RESUMO
BACKGROUND: Guide catheter extensions (GCEs) increase support and facilitate equipment delivery, but aggressive instrumentation may be associated with a higher risk of complications. AIM: Our aim was to assess the impact of GCEs on procedural success and complications in patients submitted to chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We analyzed data from the multicenter LATAM CTO Registry. Procedural success was defined as <30% residual stenosis and TIMI 3 distal flow. Major adverse cardiac and cerebrovascular events (MACCE) was defined as the composite of all-cause death, myocardial infarction, target vessel revascularization, and stroke. Propensity score matching (PSM) was used to compare outcomes with and without GCE use. RESULTS: From August 2010 to August 2021, 3049 patients were included. GCEs were used in 438 patients (14.5%). In unadjusted analysis, patients in the GCE group were older and had more comorbidities. The median J-CTO score and its components were higher in the GCE group. After PSM, procedural success was higher with GCE use (87.7% vs. 80.5%, p = 0.007). The incidence of coronary perforation (odds ratio [OR]: 1.46, 95% confidence interval [CI]: 0.78-2.71, p = 0.230), bleeding (OR: 1.99, 95% CI: 0.41-2.41, p = 0.986), in-hospital death (OR: 1.39, 95% CI: 0.54-3.62, p = 0.495) and MACCE (OR: 1.07, 95% CI: 0.52-2.19, p = 0.850) were similar in both groups. CONCLUSION: In a contemporary, multicenter cohort of patients undergoing CTO PCI, GCEs were used in older patients, with more comorbidities and complex anatomy. After PSM, GCE use was associated with higher procedural success, and similar incidence of adverse outcomes.

OBJECTIVE: Type D personality, a joint tendency toward negative affectivity and social inhibition, has been linked to adverse events in patients with heart disease, although with inconsistent findings. Here, we apply an individual patient-data meta-analysis to data from 19 prospective cohort studies ( N = 11,151) to investigate the prediction of adverse outcomes by type D personality in patients with acquired cardiovascular disease. METHOD: For each outcome (all-cause mortality, cardiac mortality, myocardial infarction, coronary artery bypass grafting, percutaneous coronary intervention, major adverse cardiac event, any adverse event), we estimated type D's prognostic influence and the moderation by age, sex, and disease type. RESULTS: In patients with cardiovascular disease, evidence for a type D effect in terms of the Bayes factor (BF) was strong for major adverse cardiac event (BF = 42.5; odds ratio [OR] = 1.14) and any adverse event (BF = 129.4; OR = 1.15). Evidence for the null hypothesis was found for all-cause mortality (BF = 45.9; OR = 1.03), cardiac mortality (BF = 23.7; OR = 0.99), and myocardial infarction (BF = 16.9; OR = 1.12), suggesting that type D had no effect on these outcomes. This evidence was similar in the subset of patients with coronary artery disease (CAD), but inconclusive for patients with heart failure (HF). Positive effects were found for negative affectivity on cardiac and all-cause mortality, with the latter being more pronounced in male than female patients. CONCLUSION: Across 19 prospective cohort studies, type D predicts adverse events in patients with CAD, whereas evidence in patients with HF was inconclusive. In both patients with CAD and HF, we found evidence for a null effect of type D on cardiac and all-cause mortality.

