Cardiac difficulties in FA

Heart failure is a leading cause of death in F A. Cardiac abnormalities occur in about 75 percent of people with F A, but they vary widely in severity. Some people with F A have abnormalities so mild that they’re noticeable only through specialized laboratory testing, while others may have life-threatening cardiac problems. The cardiac abnormality most often seen in F A is hypertrophic cardiomyopathy, an enlargement of cardiac muscle that shrinks the blood-filled chambers in the heart, decreasing its pumping capacity and leading to heart failure.
