We present the results of a population based survey (The Mexico City Diabetes Study) in which the prevalence of myocardial infarction (MI) was estimated in 2282 subjects using Minnesota coded electrocardiograms (ECG). Participating individuals were men (941) and non-pregnant women (1341) between 35-64 years of age, residing in a low income area of Mexico City. Electrocardiograms were classified in three categories: definitive MI (pathological Q and QS patterns, all 1.1 codes) and prominent Q and QS patterns accompanied by negative T waves (all 1.2 codes accompanied by code 5.1 or 5.2 with the exception of 1.2.6. and 1.2.8.). Possible MI included minor Q and QS patterns (all 1.3 codes and codes 1.2.6. and 1.2.8.) and unlikely MI included all other codes. Two tracings were uncodeable (final n = 2280), ten ECGs were classified as "definitive", 39 met criteria for "possible". Due to the small number, both categories, definitive and possible were combined. The overall prevalence of MI was higher in men (3.2%) than women (1.4%). In men ECG evidence of a MI was associated with older age, higher systolic blood pressure, higher 2-h post-glucose challenge and higher fasting and post-glucose challenge insulinemia. No corresponding associations were observed in women although the number of events in women was small. The prevalence of MI in Mexico City appears to be lower than that observed in some Mexican-American populations in the southern U.S. where prevalence for men was estimated around 4% and for women 2.5% for the same age group.(ABSTRACT TRUNCATED AT 250 WORDS)
我们展示了一项基于人群的调查（墨西哥城糖尿病研究）的结果，该研究使用明尼苏达编码心电图（ECG）对2282名受试者的心肌梗死（MI）患病率进行了估计。参与调查的个体为年龄在35至64岁之间、居住在墨西哥城低收入地区的男性（941名）和非孕女性（1341名）。心电图被分为三类：确诊心肌梗死（病理性Q波和QS波型，所有1.1编码）以及伴有负向T波的显著Q波和QS波型（所有1.2编码伴有5.1或5.2编码，但1.2.6和1.2.8除外）。可能的心肌梗死包括轻微Q波和QS波型（所有1.3编码以及1.2.6和1.2.8编码），不太可能的心肌梗死包括所有其他编码。两份心电图无法编码（最终n = 2280），十份心电图被分类为“确诊”，39份符合“可能”的标准。由于数量较少，确诊和可能这两类被合并。男性心肌梗死的总体患病率（3.2%）高于女性（1.4%）。在男性中，心肌梗死的心电图证据与年龄较大、收缩压较高、葡萄糖耐量试验后2小时血糖较高以及空腹和葡萄糖耐量试验后胰岛素血症较高有关。在女性中未观察到相应的关联，尽管女性中的事件数量较少。墨西哥城心肌梗死的患病率似乎低于美国南部一些墨西哥裔美国人人群中观察到的患病率，在相同年龄组中，该人群男性患病率估计约为4%，女性为2.5%。（摘要截断于250字）
