Prevalence of cardiovascular disease is high in diabetic patients on renal replacement therapy (RRT); therefore we examined the role of diabetes mellitus on determining the degree of coronary artery stenosis. Twenty-five patients underwent coronary angiography, 12 were awaiting kidney transplantation and the examination was performed regardless of cardiac symptoms, 13 were affected by ischaemic heart disease (IHD). Diabetic and nondiabetic status together with the other risk factors for cardiovascular disease such as age, sex, length of time on RRT, smoking and elevated phosphorus levels history, clinical diagnosis of IHD, cerebrovascular and peripheral vascular disease, mean blood pressure, cholesterol, triglycerides, calcium, phosphate, albumin, haemoglobin, haematocrit and weekly dose of erythropoietin were derived from clinical records. All investigated parameters were matched in diabetic (group 1, n=10) and nondiabetic patients (group 2, n=15) and showed no differences. Clinical evidence of IHD was detected in 80% of patients in group 1 and 46% in group 2 and the percentage of patients on the renal transplant waiting list was not statistically different in the two groups (30 vs 60%). In 60% of patients in group 1 there were 3 or more stenotic lesions equal or greater than 75% of normal reference segment in the major coronary arteries, whilst in 53% in group 2 there were no haemodynamically significant narrowings. Narrowing percentage of the coronaries in group 1 and 2 were: right coronary artery 83(plus or minus)30 vs 32(plus or minus)41 (p<0.05), left anterior descending artery 80(plus or minus)25 vs 44(plus or minus)34 (p<0.05), left circumflex artery 46(plus or minus)37 vs 18(plus or minus)29 (p=0.05) respectively. Our study confirms that IHD is a clinical feature of uraemic diabetic patients and that diabetes is the main cardiovascular risk factor for determining the degree of coronary stenosis.

Abstract
Prevalence of cardiovascular disease is high in diabetic patients on renal replacement therapy (RRT); therefore we examined the role of diabetes mellitus on determining the degree of coronary artery stenosis. Twenty-five patients underwent coronary angiography, 12 were awaiting kidney transplantation and the examination was performed regardless of cardiac symptoms, 13 were affected by ischaemic heart disease (IHD). Diabetic and nondiabetic status together with the other risk factors for cardiovascular disease such as age, sex, length of time on RRT, smoking and elevated phosphorus levels history, clinical diagnosis of IHD, cerebrovascular and peripheral vascular disease, mean blood pressure, cholesterol, triglycerides, calcium, phosphate, albumin, haemoglobin, haematocrit and weekly dose of erythropoietin were derived from clinical records. All investigated parameters were matched in diabetic (group 1, n=10) and nondiabetic patients (group 2, n=15) and showed no differences. Clinical evidence of IHD was detected in 80% of patients in group 1 and 46% in group 2 and the percentage of patients on the renal transplant waiting list was not statistically different in the two groups (30 vs 60%). In 60% of patients in group 1 there were 3 or more stenotic lesions equal or greater than 75% of normal reference segment in the major coronary arteries, whilst in 53% in group 2 there were no haemodynamically significant narrowings. Narrowing percentage of the coronaries in group 1 and 2 were: right coronary artery 83(plus or minus)30 vs 32(plus or minus)41 (p<0.05), left anterior descending artery 80(plus or minus)25 vs 44(plus or minus)34 (p<0.05), left circumflex artery 46(plus or minus)37 vs 18(plus or minus)29 (p=0.05) respectively. Our study confirms that IHD is a clinical feature of uraemic diabetic patients and that diabetes is the main cardiovascular risk factor for determining the degree of coronary stenosis.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
