  心臟衰竭一直是心臟病變中,最大的挑戰。近幾年來,心臟衰竭的治療亦有一些突破,在基礎研究方面,如CUPID (Efficancy and safety study of genetically targeted enzyme replacement therapy for advanced heart failure) trial 的gene therapy,如STAR (Acute and long-term effect of intracoronary stem cell transplantation in chronic heart failure) heart study 的stem cell therapy….等人體試驗陸續有結果。在非藥物治療方面,心臟復健已漸漸成為顯學,JACC及JAMA分別於2009年發表老年冠狀動脈病患及HF-ACTION trial之心臟復健之臨床效果。Archives of Internal Medicine亦發表Tai Chi may benefit patients with heart failure等新論述。

  在藥物治療方面,a cardiac myosin activator “omecamtiv mecarbil 兩個clinical trial在Lancet發表。ASCEND-HF (Acute Study of Clinical Effectiveness of Nosiritide in Decompensated Heart Failure trial)發現Nesiritide對ADHF並沒有效果(NEJM 2011), JACC則發表了Supplementation with Omega-3 polyunsaturated fatty acids improved LV function in patients with mild to moderate chronic heart failure due to dilated cardiomyopathy。EPHESUS (Eplerenone Post-acute myocardial infarction Heart failure Efficacy and SUrvival Study)顯示post-MI 7天內eplerenone開始治療比7天後才開始治療有明顯效果,而EMPHASIS-HF (Eplerenone in Mild Patients Hospitalilzation And SurvIval Study in Heart Failure)由於臨床eplerenone有明顯之成效而提早結束研究之進行。

  在Device therapy方面,CRT-D (Cardiac Resynchronization Therapy with Defibrillator)對輕度心臟衰竭有其效果(Am J Cardiol 2011),在Annual of Internal Medicine亦有發表CRT improves outcomes in less symptomatic heart failure,RAFT(Resynchonization – defibillation for Ambulatory heart Failure Trial)亦繼MADIT-CRT (NYHA class I, II, 2009)之後顯示對NYHA class II or III LV systolic dysfunction,wide QRS complex之病患使用CRT-D治療較優於單獨使用ICD治療。在外科治療方面,CABG,mitral valve repair,LV reconstruction到heart transplantation在適合的indication之下,都是改善heart failure之外科治療選項之一。機械性循環輔助器,如心室輔助器等亦有不同機轉的新機型陸續發展,對末期心臟衰竭過渡期之穩定有正面之成效。本次專題討論,五個主題由國內該領域專家來演講,相信是精采可期。
