The correlation existing between the automated external defibrillators (AEDs) and survival after in-hospital cardiac arrest is analyzed. The application of AEDs is not shown to enhance the survival of such patients.

Ko, Brahmajee K. Nallamothu Abstract: Carotid intima-media thickness (CIMT) is increasingly being used as a surrogate end point in randomized control trials (RCTs) of novel cardiovascular therapies. However, it remains unclear whether changes in CIMT that result from these therapies correlate with nonfatal myocardial infarction (MI).

A study was conducted to investigate the association between a lack of health insurance and financial constraints on accessing care among those with health insurance and the time taken from onset to hospital admission in acute myocardial infarction (AMI). Results indicated that such factors did contribute to delays in seeking emergency care for AMI.

The study attempts to estimate racial differences in survival for patients following in-hospital cardiac arrests and the factors associated with it. The results indicate that African-American patients were less likely to survive discharge as compared to white patients and also that most of the racial differences were associated with the hospital in which African-American patients received care.

A study was conducted to evaluate the rates of hospital-wide codes and mortality before implementation by a rapid response team intervention and after. Results indicated that rapid response team intervention did not impact hospital-wide code rates or mortality.

A study to examine how there is a delay in defibrillation given to patients in hospitals in the U.S. after cardiac arrest, which is ultimately responsible for their death, is conducted. Results conclude that delays in defibrillation after cardiac arrest are common and are associated with lower rate of survival.

Chan (a)(b), Cheryl Bartone (c), Terri Booth (c), Dean Kereiakes (c), Theodore Chow (c) Abstract: Prior studies involving microvolt T-wave alternans (MTWA) have combined positive and indeterminate studies into a high-risk 'nonnegative' category. However, studies examining the prognostic utility of specific reasons for an indeterminate study are limited. The objective of this study was to assess if patients have differences in survival prognosis based on the reasons for an indeterminate MTWA result.