OBJECTIVE: Anger may cause adverse cardiovascular responses, but the effects of anger management on clinical cardiovascular outcomes are insufficiently understood. We sought to assess the influence of anger management through a cognitive behavioral intervention on endothelial function in patients with a recent myocardial infarction (MI). METHODS: Patients with ST-elevation MI and a low anger control score were enrolled during hospitalization in a randomized, parallel, controlled clinical trial. Intervention was anger management with cognitive behavioral techniques implemented by a psychologist in two individual monthly sessions. The primary end point was the between-group difference in the variation of flow-mediated dilation (FMD) in the brachial artery from baseline to the 3-month follow-up. The second end point comprised major cardiovascular events at 24-month follow-up. RESULTS: A total of 43 patients (age = 56 [9] years; 23.3% women) were randomized to the intervention group and 47 patients (age = 58 [10] years; 19.1% women) to the control group. Baseline clinical characteristics were not statistically different between groups. Both groups showed a significant improvement in anger control from baseline to end point; however, the difference in intergroup variation was not statistically significant. The difference in FMD variation from baseline to the 3-month follow-up was significantly higher in the intervention group. The partial η2 was 0.057 (p = .024), indicating a medium effect size. There was no difference between groups regarding major cardiovascular events. CONCLUSIONS: Anger management by cognitive behavioral techniques may improve endothelial function in post-MI patients with low anger control, but it remains unclear via which mechanism these effects occurred. Further studies with larger numbers of patients, assessments of changes in anger, improved comparability of preintervention FMD, and longer follow-up are warranted.Trial Registration:ClinicalTrials.gov identifier: NCT02868216.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is projected to become the third cause of mortality worldwide. COPD shares several pathophysiological mechanisms with cardiovascular disease, especially atherosclerosis. However, no definite answers are available on the prognostic role of COPD in the setting of ST elevation myocardial infarction (STEMI), especially during COVID-19 pandemic, among patients undergoing primary angioplasty, that is therefore the aim of the current study. METHODS: In the ISACS-STEMI COVID-19 registry we included retrospectively patients with STEMI treated with primary percutaneous coronary intervention (PCI) between March and June of 2019 and 2020 from 109 high-volume primary PCI centers in 4 continents. RESULTS: A total of 15,686 patients were included in this analysis. Of them, 810 (5.2%) subjects had a COPD diagnosis. They were more often elderly and with a more pronounced cardiovascular risk profile. No preminent procedural dissimilarities were noticed except for a lower proportion of dual antiplatelet therapy at discharge among COPD patients (98.9% vs. 98.1%, P = 0.038). With regards to short-term fatal outcomes, both in-hospital and 30-days mortality occurred more frequently among COPD patients, similarly in pre-COVID-19 and COVID-19 era. However, after adjustment for main baseline differences, COPD did not result as independent predictor for in-hospital death (adjusted OR [95% CI] = 0.913[0.658-1.266], P = 0.585) nor for 30-days mortality (adjusted OR [95% CI] = 0.850 [0.620-1.164], P = 0.310). No significant differences were detected in terms of SARS-CoV-2 positivity between the two groups. CONCLUSION: This is one of the largest studies investigating characteristics and outcome of COPD patients with STEMI undergoing primary angioplasty, especially during COVID pandemic. COPD was associated with significantly higher rates of in-hospital and 30-days mortality. However, this association disappeared after adjustment for baseline characteristics. Furthermore, COPD did not significantly affect SARS-CoV-2 positivity. TRIAL REGISTRATION NUMBER: NCT04412655 (2nd June 2020).

OBJECTIVES: To evaluate the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in patients with and without prior coronary artery bypass graft (CABG) surgery. BACKGROUND: Data on the outcomes of CTO PCI in patients with versus without CABG remains limited and with scarce representation from developing regions like Latin America. METHODS: We evaluated patients undergoing CTO PCI in 42 centers participating in the LATAM CTO registry between 2008 and 2020. Statistical analyses were stratified according to CABG status. The outcomes of interest were technical and procedural success and in-hospital major adverse cardiac and cerebrovascular events (MACCE). RESULTS: A total of 1662 patients were included (n = 1411 [84.9%] no-CABG and n = 251 [15.1%] prior-CABG). Compared with no-CABG, those with prior-CABG were older (67 ± 11 vs. 64 ± 11 years; p < 0.001), had more comorbidities and lower left ventricular ejection fraction (52.8 ± 12.8% vs. 54.4 ± 11.7%; p = 0.042). Anatomic complexity was higher in the prior-CABG group (J-CTO score 2.46 ± 1.19 vs. 2.10 ± 1.22; p < 0.001; PROGRESS CTO score 1.28 ± 0.89 vs. 0.91 ± 0.85; p < 0.001). Absence of CABG was associated with lower risk of technical and procedural failure (OR: 0.60, 95% CI: 0.43-0.85 and OR: 0.58, 95% CI: 0.40-0.83, respectively). No significant differences in the incidence of in-hospital MACCE (3.8% no-CABG vs. 4.4% prior-CABG; p = 0.766) were observed between groups. CONCLUSION: In a contemporary multicenter CTO-PCI registry from Latin America, prior-CABG patients had more comorbidities, higher anatomical complexity, lower success, and similar in-hospital adverse event rates compared with no-CABG patients.

