Invasive Treatment Strategy in Adults With Frailty and Non-ST-Segment Elevation Myocardial Infarction: A Secondary Analysis of a Randomized Clinical Trial

Importance

The MOSCA-FRAIL randomized clinical trial compared invasive and conservative treatment strategies in patients with frailty with non-ST-segment elevation myocardial infarction (NSTEMI). It showed no differences in the number of days alive and out of the hospital at 1 year.

Objective

To assess the outcomes of the MOSCA-FRAIL trial during extended follow-up.

Design, Setting, and Participants

The MOSCA-FRAIL randomized clinical trial was conducted at 13 hospitals in Spain between July 7, 2017, and January 9, 2021, and included 167 adults (aged ≥70 years) with frailty (Clinical Frailty Scale score ≥4) and NSTEMI. In this preplanned secondary analysis, follow-up was extended to January 31, 2023. Data analysis was performed from April 5 to 29, 2023, using the intention-to-treat principle.

Interventions

Patients were randomized to a routine invasive (coronary angiography and revascularization if feasible [n = 84]) or a conservative (medical treatment with coronary angiography only if recurrent ischemia [n = 83]) strategy.

Main outcomes and measures

The primary end point was the difference in restricted mean survival time (RMST). Secondary end points included readmissions for any cause, considering recurrent readmissions.

Results

Among the 167 patients included in the analysis, the mean (SD) age was 86 (5) years; 79 (47.3%) were men and 88 (52.7%) were women. A total of 93 deaths and 367 readmissions accrued. The RMST for all-cause death over the entire follow-up was 3.13 (95% CI, 2.72-3.60) years in the invasive and 3.06 (95% CI, 2.84-3.32) years in the conservative treatment groups. The RMST analysis showed inconclusive differences in survival time (invasive minus conservative difference, 28 [95% CI, -188 to 230] days). Patients under invasive treatment tended to have shorter survival in the first year (-28 [95% CI, -63 to 7] days), which improved after the first year (192 [95% CI, 90-230] days). Kaplan-Meier mortality curves intersected, displaying higher mortality to 1 year in the invasive group that shifted to a late benefit (landmark analysis hazard ratio, 0.58 [95% CI, 0.33-0.99]; P = .045). Early harm was more evident in the subgroup with a Clinical Frailty Scale score greater than 4. No differences were found for the secondary end points.

Conclusions and Relevance

In this extended follow-up of a randomized clinical trial of patients with frailty and NSTEMI, an invasive treatment strategy did not improve outcomes at a median follow-up of 1113 (IQR, 443-1441) days. However, a differential distribution of deaths was observed, with early harm followed by later benefit. The phenomenon of depletion of susceptible patients may be responsible for this behavior.

Association between subclinical atherosclerosis burden and unrecognized myocardial infarction detected by cardiac magnetic resonance in middle-aged adults

AIMS

Evidence on the association between subclinical atherosclerosis (SA) and cardiovascular (CV) events in low-risk populations is scant. To study the association between SA burden and an ischemic scar (IS), identified by cardiac magnetic resonance (CMR), as a surrogate of CV endpoint, in a low-risk population.

METHODS

A cohort of 712 asymptomatic middle-aged individuals from the Progression of Early SA (PESA-CNIC-Santander) study (median age 51 years, 84% male, median SCORE2 3.37) were evaluated on enrollment and at 3-year follow-up with 2D/3D vascular ultrasound (VUS) and coronary artery calcification scoring (CACS). A cardiac magnetic study (CMR) was subsequently performed, and IS defined as the presence of subendocardial or transmural late gadolinium enhancement (LGE).

RESULTS

On CMR, 132 (19.1%) participants had positive LGE, and IS was identified in 20 (2.9%) participants. Individuals with IS had significantly higher SCORE2 at baseline and higher CACS and peripheral SA burden (number of plaques by 2DVUS and plaque volume by 3DVUS) at both SA evaluations. High CACS and peripheral SA (number of plaques) burden were independently associated with the presence of IS, after adjusting for SCORE2 (OR for 3rd tertile, 8.31; 95% CI 2.85-24.2; p<0.001; and 2.77; 95% CI, 1.02-7.51; p=0.045, respectively) and provided significant incremental diagnostic value over SCORE2.

CONCLUSIONS

In a low-risk middle-aged population, SA burden (CAC and peripheral plaques) was independently associated with a higher prevalence of IS identified by CMR. These findings reinforce the value of SA evaluation to early implement preventive measures.

Sex differences in population versus in-hospital use of aortic valve replacement procedures in Spain

BACKGROUND AND AIMS

It is not well known if sex differences in the use and results of aortic valve replacement (AVR) are changing. The aim of the study is to assess the time trends in the differences by sex in the utilisation of AVR procedures in hospitals and in the community.

METHODS

Retrospective observational analysis using data from the Spanish National Hospitalizations Administrative Database. All hospitalisations between 2016 and 2021 with a main diagnosis of aortic stenosis (ICD-10 codes: I35.0 and I35.2) were included. Time trends in hospitalisation, AVRs and hospital outcomes were analysed. Crude utilisation and population-standardised rates were calculated.

RESULTS

During the study period, 64 384 hospitalisations in 55 983 patients (55.5% men) with 36 915 (65,9%) AVR were recorded. Of these, 15 563 (42.2%) were transcatheter and 21 432 (58.0%) surgical. At hospital level, transcatheter procedures were more frequently performed in women (32.3% vs 24.2%, p < 0.001) and surgical in men (42.9% vs. 32.5%, p < 0.001) but at the population level, surgical and transcatheter aortic valve replacements were used more frequently in men (12.6 surgical and 8.0 transcatheter per 100 000 population) vs women (6.4 and 5.8, respectively; p < 0.001 for both comparisons). Transcatheter procedures shifted from 17.3% in 2016 to 38.0% in 2021, overtaking surgical procedures in 2018 for women and 2021 for men.

CONCLUSIONS

TAVR has displaced SAVR as the most frequent AVR procedure in Spain by 2020. This occurred earlier in women, who despite the greater weight of their age group in the older population, receive fewer AVRs, both SAVR and TAVR.

Robustness of [18F]FDG PET/CT radiomic analysis in the setting of drug-induced cardiotoxicity

BACKGROUND AND OBJECTIVES

Standardization of radiomic data acquisition protocols is still at a very early stage, revealing a strong need to work towards the definition of uniform image processing methodologies The aim of this study is to identify sources of variability in radiomic data derived from image discretization and resampling methodologies prior to image feature extraction. Furthermore, to identify robust potential image-based biomarkers for the early detection of cardiotoxicity.

METHODS

Image post-acquisition processing, interpolation, and volume of interest (VOI) segmentation were performed. Four experiments were conducted to assess the reliability in terms of the intraclass correlation coefficient (ICC) of the radiomic features and the effects of the variation of voxel size and gray level discretization. Statistical analysis was performed separating the patients according to cardiotoxicity diagnosis. Differences of texture features were studied with Mann-Whitney U test. P-values <0.05 after multiple testing correction were considered statistically significant. Additionally, a non-supervised k-Means clustering algorithm was evaluated.

