    Abstract: Deferring revascularization in patients with nonsignificant stenoses based on fractional flow reserve (FFR) is associated with favorable clinical outcomes up to 15 years. Whether this holds true in patients with reduced left ventricular ejection fraction is unclear. We aimed to investigate whether FFR provides adjunctive clinical benefit compared with coronary angiography in deferring revascularization of patients with intermediate coronary stenoses and reduced left ventricular ejection fraction. Methods and Results Consecutive patients with reduced left ventricular ejection fraction (≤50%) undergoing coronary angiography between 2002 and 2010 were screened. We included patients with at least 1 intermediate coronary stenosis (diameter stenosis ≥40%) in whom revascularization was deferred based either on angiography plus FFR (FFR guided) or angiography alone (angiography guided). The primary end point was the cumulative incidence of all‐cause death at 10 years. The secondary end point (incidence of major adverse cardiovascular and cerebrovascular events) was a composite of all‐cause death, myocardial infarction, any revascularization, and stroke. A total of 840 patients were included (206 in the FFR‐guided group and 634 in the angiography‐guided group). Median follow‐up was 7 years (interquartile range, 3.22–11.08 years). After 1:1 propensity‐score matching, baseline characteristics between the 2 groups were similar. All‐cause death was significantly lower in the FFR‐guided group compared with the angiography‐guided group (94 [45.6%] versus 119 [57.8%] ; hazard ratio [HR], 0.65 [95% CI, 0.49–0.85] ; P 〈 0.01). The rate of major adverse cardiovascular and cerebrovascular events was lower in the FFR‐guided group (123 [59.7%] versus 139 [67.5%] ; HR, 0.75 [95% CI, 0.59–0.95]; P =0.02). Conclusions In patients with reduced left ventricular ejection fraction, deferring revascularization of intermediate coronary stenoses based on FFR is associated with a lower incidence of death and major adverse cardiovascular and cerebrovascular events at 10 years.

    Abstract: Non‐invasive myocardial work (MW) is a validated index of left ventricular (LV) systolic performance, incorporating afterload and myocardial metabolism. The role of MW in predicting the first hospitalization for de novo heart failure with preserved ejection fraction (HFpEF) is still unknown. We aim to investigate the diagnostic performance of MW to predict the first de novo HFpEF hospitalization in ambulatory individuals with preserved LV ejection fraction. Methods and results Twenty‐nine patients with transthoracic echocardiography performed at least 6 months before the first HFpEF hospitalization were compared with 29 matched controls. MW was derived as the area of pressure–strain loop using speckle‐tracking and brachial artery blood pressure. Global work index, global constructive work, global wasted work (GWW), and global work efficiency (GWE) were collected. First HFpEF hospitalization and its combination with cardiovascular death [major adverse cardiovascular events (MACE)] and all‐cause of death [major adverse events (MAE)] were assessed. At baseline, future HFpEF patients showed lower global work index, global constructive work, GWE, and higher GWW than controls (all P   〈  0.05). At admission vs. baseline, GWE significantly decreased, and GWW increased in the HFpEF group ( P   〈  0.05), whereas no significant difference was observed in the controls over time. GWW, with a cut‐off of 170 mmHg%, showed the largest area under the curve (AUC) to predict first HFpEF hospitalization [AUC = 0.80, 95% confidence interval (CI) 0.69–0.91, P   〈  0.001], MACE (AUC = 0.80, 95% CI 0.66–0.90, P   〈  0.001), and MAE (AUC = 0.79, 95% CI 0.62–0.88, P  = 0.001). GWW  〉  170 mmHg% was associated with a 4‐fold increase of MACE (HR = 4.5, 95% CI 1.59–13.12, P  = 0.005) and a 3‐fold higher risk of MAE (HR = 2.9, 95% CI 1.24–6.6, P  = 0.014). Conclusions In ambulatory patients with preserved LV ejection fraction and risk factors, GWW showed high accuracy to predict the first HFpEF hospitalization and its combination with mortality. The GWW routine assessment may be clinically helpful in patients with dyspnoea.

