Older patients are underrepresented in prospective studies and randomized clinical trials of acute coronary syndromes (ACS). Over the last decade, a few specific trials have been conducted in this ...population, allowing more evidence-based management. Older adults are a heterogeneous, complex, and high-risk group whose management requires a multidimensional clinical approach beyond coronary anatomic variables. This review focuses on available data informing evidence-based interventional and pharmacological approaches for older adults with ACS, including guideline-directed management. Overall, an invasive approach appears to demonstrate a better benefit-risk ratio compared to a conservative one across the ACS spectrum, even considering patients' clinical complexity and multiple comorbidities. Conversely, more powerful strategies of antithrombotic therapy for secondary prevention have been associated with increased bleeding events and no benefit in terms of mortality reduction. An interdisciplinary evaluation with geriatric assessment should always be considered to achieve a holistic approach and optimize any treatment on the basis of the underlying biological vulnerability.
In the patients on warfarin undergoing percutaneous coronary intervention included in the prospective, multicentre, observational WAR-STENT registry, age ≥75 years was associated with a significant ...increase in in-hospital major bleeding, length of hospitalization, and use of bare-metal stents, with no differences in the peri-procedural management and antithrombotic therapy.
The COVID-19 pandemic has put several healthcare systems under severe pressure. The present analysis investigates how the first wave of the COVID-19 pandemic affected the myocardial infarction (MI) ...network of Emilia-Romagna (Italy).
Based on Emilia-Romagna mortality registry and administrative data from all the hospitals from January 2017 to June 2020, we analysed: i) temporal trend in MI hospital admissions; ii) characteristics, management, and 30-day mortality of MI patients; iii) out-of-hospital mortality for cardiac cause.
Admissions for MI declined on February 22, 2020 (IRR -19.5%, 95%CI from -8.4% to -29.3%, p = 0.001), and further on March 5, 2020 (IRR -21.6%, 95%CI from -9.0% to -32.5%, p = 0.001). The return to pre-COVID-19 MI-related admission levels was observed from May 13, 2020 (IRR 34.3%, 95%CI 20.0%-50.2%, p<0.001). As compared to those before the pandemic, MI patients admitted during and after the first wave were younger and with fewer risk factors. The 30-day mortality remained in line with that expected based on previous years (ratio observed/expected was 0.96, 95%CI 0.84–1.08). MI patients positive for SARS-CoV-2 were few (1.5%) but showed poor prognosis (around 5-fold increase in 30-day mortality). In 2020, the number of out-of-hospital cardiac deaths was significantly higher (ratio observed/expected 1.17, 95%CI 1.08–1.27). The peak was reached in April.
In Emilia-Romagna, MI hospitalizations significantly decreased during the first wave of the COVID-19 pandemic. Management and outcomes of hospitalized MI patients remained unchanged, except for those with SARS-CoV-2 infection. A concomitant increase in the out-of-hospital cardiac mortality was observed.
None.
Combination of oral anticoagulation (OAC) and antiplatelets is used in atrial fibrillation (AF) patients undergoing percutaneous coronary intervention and stent (PCI-S) procedure but is associated ...with increased bleeding when triple antithrombotic therapy (TAT) is used. Our aim was to analyze the impact of time in therapeutic range (TTR) on outcomes, in patients prescribed with TAT.
Ancillary analysis from the AFCAS registry in patients assigned to TAT. TTR was calculated with Rosendaal method. Outcomes were analyzed according to TTR tertiles (T1 ≤56.8% vs. T2 56.9–93.8% vs. T3 ≥93.9%). Major bleeding was the primary outcome.
Of 963 patients enrolled, 470(48.8%) were prescribed with TAT at discharge and qualified for this analysis. Median IQR TTR was 80.0% 45.3–100%. After 359 341–370 days, major bleeding rates were progressively lower with increasing TTR tertiles (T1 vs. T2 vs. T3: 10.3% vs. 4.7% vs. 2.3%, P=.006).
Kaplan–Meier analysis demonstrated a progressively lower risk for major bleeding across tertiles (P=.006). Patients in the highest TTR tertile had a non-significant lower risk for major adverse coronary and cerebrovascular events (MACCE) (log-rank: 4.905, P=.086).
Cox regression analysis showed that T2 and T3 were inversely associated with major bleeding (hazard ratio HR:0.39, P=.050 and HR: 0.21, P=.005). Continuous TTR was inversely associated with major bleeding (HR: 0.98, P<.001). For MACCE, adjusted Cox analysis found a non-significant lower risk for T3 (HR: 0.64, P=.128).
