ObjectivesCompared with ST-segment elevation myocardial infarction (STEMI) patients, non-STEMI (NSTEMI) patients have more comorbidities and extensive coronary artery disease. Contemporary comparative data on the long-term prognosis of stable post-myocardial infarction...

Abstract 17225: Association Between Moderate and Vigorous Physical Activity on Long-Term Heart Failure Risk: The Cooper Center Longitudinal Study

Introduction: Regular physical activity (PA) is associated with a lower risk of heart failure (HF). However, the relative contributions of moderate and vigorous intensity exercise on HF risk is still unclear. We characterized the association between moderate (MPA) and vigorous physical activity (VPA) on the long-term risk for HF. Methods: We included participants free from baseline coronary disease in the Cooper Center Longitudinal Study (CCLS) who were Medicare eligible at age 65 years. PA was measured from a self-report instrument that included duration (minutes/week) and intensity of exercise (METs), with moderate intensity as 3-6 METs and vigorous intensity as 6 METs. Incident HF was defined as a HF hospitalization event (primary diagnosis) from Medicare claims files. MPA and VPA were considered separately as continuous variables. The association between baseline PA and incident HF was evaluated by Cox proportional hazards models adjusted for standard HF risk factors. Results: Of 32,322 individuals (mean age 50.9, 74.2% men), the mean number of hours/week of MPA and VPA was 1.2 and 1.4, respectively. 56.42% reported zero MPA and 42.6% reported zero VPA. Higher levels of VPA, but not MPA, were associated with a lower burden of HF risk factors. After 275,373 person-years of follow-up, we observed 954 incident HF hospitalizations. MPA was not significantly associated with HF risk in either model. VPA was inversely associated with HF risk in age-adjusted models. After multivariable adjustment, VPA was not associated with HF risk (see table). Conclusions: Midlife VPA, but not MPA, was associated with a lower risk for HF. However, after additional adjustment for traditional HF risk factors, the association between higher VPA and HF risk was no longer significant. These findings suggest that the inverse association between midlife VPA and long-term HF risk may be mediated by a more favorable risk factor profile.

Menopause, lipids and cardiovascular risk

The greatest mortality burden for women in Europe is due to cardiovascular diseases (CVD), such as stroke and coronary heart disease. Women develop CVD on average 10 years later than men. Premenopausal women have a more favorable CVD risk factor profile characterized by lower cholesterol levels and blood pressure and a lower prevalence of diabetes. During the transition to menopause, women experience changes in phenotype and metabolism associated with an increased risk of CVD; including increase in abdominal fat, increase in low-density lipoprotein-cholesterol (LDLC) and systolic blood pressure, and increased insulin resistance. It has been a matter of debate whether menopause per se is a risk factor of CVD or if it is merely aging.

A Narrative Review on Exercise and Cardiovascular Disease

The favorable risk factor profiles and superb cardiac performance of elite long-distance runners, as well as the anti-aging effects of exercise, have likely contributed to the escalating number of adults worldwide who have embraced the notion that “more exercise is invariably better. Nevertheless, vigorous-to-high-intensity physical activity (PA), particularly when unaccustomed, appears to be a trigger for acute cardiac events in individuals with known or occult atherosclerotic cardiovascular disease or structural cardiovascular abnormalities, most notably, hypertrophic cardiomyopathy. Although regular endurance exercise and moderate-to-vigorous PA provide established cardioprotective benefits, high-volume, high-intensity exercise training regimens appear to induce maladaptive cardiac remodeling in some individuals. These potential adverse cardiac adaptations include accelerated coronary artery calcification (CAC), elevated cardiac biomarker release, myocardial fibrosis, and atrial fibrillation (AF), which may be described by a reverse J-shaped curve. However, the risk for acute cardiovascular events is lower in fit/active persons compared to their unfit/inactive counterparts with the same CAC scores. Similarly, the risk of AF is the highest in habitually sedentary older adults, decreases with light-to-moderate intensity regular PA but increases with high-volume, high-intensity exercise regimens (i.e., reverse J-shaped curve). This review examines these relations and more, with specific reference to the World Health Organization exercise intensity and duration recommendations for optimal health, as well as the thresholds for other research-based exercise metrics, including steps/day and the concept of metabolic equivalents-minutes/week. The primary beneficiaries of exercise training programs and long-term goal training intensities, based on age, sex, and “good fitness, are also discussed. In summary, the benefits of regular moderate-to-vigorous PA and the associated improvements in cardiorespiratory fitness far outweigh the risks for most individuals.

