1 Zhi-Cheng JING, M.D; FCCP. Professor of Cardiology Pulmonary Circulation Center Tongji University School of Medicine Shanghai, China Pulmonary Arterial Hypertension: New insights into 2010

2 Patho-Anatomy of AMI

3 In 1891, the German pathologist Romberg observed that the heart of an individual, suffering from a stricture of the pulmonary arteries due to severe sclerosis, was double the size of a man´s fist. He again named this disease sclerosis of the pulmonary arteries.

5 原发性肺高血压 – 发病率 : 1-2/ 百万人口 – 成人女男比 1.7:1 – 平均发病年龄 36±15 岁 –1 年、 3 年和 5 年的生存 率分别为 68%, 48% 和 34% D‘ Alonzo GE, et al. Ann Intern med.1991;115:343-349 Rich S, et al. Ann Intern med. 1987;107:216-23

6 Long-term response with CCBs in IPAH First study to demonstrate 95% 5-year survival in a very select group of patients with IPAH who exhibited an acute vasodilator response to CCBs Rich S,et al.N Engl J Med. 1992;327:76-81.

7 Survival in IPAH Long-term CCB responders Rich et al. N Engl J Med 1992

8 经左前臂静脉漂浮导管检查

9 急性肺血管扩张试验 Rubin LJ et al. Ann Intern Med 2005; 143: 282-292

10 急性肺血管扩张试验 - 阳性标准 阳性 肺动脉平均压 降至 40 mm Hg 以下 肺动脉平均压 下降幅度超过 10 mm Hg 心输出量 增加或不变 IPAH 患者阳 性率仅为 10% 左右 其他类型肺动 脉高压患者阳 性率更低

11 阳性患者 PAP 92/34/59 mm Hg PAP 36/11/20 mm Hg CO 3.5 3L/minCO 2.94 L/min

12 急性肺血管扩张试验 - 药物的选择 吸入装置和浓度检测 装置复杂 吸入给药 安全耐受性好 需要配合 滴定静脉泵入 不良反应多 静脉泵入 国内未上市 NO 依前 列醇 腺苷 伊洛前列 环素 指南公认

36 Right heart remodeling and ischemia Right coronary artery flow will be decreased or stopped during the systol- period PA-RV-LV interaction NF. Voelkel, et al. Circulation, 2006; 114: 1883. HC. Champion, et al. Circulation, 2009; 120:992.

37 PAH is all about the RV Time PAP PVR CO Pre-symptomatic/ Compensated Symptomatic/ Decompensating Symptom Threshold RV Failure Declining/ Decompensated

38 Future: what we should do? To set up the truly therapy goal : pulmonary artery remodeling—occlusion---hemodynamic worse—heart remodeling—heart failure ( not only right heart failure, the wholely cardivascular system collapse ) To reverse the right heart pathological remodeling : stronger combination therapy to 1 ) control the pulmonary arerial spasm and contraction ; 2 ) stop and reverse the pulmonary vascular remodeling; 3 ) resolve the ischemia of myocardium To investigate who is the murderer to initiate the pulmonary arterial disease : not BMPRII mutation, maybe Virus infection on the pulmonary vascular bed?
