Risk stratification model for in-hospital death in patients undergoing percutaneous coronary intervention: a nationwide retrospective cohort study in Japan.

ABSTRACT:

Objectives

To provide an accurate adjustment for mortality in a benchmark, developing a risk prediction model from its own dataset is mandatory. We aimed to develop and validate a risk model predicting in-hospital mortality in a broad spectrum of Japanese patients after percutaneous coronary intervention (PCI).

Design

A retrospective cohort study was conducted.

Setting

The Japanese-PCI (J-PCI) registry includes a nationally representative retrospective sample of patients who underwent PCI and covers approximately 88% of all PCIs in Japan.

Participants

Overall, 669 181 patients who underwent PCI between January 2014 and December 2016 in 1018 institutes.

Main outcome measures

In-hospital death.

Results

The study population (n=669 181; mean (SD) age,
