Concentric left ventricular hypertrophy in patients with Takayasu arteritis

Y HashimotoF Numano


Although aortic regurgitation (AR) in patients with Takayasu arteritis (TA) is believed to be caused by dilatation of the aortic ring or thickening of the aortic cusps, the pattern of left ventricular hypertrophy (LVH) in these patients has not been described. To clarify the geometry of the LV in patients with TA that had been documented both echocardiographically and hemodynamically, the authors evaluated 22 patients with TA and severe AR (group 1), 10 with TA and systemic hypertension (group 2), and 17 with isolated severe AR of other etiologies (group 3). M-mode echocardiography showed that LV dimensions were smaller in groups 1 and 2 than in group 3 and that wall thickness was greater in group 1 than in group 3. The concentric hypertrophic ratio (CHR = wall thickness/LV end-diastolic dimension+wall thickness) was larger than group 1 (p < 0.001) and group 2 (p < 0.01) than in group 3. CHR was similar in groups 1 and 2. Systolic blood pressure was significantly increased in group 2 and showed a tendency to increase in group 1 as compared with group 3. The results confirmed the presence of concentric LVH related to a pressure overload in patients with TA, even when TA was complicated by severe AR.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging
