If some cardiac (heart) muscle cells are damaged for some reason, cardiac wall thickening will occur to compensate for this disadvantage. In severe cases, swollen walls may weaken the circulation in and out of the heart. The symptoms of this disorder (known as hypertrophic cardiomyopathy) are exhaustion, chest pain, loss of breath and heartburn. If you have any of these symptoms, contact your doctor who will refer you to the diagnostic tests – electrocardiogram (ECG), X-rays, and maybe biopsy (extracting muscle pieces for microscopic examination).
Hypertrophic cardiomyopathy can not be cured, but symptoms may be alleviated by beta-blockers and diuretics. In a small number of people who had a risk of heart failure as a consequence of hypertrophic cardiomyopathy, a heart transplant operation was performed.