The consumption of nuts and extra-virgin olive oil has been associated with suppression of inflammatory pathways that contribute to atherosclerosis, but its role on the modulation of the inflammatory profile in patients with established coronary artery disease (CAD) is unclear. The aim of this study was to evaluate the effects of adding pecan nuts or extra-virgin olive oil to a healthy diet on inflammatory markers in patients with stable CAD. In this randomised clinical trial, 204 patients were enrolled to three study groups: sixty seven to control group (CG: healthy diet), sixty eight to pecan nuts group (PNG: 30 g/d of pecans + healthy diet) and sixty nine to extra-virgin olive oil group (OOG: 30 ml/d of extra-virgin olive oil + healthy diet). High-sensitivity C-reactive protein (hs-CRP, in mg/l), fibrinogen (mg/dl), IL 2, 4, 6, 10 (pg/ml) and interferon-γ (IFN-γ, in pg/ml), IL-6/IL-10, IL-2/IL-4 and IFN-/γIL-4 ratios were evaluated at baseline and after the follow-up (12 weeks). As main results, after adjustment for sex, statin used and relative body weight variation, there were no differences between groups regarding inflammatory markers at the end of the study. IL-6 levels (primary outcome) were reduced in 12 weeks when compared with baseline in all study groups (CG: difference: -0·593 (se = 0·159) pg/dL; PNG: difference: -0·335 (se = 0·143) pg/dl; OOG: IL-6 difference: -0·325 (se = 0·143) pg/dl). In conclusion, there was no significant effect of including pecan nuts or extra virgin olive oil to a healthy diet on inflammatory markers in individuals with CAD.

OBJECTIVES: To inform about contemporary PCI practice of in-stent (IS) chronic total occlusions (CTO) from a large international registry in Latin America. BACKGROUND: IS-CTO represent a distinctive challenge for PCI, but literature is limited and restricted to high-resource regions of the world. METHODS: Patients undergoing CTO PCI enrolled in the LATAM CTO registry from 42 centers in eight countries were included. We analyzed demographics, angiographic, procedure technique, success and postprocedural outcomes between IS-CTO and non-IS-CTO PCI. RESULTS: From 1,565 patients IS-CTO was present in 181 patients (11.5%). IS-CTO patients had higher prevalence of diabetes and hypertension than patients without IS-CTO. IS-CTOs had less calcification (32.5 vs. 46.7%, p < .001), lower prevalence of a proximal branch (36.3 vs. 50.1%, p < .001), more likely to be ostial (24.4 vs. 18.1%, p = .042), were longer (28.5 vs. 25.2 mm, p = .062), and had less interventional collaterals (49.1 vs. 57.3%, p = .038) compared with non-IS-CTO. CTO complexity scores were similar between both groups. There was no statistically significant difference in the initial or successful strategy between IS-CTO and non-IS-CTO PCI. Technical success rates remained high in IS-CTO (86.7%) and non-IS-CTO (83.1%, p = .230). There was no independent association between IS-CTO and technical success in multivariable analysis. There were no differences between IS-CTO and non-IS-CTO groups for in-hospital clinical outcomes. CONCLUSION: In a contemporary, multicenter, and international registry from Latin America, IS-CTO PCI is frequent and has comparable technical success and safety profile compared to non-IS-CTO PCI.

OBJECTIVES: To report clinical, angiographic characteristics, outcomes, and predictors of unsuccessful procedures in patients who underwent chronic total occlusion (CTO) percutaneous coronary interventions (PCI) in Latin America. BACKGROUND: CTO PCI has been increasingly performed worldwide, but there is a lack of information in this region. METHODS: An international multicenter registry was developed to collect data on CTO PCI performed in centers in Latin America. Patient, angiographic, procedural and outcome data were evaluated. Predictors of unsuccessful procedures were assessed by multivariable analysis. RESULTS: We have included data related to 1,040 CTO PCIs performed in seven countries in Latin America (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, and Puerto Rico). The mean age was 64 ± 10 years, and CTO PCI was performed mainly for angina control (81%) or treatment of a large ischemic area (30%). Overall technical success rate was 82.5%, and it was achieved with antegrade wire escalation in 81%, antegrade dissection/re-entry in 8% and with retrograde techniques in 11% of the successful procedures. Multivariable analysis identified moderate/severe calcification, a blunt proximal cap and a previous attempt as independent predictors of unsuccessful procedures. In-hospital major adverse cardiovascular events (MACE) occurred in 3.1% of the cases, death in 1% and cardiac tamponade in 0.9% CONCLUSIONS: CTO PCI in Latin America has been performed mainly for ischemia relief. Procedures were associated with a success rate above 80% and low incidence of MACE. Predictors of unsuccessful procedures were similar to those previously reported in the literature.