RESULTS

The effect of the variation in the voxel size demonstrated a non-dependency relationship with the values of the radiomic features, regardless of the chosen discretization method. The median ICC values were 0.306 and 0.872 for absolute agreement and consistency, respectively, when varying the discretization bin number. The median ICC values were 0.678 and 0.878 for absolute agreement and consistency, respectively, when varying the discretization bin size. A total of 16 first order, 6 Gray Level Co-occurrence Matrix (GLCM), 4 Gray Level Dependence Matrix (GLDM) and 4 Gray Level Run Length Matrix (GLRLM) features demonstrated statistically significant differences between the diagnosis groups for interim scans (P<0.05) for the fixed bin size (FBS) discretization methodology. However, no statistically significant differences between diagnostic groups were found for the fixed bin number (FBN) discretization methodology. Two clusters based on the radiomic features were identified.

CONCLUSIONS

Gray level discretization has a major impact on the repeatability of the radiomic features. The selection of the optimal processing methodology has led to the identification of texture-based patterns for the differentiation of early cardiac damage profiles.

Secondary Prevention Therapies in Real-World Patients with Myocardial Infarction: Eligibility Based on Randomized Trials Supporting European and American Guidelines

OBJECTIVE

We aimed to evaluate the applicability of the eligibility criteria of randomized controlled trials (RCTs) cited in guideline recommendations in a real-world cohort of patients receiving secondary prevention after acute myocardial infarction from the EPICOR registries.

METHODS

Recommendations provided by American and European guidelines for acute myocardial infarction were classified into general (applying to all patients) and specific (applying to patients with left ventricular dysfunction or heart failure). Randomized controlled trials cited in these recommendations were selected, and their entry criteria were applied to our international cohort of 18,117 patients.

RESULTS

There were 91.5% patients eligible for beta blockers (84.6% for general, and 5.9% for specific recommendations), 97.7% eligible for renin-angiotensin system inhibitor (angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers [ACEI/ARB]) recommendations (69.9% for general, 27.9% for specific) and 4.1% eligible for mineralocorticoid receptor antagonists (only specific recommendations). The percentages of patients with eligibility criteria who were discharged with a prescription of the recommended therapies were 80%-85% for beta blockers, 70%-75% for ACEI/ARB, and 29% for mineralocorticoid receptor antagonists. There were large regional variations in the percentage of eligible patients and in those receiving the medications (eg, 95% in Northern Europe and 57% in Southeast Asia for beta blockers).

CONCLUSION

Most real-world acute myocardial infarction patients are eligible for secondary prevention therapy in both general and specific guideline recommendations, and the percentage of those on beta blockers and ACEI/ARB at hospital discharge is high. There are large regional variations in the proportion of patients receiving recommended therapies. Local targeted interventions are needed for quality improvement.

Impact of the MEESSI-AHF tool to guide disposition decision-making in patients with acute heart failure in the emergency department: a before-and-after study

OBJECTIVES

To determine the impact of risk stratification using the MEESSI-AHF (Multiple Estimation of risk based on the Emergency department Spanish Score In patients with acute heart failure) scale to guide disposition decision-making on the outcomes of ED patients with acute heart failure (AHF), and assess the adherence of emergency physicians to risk stratification recommendations.

METHODS

This was a prospective quasi-experimental study (before/after design) conducted in eight Spanish EDs which consecutively enrolled adult patients with AHF. In the pre-implementation stage, the admit/discharge decision was performed entirely based on emergency physician judgement. During the post-implementation phase, emergency physicians were advised to 'discharge' patients classified by the MEESSI-AHF scale as low risk and 'admit' patients classified as increased risk. Nonetheless, the final decision was left to treating emergency physicians. The primary outcome was 30-day all-cause mortality. Secondary outcomes were days alive and out of hospital, in-hospital mortality and 30-day post-discharge combined adverse event (ED revisit, hospitalisation or death).

RESULTS

The pre-implementation and post-implementation cohorts included 1589 and 1575 patients, respectively (median age 85 years, 56% females) with similar characteristics, and 30-day all-cause mortality was 9.4% and 9.7%, respectively (post-implementation HR=1.03, 95% CI=0.82 to 1.29). There were no differences in secondary outcomes or in the percentage of patients entirely managed in the ED without hospitalisation (direct discharge from the ED, 23.5% vs 24.4%, OR=1.05, 95% CI=0.89 to 1.24). Adjusted models did not change these results. Emergency physicians followed the MEESSI-AHF-based recommendation on patient disposition in 70.9% of cases (recommendation over-ruling: 29.1%). Physicians were more likely to over-rule the recommendation when 'discharge' was recommended (56.4%; main reason: need for hospitalisation for a second diagnosis) than when 'admit' was recommended (12.8%; main reason: no appreciation of severity of AHF decompensation by emergency physician), with an OR for over-ruling the 'discharge' compared with the 'admit' recommendation of 8.78 (95% CI=6.84 to 11.3).

CONCLUSIONS

Implementing the MEESSI-AHF risk stratification tool in the ED to guide disposition decision-making did not improve patient outcomes.

Differences in clinical outcomes, health care resource utilization and costs in heart failure patients according to left ventricular ejection fraction

INTRODUCTION AND OBJECTIVES

The impact of left ventricular ejection fraction (LVEF) on health care resource utilization (HCRU) and cost in heart failure (HF) patients is not well known. We aimed to compare outcomes, HCRUs and costs according to LVEF groups.

METHODS

Retrospective, observational study of all patients with an emergency department (ED) visit or admission to a tertiary hospital in Spain 2018 with a primary HF diagnosis. We excluded patients with newly diagnosed heart failure. One-year clinical outcomes, costs and HCRUs were compared according to LVEF (reduced [HFrEF], mildly reduced [HFmrEF], and preserved [HFpEF]).

RESULTS

Among 1287 patients with a primary diagnosis of HF in the ED, 365 (28.4%) were discharged to home (ED group), and 919 (71.4%) were hospitalized (hospital group [HG]). In total, 190 patients (14.7%) had HFrEF, 146 (11.4%) HFmrEF, and 951 (73.9%) HFpEF. The mean age was 80.1±10.7 years; 57.1% were female. The median [interquartile range] of costs per patient/y was €1889 [259-6269] in the ED group and €5008 [2747-9589] in the HG (P <.001). Hospitalization rates were higher in patients with HFrEF in the ED group. The median costs of HFrEF per patient/y were higher in patients in both groups: €4763 [2076-17 155] vs €3900 [590-8013] for HFmrEF vs €3812 [259-5486] for HFpEF in the ED group, and €6321 [3335-796] vs €6170 [3189-10484] vs €4636 [2609-8977], respectively, in the hospital group (all P <.001). This difference was driven by the more frequent admission to intensive care units, and greater use of diagnostic and therapeutic tests among HFrEF patients.

CONCLUSIONS

In HF, LVEF significantly impacts costs and HCRU. Costs were higher in patients with HFrEF, especially those requiring hospitalization, than in those with HFpEF.

