Impact of diabetes mellitus on ischemic cardiomyopathy. Five-year follow-up. REVISION-DM trial.

Diabetol Metab Syndr; 10: 19, 2018.
Artigo em Inglês | MEDLINE | ID: mdl-29568331


Patients with ischemic cardiomyopathy and severe left ventricular dysfunction have a worse survival prognosis than patients with preserved ventricular function. The role of diabetes in the long-term prognosis of this patient group is unknown. This study investigated whether the presence of diabetes has a long-term impact on left ventricular function.


Patients with coronary artery disease who underwent coronary artery bypass graft surgery, percutaneous coronary intervention, or medical therapy alone were included. All patients had multivessel disease and left ventricular ejection fraction measurements. Overall mortality, nonfatal myocardial infarction, stroke, and additional interventions were investigated.


From January 2009 to January 2010, 918 consecutive patients were selected and followed until May 2015. They were separated into 4 groups: G1, 266 patients with diabetes and ventricular dysfunction; G2, 213 patients with diabetes without ventricular dysfunction; G3, 213 patients without diabetes and ventricular dysfunction; and G4, 226 patients without diabetes but with ventricular dysfunction. Groups 1, 2, 3, and 4, respectively, had a mortality rate of 21.6, 6.1, 4.2, and 10.6% ( < .001); nonfatal myocardial infarction of 5.3, .5, 7.0, and 2.6% ( < .001); stroke of .40, .45, .90, and .90% ( = NS); and additional intervention of 3.8, 11.7, 10.3, and 2.6% ( < .001).


In this sample, regardless of the treatment previously received patients with or without diabetes and preserved ventricular function experienced similar outcomes. However, patients with ventricular dysfunction had a worse prognosis compared with those with normal ventricular function; patients with diabetes had greater mortality than patients without diabetes.http: // Number: ISRCTN66068876.
