Clinical, electrocardiographic and echocardiographic findings of 32 patients age 90 years or older were analyzed to assess the prevalence, characteristics and correlates of left ventricular (LV) hypertrophy. All patients (mean age 92 years, range 90 to 98; 21 women and 11 men) were referred to the echocardiography laboratory with a definite or suspected cardiovascular diagnosis. LV hypertrophy, echocardiographically diagnosed by high LV mass index, was present in 28 patients. The LV mass index ranged from 105 to 215 g/m2 in men and 140 to 262 g/m2 in women. Electrocardiographic evaluation showed LV hypertrophy in only 5 patients. Five patients had low voltage on the electrocardiogram. There was no correlation between the LV mass index and presence of electrocardiographic LV hypertrophy or presence of low voltage on the electrocardiogram. LV hypertrophy was concentric in 19 and eccentric in 9. There was no correlation between types of LV hypertrophy and underlying cardiovascular disease or presence of electrocardiographic LV hypertrophy. It is concluded that LV hypertrophy is frequently present and has a wide range and heterogeneous character in very elderly patients with cardiovascular disease. In the tenth decade of life, echocardiography is a sensitive method for detecting, characterizing and classifying LV hypertrophy, whereas electrocardiography lacks sensitivity in detecting it.
对32例90岁及以上患者的临床、心电图和超声心动图检查结果进行分析,以评估左心室肥厚的患病率、特征及相关因素。所有患者(平均年龄92岁,范围90至98岁;21名女性和11名男性)因明确或疑似心血管疾病被转诊至超声心动图实验室。通过高左心室质量指数超声心动图诊断为左心室肥厚的患者有28例。男性左心室质量指数范围为105至215g/m²,女性为140至262g/m²。心电图评估仅5例显示左心室肥厚。5例心电图表现为低电压。左心室质量指数与心电图左心室肥厚的存在或心电图低电压的存在之间无相关性。左心室肥厚呈向心性的有19例,离心性的有9例。左心室肥厚类型与潜在心血管疾病或心电图左心室肥厚的存在之间无相关性。结论是,在患有心血管疾病的高龄患者中,左心室肥厚很常见,且范围广泛、特征各异。在生命的第十个十年,超声心动图是检测、描述和分类左心室肥厚的敏感方法,而心电图在检测左心室肥厚方面缺乏敏感性。