Cardiac Insulin Resistance in Subjects With Metabolic Syndrome Traits and Early Subclinical Atherosclerosis

OBJECTIVE

Experimental evidence suggests that metabolic syndrome (MetS) is associated with changes in cardiac metabolism. Whether this association occurs in humans is unknown.

RESEARCH DESIGN AND METHODS

821 asymptomatic individuals from the Progression of Early Subclinical Atherosclerosis (PESA) study (50.6 [46.9-53.6] years, 83.7% male) underwent two whole-body 18F-fluorodeoxyglucose positron emission tomography-magnetic resonance (18F-FDG PET-MR) 4.8 ± 0.6 years apart. Presence of myocardial 18F-FDG uptake was evaluated qualitatively and quantitatively. No myocardial uptake was grade 0, while positive uptake was classified in grades 1-3 according to target-to-background ratio tertiles.

RESULTS

One hundred fifty-six participants (19.0%) showed no myocardial 18F-FDG uptake, and this was significantly associated with higher prevalence of MetS (29.0% vs. 13.9%, P < 0.001), hypertension (29.0% vs. 18.0%, P = 0.002), and diabetes (11.0% vs. 3.2%, P < 0.001), and with higher insulin resistance index (HOMA-IR, 1.64% vs. 1.23%, P < 0.001). Absence of myocardial uptake was associated with higher prevalence of early atherosclerosis (i.e., arterial 18F-FDG uptake, P = 0.004). On follow-up, the associations between myocardial 18F-FDG uptake and risk factors were replicated, and MetS was more frequent in the group without myocardial uptake. The increase in HOMA-IR was associated with a progressive decrease in myocardial uptake (P < 0.001). In 82% of subjects, the categorization according to presence/absence of myocardial 18F-FDG uptake did not change between baseline and follow-up. MetS regression on follow-up was associated with a significant (P < 0.001) increase in myocardial uptake.

CONCLUSIONS

Apparently healthy individuals without cardiac 18F-FDG uptake have higher HOMA-IR and higher prevalence of MetS traits, cardiovascular risk factors, and early atherosclerosis. An improvement in cardiometabolic profile is associated with the recovery of myocardial 18F-FDG uptake at follow-up.

Impact of standard modifiable cardiovascular risk factors on 2-year all-cause mortality: Insights from an international cohort of 23,489 patients with acute coronary syndrome

BACKGROUND

Controversial findings have been reported in the literature regarding the impact of the absence of standard modifiable cardiovascular risk factors (SMuRFs) on long-term mortality risk in patients with acute coronary syndrome (ACS). While the prognostic additive value of SMuRFs has been well described, the prognostic role of prior cardiovascular disease (CVD) by sex is less well-known in patients with and without SMuRFs.

METHODS

EPICOR and EPICOR Asia are prospective, observational registries conducted between 2010 and 2014, which enrolled ACS patients in 28 countries across Europe, Latin America, and Asia. Association between SMuRFs (diabetes, dyslipidaemia, hypertension, and smoking) and 2-year postdischarge mortality was evaluated using adjusted Cox models stratified by geographical region.

RESULTS

Among 23,489 patients, the mean age was 60.9 ± 11.9 years, 24.3% were women, 4,582 (20.1%) presented without SMuRFs, and 16,055 (69.5%) without prior CVD. Patients with SMuRFs had a higher crude 2-year postdischarge mortality (HR 1.86; 95% CI, 1.56-2.22; P < .001), compared to those without SMuRFs. After adjustment for potential confounding, the association between SMuRFs and 2-year mortality risk was substantially attenuated (HR 1.17, 95% CI 0.98-1.41; P = .087), regardless of the type of ACS. The risk conferred by prior CVD was added to the underlying risk of SMuRFs to provide risk-specific phenotypes (eg, women with SMuRFs and with prior CVD were at higher risk of dying than women without SMuRFs and without CVD; HR 1.67, 95% CI 1.34-2.06).

CONCLUSIONS

In this large-scale international ACS cohort the absence of SMuRFs was not associated with a lower adjusted 2-year postdischarge mortality risk. Patients with both SMuRFs and prior CVD had a higher mortality irrespective of their sex.

Sex-Specific Associations of Obstructive Sleep Apnea Risk With Patient Characteristics and Functional Outcomes After Acute Myocardial Infarction: Evidence From the VIRGO Study

Background Though associations between obstructive sleep apnea (OSA) and cardiovascular outcomes are well described, limited data exist regarding the impact of OSA on sex-specific outcomes after acute myocardial infarction (AMI). Methods and Results The VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients) study enrolled 3572 adults aged 18 to 55 years with AMI from the United States and Spain during 2008 to 2012. We included patients for whom the Berlin Questionnaire for OSA was scored at the time of AMI admission (3141; 2105 women, 1036 men). We examined the sex-specific association between baseline OSA risk with functional outcomes including health status and depressive symptoms at 1 and 12 months after AMI. Among both groups, 49% of patients were at high risk for OSA (1040 women; 509 men), but only 4.7% (148) of patients had a diagnosed history of OSA. Though patients with a high OSA risk reported worse physical and mental health status and depression than low-risk patients in both sexes, the difference in these functional outcomes was wider in women than men. Moreover, women with a high OSA risk had worse health status, depression, and quality of life than high-risk men, both at baseline and at 1 and 12 months after AMI. Conclusions Young women with a high OSA risk have poorer health status and more depressive symptoms than men at the time of AMI, which may place them at higher risk of poorer health outcomes over the year following the AMI. Further, the majority of patients at high risk of OSA are undiagnosed at the time of presentation of AMI.

Sex differences in patterns of referral and resource utilization in the cardiology clinic: an outpatient analysis

Aims

Women may have different management patterns than men in specialised care. Our aim was to assess potential sex differences in referral, management and outcomes of patients attending outpatient cardiac consultations.

Methods and results

Retrospective observational analysis of patients ≥18 years referred for the first time from primary care to a tertiary hospital cardiology clinic in 2017-2018, comparing reasons for referral, decisions and post-visit outcomes by sex.A total of 5,974 patients, 2,452 (41.0%) men aged 59.2 ± 18.6 years and 3,522 (59.0%) women aged 64.5 ± 17.9 years (P < 0.001) were referred for a first cardiology consultation. The age-related referral rates were higher in women. The most common reasons for consultation were palpitations in women (n = 676; 19.2%) and ECG abnormalities in men (n = 570; 23.2%). Delays to cardiology visits and additional tests were similar. During 24 months of follow-up, women had fewer cardiology hospitalisations (204; 5.8% vs. 229; 9.3%; P = 0.003) and lower mortality (65; 1.8% vs. 66; 2.7%; P = 0.028), but those aged <65 years had more emergency department visits (756; 48.5% vs. 560; 39.9%, P < 0.001) than men.

Conclusion

There are substantial sex differences in primary care cardiology referral patterns, including causes, rates, decisions and outcomes, which are only partially explained by age differences. Further research is needed to understand the reasons for these differences.

Subclinical atherosclerosis and accelerated epigenetic age mediated by inflammation: a multi-omics study

AIMS

Epigenetic age is emerging as a personalized and accurate predictor of biological age. The aim of this article is to assess the association of subclinical atherosclerosis with accelerated epigenetic age and to investigate the underlying mechanisms mediating this association.

