To further evaluate the clinical impact of CHF, deferred patients with CHF on the actual intervention date (NT-proBNP level > 900 pg/ml in combination with clinical symptoms; n = 89) were compared to those who were CHF-free at this time point (NT-proBNP level ≤ 900 pg/ml/no symptoms; n = 89). Here, NPPB is linked to congestive heart failure.
