Heart failure is a common disease characterised by poor prognosis and frequent hospitalisations, constituting a major economic burden to society. Mortality and morbidity can be reduced by optimal treatment, requiring objective evaluation of cardiac function and anatomy. The development of symptomatic HF can be prevented by initiating adequate treatment in early stages when LVD is still asymptomatic. Asymptomatic patients can be identified only by screening for LVD among patients at risk of developing HF, such as those with IHD, HT, and diabetes. However, there is a severe lack of resources to assess cardiac function and anatomy in all patients at risk. Consequently, many patients with latent HF will remain undetected, and in patients with symptomatic HF treatment will not be optimal. Simplified echocardiography, a 5-minute echocardiogram based on visual estimation of cardiac function and anatomy, is an inexpensive and accurate method for diagnosis and screening for latent and symptomatic HF. The long axis shortening of the LV is related to LV function and can be measured by AVPD. Determination of left AVPD is a reliable, reproducible, readily mastered, quickly performed and, therefore, inexpensive method that can be used in almost all patients for evaluation of LV function, as well as for prognostication in HF. Left AVPD reflects both systolic and diastolic LV function. Simplified echocardiography is useful for screening of asymptomatic patients at risk of developing HF, and for routine diagnostic purposes in patients with symptoms suggestive of HF. In patients with LVSD, simplified echocardiography may be combined with a determination of left AVPD for prognostication and for optimal detection of changes in LV function over time.
心力衰竭是一种常见疾病,其特点是预后不良且频繁住院,给社会带来重大经济负担。通过优化治疗可降低死亡率和发病率,这需要对心脏功能和解剖结构进行客观评估。在左心室功能障碍(LVD)仍无症状的早期阶段开始充分治疗,可预防有症状心力衰竭的发生。只有通过在有发生心力衰竭风险的患者(如患有缺血性心脏病、高血压和糖尿病的患者)中筛查LVD,才能识别无症状患者。然而,评估所有有风险患者的心脏功能和解剖结构的资源严重短缺。因此,许多潜在心力衰竭患者将仍未被发现,并且有症状心力衰竭患者的治疗也不会达到最佳效果。简化超声心动图是一种基于对心脏功能和解剖结构的视觉估计的5分钟超声心动图检查,是诊断和筛查潜在及有症状心力衰竭的一种廉价且准确的方法。左心室的长轴缩短与左心室功能相关,可通过主动脉瓣平面内径(AVPD)测量。测定左AVPD是一种可靠、可重复、易于掌握、操作迅速且因此廉价的方法,可用于几乎所有患者评估左心室功能以及心力衰竭的预后。左AVPD反映左心室的收缩和舒张功能。简化超声心动图有助于筛查有发生心力衰竭风险的无症状患者,并用于有心力衰竭症状患者的常规诊断。对于左心室收缩功能障碍(LVSD)患者,简化超声心动图可与测定左AVPD相结合,用于预后评估以及随时间最佳检测左心室功能的变化。
