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...

Takotsubo cardiomyopathy corresponds to a syndrome characterized by a transient myocardial dysfunction affecting the left ventricular apex that classically occurs after major physical or emotional stress (also called “broken heart syndrome” or “stress-induced cardiomyopathy”). The author describes the case of a patient with takotsubo cardiomyopathy induced by subarachnoid hemorrhage.

The safety and utility of dobutamine stress testing are well established in the evaluation of patients with known or suspected coronary artery disease [1]. Overall incidence of adverse effects during dobutamine stress testing is about 5–10%. Transient regional wall motion abnormalities of left ventricle and hemodynamic effects of dobutamine infusion during stress testing have been described. Ho...

Abiotic stress conditions can be imposed on plants through either poor water quality or adverse climate condition. These types of stress affect plant growth and development throughout their life cycle. Plants that are tolerant to drought are therefore valuable, and turf grasses have the potential to grow tolerant. Turf grasses provide ground cover and offer multiple benefits, from their aesthet...

  Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. Methods: 297 consecutive patients were studie...
