The onset of the condition is caused by high levels of catecholamines, particularly adrenaline. This weakens the upper chambers of the heart, but generally has no effect on the lower chambers. This causes the heart to bulge out at the top, giving it the look from which the condition is named. It is difficult to distinguish from a myocardial infarction, except that there is no overall heart damage with this condition and the patient's angiogram will usually show no blockages that could explain the heart failure. An echocardiogram will show that the base of the left ventricle is beating normally or very quickly, while the rest of the ventricle is not beating at all.

abstract
| - The onset of the condition is caused by high levels of catecholamines, particularly adrenaline. This weakens the upper chambers of the heart, but generally has no effect on the lower chambers. This causes the heart to bulge out at the top, giving it the look from which the condition is named. It is difficult to distinguish from a myocardial infarction, except that there is no overall heart damage with this condition and the patient's angiogram will usually show no blockages that could explain the heart failure. An echocardiogram will show that the base of the left ventricle is beating normally or very quickly, while the rest of the ventricle is not beating at all. Once diagnosed, the condition is very treatable and very survivable. The highest risk is during the initial acute stage when the disease may be misdiagnosed. Although patients will often present with low blood pressure due to the inefficient beating of the heart, treating this symptom will actually make the condition worse. Ironically, drugs that lower blood pressure (and also block catecholamines) are far more effective, such as beta blockers and calcium channel blockers. Apart from that, patients should be given fluids and observed carefully. In some cases, the aorta may require expansion.
