Heart failure , or the heart cannot pump out blood effectively to match the body s demands , will cause a substantial fall in quality of life with symptoms of breathlessness on mild exertion , swelling of the legs and body , and fatigue . patients may lose ability to perform daily tasks and to work 心脏衰竭患者因不能有效供血予身体所需，会出现气喘、身体或脚肿及疲倦的症状，他们的生活质素普遍很差，不少患者会丧失工作能力，更甚连日常生活亦需要别人帮忙。
While the current criteria for determining the suitability of crt are very restrictive and not sensitive , the division of cardiology has employed cutting edge technology in echocardiography to diagnose and predict which patient group ( s ) will have the best response to crt . usually symptoms such as shortness of breath and fatigue can be easily neglected by patients and hence diagnosis will be delayed until very late or the situation is very severe and dangerous that hospitalization is required 患上心脏衰竭的病人可能会忽略气喘、疲倦的症状，延误诊断。心脏科人员利用尖端的超声波仪器及标测科技推断那类患上心脏衰竭的病人对心脏同步起搏疗法有最好反应，有效地挑选合适采用这项疗法的病人，比以往筛选病人进行该疗法的方法更准确及有效率，为心脏衰竭的治疗跨进重大的一步。
Alternatively , they could generate healthy specialized cells from patients who had donated their genetic material , and transplant them into tissues - - without the risk of prompting immune rejection - - to treat failing hearts , neurological diseases such as parkinson ' s disease and amyotrophic lateral sclerosis , spinal cord injury and diabetes 上述二者中，他们可从被诊为患遗传疾病的病人中生成指定的健康细胞，并将其移植培养为组织不存在排斥免疫方面的风险可治疗心脏衰竭，神经疾病如帕金森症，肌萎缩性(脊髓)侧索硬化症，骨髓病症和糖尿病。
Recent studies have shown encouraging results for this therapy . the division of cardiology is now employing cutting edge technology in echocardiography for early and accurate diagnosis of heart failure and to predict which patient group ( s ) will have the best response to crt , which will be a major step forward in treatment for the disease 最近的研究显示，这项疗法效果很好；心脏科人员更利用尖端的超声波仪器及标测科技作诊断及推断那类患上心脏衰竭的病人对心脏同步起搏疗法有最好反应，为心脏衰竭的治疗跨进重大的一步。
