Between-Sex Differences in Risk Factors for Cardiovascular Disease among Patients with Myocardial Infarction-A Systematic Review. J Clin Med 2023; 12:5163. [PMID: 37568564 PMCID: PMC10420061 DOI: 10.3390/jcm12155163] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 08/01/2023] [Accepted: 08/02/2023] [Indexed: 08/13/2023] Open
Abstract
Between-sex differences in the presentation, risk factors, management, and outcomes of acute myocardial infarction (MI) are well documented. However, as such differences are highly sensitive to cultural and social changes, there is a need to continuously re-evaluate the evidence. The present contemporary systematic review assesses the baseline characteristics of men and women presenting to secondary, tertiary, and quaternary centres with acute myocardial infarction (MI). Over 1.4 million participants from 18 studies, including primary prospective, cross sectional and retrospective observational studies, as well as secondary analysis of registry data are included in the study. The study showed that women were more likely than men to have a previous diagnosis of diabetes, hypertension, cerebrovascular disease, and heart failure. They also had lower odds of presenting with previous ischaemic heart disease and angina, dyslipidaemia, or a smoking history. Further work is necessary to understand the reasons for these differences, and the role that gender-specific risk factors may have in this context. Moreover, how these between-gender differences are implicated in management and outcomes also requires further work.

Abstract
Background Due to lack of contemporary data on the presentation, management, and mortality of acute coronary syndrome (ACS) admissions in Iran, in this prospective registry study, we aimed to evaluate the presentation, management, and mortality as the outcome of patients with ACS in Isfahan, Iran, 2001-2016 to address treatment and healthcare depletions. Methods Data of 62,276 patients admitted with the diagnosis of ACS from 2001 to 2016 prospectively were obtained by Surveillance Unit of Isfahan Cardiovascular Research Center, Isfahan, Iran, in 13 hospitals of Isfahan province. We evaluated data on presentation, management, and in-hospital and 28-day mortality. Results Nearly half of the patients ranged in age from 51 to 70 years (32050, 51.5%), which did not differ among ACS types (ST-segment myocardial infarction (STEMI): 53.9%; non-STEMI: 53.4%; unstable angina: 51.9%). In-hospital, anti-platelets use was high (84.9%). Thrombolytic were used in 48.1% of STEMI, 3.8% of non-STEMI, and 1.1% of unstable angina. Discharge medication rates were suboptimal. In-hospital and 28-day mortality were highest for STEMI (6.5 and 12.6%, respectively). Conclusions These data represent the large ACS registry in Iran. Data revealed the various presentations of ACS and demonstrated opportunities for improving ACS management by focusing on increasing use of recommended drugs especially after discharge due to suboptimal medical treatment in these patients. The high mortality rate needs to be taken into consideration in ACS patients.

J Tehran Heart Cent 2023; 18:94-101. [PMID: 37637281 PMCID: PMC10459340 DOI: 10.18502/jthc.v18i2.13318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Accepted: 03/16/2023] [Indexed: 08/29/2023] Open
Abstract
Background The present study aimed to determine the cost-effectiveness of ticagrelor compared with clopidogrel in Iranian patients with acute coronary syndrome (ACS). Methods A 1-year decision tree model combined with a 20-year Markov transition model was used to simulate the long-term cost and effectiveness of both ticagrelor and clopidogrel in Iran based on an Iranian payer's perspective. Clinical efficacy data were extracted from the PLATO trial and other published studies. Costs were estimated based on local prices in public sectors. Deterministic and probabilistic sensitivity analyses were used to test the robustness of base-case results over the uncertainties of model inputs. All calculations, analyses, and modeling were done in TreeAge 2011 and Microsoft Excel 2013. Results Compared with clopidogrel, the treatment of Iranian ACS patients with ticagrelor for 20 years resulted in an additional cost of US$ 2.39 in a hypothetical cohort of 1000 patients. However, ticagrelor led to 7.2 quality-adjusted life-years (QALYs) gained per 1000 hypothetical patients. Accordingly, the estimated incremental cost-effectiveness ratio for this analysis was US$ 332.032 per 1 QALY gained. Conclusion Ticagrelor was a cost-effective antiplatelet medicine compared with clopidogrel in Iranian patients with ACS. This could help Iran's policymakers to allocate resources more efficiently to ACS.