METHODS AND RESULTS

Whole blood methylomics, transcriptomics, and plasma proteomics were obtained for 391 participants of the Progression of Early Subclinical Atherosclerosis study. Epigenetic age was calculated from methylomics data for each participant. Its divergence from chronological age is termed epigenetic age acceleration. Subclinical atherosclerosis burden was estimated by multi-territory 2D/3D vascular ultrasound and by coronary artery calcification. In healthy individuals, the presence, extension, and progression of subclinical atherosclerosis were associated with a significant acceleration of the Grim epigenetic age, a predictor of health and lifespan, regardless of traditional cardiovascular risk factors. Individuals with an accelerated Grim epigenetic age were characterized by an increased systemic inflammation and associated with a score of low-grade, chronic inflammation. Mediation analysis using transcriptomics and proteomics data revealed key pro-inflammatory pathways (IL6, Inflammasome, and IL10) and genes (IL1B, OSM, TLR5, and CD14) mediating the association between subclinical atherosclerosis and epigenetic age acceleration.

CONCLUSION

The presence, extension, and progression of subclinical atherosclerosis in middle-aged asymptomatic individuals are associated with an acceleration in the Grim epigenetic age. Mediation analysis using transcriptomics and proteomics data suggests a key role of systemic inflammation in this association, reinforcing the relevance of interventions on inflammation to prevent cardiovascular disease.

Effect of Routine Invasive vs Conservative Strategy in Older Adults With Frailty and Non-ST-Segment Elevation Acute Myocardial Infarction: A Randomized Clinical Trial

Importance

To our knowledge, no randomized clinical trial has compared the invasive and conservative strategies in frail, older patients with non-ST-segment elevation acute myocardial infarction (NSTEMI).

Objective

To compare outcomes of invasive and conservative strategies in frail, older patients with NSTEMI at 1 year.

Design, Setting, and Participants

This multicenter randomized clinical trial was conducted at 13 Spanish hospitals between July 7, 2017, and January 9, 2021, and included 167 older adult (≥70 years) patients with frailty (Clinical Frailty Scale score ≥4) and NSTEMI. Data analysis was performed from April 2022 to June 2022.

Interventions

Patients were randomized to routine invasive (coronary angiography and revascularization if feasible; n = 84) or conservative (medical treatment with coronary angiography for recurrent ischemia; n = 83) strategy.

Main Outcomes and Measures

The primary end point was the number of days alive and out of the hospital (DAOH) from discharge to 1 year. The coprimary end point was the composite of cardiac death, reinfarction, or postdischarge revascularization.

Results

The study was prematurely stopped due to the COVID-19 pandemic when 95% of the calculated sample size had been enrolled. Among the 167 patients included, the mean (SD) age was 86 (5) years, and mean (SD) Clinical Frailty Scale score was 5 (1). While not statistically different, DAOH were about 1 month (28 days; 95% CI, -7 to 62) greater for patients managed conservatively (312 days; 95% CI, 289 to 335) vs patients managed invasively (284 days; 95% CI, 255 to 311; P = .12). A sensitivity analysis stratified by sex did not show differences. In addition, we found no differences in all-cause mortality (hazard ratio, 1.45; 95% CI, 0.74-2.85; P = .28). There was a 28-day shorter survival in the invasive vs conservatively managed group (95% CI, -63 to 7 days; restricted mean survival time analysis). Noncardiac reasons accounted for 56% of the readmissions. There were no differences in the number of readmissions or days spent in the hospital after discharge between groups. Neither were there differences in the coprimary end point of ischemic cardiac events (subdistribution hazard ratio, 0.92; 95% CI, 0.54-1.57; P = .78).

Conclusions and Relevance

In this randomized clinical trial of NSTEMI in frail older patients, there was no benefit to a routine invasive strategy in DAOH during the first year. Based on these findings, a policy of medical management and watchful observation is recommended for older patients with frailty and NSTEMI.

Sex differences in temporal trends in main and secondary pulmonary embolism diagnosis and case fatality rates: 2003-2019

AIMS

There is controversy regarding the incidence and outcomes of pulmonary embolism (PE) according to sex. Our aim was to address sex differences in temporal trends in main and secondary hospital PE diagnoses, management and case fatality rates (CFR).

METHODS AND RESULTS

Retrospective analysis of Spain´s National Healthcare System hospital database, years 2003-2019, for patients ≥18 years with main or secondary PE diagnosis. Trends by sex in hospital diagnosis, use of procedures, and CFRs were analysed by joinpoint and Poisson regression models. Of 339 469 PE diagnoses, 52% were in women. Sixty-five percent were main diagnosis, 35.2% secondary. Total annual diagnoses and frequentation rates increased similarly in men and women: average annual percent change (AAPC): 2.0% (95% CI, 1.3-2.6; P < 0.005). Secondary PEs were more common in men (37.8% vs. 32.9%, P < 0.001). Men showed greater comorbidity than women (Charlson index 2.22 ± 0.01 vs. 1.74 ± 0.01, P < 0.001), particularly cancer in the secondary diagnosis group (40.9% vs. 31.6%, P < 0.001). CFRs for PE as main diagnosis were comparable and decreased in parallel in men (from 13.8% in 2003 to 7.3% in 2019) and women (from 13.1% in 2003 to 6.9% in 2019). However, for PE as secondary diagnosis, CFRs remained higher (P < 0.001) in men (from 42.5% in 2003 to 26.2% in 2019) than women (from 34.4% in 2003 to 22.8% in 2019).

CONCLUSION

PE hospital diagnosis increased significantly between 2003 and 2019 in men and women for both main and secondary diagnosis. Although in-hospital CFR decreased one third still remains very high, especially in men with secondary PE diagnosis.

Static first-minute-frame (FMF) PET imaging after 18F-labeled amyloid tracer injection is correlated to [18F]FDG PET in patients with primary progressive aphasia

OBJECTIVE

To study the correlation between a static PET image of the first-minute-frame (FMF) acquired with ¹⁸F-labeled amyloid-binding radiotracers and brain [¹⁸F]FDG PET in patients with primary progressive aphasia (PPA).

MATERIAL AND METHODS

The study cohort includes 17 patients diagnosed with PPA with the following distribution: 9 nonfluent variant PPA, 4 logopenic variant PPA, 1 semantic variant PPA, 3 unclassifiable PPA. Regional SUVRs are extracted from FMFs and their corresponding [¹⁸F]FDG PET images and Pearson's correlation coefficients are calculated.

RESULTS

SUVRs of both images show similar patterns of regional cerebral alterations. Intrapatient correlation analyses result in a mean coefficient of r=0.94±0.06. Regional interpatient correlation coefficients of the study cohort are greater than 0.81. Radiotracer-specific and variant-specific subcohorts show no difference in the similarity between the images.

CONCLUSIONS

The static FMF could be a valid alternative to dynamic early-phase amyloid PET proposed in the literature, and a neurodegeneration biomarker for the diagnosis and classification of PPA in amyloid PET studies.

