Prolonged left ventricular dysfunction occurs in patients with coronary artery disease after both dobutamine and exercise induced myocardial ischaemia.
OBJECTIVE To determine whether pharmacological stress leads to prolonged but reversible left ventricular dysfunction in patients with coronary artery disease, similar to that seen after exercise. DESIGN A randomised crossover study of recovery time of systolic and diastolic left ventricular function after exercise and dobutamine induced ischaemia. SUBJECTS 10 patients with stable angina, an...
متن کاملSevere transient left ventricular dysfunction induced by thyrotoxicosis
We report on a 44-year-old woman presenting with chest pain and dyspnoea without previous stress-related events. By means of echocardiography severe left ventricular dysfunction and wall motion abnormalities resembling stress-induced cardiomyopathy (Tako Tsubo) were seen. Laboratory investigation revealed thyrotoxicosis and elevated cardiac markers. Six days after starting medical treatment, co...
متن کاملmid-ventricular variant of dobutamine-induced stress cardiomyopathy
conclusions the mechanism of mid-variant of dobutamine-induced stress cardiomyopathy remains unclear. we think that multiple mechanisms are involved and this risk should be considered in patients with comorbid psychiatric conditions and with use of centrally acting stimulants. case presentation we report a 48-year-old female with intermittent chest pain. her physical exam, cardiac enzymes and t...
متن کاملLeft ventricular systolic dysfunction during exercise and dobutamine stress in patients with hypertrophic cardiomyopathy.
OBJECTIVES We sought to characterize stress-induced left ventricular systolic dysfunction in patients with hypertrophic cardiomyopathy (HCM). BACKGROUND Myocardial ischemia and diastolic dysfunction occur in patients with HCM. We hypothesized that, in the setting of transient myocardial ischemia, left ventricular systolic dysfunction occurs during exercise and dobutamine stress. METHODS We ...
متن کاملRevascularization in severe left ventricular dysfunction.
The highest-risk patients with heart failure with reduced ejection fraction are those with ischemic cardiomyopathy and severe left ventricular systolic dysfunction (ejection fraction≤35%). The cornerstone of treatment is guideline-driven medical therapy for all patients and implantable device therapy for appropriately selected patients. Surgical revascularization offers the potential for improv...
