• #3 Cardiomyopathy – What Is Cardiomyopathy? | NHLBI, NIH

  https://www.nhlbi.nih.gov/health/cardiomyopathy

  Cardiomyopathy is a disease that weakens the heart muscle. This makes it harder for your heart to pump blood. […] Depending on the type of cardiomyopathy that you have, your heart muscle may become thicker, stiffer, or larger than normal. These changes weaken the heart and may cause an irregular heartbeat, heart failure, or a life-threatening event such as cardiac arrest or cardiogenic shock. […] People with cardiomyopathy may have shortness of breath, fatigue, dizziness and fainting, swelling in the ankles or legs, or chest pain as the disease gets worse. […] Some people have no cardiomyopathy symptoms and may not need treatment. Even so, some providers may recommend treatment to prevent progression of the disease. […] Treatments may not fix the problem with your heart, but they may lower symptoms, prevent the disease from getting worse, and reduce the chance of sudden death.

• #4 Symptoms of Cardiomyopathy | Cardiomyopathy UK

  https://www.cardiomyopathy.org/symptoms

  Cardiomyopathy can cause the following symptoms: […] Breathlessness: fluid builds up on the lungs, making it harder to breathe. […] Tiredness: if the heart’s function is reduced, less energy is delivered to the tissues, which can cause fatigue or tiredness. […] Swollen ankles and/or tummy: if the heart can’t pump effectively, fluid can build up in the tissues. This causes swelling (also known as oedema). […] Palpitations: (feeling your heart beating) can be caused by abnormal heart rhythms. These are known as arrhythmias. […] Dizziness or fainting: when your heart isn’t working effectively, your oxygen levels are reduced, causing light-headedness, dizziness and, in some cases, fainting. […] Chest pain: chest pain can be caused by reduced blood flow from the heart. […] Someone with cardiomyopathy may not have all of the symptoms listed here, as the symptoms can vary for each person.

  Symptoms vary from none to feeling tired, leg swelling, and shortness of breath. […] It may also result in chest pain or fainting. […] Complications can include heart failure, heart valve disease, or an irregular heartbeat. […] Dilated cardiomyopathy develops insidiously, and may not initially cause symptoms significant enough to impact on quality of life. Nevertheless, many people experience significant symptoms. These might include shortness of breath, syncope (fainting), and angina, but only in the presence of ischemic heart disease. […] As DCM progresses, two compensatory mechanisms are activated in response to impaired myocyte contractility and reduced stroke volume. […] These responses initially compensate for decreased cardiac output and maintain those with DCM as asymptomatic. Eventually, however, these mechanisms become detrimental, intravascular volume becomes too great, and progressive dilatation leads to heart failure symptoms.

• #16 Dilated cardiomyopathy – Wikipedia

  https://en.wikipedia.org/wiki/Dilated_cardiomyopathy

  The progression of heart failure is associated with left ventricular remodeling, which manifests as gradual increases in left ventricular end-diastolic and end-systolic volumes, wall thinning, and a change in chamber geometry to a more spherical, less elongated shape. This process is usually associated with a continuous decline in ejection fraction.

• #22 Cardiomyopathy

  https://www.healthywa.wa.gov.au/Articles/A_E/Cardiomyopathy

  HCM occurs if the heart muscle cells enlarge and cause the walls of the heart to thicken. This thickening may block blood flow out of the ventricle. If a blockage occurs, the heart must work harder to pump blood to the body. This can cause: chest pain, dizziness, shortness of breath, fainting. […] With this type of cardiomyopathy, the heart becomes stiff and rigid because abnormal tissue, such as scar tissue, replaces the normal heart muscle. As a result, the heart cant pump properly and blood flow to the heart is reduced. This leads to problems such a heart failure or arrhythmias.

  https://www.cincinnatichildrens.org/health/c/cardiomyopathy

  The exact number of patients with hypertrophic cardiomyopathy is unknown, as some patients have no symptoms. The chance of premature death is estimated to be less than 1 percent. Risk factors for sudden death include episodes of passing out, diagnosis at a young age, family history of sudden death, marked heart thickening on echocardiogram, and fast heart rhythms seen on monitoring. In less than 5 percent of patients, late complications can include enlargement of the left ventricle and decreased pumping function. […] As restrictive cardiomyopathy accounts for only five percent of patients with cardiomyopathy, the total number of patients with this disease is small and the overall outcome data is limited. Unfortunately, the available information indicates that prognosis is poor. Only 45 percent to 50 percent of patients with this type of cardiomyopathy are estimated to survive two years after the diagnosis. These patients are typically referred early to heart transplant, before they get other symptoms from their heart disease.

• #27 Hypertrophic Cardiomyopathy Symptoms: Signs to Look For

  https://www.healthline.com/health/heart/signs-of-hypertrophic-cardiomyopathy

  HCM symptoms can be divided into the following four stages: Stage I: This is usually when the disease is not yet showing any noticeable symptoms, though some early signs may appear. Stage II: In this stage, there is a noticeable thickening of the heart muscle, which shows excessive contraction but no significant scarring. The symptoms are usually caused by blockage of the lower part of the left ventricle from displacement of the mitral valve. You might begin to experience things like problems with your heart rate and swelling. Stage III: In this stage, you would develop signs of left-ventricular fibrosis or scarring, negatively affecting your hearts ability to pump blood. Symptoms can include shortness of breath, irregular heartbeat, and nausea. Stage IV: By this stage, you develop overt signs of left ventricular systolic dysfunction (LVSD). Symptoms include difficulty breathing, especially at night, swelling, weight gain, and chest pain.

• #28 What Is Cardiomyopathy? | American Heart Association

  https://www.heart.org/en/health-topics/cardiomyopathy/what-is-cardiomyopathy-in-adults

  Cardiomyopathy is a disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body. […] As cardiomyopathy worsens, the heart becomes weaker. The heart becomes less able to pump blood throughout the body and incapable of maintaining a normal electrical rhythm. The result can be heart failure or irregular heartbeats called arrhythmias. A weakened heart also can cause other complications, such as heart valve problems. […] Some cases of cardiomyopathy have no signs or symptoms and need no treatment. In other cases, cardiomyopathy develops quickly with severe symptoms, and serious complications occur. Treatment is required in these instances. […] Treatments include lifestyle changes, medications, surgery, implanted devices to correct arrhythmias and other nonsurgical procedures. These treatments can control symptoms, reduce complications and prevent the disease from worsening.

• #29 Cardiomyopathy | Stanford Health Care

  https://stanfordhealthcare.org/medical-conditions/blood-heart-circulation/cardiomyopathy.html

  Different types of cardiomyopathies affect the heart in different ways. Depending on the type, the condition may cause your heart muscle to weaken, enlarge, thicken, or stiffen. […] If the disease worsens, it can become more difficult for the heart to pump blood, sometimes leading to a condition known as heart failure, which means that the weakening or stiffness has started to cause other symptoms such as water retention. […] Additionally, a heart with cardiomyopathy can have a harder time beating normally, which can result in abnormal heart rhythms called arrhythmias. Arrhythmias may not necessarily lead to noticeable symptoms but can still increase the risk for sudden cardiac death, stroke, and other complications. Other complications of cardiomyopathy may include heart valve problems and pulmonary hypertension.
