- Trials showing equivalent or better outcomes with initial evaluation using coronary computed tomography angiography (cCTA) compared with stress testing in patients with stable chest pain have informed guidelines but raise questions about overtesting and excess catheterization.To test a modified initial cCTA strategy designed to improve clinical efficiency vs usual testing (UT).This was a pragmatic randomized clinical trial enrolling participants from December 3, 2018, to May 18, 2021, with a median of 11.8 months of follow-up. Patients from 65 North American and European sites with stable symptoms of suspected coronary artery disease (CAD) and no prior testing were randomly assigned 1:1 to precision strategy (PS) or UT.PS incorporated the Prospective Multicenter Imaging Study for the Evaluation of Chest Pain (PROMISE) minimal risk score to quantitatively select minimal-risk participants for deferred testing, assigning all others to cCTA with selective CT-derived fractional flow reserve (FFR-CT). UT included site-selected stress testing or catheterization. Site clinicians determined subsequent care.Outcomes were clinical efficiency (invasive catheterization without obstructive CAD) and safety (death or nonfatal myocardial infarction [MI]) combined into a composite primary end point. Secondary end points included safety components of the primary outcome and medication use.A total of 2103 participants (mean [SD] age, 58.4 [11.5] years; 1056 male [50.2%]) were included in the study, and 422 [20.1%] were classified as minimal risk. The primary end point occurred in 44 of 1057 participants (4.2%) in the PS group and in 118 of 1046 participants (11.3%) in the UT group (hazard ratio [HR], 0.35; 95% CI, 0.25-0.50). Clinical efficiency was higher with PS, with lower rates of catheterization without obstructive disease (27 [2.6%]) vs UT participants (107 [10.2%]; HR, 0.24; 95% CI, 0.16-0.36). The safety composite of death/MI was similar (HR, 1.52; 95% CI, 0.73-3.15). Death occurred in 5 individuals (0.5%) in the PS group vs 7 (0.7%) in the UT group (HR, 0.71; 95% CI, 0.23-2.23), and nonfatal MI occurred in 13 individuals (1.2%) in the PS group vs 5 (0.5%) in the UT group (HR, 2.65; 95% CI, 0.96-7.36). Use of lipid-lowering (450 of 900 [50.0%] vs 365 of 873 [41.8%]) and antiplatelet (321 of 900 [35.7%] vs 237 of 873 [27.1%]) medications at 1 year was higher in the PS group compared with the UT group (both P < .001).An initial diagnostic approach to stable chest pain starting with quantitative risk stratification and deferred testing for minimal-risk patients and cCTA with selective FFR-CT in all others increased clinical efficiency relative to UT at 1 year. Additional randomized clinical trials are needed to verify these findings, including safety.ClinicalTrials.gov Identifier: NCT03702244.

- Elderly patients may have increased platelet reactivity and adverse events after percutaneous coronary intervention. Whether age is an independent predictor of worse outcomes after accounting for platelet reactivity is unknown. We sought to determine the relation between age and platelet reactivity on 2-year outcomes after percutaneous coronary intervention with drug-eluting stents (DES). ADAPT-DES was a prospective observational registry comprising 8,582 DES-treated patients. Patients were categorized with an age cutoff of 75 years. On-clopidogrel platelet reactivity was evaluated with VerifyNow P2Y12 testing. Multivariable Cox proportional hazards regression models were used to describe the relation between increasing age and 2-year clinical outcomes. Patients ≥75 old were more likely to be women and had more cardiovascular risk factors and more extensive coronary artery disease than younger patients. Residual platelet reactivity on-clopidogrel increased slightly with age (adjusted r = 0.05, p <0.0001). Age ≥75 years was associated with greater all-cause mortality (adjusted HR 1.64, 95% CI 1.25 to 2.15, p <0.001), myocardial infarction (adjusted HR 1.33, 95% CI 1.01 to 1.74, p = 0.04) and clinically relevant bleeding (adjusted HR 1.33, 95% CI 1.10 to 1.61 p = 0.003). In contrast, the risk of stent thrombosis was independent of age (adjusted HR 0.83, 95% CI 0.46 to 1.52, and p = 0.55). Considered as a continuous variable, age was directly related to clinically relevant bleeding, cardiac and all-cause mortality, was inversely related to stent thrombosis, and was not related to myocardial infarction. There was no significant interaction between age and on-treatment platelet reactivity for the risk of 2-year clinical outcomes. In conclusion, increasing age had a stronger association with the risk of death and bleeding than of thrombotic events. Despite being associated with older age, higher residual platelet reactivity did not modify the adjusted relative risks of ischemic and bleeding events associated with age.

