Abstract
Background: Since the 1970s, only a few studies have evaluated the accuracy of noninvasive screening exercise tests for detecting coronary artery disease (CAD) in symptomatic individuals with mitral valve prolapse (MVP). The present systematic review has been designed to summarize the main findings of these studies and to assess the overall pooled estimates of sensivity and specificity of exercise ECG, exercise myocardial perfusion scintigraphy (MPS) and exercise stress echocardiography (ESE) in diagnosing CAD among MVP individuals.
Methods: All studies examining the specificity and sensitivity of exercise ECG and/or exercise MPS and/or ESE in detecting obstructive CAD in symptomatic MVP patients, selected from PubMed and EMBASE databases, were included. There was no limitation of time period. The risk of bias was assessed by using the National Institutes of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.
Results: The full texts of 11 studies with 840 MVP individuals were analyzed. True obstructive CAD was documented in 11.1% of MVP individuals (range 0-31.2%). When used in MVP patients with suspected CAD, exercise ECG, exercise MPS and ESE showed a pooled specificity of 61.9% (range 25-91.7%), 82.3% (range 25-100%) and 89% (range 80.5-97.6%), respectively, and a pooled sensitivity of 80% (range 50-100%), 96.7% (range 90-100%) and 91% (range 82-100%), respectively. The pooled positive predictive value was 33.2% (range 23.1-44.8%) for exercise ECG, 100% for exercise MPS and 80.2% (range 75.8-84.6%) for ESE, whereas the pooled negative predictive value was 80% (range 50-100%) for exercise ECG, 97% for exercise MPS and 99% (range 97.6-100%) for ESE.
Conclusion: ESE appears to be the first-choice screening method for CAD detection in symptomatic MVP individuals. It allows true CAD in symptomatic MVP individuals with false-positive exercise ECG results to be ruled out, without ionizing radiation exposure.
期刊介绍：
Journal of Cardiovascular Medicine is a monthly publication of the Italian Federation of Cardiology. It publishes original research articles, epidemiological studies, new methodological clinical approaches, case reports, design and goals of clinical trials, review articles, points of view, editorials and Images in cardiovascular medicine.
Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