BACKGROUND: Contemporary studies assessing the frequency, characteristics, and outcomes of serious infections (SIs) in patients presenting a ST-elevation myocardial infarction are scarce. METHODS: Prospective cohort of consecutive patients undergoing primary percutaneous coronary intervention (pPCI). Serious infection was defined as the presence of infection that prolonged hospitalization. Community-acquired infection (CAI) was defined by SI diagnosed in the first 72 hours of hospitalization, whereas hospital-acquired infections (HAI) were those diagnosed after 72 hours of hospital admission. RESULTS: From December 2009 to November 2012, 1,486 patients were included in the analysis. Serious infection was present in 58 (3.9%) individuals; 30 (2%) patients had CAI and 28 (1.9%) patients had HAI. Respiratory tract infection was responsible for 82% of the SI. Patients with SI were older, had more comorbidities, and had worse angiographic results of the pPCI procedure when compared with those without SIs. After multivariable adjustment, SI was associated with an approximately 10-fold risk of 30-day death. Patients with CAI had more often a history of smoking, Killip III/IV on hospital admission, worse pPCI, and angiographic results than did patients with HAI. However, no differences were seen in 30-day major cardiovascular outcomes between patients with CAI and HAI. CONCLUSION: In a contemporary cohort of unselected ST-elevation myocardial infarction patients representative of the daily practice, SI was uncommon but associated with worse pPCI results and high risk of mortality. The occurrences of CAI or HAI were similar, but CAI patients presented distinctly worse angiographic outcomes than did patients with HAI.

BACKGROUND: Although diabetes mellitus (DM) is a predictor of poor outcomes in patients with ST-segment elevation myocardial infarction (STEMI), few studies have analyzed the impact of DM on the constituency of coronary thrombi. OBJECTIVES: Comparing morphologic and histopathologic aspects of coronary thrombi in STEMI patients with and without DM who underwent primary percutaneous coronary intervention. METHODS: All consecutive patients with STEMI admitted to our institution between April 2010 and December 2012 (n = 1,548) were considered for inclusion. Thrombus material was obtained by aspiration thrombectomy; morphologic and histopathologic aspects were assessed by 3 independent pathologists blinded to clinical characteristics and outcomes. Patients with DM were compared with those without DM. A sensitivity analysis was performed using a propensity score. RESULTS: During the study period, coronary thrombi material from 259 patients was obtained, of whom 19% (n = 49) had diabetes. Diabetic patients were older (P = .10), had a higher frequency of hypertension (P < .01) and dyslipidemia (P = .03), and had a trend to a longer time from the onset of chest pain to hospital arrival (P = .08). The number of retrieved fragments, the size of the thrombi and its composition (leukocytes, fibrin, and erythrocytes percent), and thrombus age and color were similar between patients with or without DM. There were also no statistically significant differences in thrombus constituency of the propensity score-matched patients (n = 92). CONCLUSIONS: In this study, morphologic and histopathologic constituency of coronary thrombi in the setting of a ST-elevation myocardial infarction was not significantly different between patients with or without DM. This finding was intriguing and deserves further investigation.

BACKGROUND: Coronary drug-eluting stents (DES) built with either durable (DP) or biodegradable (BP) polymeric coatings have been largely tested and are extensively available for routine use. However, their comparative performance remains an open question, particularly in more complex subsets of patients. AIMS: We evaluated the outcomes of patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI) using DP-DES versus BP-DES in a large multicenter real-world registry. METHODS: The population comprised patients with STEMI treated with pPCI within 12 h of symptoms onset. Those treated with more than one DES who received different polymer types were excluded. The final cohort for analysis was selected after propensity score matching (PSM), computed to generate similar groups of DP DES versus BP DES. Primary endpoint was the incidence of major adverse cardiac events (MACE), defined as the composite of total death, myocardial infarction and target lesion revascularization at 2 years. RESULTS: From January 2017 to April 2022, a total of 1527 STEMI patients underwent pPCI with a single DES type (587 DP-DES; 940 BP-DES). After PSM, 836 patients (418 patients in the DP-DES and 418 patients in the BP-DES groups), comprised the final study population. Both study groups had a similar baseline profile. Patients treated with BP-DES group had similar rates of MACE (15.3 % vs. 19.4 %, HR 0.69, 95 % CI 0.50-0.94, p = 0.022). Rates of target lesion revascularization was lower in BP DES group (0.7 % vs. 3.8 %, HR 0.17, 95 % CI 0.05-0.51, p = 0.006). CONCLUSION: In a cohort of STEMI patients submitted to pPCI, BP and DP DES had similar rates of the primary outcome. Patients treated with BP DES, however, had a decreased incidence of TLR at after 2-year follow-up.

