Introduction: Cancer antigen 125 (CA-125) is a tumor marker of ovarian cancer, which has shown to be increased in different cardiovascular diseases. Although the prognostic role of CA-125 in heart failure and coronary heart disease is well-established, there is little known about its role in acute myocardial infarction (AMI). In this study we aimed to evaluate the serum levels of CA-125 in patients with AMI and its prognostic role in evaluating the in-hospital outcome of AMI. Methods: We evaluated 120 male patients with AMI and 120 male normal subjects. CA-125 levels were measured upon the patient’s admission to hospital. The in-hospital major adverse cardiac events (MACE) and its predictors were also recorded for AMI patients. Results: CA-125 levels were significantly higher in AMI patients compared to normal subjects (7.99±6.83 vs. 5.70±4.62, P = 0.003). We found significant positive correlations between CA-125 levels with creatine kinase-MB (CKMB) (r=0.621, P < 0.001) and CTnI (r=0.491, P < 0.001). The in-hospital MACE was observed in 19 cases (15.8%). Patients with MACE had significantly higher value of CA-125, CKMB and CTnI and lower LVEF compared to patients without MACE. CKMB (OR=0.967, 95% CI [0.943-0.991], P = 0.007) and CA-125 levels (OR=0.821, 95% CI [0.688-0.979], P = 0.02) were independent predictors of MACE. Conclusion: Serum CA-125 levels are significantly higher in male patients with AMI compared to normal subjects and have a significant role in predicting in-hospital MACE after AMI. In patients with higher CA-125 more aggressive treatment and close observation should be performed in order to reduce the possible adverse outcomes.
Objectives: The occurrence of arrhythmias after myocardial infarction is associated with an increased risk of mortality. The purpose of this study was to investigate tachyarrhythmias after streptokinase therapy in myocardial infarction patients. Methods: This study was a case-control study. Among 262 patients with myocardial infarction who received streptokinase, 168 patients with ventricular tachyarrhythmia, ventricular fibrillation, or both (case group), and 94 patients without arrhythmia (control group) were selected. Their clinical information were collected by questionnaire. Data were analyzed using SPSS 20 software through chi-square test and Wilcoxon rank-sum. Results: There was no relationship between demographic variables or electrocardiogram changes and the type of arrhythmia in 168 participants in the group 1 (p > 0.05). However, there was a significant relationship between age (p = 0.04), sex (p = 0.049), diabetes (p = 0.039), hypertension (p = 0.037), history of beta-blocker use (p = 0.028), history of aspirin use (p = 0.023), number of the leads involved (p = 0.023) and occurrence of arrhythmia among the participants in the group 2. Conclusions: According to the findings of this study, patients with myocardial infarction who need to receive thrombolysis and who have any of the following conditions should be monitored by the health care staff to prevent development of ventricular tachyarrhythmias: old age, male gender, history of diabetes mellitus, hypertension or more lead involvement in their electrocardiogram.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
