Apolipoprotein A1 Infusions and Cardiovascular Outcomes after Acute Myocardial Infarction.

BACKGROUND: Cardiovascular events frequently recur after acute myocardial infarction, and low cholesterol efflux - a process mediated by apolipoprotein A1, which is the main protein in high-density lipoprotein - has been associated with an increased risk of cardiovascular events. CSL112 is human apolipoprotein A1 derived from plasma that increases cholesterol efflux capacity. Whether infusions of CSL112 can reduce the risk of recurrent cardiovascular events after acute myocardial infarction is unclear. METHODS: We conducted an international, double-blind, placebo-controlled trial involving patients with acute myocardial infarction, multivessel coronary artery disease, and additional cardiovascular risk factors. Patients were randomly assigned to receive either four weekly infusions of 6 g of CSL112 or matching placebo, with the first infusion administered within 5 days after the first medical contact for the acute myocardial infarction. The primary end point was a composite of myocardial infarction, stroke, or death from cardiovascular causes from randomization through 90 days of follow-up. RESULTS: A total of 18,219 patients were included in the trial (9112 in the CSL112 group and 9107 in the placebo group). There was no significant difference between the groups in the risk of a primary end-point event at 90 days of follow-up (439 patients [4.8%] in the CSL112 group vs. 472 patients [5.2%] in the placebo group; hazard ratio, 0.93; 95% confidence interval [CI], 0.81 to 1.05; P = 0.24), at 180 days of follow-up (622 patients [6.9%] vs. 683 patients [7.6%]; hazard ratio, 0.91; 95% CI, 0.81 to 1.01), or at 365 days of follow-up (885 patients [9.8%] vs. 944 patients [10.5%]; hazard ratio, 0.93; 95% CI, 0.85 to 1.02). The percentage of patients with adverse events was similar in the two groups; a higher number of hypersensitivity events was reported in the CSL112 group. CONCLUSIONS: Among patients with acute myocardial infarction, multivessel coronary artery disease, and additional cardiovascular risk factors, four weekly infusions of CSL112 did not result in a lower risk of myocardial infarction, stroke, or death from cardiovascular causes than placebo through 90 days.

Invasive vs. conservative management of older patients with non-ST-elevation acute coronary syndrome: individual patient data meta-analysis.

BACKGROUND AND AIMS: Older patients with non-ST-elevation acute coronary syndrome (NSTEACS) are less likely to receive guideline-recommended care including coronary angiography and revascularization. Evidence-based recommendations regarding interventional management strategies in this patient cohort are scarce. This meta-analysis aimed to assess the impact of routine invasive vs. conservative management of NSTEACS by using individual patient data (IPD) from all available randomized controlled trials (RCTs) including older patients. METHODS: MEDLINE, Web of Science and Scopus were searched between 1 January 2010 and 11 September 2023. RCTs investigating routine invasive and conservative strategies in persons >70 years old with NSTEACS were included. Observational studies or trials involving populations outside the target range were excluded. The primary endpoint was a composite of all-cause mortality and myocardial infarction (MI) at 1 year. One-stage IPD meta-analyses were adopted by use of random-effects and fixed-effect Cox models. This meta-analysis is registered with PROSPERO (CRD42023379819). RESULTS: Six eligible studies were identified including 1479 participants. The primary endpoint occurred in 181 of 736 (24.5%) participants in the invasive management group compared with 215 of 743 (28.9%) participants in the conservative management group with a hazard ratio (HR) from random-effects model of 0.87 (95% CI 0.63-1.22; P = .43). The hazard for MI at 1 year was significantly lower in the invasive group compared with the conservative group (HR from random-effects model 0.62, 95% CI 0.44-0.87; P = .006). Similar results were seen for urgent revascularization (HR from random-effects model 0.41, 95% CI 0.18-0.95; P = .037). There was no significant difference in mortality. CONCLUSIONS: No evidence was found that routine invasive treatment for NSTEACS in older patients reduces the risk of a composite of all-cause mortality and MI within 1 year compared with conservative management. However, there is convincing evidence that invasive treatment significantly lowers the risk of repeat MI or urgent revascularisation. Further evidence is needed from ongoing larger clinical trials.

Ticagrelor with or without aspirin following percutaneous coronary intervention in high-risk patients with concomitant peripheral artery disease: A subgroup analysis of the TWILIGHT randomized clinical trial.

BACKGROUND: The optimal antiplatelet regimen after percutaneous coronary intervention (PCI) in patients with peripheral artery disease (PAD) is still debated. This analysis aimed to compare the effect of ticagrelor monotherapy versus ticagrelor plus aspirin in patients with PAD undergoing PCI. METHODS: In the TWILIGHT trial, patients at high ischemic or bleeding risk that underwent PCI were randomized after 3 months of dual antiplatelet therapy (DAPT) to aspirin or matching placebo in addition to open-label ticagrelor for 12 additional months. In this post-hoc analysis, patient cohorts were examined according to the presence or absence of PAD. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), or stroke. Endpoints were assessed at 12 months after randomization. RESULTS: Among 7,119 patients, 489 (7%) had PAD and were older, more likely to have comorbidities, and multivessel disease. PAD patients had more bleeding or ischemic complications than no-PAD patients. Ticagrelor monotherapy compared to ticagrelor plus aspirin was associated with less BARC 2, 3, or 5 bleeding in PAD (4.6% vs 8.7%; HR 0.52; 95%CI 0.25-1.07) and no-PAD patients (4.0% vs 7.0%; HR 0.56; 95%CI 0.45-0.69; interaction P-value .830) and a similar risk of death, MI, or stroke in these 2 groups (interaction P-value .446). CONCLUSIONS: Despite their higher ischemic and bleeding risk, patients with PAD undergoing PCI derived a consistent benefit from ticagrelor monotherapy after 3 months of DAPT in terms of bleeding reduction without any relevant increase in ischemic events.

