目的探讨急性心肌梗死时脉压差水平对其预后的影响。方法急性心肌梗死患者98例,据脉压差水平分两组,正常组:脉压差为30~50 mm Hg,对照组:脉压差≥50 mm Hg,对比分析两组的梗死后心绞痛、心律失常、心衰与病死率相比差异均有统计学意义。结论脉压差增大者,发生急性心肌梗死预后的不良。
Objective To investigate the effect of pulse pressure on the prognosis of patients with acute myocardial infarction. Methods A total of 98 patients with acute myocardial infarction were divided into two groups according to the pulse pressure difference. In the normal group, the pulse pressure difference was 30-50 mm Hg. In the control group, the pulse pressure difference was 50 mm Hg. The angina pectoris, Arrhythmia, heart failure and mortality compared to differences were statistically significant. Conclusion Increased pulse pressure difference, the occurrence of acute myocardial infarction poor prognosis.
