摘要

Background and aims

Endogenous Cushing's syndrome (CS) is characterized by an unfavorable cardiovascular (CV) and metabolic risk profile, but the potential adverse effects of hypercortisolism on myocardial function are not well known. Myocardial Work analysis is a new echocardiographic method that utilizes left ventricular pressure-strain loops to quantify cardiac performance independent of afterload.

Methods and results

In a cross-sectional analysis, we compared four groups: patients with overt endogenous CS (n = 31, mean age 47 ± 12 years, 71% women), patients with endogenous CS in long-term remission after medical cure (CS-LTR; n = 49, 53 ± 12 years, 78% women), healthy subjects (n = 439; 49 ± 11 years, 57% women), and individuals with metabolic syndrome (n = 305, 59 ± 10 years, 37% women). Both CS patient groups exhibited a CV risk pattern and metabolic profile worse than healthy subjects but better than individuals with metabolic syndrome. Analyses adjusted for sex and age revealed higher Wasted Work both in overt CS (median; quartiles: 105 mmHg%; 74, 147) and CS-LTR (97 mmHg%; 69, 158), respectively, when compared to healthy individuals (75 mmHg%; 54, 109, p < 0.01) or individuals with metabolic syndrome (95 mmHg%, 65, 136, p < 0.05), resulting in compromised Work Efficiency (p < 0.05).

Conclusion

Left ventricular performance is compromised in overt CS beyond alterations found in individuals with metabolic syndrome sharing equal CV risk factors and remains so despite biochemical remission during the LTR period. Myocardial Work analysis is suited to detect the subtle yet clinically relevant differences between different phenotypes of myocardial involvement.
