脉压与冠心病患者左室肥厚的关系探讨

The relationship between pulse pressure and left ventricular hypertrophy in patients with coronary heart disease

目的探讨冠心病患者左室肥厚与脉压的关系。方法将本院收治的96例冠心病患者根据脉压大小分为3组:A组30例,脉压≤45 mmHg;B组35例,55 mmHg≥脉压>45 mmHg;C组31例,脉压>55 mmHg。采用彩色超声心脏诊断仪测定舒张期室间隔厚度(IVST)、左室后壁厚度(PWT)、左室舒张末期内径(LVDd)、左室射血分数(LVEF)及左心室质量指数(LVMI)。结果 C组患者LVEF明显低于A、B组;LVMII、VST明显高于A、B组。结论脉压增高使冠心病患者左室肥厚更加明显,且心功能下降明显。

Objective To investigate the relationship between pulse pressure and left ven- tricular hypertrophy in patients with coronary heart disease. Methods Ninety- six patients admit- ted to hospital with coronary heart disease were divided into three groups according to the size of pulse pressure： group A, 30 patients, pulse pressure ≤ 45 mmHg; group B, 35 patients, 55 mmHg ≥ pulse pressure〉 45 mmHg; group C, 31 patients, pulse pressure〉 55 mmHg. Interven- tricular septal thickness （IVST）, left ventricular posterior wall thickness （PWT）, left ventricular end - diastolic diameter （LVDd）, left ventricular ejection fraction （LVEF） and left ventricular mass index （LVMI） were measured with the help of color ultrasound diagnostic cardiac diastolic. Results LVEF of Group was significantly lower than that of group A and group B . LVMI and IVST were significantly higher. Conclusion Increased pulse pressure can make left ventricular hypertrophy more obvious and heart function in patients with coronary heart disease significantly worsened.
