A Prospective, Multicenter, Real-World Registry of Coronary Lithotripsy in Calcified Coronary Arteries: The REPLICA-EPIC18 Study.

BACKGROUND: Intravascular lithotripsy (IVL) has demonstrated effectiveness in the treatment of calcified lesions in selected patients with stable coronary disease. OBJECTIVES: The authors sought to assess the performance of coronary IVL in calcified coronary lesions in a real-life, all comers, setting. METHODS: The REPLICA-EPIC18 study prospectively enrolled consecutive patients treated with IVL in 26 centers in Spain. An independent core laboratory performed the angiographic analysis and event adjudication. The primary effectiveness endpoint assessed procedural success (successful IVL delivery, final diameter stenosis <20%, and absence of in-hospital major adverse cardiovascular events [MACE]). The primary safety endpoint measured freedom from MACE at 30 days. A predefined substudy compared outcomes between acute coronary syndrome (ACS) and chronic coronary syndrome (CCS) patients. RESULTS: A total of 426 patients (456 lesions) were included, 63% of the patients presenting with ACS. IVL delivery was successful in 99% of cases. Before IVL, 49% of lesions were considered undilatable. The primary effectiveness endpoint was achieved in 66% of patients, with similar rates among CCS patients (68%) and ACS patients (65%). Likewise, there were no significant differences in angiographic success after IVL between CCS and ACS patients. The rate of MACE at 30 days (primary safety endpoint) was 3% (1% in CCS and 5% in ACS patients [P = 0.073]). CONCLUSIONS: Coronary IVL proved to be a feasible and safe procedure in a "real-life" setting, effectively facilitating stent implantation in severely calcified lesions. Patients with ACS on admission showed similar angiographic success rates but showed a trend toward higher 30-day MACE compared with patients with CCS.

Ten-year prognostic impact of target versus non-target vessel failure after STEMI. Insight from the EXAMINATION-EXTEND trial.

INTRODUCTION AND OBJECTIVES: After ST-segment myocardial infarction (STEMI), the impact of different adverse events on prognosis remains unknown. We aimed to assess very long-term predictors of patient-oriented composite endpoints (POCE) and investigate whether the occurrence of target vessel failure (TVF) vs a non-TVF event as the first event could potentially influence subsequent outcomes. METHODS: The EXAMINATION-EXTEND trial randomized STEMI patients to receive either an everolimus-eluting stent or a bare-metal stent. The follow-up period was 10 years. Predictors of POCE (a composite of all-cause death, any myocardial infarction, or any revascularization) were evaluated in the overall study population. The patients were stratified based on the type of first event (TVF-first vs non-TVF-first) and were compared in terms of subsequent POCE. TVF was defined as a composite of cardiac death, TV myocardial infarction, or TV revascularization. RESULTS: Out of the 1498 enrolled patients, 529 (35.3%) experienced a POCE during the 10-year follow-up. Independent predictors of POCE were age, diabetes mellitus, previous myocardial infarction, peripheral arterial disease, and multivessel coronary disease. The first event was a TVF in 296 patients and was a non-TVF in 233 patients. No significant differences were observed between TVF-first and non-TVF-first patients in terms of subsequent POCE (21.7% vs 39.3%, time ratio 1.79; 95%CI, 0.87-3.67;P=.12) or its individual components. CONCLUSIONS: At the 10-year follow-up, approximately one-third of STEMI patients had experienced at least 1 POCE. Independent predictors of these events were age, diabetes, and more extensive atherosclerotic disease. The occurrence of a TVF or a non-TVF as the first event did not seem to influence subsequent outcomes. TRIAL REGISTRATION NUMBER: NCT04462315.

Relationship between stent length and very long-term target lesion failure following percutaneous coronary intervention for ST-elevation myocardial infarction in the drug-eluting stents era: insights from the EXAMINATION-EXTEND study.

