Establishment of a Predictive Model for Poor Prognosis of Incomplete Revascularization in Patients with Coronary Heart Disease and Multivessel Disease.

Objective: To establish a predictive model for poor prognosis after incomplete revascularization (ICR) in patients with multivessel coronary artery disease (MVD).

Methods: Clinical data of 757 patients with MVD and ICR after percutaneous coronary intervention (PCI) in the Affiliated Hospital of Chengde Medical University from January 2020 to August 2021 were retrospectively collected. The least absolute shrinkage and selection operator regression method was used to screen variables, and multivariate logistic regression was used to establish a predictive model.

5-Benzoyl-13-bromo-4-hy-droxy[2.2]paracyclo-phane.

The title compound, C(23)H(19)BrO(2), was synthesized from 13-bromo-4-hy-droxy[2.2]paracyclo-phane and benzoyl chloride. The hy-droxy and carbonyl groups are involved in intra-molecular O-H⋯O hydrogen bonding.
