Clinical outcomes of left atrial appendage occlusion in patients with previous intracranial or gastrointestinal bleeding: Insights from the LOGIC (Left atrial appendage Occlusion in patients with Gastrointestinal or IntraCranial bleeding) International Multicenter Registry.

AIMS: To compare outcomes of patients who underwent left atrial appendage occlusion (LAAO) for nonvalvular atrial fibrillation (NVAF) and contraindication to anticoagulants due to history of either gastrointestinal (GI) or intracranial (IC) bleeding. METHODS: Patients with NVAF that underwent LAAO for GI or IC bleeding from seven centers were included in this observational study. Baseline characteristics, procedural features, and follow-up data were collected, and compared between the two groups. The primary outcomes were incidence of ischemic and hemorrhagic events at 12-month. RESULTS: Six hundred twenty-eight patients were included, 57% with previous GI-bleeding, and 43% with previous IC-bleeding. Median CHA 2 DS 2-VASc score was 4 (interquartile range [IQRs]: 3-5) for both GI-bleeding and IC-bleeding patients, while GI-bleeding patients had a higher HAS-BLED score (4 [IQRs: 3-4] vs. 3 [IQRs]: 2-3]; p = 0.001). At 12-month follow-up, relative risk reduction for stroke was similar between the two groups. The GI-bleeding group had more hemorrhagic events compared to IC-bleeding group (any bleeding 8.4% vs. 3.2%; p = 0.012; major bleeding BARC 3-5: 4.3% vs. 1.8; p = 0.010). At multivariate analysis history of GI bleeding was an independent predictor of hemorrhagic events (adjusted HR: 2.39, 95% confidence interval: 1.02-5.63; p = 0.047). CONCLUSIONS: Outcomes after LAAO may be affected by the different indications for the procedure. In our study, GI-bleeding and IC-bleeding as indication to LAAO differ in their baseline characteristics. LAAO confirms its efficacy in ischemic risk reduction in both groups, while GI bleeding seems to be an independent predictor of bleeding recurrence at 12 months behind the antithrombotic regimen.

Transcatheter aortic valve implantation for severe pure aortic regurgitation due to active aortitis.

Aortitis is an uncommon systemic inflammatory disease affecting the aorta and its main branches. Severe aortic regurgitation (AR) represents a fearsome complication of aortitis and is associated with an increased mortality rate. Surgical aortic valve replacement represents the only treatment choice for these patients. However, it is associated with a higher risk of medium to long-term complications such as prosthetic valve detachment. This is the first reported case where severe AR secondary to aortitis was managed with transcatheter aortic valve implantation (TAVI). TAVI was safe and effective in this clinical setting and may be considered a viable alternative to high-risk surgery in these complex patients.

Iatrogenic aorta-coronary dissection: Case report and systematic review.

OBJECTIVES AND BACKGROUND: Iatrogenic aorto-coronary dissection (ICD) is one of the most feared complications of interventional cardiology. Although rare, it is characterized by anterograde coronary ischemia and a concomitant aortic dissection, with potentially fatal consequences. METHODS: We present an example case of IACD and an accurate case-series review of the literature including 125 published cases. RESULTS: There were no significant predisposing factors and the IACD occurred equally in elective and urgent procedures. A significant number of IACDs were associated with CTO procedures. The factors associated with a worse outcome were hemodynamic instability, the presence of anterograde ischemia, and the extent of dissection according to the Dunning classification. Bail-out stenting was the most used strategy and its failure was associated with mortality. CONCLUSION: The main features of IACD are anterograde ischemia, retrograde dissection, and hemodynamic instability, each of them should be addressed with no time delay, possibly with bailout stenting, the most employed exit-strategy. According to our proposed algorithm, a shock team approach is required to coordinate the interdisciplinary skills and enabled patients to receive the best treatment.

Computed tomography analysis of coronary ostia location following valve-in-valve transcatheter aortic valve replacement with the ACURATE neo valve: Implications for coronary access.

