Key result
Mechanical circulatory support alters systemic physiology across 7 age-specific domains and warrants consideration despite advanced age.
Why the study?
In elderly and senile patients, the systemic circulatory remodeling caused by mechanical circulatory support occurs against a background of age-related vascular stiffness, endothelial dysfunction, chronic inflammation, multimorbidity, frailty, and reduced organ reserve.
This review proposes a clinical and pathophysiological framework for assessing elderly patients for mechanical circulatory support, emphasizing that calendar age alone should not exclude patients from therapy.

Biological reserve over chronological age should guide MCS decisions in elderly patients; leaves open prospective validation of frailty-based selection criteria.
The review discusses pathophysiological features of mechanical circulatory support while using biotechnical and medical systems in elderly and senile patients. The focus is not on technical characteristics of devices, but on systemic circulatory remodeling caused by temporary or durable support: changes in left and right ventricular loading, ventriculoarterial coupling, pulsatility, microcirculation, hemostasis, inflammatory response, renal function and cerebral perfusion. In older patients these effects occur against the background of vascular stiffness, endothelial dysfunction, chronic inflammation of aging, multimorbidity, sarcopenia, frailty, chronic kidney disease and reduced cognitive reserve. The scientific novelty of the review is the identification of age-specific pathophysiological contours of mechanical circulatory support: macrohemodynamic, microcirculatory-endothelial, right ventricular-pulmonary, hemocompatibility, cardiorenal, neurocerebral and geriatric. The article presents that calendar age alone should not be used as the criterion for withholding therapy. Decision-making should integrate reversibility of organ hypoperfusion, right ventricular-pulmonary reserve, frailty severity, cognitive status and expected functional recovery. A clinical and pathophysiological logic for assessing a patient before temporary or long-term mechanical circulatory support is proposed.

Kozlov et al. (2026) conducted a review in Cardiovascular conditions requiring temporary or durable mechanical circulatory support in elderly and senile patients. Mechanical circulatory support using biotechnical and medical systems was evaluated. Mechanical circulatory support in elderly patients causes systemic circulatory remodeling across seven age-specific pathophysiological contours and should not be withheld based on calendar age alone.
