    Abstract: Introduction: Acute myocardial infarction (AMI) is a leading cause of morbidity, mortality, and healthcare costs in the United States (US). Aspirin is an effective, low-cost pharmaceutical that can significantly reduce mortality after AMI. The extent of self-administration of aspirin by individuals at the onset of an AMI is undocumented and must be assumed to be the rare exception. Even among adults admitted to an emergency room, only half receive aspirin within a few hours. Objective: The objective of this study was to evaluate the benefits and potential harms of adults self-administering a single dose of aspirin at the onset of chest pain in the US, including deaths delayed from AMI, deaths due to excessive bleeding, and costs per year of life saved (YOLS). Methods: Estimates of AMI incidence rate from the Global Burden of Disease study and population data from the US Census Bureau were used to derive a study cohort of adults over the age of 40 in the US in 2019. We conducted a systematic review to quantify the positive predictive value of a non-specific chest pain for AMI. A 25% relative risk reduction of mortality, based on the Second International Study of Infarct Survival (ISIS) Trial, was applied to case fatality rates of MI derived from a prior global review study. The main outcome was net deaths delayed from aspirin, calculated from deaths delayed post AMI accounting for deaths from excessive bleeding. Secondary outcomes included YOLS and cost of aspirin/YOLS, calculated summing the YOLS and dividing by total cost of aspirin for all adults experiencing chest pain. All analyses were stratified in 5-year age-sex groups. Results: Assuming all adults over the age of 40 years in the US took aspirin within 2 hours of chest pain onset, the total net deaths delayed in 2019 was estimated to be 81,810. There was a total of 83,226 deaths delayed post AMI, which was offset by 1,417 aspirin-related deaths from excess bleeding, leading to an estimated 869,727 YOLS. The cost of the pills was $423,066, translating to $0.49 per YOLS. Benefits were greatest among males and older adults between ages 65 to 75 years. Conclusions: For less than fifty cents per year of life saved, aspirin has the potential to save over 80,000 lives in the US. Benefits of reducing deaths post AMI outweighed the risk of bleeding from aspirin. As aspirin is cost-effective and easily-accessed, efforts should be made to promote ready access and timely use of aspirin within the first 2 hours of chest pain to reduce mortality associated with AMI in the US and abroad.

    Abstract: Long-term effect of lifestyle changes on stroke incidence has not been estimated in randomized trials. We used observational data to estimate the incidence of stroke under hypothetical lifestyle strategies in the NHS (Nurses’ Health Study). Methods— We considered 3 nondietary strategies (smoking cessation, exercising ≥30 min/d, gradual body mass index reduction if overweight/obese) and several dietary strategies (eating ≥3 servings/wk of fish, ≤3 servings/wk of unprocessed red meat, no processed red meat, ≥1 servings/d of nuts, etc). We used the parametric g-formula to estimate the 26-year risk of stroke under these strategies. Results— In 59 727 women, mean age 52 years at baseline in 1986, the estimated 26-year risks under no lifestyle interventions were 4.7% for total stroke, 2.4% for ischemic stroke, and 0.7% for hemorrhagic stroke. Under the combined nondietary interventions, the estimated 26-year risk of total stroke was 3.5% (95% CI, 2.6%–4.3%) and ischemic stroke was 1.6% (95% CI, 1.1%–2.1%). Smaller reductions in total stroke risk were estimated under isolated dietary strategies of increased intake of fish and nuts and reduced intake of unprocessed red meat. Ischemic stroke risk was lower under reduced intake of unprocessed and processed red meat, and hemorrhagic stroke risk was lower under a strategy of increased fish consumption. Conclusions— In this population of middle-aged women, sustained, lifestyle modifications were estimated to reduce the 26-year risk of total stroke by 25% and ischemic stroke by 36%. Sustained dietary modifications were estimated to reduce the 26-year risk of total stroke by 23%.

    Abstract: With the increasing focus on reducing hospital readmissions in the United States, numerous readmissions risk prediction models have been proposed, mostly developed through analyses of structured data fields in electronic medical records and administrative databases. Three areas that may have an impact on readmission but are poorly captured using structured data sources are patients’ physical function, cognitive status, and psychosocial environment and support. Objective of the Study: The objective of the study was to build a discriminative model using information germane to these 3 areas to identify hospitalized patients’ risk for 30-day all cause readmissions. Research Design: We conducted clinician focus groups to identify language used in the clinical record regarding these 3 areas. We then created a dataset including 30,000 inpatients, 10,000 from each of 3 hospitals, and searched those records for the focus group-derived language using natural language processing. A 30-day readmission prediction model was developed on 75% of the dataset and validated on the other 25% and also on hospital specific subsets. Results: Focus group language was aggregated into 35 variables. The final model had 16 variables, a validated C-statistic of 0.74, and was well calibrated. Subset validation of the model by hospital yielded C-statistics of 0.70–0.75. Conclusions: Deriving a 30-day readmission risk prediction model through identification of physical, cognitive, and psychosocial issues using natural language processing yielded a model that performs similarly to the better performing models previously published with the added advantage of being based on clinically relevant factors and also automated and scalable. Because of the clinical relevance of the variables in the model, future research may be able to test if targeting interventions to identified risks results in reductions in readmissions.

