Predictors of In-hospital Mortality after Primary Percutaneous Coronary Intervention for ST-segment Elevation Myocardial Infarction
Introduction: Treatment of myocardial infarction (MI) has been successfully developed, especially after introducing primary percutaneous coronary intervention (PPCI) as it nowadays is the recommended treatment for ST-segment elevation myocardial infarction (STEMI). Objective: This study aimed to evaluate the in-hospital mortality of STEMI patients treated with PPCI according to gender and other likely risk factors. Methods: This cross-sectional study presents a part of the results of a single-center registry in Imam Ali cardiovascular center affiliated to Kermanshah University of medical science (KUMS). From June 2016 to December 2017, 731 consecutive patients undergoing PPCI registered. Data were collected using a case report form developed by European Observational Registry Program (EORP). The relationship between in-hospital mortality and predicting variables was assessed using the Chi-square test, t-test, and univariate and multivariate logistic regression models (Forward LR). Results: Totally, 155 patients (approximately 21%) were female. The mean age of women and men was 65.2 and 57.5, respectively (p=0.001). There were differences between women and men in hypertension (58.1% vs. 30.4%, respectively, p=0.001), diabetes mellitus (26.5% vs. 14.9%; p=0.001), hypercholesterolemia (37.4% vs. 18.6%; p=0.001), and history of prior congestive heart failure (5.2% vs. 2.0%; p=0.016). Although more men were current smokers (58.7% (men) vs. 15.5% (women); p=0.001). Women had a significantly greater incidence of multi-vessel disease, thrombolysis in myocardial infarction (TIMI) flow grade of 0/1 before PPCI, and longer symptom-to-balloon time. In-hospital mortality was higher in women than in men (5.2% vs. 1.9%; p=0.024). Multivariate analysis identified age ≥ 60 years, Killip class≥ II, and post-procedural TIMI flow grade < 3, but not female sex, as independent predictors of in-hospital mortality. Conclusion: In-hospital mortality after PPCI in women was higher than men, though this difference was likely due to the severe clinical profile in women. Also, female gender was not identified as an independent predictor of death
Sex Differences in Risk Factors Profile and Angiographic Pattern of the Patients Undergoing Coronary Angiography
Introduction: Coronary artery disease (CAD) is a costly problem and its presentations and risk factors may differ by sex. Objective: This study aimed to evaluate the risk factors profile and angiographic pattern of the patients undergoing coronary angiography, according to their gender. Methods: This cross-sectional study was conducted on 741 patients who were referred for coronary angiography from March to August 2018 at Imam Ali cardiovascular center, western Iran. Using a checklist, we collected the demographic, clinical, biochemical, and lab parameters and angiographic findings in these patients. Also, differences between groups were compared using Chi-square and independent t-tests. Results: Women were different from men in terms of the prevalence of hypertension (71.7% vs. 45.3%), diabetes mellitus (34.9% vs. 17.8%), and hypercholesterolemia (26.4% vs. 17.1%). Whereas, men were more likely to be smoker (28.7% vs. 0%) and obese (42.09±16.68 vs. 29.12±4.72). Total Cholesterol and Triglycerides were higher in women compared to men, which were statistically significant. Glucose plasma was significantly higher in women compared to men (p=0.01). Both atherogenic (low-density lipoprotein (LDL)) and protective (high-density lipoprotein (HDL)) cholesterol were higher in women than men. Women were more likely to take antiplatelet (i.e. Aspirin) and antihypertensive therapies (i.e. beta-Blocker, angiotensin receptor blockers (ARBs), and angiotensin converting enzyme (ACE) inhibitors) than men. Also, it was shown that, Men were more likely to have two-vessel disease (p=0.041) and three-vessel disease (P=0.013) compared to women. Disease in the right coronary artery (RCA) (28.9% vs. 14.4%), circumflex (LCx) (26.0% vs. 15.3%), and left anterior descending (LAD) (37.8% vs. 26.4%) was more plausible to occur in men compared to women (p≤0.05). Conclusion: Access and use of health care programs are needed to control CAD risk factors. The findings of the current study showed the significance of gender in the extent of coronary artery blockages

The effect of heparin after primary percutaneous coronary intervention on short-term clinical outcomes in patients with ST-segment elevation myocardial infarction
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
Effect of Smoking Cessation on Left Ventricular Ejection Fraction after Acute ST Elevation Myocardial Infarction