Chronic total occlusion (CTO) percutaneous coronary intervention is a complex procedure and is associated with considerable risk of complications. Several success and complication scores have been developed; however, data regarding their external validation in other populations such as Latin America are scarce. This study aimed to evaluate the accuracy of the main predictors of success and complications in a broad cohort of procedures in the Latin American (LATAM) CTO registry. From April 2008 to December 2023, 3,706 consecutive procedures listed in the LATAM CTO registry were screened. Of these, 2,835 procedures had sufficient information to analyze the Multicenter CTO Registry in Japan (J-CTO); Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS); Ostial location, Rentrop grade, and Age (ORA); Clinical and Lesion-related Score (CL-score); and EuroCTO Score (CASTLE) success scores. The complication scores were PROGRESS (MACE, mortality, and pericardiocentesis) and Outcomes, Patient health status, and Efficiency iN Chronic Total Occlusion hybrid procedures (OPEN-CTO),OPEN-CLEAN. The J-CTO and CASTLE scores demonstrated the highest areas under the curve (AUC) of 0.718 and 0.703, respectively. The AUC value for the CL-score was 0.685, whereas the PROGRESS score had an AUC of 0.598 and the ORA AUC was 0.545. The level of agreement between scores was low; only 4% of the procedures were classified as difficult or very difficult by all scores and <1% were classified as easy by all 5 scores. Of the complication scores, PROGRESS mortality (AUC 0.651) and PROGRESS MACE (AUC 0.588) showed the best performance, identifying groups with >10% event rate. These results may improve the selection of revascularization techniques, especially for patient demographics that are historically underrepresented in CTO research.

BACKGROUND: The current gold standard of coronary drug-eluting stents (DES) consists of metal alloys with thinner struts and bioresorbable polymers. OBJECTIVES: Our aim was to compare an ultrathin strut, sirolimus-eluting stent (Inspiron®) with other third-generation DES platforms in patients with ST-elevation myocardial infarction (STEMI) submitted to primary percutaneous coronary intervention (PCI). METHODS: We analyzed data from a STEMI multicenter registry from reference centers in the South Region of Brazil. All patients were submitted to primary PCI, either with Inspiron® or other second- or third-generation DES. Propensity score matching (PSM) was computed to generate similar groups (Inspiron® versus other stents) in relation to clinical and procedural characteristics. All hypothesis tests had a two-sided significance level of 0.05. RESULTS: From January 2017 to January 2021, 1711 patients underwent primary PCI, and 1417 patients met our entry criteria (709 patients in the Inspiron® group and 708 patients in the other second- or third-generation DES group). After PSM, the study sample was comprised of 706 patients (353 patients in the Inspiron® group and 353 patients in the other the other second- or third-generation DES group). The rates of target vessel revascularization (OR 0.52, CI 0.21 - 1.34, p = 0.173), stent thrombosis (OR 1.00, CI 0.29 - 3.48, p = 1.000), mortality (HR 0.724, CI 0.41 - 1.27, p = 0.257), and major cardiovascular outcomes (OR 1.170, CI 0.77 - 1.77, p = 0.526) were similar between groups after a median follow-up of 17 months. CONCLUSION: Our findings show that Inspiron® was effective and safe when compared to other second- or third-generation DES in a contemporary cohort of real-world STEMI patients submitted to primary PCI.
FUNDAMENTO: O padrão-ouro atual dos stents farmacológicos (SF) coronários consiste em ligas metálicas com hastes mais finas e polímeros bioabsorvíveis. OBJETIVOS: Nosso objetivo foi comparar um stent eluidor de sirolimus de hastes ultrafinas (Inspiron®) com outras plataformas de SF de terceira geração em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST) submetidos à intervenção coronária percutânea (ICP) primária. MÉTODOS: Analisamos dados de um registro multicêntrico de IAMCSST de centros de referência da Região Sul do Brasil. Todos os pacientes foram submetidos à ICP primária, seja com Inspiron® ou outro SF de segunda ou terceira geração. Foi calculado pareamento por escore de propensão (PEP) para gerar grupos semelhantes (Inspiron® versus outros stents) em relação às características clínicas e do procedimento. Todos os testes de hipótese tiveram um nível de significância bilateral de 0,05. RESULTADOS: De janeiro de 2017 a janeiro de 2021, 1.711 pacientes foram submetidos à ICP primária, e 1.417 pacientes preencheram nossos critérios de inclusão (709 pacientes no grupo Inspiron® e 708 pacientes no grupo dos outros SF de segunda ou terceira geração). Após PEP, a amostra do estudo foi composta por 706 pacientes (353 pacientes no grupo Inspiron® e 353 pacientes no grupo dos demais SF de segunda ou terceira geração). As taxas de revascularização do vaso alvo (odds ratio [OR] 0,52; intervalo de confiança [IC] 0,21 a 1,34; p = 0,173), trombose de stent (OR 1,00; IC 0,29 a 3,48;p = 1,000), mortalidade (hazard ratio 0,724; IC 0,41 a 1,27; p = 0,257) e os desfechos cardiovasculares maiores (OR 1,170; IC 0,77 a 1,77; p = 0,526) foram semelhantes entre os grupos após um acompanhamento mediano de 17 meses. CONCLUSÃO: Nossos achados mostram que o stent Inspiron® foi eficaz e seguro quando comparado a outros SF de segunda ou terceira geração em uma coorte contemporânea do mundo real de pacientes com IAMCSST submetidos à ICP primária.

BACKGROUND: Ultra-thin strut drug-eluting stent (UTS-DES) may improve outcomes after percutaneous coronary intervention (PCI) but have received limited study in chronic total occlusion (CTO) PCI. AIMS: To compare of 1-year incidence of major adverse cardiac events (MACE) between patients who underwent CTO PCI with ultrathin (≤ 75 µm) versus thin (>75 µm) strut DES in the LATAM CTO registry. METHODS: Patients were considered for inclusion only if successful CTO PCI was performed and when only one type of stent strut thickness (ultrathin or thin) was used. A propensity score matching (PSM) was computed to produce similar groups in relation to clinical and procedural characteristics. RESULTS: Between January 2015 and January 2020, 2092 patients underwent CTO PCI, of whom 1466 were included in the present analysis (475 in the ultra-thin and 991 in the thin strut DES). In unadjusted analysis the UTS-DES group had lower rate of MACE (HR: 0.63 95 % CI 0.42 to 0.94, p = 0.04) and repeat revascularizations (HR: 0.50 95 % CI 0.31 to 0.81, p = 0.02) at 1-year follow-up. After adjustment for confounding factors in a Cox regression model there was no difference in 1-year incidence of MACE between groups (HR: 1.15 95 % CI 0.41 to 2.97, p = 0.85). On PSM of 686 patients (343 in each group) the 1-year incidence of MACE (HR 0.68 95 % CI 0.37-1.23; P = 0.22) and individual components of MACE did not differ between groups. CONCLUSIONS: One-year clinical outcomes after CTO PCI were similar with ultrathin and thin strut DES.