BACKGROUND: Little data exist on the relationship between total stent length (TSL) and cardiovascular outcomes at very-long follow-up in patients with ST-elevation myocardial infarction (STEMI) in the 2nd generation drug-eluting stents (DES) era. AIM: To analyze the relationship between TSL and 10-year target-lesion failure (TLF) in STEMI patients treated with percutaneous coronary intervention enrolled in the EXAMINATION-EXTEND. METHODS: The EXAMINATION-EXTEND was an extended-follow-up study of the EXAMINATION trial, which randomized 1:1 STEMI patients to receive DES or bare metal stent (BMS). The primary endpoint was TLF, defined as a composite of target lesion revascularization (TLR), target vessel myocardial infarction (TVMI), or definite/probable stent thrombosis (ST). Relationship between stent length and TLF was evaluated in the whole study group in a multiple-adjusted Cox regression model with TSL as a quantitative variable. Subgroup analysis was also performed according to stent type, diameter, and overlap. RESULTS: A total of 1,489 patients with a median TSL of 23 mm (Q1-Q318-35 mm) were included. TSL was associated with TLF at 10 years (adjusted HR per 5 mm increase of 1.07; 95% CI, 1.01-1.14; P = .02). This effect was mainly driven by TLR and was consistent regardless of stent type, diameter, or overlap. There was no significant relationship between TSL and TV-MI or ST. CONCLUSIONS: In STEMI patients, there is a direct relationship between TSL implanted in the culprit vessel and the risk of TLF at 10 years, mainly driven by TLR. The use of DES did not modify this association.

Impact of Age at the Time of the First ST-Elevation Myocardial Infarction on 10-Year Outcomes (from the EXAMINATION-EXTEND Trial).

The aim of this substudy of the EXAMINATION-EXTEND was to analyze 10-year outcomes according to the patient's age at the time of the first ST-elevation myocardial infarction (STEMI). Of 1,498 patients with STEMI included in the EXAMINATION-EXTEND study, those with a previous history of coronary ischemic even or ischemic stroke were excluded from this analysis. The remaining 1,375 patients were divided into 4 age groups: <55, 55 to 65, 65 to 75, and >75 years. The primary end point was 10-year patient-oriented composite end point (POCE) of all-cause death, any MI, or any revascularization. At 10-year follow-up, patients aged <55 years (adjusted hazard ratio [HR] 0.24, 95% confidence interval [CI] 0.18 to 0.31, p = 0.001), 55 to 65 years (adjusted HR 0.26, 95% CI 0.20 to 0.34, p = 0.001), and 65 to 75 years (adjusted HR 0.38, 95% CI 0.30 to 0.50, p = 0.001) showed lower risk of POCE than those aged >75 years, led by a lower incidence of all-cause death (<55 : 6% vs 55 to 65: 11.9% vs 65 to 75: 25.7% vs >75 years: 61.6%, p = 0.001). Cardiac death was more prevalent in the older group (<55: 3.7% vs 55 to 65: 5.8% vs 65 to 75: 10.9% vs >75 years: 35.5%, p = 0.001). In the landmark analyses, between 5- and 10-year follow-up, young patients exhibited a higher incidence of any revascularization (<55: 7.4% vs 55 to 65: 4.9% vs 65 to 75: 1.8% vs >65 years: 1.6%, p = 0.001). In conclusion, in patients with a first STEMI, advanced age was associated with high rates of POCE at 10-year follow-up due to all-cause and cardiac death. Conversely, younger patients exhibited a high risk of revascularization at long-term follow-up.

Impact of Diabetes on 10-Year Outcomes Following ST-Segment-Elevation Myocardial Infarction: Insights From the EXAMINATION-EXTEND Trial.

Background Long-term outcomes of ST-segment-elevation myocardial infarction in patients with diabetes have been barely investigated. The objective of this analysis from the EXAMINATION-EXTEND (10-Years Follow-Up of the EXAMINATION trial) trial was to compare 10-year outcomes of patients with ST-segment-elevation myocardial infarction with and without diabetes. Methods and Results Of the study population, 258 patients had diabetes and 1240 did not. The primary end point was patient-oriented composite end point of all-cause death, any myocardial infarction, or any revascularization. Secondary end points were the individual components of the primary combined end point, cardiac death, target vessel myocardial infarction, target lesion revascularization, and stent thrombosis. All end points were adjusted for potential confounders. At 10 years, patients with diabetes showed a higher incidence of patient-oriented composite end point compared with those without (46.5% versus 33.0%; adjusted hazard ratio [HR], 1.31 [95% CI, 1.05-1.61]; P=0.016) mainly driven by a higher incidence of any revascularization (24.4% versus 16.6%; adjusted HR, 1.61 [95% CI, 1.19-2.17]; P=0.002). Specifically, patients with diabetes had a higher incidence of any revascularization during the first 5 years of follow-up (20.2% versus 12.8%; adjusted HR, 1.57 [95% CI, 1.13-2.19]; P=0.007) compared with those without diabetes. No statistically significant differences were found with respect to the other end points. Conclusions Patients with ST-segment-elevation myocardial infarction who had diabetes had worse clinical outcome at 10 years compared with those without diabetes, mainly driven by a higher incidence of any revascularizations in the first 5 years.

