RESUMO
Transcatheter aortic valve implantation may be complicated by the development of conduction disturbances, including left bundle branch block and high-grade atrioventricular blocks, especially in patients with predisposing risk factors, such as pre-existing right bundle branch block. Permanent pacemaker implantation is a procedure with potential short- and long-term complications, and it should be reserved to patients with appropriate indications. Electrophysiological testing and/or prolonged ambulatory ECG monitoring are valuable tools for stratifying the risk of pacemaker implantation. However, the management of new-onset conduction disorders is not always straightforward, and there are different approaches depending on the center's attitude. Therefore, the purpose of this review is to define clinical management based on current evidence, while awaiting data from randomized trials.

BACKGROUND: The FIRE trial (Functional Assessment in Elderly Myocardial Infarction Patients With Multivessel Disease) enrolled 1445 older (aged ≥75 years) patients with myocardial infarction and multivessel disease in Italy, Spain, and Poland. Patients were randomized to physiology-guided complete revascularization or treatment of the only culprit lesion. Physiology-guided complete revascularization significantly reduced ischemic adverse events at 1 year. This prespecified analysis investigated the changes between the 2 study groups in angina status, quality of life, physical performance, and frailty. METHODS: Patients underwent validated scales at hospital discharge (baseline) and 1 year later. Angina status was evaluated using the Seattle Angina Questionnaire, health-related quality of life by EQ visual analog scale, physical performance by short physical performance battery, and frailty by the clinical frailty scale. Mixed models for repeated measures analysis were used to study the association between the treatment arms, time, and scales. RESULTS: Baseline and 1-year Seattle Angina Questionnaire, EQ visual analog scale, short physical performance battery, and clinical frailty scale were collected in around two-thirds of the entire FIRE study population. The mean age was 80.9±4.6 years (female sex, 35.9%). Overall, 35.3% were admitted for ST-segment-elevation myocardial infarction, whereas the others were admitted for non-ST-segment-elevation myocardial infarction. Physiology-guided complete revascularization, compared with culprit-only revascularization, was associated with greater improvement in terms of angina status (Seattle Angina Questionnaire summary score, 7.3 [95% CI, 6.1-8.6] points), health-related quality of life (EQ visual analog scale, 6.2 [95% CI, 4.4-8.1] points), and physical performance (short physical performance battery, 1.1 [95% CI, 0.9-1.3] points). After 1 year, patients randomized to culprit-only revascularization experienced a deterioration in frailty status (clinical frailty scale, 0.2 [95% CI, 0.1-0.3] points), which was not observed in patients randomized to physiology-guided complete revascularization. CONCLUSIONS: The present analysis suggested that a physiology-guided complete revascularization is associated with consistent benefits in terms of angina status, quality of life, physical performance, and the absence of further deterioration of the frailty status.

Importance: Patients with high bleeding risk (HBR) have a poor prognosis, and it is not known if they may benefit from complete revascularization after myocardial infarction (MI). Objective: To investigate the benefit of physiology-guided complete revascularization vs a culprit-only strategy in patients with HBR, MI, and multivessel disease. Design, Setting, and Participants: This was a prespecified analysis of the Functional Assessment in Elderly MI Patients With Multivessel Disease (FIRE) randomized clinical trial data. FIRE was an investigator-initiated, open-label, multicenter trial. Patients 75 years or older with MI and multivessel disease were enrolled at 34 European centers from July 2019 through October 2021. Physiology treatment was performed either by angiography- or wire-based assessment. Patients were divided into HBR or non-HBR categories in accordance with the Academic Research Consortium HBR document. Interventions: Patients were randomized to either physiology-guided complete revascularization or culprit-only strategy. Main Outcomes and Measures: The primary outcome comprised a composite of death, MI, stroke, or revascularization at 1 year. Secondary outcomes included a composite of cardiovascular death or MI and Bleeding Academic Research Consortium (BARC) types 3 to 5. Results: Among 1445 patients (mean [SD] age, 81 [5] years; 917 male [63%]), 1025 (71%) met HBR criteria. Patients with HBR were at higher risk for the primary end point (hazard ratio [HR], 2.01; 95% CI, 1.47-2.76), cardiovascular death or MI (HR, 1.89; 95% CI, 1.26-2.83), and BARC types 3 to 5 (HR, 3.28; 95% CI, 1.40-7.64). The primary end point was significantly reduced with physiology-guided complete revascularization as compared with culprit-only strategy in patients with HBR (HR, 0.73; 95% CI, 0.55-0.96). No indication of interaction was noted between revascularization strategy and HBR status for primary and secondary end points. Conclusions and Relevance: HBR status is prevalent among older patients with MI, significantly increasing the likelihood of adverse events. Physiology-guided complete revascularization emerges as an effective strategy, in comparison with culprit-only revascularization, for mitigating ischemic adverse events, including cardiovascular death and MI.