Cardiometabolic Risk Factors and Incident Cardiovascular Disease Events in Women vs Men With Type 1 Diabetes

The lower risk of cardiovascular disease (CVD) among women compared with men in the general population may be diminished among those with diabetes. To evaluate cardiometabolic risk factors and their management in association with CVD events in women vs men with type 1 diabetes enrolled in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study. This cohort study used data obtained during the combined DCCT (randomized clinical trial, conducted 1983-1993) and EDIC (observational study, conducted 1994 to present) studies through April 30, 2018 (mean [SD] follow-up, 28.8 [5.8] years), at 27 clinical centers in the US and Canada. Data analyses were performed between July 2021 and April 2022. During the DCCT phase, patients were randomized to intensive vs conventional diabetes therapy. Cardiometabolic risk factors and CVD events were assessed via detailed medical history and focused physical examinations. Blood and urine samples were assayed centrally. CVD events were adjudicated by a review committee. Linear mixed models and Cox proportional hazards models evaluated sex differences in cardiometabolic risk factors and CVD risk over follow-up. A total of 1441 participants with type 1 diabetes (mean [SD] age at DCCT baseline, 26.8 [7.1] years; 761 [52.8%] men; 1390 [96.5%] non-Hispanic White) were included. Over the duration of the study, compared with men, women had significantly lower body mass index (BMI, calculated as weight in kilograms divided by height in meters squared; β = -0.43 [SE, 0.16]; P = .006), waist circumference (β = -10.56 cm [SE, 0.52 cm]; P < .001), blood pressure (systolic: β = -5.77 mm Hg [SE, 0.35 mm Hg]; P < .001; diastolic: β = -3.23 mm Hg [SE, 0.26 mm Hg]; P < .001), and triglyceride levels (β = -10.10 mg/dL [SE, 1.98 mg/dL]; P < .001); higher HDL cholesterol levels (β = 9.36 mg/dL [SE, 0.57 mg/dL]; P < .001); and similar LDL cholesterol levels (β = -0.76 mg/dL [SE, 1.22 mg/dL]; P = .53). Women, compared with men, achieved recommended targets more frequently for blood pressure (ie, <130/80 mm Hg: 90.0% vs 77.4%; P < .001) and triglycerides (ie, <150 mg/dL: 97.3% vs 90.5%; P < .001). However, sex-specific HDL cholesterol targets (ie, ≥50 mg/dL for women, ≥40 mg/dL for men) were achieved less often (74.3% vs 86.6%; P < .001) and cardioprotective medications were used less frequently in women than men (ie, angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker: 29.6% [95% CI, 25.7%-33.9%] vs 40.0% [95% CI, 36.1%-44.0%]; P = .001; lipid-lowering medication: 25.3% [95% CI, 22.1%-28.7%] vs 39.6% [95% CI, 36.1%-43.2%]; P < .001). Women also had significantly higher pulse rates (mean [SD], 75.2 [6.8] beats per minute vs 71.8 [6.9] beats per minute; P < .001) and hemoglobin A1c levels (mean [SD], 8.3% [1.0%] vs 8.1% [1.0%]; P = .01) and achieved targets for tighter glycemic control less often than men (ie, hemoglobin A1c <7%: 11.2% [95% CI, 9.3%-13.3%] vs 14.0% [95% CI, 12.0%-16.3%]; P = .03). These findings suggest that despite a more favorable cardiometabolic risk factor profile, women with type 1 diabetes did not have a significantly lower CVD event burden than men, suggesting a greater clinical impact of cardiometabolic risk factors in women vs men with diabetes. These findings call for conscientious optimization of the control of CVD risk factors in women with type 1 diabetes.

