Meanwhile, improvement of right ventricular dysfunction was seen in 68.8% (11/16) patients with evaluable diastolic dysfunction grade, while normalization of BNP/NT‐pro‐BNP was seen in 52.2% (12/23) patients with elevated baseline BNP/NT‐pro‐BNP levels at MM remission. This evidence concerns the gene NPPB and Miyoshi myopathy.