BACKGROUND: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) is an emerging alternative to re-do surgery. However, the challenge of coronary access (CA) following ViV-TAVR is a potential limitation as TAVR expands to younger lower-risk populations. OBJECTIVES: Using post-implantation computed tomography (CT) scans to evaluate the geometrical relationship between coronary ostia and valve frame in patients undergoing ViV-TAVR with the ACURATE neo valve. METHODS: Post-implant CT scans of 18 out of 20 consecutive patients treated with the ACURATE neo valve were analyzed. Coronary ostia location in relation to the highest plane (HP) (highest point of the ACURATE neo or surgical valve) was determined. Ostia located below the highest plan were further subclassified according to the gap available between the transcatheter heart valve frame and ostium (transcatheter-to-coronary [TTC] distance). The impact implantation depth has on these geometrical relationships was evaluated. RESULTS: A total of 21 out of 36 coronary ostia (58%) were located below the level of the HP with the left coronary artery (36%) more likely to be affected than the right (22%). Further sub-classification of these ostia revealed a large (>6 mm), moderate (4-6 mm), and small (<4 mm) TTC distance in 57% (12/21), 38% (8/21), and in 6% (1/18) of cases, respectively. At an implantation depth <4 mm compared to >4 mm, all ostia were located below the HP with no difference in post-procedural mean gradients (14.5 mmHg ± 4.7 vs. 12.6 mmHg ± 5.8; p = .5, 95%CI 3.8-7.5). CONCLUSIONS: CA following ACURATE neo implantation for ViV-TAVR could potentially be challenging in a significant proportion of patients and specific consideration should be given to the implantation depth.

Sirolimus-Eluting Magnesium Resorbable Scaffold Implantation in Patients with Acute Myocardial Infarction.

To date, very little is known about the performance of a sirolimus-eluting bioresorbable magnesium scaffold (Mg-BRS) in patients with acute myocardial infarction (AMI). A multicenter cohort analysis was performed on 69 consecutive AMI subjects treated with Mg-BRS. Procedural success was obtained in all cases, and no in-hospital events were reported. At 9-month follow-up, no cardiac death, target-vessel myocardial infarction, ischemia-driven target lesion revascularization, or Mg-BRS thrombosis was reported. Although our analysis showed encouraging results, larger studies and longer-term follow-up are needed to better understand the potential benefits associated with the use of a Mg-BRS in AMI patients.

Bleeding Risk Scores and Scales of Frailty for the Prediction of Haemorrhagic Events in Older Adults with Acute Coronary Syndrome: Insights from the FRASER study.

PURPOSE: Hitherto, no study has yielded important information on whether the scales of frailty may improve the ability to discriminate the risk of haemorrhages in older adults admitted to hospital for acute coronary syndrome (ACS). The aim of this study is to investigate whether frailty scales would predict the 1-year occurrence of haemorrhagic events and if they confer a significant incremental prognostic value over the bleeding risk scores. METHODS: The present study involved 346 ACS patients aged ≥ 70 years enrolled in the FRASER study. Seven different scales of frailty and PARIS, PRECISE-DAPT and BleeMACS bleeding risk scores were available for each patient. The outcomes were the 1-year BARC 3-5 and 2 bleeding events. RESULTS: Adherence to antiplatelet treatment at 1, 6 and 12 months was 98%, 87% and 78%, respectively. At 1-year, 14 (4%) and 30 (9%) patients presented BARC 3-5 and 2 bleedings, respectively. Bleeding risk scores and four scales of frailty (namely Short Physical Performance Battery, Columbia, Edmonton and Clinical Frailty Scale) significantly discriminated the occurrence of BARC 3-5 events. The addition of the scales of frailty to bleeding risk scores did not lead to a significant improvement in the ability to predict BARC 3-5 bleedings. Neither the bleeding risk scores nor the scales of frailty predicted BARC 2 bleedings. CONCLUSIONS: Both the bleeding risk scores and the scales of frailty predicted BARC 3-5 haemorrhages. However, integrating the scales of frailty with the bleeding risk scores did not improve their discriminative ability. CLINICAL TRIAL REGISTRATION: www.clinicaltrials.gov: NCT02386124.

Angina and chronic obstructive pulmonary disease: facing the perfect storm.

