RESUMO
BACKGROUND: In 2019, a globally sustainable dietary pattern that primarily emphasizes the consumption of plant-based foods was proposed by the EAT-Lancet Commission. However, there is limited evidence regarding the association of this diet with coronary events. OBJECTIVES: To determine the association between the EAT-Lancet Reference Diet (ELD) and premature coronary artery disease (PCAD) risk and its severity. METHODS: This multi-center, case-control study was conducted within the framework of the Iran premature coronary artery disease (I-PAD). A total of 3185 participants aged under 70 years in women and 60 years in men were included. Cases were those whose coronary angiography showed stenosis ≥ 75% in at least one vessel or ≥ 50% in the left main artery (n = 2033), while the controls had normal angiography results (n = 1152). Dietary intake was assessed using a validated food frequency questionnaire. Logistic regression was utilized to examine the association between ELD and presence of PCAD. RESULTS: Compared with individuals in the first quartile, those in the highest quartile of ELD (OR = 0.29, 95% CI: 0.21, 0.39; P for trend < 0.001) and ELD calculated with minimum intake (OR = 0.39, 95% CI: 0.29, 0.52; P < 0.001) had lower risk of PCAD. Individuals in the highest quartile of adherence to the ELD and ELD with minimum intake had 78% and 72% lower risk of having severe PCAD compared with those in the lowest quartile, respectively. CONCLUSION: An inverse association was observed between adherence to the ELD and PCAD risk and its severity. Large-scale prospective cohort studies are required to confirm these findings.
RESUMO
OBJECTIVE: The cardioprotective effects of nuts are well established. However, the positive impacts of nuts in preventing CVD at a younger age, a condition known as premature coronary artery disease (PCAD), is still debated. Therefore, we aim to determine the association between nuts and PCAD occurrence and its severity in different Iranian ethnicities. DESIGN: This case-control study was conducted within the framework of the Iran-premature coronary artery disease (I-PAD) study, an ongoing multi-centric study on Iranian patients of different ethnicities. SETTING: This multi-centric case-control study was conducted in among 3253 persons under the age of 70 years in women and 60 years in men from different ethnicities in Iran. PARTICIPANTS: Information on nut consumption was collected using a validated FFQ. Subjects were selected from among the candidates for angiography. Cases were those whose coronary angiography showed stenosis of more than 75 % in at least one vessel or more than 50 % of the left main artery, while the control group participants had normal angiography results. RESULTS: In the crude model, compared to the first quartile, the highest quartile of nut consumption was significantly associated with a lower risk of PCAD (OR = 0·26, 95 % CI (0·21, 0·32); Pfor trend = 0·001). In the top quartile of nut intake, a substantial decrease in PCAD was observed after controlling for putative confounders (OR = 0·32; 95 % CI (0·24, 0·43); Pfor trend = 0·001). Additionally, a 75 % decrease in the risk of severe PCAD was observed in the participants in the highest quartile of nut intake. CONCLUSION: A significant inverse association was observed between nut intake and the risk and severity of PCAD in the Iranian population. Large-scale clinical trials are required to confirm these findings.

BACKGROUND: Population ageing is considered one of the biggest challenges facing the world, and the status of the elderly in society and their quality of life (QOL) have proved to be a concern in professional and scientific research circles. As a result, the current study sought to investigate the role of pain self-efficacy (PSE) as a moderator in the relationship between sense of coherence (SOC), spiritual well-being, and self-compassion with QOL in Iranian elderly with cardiovascular disease (CVD). METHOD: This was a correlational study of the path analysis type. The statistical population included all elderly people with CVD who were at least 60 years of age in Kermanshah Province, Iran, in 2022, of whom 298 (181 men and 117 women) were selected using convenience sampling and according to the inclusion and exclusion criteria. The participants answered questionnaires from the World Health Organization on QOL, Paloutzian and Ellison's spiritual well-being, Nicholas's PSE, Antonovsky's SOC, and Raes et al.'s self-compassion. RESULTS: The results of path analysis demonstrated that the hypothesized model of this study has a good fit in the studied sample. There were significant paths between SOC (ß = 0.39), spiritual well-being (ß = 0.13) and self-compassion (ß = 0.44) with PSE. Although there were significant paths between SOC (ß = 0.16) and self-compassion (ß = 0.31) with QOL, there was no significant path between spiritual well-being and QOL (ß = 0.06). Besides, there was a significant path between PSE and QOL (ß = 0.35). Finally, PSE was found to mediate the relationship of SOC, spiritual well-being and self-compassion with QOL. CONCLUSION: The results may provide psychotherapists and counselors working in this field of inquiry with advantageous information to choose or create a useful therapeutic method to work with the elderly with CVD. Meanwhile, other researchers are suggested to examine other variables which may serve a mediating role in the mentioned model.