External applicability of the Effect of ticagrelor on Health Outcomes in diabEtes Mellitus patients Intervention Study (THEMIS) trial: An analysis of patients with diabetes and coronary artery disease in the REduction of Atherothrombosis for Continued Health (REACH) registry

AIMS

THEMIS is a double-blind, randomized trial of 19,220 patients with diabetes mellitus and stable coronary artery disease (CAD) comparing ticagrelor to placebo, in addition to aspirin. The present study aimed to describe the proportion of patients eligible and reasons for ineligibility for THEMIS within a population of patients with diabetes and CAD included in the Reduction of Atherothrombosis for Continued Health (REACH) registry.

METHODS AND RESULTS

The THEMIS eligibility criteria were applied to REACH patients. THEMIS included patients ≥50 years with type 2 diabetes and stable CAD as determined by either a history of previous percutaneous coronary intervention, coronary artery bypass grafting, or documentation of angiographic stenosis of ≥50% of at least one coronary artery. Patients with prior myocardial infarction or stroke were excluded. In REACH, 10,156 patients had stable CAD and diabetes. Of these, 6515 (64.1%) patients had at least one exclusion criteria. From the remaining population, 784 patients did not meet inclusion criteria (7.7%) mainly due to absence of aspirin treatment (7.2%), yielding a 'THEMIS-eligible population' of 2857 patients (28.1% of patients with diabetes and stable CAD). The main reasons for exclusion were a history of myocardial infarction (53.1%), use of oral anticoagulation (14.5%), or history of stroke (12.9%). Among the 4208 patients with diabetes and a previous PCI, 1196 patients (28.4%) were eligible for inclusion in the THEMIS-PCI substudy.

CONCLUSIONS

In a population of patients with diabetes and stable coronary artery disease, a sizeable proportion appear to be 'THEMIS eligible.'

Long-term outcomes of extended DAPT in a real-life cohort of consecutive STEMI patients

INTRODUCTION AND OBJECTIVES

Dual antiplatelet therapy (DAPT) duration after ST-segment elevation myocardial infarction (STEMI) remains a matter of debate.

METHODS

We analyzed the effect of DAPT on 5-year all-cause mortality, cardiovascular mortality, and cardiovascular readmission or mortality in a cohort of 1-year survivor STEMI patients.

RESULTS

A total of 3107 patients with the diagnosis of STEMI were included: 93% of them were discharged on DAPT, a therapy that persisted in 275 high-risk patients at 5 years. Cardiovascular mortality in patients on single antiplatelet therapy vs DAPT at 5 years was 1.4% vs 3.6% (P <.01), respectively, whereas noncardiovascular mortality was 3.3% vs 5.8% (P=.049) at 5 years. Cardiovascular readmission or mortality in patients with single antiplatelet therapy vs DAPT was 11.4% vs 46.5% (P <.001). Extended DAPT was independently associated with worse 5-year all-cause mortality (HR, 2.16; 95%CI, 1.40-3.33), cardiovascular mortality (HR, 2.83; 95%CI, 1.37-5.84), and cardiovascular readmission or mortality (HR, 5.20; 95%CI, 3.96-6.82). These findings were confirmed in propensity score matching and inverse probability weighting analyses.

CONCLUSIONS

Our results suggest the hypothesis that, in 1-year STEMI survivors, extending DAPT up to 5 years in high-risk patients does not improve their long-term prognosis.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Trends in cardiovascular care in the National Health System in Spain. Data from the RECALCAR project 2011-2020

INTRODUCTION AND OBJECTIVES

The RECALCAR project (Resources and Quality in Cardiology), an initiative of the Spanish Society of Cardiology, aims to standardize information to generate evidence on cardiovascular health outcomes. The objective of this study was to analyze trends in the resources and activity of cardiology units and/or services and to identify the results of cardiovascular care during the last decade in Spain.

METHODS

The study was based on the 2 annual data sources of the RECALCAR project: a survey on resources and activity of cardiology units and/or services (2011-2020) and the minimum data set of the National Health System (2011-2019), referring to heart failure (HF), STEMI, and non-STEMI.

RESULTS

The survey included 70% of cardiology units and/or services in Spain. The number of hospital beds and length of stay decreased, while there was a notable increase in the number of cardiac imaging studies and percutaneous therapeutic procedures performed. Age- and sex-adjusted admissions for HF tended to decrease, despite an increase in mortality and the percentage of readmissions. In contrast, the trend in mortality and readmissions was highly favorable in STEMI; in non-STEMI, although positive, the trend was less marked.

CONCLUSIONS

The information provided by the RECALCAR project shows a favorable trend in the last decade in resources, activity and results of certain cardiovascular processes and constitutes an essential source for future improvements and decision-making in health policy.

Time trends in the epidemiology of nonrheumatic aortic valve disease in Spain, 2003-2018

INTRODUCTION AND OBJECTIVES

The impact of therapeutic improvements in nonrheumatic aortic valve disease (NRAVD) has been assessed at the patient level but not in the whole population with the disease. Our objective was to assess temporal trends in hospitalization rates, treatment and fatality rates in patients with a main or secondary NRAVD diagnosis.

METHODS

Retrospective analysis of administrative claims from patients hospitalized with a main or secondary NRAVD diagnosis between 2003 and 2018 in Spain. Time trends in age- and sex-standardized hospitalization and procedure rates, baseline characteristics and case fatality rates by diagnosis type were assessed by Poisson regression and joinpoint analysis.

RESULTS

Hospital admissions in patients with NRAVD increased from 69 213 in 2003 to 136 185 in 2018. The crude in-hospital fatality rate increased from 6.7% to 8.7% (IRR, 1.015; 95%CI, 1.012-1.018; P <.001) without changes after adjustment. Adjusted fatality rates decreased in patients with a main NRAVD diagnosis (5.5% to 3.5%; IRR, 0.953; 95%CI, 0.942-0.964) but increased in those with a secondary diagnosis (8.0% to 8.8%; IRR, 1.005; 95%CI, 1.002-1.009). Aortic valve replacements increased from 10.5 to 17.1 procedures per 100 000 population (IRR, 1.033; 95%CI, 1.030-1.037), mainly driven by transcatheter procedures (IRR, 1.345; 95%CI, 1.302-1.389).

CONCLUSIONS

Hospitalizations in patients with NRAVD are increasing, with most being secondary diagnoses. The use of aortic valve replacement is increasing with a reduction in fatality rates but only in patients with a main diagnosis.

The time is now: Achieving FH paediatric screening across Europe - The Prague Declaration

Familial hypercholesterolaemia (FH) is the most common inherited metabolic disorder characterized by high cholesterol and if left untreated leads to premature cardiovascular disease, such as heart attacks. Treatment that begins early in life, particularly in childhood, is highly efficacious in preventing cardiovascular disease and cost-effective, thus early detection of FH is crucial. However, in Europe, less than 10% of people living with FH are diagnosed and even less receive life-saving treatment. The Prague Declaration is a call to action for national and European Union policymakers and decision-makers and a result of the Czech EU Presidency meeting on FH Paediatric Screening (early detection of inherited high cholesterol) at the Czech Senate in Prague on 6th September 2022. It builds on a considerable body of evidence which was discussed at the Technical Meeting under the auspices of the Slovenian EU Presidency in October 2021. The Prague meeting addressed the outstanding barriers to the systematic implementation of FH paediatric screening across Europe. In this article, we present the key points from the Prague meeting and concrete actions needed to move forward.

