BACKGROUND: The associations between deprivation and illness trajectory after hospitalisation for coronavirus disease-19 (COVID-19) are uncertain. METHODS: A prospective, multicentre cohort study was conducted on post-COVID-19 patients, enrolled either in-hospital or shortly post-discharge. Two evaluations were carried out: an initial assessment and a follow-up at 28-60 days post-discharge. The study encompassed research blood tests, patient-reported outcome measures, and multisystem imaging (including chest computed tomography (CT) with pulmonary and coronary angiography, cardiovascular and renal magnetic resonance imaging). Primary and secondary outcomes were analysed in relation to socioeconomic status, using the Scottish Index of Multiple Deprivation (SIMD). The EQ-5D-5L, Brief Illness Perception Questionnaire (BIPQ), Patient Health Questionnaire-4 (PHQ-4) for Anxiety and Depression, and the Duke Activity Status Index (DASI) were used to assess health status. RESULTS: Of the 252 enrolled patients (mean age 55.0 ± 12.0 years; 40% female; 23% with diabetes), deprivation status was linked with increased BMI and diabetes prevalence. 186 (74%) returned for the follow-up. Within this group, findings indicated associations between deprivation and lung abnormalities (p = 0.0085), coronary artery disease (p = 0.0128), and renal inflammation (p = 0.0421). Furthermore, patients with higher deprivation exhibited worse scores in health-related quality of life (EQ-5D-5L, p = 0.0084), illness perception (BIPQ, p = 0.0004), anxiety and depression levels (PHQ-4, p = 0.0038), and diminished physical activity (DASI, p = 0.002). At the 3-month mark, those with greater deprivation showed a higher frequency of referrals to secondary care due to ongoing COVID-19 symptoms (p = 0.0438). However, clinical outcomes were not influenced by deprivation. CONCLUSIONS: In a post-hospital COVID-19 population, socioeconomic deprivation was associated with impaired health status and secondary care episodes. Deprivation influences illness trajectory after COVID-19.
In our study, we aimed to understand how socioeconomic factors impact recovery from COVID-19 following hospitalisation. We followed 252 patients, collecting health data and utilising advanced imaging techniques. We discovered that individuals from deprived areas experienced more severe health complications, reported worse quality of life, and required more specialist care. However, their clinical outcomes were not significantly different. This underscores that socioeconomic deprivation affects health recovery, underlining the need for tailored care for these individuals. Our findings emphasise the importance of considering socioeconomic factors in recovery plans post-COVID-19, potentially improving healthcare for those in deprived areas.

Importance: Surgical site infections (SSIs) represent a costly and preventable complication of cutaneous surgery. However, there is a paucity of randomized clinical trials investigating antibiotic prophylaxis for reducing SSIs in skin cancer surgery, and evidence-based guidelines are lacking. Incisional antibiotics have been shown to reduce the rate of SSIs before Mohs micrographic surgery, but this represents a small subset of skin cancer surgery. Objective: To determine whether microdosed incisional antibiotics reduce the rate of SSIs before skin cancer surgery. Design, Setting, and Participants: In this double-blind, controlled, parallel-design randomized clinical trial, adult patients presenting to a high-volume skin cancer treatment center in Auckland, New Zealand, for any form of skin cancer surgery over 6 months from February to July 2019 were included. Patient presentations were randomized to one of 3 treatment arms. Data were analyzed from October 2021 to February 2022. Interventions: Patients received an incision site injection of buffered local anesthetic alone (control), buffered local anesthetic with microdosed flucloxacillin (500 µg/mL), or buffered local anesthetic with microdosed clindamycin (500 µg/mL). Main Outcomes and Measures: The primary end point was the rate of postoperative SSI (calculated as number of lesions with SSI per total number of lesions in the group), defined as a standardized postoperative wound infection score of 5 or more. Results: A total of 681 patients (721 total presentations; 1133 total lesions) returned for postoperative assessments and were analyzed. Of these, 413 (60.6%) were male, and the mean (SD) age was 70.4 (14.8) years. Based on treatment received, the proportion of lesions exhibiting a postoperative wound infection score of 5 or greater was 5.7% (22 of 388) in the control arm, 5.3% (17 of 323) in the flucloxacillin arm, and 2.1% (9 of 422) in the clindamycin arm (P = .01 for clindamycin vs control). Findings were similar after adjusting for baseline differences among arms. Compared with lesions in the control arm (31 of 388 [8.0%]), significantly fewer lesions in the clindamycin arm (9 of 422 [2.1%]; P < .001) and flucloxacillin (13 of 323 [4.0%]; P = .03) arms required postoperative systemic antibiotics. Conclusions and Relevance: This study evaluated the use of incisional antibiotics for SSI prophylaxis in general skin cancer surgery and compared the efficacy of flucloxacillin vs clindamycin relative to control in cutaneous surgery. The significant reduction in SSI with locally applied microdosed incisional clindamycin provides robust evidence to inform treatment guidelines in this area, which are currently lacking.

