Glycoprotein IIb/IIIa inhibitor use in cardiogenic shock complicating myocardial infarction: The Portuguese Registry of Acute Coronary Syndromes.

INTRODUCTION AND OBJECTIVES: Cardiogenic shock (CS) complicates 5-10% of cases of myocardial infarction (MI). Whether glycoprotein IIb/IIIa inhibitors (GPIs) are beneficial in these patients is controversial. Our aim is to assess the prognostic impact of GPI use on in-hospital mortality and outcomes in patients with MI and CS undergoing percutaneous coronary intervention (PCI). METHODS: Between October 2010 and December 2019, 27578 acute coronary syndrome (ACS) patients were included in the multicenter Portuguese Registry of Acute Coronary Syndromes. Of these, 357 with an MI complicated by CS were included in the analysis and grouped based on whether they received GPI therapy (with GPI, n=107 and without GPI, n=250). The primary endpoint was in-hospital mortality. Secondary endpoints included successful PCI and in-hospital reinfarction and major bleeding. RESULTS: Demographics and cardiovascular risk factors did not differ between groups. ST-elevation MI patients were more likely to receive GPIs (95% vs. 83%, p=0.002). In-hospital mortality was similar between groups (OR 1.80, 95% CI 0.96-3.37). Only age and the use of inotropes or intra-aortic balloon pump were predictors of mortality. Also, no differences between groups were noted for successful PCI (OR 0.33, 95% CI 0.62-4.06), reinfarction (OR 0.77, 95% CI 0.15-3.90), or major bleeding (OR 1.68, 95% CI 0.75-3.74). CONCLUSION: The use of GPIs in the context of MI with CS did not significantly impact in-hospital outcomes.

Aortic valve intervention for aortic stenosis and cardiac amyloidosis: a systematic review and meta-analysis.

Aortic stenosis with cardiac amyloidosis (CA-AS) is common in the elderly. We provide an overview and a meta-analysis of outcomes after aortic valve (AV) intervention. The primary end point was all-cause mortality. Weighted pooled analysis showed a non-significant higher risk of death in CA-AS patients following surgical or transcatheter AV replacement. After transcatheter AV replacement, the risk of death in CA-AS patients was comparable to that associated with aortic stenosis alone (risk ratio: 1.23; 95% CI: 0.77-1.96; p = 0.39; I2 = 0%). An AV intervention is possibly not futile in CA-AS and should not be denied to patients with this condition.

Dual presentation of aortic stenosis (AS) and cardiac amyloidosis (CA) is common in the elderly. Patients with CA-AS face a dismal prognosis. Clinical outcomes after an aortic valve intervention are conflicting. Our data showed that there is no increased risk of death in CA-AS patients compared with patients with only AS after an aortic valve replacement. In particular, our analysis unveils that following less invasive percutaneous aortic valve replacement, rates of death of patients with concomitant CA were not significantly different from those in patients who had AS without CA. Based on this data, an aortic valve substitution procedure should not be withheld in patients with CA.

Computed tomography coronary angiography as the noninvasive in stable coronary artery disease? Long-term outcomes meta-analysis.

Aim: To compare outcomes of coronary computed tomography angiography (CCTA) with that of functional testing (FT) in stable coronary artery disease. Methods: We searched PubMed, Embase, and Cochrane for randomized controlled trials (RCTs). A random-effects meta-analysis targeting all-cause death and nonfatal acute coronary syndromes was performed. Results: Eight RCTs enrolling 29,579 patients were included. Pooled relative risk (RR) for the primary end point was similar between CCTA and FT (RR = 0.97; 95% CI: 0.76-1.22). CCTA outperformed FT in nonfatal myocardial infarction (MI) (RR = 0.59; 95% CI: 0.41-0.83) and in downstream testing (OR: 0.47; 95% CI: 0.21-1.01). Conclusion: Updated data of stable coronary artery disease suggests that CCTA improved nonfatal MI and downstream testing.

