2. Cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Cardiomyopathy

   Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1] An irregular heart beat and fainting may occur. [1]

3. Aerobic conditioning - Wikipedia

   en.wikipedia.org/wiki/Aerobic_conditioning

   Some neuromuscular diseases recommend regular aerobic exercise (of varying intensities depending on the disease) in order for the skeletal muscles to become aerobically conditioned, providing symptom relief or slowing the course of the disease, for example metabolic myopathies, Duchenne muscular dystrophy, and idiopathic inflammatory myopathies ...

4. Left ventricular hypertrophy - Wikipedia

   Disease processes that can cause LVH include any disease that increases the afterload that the heart has to contract against, and some primary diseases of the muscle of the heart. [ citation needed ] Causes of increased afterload that can cause LVH include aortic stenosis , aortic insufficiency and hypertension .

   People with TIC most often present with symptoms of congestive heart failure and/or symptoms related to their irregular heart rhythm. [1] Symptoms of congestive heart failure can include shortness of breath, ankle swelling, fatigue, and weight gain. [2] Symptoms of an irregular heart rhythm can include palpitations and chest discomfort. [2]

6. Cardiovascular fitness - Wikipedia

   en.wikipedia.org/wiki/Cardiovascular_fitness

   Cardiovascular fitness is a component of physical fitness, which refers to a person's ability to deliver oxygen to the working muscles, including the heart.Cardiovascular fitness is improved by sustained physical activity (see also Endurance Training) and is affected by many physiological parameters, including cardiac output (determined by heart rate multiplied by stroke volume), vascular ...

7. Pathophysiology of heart failure - Wikipedia

   en.wikipedia.org/wiki/Pathophysiology_of_heart...

   The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and cardiac amyloidosis (in which misfolded ...
