Cardiovascular risk assessment: Missing albuminuria contributing to gender inequality.

INTRODUCTION

Chronic kidney disease (CKD) is associated with high cardiovascular disease (CVD) risk, and requires specific interventions to decreases CVD risk. The guidelines indicate that systematic global CVD risk assessment is recommended in individuals with any major vascular risk factor. The European Society Cardiology (ESC) guidelines, he European Renal Association (ERA) Council and the Spanish Society of Nephrology (S.E.N.) in collaboration with 15 Scientific Societies recommend assessing albuminuria in all these populations. We have evaluated current clinical practice regarding the assessment of CVD risk factors (blood pressure, albuminuria, serum cholesterol, glycemia and creatinine) in different adult health user populations, analyzing the results separately for men and women, given recent evidence on gender differences in the recognition, monitoring, and management of CKD.

METHODS

Observational, retrospective, non-interventional single center study performed in a hospital using Electronic Health Record (EHR) data.

RESULTS

Among 707,493 healthcare users, 612,619 were adults, and of these 332,943 (54.3%) females; 73,632 (12.0%) had DM and 121,445 (19.8%) hypertension. Mean (SD) age was 68.91±21.4 years; 261,694 (36.9%) were older than 50 years. Only 8522 (1.39%) had undergone albuminuria testing as compared with 264,684 (43.21%) tested for serum creatinine, 140,492 (22.93%) for serum cholesterol, 263,381 (42.99%) for serum glucose, and 226,448 (36.96%) for blood pressure. Albuminuria was the only cardiovascular risk factor assessed more frequently in men than in women. Albuminuria, as other CVD risk factors, was more frequently assessed in patients with DM (6.71% of patients) or hypertension (4.81%), but albuminuria assessment remained suboptimal compared with 58-87% for other cardiovascular risk factors. For adults with diabetes or hypertension, albuminuria was assessed more frequently in men than in women. Albuminuria assessment in those older than 50 years was also suboptimal at 2.24%, as compared with 31-47% for other CVD risk factors. Albuminuria and EGFR are needed to screen for CKD, meaning that a urine test for albumin and creatinine and a serum test for creatinine are needed. To these, we may add assessment of blood pressure, serum cholesterol (for familial hypercholesterolemia) and serum glucose for Diabetes. Albuminuria was the only cardiovascular risk factor that was assessed more frequently in men (up to nearly 60% more frequently), indicating that screening for CKD and CVD risk in women is suboptimal. This result is surprisingly consistent across time and in all age groups. This is the first time that gender disparities in the assessment of albuminuria have been revealed.

CONCLUSION

Albuminuria is assessed infrequently, even in patients with a high cardiovascular risk, especially in women.
