Subclinical cardiovascular parameters not associated with dizziness, vertigo
Dizziness and vertigo appear to be not associated with subclinical carotid structure and left and right ventricular function, reveals a new study.
On the other hand, subclinical cerebrum measurements may increase the risk of dizziness and vertigo in diabetics and males.
The lifetime prevalence of dizziness and vertigo in a sample of 400 adults without confirmed stroke, myocardial infarction or arterial vessel occlusion was 30 percent. White matter lesions (13.7 vs 11.2 percent; p=0.482) and cerebral microbleeds (15.4 vs 11.7 percent; p=0.314) were marginally more prevalent in those with dizziness and vertigo than in those without.
In multivariable adjusted logistic regression models, cardiovascular phenotypes shown in magnetic resonance imaging were not significantly associated with dizziness and vertigo.
Ejection fractions for the left (odds ratio [OR], 0.93; 95 percent CI, 0.74 to 1.17; p=0.560) and right (OR, 0.99; 0.76 to 1.29; p=0.944) ventricles, for instance, were not significantly associated with lifetime prevalence of dizziness and vertigo.
Similarly, lifetime prevalence was not significantly correlated with mean carotid wall thickness (OR, 1.07; 0.81 to 1.4; p=0.645) and presence of plaques (OR, 0.50; 0.24 to 1.02; p=0.058).
The presence of white matter lesions (OR, 1.26; 0.63 to 2.49; p=0.512) and cerebral microbleeds (OR, 1.40; 0.72 to 2.70; p=0.319) yielded the highest ORs for lifetime dizziness and vertigo. These values did not reach significance.
Furthermore, sensitivity analysis showed that the 12-month dizziness and vertigo was significantly associated with white matter lesions only in males (OR, 2.95; 1.08 to 8.07).