Effect of empagliflozin on total myocardial infarction events by type and additional coronary outcomes: insights from the randomized EMPA-REG OUTCOME trial.

BACKGROUND: The effect of empagliflozin, a sodium-glucose-co-transporter-2 inhibitor, on risk for myocardial infarction has not been fully characterized. METHODS: This study comprised prespecified and post-hoc analyses of the EMPA-REG OUTCOME trial in which 7020 people with type 2 diabetes (T2D) and cardiovascular disease [mostly atherosclerotic (ASCVD)] were randomized to empagliflozin or placebo and followed for a median 3.1 years. We assessed the effect of empagliflozin on total (first plus recurrent) events of centrally adjudicated fatal and non-fatal myocardial infarction (MI) using a negative binomial model with robust confidence intervals (CI) that preserves randomization and accounts for the within-patient correlation of multiple events. Post hoc, we analyzed types of MI: type 1 (related to plaque-rupture/thrombus), type 2 (myocardial supply-demand imbalance), type 3 (sudden-death related, i.e. fatal MI), type 4 (percutaneous coronary intervention-related), and type 5 (coronary artery bypass graft-related). MIs could be assigned to > 1 type. RESULTS: There were 421 total MIs (including recurrent); 299, 86, 26, 19, and 1 were classified as type 1, 2, 3, 4, and 5 events, respectively. Overall, empagliflozin reduced the risk of total MI events by 21% [rate ratio for empagliflozin vs. placebo, 0.79 (95% CI, 0.620-0.998), P = 0.0486], largely driven by its effect on type 1 [rate ratio, 0.79 (95% CI, 0.61-1.04)] and type 2 MIs [rate ratio, 0.67 (95% CI, 0.41-1.10)]. CONCLUSIONS: In T2D patients with ASCVD, empagliflozin reduced the risk of MIs, with consistent effects across the two most common etiologies, i.e. type 1 and 2. TRAIL REGISTRATION: URL: https://www.

Impact of empagliflozin on insulin needs in patients with heart failure and diabetes: An EMPEROR-Pooled analysis.

AIM: To assess the effect of empagliflozin on patients with comorbid heart failure (HF) and diabetes with or without baseline insulin, and to study the impact of empagliflozin on insulin requirements over time. MATERIALS AND METHODS: We performed a post-hoc analysis of pooled patient-level data from two cardiovascular outcomes trials of empagliflozin in HF (EMPEROR-Reduced and EMPEROR-Preserved trials). We undertook a subgroup analysis stratified by baseline insulin use, including all patients with diabetes. The studied endpoints included the primary composite endpoint of first hospitalization for HF or cardiovascular death, rate of decline of estimated glomerular filtration rate, composite renal outcome and rates of sustained insulin initiation. RESULTS: Among 4794 patients with diabetes, 1333 (658 in empagliflozin, 675 in placebo) were using insulin at baseline. The treatment effect of empagliflozin on the primary endpoint was consistent irrespective of insulin use [no insulin, hazard ratio 0.74, 95% confidence interval (CI) 0.63-0.86; using insulin, hazard ratio 0.81, 95% CI 0.66-1.00, pinteraction = .49], as was the effect on the rate of decline of the estimated glomerular filtration rate (pinteraction = .75). There was no effect of empagliflozin on the composite renal outcome in patients using or not using insulin (pinteraction = .30). Among patients not using insulin at baseline, those randomized to empagliflozin initiated insulin less frequently throughout the follow-up period compared with those receiving placebo (2.6% vs. 3.8%, odds ratio 0.66, 95% CI 0.50-0.88). CONCLUSIONS: Empagliflozin exerts a consistent benefit on cardiovascular outcomes and renal function decline, irrespective of baseline insulin use, and reduces the need for sustained insulin initiation in patients with HF and diabetes.

Quantifying the benefit-risk trade-off for individual patients in a clinical trial: principles and antithrombotic case study.

BACKGROUND: A treatment's overall favorable benefit-risk profile does not imply that every individual patient will benefit from the treatment. OBJECTIVES: To describe a statistical methodology for quantifying the benefit-risk trade-off in individual patients. METHODS: The method requires a large randomized controlled trial containing a primary efficacy outcome and a primary safety outcome, for instance, the Thrombin Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events-Thrombolysis in Myocardial Infarction 50 placebo-controlled trial of vorapaxar in 17 779 patients following myocardial infarction. Multivariate regression models predict each individual patient's risk of ischemic events (benefit) and major bleeding events (harm) based on their profile. Hence, each patient's predicted benefit from vorapaxar (reduction in ischemic events) and predicted risk (increase in bleeding events) were estimated. The relative importance of ischemic and bleeding events based on links to all-cause mortality was quantified, although the limitations of such weightings are noted. RESULTS: Overall results demonstrated both clear benefit and harm from vorapaxar. Substantial interindividual variation in both benefit and risk facilitated distinguishing patients with a favorable benefit-risk trade-off from those who did not. Such findings were applied to recommend vorapaxar in as many as 98.3% of patients in which a favorable mortality-weighted benefit-risk trade-off was present, in 77.2% of patients with ischemic benefit 20% greater than bleeding risk, or in as few as 45.5% of patients if an annual decrease in ischemic risk of ≥0.5% was also required. CONCLUSION: While overall randomized controlled trials of treatment benefit vs risk are valuable, models determining each individual patient's estimated absolute benefit and risk provide more useful insight regarding patient-specific benefit-risk trade-offs to better enable personalized therapeutic decision-making.

