Key result
Ischemic cerebrovascular events are linked to ~15% higher parathyroid hormone levels compared to controls.
Why the study?
Increased PTH is linked to cardiovascular risk factors for ischemic cerebrovascular event (ICVE), but its relationship with CIMT and aortic distensibility in ICVE patients had not been studied.
Are parathyroid hormone levels associated with aortic distensibility and carotid intima-media thickness in patients with ischemic cerebrovascular events?

Are parathyroid hormone levels associated with aortic distensibility and carotid intima-media thickness in patients with ischemic cerebrovascular events?
Parathyroid hormone levels are elevated in patients with acute ischemic cerebrovascular events and correlate with subclinical markers of atherosclerosis, including increased carotid intima-media thickness and reduced aortic distensibility.
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.

Altay et al. (2019) conducted a case-control in Ischemic Cerebrovascular Event (n=114). Ischemic Cerebrovascular Event vs. Control group was evaluated on Parathyroid hormone (PTH) levels (p=0.008). Patients with an ischemic cerebrovascular event had significantly higher parathyroid hormone levels compared to controls (60.1 vs. 52.3 pg/ml, p=0.008).
