Abstract

The aim of this study was to examine the cardiac effects of anthracycline therapy based on speckle-tracking echocardiography (STE) and to identify patients at risk for cardiotoxicity. The study included 35 breast cancer (BC) and 15 lymphoma patients who were treated with anthracycline-based chemotherapy. Conventional echocardiography and STE were performed 1 month prior to and 1 month after chemotherapy. Longitudinal strain analysis was performed via STE using automated functional imaging. The ejection fraction (EF) and the fractional shortening values were significantly lower in the lymphoma group. There was a positive correlation between anthracycline dose and subclinical heart failure (p = 0.024). There was an increase in the myocardial performance index in both groups. After therapy, STE showed regional decreases in the longitudinal strain values in the BC group, but the global strain values did not differ. In the lymphoma group, the apical long-axis, the 4-chamber, and the global longitudinal strain values were significantly lower after therapy (p = 0.002, 0.041, and 0.004, respectively). The long-axis and global longitudinal strain values were significantly lower in the lymphoma patients with normal EF values (p = 0.01 an...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

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.
