- Background-Diabetes mellitus (DM) is common in patients hospitalized with an acute myocardial infarction (AMI), representing in some cases the first opportunity to recognize and treat DM. We report the incidence of new DM and its recognition among patients with AMI. Methods and Results-Patients in a 24-site US AMI registry (2005-08) had glycosylated hemoglobin assessed at a core laboratory, with results blinded to clinicians and local clinical measurements left to the discretion of the treating providers. Among 2854 AMI patients without known DM on admission, 287 patients (10%) met criteria for previously unknown DM, defined by a core laboratory glycosylated hemoglobin of >= 6.5%. Among these, 186 (65%) were unrecognized by treating clinicians, receiving neither DM education, glucose-lowering medications at discharge, nor documentation of DM in the chart (median glycosylated hemoglobin of unrecognized patients, 6.7%; range, 6.5-12.3%). Six months after discharge, only 5% of those not recognized as having DM during hospitalization had been initiated on glucose-lowering medications versus 66% of those recognized (P< 0.001). Conclusions-Underlying DM that has not been previously diagnosed is common among AMI patients, affecting 1 in 10 patients, yet is recognized by the care team only one third of the time. Given its frequency and therapeutic implications, including but extending beyond the initiation of glucose-lowering treatment, consideration should be given to screening all AMI patients for DM during hospitalization. Inexpensive, ubiquitous, and endorsed as an acceptable screen for DM, glycosylated hemoglobin testing should be considered for this purpose.

- BACKGROUND: Deep neural networks have been used to estimate age from ECGs, the electrocardiographic age (ECG-age), which predicts adverse outcomes. However, this prediction ability has been restricted to clinical settings or relatively short periods. We hypothesized that ECG-age is associated with death and cardiovascular outcomes in the long-standing community-based FHS (Framingham Heart Study).METHODS: We tested the association of ECG-age with chronological age in the FHS cohorts in ECGs from 1986 to 2021. We calculated the gap between chronological and ECG-age (& UDelta;age) and classified individuals as having normal, accelerated, or decelerated aging, if & UDelta;age was within, higher, or lower than the mean absolute error of the model, respectively. We assessed the associations of & UDelta;age, accelerated and decelerated aging with death or cardiovascular outcomes (atrial fibrillation, myocardial infarction, and heart failure) using Cox proportional hazards models adjusted for age, sex, and clinical factors.RESULTS:The study population included 9877 FHS participants (mean age, 55 & PLUSMN;13 years; 54.9% women) with 34 948 ECGs. ECG-age was correlated to chronological age (r=0.81; mean absolute error, 9 & PLUSMN;7 years). After 17 & PLUSMN;8 years of follow-up, every 10-year increase of & UDelta;age was associated with 18% increase in all-cause mortality (hazard ratio [HR], 1.18 [95% CI, 1.12-1.23]), 23% increase in atrial fibrillation risk (HR, 1.23 [95% CI, 1.17-1.29]), 14% increase in myocardial infarction risk (HR, 1.14 [95% CI, 1.05-1.23]), and 40% increase in heart failure risk (HR, 1.40 [95% CI, 1.30-1.52]), in multivariable models. In addition, accelerated aging was associated with a 28% increase in all-cause mortality (HR, 1.28 [95% CI, 1.14-1.45]), whereas decelerated aging was associated with a 16% decrease (HR, 0.84 [95% CI, 0.74-0.95]).CONCLUSIONS:ECG-age was highly correlated with chronological age in FHS. The difference between ECG-age and chronological age was associated with death, myocardial infarction, atrial fibrillation, and heart failure. Given the wide availability and low cost of ECG, ECG-age could be a scalable biomarker of cardiovascular risk.

