目的 观察超声心动图(UCG)+心肌损伤标志物水平检测在急性心肌梗死(AMI)患者诊断中的应用价值。方法 选取2020年6月—2021年9月我院收治的74例AMI患者为观察组,另选取同期65例疑似AMI患者为对照组,2组均进行UCG检测,并对比入院后0~2 h、2~12 h、12~24 h心肌损伤标志物[肌酸激酶同工酶(CK-MB)、氨基末端脑钠肽前体(NT-proBNP)、肌钙蛋白(cTnI)、心脏型脂肪酸结合蛋白(H-FABP)]水平,分析心肌损伤标志物与AMI病情程度的关联性及UCG+心肌损伤标志物水平检测对AMI诊断的应用价值。结果 UCG检查结果显示观察组阳性率86.79%高于对照组9.23%(P＜0.001);对照组入院后各时间段CK-MB、NT-proBNP、cTnI、H-FABP水平差异无统计学意义(P＞0.05)观察组入院后各时间段CK-MB、NT-proBNP、cTnI、H-FABP水平均高于对照组(P＜0.05);Spearman相关分析可知,血清CK-MB、NT-proBNP、cTnI、H-FABP水平与AMI患者病情程度呈正相关(r₁=0.648,r₂=0.692,r₃=0.704,r₄=0.683,P＜0.05);受试者工作特征曲线(ROC)曲线分析显示,UCG+血清CK-MB、NT-proBNP、cTnI、H-FABP联合检测对AMI患者的诊断敏感度(85.14%)、特异度(100.00%)较高(P＜0.05)。结论 UCG+心肌损伤标志物水平检测应用于AMI患者有利于提高诊断敏感度、特异度,诊断价值较高。

目的 探讨血浆脑利钠肽前体(proBNP)和心肌损伤标志物(CK-MB和cTnI)联合检测对老年脓毒症患者心肌损伤及预后评估的临床意义。方法 选择60例老年脓毒症患者按病情严重程度分为一般脓毒症组和严重脓毒症组,另选取同期在我院行健康体检的同龄人30例作为对照组。比较三组和不同预后患者血浆proBNP、cTNI、CK-MB水平及急性生理和慢性健康状态评分Ⅱ(APACHE Ⅱ) ,并对各指标进行相关性分析。结果 脓毒症患者血浆proBNP、cTnI水平高于对照组,且严重脓毒症组APACHEⅡ评分高于一般脓毒症组(均P＜0. 05);死亡组患者其血浆中的proBNP,cTNI和CK-MB水平及APACHE Ⅱ评分均高于存活组患者(均P＜0.05),差异有统计学意义;严重脓毒症组患者血浆proBNP 水平与cTnI及CK-MB水平呈正相关性(P＜0.05); 血浆proBNP水平、cTnI水平、CK-MB水平分别与APACHEⅡ评分呈正相关性(P＜0.05)。结论 血浆proBNP 及cTnⅠ水平可有效反映老年脓毒症患者心肌受损程度,早期血浆proBNP、cTnI、CK-MB水平联合检测对老年脓毒症患者预后判断可能有重要临床意义。

Objective To study the clinical significance of cardiac injury biomarkers(CK-MB and cTnI) and pro-brain natriuretic peptide(proBNP) joint detection for prognosis value in Elderly sepsis. Methods Sixty elderly patients with sepsis were selected. According to the severity of disease divided into general and severe sepsis group.Meanwhile, 30 healthy volunteers as a control group. Comparative study of plasma proBNP, cTnI, CK-MB levels and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) in three groups;and the correlation analysis of the indicators. Results Compared with control group, the plasma levels of proBNP and cTnI were significantly higher in patients with sepsis; And the APACHEⅡ score in the severe sepsis group was significantly higher than the general sepsis group (P<0. 05). The plasma proBNP, cTnI, CK-MB level and APACHE Ⅱ scores in death group were significantly higher than the survival group (P<0. 05). The proBNP plasma levels, cTnⅠ and CK-MB levels in severe sepsis patients were positively correlated (P<0. 05); They were positively correlated between ProBNP level, cTnⅠ level and the APACHEⅡ score(P<0. 05). Conclusions ProBNP plasma levels and cTnⅠ can effectively reflect the extent of the cardiac damage in elderly sepsis; Early plasma proBNP level, cTnI and CK-MB combined detection of elderly sepsis may have important clinical significance.
