Association of depression with coronary artery disease and QTc interval prolongation in women with chest pain: data from the KoRean wOmen'S chest pain rEgistry (KoROSE) study

Differences in coronary angiographic findings and outcomes between men and postmenopausal women with stable chest pain

BACKGROUND

Despite the significant increase in cardiovascular events in women after menopause, studies comparing postmenopausal women and men are scarce.

METHODS

We analyzed data from a nationwide, multicenter, prospective registry and enrolled 2412 patients with stable chest pain who underwent elective coronary angiography. Binary coronary artery disease (b-CAD) was defined as the ≥50% stenosis of epicardial coronary arteries, including the left main coronary artery.

RESULTS

Compared with the men, postmenopausal women were older (66.6 ± 8.5 vs. 59.5 ± 11.4 years) and had higher high-density lipoprotein cholesterol levels (49.0 ± 12.8 vs. 43.6 ± 11.6 mg/dl, P  < 0.01). The prevalence of diabetes did not differ significantly ( P  = 0.40), and smoking was more common in men than in postmenopausal women ( P  ≤ 0.01). At enrollment, b-CAD and revascularization were more common in men than in postmenopausal women (50.3% vs. 41.0% and 14.4% vs. 9.7%, respectively; both P  < 0.01). However, multivariate analyses revealed that revascularization [odds ratio (OR): 0.72; 95% confidence interval (CI): 0.49-1.08] was not significantly related to sex and a similar result was found in age propensity-matched population (OR: 0.80; 95% CI: 0.52-1.24). During the follow-up period, the secondary composite cardiovascular outcomes were lower in postmenopausal women than in men (OR: 0.55; 95% CI: 0.31-0.98), also consistent with the result using the age propensity-mated population (OR: 0.33; 95% CI: 0.13-0.85).

CONCLUSION

Postmenopausal women experienced coronary revascularization comparable to those in men at enrollment, despite the average age of postmenopausal women was 7 years older than that of men.Postmenopausal women exhibit better clinical outcomes than those of men if optimal treatment is provided.

Differences in Risk Factors for Coronary Atherosclerosis According to Sex

Interest in sex differences related to coronary artery disease (CAD) has steadily increased, and the risk factors for CAD show distinct sex differences. For women, cardiovascular risk increases significantly after menopause due to a decrease in estrogen levels. In older individuals, increased arterial stiffness results in a higher pulse pressure, leading to a more common occurrence of isolated systolic hypertension; these changes are more noticeable in women. While the incidence of diabetes is similar in both sexes, women with diabetes face a 50% higher relative risk of fatal coronary heart disease compared to men. Smoking significantly increases the risk of ischemic heart disease in women, particularly those who are younger. The decrease in estrogen in women leads to a redistribution of fat, resulting in increased abdominal obesity and, consequently, an elevated cardiovascular risk. Pregnancy and reproductive factors also have a significant impact on CAD risks in women. Additionally, disparities exist in medical practice. Women are less likely to be prescribed cardioprotective drugs, referred for interventional or surgical treatments, or included in clinical research than men. By increasing awareness of these sex differences and addressing the disparities, we can progress toward more personalized treatment strategies, ultimately improving patient outcomes.

Sex Differences in Coronary Artery Disease: Insights From the KoRean wOmen'S chest pain rEgistry (KoROSE)

Interest in sex differences in coronary artery disease (CAD) has been steadily increasing. Concurrently, most of the data on these differences have primarily been Western-oriented. The KoRean wOmen'S chest pain rEgistry (KoROSE), started in 2011, has since published numerous research findings. This review aims to summarize the reported differences between men and women in CAD, integrating data from KoROSE. Cardiovascular risk in postmenopausal women escalates dramatically due to the decrease in estrogen levels, which normally offer cardiovascular protective effects. Lower estrogen levels can lead to abdominal obesity, insulin resistance, increased blood pressure, and endothelial dysfunction in older women. Upon analyzing patients with CAD, women are typically older and exhibit more cardiovascular risk factors than men. Diagnosing CAD in women tends to be delayed due to their symptoms being more atypical than men's. While in-hospital outcome was similar between sexes, bleeding complications after percutaneous coronary intervention occur more frequently in women. The differences in long-term prognosis for CAD patients between men and women are still a subject of ongoing debate. Pregnancy and reproductive factors also play a significant role as risk factors for cardiovascular disease in women. A notable sex disparity exists, with women found to use fewer cardiovascular protective drugs and undergo fewer interventional or surgical procedures than men. Additionally, women participate less frequently than men in clinical research. Through concerted efforts to increase awareness of sex differences and mitigate sex disparity, personalized treatment can be provided. This approach can ultimately improve patient prognosis.

Associations of depression and anxiety with cardiovascular risk among people living with HIV/AIDS in Korea

OBJECTIVES

As HIV/AIDS is becoming a chronic disease, the risk of developing cardiovascular disease (CVD) among people living with HIV/AIDS is rising. Anxiety and depression, which are common among people living with HIV/AIDS, have been linked with CVD. This study investigated the risk of CVD in people living with HIV/AIDS and explored the effects of depression and anxiety on CVD risk.