Fetuin-A (AHSG) is a multifunctional secretory protein and acts as an ectopic valve and artery calcification inhibitor. We assessed the correlation between serum levels of Fetuin-A and both exon 6 (248 C/T) and exon 7 (256 C/G) mutations in patients with coronary artery calcification (CAC), mitral annular calcification (MAC), and aortic valve calcification (AVC). 184 patients and 184 healthy individuals as control group were included. The genetic variants of rs4917 and rs4918 for the AHSG gene were determined by PCR-RFLP and T-ARMS PCR techniques. Fetuin-A levels, fasting blood sugar (FBS), urea, creatinine, calcium phosphorus, and lipid profile were measured. Fetuin-A levels were remarkedly lower in individuals with AVC, MAC, and CAC comparing to the control group (p < 0.001). The CT + TT genotypes and the T allele (AHSG Thr248Met) were associated with the risk of calcification of heart valves and coronary artery by 1.31 and 1.27 times in the patient group, respectively. The frequency of CT genotype and T allele was considerably higher in the patient group comparing to the control group. Patients with T allele (CT + TT) had higher levels of FBS, urea, low-density lipoproteins (LDL)-C, phosphorus, systolic blood pressure (SBP), diastolic blood pressure (DBP) while decreased levels of triglyceride, high-density lipoproteins (HDL)-C, calcium and fetuin-A in comparison to control group. Additionally, there was a positive correlation between serum FBS, urea, creatinine, HDL-C, calcium with fetuin-A, and a negative correlation between phosphorous level, SBP, and DBP with fetuin-A. T allele in rs4917 Single nucleotide polymorphism (SNP) is the risk allele of calcification of heart valves and coronary arteries and fetuin-A levels correlates negatively with the occurrence of the disease.

OBJECTIVE: Mitral valve failure is one of the most common valvular heart diseases worldwide. Valve replacement and repair have an impact on the quality of life of patients. Therefore, the present study was conducted to compare the quality of life in patients with mitral valve replacement and those who underwent mitral valve repair. METHODS: In this cross-sectional study, we considered all cardiac patients with ischemic mitral insufficiency who underwent mitral valve repair and patients with a history of valve replacement in Imam Ali Hospital of Kermanshah between 2014 and 2020. Two Minnesota and general quality of life questionnaires along with a checklist for demographic variables were used for data collection. Data analysis was performed using SPSS version 21 software. RESULTS: The mean quality of life score based on the general quality of life scale in the valve repair group was 32.33 (SD = 2.29) and in the valve replacement group 32.89(SD = 2.60), (p = 0.917). Also, mean quality of life, as measured by the Minnesota MLHFQ was 60.89(SD = 17.67) in the valve repair group and 63.42 (SD = 12.13) in the valve replacement group (p = 0.308). The results showed that the average general quality of life was different in study groups regarding education. Tukey's post hoc test showed that the average general quality of life in illiterate people is significantly lower than in people with academic degrees (P-value = 0.001). CONCLUSION: The quality of life of the patients in both the valve repair and replacement groups was at an average level. There was no significant difference between the general quality of life and the Minnesota scales, suggesting that both tools can be effectively used to measure patients' quality of life. The study's findings can be valuable for monitoring patients, screening for conditions, and enhancing communication between doctors and patients.

Background: Matrix metalloproteinase (MMP) enzyme gene polymorphisms MMP-2-1575G/A and MMP-9-1562C/T promoter polymorphism, their serum levels, and activity are associated with aortic valve calcification (AVC). Materials and Methods: The synergistic link between the risk of AVC and the alleles T and A of MMP-9 and MMP-2 was investigated, respectively. Ninety-two cases with AVC and 92 healthy individuals from the west of Iran were included, and MMP- 2-1575G/A and MMP-9-1562C/T promoter polymorphisms were detected using PCR-RFLP. The serum levels and activity of MMP-2 and -9 were assessed using ELISA and gelatin zymography methods, respectively. In addition, serum biochemical markers, including FBS, urea and creatinine, cholesterol, triglyceride, HDL, LDL, calcium, phosphorus, and blood pressure: systolic blood pressure and diastolic blood pressure were measured. Results: Heart valve calcification disease was associated with a comparatively higher frequency of the A allele of the MMP2-1575 variation (p = 0.002). In addition, the frequency of T allele of the MMP9-1562 variant was higher than the control group (p = 0.007). Conclusion: MMP-2 and MMP-9 serum levels and activities were observed to be considerably higher in the experimental group than in the control group (p < 0.001). Patients are more susceptible to cardiovascular disease than the control group due to elevated serum levels and activity of MMP-2 and MMP-9.

Dairy products may affect hypertension (HTN) risk. The aim of this study was to examine the association between fermented and nonfermented dairy foods and HTN in a sample of premature coronary artery disease (PCAD) subjects. This cross-sectional study was performed on 1854 PCAD patients. A 110-item food frequency questionnaire was used to assess dietary intakes. HTN was considered if systolic blood pressure was 140 mmHg and higher and/or diastolic blood pressure was 90 mmHg and higher. The odds ratio of HTN across the quartiles of different types of dairy products was evaluated by binary logistic regression. The mean (SD) of dairy products consumption was 339.8 (223.5) g/day, of which 285.4 g/day was fermented dairy products. In the crude model, participants in the fourth quartile of fermented dairy products had lesser risk of HTN compared to the bottom quartile (OR = 0.70, 95% CI: 0.52, 0.96; p for trend = .058). However, after considering the possible confounders, the significance disappeared. Subjects in the top quartile of high-fat fermented dairy products had 34% lower risk for HTN compared to the bottom quartile (95% CI: 0.49, 0.88; p for trend < .001). Adjustment for potential risk factors weakened the association but remained significant (OR = 0.73, 95% CI: 0.53, 1.01; p for trend = .001). Nonsignificant relation was detected between low-fat fermented, low-fat nonfermented, and high-fat nonfermented dairy products and HTN. Moderate consumption of high-fat fermented dairy products, in a population with low consumption of dairy foods, might relate to reduced likelihood of HTN.
RESUMO
INTRODUCTION: Hypertension is widely known as a significant factor in the development of cardiovascular diseases. However, there is increasing interest in the potential link between low admission systolic blood pressure (SBP) and higher mortality rates. Therefore, this study aimed to investigate the relationship between admission SBP and the probability of one-year mortality in patients with ST-segment elevation myocardial infarction (STEMI). METHOD: This study, which used data from registries, focused on patients diagnosed with STEMI between July 2018 and December 2019. The patients were divided into three groups based on their admission SBP: normal (< 112 mm Hg), elevated (112-140 mm Hg), and hypertension (≥140 mm Hg), and were followed for one year. The researchers used Cox proportional models to analyze the data, which allowed them to estimate crude and fully adjusted hazard ratios, along with their corresponding 95% confidence intervals (HR, 95% CI). RESULTS: This study, which included 1159 patients with a mean age of 60.71±12.19, 914 (78.86%) were male, and 108 (9.32%) died within one year. Among the patients, 276 had a normal admission SBP, 338 had elevated SBP, and 545 had hypertension. Those with hypertension had a higher-risk profile, including factors such as hyperlipidemia, BMI, LDL levels, anterior myocardial infarction, and a higher prevalence of females. The crude and fully adjusted hazard ratios (HR) for the relationship between elevated admission SBP and mortality were calculated as 0.36 (95% CI: 0.23-0.56) and 0.43 (95% CI: 0.23-0.81), respectively. CONCLUSION: The study's findings indicate a connection between increased admission SBP and a decreased probability of one-year mortality among patients with STEMI. Unlike the general population, where there is a direct linear correlation between SBP and the risk of future cardiovascular events, this research demonstrates an inverse relationship between SBP and one-year mortality.