CD69 expression on regulatory T cells protects from immune damage after myocardial infarction

Increasing evidence has pointed to the important function of T cells in controlling immune homeostasis and pathogenesis after myocardial infarction (MI), although the underlying molecular mechanisms remain elusive. In this study, a broad analysis of immune markers in 283 patients revealed significant CD69 overexpression on Tregs after MI. Our results in mice showed that CD69 expression on Tregs increased survival after left anterior descending (LAD) coronary artery ligation. Cd69^–/– mice developed strong IL-17⁺ γδT cell responses after ischemia that increased myocardial inflammation and, consequently, worsened cardiac function. CD69⁺ Tregs, by induction of AhR-dependent CD39 ectonucleotidase activity, induced apoptosis and decreased IL-17A production in γδT cells. Adoptive transfer of CD69⁺ Tregs into Cd69^–/– mice after LAD ligation reduced IL-17⁺ γδT cell recruitment, thus increasing survival. Consistently, clinical data from 2 independent cohorts of patients indicated that increased CD69 expression in peripheral blood cells after acute MI was associated with a lower risk of rehospitalization for heart failure (HF) after 2.5 years of follow-up. This result remained significant after adjustment for age, sex, and traditional cardiac damage biomarkers. Our data highlight CD69 expression on Tregs as a potential prognostic factor and a therapeutic option to prevent HF after MI.

Interaction between va-ecmo and the right ventricle

BACKGROUND

The response of the right ventricle (RV) to the hemodynamic effects of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is currently unpredictable. We hypothesized that the presence of uni- or bi-ventricular failure before implantation and the cannulation strategy may influence this interaction. We sought to assess the RV performance during VA-ECMO support and identify RV-related predictors of successful weaning.

METHODS

Changes of RV size and function during VA-ECMO support by echocardiography were retrospectively analyzed in 87 consecutive adult patients between February, 2008, and June, 2017. Predictors of successful weaning due to myocardial recovery were evaluated by multivariable logistic regression.

RESULTS

RV echocardiographic parameters did not vary significantly during VA-ECMO support, neither after stratification by type of cannulation or the presence of isolated or biventricular failure. Successful weaning was conditioned by the absence of RV dysfunction before implantation (OR, 14.7; 95%CI, 13.3-140.3; p=0.025) or in the last day of support (OR, 9.5; 95%CI, 1.6-54; p=0.011), and was favored by a total or partial recovery of RV function during the assistance (OR, 6.2; 95%CI, 1.7-22.4; p=0.005). RV improvement was more often observed in patients with acute RV failure and longer support, while VA-ECMO configuration, additional mechanical support or pharmacological therapy had no effect.

CONCLUSIONS

Preservation or improvement of RV function during VA-ECMO is essential for successful weaning. RV echocardiographic performance does not change significantly during VA-ECMO support and is not influenced by cannulation type or the presence of uni- or bi-ventricular failure before implantation.

Positive psychology differences and risk stratification between STEMI and NSTEMI

Funding Acknowledgements

Type of funding sources: Foundation. Main funding source(s): Spanish Society of Cardiology

Introduction

Clinical presentation of myocardial infarction (MI) is broad and can be differentiated into different risk groups based on electrocardiogram (ECG) presentation, ST-segment elevation MI (STEMI) or Non-ST-segment elevation MI (NSTEMI), with different in-hospital mortality rates and short-term mortality rates after discharge. Psychological variables also have an impact on post-MI prognosis. Factors such as stress, anxiety or depression have been associated with a higher cardiovascular risk and positive psychological variables, such as optimism, have has been related to a lower risk of cardiovascular mortality after MI. Patients may present different psychological profiles regarding the early ECG presentation which could be associated with differences in cardiovascular events and mortality.

Purpose

The aim of this study is to assess whether positive and negative psychological factors are associated with early ECG presentation. This is relevant as it could help refining risk stratification and improving secondary prevention, including psychological interventions.

Methods

93 patients admitted to a tertiary hospital with MI were divided into groups based on the early electrocardiogram presentation (STEMI vs. NSTEMI). Differences in sociodemographic, clinical history, lifestyle, coping styles, mental and physical quality of life, anxiety, depression, stress, optimism, positive and negative affect and psychological well-being were assessed using Chi-Square test and Student-t test. Psychological well-being was composed by the following dimensions: self-acceptance, positive relationships, autonomy, environmental domain, personal growth and purpose in life. If any difference emerged in the sociodemographic control variables (age and sex), the corresponding analyses of covariance (ANCOVAs) were performed.

Results

STEMI patients (n = 64) had a significantly lower mean age (p = 0.02), lower BMI (p = 0.03) and presented less previous heart failure (p = 0.03). Significantly lower levels of optimism (p = 0.03) compared to the NSTEMI group (n = 29) were observed, difference that showed a medium effect size magnitude (d = 0.48). ECG presentation explain 8% variance of levels of optimism and age explain 6% of the variability of dispositional optimism. STEMI patients also perceived a significant higher level of mental quality of life comparing to NSTEMI group (p = 0.05), difference that had a medium magnitude (d = 0.43). ECG presentation contribute in 5% to the variability of mental quality of life, but the age had no significant effect (p = 0.37). No differences were observed between groups in coping styles, anxiety, depression, stress, positive and negative affect and psychological well-being.

Conclusions

STEMI patients seem to have different psychological profile compared with NSTEMI. Particularly for optimism and mental quality of life. This may have future implications for psychological rehabilitation of patients with MI.

The Clinical outcomes, healthcare resource utilization, and related costs (COHERENT) model. Application in heart failure patients

INTRODUCTION AND OBJECTIVES

Composite endpoints are widely used but have several limitations. The Clinical outcomes, healthcare resource utilization and related costs (COHERENT) model is a new approach for visually displaying and comparing composite endpoints including all their components (incidence, timing, duration) and related costs. We aimed to assess the validity of the COHERENT model in a patient cohort.

METHODS

A color graphic system displaying the percentage of patients in each clinical situation (vital status and location: at home, emergency department [ED] or hospital) and related costs at each time point during follow-up was created based on a list of mutually exclusive clinical situations coded in a hierarchical fashion. The system was tested in a cohort of 1126 patients with acute heart failure from 25 hospitals. The system calculated and displayed the time spent in each clinical situation and health care resource utilization-related costs over 30 days.

RESULTS

The model illustrated the times spent over 30 days (2.12% in ED, 23.6% in index hospitalization, 2.7% in readmissions, 65.5% alive at home, and 6.02% dead), showing significant differences between patient groups, hospitals, and health care systems. The tool calculated and displayed the daily and cumulative health care-related costs over time (total, €4 895 070; mean, €144.91 per patient/d).

