Demonstration of Subclinical Left Ventricular Electrical and Mechanical Dysfunction in Overweight Subjects by Frontal Qrs-T Angle and 3d-Speckle Tracking Echocardiography
(Wiley, 2023) Mammadov, G.; Taşkın, Uğur; Dindaş, Ferhat; Doğduş, Mustafa
BackgroundOverweightness is a considerable step in the process leading to obesity. There are no sufficient studies on the effect of cardiomyopathy defined in obese patients about overweight subjects. We thought that it may be useful to examine the myocardial involvement in overweight individuals electro-mechanically with more sensitive techniques before the development of obesity cardiomyopathy. AimThe aim of the present study was to demonstrate whether or not there are subclinical left ventricular (LV) electrical and mechanical dysfunctions in overweight patients using frontal QRS-T (fQRS-T) angle (electrically) and 3D-speckle tracking echocardiography (mechanically). MethodsA total of 80 overweight patients and 80 age- and sex-matched normal weight individuals were enrolled into the study. 3D-STE examinations of the patients were performed. Electrocardiographic recordings were obtained for fQRS-T angle assessment. ResultsThe LV-GLS and LV-GCS were significantly depressed in the overweight group than in the normal weight group (-14.5 & PLUSMN; 3.4 vs. -21.7 & PLUSMN; 3.6, p < .001; -15.2 & PLUSMN; 4.6 vs. -24.3 & PLUSMN; 4.8, p < .001, respectively). The fQRS-T angle was found to be increased in the overweight group (142.5 & PLUSMN; 39.2 vs. 114.7 & PLUSMN; 43.5, p = < .001). Statistically significant positive linear correlations were observed between BMI with LV-GLS, LV-GCS, and fQRS-T angle. LV-GLS and LV-GCS were found to be disrupted linearly as BMI increased (r = .718 for BMI and LV-GLS, r = .653 for BMI and LV-GCS). As BMI increased, it was found that the fQRS-T angle increased (r = .692 for BMI and fQRS-T angle). ConclusionOur results support that, overweight individuals, despite their being apparently healthy, may have subclinical LV myocardial mechanical and electrical dysfunction.

Evaluation of Left Atrial and Left Ventricular Functions With 3d Speckle-Tracking Echocardiography in Patients With Coronary Artery Tortuosity
(John Wiley and Sons Inc, 2023) Taskin, U.; Mammadov, G.; Topaloğlu, Caner; Koyuncu, I.; Doğduş, Mustafa
Background: Tortuosity in the coronary arteries is a very common entity encountered during angiography. The effect of coronary artery tortuosity (CAT) on the myocardium has not been completely investigated. The aim of the current study was to assess the effects of CAT on left atrial (LA) and left ventricular (LV) myocardial functions by 3D speckle-tracking echocardiography (3D-STE). Methods: Seventy-five patients with CAT and 80 age- and gender-matched controls who proved to have normal coronary angiograms (CAG) were enrolled into the study. Following CAG, the 2D images were obtained first, and then 3D images were obtained for strain analysis. Results: The LAS-r, LAS-active, and LV-GLS were significantly depressed in the CAT (+) group (p <.001, p <.001, p =.012, respectively). The multivariate regression models demonstrated that LAS-r (p <.001), LAS-active (p =.009), and LV-GLS (p =.024) were found to be independent factors predicting CAT. Conclusion: The current study is the first to focus on the assessing both LA and LV myocardial dynamics in CAT (+) patients by strain echocardiography. The results of our study support the patients with CAT may have subclinical LA and LV myocardial involvements. © 2023 Wiley Periodicals LLC.