RESUMO
Introduction: Studies have linked secondhand smoke (SHS) exposure to adverse health effects. The high prevalence of heart disease necessitates the need for studies in this field. Therefore, the aim of the present study was to assess the exposure to SHS in cardiac patients. Method: This study is a cross-sectional descriptive study. A total of 430 patients who were referred to Imam Ali Hospital in Kermanshah, Iran, in 2020 were included in the study based on predetermined inclusion and exclusion criteria. The researchers collected and recorded demographic information, disease history, and exposure to secondhand smoke (SHS) through a digital questionnaire. Bivariate analysis was conducted using a chi-square test and an independent T-test, depending on the variable scale. Results: The results of the study showed that 237 patients were male (55.12 %) and 193 were female (44.8 %). The prevalence of exposure to secondhand smoke was 72.09 %. Notably, the highest rate of exposure to secondhand smoke was associated with 'exposure to tobacco smoke in public places' with a rate of 69.30 %. Additionally, it was observed that approximately 39.07 % of patients reported exposure to secondhand smoke in public places at least once a week. Conclusion: The present study has found that cardiac patients frequently experience secondhand smoking exposure, with public settings being the primary location of exposure. Implementing intervention strategies and enacting laws that prohibit smoking can effectively mitigate the negative impact of SHS exposure.
RESUMO
INTRODUCTION: Cigarette smoking is a preventable cause of cardiovascular morbidity and mortality. Despite the adverse effects of smoking, some studies have reported the term "smoker's paradox', meaning better outcomes in smokers following acute myocardial infarction. AIM: The aim of the present study was to evaluate the relationship between smoking status and one-year mortality in patients with ST-segment elevation myocardial infarction (STEMI). MATERIALS AND METHODS: This was a registry-based cohort study of STEMI patients from Imam-Ali hospital, Kermanshah, Iran. Consecutive STEMI patients (July 2016-October 2018) were stratified by smoking status and followed for one year. Cox proportional models were used to estimate crude, age-adjusted, and full-adjusted hazard ratios with 95% confidence intervals (HR, 95%CI). RESULTS: Of 1975 patients (mean age 60.1 years, 76.6% male) included in the study, 48.1% (n=951) were smokers (mean age 57.7 years, 94.7% male). Crude and age-adjusted HR (95% CI) for the associations of smoking and mortality were 0.67 (0.50-0.92) and 0.89 (0.65-1.22), respectively. After adjusting for age, sex, hypertension, diabetes, body-mass index, anterior wall myocardial infarction, creatine kinase-MB, glomerular filtration rate, left ventricular ejection fraction, low-density lipoprotein cholesterol, and hemoglobin, smoking was associated with increased risk of mortality: HR (95% CI: 1.56 (1.04-2.35). CONCLUSIONS: In our study, smoking was associated with an increased risk of mortality. Although the smokers had a better outcome, this would be reversed after controlling for age and the other STEMI associated factors.

BACKGROUND: The precise impact of sex difference on in-hospital mortality in ST-elevation myocardial infarction (STEMI) patients are unclear, and the studies are no longer consistent. Therefore, we sought to evaluate the impact of sex differences in a cohort of STEMI patients. METHODS: We analyzed the data of 2647 STEMI patients enrolled in the Kermanshah STEMI Cohort from July 2017 to May 2020. To accurately clarify the relationship between sex and hospital mortality, propensity score matching (PSM) and causal mediation analysis was applied to the selected confounder and identified intermediate variables, respectively. RESULTS: Before matching, the two groups differed on almost every baseline variable and in-hospital death. After matching with 30 selected variables, 574 male and female matched pairs were significantly different only for five baseline variables and women were no longer at greater risk of in-hospital mortality (10.63% vs. 9.76%, p = 0.626). Among the suspected mediating variables, creatinine clearance (CLCR) alone accounts for 74% (0.665/0.895) of the total effect equal to 0.895(95% CI: 0.464-1.332). In this milieu, the relationship between sex and in-hospital death was no longer significant and reversed -0.233(95% CI: -0.623-0.068), which shows the full mediating role of CLCR. CONCLUSION: Our research could help address sex disparities in STEMI mortality and provide a consequence. Moreover, CLCR alone can fully explain this relationship, which can highlight the importance of CLCR in predicting the short-term outcomes of STEMI patients and provide a useful indicator for clinicians.