Empagliflozin and risk of lower respiratory tract infection in heart failure with mildly reduced and preserved ejection fraction: An EMPEROR-Preserved analysis.

AIMS: Lower respiratory tract infections (LRTI) are common worldwide. Patients with heart failure and mildly reduced or preserved ejection fraction (HFmrEF/HFpEF) have a high risk of developing LRTI. Prior studies were able to show that sodium-glucose cotransporter 2 inhibitors may reduce the incidence of LRTI in patients with type 2 diabetes. The aim of this study was to evaluate patient characteristics and prognosis according to LRTI status and to assess the effect of empagliflozin on LRTI in 5988 patients with HFmrEF/HFpEF enrolled in the EMPEROR-Preserved trial randomized to either empagliflozin or placebo over a median follow-up of 26 months. METHODS AND RESULTS: Time-updated models were used to study the mortality risk after a LRTI. Cox regression was used to study the effect of empagliflozin on incident LRTI. Throughout the follow-up, 699 of 5988 (11.7%) patients developed LRTI: these were older, were more frequently hospitalized within the previous year, had type 2 diabetes, chronic kidney disease, and had higher N-terminal pro-B-type natriuretic peptide levels than patients without incident LRTI. Patients who developed LRTI had a 2.7-fold higher risk of subsequent mortality compared to patients without LRTI. The incidence of LRTI was 5.2 (95% confidence interval [CI] 4.6-5.8) events per 100 person-years in the empagliflozin group and 6.2 (95% CI 5.6-6.9) events per 100 person-years in the placebo group (hazard ratio 0.83, 95% CI 0.71-0.96, p = 0.014). The total number of LRTI events was reduced in the empagliflozin group (incidence rate ratio 0.80, 95% CI 0.68-0.94, p = 0.008). No effect of empagliflozin was observed on COVID-19 incidence. CONCLUSION: In EMPEROR-Preserved, LRTI was frequent and associated with a poor prognosis. Empagliflozin was associated with a reduced risk of LRTI compared to placebo.

Impact of empagliflozin on first and recurrent events leading to or prolonging hospitalisation in the EMPA-REG OUTCOME trial.

In EMPA-REG OUTCOME, empagliflozin reduced the composite of total events leading to/prolonging hospitalisation for any cause and all-cause mortality by 24 % versus placebo in patients with T2DM and ASCVD, with 67.7 events prevented/1000 patient-years and a low NNT. Effects were sustained and were consistent regardless of the reason for hospitalisation.

One-month DAPT with ticagrelor and aspirin for patients undergoing coronary artery bypass grafting: rationale and design of the randomised, multicentre, double-blind, placebo-controlled ODIN trial.

The optimal antiplatelet strategy after coronary artery bypass graft (CABG) surgery in patients with chronic coronary syndromes (CCS) is unclear. Adding the P2Y12 inhibitor, ticagrelor, to low-dose aspirin for 1 year is associated with a reduction in graft failure, particularly saphenous vein grafts, at the expense of an increased risk of clinically important bleeding. As the risk of thrombotic graft failure and ischaemic events is highest early after CABG surgery, a better risk-to-benefit profile may be attained with short-term dual antiplatelet therapy followed by single antiplatelet therapy. The One Month Dual Antiplatelet Therapy With Ticagrelor in Coronary Artery Bypass Graft Patients (ODIN) trial is a prospective, randomised, double-blind, placebo-controlled, international, multicentre study of 700 subjects that will evaluate the effect of short-term dual antiplatelet therapy with ticagrelor plus low-dose aspirin after CABG in patients with CCS. Patients will be randomised 1:1 to ticagrelor 90 mg twice daily or matching placebo, in addition to aspirin 75-150 mg once daily for 1 month; after the first month, antiplatelet therapy will be continued with aspirin alone. The primary endpoint is a hierarchical composite of all-cause death, stroke, myocardial infarction, revascularisation and graft failure at 1 year. The key secondary endpoint is a hierarchical composite of all-cause death, stroke, myocardial infarction, Bleeding Academic Research Consortium (BARC) type 3 bleeding, revascularisation and graft failure at 1 year (net clinical benefit). ODIN will report whether the addition of ticagrelor to low-dose aspirin for 1 month after CABG reduces ischaemic events and provides a net clinical benefit in patients with CCS.

Early changes in estimated glomerular filtration rate post-initiation of empagliflozin in EMPEROR-Preserved.