Coronary heart disease (narrowed or blocked arteries) can be diagnosed either by a functional testing or an anatomic testing. In functional testing, we will see if there is some reduced blood flow in the heart. In anatomic testing, a computerized tomography coronary angiogram is performed, to see the presence of atherosclerotic plaque (cholesterol) and the degree of obstruction. In this review, we provide an aerial view of the latest evidence on the best approach to coronary artery disease diagnosis. Updated evidence shows that a computerized tomography coronary angiogram reduced the risk of myocardial infarction and the need of further testing after an initial approach.

Chronic kidney disease in acute coronary syndromes: real-world data of long-term outcomes.

Aim: Patients with chronic kidney disease (CKD) are at increased cardiovascular risk. Methods: Patients with acute coronary syndrome were retrospectively allocated to three groups (stage 3A, stage 3B or stage 4) based on the Kidney Disease Improving Global Outcomes classification formulas: the CKD Epidemiology Collaboration (CKD-EPI; N = 401) and the modification of diet in renal disease (n = 355). The primary end point was all-cause mortality (median follow-up time, 32 months [15-70]). Results: Study results showed decreased median survival was associated with poor renal function for both the CKD-EPI (78 vs 61 vs 40 months, p = 0.014) and modification of diet in renal disease groups (68 vs 57 vs 32 months, p = 0.006). After adjustment, age (OR: 1.07; 95% CI: 1.01-1.14) and pulmonary artery systolic pressure (OR: 1.08; 95% CI: 1.03-1.14), but not estimated glomerular filtration rate, were associated with decreased survival. Conclusion: Study results suggest that poor outcomes after an acute coronary syndrome were associated with comorbidities rather than estimated glomerular filtration rate level.

Lay abstract Patients with chronic kidney failure have an elevated risk of heart attack or death. We studied patients with kidney failure and concurrent heart attack for 32 months (median). Our results suggest that poorer renal function was associated with an increased risk of death. However, the most important factors associated with survival were patient age and pulmonary artery systolic pressure and not the particular kidney function. Therefore, in this group of patients, comorbidities appear to play a role as survival determinants.

Left Ventricular Thrombus Therapy With Direct Oral Anticoagulants Versus Vitamin K Antagonists: A Systematic Review and Meta-Analysis.

BACKGROUND: Current guidelines recommend vitamin K antagonists (VKAs) for left ventricular thrombus (LVT) resolution. Direct oral anticoagulants (DOACs) are increasingly evaluated as alternatives to the standard of care in anticoagulation. METHODS: We performed a systematic review and meta-analysis to assess the use of DOACs vs VKAs for LVT treatment. The occurrence of LVT resolution, systemic embolism (SE) or stroke, and bleeding events were compared during follow-up using random-effects analysis. RESULTS: The 5 included studies were all observational (a total of 828 patients). Of these, 284 patients (34%) were treated with DOACs, and 544 (66%) treated with VKAs. Thrombus resolution was similar for both methods (pooled odds ratio [OR], 0.91; 95% CI, 0.47-1.75; I2 = 63%; P = .78). The incidence of SE or stroke was also similar (pooled OR, 1.59; 95% CI, 0.85-2.97; I2 = 0%; P = .14). Clinically relevant bleeding incidence was similar for both groups (pooled OR, 0.66; 95% CI, 0.31-1.40; I2 = 0%; P = .28), although all bleeding events were less frequent in the DOAC group (pooled OR, 0.49; 95% CI, 0.26-0.90; I2 = 0%; P = .02). CONCLUSION: Our systematic review and meta-analysis suggests DOACs were as effective as VKAs for LVT resolution, with a similar risk of systemic embolism/stroke and clinically relevant bleeding. These results, obtained from observational studies, are not definitive and hence randomized controlled trials are needed. Nevertheless, our analysis identifies key experimental features required in future studies.

