Abstract
Background
The coexistence of multiple standard modifiable risk factors (SMuRFs),classical and novel risk factors (RFs) for atherosclerotic cardiovascular disease (ASCVD) is common in the Middle East (ME). There is a paucity of data on the coexistence of these RFs in ME young women.
Aim
Comparing the prevalence and the statistical patterns of the SMuRFs, classical and novel RFs in target population.
Methods
In this case-control (1:2) study, consecutive young women aged 18–50 years were enrolled in 12 centers (July 2021 to October 2023). Prevalence and coexistence of 19 RFs were compared between cases with ASCVD and their controls. The RFs included SMuRFs (hypertension, type 2 diabetes, dyslipidemia, and cigarette smoking), other classical RF (obesity, family history of premature ASCVD, and physical inactivity), novel RFs and social determinants of health (health insurance, place of residence, depression, and level of education).
Results
The study included 627 subjects; 209 had ASCVD (median age 46 years, IQR 49–42 years) and 418 controls (median age 45 years, IQR 48–41 years). The presence of 1–2 RFs; (ASCVD: 63.2%, Control: 54.1%, p=0.037) and 3–4 RFs; (ASCVD: 27.8%, Control: 3.3%, p < 0.001) SMuRFs was more prevalent in women with ASCVD. Similarly, the presence of 4–5 RFs; (ASCVD: 40.7%, Control: 14.6%, p<0.001), and 6–7 (ASCVD: 10.5%, Control: 1%, p < 0.001). The classical RF were also significantly common in these women. The distribution of multiple novel RF was not statistically significant across both groups. Finally, regarding the socioeconomic RFs in women with ASCVDs, the presence of 1–2 RFs (ASCVD: 59.8%, Control: 76.1%, p < 0.001) was significantly less common while the presence of 3–4 RFs (ASCVD: 39.2%, Control: 21.8%, p < 0.001) was vastly more common.
Conclusion
An elevated rate of coexistence of classical RF in the case group, mainly socioeconomic and SMuRFs. By managing them primary and secondary ASCVDs prevention attained.
Introduction
Atherosclerosis is a chronic inflammatory disease involving multiple organs’ arterial beds, leading to formation of plaques that tend to progress with time and culminate in plague rupture, which causes acute myocardial infarction and stroke.Citation1–4 Notably, atherosclerotic cardiovascular disease (ASCVD) stands as the leading cause of global mortality.Citation5–7 Various risk factors contribute to ASCVD, categorized as, classical risk factors, which include obesity, physical activity, family history of premature ASCVD, and standard modifiable risk factors (SMuRFs) that encompass hypertension, type 2 diabetes, elevated serum low-density lipoprotein cholesterol (LDL-C) Levels, and smoking.Citation7,Citation8 Social determinants of health (SDH) include depression, urban living, low level of education, and lack of health insurance.Citation9,Citation10 Additionally, women of childbearing age can be subjected to a new subset of novel risk factors for ASCVD, which include preterm delivery, hypertensive disease of pregnancy, gestational diabetes, polycystic ovarian disease (PCOS), premature menopause, radiation for breast cancer, persistent weight gain after pregnancy,Citation11–14 While ASCVD typically affects the elderly population,Citation15,Citation16 nevertheless there is a rising recognition of the occurrence among young women, who constitute a unique demographic group despite their age, this cohort faces a distinct set of challenges in terms of diagnosis and management of AsCVD, which may differ from their elder counterparts.Citation17,Citation18 Understanding the interplay and coexistence of these risk factors is crucial for providing effective healthcare to this demographic.Citation19 Several studies worldwide and more so in the Middle East, evaluated the ASCVD RFs in adult populations.Citation20–25 However, there is a scarcity of studies that addressed the coexistence of these RFs, especially in SMuRFs. In this analysis of the atherosclerotic novel and classical risk factors in Young Women in the Middle East (ANCORS-YW), we report the prevalence and coexistence of 19 RFs in a cohort of Middle-Eastern young women.
Materials and Methods
Inclusion Criteria
The ANCORS-YW study consecutively enrolled married women aged 18–50 years diagnosed with ASCVD, and who had at least one pregnancy. Each patient with ASCVD was age-matched (±5 years) with two women not known to have ASCVD. ASCVD included acute coronary syndrome (ACS) (ST-segment elevation MI, non-ST-segment elevation MI, and unstable angina), and coronary artery disease (CAD) diagnosed by coronary computed tomographic angiography. It also included stroke and transient ischemic attack (diagnosed by a neurologist based on standard clinical and imaging criteria), extracranial carotid artery disease (diagnosed by the presence of atherosclerosis of the common or internal carotid artery evident by arterial Doppler, computed tomographic, or invasive angiography), and peripheral arterial disease (PAD) of the lower extremities (lower extremity ischemic pain and/or atherosclerosis evident by arterial Doppler, computed tomographic, or invasive angiography).
Study Design and Settings
A case-control, multicenter study was conducted in the period between August 2021 and October 2023 in 12 hospitals.