BACKGROUND: We investigated the associations of healthcare worker status with multisystem illness trajectory in hospitalised post-COVID-19 individuals. METHODS AND RESULTS: One hundred and sixty-eight patients were evaluated 28-60 days after the last episode of hospital care. Thirty-six (21%) were healthcare workers. Compared with non-healthcare workers, healthcare workers were of similar age (51.3 (8.7) years vs 55.0 (12.4) years; p=0.09) more often women (26 (72%) vs 48 (38%); p<0.01) and had lower 10-year cardiovascular risk (%) (8.1 (7.9) vs 15.0 (11.5); p<0.01) and Coronavirus Clinical Characterisation Consortium in-hospital mortality risk (7.3 (10.2) vs 12.7 (9.8); p<0.01). Healthcare worker status associated with less acute inflammation (peak C reactive protein 48 mg/L (IQR: 14-165) vs 112 mg/L (52-181)), milder illness reflected by WHO clinical severity score distribution (p=0.04) and shorter duration of admission (4 days (IQR: 2-6) vs 6 days (3-12)).In adjusted multivariate logistic regression analysis, healthcare worker status associated with a binary classification (probable/very likely vs not present/unlikely) of adjudicated myocarditis (OR: 2.99; 95% CI (1.01 to 8.89) by 28-60 days postdischarge).After a mean (SD, range) duration of follow-up after hospital discharge of 450 (88) days (range 290, 627 days), fewer healthcare workers died or were rehospitalised (1 (3%) vs 22 (17%); p=0.038) and secondary care referrals for post-COVID-19 syndrome were common (42%) and similar to non-healthcare workers (38%; p=0.934). CONCLUSION: Healthcare worker status was independently associated with the likelihood of adjudicated myocarditis, despite better antecedent health. Two in five healthcare workers had a secondary care referral for post-COVID-19 syndrome. TRIAL REGISTRATION NUMBER: NCT04403607.

Stratifying prognosis following coronary bifurcation percutaneous coronary intervention (PCI) is an unmet clinical need that may be fulfilled through the adoption of machine learning (ML) algorithms to refine outcome predictions. We sought to develop an ML-based risk stratification model built on clinical, anatomical, and procedural features to predict all-cause mortality following contemporary bifurcation PCI. Multiple ML models to predict all-cause mortality were tested on a cohort of 2393 patients (training, n = 1795; internal validation, n = 598) undergoing bifurcation PCI with contemporary stents from the real-world RAIN registry. Twenty-five commonly available patient-/lesion-related features were selected to train ML models. The best model was validated in an external cohort of 1701 patients undergoing bifurcation PCI from the DUTCH PEERS and BIO-RESORT trial cohorts. At ROC curves, the AUC for the prediction of 2-year mortality was 0.79 (0.74-0.83) in the overall population, 0.74 (0.62-0.85) at internal validation and 0.71 (0.62-0.79) at external validation. Performance at risk ranking analysis, k-center cross-validation, and continual learning confirmed the generalizability of the models, also available as an online interface. The RAIN-ML prediction model represents the first tool combining clinical, anatomical, and procedural features to predict all-cause mortality among patients undergoing contemporary bifurcation PCI with reliable performance.