The association of chronic obstructive pulmonary disease (COPD) and ischaemic heart disease (IHD) is challenging both in terms of prognosis and of pharmacological treatment. An 83-year-old Caucasian male patient has chronic kidney disease, COPD, previous myocardial infarction, coronary artery bypass graft with left internal mammary artery (LIMA) on left anterior descending (LAD), saphenous vein graft (SVG) on obtuse marginal (OM)1 and on right coronary artery, and percutaneous coronary intervention (PCI) on LAD (occlusion of LIMA) and on SVG for OM1 (SVG critical stenosis). Recently, the patient complained worsening angina [Canadian Cardiovascular Society (CCS) III] and had residual ischaemia in the anterior wall after an unsuccessful attempt of PCI was performed on LAD for in-stent occlusion due to restenosis. Bisoprolol uptitration failed due to worsening of pulmonary function at spirometry. For this reason, ivabradine 5 mg b.i.d. was added to bisoprolol. Afterwards, the patient referred amelioration of symptoms and he is actually in CCS Class I. The control spirometry showed moderate obstruction comparable to his chronic situation. Patients with IHD and COPD often do not receive ß-blockers due to the fear of adverse effects. However, cardioselective ß-blockers do not worsen pulmonary function while they reduce mortality in COPD patients. In this setting, ivabradine could be extremely helpful in order to control symptoms since it is effective in patients with asthma and COPD, with no alteration in respiratory function or symptoms and improves exercise capacity and functional class in COPD patients.

Physical activity intervention for elderly patients with reduced physical performance after acute coronary syndrome (HULK study): rationale and design of a randomized clinical trial.

BACKGROUND: Reduced physical performance and impaired mobility are common in elderly patients after acute coronary syndrome (ACS) and they represent independent risk factors for disability, morbidity, hospital readmission and mortality. Regular physical exercise represents a means for improving functional capacity. Nevertheless, its clinical benefit has been less investigated in elderly patients in the early phase after ACS. The HULK trial aims to investigate the clinical benefit of an early, tailored low-cost physical activity intervention in comparison to standard of care in elderly ACS patients with reduced physical performance. DESIGN: HULK is an investigator-initiated, prospective multicenter randomized controlled trial (NCT03021044). After successful management of the ACS acute phase and uneventful first 1 month, elderly (≥70 years) patients showing reduced physical performance are randomized (1:1 ratio) to either standard of care or physical activity intervention. Reduced physical performance is defined as a short physical performance battery (SPPB) score of 4-9. The early, tailored, low-cost physical intervention includes 4 sessions of physical activity with a supervisor and an home-based program of physical exercise. The chosen primary endpoint is the 6-month SPPB value. Secondary endpoints briefly include quality of life, on-treatment platelet reactivity, some laboratory data and clinical adverse events. To demonstrate an increase of at least one SPPB point in the experimental arm, a sample size of 226 patients is needed. CONCLUSIONS: The HULK study will test the hypothesis that an early, tailored low-cost physical activity intervention improves physical performance, quality of life, frailty status and outcome in elderly ACS patients with reduced physical performance.

Procedural success in transaxillary transcatheter aortic valve implantation according to type of transcatheter heart valve: results from the multicenter TAXI registry.

BACKGROUND: Transaxillary (TAx) transcatheter aortic valve implantation (TAVI) is a preferred alternative access in patients ineligible for transfemoral TAVI. AIMS: This study used the Trans-AXillary Intervention (TAXI) registry to compare procedural success according to different types of transcatheter heart valves (THV). METHODS: For the TAXI registry anonymized data of patients treated with TAx-TAVI were collected from 18 centers. Acute procedural, early and 1-month clinical outcomes were adjudicated in accordance with standardized VARC-3 definitions. RESULTS: From 432 patients, 368 patients (85.3%, SE group) received self-expanding (SE) THV and 64 patients (14.8%, BE group) received balloon-expandable (BE) THV. Imaging revealed lower axillary artery diameters in the SE group (max/min diameter in mm: 8.4/6.6 vs 9.4/6.8 mm; p < 0.001/p = 0.04) but a higher proportion of axillary tortuosity in BE group (62/368, 23.6% vs 26/64, 42.6%; p = 0.004) with steeper aorta-left ventricle (LV) inflow (55° vs 51°; p = 0.002) and left ventricular outflow tract (LVOT)-LV inflow angles (40.0° vs 24.5°; 0.002). TAx-TAVI was more often conducted by right sided axillary artery in the BE group (33/368, 9.0% vs 17/64, 26.6%; p < 0.001). Device success was higher in the SE group (317/368, 86.1% vs 44/64, 68.8%, p = 0.0015). In logistic regression analysis, BE THV were a risk factor for vascular complications and axillary stent implantation. CONCLUSIONS: Both, SE and BE THV can be safely used in TAx-TAVI. However, SE THV were more often used and were associated with a higher rate of device success. While SE THV were associated with lower rates of vascular complications, BE THV were more often used in cases with challenging anatomical circumstances.

