尽管没有直接的比较？

Patiromer and SZC have been studied in heart failure and both agents have demonstrated the ability to maintain normokalemia for extended periods of time with improved side effect profiles than existing potassium binders such as sodium polystyrene sulfate, though no direct comparisons have occurred. SZC has also shown promise in the treatment of acute hyperkalemia with its quick onset of action.

patiromer和SZC已经在治疗心力衰竭方面进行了研究，这两种药物都证明了与现有的钾结合剂（如聚苯乙烯硫酸钠）相比，这两种药物能够在更长的时间内保持正常的血钾水平，并减少了副作用，尽管没有进行直接比较。SZC起效快，在治疗急性高血钾方面也显示出良好的前景。

尽管没有直接的比较，指与  现有的钾粘合剂（如聚苯乙烯硫酸钠）没有直接的比较过？谢谢