RESUMO
AIM: The impact of Grade III coronary perforations (G3-CP) in the setting of CTO-PCI is not well assessed. METHODS AND RESULTS: We reviewed 7773 CTO-PCI and 98,819 non CTO-PCI performed in 10 European centers: G3 perforation occurred in 87 patients (1.1%) during CTO PCI and 224 patients (0.22%) during non CTO-PCI (p < 0.001). G3-CP involved the CTO segment in 68% of patients and the retrograde channels in 14% of cases. In the CTO PCI group, wire induced G3-CP (50.5% vs. 32.5%, p = 0.02) occurred predominantly when dedicated CTO tapered and highly penetrative wires were used. Intra-procedural and in-hospital death rates were 4.6% vs. 5.8% and 3.6% vs. 7.5% respectively for CTO PCI and non-CTO PCI groups (p = NS). At a median follow up of 24 months, the overall mortality and MAE were respectively 7.8% and MAE 19% without difference among groups. CONCLUSIONS: We showed similar in-hospital and long-term outcomes when G3 perforations occurred during CTO PCI and non CTO-PCI.

The pathophysiology and trajectory of post-Coronavirus Disease 2019 (COVID-19) syndrome is uncertain. To clarify multisystem involvement, we undertook a prospective cohort study including patients who had been hospitalized with COVID-19 (ClinicalTrials.gov ID NCT04403607 ). Serial blood biomarkers, digital electrocardiography and patient-reported outcome measures were obtained in-hospital and at 28-60 days post-discharge when multisystem imaging using chest computed tomography with pulmonary and coronary angiography and cardio-renal magnetic resonance imaging was also obtained. Longer-term clinical outcomes were assessed using electronic health records. Compared to controls (n = 29), at 28-60 days post-discharge, people with COVID-19 (n = 159; mean age, 55 years; 43% female) had persisting evidence of cardio-renal involvement and hemostasis pathway activation. The adjudicated likelihood of myocarditis was 'very likely' in 21 (13%) patients, 'probable' in 65 (41%) patients, 'unlikely' in 56 (35%) patients and 'not present' in 17 (11%) patients. At 28-60 days post-discharge, COVID-19 was associated with worse health-related quality of life (EQ-5D-5L score 0.77 (0.23) versus 0.87 (0.20)), anxiety and depression (PHQ-4 total score 3.59 (3.71) versus 1.28 (2.67)) and aerobic exercise capacity reflected by predicted maximal oxygen utilization (20.0 (7.6) versus 29.5 (8.0) ml/kg/min) (all P < 0.01). During follow-up (mean, 450 days), 24 (15%) patients and two (7%) controls died or were rehospitalized, and 108 (68%) patients and seven (26%) controls received outpatient secondary care (P = 0.017). The illness trajectory of patients after hospitalization with COVID-19 includes persisting multisystem abnormalities and health impairments that could lead to substantial demand on healthcare services in the future.