Abstract
BACKGROUND ST elevation myocardial infarction (STEMI) is an acute cardiac manifestation that requires immediate revascularization preferably through primary percutaneous coronary intervention (PCI). This study aims to describe gender stratified outcomes and epidemiological profile of STEMI patients undergoing treatment at a tertiary care hospital in Karachi, Pakistan. METHODS A 5-year, retrospective analysis of hospital records was undertaken on confirmed STEMI patients admitted between 2010 and 2014, undergoing primary PCI. Information was retrieved on demographic variables, risk factors, total ischemia time, door to balloon time, angiographic findings, and treatment strategy and in-hospital outcomes. RESULTS A total of 603 patients were available for analysis. Mean age of the participants was 58 ± 11 years, with 78.6% being males. The most common risk factors were hypertension (48.1%), diabetes (37%), and smoking (22.2%). Gender stratified analysis revealed poorer clinical presentation and prolonged ischemia time among women when compared to men (410 vs. 310 min, respectively). Total in-hospital mortality was 9.6% and was higher in women (19.3%), patients with non-anterior infarction (12%), Killip class >2 (39%), advanced age (14.6%), and multi-vessel disease (12%). CONCLUSION Our study describes the common risk factors and treatment outcomes for STEMI patients undergoing primary PCI at a tertiary care hospital in Karachi. In-hospital mortality and total ischemia time were higher among women compared to men in our study. Moreover, the risk profile, treatment related complications, and outcomes were poorer in women compared to men. We suggest further research to investigate the effect of prolonged ischemia time on long-term clinical outcomes.

Abstract
Background Due to the controversy over the effect of serum testosterone levels on coronary artery diseases, this survey explores the serum levels of free testosterone, luteinizing hormone, and follicle-stimulating hormone in candidates for coronary artery bypass graft compared with an age-matched control group and evaluates the associated factors in these participants.
Objective To determine the testosterone level in elective coronary artery bypass grafting participants. Materials and Methods In this cross-sectional study, all male patients aged > 40 yr as candidates for elective coronary artery bypass grafting, who were referred to the Afshar Hospital, Yazd, Iran, from March 2018 to March 2019, were included. In total, 100 men were enrolled (50 cases and 50 controls). Their serum levels of free and total testosterone, luteinizing hormone, and follicle-stimulating hormone were measured and the results were compared. Results The findings indicated a significant difference between the two groups in total and free testosterone (both p < 0.001); they were lower in the case group. There was also a significant difference in the total testosterone of the participants with diabetes mellitus compared with no-diabetic individuals (p = 0.007). Free testosterone of diabetic subjects taking insulin was lower compared with those taking no insulin (p = 0.04). There was also an association between the body mass index and free testosterone, left ventricular ejection fraction and total testosterone, and a significant and negative relation between the duration of hospital admissions and free testosterone (p < 0.05). Conclusion This study illustrates that participants with coronary artery disease bear a significantly low testosterone level in comparison with the healthy control group.

Abstract
BACKGROUND Hypertension is a major cause of noncommunicable diseases such as cardiovascular disease. Therefore, this study aimed to estimate the prevalence of hypertension in cardiovascular patients in Iran by meta-analysis. METHODS The search was carried out using authentic Persian and English keywords in national and international databases including IranMedex, Scientific Information Database (SID), Magiran, IranDoc, Medlib, ScienceDirect, PubMed , Scopus, Cochrane, Embase, Web of Science, and Google Scholar search engine without any time limitation until 2017. Heterogeneity of studies was assessed using I2 statistic . Data were analyzed using STATA 11.1. RESULTS In 66 reviewed studies with a sample of 111,406 participants, the prevalence of hypertension was 44% in Iranian patients with cardiovascular disease 67%(95%CI: 38%-49%) in women and 42% in men. The prevalence of systolic hypertension in cardiac patients was 25%, diastolic 20%, diabetes 27%, and overexposure 43%. The prevalence of hypertension was 44% in patients with coronary artery disease, 50% in myocardial infarction, 33% in aortic aneurysm, and 44% in cardiac failure. CONCLUSIONS Hypertension has a higher prevalence in women with cardiovascular disease than men, and it increases with age. Among patients with cardiovascular disease, myocardial infarction patients have the highest levels of hypertension. The prevalence of systolic hypertension in cardiac patients is higher than diastolic hypertension.

