without chest pain, compared to 7% of the 294 STEMI events presenting without chest pain. Age greater than 65 years, female gender, and hypertension at the time of the MI as well as in-hospital complications of heart failure and ventricular fibrillation were more common among NSTEMI without chest pain compared to NSTEMI with chest pain. Median follow-up time was 4.9 years (Q1, Q3: 0.9, 11.4 years). Persons with NSTEMI events presenting without chest pain had 1.82 times the risk of incident CKD (95% CI: 1.39, 2.38) compared to NSTEMI events presenting with chest pain. This association was attenuated after adjustment for age at MI, female gender, and black race (HR: 1.36, 95% CI: 1.04, 1.80) and further attenuated after additional adjustment for reperfusion within 24 hours (HR: 1.30, 95% CI: 0.99, 1.72). Conclusion: NSTEMI presenting without chest pain was associated with increased risk of incident CKD, though this association was attenuated after adjustment.

Atherosclerosis Risk

Introduction: Although there is substantial evidence that physical activity reduces risk of cardiovascular disease (CVD), the few studies that included African Americans offer inconclusive evidence and did not study stroke and heart failure separately. Objective: We examined, in African Americans and Caucasians in the Atherosclerosis Risk in Communities study (ARIC), the association of physical activity with CVD incidence (n=1,039) and its major components - stroke (n=350), heart failure (n=633), and coronary heart disease (n=442) - over a follow-up period of 21 years. Methods: ARIC is a population-based biracial cohort study of 45– to 64-yr-old adults at the baseline visit in 1987–89. Physical activity was assessed using the modified Baecke physical activity questionnaire and categorized by the American Heart Association’s ideal CVD health guidelines: poor, intermediate, and ideal physical activity. An incident CVD event was defined as the first occurrence of 1) heart failure, 2) definite or probable stroke, or 3) coronary heart disease, defined as a definite or probable myocardial infarction or definite fatal coronary heart disease. Results: We included 3,707 African Americans and 10,018 Caucasians free of CVD at the baseline visit. After adjustment for age, sex, cigarette smoking, alcohol intake, hormone therapy use, education, and ‘Western’ and ‘Prudent’ dietary pattern scores, higher physical activity was inversely related to CVD, heart failure, and coronary heart disease incidence in African Americans and Caucasians (p-values for trend tests <.0001), and with stroke in African Americans. Hazard ratios (95% confidence intervals) for CVD for intermediate and ideal physical activity, respectively, compared to poor, were similar by race: 0.65 (0.56, 0.75) and 0.59 (0.49, 0.71) for African Americans, and 0.74 (0.66, 0.83) and 0.67 (0.59, 0.75) for Caucasians (p-value for interaction = 0.38). Physical activity was also associated similarly in African Americans and Caucasians for each of the individual CVD outcomes (coronary heart disease, heart failure, and stroke), with an approximate one-third reduction in risk for intermediate and ideal physical activity versus poor physical activity- this reduction was statistically significant. Conclusions: In conclusion, our findings reinforce public health recommendations that regular physical activity is important for CVD risk reduction, including reductions in stroke and heart failure. They provide strong new evidence that this risk reduction applies to African Americans as well as Caucasians and support the idea that some physical activity is better than none.

Background/Aim. Cardiovascular diseases are the leading cause of death in patients treated with hemodialysis (HD). The annual cardiovascular mortality rate in these patients is 9%. Left ventricular (LV) hypertrophy, ischemic heart disease and heart failure are the most prevalent cardiovascular causes of death. The aim of this study was to assess the prevalence of traditional and nontraditional risk factors for cardiovascular complications, to assess the prevalence of cardiovascular complications and overall and cardiovascular mortality rate in patients on HD. Methods. We investigated a total of 115 patients undergoing HD for at least 6 months. First, a cross-sectional study was performed, followed by a two-year follow-up study. Beside standard biochemical parameters, we also determined cardiac troponins and echocardiographic parameters of LV morphology and function (LV mass index, LV fractional shortening, LV ejection fraction). The results were analyzed using the Student's t test and Mann-Whitney U test. Results. The patients with adverse outcome had significantly lower serum albumin (p < 0.01) and higher serum homocystein, troponin I and T, and LV mass index (p < 0.01). Hyperhomocysteinemia, anemia, hypertriglyceridemia and uncontrolled hypertension had the highest prevalence (86.09%, 76.52%, 43.48% and 36.52%, respectively) among all investigated cardiovascular risk factors. Hypertrophy of the LV was presented in 71.31% of the patients and congestive heart failure in 8.70%. Heart valve calcification was found in 48.70% of the patients, pericardial effusion in 25.22% and disrrhythmia in 20.87% of the investigated patients. The average annual overall mortality rate was 13.74%, while average cardiovascular mortality rate was 8.51%. Conclusion. Patients on HD have high risk for cardiovascular morbidity and mortality.

