Modified Wenshen Yixin Formula(温肾益心方加减)for Coronary Heart Disease Complicated with Hypothy-roidism of Spleen-kidney Yang Deficiency:A Prospective Real-world Study of 51 Cases
Objective To observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula(温肾益心方加减,MWYF)as an auxiliary treatment of coronary heart disease(CHD)complicated with hypo-thyroidism of spleen-kidney yang deficiency.Methods A total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group(67 cases)and experimental group(68 cases)according to the patients'wishes of herbal medicine administration.The control group was given conven-tional western medicine,while the treatment group was additionally given MWYF,1 dose per day;both groups were treated for 8 weeks.The traditional Chinese medicine(TCM)syndrome scores,angina scores,SF-36 scores,thyroid function indicators including thyroid stimulating hormone(TSH),thyroxine(T4)and triiodothyronine(T3),as well as serum cyclic adenosine monophosphate(cAMP),cyclic guanosine monophosphate(cGMP),monocyte chemoat-tractant ligand 2(CCL2),and tumor necrosis factor-related activator protein(CD40L)levels before and after treat-ment were compared between the two groups.The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups.The effectiveness regarding TCM syndrome and angina pectoris was evaluated,and the safety was assessed.Results Bias was adjusted by matching on propensity score,and 102 cases were finally included in the statistical analysis,with 51 cases in each group.The total effective rate regarding TCM syndrome[94.12％(48/51)versus 64.71％(33/51)],the total effective rate regarding angina pectoris[80.39％(41/51)versus 62.75％(32/51)],and the reduction and discontinuation rate of thyroid hormone preparation[39.21％(20/51)versus 5.88％(3/51)]were significantly higher in the experimental group than those in the control group(P＜0.05 or P＜0.01).After treatment,the total TCM syndrome score,individual scores of major symptoms,the major symptoms score,the secondary symptoms score,angina pectoris score,and TSH level were significantly reduced(P＜0.01),while all dimensions of SF-36 scores,T4,T3,and cAMP levels significantly increased in both groups(P＜0.05 or P＜0.01).The dosage of thyroid hormone preparations and the levels of cGMP,CCL2,and CD40L in the experimental group significantly decreased after treatment(P＜0.01).When com-pared between the two groups after treatment,the total TCM syndrome score,the major symptoms score,the scores of individual major symptom(chest tightness,chest pain,fear of cold,cold limbs,waist and kness soreness and weakness),the secondary symptoms score,angina pectoris score,TSH,cGMP,CCL2,and CD40L levels of the experimental group were significantly lower than those of the control group(P＜0.05 or P＜0.01),while all dimension scores of SF-36,T4,T3,and cAMP levels were significantly higher(P＜0.01).A total of three adverse events occurred during treatment,none of which were judged to be related to the interventions of this study.Conclusion MWYF can significantly ameliorate the TCM syndrome,angina pectoris,quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency,and can promote the reduction and disconti-nuation of thyroid hormone preparations.The mechanism may be related to the regulation of cAMP/cGMP balance,the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.
