Global longitudinal strain impairment was detected in 47.5% of stable liver transplant recipients despite preserved ejection fraction, and remained unchanged at 12 months.
Cross-Sectional (n=40)
Global longitudinal strain detects subclinical myocardial dysfunction in nearly half of stable liver transplant recipients with preserved ejection fraction.
Liver transplant (LT) recipients represent a population at elevated cardiovascular (CV) risk, yet conventional assessment tools often fail to capture early myocardial dysfunction. Global longitudinal strain (GLS) has emerged as a sensitive marker of subclinical myocardial dysfunction, although its role in the long-term post-transplant setting remains poorly defined. The study aimed to evaluate left ventricular (LV)-GLS in a population of stable LT recipients with a mild cardiometabolic burden and to explore possible associations with metabolic, lifestyle, inflammatory, and transplant-related variables. A secondary aim was to assess longitudinal GLS variation over a 12-month period. We conducted a cross-sectional observational study in 40 LT recipients. Cardiometabolic parameters, body composition (including bioimpedance analysis), diet (Medi-Lite), physical activity (IPAQ), echocardiography, and levels of circulating inflammatory cytokines were measured. CV risk scores were calculated. GLS impairment was detected in 47.5% of patients, despite preserved ejection fraction. Antihypertensive therapy correlated with more favorable GLS, whereas higher IL-17A and IL-1β levels were paradoxically linked to preserved strain. No association was found with immunosuppressive regimen or lifestyle indices. GLS remained unchanged at 12 months, irrespective of weight loss or dietary improvement. GLS appears more sensitive than EF in detecting subclinical myocardial dysfunction in LT recipients, highlighting its potential role in post-transplant CV surveillance. Antihypertensive treatment may exert protective effects, whereas cytokine patterns suggest unconventional mechanisms of cardiac modulation. Larger longitudinal studies are needed to confirm prognostic implications and integrate GLS into CV risk stratification pathways post-LT.
Toscano et al. (Fri,) conducted a cross-sectional in Liver transplant (n=40). Liver transplant was evaluated on Global longitudinal strain (GLS) impairment. Global longitudinal strain impairment was detected in 47.5% of stable liver transplant recipients despite preserved ejection fraction, and remained unchanged at 12 months.