Abstract
Background Depression is a common condition in cardiac patients. We investigated the effect of cardiac rehabilitation on depressive symptoms as detected by Beck depression inventory II score (BDI) in patients who underwent percutaneous coronary intervention (PCI). Methods In this cohort, 95 patients met our criteria. Patients were then studied in two groups based on their participation in the rehabilitation program to rehabilitation (exposure) and the control (non-exposure) groups. The control group consisted of those who only participated in the introductory session and decided not to continue the program. Finally, demographic and clinical parameters as well as the BDI scores were compared between the study groups. Results Data of 35 patients who completed rehabilitation program was compared with 60 patients who did not. There was no significant difference between the study groups regarding the demographic and clinical variables, except for a higher frequency of family history for CAD in the control group (p < 0.001). The frequency of the patients with no or mild depression was significantly higher in the rehabilitation group than the controls (p = 0.02). There was also a significant increase in the BDI score of the control group and a significant decrease in the rehabilitation group (p < 0.001). After adjustment for confounders (family history and severity of CAD), not attending the rehabilitation program was a strong risk factor for depression (OR = 10.8, 95% CI: 1.3, 88.5; P = 0.027). Conclusion Overall, this study showed that not attending cardiac rehabilitation program following elective PCI was a risk factor for depression.

Abstract
In Iran, cardiovascular diseases are the most common causes of death. We aimed to perform a systematic review on the prevalence of acute myocardial infarction (AMI) in Iran based on Persian and English papers had been published from 1985 to 2015. Among 267 initially found articles, 142 were excluded; finally, a total number of 40 articles were found relevant which were reduced to 18. Smoking, hypertension, diabetes mellitus, and hypercholesterolemia were the most common risk factors for AMI. Premature MI prevalence was high in men, and smoking was the most common risk factor among young people. People in urban areas were more likely to experience AMI than rural people. The prevalence of AMI in Iran is high and has increased in recent years. Therefore, to restrain the rising trend of AMI, it is necessary to make the primary and secondary prevention efforts.

Abstract
Background: The data and determinants of mortality due to stroke in myocardial infarction (MI) patients are unknown. This study was conducted to evaluate the differences in risk factors for hospital mortality among MI patients with and without stroke history. Materials and Methods: This study was a retrospective, cohort study; 20,750 new patients with MI from April, 2012 to March, 2013 were followed up and their data were analyzed according to having or not having the stroke history. Stroke and MI were defined based on the World Health Organization's definition. The data were analyzed by logistic regression in STATA software. Results: Of the 20,750 studied patients, 4293 had stroke history. The prevalence of stroke in the studied population was derived 20.96% (confidence interval [CI] 95%: 20.13–21.24). Of the patients, 2537 (59.1%) had ST-elevation MI (STEMI). Mortality ratio in patients with and without stroke was obtained 18.8% and 10.3%, respectively. The prevalence of risk factors in MI patients with and without a stroke is various. The adjusted odds ratio of mortality in patients with stroke history was derived 7.02 (95% CI: 5.42–9) for chest pain resistant to treatment, 2.39 (95% CI: 1.97–2.9) for STEMI, 3.02 (95% CI: 2.5–3.64) for lack of thrombolytic therapy, 2.2 (95% CI: 1.66–2.91) for heart failure, and 2.17 (95% CI: 1.6–2.9) for ventricular tachycardia. Conclusion: With regards to the factors associated with mortality in this study, it is particularly necessary to control the mortality in MI patients with stroke history. More emphasis should be placed on the MI patients with the previous stroke over those without in the interventions developed for prevention and treatment, and for the prevention of avoidable mortalities.

