The application of these therapies could range from the repair
of heart muscle damaged by heart attack to the repair of sports - related bone, cartilage and muscle injuries.
The patient is given an injection of a radioactive substance, which gets absorbed in those
parts of the heart muscle that have normal blood flow.
The molecular
structure of the heart muscle changes as heart failure progresses, though scientists can not always agree on what changes are good or bad.
A heart attack happens if the flow of oxygen - rich blood to a
section of heart muscle suddenly becomes blocked and the heart can't get oxygen.
Unlike your other muscles, however, you can't strengthen and improve the
size of your heart muscle by lifting weights, but what you can do is strengthen its via cardiovascular exercise.
Previous reports have established that a significant percentage of sports competitors show
signs of heart muscle injury and cardiac abnormalities after prolonged exercise.
Current drugs work at the
surface of heart muscle cells to block stress hormones, such as adrenaline, that are produced when the heart is injured.
It was found that both hypothyroidism and diabetes quickly cause harmful changes in the lipid
metabolism of the heart muscle and liver and noticeably reduces the glycogen reserve in the liver.
The effects of the heartworm are to physically block the normal blood flow through your heart and to damage the
lining of the heart muscle inside the right chamber.
For example, dogs with heart disease typically have heart failure from leaky heart valves, while cats with heart disease commonly have
abnormalities of their heart muscles, not their valves.
More specifically, cardiomyopathy, or CM, is a
disease of the heart muscle in which either the heart walls thicken (hypertrophic and restrictive forms) or stretch (dilated form).
The researchers say their findings also shed new light on how kidney disease leads to an abnormal
thickening of heart muscle tissue called hypertrophy, which is a leading cause of death in people with kidney disease caused by high blood pressure, diabetes, and other illnesses.
For example, some cancer treatments, such as HER - 2 targeted therapies, can cause
weakening of the heart muscle, a condition known as heart failure.
Feline hypertrophic cardiomyopathy (HCM) is a disease
of the heart muscle in which the walls thicken and the heart enlarges.
ABC7 / Fox 22 interviews MDI Biological Laboratory scientist Voot P. Yin, Ph.D., about MSI - 1436, a drug candidate that has been shown to stimulate the regeneration
of heart muscle tissue in zebrafish and mice.
Yin's research has identified the role of a microRNA, miR - 101a, a central genetic regulator, in stimulating both the
growth of heart muscle cells and in removing scar tissue.
In 2013, he cofounded a spinoff company, Novo Biosciences, and patented a new drug candidate that activates the
regeneration of heart muscle damaged by a heart attack.
For example, myosin mutations are believed to be behind an inherited disease that causes the
walls of the heart muscle to become too thick or too thin.
Insufficient magnesium can thus contribute to high blood pressure, muscle spasms (including
spasms of the heart muscle or the spasms of the airways symptomatic of asthma), and migraine headaches, as well as muscle cramps, tension, soreness and fatigue.
NSTEMI (non-ST segment elevation myocardial infarction) is the less severe type, occurring when a blood clot partly clogs a coronary artery and only a portion
of the heart muscle supplied by that artery is damaged.
Depending on the location and amount
of heart muscle affected, a blockage can seriously interfere with the heart's ability to pump blood.
But the defective genes that affect the
force of heart muscle contraction in the left ventricle are the same genes that affect the right ventricle.
There are many other things that can cause VPCs in dogs including inflammation
of the heart muscle from certain viruses (parvovirus, etc) other parasites (Chagas), tumors, including tumors in other body organs.
Pros: «Hazelnuts are a good source of the antioxidant vitamin E, which promotes healthy hair and skin, as well as boosting the
health of the heart muscles,» Angelone says.
Drugs commonly used are diuretics (e.g. furosemide to remove fluid that has accumulated in the abdomen or lungs and can cause your dog to drink more water and urinate more), angiotensin - converting enzyme inhibitors (ACE inhibitors to relax blood vessels to allow more efficient blood flow from the heart and to ease the workload on the heart) and positive inotropic agents (e.g. pimobendan to increase the strength of
contractility of the heart muscle tissue).
Dilated cardiomyopathy (DCM) Cardiomyopathy usually affects dogs under seven years old, and involves dilation or enlargement of the bottom of the heart and
thinning of the heart muscle, leading to congestive heart failure.
«Scientists find what might be responsible for slow heart function under general anesthesia: New research in The FASEB Journal suggests that general anesthesia targets certain amino acids on
proteins of the heart muscle fibers and cells which directly affects the ability of the heart to pump.»