BACKGROUND: The role of quantitative flow ratio (QFR) in the treatment of nonculprit vessels of patients with myocardial infarction (MI) is a topic of ongoing discussion. OBJECTIVES: This study aimed to investigate the predictive capability of QFR for adverse events and its noninferiority compared to wire-based functional assessment in nonculprit vessels of MI patients. METHODS: The FIRE (Functional Assessment in Elderly MI Patients With Multivessel Disease) trial randomized 1,445 older MI patients to culprit-only (n = 725) or physiology-guided complete revascularization (n = 720). In the culprit-only arm, angiographic projections of nonculprit vessels were prospectively collected, centrally reviewed for QFR computation, and associated with endpoints. In the complete revascularization arm, endpoints were compared between nonculprit vessels investigated with QFR or wire-based functional assessment. The primary endpoint was the vessel-oriented composite endpoint (VOCE) at 1 year. RESULTS: QFR was measured on 903 nonculprit vessels from 685 patients in the culprit-only arm. Overall, 366 (40.5%) nonculprit vessels showed a QFR value ≤0.80, with a significantly higher incidence of VOCEs (22.1% vs 7.1%; P < 0.001). QFR ≤0.80 emerged as an independent predictor of VOCEs (HR: 2.79; 95% CI: 1.64-4.75). In the complete arm, QFR was used in 320 (35.2%) nonculprit vessels to guide revascularization. When compared with propensity-matched nonculprit vessels in which treatment was guided by wire-based functional assessment, no significant difference was observed (HR: 0.57; 95% CI: 0.28-1.15) in VOCEs. CONCLUSIONS: This prespecified subanalysis of the FIRE trial provides evidence supporting the safety and efficacy of QFR-guided interventions for the treatment of nonculprit vessels in MI patients.

BACKGROUND: Use of Intra-Aortic Balloon Pump (IABP) in combination with Impella has been described as an alternative strategy for mechanical circulatory support (MCS) in patients with cardiogenic shock (CS). We provide a systematic review aimed to explore the effectiveness of this paired MCS approach. METHODS: We conducted a comprehensive systematic search in MEDLINE, Scopus, and Cochrane databases to identify all studies that investigated dual MCS with IABP and Impella. RESULTS: Our search strategy identified 12 articles, including 1 randomized controlled trial, 1 retrospective study, 1 case series, 7 case report and 2 animal studies. Rationale for this combined MCS strategy stems from an observed reduction in myocardial oxygen demand/supply ratio compared to the use of each device alone, without determining significant variations in left ventricular work. Nonetheless, this combined approach also leads to a 30-40 % decline in Impella flow, increasing the risk of bleeding, Impella displacement, as well as triggering positioning and pressure alarms. Additionally, hemolytic risk data yielded inconclusive results. Importantly, there were no notable disparities in mortality rates when comparing the combined strategy to the use of each device individually. CONCLUSION: At the current state-of-the-art, there are no conclusive data demonstrating net clinical benefits of combining Impella with IABP. Considering the substantial risks of morbidity associated, we recommend against its use in clinical practice.
