The effect of acromegaly treatment on LV systolic function assessed by STE, has not been evaluated so far.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and methods<\/jats:title><jats:p>Thirty-two na\u00efve acromegalic patients without detectable heart disease were enrolled in a prospective, single-center study. 2D-Echocardiography and STE were performed at diagnosis, 3&amp;amp;6 months on preoperative somatostatin receptor ligand (SRL) treatment and 3 months after transsphenoidal surgery (TSS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Treatment with SRL resulted in reduction in median (IQR) GH&amp;amp;IGF-1 levels after 3 months, from 9.1(3.2-21.9) to 1.8(0.9-5.2) ng\/mL (p&amp;lt;0.001) and from 3.2(2.3-4.3) to 1.5(1.1-2.5) xULN (p&amp;lt;0.001), respectively. Biochemical control on SRL was achieved in 25.8% of patients after 6 months and complete surgical remission was achieved in 41.7% of patients. TSS resulted in decrease in median (IQR) IGF-1 compared to IGF-1 levels on SRL treatment: from 1.5(1.2-2.5) to 1.3(1.0-1.6) xULN (p=0.003). Females had lower IGF-1 levels at baseline, on SRL and after TSS compared to males. The median end diastolic and end systolic left ventricle volumes were normal. Almost half of the patients (46.9%) had increased LVMi, however the median value of LVMi was normal in both sex groups: 99g\/m<jats:sup>2<\/jats:sup> in males and 94g\/m<jats:sup>2<\/jats:sup> in females. Most patients (78.1%) had increased LAVi and the median value was 41.8mL\/m<jats:sup>2<\/jats:sup>. At baseline 50% of patients, mostly men (62.5% vs. 37.5%) had GLS values higher than -20%. There was a positive correlation between baseline GLS and BMI r=0.446 (p=0.011) and BSA r=0.411 (p=0.019). The median GLS significantly improved after 3 months of SRL treatment compared to baseline: -20.4% vs. -20.0% (p=0.045). The median GLS was lower in patients with surgical remission compared to patients with elevated GH&amp;amp;IGF-1 levels: -22.5% vs. -19.8% (p=0.029). There was a positive correlation between GLS and IGF-1 levels after TSS r=0.570 (p=0.007).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The greatest beneficial effect of acromegaly treatment on LV systolic function is visible already after 3 months of preoperative SRL treatment, especially in women.
