Background: Most studies have compared post-treatment electrocardiogram (ECG) abnormalities in cancer patients to the general population. To assess baseline cardiovascular (CV) risk, we compared pre-treatment ECG abnormalities in cancer patients with a non-cancer surgical population.

Methods: We conducted a combined prospective (n = 30) and retrospective (n = 229) cohort study of patients aged 18 - 80 years with diagnosis of hematologic or solid malignancy, compared with 267 pre-surgical, non-cancer, age- and sex-matched controls.

In the cardio-oncology population, drug interactions are of particular importance given the complex pharmacological profile, narrow therapeutic index, and inherent risk of therapies used to manage cardiovascular disease and cancer. Drug interactions may be beneficial or detrimental to the desired therapeutic effect. Clinicians in both cardiology and oncology should be cognizant of these potential drug-drug interactions that may reduce the efficacy or safety of either cardiovascular or cancer therapies.

Cardiovascular disease is one of the leading causes of morbidity and mortality in persons with cancer. The elevated risk is thought to derive from the combination of cardiovascular risk factors and direct cardiotoxicity from cancer therapies. Exercise may be a potential strategy to counteract these toxicities and maintain cardiovascular reserve.

Cardiovascular disease and cancer are the leading causes of death in the United States, and hormone-dependent cancers (breast and prostate cancer) are the most common noncutaneous malignancies in women and men, respectively. The hormonal (endocrine-related) therapies that serve as a backbone for treatment of both cancers improve survival but also increase cardiovascular morbidity and mortality among survivors. This consensus statement describes the risks associated with specific hormonal therapies used to treat breast and prostate cancer and provides an evidence-based approach to prevent and detect adverse cardiovascular outcomes.

Background: Multiple studies have investigated the role of statins in prostate cancer (CaP), the leading cause of cancer related death in men. Retrospective cohort studies investigating the correlation between statin use and biochemical recurrence free (BCRF) survival in men with CaP have been inconclusive.

Objectives: In the largest reported surgical cohort to date, we investigated the effect of statin therapy on BCRF and overall survival in patients with CaP who have undergone radical prostatectomy (RP).

Objectives: The purpose of this study was to investigate whether pre-diagnosis exercise reduces the risk of subsequent cardiovascular events (CVEs) in women with primary breast cancer.

Background: Cardiovascular disease (CVD) is the leading nonmalignant cause of death in patients with cancer, and it is the leading cause of death in women with primary breast cancer who are older than 65 years of age.

Methods: Using a prospective design, 4,015 patients with confirmed diagnosis of primary breast cancer enrolled in the Women's Health Initiative (WHI) completed a self-report questionnaire assessing leisure-time physical activity (i.

Objective: Given the increasing evidence that obesity increases the risk of developing and dying from malignancy, the American Society of Clinical Oncology (ASCO) launched an Obesity Initiative in 2013 that was designed to increase awareness among oncology providers and the general public of the relationship between obesity and cancer and to promote research in this area. Recognizing that the type of societal change required to impact the obesity epidemic will require a broad-based effort, ASCO hosted the "Summit on Addressing Obesity through Multidisciplinary Collaboration" in 2016.

Methods: This meeting was held to review current challenges in addressing obesity within the respective health care provider communities and to identify priorities that would most benefit from a collective and cross-disciplinary approach.

Certain cancer therapies, including radiation therapy and some types of chemotherapies, are associated with increased risk of cardiovascular disease (CVD) and events. Some of these effects such as those presented by anthracyclines, radiation therapy, cisplatin, as well as those presented by hormone therapy for breast cancer-usually taken for many years for some breast and prostate cancers-are long-lasting and associated with cardiovascular events risk more than 20 years after cancer treatment. Cardiovascular testing, diagnostic assessment of suspected cardiovascular symptomatology, as well as laboratory tests for CVD risk factors are imperative.

Background: The presence and burden of coronary artery calcium (CAC) is a strong predictor of cardiovascular events. In an effort to gain insight into the utility of CAC for coronary artery disease (CAD) screening in cancer patients with heart disease, we sought to determine the presence and burden of CAC detected on routine chest CT in patients referred to a cardio-oncology clinic, comparing them to a conventional cardiology clinic with the general population as controls.