METHODS

Data were collected for 457 people enrolled in the Korea Cohort HIV/AIDS study after 2010. Framingham risk scores were calculated to quantify the 10-year risk of developing CVD. Depression and anxiety variables were re-coded as a single combined variable. Multivariable logistic regression analysis was performed, adjusting for age, body mass index, low-density lipoprotein (LDL) cholesterol, triglycerides (TG), duration of human immunodeficiency virus (HIV) positivity after entry into the cohort, and depression/anxiety.

RESULTS

Participants with both depression and anxiety were 2.28 times more likely than those with neither depression nor anxiety to have moderate/high-risk CVD risk. The 10-year risk of developing CVD was affected by LDL cholesterol, TG, age, and duration of HIV infection. LDL cholesterol and TG levels change according to the duration of HIV infection, and metabolic disorders affect the risk of CVD. Thus, a longer duration of HIV infection is associated with a higher risk of developing CVD.

CONCLUSIONS

Screenings for depression and anxiety need to be provided regularly to assess the severity of those symptoms. To help decrease their risk of developing CVD, people living with HIV/AIDS should be offered behavioral modification interventions aimed at developing healthy lifestyle habits.

Sex Difference in the Association Between Metabolic Syndrome and Obstructive Coronary Artery Disease: Analysis of Data from the KoRean wOmen'S chest pain rEgistry (KoROSE)

Background: The sex-related impact of metabolic syndrome (MetS) on obstructive coronary artery disease (OCAD) has not been well evaluated. Methods: A total of 1156 patients (62 years and 58% women) with chest pain undergoing invasive coronary angiography (CAG) were recruited from the database of the nation-wide chest pain registry. MetS was defined according to the criteria of the International Diabetes Federation. OCAD was defined as ≥50% stenosis of the left main coronary artery and/or ≥70% stenosis of any other coronary arteries. Results: Women were older than men (65 vs. 59 years, p < 0.001). OCAD (32.0% vs. 30.9%) and MetS (27.8% vs. 27.9%) prevalence rates were similar in both sexes (p > 0.05). The presence of MetS was associated with higher prevalence of OCAD in women (24.5% vs. 47.3%, p < 0.001), but not in men (31.0% vs. 34.3%, p = 0.487). The linear association between the number of components meeting MetS criteria and OCAD prevalence was significant in both sexes (p < 0.001 for each), but it was stronger in women than in men (Chi-square value: 81.9 vs. 14.8, p < 0.001). In a multivariable model, the presence of MetS was independently associated with OCAD in women even after controlling for potential confounders (odds ratio, 1.92; 95% confidence interval, 1.31-2.81; p = 0.001). Conclusions: In patients with chest pain undergoing invasive CAG, the association between the number of components meeting MetS criteria and OCAD prevalence was stronger in women than in men.

The relationship between epicardial adipose tissue and coronary artery stenosis by sex and menopausal status in patients with suspected angina

Background

Evidence suggests that epicardial adipose tissue (EAT) is closely related to coronary artery stenosis (CAS). However, sexual dimorphism may be present in adipose tissue, and its influence on CAS between men and women is controversial. We assessed the relationship between EAT and CAS by sex and menopausal status in patients with suspected angina.

Methods

Six hundred twenty-eight consecutive patients (men/women n = 257/371; mean age = 59.9 ± 10.2 years) who had chest pain for angina and underwent coronary angiography were included. CAS was defined as > 50% luminal narrowing of at least one epicardial coronary artery. EAT thickness was measured by transthoracic echocardiography.

Results

Of the 628 patients, 52.1% (n = 134) of men and 35.3% (n = 131) of women had CAS. The mean EAT thickness was not different between men and women and was larger in patients with CAS (8.04 ± 2.39 vs 6.58 ± 1.88 mm, P < 0.001). EAT thickness was independently associated with CAS in both sexes (P < 0.001). The odds ratio (OR) of EAT for the presence of CAS was higher in men (OR = 1.43, 95% confidence interval [CI] 1.21–1.69) than in women (OR = 1.24, 95% CI 1.10–1.40). EAT thickness was larger in postmenopausal women than in premenopausal women (7.59 ± 2.25 vs 5.80 ± 1.57 mm, P < 0.001) and was independently related with CAS (OR = 1.24, 95% CI 1.09–1.41). This was not the case in premenopausal women.

Conclusion

In patients with suspected angina, an increase in EAT thickness was independently related to the presence of CAS in both men and women, with it being stronger in men. According to menopausal status in women, EAT thickness is significantly associated with CAS only in postmenopausal women.

