AIM: The aim of the study was to determine the predictive possibility of the GDF-15 marker in the stratification of the ACS complications risk within 5 years after the event.
MATERIALS AND METHODS: 70 patients with ACS were involved. The mean age was (61.8 +/- 1.3) years, the following diagnosis was established in the patients: 76 patients had acute myocardial infarction with Q (AMI with Q), 28 - acute myocardial infarction without Q (AMI without Q) and 36 patients were diagnosed unstable angina (UA). During the follow-up period the endpoint was reached by 28 patients.
RESULTS: A statistical relationship between the elevated level of GDF - 15 and the 5-year survival of these patients (χ2 = 4.75, p = 0.03) has been found. It was established that the level of the GDF-15 biomarker > 2350 pg/ml independently predicted the onset of adverse events with the sensitivity of 80% and the specificity of 60% (p = 0.006). To investigate the influence of the GDF-15 levels on mortality in the remote period, the Cox regression analysis was performed. It was revealed that the level of GDF-15 significantly predicted the onset of the primary endpoint within 5 years after ACS (p = 0.004).
CONCLUSIONS: The increased level of GDF-15, determined in the first 24 hours after development of ACS, is highly associated with the adverse outcome within 5 years after the event.
METHODS: Sections from diagnostic biopsies were assessed for oral epithelial dysplasia using the WHO grading system, and DNA ploidy analysis was performed using established methods. Patients reviewed for a minimum of 5 years who did not develop oral squamous cell carcinoma were classified as "non-transforming" cases. Patients that developed oral squamous cell carcinoma ≥ 6 months after the initial diagnostic biopsy were classified as having "malignant transformation."
RESULTS: Ninety cases were included in the study. Seventy cases yielded informative DNA ploidy results. Of these 70 cases, 31 progressed to cancer. Oral epithelial dysplasia grading and DNA ploidy status were both significantly associated with clinical outcome (P
