At the beginning of June 2020, there were nearly 7 million reported cases of coronavirus disease 2019 (COVID-19) worldwide and over 400,000 deaths in people with COVID-19. The objective of this study ...was to determine associations between comorbidities listed in the Charlson comorbidity index and mortality among patients in the United States with COVID-19.
A retrospective cohort study of adults with COVID-19 from 24 healthcare organizations in the US was conducted. The study included adults aged 18-90 years with COVID-19 coded in their electronic medical records between January 20, 2020, and May 26, 2020. Results were also stratified by age groups (<50 years, 50-69 years, or 70-90 years). A total of 31,461 patients were included. Median age was 50 years (interquartile range IQR, 35-63) and 54.5% (n = 17,155) were female. The most common comorbidities listed in the Charlson comorbidity index were chronic pulmonary disease (17.5%, n = 5,513) and diabetes mellitus (15.0%, n = 4,710). Multivariate logistic regression analyses showed older age (odds ratio OR per year 1.06; 95% confidence interval CI 1.06-1.07; p < 0.001), male sex (OR 1.75; 95% CI 1.55-1.98; p < 0.001), being black or African American compared to white (OR 1.50; 95% CI 1.31-1.71; p < 0.001), myocardial infarction (OR 1.97; 95% CI 1.64-2.35; p < 0.001), congestive heart failure (OR 1.42; 95% CI 1.21-1.67; p < 0.001), dementia (OR 1.29; 95% CI 1.07-1.56; p = 0.008), chronic pulmonary disease (OR 1.24; 95% CI 1.08-1.43; p = 0.003), mild liver disease (OR 1.26; 95% CI 1.00-1.59; p = 0.046), moderate/severe liver disease (OR 2.62; 95% CI 1.53-4.47; p < 0.001), renal disease (OR 2.13; 95% CI 1.84-2.46; p < 0.001), and metastatic solid tumor (OR 1.70; 95% CI 1.19-2.43; p = 0.004) were associated with higher odds of mortality with COVID-19. Older age, male sex, and being black or African American (compared to being white) remained significantly associated with higher odds of death in age-stratified analyses. There were differences in which comorbidities were significantly associated with mortality between age groups. Limitations include that the data were collected from the healthcare organization electronic medical record databases and some comorbidities may be underreported and ethnicity was unknown for 24% of participants. Deaths during an inpatient or outpatient visit at the participating healthcare organizations were recorded; however, deaths occurring outside of the hospital setting are not well captured.
Identifying patient characteristics and conditions associated with mortality with COVID-19 is important for hypothesis generating for clinical trials and to develop targeted intervention strategies.

Mobile Health technology for the management of patients with atrial fibrillation is unknown.
The simple mobile AF (mAF) App was designed to incorporate clinical decision-support tools (CHA2DS2-VASc ...Congestive heart failure, Hypertension, Age ≥75 years, Diabetes Mellitus, Prior Stroke or TIA, Vascular disease, Age 65–74 years, Sex category, HAS-BLED Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile INR, Elderly, Drugs/alcohol concomitantly, SAMe-TT2R2 Sex, Age <60 years, Medical history, Treatment, Tobacco use, Race scores), educational materials, and patient involvement strategies with self-care protocols and structured follow-up. Patients with atrial fibrillation were randomized into 2 groups (mAF App vs usual care) in a cluster randomized design pilot study. Patients' knowledge, quality of life, drug adherence, and anticoagulation satisfaction were evaluated at baseline, 1 month, and 3 months. Usability, feasibility, and acceptability of the mAF App were assessed at 1 month.
A total of 113 patients were randomized to mAF App intervention (mean age, 67.4 years; 57.5% were male; mean follow-up, 69 days), and 96 patients were randomized to usual care (mean age, 70.9 years; 55.2% were male; mean follow-up, 95 days). More than 90% of patients reported that the mAF App was easy, user-friendly, helpful, and associated with significant improvements in knowledge compared with the usual care arm (P values for trend <.05). Drug adherence and anticoagulant satisfaction were significantly better with the mAF App versus usual care (all P < .05). Quality of life scores were significantly increased in the mAF App arm versus usual care, with anxiety and depression reduced (all P < .05).
