Hibernating myocardium may cause chest pain or shortness of breath in some people. But often there are no symptoms. Only a cardiologist or heart failure specialist can assess whether your heart muscle is dormant by using one of these imaging techniques:.
Ask your cardiologist if one of these tests is right for you prior to any cardiac bypass surgery or stent placement to revive your heart muscle, Dr. Jaber advises, especially if you do not have symptoms of chest pain or chest discomfort. Can your cardiologist revive it and strengthen your heart? Learn more about vaccine availability. Learn more about how heart attacks occur by watching this animation.
What should I do if I think I'm having a heart attack? If you think you are having a heart attack, the first thing you must do is dial This is also known as an uncomplicated heart attack. Other people experience a major heart attack, which has a wide range of potential complications and may require extensive treatment. Arrhythmias can develop after a heart attack as a result of damage to the heart muscles.
Damaged muscles disrupt electrical signals that control the heart. These life-threatening types of arrhythmia can be a major cause of death during the 24 to 48 hours after a heart attack. However, survival rates have improved significantly since the invention of the portable defibrillator — an external device that delivers an electric shock to the heart and "resets" it to the right rhythm.
Mild arrhythmias can usually be controlled with medicine such as beta-blockers. More troublesome bradycardias that cause repeated and prolonged symptoms may need to be treated with a pacemaker. This is an electric device surgically implanted in the chest to help regulate the heartbeat. It kicks in when needed and turns off when the heart is fully healed.
Kazu Kikuchi. Robert Graham, head of the Cardiac Receptor Biology Laboratory, at the Victor Chang Cardiac Research Institute, comments on the implications of the research, in which he was not involved:. We are now hoping further research into its function may provide us with a clue to turn on regeneration in human hearts [in order] to improve their ability to pump blood around the body.
If future studies show how myocardial plasticity is blocked and reactivated in humans, this may lead to innovative treatments that could potentially reduce or reverse damage due to a heart attack. This discovery has the potential to revolutionize the treatment of heart disease. Here, learn to recognize a heart attack and what to do next. We also describe treatment and recovery and provide tips for prevention. Heart disease is a major cause of death.
