Abstract

Subclinical left ventricular (LV) myocardial dysfunction is associated with an increased risk of cardiovascular disease (CVD), but it is not known whether subclinical LV myocardial dysfunction is present in patients with ankylosing spondylitis (AS) independent of CVD risk factors. Conventional and speckle tracking echocardiography were performed in 106 patients with AS (mean ± SD age 48 ± 12 years; 59% men) and 106 matched controls (mean ± SD age 51 ± 12 years; 59% men). LV systolic myocardial function was assessed by peak systolic global longitudinal strain (GLS). CVD risk factors were similarly distributed in patients with AS and controls, but more controls received statin therapy (P = 0.05). GLS was significantly lower in patients with AS compared to controls (mean ± SD -17.7 ± 2.5% versus -18.4 ± 2.3%; P = 0.03). In univariable linear regression analyses in the total study population, lower GLS was associated with having AS, male sex, higher body mass index, higher LV mass index, and lower LV ejection fraction (all P < 0.05). Having AS retained an independent association with lower GLS when adjusted for these factors in multivariable analyses (β = 0.16, P = 0.02). In patients with AS, lower GLS was independently associated ...Continue Reading

Angelman Syndrome

Angelman syndrome is a neurogenetic imprinting disorder caused by loss of the maternally inherited UBE3A gene and is characterized by generalized epilepsy, limited expressive speech, sleep dysfunction, and movement disorders. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
