摘要
目的探讨心型脂肪酸结合蛋白(H-FABP)与急性期慢性阻塞性肺疾病(COPD)患者心肌损伤的相关性,评价其筛查COPD患者早期心肌损伤的临床价值。方法收集2014年2~6月确诊的急性期COPD住院患者38例为疾病研究组,急性期支气管炎患者20例为疾病对照组,健康体检者20例为健康对照组。检测所有入选者血清H-FABP,并同步测定住院患者血清TNI、CK-MB、CK、BNP水平,比较同时期的心电图、超声心动图、肺功能及血气分析结果,与H-FABP进行关联性分析。结果在38例COPD急性期患者中,有31例(81.6%)H-FABP阳性,7例(18.4%)H-FABP阴性,而健康及疾病对照组经检测均为阴性。AECOPD患者H-FABP阳性组与其阴性组比较:心电图异常率85.7%vs.33.3%;超声心动图提示右心肥大的概率66.7%vs.0%,差异均有统计学意义(P〈0.05)。肺功能检查显示:急性加重期(AECOPD)患者H-FABP阳性组FEV1/FVC、FEV1%预计值均要显著低于阴性组(t=-3.42,P〈0.05;t=-2.90,P〈0.05)。对AECOPD患者进行病情分级,结果显示Ⅲ、Ⅳ级患者H-FABP阳性率(100%)明显高于Ⅰ、Ⅱ级组(40%),P=0.01,差异有统计学意义。与传统的心肌标记物相比,TNI、CK-MB、CK对急性期COPD患者心肌损伤的诊断阳性率极低(〈5%)甚至为零,然而H-FABP阳性组相比阴性组,BNP水平(275.7±283.6)pg/ml vs.(35.1±28.8)pg/ml;TNI基线水平(0.015±0.024)ng/ml vs.(0.001±0.000)ng/ml,P〈0.05,差异有统计学意义。结论 H-FABP在评价急性期COPD心肌早期损伤中具有潜在的价值,其早期筛查方面要优于传统心肌指标如TNI、CK-MB、CK,可以作为COPD患者早期筛查心肌损伤、评估病情严重程度的灵敏指标。
Objective To explore the correlation between heart-type fatty acid-binding protein (H-FABP) and myocardial injury in patients with acute COPD (AECOPD), and to evaluate its clinical value in COPD patients with myocardial injury. Methods Thirty-eight patients with continued acute exacerbations of COPD as disease group, 20 patients with acute bronchitis as-disease control group, 20 cases of healthy subjects were collected from February to June of 2014. The levels of serum H-FABP, TNI, CK-MB, CK, BNP in AECOPD patients and control subjects were detected. The correlation was performed between the results such as the same period electrocardiogram, echocardiography, pulmonary function, blood gas analysis and H-FABP. Results Thirty-one cases(81.6%) were H-FABP positive and 7 cases(18.4%) were H-FABP negative in 38 patients with AECOPD. All subjects both in health and disease control groups were I-I-FABP negative. Compared with H-FABP positive group and its negative group in AECOPD patients, we found the results as follows: ECG abnormal rate 85.7% vs. 33.3%; the abnormality of fight ventricular hypertrophy prompted on eehocardiography 66.7% vs. 0%. Above all P〈0.05, the difference between them was significant statistically. The pulmonary function tests showed H-FABP positive group FEV1/FVC and FEVI% values were significantly lower than the negative group (t=3.42, P〈0.05, t=-2.90, P〈0.05). According to the disease classification for AECOPD patients, the results showed thatⅢ, IV grade H-FABP positive rate (100%) was significantly higher than I, Ⅱgrade group (40%), the difference was statistically significant (P=0.01). Compared to the traditional indicators of myocardial injury, TNI, CK-MB, CK-positive rate was very low (〈5%) or even zero for diagnosing myocardial injury in CODP patients. However, compared with H-FABP positive group and negative group, the level of BNP (275.7±283.6)pg/ml vs. (35.1±28.8)pg/ml; the baseline level of TNI (0.015±0.024)ng/ml vs. (0.001±0.000)ng/ml were all statistically significant (P〈0.05). Conclusion H-FABP has a potential value in the evaluation of early myocardial injury in AECOPD patients and it is superior to the traditional indicators such as TNI, CK-MB, CK. H-FABP can use an effective indicator to screen early myocardial damage and to assess the severity of disease in AECOPD patients.
