【摘要】 目的 针对曲美他嗪急性心肌梗死患者经皮冠状动脉介入治疗(PCI)后心功能左心室重构影响以及可能的机制进行探索。方法 80例急性心肌梗死患者, 随机分成观察组和对照组, 每组40例。对照组按照常规方式治疗, 观察组在常规治疗的基础上使用曲美他嗪治疗。对两组患者治疗后心脏指数(CI)、左心室射血分数(LVEF)、每搏输出量(SV)、左心室收缩末期容积指数(LVESVI)、心输血量(CO)等指标进行比较。结果 治疗后, 观察组CI为(4.87±1.28)min/m2, LVEF为(0.60±0.04)%, SV为(72.54±3.41)ml, LVESVI为(43.87±2.58)ml/m2, CO为(5.68±1.47)L/min;对照组CI为(3.45±1.21)min/m2, LVEF为(0.84±0.02)%, SV为(62.54±3.41)ml, LVESVI为(48.24±1.87)ml/m2, CO为(4.35±1.22)L/min;观察组患者SV、CI、LVEF、LVESVI、CO指标与对照组比较差异具有统计学意义(P

Research of possible mechanism and influence by trimetazidine on cardiac function and left ventricular reconstruction in acute myocardial infarction after interventional treatment LIAO Ceng-zhen. Affiliated Hospital of Guilin Medical University, Guilin 541001, China

【Abstract】 Objective To investigate possible mechanism and influence by trimetazidine on cardiac function and left ventricular reconstruction in acute myocardial infarction after percutanecus coronary intervention (PCI). Methods A total of 80 patients with acute myocardial infarction were randomly divided into observation group and control group, with 40 cases in each group. The control group received conventional therapy, and the observation group received additional trimetazidine to conventional therapy. Comparison was made on cardiac index (CI), left ventricular ejection fraction (LVEF), stroke volume (SV), left ventricular end systolic volume index (LVESVI) and cardiac output (CO) after treatment between the two groups. Results After treatment, the observation group had CI as (4.87±1.28) min/m2, LVEF as (0.60±0.04) %, SV as (72.54±3.41) ml, LVESVI as (43.87±2.58) ml/m2, and CO as (5.68±1.47) L/min. The control group had CI as (3.45±1.21) min/m2, LVEF as (0.84±0.02) %, SV as (62.54±3.41) ml, LVESVI as (48.24±1.87) ml/m2, and CO as (4.35±1.22) L/min. The difference of SV, CI, LVEF, LVESVI and CO had statistical significance between the observation group and the control group (P

急性心肌梗死主要因心K局部血液供应中断而使得患者在段时间内出现心肌缺血的症状, 其病发较为迅速, 若治疗不及时将直接危及到患者生命。在医疗技术持续发展下, PCI已在很大程度上提升了临床对该类患者治疗效果, 实现了对死亡率的有效控制[1]。但是, 该治疗方式可能对患者造成再灌注损伤, 严重时更可能使心肌细胞出现坏死与凋亡。为确保该治疗方式的综合效率, 必须对介入治疗中药物类型进行合理选择[2-5]。本次本院就主要对曲美他嗪在介入治疗中实际效果进行探索。
