[Albuminuria and cardiovascular risk: basal results of the KORAL-CARDIO study].
BACKGROUND AND OBJECTIVES: Albuminuria is a marker of higher cardiovascular and renal risk in hypertension; it also indicates the need of a tighter control of blood pressure with drugs blocking the renin-angiotensin system. The objective of the KORAL-CARDIO study was to assess the clinical picture and management of patients with hypertension and cardiac disease and albuminuria not previously treated with angiotensin inhibitors. METHODS: A total of 2711 hypertensive patients (44% female) with ischemic or hypertensive cardiopathy or atrial fibrillation and with a positive screening test for albuminuria was included. Type 2 diabetes was also present in 42%. RESULTS: Macroalbuminuria was present in 7.2% of non diabetic and 12.7% of diabetic patients, respectively. Associated complications were: 25% and 35% body mass index over 30 kg/m2; 22% and 39% ischemic heart disease; 4% and 8% stroke; 19% and 22% atrial fibrillation; 42% and 53% high cholesterol levels; 8% and 8% grade 3 hypertension, for non-diabetics and diabetics respectively. Antihypertensive monotherapy was used in 66% of non-diabetics and in 63% of diabetics; only 7% of patients in both groups were treated with triple antihypertensive therapy. CONCLUSIONS: Cardiovascular complications are very frequently associated to albuminuria in patients with hypertension and heart disease not previously treated with angiotensin inhibitors. Blood pressure control was clearly inadequate in this group.
