Long-Term Survival Unaffected By Left Coronary Artery Disease
Ten-year mortality risk 2 to 3 percent for patients with or without left coronary artery disease
TUESDAY, Dec. 26 (HealthDay News) -- The long-term survival rate of patients sustaining a right ventricular myocardial infarction are similar in those with and without concomitant left coronary artery disease, according to a report in the Dec. 15 issue of the American Journal of Cardiology.
Joseph Murphy, M.D., and colleagues from the Mayo Clinic in Rochester, Minn., retrospectively identified 69 patients with right ventricular myocardial infarction (RVMI) to determine long-term survival in this group and the additive effects of left coronary artery disease.
Patients with RVMI linked to right coronary artery disease were found to have an actuarial 10-year survival of 62 percent compared with 52 percent for those with both right and left coronary artery disease. Short-term mortality from all RVMI was high overall, but was highest with combined right and left coronary artery disease.
In all, the investigators found an annual actuarial mortality risk from one to 10 years to be 2 percent per year for right coronary artery disease and 3 percent per year for combined right and left coronary artery disease.
"RVMI is associated with substantial first-year mortality, which decreases to a much lower attrition rate between years one and 10, with no greater long-term mortality in those patients with concomitant left coronary artery disease," the authors conclude.