RESUMO
We aimed to develop and validate a COVID-19 specific scoring system, also including some ECG features, to predict all-cause in-hospital mortality at admission. Patients were retrieved from the ELCOVID study (ClinicalTrials.gov identifier: NCT04367129), a prospective, multicenter Italian study enrolling COVID-19 patients between May to September 2020. For the model validation, we randomly selected two-thirds of participants to create a derivation dataset and we used the remaining one-third of participants as the validation set. Over the study period, 1014 hospitalized COVID-19 patients (mean age 74 years, 61% males) met the inclusion criteria and were included in this analysis. During a median follow-up of 12 (IQR 7-22) days, 359 (35%) patients died. Age (HR 2.25 [95%CI 1.72-2.94], p < 0.001), delirium (HR 2.03 [2.14-3.61], p = 0.012), platelets (HR 0.91 [0.83-0.98], p = 0.018), D-dimer level (HR 1.18 [1.01-1.31], p = 0.002), signs of right ventricular strain (RVS) (HR 1.47 [1.02-2.13], p = 0.039) and ECG signs of previous myocardial necrosis (HR 2.28 [1.23-4.21], p = 0.009) were independently associated to in-hospital all-cause mortality. The derived risk-scoring system, namely EL COVID score, showed a moderate discriminatory capacity and good calibration. A cut-off score of ≥ 4 had a sensitivity of 78.4% and 65.2% specificity in predicting all-cause in-hospital mortality. ELCOVID score represents a valid, reliable, sensitive, and inexpensive scoring system that can be used for the prognostication of COVID-19 patients at admission and may allow the earlier identification of patients having a higher mortality risk who may be benefit from more aggressive treatments and closer monitoring.
RESUMO
AIMS: The present analysis from the Functional Assessment in Elderly Myocardial Infarction Patients with Multivessel Disease (FIRE) trial aims to explore the significance of pre-admission physical activity and assess whether the benefits of physiology-guided complete revascularization apply consistently to sedentary and active older patients. METHODS AND RESULTS: Patients aged 75 years or more with myocardial infarction (MI) and multivessel disease were randomized to receive physiology-guided complete revascularization or culprit-only strategy. The primary outcome was a composite of death, MI, stroke, or any revascularization within a year. Secondary endpoints included the composite of cardiovascular death or MI, as well as single components of the primary endpoint. Pre-admission physical activity was categorized into three groups: (i) absent (sedentary), (ii) light, and (iii) vigorous. Among 1445 patients, 692 (48%) were sedentary, whereas 560 (39%) and 193 (13%) performed light and vigorous physical activity, respectively. Patients engaging in light or vigorous pre-admission physical activity exhibited a reduced risk of the primary outcome compared with sedentary individuals [light hazard ratio (HR) 0.70, 95% confidence interval (CI) 0.55-0.91 and vigorous HR 0.14, 95% CI 0.07-0.91, respectively]. These trends were also observed for death, cardiovascular death, or MI. When comparing physiology-guided complete revascularization vs. culprit-only strategy, no significant interaction was observed for primary and secondary endpoints when stratified by sedentary or active status. CONCLUSION: In older patients with MI, pre-admission physical activity emerges as a robust and independent prognostic determinant. Physiology-guided complete revascularization stands out an effective strategy in reducing ischaemic adverse events, irrespective of pre-admission physical activity status. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT03772743.
The Functional Assessment in Elderly Myocardial Infarction Patients with Multivessel Disease (FIRE) trial has shown that physiology-guided complete revascularization reduces ischaemic adverse events in older patients with myocardial infarction (MI) and multivessel disease. Older patients who engage in light or vigorous physical activity before hospitalization for MI have a reduced risk of the primary composite outcome of death, MI, stroke, or ischaemia-driven revascularization. These benefits extend to all secondary cardiovascular outcomes as well. In the present subanalysis of the FIRE trial, we find that the positive prognosis associated with physiology-guided complete revascularization holds true even for patients with a sedentary lifestyle. This means that this type of revascularization can effectively reduce ischaemic adverse events in older patients with MI and multivessel disease, regardless of their physical activity levels.
RESUMO
Background: Balloon aortic valvuloplasty (BAV) is a palliative tool for patients with symptomatic severe aortic stenosis (AS) at prohibitive risk for surgery or as a bridge to surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). BAV is traditionally performed in hospitals with onsite cardiac surgery due to its potential complications. Aims: The aim of this study was to evaluate the safety of BAV procedures performed by trained high-volume operators in a centre without onsite surgery and to assess the effect of a minimalistic approach to reduce periprocedural complications. Methods: From 2016 to 2021, 187 BAV procedures were performed in 174 patients. Patients were elderly (mean age: 85.0±5.4 years) and had high-risk (mean European System for Cardiac Operative Risk Evaluation score [EuroSCORE] II: 10.1±9.9) features. According to the indications, 4 cohorts were identified: 1) bridge to TAVR (n=98; 56%); 2) bridge to SAVR (n=8; 5%); 3) cardiogenic shock (n=11; 6%); and 4) palliation (n=57; 33%). BAV procedures were performed using the standard retrograde technique via femoral access in 165 patients (95%), although radial access was used in 9 patients (5%). Ultrasound-guided vascular puncture was performed in 118 patients (72%) and left ventricular pacing was administered through a stiff guidewire in 105 cases (60%). Results: BAV safety was confirmed by 1 periprocedural death (0.6%), 1 intraprocedural stroke (0.6%), 2 major vascular complications (1%) and 9 minor vascular complications (5%). Nine cases of in-hospital mortality occurred (5%), predominantly in patients with cardiogenic shock. Conclusions: BAV is a safe procedure that can be performed in centres without onsite cardiac surgery using a minimalistic approach that can reduce periprocedural complications.