    Abstract: Sodium-glucose co-transporter 2 inhibitors (SGLT2-i) have shown significant cardiovascular benefits in patients with and without type 2 diabetes mellitus (T2DM). They have also gained interest for their potential anti-arrhythmic role and their ability to reduce the occurrence of atrial fibrillation (AF) and ventricular arrhythmias (VAs) in T2DM and heart failure patients. Objectives To investigate in-hospital new-onset cardiac arrhythmias in a cohort of T2DM patients presenting with acute myocardial infarction (AMI) treated with SGLT2-i vs. other oral anti-diabetic agents (non-SGLT2-i users). Methods Patients from the SGLT2-I AMI PROTECT registry (NCT05261867) were stratified according to the use of SGLT2-i before admission for AMI, divided into SGLT2-i users vs. non-SGLT2-i users. In-hospital outcomes included the occurrence of in-hospital new-onset cardiac arrhythmias (NOCAs), defined as a composite of new-onset AF and sustained new-onset ventricular tachycardia (VT) and/or ventricular fibrillation (VF) during hospitalization. Results The study population comprised 646 AMI patients categorized into SGLT2-i users (111 patients) and non-SGLT2-i users (535 patients). SGLT2-i users had a lower rate of NOCAs compared with non-SGLT2-i users (6.3 vs. 15.7%, p = 0.010). Moreover, SGLT2-i was associated with a lower rate of AF and VT/VF considered individually ( p = 0.032). In the multivariate logistic regression model, after adjusting for all confounding factors, the use of SGLT2-i was identified as an independent predictor of the lower occurrence of NOCAs (OR = 0.35; 95%CI 0.14–0.86; p = 0.022). At multinomial logistic regression, after adjusting for potential confounders, SGLT2-i therapy remained an independent predictor of VT/VF occurrence (OR = 0.20; 95%CI 0.04–0.97; p = 0.046) but not of AF occurrence. Conclusions In T2DM patients, the use of SGLT2-i was associated with a lower risk of new-onset arrhythmic events during hospitalization for AMI. In particular, the primary effect was expressed in the reduction of VAs. These findings emphasize the cardioprotective effects of SGLT2-i in the setting of AMI beyond glycemic control. Trial registration Data are part of the observational international registry: SGLT2-I AMI PROTECT. ClinicalTrials.gov , identifier: NCT05261867.

    Abstract: Percutaneous coronary interventions (PCI) in calcified coronary artery lesions are associated with impaired stent expansion, higher rate of periprocedural complications and cardiac mortality. Lesion preparation using calcium modifying techniques such as Rotational Atherectomy (RA) or Intravascular Lithotripsy (IVL) has been advocated. Studies comparing these technologies are lacking. We aimed to compare the in-stent pressure gradient, evaluated by virtual fractional flow-reserve, in calcific lesions treated using either RA or IVL. Methods and results Patients undergoing either RA- or IVL-assisted PCI from two European centres were included. Propensity score matching (1:2) was performed to control for potential bias. Primary outcome was post-PCI in-stent pressure gradient calculated by virtual fractional flow reserve (vFFRgrad). Secondary outcomes included the proportion of patients with complete functional revascularization defined as of distal vFFR post PCI (vFFRpost) ≥0.90. From a cohort of 210 patients, 105 matched patients (70 RA and 35 IVL) were included. Pre-PCI vFFR did not differ between groups (0.65 ± 0.13 RA and 0.67 ± 0.11 IVL). After PCI, in-stent pressure gradients was significantly lower in the IVL group (0.032 ± 0.026 vs. 0.043 ± 0.026 in the RA group, P = 0.024). The proportion of vessels with functional complete revascularization was similar between the two groups (32.9% vs. 37.1% in the RA and IVL group, respectively; P = 0.669). Conclusions Calcific lesions preparation with IVL is effective and resulted in improved in-stent pressure gradient compared to RA. Approximately one third of the patients undergoing PCI for a severely calcified lesion achieved functional revascularization with no difference between rotational RA and IVL. 662 FigureIn stent gradients after RA and IVL.

