Experience from a regional percutaneous coronary intervention center: Aiming to assess and improve quality of care.

INTRODUCTION AND OBJECTIVES: Ischemic heart disease is the single most common cause of death in Europe. Mortality in patients presenting with ST-elevation myocardial infarction (STEMI) is associated with many factors, one of which is the time delay to treatment. The purpose of this work is to analyze the coronary pathway in our region in terms of timing, taking into consideration the place of first medical contact (FMC). METHODS: Consecutive patients admitted to our center with STEMI to undergo percutaneous coronary intervention (PCI) between 2013 and 2022 were analyzed. Age, gender, and time delays were collected. Analysis was performed with IBM SPSS version 28 for a significance level of 0.05. RESULTS: We found that non-PCI centers had a significantly greater FMC to diagnosis delay and diagnosis to wire delay compared to other places of origin. Only 2.2% of patients met the 10-min FMC to diagnosis target; 44.8% met the target of 90 min from diagnosis to wire in transferred patients, while 40.6% met the 60-min target for patients admitted to a PCI center. Median patient, electrocardiogram (ECG) and logistic delays are 92.0±146.0 min, 19.0±146.0 min and 15.5±46.3 min, respectively. CONCLUSION: A significant difference between state-of-the-art targets and reality was found, depending on the place of FMC, with the worst delays in non-PCI centers. Patient delay, ECG delay, FMC to diagnosis and logistic delay are identified as key areas in which to intervene.

The Effects of Pre-Season and Relationships with Physical, Physiological, Body Composition, and Load Markers: A Case Study Comparing Starters versus Non-Starters from an Elite Female Professional Soccer Team.

Background and Objectives: Research on female soccer players that analyzes playing status is scarce and has previously only examined load monitoring, while other markers, such as physical (i.e., strength, power, and agility), physiological (i.e., maximal oxygen uptake), and body composition (i.e., body fat mass, fat-free mass, body water, and phase angle) markers, warrant further investigation. Thus, the study aims were to (a) compare physical, physiological, body composition, and load markers between starters and non-starters; (b) compare measurements pre- and post-training intervention (five weeks); and (c) analyze any relationships between physical, physiological, body composition, and load markers in an elite female soccer team. Materials and Methods: Fourteen first-team players participated in the study (age 23.29 ± 3.19 years, weight 59.14 ± 6.87 kg, height 1.66 ± 0.08 m). Several physical (n = 15), physiological (n = 1), body composition (n = 11), and load markers (n = 14) were collected. In addition, participants were sub-divided into starters (n = 7) and non-starters (n = 7). Results: No differences were revealed between starters and non-starters in any of the examined variables. Moreover, following the training intervention, a significantly lower value was found for total body water/fat-free mass ratio (p = 0.043; ES = 0.582). In addition, there were several correlations detected between load and physical/physiological markers (n = 28); load and body composition markers (n = 6); physical/physiological and body composition markers (n = 34); and physical and physiological markers (n = 42). Conclusions: In conclusion, only a slight tendency of higher load values for starters than non-starters was observed. In addition, no differences in physical, physiological, and body composition markers were found between starters and non-starters, possibly suggesting that five weeks were not enough to improve such variables. Finally, the present results provide novel information assessing the effects of the pre-season in elite female Portuguese soccer players and contribute to a better understanding of the associations between different types of measurements.

Impact of the COVID-19 pandemic on percutaneous coronary interventions in Portugal.

INTRODUCTION: The COVID-19 pandemic has imposed an unprecedented burden on healthcare systems worldwide, changing the profile of interventional cardiology activity. OBJECTIVES: To quantify and compare the number of percutaneous coronary interventions (PCIs) performed for acute and chronic coronary syndromes during the first COVID-19 outbreak with the corresponding period in previous years. METHODS: Data on PCI from the prospective multicenter Portuguese Registry on Interventional Cardiology (RNCI) were used to analyze changes in PCI for ST-elevation myocardial infarction (STEMI), non-ST-elevation acute coronary syndromes (NSTE-ACS) and chronic coronary syndromes (CCS). The number of PCIs performed during the initial period of the COVID-19 outbreak in Portugal, from March 1 to May 2, 2020, was compared with the mean frequency of PCIs performed during the corresponding period in the previous three years (2017-2019). RESULTS: The total number of PCIs procedures was significantly decreased during the initial COVID-19 outbreak in Portugal (-36%, p<0.001). The reduction in PCI procedures for STEMI, NSTE-ACS and CCS was, respectively, -25% (p<0.019), -20% (p<0.068) and -59% (p<0.001). CONCLUSIONS: Compared with the corresponding period in the previous three years, the number of PCI procedures performed for STEMI and CCS decreased markedly during the first wave of the COVID-19 pandemic in Portugal.