RESUMO
INTRODUCTION: The cardiovascular (CV) safety of testosterone (T) replacement therapy (TRT) is still conflicting. Recent data suggested a TRT-related increased risk of atrial fibrillation (AF). The aim of this study was to systematic review and meta-analyze CV risk related to TRT as derived from placebo controlled randomized trials (RCTs). AREAS COVERED: An extensive Medline, Embase, and Cochrane search was performed. All placebo-controlled RCTs reporting data on TRT-related CV safety were considered. To better analyze the role of T on AF, population-based studies investigating the relationship between endogenous circulating T levels and AF incidence were also included and analyzed. EXPERT OPINION: Out of 3.615, 106 studies were considered, including 8.126 subjects treated with TRT and 7.310 patients allocated to placebo. No difference between TRT and placebo was observed when major adverse CV events were considered. Whereas the incidence of non-fatal arrhythmias and AF was increased in the only trial considering CV safety as the primary endpoint, this was not confirmed when all other studies were considered (MH-OR 1.61[0.84;3.08] and 1.44[0.46;4.46]). Similarly, no relationship between endogenous T levels and AF incidence was observed after the adjustment for confounders Available data confirm that TRT is safe and it is not related to an increased CV risk.

INTRODUCTION: The potential benefit on long term outcomes of Percutaneous Coronary Intervention (PCI) on Unprotected Left Main (ULM) driven by IntraVascular UltraSound (IVUS) remains to be defined. METHODS: IMPACTUS LM-PCI is an observational, multicenter study that enrolled consecutive patients with ULM disease undergoing coronary angioplasty in 13 European high-volume centers from January 2002 to December 2015. Major Adverse Cardiovascular Events (MACEs) a composite of cardiovascular (CV) death, target vessel revascularization (TVR) and myocardial infarction (MI) were the primary endpoints, while its single components along with all cause death the secondary ones. RESULTS: 627 patients with ULM disease were enrolled, 213 patients (34%) underwent IVUS-guided PCI while 414 (66%) angioguided PCI. Patients in the two cohorts had similar prevalence of risk factors except for active smoking and clinical presentation. During a median follow-up of 7.5 years, 47 (22%) patients in the IVUS group and 211 (51%) in the angio-guided group underwent the primary endpoint (HR 0.42; 95% CI [0.31-0.58] p < 0.001). After multivariate adjustment, IVUS was significantly associated with a reduced incidence of the primary endpoint (adj HR 0.39; 95% CI [0.23-0.64], p < 0.001), mainly driven by a reduction of TVR (ad HR 0.30, 95% CI [0.15-0.62], p = 0.001) and of all-cause death (adj HR 0.47, 95% CI [0.28-0.82], p = 0.008). IVUS use, age, diabetes, side branch stenosis, DES and creatinine at admission were independent predictors of MACE. CONCLUSIONS: In patients undergoing ULM PCI, the use of IVUS was associated with a reduced risk at long-term follow-up of MACE, all-cause death and subsequent revascularization.