    Abstract: Percutaneous coronary interventions (PCI) in calcified coronary artery lesions is associated with higher rate of cardiovascular adverse events and mortality. The aim of our study was to evaluate the prognostic impact of High Bleeding Risk (HBR) condition, as defined by the Academic Research Consortium (ARC) HBR criteria, on clinical outcomes in patients with complex calcified coronary artery disease undergoing PCI after lesion preparation using Rotational Atherectomy (RA). Methods In this observational retrospective study, all patients with calcified coronary artery disease undergoing RA-assisted PCI between 2011 and 2021 were included. According to ARC-HBR criteria, patients were considered at HBR if at least one major criterion or two minor criteria were met. The primary endpoint was the occurrence of major adverse cardiac and cerebrovascular events (MACCE) at 4 years defined as the composite of cardiovascular death, myocardial infarction, stroke and target vessel revascularization (TVR). Secondary endpoints were cardiovascular death, bleeding events and TVR. Results The final population consisted of 343 patients. Median follow-up was 39 months. Among patients, 198 (57,7%) met the HBR criteria while 145 (42,7%) did not. Patients with HBR criteria were older [78.21 vs 71.68; p & lt; 0.001], with lower GFR (ml/min/1.73m2) [53.67 vs 77.51; p & lt; 0.001] and lower hemoglobin levels [Hb: g/dl; 11.93 vs 13.74; p & lt; 0.001] compare with patients without HBR. The rate of MACCE was significantly higher in patients at HBR compare with patients not at HBR (HR 1.86 [1.08-3.26] ; p = 0.026) mainly driven by an increased risk of cardiovascular death. No significant differences were found concerning the rates of TVR (HR 0.48 [0.21-1.04]; p = 0.057), stroke (HR=7.7 [0.98-61.09] , p=0.05) and MI (HR 2.2[0.58-8.35], p=0.241) between the two groups. Bleedings were more frequent in patients at HBR (HR 12.31 [2.93-51.64] ; p & lt; 0.001) compared to patients without HBR. Conclusion In patients with calcified coronary artery disease PCI, despite the use of dedicated tools for optimal lesion preparation such as RA, those at HBR still present higher risk of MACCE and cardiovascular death. Conversely, rates of TVR and MI were comparable, suggesting frailty and comorbidities as primary causes of worse outcomes in patients at HBR. Figure Legend: Panel A: the rate of MACCE was significantly higher in patients at HBR compare with patients not at HBR (HR 1.86 [1.08-3.26]; p = 0.026),) mainly driven by an increased risk of cardiovascular death (Panel B). Panel C: the rates of TVR were not significant different between the two groups (HR 0.48 [0.21-1.04]; p = 0.057). Panel D: Bleedings were more frequent in patients at HBR (HR 12.31 [2.93-51.64]; p & lt; 0.001) compared to patients without HBR.

