Interventions

• Daratumumab + Bortezomib + Dexamethasone + Dapagliflozin — DRUG
  The treatment medication for enrolled patients must comply with the treatment regimen of Daratumumab + Bortezomib + Dexamethasone: subcutaneous injection of 1800mg of Daratumumab, d1, 8,15,22 (28 day cycle); (After 2 cycles of improvement in cardiac indicators, it can be adjusted to intravenous injection of daratumumab); Bortezomib 1.3 mg/m2 d1, 8, 15, 22; D1, 8, 15, 22; Dexamethasone 20 mg d1, 2, 8, 9, 15, 16, 22, 23. When NTProBNP is greater than 5400ng/ml, bortezomib 1.0mg/m2; When NTProBNP is greater than 8500ng/ml, bortezomib is 0.7mg/m2. When NTProBNP is greater than 10000ng/ml, bortezomib is temporarily not allowed; NTProBNP greater than 4500ng/ml dexamethasone starts at 10 mg/dose. All patients were given Dapagliflozin 10mg/day at the beginning of treatment (creatinine clearance rate greater than 20ml/min).
