Digoxin 的主要治療效果是改善心衰竭病人的心輸出量(cardiac output)。心輸出量提升後,腎臟灌流增加,腎小球過濾率(GFR)提升,進而使尿量增加,水腫改善。因此,對於心衰竭病人而言,尿量增加是毛地黃治療效果良好的重要臨床指標。其他選項如心率過慢、黃色光暈皆為中毒或過量徵兆,而該藥本身不直接影響血鉀數值。
Digoxin improves cardiac output, which enhances renal perfusion and glomerular filtration rate, leading to increased urine output and reduced edema. Therefore, increased urinary output is a key indicator of therapeutic efficacy in heart failure patients.