Risk Factor Profile in Youth, Genetic Risk, and Adulthood Cognitive Function: The Cardiovascular Risk in Young Finns Study

Introduction: The role of risk factor profile in childhood and adolescence on adulthood cognitive function and whether it differs by genetic risk is still obscure. To bring this evidence, we determined cognitive domain-specific youth risk factor profiles leveraging the childhood/adolescence data from the Cardiovascular Risk in Young Finns Study and examined whether genetic propensity for poor cognitive function modifies the association between the risk profiles and adulthood cognitive function. Methods: From 1980, a population-based cohort of 3,596 children (age 3–18 years) has been repeatedly followed up for 31 years. Computerized cognitive test measuring (1) memory and learning, (2) short-term working memory, (3) reaction time, and (4) information processing was performed for 2,026 participants (age 34–49 years). Cognitive domain-specific youth risk profile scores, including physical and environmental factors, were assessed from the data collected at baseline and categorized into favourable, intermediate, and unfavourable. A polygenic risk score for a poor cognitive function was categorized into low, intermediate, and high risk. Results: At all genetic risk levels, a favourable youth risk factor profile is associated with better learning and memory, short-term working memory, and information processing compared to unfavourable risk profile (e.g., β = 0.501 SD, 95% CI: 0.043–0.959 for memory and learning among participants with high genetic risk). However, no significant interactions were observed between the youth risk factor profile score and genetic propensity for any cognitive domain (p > 0.299 for all). Conclusion: A favourable youth risk factor profile may be beneficial for cognitive function in adulthood, irrespective of genetic propensity for poor cognitive function.

Lifestyle behaviors and cardiovascular risk profiles among parous women by gestational diabetes status, 2007–2018

Background and aimsWomen with prior gestational diabetes mellitus (GDM) are at elevated risk of type 2 diabetes mellitus and cardiovascular disease. We compared cardiometabolic risk factors among parous U.S. women ages 20–44 by history of GDM. Methods and resultsUsing data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2018, 3537 parous women were classified by self-reported GDM history. We compared anthropometric measures, glycemia, blood pressure, lipids, lifestyle factors, cardiovascular health, and cardiometabolic disease prevalence by GDM status. NHANES survey design was taken into account. Women without history of GDM were younger and, after adjusting for age, race/ethnicity, and education, had more favorable cardiometabolic risk factor profiles for measures of anthropometry, glycemia, diabetes, many lipids, physical activity, diet, and overall cardiovascular health than women with history of GDM. Many patterns persisted after further adjustment for lifestyle factors. In analyses stratified by race/ethnicity, many patterns persisted, though there were key differences. Hypertension prevalence differed by GDM history only among Hispanic women. In women of other race/ethnicity, there was no difference in healthy eating or body mass index by GDM history. In non-Hispanic Black women, there was no difference in healthy eating by GDM history. ConclusionAmong parous U.S. women ages 20–44, those with history of GDM had less favorable cardiometabolic risk factor profiles than those without history of GDM. This highlights the importance of continued efforts to develop and test multilevel interventions to improve cardiometabolic risk factors among reproductive-age women with a history of GDM.

Marijuana Use and Stress Cardiomyopathy in the Young.