In AF patients undergoing PCI-S prescribed TAT, good quality anticoagulation control (as reflected by TTR) was closely related to bleeding outcomes during follow-up. Despite some suggestive trends for an inverse relationship between TTR and MACCE, no definitive conclusions can be drawn, and further large studies are needed.
Health care is currently showing a fall in heart failure (HF) incidence and prevalence, particularly in developed countries, but with only a subset receiving appropriate therapy to protect the heart ...against maladaptive processes such as fibrosis and hypertrophy. Appropriate markers of advanced HF remain unidentified, which would help in choosing the most suitable therapy and avoid major compliance problems. Speckle tracking echocardiography (STE) is a good choice, being a non-invasive imaging technique which is able to assess cardiac deformation in a variety of conditions. Several multicenter studies and meta-analyses have demonstrated the clinical application and accuracy of STE in early and late stages of HF, as well as its association with both left ventricular (LV) filling pressures and myocardial oxygen consumption. Furthermore, STE assists in assessing right ventricular free-wall longitudinal strain (RVFWLS), which is a solid predictor of right ventricle failure (RVF) following LV assist device (LVAD) implantation. However, STE is known for its limitations; despite these, it has been shown to explain symptoms and signs and also to be an accurate prognosticator. The aim of this review is to examine the advantages of STE in the early evaluation of myocardial dysfunction and its correlation with right heart catheterization (RHC) parameters, which should have significant clinical relevance in the management of HF patients.
Triple therapy (TT) with vitamin K-antagonists (VKA), aspirin and clopidogrel is the recommended antithrombotic treatment following percutaneous coronary intervention with stent implantation (PCI-S) ...in patients with an indication for oral anticoagulation. TT is associated with an increased risk of bleeding, but available evidence is flawed by important limitations, including the limited size and the retrospective design of most of the studies, as well as the rare reporting of the incidence of in-hospital bleeding and the treatment which was actually ongoing at the time of bleeding. Since the perceived high bleeding risk of TT may deny patients effective strategies, the determination of the true safety profile of TT is of paramount importance.
All the 27 published studies where the incidence of bleeding at various time points during follow-up has been reported separately for patients on TT were reviewed, and the weakness of the data was analyzed.
The absolute incidence of major bleeding upon discharge at in-hospital, ≤ 1 month, 6 months, 12 months and ≥ 12 months was: 3.3% ± 1.9%, 5.1% ± 6.7%, 8.0% ± 5.2%, 9.0% ± 8.0, and 6.2% ± 7.8%, respectively, and not substantially different from that observed in previous studies with prolonged dual antiplatelet treatment with aspirin and clopidogrel.
While waiting for the ongoing, large-scale, registries and clinical trials to clarify the few facts and to answer the many questions regarding the risk of bleeding of TT, this treatment should not be denied to patients with an indication for VKA undergoing PCI-S provided that the proper measures and cautions are implemented.
Summary
Even 10 years after the first appearance in the literature of articles reporting on the management of patients on oral anticoagulation (OAC) undergoing percutaneous coronary intervention with ...stent (PCI-S), this issue is still controversial. Nonetheless, some guidance for the everyday management of this patient subset, accounting for about 5–8 % of all patients referred for PCI-S, has been developed. In general, a period of triple therapy (TT) of OAC, with either vitamin K–antagonists (VKA) or non-vitamin K–antagonist oral anticoagulants (NOAC), aspirin, and clopidogrel is warranted, followed by the combination of OAC, and a single antiplatelet agent for up to 12 months, and then OAC alone. The duration of the initial period of TT is dependent on the individual risk of thromboembolism, and bleeding, as well as the clinical context in which PCI-S is performed (elective vs acute coronary syndrome), and the type of stent implanted (bare-metal vs drug-eluting). In this article, we aim to provide a comprehensive, ata- glance, overview of the management strategies, which are currently suggested for the peri-procedural, medium-term, and long-term periods following PCI-S in OAC patients. While acknowledging that most of the evidence has been obtained from patients on OAC because of atrial fibrillation, and with warfarin being the most frequently used VKA, we refer in this overview to the whole population of OAC patients undergoing PCI-S. We refer to the whole population of patients on OAC undergoing PCI-S also when OAC is carried out with NOAC rather than VKA, pointing out, when appropriate, the particular management issues.