AIMS: Renal function (estimated glomerular filtration rate [eGFR]) changes early after the introduction of empagliflozin have not been described in heart failure with preserved ejection fraction (HFpEF). The aim of this study was to describe early eGFR changes, assess its determinants and its clinical impact on cardiovascular and renal outcomes in patients with HFpEF enrolled in EMPEROR-Preserved. METHODS AND RESULTS: Estimated glomerular filtration rate changes (absolute and relative) from randomization to week 4 were calculated and landmark analyses performed. Initial eGFR change was available in 5836 patients (97.5% of the population). Empagliflozin induced a mean eGFR change of -3.2 ml/min/1.73 m2 versus placebo from baseline to week 4. After week 4, in the empagliflozin group, the risk of the primary outcome (composite of heart failure hospitalization or cardiovascular death), cardiovascular, all-cause mortality and sustained ≥50% eGFR decrease or end-stage renal disease (ESRD) did not differ by eGFR change levels. In contrast, in the placebo group, patients included in the tertile with most profound eGFR decrease (i.e. ≥5.1% from baseline) had a higher risk of the primary outcome (hazard ratio [HR] 1.46, 95% confidence interval [CI] 1.17-1.82), cardiovascular mortality (HR 1.38, 95% CI 1.01-1.89) and sustained ≥50% eGFR decrease or ESRD (HR 2.20, 95% CI 1.20-4.04) versus tertile with eGFR increase. CONCLUSION: An initial relatively small eGFR decrease may be expected after empagliflozin initiation. Such small eGFR decrease was not associated with adverse cardiovascular outcomes with empagliflozin. In contrast, eGFR decrease was associated with poor cardiovascular outcomes with placebo.

Body mass index and cardiorenal outcomes in the EMPEROR-Preserved trial: Principal findings and meta-analysis with the DELIVER trial.

AIMS: Both low and high body mass index (BMI) are associated with poor heart failure outcomes. Whether BMI modifies benefits of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in heart failure with preserved ejection fraction (HFpEF) requires further investigation. METHODS AND RESULTS: Using EMPEROR-Preserved data, the effects of empagliflozin versus placebo on the risks for the primary outcome (hospitalization for heart failure [HHF] or cardiovascular [CV] death), change in estimated glomerular filtration rate (eGFR) slopes, change in Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS), and secondary outcomes across baseline BMI categories (<25 kg/m2, 25 to <30 kg/m2, 30 to <35 kg/m2, 35 to <40 kg/m2 and ≥40 kg/m2) were examined, and a meta-analysis conducted with DELIVER. Forty-five percent had a BMI of ≥30 kg/m2. For the primary outcome, there was a consistent treatment effect of empagliflozin versus placebo across the BMI categories with no formal interaction (p trend = 0.19) by BMI categories. There was also no difference in the effects on secondary outcomes including total HHF (p trend = 0.19), CV death (p trend = 0.20), or eGFR slope with slower declines with empagliflozin regardless of BMI (range 1.12-1.71 ml/min/1.73 m2 relative to placebo, p trend = 0.85 for interaction), though there was no overall impact on the composite renal endpoint. The difference in weight change between empagliflozin and placebo was -0.59, -1.48, -1.54, -0.87, and - 2.67 kg in the lowest to highest BMI categories (p trend = 0.016 for interaction). A meta-analysis of data from EMPEROR-Preserved and DELIVER showed a consistent effect of SGLT2i versus placebo across BMI categories for the outcome of HHF or CV death. There was a trend toward greater absolute KCCQ-CSS benefit at 32 weeks with empagliflozin at higher BMIs (p = 0.08). CONCLUSIONS: Empagliflozin treatment resulted in broadly consistent cardiac effects across the range of BMI in patients with HFpEF. SGLT2i treatment yields benefit in patients with HFpEF regardless of baseline BMI.

Results of the COMPASS Trial Analyzed Using Win Ratio Compared With Conventional Analytic Approaches.

BACKGROUND: Win ratio (WR) is a newer analytic approach for trials with composite end points that accounts for the relative importance of individual components. Our objective was to compare the results of the Cardiovascular Outcomes for People Using Anticoagulation Strategies (COMPASS) trial analyzed using WR with those obtained using conventional statistical approaches. METHODS: We used an unmatched WR analysis for first and total (first plus recurrent) events to examine effects of rivaroxaban with aspirin and rivaroxaban alone vs aspirin alone on primary efficacy (cardiovascular death, stroke, myocardial infarction), safety (modified International Society on Thrombosis and Haemostasis major bleeding), and net clinical benefit (primary efficacy plus fatal or critical organ bleeding) end points. We compared the WR results with those obtained using the Cox proportional hazards regression model for first events and Anderson-Gill method for total events. We calculated the win difference to estimate absolute treatment effects. RESULTS: The WR approach produced results consistent with those obtained using conventional statistical methods for the primary composite end point (first event: WR, 1.32 [95% confidence interval (CI), 1.14-1.52]; 1/Cox hazard ratio, 1.32 [95% CI, 1.16-1.52]; total [first plus recurrent] events: WR, 1.32 [95% CI, 1.14-1.52]; 1/Anderson-Gill hazard ratio, 1.32 [95% CI, 1.16-1.54]) as well as for main safety and net clinical benefit end points. The absolute benefits of the combination of rivaroxaban and aspirin compared with aspirin alone calculated using the win difference were greatest in those with multiple high-risk features. CONCLUSIONS: Reanalysis of the COMPASS trial results using WR produced results that were consistent with those obtained using conventional statistical approaches.

