A new study uncovers potential mechanisms that may contribute to “broken heart syndrome,” or Takotsubo syndrome (TTS), a temporary heart condition that is brought on by stressful situations and emotions.

Multi-modality Imaging of Atherosclerotic Plaques
The majority of myocardial infarctions and sudden cardiac death result from the rupture of plaques which, in most cases, did not cause significant flow limitation prior to the acute event. While stenosis severity (measured with techniques such as angiography and stress testing), is the gold standard for characterization of atherosclerotic disease, it has proven a poor predictor of therapeutic efficacy and a coarse predictor of risk. Novel methods for the characterization of plaques are needed. Accordingly, the focus of Dr Tawako? s laboratory is to develop, validate, and apply novel imaging methods to non-invasively characterize atherosclerotic plaques, with a focus on plaque inflammation.
To that end, Dr Tawakol's group has developed and validated methods using positron emission tomography that enables the non-invasive measurement of plaque inflammation in patients. Currently, Dr Tawakol leads several multi-center trials that are evaluating the efficacy of novel drugs for reducing plaque inflammation.