Person-centered care approach to prevention and management of falls among adults and aged in a Brazilian hospital: a best practice implementation project.

OBJECTIVES: The objective is to assess compliance with evidence-based criteria regarding a person-centered care approach to the prevention and management of falls among adults and the elderly in a Brazilian private hospital. METHODS: This project used the JBI audit and feedback method to implement evidence into practice. The JBI Practical Application of Clinical Evidence System and Getting Research into Practice audit tools have been used to promote changes in oncology and medical-surgical wards. The implementation protocol was designed based on the primary barriers and facilitators identified in the baseline audit, along with a training program and changes in the electronic medical records. Nursing documentation available in medical records, interviews with nurses who worked in oncology and medical-surgical wards, and interviews with patients admitted in oncology and medical-surgical wards were used to assess the baseline and follow-up audit compliance rates. RESULTS: The baseline and follow-up audits showed improvement for criteria 3 and 9 (100%) and criteria 6 and 7 (97%), respectively. The compliance for criteria 4 (97.6%), 5 (76.7%), and 8 (18%) showed slight variations from baseline and follow-up audits. Compliance for criteria 1 (76.9%) and 2 (63.3%) decreased in the follow-up audit. CONCLUSION: These findings support that baseline, and follow-up audits allied to a fall training program and changes in the electronic nursing records increase the compliance rates related to evidence-based practice regarding a person-centered care approach to preventing and managing falls. We will implement new strategies according to the best practices to achieve better outcomes.

Prospective application of a bleeding and ischemic risks-adjusted antithrombotic protocol in elderly patients revascularized with everolimus-eluting stents: EPIC05-Sierra75 study.

OBJECTIVES: Elderly patients show a higher incidence of ischemic and bleeding events after percutaneous transluminal coronary intervention (PCI). We sought to investigate outcomes in elderly patients treated with antithrombotic strategy guided by bleeding and ischemic risks after revascularization with last generation everolimus-eluting stent (EES). METHODS: Prospective multicenter registry including patients over 75 years revascularized with EES and antithrombotic therapy guided by clinical presentation, PCI complexity and PRECISE DAPT score. Co-primary safety endpoints were: (1) composite of cardiac death, myocardial infarction and stent thrombosis and; (2) bleeding (BARC 2-5). Primary efficacy endpoint was target lesion revascularization. A matched group of patients revascularized with current drug-eluting stents and no such tailored antithrombotic therapy was used as control. RESULTS: Finally, 1064 patients were included in SIERRA-75 cohort, 80.8 ± 4.2 years, 36.6% women, 71% acute coronary syndromes (ACS) and 53.6% complex PCI. Co-primary safety endpoint of major adverse cardiovascular events was met in 6.2%, co-primary safety endpoint of bleeding in 7.8% and primary efficacy endpoint of TKLR in 1.5%. The multivariable adjusted model showed no significant association of the prescribed short/long dual antiplatelet therapy (DAPT) durations with any endpoint suggesting a well tailored therapy. No stent thrombosis reported in the subgroup with 1-3 months DAPT duration. As compared to control group, bleeding BARC 2-5 was significantly lower in SIERRA-75 group (7.4% vs. 10.2%, P = 0.04) as well as the net safety-efficacy endpoint (14.3% vs. 18.5%, P = 0.02). CONCLUSIONS: In elderly population, the application of this risks-adjusted antithrombotic protocol after revascularization with last generation EES seems to be associated with an improved prognosis in terms of ischemic and bleeding outcomes.

In-Season Microcycle Quantification of Professional Women Soccer Players-External, Internal and Wellness Measures.