Sex Differences in 10-Year Outcomes Following STEMI: A Subanalysis From the EXAMINATION-EXTEND Trial.

BACKGROUND: Short-term outcomes following ST-segment elevation myocardial infarction (STEMI) in women are worse than in men, with a higher mortality rate. It is unknown whether sex plays a role in very long term outcomes. OBJECTIVES: The aim of this study was to assess whether very long term outcomes following STEMI treatment are influenced by sex. METHODS: EXAMINATION-EXTEND (10-Year Follow-Up of the EXAMINATION Trial) was an investigator-driven 10-year follow-up of the EXAMINATION (A Clinical Evaluation of Everolimus Eluting Coronary Stents in the Treatment of Patients With ST-Segment Elevation Myocardial Infarction) trial, which randomly 1:1 assigned 1,498 patients with STEMI to receive either everolimus-eluting stents or bare-metal stents. The present study was a subanalysis according to sex. The primary endpoint was the composite patient-oriented endpoint (all-cause death, any myocardial infarction, or any revascularization) at 10 years. Secondary endpoints were individual components of the primary endpoint. All endpoints were adjusted for age. RESULTS: Among 1,498 patients with STEMI, 254 (17%) were women. Overall, women were older, with more arterial hypertension and less smoking history than men. At 10 years, no difference was observed between women and men for the patient-oriented composite endpoint (40.6% vs 34.2%; adjusted HR: 1.14; 95% CI: 0.91-1.42; P = 0.259). There was a trend toward higher all-cause death in women vs men (27.6% vs 19.4%; adjusted HR: 1.30; 95% CI: 0.99-1.71; P = 0.063), with no difference in cardiac death or other endpoints. CONCLUSIONS: At very long term follow-up, there were no differences in the combined patient-oriented endpoint between women and men, with a trend toward higher all-cause death in women not driven by cardiac death. The present findings underline the need for focused personalized medicine in women after percutaneous revascularization aimed at both cardiovascular and sex-specific risk factor control and targeted treatment.

10-Year Follow-Up of Patients With Everolimus-Eluting Versus Bare-Metal Stents After ST-Segment Elevation Myocardial Infarction.

BACKGROUND: Outcomes data for a durable-polymer everolimus-eluting stent (EES) at extended long-term follow-up in patients with ST-segment elevation myocardial infarction (STEMI) are unknown. OBJECTIVES: The aim of this study was to assess the 10-year outcomes of patients enrolled in the EXAMINATION (A Clinical Evaluation of Everolimus Eluting Coronary Stents in the Treatment of Patients With ST-Segment Elevation Myocardial Infarction) trial. METHODS: The EXAMINATION-EXTEND (10-Years Follow-Up of the EXAMINATION Trial) study is an investigator-driven 10-year follow-up of the EXAMINATION trial, which randomly assigned 1,498 patients with STEMI in a 1:1 ratio to receive either EES (n = 751) or bare-metal stents (n = 747). The primary endpoint was a patient-oriented composite endpoint of all-cause death, any myocardial infarction, or any revascularization. Secondary endpoints included a device-oriented composite endpoint of cardiac death, target vessel myocardial infarction, or target lesion revascularization; the individual components of the combined endpoints; and stent thrombosis. RESULTS: Complete 10-year clinical follow-up was obtained in 94.5% of the EES group and 95.9% of the bare-metal stent group. Rates of the patient-oriented composite endpoint and device-oriented composite endpoint were significantly reduced in the EES group (32.4% vs. 38.0% [hazard ratio: 0.81; 95% confidence interval: 0.68 to 0.96; p = 0.013] and 13.6% vs. 18.4% [hazard ratio: 0.72; 95% confidence interval: 0.55 to 0.93; p = 0.012], respectively), driven mainly by target lesion revascularization (5.7% vs. 8.8%; p = 0.018). The rate of definite stent thrombosis was similar in both groups (2.2% vs. 2.5%; p = 0.590). No differences were found between the groups in terms of target lesion revascularization (1.4% vs. 1.3%; p = 0.963) and definite or probable stent thrombosis (0.6% vs. 0.4%; p = 0.703) between 5 and 10 years. CONCLUSIONS: At 10-year follow-up, EES demonstrated confirmed superiority in combined patient- and device-oriented composite endpoints compared with bare-metal stents in patients with STEMI requiring primary percutaneous coronary intervention. Between 5- and 10-year follow-up, a low incidence of adverse cardiovascular events related to device failure was found in both groups. (10-Years Follow-Up of the EXAMINATION Trial; NCT04462315).

