To determine if left ventricular hypertrophy (LVH) influences the prognostic utility of dobutamine cardiovascular magnetic resonance (DCMR) stress test results.
Although LVH is associated with adverse cardiovascular outcomes and occurs in 10% to 25% of patients referred for clinical DCMR stress testing, the influence of LVH on the prognostic utility of DCMR wall motion stress test results is unknown.
Three hundred sixty-two (362) participants, aged 64 ± 12 years (55% men) underwent DCMR for determination of inducible ischemia, and then were followed for 6 ± 2 (range 0.5 to 11.5) years to assess the post-DCMR occurrence of MI or cardiac death assessed by researchers blinded to the results of DCMR. Using previously established criteria, LVH was defined as > 96 g/m2 in men and > 77 g/m2 in women.
LVH forecasts future MI and cardiac death in patients with chest pain referred for dobutamine cardiac stress testing. LVH should be measured and reported in non-invasive cardiac stress tests, particularly those without inducible ischemia, in which otherwise one would assume a favorable cardiac prognosis.
