Negative cardiovascular health indicators were found to be higher in children with hemophilia A, compared with healthy children, according to a small research study.
Biochemical, imaging, and metabolic analyses were performed to compare 17 boys with severe hemophilia A to 23 healthy boys designated as controls.
The myocardial performance index (MPI) was evaluated using tissue Doppler echocardiography. In addition, peripheral and central blood pressure and arterial stiffness were assessed, as were carotid intima–media thicknesses (CIMTs), serum glucose, insulin, insulin resistance, and lipoprotein levels.
Increased MPI is considered an indicator of global deterioration in myocardial functions.
There were no differences between the two groups in terms of age and biochemical parameters, according to the researchers. There were also no significant differences found between the groups in terms of CIMT, peripheral blood pressure, and central systolic blood pressure.
However, the HDL cholesterol levels in the hemophilia group were significantly lower than those in the control group (P < .05). Five of the hemophilia patients had insulin resistance (29.4%), whereas four had low HDL cholesterol levels (23.5%).
The researchers found that the MPI values in the hemophilia group were higher than those in the control group (0.41 vs. 0.34; P = .004). In addition, left ventricle ejection time (ET), which is a predictor of mortality in heart failure and ischemic heart disease, was shorter in the hemophilia group than it was in the control group (266.6 vs. 284.4; P = .014).
As arterial stiffness increases, ejection time decreases owing to the deteriorating myocardial systolic functions, and it has also been reported in the literature that arterial stiffness affects left ventricular systolic functions, according to the authors.
“Arterial stiffness and high [central diastolic blood pressure] developing in patients with severe hemophilia A since their childhood are important risk factors for coronary artery diseases. Predisposition to dyslipidemia and [insulin resistance] noted in the hemophilia group also negatively contributes to this process. Adolescent patients with hemophilia should be monitored for hypertension, obesity, dyslipidemia, and [insulin resistance],” the authors concluded.
The study received no external funding. The authors did not report disclosures.