    Abstract: Introduction: Health disparities remain pervasive in US and eliminating such disparities is one of the overarching goals of the Healthy People 2020 agenda. Previous studies have assessed the disparities in risk of coronary heart disease (CHD) mortality by race/ethnicity, but most of them only focused on the average CHD risk without taking into account the full risk distribution which would enable analysis of specific high-risk sub-groups. In this study, we estimated the 10-year risk distribution of CHD mortality based on 5 leading modifiable risk factors in US (i.e. smoking, adiposity, high blood pressure, serum cholesterol and blood glucose). We quantified the racial disparities in absolute CHD risk while accounting for full risk distribution. Methods: We included 3866 individuals aged 45 to 74 years, who were black or white, non-pregnant, free of CHD and had measurements of all 5 risk factors from 6 consecutive 2-year cycles of the National Health and Nutrition Examination Survey 1999-2010. We used mortality data from National Center for Health Statistics to estimate the cause-age-sex-race specific mortality in 2010. We also obtained hazard ratios of the selected 5 risk factors on CHD mortality from large meta-analyses of epidemiological studies. We predicted the 10-year risk of CHD death for each individual by simulating their survival process from 2010 to 2020 incorporating competing risks by death from other correlated causes. To assess health disparities, we compared the 5 th , 25 th , 50 th , 75 th and 95 th percentile of the predicted risks between black and white by age and sex. Results: More than half of the black and white population aged 45 to 74 years had a low 10-year risk of CHD death ( 〈 2%). The age-sex-race specific distributions of 10-year CHD risk were right-skewed with a large proportion of population on the low risk tail. Comparing to white, black had similar shape of CHD risk distributions, but higher risk levels at all percentiles across age and sex groups. In 55-64 ages where CHD was the major cause of death, the median of CHD risk for black males was 2.9% (interquartile range (IQR) 1.7% - 4.4%), which was 0.7% larger than that for white males (2.2%, IQR 1.4% - 3.3%). This risk difference was similar in females: the median CHD risk for black females was 1.6% (IQR 0.9% - 2.4%) and 0.9% for white females (IQR 0.5% - 1.5%). The disparities became larger on the high risk tail (95 th percentile of predicted risk), where black had 2.7% higher risk for male and 2.3% for female in 55-64 ages. In older age groups (65-74 ages), such difference increased to 3.5% for both male and female. Conclusions: This analysis showed a skewed 10-year CHD risk distribution in US. The racial disparities are larger in the high risk sub-groups compared to those in the center of the risk distribution, indicating that the high risk subgroups should be the target population of intervention that aims to reduce health disparities in US.

    Abstract: Randomized trials have examined the short-term effects of lifestyle interventions on the risk of stroke. Using observational data to estimate the long-term effect of such strategies requires valid adjustment for time-varying confounders- such as hypertension- that are affected by prior lifestyle risk factors. We estimated the long-term effect of hypothetical lifestyle strategies on risk of stroke using data from the Nurses’ Health Study, a prospective cohort. We followed 60,390 women, aged 52 years on average at baseline, from 1986 to 2010. We used a Monte Carlo simulation to estimate the 24-year risk of stroke had all participants followed three non-dietary lifestyle strategies: smoking cessation, exercising (≥30 minutes/day), reducing body mass index (BMI) by 5% every two years if overweight/obese; as well as several dietary strategies including: eating ≥ 3 servings/week of fish, eating ≤ 3 servings/week of unprocessed red meat, eating no processed red meat, eating ≥ 5 servings/day of fruits and vegetables, among others. We used the parametric g-formula to adjust for baseline and time-varying confounders, comparing the estimated risk of stroke under our specified strategies of interest to the same had all participants followed a “do-nothing” strategy. The observed 24-year risks of total, ischemic and hemorrhagic stroke in this cohort were 2.9%, 2.2% and 0.6%. The estimated risk of total stroke was 25% lower (95% CI: 5% to 46%) under a combination of all three non-dietary strategies, the most effective being exercise (19% lower risk) and smoking cessation (5% lower risk). Of the dietary strategies, eating ≤ 3 servings of unprocessed red meat reduced the estimated risk of total stroke by 4% (1% to 7%). The risk of ischemic stroke under all three non-dietary strategies was 36% lower (15% to 59%), but risk of hemorrhagic stroke did not materially change. Exercise reduced the estimated risk of ischemic stroke by 29% (7% to 56%) and lowering BMI by 4% (0% to 8%). Additionally, ischemic stroke risk was lowered by 9% (0% to 19%) by decreasing intake of processed red meat and 6% (2% to 10%) by decreasing intake of unprocessed red meat. In summary, lifestyle modifications were estimated to reduce the 24-year risk of total stroke by up to 25% in this population of middle-aged women.