BACKGROUND: Cardiac magnetic resonance (CMR) plays a pivotal diagnostic role in myocardial infarction with nonobstructive coronary arteries (MINOCA). To date, a prognostic stratification of these patients is still lacking. OBJECTIVES: This study aims to assess the prognostic role of CMR in MINOCA. METHODS: The authors assessed 437 MINOCA from January 2017 to October 2021. They excluded acute myocarditis, takotsubo syndromes, cardiomyopathies, and other nonischemic etiologies. Patients were classified into 3 subgroups according to the CMR phenotype: 1) presence of late gadolinium enhancement (LGE) and abnormal mapping (M) values (LGE+/M+); 2) regional ischemic injury with abnormal mapping and no LGE (LGE-/M+); and 3) nonpathological CMRs (LGE-/M-). The primary outcome was the presence of major adverse cardiovascular events (MACE). The mean follow-up was 33.7 ± 12.0 months and CMR was performed on average at 4.8 ± 1.5 days from the acute presentation. RESULTS: The final cohort included 198 MINOCA; 116 (58.6%) comprised the LGE+/M+ group. During follow-up, MACE occurred significantly more frequently in MINOCA LGE+/M+ than in the LGE+/M- and normal-CMR (LGE-/M-) subgroups (20.7% vs 6.7% and 2.7%; P = 0.006). The extension of myocardial damage at CMR was significantly greater in patients who developed MACE. In multivariable Cox regression, %LGE was an independent predictor of MACE (HR: 1.123 [95% CI: 1.064-1.185]; P < 0.001) together with T2 mapping values (HR: 1.190 [95% CI: 1.145-1.237]; P = 0.001). CONCLUSIONS: In MINOCA with early CMR execution, the %LGE and abnormal T2 mapping values were identified as independent predictors of adverse cardiac events at â¼3.0 years of follow-up. These parameters can be considered as high-risk markers in MINOCA.

Femoral access site-related bleeding represent a prognostically impactful issue in interventional cardiology. The impact of a combined use of ultrasound guidance for femoral access and vascular closure device deployment for arteriotomy closure in femoral artery procedures on bleeding complications is still largely unknown. A systematic review was conducted on Pubmed (Medline), Cochrane library and Biomed Central databases between March and April 2023. A total of 9 studies have been selected, of namely 4 registries, 4 prospective studies and one randomized clinical trial. A systematic use of US guidance to access femoral artery resulted feasible and not time consuming, reduced venipuncture and increased first attempt success. Combination of US guidance and deployment of VCD's had the capacity to further decrease vascular and bleeding combination, especially in those patients at a higher risk of post-procedural bleeding. Ultrasound can be easily used during closure device deployment to reduce device failure and major vascular complications.

BACKGROUND: Beta blockers (BBs) are a cornerstone for patients with heart failure (HF) and ventricular dysfunction. However, their use in patients recovering from a cardiogenic shock (CS) remains a bone of contention, especially regarding whether and when to reintroduce this class of drugs. METHODS: FRENSHOCK is a prospective multicenter registry including 772 CS patients from 49 centers. Our aim was to compare outcomes (1-month and 1-year all-cause mortality) between CS patients taking and those not taking BBs in three scenarios: (1) at 24 h after CS; (2) patients who did or did not discontinue BBs within 24 h; and (3) patients who did or did not undergo the early introduction of BBs. RESULTS: Among the 693 CS included, at 24 h after the CS event, 95 patients (13.7%) were taking BB, while 598 (86.3%) were not. Between the groups, there were no differences in terms of major comorbidities or initial CS triggers. Patients receiving BBs at 24 h presented a trend toward reduced all-cause mortality both at 1 month (aHR = 0.61, 95% CI 0.34 to 1.1, p = 0.10) and 1 year, which was, in both cases, not significant. Compared with patients who discontinued BBs at 24 h, patients who did not discontinue BBs showed lower 1-month mortality (aHR = 0.43, 95% CI 0.2 to 0.92, p = 0.03) and a trend to lower 1-year mortality. No reduction in outcomes was observed in patients who underwent an early introduction of BB therapy. CONCLUSIONS: BBs are drugs of first choice in patients with HF and should also be considered early in patients with CS. In contrast, the discontinuation of BB therapy resulted in increased 1-month all-cause mortality and a trend toward increased 1-year all-cause mortality.
RESUMO
Background: the prognosis of patients with myocardial infarction with non-obstructive coronary arteries (MINOCA) is not benign; thus, prompting the need to validate prognostic scoring systems for this population. Aim: to evaluate and compare the prognostic performance of GRACE, TIMI, HEART, and ACEF scores in MINOCA patients. Methods: A total of 250 MINOCA patients from January 2017 to September 2021 were included. For each patient, the four scores at admission were retrospectively calculated. The primary outcome was a composite of all-cause death and acute myocardial infarction (AMI) at 1-year follow-up. The ability to predict 1-year all-cause death was also tested. Results: Overall, the tested scores presented a sub-optimal performance in predicting the composite major adverse event in MINOCA patients, showing an AUC ranging between 0.7 and 0.8. Among them, the GRACE score appeared to be the best in predicting all-cause death, reaching high specificity with low sensitivity. The best cut-off identified for the GRACE score was 171, higher compared to the cut-off of 140 generally applied to identify high-risk patients with obstructive AMI. When the scores were tested for prediction of 1-year all-cause death, the GRACE and the ACEF score showed very good accuracy (AUC = 0.932 and 0.828, respectively). Conclusion: the prognostic scoring tools, validated in AMI cohorts, could be useful even in MINOCA patients, although their performance appeared sub-optimal, prompting the need for risk assessment tools specific to MINOCA patients.