Although data currently exists pertaining to the intensity in the women's football match, the knowledge about training is still scarce. Therefore, the aim of this study was to quantify external (locomotor activity) and internal (psychophysiological) intensities, as well as the wellness profile of the typical microcycle from professional female soccer players during the 2019/20 in-season. Ten players (24.6 ± 2.3 years) from an elite Portuguese women soccer team participated in this study. All variables were collected in 87 training session and 15 matches for analysis from the 2019−2020 in-season. Global positioning variables such total distance, high-speed running, acceleration, deceleration and player load were recorded as intensity while Rated Perceived Exertion (RPE) and session-RPE were recorded as internal measures. The Hooper Index (HI) was collected as a wellness parameter. The results showed that internal and external intensity measures were greater in matches compared to trainings during the week (match day minus [MD-], MD-5, MD-4, MD-2), p < 0.05 with very large effect size (ES). In the same line, higher internal and external intensity values were found in the beginning of the week while the lowest values were found in MD-2 (p < 0.05, with very large ES). Regarding wellness, there was no significant differences in the HI parameters between the training days and match days (p > 0.05). This study confirmed the highest intensity values during MD and the lowest on the training session before the MD (MD-2). Moreover, higher training intensities were found in the beginning of the training week sessions which were then reduced when the MD came close. Wellness parameters showed no variation when compared to intensity measures. This study confirmed the hypothesis regarding internal and external intensity but not regarding wellness.

In-Season Internal Load and Wellness Variations in Professional Women Soccer Players: Comparisons between Playing Positions and Status.

The internal intensity monitoring in soccer has been used more in recent years in men's football; however, in women's soccer, the existing literature is still scarce. The aims of this study were threefold: (a) to describe the weekly variations of training monotony, training strain and acute: chronic workload ratio through session Rated Perceived Exertion (s-RPE); (b) to describe weekly variations of Hooper Index [stress, fatigue, Delayed Onset Muscle Soreness (DOMS) and sleep]; and (c) to compare those variations between playing positions and player status. Nineteen players (24.1 ± 2.7 years) from a Portuguese BPI League professional team participated in this study. All variables were collected in a 10-week in-season period with three training sessions and one match per week during the 2019/20 season. Considering the overall team, the results showed that there were some associations between Hooper Index categories and s-RPE like stress or fatigue (0.693, p < 0.01), stress or DOMS (0.593, p < 0.01), stress or s-RPE (-0.516, p < 0.05) and fatigue or DOMS (0.688, p < 0.01). There were no differences between all parameters in playing positions or player status. In conclusion, the study revealed that higher levels of fatigue and DOMS occur concurrently with better nights of sleep. Moreover, any in-season variations concerning internal load and perceived wellness seems independent of position or status in outfield players. The data also showed that the higher the players' reported stress, the lower the observed s-RPE, thus possibly indicating a mutual interference of experienced stress levels on the assimilation of training intensity by elite women soccer players.

In-Season Body Composition Effects in Professional Women Soccer Players.

This study aimed to analyze anthropometric and body composition effects in professional soccer women players across the early and mid-competitive 2019/20 season. Seventeen players (age, height, body mass, and body mass index of 22.7 ± 6.3 years, 167.5 ± 5.6 cm, 60.7 ± 6.6 kg and 21.6 ± 0.2 kg/m2) from a Portuguese BPI League team participated in this study. The participants completed ≥80% of 57 training sessions and 13 matches. They were assessed at three points (before the start of the season (A1), after two months (A2), and after four months (A3)) using the following variables: body fat mass (BFM), soft lean mass (SLM), fat-free mass (FFM), intracellular water (ICW), extracellular water (ECW), total body water (TBW), and phase angle (PhA, 50 Khz), through InBody S10. Nutritional intake was determined through a questionnaire. Repeated measures ANCOVA and effect sizes (ES) were used with p < 0.05. The main results occurred between A1 and A2 for BFM (-21.7%, ES = 1.58), SLM (3.7%, ES = 1.24), FFM (4%, ES = 1.34), ICW (4.2%, ES = 1.41), TBW (3.7%, ES = 1.04). Furthermore, there were significant results between A1 and A3 for FFM (4.8%, ES = 1.51), ICW (5%, ES = 1.68), and PhA (10.4%, ES = 6.64). The results showed that the water parameters improved over time, which led to healthy hydration statuses. The training load structure provided sufficient stimulus for appropriate physical fitness development, without causing negative disturbances in the water compartments.

Creatinine variation improves Zwolle score in selecting low-risk patients after ST-segment elevation myocardial infarction.

