Popis: | Preoperative screening for coronary artery disease is recommended in high-risk renal transplant candidates. Aim of this study was to prospectively assess the value of a comprehensive risk stratification strategy including clinical, resting echo, and dipyridamole stress echo findings before renal transplantation.The study group consisted of 71 renal transplant candidates (47 men; age 54+/-11 years) fulfilling one or more of the following high-risk clinical criteria: history of coronary artery disease, wall motion abnormalities at resting echo, dialysis dependency lasting5 years, presence of 2 or more risk factors. Clinical history, resting echo, and dipyridamole stress echo (up to 0.84 mg over 10 min + atropine up to 1 mg) were obtained in all subjects.Mean number of risk factors was 2.5+/-1.0. Known coronary artery disease and diabetes were present, respectively, in 2 (3%) and 11 (15%) persons. No patient had left ventricular ejection fraction45%. Left ventricular hypertrophy was found in 53 (74%) cases. Stress echo showed 100% safety and 97% overall feasibility. Inducible ischemia (new wall motion abnormalities) was detected in 3 (4%) subjects. During follow-up (36+/-12 months), 8 (11%) cardiac events occurred: 2 deaths, 2 myocardial infarctions, 3 coronary interventions, and 1 pulmonary edema. The perioperative period and subsequent follow-up (22+/-12 months) was uneventful among 32 patients who received renal transplantation. Four-year event-free survival was 92% in those without ischemia; it was 96% in the non-diabetic population. Diabetes (HR=4.78), age (HR=1.14), and left ventricular mass index (HR=1.02) were independent prognostic indicators among clinical and resting echo variables. The global chi-square of the statistical model was 18.8; it increased to 27.3 (+45%) after the addition of stress echo result.Renal transplant candidates can undergo effective stratification of risk by combining clinical, resting echo and dipyridamole stress echo findings. |