- BACKGROUND: Sub-Saharan Africa is undergoing an epidemiological transition fueled by the interaction between infectious and cardiovascular diseases. Our cross-sectional study aimed to characterize the spectrum of abnormalities suggesting end-organ damage on ECG and transthoracic echocardiograms (TTE) among older adults with cardiovascular diseases in rural South Africa.METHODS: The prevalence of ECG and TTE abnormalities was estimated; χ2 analyses and multivariable logistic regressions were performed to test their association with sex, hypertension, and other selected comorbidities.RESULTS: Overall, 729 ECGs and 155 TTEs were completed, with 74 participants completing both. ECG evaluation showed high rates of left ventricular hypertrophy (LVH, 36.5%) and T wave abnormalities (13.6%). TTE evaluation showed high rates of concentric LVH (31.6%), with moderate-severe (56.8%) diastolic dysfunction. Participants with hypertension showed more cardiac remodeling on ECG by LVH (45.4% versus 22.1%, P<0.01), and TTE by concentric LVH (42.5% versus 8.2%, P<0.01) and increased left ventricular mass (58.5% versus 20.4%, P<0.0001). In multivariable logistic regression, systolic blood pressure remained significantly associated with LVH on ECG (adjusted odds ratio, 1.03 per mm Hg [95% CI, 1.03-1.04], P<0.0001) and increased left ventricular mass on TTE (adjusted odds ratio, 1.04 per mm Hg [95% CI, 1.01-1.06], P=0.001). Male participants (n=326, 40.2%) were more likely than females (n=484, 59.8%) to show ECG abnormalities like LVH (45% versus 30.8%, P<0.01), whereas females were more likely to show TTE abnormalities like concentric LVH (40.8% versus 13.5%, P<0.01) and increased left ventricular mass (58.4% versus 23.1%, P<0.0001). Similar results were confirmed in multivariable models.CONCLUSIONS: Our findings suggest that cardiovascular diseases are widespread in rural South Africa, with a larger burden of hypertensive heart disease than previously appreciated, and define the severity of end-organ damage that is already underway. Local health systems must adapt to face the growing burden of hypertension, as suboptimal rates of hypertension diagnosis and treatment may dramatically increase the heart failure burden.

- BACKGROUND: The aim of this study was to describe out-of-hospital cardiac arrest (OHCA) survivors' ability to participate in activities of everyday life and society, including return to work. The specific aim was to evaluate potential effects of cognitive impairment. METHODS AND RESULTS: Two hundred eighty-seven OHCA survivors included in the TTM trial (Target Temperature Management) and 119 matched control patients with ST-segment-elevation myocardial infarction participated in a follow-up 180 days post-event that included assessments of participation, return to work, emotional problems, and cognitive impairment. On the Mayo-Portland Adaptability Inventory-4 Participation Index, OHCA survivors (n=270) reported more restricted participation In everyday life and in society (47% versus 30%; P<0.001) compared with ST-segment-elevation myocardial infarction controls (n=118). Furthermore, 27% (n=36) of pre-event working OHCA survivors (n=135) compared with 7% (n=3) of pre-event working ST-segment-elevation myocardial infarction controls (n=45) were on sick leave (odds ratio, 4.9; 95% confidence interval, 1.4-16.8; P=0.01). Among the OHCA survivors assumed to return to work (n=135), those with cognitive impairment (n=55) were 3x more likely (odds ratio, 3.3; 95% confidence interval, 1.2-9.3; P=0.02) to be on sick leave compared with those without cognitive impairment (n=40; 36%, n=20, versus 15%, n=6). For OHCA survivors, the variables that were found most predictive for a lower participation were depression, restricted mobility, memory impairment, novel problem-solving difficulties, fatigue, and slower processing speed. CONCLUSIONS: OHCA survivors reported a more restricted societal participation 6 months post-arrest, and their return to work was lower compared with ST-segment-elevation myocardial infarction controls. Cognitive impairment was significantly associated with lower participation, together with the closely related symptoms of fatigue, depression, and restricted mobility. These predictive variables may be used during follow-up to identify OHCA survivors at risk of a less successful recovery that may benefit from further support and rehabilitation.

