Abstract
We investigated hemodynamics and clinical features of cardiogenic shock caused by acute myocardial infarction. The cardiogenic shock patients tend to fall into severe con-dition easily, and are difficult to be successfully treated by non-invasive procedures today.
Patients and methods
We studied 10 patients of cardiogenic shock immediately after the onset of acute myo-cardial infarction. Hemodynamics monitoring was studied by means of Swan-Ganz catheter. The effectiveness of dopamine hydrochloride for cardiogenic shock is estimated by hemodynamics and clinical signs.
Results
Ten patients of cardiogenic shock were treated by non-invasive procedures, and 7 patients of them were recovered from critical condition. Hemodynamics of them varied with individual difference. A few of patients needed a large dose of dopamine hydrochloride for a long period, whereas the others required common dose of vasopressive drugs. Several patients had arrhythmias and cardiac failure as well as cardiogenic shock as complications of acute myocardial infarction. Some of them have no choice but to have artificial pace-maker. The cardiac output is the most reliable index of the clinical course and hemodynamics of the cardiogenic shock.
Conclusion
Dopamine hydrochloride, diuretics and nitrates are effective for the cardiogenic shock. It is important to treat arrhythmias and cardiac failure as soon as possible to save the patients from the life threatening state. Taking an accurate measurement of hemodynamics and treatment without delay enable the patients to be recovered before they fall into irre-versible shock. There are cases who relieved with a larger dose of dopamine hydrochloride than the usual dose, 3 cases of the fatal result include the patients who had the dissemi-nated intravascular coagulation, severe adult respiratory distress syndrome and renal failure