Safety and efficacy of new-generation coronary bioresorbable scaffolds.

INTRODUCTION: The concept of bioresorbable scaffolds (BRS) was born with the aim to reduce the rate of late and very late cardiac events related to drug-eluting stents. However, first-generation BRS failed to prove their short-term safety and efficacy. Based on data derived from early investigations, new-generation BRS have been developed and tested in preliminary studies. The present review's focus was to summarize the mechanical characteristics of these new scaffolds and the clinical evidence of their safety and efficacy. EVIDENCE ACQUISITION: This systematic review was performed following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). PUBMED, Google Scholar, and Biomed central databases were analyzed. Only papers published in English and in peer-reviewed journals were selected to summarize current evidence about new generation BRS, with CE mark approval. Overall, 23 studies were included. EVIDENCE SYNTHESIS: Data obtained from selected studies assessing the safety and efficacy of new generation BRS are encouraging. This is thanks to the progressive development of scaffolds with a different backbone structure and struts thickness that guarantee higher radial strength, flexibility, and resistance to fracture. These characteristics led to low rates of major adverse cardiac events and device-oriented composite endpoint at follow-up. CONCLUSIONS: New-generation BRS have a good safety profile in stable patients with simple lesions, supported by a meticulous implantation technique. The first studies were performed on a small population with short-term follow-up, therefore new randomized clinical trials and registries are needed to expand the preliminary findings.

Latest Developments in Robotic Percutaneous Coronary Interventions.

Since the first robotic-assisted percutaneous coronary intervention procedure (R-PCI) was performed in 2004, there has been a steady evolution in robotic technology, combined with a growth in the number of robotic installations worldwide and operator experience. This review summarises the latest developments in R-PCI with a focus on developments in robotic technology, procedural complexity, tele-stenting and training methods, which have all contributed to the global expansion in R-PCI.

Long-term outcomes of patients treated with sirolimus-eluting resorbable magnesium scaffolds: Insights from the SHERPA-MAGIC study.

BACKGROUND: The resorbable magnesium scaffold (RMS) is a second-generation bioresorbable scaffold (BRS) that has shown conflicting results in previous studies. These findings suggest that patient selection and implantation technique may have an impact on clinical outcomes. This study aimed to investigate the safety and long-term effectiveness of RMS in a narrowly selected population. METHODS: SHERPA-MAGIC is an investigator-driven, multicenter, prospective, single-arm study that enrolled patients undergoing BRS coronary implantation in 18 Italian centers. The present analysis considered the first 543 enrolled patients treated with RMS, with a minimum follow-up of 1 year. The study protocol included strict criteria for patient selection and standardization of RMS implantation. The primary outcome was the occurrence of the vessel-oriented composite endpoints (VOCE), including cardiac death, target vessel myocardial infarction, and ischemia-driven target vessel revascularization. RESULTS: Overall, 635 vessels were treated. The 1-year cumulative occurrence of VOCE was 22 (3.5%, 95% CI 2.2%-5.2%), which was significantly lower than the prespecified estimation (from 5.5% to 8.5%). At the median follow-up of 3.5 [2.6-4.3] years, there were 3 (0.5%) cardiac deaths, 12 (1.9%) target vessel myocardial infarctions, and 33 (5.2%) ischemia-driven target vessel revascularizations. A total of 37 (5.8%, 95%CI 4.1%-7.9%) VOCEs were detected. Scaffold thrombosis occurred in 4 (0.6%, 95%CI 0.1%-1.6%) cases. Patient-level analysis confirmed the findings of the vessel-level analysis. CONCLUSIONS: These results confirm the safety and performance of RMS technology. If confirmed in randomized controlled trials, they may rekindle interest in the use of scaffolds in daily practice.

Symptoms-to-emergency-call timing delay in acute coronary syndrome before and during COVID-19: independent predictors and their impact on mortality.