- Background-Elderly patients with acute coronary syndrome are at high risk of recurrent ischemic events and death, and for both antithrombotic therapy and catheter-based complications. This prespecified analysis investigates the effect and treatment-related complications of ticagrelor versus clopidogrel in elderly patients (>= 75 years of age) with acute coronary syndrome compared with those < 75 years of age. Methods and Results-The association between age and the primary composite outcome, as well as major bleeding were evaluated in the PLATelet inhibition and patient Outcomes (PLATO) trial using Cox proportional hazards. Similar models were used to evaluate the interaction of age with treatment effects. Hazard ratios were adjusted for baseline characteristics. The clinical benefit of ticagrelor over clopidogrel was not significantly different between patients aged >= 75 years of age (n=2878) and those < 75 years of age (n=15744) with respect to the composite of cardiovascular death, myocardial infarction, or stroke (interaction P=0.56), myocardial infarction (P=0.33), cardiovascular death (P=0.47), definite stent thrombosis (P=0.81), or all-cause mortality (P=0.76). No increase in PLATO-defined overall major bleeding with ticagrelor versus clopidogrel was observed in patients aged >= 75 years (hazard ratio, 1.02; 95% confidence interval, 0.82-1.27) or patients aged < 75 years (hazard ratio, 1.04; 95% confidence interval, 0.94-1.15). Dyspnea and ventricular pauses were more common during ticagrelor than clopidogrel treatment, with no evidence of an age-by-treatment interaction. Conclusions-The significant clinical benefit and overall safety of ticagrelor compared with clopidogrel in acute coronary syndrome patients in the PLATO cohort were not found to depend on age.

- Background Incidence, any trend over time, and predictors of ischemic stroke after an acute myocardial infarction (AMI) in diabetic patients are unknown.Methods and Results Data for 173 233 unselected patients with an AMI, including 33 503 patients with diabetes mellitus, were taken from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS-HIA) during 1998 to 2008. Ischemic stroke events were recorded during 1 year of follow-up. Patients with diabetes mellitus more often had a history of cardiovascular disease, received less reperfusion therapy, and were treated with acetylsalicylic acid, P2Y12 inhibitors, and statins to a lesser extent compared with patients without diabetes mellitus. However, the use of evidence-based therapies increased markedly in both groups during the study period. The incidence of ischemic stroke during the first year after AMI decreased from 7.1% to 4.7% in patients with diabetes mellitus and from 4.2% to 3.7% in patients without diabetes mellitus. Risk reduction was significantly larger in the diabetic subgroup. Reperfusion therapy, acetylsalicylic acid, P2Y12 inhibitors, and statins were independently associated with the reduced stroke risk.Conclusions Ischemic stroke is a fairly common complication after an AMI in patients with diabetes mellitus, but the risk of stroke has decreased during recent years. The increased use of evidence-based therapies contributes importantly to this risk reduction, but there is still room for improvement.

- Background-The TRAPID-AMI trial study ( High-Sensitivity Troponin-T Assay for Rapid Rule-Out of Acute Myocardial Infarction) evaluated high-sensitivity cardiac troponin-T ( hs-cTnT) in a 1-hour acute myocardial infarction ( AMI) exclusion algorithm. Our study objective was to evaluate the prognostic utility of a modified HEART score ( m-HS) within this trial. Methods and Results-Twelve centers evaluated 1282 patients in the emergency department for possible AMI from 2011 to 2013. Measurements of hs-cTnT ( 99th percentile, 14 ng/L) were performed at 0, 1, 2, and 4 to 14 hours. Evaluation for major adverse cardiac events ( MACEs) occurred at 30 days ( death or AMI). Low-risk patients had an m-HS <= 3 and had either hs-cTnT<14 ng/L over serial testing or had AMI excluded by the 1-hour protocol. By the 1-hour protocol, 777 ( 60%) patients had an AMI excluded. Of those 777 patients, 515 ( 66.3%) patients had an m-HS <= 3, with 1 ( 0.2%) patient having a MACE, and 262 ( 33.7%) patients had an m-HS <= 4, with 6 ( 2.3%) patients having MACEs ( P=0.007). Over 4 to 14 hours, 661 patients had a hs-cTnT<14 ng/L. Of those 661 patients, 413 ( 62.5%) patients had an m-HS <= 3, with 1 ( 0.2%) patient having a MACE, and 248 ( 37.5%) patients had an m-HS >= 4, with 5 ( 2.0%) patients having MACEs ( P=0.03). Conclusions-Serial testing of hs-cTnT over 1 hour along with application of an m-HS identified a low-risk population that might be able to be directly discharged from the emergency department.

