Abstract

Purpose of Review

The purpose of this systematic review was to analyze the current literature and identify all known preoperative risk factors associated with an increased incidence of cardiac allograft vasculopathy.

Recent Findings

A total of 7 independent preoperative risk factors for cardiac allograft vasculopathy were identified, namely T. gondii seropositivity (HR 4.39, 1.26–15.62, p < 0.02), elevated body mass index (HR 1.116, 1.015–1.23, p < 0.02), 2–1 haptoglobin phenotype (HR 2.73, 1.03–7.19, p < 0.01), elevated low-density lipoproteins (OR 2.14, 1.02–4.46, p < 0.04), single-nucleotide polymorphism -201 matching (HR 11.9, 4.3–32.9, p < 0.01), stroke cause of death (HR 1.47, 1.04–2.09, p < 0.03), and pre-transplant hemodynamic instability (HR 1.79, 1.15–2.77, p < 0.01).

Summary

Cardiac allograft vasculopathy is the leading cause of death in patients who survive more than a few years following transplantation and is likely the limiting factor in expanding the average life expectancy post-transplant. The development of therapeutics targeting the multifactorial etiology of this vasculopathy would undoubtedly provide hope for patients whose time is currently limited.

Available from: https://www.ncbi.nlm.nih.gov/books/NBK555999/ This article was very formative in this review, because it contains the most current, peer-reviewed epidemiological statistics on CAV. Largely, the importance of our review is derived from the vast mortality of CAV, which was quantified based on the contents of this article.

This article was very significant in this review because it outlined the increasing mortality of heart transplant recipients due to CAV as time PT increased. The foundation for the claims on the potential for CAV to be the limiting factor in extending the average life expectancy for heart transplant recipients is derived partially from this article.

This study significantly contributed to this review by performing multivariable analysis of sex differences in outcomes of heart transplant patients via a prospective cohort study of more than 49,000 patients. Their study found that male gender was a risk factor CAV, but when this finding was subjected to meta-analysis, it failed to meet significance in our study.
