Platelets possess a dynamic functional repertoire that mediates hemostatic and inflammatory responses. Many of these functions are altered in older adults, promoting a pro-thrombotic and pro-inflammatory milieu and contributing to an increased risk of adverse clinical events. This review summarizes, drawing primarily from human studies, key aspects of aging-related changes in platelets. The relationship between altered platelet functions and thrombotic and inflammatory disorders in older adults is highlighted. Established and developing anti-platelet therapies for the treatment of thrombotic and inflammatory disorders are also discussed in light of these data.

Background The lifetime risk of heart failure is higher in the African-American population than in other racial groups in the United States. Methods and Results We measured the Life’s Simple 7 ideal cardiovascular health metrics in 4195 African-Americans in the Jackson Heart Study (2000–2004). We evaluated the association of Simple 7 metrics with incident HF and left ventricular (LV) structure and function by cardiac magnetic resonance (CMR; n=1188). Mean age at baseline was 54.4 years (65% women). Relative to 0–2 Simple 7 factors, African-Americans with 3 factors had 47% lower incident HF risk (HR 0.53, 95% CI 0.39–0.73, P<0.0001); those with ≥ 4 factors had 61% lower HF risk (HR 0.39, 95% CI 0.24–0.64, P=0.0002). Higher blood pressure (HR 2.32, 95% CI 1.28–4.20, P=0.005), physical inactivity (HR 1.65, 95% CI 1.07–2.55, P=0.02), smoking (HR 2.04, 95% CI 1.43–2.91, P<0.0001) and impaired glucose control (HR 1.76, 95% CI 1.34–2.29, P<0.0001) were associated with incident HF. The age-/sex-adjusted population attributable risk for these Simple 7 metrics combined was 37.1%. Achievement of ideal blood pressure, ideal body mass index, ideal glucose control, and non-smoking was associated with less likelihood of adverse cardiac remodeling by CMR. Conclusions Cardiovascular risk factors in mid-life (specifically elevated blood pressure, physical inactivity, smoking and poor glucose control) are associated with incident HF in African Americans, and represent targets for intensified HF prevention.

The incidence of heart failure (HF) remains high and patients with HF are at risk for frequent hospitalisations. Remote monitoring technologies may provide early indications of HF decompensation and potentially allow for optimisation of therapy to prevent HF hospitalisations. The need for reliable remote monitoring technology has never been greater as the COVID-19 pandemic has led to the rapid expansion of a new mode of healthcare delivery: the virtual visit. With the convergence of remote monitoring technologies and reliable method of remote healthcare delivery, an understanding of the role of both in the management of patients with HF is critical. In this review, we outline the evidence on current remote monitoring technologies in patients with HF and highlight how these advances may benefit patients in the context of the current pandemic.

Gemcitabine is a commonly used antineoplastic agent used to treat a variety of cancers with rarely reported cardiac side effects. We describe a case of a 67‐year‐old woman with follicular lymphoma who experienced a rarely reported side effect of gemcitabine: cardiomyopathy. This case highlights a multiple hit mechanism of myocyte damage that may occur following the use of multiple cardio‐toxic agents despite their administration in doses not associated with cardiotoxicity.