AIMS: The SYNTAX II study evaluated the impact of advances in percutaneous coronary intervention (PCI), integrated into a single revascularization strategy, on outcomes of patients with de novo three-vessel disease. The study employed decision-making utilizing the SYNTAX score II, use of coronary physiology, thin-strut biodegradable polymer drug-eluting stents, intravascular ultrasound, enhanced treatments of chronic total occlusions, and optimized medical therapy. Patients treated with this approach were compared with predefined patients from the SYNTAX I trial. METHODS AND RESULTS: SYNTAX II was a multicentre, single-arm, open-label study of patients requiring revascularization who demonstrated clinical equipoise for treatment with either coronary artery bypass grafting (CABG) or PCI, predicted by the SYNTAX score II. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which included any revascularization. The comparators were a matched PCI cohort trial and a matched CABG cohort, both from the SYNTAX I trial. At 5 years, MACCE rate in SYNTAX II was significantly lower than in the SYNTAX I PCI cohort (21.5% vs. 36.4%, P < 0.001). This reflected lower rates of revascularization (13.8% vs. 23.8%, P < 0.001), and myocardial infarction (MI) (2.7% vs. 10.4%, P < 0.001), consisting of both procedural MI (0.2% vs. 3.8%, P < 0.001) and spontaneous MI (2.3% vs. 6.9%, P = 0.004). All-cause mortality was lower in SYNTAX II (8.1% vs. 13.8%, P = 0.013) reflecting a lower rate of cardiac death (2.8% vs. 8.4%, P < 0.001). Major adverse cardiac and cerebrovascular events' outcomes at 5 years among patients in SYNTAX II and predefined patients in the SYNTAX I CABG cohort were similar (21.5% vs. 24.6%, P = 0.35). CONCLUSIONS: Use of the SYNTAX II PCI strategy in patients with de novo three-vessel disease led to improved and durable clinical results when compared to predefined patients treated with PCI in the original SYNTAX I trial. A predefined exploratory analysis found no significant difference in MACCE between SYNTAX II PCI and matched SYNTAX I CABG patients at 5-year follow-up.

OBJECTIVES: This study assesses the safety and efficacy of thin-strut stents in non-left main (non-LM) bifurcation coronary lesions. BACKGROUND: Thinner struts of recent drug-eluting stent (DES) devices are associated with improved outcomes, but data about their performance in challenging scenarios are scant. METHODS: RAIN was a retrospective multicenter registry enrolling patients with coronary bifurcation lesions or left main (LM) disease treated with thin-strut DESs. Target-lesion revascularization (TLR) was the primary endpoint, while major adverse clinical event (MACE) rate, a composite of all-cause death, myocardial infarction (MI), target-vessel revascularization (TVR), TLR, and stent thrombosis (ST), and its single components were the secondary endpoints. Multivariable analysis was performed to identify predictors of TLR. Outcome incidences according to stenting strategy (provisional vs 2-stent technique), use of final kissing balloon (FKB), and intravascular ultrasound/optical coherence tomography optimization were further investigated in prespecified subanalyses. RESULTS: A total of 1803 patients (59% acute coronary syndrome, 41% stable coronary artery disease) with non-LM bifurcations were enrolled. After a median follow-up of 12 months, TLR incidence was 2.5% (2.2% for provisional stenting and 3.5% for 2-stent technique). MACE rate was 9.4% (all-cause death, 4.1%; MI, 3.2%; TVR, 3.7%; definite ST, 1.1%). After multivariable adjustment, postdilation (hazard ratio [HR], 0.32; 95% confidence interval [CI], 0.15-0.71; P<.01) and provisional stenting (HR, 0.62; 95% CI, 0.55-0.89; P=.03) were associated with lower TLR rates. FKB was associated with a lower incidence of TLR in the 2-stent subgroup (P=.03). Intracoronary imaging had no significant impact on the primary endpoint. CONCLUSIONS: Thin-strut DES options represent an effective choice in bifurcation lesions. Postdilation and provisional stenting are associated with a reduced risk of TLR. FKB should be recommended in 2-stent techniques.

Balancing ischaemic and bleeding risks in high-risk populations undergoing percutaneous coronary interventions has become an everyday dilemma for clinicians. It is particularly difficult to make decisions concerning combinations and duration of antiplatelet regimens in women given the poor representation of women in trials that have shaped current practice. Several contemporary landmark trials have recently been presented at the American College of Cardiology. The trials included the Harmonising Optimal Strategy for Treatment of coronary artery diseases-EXtended Antiplatelet Monotherapy, Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention and the TicAgrelor versus CLOpidogrel in Stabilised Patients With Acute Myocardial Infarction. In this article, we summarise the main findings of these trials and include the The Polymer-free Drug-Coated Coronary Stents in Patients at High Bleeding Risk (LEADERS FREE) in search for evidence based best practices for women patients. Although some of these trials had prespecified a subanalysis of sex differences, women constituted only 17%-30% of participants making sex-specific analyses challenging. Data suggest that women benefit from de-escalation to both ticagrelor and clopidogrel monotherapy. However, given the increased bleeding risks observed in women further randomised controlled trials are necessary to determine the most appropriate combination and duration of dual antiplatelet therapy as well as maintenance single antiplatelet therapy.