RESUMO
BACKGROUND: The benefit of complete revascularization in older patients (≥75 years of age) with myocardial infarction and multivessel disease remains unclear. METHODS: In this multicenter, randomized trial, we assigned older patients with myocardial infarction and multivessel disease who were undergoing percutaneous coronary intervention (PCI) of the culprit lesion to receive either physiology-guided complete revascularization of nonculprit lesions or to receive no further revascularization. Functionally significant nonculprit lesions were identified either by pressure wire or angiography. The primary outcome was a composite of death, myocardial infarction, stroke, or any revascularization at 1 year. The key secondary outcome was a composite of cardiovascular death or myocardial infarction. Safety was assessed as a composite of contrast-associated acute kidney injury, stroke, or bleeding. RESULTS: A total of 1445 patients underwent randomization (720 to receive complete revascularization and 725 to receive culprit-only revascularization). The median age of the patients was 80 years (interquartile range, 77 to 84); 528 patients (36.5%) were women, and 509 (35.2%) were admitted for ST-segment elevation myocardial infarction. A primary-outcome event occurred in 113 patients (15.7%) in the complete-revascularization group and in 152 patients (21.0%) in the culprit-only group (hazard ratio, 0.73; 95% confidence interval [CI], 0.57 to 0.93; P = 0.01). Cardiovascular death or myocardial infarction occurred in 64 patients (8.9%) in the complete-revascularization group and in 98 patients (13.5%) in the culprit-only group (hazard ratio, 0.64; 95% CI, 0.47 to 0.88). The safety outcome did not appear to differ between the groups (22.5% vs. 20.4%; P = 0.37). CONCLUSIONS: Among patients who were 75 years of age or older with myocardial infarction and multivessel disease, those who underwent physiology-guided complete revascularization had a lower risk of a composite of death, myocardial infarction, stroke, or ischemia-driven revascularization at 1 year than those who received culprit-lesion-only PCI.

The wearable cardioverter defibrillator (WCD) has been proven to be effective in preventing sudden cardiac death (SCD) in patients soon after acute myocardial infarction (AMI) and left ventricular ejection fraction (LVEF) ≤35%. The aim of this study was to assess whether a WCD may shorten the length of an initial hospital stay (total length, days in the intensive care unit (ICU) and in the acute cardiac care unit (ACCU)) among these patients. This was a single-centre, retrospective observational study of patients referred for the management of SCD risk post-AMI and LVEF ≤35%, in a tertiary care hospital. The clinical characteristics and length of index hospitalization of the group of patients discharged, with or without WCD, were compared. A propensity score analysis was performed, then weighted regression models were conducted. A total of 101 patients in the WCD group and 29 in the control group were enrolled in the analysis. In the weighted regression models, WCD significantly reduced the days spent in ACCU (p < 0.001). WCD patients had significantly fewer days spent in ACCU (5.5 ± 2.6 vs. 8.4 ± 12.8 days, p < 0.001) and shorter hospitalizations (10.2 ± 5.7 vs. 13.4 ± 17.6 days, p = 0.005), compared with the control group. It was concluded that the WCD appears to reduce the total length of hospitalization and lengths of stay in ACCU for patients post-AMI and with left ventricular dysfunction.
