RESUMO
Background: Chronic kidney disease (CKD) is associated with a high burden of coronary artery disease (CAD), which remains the leading cause of death in CKD patients. Despite the high cardiovascular risk, ACS patients with renal dysfunction are less commonly treated with guideline-based medical therapy and are less frequently referred for coronary revascularization. Summary: The management of CAD is more challenging in patients with CKD than in the general population due to concerns regarding side effects and renal toxicity, as well as uncertainty regarding clinical benefit of guideline-based medical therapy and interventions. Patients with advanced CKD and especially those receiving dialysis have not traditionally been represented in randomized trials evaluating either medical or revascularization therapies. Thus, only scant data from small prospective studies or retrospective analyses are available. Recently published studies suggest that there are significant opportunities to substantially improve both cardiovascular and renal outcomes of patients with CAD and CKD, including new medications and interventions. Thus, the objective of this review is to summarize the current evidence regarding the management of CAD in CKD patients, in particular with respect to improvement of both cardiovascular and renal outcomes. Key Messages: Adequate medical therapy and coronary interventions using evidence-based strategies can improve both cardiac and renal outcomes in patients with CAD and CKD.
RESUMO
Frailty has been associated with poor outcomes in patients with cardiovascular diseases (CVDs). We aimed to assess the accuracy of the Eyeball test for frailty assessment in elderly patients with CVD. This is a prospective study including stable patients ≥75 years old who were followed-up in a cardiology clinic. Frailty assessment was performed separately through the Eyeball test and the Fried test in a blinded way. Cardiologists were asked to rate the frailty status of participants based on their routine clinical assessment and grade frailty on a Fried-type scale (1 to 5, with frailty defined as a score ≥3). Each patient then underwent formal frailty assessment using the Fried test. Included were 300 consecutive patients with a mean age of 81 ± 6 years. Frailty was diagnosed in 109 (36%) and 125 patients (41%) according to the Fried and Eyeball tests, respectively. The Eyeball test demonstrated 86% sensitivity and 82% specificity for the diagnosis of frailty. A receiver operating characteristics curve analysis demonstrated an area under the curve of 0.82 for the diagnosis of frailty. The Eyeball test demonstrated a very high negative predictive value of 90% and a modest positive predictive value of 73% for frailty assessment. Similar results were observed after subgroup analysis according to age and gender. In conclusion, the Eyeball test is an accurate method to rule out frailty in elderly patients with CVD. However, when frailty is suspected based on the Eyeball test, a formal tool such as the Fried test should be used to confirm the diagnosis.
