摘要
目的分析急性心肌梗死早期病人心肌耗氧量影响因素.方法对42例AMI病人于入院1～7 d进行动态监测,记录病人安静时、活动时的心率、血压及心率、血压变动较大时病人的状态,计算D-P(心率与收缩压二项乘积,用以表示心肌耗氧量).结果在排便、进食、探视及做治疗时病人D-P值增大.结论对急性心肌梗死早期病人加强健康教育及病情监测尤为重要,只有有效控制心肌耗氧量增加的因素,才能减轻心脏负荷,使病人早日康复.
Objective To analyze the effects factors on myocardial oxygen consumption （MVO2） for patients with acute myocardial infarction （AMI） in the early stage. Methods 42 patients with AMI during the 1-7 days of hospitalization were surveyed, the results of electro cardiogram, blood pressure, heart rate and the state of the patients with obvious variation of the blood pressure were measures while at rest and activity. Result of dounle-product （D—P） was calculated using the formula： D—P= SBP × HR. Results D—P were increased after defecating, eating, visiting, accepting treatment. Conclusion Heath education and close observation were especially important for the patients with AMI in the early stage, only the effective control of factors contributing to the increase of MVO2 could decrease cardiac load and promote the patient＇s early recovery.
