Burden of Recurrent Hospitalizations Following an Admission for Acute Heart Failure: Preserved Versus Reduced Ejection Fraction.

Abstract Introduction and objectives Heart failure with preserved ejection fraction and reduced ejection fraction share a high mortality risk. However, differences in the rehospitalization burden over time between these 2 entities remains unclear. Methods We prospectively included 2013 consecutive patients discharged for acute heart failure. Of these, 1082 (53.7%) had heart failure with preserved ejection fraction and 931 (46.2%) had heart failure with reduced ejection fraction. Cox and negative binomial regression methods were used to evaluate the risks of death and repeat hospitalizations, respectively. Results At a median follow-up of 2.36 years (interquartile range: 0.96-4.65), 1018 pat…

Prediction of long-term major events soon after a first ST-segment elevation myocardial infarction by cardiovascular magnetic resonance.

Cardiovascular magnetic resonance (CMR) predicts combined clinical events in post-ST-segment elevation myocardial infarction (STEMI) patients. However, its contribution to predicting long-term major events (ME: cardiac death and non-fatal myocardial infarction [MI]) is unknown. We aimed to assess whether CMR predicts long-term MEs when performed soon after STEMI.We prospectively recruited 546 STEMI patients between 2004 and 2012. The Left ventricular (LV) ejection fraction (LVEF,%), infarct size (IS), edema, hemorrhage, microvascular obstruction, and myocardial salvage were quantified by CMR at pre-discharge. During a mean follow-up of 840 days, 57 ME events (10%; 23 cardiac deaths, 34 non-…

Growth differentiation factor 15 and geriatric conditions in acute coronary syndrome

Abstract Background Growth differentiation factor 15 (GDF-15) is a marker of cell senescence. Age is a well-known determinant of GDF-15 levels, yet no study has analyzed the relationship between geriatric conditions and GDF-15. We hypothesize that geriatric conditions reflecting biological age might be stronger determinants of GDF-15 than chronological age in elderly patients with acute coronary syndrome. Methods A total of 208 patients (mean age = 78.3 ± 7.0 years) were included. Prior to discharge, a thorough geriatric assessment was performed and GDF-15 measured. Predictors of GDF-15 (transformed by its natural logarithm) were determined with linear regression. Furthermore, Cox regressio…

Clinical Evaluation Versus Undetectable High-Sensitivity Troponin for Assessment of Patients With Acute Chest Pain.

Decision-making in acute chest pain remains challenging despite normal (below ninety-ninth percentile) high-sensitivity troponin (hs-cTn). Some studies suggest that undetectable hs-cTn, far below the ninety-ninth percentile, might rule out acute coronary syndrome. We investigated clinical data in comparison to undetectable hs-cTnT. The study comprised 682 patients (November 2010 to September 2011) presenting at the emergency department with chest pain and normal hs-cTnT (14 ng/l). The main end point was major adverse cardiac events (MACE: death, myocardial infarction, readmission for unstable angina, or revascularization) at a 4-year median follow-up; secondary end point was 30-day MACE.

Carga de hospitalizaciones recurrentes tras una hospitalización por insuficiencia cardiaca aguda: insuficiencia cardiaca con función sistólica conservada frente a reducida

Introduction and objectives: Heart failure with preserved ejection fraction and reduced ejection fraction share a high mortality risk. However, differences in the rehospitalization burden over time between these 2 entities remains unclear. Methods: We prospectively included 2013 consecutive patients discharged for acute heart failure. Of these, 1082 (53.7%) had heart failure with preserved ejection fraction and 931 (46.2%) had heart failure with reduced ejection fraction. Cox and negative binomial regression methods were used to evaluate the risks of death and repeat hospitalizations, respectively. Results: At a median follow-up of 2.36 years (interquartile range: 0.96-4.65), 1018 patients …

Stress cardiovascular magnetic resonance and mortality in a registry of 2496 elderly patients with chronic coronary syndrome. Prognosis and decision-making

Abstract Funding Acknowledgements Type of funding sources: None. Background. In recent guidelines, non-invasive imaging techniques play a pivotal role in the management of chronic coronary syndrome (CCS). The elderly represent a large percentage of our routine CCS population and risk stratification in this scenario is challenging. The potential of vasodilator stress cardiovascular magnetic resonance (CMR) for this purpose is unknown. Purpose. We explore the prognostic value and the usefulness for decision-making of the ischemic burden determined by vasodilator stress CMR imaging in a large cohort of elderly patients with known or suspected CCS. Methods. The study group was made up of 2496 p…

Pronóstico a largo plazo de pacientes con IAMSEST y coronarias sin lesiones obstructivas según los distintos subtipos angiográficos

Resumen Introduccion y objetivos Hay evidencia discordante sobre el pronostico del infarto sin lesiones coronarias obstructivas (MINOCA). Ademas, existen pocos datos del impacto de sus subtipos angiograficos. Los objetivos del estudio son evaluar el impacto pronostico del MINOCA y sus subtipos angiograficos en el seguimiento a largo plazo. Metodos Se incluyo a 591 pacientes consecutivos con IAMSEST a los que se realizo una coronariografia. Los pacientes con MINOCA se clasificaron segun la angiografia en: coronarias lisas, irregularidades leves (estenosis  Resultados En total, 121 pacientes (20,5%) no tenian lesiones obstructivas. El MINOCA se asocio con una menor ocurrencia de MACE (p = 0,0…