Insulin-like growth factor binding protein-7 concentrations in chronic heart failure: Results from the EMPEROR programme.

AIMS: Insulin-like growth factor binding protein-7 (IGFBP7) is a biomarker of tissue senescence with a role in cardio-renal pathophysiology. The role of IGFBP7 as a prognostic biomarker across the full ejection fraction (EF) spectrum of heart failure (HF) remains less well understood. We examined associations between IGFBP7 and risk of cardio-renal outcomes regardless of EF and the effect of empagliflozin treatment on IGFBP7 concentrations among individuals with HF. METHODS AND RESULTS: IGFBP7 was measured in 1125 study participants from the EMPEROR-Reduced and EMPEROR-Preserved trials. Cox regression was used to study associations with outcomes. Study participants with IGFBP7 levels in the highest tertile had a higher-risk clinical profile. In Cox proportional hazards models adjusted for clinical variables, N-terminal pro-B-type natriuretic peptide and high-sensitivity cardiac troponin T, baseline IGFBP7 values in the highest tertile predicted an increased risk of HF hospitalization or cardiovascular death (hazard ratio [HR] 2.00, 95% confidence interval [CI] 1.28-3.10, p = 0.002, p for trend <0.001) and higher risk of the renal composite endpoint (HR 4.66, 95% CI 1.61-13.53, p = 0.005, p for trend = 0.001), regardless of EF. Empagliflozin reduced risk for cardiovascular death/HF hospitalization irrespective of baseline IGFBP7 (p for trend across IGFBP7 tertiles = 0.26). Empagliflozin treatment was not associated with meaningful change in IGFBP7 at 12 or 52 weeks. CONCLUSION: Across the entire left ventricular EF spectrum in the EMPEROR Programme, concentrations of the senescence-associated biomarker IGFBP7 were associated with higher risk clinical status and predicted adverse cardio-renal outcomes even in models adjusted for conventional biomarkers. Empagliflozin did not significantly affect IGFBP7 levels over time.

Carbohydrate antigen 125 concentrations across the ejection fraction spectrum in chronic heart failure: The EMPEROR programme.

AIM: Vascular congestion may lead to an increase of carbohydrate antigen 125 (CA-125). The role of CA-125 as a biomarker of congestion or for prognosis across the full ejection fraction (EF) spectrum of chronic heart failure (HF) remains unknown. METHODS AND RESULTS: Serum CA-125 was measured in 1111 study participants from the EMPEROR-Reduced and EMPEROR-Preserved trials. Congestive signs and symptoms were evaluated across CA-125 tertiles. Cox regression was used to study the association with outcomes. The primary outcome was a composite of first HF hospitalization or cardiovascular (CV) death. No significant association was present between baseline CA-125 levels and congestive signs or symptoms. In the overall population, higher CA-125 levels were not associated with an increased risk of primary outcome (tertile 3 vs. tertile 1: hazard ratio [HR] 1.34; 95% confidence interval [CI] 0.91-1.96; p-trend = 0.11). However, higher CA-125 levels were associated with an increased risk of primary outcome in patients with HF and reduced EF (HFrEF; tertile 3 vs. tertile 1: HR 2.25 [95% CI 1.30-3.89]), but not among patients with preserved EF (HFpEF; tertile 3 vs. tertile 1: HR 0.68 [95% CI 0.38-1.21]); interaction-p = 0.02). Patients in the upper CA-125 tertile also showed the steepest estimated glomerular filtration rate decline over time (p-trend = 0.03). The effect of empagliflozin to reduce the risk of CV death or HF hospitalization appeared to be attenuated in those with lower baseline CA-125 levels (interaction-p-trend = 0.09). CONCLUSION: Across the range of EF in patients with chronic HF enrolled in the EMPEROR trials, the majority of whom did not have clinical evidence of congestion, CA-125 concentrations were not significantly associated with congestive signs or symptoms. CA-125 concentrations may predict HF hospitalization/CV death in patients with HFrEF, but not those with HFpEF.

Impact of Antihypertensive Medication Changes After Renal Denervation Among Different Patient Groups: SPYRAL HTN-ON MED.

BACKGROUND: The SPYRAL HTN-ON MED (Global Clinical Study of Renal Denervation With the Symplicity Spyral Multi-electrode Renal Denervation System in Patients With Uncontrolled Hypertension in the Absence of Antihypertensive Medications)trial showed significant office and nighttime systolic blood pressure (BP) reductions in patients with hypertension following renal denervation (RDN) compared with sham-control patients, despite similar 24-hour BP reductions. We compared antihypertensive medication and BP changes among prespecified subpopulations. METHODS: The multicenter, randomized, sham-controlled, blinded SPYRAL HTN-ON MED trial (n=337) evaluated BP changes after RDN compared with a sham procedure in patients with hypertension prescribed 1 to 3 antihypertensive drugs. Most patients (n=187; 54%) were enrolled outside the United States, while 156 (46%) US patients were enrolled, including 60 (18%) Black Americans. RESULTS: Changes in detected antihypertensive drugs were similar between RDN and sham group patients in the outside US cohort, while drug increases were significantly more common in the US sham group compared with the RDN group. Patients from outside the United States showed significant reductions in office and 24-hour mean systolic BP at 6 months compared with the sham group, whereas BP changes were similar between RDN and sham in the US cohort. Within the US patient cohort, Black Americans in the sham control group had significant increases in medication burden from baseline through 6 months (P=0.003) but not in the RDN group (P=0.44). CONCLUSIONS: Patients enrolled outside the United States had minimal antihypertensive medication changes between treatment groups and had significant office and 24-hour BP reductions compared with the sham group. Increased antihypertensive drug burden in the US sham cohort, especially among Black Americans, may have diluted the treatment effect in the combined trial population.

