Spanish Registry of Acute Aortic Syndrome (RESA). Changes in therapeutic management and lower mortality in acute aortic syndrome.

INTRODUCTION AND OBJECTIVES: The Spanish Registry of Acute Aortic Syndrome (RESA) was launched in 2005 to identify the characteristics of acute aortic syndrome (AAS) in Spain. The aim of this study was to analyze the differences in management and mortality in the 3 RESA iterations. METHODS: We analyzed data from patients with AAS prospectively included by 24 to 30 tertiary centers during the 3 iterations of the registry: RESA I (2005-2006), RESA-II (2012-2013), and RESA III (2018-2019). RESULTS: AAS was diagnosed in 1902 patients (74% men; age, 60.7±12.5 years): 1329 (69.9%) type A and 573 (30.1%) type B. Comparison of the 3 periods revealed that the use of computed tomography increased as the first diagnostic technique (77.1%, 77.9%, and 84.2%, respectively; P=.001). In type A, surgical management increased (79.6%, 78.7%, and 84.5%; P=.045) and overall mortality decreased (41.2%, 34.5%, and 31.2%; P=.002), due to a reduction in surgical mortality (33.4%, 25.1%, and 23.9%; P=.003). In type B, endovascular treatment increased (22.8%, 32.8%, and 38.7%; P=.006), while medical and surgical treatment decreased. Overall type B mortality also decreased (21.6%, 16.1%, and 12.0%; P=.005) in line with a reduction in mortality with medical (16.8%, 13.8%, and 8.8%, P=.030) and endovascular (27.0%, 18.0%, and 9.2%; P=.009) treatments. CONCLUSIONS: The iterations of RESA show a decrease in mortality from type A AAS, coinciding with an increase in surgical treatment and a reduction in surgical mortality. In type B, the use of endovascular treatment was associated with improved survival, allowing better management in patients with complications.

Risk predictors in a Spanish cohort with cardiac laminopathies. The REDLAMINA registry.

INTRODUCTION AND OBJECTIVES: According to sudden cardiac death guidelines, an implantable cardioverter-defibrillator (ICD) should be considered in patients with LMNA-related dilated cardiomyopathy (DCM) and ≥ 2 risk factors: male sex, left ventricular ejection fraction (LVEF) <45%, nonsustained ventricular tachycardia (NSVT), and nonmissense genetic variants. In this study we aimed to describe the clinical characteristics of carriers of LMNA genetic variants among individuals from a Spanish cardiac-laminopathies cohort (REDLAMINA registry) and to assess previously reported risk criteria. METHODS: The relationship between risk factors and cardiovascular events was evaluated in a cohort of 140 carriers (age ≥ 16 years) of pathogenic LMNA variants (54 probands, 86 relatives). We considered: a) major arrhythmic events (MAE) if there was appropriate ICD discharge or sudden cardiac death; b) heart failure death if there was heart transplant or death due to heart failure. RESULTS: We identified 11 novel and 21 previously reported LMNA-related DCM variants. LVEF <45% (P=.001) and NSVT (P <.001) were related to MAE, but not sex or type of genetic variant. The only factor independently related to heart failure death was LVEF <45% (P <.001). CONCLUSIONS: In the REDLAMINA registry cohort, the only predictors independently associated with MAE were NSVT and LVEF <45%. Therefore, female carriers of missense variants with either NSVT or LVEF <45% should not be considered a low-risk group. It is important to individualize risk stratification in carriers of LMNA missense variants, because not all have the same prognosis.

Impact of Preoperative Pulmonary Hypertension on Survival in Patients Undergoing Elective Heart Transplant.

BACKGROUND: Pulmonary arterial hypertension (PAH) represents a marker of bad prognosis in left heart disease. Nonetheless, the effect on survival after heart transplant remains controversial. The objective was to study the impact of preoperative PAH on survival in patients undergoing elective heart transplant. METHODS: A retrospective study of 173 transplant recipients was conducted at a single hospital from January 2009 to December 2018. Congenital etiology and emergent heart transplant were exclusion criteria as well as those patients without enough data in the hemodynamic study. Two groups were considered: A (without PAH) and B (with HTP). PAH was classified as mild (mean pulmonary arterial pressure [mPAP] 25-34 mm Hg, pulmonary vascular resistance [PVR] 2.5-3.4 Wood units and/or transpulmonary gradient [TPG] 13-16 mm Hg), moderate (mPAP 35-44 mm Hg, PVR 3.5-4.9 Wood units and/or TPG 17-19 mm Hg), and severe (mPAP > 44 mm Hg, PVR > 4.9 Wood units and/or TPG > 19 mm Hg). RESULTS: A total of 102 patients were enrolled; 71.6% were male and average age was 52.3 (SD, 10.02) years. The main etiology was ischemic cardiomyopathy; 13.7% underwent previous heart operations. A total of 61 patients (59.8%) had PAH prior to heart transplant: 25 mild, 34 moderate, and 2 severe. Mean overall survival after transplant was 79.9 (SD, 5.68) months, without differences between the 2 groups (P = .82). One-month survival was 89% (the main cause of mortality was primary graft dysfunction), and 1-year survival was 78%. Four patients required mechanical circulatory support during early post-transplant period. CONCLUSIONS: Preoperative PAH does not have a significant impact on survival in elective heart transplant.

Prognosis of patients with syncope seen in the emergency room department: an evaluation of four different risk scores recommended by the European Society of Cardiology guidelines.

AIM: To apply, analyze, and evaluate the four syncope risk scores recommended by the 2009 European guidelines and the different parameters that they use to predict death, syncope recurrence, and hospital readmission in the population seen in the emergency room department (ERD) for syncope. METHODS AND RESULTS: A total of 323 patients aged older than 14 years [mean age 59 (32-75) years] and seen in ERD for syncope over a 2-month period were included in the study; 50.7% were women. Patients were evaluated using the four risk scores and were followed up for at least 2 years. In all, 275 patients (85.2%) were discharged directly from ERD after evaluation. During 28±5 months of follow-up, 8% died, 18.3% presented a further syncopal episode, and 18.6% were readmitted to hospital. Only two of the four risk scores were useful in risk discrimination, but no statistically significant differences were detected between predicted risk and observed risk. Multivariate analysis indicated relationships between age and death, a history of cardiovascular disease and syncope recurrence, and between presyncopal palpitations and hospital readmission. CONCLUSION: Although a large number of events occur after syncope, the risk scores recommended by guidelines overestimate risk, but there were no statistically significant differences between observed and predicted risk.
