BACKGROUND: Cardiovascular disease is the leading cause of morbidity and mortality in uraemia. Coronary angiography (CA) in patients awaiting kidney transplantation (PAKT) is still a matter of debate. In order to evaluate atherosclerotic coronary damage in PAKT, CAs of 12 PAKT were matched with those of 13 dialysis patients (P) affected by ischaemic heart disease IHD. METHODS: Age sex, length of time on renal replacement therapy, diabetes, smoking and hyperphosphataemia history, clinical diagnosis of IHD, cerebrovascular (CV) and peripheral vascular (PV) disease, mean blood pressure (BP), cholesterol, triglycerides, calcium, phosphate, albumin, haemoglobin, haematocrit and weekly dose of erythropoietin (EPO-dose) were derived from clinical records. RESULTS: PAKT were younger (48 9 vs 63 9 years, p < 0.01) and had higher diastolic BP values (86+/-10 vs 79+/-4 mmHg, p < 0.05) than IHD P. On the contrary all the other parameters investigated were not different in the two groups of P. Prevalence of IHD in PAKT was 16% while frequency of CV and VP disease were not different in the two groups. In 9 of IHD P stenotic lesions >/=75% of normal reference segment were diagnosed in 3 or more vessels whilst in PAKT there were atherosclerotic lesions in right coronary artery, left anterior descending artery and left circumflex artery in 41, 66 and 33% respectively. Narrowing percentage of the coronaries in PAKT and IHD P were: right coronary artery 27+/-42 vs 75+/-35, p < 0.05, left anterior descending artery 29+/-25 vs 86+/-15, p < 0.001, left circumflex artery 11 16 vs 47+/-38, p < 0.05 respectively. CONCLUSIONS: Our study shows that atherosclerotic coronary damage is present in PAKT and, although not hemodynamically significant, it could be an important risk factor for clinical expression of IHD. We conclude that CA should be performed in PAKT especially in those over 45 years.

Abstract

BACKGROUND: Cardiovascular disease is the leading cause of morbidity and mortality in uraemia. Coronary angiography (CA) in patients awaiting kidney transplantation (PAKT) is still a matter of debate. In order to evaluate atherosclerotic coronary damage in PAKT, CAs of 12 PAKT were matched with those of 13 dialysis patients (P) affected by ischaemic heart disease IHD. METHODS: Age sex, length of time on renal replacement therapy, diabetes, smoking and hyperphosphataemia history, clinical diagnosis of IHD, cerebrovascular (CV) and peripheral vascular (PV) disease, mean blood pressure (BP), cholesterol, triglycerides, calcium, phosphate, albumin, haemoglobin, haematocrit and weekly dose of erythropoietin (EPO-dose) were derived from clinical records. RESULTS: PAKT were younger (48 9 vs 63 9 years, p < 0.01) and had higher diastolic BP values (86+/-10 vs 79+/-4 mmHg, p < 0.05) than IHD P. On the contrary all the other parameters investigated were not different in the two groups of P. Prevalence of IHD in PAKT was 16% while frequency of CV and VP disease were not different in the two groups. In 9 of IHD P stenotic lesions >/=75% of normal reference segment were diagnosed in 3 or more vessels whilst in PAKT there were atherosclerotic lesions in right coronary artery, left anterior descending artery and left circumflex artery in 41, 66 and 33% respectively. Narrowing percentage of the coronaries in PAKT and IHD P were: right coronary artery 27+/-42 vs 75+/-35, p < 0.05, left anterior descending artery 29+/-25 vs 86+/-15, p < 0.001, left circumflex artery 11 16 vs 47+/-38, p < 0.05 respectively. CONCLUSIONS: Our study shows that atherosclerotic coronary damage is present in PAKT and, although not hemodynamically significant, it could be an important risk factor for clinical expression of IHD. We conclude that CA should be performed in PAKT especially in those over 45 years.
