RESUMO
The prognostic relevance of periprocedural myocardial infarction (PMI) in patients with chronic coronary syndrome undergoing percutaneous coronary intervention (PCI) is still matter of debate, particularly regarding the type (cardiac troponin or creatin kinase-MB) and different thresholds of biomarkers elevation, as the importance of associated ancillary criteria of ischemia or concomitant angiographic complications. There are still uncertainties regarding the value of PMI as event which is prognostically equivalent to spontaneous myocardial infarction or if it simply represents a marker of baseline risk, atherosclerotic burden and procedural complexity. In the present review, we will present the mechanisms and predictors of PMI occurring during PCI and potential treatment strategies to reduce its occurrence. We will also overview all commonly adopted definitions of PMI, which carry different prevalence and prognostic implications in daily practice and clinical trials. Finally, we will discuss the impact of different PMI definitions on the interpretation of trials results, emphasizing the importance of adequate endpoints selection in the planning and interpretation of clinical trials.
RESUMO
Background: There is a growing need for percutaneous coronary intervention (PCI) to be performed within the same transcatheter aortic valve implantation (TAVI) procedure. In such cases, cangrelor, a fast-acting intravenous P2Y12-inhibitor with a short offset, is potential clinical utility to minimize bleeding and vascular complications during large-bore arterial access (LBAA) as well as the thrombotic risk associated with concomitant PCI. Case summary: We report two cases of TAVI with an indication to concomitant, high-risk PCI. In the first one, cangrelor was started only after LBAA was secured and TAVI completed, just before the initiation of complex PCI. In the second case, due to predicted complex coronary cannulation after TAVI, complex PCI was performed before TAVI and cangrelor started just after LBAA. In both cases, use of cangrelor (vs. pre-treatment with oral P2Y12-i) allowed for a tailored minimization of the risk of bleeding and vascular complications during LBAA while offering full platelet inhibition during a complex/high-risk PCI. Discussion: In this case series, we illustrate a possible approach to the use of cangrelor for patients undergoing TAVI and complex/high-risk PCI. In such complex cases, thorough pre-procedural planning might include a cangrelor to minimize vascular, bleeding, and ischaemic complications.
RESUMO
Background: Nordic walking (NW) has several potential benefits for individuals with cardiovascular (CV) disease, type 2 diabetes, and obesity and/or overweight. NW improves cardiovascular health, including exercise capacity and blood pressure control. NW enhances glycemic control and insulin sensitivity in diabetes, and aids in weight management and body composition improvement. NW offers additional advantages, such as improvement in muscular strength, joint mobility, physical activity levels, and psychological well-being. Methods: This open-label study with 3 arms will aim to evaluate the efficacy, safety, and adherence to exercise prescription in obese and/or overweight diabetic patients with CV complications. The primary objective will be to assess the CV performance of participants after a 6-month and a 12-month follow-up period, following a 3-month NW intervention, compared with standard rehabilitation, and with cardiological counseling (control group) training lasting 3 months. Results: The results of the study will provide valuable insights into the comparative effectiveness of a NW intervention vs standard rehabilitation and control group training in improving CV performance in obese and/or overweight diabetic patients with CV complications. Additionally, safety and adherence data will help inform the feasibility and sustainability of the exercise prescription over an extended period. Conclusions: These findings may have implications for the development of tailored exercise programs for this specific patient population, with the aim of optimizing CV health outcomes.

Contexte: La marche nordique offre plusieurs bienfaits potentiels aux personnes atteintes d'une maladie cardiovasculaire (CV), de diabète de type 2, de surpoids ou d'obésité. Elle améliore la santé cardiovasculaire, notamment l'endurance à l'effort et la régulation de la pression artérielle, en plus de favoriser l'équilibre glycémique et d'accroître la sensibilité à l'insuline chez les personnes diabétiques. Elle facilite également la gestion du poids et l'amélioration de la composition corporelle. Par ailleurs, la marche nordique présente d'autres avantages, comme l'augmentation de la force musculaire, de la mobilité articulaire, du niveau d'activité physique et du bien-être psychologique. Méthodologie: Cette étude ouverte à 3 groupes vise à évaluer l'efficacité, la sécurité et l'observance des exercices prescrits chez des sujets diabétiques obèses ou en surpoids présentant des complications CV. Le principal objectif consistera à évaluer la performance CV des participants au cours d'une période de suivi de 6 et 12 mois après un programme de marche nordique de 3 mois, comparativement à un programme de réadaptation standard et à un programme d'encadrement en soins CV (groupe témoin) de 3 mois. Résultats: Les résultats de l'étude fourniront de précieux renseignements sur l'efficacité d'un programme de marche rapide comparativement à un programme de réadaptation standard et à un programme d'encadrement (groupe témoin) pour améliorer la performance CV chez des sujets diabétiques obèses ou en surpoids présentant des complications CV. Les données relatives à la sécurité et à l'observance permettront également d'évaluer la faisabilité et la viabilité de la prescription d'exercices sur une longue période. Conclusions: Ces résultats pourraient s'avérer utiles dans l'élaboration de programmes d'exercices spécifiquement conçus pour cette population de patients, afin d'optimiser les résultats en santé CV.

RESUMO
Tricuspid insufficiency has long been considered an entity with low prognostic importance and associated with symptoms and signs only secondarily to left heart pathology. Scientific research in recent years has debunked this myth, demonstrating a key role in determining symptoms and signs of right heart failure, even in advanced stages. In parallel, advances in transcatheter technologies have opened up treatment options even for patients with increased surgical risk, who were previously excluded from traditional surgical options, with increasingly convincing results in reducing symptoms and improving the quality of life of our patients. The contemporary challenge is to translate these messages into everyday clinical practice and to encourage the centralization of patients in centers that currently have the expertise for feasibility evaluation and subsequent treatment. In this Review, we will analyze the most recent evidence on the pathophysiology and diagnosis of tricuspid insufficiency, the latest recommendations from European guidelines, and we will try to illustrate the most common technologies for percutaneous treatment and the abundant evidence supporting them.

AIMS: The optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in patients at high bleeding risk (HBR) is still debated. The current study, using the totality of existing evidence, evaluated the impact of an abbreviated DAPT regimen in HBR patients. METHODS AND RESULTS: A systematic review and meta-analysis was performed to search randomized clinical trials comparing abbreviated [i.e. very-short (1 month) or short (3 months)] with standard (≥6 months) DAPT in HBR patients without indication for oral anticoagulation. A total of 11 trials, including 9006 HBR patients, were included. Abbreviated DAPT reduced major or clinically relevant non-major bleeding [risk ratio (RR): 0.76, 95% confidence interval (CI): 0.61-0.94; I2 = 28%], major bleeding (RR: 0.80, 95% CI: 0.64-0.99, I2 = 0%), and cardiovascular mortality (RR: 0.79, 95% CI: 0.65-0.95, I2 = 0%) compared with standard DAPT. No difference in all-cause mortality, major adverse cardiovascular events, myocardial infarction, or stent thrombosis was observed. Results were consistent, irrespective of HBR definition and clinical presentation. CONCLUSION: In HBR patients undergoing PCI, a 1- or 3-month abbreviated DAPT regimen was associated with lower bleeding and cardiovascular mortality, without increasing ischaemic events, compared with a ≥6-month DAPT regimen.