The pilot mAFA Trial is the first prospective randomized trial of Mobile Health technology in patients with atrial fibrillation, demonstrating that the mAF App, integrating clinical decision support, education, and patient-involvement strategies, significantly improved knowledge, drug adherence, quality of life, and anticoagulation satisfaction.
Depression and anxiety are highly prevalent in patients with cardiovascular disease (CVD) and influence their mental well-being and CVD prognosis. The primary objective was to assess the ...effectiveness of cognitive behavioral therapy (CBT) for depression and anxiety in patients with CVD. Secondary objectives were to assess the impact of CBT on cardiovascular mortality, cardiovascular events, patient satisfaction, and quality of life.
MEDLINE, PsycINFO, CINAHL, CENTRAL, and alternative sources were searched for randomized controlled trials and observational studies with a control. Studies were required to assess CBT in coronary heart disease, acute coronary syndrome, atrial fibrillation, or postmyocardial infarction patients, with anxiety and/or depression. Studies were independently screened by two reviewers and critically appraised using the Cochrane Risk of Bias tool. The random-effects model was used to pool standardized mean differences (SMD).
Twelve randomized controlled trials were included. At follow-up, depression (SMD = -0.35, 95% confidence interval CI = -0.52 to -0.17, p < .001, I = 59%) and anxiety (SMD = -0.34, 95% CI = -0.65 to -0.03, p = .03, I = 71%) scores were significantly lower in CBT patients compared with controls. Change in mental health quality of life (SF-12) was also significantly greater for CBT patients, compared with controls (mean difference = 3.62, 95% CI = 0.22 to 7.02, p = .04, I = 0%). No differences in patient satisfaction or cardiovascular events were evident between CBT and control groups. Among the study reports included in this meta-analysis, data specific to cardiovascular mortality were not reported.
Cognitive behavioral therapy seems to be an effective treatment for reducing depression and anxiety in patients with CVD and should be considered in standard clinical care.
Objective To clarify the impact of digoxin on death and clinical outcomes across all observational and randomised controlled trials, accounting for study designs and methods.Data sources and study ...selection Comprehensive literature search of Medline, Embase, the Cochrane Library, reference lists, and ongoing studies according to a prospectively registered design (PROSPERO: CRD42014010783), including all studies published from 1960 to July 2014 that examined treatment with digoxin compared with control (placebo or no treatment).Data extraction and synthesis Unadjusted and adjusted data pooled according to study design, analysis method, and risk of bias.Main outcome measures Primary outcome (all cause mortality) and secondary outcomes (including admission to hospital) were meta-analysed with random effects modelling.Results 52 studies were systematically reviewed, comprising 621 845 patients. Digoxin users were 2.4 years older than control (weighted difference 95% confidence interval 1.3 to 3.6), with lower ejection fraction (33% v 42%), more diabetes, and greater use of diuretics and anti-arrhythmic drugs. Meta-analysis included 75 study analyses, with a combined total of 4 006 210 patient years of follow-up. Compared with control, the pooled risk ratio for death with digoxin was 1.76 in unadjusted analyses (1.57 to 1.97), 1.61 in adjusted analyses (1.31 to 1.97), 1.18 in propensity matched studies (1.09 to 1.26), and 0.99 in randomised controlled trials (0.93 to 1.05). Meta-regression confirmed that baseline differences between treatment groups had a significant impact on mortality associated with digoxin, including markers of heart failure severity such as use of diuretics (P=0.004). Studies with better methods and lower risk of bias were more likely to report a neutral association of digoxin with mortality (P<0.001). Across all study types, digoxin led to a small but significant reduction in all cause hospital admission (risk ratio 0.92, 0.89 to 0.95; P<0.001; n=29 525).Conclusions Digoxin is associated with a neutral effect on mortality in randomised trials and a lower rate of admissions to hospital across all study types. Regardless of statistical analysis, prescription biases limit the value of observational data.

