Introduction: Acute myocardial infarction (AMI) is a leading cause of death and disability worldwide. Determining seasonal pattern of AMI may contribute to disease prevention and better treatment. Objective: The present study was conducted to investigate daily, monthly, and seasonal pattern for symptoms҆ onset in the patients with ST-segment elevation myocardial infarction (STEMI), and also other possible associated factors. Methods: This cross-sectional study was conducted on 777 patients diagnosed with STEMI admitted at the Imam Ali Cardiovascular Hospital affiliated with Kermanshah University of Medical Sciences (KUMS), Kermanshah province, Iran from March 2018 to February 2019. Data were collected using a checklist developed based on the study's objectives. Differences between subgroups were assessed using one-way analysis of variance (ANOVA) followed by Tukeys҆ post‐hoc test and Chi-Square test (or Fishers҆ exact test). Results: Out of 777 patients, 616 (79.3%) of them were male. Mean age of the patients was (mean±SD) equal to 60.93±12.86 years old. Occurrence of STEMI was most common in winter (38.4%), followed by autumn (27.8%), spring (22.9%), and summer (10.9%), respectively. Monthly occurrence of AMI was at the highest level in January (10.8%) and December (9.9%), and it was at the lowest level in July (4.9 %). Most patients were admitted on Fridays (15.8%) and Wednesdays (15.6%). Hypercholesterolemia, prior congestive heart failure (CHF), prior MI, prior stroke, prior atrial fibrillation (AF), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, total cholesterol, creatine phosphokinase (CPK), and creatine kinase myocardial band (CK-MB) were significantly associated with seasonal pattern of STEMI (p-value<0.05). Conclusions: Results of the present study on Iranian patients with STEMI revealed that AMI occurred more frequently on Wednesdays and Fridays and during winter from December to January compared to the other days of the week, months, and seasons.
Background: The present study aimed to investigate the psychological determinants of adherence to treatment among patients with cardiovascular diseases (CVDs) referring to Imam Ali Hospital in Kermanshah, Iran. Methods: This cross-sectional study was conducted on 227 patients (mean age=58.10, SD = 13.44) with CVDs, randomly selected amongst those admitted to Imam Ali cardiovascular center of Kermanshah in 2018. Data were collected through Meaning in Life Questionnaire (MLQ), the Jefferson Scale of Patient’s Perceptions of Physician Empathy (JSPPPE), the Illness Perception Questionnaire (IPQ), and Adherence to Treatment Questionnaire. The relationships between the criterion and predictor variables were assessed using Pearson correlation coefficient and linear regression (stepwise method) in IBM SPSS Statistics-23. Results: The adherence to treatment was associated with meaning in life (r=0.367), patients’ perceptions of physician empathy (r=0.218), and illness perception (r=-0.238), at the 0.01 level. Meaning in life, patient’s perceptions of physician empathy, and illness perception explained 18.6% of the variance in adherence to treatment. Meaning in life (beta=0.367 and P≤0.001) was the most influential predictor of adherence to treatment. Additionally, there was a significant difference in the score of adherence to treatment by gender (23.46±4.42 for female vs. 24.77±3.53 for male, P = 0.030). Conclusion: The patients’ perceptions of physician empathy, meaning in life, and illness perception were important factors to predict adherence to treatment in patients with CVDs. Gender was a significant predictor of the adherence to treatment.
Background: Despite the health benefits of smoking cessation on patients with cardiovascular diseases (CVDs), some resume smoking even after their discharge from hospital with acute coronary syndrome (ACS). Objectives: This study aimed to determine the predictors of smoking resumption after ACS in western Iran. Methods: This prospective cohort study was performed on 175 patients admitted to the Imam Ali Cardiovascular Center, Kermanshah, Iran, with a diagnosis of ACS from January 2018 to December 2018. Data were collected by a trained interviewer using a checklist developed based on the study objectives. Differences between groups were evaluated by independent t-test, chi-square, and Fisher’s exact tests. The relationship between smoking resumption and predicting variables was assessed using univariate and multivariate logistic regression models (Forward LR). Results: All participants were male with a mean age of 56.30 ± 8.91 (M ± SD) years. Three months post-discharge, 137 (78.3%) patients quit smoking, and 38 (21.7%) patients resumed it. The patients who resumed smoking were more likely to be divorced (20.6% vs. 0.7%), unemployed or retired (73.7% vs. 63.5%), have smokers in household (86.8% vs. 50.4%), and have history of depression (52.7% vs. 20.4%) (P-values < 0.05). The independent predictors of smoking resumption were divorce (OR 4.2, 95% CI: 1.31 - 19.01), having smokers in household (OR 12.08, 95% CI: 3.45 - 40.81), and history of depression (OR 12.16, 95% CI: 3.68 - 39.04). Conclusions: Divorce, having smokers in household, and history of depression were identified as the independent predictors of smoking resumption in ACS patients. Those who have these characteristics should be viewed as having a high risk of smoking relapse and be provided with more support to quit smoking.
