Noncompaction cardiomyopathy (NCCM) is characterized by hypertrabeculation of the LV endomyocardial wall, with an underdeveloped endocardial helix. This may result in absence of LV twist, disturbed aortic elasticity, LV dysfunction, and ultimately premature heart failure (HF). This study compared the aortic stiffness and clinical outcome in patients with NCCM to that of a control group with dilated cardiomyopathy (DCM). Sixty NCCM patients, matched by age and sex, were compared with 60 DCM controls. Transthoracic echocardiography was performed to measure the systolic (SD) and diastolic diameters (DD) of the ascending aorta. These measurements, along with systolic (SBP) and diastolic blood pressure (DBP), were utilized to calculate the aortic stiffness index defined as ln(SBP\/DBP)\/[(SD-DD)\/DD]. This index was then compared to clinical features and outcome. The mean age was 49 \u00b1 16 years (55% males) in the NCCM group and 49 \u00b1 16 years (55% male) in the DCM group. Aortic stiffness index (ASI) was significantly higher in the NCCM group than in the DCM group (7.0 [5.8\u201310.2] vs. 6.2 [4.8\u20137.7], p = 0.011). This difference remained statistically significant after adjustment for established risk factors associated with aortic stiffness (\u03b2 = 1.771; 95% CI [0.253\u20133.289], p = 0.023). Patients with NCCM demonstrated increased aortic stiffness when compared to those with DCM, which may reflect the underlying pathophysiological processes. Additional research is necessary to evaluate the impact of aortic stiffness on the advancement of LV dysfunction, the onset of heart failure, and long-term outcomes.<\/jats:p>","DOI":"10.3390\/jcdd12080303","type":"journal-article","created":{"date-parts":[[2025,8,11]],"date-time":"2025-08-11T14:32:36Z","timestamp":1754922756000},"page":"303","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Decreased Aortic Elasticity in Noncompaction Cardiomyopathy Compared to Dilated Cardiomyopathy"],"prefix":"10.3390","volume":"12","author":[{"given":"Martijn","family":"Tukker","sequence":"first","affiliation":[{"name":"Department of Cardiology, Office RG-431, Thoraxcenter, Cardiovascular Institute, ErasmusMC University Medical Center, Dr. Molewaterplein 40, 3015 GD Rotterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0323-5118","authenticated-orcid":false,"given":"Sharida","family":"Mohamedhoesein","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Office RG-431, Thoraxcenter, Cardiovascular Institute, ErasmusMC University Medical Center, Dr. Molewaterplein 40, 3015 GD Rotterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emrah","family":"Kaya","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Reinier de Graaf Hospital, Reinier de Graafweg 5, 2625 AD Delft, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arend F.L.","family":"Schinkel","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Office RG-431, Thoraxcenter, Cardiovascular Institute, ErasmusMC University Medical Center, Dr. Molewaterplein 40, 3015 GD Rotterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kadir","family":"Caliskan","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Office RG-431, Thoraxcenter, Cardiovascular Institute, ErasmusMC University Medical Center, Dr. Molewaterplein 40, 3015 GD Rotterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"754","DOI":"10.1016\/S0895-7061(02)02966-7","article-title":"Prognostic application of arterial stiffness: Task forces","volume":"15","author":"London","year":"2002","journal-title":"Am.
