Dilated cardiomyopathy (DCM) is distinguished by ventricular chamber expansion, systolic dysfunction, and normal left ventricular (LV) wall thickness, and is mainly caused due to genetic or environmental factors; however, its aetiology is undetermined in the majority of patients. The focus of this work is on pathogenesis, small animal models, as well as the herbal medicinal approach, and the most recent advances in imaging modalities for patients with dilated cardiomyopathy. Several small animal models have been proposed over the last few years to mimic various pathomechanisms that contribute to dilated cardiomyopathy. Surgical procedures, gene mutations, and drug therapies are all characteristic features of these models. The pros and cons, including heart failure stimulation of extensively established small animal models for dilated cardiomyopathy, are illustrated, as these models tend to procure key insights and contribute to the development of innovative treatment techniques for patients. Traditional medicinal plants used as treatment in these models are also discussed, along with contemporary developments in herbal therapies. In the last few decades, accurate diagnosis, proper recognition of the underlying disease, specific risk stratification, and forecasting of clinical outcome, have indeed improved the health of DCM patients. Cardiac magnetic resonance (CMR) is the bullion criterion for assessing ventricular volume and ejection fraction in a reliable and consistent direction. Other technologies, like strain analysis and 3D echocardiography, have enhanced this technique's predictive and therapeutic potential. Nuclear imaging potentially helps doctors pinpoint the causative factors of left ventricular dysfunction, as with cardiac sarcoidosis and amyloidosis.
扩张型心肌病(DCM)的特征为心室腔扩张、收缩功能障碍和正常左心室(LV)壁厚度,主要由遗传或环境因素引起;然而,大多数患者的病因尚未确定。本工作的重点是发病机制、小动物模型以及草药医学方法,以及用于扩张型心肌病患者的成像方式的最新进展。近年来提出了几种小动物模型,以模拟导致扩张型心肌病的各种病理机制。这些模型的特点是手术程序、基因突变和药物治疗。这些模型的优缺点都进行了说明,包括心力衰竭刺激广泛建立的扩张型心肌病小动物模型,因为这些模型往往可以提供关键的见解,并有助于为患者开发创新的治疗技术。还讨论了这些模型中用作治疗的传统药用植物以及草药疗法的现代发展。在过去几十年中,准确的诊断、对潜在疾病的正确认识、特定的风险分层和临床结果的预测,确实改善了 DCM 患者的健康状况。心脏磁共振(CMR)是评估心室容积和射血分数的可靠和一致方向的金标准。应变分析和 3D 超声心动图等其他技术增强了该技术的预测和治疗潜力。核成像可能有助于医生确定左心室功能障碍的原因,如心脏结节病和淀粉样变性。