BACKGROUND: The COVID-19 pandemic severely impacted global health. The aim of this study was to compare predictors of symptoms-to-emergency-call timing delay in acute coronary syndrome (ACS) and their impact on mortality before and during the COVID-19 outbreak. METHODS: We collected sociodemographic, clinical data, procedural features, preadmission and intra-hospital outcomes of consecutive patients admitted for ACS in seventeen Italian centers from March to April 2018, 2019, and 2020. RESULTS: In 2020, a 32.92% reduction in ACS admissions was observed compared to 2018 and 2019. Unstable angina, typical and atypical symptoms, and intermittent angina were identified as significant predictors of symptoms-to-emergency-call timing delay before and during the COVID-19 pandemic (P<0.005 for all the items). Differently from 2018-2019, during the pandemic, hypertension and dyspnea (P=0.002 versus P=0.490 and P=0.001 vs. P=0.761 for 2018-2019 and 2020, respectively) did not result as predictors of delay in symptoms-to-emergency-call timing. Among these predictors, only the atypical symptoms (HR 3.36; 95% CI: 1.172-9.667, P=0.024) in 2020 and the dyspnea (HR 2.64; 95% CI: 1.345-5.190, P=0.005) in 2018-2019 resulted significantly associated with higher mortality. Finally, the family attendance at the onset of the symptoms resulted in a reduction in symptoms-to-emergency-call timing (in 2020 P<0.001; CI: -1710.73; -493.19) and in a trend of reduced mortality (HR 0.31; 95% CI: 0.089-1.079, P=0.066) in 2020. CONCLUSIONS: During the COVID-19 outbreak, atypical symptoms and family attendance at ACS onset were identified, respectively, as adverse and favorable predictors of symptoms-to-emergency-call timing delay and mortality.

Coronary access following ACURATE neo implantation for transcatheter aortic valve-in-valve implantation: Ex vivo analysis in patient-specific anatomies.

Background: Coronary access after transcatheter aortic valve implantation (TAVI) with supra-annular self-expandable valves may be challenging or un-feasible. There is little data concerning coronary access following transcatheter aortic valve-in-valve implantation (ViV-TAVI) for degenerated surgical bioprosthesis. Aims: To evaluate the feasibility and challenge of coronary access after ViV-TAVI with the supra-annular self-expandable ACURATE neo valve. Materials and methods: Sixteen patients underwent ViV-TAVI with the ACURATE neo valve. Post-procedural computed tomography (CT) was used to create 3D-printed life-sized patient-specific models for bench-testing of coronary cannulation. Primary endpoint was feasibility of diagnostic angiography and PCI. Secondary endpoints included incidence of challenging cannulation for both diagnostic catheters (DC) and guiding catheters (GC). The association between challenging cannulations with aortic and transcatheter/surgical valve geometry was evaluated using pre and post-procedural CT scans. Results: Diagnostic angiography and PCI were feasible for 97 and 95% of models respectively. All non-feasible procedures occurred in ostia that underwent prophylactic "chimney" stenting. DC cannulation was challenging in 17% of models and was associated with a narrower SoV width (30 vs. 35 mm, p < 0.01), STJ width (28 vs. 32 mm, p < 0.05) and shorter STJ height (15 vs. 17 mm, p < 0.05). GC cannulation was challenging in 23% of models and was associated with narrower STJ width (28 vs. 32 mm, p < 0.05), smaller transcatheter-to-coronary distance (5 vs. 9.2 mm, p < 0.05) and a worse coronary-commissural overlap angle (14.3° vs. 25.6 o , p < 0.01). Advanced techniques to achieve GC cannulation were required in 22/64 (34%) of cases. Conclusion: In this exploratory bench analysis, diagnostic angiography and PCI was feasible in almost all cases following ViV-TAVI with the ACURATE neo valve. Prophylactic coronary stenting, higher implantation, narrower aortic sinus dimensions and commissural misalignment were associated with an increased challenge of coronary cannulation.

Coronary Computed Tomography Angiography for the Assessment of Sirolimus-Eluting Resorbable Magnesium Scaffold.

