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.

Cardiotoxicity screening of long-term, breast cancer survivors-The CAROLE (Cardiac-Related Oncologic Late Effects) Study.

BACKGROUND: Long-term breast cancer survivors are at risk for cardiotoxicity after treatment, but there is insufficient evidence to provide long-term (~10 years) cardiovascular disease (CVD) screening recommendations. We sought to evaluate a tri-modality CVD screening approach. METHODS: This single-arm, feasibility study enrolled 201 breast cancer patients treated ≥6 years prior without CVD at diagnosis. Patients were sub-grouped: cardiotoxic (left-sided) radiation (RT), cardiotoxic (anthracycline-based) chemotherapy, both cardiotoxic chemotherapy and RT, and neither cardiotoxic treatment. Patients underwent electrocardiogram (EKG), transthoracic echocardiogram with strain (TTE with GLS), and coronary artery calcium computed tomography (CAC CT). The primary endpoint was preclinical or clinical CVD. RESULTS: Median age was 50 (29-65) at diagnosis and 63 (37-77) at imaging; median interval was 11.5 years (6.7-14.5). Among sub-groups, 44% had no cardiotoxic treatment, 31.5% had cardiotoxic RT, 16% had cardiotoxic chemotherapy, and 8.5% had both. Overall, 77.6% showed preclinical and/or clinical CVD and 51.5% showed clinical CVD. Per modality, rates of any CVD and clinical CVD were, respectively: 27.1%/10.0% on EKG, 50.0%/25.3% on TTE with GLS, and 50.8%/45.8% on CAC CT. No statistical difference was seen among the treatment subgroups (NS, χ2 test, p = 0.58/p = 0.15). CONCLUSION: This study identified a high incidence of CVD in heterogenous long-term breast cancer survivors, most >10 years post-treatment. Over half had clinical CVD findings warranting follow-up and/or intervention. Each imaging test independently contributed to the detection rate. This provides early evidence that long-term cardiac screening may be of value to a wider group of breast cancer survivors than previously recognized.

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.

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.

Pericardial cyst: case reports and a literature review.

Pericardial cysts are rare mediastinal abnormalities, which are usually congenital but may also be acquired after cardiothoracic surgery. Cysts frequently occur in the right cardiophrenic angle and their diagnosis is usually suspected after an abnormal chest X ray is obtained. The presence of a pericardial cyst in this typical location or, less frequently, in an unusual location, poses a diagnostic challenge in distinguishing it from other intracardiac or mediastinal abnormalities. Two-dimensional echocardiography and transesophageal echocardiography are extremely valuable in diagnosing the presence of a pericardial cyst. Although most pericardial cysts are asymptomatic, patients may present with chest pain and dyspnea. In addition, life-threatening complications such as pericardial tamponade have been reported in association with pericardial cysts. The following cases illustrate the usefulness of two-dimensional echocardiography in making an accurate diagnosis of a pericardial cyst, as well as in follow-up of these patients for the development of possible complications.
