Patient Notification About Breast Arterial Calcification on Mammography: Empowering Women With Information About Cardiovascular Risk.

OBJECTIVE: To assess the impact of informing women about the presence of breast arterial calcification (BAC) on mammography by determining whether those notified about the presence of BAC would seek cardiovascular evaluation. METHODS: This IRB-approved prospective study included 494 patients who underwent screening mammography between June 8, 2021, and April 22, 2022. Mammograms were reviewed by a radiologist, and patients were notified via e-mail about the presence or absence of BAC. Patients with BAC were advised to discuss the results with their physicians and were surveyed 3 months later. Frequencies and proportions were calculated for study participation, presence of BAC, survey participation, health actions, and perceptions. Confidence intervals were calculated for proportions of health actions and perceptions. RESULTS: Of 494 study participants, 68/494 (13.8%; 95% CI: 10.9%-17.1%) had BAC detected on mammography and 42/68 (61.8%; 95% CI: 61.1%-62.1%) with BAC completed the follow-up survey at 3 months. Of these 42 survey respondents, 24/42 (57.1%; 95% CI: 41.1%-72.3%) reported discussing results with their primary care physician (PCP) or a cardiologist. In addition, 34/42 (81.0%; 95% CI: 65.9%-91.4%) reported finding it helpful to receive information about BAC and 32/42 (76.2%; 95% CI: 60.6%-88.0%) believed all women should be informed about BAC after mammography. CONCLUSION: After notification about the presence of BAC on screening mammography, the majority (57.1%) of survey respondents reported discussing the results with a PCP or cardiologist. These results suggest that providing mammography patients with information about BAC may promote preventive cardiovascular health.

Racial and Ethnic Differences in Awareness and Prevalence of Unidentified Cardiovascular Risk Factors Among Health System Employees.

PURPOSE: To evaluate awareness about cardiovascular (CVD) risk among a racially and ethnically diverse cohort of health system employees. DESIGN: Cross-sectional study. SETTING: Voluntary survey of health system employees during an annual CVD awareness and screening event. SUBJECTS: 759 health system employees. MEASURES: We performed initial CVD screening measurements (blood pressure, body mass index) and collected patient-reported answers to questions about their own CVD risk factors (hypertension, high cholesterol, diabetes, overweight, smoking, physical inactivity and family history of CVD) and whether or not they believed that CVD is preventable. Subjects were offered in-depth follow-up CVD screening (lipid panel, hs-CRP, hemoglobin A1c), if interested. ANALYSIS: Continuous measures were compared across sex and racial/ethnic subsets using a t test and analysis of variance technique. Univariable and multivariable logistic regression models were used to estimate the employee's willingness to undergo further comprehensive screening. RESULTS: African American, Hispanic, and Asian employees were younger than white employees (P < .0001). More than one-quarter of African Americans reported a history of hypertension, a higher rate than for other subgroups (P = .001). The rate of self-reported diabetes was highest in African American and Asian employees (P = .001). African Americans had a 54% reduced odds of electing to pursue follow-up CVD screening (odds ratio: .46, 95% confidence interval = .24-.91, P = .025). CONCLUSION: Presence of CVD risk factors and knowledge of their importance differ among racial and ethnic groups of health system employees in our cohort as does interest in pursuing follow-up screening once risk factors are identified. Development of evidence-based customization strategies by racial and ethnic group may improve understanding of and interest in CVD risk factors and advance prevention. The data from this study will inform future research and strategies for employee health promotion.

Sex-Specific Disparities in Risk Factors for Coronary Heart Disease.

In the past two decades, focused research on women at risk for cardiovascular disease (CVD) has helped to clarify our understanding of some of the sex-specific factors that are important in the prevention and early detection of coronary atherosclerosis with a resultant 30 % decrease in the number of women dying from CVD. In spite of these advances, CVD, specifically, ischemic heart disease due to coronary atherosclerosis is the leading cause of cardiovascular death of women in the USA. The 2010 landmark Institute of Medicine (IOM) report, "Women's Health Research--Progress, Pitfalls and Promise," highlighted the fact that although major progress had been made in reducing cardiovascular mortality in women, there were disparities in disease burden among subgroups of women, particularly those women who are socially disadvantaged because of race, ethnicity, income level, and educational attainment [1]. The IOM recommended targeted research on these subpopulations of women with the highest risk and burden of disease. Causes of disparities are multifactorial and are related to differences in risk factor prevalence, access to care, use of evidence-based guidelines, and social and environmental factors. In this article, we review a few of the contributing factors to the disparities in ischemic heart disease in women with a focus on the subgroups of women of Black, Latino, and South Asian descent who are at high risk for morbidity and mortality from CVD.

Imaging Tests, Provocative Tests, Including Exercise Testing in Women with Suspected Coronary Artery Disease.

Evolving knowledge regarding sex differences in coronary heart disease has demonstrated that the prevalence, symptomatology, and pathophysiology of coronary atherosclerosis vary between genders. Women experience higher mortality rates and more adverse outcomes after acute myocardial infarction than men, despite a lower prevalence of obstructive coronary artery disease. Based on recent insights into the complex pathophysiology of coronary heart disease which includes a spectrum of obstructive coronary artery disease and dysfunction of the coronary microvasculature and endothelium, the term ischemic heart disease is a more accurate term for discussion of coronary atherosclerosis specific to women. In women, with clinical features and risk factors for ischemic heart disease, the detection and evaluation of ischemic heart disease is challenging due to the diverse pathogenic mechanisms of ischemic heart diseases in women. In this article, we discuss noninvasive imaging tests, provocative tests, including exercise testing in women with suspected ischemic heart disease.

