The receiver operator characteristics (ROC) curves were obtained to assess predictive values of copeptin level, BNP level, LVEF, and LA volume for all cases, cases with dilated and restrictive cardiomyopathies, and cases with hypertrophic and LV non-compaction cardiomyopathies, as illustrated in Figure 3. The gene discussed is NPPB; the disease is restrictive cardiomyopathy.
