RESUMO
BACKGROUND: Limited data are available on the risk of periprocedural myocardial infarction (MI) in patients undergoing complex versus noncomplex percutaneous coronary intervention (PCI). METHODS: We assessed the risk of periprocedural MI according to the fourth Universal definition of myocardial infarction (UDMI) and several other criteria among patients undergoing elective PCI in a prospective, single-center registry. Complex PCI included at least one of the following: 3 coronary vessels treated, ≥3 stents implanted, ≥3 lesions treated, bifurcation with 2 stents implanted, total stent length >60 mm, treatment of chronic total occlusion, and use of rotational atherectomy. RESULTS: Between 2017 and 2021, we included 1010 patients with chronic coronary syndrome, of whom 226 underwent complex PCI (22.4%). The rate of periprocedural MI according to the fourth UDMI was significantly higher in complex compared to noncomplex PCI patients (26.5% vs. 14.5%, p < 0.001). Additionally, periprocedural MI was higher in the complex PCI group using SCAI (4% vs. 1.1%, p = 0.009), ARC-2 (13.7% vs. 8.0%, p = 0.013), ISCHEMIA (5.8% vs. 1.7%, p = 0.002), and EXCEL criteria (4.9% vs. 2.0%, p = 0.032). SYNTAX periprocedural MI occurred at low rates in both groups (0.9% vs. 0.6%, p = 0.657). Complex PCI was an independent predictor of the fourth UDMI periprocedural MI (odds ratio [OR] 1.54, 95% confidence interval [CI]: 1.04-2.27, p = 0.031). CONCLUSIONS: In patients with chronic coronary syndrome undergoing elective PCI, complex PCI is associated with a significantly higher risk of periprocedural MI using multiple definitions. These findings highlight the importance of considering upfront this risk in the planning of complex PCI procedures.

Heart failure (HF) has a global prevalence of 1-2%, and the incidence around the world is growing. The prevalence increases with age, from around 1% for those aged <55 years to >10% for those aged 70 years or over. Based on studies in hospitalized patients, about 50% of patients have heart failure with reduced ejection fraction (HFrEF), and 50% have heart failure with preserved ejection fraction (HFpEF). HF is associated with high morbidity and mortality, and HF-related hospitalizations are common, costly, and impact both quality of life and prognosis. More than 5-10% of patients deteriorate into advanced HF (AdHF) with worse outcomes, up to cardiogenic shock (CS) condition. Right heart catheterization (RHC) is essential to assess hemodynamics in the diagnosis and care of patients with HF. The aim of this article is to review the evidence on RHC in various clinical scenarios of patients with HF.
RESUMO
Background: There are limited data to assess pharmacodynamic (PD) profiles of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) and receiving cangrelor after pretreatment with ticagrelor. Methods: The PharmacOdynaMic effects of cangrelor in PatiEnts wIth acute or chronIc coronary syndrome undergoing percutaneous coronary intervention (POMPEII) registry (NCT04790032) is a prospective study conducted at Federico II University of Naples enrolling all patients undergoing PCI receiving cangrelor at operator's discretion. PD assessments were performed with 3 assays: (1) the gold standard light transmittance aggregometry (LTA) (20- and 5-µM adenosine diphosphate [ADP] stimuli); (2) VerifyNow P2Y12-test; (3) Multiplate electrode aggregometry (MEA), ADP-test. Results: We analyzed 13 STEMI patients pretreated with ticagrelor within 1 h at the time they underwent primary PCI receiving cangrelor. All patients showed low maximal platelet aggregation at 30-minute during cangrelor infusion, as well as at 3 h and 4-6 h (corresponding to 1 h and 2-4 h after stopping cangrelor infusion) with no cases of high residual platelet reactivity. These results were consistent with all assays. Conclusions: PD data show that in contemporary real-world STEMI patients pretreated within 1 h with ticagrelor undergoing primary PCI, adding cangrelor resulted in fast and potent platelet inhibition, thus suggesting that cangrelor may bridge the gap until ticagrelor reaches its effect.
RESUMO
Heart failure (HF) with preserved ejection fraction (HFpEF) is a prevalent global condition affecting approximately 50% of the HF population. With the aging of the worldwide population, its incidence and prevalence are expected to rise even further. Unfortunately, until recently, no effective medications were available to reduce the high mortality and hospitalization rates associated with HFpEF, making it a significant unmet need in cardiovascular medicine. Although HFpEF is commonly defined as HF with normal ejection fraction and elevated left ventricular filling pressure, performing invasive hemodynamic assessments on every individual suspected of having HFpEF is neither feasible nor practical. Consequently, several clinical criteria and diagnostic tools have been proposed to aid in diagnosing HFpEF. Overall, these criteria and tools are designed to assist healthcare professionals in identifying and evaluating patients who may have HFpEF based on a combination of signs, symptoms, biomarkers, and non-invasive imaging findings. By employing these non-invasive diagnostic approaches, clinicians can make informed decisions regarding the best pharmacological and rehabilitation strategies for individuals with suspected HFpEF. This literature review aims to provide an overview of all currently available methods for diagnosing and monitoring this disabling condition.

BACKGROUND: Periprocedural myocardial infarction (MI) according to the Society for Cardiovascular Angiography and Interventions (SCAI) criteria has prognostic relevance among patients undergoing percutaneous coronary intervention (PCI). However, it is unclear whether the type of cardiac biomarker used for the diagnosis of periprocedural MI plays a role in terms of event frequency and outcomes. OBJECTIVES: To compare the characteristics of SCAI periprocedural MI based on creatine kinase-myocardial band fraction (CK-MB) vs. high-sensitivity cardiac troponin (hs-cTn) in patients undergoing elective PCI. METHODS AND RESULTS: Between 2017 and 2021, periprocedural MI was assessed in a prospective study. The primary clinical outcome of interest was all-cause death at 1-year follow-up. A total of 1010 patients undergoing elective PCI were included. SCAI periprocedural MI based on CK-MB vs. hs-cTnI occurred in 1.8 and 13.5% of patients, respectively. hs-cTnI periprocedural MI in the absence of concomitant CK-MB criteria was associated with lower rates of ancillary criteria, including angiographic, ECG, and cardiac imaging criteria. At 1-year follow-up, periprocedural MI defined by CK-MB (adjusted hazard ratio, HR, 4.27, 95% confidence intervals, CI, 1.23-14.8; P = 0.022) but not hs-cTnI (adjusted HR 2.04, 95% CI 0.94-4.45; P = 0.072) was associated with a higher risk of all-cause death. Hs-cTnI periprocedural MI was not predictive of death unless accompanied by CK-MB criteria (adjusted HR 4.64, 95% CI 1.32-16.31; P = 0.017). CONCLUSION: In the setting of elective PCI, using hs-cTn instead of CK-MB resulted in a substantial increase in SCAI periprocedural MI events, which were not prognostically relevant in the absence of concurrent CK-MB elevations.

Multivessel disease is observed in approximately 50% of patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Data from randomized clinical trials has shown that complete revascularization in the STEMI setting improves clinical outcomes by reducing the risk of reinfarction and urgent revascularization. However, the timing and modality of revascularization of non-culprit lesions are still debated. PCI of non-culprit lesions can be performed during the index primary PCI or as a staged procedure and can be guided by angiography, functional assessment, or intracoronary imaging. In this review, we summarize the available evidence about the management of non-culprit lesions in STEMI patients with or without cardiogenic shock.
