In a contemporary community population with chronic heart failure, non-cardiac co-morbidities confer a similar contribution to outcomes in HFrEF and HFpEF. These observations suggest that quality improvement initiatives aimed at optimizing co-morbidities may be similarly effective in HFrEF and HFpEF.

The interplay between cardiac function and arterial system, which in turn affects ventricular performance, is defined commonly ventricular-arterial coupling and is an expression of global cardiovascular efficiency. This relation can be expressed in mathematical terms as the ratio between arterial elastance (EA) and end-systolic elastance (EES) of the left ventricle (LV). The noninvasive calculation requires complicated formulae, which can be, however, easily implemented in computerized algorithms, allowing the adoption of this index in the clinical evaluation of patients. This review summarizes the up-to-date literature on the topic, with particular focus on the main clinical studies, which range over different clinical scenarios, namely hypertension, heart failure, coronary artery disease, and valvular heart disease.

Socioeconomic and lifestyle factors, particularly cultural fruition, are associated with frailty independently from functional impairment and low physical activity. Cultural habits may therefore represent a new target of multimodal interventions against geriatric frailty.
