摘　　要：目的:观察老年高血压左室肥厚(LVH)与非左室肥厚(NLVH)患者在运动心肺试验中各检测指标的变化,探讨左室质量指数(LVMI)与各指标相关性。方法:纳入116例老年高血压患者,根据LVMI水平分为NLVH组(n=74)及LVH组(n=42),测量两组无氧阈(AT)时摄氧量(VO2)、代谢当量(MET)、氧脉搏(VO2/HR)、相对摄氧量(VO2/kg),以及最大运动量(max)时摄氧量(VO2)、代谢当量(MET)、氧脉搏(VO2/HR)、相对摄氧量(VO2/kg),比较两组各数值的差异性及与LVMI相关性。结果:LVH组达到AT值时VO2显著低于NLVH组(P<0.05);两组达到AT值时MET、VO2/HR及VO2/kg比较,差异均无统计学意义(P>0.05)。LVH组达到max值时VO2、MET显著低于NLVH组(P<0.05);两组达到max值时VO2/HR及VO2/kg比较,差异均无统计学意义(P>0.05)。Pearson相关分析显示,LVH组VO2AT、VO2max、METAT、METmax、VO2/kgAT、VO2/kgmax与LVMI均呈负相关(r=-0.312、-0.376、-0.390、-0.475、-0.370、-0.492,P<0.05)。结论:老年高血压合并LVH患者出现VO2AT、VO2max、METmax下降,表明运动耐量受损,摄氧能力下降。Objective:To observe the changes of the difference of the indexes of exercise cardiopulmonary test in elderly patients with hypertension complicated with left ventricular hypertrophy(LVH) and non-left ventricular hypertrophy(NLVH),and to investigate the correlation between left ventricular mass index(LVMI) and various indexes.Method:A total of 116 elderly patients with hypertension were divided into the NLVH group(n=74) and the LVH group(n=42) according to the level of LVMI.The oxygen uptake(VO 2 ),metabolic equivalent(MET),oxygen pulse(VO 2 /HR),relative oxygen uptake(VO2 /kg) at anaerobic threshold(AT) and the oxygen uptake(VO2 ),metabolic equivalent(MET),oxygen pulse(VO2 /HR),relative oxygen uptake(VO2 /kg) at maximal exercise(max) in both groups were measured.The differences between the two groups of indexes and the correlation with LVMI were compared.Result:The level of VO 2 at AT in the LHV group was significantly lower than that of the NLVH group(P<0.05).While the levels of MET,VO2 /HR and VO2 /kg at AT were compared between the two groups,and the differences were not statistically significant(P>0.05).The levels of VO2 and MET at max in the LVH group were significantly lower than those of the NLVH group(P<0.05).While the levels of VO 2 /HR and VO 2 /kg were compared between the two groups,and the differences were not statistically significant(P>0.05). Pearson correlation analysis showed that VO 2 AT,VO 2 max,MET AT,MET max,VO2 /kg AT,VO 2 /kg max in the LHV group were negatively correlated with LVMI(r=-0.312,-0.376,-0.390,-0.475,-0.370,-0.492,P<0.05).Conclusion:The levels of VO 2 AT,VO2 max and MET max were decreased in elderly patients with hypertension complicated with LVH,indicating impaired exercise tolerance and decreased oxygen uptake.