BACKGROUND: Little evidence to date has described the feasibility and diagnostic accuracy of coronary computed tomography angiography (CCTA) with noninvasive fractional flow reserve (CT-FFR) in coronary vessels with resorbable magnesium scaffold (RMS). METHODS: The SHERPA-MAGIC is a prospective study enrolling patients receiving RMS. The present analysis considered patients undergoing CCTA 18 months after the index procedure. CCTA images were employed to investigate reabsorption status, luminal measurements, and noninvasive FFR. Three-year follow-up was available for all patients. RESULTS: Overall, 26 patients with a total of 29 coronary arteries treated with 35 RMS were considered. The most frequently involved vessel was left anterior descendent (LAD). Median stent length was 25 (20-25) mm, with a median diameter of 3 (3-3.5) mm. At 18-month CCTA, all scaffolded segments were patent. Complete RMS reabsorption was observed in 27 (93%, 95% CI 77-99%) cases. Median minimal lumen diameter (MLD) and area (MLA) of the scaffolded segments were 2.5 [2.1-2.8] mm and 6.4 [4.4-8.4] mm2, respectively. Median CT-FFR was 0.88 [0.81-0.91]. Only one (3.5%) vessel showed a flow-limiting CT-FFR value ≤0.80. During the 3-year follow-up, only one (4%) adverse event was observed. Conclusions: In patients undergoing RMS implantation, CCTA including noninvasive CT-FFR evaluation is feasible and allows investigation of long-term RMS performance.

The Incidence and Impact of In-Hospital Bleeding in Patients with Acute Coronary Syndrome during the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic increased the complexity of the clinical management and pharmacological treatment of patients presenting with an Acute Coronary Syndrome (ACS). AIM: to explore the incidence and prognostic impact of in-hospital bleeding in patients presenting with ACS before and during the COVID-19 pandemic. METHODS: We evaluated in-hospital Thrombolysis In Myocardial Infarction (TIMI) major and minor bleeding among 2851 patients with ACS from 17 Italian centers during the first wave of the COVID-19 pandemic (i.e., March-April 2020) and in the same period in the previous two years. RESULTS: The incidence of in-hospital TIMI major and minor bleeding was similar before and during the COVID-19 pandemic. TIMI major or minor bleeding was associated with a significant threefold increase in all-cause mortality, with a similar prognostic impact before and during the COVID-19 pandemic. CONCLUSIONS: the incidence and clinical impact of in-hospital bleeding in ACS patients was similar before and during the COVID-19 pandemic. We confirmed a significant and sizable negative prognostic impact of in-hospital bleeding in ACS patients.

Percutaneous vs. surgical axillary access for transcatheter aortic valve implantation: the TAXI registry.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an established management strategy for severe aortic valve stenosis. Percutaneous axillary approach for TAVI holds the promise of improving safety without jeopardizing effectiveness in comparison to surgical access. We aimed at appraising the comparative effectiveness of percutaneous vs. surgical axillary approaches for TAVI. METHODS: We performed an international retrospective observational study using de-identified details on baseline, procedural, and 1-month follow-up features. Valve Academic Research Consortium (VARC)-3 criteria were applied throughout. Outcomes of interest were clinical events up to 1 month of follow-up, compared with unadjusted and propensity score-adjusted analyses. RESULTS: A total of 432 patients were included, 189 (43.8%) receiving surgical access, and 243 (56.2%) undergoing percutaneous access. Primary hemostasis failure was more common in the percutaneous group (13.2% vs. 4.2%, P<0.001), leading to more common use of covered stent implantation (13.2% vs. 3.7%, P<0.001). Irrespectively, percutaneous access was associated with shorter hospital stay (-2.6 days [95% confidence interval: -5.0; -0.1], P=0.038), a lower risk of major adverse events (a composite of death, myocardial infarction, stroke, type 3 bleeding, and major access-site related complication; odds ratio=0.44 [0.21; 0.95], P=0.036), major access-site non-vascular complications (odds ratio=0.21 [0.06; 0.77], P=0.018), and brachial plexus impairment (odds ratio=0.16 [0.03; 0.76], P=0.021), and shorter hospital stay (-2.6 days [-5.0; -0.1], P=0.038). CONCLUSIONS: Percutaneous axillary access provides similar or better results than surgical access in patients undergoing TAVI with absolute or relative contraindications to femoral access.

