– 前降支中段99％狭窄，回旋支近段90％狭窄， 远段50％狭窄。
• Definition of Significant CAD
– 70% diameter stenosis of 1 major epicardial artery segment.
– 50 % diameter stenosis of left main. – Although lesions of less stenosis can cause angina, they have

心绞痛特点
• SAVES U：
– Sudden onset; – Anterior chest; – Vague sensation; – Exercise precipitated; – Short duration; – Unanimous attack.

Grading of Angina Pectoris by CCSC
病史特点
• 男性，59岁 • 反复胸痛4个月，加重1个月。 • 胸痛呈压榨性与劳力有关。 • 有高血压，吸烟史。 • 有心脑血管病阳性家族史。 • 查体：体胖，无明显其他阳性发现。 • ECG：V4－V6，I，aVL ST 0.5-1mm.

Noninvasive Testing: Ultrafast Computed Tomography
• Ultrafast (electron beam) computed tomography (EBCT) for the detection and quantification of coronary calcification:
• Class I: 日常体力活动不引起心绞痛.
• Class II: 日常体力活动轻度受限.
• Class III: 日常体力活动明显受限.
• Class IV: 任何体力活动都引起症状，可以有休 息时心绞痛。

UAP 的主要临床表现
• Rest angina: Occurring at rest, usu. >20min, occurring within a week of presentation.
• New onset angina: At least CCSC III severity, <2 months of initial presentation.
• Increasing angina: Distinctly more frequent, longer in duration, lower in Threshold. (ie. Increased by at least one CCSC class in 2 months, to at least CCSC III severity)
• Absolute contraindications:
– MI in 2 days; – Significant arrhythmias; – Severe AS; – Symptomatic HF; – Acute PE; – Acute myocarditis or pericarditis; – Acute aortic dissection.

Noninvasive Testing: ECG/Chest X-ray
• ECG:
– Normal in 50% stable angina. – Abnormal in 50% angina (normal rest ECG). – Equivocal: QIII, QS in V1, V2. – Pseudonormalization of ST depression or T

心绞痛的鉴别 (2)
• Chest Wall – Costochondritis – Fibrositis – Rib fracture – Sternoclavicular arthritis – Herpes zoster (before the rash)
• Psychiatric
– Anxiety disorders
– Sensitivity (detection of calcium): 85-100%. – Specificity: 41-76%. – Positive predictive value: 55-84%. – Negative predictive value: 84-100%.
