[Abstract] Objective To analyze the value of clinical diagnosis and ultrasonic diagnosis in coronary heart disease （CHD） with papillary muscle dysfunction （PMD）.Methods A total of 89 CHD-PMD patients diagnosed and treated from November 2018 to November 2020 were selected.Clinical diagnosis and ultrasonic diagnosis were carried out，and the diagnostic value of the two methods was compared. Results The rate of intermittent dyspnea at night was 78.65% by ultrasonic and 70.79% by clinical diagnosis.The rate of shortness of breath and palpitation was 77.53% by ultrasonic diagnosis and 71.91% by clinical diagnosis.The probability of lung rales was 74.16% by ultrasonic diagnosis and 67.42% by clinical diagnosis.The probability of left enlargement of cardiac boundary was 80.90% by ultrasonic diagnosis and 71.91% by clinical diagnosis，with no significant differences （P>0.05）. The positive rate of ultrasonic diagnosis was 86.52%，and that of clinical diagnosis was 71.91%.According to the pathological diagnosis certificate，the sensitivity of ultrasonic diagnosis was 97.33%，and that of clinical diagnosis was 74.24%.The specificity of ultrasonic diagnosis was 71.43%，and that of clinical diagnosis was 34.78%. The accuracy of ultrasonic diagnosis was 93.26%，and that of clinical diagnosis was 64.04%，with statistically significant differences （P<0.05）.The duration from onset to diagnosis was （1.29±0.84） months by ultrasonic diagnosis and （5.88±0.92） months by clinical diagnosis，with statistically significant difference （P<0.05）. Conclusion The accuracy of ultrasound in the diagnosis of CHD-PMD is significantly better than that of clinical diagnosis.These two methods show the similar diagnostic effect on clinical manifestations.Ultrasound examination can be carried out on the basis of clinical diagnosis to enhance the diagnostic effect.

乳頭肌功能失調(diào)（Papillary muscle dysfunction，PMD）是冠心病（Coronary heart disease，CHD）患者的主要并發(fā)癥，指房室瓣相連的乳頭肌出現(xiàn)壞死和缺血改變，進(jìn)而導(dǎo)致乳頭肌收縮障礙，這會(huì)造成房室瓣無(wú)法完全關(guān)閉，加重冠脈缺血情況。PMD會(huì)降低心臟功能，增加其他并發(fā)癥的發(fā)病風(fēng)險(xiǎn)，而且會(huì)影響CHD的治療預(yù)后[1-2]。臨床要求盡早診斷CHD-PMD，評(píng)估患者的病情程度，予以及時(shí)干預(yù)，進(jìn)而阻斷CHD疾病進(jìn)展。其常用的診斷方法為臨床診斷，可通過(guò)癥狀與體征診斷鑒別患者的病情嚴(yán)重程度，提高疾病陽(yáng)性檢出率。但是臨床診斷具有局限性，其缺乏影像學(xué)技術(shù)支持。為此，多加用超聲診斷，以增強(qiáng)診斷準(zhǔn)確率。本研究選取2018年11月至2020年11月間入院診斷的CHD-PMD患者89例，用于分析超聲診斷與臨床診斷的價(jià)值，現(xiàn)報(bào)道如下。