    Abstract: Introduction: Increasing the prevalence of the ideal cardiovascular health (CVH) phenotype over the coming decades would likely result in dramatic improvements in healthy longevity and reductions in healthcare costs. Therefore, it is of paramount importance to understand the global prevalence and trends of the ideal CVH behaviors and factors for monitoring progress and providing evidence to support policy efforts. Hypothesis: We aim to describe the prevalence of CVH for the AHA defined metrics of tobacco use, body mass index, total cholesterol, blood pressure and glucose levels, and estimate its trends worldwide. Methods: We used data from people aged 〉 20 years who participated in 68 national health examination surveys from 1983 to 2017 in 18 countries: Australia, Czech Republic, Denmark, Germany, Greece, Ireland, Italy, Malaysia, Mexico, Poland, Seychelles, Slovakia, South Korea, Spain, Sweden, Turkey, the UK, and the USA. We calculated age-standardized prevalence of ideal CVH (no current smoking, BMI 〈 25 kg/m2, untreated TC 〈 200 mg/dL, untreated BP 〈 120 / 〈 80 mmHg, and absence of diabetes mellitus). Additionally, we examined the trends of the ideal CVH for countries that had at least two individual-level national surveys in two different decades (2000-2009 vs 2010-2019). Results: With the exception of Australia and South Korea, age-standardized prevalence of idea CVH was lower than 10% in women and lower than 5% in men across all countries. Older individuals had a lower prevalence of Ideal CVH than younger ones. Those over 65 years of age had a prevalence almost equal to zero. In ages 35-64 years, ideal CVH prevalence ranged from 3.6% to 25.4% among women, and from 0.6% to 7.1% among men. For the 10 countries where trends were estimated by age-sex groups, ideal CVH prevalence did not change or declined in the selected middle-income countries and increased in the selected high-income countries except for South Korea, where it plateaued for men and declined for women. Conclusions: Prevalence of ideal CVH worldwide is low and is declining for adults in middle-income countries in recent decades.

    Abstract: Introduction: In Argentina physical inactivity was the fifth leading risk factor for all-cause mortality in 2010. The aim of this project was to estimate the numbers of ischaemic heart disease (IHD) and stroke deaths in Argentina attributable to different levels of physical activity (PA). Materials and Methods: We conducted a population-level comparative risk assessment for different levels of PA. We obtained data on prevalence of different levels of PA from the Argentinian national survey of risk factors 2013 and used relative risk for stroke and IHD mortality from prior meta-analyses for each category of PA. The number of disease-specific deaths, by age and sex, were obtained from the vital registration system for the year 2010. We considered 4 categories of PA based on the metabolic equivalent tasks per minute per week (MET/minute/week): inactive, 〈 600, ≥ 600 to 〈 1,600 and ≥1,600. We calculated the population attributable fraction for different levels of PA by sex and age group. Results: In Argentina, 76.5% (CI 95%; 75.8-77.7) of the total population engaged 〈 1,600 MET/min/week (72.8% in men and 81.1% in women). This level of insufficient activity was responsible for 26% of all IHD and stroke deaths in 2010 (11,234 of 43,796 deaths; 6,013 in men and 5,221 in women). It was also responsible for 29% (7,292) of the total IHD deaths and 21% (3,942) of the total stroke deaths. Almost half of the population or 52.5% (CI 95%; 51.3-53.7) engaged 〈 600 MET/minutes/week (48.8% in men and 55.7% in women) and this level of inactivity was responsible for 17% (7,278 of 43,796 deaths) of all IHD and stroke deaths in 2010 (3,941 in men and 3,337 in women). It was also responsible for 20% (4,907) of the IHD deaths and 13% (2,371) of the stroke deaths The impact of physical inactivity and insufficient PA was higher in women due to lower level of PA compared to men and in the individuals younger than 70 years old due to a stronger association with the outcomes (higher relative risks), especially for IHD. Conclusions: Physical inactivity and insufficient physical activity contribute substantially to the burden of cardiovascular diseases in Argentina. Interventions to promote PA should be a priority to prevent cardiovascular disease.