Background and Aims: Low- and middle-income nations account for at least three-quarters of cardiovascular disease deaths worldwide. This study aimed to obtain real knowledge about ST segment elevation myocardial infarction (STEMI) patients and provide the context for developing a principles for care quality improvement. Method: This cross-sectional study was conducted from July 2018 through December 2019. The study sample consisted of1169 eligible patients based on inclusion criteria. The data were collected using the standard EROP and three specialized, trained questionnaires. The collected data were checked by the quality control officer and analyzed using Stata Version 14. Results: Patient baseline characteristics showed that body mass index, low-density lipoprotein, high-density lipoprotein, total cholesterol, and triglyceride levels were higher in women. Also, females recorded a considerable history of diabetes mellitus, hypertension, and hypercholesterolemia compared to men. The results also showed that most men were smokers (46.80%). Aspirin (94.27%), statins (91.48%), and clopidogrel (90.68%) were the common medications used at hospital discharge for patients. Conclusion: The present study suggests that identifying and managing modifiable risk factors can improve cardiovascular disease outcomes. Also, considering the early identification of STEMI patients with new therapies can effectively decrease the rate of cardiovascular disease and its attributed health outcomes.
RESUMO
BACKGROUND: Obesity is strongly associated with increased cardiovascular diseases (CVD) and cardiovascular risk factors, such as diabetes mellitus, hypertension, and dyslipidemia. However, numerous studies have suggested the existence of an "obesity paradox" in which overweight and mildly obese patients often exhibit a better outcome than their leaner counterparts. Therefore, this study aimed to characterize the association between BMI and in-hospital and one-year outcomes. METHOD: This hospital-based research was conducted as a part of the Kermanshah STEMI Registry. Following the application of inclusion criteria, a total of 2,397 STEMI patients were evaluated. The data were collected using a standardized case report developed by the European Observational Registry Program (EORP). Body mass index (BMI) (kg/m2) was classified into underweight (<18.5), normal weight (18.5-24.9), overweight (25-29.9), class I/mild obese (30-34.9), and class II/extreme obese (≥35) categories. The independent predictors of the in-hospital and one-year outcomes were assessed using multivariable logistic regression models. RESULTS: Out of the 2397 patients, 43 (1.79%) were underweight, 934 (38.97%) were normal, 1038 (43.30%) were overweight, 322 (13.43%) were class I obese, and 60 (2.50%) were class II obese. The results of the crude analysis showed that class I obesity was protective against CV death (OR 0.50; 95% CI 0.30-0.84), MACE3 (MI, stroke, and death) (OR 0.47; 95% CI 0.29-0.76), and MACE5 (MACE3 plus unstable angina and heart failure) (OR 0.59; 95% CI 0.44-0.79). CONCLUSIONS: Multivariate adjustment eliminated the protective effect of class I obesity against death and MACE events. Therefore, it is possible that this protective effect does not exist and instead reflects the impact of confounding variables such as age.