Abstract
OBJECTIVES: Risk factors for heart failure (HF) have not yet been studied in myocardial infarction (MI) patients in Iran. This study was conducted to determine these risk factors. METHODS: In this nationwide, hospital-based, case-control study, the participants were all new MI patients hospitalized from April 2012 to March 2013 in Iran. The data on 1,691 new cases with HF (enrolled by census sampling) were compared with the data of 6,764 patients without HF as controls. We randomly selected four controls per one case, matched on the date at MI and HF diagnosis, according to incidence density sampling. Using conditional logistic regression models, odds ratios (ORs) with a 95% confidence interval (CI) were calculated to identify potential risk factors. RESULTS: The one-year in-hospital mortality rate was 18.2% in the cases and higher than in the controls (12.1%) (p<0.05). Significant risk factors for HF were: right bundle branch block (RBBB) (OR, 2.86; 95% CI, 1.95 to 4.19), stroke (OR, 2.00; 95% CI, 1.39 to 2.89), and coronary artery bypass grafting (CABG) (OR, 2.03; 95% CI, 1.34 to 3.09). Diabetes, hypertension, percutaneous coronary intervention (PCI), atrial fibrillation, ventricular tachycardia, and age were determined to be the factors significantly associated with HF incidence (p<0.05). The most important factor in women was diabetes (OR, 1.41; 95% CI, 1.05 to 1.88). Age, hypertension, PCI, CABG, and RBBB were the most important factors in men. CONCLUSIONS: Our findings may help to better identify and monitor the predictive risk factors for HF in MI patients. The pattern of risk factors was different in men and women.

Materials and Methods: This cross-sectional study was performed between April 2012 and March 2013. The data on the patients’ mortality due to MI in Isfahan were obtained from the MI National Registry. The international classification system (ICD10: I21-I22) was used to diagnose MI. The air quality indicators and environmental variables were used to measure the air pollution. Multilevel logistic regression in the Stata software was used to determine the factors associated with mortality in patients and odds ratios (ORs) were calculated. Results: Six hundred eleven patients with MI were studied during 1-year. 444 (72.2%) patients were male and the rest were female. 4.7% of the patients died due to MI. The mean age at MI incidence was 62.2 ± 13 years. Of the air pollution parameters, PM10 had the maximum mean concentration (49.113 ppm), followed by NOX, NO, NO2, CO, SO2, and O3. The adjusted OR of mortality was derived 2.07 (95% CI: 1.5-2.85) for right bundle branch block, 1.5 (95% CI: 1.3-1.7) for ST-segment elevation MI, 1.84 (95% CI: 1.13-3) for age, 1.06 (95% CI: 1.01-1.20) for CO, 1.1 (95% CI: 1.03-1.30) for O3, and 1.04 (95% CI: 1.01-1.4) for SO2, all of which were considered as the risk factors of mortality. However, OR of mortality was 0.79 for precipitation (95% CI: 0.74-0.84) and 0.52 for angioplasty (95% CI: 0.4-0.68) were considered as protective factors of mortality. The individual characteristics including age, history of MI in the immediate family, hypertension, and diabetes were significantly associated with mortality from MI. The indices of air pollution including SO2, CO, O3, and environmental factors such as the precipitation and temperature were the determinants of mortality in patients with MI. Conclusion: With regards to the factors associated with mortality from MI reported in this study, air pollution and environmental factors, in addition to the risk factors and predictive factors, should be particularly addressed to control the mortality from MI.

Abstract
Background: Regarding failure to establish the statistical presuppositions for analysis of the data by conventional approaches, hierarchical structure of the data as well as the effect of higher-level variables, this study was conducted to determine the factors independently associated with hospital mortality due to myocardial infarction (MI) in Iran using a multilevel analysis. Methods: This study was a national, hospital-based, and cross-sectional study. In this study, the data of 20750 new MI patients between April, 2012 and March, 2013 in Iran were used. The hospital mortality due to MI was considered as the dependent variable. The demographic data, clinical and behavioral risk factors at the individual level and environmental data were gathered. Multilevel logistic regression models with Stata software were used to analyze the data. Results: Within 1-year of study, the frequency (%) of hospital mortality within 30 days of admission was derived 2511 (12.1%) patients. The adjusted odds ratio (OR) of mortality with (95% confidence interval [CI]) was derived 2.07 (95% CI: 1.5–2.8) for right bundle branch block, 1.5 (95% CI: 1.3–1.7) for ST-segment elevation MI, 1.3 (95% CI: 1.1–1.4) for female gender, and 1.2 (95% CI: 1.1–1.3) for humidity, all of which were considered as risk factors of mortality. But, OR of mortality was 0.7 for precipitation (95% CI: 0.7–0.8) and 0.5 for angioplasty (95% CI: 0.4–0.6) were considered as protective factors of mortality. Conclusions: Individual risk factors had independent effects on the hospital mortality due to MI. Variables in the province level had no significant effect on the outcome of MI. Increasing access and quality to treatment could reduce the mortality due to MI.