Impacto en la mortalidad tras la implantación de una red de atención al infarto agudo de miocardio con elevación del segmento ST. Estudio IPHENAMIC / Impact on mortality after implementation of a network for ST-segment elevation myocardial infarction care. The IPHENAMIC study

INTRODUCCIÓN Y OBJETIVOS: Se sabe muy poco del impacto que las redes de atención del infarto agudo de miocardio con elevación del segmento ST (IAMCEST) tienen en la población. El objetivo de este estudio es averiguar si el PROGALIAM (Programa Gallego de Atención al Infarto Agudo de Miocardio) mejoró la supervivencia en la zona norte de Galicia. MÉTODOS: Se recogieron todos los eventos codificados como IAMCEST entre 2001 y 2013. Se identificó a 6.783 pacientes, divididos en 2 grupos: pre-PROGALIAM (2001-2005), 2.878 pacientes, y PROGALIAM (2006-2013), 3.905 pacientes. RESULTADOS: En la etapa pre-PROGALIAM, la mortalidad ajustada a 5 años fue superior tanto en la población total (HR=1,22; IC95%, 1,14-1,29; p < 0,001), como en cada una de las áreas (A Coruña, HR=1,12; IC95%, 1,02-1,23; p = 0,02; Lugo, HR=1,34; IC95%, 1,2-1,49; p <0,001, y Ferrol, HR=1,23; IC95%, 1,1-1,4; p = 0,001). Antes del PROGALIAM, la mortalidad a 5 años en las áreas de Lugo (HR=0,8; IC95%, 0,67-0,95; p = 0,02) y Ferrol (HR=0,75; IC95%, 0,64-0,88; p = 0,001) era superior que en A Coruña. Estas diferencias desaparecieron tras el desarrollo de la red (Lugo comparado con A Coruña, HR=0,88; IC95%, 0,72-1,06; p = 0,18; Ferrol comparado con A Coruña, HR=1,04; IC95%, 0,89-1,22; p = 0,58. CONCLUSIONES: El desarrollo del PROGALIAM en el área norte de Galicia disminuyó la mortalidad e incrementó la equidad de los pacientes con IAMCEST tanto en general como en cada una de las áreas donde se implantó

INTRODUCTION AND OBJECTIVES: Little is known about the impact of networks for ST-segment elevation myocardial infarction (STEMI) care on the population. The objective of this study was to determine whether the PROGALIAM (Programa Gallego de Atención al Infarto Agudo de Miocardio) improved survival in northern Galicia. METHODS: We collected all events coded as STEMI between 2001 and 2013. A total of 6783 patients were identified and divided into 2 groups: pre-PROGALIAM (2001-2005), with 2878 patients, and PROGALIAM (2006-2013), with 3905 patients. RESULTS: In the pre-PROGALIAM period, 5-year adjusted mortality was higher both in the total population (HR, 1.22, 95%CI, 1.14-1.29; P <.001) and in each area (A Coruña: HR, 1.12; 95%CI, 1.02-1.23; P=.02; Lugo: HR, 1.34; 95%CI, 1.2- 1.49; P <.001 and Ferrol: HR, 1.23; 95%CI, 1.1-1.4; P=.001). Before PROGALIAM, 5-year adjusted mortality was higher in the areas of Lugo (HR, 1.25; 95%CI, 1.05-1.49; P=.02) and Ferrol (HR, 1.32; 95%CI, 1.13-1.55; P=.001) than in A Coruña. These differences disappeared after the creation of the STEMI network (Lugo vs A Coruña: HR, 0.88; 95%CI, 0.72-1.06; P=.18, Ferrol vs A Coruña: HR, 1.04; 95%CI, 0.89-1.22; P=.58. CONCLUSIONS: For patients with STEMI, the creation of PROGALIAM in northern Galicia decreased mortality and increased equity in terms of survival both overall and in each of the areas where it was implemented
