    Purpose Patients with vitamin D deficiency (VDD) have potential to have increased cardiovascular morbidity and mortality. In this study, we aimed to discover the findings of early atherosclerosis in patients with VDD by measuring carotid intima-media thickness (CIMT) and epicardial fat thickness (EFT). Materials and Methods The study population includes 52 patients with VDD (n = 30 [57% female], mean +/- SD age 54.28 +/- 8.77 years, mean +/- SD serum 25-hydroxyvitamin D (25 [OH] D) 11 +/- 2.4 ng/mL) and 82 participants for control group (n = 52 [63.4% female], mean +/- SD age 56.40 +/- 7.90 years, mean +/- SD serum (25 [OH] D) 53 +/- 4.2 ng/mL) who have no cardiovascular disease. Carotid intima-media thickness was assessed by using ultrasonography, and EFT was measured on the free wall of the right ventricle at end diastole from the parasternal long-axis views by standard transthoracic 2-dimensional echocardiography. Results Both CIMT and EFT were significantly higher in patients with VDD compared with controls (0.75 +/- 0.16 mm vs 0.68 +/- 0.21 mm, P < 0.05, and 0.66 +/- 0.15 cm vs 0.56 +/- 0.15 cm, P < 0.001). Conclusions Patients with VDD seem to have increased CIMT and EFT, which are predictors of atherosclerotic process. Further studies are needed to confirm these results.

    Parathyroid Hormone and Ischemic Cerebrovascular Event
    (2019) Altay, Hakan; Altin, Cihan; Coner, Ali; Muderrisoglu, Haldun; Giray, Semih; 0000-0002-9635-6313; 0000-0002-0722-3181; 30806331; AAG-8233-2020; AAH-1091-2020
    Background: Increased parathyroid hormone (PTH) level is associated with coronary artery disease, hypertension and left ventricular hypertrophy which are all predisposing factors for the ischemic cerebrovascular event ( ICVE). Carotid intima-media thickness (CIMT) and aortic distensibility are the two early, subclinical predictors of atherosclerosis. The relation of PTH with CIMT and aortic distensibility in patients with ICVE has not been previously studied. Objective: Our aim was to study the relationship of PTH levels with aortic distensibility and CIMT in patients with ICVE. Methods: Sixty-four ICVE patients and 50 control group were enrolled in the study. PTH levels, aortic distensibility and CIMT were measured in all individuals. Results: PTH levels were significantly higher in ICVE patients than in the controls (60.1 +/- 21.6 vs. 52.3 +/- 6.2 pg/ml) (p=0. 008). PTH levels were found to be inversely correlated with aortic distensibility (r= -0. 420, p=0.001) and positively correlated with CIMT ( r:0, 285, p=0,002). Conclusion: The present study shows that PTH levels are increased in patients with acute ischemic cerebrovascular event compared to the control group. It also demonstrates that PTH levels are inversely related to aortic distensibility of ascending aorta and positively associated with CIMT.