    Abstract: Sodium-glucose co-transporter 2 inhibitors (SGLT2-I) currently receive intense clinical interest in patients with and without diabetes mellitus (DM) with pleiotropic beneficial effects. Nowadays, the inflammation response in the setting of acute myocardial infarction (AMI) has been proposed as a potential pharmacological intervention target. In this setting, we tested the hypothesis that the SGLT2-I displays anti-inflammatory effect along with glucose-lowering properties. We investigated the relationship between stress hyperglycemia, inflammation burden and infarct size in a cohort of type 2 diabetic AMI patients treated with SGLT2-I versus other oral anti-diabetic (OAD) agents alone. Methods In this multicenter international registry, all diabetic patients with AMI treated with percutaneous coronary intervention (PCI) between 2018 and 2021 were enrolled. Based on the admission anti-diabetic therapy, patients were divided into those receiving SGLT2-I versus other OAD agents alone. Patients on insulin therapy alone or combined with OAD agents or with unavailable admission medical therapy were excluded from the study. Further exclusion criteria encompassed AMI (mostly NSTEMI) treated with coronary artery bypass grafting (CABG) after the CAG, severe valvular heart disease, prosthetic heart valves, severe anemia, major acute bleeding, pulmonary embolism, fever (38° C), chronic renal failure (glomerular filtration rate & lt; 30 mL/min/1.73 m2), autoimmune diseases, malignancies and congenital heart disease. The following inflammatory markers were evaluated at different time points: total white blood cell, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and neutrophil-to-platelet ratio (NPR), C-reactive protein. Infarct size was assessed by peak troponin levels and echocardiographic parameters. Results The final study population consisted of 583 patients hospitalized for AMI (both STEMI and NSTEMI) classified as SGLT2-I users (n = 98) versus other OAD agents alone (n = 485). Admission hyperglycemia was more prevalent among the other OAD agents group. Reduced infarct size was detected in patients treated with SGLT2-I compared to those treated with other OAD agents alone. Both at admission, and after 24 hours, inflammatory indices were significantly higher in patients treated with other OAD agents alone, with a significant increase in neutrophils levels at 24 hours, compared to the SGLT2-I group. In multivariate analysis, SGLT2-I emerged as a significant predictor of reduced inflammatory response (OR 0.45, 95%CI 0.27–0.75, p = 0.002), together with peak troponin values, independently of age, admission creatinine values and admission glycemia. Conclusions Type 2 Diabetic patients hospitalized for AMI and receiving SGLT2-I exhibited modest inflammatory response and myocardial damage/infarct size compared to other OAD agents alone, independently of glucose-metabolic control. Our findings pave the way for new pathophysiological and therapeutic insights regarding the cardioprotective effect of SGLT2-I in the setting of coronary artery disease.

    Abstract: Sodium-glucose co-transporter 2 inhibitors (SGLT2-I) receive intense clinical interest in patients with and without type 2 diabetes mellitus (T2DM) for their pleiotropic beneficial effects. Objectives To investigate in-hospital and long-term prognosis in a cohort of T2DM patients presenting with acute myocardial infarction (AMI) treated with SGLT2-I versus other oral anti-diabetic (OAD) agents (non-SGLT2-I users). Methods In this multicenter international registry all consecutive diabetic AMI patients undergoing percutaneous coronary intervention (PCI) between 2018 and 2021 were enrolled and, based on the admission anti-diabetic therapy, divided into SGLT-I users versus non-SGLT2-I users. In-hospital outcomes included cardiovascular death, recurrent AMI, occurrence of arrhythmias, and contrast-induced acute kidney injury (CI-AKI). Long-term outcomes were cardiovascular mortality, recurrent AMI, heart failure (HF) hospitalization, and their composite (MACE). Results The study population consisted of 646 AMI patients (with or without ST-segment elevation): 111 SGLT2-I users and 535 non-SGLT-I users. The use of SGLT2-I was associated with a significantly lower in-hospital cardiovascular death, arrhythmic burden, and occurrence of CI-AKI (all p & lt;0.05). During a median follow-up of 24±13 months, cardiovascular mortality, HF hospitalization and the composite endpoint were lower for SGLT2-I users compared to non-SGLT2-I patients (p & lt;0.04 for all). After adjusting for confounding factors, the use of SGLT2-I was identified as independent predictor of HF hospitalization (HR=0.46; 95%CI:0.21-0.98; p=0.041) and MACE occurrence (HR=0.57; 95%CI:0.33-0.99; p=0.039). Conclusions In T2DM AMI patients, the use of SGLT2-I was associated with a lower risk of adverse cardiovascular outcomes during index hospitalization and long-term follow-up. Our findings provide new insights into the cardioprotective effects of SGLT2-I in the setting of AMI.