Background . The use of implantable cardiac defibrillators has been associated with improved survival in several well-defined patient (pt) subsets. Its utilization for primary prevention in eligible pts, however, is unclear. We sought to examine the frequency of ICD implantation (ICD-IMP) for primary prevention in a cohort prospectively enrolled in a prospective, multicenter registry of ICD candidates. Methods . We identified 961 pts enrolled in the AdreView Myocardial Imaging for Risk Evaluation in Heart Failure (ADMIRE-HF) study, a prospective, multicenter study evaluating the prognostic usefulness of 123I-mIBG scintigraphy in a heart failure population. Inclusion criteria limited patients to those meeting guideline criteria for ICD implantation; these criteria included left ventricular ejection fraction ≤35% and New York Heart Association functional class II-III. We excluded pts with an ICD at the time of enrollment, leaving a study cohort of 934 patients. Pts were followed up for 24 months after enrollment. Pts undergoing ICD-IMP after enrollment for secondary prevention were censored at the time of intervention. The association between ICD-IMP utilization and demographic, clinical, laboratory, and imaging data was examined using Cox proportional hazards analysis (CPH). Results . Of 934 pts, 196 (21%) were referred for ICD-IMP over a mean follow-up of 612±242 days. Implantations occurred 167±164 days after enrollment. Patients referred for ICD were younger (61±12 vs. 63±12), but did not differ with respect to proportion female (17% vs. 21%), African-American race (12% vs. 15%), diabetics (37% vs. 36%) (All p=NS). The frequency of ICD-IMP did not differ as a function of age, race, sex, LVEF, or imaging result (All p=NS). CPH revealed that a model including age, race, sex, diabetes, smoking, BMI, NYHA class, hypertension, heart failure etiology, and prior MI identified none of these as predictive of ICD-IMP. Conclusion: This analysis of prospective registry data reveals that in patients who are guideline-defined candidates for ICD-IMP, only about one in five receive an ICD over a two year follow-up interval. Multivariable modeling failed to identify any factor associated with ICD use.

Background: Animal experiments in 1970s demonstrated direct cardiotoxicity of long-chain monounsaturated fatty acid (LCMUFA, 22:1 and 24:1 fatty acids) consumption. We recently found plasma phospholipid 22:1 and 24:1 to be associated with 34% and 75% higher risk (quintiles 5 vs. 1), respectively, of congestive heart failure (CHF) among older adults in the Cardiovascular Health Study. We wished to validate these results in a second independent cohort of middle-aged adults. Methods: We evaluated 3,577 adults free of CHF at baseline (age=54.1±5.8) in the Minnesota subcohort of the Atherosclerosis Risk in Communities Study (ARIC) in whom plasma phospholipid LCMUFA were measured. Incident CHF was ascertained from 1988 to 2008 by annual phone contacts, hospitalization discharge codes, and death certificates. Using multivariate Cox models, we evaluated prospective association of each LCMUFA with incident CHF, and potential mediation via CHF risk factors, including ECG left ventricular hypertrophy, and incident coronary heart disease (CHD). As a negative control, we also evaluated incident stroke, given its many shared risk factors for CHF but no link to potentially direct cardiotoxicity. Results: Mean±SD plasma phospholipid levels (% of total fatty acids) of 22:1 and 24:1 were 0.01±0.03 and 0.58±0.17. Over the 64,438 person-years of follow-up, 330 CHF events occurred. After multivariable adjustment, higher levels of 22:1 and 24:1 were associated with higher risk of CHF (Figure). Hazard ratios (95%CI) for quintiles 5 vs. 1 of 22:1 and 24:1 levels were 1.57 (1.11–2.23) and 1.92 (1.22–3.03) (p trend=0.03 and 0.002), respectively. These associations were only partly attenuated by potential mediators, including incident CHD. Neither LCMUFA was associated with incident stroke (not shown). Conclusions: Higher 22:1 and 24:1 LCMUFA levels were associated with CHF risk in middle-aged adults, consistent with our prior findings in older adults. These findings support the possibility of clinical cardiotoxicity of LCMUFA in humans.

Neighborhood Level

Introduction: Atrial fibrillation (AF) is a leading cause of cardiovascular morbidity and mortality. Disparities in AF outcomes have been related to individual-level social determinants of health, including race/ethnicity and socioeconomic status. While neighborhood-level factors, such as poverty, have been related to prevalence of key risk factors (e.g. obesity, hypertension), the association between neighborhood poverty and incident AF has not been previously examined. Methods: Using the Northwestern Medicine Enterprise Data Warehouse, we identified adults free of cardiovascular disease, with at least 5 years of follow-up from January 1, 2005 - December 31, 2013. Residential addresses were geocoded and matched to census tract level poverty estimates from the American Community Survey. Neighborhood poverty was defined as the proportion of residents in the census tract living below the US-defined poverty threshold. We categorized neighborhood poverty levels into tertiles. Generalized linear mixed effects models were used to examine the association between tertiles of neighborhood poverty and incident AF, adjusting for demographic (age, sex, race/ethnicity, insurance type) and AF risk factors (hypertension, diabetes, obesity and smoking status). Results: The cohort comprised 29,069 adults with a mean (SD) age of 51.4 (11.3) years, which included 58% women and 10% non-Hispanic Blacks. Higher rates of obesity, diabetes, hypertension, and smoking were observed in higher poverty groups. Approximately, 3.4% of patients developed incident AF over a follow-up of 5 years. The adjusted odds of incident AF were higher for the medium poverty compared to the low poverty group (adjusted odds ratio, aOR 1.30 (95% CI 1.05-1.56). The aOR of incident AF was similarly higher in the high poverty compared to low poverty group though not statistically significant (Table). Conclusions: In a cohort of adults free of cardiovascular disease at baseline, we found that residence in a more deprived neighborhood was associated with higher rates of incident AF, even after adjustment for traditional risk factors. Understanding how neighborhood and individual-level clinical factors interact to increase the incidence of AF is critical to developing equitable prevention strategies in this increasingly common condition.
