IAMCEST en mujeres. Recuperación de la expectativa de vida tras la intervención coronaria percutánea / STEMI in women. Life expectancy recovery after primary percutaneous coronary intervention

Introducción y objetivos: La mortalidad tras un infarto agudo de miocardio con elevación del segmento ST (IAMCEST) sigue siendo alta a pesar de los avances médicos. Las mujeres están poco representadas en los estudios, lo que limita el conocimiento sobre su tratamiento y su pronóstico. Se desconoce si las mujeres tratadas con intervención coronaria percutánea (ICP) primaria recuperan una esperanza de vida similar a una población de referencia. El objetivo del estudio es determinar si las mujeres sometidas a ICP primaria recuperan una supervivencia similar a la población general de iguales edad y región. Métodos: Se incluyeron todos los IAMCEST desde enero de 2014 a octubre de 2021. Se emparejó la muestra con una población de referencia de iguales edad y región, obtenida del Instituto Nacional de Estadística. Se determinaron las supervivencias observada y esperada y el exceso de mortalidad (EM) mediante el método Ederer II. Se repitió el análisis para mujeres de edad ≤ 65 y> 65 años. Resultados: Se reclutó a 2.194 personas; 528 casos eran mujeres (23,9%). Entre las mujeres que sobrevivieron los primeros 30 días, los EM del 1.er, el 5.o y el 7.o año fueron del 1,6% (IC95%, 0,3-4), el 4,7% (IC95%, 0,3-10,1) y el 7,21% (IC95%, 0,5-15,1) respectivamente. Conclusiones: Las mujeres con un IAMCEST tratadas con ICP primaria que sobreviven al evento agudo reducen significativamente su EM y presentan una esperanza de vida similar a la de la población de referencia de iguales edad y región.(AU)

Introduction and objectives: Despite medical advances, mortality after ST-elevation myocardial infarction (STEMI) remains high. Women are often underrepresented in trials and registries, limiting knowledge of their management and prognosis. It is unknown whether life expectancy in women of all ages treated with primary percutaneous coronary intervention (PPCI) is similar to that in a reference population free of the disease. The main objective of this study was to determine whether life expectancy in women undergoing PPCI and surviving the main event returns to a similar level to that in the general population of the same age and region. Methods: We included all patients diagnosed with STEMI from January 2014 to October 2021. We matched women to a reference population of the same age and region from the National Institute of Statistics to determine observed survival, expected survival, and excess mortality (EM) using the Ederer II method. We repeated the analysis in women aged ≤ 65 and> 65 years. Results: A total of 2194 patients were recruited, of whom 528 were women (23.9%). In women surviving the first 30 days, EM at 1, 5 and 7 years was 1.6% (95%CI, 0.3-4), 4.7% (95%CI, 0.3-10.1), and 7.2% (95%CI, 0.5-15.1), respectively. Conclusions: EM was reduced in women with STEMI who were treated with PPCI and who survived the main event. However, life expectancy remained lower than that in a reference population of the same age and region.(AU)

Permanent Pacemaker Reduction Using Cusp-Overlapping Projection in TAVR: A Propensity Score Analysis.

OBJECTIVES: The aim of this study was to determine if modifying the classical implantation technique for self-expanding (SE) transcatheter aortic valve replacement to a novel cusp-overlapping projection (COP) technique results in a higher implantation depth (ID) and subsequently reduces the rate of permanent pacemaker implantation (PPMI). BACKGROUND: The COP technique presents the potential benefit of an optimized ID to reduce the rate of PPMI. However, only a few studies have compared clinical outcomes with those achieved using the standard technique. This is the first study to systematically evaluate this approach for SE transcatheter heart valves (THVs) in different populations METHODS: Beginning in February 2015, 444 patients were consecutively included. Propensity score matching was used to control baseline characteristics because of the observational nature of the study. In total, 161 pairs of patients were analyzed. Three methods were used to measure ID (noncoronary cusp [NCC] to the THV, mean of the NCC and the left coronary cusp [LCC] to the THV, and the deepest edge from the LCC and the NCC to the THV). RESULTS: ID was significantly higher in COP cases when measuring from the NCC (4.2 mm vs 5.3 mm; P < 0.001) and the mean from the NCC and the LCC (5.3 mm vs 5.9 mm; P = 0.04), but not from the deepest edge. The PPMI rate was lower in the COP group: 19 (11.8%) vs 35 (21.7%) (P = 0.03; relative risk: 0.54; 95% CI: 0.32-0.91). CONCLUSIONS: The present study showed that the COP technique significantly reduces PPMI in SE THV implantation compared with the classical implantation technique, with similar rates of complications.

