ABSTRACT

Objective:

To analyze the relationship between red cell distribution width (RDW) and disease severity in patients with non-ST-elevation myocardial infarction.

Methods:

Seventy patients with non-ST-elevation myocardial infarction who received treatment in Chaozhou People's Hospital from June 2019 to June 2020 were included in the observation group. An additional 70 patients with ST-elevation myocardial infarction who concurrently received treatment in the same hospital were included in the control group. All patients underwent electrocardiography and blood biochemical index examination. RDW was compared between the observation and control groups. The relationship between RDW and the severity of non-ST-elevation myocardial infarction was analyzed.

Results:

RDW in the observation group was significantly higher than that in the control group [(14.60 ± 1.00) % vs. (13.06 ± 1.70) %, t = 5.884, P = 0.012). The detection rate of coronary artery thrombosis in the observation group was significantly higher than that in the control group [70.00% (49/70) vs. 50.00% (35/70), χ2 = 7.563, P = 0.002]. In the observation group, the area under the receiver operating characteristic (ROC) curve plotted taking RDW as the variable was 0.649 (95% CI 0.546-0.753, P = 0.006). When the critical value of RDW was 14%, the sensitivity and specificity of RDW in the prediction of non-ST-elevation myocardial infarction were 73% and 59% respectively. RDW was positively correlated with cardiac troponin I level ( r = 0.19, P = 0.006).

Conclusion:

In patients with non-ST-elevation myocardial infarction, the increase in RDW is related to myocardial injury and the increase in cardiac troponin I level. RDW can be used as an effective index to predict the severity of non-ST-elevation myocardial infarction.
