Aspirin and other heart drugs also appear to help in the treatment of this disease, even in extreme cases. After the patient has been diagnosed, and myocardial infarction (heart attack) ruled out, the aspirin regimen may be discontinued, and treatment becomes that of supporting the patient. There is currently no internationally agreed protocol for treatment of this condition.While medical treatments are important to address the acute symptoms of takotsubo cardiomyopathy, further treatment includes lifestyle changes. It is important that the individual stay physically healthy while learning and maintaining methods to manage stress, and to cope with future difficult situations.Although the symptoms of takotsubo cardiomyopathy usually go away on their own and the condition completely resolves itself within a few weeks, some serious short and long-term complications can happen that must be treated. These most commonly include congestive heart failure and very low blood pressure, and less commonly include blood clotting in the apex of the left ventricle, irregular heart beat, and tearing of the heart wall. Heart failure
For patients in acute heart failure, ACE inhibitors, angiotensin receptor blockers, and beta blockers, are considered mainstays of heart failure treatment. But use of beta blockers specifically for takotsubo cardiomyopathy is controversial, because they may confer no benefit. Low blood pressure
For people with cardiogenic shock, medical treatment is based on whether a left ventricular outflow tract (LVOT) obstruction is present. Therefore, early echocardiography is necessary to determine proper management.
