Ability of Nonstrain Diastolic Parameters to Predict Doxorubicin-Induced Cardiomyopathy: A Systematic Review With Meta-Analysis.

Abstract

Doxorubicin is an important cause of chemotherapy-induced cardiomyopathy. Prior studies have found conflicting results of whether nonstrain diastolic parameters can predict doxorubicin-induced cardiotoxicity. We performed a systematic review of English written publications using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following inclusion criteria were applied: cancer subjects, echo-derived nonstrain diastolic profile, and patients compared before and after treatment to predict systolic dysfunction. The following exclusion criteria were applied: other cardiotoxic agents, non-echo studies, or used protective medications. Meta-analysis was performed using comprehensive meta-analysis software V3 to calculate cumulative means, SD, and odds ratios (ORs). Only 4 studies were designed to predict doxorubicin-induced cardiotoxicity. Of the 7 common parameters identified among studies, only 4 were significant: mitral E [OR: 3.4; 95% confidence interval (CI): 1.5-7.8; P = 0.003]; lateral E' (OR: 3.7; 95% CI: 1.5-9.4; P < 0.005); mitral E/A (OR: 4.3; 95% CI: 2.1-8.9; P < 0.0001); and lateral S' (OR: 2.7; 95% CI: 1.2-5.8; P = 0.01). We found that conventional nonstrain diastolic parameters predicted doxorubicin-induced systolic dysfunction. Whether nonstrain diastolic parameters can be used to supplement strain imaging for predicting doxorubicin-induced systolic function warrants further investigation in larger studies.
