Cardiomyopathy is a disease of the heart muscle that makes it harder for your heart to pump blood to the rest of your body, potentially leading to heart failure. There are several types of cardiomyopathy, including dilated, hypertrophic, and restrictive cardiomyopathies. Disease severity and progression can greatly vary from person to person, necessitating individualized treatment plans tailored to each patient's unique circumstances.
In Dilated Cardiomyopathy, the disease most commonly diagnosed, the heart's main pumping chamber - the left ventricle - becomes enlarged (dilated) and can't effectively pump blood out of the heart. Although both men and women are affected, men are more often diagnosed.
Hypertrophic Cardiomyopathy involves abnormal growth or thickening of the heart muscle, most commonly at the septum. This thickening can block blood flow out of the heart, forcing the heart to work harder to pump blood. It's often inherited, and the condition usually affects men and women equally.
Restrictive Cardiomyopathy, the least common type, primarily affects older adults. It features the hardening or scarring of the heart muscle that makes it harder for the lower chambers to stretch and fill with blood. Its root cause is often difficult to determine and it tends to affect older people more.
The symptoms of cardiomyopathy can range from none at all to severe. They include fatigue, breathlessness with exertion or even at rest, swelling in the legs, ankles and feet, bloating caused by fluid buildup in the abdomen, and more severe symptoms such as fainting, chest pain or pressure, and sudden, life-threatening irregular heartbeats. The symptom severity often correlates with the disease's progression, but sudden serious complications, like stroke, can occur.
Treatment options depend on the type of cardiomyopathy and severity of symptoms and can include medications, surgically implanted devices or, in severe cases, a heart transplant.
Unfortunately, the causes of cardiomyopathy are often idiopathic, meaning they're unknown. Genetic factors can play a significant role, especially in hypertrophic cardiomyopathy. Long-standing uncontrolled high blood pressure, rapid heart rate, metabolic disorders, and nutrient deficiency can also contribute to the disease.
Research is ongoing to find improved ways of diagnosing, treating, and preventing cardiomyopathy and its complications. Although there isn't yet a cure, certain lifestyle modifications can help manage symptoms and improve quality of life. These include eating a healthy diet, reducing salt intake, regular exercise, avoiding the use of tobacco and alcohol, managing stress, and getting enough sleep.
Given that cardiomyopathy can also go unnoticed until it is seemingly too late, regular screening for high-risk individuals is crucial. Despite the potential severity of cardiomyopathy, early diagnosis and appropriate management can significantly enhance patients' outlook, enhancing their capacity to lead active and productive lives.