Data Collection
Using a standard case report from included anthropometric and demographic profiles, novel and classical RFs, and social determinants of health (SDOH); place of residence, level of education, depression, and presence of health insurance were documented in the patients and controls.
Sample Size Calculation
With a significance level of 0.05, a power of 80%, and assuming a frequency of any one of the studied variables to be 10%, we have calculated the minimum sample size required to detect a clinically significant association (odds ratio = 2) between ASCVD and any of the studied predictors, maintaining a 1:2 case-to-control ratio. The computed sample size was 209 cases and 418 controls.
Definitions of Classical RFs Including SMuRFs
Hypertension (HTN) was defined as repeated resting blood pressure (BP) measurements > 140/90 mm Hg, a prior diagnosis by a treating physician, or use of BP medications. Type 2 diabetes was defined as the presence of classical symptoms of hyperglycemia and casual plasma glucose ≥ 200 mg/dl, fasting plasma glucose ≥ 126 mg/dl; serum level of glycated hemoglobin ≥ 6.5 a prior diagnosis by a physician for use of antidiabetic medications. Dyslipidemia was defined as an elevated serum level of low-density lipoprotein cholesterol LDL-C > 70 mg/dl in those with ASCVD or T2D, while LDL > 116 mg/dl in those with no ASCVD nor T2D or use of lipid-lowering agents. Low serum level of high-density lipoprotein cholesterol (HDL-C) was defined as serum levels < 50 mg/dl. Body mass index was calculated by the standard formula (weight (kg)/height (m2)). Diagnosis of metabolic syndrome was confirmed by the presence of at least three of the following criteria: HTN, obesity (BMI ≥ 30 kg/m2), known case of DM, serum level of HDL-C < 50 mg/dl, and serum level of triglycerides > 150 mg/dl.
Definitions of Novel RFs
Preterm delivery was defined as a live delivery before 37 weeks and after 20 weeks of gestation. Hypertensive disorders during pregnancy (HDP) was defined as gestational HTN taking place after 20 weeks of gestation. Chronic HTN was defined as a preexisting disease before the 20th week of gestation, pre-eclampsia was defined as hypertension after the 20th week of gestation and proteinuria, and eclampsia defined as seizures not attributable to other causes in the presence of preeclampsia. Gestational DM was diagnosed if one or more of the following criteria aremet: fasting plasma glucose ≥ 126 mg/dl, 2-h plasma glucose ≥ 200 mg/dl following oral glucose load, or random plasma glucose ≥ 200 mg/dl in the presence of diabetes symptoms.
Polycystic ovary syndrome (PCOS) was defined by the presence of two clinical or biochemical hyperandrogenism features, ovulatory dysfunction, or polycystic ovaries. Premature menopause was defined as oligo-amenorrhea of more than 12 months associated with serial elevated gonadotropins on three occasions measured 4–6 weeks apart in women under the age of 40 years.
Depression was defined as prior diagnosis by a psychiatrist, or prescription of antidepressant medication.

A two-sided p-value of less than 0.05 was considered statistically significant.
Results
A total of 627 women were included in this study, with a mean age of 44.2 years. depicts the demographic and clinical profiles of the whole cohort. The mean BMI was 29.54 kg/m2. Most of the study participants were obese (43.4%) or overweight (33.5%). The most prevalent comorbidity was hypertension (37%). Regarding abnormalities in lipid profile, 31.9% of the females had elevated LDL and 19.8% of low HDL. The most common medication group was lipid lowering medications (39.1%) followed by beta-blockers (38.44%) and antiplatelets (36.0%).
Table 1 Demographics and Clinical Characteristic Among Middle Eastern Young Women
The distribution of classical (traditional), novel, and socioeconomic risk factors among the whole group of young women is demonstrated in . Among traditional risk factors, the presence of HTN (ASCVD: 56.46%, Control: 27.27%, p < 0.001), DM (ASCVD: 39.71%, Control: 11.72%, p < 0.001), smoking (ASCVD: 39.23%, Control: 24.16%, p < 0.001), elevated LDL levels (ASCVD: 54.55%, Control: 20.57%, p < 0.001), family history or premature ASCVD (ASCVD: 48.33%, Control: 23.44%, p < 0.001) were significantly more common in females with ASCVD. For novel risk factors, the prevalence of hypertensive disease of pregnancy (ASCVD: 30.62%, Control: 22.73%, p = 0.32), gestational DM (ASCVD: 16.75%, Control: 10.29%, p = 0.021), and pre-term delivery (ASCVD: 26.32%, Control: 16.75%, p = 0.005) was significantly more in ASVCD females. Regarding SDOH risk factors, low level of education (ASCVD: 74.64%, Control: 55.26%, p<0.001), and health insurance (ASCVD: 71.29%, Control: 56.94%, p < 0.001) were significantly more prevalent among females with ASCVD.