RESUMO
AIMS: The aim of the study is to evaluate the impact of sex on acute myocardial infarction (AMI) patients' clinical presentation and outcomes, comparing those with non-obstructive and obstructive coronary arteries (MINOCA vs. MIOCA). METHODS AND RESULTS: We enrolled 2455 patients with AMI undergoing coronary angiography from January 2017 to September 2021. Patients were divided according to the type of AMI and sex: male (n = 1593) and female (n = 607) in MIOCA and male (n = 87) and female (n = 168) in MINOCA. Each cohort was further stratified based on age (≤/> 70 years). The primary endpoint (MAE) was a composite of all-cause death, recurrent AMI, and hospitalization for heart failure (HF) at follow-up. Secondary outcomes included all-cause and cardiovascular death, recurrent AMI, HF re-hospitalization, and stroke. MINOCA patients were more likely to be females compared with MIOCA ones (P < 0.001). The median follow-up was 28 (15-41) months. The unadjusted incidence of MAE was significantly higher in females compared with males, both in MINOCA [45 (26.8%) vs. 12 (13.8%); P = 0.018] and MIOCA cohorts [203 (33.4%) vs. 428 (26.9%); P = 0.002]. Age was an independent predictor of MAE in both cohorts. Among MINOCA patients, females ≤70 years old had a higher incidence of MAE [18 (23.7%) vs. 4 (5.9%); P = 0.003] compared with male peers, mainly driven by a higher rate of re-hospitalization for HF (P = 0.045) and recurrence of AMI (P = 0.006). Only in this sub-group of MINOCA patients, female sex was an independent predictor of MAE (hazard ratio = 3.09; 95% confidence interval: 1.02-9.59; P = 0.040). MINOCA females ≤70 years old had worse outcomes than MIOCA female peers. CONCLUSION: MINOCA females ≤70 years old had a significantly higher incidence of MAE, compared with males and MIOCA female peers, likely due to the different pathophysiology of the ischaemic event. TRIAL REGISTRATION: Data were part of the ongoing observational study 'AMIPE: Acute Myocardial Infarction, Prognostic and Therapeutic Evaluation' (ClinicalTrials.gov Identifier: NCT03883711).

AIMS: To analyze the association between chronic SGLT2-I treatment and development of contrast-induced acute kidney injury (CI-AKI) in diabetic patients with acute myocardial infarction (AMI) undergoing PCI. METHODS: Multicenter international registry of consecutive patients with type 2 diabetes mellitus (T2DM) and AMI undergoing PCI between 2018 and 2021. The study population was stratified by the presence of chronic kidney disease (CKD) and anti-diabetic therapy at admission (SGLT2-I versus non-SGLT2-I users). RESULTS: The study population consisted of 646 patients: 111 SGLT2-I users [28 (25.2%) with CKD] and 535 non-SGLT2-I users [221 (41.3%) with CKD]. The median age was 70 [61-79] years. SGLT2-I users exhibited significantly lower creatinine values at 72 h after PCI, both in the non-CKD and CKD stratum. The overall rate of CI-AKI was 76 (11.8%), significantly lower in SGLT2-I users compared to non-SGLT2-I patients (5.4% vs 13.1%, p = 0.022). This finding was also confirmed in patients without CKD (p = 0.040). In the CKD cohort, SGLT2-I users maintained significantly lower creatinine values at discharge. The use of SGLT2-I was an independent predictor of reduced rate of CI-AKI (OR 0.356; 95%CI 0.134-0.943, p = 0.038). CONCLUSION: In T2DM patients with AMI, the use of SGLT2-I was associated with a lower risk of CI-AKI, mostly in patients without CKD.

Coronary artery disease is the predominant aetiology of heart failure and left ventricular dysfunction in industrialized countries. The pathophysiological substrate of hibernating myocardium constitutes the conceptual target of coronary revascularization by coronary artery bypass graft (CABG) or coronary angioplasty or percutaneous coronary intervention (PCI). Studies, mainly observational, conducted in the past have demonstrated a prognostic benefit of CABG on survival. These findings were confirmed by the long-term follow-up of the STICH study in which, however, documentation of inducible ischaemia or myocardial viability was not predictive of a prognostic benefit of CABG. Revascularization via PCI in the recent REVIVED-BCIS2 study did not demonstrate a significant benefit in terms of death or heart failure hospitalization compared with optimal medical therapy. Pending the long-term follow-up of the REVIVED-BCIS2 study, optimized medical therapy, cardiac resynchronization therapy, and the implantable cardioverter defibrillator, where indicated, are the mainstay of treatment in patients with dilated ischaemic cardiomyopathy. The decision for coronary revascularization is made in the individual patient, possibly with a higher bias in patients with angina, three-vessel coronary artery disease, severe left ventricular dysfunction, and cardiac remodelling.
