Digoxin was significantly associated with all-cause, cardiac, and arrhythmic death, with estimated hazard ratios (HR) of 1.39 (95% confidence interval [CI] 1.11-1.73, P = 0.004), 1.44 (95% CI 1.13-1.82, P = 0.003), and 2.03 (95% CI 1.63-2.54, P  less then  0.0001), respectively. Digoxin was not associated with cardiovascular hospitalizations [HR 1.12 (95% CI 0.91-1.37), P = 0.29]. CONCLUSION Digoxin is associated with increased all-cause mortality among patients with combined heart failure with reduced ejection fraction and AF, which is predominantly driven by arrhythmic deaths. In contrast, cardiovascular hospitalizations were not impacted by digoxin. BACKGROUND Cardiovascular magnetic resonance T1 mapping is a non-invasive tool for quantifying tissue alterations in the myocardium. Its prognostic value in non-ischemic dilated cardiomyopathy (DCM) remains unclear. The purpose of this study was to synthetize available data and explore the prognostic value of T1 mapping in DCM. METHODS We searched Pubmed, Embase, Cochrane Library and Scopus for cohort studies up to 28 March 2020 that reported prognostic data for cardiovascular magnetic resonance T1 mapping in patients with DCM. Hazard ratios (HRs) were pooled using random-effects meta-analysis. Values were expressed as standard deviation (SD) of normal controls. Heterogeneity was assessed with the I2 statistic. RESULTS Eight studies were included in the meta-analysis, with a total of 1242 patients. Extracellular volume fraction (ECV) had high prognostic value for a composite outcome of mortality and morbidity with HR 1.38 (95% confidence interval, 1.18-1.61). Native T1 was also shown to have high prognostic value for a composite outcome of mortality and morbidity with HR 1.20 (95% confidence interval, 1.14-1.27). Heterogeneity was moderate for the ECV analysis (I2 = 64%). CONCLUSIONS ECV and native T1 could potentially be used to improve risk stratification in DCM. Future studies should investigate the prognostic value of T1 mapping by separating mortality and morbidity as primary outcomes and evaluate its incremental value in addition to standard risk stratification criteria. BACKGROUND The benefits of invasive versus noninvasive management in oncology patients with acute myocardial infarction (AMI) are unclear. We aimed to retrospectively determine outcome differences between conservative and invasive management of AMI in cancer patients. METHODS Patients from our institution between March 2016 and December 2018 with type 1 and type 2 AMI (excluding STEMI) were classified into 2 groups medical therapy only and invasive strategies. Analyzed outcomes were overall survival (OS), procedural complications, subsequent events, and hospice referral. Kaplan-Meier method and log-rank test were used to compare OS between subgroups. Cox proportional hazards regression analyses were conducted to find factors associated with OS. RESULTS We included 201 patients. Type 1 MI was seen in 152 patients (76%) and type 2 MI in 49 (24%). Median OS was 13 months. Most presented with symptoms other than dyspnea or chest pain (49%) and with ECG revealing changes other than ST-segment depression and T-wave inversion (62%). Patients with type 2 MI had worse OS than patients with type 1 MI (HR = 2.3, p = 0.0002). Early coronary angiography (≤72 h; HR = 0.327, p 72 h; HR = 0.496, p = 0.0426), and percutaneous coronary intervention (HR = 0.481, p = 0.0116) were associated with better OS than noninvasive approaches. Single and dual agent antiplatelet therapy, beta blockers, and statins were each associated with better OS. CONCLUSIONS Cancer patients without STEMI who underwent invasive treatment for AMI had better OS compared with those treated only medically, with the highest benefit when coronary angiography was performed within 72 h of admission for AMI. BACKGROUND Up to two-thirds of patients with obstructive coronary artery disease (CAD) have silent ischemia (SI), which predicts an adverse prognosis and can be a treatment target in obstructive CAD. Over 50% of women with ischemia and no obstructive CAD have coronary microvascular dysfunction (CMD), which is associated with adverse cardiovascular outcomes. We aimed to investigate the prevalence of SI in CMD in order to consider it as a potential treatment target. METHODS 36 women with CMD by coronary reactivity testing and 16 age matched reference subjects underwent 24-h 12-lead ambulatory ECG monitoring (Mortara Instruments) after anti-ischemia medication withdrawal. Ambulatory ECG recordings were reviewed by two-physician consensus masked to subject status for SI measured by evidence of ≥1 minute horizontal or downsloping ST segment depression ≥1.0 mm, measured 80 ms from the J point. RESULTS Demographics, resting heart rate, and systolic blood pressure were similar between CMD and reference subjects. Thirty-nine percent of CMD women had a total of 26 SI episodes vs. 0 episodes in the reference group (p = 0.002). Among these women 13/14 (93%) had SI, and few episodes (3/26, 12%) were symptomatic. Mean HR at the onset of SI was 96 ± 13 bpm and increased to 117 ± 16 bpm during the ischemic episodes. 87% reported symptoms that were not associated with ST depressions. MI-773 CONCLUSIONS Ambulatory ischemia is prevalent in women with CMD, with a majority being SI, while most reported symptoms were not accompanied by ambulatory ischemia. Clinical trials evaluating anti-ischemic medications should be considered in the CMD population. V.Frailty is a syndrome characterized by reduced physiological reserves, increased vulnerability to stressors and adverse health outcomes. Frailty can change the prognosis and treatment approach of several chronic diseases, including heart failure (HF). The aim of this study was to conduct a systematic review and meta-analysis assessing the association of HF with frailty and pre-frailty. We employed PRISMA guidelines for reporting the results. We searched PubMed, Web of Science, and Embase from 01/01/2002 to 29/11/2019.The quality of the studies was evaluated with the Newcastle Ottawa Scale. Pooled estimates were obtained through random-effect models and Mantel-Haenszel weighting. Homogeneity (I2) and publication bias were assessed. We selected 54 studies (52 cross-sectional, one longitudinal, and one with both designs). The pooled prevalence of pre-frailty in individuals with HF was 46% (95% CI = 38-53; I2 = 93.1%) and 40% (95% CI = 31-48; I2 = 97%) for frailty. The proportion of pre-frail individuals with HF was 20% (95%CI = 15-25; I2 = 99.
