Resequencing the whole MYH7 gene (including the intronic, promoter, and 3' UTR sequences) in hypertrophic cardiomyopathy.

MYH7 mutations are found in ~20% of hypertrophic cardiomyopathy (HCM) patients. Currently, mutational analysis is based on the sequencing of the coding exons and a few exon-flanking intronic nucleotides, resulting in omission of single-exon deletions and mutations in internal intronic, promoter, and 3' UTR regions. We amplified and sequenced large MYH7 fragments in 60 HCM patients without previously identified sarcomere mutations.

Transplantation for complex congenital heart disease in adults: a subanalysis of the Spanish Heart Transplant Registry.

Background: Congenital heart diseases (CHDs) have high infant mortality in their severe forms. When adulthood is reached, a heart transplant (HTx) may be required. Spanish adult population transplanted for CHD was analyzed and compared with the most frequent causes of HTx and between different subgroups of CHD.

Clinical recommendations for the use of everolimus in heart transplantation.

Proliferation signal inhibitors (PSIs), everolimus (EVL), and sirolimus are a group of immunosuppressor agents indicated for the prevention of acute rejection in adult heart transplant recipients. Proliferation signal inhibitors have a mechanism of action with both immunosuppressive and antiproliferative effects, representing an especially interesting treatment option for the prevention and management of some specific conditions in heart transplant population, such as graft vasculopathy or malignancies. Proliferation signal inhibitors have been observed to work synergistically with calcineurin inhibitors (CNIs).

Clinical utility of NT-proBNP levels in late heart transplantation patients.

Background: The present work was aimed to describe NT-proBNP levels in heart transplant patients after the first year postsurgery.

Methods: NT-proBNP concentration was measured in 1231 samples from 142 patients when a routine four-month follow-up was carried out, including other biochemical and clinical examinations. Endomyocardial biopsies were performed only upon clinical suspicion of acute rejection.

A randomized multicenter comparison of basiliximab and muromonab (OKT3) in heart transplantation: SIMCOR study.

Background: Antilymphocytic antibodies have been long used for the prevention of acute rejection early after heart transplantation (HTx), but their adverse effects have limited their widespread use. Our aim was to evaluate the safety, tolerability, and efficacy of the novel anti-CD25 antibody basiliximab (BAS) compared with muromonab (OKT3).

Patients And Methods: In this multicenter study, 99 patients were randomly assigned to receive either BAS or OKT3 in the early post-HTx period.

[Myocardial Infarction Registry in Asturias: the RIMAS project].

Background And Objective: Spanish hospital registers of myocardial infarction (MI) are not uniform. The RIMAS project is trying to know the real situation of myocardial infarction in Asturias and to observe possible differences among hospitals and with other registers.

Patients And Method: It was a cohorts study using a hospital registry of patients with MI.

Assay of cytomegalovirus susceptibility to ganciclovir in renal and heart transplant recipients.

Ganciclovir (GCV) prophylaxis or pre-emptive therapy significantly reduce the rate of cytomegalovirus (CMV) disease and viremia, but increase the potential for emergence of ganciclovir-resistant CMV strains. The inhibitor concentration at 50% (IC(50)) of GCV from 156 CMV isolates from 59 renal or heart transplant recipients was calculated by means of a rapid phenotypic susceptibility assay. Twenty-seven strains were from 14 patients undergoing GCV therapy.