Incremental value of C-reactive protein to the MEESSI acute heart failure risk score.

AIMS: We hypothesized that the current gold standard for risk stratification of patients with acute heart failure (AHF), the Multiple Estimation of risk based on the Emergency department Spanish Score In patients with AHF (MEESSI-AHF) risk score, can be further improved by adding systemic inflammation as quantified by C-reactive protein (CRP). METHODS AND RESULTS: In a prospective multicentre diagnostic study (BASEL V), AHF was centrally adjudicated by two independent cardiologists. The MEESSI-AHF risk score was calculated using an established reduced and recalibrated model containing 12 independent risk factors. Model extension was performed by refitting and adding CRP in the logistic regression model with 30-day mortality as binary outcome. Discrimination, calibration and clinical usefulness were used to assess the performance of the extended Multiple Estimation of risk based on the Emergency department Spanish Score In patients (MEESSI) model. Validation was performed in an independent, retrospective and single-centre AHF cohort. Among 1208 AHF patients with complete data allowing calculation of the recalibrated MEESSI and the extended MEESSI models, the prognostic accuracy for 30-day mortality of the extended MEESSI model (c-statistic 0.83, 95% confidence interval [CI] 0.79-0.87) was significantly higher compared to the recalibrated model (c-statistic 0.79, 95% CI 0.75-0.83, p = 0.013). The extended model allowed to stratify a higher percentage of patients into the lowest risk group compared to the recalibrated model (33.1% vs. 20.3%). Demonstrating a calibration plot's slope of 1.00 (95% CI 0.81-1.19) and an intercept of 0.0 (95% CI -0.22 to 0.22), the extended MEESSI model achieved excellent and improved calibration. Results were confirmed in the independent validation cohort (n = 575). CONCLUSIONS: Quantifying inflammation using CRP concentration provided incremental value in AHF risk stratification using the established MEESSI model.

Effect of Reconstituted Human Apolipoprotein A-I on Recurrent Ischemic Events in Survivors of Acute MI.

BACKGROUND: The AEGIS-II trial hypothesized that CSL112, an intravenous formulation of human apoA-I, would lower the risk of plaque disruption, decreasing the risk of recurrent events such as myocardial infarction (MI) among high-risk patients with MI. OBJECTIVES: This exploratory analysis evaluates the effect of CSL112 therapy on the incidence of cardiovascular (CV) death and recurrent MI. METHODS: The AEGIS-II trial was an international, multicenter, randomized, double-blind, placebo-controlled trial that randomized 18,219 high-risk acute MI patients to 4 weekly infusions of apoA-I (6 g CSL112) or placebo. RESULTS: The incidence of the composite of CV death and type 1 MI was 11% to 16% lower in the CSL112 group over the study period (HR: 0.84; 95% CI: 0.7-1.0; P = 0.056 at day 90; HR: 0.86; 95% CI: 0.74-0.99; P = 0.048 at day 180; and HR: 0.89; 95% CI: 0.79-1.01; P = 0.07 at day 365). Similarly, the incidence of CV death or any MI was numerically lower in CSL112-treated patients throughout the follow-up period (HR: 0.92; 95% CI: 0.80-1.05 at day 90, HR: 0.89; 95% CI: 0.79-0.996 at day 180, HR: 0.91; 95% CI: 0.83-1.01 at day 365). The effect of CSL112 treatment on MI was predominantly observed for type 1 MI and type 4b (MI due to stent thrombosis). CONCLUSIONS: Although CSL112 did not significantly reduce the occurrence of the primary study endpoints, patients treated with CSL112 infusions had numerically lower rates of CV death and MI, type-1 MI, and stent thrombosis-related MI compared with placebo. These findings could suggest a role of apoA-I in reducing subsequent plaque disruption events via enhanced cholesterol efflux. Further prospective data would be needed to confirm these observations.

Comparing the long-term outcomes in chronic coronary syndrome patients with prior ST-segment and non-ST-segment elevation myocardial infarction: findings from the TIGRIS registry.