BackgroundIncreased accessibility, recreational use, and regional legalization of marijuana (cannabis) have been paralleled by widespread recognition of its serious cardiovascular complications (acute myocardial infarction, stroke, sudden death) particularly in the young. We aimed to examine trends in hospital admissions and outcomes of adults with stress cardiomyopathy (SC) in temporal relation to marijuana use.Methods and resultsA search of the 2003-2011 Nationwide Inpatient Sample (NIIS) database identified 33,343 admissions for SC of which 210 (0.06%) were temporally related to marijuana use. Demographics, clinical characteristics, and outcomes of marijuana users (MU) and non-marijuana users (NMU) with SC were compared. MU were younger (44±14 vs. 66±13 years), more often male (36% vs. 8%), and had lower prevalence of hypertension (38% vs. 62%), diabetes (2.4% vs. 17.6%), and hyperlipidemia (16% vs. 52%) while more often suffered from depression (33% vs. 15%), psychosis (12% vs. 4%), anxiety disorder (28% vs. 16%), alcohol use disorder (13% vs. 3%), tobacco use (73% vs. 29%), and polysubstance abuse (11% vs. 0.3%) [all p<0.001]. In addition, MU more often suffered a cardiac arrest and required placement of a defibrillator while congestive heart failure was more frequent in NMU. Logistic regression analysis on the entire database (n=71,753,900), adjusted for known risk factors for SC, identified marijuana use as an independent predictor of SC (OR=1.83; 95% CI=1.57-2.12, p<0.0001). Among MU, older age (>48 years) was a strong predictor of any major adverse cardiac event (OR=7.8; 95% CI=2.88-21.13; p<0.0001).ConclusionsMarijuana use is linked to SC in younger individuals and is associated with significant morbidity despite being younger in age and having a more favorable cardiac risk factor profile in affected individuals.

Comparison of cardiovascular disease risk factors, assessment and management in men and women, including consideration of absolute risk: a nationally representative cross-sectional study

ObjectivesCardiovascular disease (CVD) is highly preventable and optimal treatments based on absolute risk can halve risk of future events. Compared with women, men have higher risks of developing CVD. However,...

Cardiac sources of cerebral embolism in people with migraine.

Whether the reported association between migraine with aura (MA) and cardioembolic stroke may be explained by a higher rate of atrial fibrillation (AF) or by other potential cardiac sources of cerebral embolism remains to be determined. In the setting of a single centre cohort study of consecutive patients with acute brain ischaemia stratified by migraine status, the association between AF as well as patent foramen ovale (PFO) and migraine was explored. In all, 1738 patients (1017 [58.5%] men, mean age 67.9±14.9years) qualified for the analysis. Aging was inversely associated with migraine, whilst women had a >3-fold increased disease risk (odds ratio [OR] 3.82, 95% confidence interval [CI] 2.58-5.66). No association between AF and history of migraine or its pathogenic subtypes was detected. Conversely, migraine was associated with PFO, both in the entire cohort (OR 1.84, 95% CI 1.07-3.16) and in patients aged ≤55years (OR 2.21, 95% CI 1.16-4.22). This association was significant for MA (OR 2.92, 95% CI 1.32-6.45 in the entire cohort; OR 2.92, 95% CI 1.15-7.41 in patients aged ≤55years) and in women (OR 8.23, 95% CI 2.06-32.77), but not for migraine without aura. In patients with brain ischaemia migraine is not associated with AF. Conversely, there is a probable relation between migraine, especially MA, and PFO in patients who are younger and have a more favourable vascular risk factor profile, and in women.

Association of Life's Simple 7 with Atrial Fibrillation Burden (From the Atherosclerosis Risk in Communities Study)