Abstract
Introduction: Herbal medicines are traditionally prescribed to manage blood pressure.
Objectives: We aimed to evaluate effect of sour tea pill containing the herb’s extract versus captopril on the treatment of hypertension.
Patients and Methods: In our crossover clinical trial 20 patients were enrolled in the study and advised for life style modification then the participants were randomly divided into 2 groups. Sour tea pills was prescribed at a dose of 500 mg and captopril at a dose of 12.5 mg twice daily. In order to improve precision and final measurement, ambulatory blood pressure monitoring (ABPM) was performed both prior and after measuring the hypertension in 2 successive visits. After 6 weeks of therapy, the methods changed and 6 weeks later ABPM was performed three times (baseline, at end of the 6th and 12th week). The 2 groups were merged together before data analysis.
Results: Of the 20 patients, 13 (65%) were male and 7 (35%) were female. No significant difference of sex, age, and job was detected between 2 groups (P ≥ 0.05). Mean decreasing in systolic blood pressure was 7.75 ± 8.3 and 13.3 ± 16.1 mm Hg in the captopril and sour tea groups, respectively. Also, mean decline in diastolic blood pressure decreases was 2.15 ± 4.14 and 5.8 ± 7.8 mm Hg for captopril and sour tea groups, respectively. No side effect was observed in the sour tea pill group in the study.
Conclusion: According to the effect of sour tea pill on decreasing blood pressure, without giving priority over captopril, sour tea pill containing the herb’s extract can be prescribed as an adjuvant therapy for lowering the prescribed dosage of captopril.

Ahmadi A, Khaledifar A, Sajjadi H, Soori H. Relationship between risk factors and in-hospital mortality due to myocardial infarction by educational level: a national prospective study in Iran. Int J Equity Health 2014; 13:116. [PMID: 25428143 PMCID: PMC4251987 DOI: 10.1186/s12939-014-0116-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2014] [Accepted: 11/12/2014] [Indexed: 01/28/2023] Open
Abstract
Introduction Since no hospital-based, nationwide study has been yet conducted on the association between risk factors and in-hospital mortality due to myocardial infarction (MI) by educational level in Iran, the present study was conducted to investigate relationship between risk factors and in-hospital mortality due to MI by educational level. Methods In this nationwide hospital-based, prospective analysis, follow-up duration was from definite diagnosis of MI to death. The cohort of the patients was defined in view of the date at diagnosis, hospitalization and the date at discharge (recovery or in-hospital death due to MI). 20750 patients hospitalized for newly diagnosed MI between April, 2012 and March, 2013 comprised sample size. Totally, 2511 deaths due to MI were obtained. The data on education level (four-level) were collected based on years of schooling. To determine in-hospital mortality rate and the associated factors with mortality, seven statistical models were developed using Cox proportional hazards models. Results Of the studied patients, 9611 (6.1%) had no education. in-hospital mortality rate was 8.36 (95% CI: 7.81-8.9) in women and 6.12 (95% CI: 5.83-6.43) in men per 100 person-years. This rate was 5.56 in under 65-year-old patients and 8.37 in over 65-year-old patients. This rate in the patients with no, primary, high school, and academic education was respectively 8.11, 6.11, 4.85 and 5.81 per 100 person-years. Being woman, chest pain prior to arriving in hospital, lack of thrombolytic therapy, right bundle branch block, ventricular tachycardia, smoking and ST-segment elevation myocardial infarction were significantly associated with increased hazard ratio (HR) of death. The adjusted HR of mortality was 1.27 (95% CI: 1.06-1.52), 0.93 (95% CI: 0.77-1.13), 0.72 (95% CI: 0.57-0.91) and 0.82 (95% CI: 0.66-1.01) in the patients with respectively illiterate, primary, secondary and high school education compared to academic education. Conclusion A disparity was noted in post-MI mortality incidence in different educational levels in Iran. HR of death was higher in illiterate patients than in the patients with academic education. Identifying disparities per educational level could contribute to detecting the individuals at high risk, health promotion and care improvement by relevant planning and interventions in clinics and communities.