    Abstract: Preventable noncommunicable diseases, mostly cardiovascular diseases, are responsible for 38 million deaths annually. A few well-documented interventions have the potential to prevent many of these deaths, but a large proportion of the population in need does not have access to these interventions. We quantified the global mortality impact of 3 high-impact and feasible interventions: scaling up treatment of high blood pressure to 70%, reducing sodium intake by 30%, and eliminating the intake of artificial trans fatty acids. Methods: We used global data on mean blood pressure levels and sodium and trans fat intake by country, age, and sex from a pooled analysis of population health surveys, and regional estimates of current coverage of antihypertensive medications, and cause-specific mortality rates in each country, as well, with projections from 2015 to 2040. We used the most recent meta-analyses of epidemiological studies to derive relative risk reductions for each intervention. We estimated the proportional effect of each intervention on reducing mortality from related causes by using a generalized version of the population-attributable fraction. The effect of antihypertensive medications and lowering sodium intake were modeled through their impact on blood pressure and as immediate increase/reduction to the proposed targets. Results: The combined effect of the 3 interventions delayed 94.3 million (95% uncertainty interval, 85.7–102.7) deaths during 25 years. Increasing coverage of antihypertensive medications to 70% alone would delay 39.4 million deaths (35.9–43.0), whereas reducing sodium intake by 30% would delay another 40.0 million deaths (35.1–44.6) and eliminating trans fat would delay an additional 14.8 million (14.7–15.0). The estimated impact of trans fat elimination was largest in South Asia. Sub-Saharan Africa had the largest proportion of premature delayed deaths out of all delayed deaths. Conclusions: Three effective interventions can save almost 100 million lives globally within 25 years. National and international efforts to scale up these interventions should be a focus of cardiovascular disease prevention programs.

    Abstract: Background— Blood pressure is an important risk factor for cardiovascular disease and mortality and has lifestyle and healthcare determinants that vary across states. Only self-reported hypertension status is measured at the state level in the United States. Our aim was to estimate levels and trends in state-level mean systolic blood pressure (SBP), the prevalence of uncontrolled systolic hypertension, and cardiovascular mortality attributable to all levels of higher-than-optimal SBP. Methods and Results— We estimated the relationship between actual SBP/uncontrolled hypertension and self-reported hypertension, use of blood pressure medication, and a set of health system and sociodemographic variables in the nationally representative National Health and Nutrition Examination Survey. We applied this relationship to identical variables from the Behavioral Risk Factor Surveillance System to estimate state-specific mean SBP and uncontrolled hypertension. We used the comparative risk assessment methods to estimate cardiovascular mortality attributable to higher-than-optimal SBP. In 2001–2003, age-standardized uncontrolled hypertension prevalence was highest in the District of Columbia, Mississippi, Louisiana, Alabama, Texas, Georgia, and South Carolina (18% to 21% for men and 24% to 26% for women) and lowest in Vermont, Minnesota, Connecticut, New Hampshire, Iowa, and Colorado (15% to 16% for men and ≈21% for women). Women had a higher prevalence of uncontrolled hypertension than men in every state by 4 (Arizona) to 7 (Kansas) percentage points. In the 1990s, uncontrolled hypertension in women increased the most in Idaho and Oregon (by 6 percentage points) and the least in the District of Columbia and Mississippi (by 3 percentage points). For men, the worst-performing states were New Mexico and Louisiana (decrease of 0.6 and 1.3 percentage points), and the best-performing states were Vermont and Indiana (decrease of 4 and 3 percentage points). Age-standardized cardiovascular mortality attributable to higher-than-optimal SBP ranged from 200 to 220 per 100 000 (Minnesota and Massachusetts) to 360 to 370 per 100 000 (District of Columbia and Mississippi) for women and from 210 per 100 000 (Colorado and Utah) to 370 per 100 000 (Mississippi) and 410 per 100 000 (District of Columbia) for men. Conclusions— Lifestyle and pharmacological interventions for lowering blood pressure are particularly needed in the South and Appalachia, and with emphasis on control among women. Self-reported data on hypertension diagnosis from the Behavioral Risk Factor Surveillance System can be used to obtain unbiased state-level estimates of blood pressure and uncontrolled hypertension as benchmarks for priority setting and for designing and evaluating intervention programs.