The American Heart Association's Life's Simple 7 (LS7) metric consists of 7 modifiable risk factors. Although a more favorable LS7 risk factor profile is associated with lower AF incidence, this relation is unknown in regard to AF burden. We assessed the prospective association of overall LS7 score and individual LS7 risk factors in midlife with AF burden in late-life in the Atherosclerosis Risk in Communities Study. LS7 components were assessed at Visit 3 (1993 to 1995) and a composite score ranging from 0 to 14 was calculated. A higher score indicates better cardiovascular health. AF burden was measured at Visit 6 (2016 to 2017) with a 2-week Zio XT Patch. AF burden, defined as the percent of time a participant was in AF, was categorized as none, intermittent (>0 to <100%), or continuous (100%). Weighted multinomial logistic regression was used. Of the 2,363 participants, 58% were female and 24% were black. Participants were aged 57 ± 5 years at Visit 3 and 79 ± 5 years at Visit 6. From the Zio XT Patch, 5% had continuous AF, 4% had intermittent AF, and 91% had none. After multivariable adjustment, each 1-point increase in LS7 score had 0.87 (95% CI: 0.79 to 0.95) higher odds of continuous AF than no AF. Individually, poor levels of physical activity, BMI, and fasting blood glucose were associated with greater AF burden. In conclusion, this population-based prospective cohort study reports that unfavorable cardiovascular health profile in midlife is associated with higher AF burden in late-life and future research to evaluate the effectiveness of optimizing physical activity, BMI, and fasting blood glucose in lowering AF burden is warranted.

Discordance Between Ldl Cholesterol Versus Particle Concentration And The Cardiovascular Risk Factor Profile

Although low-density lipoprotein cholesterol (LDL-C) levels have been associated with cardiovascular disease (CVD) risk, subjects with well controlled LDL-C are still at considerable residual risk for CVD. Alternative measures such as particle concentration of LDL (LDL-P) may be clinically useful for fully characterizing LDL associated risk. PURPOSE: To compare CVD risk factor profiles among groups of people with discordant levels of LDL-C versus LDL-P concentration in the HERITAGE Family Study. METHODS: Standard lipid panels and lipoprotein subclass profiles via nuclear magnetic resonance (NMR) spectroscopy were measured among 715 participants (34% Black, 55% Female). LDL-C and LDL-P values ≥ the median value were considered high and values < median were considered low. Four exclusive LDL-C/LDL-P groups were identified for LDL from these base categories: 1) low/low (< median for both LDL-C and LDL-P), 2) low/high (< median for LDL-C, ≥ median for LDL-P), 3) high/low, and 4) high/high. Cross-sectional associations between baseline LDL discordance group and CVD risk factors were assessed via multivariable linear regression. All models were adjusted for age, race, and sex. RESULTS: Sixty four (9.0%) participants were discordant with high LDL-C/low LDL-P, while 61 (8.5%) were discordant with low LDL-C/high LDL-P. Both concordant groups (low LDL-C/low LDL-P, high LDL-C/high LDL-P) were composed of 295 participants each (41.3%). Main effects (p<0.05) of LDL discordant group were found for the following outcomes: triglycerides, HDL-C, HDL-P size and small and large HDL-P concentration, percent body fat, maximal oxygen uptake, fasting insulin, lipoprotein lipase activity, testosterone, GlycA, and C-reactive protein. In general, groups with lower LDL-P had more favorable CVD risk factor profiles relative to high LDL-P groups. CONCLUSIONS: In general, low LDL-P levels were associated with favorable CVD risk factor profiles regardless of LDL-C levels.

1601-P: Cardiovascular Risk Profiles among Women by Gestational Diabetes Status, 2007-2016

Background: Women with prior gestational diabetes (GDM) are at elevated risk of type 2 diabetes and cardiovascular disease. We sought to compare cardiometabolic risk factors among parous U.S. women ages 20 to 44 by history of GDM. Methods: We used data from the National Health and Nutrition Examination Survey (NHANES) from 2007-2016. We included 3562 parous women. We compared anthropometric measures, glycemic markers, blood pressure and lipids by self-reported history of GDM, both with and without adjusting for demographic and behavioral factors and waist circumference. Analyses took NHANES multi-stage survey design into account. Results: Women without history of GDM were younger and, in crude analyses, had more favorable cardiometabolic risk factor profile than women with history of GDM (Table). Similar patterns were observed after adjusting for age, race/ethnicity, education and smoking. After also adjusting for waist circumference, only hemoglobin A1c, fasting glucose, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were significantly higher among women with history of GDM compared to women without GDM. Conclusions: Among parous U.S. women ages 20 to 44, those with a history of GDM had less favorable cardiometabolic risk factor profiles than did women without GDM, though results were attenuated after adjusting for markers of demographics, behavior, and central obesity.