RESUMO
Introduction: Few studies have investigated the characteristics of patients with ST elevation myocardial infarction (STEMI) according to age and sex in Iran. This study aims to investigate the risk factors profile, treatment, and mortality of STEMI based on age and sex. Methods: From 10th June 2016 to December 2019 a total of 2816, STEMI patients referred to the Imam Ali heart center of Kermanshah were included in the study. Profile of the risk factors, epidemiology, treatment and 30- day mortality for all cases in the age categories of 18-49, 50-64, and≥65 years were studied. Results: There were 1256 (44.6%) middle-aged STEMI patients, and 2181 (77.45%) were male. The elderly had a longer median door-to-balloon and symptom-to-balloon time and received less primary PCI. In the absence of primary PCI, the rate of 30-day mortality in women was higher than in men, and the mortality rate increased with age. The risk of death in middle-aged women was higher than that of men. Also, in the middle-aged group, after multivariable adjustment, previous bypass surgery, diabetes, and Killip class≥2 was associated with significant increase in the risk of death. Conclusion: The present study showed that young people with STEMI had a high risk of heart failure and anterior infarction compared to the older age groups. Women had more risk factors for STEMI and a higher mortality rate than men. Therefore, there is a need to educate young age groups and women to modify their lifestyles and intervene in the risk factors of heart diseases.
RESUMO
BACKGROUND: Little is known about the predictors of left ventricular ejection fraction (LVEF) -an important predictor of mortality- after primary percutaneous coronary intervention (PCI) in low- and middle-income countries. METHODS: In a prospective cohort study at Imam Ali hospital, Kermanshah, Iran, we enrolled consecutive ST-elevation myocardial infarction (STEMI) patients treated with primary PCI (2016-2018) and followed them up to one year. LVEF levels were measured by echocardiography, at baseline and one-year follow-up. Determinants of preserved/improved LVEF were assessed using multi-variable logistic regression models. RESULTS: Of 803 patients (mean age 58.53±11.7 years, 20.5% women), baseline LVEF levels of ≤35% were reported in 44%, 35- 50% in 40%, and ≥50% in 16% of patients. The mean ± SD of LVEF increased from 38.13%±9.2% at baseline to 41.49%±9.5% at follow-up. LVEF was preserved/improved in 629 (78.3%) patients. Adjusted ORs (95% CIs) for predictors of preserved/improved LVEF showed positive associations with creatinine clearance, 1.01 (1.00-1.02) and adherence to clopidogrel, 2.01 (1.33-3.02); and inverse associations with history of myocardial infarction (MI), 0.44 (0.25-0.78); creatine kinase MB (CK-MB), 0.997 (0.996- 0.999); door-balloon time (3rd vs. 1st tertile), 0.62 (0.39-0.98); number of diseased vessels (2 and 3 vs. 1: 0.63 (0.41-0.99) and 0.58 (0.36-0.93), respectively); and baseline LVEF (35-50% and ≥50% vs. ≤35%: 0.45 (0.28-0.71) and 0.19 (0.11-0.34), respectively). CONCLUSION: Adherence to clopidogrel, short door-balloon time, high creatinine clearance, and lower baseline LVEF were associated with preserved/improved LVEF, while history of MI, high CK-MB, and multi-vessel disease were predictors of reduced LVEF. Long-term drug adherence should be considered for LVEF improvement in low- and middle-income countries.

INTRODUCTION: This study was aimed to evaluate the sex-based differences in baseline characteristics and one-year outcomes of men and women undergoing mitral valve repair for infective endocarditis. METHODS: This cross-sectional study was performed at Imam Ali Hospital affiliated with the Kermanshah University of Medical Science. From March 21, 2014, to October 21, 2021, all patients who underwent mitral valve repair for infective endocarditis were enrolled in this study. Data were obtained using a checklist developed based on the study's objectives. Independent samples t-tests, paired samples t-tests, and chi-squared test (or Fisher's exact test) were used to assess the differences between subgroups. RESULTS: Of 75 patients, 26 were women (34.7%) and 49 were men (65.3%). Women were more likely to have diabetes mellitus (20.4% vs. 57.7%, P=0.0001), hypertension (49% vs. 80.8%, P=0.007), and hypercholesterolemia (55.1% vs. 80.8%, P=0.027). Conversely, men were more likely to have a history of smoking (38.8% vs. 7.7%, P=0.004). After one year, women had significantly higher mortality (0% vs. 7.7%, P=0.049), major adverse cardiac and cerebrovascular events (51.0 vs. 76.9, P=0.029), mitral valve reoperation (8.1% vs. 34.6%, P=0.003), and treatment failure (30.6% vs. 61.5%, P=0.009) rates than men. CONCLUSION: Mortality, major adverse cardiac and cerebrovascular events, mitral valve reoperation, and treatment failure rates were higher in women than in men. The worse outcomes in women may be explained by their more adverse clinical risk profile.