BACKGROUND: The Zwolle score is recommended to identify ST-segment elevation myocardial infarction (STEMI) patients with low-risk eligible for early discharge. Our aim was to ascertain if creatinine variation (Δ-sCr) would improve Zwolle score in the decision-making of early discharge after primary percutaneous coronary intervention (PCI). METHODS AND RESULTS: A total of 3296 patients with STEMI that underwent primary PCI were gathered from the Portuguese Registry on Acute Coronary Syndromes. A Modified-Zwolle score, including Δ-sCr, was created and compared with the original Zwolle score. Δ-sCr was also compared between low (Zwolle score ≤3) and non-low-risk patients (Zwolle score >3). The primary endpoint is 30-day mortality and the secondary endpoints are in-hospital mortality and complications. Thirty-day mortality was 1.5% in low-risk patients (35 patients) and 9.2% in non-low-risk patients (92 patients). The Modified-Zwolle score had a better performance than the original Zwolle score in all endpoints: 30-day mortality (area under curve 0.853 versus 0.810, P < 0.001), in-hospital mortality (0.889 versus 0.845, P < 0.001) and complications (0.728 versus 0.719, P = 0.037). Reclassification of patients lead to a net reclassification improvement of 6.8%. Additionally, both original Zwolle score low-risk patients and non-low-risk patients who had a Δ-sCr ≥0.3 mg/dl had higher 30-day mortality (low-risk: 1% versus 6.6%, P < 0.001; non-low-risk 4.4% versus 20.7%, P < 0.001), in-hospital mortality and complications. CONCLUSION: Δ-sCr enhanced the performance of Zwolle score and was associated with higher 30-day mortality, in-hospital mortality and complications in low and non-low-risk patients. This data may assist the selection of low-risk patients who will safely benefit from early discharge after STEMI.

Usefulness of Routine Fractional Flow Reserve for Clinical Management of Coronary Artery Disease in Patients With Diabetes.

Importance: Approximately one-third of patients considered for coronary revascularization have diabetes, which is a major determinant of clinical outcomes, often influencing the choice of the revascularization strategy. The usefulness of fractional flow reserve (FFR) to guide treatment in this population is understudied and has been questioned. Objective: To evaluate the usefulness and rate of major adverse cardiovascular events (MACE) of integrating FFR in management decisions for patients with diabetes who undergo coronary angiography. Design, Setting, and Participants: This cross-sectional study used data from the PRIME-FFR study derived from the merger of the POST-IT study (Portuguese Study on the Evaluation of FFR-Guided Treatment of Coronary Disease [March 2012-November 2013]) and R3F study (French Study of FFR Integrated Multicenter Registries Implementation of FFR in Routine Practice [October 2008-June 2010]), 2 prospective multicenter registries that shared a common design. A population of all-comers for whom angiography disclosed ambiguous lesions was analyzed for rates, patterns, and outcomes associated with management reclassification, including revascularization deferral, in patients with vs without diabetes. Data analysis was performed from June to August 2018. Main Outcomes and Measures: Death from any cause, myocardial infarction, or unplanned revascularization (MACE) at 1 year. Results: Among 1983 patients (1503 [77%] male; mean [SD] age, 65 [10] years), 701 had diabetes, and FFR was performed for 1.4 lesions per patient (58.2% of lesions in the left anterior descending artery; mean [SD] stenosis, 56% [11%]; mean [SD] FFR, 0.81 [0.01]). Reclassification by FFR was high and similar in patients with and without diabetes (41.2% vs 37.5%, P = .13), but reclassification from medical treatment to revascularization was more frequent in the former (142 of 342 [41.5%] vs 230 of 730 [31.5%], P = .001). There was no statistical difference between the 1-year rates of MACE in reclassified (9.7%) and nonreclassified patients (12.0%) (P = .37). Among patients with diabetes, FFR-based deferral identified patients with a lower risk of MACE at 12 months (25 of 296 [8.4%]) compared with those undergoing revascularization (47 of 257 [13.1%]) (P = .04), and the rate was of the same magnitude of the observed rate among deferred patients without diabetes (7.9%, P = .87). Status of insulin treatment had no association with outcomes. Patients (6.6% of the population) in whom FFR was disregarded had the highest MACE rates regardless of diabetes status. Conclusions and Relevance: Routine integration of FFR for the management of coronary artery disease in patients with diabetes may be associated with a high rate of treatment reclassification. Management strategies guided by FFR, including revascularization deferral, may be useful for patients with diabetes.

