Contemporaneous monitoring of disease progression, in addition to early diagnosis, is important for the treatment of patients with chronic conditions. Chronic disease-related factors are not easily tractable, and the existing data sets do not clearly reflect them, making diagnosis difficult. The primary issue is that databases maintained by health care, insurance, or governmental organizations typically do not contain clinical information and instead focus on patient appointments and demographic profiles. Due to the lack of thorough information on potential risk factors for a single patient, investigations on the nature of disease are imprecise. We suggest the use of a latent Markov model with variables in a latent process because it enables the panel analysis of many forms of data. The purpose of this study is to evaluate unobserved factors in ischemic heart disease (IHD) using longitudinal data from electronic health records. Based on the results we designate states as healthy, light, moderate, and severe to represent stages of disease progression. This study demonstrates that gender, patient age, and hospital visit frequency are all significant factors in the development of the disease. Females acquire IHD more rapidly than males, frequently developing from moderate and severe disease. In addition, it demonstrates that individuals under the age of 20 bypass the light state of IHD and proceed directly to the moderate state.

使用具有协变量的潜在马尔可夫估计缺血性心脏病的疾病进展

除了早期诊断外,同时监测疾病进展对于慢性病患者的治疗也很重要。慢性病相关因素不易处理,现有数据集不能清楚地反映它们,给诊断带来困难。主要问题是医疗保健、保险或政府组织维护的数据库通常不包含临床信息,而是侧重于患者预约和人口统计资料。由于缺乏关于单个患者潜在危险因素的全面信息,因此对疾病性质的调查不准确。我们建议在潜在过程中使用带有变量的潜在马尔可夫模型,因为它可以对多种形式的数据进行面板分析。本研究的目的是使用电子健康记录中的纵向数据评估缺血性心脏病 (IHD) 中未观察到的因素。根据结果​​,我们将状态指定为健康、轻度、中度和重度,以代表疾病进展的阶段。这项研究表明,性别、患者年龄和医院就诊频率都是疾病发展的重要因素。女性患 IHD 的速度比男性快,通常由中度和重度疾病发展而来。此外,它表明 20 岁以下的人可以绕过 IHD 的轻度状态并直接进入中度状态。和严重代表疾病进展的阶段。这项研究表明,性别、患者年龄和医院就诊频率都是疾病发展的重要因素。女性患 IHD 的速度比男性快,通常由中度和重度疾病发展而来。此外,它表明 20 岁以下的人可以绕过 IHD 的轻度状态并直接进入中度状态。和严重代表疾病进展的阶段。这项研究表明,性别、患者年龄和医院就诊频率都是疾病发展的重要因素。女性患 IHD 的速度比男性快,通常由中度和重度疾病发展而来。此外,它表明 20 岁以下的人可以绕过 IHD 的轻度状态并直接进入中度状态。
