Factors That Impact the Decision to Perform Left Ventriculography in Coronary Artery Disease.

Background: Left ventriculography is an invasive method for assessment of left ventricular systolic function. Since the advent of noninvasive methods, its use has been questioned, as it carries some risk to the patient.

Objective: To assess which factors are independently associated with the decision to perform ventriculography in patients with coronary artery disease.

Methods: Analytical, retrospective, database review study of electronic medical records comparing 21 predefined variables of interest among patients undergoing coronary angiography. P-values <0.05 were considered significant.

Results: We evaluated 600 consecutive patients undergoing coronary angiography. Left ventriculography was performed in the majority of cases (54%). After multivariate analysis, patients with chronic coronary syndrome (OR 1.72; 95% CI: 1.20-2.46; p < 0.01) were more likely to undergo the procedure. Patients with known ventricular function (OR 0.58; 95% CI: 0.40-0.85; p < 0.01); those with a history of CABG (OR 0.31; 95% CI: 0.14-0.69; p < 0.01) or hypertension (OR 0.58; 95% CI: 0.36-0.94; p = 0.02); and those with higher creatinine levels (OR 0.42; 95% CI: 0.26-0.69; p < 0.01) had greater odds of not undergoing ventriculography.

Conclusions: In patients undergoing coronary angiography, a diagnosis of chronic coronary syndrome was independently associated with greater likelihood of left ventriculography, while having previously determined ventricular function, a history of hypertension or CABG, and higher creatinine levels were associated with a decreased likelihood of undergoing this procedure.
