Incident Cardiovascular Disease

Background: Smoke-free legislation has been associated with lower rates of cardiovascular disease hospital admissions in ecological studies. However, prior studies lacked detailed information on individual-level factors (eg, sociodemographic and clinical characteristics) that could potentially confound associations. Our objective was to estimate associations of smoke-free policies with incident cardiovascular disease in a longitudinal cohort after controlling for sociodemographics, cardiovascular disease risk factors, and policy covariates. Methods: Longitudinal data from 3783 black and white adults in the CARDIA study (Coronary Artery Risk Development in Young Adults; 1995–2015) were linked to state, county, and local 100% smoke-free policies in bars, restaurants, and nonhospitality workplaces by Census tract. Extended Cox regression estimated hazard ratios (HRs) of incident cardiovascular disease associated with time-dependent smoke-free policy exposures. Models were adjusted for sociodemographic characteristics, cardiovascular disease risk factors, state cigarette tax, participant-reported presence of a smoking ban at their workplace, field center, and metropolitan statistical area poverty. Results: During a median follow-up of 20 years (68 332 total person-years), 172 participants had an incident cardiovascular disease event (2.5 per 1000 person-years). Over the follow-up period, 80% of participants lived in areas with smoke-free policies in restaurants, 67% in bars, and 65% in nonhospitality workplaces. In fully adjusted models, participants living in an area with a restaurant, bar, or workplace smoke-free policy had a lower risk of incident cardiovascular disease compared with those in areas without smoke-free policies (HR, 0.75, 95% confidence interval, 0.49–1.15; HR, 0.76, 95% confidence interval, 0.47–1.24; HR, 0.54, 95% confidence interval, 0.34–0.86, respectively; HR, 0.58, 95% confidence interval, 0.33–1.00 for living in an area with all 3 types of policies compared with none). The estimated preventive fraction was 25% for restaurant policies, 24% for bar policies, and 46% for workplace policies. Conclusions: Consistent with prior ecological studies, these individual-based data add to the evidence that 100% smoke-free policies are associated with lower risk of cardiovascular disease among middle-aged adults.

Incident Cardiovascular Disease

Background Recent studies have investigated the association of transitions in metabolic health and obesity status over time with the risk of cardiovascular disease, focusing on the subgroup demonstrating metabolically healthy obesity. However, these studies have produced inconsistent results. This study evaluates the relation in a general Chinese population. Methods We conducted a prospective cohort study in a general population in Northeast China, with examinations of cardiovascular health from 2012–2015 and follow-up for incident cardiovascular disease until 2018. Cox proportional hazards and logistic regression models were used to investigate the association of baseline metabolic health and obesity status and transitions in those statuses with cardiovascular disease risk. Results A total of 7472 participants aged ≥35 years who were free of cardiovascular disease at baseline were included in this analysis. Over a median follow-up of 4.66 years, a total of 344 cardiovascular disease events occurred. Among the 3380 participants who were obese at baseline, 37.1% were metabolically healthy. Metabolically healthy obesity was associated with a 48% increased risk of cardiovascular disease (hazard ratio: 1.48; 95% confidence interval: 1.07–2.06) compared with the metabolically healthy non-obese group at baseline. Transition from metabolically healthy obesity to metabolically unhealthy obesity was associated with elevated cardiovascular disease risk with an odds ratio of 1.82 (95% confidence interval: 1.06–3.14) compared with metabolically healthy non-obesity throughout after adjustment. Even maintaining metabolically healthy obesity over time was associated with a higher risk of cardiovascular disease (odds ratio: 1.72; 95% confidence interval: 1.00–2.97). Conclusions Weight control and management of existing metabolic disorders should be prioritized in all obese population.

The Relationship

Vascular injury mobilizes bone marrow–derived proangiogenic cells into the circulation, where these cells can facilitate vascular repair and new vessel formation. We sought to determine the relationship between a new biomarker of circulating bone marrow–derived proangiogenic cell activity, the presence of atherosclerotic cardiovascular disease (CVD) and its risk factors, and clinical outcomes. Circulating proangiogenic cell activity was estimated using a reproducible angiogenic colony-forming unit (CFU-A) assay in 532 clinically stable subjects aged 20 to 90 years and ranging in the CVD risk spectrum from those who are healthy without risk factors to those with active CVD. CFU-A counts increased with the burden of CVD risk factors ( p < 0.001). CFU-A counts were higher in subjects with symptomatic CVD than in those without ( p < 0.001). During follow-up of 232 subjects with CVD, CFU-A counts were higher in those with death, myocardial infarction, or stroke than in those without (110 [70–173] vs 84 [51–136], p = 0.01). Therefore, we conclude that circulating proangiogenic cell activity, as estimated by CFU-A counts, increases with CVD risk factor burden and in the presence of established CVD. Furthermore, higher circulating proangiogenic cell activity is associated with worse clinical outcome in those with CVD.

Over Time

Background There is increasing evidence of an association between social relationships and morbidity in general, and cardiovascular disease in particular. However, recent syntheses of the evidence raise two important questions: is it the perceived quality or the more objective quantity of relationships that matters most; and what are the implications of changes in relationships over time? In this study, we investigate the cumulative effects of loneliness and social isolation on incident cardiovascular disease. Design A secondary analysis of prospective follow-up data from the English Longitudinal Study of Ageing (ELSA). Methods To assess the association between social isolation or loneliness and incident cardiovascular disease, lagged values of exposure to loneliness and isolation were treated as time-varying variables in discrete time survival models controlling for potential confounders and established cardiovascular disease risk factors. Results A total of 5397 men and women aged over 50 years were followed up for new fatal and non-fatal diagnoses of heart disease and stroke between 2004 and 2010. Over a mean follow-up period of 5.4 years, 571 new cardiovascular events were recorded. We found that loneliness was associated with an increased risk of cardiovascular disease (odds ratio 1.27, 95% confidence interval 1.01–1.57). Social isolation, meanwhile, was not associated with disease incidence. There was no evidence of a cumulative effect over time of social relationships on cardiovascular disease risk. Conclusions Loneliness is associated with an increased risk of developing coronary heart disease and stroke, independently of traditional cardiovascular disease risk factors. Our findings suggest that primary prevention strategies targeting loneliness could help to prevent cardiovascular disease.
