Increased awareness, inadequate treatment, and poor control of cardiovascular risk factors in American young adults: 2005-2016.

INTRODUCTION: There are little contemporary data about cardiovascular risk factors among young adults. We defined trends in diabetes mellitus (DM), hypertension, and hypercholesterolemia in American adults aged 18-44 years. METHODS: The National Health and Nutrition Examination Study serial cross-sectional surveys were used to define three time periods: 2005-2008, 2009-2012, and 2013-2016. Age-adjusted weighted trends of prevalence, awareness, treatment, and control of DM, hypertension, and hypercholesterolemia were calculated by linear regression modelling in the overall sample, males, and females. Trends were calculated after adjustment for age, race, body mass index, smoking status, education attainment, income, insurance status, and number of healthcare visits. RESULTS: From 2005-2008 to 2013-2016, 15,171 participants were identified. DM prevalence was stable ∼3%, hypertension prevalence was stable ∼11.0%, and hypercholesterolemia prevalence declined from 11.5% to 9.0% (ptrend = 0.02). DM awareness stayed stable between 61.1 and 74.1%, hypertension awareness increased from 68.7 to 77.7% (ptrend = 0.05), and hypercholesterolemia awareness was stable between 46.8 and 54.1%. DM and hypertension treatment improved markedly (ptrend < 0.001 and 0.05, respectively) but the hypercholesterolemia treatment was stable ∼30%. DM control improved across survey periods (7.7-17.4%, ptrend = 0.04) but hypertension control (∼50%) and hypercholesterolemia control (∼13%) remained stable. Prevalence, awareness, treatment, and control trends also differed between males and females. CONCLUSIONS: There is a stable prevalence of DM, high and stable prevalence of hypertension, and declining prevalence of hypercholesterolemia among young Americans. Despite stable or increasing awareness of diabetes and hypertension, there are inadequate treatment and control trends for DM, hypertension, and hypercholesterolemia.

Clinical, Demographic, and Imaging Correlates of Anemia in Heart Failure With Preserved Ejection Fraction (from the RELAX Trial).

Anemia is a commonly occurring comorbidity among patients of heart failure with preserved ejection fraction (HFpEF) but limited data exists on the cardiovascular phenotype of anemia in HFpEF. We sought to characterize the clinical features, exercise capacity, and outcomes in patients with HFpEF to elucidate the phenotype and pathophysiology of anemia in HFpEF. Post hoc analyses of participants enrolled in the RELAX (Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in Diastolic Heart Failure) trial was performed. Anemia was defined as hemoglobin <13 g/dL in men and <12 g/dL in women. Multivariate adjusted regression modeling was done to assess for differences in peak oxygen uptake. Adjusted hazard ratios were generated to assess difference in hospitalization events using a Cox proportional hazards model. Anemic HFpEF patients were more likely to be older, male, and have worse renal function (p <0.05 for all). N-terminal pro-B-type natriuretic peptide, troponin I, pro-collagen III N-terminal peptide, C-telopeptide for type I collagen, uric acid, cystatin-c, and galectin-3 (p <0.05 for all) levels were higher in anemic HFpEF patients. In adjusted models, anemic HFpEF patients had worse exercise capacity (peak oxygen uptake: 11.3 vs 12.1 mL/kg/min; p = 0.004). The hazard for cardiac or renal cause of hospitalization in those with anemia was 2.0 (95% confidence interval: 0.9 to 4.3). Anemic HFpEF patients have worse exercise capacity and are more likely to be hospitalized. A better understanding of the physiologic phenotypes of HFpEF patients may allow for greater personalization of treatment and prognostication in HFpEF patients.

Implications of Atrial Fibrillation Among Patients With Atherosclerotic Cardiovascular Disease Undergoing Noncardiac Surgery.

Atrial fibrillation (AF) is a common perioperative arrhythmia. However, its occurrence and implications remain poorly defined in the setting of noncardiac procedures. We sought to define the incidence, prevalence, and prognostic implications of AF among patients with atherosclerotic cardiovascular disease (ASCVD) undergoing noncardiac surgery. Using a previously validated approach that employed unique patient-linked variables in the New York State Inpatient Database from January 1, 2012, to December 31, 2014, the frequency of new-onset and pre-existing AF was determined in adults with ASCVD aged ≥18 years undergoing noncardiac surgery. The secondary outcomes were stroke within 1 month and all-cause mortality. Using multivariable logistic regression models, the factors and outcomes associated with new-onset AF after noncardiac surgery were assessed. Nine surgical subgroups of major noncardiac surgery served as exposure. A total of 184,775 patients were identified during the study period. Age ≥65, anemia, history of heart failure, valvular heart disease, and thoracic surgery were predictors of new-onset AF after noncardiac surgery. Among 3,806 patients (2.5%) developed new-onset AF and 31,603 (17.5%) patient had pre-existing AF. After multivariable-adjusted modeling, new-onset AF was associated with increased odds of stroke within 1 month (odds ratio: 1.31, 95% confidence interval: 1.12 to 1.53; p < 0.001)], mortality (odds ratio: 3.74; 95% confidence interval: 3.30 to 4.24; p < 0.001) and longer length of stay in the hospital (10 days; interquartile range: 6 to 16 days; p < 0.001). New-onset AF portends a poor prognosis in patients with ASCVD undergoing noncardiac surgeries. The risk profile of patients that develop new-onset AF differs across patient phenotypes and by surgical procedure.

Ideal Cardiovascular Health Among American Adults After the Economic Recession of 2008-2009: Insights from NHANES.

BACKGROUND: The economic recession of 2008-2009 resulted in unprecedented employment and economic losses leading to deterioration of cardiovascular health. We examined the trends in ideal cardiovascular health as measured by the American Heart Association's (AHA's) Life's Simple 7 metric during the periods of economic recession and subsequent economic recovery. METHODS: Data on adults ages ≥20 years from the NHANES from economic-recession (2007-2010) and post-recession (2011-2016) periods was analyzed. The AHA's Life's Simple 7 score of 10-14 was used to classify ideal cardiovascular health status. Socioeconomic status was divided into 3 categories: high, middle, and low based on education and income status. Multivariable linear and logistic regression models including demographics, insurance status, health care access, and adjustment for multiple testing were used to analyze the trends in prevalence of ideal cardiovascular health across socioeconomic strata. RESULTS: We observed a decline in the multivariable-adjusted mean cardiovascular health score from 8.18 in 2007-2010 to 7.94 in 2015-2016 (Plinear = 0.02). This was primarily driven by the increasing prevalence of obesity (34% in 2007-2010 vs 41% in 2015-2016, Plinear = 0.005) and poor fasting glucose (8% in 2007-2010 vs 12% in 2015-2016, Plinear = 0.003). In multivariable-adjusted models, we observed the decreasing prevalence of ideal cardiovascular health with a nonlinear trend in the participants in the highest (51% in 2007-2010 vs 42% in 2015-2016, Pquadratic = 0.01) and lowest socioeconomic strata (16% in 2007-2010 vs 13% in 2015-2016, Pquadratic = 0.02). The prevalence of ideal cardiovascular health was higher in participants with high-socioeconomic status compared with other socioeconomic status participants. CONCLUSIONS: Despite economic recovery, ideal cardiovascular health metrics have not yet recovered. Cardiovascular health appears to be further deteriorating for US adults, particularly those in high- and lower-socioeconomic strata.
