However, it is not fully understood if combining the findings of MPS and Ex\u2010ECG improves risk prediction. Current guidelines no longer recommend Ex\u2010ECG for diagnostic evaluation of chronic coronary syndrome, but Ex\u2010ECG could still be of incremental prognostic importance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      This study comprised 908 consecutive patients (age 63.3\u00b19.4\u2009years, 49% male) who performed MPS with Ex\u2010ECG. Subjects were followed for 5\u2009years. The end point was a composite of cardiovascular death, acute myocardial infarction, unstable angina, and unplanned percutaneous coronary intervention. National registry data and medical charts were used for end point allocation. Combining the findings of MPS and Ex\u2010ECG resulted in concordant evidence of ischemia in 72 patients or absence of ischemia in 634 patients. Discordant results were found in 202 patients (MPS\u2212\/Ex\u2010ECG+, n=126 and MPS+\/Ex\u2010ECG\u2212, n=76). During follow\u2010up, 95 events occurred. Annualized event rates significantly increased across groups (MPS\u2212\/Ex\u2010ECG\u2212 =1.3%, MPS\u2212\/Ex\u2010ECG+ =3.0%, MPS+\/Ex\u2010ECG\u2212 =5.1% and MPS+\/Ex\u2010ECG+ =8.0%). In multivariable analyses MPS was the strongest predictor regardless of Ex\u2010ECG findings (MPS+\/Ex\u2010ECG\u2212, hazard ratio [HR], 3.0,\n                      <jats:italic>P<\/jats:italic>\n                      =0.001 or MPS+\/Ex\u2010ECG+, HR,4.0,\n                      <jats:italic>P<\/jats:italic>\n                      &lt;0.001). However, an abnormal Ex\u2010ECG almost doubled the risk in subjects with normal MPS (MPS\u2212\/Ex\u2010ECG+, HR, 1.9,\n                      <jats:italic>P<\/jats:italic>\n                      =0.04).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">In patients with chronic coronary syndrome, combining the results from MPS and Ex\u2010ECG led to improved risk prediction. Even though MPS is the stronger predictor, there is an incremental value of adding data from Ex\u2010ECG to MPS, especially in patients with normal MPS.<\/jats:p>\n
