OBJECTIVE: Right ventricle and pulmonary artery pressure have always received less attention in type 1 diabetes than left ventricle. The aim of this study is to compare the right heart performance and the estimated peak systolic pulmonary artery pressure (EPSPAP) in young type 1 diabetes patients with healthy controls.PATIENTS AND METHODS: Subjects affected by type 1 diabetes without cardiovascular and respiratory diseases (n=93) and healthy controls (n=56) were evaluated with a comprehensive transthoracic echocardiography. The pulmonary peak systolic arterial pressure was calculated with an established formula based on pulmonary artery acceleration time.RESULTS: The left ventricle's function was found to be normal in all the subjects under study. The estimated peak systolic pulmonary artery pressure was significantly higher in patients with type 1 diabetes compared to the controls (38.5 +/- 8.6 vs. 35.4 +/- 6.7, p =0.019). The highest value of EPSPAP was observed in smoking female patients with type 1 diabetes. Basal and mid cavity diameter of the right ventricle were higher in patients with type 1 diabetes. Factors associated with EPSPAP were sex, body mass index, mid cavity diameter and, with an inverse correlation, HDL-cholesterol.CONCLUSIONS: The present study suggests that young, uncomplicated patients with type 1 diabetes have a higher estimated peak systolic pulmonary artery pressure. Further studies are needed to define the mechanisms underlying this alteration and its clinical consequences.

Abstract

OBJECTIVE: Right ventricle and pulmonary artery pressure have always received less attention in type 1 diabetes than left ventricle. The aim of this study is to compare the right heart performance and the estimated peak systolic pulmonary artery pressure (EPSPAP) in young type 1 diabetes patients with healthy controls.PATIENTS AND METHODS: Subjects affected by type 1 diabetes without cardiovascular and respiratory diseases (n=93) and healthy controls (n=56) were evaluated with a comprehensive transthoracic echocardiography. The pulmonary peak systolic arterial pressure was calculated with an established formula based on pulmonary artery acceleration time.RESULTS: The left ventricle's function was found to be normal in all the subjects under study. The estimated peak systolic pulmonary artery pressure was significantly higher in patients with type 1 diabetes compared to the controls (38.5 +/- 8.6 vs. 35.4 +/- 6.7, p =0.019). The highest value of EPSPAP was observed in smoking female patients with type 1 diabetes. Basal and mid cavity diameter of the right ventricle were higher in patients with type 1 diabetes. Factors associated with EPSPAP were sex, body mass index, mid cavity diameter and, with an inverse correlation, HDL-cholesterol.CONCLUSIONS: The present study suggests that young, uncomplicated patients with type 1 diabetes have a higher estimated peak systolic pulmonary artery pressure. Further studies are needed to define the mechanisms underlying this alteration and its clinical consequences.