CONCLUSIONS

The COHERENT model is a new, easy-to-interpret, visual display of composite endpoints, enabling comparisons between patient groups and cohorts, including related costs. The model may constitute a useful new approach for clinical trials or observational studies, and a tool for benchmarking, and value-based health care implementation.

ESC guidance for the diagnosis and management of cardiovascular disease during the COVID-19 pandemic: part 2-care pathways, treatment, and follow-up

AIMS

Since its emergence in early 2020, the novel severe acute respiratory syndrome coronavirus 2 causing coronavirus disease 2019 (COVID-19) has reached pandemic levels, and there have been repeated outbreaks across the globe. The aim of this two part series is to provide practical knowledge and guidance to aid clinicians in the diagnosis and management of cardiovascular (CV) disease in association with COVID-19.

METHODS AND RESULTS

A narrative literature review of the available evidence has been performed, and the resulting information has been organized into two parts. The first, which was reported previously, focused on the epidemiology, pathophysiology, and diagnosis of CV conditions that may be manifest in patients with COVID-19. This second part addresses the topics of: care pathways and triage systems and management and treatment pathways, both of the most commonly encountered CV conditions and of COVID-19; and information that may be considered useful to help patients with CV disease (CVD) to avoid exposure to COVID-19.

CONCLUSION

This comprehensive review is not a formal guideline but rather a document that provides a summary of current knowledge and guidance to practicing clinicians managing patients with CVD and COVID-19. The recommendations are mainly the result of observations and personal experience from healthcare providers. Therefore, the information provided here may be subject to change with increasing knowledge, evidence from prospective studies, and changes in the pandemic. Likewise, the guidance provided in the document should not interfere with recommendations provided by local and national healthcare authorities.

Depression and Perceived Stress After Spontaneous Coronary Artery Dissection and Comparison With Other Acute Myocardial Infarction (the VIRGO Experience)

Data on depression and stress among patients with spontaneous coronary artery dissection (SCAD) are limited. Using data from the VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients) study, which prospectively enrolled 3,572 acute myocardial infarction (AMI) patients between 18 and 55 years of age, we identified 67 SCAD cases. We compared Patient Health Questionnaire-9 (PHQ-9) and 14-item Perceived Stress Scale (PSS-14) scores obtained at baseline, 1 month, and 12 months between SCAD and AMI of all other causes. Using longitudinal linear mixed-effects analysis, we compared depression and stress scores between SCAD and other AMI, adjusting for time and selected covariates. Patients with SCAD had lower baseline PHQ-9 scores (6.1 ± 6.0 vs 7.7 ± 6.4 for other patients with AMI, p = 0.03), similar 1-month scores, and lower 12-month scores (3.2 ± 4.3 vs 4.9 ± 5.5, p = 0.004). At baseline and 1 month, patients with SCAD had similar PSS-14 scores to those of other patients with AMI. At 12 months, patients with SCAD had lower scores (18.4 ± 8.8 vs 21.5 ± 9.3 for other patients with AMI, p = 0.009). After adjustment for cardiovascular risk factors, co-morbidities, and clinical acuity, no differences in PHQ-9 or PSS-14 scores remained between SCAD and other AMI. Similar results were obtained in a subgroup analysis of only women with SCAD and other AMI. In conclusion, patients with SCAD had a relatively lower burden of depression and perceived stress than other patients with AMI, potentially because of fewer co-morbidities and favorable socioeconomic factors. However, given high depression and stress burden in both SCAD and other patients with AMI, routine screening can help identify and treat these patients.

Sex differences in mortality after an acute coronary syndrome increase with lower country wealth and higher income inequality

INTRODUCTION AND OBJECTIVES

Although several factors associated with sex differences in the management and outcomes after acute coronary syndrome (ACS) have been reported, little is known about the influence of socioeconomic factors on sex disparities. Our aim was to evaluate the influence of country wealth and income inequality on national sex differences in mortality after ACS.

METHODS

Sex differences in 2-year postdischarge mortality were evaluated in 23 489 ACS patients from the EPICOR and EPICOR Asia registries. Adjusted Cox regression models by country-based terciles of gross national income per capita and income inequality were used.

RESULTS

Women (24.3%) were older than men (65.5 vs 59.4 years, P <.001), had more comorbidities, were less often revascularized (63.6% vs 75.6%, P <.001) and received fewer guideline recommended therapies at discharge. Compared with men, a higher percentage of women died during follow-up (6.4% vs 4.9%, P <.001). The association between sex and mortality changed direction from hazard ratio (HR) 1.32 (95%CI, 1.17-1.49) in the univariate assessment to HR 0.76 (95%CI, 0.67-0.87) after adjustment for confounders. These differences were more evident with increasing country wealth (HR_{low-incomecountries} = 0.85; 95%CI, 0.72-1.00; HR_{mid-incomecountries} = 0.66; 95%CI, 0.50-0.87; HR_{high-incomecountries} = 0.60; 95%CI, 0.40-0.90; trend test P = .115) and with decreasing income inequality (HR_{low-inequalityindex} = 0.54; 95%CI, 0.36-0.81; HR_{intermediate-inequalityindex} = 0.66; 95%CI, 0.50-0.88; HR_{high-inequalityindex} = 0.87; 95%CI, 0.74-1.03; trend test P = .031).

CONCLUSIONS

Women with ACS living in high socioeconomic countries showed a lower postdischarge mortality risk compared with men. This risk was attenuated in countries with poorer socioeconomic background, where adjusted mortality rates were similar between women and men.

Cost-effectiveness of ticagrelor in patients with type 2 diabetes and coronary artery disease: a European economic evaluation of the THEMIS trial

AIMS

To conduct a health economic evaluation of ticagrelor in patients with type 2 diabetes and coronary artery disease (CAD) from a multinational payer perspective. Cost-effectiveness and cost-utility of ticagrelor were evaluated in the overall effect of Ticagrelor on Health Outcomes in Diabetes Mellitus Patients Intervention Study (THEMIS) trial population and in the predefined patient group with prior percutaneous coronary intervention.

METHODS AND RESULTS

A Markov model was developed to extrapolate patient outcomes over a lifetime horizon. The primary outcome was incremental cost-effectiveness ratios (ICERs), which were compared with conventional willingness-to-pay thresholds [€47 000/quality-adjusted life-year (QALY) in Sweden and €30 000/QALY in other countries].Treatment with ticagrelor resulted in QALY gains of up to 0.045 in the overall population and 0.099 in patients with percutaneous coronary intervention (PCI). Increased costs and benefits translated to ICERs ranged between €27 894 and €42 252/QALY across Sweden, Germany, Italy, and Spain in the overall population. In patients with prior PCI, estimated ICERs improved to €18 449, €20 632, €20 233, and €13 228/QALY in Sweden, Germany, Italy, and Spain, respectively, driven by higher event rates and treatment benefit.

CONCLUSION

Based on THEMIS results, ticagrelor plus aspirin compared with aspirin alone may be cost-effective in some European countries in patients with T2DM and CAD and no prior myocardial infarction (MI) or stroke. Additionally, ticagrelor is likely to be cost-effective across European countries in patients with a history of PCI.