Abstract Background Atrial fibrillation (AF) and heart failure frequently coexist, commonly resulting in serious adverse events. With both conditions increasing in prevalence and justified concerns ...about treatment efficacy, it is vital to understand how the type of heart failure impacts on prognosis. Methods We performed a systematic review of studies examining cardiovascular outcomes in AF patients with heart failure and reduced ejection fraction (AF-HFrEF) compared to those with preserved ejection fraction (AF-HFpEF). The primary outcome was all-cause mortality, meta-analyzed using a random-effects model. Prospective registration: PROSPERO-CRD42014007305. Results Thirteen studies were included in the systematic review (n = 54,587) with 10 suitable for meta-analysis, including retrospective/prospective cohorts and sub-group analyses of randomized trials. AF-HFrEF was present in 49% and these patients were younger, more often male and with higher NYHA class than AF-HFpEF. Oral anticoagulation use was 55% versus 50% respectively (p < 0.001). All-cause mortality was significantly higher in AF-HFrEF; risk ratio (RR) 1.24, 95% CI 1.12–1.36, p < 0.001 (n = 45,100), with absolute death rates of 24% compared to 18% in AF-HFpEF over 2 years. There were no significant differences in incident stroke (RR 0.85, 95% CI 0.70–1.03, p = 0.094; n = 33,773) or heart failure hospitalization (RR 1.21, 95% CI 0.96–1.53, p = 0.115; n = 31,583). The risk of bias was generally low, but heterogeneity was substantial. Conclusions All-cause mortality is significantly higher in AF patients with HFrEF compared to HFpEF, although stroke risk and heart failure hospitalization are similar. Further studies are needed to address the prevention of adverse outcomes in all AF patients with heart failure, regardless of ejection fraction.

There is limited evidence for the efficacy of cognitive behavioral therapy (CBT) in managing psychological morbidities in caregivers of dementia patients. To evaluate changes in dementia caregivers' ...depression, anxiety, and stress following CBT. Also to assess quality of life, intervention adherence/satisfaction and therapy effectiveness using different formats, frequencies, and delivery methods.
Studies were identified through electronic bibliographic searches (MEDLINE, EMBASE, CINAHL, PsycINFO, and the Cochrane Library) and from gray literature (Conference Proceedings Citation Index and clinicaltrials.gov). Data were pooled for meta-analysis.
Twenty-five studies were included. Depression (standardized mean difference SMD = -0.34; 95% confidence interval CI -0.47 to -0.21; p < .001) and stress (SMD = -0.36; 95% CI: -0.52 to -0.20; p < .001) were significantly reduced after CBT, relative to comparator groups, while anxiety was not (SMD = 0.10; 95% CI: -0.18 to 0.39; p = .47). A subgroup analysis demonstrated that statistically significant reductions in depression and stress were limited to group, but not individual, formats. An additional subgroup analysis revealed that eight CBT sessions or fewer were equally effective as more than eight sessions at significantly reducing depression and stress, relative to comparator groups. Furthermore, analysis with independent samples t-tests demonstrated no statistically significant differences between mean changes in depression (MD = 0.79; 95% CI: -0.45 to 2.03; p = .21) and stress (MD = 0.21; 95% CI: -1.43 to 1.85; p = .80) when directly comparing CBT groups of ≤8 and >8 sessions.
Group CBT provides small but significant benefits to caregivers' depression and stress. Therapy cost-effectiveness may be improved by limiting therapy to group formats and eight sessions.
The risk of stroke is heterogeneous across different groups of patients with atrial fibrillation (AF), being dependent on the presence of various stroke risk factors. We provide recommendations for ...antithrombotic treatment based on net clinical benefit for patients with AF at varying levels of stroke risk and in a number of common clinical scenarios.
