[Myocardial function in patients with hereditary hemochromatosis based on echocardiographic data]
Insights
Hereditary hemochromatosis (HHC) patients over 35 show preclinical heart failure signs. Echocardiography revealed left ventricular enlargement and reduced pump function in these HHC individuals.
Area of Science:
- Cardiology
- Genetics
- Internal Medicine
Background:
- Hereditary hemochromatosis (HHC) is an iron overload disorder.
- Early detection of cardiac involvement in HHC is crucial for preventing heart failure.
- Myocardial changes can occur at preclinical stages.
Purpose of the Study:
- To identify preclinical myocardial changes in patients with hereditary hemochromatosis.
- To assess cardiac function using echocardiography in HHC patients.
Main Methods:
- M-mode echocardiography was performed on 34 HHC patients (26 men, 8 women, aged 24-59).
- A control group of 20 healthy individuals was included.
- Cardiac parameters were analyzed, focusing on patients over 35 years old.
Main Results:
- HHC patients over 35 years old (average age 49.5) exhibited left ventricular cavity enlargement.
- Increased thickness of the interventricular septum and posterior heart wall was observed.
- A reduction in left ventricular pump function was evident in older HHC patients.
Conclusions:
- HHC is associated with preclinical cardiac changes, including structural and functional alterations.
- Echocardiography can detect early signs of heart failure in HHC patients.
- Timely intervention may be necessary to manage cardiac complications in HHC.
Abstract:
In order to reveal changes in the myocardium at the preclinical stage of heart failure, 34 patients with hereditary hemochromatosis (HHC) underwent echocardiography in the M-mode. There were 26 men and 8 women aged 24 to 59 years. The control group was made up of 20 healthy persons. The HHC patients over 35 years of age (49.5 years on the average) manifested enlargement of the left ventricular cavity, an increase of the thickness of the interventricular septum and of the posterior heart wall, and reduction of pump function of the left ventricle.