Lipid plaque burden in NSTE-ACS patients with or without COPD: insights from the SCAP Trial.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) patients have higher recurrence of adverse events and worse prognosis after acute coronary syndrome (ACS). The underlying pathophysiological mechanism is not fully elucidated. METHODS: In screening for COPD in ACS (SCAP) Trial (NCT02324660), ACS patients with smoking habit underwent a predischarge screening procedure to detect undiagnosed chronic obstructive pulmonary disease (UCOPD) confirmed with spirometry at 60 days. Patients were then categorized as UCOPD or no-COPD. In 65 NSTE-ACS patients, we performed near infrared spectroscopy (NIRS) in the culprit and at least one non-culprit vessel (151 vessels overall), and we calculated the SYNTAX I Score. Primary endpoint was max lipid core burden index (LCBI) 4 mm. Secondary endpoints were SYNTAX Score I and vessel LCBI. RESULTS: Max LCBI 4 mm and vessel LCBI were significantly higher in the UCOPD compared to the no-COPD group (UCOPD 388±122, no-COPD 264±131, P<0.001; UCOPD 118±50, no-COPD 82±42, P<0.001, respectively). UCOPD patients showed higher max LCBI 4 mm and LCBI vessel both in culprit and non-culprit vessels. SYNTAX Score I was comparable between the two groups (UCOPD: 13.5 [5.5-24], no-COPD: 12.5 [5-24.5], P=0.7). CONCLUSIONS: NSTE-ACS patients with UCOPD showed a higher LCBI compared to those without COPD, while SYNTAX Score I was comparable between the two groups.

Exercise intervention improves quality of life in older adults after myocardial infarction: randomised clinical trial.

OBJECTIVE: To establish the benefits of an early, tailored and low-cost exercise intervention in older patients hospitalised for acute coronary syndrome (ACS). METHODS: The study was a multicentre, randomised assessment of an exercise intervention in patients with ACS ≥70 years with reduced physical performance (as defined by the short physical performance battery (SPPB), value 4-9). The exercise intervention included four supervised sessions (1, 2, 3, 4 months after discharge) and home-based exercises. The control group attended a health education programme only. The outcomes were the 6-month and 1-year effects on physical performance, daily activities, anxiety/depression and quality of life. Finally, 1-year occurrence of adverse events was recorded. RESULTS: Overall, 235 patients with ACS (median age 76 (73-81) years) were randomised 1 month after ACS. Exercise and control groups were well balanced. Exercise intervention improved 6-month and 1-year grip strength and gait speed. Exercise intervention was associated with a better quality of life (as measured by EuroQol-visual analogue scale at 6 months 80 (70-90) vs 70 (50-80) points, p<0.001 and at 1 year 75 (70-87) vs 65 (50-80) points, p<0.001) and with a reduced perception of anxiety and/or depression (6 months: 21% vs 42%, p=0.001; 1 year 32% vs 47%, p=0.03). The occurrence of cardiac death and hospitalisation for cardiac cause was lower in the intervention group (7.5% vs 17%, p=0.04). CONCLUSIONS: The proposed early, tailored, low-cost exercise intervention improves mobility, daily activities, quality of life and outcomes in older patients with ACS. Larger studies are needed to confirm the clinical benefit. TRIAL REGISTRATION NUMBER: NCT03021044.

Nutritional status and all-cause mortality in older adults with acute coronary syndrome.

BACKGROUND & AIMS: The present analysis investigated the prevalence and the prognostic implication of nutritional status in older adults hospitalized for acute coronary syndrome (ACS). METHODS: The analysis is based on older ACS patients included in the FRASER and LONGEVO SCA studies. The Global Risk of Acute Coronary Events (GRACE) risk score was computed in all patients. Nutritional status was assessed with the Mini Nutritional Assessment-Short Form (MNA-SF, normal for values between 12 and 14, at risk of malnutrition for values between 8 and 11, and malnutrition for values ≤ 7). Physical performance was assessed with the Short Physical Performance Battery (SPPB). Primary outcome was all-cause mortality. RESULTS: The study included 908 patients. Overall, 35 patients (4%) were malnourished and 361 (40%) were at risk of malnutrition. After a median follow-up of 288 [187-370] days, the primary endpoint occurred in 94 (10.5%) patients. The mortality rate was 31% in malnourished subjects, 19% in at-risk patients, 3% in patients with a normal nutritional status (p < 0.001). MNA-SF emerged as an independent predictor of all-cause mortality (HR 0.76, 95%CI 0.68-0.84 for single change unit). The MNA-SF score improved the GRACE score's ability to discriminate subjects at risk of death (ΔC-statistic = 0.076, p < 0.001; ΔBIC -28; IDI 0.052, p < 0.001; NRI 0.793, p < 0.001). The prognostic value of MNA-SF was maintained also by including the SPPB score in the predictive model. CONCLUSION: s: The MNA-SF helped to identify malnutrition in older ACS patients. Moreover, the MNA-SF value is an independent predictor of all-cause mortality and it improves the predictive value of the GRACE risk score.