Whether this holds true in patients with reduced left ventricular ejection fraction (LVEF) is unclear. To investigate whether FFR provides adjunctive clinical benefit compared to coronary angiography in deferring revascularization of patients with intermediate coronary stenoses and reduced LVEF. Methods and results Consecutive patients (n = 4577) with reduced LVEF (≤50%) undergoing coronary angiography between 2002 and 2010 were screened. We eventually included patients with at least one intermediate coronary stenosis (diameter stenosis ≥40%) in whom revascularization was deferred based either on angiography plus FFR (FFR-guided) or angiography alone (angiography-guided). The primary endpoint of the study was the cumulative incidence of all-cause death at 10 years. The secondary endpoint [the incidence of major adverse cardiovascular and cerebrovascular events (MACCE)], was a composite of all-cause death, myocardial infarction, any revascularization and stroke. A total of 840 patients were included (206 in the FFR-guided and 634 in the angiography-guided group). Median clinical follow-up was 7 years [IQR: (3.22–11.08)] . After 1:1 propensity score matching, baseline characteristics between the two groups were similar. All-cause death was significantly lower in the FFR-guided group compared with the angiography-guided group [94 (45.6%) vs. 119 (57.8%), HR: 0.65 (95% CI: 0.49–0.85), P  & lt; 0.01]. The rate of major adverse cardiovascular and cerebrovascular events [(MACCE), a composite of all-cause death, myocardial infarction, any revascularization, and stroke) was lower in the FFR-guided group [123 (59.7%) vs. 139 (67.5%), HR: 0.75 (95% CI: 0.59–0.95), P = 0.02] . Conclusions In patients with reduced LVEF, deferring revascularization of intermediate coronary stenoses based on FFR is associated with a lower incidence of death and MACCE at 10 years.

    Abstract: The bolus thermodilution-derived index of microcirculatory resistance (IMR) has emerged over years as the standard of reference to invasively define coronary microvascular dysfunction (CMD). However, the technique still presents some limitations, mainly related to the fact that manual injection of saline bolus accounts for some variance in the measurements. Continuous intracoronary thermodilution has been recently introduced as a tool to directly quantify absolute coronary flow and microvascular resistance both at rest and during hyperemia and has shown to be safe and operator independent. Microvascular resistance reserve (MRR), derived from continuous thermodilution, has been validated as novel index specific for microcirculation and independent from myocardial mass. Purpose To compare head-to-head the intra-observer repeatability of bolus and continuous thermodilution for assessing microvascular function. Methods Patients undergoing coronary angiography in the absence of obstructive coronary artery disease were prospectively enrolled. Bolus and continuous intracoronary thermodilution measurements were performed in duplicates in the left anterior descending artery (LAD). Patients were randomly assigned in a 1:1 ratio to undergo first bolus thermodilution or first continuous thermodilution assessment. Results A total of 102 patients were enrolled. Average FFR was 0.86±0.06. Coronary Flow Reserve (CFR) calculated with continuous thermodilution (CFRthermo) was significantly lower than bolus thermodilution-derived CFR (CFRbolus) (2.63±0.65 and 3.29±1.17, respectively, p & lt;0.001). CFRthermo showed a lower variability and a higher agreement than CFRbolus (variability 12.74 ± 10.41% vs 31.26±24.85%, respectively, p & lt;0.001; ICC= 0.78 (0.70-0.85) and 0.48 (0.32-0.62), respectively, p & lt;0.001, Figure 1). Both MRR and IMR showed a good agreement (ICC 0.81 (0.74-0.87) and 0.80 (0.71-0.86)) but the variability of the MRR was significantly lower (12.44 ± 10.06% vs 24.24±19.27, respectively, p & lt;0.001, figure 1). Reproducibility data of all indices derived from duplicated measurements of bolus and continuous thermodilution are reported in Figure 2. Conclusion Continuous intracoronary thermodilution has a higher repeatability than bolus thermodilution in the assessment of CMD.