- The author recently reported ∼50% excess early mortality in patients with first-presentation ST-segment elevation myocardial infarction (STEMI) without standard modifiable cardiovascular risk factors (SMuRFs); the cause of this is not clear.The aim of this study was to examine differences in infarct characteristics and clinical outcomes in patients with versus without SMuRFs (dyslipidemia, hypertension, diabetes mellitus, and smoking).Individual-level data were pooled from 10 randomized percutaneous intervention (PCI) trials in which infarct size was measured within 1 month by either cardiac magnetic resonance or technetium-99m sestamibi single-photon emission computed tomography imaging. First-presentation STEMI was classified into 2 groups according to the presence or absence of at least 1 SMuRF.Among 2,862 patients, 524 (18.3%) were SMuRF-less. After adjusting for study effect, SMuRF-less patients had more frequent poor pre-PCI flow Thrombolysis In Myocardial Infarction 0/1 compared with patients with at least 1 SMuRF (72.0% vs 64.1%; OR: 1.35; 95% CI: 1.08-1.70). There were no independent associations between the presence or absence of SMuRFs at baseline and infarct size (estimate = -0.35; 95% CI: -1.93 to 1.23), left ventricular ejection fraction (estimate = -0.06; 95% CI: -1.33 to 1.20), or mortality at 30 days (HR: 0.46; 95% CI: 0.19-1.07) and 1 year (HR: 0.74; 95% CI: 0.43-1.29).First-presentation STEMI patients with no identifiable baseline SMuRFs had a higher risk of Thrombolysis In Myocardial Infarction flow grade 0/1 pre-PCI. However, after adjustment, there were no significant associations between SMuRF-less status and infarct size, left ventricle ejection fraction, or mortality.

- Severe coronary artery calcification has been associated with stent underexpansion, procedural complications, and increased rates of early and late adverse clinical events in patients undergoing percutaneous coronary intervention. To date, no lesion preparation strategy has been shown to definitively improve outcomes of percutaneous coronary intervention for calcified coronary artery lesions.ECLIPSE (NCT03108456) is a prospective, randomized, multicenter trial designed to evaluate two different vessel preparation strategies in severely calcified coronary artery lesions. The routine use of the Diamondback 360 Coronary Orbital Atherectomy System is compared with conventional balloon angioplasty prior to drug-eluting stent implantation. The trial aims to enroll approximately 2000 subjects with a primary clinical endpoint of target vessel failure, defined as the composite of cardiac death, target vessel-related myocardial infarction, or ischemia-driven target vessel revascularization assessed at 1 year. The co-primary endpoint is the acute post-procedural in-stent minimal cross-sectional area as assessed by optical coherence tomography in a 500-subject cohort. Enrollment is anticipated to complete in 2022 with total clinical follow-up planned for 2 years.ECLIPSE is a large-scale, prospective randomized trial powered to demonstrate whether a vessel preparation strategy of routine orbital atherectomy system is superior to conventional balloon angioplasty prior to implantation of drug-eluting stents in severely calcified coronary artery lesions.

Tidskriftsartikel (refereegranskat)abstract
- Interest in the pathophysiology, etiology, management, and outcomes of patients with tricuspid regurgitation (TR) has grown in the wake of multiple natural history studies showing progressively worse outcomes associated with increasing TR severity, even after adjusting for multiple comorbidities. Historically, isolated tricuspid valve surgery has been associated with high in-hospital mortality rates, leading to the development of transcatheter treatment options. The aim of this first Tricuspid Valve Academic Research Consortium document is to standardize definitions of disease etiology and severity, as well as endpoints for trials that aim to address the gaps in our knowledge related to identification and management of patients with TR. Standardizing endpoints for trials should provide consistency and enable meaningful comparisons between clinical trials. A second Tricuspid Valve Academic Research Consortium document will focus on further defining trial endpoints and will discuss trial design options.