Ellis grade III coronary artery perforations (G3-CAP) remain a life-threatening complication of percutaneous coronary intervention (PCI), with high morbidity and mortality and lack of consensus regarding optimal treatment strategies. We reviewed all PCIs performed in 10 European centers from 1993 to 2019 recording all G3-CAP along with management strategies, in-hospital and long-term outcome according to Device-related perforations (DP) and Guidewire-related perforations (WP). Among 106,592 PCI (including 7,773 chronic total occlusions), G3-CAP occurred in 311 patients (0.29%). DP occurred in 194 cases (62.4%), more commonly in proximal segments (73.2%) and frequently secondary to balloon dilatation (66.0%). WP arose in 117 patients (37.6%) with chronic total occlusions guidewires involved in 61.3% of cases. Overall sealing success rate was 90.7% and usually required multiple maneuvers (80.4%). The most commonly adopted strategies to obtain hemostasis were prolonged balloon inflation (73.2%) with covered stent implantation (64.4%) in the DP group, and prolonged balloon inflation (53.8%) with coil embolization (41%) in the WP group. Procedural or in-hospital events arose in 38.2% of cases: mortality was higher after DP (7.2% vs 2.6%, pâ¯=â¯0.05) and acute stent thrombosis 3-fold higher (3.1% vs 0.9%, pâ¯=â¯0.19). At clinical follow-up, median 2 years, a major cardiovascular event occurred in one-third of cases (all-cause mortality 8.2% and 7.1% respectively, without differences between groups). In conclusion, although rare and despite improved rates of adequate perforation sealing G3-CAP cause significant adverse events. DP and WP result in different patterns of G3-CAP and management strategies should be based on this classification.

BACKGROUND: The clinical impact of stent strut thickness in coronary bifurcation lesions in small vessels has not been assessed in a real-world population. METHODS: All 506 patients enrolled in the RAIN study, undergoing PCI in a vessel with a diameter 2.5âmm or less were retrospectively evaluated and divided into two groups according to stent strut thickness: 74âµm (nâ=â206) versus 81âµm (nâ=â300); 87.1% of the lesions involved bifurcations. TLF [defined as a composite of myocardial infarction (MI) and target lesion revascularization (TLR)] was the primary endpoint, with MACE (a composite of death, MI and TLR), its components and stent thrombosis the secondary endpoint. RESULTS: After 16 (14-18) months, a lower incidence of TLF (4.3 vs. 9.8%, Pâ=â0.026) and ST (1.0 vs. 3.0%, Pâ=â0.042) was seen in the 74âµm group, whereas MACE occurred in 60 of 506 patients, with no statistical difference between the two groups (9.7 vs. 13.3%, Pâ=â0.070). At multivariate analysis, chronic renal failure increased the risk of TLF while thinner strut was an independent protective factor (hazard ratio 0.51, CI 0.17-0.85, Pâ=â0.005). CONCLUSION: In this real-world population, patients being treated for small vessels lesions with thinner strut stents had lower rates of TLF, MI and ST.

