Do Vertebral Fractures Predict Cardiovascular Events?

QUESTION: can the presence of vertebral fractures on chest CT help predict cardiovascular events?

METHODS: case-cohort design looking at 5,679 patients undergoing chest CT. Follow-up was for a median duration of 4.4 years. Cases were defined as patients who subsequently developed a cardiovascular event (n = 493).

RESULTS: Cases were more likely to be older males. Prevalent vertebral fractures increased the risk of a cardiovascular event by about 30%.

CONCLUSION: Prevalent vertebral fractures on routine clinical chest CT are related to future cardiovascular events but do not have additional prognostic value to models that already include age, gender and cardiovascular calcifications.

COMMENT: routine chest CT scans do not provide a coronary artery calcium score. This study may help risk stratify patients when the CAC isn't available.

Screening for AAA During TTE

Effectiveness of screening for abdominal aortic aneurysm during echocardiography.
This study found that screening for abdominal aortic aneurysm (AP diameter > 30 mm) during transthoracic echocardiography took very little time, but that it should be limited to men ≥65 years and women≥75 years.

Reliability of Carotid MRI

QUESTION: are carotid MRI's reproducible from imaging center to imaging center?

METHODS: A standardized protocol was implemented at 16 imaging sites and multiple quantitative measurements obtained.

RESULTS: Good to excellent reproducibility was observed.

IMPLICATION:  serial MRIs performed at different imaging centers appear to be reliable in monitoring the progression of carotid atherosclerotic plaques.
