Changes of plasma B-type natriuretic peptide levels after high-pressure post-dilation following coronary stent deployment.

Objective: To evaluate the changes of plasma B-type natriuretic peptide(BNP) levels after high-pressure post-dilation following coronary stent deployment.

Methods: A total of 173 patients undergoing percutaneous coronary intervention for the left anterior descending artery were enrolled into the study. All patients were divided into two groups: the conventional group and the post-dilation group.

[Serum parathyroid hormone levels predict hospitalization in outpatients of heart failure: a preliminary study].

Objective: To evaluate the predicative value of serum parathyroid hormone (PTH) levels in outpatients of heart failure (HF) for hospitalization.

Methods: A total of 102 consecutive HF outpatients were enrolled. The receiver operating characteristic (ROC) curves demonstrated the optimal cut-off points of PTH levels for hospitalization due to HF.
