摘　　要：目的:探讨L型钙通道阻滞药对运动康复前后冠心病患者血钙(Ca)、血磷(P)、碱性磷酸酶(ALP)和骨密度(BMD)的影响,为临床冠心病患者的安全用药提供参考依据。方法:30例女性冠心病患者,根据是否服用L型钙通道阻滞药被分为服药组(13例)和未服药组(17例)。首先测定受试者的Ca、P、ALP和BMD,然后她们在跑台上进行递增负荷运动实验为制定运动处方提供依据。之后进行为期12周的运动康复训练,康复训练后再次测量上述各指标。结果:①两组运动康复后均呈血钙增加、血磷降低,与运动康复前相比有显著性差异(P<0.05),碱性磷酸酶未服药组运动康复后呈显著升高(P<0.05);②运动康复后未服药组的血钙比服药组显著增高(P<0.05);③两组运动康复后双股骨和L2—L4的BMD、Z值与运动康复前比较均有增加趋势,但未达到显著性水平(P>0.05);④运动康复前后两组间双股骨和L2—L4的BMD、Z值无显著性差异(P>0.05)。结论:①12周的运动康复可以使血钙升高,钙通道阻滞药对运动引起的升钙作用有拮抗作用;②服用20周的L型钙通道阻滞药对冠心病患者的骨密度未见明显影响。Objective:To examine the effect of L-type calcium channel blockers management on serum calcium(Ca),phosphorus(P),alkaline phosphatase(ALP) and bone mineral density(BMD),to provide an evidence based reference for safe medication management in coronary heart disease patients during rehabilitation.Method:Thirty female coronary heart disease patients were divided into blockade group(n=13,took L-type calcium channel blockers therapy) and non-blockade group(n=17,didn't take blockers).The patients' calcium(Ca),posphorus(P),alkaline phosphatase(ALP) and bone mineral density(BMD) were measured.After that,they performed a graded exercise test on a motorized treadmill to obtain useful information for establishing exercise prescription.Then,the patients undertook a 12-week exercise based rehabilitation programme and were retested all the above-mentioned indices as pretraining at the end of the programme.Result:① After the exercise rehabilitation,significant changes were observed,Ca increased and P decreased in both groups,and ALP increased in non-blockade group,compared with those pre training(P<0.05);②After exercise rehabilitation significant higher elevation Ca were observed in non-blockade group compared with the blockade group(P<0.05);③ There was an increasing tendency for BMD and Z value of dual femur and L2—L4 in both groups post exercise rehabilitation,but the differences did not reach statistical significant level compared with those pre-training(P>0.05);④ There was no significant difference between the two groups in terms of BMD and Z value of dual femur and L2—L4 both pre and post exercise training(P>0.05).Conclusion:①Serum calcium level of patients increased through 12-week exercise rehabilitation,and the calcium channel blocker had antagonizing effect on the rising of calcium induced by exercise;②The 20-week L-type calcium channel blockers management showed no side effect on BMD in patients with coronary heart disease.