Changes in perceptions of neighborhood environment and Cardiometabolic outcomes in two predominantly African American neighborhoods

BackgroundPerceived neighborhood characteristics, including satisfaction with one’s neighborhood as a place to live, are associated with lower obesity rates and more favorable cardiovascular risk factor profiles. Yet, few studies have evaluated whether changes in perceived neighborhood characteristics over time may be associated with cardiometabolic health indicators.MethodsChanges in perception of one’s neighborhood (2013–2016) were determined from a cohort of residents who lived in one of two low-income urban neighborhoods. Changes were categorized into the following: improvement vs. no change or worsening over the three-year time-period. Multivariable linear regression was used to measure the association between perceived improvement in each of the neighborhood characteristics with cardiometabolic outcomes (BMI, SBP, DBP, HbA1c, HDL-c) that were assessed in 2016, and compared with those who perceived no change or worsening of neighborhood characteristics. Models were adjusted for age, sex, income, education, marital status, physical function, neighborhood, and years spent in neighborhood. To examine potential sex differences, follow-up models were conducted and stratified by sex.ResultsAmong the 622 individuals who remained in the same neighborhood during the time period, 93% were African American, 80% were female, and the mean age was 58 years. In covariate-adjusted models, those who perceived improvement in their neighborhood safety over the time period had a significantly higher BMI (kg/m2) than those who perceived no improvement or worsening (β = 1.5, p = 0.0162); however, perceived improvement in safety was also significantly associated with lower SBP (mmHg) (β = − 3.8, p = 0.0361). When results were stratified by sex, the relationship between improved perceived neighborhood safety and BMI was only evident in females.ConclusionsThese findings suggest that perceived neighborhood characteristics may impact cardiometabolic outcomes (BMI, SBP), but through differing pathways. This highlights the complexity of the associations between neighborhood characteristics and underscores the need for more longitudinal studies to confirm the associations with cardiometabolic health in African American populations.

Dietary Intakes and Cardiovascular Health of Healthy Adults in Short-, Medium-, and Long-Term Whole-Food Plant-Based Lifestyle Program.

An effective lifestyle strategy to reduce cardiovascular diseases risk (CVD) factors is needed. We examined the effects of a whole-food plant-based (WFPB) lifestyle program on dietary intake and cardiovascular (CV) risk factors in 151 adults (mean 39.6 (SD 12.5) years). Adherence was categorised into short-, medium- and long-term (years: (0.5–<2), (2–<5) and (5–10)), for both genders separately. Dietary intakes were assessed, fasting blood lipids and blood pressure (BP) were measured, and % participants reaching guideline recommended targets for LDL-cholesterol, triglycerides and BP in the primary CVD prevention was assessed. There were no statistically significant differences in intakes of energy and most nutrients among participants (both genders), that were short-, medium- and long term in our program. Diet was mainly composed of unprocessed vegetables/fruits, whole grains, legumes, potatoes, and nuts/seeds. LDL-cholesterol, triglycerides, systolic and diastolic BP were within targets for: 93%, 97%, 88% and 95% participants, respectively. In females (vs. males), total- and HDL-cholesterol were higher (mean): 3.8 (SD 0.7) vs. 3.4 (SD 0.9), p = 0.002 and 1.5 (SD 0.3) vs. 1.1 (SD 0.2) mmol/L, p < 0.001), systolic BP was lower (113 (SD 11) vs. 120 (SD 10) mmHg, p = 0.001), while there was no difference in diastolic BP (71 (SD 9) vs. 72 (SD 8) mmHg, p = 0.143). More females vs. males reached target triglycerides (99% vs. 91%, p = 0.021) and systolic BP (92% vs. 79%, p = 0.046), while similar females and males reached target LDL-cholesterol (94% vs. 91%, p = 0.500) and diastolic BP (93% vs. 100%, p = 0.107). Participation in our WFPB lifestyle program is associated with favourable dietary intakes, safety markers, and CV risk factor profiles.