Table 2 The Distribution of Classical (Traditional), Novel, and Socioeconomic RF Among the Study Group with ASCVD and Their Controls
The coexistence of multiple risk factors in the study group is demonstrated in . The present study found that the presence of 1–2 (ASCVD: 63.2%, Control: 54.1%, p=0.037) and 3–4 (ASCVD: 27.8%, Control: 3.3%, p < 0.001) SMuRRFs was more prevalent in females with ASCVD. On contrast, the presence of 0 SMuRRFs was more prevalent in females without ASCVD (ASCVD: 9.1, Control: 42.6%, p < 0.001). In females with ASCVDs, the presence of 4–5 (ASCVD: 40.7%, Control: 14.6%, p<0.001), and 6–7 (ASCVD: 10.5%, Control: 1%, p < 0.001) classical risk factors were significantly more common, while the presence of 0 (ASCVD: 0%, Control: 5.02%, p=0.002) and 1–3 (ASCVD: 48.8%, Control: 79.4%, p < 0.001) classical risk factors were significantly less common. The distribution of multiple novel risk factors was not statistically significant across both groups.

Finally, regarding the socioeconomic risk factors in women with ASCVDs, the presence of 1–2 risk factors (ASCVD: 59.8%, Control: 76.1%, p < 0.001) was significantly less common, while the presence of 3–4 risk factors (ASCVD: 39.2%, Control: 21.8%, p < 0.001) was significantly more common.
A detailed breakdown of risk factor patterns in Middle Eastern young women with ASCVD and controls is demonstrated in Supplementary Table 1.
Discussion
The study’s findings provide crucial insights into the simultaneous presence of risk factors (RFs) and their correlation with ASCVD within this demographic. The research indicates that the co-occurrence of SMuRFs, socioeconomic RFs, and all classical RFs was notably higher in the ASCVD group compared to those without ASCVD. These findings align with prior studies, including one conducted in South Korea in 2019,Citation26 which also demonstrated a significant association between RFs and ASCVD. Similarly, a recent study published in 2023 found that a family history of smoking and obesity was linked to future cardiovascular disease.Citation27 By emphasizing the elevated prevalence of these risk factors, our study sheds light on the complex interplay between health-related behaviors, social determinants, and ASCVD risk among young women in the Middle Eastern region. This comprehension can guide targeted interventions aimed at mitigating the burden of ASCVD. This aligns with established evidence indicating the multifactorial nature of ASCVD etiology and underscores the importance of adopting a comprehensive approach to cardiovascular risk assessment and management. Furthermore, our study contributes to addressing existing gaps in the literature by specifically focusing on ASCVD risk factors in a population that has been historically underrepresented in cardiovascular research.
Despite its contributions, our study has several limitations that warrant consideration. Firstly, there is the potential for selection bias since participants were recruited from tertiary care centers, which may not be fully representative of the entire Middle Eastern population of young women with ASCVD, thus limiting the generalizability of our findings. Additionally, as is the case with all registries, the presence of difficulty to remember past medical history or lifestyle factors. Moreover, while our study primarily focused on classical and socioeconomic risk factors, we did not extensively investigate other potentially relevant factors such as dietary habits, environmental exposures, and genetic predispositions, which could have provided a more comprehensive understanding of ASCVD risk in studied population. Finally, the lack of significant differences in the coexistence of novel risk factors (eg, preterm delivery and breast cancer) between the ASCVD and control groups may suggest that these factors may not exert as significant an influence on ASCVD development in young women, at least within the scope of this study.
Our study’s findings offer critical perspectives into the nuanced landscape of risk factors for atherosclerotic cardiovascular disease (ASCVD) among young women in the Middle Eastern region. By delineating the varying contributions of different risk factors to ASCVD risk in this population, our research underscores the imperative for further investigation into the role of novel risk factors in ASCVD pathogenesis. Moreover, our findings prompt a reassessment of current preventive strategies, emphasizing the necessity for targeted interventions that prioritize modifiable risk factors and promote holistic cardiovascular health among young women in the Middle East. Catalyzing these transformative changes, our study holds the potential to propel significant advancements in cardiovascular care, foster interdisciplinary collaborations, and ultimately contribute to the realization of healthier, more equitable societies. Importantly, our study’s implications extend beyond research domains into clinical practice, public health policy, and societal well-being. By highlighting the prevalence of coexisting classical and socioeconomic risk factors, particularly emphasizing the significance of SMuRFs, our findings underscore the multifaceted nature of ASCVD in this demographic, emphasizing the importance of addressing both traditional cardiovascular risk factors and socioeconomic determinants in preventive and management strategies.
Conclusion
Huge challenges in preventing ASCVD in ME patient including Jordan, therefore tackling this burden is of utmost importance. Our study has demonstrated that in ME young women with ASCVD, had a high rate of coexistence of classical risk factors (SMuRFs in particular) and socioeconomic RFs. Insights into clustering patterns of risk factors are important for both the physician and the patient as it may guide management and prioritize the primary and secondary prevention strategies. Larger studies are needed to consolidate this data and evaluate the presence of non-traditional risk factors in this vulnerable population.
