Study shows new imaging tracer clarifies cause of chest pain up to 30 hours after pain stops

Shortness of breath without chest pain can signify the presence of high risk heart disease
.... However, even after adjusting for the amount of ischemia
statistically, shortness of breath remained predictive of an adverse outcome. The authors speculated that possibly inflammatory proteins that are associated with the development of coronary artery disease--proteins that have been associated with mala...

Jefferson researchers find drug may give some cardiac protection 24 hours after heart attack