Relationships between blood pressure measurements and target organ damage: Data from the Korea women's chest pain registry

This study was performed to investigate the association between four BP measurements (systolic blood pressure [SBP], diastolic blood pressure [DBP], mean arterial pressure [MAP], and pulse pressure [PP]) and four TOD parameters (left ventricular mass index [LVMI], E/e', estimated glomerular filtration rate [eGFR], and obstructive coronary artery disease [CAD]). Data were obtained from a nation-wide registry, composed of 652 patients (471 women, 58.4 ± 10.5 years) with suspected CAD who underwent elective invasive coronary angiography (CAG). A total of 217 patients (33.2%) had obstructive CAD (≥50%). In multivariable analyses, E/e' was associated with SBP, MAP and PP, and CAD was associated with SBP and PP (P < 0.05 for each). All four BP measurements were not associated with LVMI and eGFR (P > 0.05 for each). In patients undergoing elective invasive CAG, SBP, and PP had stronger relationships with E/e' and CAD than DBP and MAP.

Biological activities of (-)-epicatechin and (-)-epicatechin-containing foods: Focus on cardiovascular and neuropsychological health

Recent studies have suggested that certain (-)-epicatechin-containing foods have a blood pressure-lowering capacity. The mechanisms underlying (-)-epicatechin action may help prevent oxidative damage and endothelial dysfunction, which have both been associated with hypertension and certain brain disorders. Moreover, (-)-epicatechin has been shown to modify metabolic profile, blood's rheological properties, and to cross the blood-brain barrier. Thus, (-)-epicatechin causes multiple actions that may provide unique synergy beneficial for cardiovascular and neuropsychological health. This review summarises the current knowledge on the biological actions of (-)-epicatechin, related to cardiovascular and brain functions, which may play a remarkable role in human health and longevity.

Impact of Mindfulness Based Stress Reduction Therapy on Myocardial Function and Endothelial Dysfunction in Female Patients with Microvascular Angina

Background

Mindfulness-based stress reduction (MBSR) is a structured group program that employs mindfulness meditation to alleviate suffering associated with physical, psychosomatic, and psychiatric disorders. In this study, we investigate the impact of MBSR on left ventricular (LV) and endothelial function in female patients with microvascular angina.

Methods

A total of 34 female patients (mean age 52.2 ± 13.8 years) diagnosed with microvascular angina underwent a MBSR program with anti-anginal medication for 8 weeks. The global longitudinal strain (GLS) of the LV was used as a parameter to assess myocardial function and reactive brachial flow-mediated dilatation (FMD) was used to assess endothelial function. Symptoms were analyzed by the Symptom Checklist 90 Revised to determine emotional stress. Changes in GLS and FMD between baseline and post-MBSR were analyzed.

Results

After 8 weeks of programmed MBSR treatment, stress parameters were significantly decreased. In addition, GLS (−19.5 ± 2.1% vs. −16.6 ± 2.5%, p < 0.001) and reactive FMD significantly improved (8.9 ± 3.0% vs. 6.9 ± 2.6%, p = 0.005) after MBSR compared to baseline. The changes in GLS correlated to changes in FMD (r = 0.120, p = 0.340) and with the changes in most stress parameters.

Conclusion

MBSR has beneficial impacts on myocardial and endothelial function in female patients with microvascular angina.

Women, Stress and Heart Health: Mindfulness-Based Stress Reduction and Cardiovascular Disease

Psychological stress including depression and anxiety are independent risk factors for cardiovascular disease morbidity and mortality, especially in women. Emotional regulation plays a mediating role in the development of depression and physical illness, and can alter resting physiologic responses associated with the stress response. Mindfulness-based stress reduction (MBSR) is a structured group program that employs mindfulness meditation to alleviate suffering associated with physical, psychosomatic, and psychiatric disorders. MBSR was originally developed for the management of chronic pain, which is now used widely to reduce psychological morbidity associated with chronic illnesses and to treat emotional and behavioral disorders. In cardiovascular disease, MBSR may be helpful for controlling several risk factors for coronary heart disease such as hypertension, type 2 diabetes mellitus, dyslipidemia, oxidative and psychosocial stress, obesity, and smoking, and improvements in submaximal exercise responses and heart rate variability. Although the most effective mode of stress reduction therapy is yet to be established, increasing recognition is being given to MBSR therapy.

Sex Difference in the Association Between Brachial Pulse Pressure and Coronary Artery Disease: The Korean Women's Chest Pain Registry (KoROSE)

This study was performed to investigate the association between brachial pulse pressure (PP) and the presence/extent of obstructive coronary artery disease (CAD) in men and women. Study data were obtained from a nation-wide registry composed of 632 patients (173 men and 459 women, 58.1±10.5 years) with suspected CAD who underwent invasive coronary angiography. PP was higher in patients with obstructive CAD (≥50% stenosis) than those without CAD in both sexes (P=.032 in men; P<.001 in women). However, PP increased proportionally with the increasing number of obstructed coronary arteries in women (P<.001) but not in men (P=.070). Multiple logistic-regression analyses demonstrated that higher PP (≥50.5 mm Hg) was an independent factor for determining obstructive CAD even after controlling for potential confounders in women (odds ratio, 2.83; 95% confidence interval, 1.40-5.73; P=.004). These results were consistent in 173 selected women matched with 173 men based on age and CAD severity. In conclusion, the association between brachial PP and obstructive CAD was more pronounced in women than in men. Brachial PP can be a simple and useful indicator of CAD especially in women.
