Insights
Sickle cell anemia patients with eccentric hypertrophy show the lowest survival rates. Early cardiac disorder detection and treatment are crucial for reducing mortality in sickle cell cardiomyopathy.
Area of Science:
- Cardiology
- Hematology
- Medical Imaging
Background:
- Sickle cell anemia (SCA) is a prevalent hemoglobinopathy globally.
- Cardiovascular diseases are the leading cause of mortality in SCA patients.
- Cardiac remodeling, including hypertrophy, develops early and leads to sickle cell cardiomyopathy.
Purpose of the Study:
- To determine the relationship between cardiac remodeling types and survival in SCA patients.
- To identify factors influencing left ventricular mass in SCA.
- To investigate the prognostic value of different cardiac remodeling patterns.
Main Methods:
- Echocardiographic measurements of left ventricular mass index (LVMI) and relative wall thickness (RWT).
- Categorization of 146 SCA patients into normal, concentric remodeling (CR), concentric hypertrophy (CH), and eccentric hypertrophy (EH) groups.
- Logistic regression analysis to identify predictors of LVMI.
Main Results:
- Hemoglobin S (HbS) and ferritin levels independently predicted LVMI.
- Prevalence of remodeling types: normal (38.4%), CR (16.4%), CH (14.4%), EH (30.8%).
- Overall mortality was 21.2%, with EH patients exhibiting significantly lower survival rates (log-rank p < 0.001).
Conclusions:
- Cardiac death is a major cause of mortality in SCA.
- Eccentric hypertrophy is associated with the poorest survival outcomes.
- Early detection and management of cardiac abnormalities are vital for improving survival in SCA patients.
Abstract:
Introduction and aim Sickle cell anemia (SCA) is the most common hemoglobinopathy worldwide, and cardiovascular diseases are the most common causes of death. In these patients, cardiac remodeling begins from childhood and leads to sickle cell cardiomyopathy in the following years. Concentric hypertrophy and eccentric hypertrophy are known to predict early cardiac events. This study aims to reveal the relationship between cardiac remodeling types and survival in patients with SCA and investigate the factors that may affect left ventricular mass. Materials and methods A total of 146 patients with SCA were included in the study, and the left ventricular mass index (LVMI) and relative wall thickness (RWT) of the patients were calculated according to echocardiographic measurements, and the patients were categorized into normal, concentric remodeling (CR), concentric hypertrophy (CH), and eccentric hypertrophy (EH) groups. Results The median age of the patients is 32 (18-72). In logistic regression analysis, hemoglobin S (HbS) and ferritin levels were independent predictors for LVMI (p = 0.01 and p < 0.001, respectively). It was observed that 56 (38.4%) of the patients had normal left ventricles, 24 (16.4%) had CR, 21 (14.4%) had CH, and 45 (30.8%) had EH. 31 (21.2%) of the patients died. When we look at the survival curves, there was a statistically significant difference between the four groups (log-rank p < 0.001). It was observed that patients with EH were the group with the lowest probability of survival. Conclusion Cardiac death is one of the most common causes of death in patients with SCA. Early detection of cardiac disorders and starting treatment may be important in reducing mortality in these patients.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