Noninvasive diagnostic techniques for coronary disease in women.

Significant advances in medical treatment, medical technology, and the focus on sex-specific research have contributed to a reduction in cardiovascular mortality in women. Despite these advances, coronary artery disease (CAD) is the leading cause of cardiovascular death of women in the Western world. In the past 2 decades, the focused research on women at risk for CAD has helped to clarify our understanding of some of the sex-specific factors that are important in the detection of CAD. In women, the detection and evaluation of physiologically significant CAD can be challenging. Many of the traditional tests that are designed to detect focal areas of coronary artery stenosis are less sensitive and specific in female patients, who have a greater burden of symptoms, higher atherosclerotic burden, and lower prevalence of obstructive coronary disease. In this article, we review the available evidence on the role of contemporary noninvasive diagnostic techniques in the evaluation of women with symptoms of CAD. The authors have no funding, financial relationships, or conflicts of interest to disclose.

Value of electrocardiographically gated single-photon emission computed tomographic myocardial perfusion scintigraphy in a cohort of symptomatic postmenopausal women.

The aim of this study is to prospectively evaluate the clinical value of electrocardiographically gated single-photon emission computed tomographic myocardial perfusion scintigraphy (MPS) imaging in a cohort of postmenopausal women with symptoms suggestive of ischemic heart disease. Forty-six postmenopausal women with no history of coronary artery disease (CAD), but with typical or atypical angina and >or=1 risk factor for CAD, were enrolled and underwent both coronary angiography and technetium-99m sestamibi MPS with exercise (n = 36) or pharmacologic stress (n = 10). All women were followed up for 5.0 +/- 3 years for the occurrence of hospitalization for acute coronary syndrome, myocardial infarction, and/or new-onset or worsening angina. CAD prevalence (>or=50% diameter stenosis) was 62% (26 of 42 patients). Fifteen patients (36%) had 1-vessel disease, 7 (17%) had 2-vessel disease, and 4 (10%) had 3-vessel disease. Diagnostic sensitivity and specificity of the exercise electrocardiogram were 67% and 69%, respectively. By comparison, sensitivity of MPS was 88% and specificity was 87.5% (p <0.0001). Cox survival analysis showed 3- and 5-year cumulative event-free survival rates of 97% and 94% for patients with normal MPS results compared with 60% and 48% for those with abnormal MPS findings (p <0.001). In conclusion, results of this study indicate high diagnostic and prognostic accuracy for MPS in symptomatic postmenopausal women.

Successful preterm delivery in a patient with severe mitral stenosis.

We present the case of a 36-year-old woman who was diagnosed with severe mitral stenosis in the 30th week of a pregnancy that was complicated by complete placenta previa and placenta percreta. With medical management, she successfully carried the pregnancy to fetal viability and was delivered by cesarean section before undergoing percutaneous balloon mitral valvuloplasty.

Large left ventricular pseudoaneurysm presenting 25 years after penetrating chest trauma.

Penetrating chest wounds leading to damage of thoracic structures are common. A rare sequelae of chest trauma is a contained rupture of the left ventricle of the heart leading to the development of a pseudoaneurysm. This complication needs prompt recognition and repair because of the high likelihood of rupture and death. We report the case of a 47-year-old man who underwent repair of a stab wound to the heart 25 years ago and subsequently developed a large left ventricular pseudoaneurysm and presented with angina.

Thrombosed right coronary artery aneurysm presenting as a myocardial mass.

A coronary artery aneurysm is defined as coronary dilatation that exceeds the diameter of normal adjacent artery segments, or is 1.5 times the diameter of the largest coronary artery. Coronary artery aneurysms are rare with an incidence of between 1.5% to 5%. The aneurysm is caused by destruction of the vessel media, thinning of the arterial wall, increased wall stress, and progressive dilatation of a segment of the coronary artery. The most common cause is atherosclerotic coronary artery disease. These aneurysms occasionally rupture but more commonly develop thrombus and hematoma leading to the appearance of the presence of an intramyocardial mass. We present the case of a 60-year-old man with hypertension who presented with a mass that was identified initially by transthoracic echocardiography in the setting of an inferior wall myocardial infarction, which was later recognized to be a thrombosed right coronary artery aneurysm.

Hemodynamic instability after receiving intravenous Perflutren for contrast echocardiography in an elderly female.

Myocardial contrast echocardiography (MCE) has been used with increasing frequency and is considered a safe way to improve left ventricular border opacification. Studies have consistently documented that MCE can improve the ability to assess both global and regional left ventricular function by echocardiography. We report the case of an 83-year-old female who developed immediate and sustained hemodynamic instability after the injection of Perflutren for a contrast echocardiogram. We reviewed the literature and found no such previous reactions with Perflutren. Based on the temporal sequence of hypotension following Perflutren injection along with other clinical data, we concluded that our patient's hemodynamic instability was most likely secondary to an anaphylactic reaction.

Survival to the age of 52 years in a man with unrepaired tetralogy of Fallot.

Tetralogy of Fallot is the most common cyanotic congenital heart defect during infancy. It is composed of a ventricular septal defect, an overriding aorta, obstruction of right ventricular outflow, and right ventricular hypertrophy. Most patients experience cyanosis at birth and die in childhood without surgical intervention. The rate of survival at 40 years without surgical correction is only 3%. We present the case of a man with tetralogy of Fallot who survived until the age of 52 years without surgical intervention.