BACKGROUND: Several reports have demonstrated the impact of the COVID-19 pandemic on the management and outcome of patients with ST-segment elevation myocardial infarction (STEMI). The aim of the current analysis is to investigate the potential gender difference in the effects of the COVID-19 pandemic on mechanical reperfusion and 30-day mortality for STEMI patients within the ISACS-STEMI COVID-19 Registry. METHODS: This retrospective multicenter registry was performed in high-volume primary percutaneous coronary intervention (PPCI) centers on four continents and included STEMI patients undergoing PPCIs in March-June 2019 and 2020. Patients were divided according to gender. The main outcomes were the incidence and timing of the PPCI, (ischemia time ≥ 12 h and door-to-balloon ≥ 30 min) and in-hospital or 30-day mortality. RESULTS: We included 16683 STEMI patients undergoing PPCIs in 109 centers. In 2020 during the pandemic, there was a significant reduction in PPCIs compared to 2019 (IRR 0.843 (95% CI: 0.825-0.861, p < 0.0001). We did not find a significant gender difference in the effects of the COVID-19 pandemic on the numbers of STEMI patients, which were similarly reduced from 2019 to 2020 in both groups, or in the mortality rates. Compared to prepandemia, 30-day mortality was significantly higher during the pandemic period among female (12.1% vs. 8.7%; adjusted HR [95% CI] = 1.66 [1.31-2.11], p < 0.001) but not male patients (5.8% vs. 6.7%; adjusted HR [95% CI] = 1.14 [0.96-1.34], p = 0.12). CONCLUSIONS: The COVID-19 pandemic had a significant impact on the treatment of patients with STEMI, with a 16% reduction in PPCI procedures similarly observed in both genders. Furthermore, we observed significantly increased in-hospital and 30-day mortality rates during the pandemic only among females. Trial registration number: NCT 04412655.
RESUMO
Coronary artery perforation is one of the most common and feared complications of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We evaluated the utility of the recently presented OPEN-CLEAN (Coronary artery bypass graft, Length of occlusion, Ejection fraction, Age, calcificatioN) perforation score in an independent multicenter CTO PCI dataset. Of the 2,270 patients who underwent CTO PCI at 7 centers, 150 (6.6%) suffered coronary artery perforation. Patients with perforations were older (69 ± 10 vs 65 ± 10, p <0.001), more likely to be women (89% vs 82%, p = 0.010), more likely to have history of previous coronary artery bypass graft (38% vs 20%, p <0.001), and unfavorable angiographic characteristics such as blunt stump (64% vs 42%, p <0.001), proximal cap ambiguity (51% vs 33%, p <0.001), and moderate-severe calcification (57% vs 43%, p = 0.001). Technical success was lower in patients with perforations (69% vs 85%, p <0.001). The area under the receiver operating characteristic curve of the OPEN-CLEAN perforation risk model was 0.74 (95% confidence interval 0.68 to 0.79), with good calibration (Hosmer-Lemeshow p = 0.72). We found that the CTO PCI perforation risk increased with higher OPEN-CLEAN scores: 3.5% (score 0 to 1), 3.1% (score 2), 5.3% (score 3), 7.1% (score 4), 11.5% (score 5), 19.8% (score 6 to 7). In conclusion, given its good performance and ease of preprocedural calculation, the OPEN-CLEAN perforation score appears to be useful for quantifying the perforation risk for patients who underwent CTO PCI.

BACKGROUND: Major advances have been seen in techniques and devices for performing percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs), but there are limited real-world practice data from developing countries. OBJECTIVES: To report clinical and angiographic characteristics, procedural aspects, and clinical outcomes of CTO PCI performed at dedicated centers in Brazil. METHODS: Included patients underwent CTO PCI at centers participating in the LATAM CTO Registry, a Latin American multicenter registry dedicated to prospective collection of these data. Inclusion criteria were procedures performed in Brazil, age 18 years or over, and presence of CTO with PCI attempt. CTO was defined as a 100% lesion in an epicardial coronary artery, known or estimated to have lasted at least 3 months. RESULTS: Data on 1196 CTO PCIs were included. Procedures were performed primarily for angina control (85%) and/or treatment of moderate/severe ischemia (24%). Technical success rate was 84%, being achieved with antegrade wire approaches in 81% of procedures, antegrade dissection and re-entry in 9%, and retrograde approaches in 10%. In-hospital adverse cardiovascular events occurred in 2.3% of cases, with a mortality rate of 0.75%. CONCLUSIONS: CTOs can be treated effectively in Brazil by using PCI, with low complication rates. The scientific and technological development observed in this area in the past decade is reflected in the clinical practice of dedicated Brazilian centers.
FUNDAMENTO: Tem sido observado um grande avanço nas técnicas e nos dispositivos para a realização de intervenções coronárias percutâneas (ICP) em oclusões totais coronarianas crônicas (OTC), mas existem poucos dados da prática do mundo real em países em desenvolvimento. OBJETIVOS: Relatar as características clínicas e angiográficas, os aspectos dos procedimentos e os resultados clínicos da ICP de OTC em centros dedicados a esse procedimento no Brasil. MÉTODOS: Os pacientes incluídos foram submetidos à ICP de OTC em centros participantes do LATAM CTO Registry, um registro multicêntrico latino-americano dedicado à coleta prospectiva desses dados. Os critérios de inclusão foram procedimentos realizados no Brasil, idade acima de 18 anos e presença de OTC com tentativa de ICP. A definição de OTC foi lesão de 100% em uma artéria coronária epicárdica, conhecida ou estimada como tendo pelo menos 3 meses de evolução. RESULTADOS: Foram incluídos dados de 1.196 ICPs de OTC. Os procedimentos foram realizados principalmente para controle da angina (85%) e/ou tratamento de uma grande área isquêmica (24%). A taxa de sucesso técnico foi de 84% e foi alcançada com técnicas de fios anterógrados em 81%, dissecção/reentrada anterógrada em 9% e retrógrada em 10% dos procedimentos. Os eventos cardiovasculares adversos intra-hospitalares ocorreram em 2,3% dos casos, sendo a mortalidade de 0,75%. CONCLUSÕES: As OTC podem ser tratadas no Brasil por intervenção coronária percutânea de forma efetiva e com baixas taxas de complicações. O desenvolvimento científico e tecnológico observado nessa área na última década reflete-se na prática clínica de centros brasileiros dedicados a essa técnica.

