Anticoagulation and Antiplatelet Regimen in Cardiac Transplant. Clinical Characteristics, Outcomes, and Blood Product Transfusion.

BACKGROUND: We aimed to evaluate the characteristics, clinical outcomes, and blood product transfusion (BPT) rates of patients undergoing cardiac transplant (CT) while receiving uninterrupted anticoagulation and antiplatelet therapy. METHODS: A retrospective, single-center, and observational study of adult patients who underwent CT was performed. Patients were classified into four groups: (1) patients without anticoagulation or antiplatelet therapy (control), (2) patients on antiplatelet therapy (AP), (3) patients on vitamin K antagonists (AVKs), and (4) patients on dabigatran (dabigatran). The primary endpoints were reoperation due to bleeding and perioperative BPT rates (packed red blood cells (PRBC), fresh frozen plasma, platelets). Secondary outcomes assessed included morbidity and mortality-related events. RESULTS: Of the 55 patients included, 6 (11%) received no therapy (control), 8 (15%) received antiplatelet therapy, 15 (27%) were on AVKs, and 26 (47%) were on dabigatran. There were no significant differences in the need for reoperation or other secondary morbidity-associated events. During surgery patients on dabigatran showed lower transfusion rates of PRBC (control 100%, AP 100%, AVKs 73%, dabigatran 50%, p = 0.011) and platelets (control 100%, AP 100%, AVKs 100%, dabigatran 69%, p = 0.019). The total intraoperative number of BPT was also the lowest in the dabigatran group (control 5.5 units, AP 5 units, AVKs 6 units, dabigatran 3 units; p = 0.038); receiving significantly less PRBC (control 2.5 units, AP 3 units, AVKs 2 units, dabigatran 0.5 units; p = 0.011). A Poisson multivariate analysis showed that only treatment on dabigatran reduces PRBC requirements during surgery, with an expected reduction of 64.5% (95% CI: 32.4%-81.4%). CONCLUSIONS: In patients listed for CT requiring anticoagulation due to nonvalvular atrial fibrillation, the use of dabigatran and its reversal with idarucizumab significantly reduces intraoperative BPT demand.

Tratamiento de la insuficiencia cardiaca: la cuenta atrás empieza en el momento del diagnóstico / Heart failure treatment: the countdown begins at diagnosis

Sacubitrilo-valsartán tiene demostrada eficacia en disminuir las hospitalizaciones y las muertes por insuficiencia cardiaca en los ensayos clínicos, y los datos de práctica clínica real corroboran su efectividad y su seguridad. Asimismo su uso temprano durante la hospitalización, incluso en pacientes con insuficiencia cardiaca de inicio y/o sin tratamiento previo, también parece ser seguro y recomendable para simplificar el tratamiento del paciente y facilitar la transición de cuidados. También tiene un efecto favorable sobre el remodelado cardiaco, como demuestran los resultados del estudio PROVE-HF, que es mayor con un inicio temprano y a dosis más altas en estudios observacionales.

Clinical trials have found that sacubitril-valsartan is effective in reducing the risk of hospitalization and death from heart failure and real-life data have confirmed the drug combination's effectiveness and safety. Moreover, early use during hospitalization, in both patients with de novo heart failure and previously untreated patients, also appears to be safe and is recommended for simplifying patient management and easing transitional care. In addition, sacubitril-valsartan has a beneficial effect on cardiac remodeling, as demonstrated by the results of the PROVE-HF study, which is greater with an early onset and at higher doses in observational studies.