CVD risk factors and surrogate markers - Urban-rural differences.

Aims: Disparity in cardiovascular disease (CVD) mortality and risk factor levels between urban and rural regions has been confirmed worldwide. The aim of this study was to examine how living in different community types (urban-rural) in childhood and adulthood are related to cardiovascular risk factors and surrogate markers of CVD such as carotid intima-media thickness (IMT) and left ventricular mass (LVM). Methods: The study population comprised 2903 participants (54.1% female, mean age 10.5 years in 1980) of the Cardiovascular Risk in Young Finns Study who had been clinically examined in 1980 (age 3-18 years) and had participated in at least one adult follow-up (2001-2011). Results: In adulthood, urban residents had lower systolic blood pressure (-1 mmHg), LDL-cholesterol (-0.05 mmol/l), lower body mass index (-1.0 kg/m2) and glycosylated haemoglobin levels (-0.05 mmol/mol), and lower prevalence of metabolic syndrome (19.9 v. 23.7%) than their rural counterparts. In addition, participants continuously living in urban areas had significantly lower IMT (-0.01 mm), LVM (1.59 g/m2.7) and pulse wave velocity (-0.22 m/s) and higher carotid artery compliance (0.07%/10 mmHg) compared to persistently rural residents. The differences in surrogate markers of CVD were only partially attenuated when adjusted for cardiovascular risk factors. Conclusions: Participants living in urban communities had a more favourable cardiovascular risk factor profile than rural residents. Furthermore, participants continuously living in urban areas had less subclinical markers related to CVD compared with participants living in rural areas. Urban-rural differences in cardiovascular health might provide important opportunities for optimizing prevention by targeting areas of highest need.

Vegetarian Diet Patterns and Chronic Disease Risk

Vegetarianism continues to increase globally due, in part, to perceived health benefits. Results from observational studies indicate that vegetarian dietary patterns are associated with favorable cardiometabolic risk factor profiles and lower risks of chronic diseases including obesity, diabetes mellitus type 2, cardiovascular disease, and cancer. Aside from avoidance of meat and the compensatory dietary alterations, vegetarians tend to practice lifestyle habits conducive to better health. Well-controlled intervention trials show minimal or no effects of lean meat intake on traditional markers for chronic disease risk, although biologically plausible mechanisms exist through which consumption of meat and other animal products could influence risks of cardiovascular disease and some cancers. Thus, at present, the degree to which favorable health outcomes associated with vegetarian diet patterns are attributable to avoidance of animal products per se is unclear. This issue has major public health implications because more than 95% of the US population are regular consumers of meat and other animal products. This review aims to summarize the evidence regarding vegetarian diet patterns and major chronic diseases, explore possible explanations for these relationships, and identify research gaps and opportunities to better define the health effects of vegetarian dietary patterns.

Cardiorespiratory fitness as a predictor of short‐term and lifetime estimated cardiovascular disease risk

Development of cardiovascular disease (CVD) remains a public health concern for young to middle-aged adults, now exacerbated by the increasing prevalence of obesity and sedentary lifestyles. Cardiorespiratory fitness (CRF) improves the reclassification of short-term (10-year) CVD risk, but has not been uniformly defined across studies. This study evaluated cross-sectional differences in short-term and lifetime CVD risk scores, across both absolute metabolic equivalent (MET) and sex- and age-standardized CRF categories in 805 apparently healthy young to middle-aged adults (68% male; 47.4±7.2years). CVD risk factors were evaluated, and estimated cardiorespiratory fitness (CRF) measurements (METS and peak VO2 ) were derived from a submaximal Bruce treadmill test. CRF measures also included post-exercise heart rate recovery (HRR) data. Consistent trends showing more favorable risk factor profiles and lower short-term CVD (QRISK2), and CVD mortality (SCORE) scores, associated with higher levels of CRF were evident in both sexes. Lifetime CVD risk (Q-Lifetime) was highest in the lowest CRF categories. Peak VO2 and HRR following submaximal exercise testing contributed to the variability in short-term and lifetime CVD risk. Global CVD risk predictions were examined across different contemporary CRF classifications with inconsistent findings. Recommended absolute MET and sex- and age-standardized CRF categories were significantly associated with both short-term and lifetime risk of CVD outcomes. However, compared to internationally derived normative CRF standards, cohort-specific CRF categories resulted in markedly different proportion of individuals classified in the "poor" CRF category at higher CVD risk.