Cusp-overlapping TAVI technique with a self-expanding device optimizes implantation depth and reduces permanent pacemaker requirement.

INTRODUCTION AND OBJECTIVES: This study aimed to determine the safety and efficacy of modifying the classic implantation technique for aortic transcatheter heart valve (THV) implantation to a cusp-overlap-projection (COP) technique to achieve a higher implantation depth and to reduce the burden of new permanent pacemaker implantation (PPMI) at 30 days. Aortic self-expanding THV carries an elevated risk for PPMI. A higher implantation depth minimizes the damage in the conduction system and may reduce PPMI rates. METHODS: From March 2017, 226 patients were consecutively included: 113 patients were treated using the COP implantation technique compared with the previous 113 consecutive patients treated using the classic technique. In all patients, implantation depth was assessed by 3 methods (noncoronary cusp to the THV, mean of the noncoronary cusp and the left coronary cusp to the THV, and the deepest edge from the left coronary cusp and the noncoronary cusp to the THV). RESULTS: The COP group had a lower implantation depth than the group treated with the classic technique (4.8 mm± 2.2 vs 5.7 mm± 3.1; P=.011; 5.8 mm± 3.1 vs 6.5 mm± 2.4; P=.095; 7.1 mm± 2.8 vs 7.4 mm±3.2; P=.392). Forty patients (17.7%) required a new PPMI after the 30-day follow-up but this requirement was significantly lower in the COP group (12.4% vs 23%, P=.036). The COP implantation technique consistently protected against the main event (OR, 0.45; 95%CI, 0.21-0.97; P=.043), with similar procedural success rates and complications. CONCLUSIONS: The COP implantation technique is a simple modification of the implantation protocol and provides a higher implantation depth of self-expanding-THV with lower conduction disturbances and PPMI rates.

STEMI, primary percutaneous coronary intervention and recovering of life expectancy: insights from the SurviSTEMI study.

INTRODUCTION AND OBJECTIVES: In the last few decades, there has been a continuous process of improvement in medical treatment and secondary prevention measures after ST-segment elevation myocardial infarction (STEMI). Patients older than 65 years are at increased risk of death due to this event. Our aim was to determine whether patients aged less than 65 years and 65 years and older experiencing a STEMI can recover a life expectancy similar to that of the general population of the same age, sex, and geographical region. METHODS: We included all patients experiencing a STEMI at our institution during a 6-year period in an observational-study (SurviSTEMI: survival in STEMI). We calculated their observed survival, expected survival, and excess mortality. We repeated all analyses for survivors of the acute event stratifying by 65 years. RESULTS: For patients aged <65 years who survived the STEMI, observed survival at 3 and 5 years of follow-up was 97.68% (95%CI, 96.05%-98.64%) and 94.14% (95%CI, 90.89%-96.25%), respectively. Expected survival at 3 and 5 years was 98.12% and 96.61%. For patients ≥ 65 years who survived the STEMI, observed survival at 3 and 5 years was 85.52% (95%CI, 82.23%-88.24%) and 75.43% (95%CI, 70.26%-79.83%), respectively. Expected survival at 3 and 5 years was 86.48% and 76.56%, respectively. CONCLUSIONS: For survivors of the acute event, life expectancy is fairly similar to that of the general population of the same age, sex, and geographical region.