BACKGROUND: The constraints in the management of patients with ST-segment elevation myocardial infarction (STEMI) during the COVID-19 pandemic have been suggested to have severely impacted mortality levels. The aim of the current analysis is to evaluate the age-related effects of the COVID-19 pandemic on mechanical reperfusion and 30-day mortality for STEMI within the registry ISACS-STEMI COVID-19. METHODS: This retrospective multicenter registry was performed in high-volume PPCI centers on four continents and included STEMI patients undergoing PPCI in March-June 2019 and 2020. Patients were divided according to age (< or ≥75 years). The main outcomes were the incidence and timing of PPCI, (ischemia time longer than 12 h and door-to-balloon longer than 30 min), and in-hospital or 30-day mortality. RESULTS: We included 16,683 patients undergoing PPCI in 109 centers. In 2020, during the pandemic, there was a significant reduction in PPCI as compared to 2019 (IRR 0.843 (95%-CI: 0.825-0.861, p < 0.0001). We found a significant age-related reduction (7%, p = 0.015), with a larger effect on elderly than on younger patients. Furthermore, we observed significantly higher 30-day mortality during the pandemic period, especially among the elderly (13.6% vs. 17.9%, adjusted HR (95% CI) = 1.55 [1.24-1.93], p < 0.001) as compared to younger patients (4.8% vs. 5.7%; adjusted HR (95% CI) = 1.25 [1.05-1.49], p = 0.013), as a potential consequence of the significantly longer ischemia time observed during the pandemic. CONCLUSIONS: The COVID-19 pandemic had a significant impact on the treatment of patients with STEMI, with a 16% reduction in PPCI procedures, with a larger reduction and a longer delay to treatment among elderly patients, which may have contributed to increase in-hospital and 30-day mortality during the pandemic.
RESUMO
SARS-Cov-2 has been suggested to promote thrombotic complications and higher mortality. The aim of the present study was to evaluate the impact of SARS-CoV-2 positivity on in-hospital outcome and 30-day mortality in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) enrolled in the International Survey on Acute Coronary Syndromes ST-segment elevation Myocardial Infarction (ISACS-STEMI COVID-19 registry. The 109 SARS-CoV-2 positive patients were compared with 2005 SARS-CoV-2 negative patients. Positive patients were older (P = .002), less often active smokers (P = .002), and hypercholesterolemic (P = .006), they presented more often later than 12 h (P = .037), more often to the hub and were more often in cardiogenic shock (P = .02), or requiring rescue percutaneous coronary intervention after failed thrombolysis (P < .0001). Lower postprocedural Thrombolysis in Myocardial Infarction 3 flow (P = .029) and more thrombectomy (P = .046) were observed. SARS-CoV-2 was associated with a significantly higher in-hospital mortality (25.7 vs 7%, adjusted Odds Ratio (OR) [95% Confidence Interval] = 3.2 [1.71-5.99], P < .001) in-hospital definite in-stent thrombosis (6.4 vs 1.1%, adjusted Odds Ratio [95% CI] = 6.26 [2.41-16.25], P < .001) and 30-day mortality (34.4 vs 8.5%, adjusted Hazard Ratio [95% CI] = 2.16 [1.45-3.23], P < .001), confirming that SARS-CoV-2 positivity is associated with impaired reperfusion, with negative prognostic consequences.