Early vs. Delayed Initiation of Treatment With P2Y12 Inhibitors in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials

Aims

Whether early or delayed dual antiplatelet therapy initiation is better in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) is unclear. We assessed the evidence for comparing the efficacy and safety of early vs. delayed P2Y12 inhibitor initiation in NSTE-ACS.

Methods

The randomized controlled trials with available comparisons between early and delayed initiation of P2Y12 inhibitors (clopidogrel, prasugrel, and ticagrelor) in patients with NSTE-ACS until January 2021 were reviewed. The primary outcomes were trial-defined major adverse cardiovascular events (MACEs) and bleeding. Secondary outcomes were all-cause mortality, cardiovascular mortality, myocardial infarction, stent thrombosis, urgent coronary revascularization, and stroke. Frequentist random-effects network meta-analyses were conducted, ranking best treatments per outcome with p-scores.

Results

A total of nine trials with intervention arms including early and delayed initiation of clopidogrel (n = 5), prasugrel (n = 8), or ticagrelor (n = 6) involving 40,096 patients were included. Early prasugrel (hazard ratio [HR], 0.59; 95% confidence interval [95%CI], 0.40–0.87), delayed prasugrel (HR, 0.60; 95%CI 0.43–0.84), and early ticagrelor (HR, 0.84; 95%CI, 0.74–0.96) significantly reduced MACE compared with early clopidogrel, but increased bleeding risk. Delayed prasugrel ranked as the best treatment to reduce MACE (p-score=0.80), early prasugrel to reduce all-cause mortality, cardiovascular mortality, stent thrombosis, and stroke, and delayed clopidogrel to reduce bleeding (p-score = 0.84). The risk of bias was low for all trials.

Conclusion

In patients with NSTE-ACS, delayed prasugrel initiation was the most effective strategy to reduce MACE. Although early prasugrel was the best option to reduce most secondary cardiovascular outcomes, it was associated with the highest bleeding risk. The opposite was found for delayed clopidogrel.

Health status outcomes after spontaneous coronary artery dissection and comparison with other acute myocardial infarction: The VIRGO experience

Background

Data on health status outcomes after spontaneous coronary artery dissection (SCAD) are limited.

Methods and findings

Using the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study we compared patients with SCAD and other acute myocardial infarction (AMI) at presentation (baseline), 1-month, and-12 months using standardized health status instruments. Among 3572 AMI patients ≤ 55 years, 67 had SCAD. SCAD patients were younger (median age (IQR) 45 (40.5–51) years vs. 48 (44–52) in other AMI, p = 0.003), more often female (92.5% vs. 66.6%), have college education (73.1% vs. 51.7%) and household income >$100,000 (43.3% vs. 17.7% (All p<0.001). SCAD patients at baseline had higher mean ± SD Short Form-12 [SF-12] physical component scores [PCS] (48.7±10.2 vs. 43.8±12.1, p<0.001) and mental component scores [MCS] (49.6±12.4 vs. 45.4±12.5, p = 0.008), and at 12-months [PCS (50.1±9.0 vs. 44.3±12.3, p<0.001) and MCS (53±10.1 vs 50.2±11.0, p = 0.045)]. The Euro-Quality of Life Scale [EQ-5D] VAS and EQ-5D index scores were similar at baseline, but higher at 12-months for SCAD (EQ-5D VAS: 82.2±10.2 vs. 72.3±21.0, p<0.001; EQ-5D index scores; 90.2±15.3 vs. 83.7±19.8, p = 0.012). SCAD patients had better baseline Seattle Angina Questionnaire [SAQ] physical limitation (88.8±20.1 vs. 81.2±25.4, p = 0.017). At 12-months SCAD patients had better physical limitation (98.0±8.5 vs. 91.4±18.8, p = 0.007), angina frequency (96.4±8.8 vs. 91.3±16.8, p = 0.018) and quality of life scores (80.7±14.7 vs 72.2±23.2, p = 0.005). Magnitude of change in health status from baseline to 12-months was not statistically different between the groups. After adjustment for time and comorbidities there remained no difference in most health status outcomes.

Conclusions

SCAD patients fare marginally better than other AMI patients on most health status instruments and have similar 12-month health status recovery. Better pre-event health status suggests a need to modify exercise prescriptions and cardiac rehabilitation protocols to better assist this physically active population to recover.

Primary vs. Secondary Heart Failure Diagnosis: Differences in Clinical Outcomes, Healthcare Resource Utilization and Cost

Background

There is scarce information on patients with secondary heart failure diagnosis (sHF). We aimed to compare the characteristics, burden, and outcomes of sHF with those with primary HF diagnosis (pHF).

Methods

Retrospective, observational study on patients ≥18 years with emergency department (ED) visits during 2018 with pHF and sHF in ED or hospital (ICD-10-CM) diagnostic codes. Baseline characteristics, 30-day and 1-year mortality, readmission and re-ED visit rates, and costs were compared between sHF and pHF.

Results

Out of the 797 patients discharged home from the ED, 45.5% had sHF, and these presented lower 1-year hospitalization, re-ED visit rates, and costs. In contrast, out of the 2,286 hospitalized patients, 55% had sHF and 45% pHF. Hospitalized sHF patients had significantly (p < 0.01) greater comorbidity, lower use of recommended HF therapies, longer length of stay (10.8 ± 10.1 vs. 9.7 ± 7.9 days), and higher in-hospital and 1-year mortality (32 vs. 25.8%) with no significant differences in readmission rates and lower 1-year re-ED visit rate. Hospitalized sHF patients had higher total costs (€12,262,422 vs. €9,144,952, p < 0.001), mean cost per patient-year (€9,755 ± 13,395 vs. €8,887 ± 12,059), and average daily cost per patient.

Conclusion

Hospitalized sHF patients have a worse initial prognosis, greater use of healthcare resources, and higher costs.

Since its emergence in early 2020, the novel severe acute respiratory syndrome coronavirus 2 causing coronavirus disease 2019 (COVID-19) has reached pandemic levels, and there have been repeated outbreaks across the globe. The aim of this two part series is to provide practical knowledge and guidance to aid clinicians in the diagnosis and management of cardiovascular (CV) disease in association with COVID-19.

METHODS AND RESULTS

A narrative literature review of the available evidence has been performed, and the resulting information has been organized into two parts. The first, which was reported previously, focused on the epidemiology, pathophysiology, and diagnosis of CV conditions that may be manifest in patients with COVID-19. This second part addresses the topics of: care pathways and triage systems and management and treatment pathways, both of the most commonly encountered CV conditions and of COVID-19; and information that may be considered useful to help patients with CV disease (CVD) to avoid exposure to COVID-19.

CONCLUSION

This comprehensive review is not a formal guideline but rather a document that provides a summary of current knowledge and guidance to practicing clinicians managing patients with CVD and COVID-19. The recommendations are mainly the result of observations and personal experience from healthcare providers. Therefore, the information provided here may be subject to change with increasing knowledge, evidence from prospective studies, and changes in the pandemic. Likewise, the guidance provided in the document should not interfere with recommendations provided by local and national healthcare authorities.