Resultados inmediatos e impacto funcional y pronóstico tras la recanalización de oclusiones coronarias crónicas. Resultados del Registro Ibérico / Procedural, functional and prognostic outcomes following recanalization of coronary chronic total occlusions. Results of the Iberian Registry

Introducción y objetivos: El impacto de la intervención coronaria percutánea (ICP) sobre oclusiones coronarias crónicas totales (OCT) presenta controversias. Se analizan los resultados agudos y al seguimiento en nuestro entorno. Métodos: Registro prospectivo de ICP sobre OCT en 24 centros durante 2 años. Resultados: Se realizaron 1.000 ICP sobre OCT en 952 pacientes. La mayoría tenía síntomas (81,5%) y cardiopatía isquémica previa (59,2%), y hubo intentos de desobstrucción previos en un 15%. El SYNTAX anatómico fue 19,5 +/- 10,6 y tenía J-score > 2 el 17,3%. El procedimiento fue retrógrado en 92 pacientes (9,2%). La tasa de éxito fue del 74,9%, mayor en aquellos sin ICP previa (el 82,2 frente al 75,2%; p = 0,001), con J-score ≤ 2 (el 80,5 frente al 69,5%; p = 0,002) y con el uso de ecografía intravascular (el 89,9 frente al 76,2%; p = 0,001), que fue predictor independiente del éxito. Por el contrario, lesiones calcificadas, > 20 mm o con muñón proximal romo lo fueron de fracaso. El 7,1% tuvo complicaciones, como perforación (3%), infarto (1,3%) o muerte (0,5%). Al año de seguimiento, el 88,2% mejoró clínicamente en caso de ICP exitosa (frente al 34,8%; p < 0,001). Dicha mejoría se asoció con menor mortalidad. La tasa de mortalidad al año fue del 1,5%. Conclusiones: Los pacientes del Registro Ibérico con OCT tratados con ICP presentan complejidad clínico-anatómica, tasas de éxito y complicaciones similares a los de otros registros nacionales e importante impacto de la recanalización exitosa en la mejoría funcional, que a su vez se asoció con menor mortalidad

Introduction and objectives: There is current controversy regarding the benefits of percutaneous recanalization (PCI) of chronic total coronary occlusions (CTO). Our aim was to determine acute and follow-up outcomes in our setting. Methods: Two-year prospective registry of consecutive patients undergoing PCI of CTO in 24 centers. Results: A total of 1000 PCIs of CTO were performed in 952 patients. Most were symptomatic (81.5%), with chronic ischemic heart disease (59.2%). Previous recanalization attempts had been made in 15%. The mean SYNTAX score was 19.5 +/- 10.6 and J-score was > 2 in 17.3%. A retrograde procedure was performed in 92 patients (9.2%). The success rate was 74.9% and was higher in patients without previous attempts (82.2% vs 75.2%; P = .001), those with a J-score ≤ 2 (80.5% vs 69.5%; P = .002), and in intravascular ultrasound-guided PCI (89.9% vs 76.2%, P = .001), which was an independent predictor of success. In contrast, severe calcification, length > 20mm, and blunt proximal cap were independent predictors of failed recanalization. The rate of procedural complications was 7.1%, including perforation (3%), myocardial infarction (1.3%), and death (0.5%). At 1-year of follow-up, 88.2% of successfully revascularized patients showed clinical improvement (vs 34.8%, P < .001), which was associated with lower mortality. At 1-year of follow-up, the mortality rate was 1.5%. Conclusions: Compared with other national registries, patients in the Iberian registry undergoing PCI of a CTO showed similar complexity, success rate, and complications. Successful recanalization was strongly associated with functional improvement, which was related to lower mortality

Fifteen years of coronary intravascular ultrasound in percutaneous coronary intervention in Portugal. / Quinze anos de ecografia intravascular coronária em intervenção coronária percutânea em Portugal.

INTRODUCTION: Coronary intravascular ultrasound (IVUS) is increasingly important in catheterization laboratories due to its positive prognostic impact. This study aims to characterize the use of IVUS in percutaneous coronary intervention (PCI) in Portugal. METHODS: A retrospective observational study was performed based on the Portuguese Registry on Interventional Cardiology of the Portuguese Society of Cardiology. The clinical and angiographic profiles of patients who underwent PCI between 2002 and 2016, the percentage of IVUS use, and the coronary arteries assessed were characterized. RESULTS: A total of 118 706 PCIs were included, in which IVUS was used in 2266 (1.9%). Over time, use of IVUS changed from none in 2002 to generally increasing use from 2003 (0.1%) to 2016 (2.4%). The age of patients in whom coronary IVUS was used was similar to that of patients in whom IVUS was not used, but in the former group there were fewer male patients, and a higher prevalence of cardiovascular risk factors (hypertension, hypercholesterolemia and diabetes), previous myocardial infarction, previous PCI, multivessel coronary disease, C-type or bifurcated coronary lesions, and in-stent restenosis. IVUS was used in 54.8% of elective PCIs and in 19.15% of PCIs of the left main coronary artery. CONCLUSION: Coronary IVUS has been increasingly used in Portugal since 2003. It is used preferentially in elective PCIs, and in patients with higher cardiovascular risk, with more complex coronary lesions and lesions of the left main coronary artery.