Introduction Prosthetic valve dysfunction is a potentially critical complication of heart valve replacement. An easy and quickly applicable diagnostic procedure is required for recognizing the prosthetic valve dysfunction. The purpose of this study was to prospectively define the diagnostic value of D-dimer and INR level in predicting prosthetic valve dysfunction. Methods This cross-sectional study was performed in 70 patients suspected to have prosthetic valve dysfunction admitted to Imam Ali Hospital, affiliated with Kermanshah University of Medical Sciences (KUMS), Kermanshah Province, Iran. Cinefluoroscopy, as the gold standard diagnostic test, was used for the diagnosis of prosthetic valve dysfunction in enrolled patients. Two milliliters of blood from each patient were taken into a tube containing sodium citrate anticoagulant. To evaluate D-dimer, the cutoff value was set at 500 ng/ml. Also, to evaluate international normalized ratio (INR), the cutoff value was set at 2. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), and negative likelihood ratio (NLR) of the serum markers were used to describe predictive properties. Results Of 70 patients, 27 (38.6%) were male and 43 (61.4%) were female, and the mean age was 54.67±15.11 years (range, 18 to 80 years). Of 70 patients, 27 (38.6%) had prosthetic heart valve malfunction demonstrable by fluoroscopy, and 19 patients (27.1%) had D-dimer levels >500 ng/ml. Elevated D-dimer levels (>500 ng/ml) have been indicated to have sensitivity of 70.4%, and hence an NPV of 84.3%, specificity of 100%, PPV of 100%, NLR of 0.3, and the infinity value of PLR for predicting prosthetic valve dysfunction. There was a significant relationship between fluoroscopy and D-dimer test (P=0.001). A kappa coefficient value of 0.745 indicated a substantial agreement between D-dimer and fluoroscopy testing. Mixing test (combination of D-dimer and INR) showed to have 100% sensitivity, and hence a NPV of 69.8%, specificity of 69.8%, PPV of 51.8%, NLR of 1.41, and PLR of 1.44 for predicting prosthetic valve dysfunction. Conclusion D-dimer with moderate sensitivity and high specificity is an ideal marker for the diagnosis of prosthetic valve dysfunction in suspected patients. Enhanced plasma D-dimer level is not by itself diagnostic of a prosthetic valve dysfunction but may alert physicians to refer the patient for more detailed examination, preferably by fluoroscopy. Mixing test with 100% sensitivity can apply as a rule-out test.
Background: Doing percutaneous coronary intervention (PCI) in the first hours of myocardial infraction (MI) is effective in re-establishment of blood flow. Anticoagulation treatment should be prescribed in patients undergoing PCI to decrease the side effects of ischemia. The aim of this study is to determine the effect of heparin prescription after PCI on short-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). Materials: This randomized clinical trial study was conducted at Imam Ali cardiovascular center at Kermanshah university of medical science (KUMS), Iran. Between April 2019 to October 2019, 400 patients with STEMI which candidate to PCI were enrolled. Patients randomly divided in two groups: intervention group (received 5,000 units of heparin after PCI until first 24 hours, every 6 hours) and control group (did not receive heparin). Data were collected using a checklist developed based on the study's aims. Differences between groups were assessed using independent t-tests and chi-square (or Fisher exact tests).Result: Observed that, mean prothrombin time (PT) (13.30±1.60 vs. 12.21±1.15, p<0.001) and partial thromboplastin time (PTT) (35.30±3.08 vs. 34.41±3.01, p=0.003) were significantly higher in intervention group compared to control group. Thrombolysis in myocardial infarction (TIMI) flow grade 0/1 after primary PCI was significantly more frequently in control group (5.5% vs. 1.0%, p=0.034). The mean of ejection fraction (EF) after PCI (47.58±7.12 vs. 45.15±6.98, p<0.001) was significantly higher in intervention group. Intervention group had a statistically significant shorter length of hospital stay (4.71±1.03 vs. 6.12±1.10, p<0.001). There was higher incidence of re-vascularization (0% vs. 3.0%; p=0.013) and re-MI (0% vs. 2.5%; p=0.024) in the control group.Conclusion: Performing primary PCI with receiving heparin led to improve TIMI flow and consequently better EF. Receiving heparin is associated with lower risk of re-MI and re-vascularization.
