临床心力衰竭判断中的问题与逻辑性

The Problem and Logicality of the Cinical Diagnosis in Heart Failure

临床依据患者外在表征推断心衰的特异性低，缘于传统诊疗难以实测心功能。仅指患者耐受体力活动差异的心功能Ⅰ级～Ⅳ级分级标准缺乏心脏实情的印证。用外在的，多歧义的，存在大量主观虚拟的推论诊治心衰，有悖医道的客观真实属性。对疑似心衰者，临床应优先用超声把握心脏形态与功能证据并判明病因，也是临床干预心衰的必要逻辑前提。

Clinically it had lower specification of diagnosed patients according to their exteriorsymptoms and signs in heart failure （HF）. Because of cardiac function traditionally was difficult to be measured by doctors well and truly. I to IV grade of cardiac function levels in which patients could endure max laboring loads had no veritable proofs. Getting used to exterior, multi--discriminated represents and containing much hypothetical or deductive reasoning subjectively for diagnosing and treating HF,that would not avoided to disoblige the medical true objectiveness. Using echocardiography, first of all, doctors ought to grasp the left ventricular structure and its function contained the doubted HF patients, and found the pathogenesis of HF. That was the logical premises of the essence for clinical intervene in HF.
