Background: Hypertension is an important contributor to cardiovascular disease (CVD) in breast cancer (BC) survivors; however, research on blood pressure (BP) and CVD outcomes in BC survivors is limited.

Objectives: The purpose of this study was to better characterize the association between BP and CVD in a large, longitudinal cohort of BC patients.

Methods: Women with invasive BC diagnosed from 2005 to 2013 at Kaiser Permanente Northern California were matched 1:5 to women without BC.

As cancer therapies increase in effectiveness and patients' life expectancies improve, balancing oncologic efficacy while reducing acute and long-term cardiovascular toxicities has become of paramount importance. To address this pressing need, the Cardiology Oncology Innovation Network (COIN) was formed to bring together domain experts with the overarching goal of collaboratively investigating, applying, and educating widely on various forms of innovation to improve the quality of life and cardiovascular healthcare of patients undergoing and surviving cancer therapies. The COIN mission pillars of innovation, collaboration, and education have been implemented with cross-collaboration among academic institutions, private and public establishments, and industry and technology companies.

The prevalence of concurrent cancer and severe aortic stenosis (AS) is increasing due to an ageing population. In addition to shared traditional risk factors for AS and cancer, patients with cancer may be at increased risk for AS due to off-target effects of cancer-related therapy, such as mediastinal radiation therapy (XRT), as well as shared non-traditional pathophysiological mechanisms. Compared with surgical aortic valve replacement, major adverse events are generally lower in patients with cancer undergoing transcatheter aortic valve intervention (TAVI), especially in those with history of mediastinal XRT.

Background Despite the belief that heart failure therapies are not effective in transthyretin cardiac amyloidosis, data are limited. We tested the association of neurohormonal blockade use with survival. Methods and Results A total of 309 consecutive patients with transthyretin cardiac amyloidosis were identified.

Cancer and coronary artery disease (CAD) overlap in traditional risk factors as well as molecular mechanisms underpinning the development of these two disease states. Patients with cancer are at increased risk of developing CAD, representing a high-risk population that are increasingly undergoing coronary revascularisation. Over 1 in 10 patients with CAD that require revascularisation with either percutaneous coronary intervention or coronary artery bypass grafting have either a history of cancer or active cancer.

Increasing evidence suggests a multifaceted relationship exists between cancer and cardiovascular disease (CVD). Here, we introduce a 5-tier classification system to categorize cardio-oncology syndromes (COS) that represent the aspects of the relationship between cancer and CVD. COS Type I is characterized by mechanisms whereby the abrupt onset or progression of cancer can lead to cardiovascular dysfunction.

Aims: There is conflicting evidence whether heart failure (HF) is a risk factor for incident cancer. Despite population-based cohorts demonstrating this association, an analysis of the Physician's Health Study found no association in a cohort of mostly healthy males. We investigated the association of HF with incident cancer among a large cohort of post-menopausal women.

Background: With increasing diagnoses and available treatment options for transthyretin amyloidosis cardiomyopathy (ATTR-CM), risk stratification of ATTR-CM patients is imperative.

Objectives: We hypothesized that diuretic dose and New York Heart Association (NYHA) functional class are independent predictors of mortality in ATTR-CM and would be incrementally additive to existent risk scores.

Methods: Consecutive ATTR-CM patients referred to a single center were identified.

Background: A Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-CI) was previously developed showing that multiple comorbidities including moderate or greater valvular heart disease to be predictors of non-relapse mortality after allogeneic HCT. However, detailed description of the impact of valve disease on outcomes is lacking.

Methods: Among a large cohort of patients given allogeneic HCT between 2000 and 2017, we identified 21 patients with moderate or severe valvular disease.

Purpose Of Review: Cancer and cardiovascular disease are the leading causes of mortality in the USA. In this review, we highlight these shared disease pathways and provide a framework for a systems-based approach to reduce overall risk burden.

Recent Findings: From traditional risk factors such as age and tobacco use to more recently recognized entities including clonal hematopoiesis, we are gaining insights into shared mechanisms.
