目的：研究老年心脏肿瘤的病理形态及其临床意义。方法：对３２例老年心脏肿瘤（２９例心粘液瘤）进行临床分析和光镜、电镜观察。结果：心脏粘液瘤是老年人最主要的原发心脏肿瘤（占９０％以上），多见于女性（８７．５％）的左心房（８６．６％）；老年心脏肿瘤常伴随高血压和冠心病；超声心动图有诊断价值；栓塞是老年心脏粘液瘤的主要伴发症和死因，与其松脆的海棉状组织结构有关。结论：老年心脏肿瘤的临床病理特性与其自身生理状态密切相关 Objective: To study the pathological morphology and clinical significance of elderly cardiac tumors. Methods: Clinical analysis, light and electron microscopy were performed on 32 elderly cardiac tumors (29 cases of cardiac myxoma). RESULTS: Cardiac myxoma was the most prevalent primary cardiac tumor in the elderly (more than 90%), and was more common in the female (87.5%) left atrium (86.6%); elderly heart tumors were often accompanied by hypertension and coronary artery disease. Heart disease; Echocardiography has diagnostic value; Embolism is the main concomitant disease and cause of death in elderly cardiac myxoma, and is related to its crispy sponge-like tissue structure. Conclusion: The clinicopathological characteristics of elderly cardiac tumors are closely related to their physiological status