OBJECTIVES: Compared with ST-segment elevation myocardial infarction (STEMI) patients, non-STEMI (NSTEMI) patients have more comorbidities and extensive coronary artery disease. Contemporary comparative data on the long-term prognosis of stable post-myocardial infarction subtypes are needed. DESIGN: Long-Term rIsk, clinical manaGement and healthcare Resource utilisation of stable coronary artery dISease (TIGRIS) was a multinational, observational and longitudinal cohort study. SETTING: Patients were enrolled from 350 centres, with >95% coming from cardiology practices across 24 countries, from 19 June 2013 to 31 March 2017. PARTICIPANTS: This study enrolled 8277 stable patients 1-3 years after myocardial infarction with ≥1 additional risk factor. OUTCOME MEASURES: Over a 2 year follow-up, cardiovascular events and deaths and self-reported health using the EuroQol 5-dimension questionnaire score were recorded. Relative risk of clinical events and health resource utilisation in STEMI and NSTEMI patients were compared using multivariable Poisson regression models, adjusting for prognostically relevant patient factors. RESULTS: Of 7752 patients with known myocardial infarction type, 46% had NSTEMI; NSTEMI patients were older with more comorbidities than STEMI patients. NSTEMI patients had significantly poorer self-reported health and lower prevalence of dual antiplatelet therapy at hospital discharge and at enrolment 1-3 years later. NSTEMI patients had a higher incidence of combined myocardial infarction, stroke and cardiovascular death (5.6% vs 3.9%, p<0.001) and higher all-cause mortality (4.2% vs 2.6%, p<0.001) compared with STEMI patients. Risks were attenuated after adjusting for other patient characteristics. Health resource utilisation was higher in NSTEMI patients, although STEMI patients had more cardiologist visits. CONCLUSIONS: Post-NSTEMI chronic coronary syndrome patients had a less favourable risk factor profile, poorer self-reported health and more adverse cardiovascular events during long-term follow-up than individuals post STEMI. Efforts are needed to recognise the risks of stable patients after NSTEMI and optimise secondary prevention and care. TRIAL REGISTRATION NUMBER: NCT01866904.

Eventos adversos en pacientes con insuficiencia cardiaca aguda clasificados de bajo riesgo por la escala MEESSI y dados de alta desde urgencias: cuantificación y predictibilidad / Patients with acute heart failure discharged from the emergency department and classified as low risk by the MEESSI score (multiple risk estimate based on the Spanish emergency department scale): prevalence of adverse events and predictability

Objetivo: Investigar la tasa de eventos adversos en pacientes con insuficiencia cardiaca aguda (ICA) clasificados de bajo riesgo por la escala MEESSI y dados de alta desde urgencias, la capacidad discriminativa de dicha escala para estos eventos en dichos pacientes y las variables asociadas. Método: Se estratificó el riesgo de los pacientes del Registro EAHFE (cohortes 2-5) mediante la escala MEESSI y se analizaron los clasificados de bajo riesgo dados de alta desde urgencias. Se investigó la mortalidad por cualquier causa a 30 días (M-30d), la revisita a urgencias por ICA a 7 días (REV-7d) y la revisita a urgencias u hospitalización por ICA a 30 días (REV-H-30d). Se calculó el área bajo la curva (ABC) de la característica operativa del receptor (COR) de la escala MEESSI para estos eventos. Se analizó la relación entre 42 variables y RV-7d y RV-H-30d mediante regresión logística multivariable. Resultados: Se incluyeron 1028 pacientes. La M-30d fue 1,6% (IC 95%: 0,9-2,5), la REV-7d fue 8,0% (6,4-9,8) y la REV-H-30d fue 24,7% (22,1-25,7). El ABC ROC de la puntuación MEESSI para discriminar estos eventos adversos fue 0,69 (0,58-0,80), 0,56 (0,49-0,63) y 0,54 (0,50-0,59), respectivamente. Se asociaron con RV-7d: tratamiento diurético crónico (OR 2,45; 1,01-5,98), hemoglobina < 110 g/L (1,68; 1,02-2,75) y tratamiento diurético intravenoso en urgencias (0,53; 0,31-0,90). Se asociaron con REV-H-30d: arteriopatía periférica (1,74; 1,01-3,00), episodios previos de ICA (1,42; 1,02-1,98), tratamiento crónico con inhibidores de receptores mineralocorticoides (1,71; 1,09-2,67), índice de Barthel en urgencias < 90 puntos (1,48; 1,07-2,06) y tratamiento diurético intravenoso en urgencias (0,58; 0,40-0,84). Conclusiones: Los pacientes con ICA de bajo riesgo dados de alta desde urgencias presentan tasas de eventos adversos cercanas a los estándares recomendados internacionalmente. La escala MEESSI, diseñada para predecir M-30d, tiene escasa capacidad predictiva para REV-7d y REV-H-30d en los pacientes de bajo riesgo. Este estudio describe otros factores asociados a tales eventos