Methods: Patients from the cardio-oncology clinic, general cardiology clinic, and the general clinic population at Rush University Medical Center who had a chest CT as part of their previous treatment were identified.

Many existing and emerging cancer therapies have a significant effect on the cardiovascular health of patients with cancer and cancer survivors. This paper examines current aspects of interdisciplinary cardio-oncology clinical care delivery and education in the United States and outlines how these data provide a platform for future development of the field. We present the results of the nationwide survey on cardio-oncology services, practices, and opinions, conducted among chiefs of cardiology and program directors, which demonstrate ranges of clinical activities and identify significant interest for increased educational opportunities and expert training of cardiovascular physicians in this field.

Background: Left ventricular hypertrophy (LVH) is a major independent predictor of cardiovascular disease (CVD) survival and is more prevalent in blacks than whites. In a large biracial population, we evaluated the ability of electrocardiography (ECG)-determined LVH (ECG-LVH) to reclassify CVD/coronary heart disease (CHD) events beyond traditional risk factors in blacks and whites.

Methods: The analysis included 14,489 participants (mean age 54 ± 5.

Cardiovascular disease (CVD) remains the leading cause of mortality both in the United States and worldwide. Traditional risk factors are essential to CVD risk prediction and explain a significant portion of the between-population and between-individual variance in CVD. Nonetheless, due to the large size of the group, a substantial portion of cardiovascular events occur in individuals predicted to be at low risk based on traditional risk factor models such as the Framingham risk score.

Objective: To examine long-term associations between change in alcohol-consumption status and cessation of alcohol use, and fibrinogen levels in a large, young, biracial cohort.

Design: Analysis of covariance models were used to analyse participants within the Coronary Artery Risk Development in Young Adults Study (CARDIA) cohort who had fibrinogen and alcohol use data at year 7 (1992-1993; ages 25-37) and year 20 examinations.

Setting: 4 urban US cities.

Objective: Cross-sectional and prospective studies have linked cardiovascular events and traditional risk factors (TRFs) with higher plasma fibrinogen levels. In a young cohort, we sought to determine longitudinal associations between changes in/development of TRFs and fibrinogen levels over 13 years.

Methods: We included 2525 adults from the CARDIA study, aged 25-37 with fibrinogen and TRFs measured at year 7 (study baseline; 1992-1993); and year 20 (follow-up).

Objectives: The purpose of this study was to assess the prevalence and distribution of coronary artery calcium (CAC) across Framingham Risk Score (FRS) strata and therefore determine FRS levels at which asymptomatic, young to early middle-age individuals could potentially benefit from CAC screening.

Background: High CAC burden is associated with increased risk of coronary events beyond the FRS. Expert panel recommendations for CAC screening are based on data obtained in middle-age and older individuals.

Objectives: This study sought to determine whether novel markers not involving ionizing radiation could predict coronary artery calcium (CAC) progression in a low-risk population.

Background: Increase in CAC scores over time (CAC progression) improves prediction of coronary heart disease (CHD) events. Due to radiation exposure, CAC measurement represents an undesirable method for repeated risk assessment, particularly in individuals with low predicted risk (Framingham Risk Score [FRS] <10%).

Objectives: By examining the distribution of coronary artery calcium (CAC) levels across Framingham risk score (FRS) strata in a large, multiethnic, community-based sample of men and women, we sought to determine if lower-risk persons could benefit from CAC screening.

Background: The 10-year FRS and CAC levels are predictors of coronary heart disease. A CAC level of 300 or more is associated with the highest risk for coronary heart disease even in low-risk persons (FRS, <10%); however, expert groups have suggested CAC screening only in intermediate-risk groups (FRS, 10% to 20%).

Even among asymptomatic persons at low risk (<10%) according to the Framingham risk score, high coronary artery calcium (CAC) scores signify a greater predicted risk of coronary heart disease events. We sought to determine the noninvasive factors (without radiation exposure) significantly associated with CAC in low-risk, asymptomatic persons. In a cross-sectional analysis, we studied 3,046 participants from the Multi-Ethnic Study of Atherosclerosis at a low 10-year predicted risk (Framingham risk score <10%) of coronary heart disease events.