OBJECTIVE: Outcomes of complex percutaneous coronary interventions (PCIs) in older patients are still debated. The aim of the study was to evaluate clinical outcomes of Octogenarian patients treated with ultrathinstents on left main or on coronary bifurcations, compared with younger patients. METHODS: All consecutive patients presenting a critical lesion of an unprotected left main (ULM) or a bifurcation and treated with very thin stents were included in the RAIN (veRy thin stents for patients with left mAIn or bifurcatioN in real life) registry and divided into octogenarians group (OG, 551 patients) and nonoctogenarians (NOGs, 2,453 patients). Major adverse cardiovascular event (MACE), a composite end point of all-cause death, nonfatal myocardial infarction (MI), target lesion revascularization (TLR), and stent thrombosis (ST), was the primary endpoint, while MACE components, cardiovascular (CV) death, and target vessel revascularization (TVR) were the secondary ones. RESULTS: Indication for PCI was acute coronary syndrome in 64.7% of the OG versus 53.1% of the NOG. Severe calcifications and a diffuse disease were significantly more in OG. After a follow-up of 15.2 ± 10.3 months, MACEs were higher in the OG than in the NOG patients (OG 19.1% vs. NOG 11.2%, p < .001), along with MI (OG 6% vs. NOG 3.4%, p = .002) and all-cause death (OG 14% vs. NOG 4.3%, p < .001). In contrast, no significant difference was detected in CV-death (OG 5.1% vs. NOG 4%, p = .871), TVR/TLR, or ST. At multivariate analysis, age was not an independent predictor of MACE (OR 1.02 CI 95% 0.76-1.38), while it was for all-cause death, along with diabetes, GFR < 60 ml/min, and ULM disease. DISCUSSION: Midterm outcomes of complex PCI in OG are similar to those of younger patients. However, due to the higher non-CV death rate, accurate patient selection is mandatory.

BACKGROUND: The PARIS risk score (PARIS-rs) and percutaneous coronary intervention complexity (PCI-c) predict clinical and procedural residual ischemic risk following PCI. Their accuracy in patients undergoing unprotected left main (ULM) or bifurcation PCI has not been assessed. METHODS: The predictive performances of the PARIS-rs (categorized as low, intermediate, and high) and PCI-c (according to guideline-endorsed criteria) were evaluated in 3,002 patients undergoing ULM/bifurcation PCI with very thin strut stents. RESULTS: After 16 (12-22) months, increasing PARIS-rs (8.8% vs. 14.1% vs. 27.4%, p < .001) and PCI-c (15.2% vs. 11%, p = .025) were associated with higher rates of major adverse cardiac events ([MACE], a composite of death, myocardial infarction [MI], and target vessel revascularization), driven by MI/death for PARIS-rs and target lesion revascularization/stent thrombosis for PCI-c (area under the curves for MACE: PARIS-rs 0.60 vs. PCI-c 0.52, p-for-difference < .001). PCI-c accuracy for MACE was higher in low-clinical-risk patients; while PARIS-rs was more accurate in low-procedural-risk patients. ≥12-month dual antiplatelet therapy (DAPT) was associated with a lower MACE rate in high PARIS-rs patients, (adjusted-hazard ratio 0.42 [95% CI: 0.22-0.83], p = .012), with no benefit in low to intermediate PARIS-rs patients. No incremental benefit with longer DAPT was observed in complex PCI. CONCLUSIONS: In the setting of ULM/bifurcation PCI, the residual ischemic risk is better predicted by a clinical risk estimator than by PCI complexity, which rather appears to reflect stent/procedure-related events. Careful procedural risk estimation is warranted in patients at low clinical risk, where PCI complexity may substantially contribute to the overall residual ischemic risk.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a rare condition, mainly affecting young women. Cases in male patients are rare, especially with recurrence. CASE SUMMARY: A 59-year-old male non-elite athlete presented as an ST-elevation myocardial infarction following a 5-km run. Urgent coronary angiogram was normal, but cardiac magnetic resonance showed a myocardial infarction. Four years later, he experienced similar chest pain with no ST-elevation on electrocardiogram and a mild troponin rise. Urgent coronary angiogram was initially thought normal but subsequent close inspection confirmed a Type 2b SCAD. Cardiac magnetic resonance showed a small additional myocardial infarction contained within an area of acute myocardial oedema. DISCUSSION: Spontaneous coronary artery dissection is more common in young women compared to men and recurrent dissection has been rarely reported in the literature. Cohort studies have shown the rate of recurrent dissection to be 13-16%, but most of the patients in these cohorts are female. Poor data exists on the best treatment of SCAD in men, but given the presence of intramural thrombus, dual antiplatelet therapy was discontinued on the presumption that it may exacerbate an intramural bleeding process.