Objective: To determine the rate of adverse events in patients with acute heart failure (AHF) who were discharged from the emergency department (ED) after classification as low risk according to MEESSI score (multiple risk estimate based on the Spanish ED scale), to analyze the ability of the score to predict events, and to explore variables associated with adverse events. Methods: Patients in the EAHFE registry (Epidemiology of Acute Heart Failure in EDs) were stratified according to risk indicated by MEESSI score in order to identify those considered at low risk on discharge. All-cause 30-day mortality and revisits related to AHF within 7 days and 30 days were recorded. The area under the receiver operating characteristic curve (AUC) was calculated for the MEESSI score's ability to predict these events. Associations between 42 variables and 7-day and 30-day revisits to the ED were analyzed by multivariable logistic regression. Results: A total of 1028 patients were included. The 30-day mortality rate was 1.6% (95% CI, 0.9%-2.5%). The 7-day and 30-day revisit rates were 8.0% (95% CI, 6.4%-9.8%) and 24.7% (95% CI, 22.1%-25.7%), respectively. The AUCs for MEESSI score discrimination between patients with and without these outcomes were as follows: 30-day mortality, 0.69 (95% CI, 0.58-0.80); 7-day revisiting, 0.56 (95% CI, 0.49-0.63); and 30-day revisiting, 0.54 (95% CI, 0.50-0.59). Variables associated with 7-day revisits were long-term diuretic treatment (odds ratio [OR], 2.45; 95% CI, 1.01-5.98), hemoglobin concentration less than 110 g/L (OR, 1.68; 95% CI, 1.02-2.75), and intravenous diuretic treatment in the ED (OR, 0.53; 95% CI, 0.31-0.90). Variables associated with 30-day revisits were peripheral artery disease (OR, 1.74; 95% CI, 1.01-3.00), prior history of an AHF episode (OR, 1.42; 95% CI, 1.02-1.98), long-term mineralocorticoid receptor antagonist treatment (OR, 1.71; 95% CI, 1.09-2.67), Barthel index less than 90 points in the ED (OR, 1.48; 95% CI, 1.07-2.06), and intravenous diuretic treatment in the ED (OR, 0.58; 95% CI, 0.40-0.84). Conclusions: Patients with AHF who are at low risk for adverse events on discharge from our EDs have event rates that are near internationally recommended targets. The MEESSI score, which was designed to predict 30-day mortality, is a poor predictor of 7-day or 30-day revisiting in these low-risk patients. We identified other factors related to these events

Utilidad de la escala MEESSI para la estratificación del riesgo de pacientes con insuficiencia cardiaca aguda en servicios de urgencias / The usefulness of the MEESSI score for risk stratification of patients with acute heart failure at the emergency department

Introducción y objetivos: En los servicios de urgencias hospitalarios(SUH), la escala MEESSI estratifica a los pacientes diagnosticados de insuficiencia cardiaca aguda(ICA) según su riesgo de mortalidad a 30 días. Se valida la escala de riesgo MEESSI en una nueva cohorte de pacientes para evaluar su precisión al estratificar el riesgo y compararla en diferentes entornos. Métodos: Se incluyó a los pacientes consecutivos diagnosticados de ICA en 30 SUH durante enero y febrero de 2016. Se calculó la puntuación MEESSI de cada paciente. El estadístico C midió la capacidad discriminatoria para predecir la mortalidad a 30 días del modelo MEESSI completo y los modelos secundarios. Se realizaron comparaciones entre los subgrupos de pacientes de hospitales universitarios y comunitarios, de SUH con actividad alta, media o baja y de SUH que reclutaron o que no reclutaron a pacientes de la cohorte original de derivación de la escala MEESSI. Resultados: Se analizó a 4.711 pacientes (hospitales universitarios/comunitarios: 3.811/900; SUH alta/media/baja actividad: 2.695/1.479/537; SUH participantes/no participantes en el estudio de derivación original:3.892/819). La distribución de pacientes según las categorías de riesgo de la escala MEESSI fue: 1.673 (35,5%) de bajo riesgo, 2.023 (42,9%) de riesgo intermedio, 530 (11,3%) de alto riesgo y 485 (10,3%) de muy alto riesgo, con mortalidades a 30 días del 2,0, el 7,8, el 17,9 y el 41,4% respectivamente. El estadístico C para el modelo completo fue 0,810 (IC95%, 0,790-0,830) y varió de 0,731 a 0,785 para los modelos secundarios. La capacidad discriminatoria de la escala de riesgo MEESSI fue similar entre los subgrupos de hospitales, entre SUH de distinta actividad y entre hospitales reclutadores originales y nuevos. Conclusiones: La escala MEESSI estratifica con éxito a los pacientes con ICA en los SUH según el riesgo de muerte a 30días, lo cual puede ayudar en urgencias a la toma de decisiones sobre el destino de estos pacientes

Introduction and objectives: The MEESSI scale stratifies acute heart failure (AHF) patients at the emergency department (ED) according to the 30-day mortality risk. We validated the MEESSI risk score in a new cohort of Spanish patients to assess its accuracy in stratifying patients by risk and to compare its performance in different settings. Methods: We included consecutive patients diagnosed with AHF in 30 EDs during January and February 2016. The MEESSI score was calculated for each patient. The c-statistic measured the discriminatory capacity to predict 30-day mortality of the full MEESSI model and secondary models. Further comparisons were made among subgroups of patients from university and community hospitals, EDs with high-, medium-or low-activity and EDs that recruited or not patients in the original MEESSI derivation cohort. Results: We analyzed 4711 patients (university/community hospitals: 3811/900; high-/medium-/low-activity EDs: 2695/1479/537; EDs participating/not participating in the previous MEESSI derivation study: 3892/819). The distribution of patients according to the MEESSI risk categories was: 1673 (35.5%) low risk, 2023 (42.9%) intermediate risk, 530 (11.3%) high risk and 485 (10.3%) very high risk, with 30-day mortality of 2.0%, 7.8%, 17.9%, and 41.4%, respectively. The c-statistic for the full model was 0.810 (95%CI, 0.790-0.830), ranging from 0.731 to 0.785 for the subsequent secondary models. The discriminatory capacity of the MEESSI risk score was similar among subgroups of hospital type, ED activity, and original recruiter EDs. Conclusions: The MEESSI risk score successfully stratifies AHF patients at the ED according to the 30-day mortality risk, potentially helping clinicians in the decision-making process for hospitalizing patients