- There are limited data on bivalirudin monotherapy in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) with positive biomarkers of myocardial necrosis (troponin and/or creatine kinase-myocardial band isoenzyme). We sought to evaluate the safety and efficacy of bivalirudin monotherapy in patients with positive biomarkers from the Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial.We compared the net adverse clinical events [composite ischemia - (death, myocardial infarction, or unplanned ischemic revascularization) - or noncoronary artery bypass graft surgery (CABG)-related major bleeding] among patients with biomarker-positive NSTE-ACS in the ACUITY trial overall and by antithrombotic strategy.Among 13 819 patients with NSTE-ACS enrolled in ACUITY, 4728 patients presented with positive biomarkers and underwent an early invasive strategy. Of those, 1547 were randomized to heparin plus a glycoprotein IIb/IIIa inhibitor (GPI), 1555 to bivalirudin plus GPI, and 1626 to bivalirudin monotherapy. Compared with biomarker-negative patients, biomarker-positive patients had higher 30-day rates of net adverse clinical events (14.0 vs. 12.4%; P = 0.04), all-cause death (1.3 vs. 0.5%; P = 0.001), cardiac death (1.1 vs. 0.5%; P = 0.005), and non-CABG-related major bleeding (6.5 vs. 5.2%, P = 0.03). At 30 days, bivalirudin monotherapy was associated with significantly less non-CABG-related major bleeding (bivalirudin monotherapy 4.1% vs. bivalirudin plus GPI 8.4% vs. heparin plus GPI 7.1%) with comparable rates of composite ischemia (bivalirudin monotherapy 9.2% vs. bivalirudin plus GPI 9.9% vs. heparin plus GPI 8.4%). In a multivariable model, bivalirudin monotherapy was associated with a significant reduction in non-CABG-related major bleeding but was not associated with an increased risk of death, myocardial infarction, unplanned revascularization or stent thrombosis.Compared with heparin plus GPI or bivalirudin plus GPI, bivalirudin monotherapy provides similar protection from ischemic events with less major bleeding at 30 days among patients with NSTE-ACS and positive biomarkers.

- Background Use of the modified American College of Cardiology (ACC)/American Heart Association (AHA) lesion classification as a prognostic tool to predict short- and long-term clinical outcomes after percutaneous coronary intervention in the modern drug-eluting stent era is uncertain. Methods and Results Patient-level data from 7 prospective, randomized trials were pooled. Clinical outcomes of patients undergoing single lesion percutaneous coronary intervention with second-generation drug-eluting stent were analyzed according to modified ACC/AHA lesion class. The primary end point was target lesion failure (TLF: composite of cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization). Clinical outcomes to 5 years were compared between patients treated for noncomplex (class A/B1) versus complex (class B2/C) lesions. Eight thousand five hundred sixteen patients (age 63.1±10.8 years, 70.5% male) were analyzed. Lesions were classified as A, B1, B2, and C in 7.9%, 28.5%, 33.7%, and 30.0% of cases, respectively. Target lesion failure was higher in patients undergoing percutaneous coronary intervention of complex versus noncomplex lesions at 30 days (2.0% versus 1.1%, P=0.004), at 1 year (4.6% versus 3.0%, P=0.0005), and at 5 years (12.4% versus 9.2%, P=0.0001). By multivariable analysis, treatment of ACC/AHA class B2/C lesions was significantly associated with higher rate of 5-year target lesion failure (adjusted hazard ratio, 1.39 [95% CI, 1.17-1.64], P=0.0001) driven by significantly higher rates of target vessel myocardial infarction and ischemia-driven target lesion revascularization. Conclusions In this pooled large-scale analysis, treating complex compared with noncomplex lesions according to the modified ACC/AHA classification with second-generation drug-eluting stent was associated with worse 5-year clinical outcomes. This historical classification system may be useful in the contemporary era for predicting early and late outcomes following percutaneous coronary intervention.

Tidskriftsartikel (refereegranskat)abstract
- Mortality after ST-segment elevation myocardial infarction (STEMI) is increased in patients with hypertension. The mechanisms underlying this association are uncertain. We sought to investigate whether patients with STEMI and prior hypertension have greater microvascular obstruction (MVO) and infarct size (IS) compared with those without hypertension.We pooled individual patient data from 7 randomized trials of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) in whom cardiac magnetic resonance imaging was performed within 1 month after reperfusion. The associations between hypertension and MVO, IS, and mortality were assessed in multivariable adjusted models.Among 2174 patients (61.3±12.6 years, 76% male), 1196 (55.0%) had hypertension. Patients with hypertension were older, more frequently diabetic and had more extensive coronary artery disease than those without hypertension. MVO and IS measured as percent LV mass were not significantly different in patients with and without hypertension (adjusted differences 0.1, 95% CI -0.3 to 0.6, p=0.61 and -0.2, 95% CI -1.5 to 1.2, p=0.80, respectively). Hypertension was associated with a higher unadjusted risk of 1-year death (hazard ratio [HR] 2.28, 95% CI 1.44-3.60, p<0.001), but was not independently associated with higher mortality after multivariable adjustment (adjusted HR 1.04, 95% CI 0.60-1.79, p=0.90).In this large-scale individual patient data pooled analysis, hypertension was not associated with larger IS or MVO after primary PCI for STEMI.