BACKGROUND: Acute Myocardial Infarction (AMI) is the leading cause of global mortality. Moreover, Left Ventricular Ejection Fraction (LVEF) is the most important predictor of post-AMI mortality. Thus, the present study aimed to investigate the relationship between smoking cessation and LVEF following one year from the STEMI.CASE REPORT: The present study was a part of the Kermanshah STEMI Registry and included 825 smokers admitted to Imam Ali Hospital, Kermanshah, Iran, with AMI during a 2-year study period. Data collection was performed using the standardized case report form by the European Observational Registry Program (EORP). Moreover, multiple logistic regression was used to compare LVEF between the patients who had quit smoking post-AMI and those who were still smokers after one year. Also, one-to-one Propensity Score Matching (PSM) was used to reduce the assessment error and selection bias, increase the result accuracy, and minimize the effects of confounders on the LVEF-smoking relationship.Results: Following one year after AMI, 219 (26.55%) patients had quit smoking, while 606 (73.45%) still smoked. Using the PSM, a total of 168 ex-smokers were matched to 168 current smokers. Moreover, it was shown that LVEF was higher in current smokers compared to ex-smokers. However, the difference was not significant. Also, multiple logistic regression showed that the Odds Ratio (OR) of LVEF reduction was insignificantly higher in ex-smokers (OR=1.13; 95% CI: 0.98-1.29) compared to current smokers. Multivariate regression analysis found similar results even after the application of PSM (OR 1.02; 95% CI: 0.82-1.22).CONCLUSIONS: Given the low rate of smoking cessation after MI, physicians are recommended to ask about the smoking status of MI patients at each office visit or re-admission and strongly recommend quitting smoking
Incidence of Captopril–Induced Cough in Newly Diagnosed Hypertensive Patients: Incidence in an Outpatient Medical Clinic Population in Iran in 2011-2012
Introduction: In patients with uncomplicated primary hypertension (HTN), angiotensin converting enzyme inhibitors (ACEIs) are considered as monotherapy. In some studies, cough was not related to age, sex, underlying disease, or drug dosage. However, in previous studies, the incidence of cough was greater in females than males. The aim of this study is to determine the incidence of captopril-induced cough in patients with HTN and to evaluate some associated parameters such as sex and age.
Materials and Methods: In this cross-sectional epidemiologic study, 877 patients with new onset HTN, referring to our outpatient clinic, were assessed and underwent treatment by captopril as first-line medical treatment. All patients were enrolled in four different age groups (55 years old) and comparison was made between the groups.
Results: The overall incidence of captopril-induced cough was 15.5%, with a significant difference between females and males and obviously a higher rate in females (P=0.017). In addition, cough was significantly more common in females than males in 36- to 45-year-old group (46.42% vs. 24.71%). The incidence of cough after treatment with captopril decreased by increasing age of patients and this reduction in both male and female patients was statistically significant (
Investigating the Radiation Dose Received by the Heart and Its Electrocardiographic Changes after Three-dimensional Conformal Radiation Therapy in Patients with Left Breast Cancer
Background and Objective: Breast cancer is one of the most common cancers and the fifth leading cause of cancer deaths in Iran. The present study aimed to investigate the absorbed dose received by the heart and its relationship with cardiac complications in radiotherapy of patients with left breast cancer using a three-dimensional conformal radiotherapy technique.
Materials and Methods: A total of 181 women with left breast cancer who received radiotherapy after surgery were included in the study. Dosimetric parameters were obtained using dose-volume histograms for the heart, whole lung, left lung, and clinical target volume. Electrocardiography tests were performed for all patients before and one year after the radiotherapy.
Results: The mean doses of heart, left lung, whole lung, and clinical target volume were 6.3±3.1, 13.3±4.5, 6.9±3.7, and 47.3±6.4 Gray (Gy), respectively. A significant reduction in T-wave amplitude was observed in 57% of patients three months after radiotherapy. T-wave amplitude decreased from 3.03±0.92 mm to 1.56±0.83 mm. The reduction in the T-wave amplitude displayed a significant relationship with the mean dose of the heart (β = 2.653; P= 0.019).
Conclusion: In women with left-sided breast cancer, cardiac complications are frequent, for which electrocardiographic tests can be used for cardiac evaluation after radiotherapy. Based on the obtained results, the most frequent side effect caused by radiotherapy in these patients was an abnormality in T-wav