Adjuvant antithrombotic therapy in ST-elevation myocardial infarction: Contemporaneous Portuguese cross-sectional data.

INTRODUCTION: The standard of care for acute ST-elevation myocardial infarction (STEMI) includes the activation of a STEMI care network, the administration of adjuvant medical therapy, and reperfusion through primary percutaneous coronary intervention (PCI). While primary PCI is nowadays the first option for the treatment of patients with STEMI, antithrombotic therapy, including antiplatelet and anticoagulant agents, is the cornerstone of pharmacological treatment to optimize their clinical outcomes. OBJECTIVE: The aim of this study was to describe contemporaneous real-world patterns of use of antithrombotic treatments in Portugal for STEMI patients undergoing primary PCI. METHODS: An observational, retrospective cross-sectional study was performed for the year 2016, based on data from two national registries: the Portuguese Registry on Acute Coronary Syndromes (ProACS) and the Portuguese Registry on Interventional Cardiology (PRIC). Data on oral antiplatelet and procedural intravenous antithrombotic drugs were retrieved. RESULTS: In 2016, the ProACS enrolled 534 STEMI patients treated with primary PCI, while the PRIC registry reported data on 2625 STEMI patients. Of these, 99.6% were treated with aspirin and 75.6% with dual antiplatelet therapy (mostly clopidogrel). GP IIb/IIIa inhibitors (mostly abciximab) were used in 11.6% of cases. Heparins were used in 80% of cases (78% unfractionated heparin [UFH] and 2% low molecular weight heparin). None of the patients included in the registry were treated with cangrelor, prasugrel or bivalirudin. Missing data are one of the main limitations of the registries. CONCLUSIONS: In 2016, according to data from these national registries, almost all patients with STEMI were treated with aspirin and 76% with dual antiplatelet agents, mostly clopidogrel. GP IIb/IIIa inhibitors were used in few patients, and UFH was the most prevalent parenteral anticoagulant drug.

Procedural, Functional and Prognostic Outcomes Following Recanalization of Coronary Chronic Total Occlusions. Results of the Iberian Registry.

Thrombus aspiration in patients with ST-elevation myocardial infarction: results of a national registry of interventional cardiology.

BACKGROUND: We aimed to evaluate the impact of thrombus aspiration (TA) during primary percutaneous coronary intervention (P-PCI) in 'real-world' settings. METHODS: We performed a retrospective study, using data from the National Registry of Interventional Cardiology (RNCI 2006-2012, Portugal) with ST-elevation myocardial infarction (STEMI) patients treated with P-PCI. The primary outcome, in-hospital mortality, was analysed through adjusted odds ratio (aOR) and 95% confidence intervals (95%CI). RESULTS: We assessed data for 9458 STEMI patients that undergone P-PCI (35% treated with TA). The risk of in-hospital mortality with TA (aOR 0.93, 95%CI:0.54-1.60) was not significantly decreased. After matching patients through the propensity score, TA reduced significantly the risk of in-hospital mortality (OR 0.58, 95%CI:0.35-0.98; 3500 patients). CONCLUSIONS: The whole cohort data does not support the routine use of TA in P-PCI, but the results of the propensity-score matched cohort suggests that the use of selective TA may improve the short-term risks of STEMI.

Prader-Willi syndrome: a nest for premature coronary artery disease?

Individuals affected by Prader-Willi syndrome (PWS) may show increased risk for coronary artery disease (CAD), which probably relates, at least, with high burden of cardiovascular risk factors.A 27-year-old man with PWS, obesity, hypertension, diabetes mellitus and dyslipidaemia attended the emergency department with complaints of flu-like condition and chest pain. The ECG revealed a mild ST-segment elevation in inferior leads, followed by positive myocardial necrosis biomarkers. Attending to the high cardiovascular risk profile, ST-segment elevation in inferior territory and wall motion abnormalities, a coronary angiogram was performed. The latter showed a three-vessel CAD, 60% stenosis in midanterior descending artery, total occlusion (100%) of the obtuse marginal artery and 99% stenosis with high thrombi burden in the proximal right coronary artery.The present case report emphasises the plausibility of premature CAD in patients with PWS, a possible underdiagnosed feature of this condition.