Systematic literature reviews were conducted to identify relevant articles published from the last formal search perfomed for the Antithrombotic and Thrombolytic Therapy: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines (9th Edition). The overall quality of the evidence was assessed using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. Graded recommendations and ungraded consensus-based statements were drafted, voted on, and revised until consensus was reached.
For patients with AF without valvular heart disease, including those with paroxysmal AF, who are at low risk of stroke (eg, CHA
DS
-VASc congestive heart failure, hypertension, age ≥ 75 (doubled), diabetes, stroke (doubled)-vascular disease, age 65-74 and sex category (female) score of 0 in males or 1 in females), we suggest no antithrombotic therapy. The next step is to consider stroke prevention (ie, oral anticoagulation therapy) for patients with 1 or more non-sex CHA
DS
-VASc stroke risk factors. For patients with a single non-sex CHA
DS
-VASc stroke risk factor, we suggest oral anticoagulation rather than no therapy, aspirin, or combination therapy with aspirin and clopidogrel; and for those at high risk of stroke (eg, CHA
DS
-VASc ≥ 2 in males or ≥ 3 in females), we recommend oral anticoagulation rather than no therapy, aspirin, or combination therapy with aspirin and clopidogrel. Where we recommend or suggest in favor of oral anticoagulation, we suggest using a non-vitamin K antagonist oral anticoagulant drug rather than adjusted-dose vitamin K antagonist therapy. With the latter, it is important to aim for good quality anticoagulation control with a time in therapeutic range > 70%. Attention to modifiable bleeding risk factors (eg, uncontrolled BP, labile international normalized ratios, concomitant use of aspirin or nonsteroidal antiinflammatory drugs in an anticoagulated patient, alcohol excess) should be made at each patient contact, and HAS-BLED (hypertension, abnormal renal/liver function 1 point each, stroke, bleeding history or predisposition, labile international normalized ratio, elderly (0.65), drugs/alcohol concomitantly 1 point each) score used to assess the risk of bleeding where high risk patients (≥ 3) should be reviewed and followed up more frequently.
Oral anticoagulation is the optimal choice of antithrombotic therapy for patients with AF with ≥1 non-sex CHA
DS
-VASc stroke risk factor(s).

Integrated care for the clinical management of atrial fibrillation patients is advocated as a holistic way to improve outcomes; the simple Atrial fibrillation Better Care (ABC) pathway has been ...proposed. The ABC pathway streamlines care as follows: ‘A’ Avoid stroke; ‘B’ Better symptom management; ‘C’ Cardiovascular and Comorbidity optimization.
We performed a post hoc analysis of the Atrial Fibrillation Follow-Up Investigation of Rhythm Management (AFFIRM) trial. An ‘integrated care’ approach was defined according to the ABC pathway. Patients fulfilling all criteria were categorized as the ‘ABC’ group; those not fulfilling all criteria were the ‘non-ABC’ group. Trial-adjudicated all-cause death, composite outcome of stroke/major bleeding/cardiovascular death, and first hospitalization were the main study outcomes.
Among the 4060 patients in the original cohort, 3169 (78%) had available data to compare integrated care (ABC; n = 222; 7%) vs non-ABC (n = 2947; 93%) management. Over a median follow-up of 3.7 (interquartile range, 2.8-4.6) years, atrial fibrillation patients managed with integrated care (ABC group) had lower rates for all study outcomes (all P < .001) compared with the non-ABC group. A Cox multivariable regression analysis showed that atrial fibrillation patients managed in the ABC group had a significantly lower risk of all-cause death (hazard ratio HR, 0.35; 95% confidence interval CI, 0.17-0.75), composite outcome (HR, 0.35; 95% CI, 0.18-0.68), and first hospitalization (HR, 0.65; 95% CI, 0.53-0.80).
The simple ABC pathway allows the streamlining of integrated care for atrial fibrillation patients in a holistic manner and is associated with a lower risk of adverse outcomes (including mortality, stroke/major bleeding/cardiovascular death, and hospitalization).