Glycoprotein IIb/IIIa inhibitors for cardiogenic shock complicating acute myocardial infarction: a systematic review, meta-analysis, and meta-regression.

BACKGROUND: Cardiogenic shock complicates 5-10% of myocardial infarction (MI) cases. Data about the benefit of glycoprotein IIb/IIIa inhibitors (GPI) in these patients is sparse and conflicting. METHODS: We performed a systematic review, meta-analysis, and meta-regression of studies assessing the impact of GPI use in the setting of MI complicated cardiogenic shock on mortality, angiographic success, and bleeding events. We systematically searched for studies comparing GPI use as adjunctive treatment versus standard care in this setting. Random-effects meta-analysis and meta-regression were performed. RESULTS: Seven studies with a total of 1216 patients (GPI group, 720 patients; standard care group, 496 patients) were included. GPI were associated with a 45% relative reduction in the odds of death at 30 days (pooled OR 0.55; 95% CI 0.35-0.85; I2 = 57%; P = 0.007) and a 49% reduction in the odds of death at 1 year (pooled OR 0.51; 95% CI 0.32-0.82; I2 = 58%; P = 0.005). Reduction in short-term mortality seemed to be more important before 2000, as this benefit disappears if only the more recent studies are analyzed. GPI were associated with a 2-fold increase in the probability of achieving TIMI 3 flow (pooled OR, 2.05; 95% CI 1.37-3.05; I2 = 37%, P = 0.0004). Major bleeding events were not increased with GPI therapy (pooled OR, 1.0; 95% CI 0.55-1.83; I2 = 1%, P = 0.99). Meta-regression identified that patients not receiving an intra-aortic balloon pump seemed to benefit the most from GPI use (Z = - 1.57, P = 0.005). CONCLUSION: GPI therapy as an adjunct to standard treatment in cardiogenic shock was associated with better outcomes, including both short- and long-term survival, without increasing the risk of bleeding.

A Spleen Complication After an Acute Myocardial Infarction.

We highlight the potential risk of combined antithrombotic therapy as a rare cause of spontaneous splenic hemorrhage. Conservative management is possible and reintroduction of the antithrombotic therapy is safe after the acute event. (Level of Difficulty: Beginner.).

Psychometric study of the European Portuguese version of the PedsQL 3.0 Cancer Module.

BACKGROUND: Health-related quality of life (HRQoL) is an important outcome to assess the impact of cancer. This article examines the psychometric properties of the European Portuguese self-report version of the Pediatric Quality of Life Inventory™ Cancer Module (PedsQL™ 3.0 Cancer Module) in children and adolescents with cancer. METHODS: The participants, 332 children/adolescents diagnosed with cancer (8-18 years old), completed measures to assess HRQoL (PedsQL™ 3.0 Cancer Module and DISABKIDS Chronic Generic Measure; DCGM-12) and anxiety (Revised Children's Manifest Anxiety Scale - second edition; RCMAS-2). A subsample (n = 52) completed the PedsQL™ 3.0 Cancer Module a second time following one-week. The pediatric oncologists completed the Intensity of Treatment Rating Scale 3.0 (ITR 3.0). RESULTS: For the whole sample, the PedsQL™ 3.0 Cancer Module demonstrated good item discrimination (rs = .30 to .54). The confirmatory factor analysis testing the presence of eight first-order factors loading significantly in a second-order factor revealed an acceptable fit (CFI = .91; RMSEA = .05). The correlation of PedsQL™ 3.0 Cancer Module with DCGM-12 (rs = .17 to .58), and with RCMAS-2 (rs = -.16 to-.51) attested convergent validity. This inventory demonstrated minimally acceptable to very good internal consistency (αs = .65 to .87) and temporal stability (ICCs = .61 to .81). CONCLUSIONS: These findings demonstrate that the European Portuguese self-report version of the PedsQL™ 3.0 Cancer Module is a valid and reliable instrument for assessing HRQoL in pediatric cancer.
