目的 探讨缺血性J波与冠状动脉狭窄程度以及冠状动脉斑块类型之间的关系.方法 将60例动态心电图发现缺血性J波的急性冠脉综合征患者和60例动态心电图没有发现缺血性J波的急性冠脉综合征患者行冠状动脉造影检查,依据冠状动脉狭窄处的积分来判断狭窄的程度.0～4分为Ⅰ度,5～8分为Ⅱ度,≥8分为Ⅲ度;依据Ambrose分法将斑块形态分为Ⅰ、Ⅱ、Ⅲ型.分析冠状动脉狭窄程度与冠状动脉斑块类型与缺血性J波的关系.结果 两组患者冠状动脉狭窄程度间差异无统计学意义(u=0.02,P=0.98);两组患者冠状动脉斑块类型的分布间差异有统计学意义(χ~2=16.09,P=0.0003);缺血性J波与冠状动脉狭窄程度无相关性(r=0.24,P＞0.05),缺血性J波与冠状动脉病变类型呈正相关性(r=0.34,P＜0.05).结论 冠状动脉Ⅱ型斑块以及冠状动脉中度狭窄的患者缺血性J波发生率高,可作为心肌缺血超急性期缺血改变的预测指标.
目的 探討缺血性J波與冠狀動脈狹窄程度以及冠狀動脈斑塊類型之間的關繫.方法 將60例動態心電圖髮現缺血性J波的急性冠脈綜閤徵患者和60例動態心電圖沒有髮現缺血性J波的急性冠脈綜閤徵患者行冠狀動脈造影檢查,依據冠狀動脈狹窄處的積分來判斷狹窄的程度.0～4分為Ⅰ度,5～8分為Ⅱ度,≥8分為Ⅲ度;依據Ambrose分法將斑塊形態分為Ⅰ、Ⅱ、Ⅲ型.分析冠狀動脈狹窄程度與冠狀動脈斑塊類型與缺血性J波的關繫.結果 兩組患者冠狀動脈狹窄程度間差異無統計學意義(u=0.02,P=0.98);兩組患者冠狀動脈斑塊類型的分佈間差異有統計學意義(χ~2=16.09,P=0.0003);缺血性J波與冠狀動脈狹窄程度無相關性(r=0.24,P＞0.05),缺血性J波與冠狀動脈病變類型呈正相關性(r=0.34,P＜0.05).結論 冠狀動脈Ⅱ型斑塊以及冠狀動脈中度狹窄的患者缺血性J波髮生率高,可作為心肌缺血超急性期缺血改變的預測指標.

Objective To investigate the relationship of ischemic J wave to coronary artery (CA) plaque types and coronary artery stenosis (CAS).Methods Coronary angiography was performed in 60 acute coronary syndrome patients with ECG ischemic J-wave and 60 without.The degrees of stenosis were judged according to the CAS scores,taking 0～4 as degree I,5～8 as degree Ⅱ,≥8 as degree Ⅲ,and plaque morphology divided into types Ⅰ,Ⅱ,Ⅲ based on Ambrose law,to analyze the relationship of ischemic J wave to CAS degrees and CA plaque types.Results There was not significant difference in CAS degree between 2 groups (u=0.0195,P=0.9845),but there was in distribution of CA plaque (χ~2=16.0890,P=0.0003).Ischemic J wave was not correlated with CAS degree (r=0.24,P＞0.05),but positively correlated with CA lesion type (r=0.34,P＜0.05).Conclusion Patients with type Ⅱ plaques or middle-degree CAS have a high incidence of ischemic J wave,which can be used as a predictor for ischemic changes of super-acute phase of myocardial ischemia.
