Left ventricular mechanics and oxygen demand in patients with severe obesity undergoing Roux-en-Y gastric bypass surgery
Grymyr, Lisa Marie Dale (Doctoral thesis, 2024-11-29)Bakgrunn og mål: Venstre ventrikkel (VV) er eksponert for kronisk trykk- og volumoverbelastning ved alvorlig fedme. Effekten av vektreduserende kirurgi på fedme-relatert VV-dysfunksjon har ikke vært kartlagt i detalj ... -
Markers of Subclinical Atherosclerosis in Severe Obesity and One Year after Bariatric Surgery
Kovac, Nina; Grymyr, Lisa Marie Dale; Gerdts, Eva; Nadirpour, Saied; Nedrebø, Bjørn Gunnar; Hjertaas, Johannes Just; Matre, Knut; Cramariuc, Dana (Journal article; Peer reviewed, 2022)Background: Aortic valve sclerosis (AVS), mitral valve sclerosis (MVS), remodeling of major arteries, and increased pericardial fat are associated with subclinical atherosclerosis. We assessed these markers of atherosclerosis ... -
One-year impact of bariatric surgery on left ventricular mechanics: results from the prospective FatWest study
Grymyr, Lisa Marie Dale; Nadirpour, Saied; Gerdts, Eva; Nedrebø, Bjørn Gunnar; Hjertaas, Johannes Just; Matre, Knut; Cramariuc, Dana (Journal article; Peer reviewed, 2021)Aims: Patients with severe obesity are predisposed to left ventricular (LV) hypertrophy, increased myocardial oxygen demand, and impaired myocardial mechanics. Bariatric surgery leads to rapid weight loss and improves ... -
Preoperative risk factors associated with left ventricular dysfunction after bariatric surgery
Grymyr, Lisa Marie Dale; Mellgren, Gunnar; McCann, Adrian; Gerdts, Eva; Meyer, Klaus; Nadirpour, Saied; Fernø, Johan; Nedrebø, Bjørn Gunnar; Cramariuc, Dana (Journal article; Peer reviewed, 2024)A large proportion of patients with severe obesity remain with left ventricular (LV) dysfunction after bariatric surgery. We assessed whether preoperative evaluation by echocardiography and inflammatory proteins can identify ... -
Sex differences in left atrial volumes, mechanics, and stiffness in primary mitral regurgitation - a combined 2D and 3D echocardiographic study
Berg-Hansen, Christian Engelsen; Sindre, Rasmus Bach; Grymyr, Lisa Marie Dale; Rogge, Barbara; Valeur, Andreas Egeli; Urheim, Stig; Hung, Judy; Cramariuc, Dana (Journal article; Peer reviewed, 2024)Aims Mitral regurgitation (MR) causes left atrial (LA) enlargement and impaired reservoir function. We assessed whether changes in LA size, strain, and stiffness in significant (moderate or greater) primary MR are ...