RESUMO
INTRODUCTION: There is a lack of data on clinical outcomes of percutaneous coronary intervention (PCI) with ultrathin stents on unprotected left main (ULM) coronary artery comparing women and men. METHODS: All patients treated with ULM-PCI with ultrathin stents (struts ≤81 µm) enrolled in the RAIN-CARDIOGROUP VII study were analyzed according to a sex-assessment evaluation. Major adverse cardiovascular event (MACE, a composite of all-cause death, myocardial infarction, target-lesion revascularization [TLR], and stent thrombosis) was the primary endpoint, whereas single components of MACE were the secondary endpoints. RESULTS: Out of a cohort of 793 patients, a total of 172 women (21.7%) and 621 men (78.3%) were included. Compared with men, women were older and less frequently smokers, had more frequently a history of previous PCI, and presented more frequently with an acute coronary syndrome. Among women, ostial lesions were more prevalent and mean stent diameter was lower compared with men. After 13.4 months (range, 8.4-21.6 months), 32 women (18.6%) and 106 men (17.1%) experienced MACE (P=.64). Censoring follow-up data at 3 years, no differences were observed in MACE (16.9 vs 14.7 per 100â¢patient-years; log-rank P=.61) and their single components between women and men. At multivariate analysis, chronic kidney disease (hazard ratio [HR], 1.91: 95% confidence interval [CI], 1.23 to -2.95; P<.01) and acute coronary syndrome presentation (HR, 1.84; 95% CI, 1.22-2.77; P=.01) were independent predictors of MACE overall. Larger stent size (HR, 0.65; 95% CI, 0.48-0.89; P<.01) and longer dual-antiplatelet therapy duration (HR, 0.95; 95% CI, 0.90-0.99; P=.03) were associated with a reduced risk of MACE during the subsequent follow-up. CONCLUSION: Ultrathin stents offer low rates of MACE and TLR in the overall population without significant differences between sexes.

BACKGROUND: There are limited data regarding the impact of bioresorbable polymer drug eluting stent (BP-DES) compared to durable polymer drug eluting stent (DP-DES) in patients treated with percutaneous coronary intervention using ultrathin stents in left main or bifurcations. METHODS: In the RAIN registry (ClinicalTrials NCT03544294, june 2018 retrospectively registered) patients with a ULM or bifurcation stenosis treated with PCI using ultrathin stents (struts thinner than 81 µm) were enrolled. The primary endpoint was the rate of target lesion revascularization (TLR); major adverse cardiovascular events (MACE, a composite of all-cause death, myocardial infarction, TLR and stent thrombosis) and its components, along with target vessel revascularization (TVR) were the secondary ones. A propensity score with matching analysis to compare patients treated with BP-DES versus DP-DES was also assessed. RESULTS: From 3001 enrolled patients, after propensity score analysis 1400 patients (700 for each group) were selected. Among them, 352 had ULM disease and 1048 had non-LM bifurcations. At 16 months (12-22), rates of TLR (3.7% vs 2.9%, p = 0.22) and MACE were similar (12.3% vs. 11.6%, p = 0.74) as well as for the other endpoints. Sensitivity analysis of outcomes after a two-stents strategy, showed better outcome in term of MACE (20.4% vs 10%, p = 0.03) and TVR (12% vs 4.6%, p = 0.05) and a trend towards lower TLR in patients treated with BP-DES. CONCLUSION: In patients with bifurcations or ULM treated with ultrathin stents BP-DES seems to perform similarly to DP-DES: the trends toward improved clinical outcomes in patients treated with the BP-DES might potentially be of value for speculating the stent choice in selected high-risk subgroups of patients at increased risk of ischemic events.
