Background

Lichen planus (LP) carries the increased risk of cardiovascular events as it is a chronic inflammatory disease. This study aimed at determining the relationship between total atrial conduction time (TACT), P-wave dispersion, and the left atrium (LA) global strain in the patients with LP.

Methods

Forty people as a control group and 40 patients with LP were included in this study. Patient assessed global longitudinal LA strain by two-dimensional speckle-tracking strain echocardiography.

Results

The global peak systolic LA myocardium strain during the left ventricular systole (LAGLSRs) and the global peak negative LA myocardial strain rate during the early ventricular diastole (LAGLSRe) values were significantly lower in the patients with LP in proportion to the control group according to the strain measurements (1.7 ± 0.07 vs. 1.9 ± 0.1%, p = 0.001; 1.23 ± 0.04 vs. 1.2 ± 0.08 s−1, p = 0.001), respectively. TACT value was found to be significantly longer (102.6 ± 6.3 ms) in the patients with LP than the control group (96.3 ± 5.3 ms, p = 0.001), considering the terms of the artial conduction features.

Conclusion

This study demonstrated that the subclinical cardiac involvement in LP can determine the prolonged TACT and the impaired left atrial myocardial deformation values.

Background

In addition to proinflammatory properties, eosinophils can stimulate platelet activation and enhance prothrombotic pathways. In this study, we aimed to investigate the association between the eosinophil percentage (EOS%) and major adverse cardiac events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI).

Methods

This study enrolled a total of 1,909 patients who were diagnosed with STEMI. Ventricular arrhythmia, reinfarction, the need for cardiopulmonary resuscitation, target vessel revascularization, congestive heart failure, and cardiovascular mortality during index hospitalization were defined as MACE.

Results

Three hundred and eighty patients (19.7%) reached the combined endpoint with MACE. The rates of inhospital mortality and MACE were significantly higher in low EOS% group as compared to high EOS% group (4% vs. 1.1%, p < 0.01 and 32.8% vs. 11.3%, p < 0.01, respectively). On multivariate logistic regression analyses, EOS% (OR = 0.44, p < 0.01) was found to be one of the independent predictors of MACE. The EOS% lower than 0.60 on admission predicted inhospital MACE with a sensitivity of 68% and a specificity of 72% (AUC: 0.684, p < 0.01).

Conclusions

Low EOS% on admission may be associated with high inhospital MACE in STEMI patients. EOS% may be used as a novel biomarker for risk stratification of these patients.