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. METHOD: 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.
RESUMO
Background: Ultra-processed foods (UPF) consumption may affect the risk of PCAD through affecting cardio metabolic risk factors. This study aimed to evaluate the association between UPFs consumption and premature coronary artery disease (PCAD). Methods: A case-control study was conducted on 2,354 Iranian adults (≥ 19 years). Dietary intake was assessed using a validated 110-item food frequency questionnaire (FFQ) and foods were classified based on the NOVA system, which groups all foods according to the nature, extent and purposes of the industrial processes they undergo. PCAD was defined as having an stenosis of at least single coronary artery equal and above 75% or left main coronary of equal or more than 50% in women less than 70 and men less than 60 years, determined by angiography. The odds of PCAD across the tertiles of UPFs consumption were assessed by binary logistic regression. Results: After adjustment for potential confounders, participants in the top tertile of UPFs were twice as likely to have PCAD compared with those in the bottom tertile (OR: 2.52; 95% CI: 1.97-3.23). Moreover, those in the highest tertile of the UPFs consumption had more than two times higher risk for having severe PCAD than those in the first tertile (OR: 2.64; 95% CI: 2.16-3.22). In addition, there was a significant upward trend in PCAD risk and PCAD severity as tertiles increased (P-trend < 0.001 for all models). Conclusion: Higher consumption of UPFs was related to increased risk of PCAD and higher chance of having severe PCAD in Iranian adults. Although, future cohort studies are needed to confirm the results of this study, these findings indicated the necessity of reducing UPFs intake.
RESUMO
Background: Identifying the long-term predictors of recurrent cardiovascular events may help improve the quality of care and prevent subsequent events. We aimed to investigate the predictors of 1-year major cardiovascular events (MACE) in patients discharged after ST-elevation myocardial infarction (STEMI) in a tertiary hospital in Iran. Methods: This registry-based cohort study included consecutive STEMI patients between 2016 and 2019 in Imam-Ali Hospital, Kermanshah, Iran. All patients discharged alive from STEMI hospitalization were followed up for 1 year for MACE, consisting of all-cause mortality, nonfatal MI, and nonfatal stroke. We estimated the hazard ratio (HR) and the 95% confidence interval (95% CI) using Cox proportional-hazard models to evaluate potential predictors, including demographic characteristics, medical history, cardiovascular risk factors, laboratory tests, reperfusion therapy, and medications. Results: During 2187.2 person-years, 21 patients were lost to follow-up (success rate =99.1%). Of 2274 post-discharge STEMI patients (mean age =60.26 y; 21.9% female), 151 (6.6%) experienced MACE, including, all-cause mortality (n=115, 5.1%), nonfatal MI (n=20, 0.9%), and nonfatal stroke (n=16, 0.7%). Independent predictors of MACE were age (HR:1.02; 95% CI: 1.00-1.04), no education vs ≥12 years of formal schooling (HR: 2.07; 95% CI: 1.17-3.67), stroke history (HR: 2.37; 95% CI: 1.48-3.81), the glomerular filtration rate (HR: 0.98; 95% CI: 0.97-1.00), the body mass index (HR: 0.94; 95% CI:, 0.89-0.99), peak creatine kinase-MB (HR: 1.00; 95% CI: 1.00-1.002), thrombolysis vs primary percutaneous coronary intervention (HR: 1.85; 95% CI: 1.21-2.81), and left ventricular ejection fraction <35% vs ≥50% (HR: 2.82; 95% CI: 1.46-5.47). Conclusion: Age, education, stroke history, the glomerular filtration rate, the body mass index, peak creatine kinase-MB, reperfusion therapy, and left ventricular function can be independently associated with 1-year MACE.
RESUMO
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.