Impact of socioeconomic status on survival following ST-elevation myocardial infarction in a universal healthcare system

BackgroundLower socioeconomic status (SES) has been associated with worse outcomes after acute myocardial infarction. Data for survival after ST-elevation myocardial infarction (STEMI) by SES in the current era of primary percutaneous coronary intervention (PCI) is more limited. MethodsData was collected for all patients with acute STEMI undergoing primary PCI at The South Yorkshire Cardiothoracic Centre, UK between 2009 and 2014. A Cox regression analysis was used to assess differences in survival by SES quartile (using an area-level measure). ResultsOf the 3126 STEMI patients, 2655 (84.9%) were first presentations of STEMI. Lower SES groups generally had a less favourable baseline cardiovascular risk factor profile, with higher rates of smoking (p = 0.001), diabetes (p = 0.007) and previous coronary heart disease (p = 0.025). With the exception of beta-blockers, the use of secondary preventative medications was similar between SES quartiles. Adjusting for age and gender, the most disadvantaged SES quartile trended to a non-significant increased mortality at 30 days (hazard ratio 1.35 (0.79–2.33)), 1 year (1.12 (0.76–1.65)), or 3 years (1.22 (0.88–1.70)) compared to the least disadvantaged SES quartile, but this was attenuated by adjusting for additional cardiovascular risk factors and medication use on discharge. ConclusionsIn this large study of unselected STEMI patients managed by primary PCI, we did not find any significant differences in survival by SES at 30 days, 1 year, or 3 years.

Coronary heart disease risk factor levels in eastern and western Finland from 1980 to 2011 in the cardiovascular risk in Young Finns study

Background and aimsIn the 1960s and 1970s, Finland, mortality due to coronary heart disease (CHD) was over 30% higher among Finns residing in the east of the country compared with those residing in the west. Today, CHD mortality remains 20% higher among eastern Finns. The higher incidence of CHD mortality among eastern Finns has largely been explained by higher risk factor levels. Using a unique longitudinal cohort, we aimed to determine if participants who resided in eastern Finland during childhood had higher CHD risk factors in adulthood and from childhood to adulthood. MethodsThe study population included 2063 participants of the Cardiovascular Risk in Young Finns Study, born during the period 1962–1977, with risk factor data available from baseline (1980) when participants were aged 3–18 years, and had risk factor data collected again in adulthood (2011) when aged 34–49 years. ResultsAdult CHD risk factor profile was similar for those who resided in eastern or western Finland in childhood. Over life-course from 1980 to 2011, those subjects with childhood residency in eastern Finland had, on average, higher systolic (p = 0.006) and diastolic (p = 0.0009) blood pressures, total (p = 0.01) and LDL-cholesterol (p = 0.01), triglycerides (p = 0.04), apoB (p = 0.02), and serum glucose (p < 0.0001) than those who resided in western Finland in childhood. ConclusionsOur sample of adult Finns aged 34–49 years had a similar CHD risk factor profile irrespective of whether they resided in eastern or western Finland during their childhood. However, when considering participants risk factor profiles over a 31-year period, those who resided in eastern Finland in childhood were associated with a less favorable CHD risk factor profile than those who resided in western Finland in childhood. The observed differences suggest that future CHD mortality might remain higher in eastern Finland compared with western Finland.