- Background: Dog ownership is associated with increased physical activity levels and increased social support, both of which could improve the outcome after a major cardiovascular event. Dog ownership may be particularly important in single-occupancy households where ownership provides substitutive companionship and motivation for physical activity.Methods and Results: We used the Swedish National Patient Register to identify all patients aged 40 to 85 presenting with an acute myocardial infarction (n=181 696; 5.7% dog ownership) or ischemic stroke (n=154 617; 4.8% dog ownership) between January 1, 2001 and December 31, 2012. Individual information was linked across registers for cause of death, sociodemographic, and dog ownership data. We evaluated all-cause mortality and risk of recurrent hospitalization for the same cause until December 31, 2012. Models were adjusted for socioeconomic, health, and demographic factors at study inclusion such as age, marital status, the presence of children in the home, area of residence, and income, as well as all registered comorbidities and hospitalization for cardiovascular disease in the past 5 years. Dog owners had a lower risk of death after hospitalization for acute myocardial infarction during the full follow-up period of 804 137 person-years, with an adjusted hazard ratio (HR) of 0.67 (95% CI, 0.61 to 0.75) for those who lived alone, and HR of 0.85 (95% CI, 0.80 to 0.90) for those living with a partner or a child. Similarly, after an ischemic stroke, dog owners were at lower risk of death during the full follow-up of 638 219 person-years adjusted HR of 0.73 (95% CI, 0.66 to 0.80) for those who lived alone and HR of 0.88 (95% CI, 0.83 to 0.93) for those living with a partner or a child. We further found an association of dog ownership with reduced risk of hospitalization for recurrent myocardial infarction (HR, 0.93; 95% CI, 0.87 to 0.99).Conclusions: We found evidence of an association of dog ownership with a better outcome after a major cardiovascular event. Although our models are adjusted for many potential confounders, there are also unmeasured confounders such as smoking that prevent us from drawing conclusions regarding a possible causal effect.

- BACKGROUND: Suspected myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) occurs in ≈5% to 10% of patients with MI referred for coronary angiography. The prognosis of these patients may differ to those with MI and obstructive coronary artery disease (MI-CAD) and those without a MI (patients without known history of MI [No-MI]). The primary objective of this study is to evaluate the 12-month all-cause mortality of patients with MINOCA.METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the terms "MI," "nonobstructive," "angiography," and "prognosis" were searched in PubMed and Embase databases from inception to December 2018, including original, English language MINOCA studies with >100 consecutive patients. Publications with a heterogeneous cohort, unreported coronary stenosis, or exclusively focusing on MINOCA-mimicking conditions, were excluded. Unpublished data were obtained from the MINOCA Global Collaboration. Data were pooled and analyzed using Paule-Mandel, Hartung, Knapp, Sidik & Jonkman, or restricted maximum-likelihood random-effects meta-analysis methodology. Heterogeneity was assessed using Cochran's Q and I2 statistics. The primary outcome was 12-month all-cause mortality in patients with MINOCA, with secondary comparisons to MI-CAD and No-MI.RESULTS: The 23 eligible studies yielded 55 369 suspected MINOCA, 485 382 MI-CAD, and 33 074 No-MI. Pooled meta-analysis of 14 MINOCA studies accounting for 30 733 patients revealed an unadjusted 12-month all-cause mortality rate of 3.4% (95% CI, 2.6%-4.2%) and reinfarction (n=27 605; 10 studies) in 2.6% (95% CI, 1.7%-3.5%). MINOCA had a lower 12-month all-cause mortality than those with MI-CAD (3.3% [95% CI, 2.5%-4.1%] versus 5.6% [95% CI, 4.1%-7.0%]; odds ratio, 0.60 [95% CI, 0.52-0.70], P<0.001). In contrast, there was a statistically nonsignificant trend towards increased 12-month all-cause mortality in patients with MINOCA (2.6% [95% CI, 0%-5.9%]) compared with No-MI (0.7% [95% CI, 0.1%-1.3%]; odds ratio, 3.71 [95% CI, 0.58-23.61], P=0.09).CONCLUSIONS: In the largest contemporary MINOCA meta-analysis to date, patients with suspected MINOCA had a favorable prognosis compared with MI-CAD, but statistically nonsignificant trend toward worse outcomes compared to those with No-MI.
