Atherosclerotic Renovascular Disease

Atherosclerotic renovascular disease (ARVD) refers to atheromatous narrowing of one or both renal arteries and frequently co-exists with atherosclerotic disease in other vascular beds. Patients with this condition are at high risk of adverse cardiovascular events, with mortality around 8% per year. Many patients with ARVD have chronic kidney disease, but only a minority progress to end-stage kidney disease (ESKD), suggesting that pre-existing hypertensive and/or ischaemic renal parenchymal injury is the usual cause of renal dysfunction. Many patients with ARVD are asymptomatic, but there can be important complications such as uncontrolled hypertension, rapid decline in kidney function and recurrent acute heart failure (flash pulmonary oedema)....

Atherosclerotic Renovascular Disease

Atherosclerotic renovascular disease (ARVD) refers to atheromatous narrowing of one or both renal arteries and frequently coexists with atherosclerotic disease in other vascular beds. Patients with this condition are at high risk of adverse cardiovascular events, with mortality around 8% per year. Many patients with ARVD have chronic kidney disease, but only a minority progress to endstage kidney disease, suggesting that pre-existing hypertensive and/or ischaemic renal parenchymal injury is the usual cause of renal dysfunction. Many patients with ARVD are asymptomatic, but there can be important complications such as uncontrolled hypertension, rapid decline in kidney function, and recurrent acute heart failure (flash pulmonary oedema). Management—patients with ARVD should receive medical vascular protective therapy just like other patients with atheromatous disease. This involves antiplatelet agents such as aspirin, statins, antihypertensive agents (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers are the drugs of choice), optimization of glycaemic control in diabetic patients, and advice/help to stop smoking. On the basis of randomized controlled trial data, they should not be offered revascularization by angioplasty/stenting for the purpose of improving blood pressure control or stabilizing/improving renal function. However, there is evidence that a subgroup of patients with specific complications of ARVD (as previously mentioned) may benefit from revascularization.

Atherosclerotic Renovascular Disease

Introduction In this study, we investigate whether the addition of biomarkers to a model based on traditional risk factors improves risk prediction and patient selection for revascularization in atherosclerotic renovascular disease. Methods Patients in the Salford Renovascular Study who had the following biomarkers analysed on a baseline sample were included in this study: FGF-23, Cystatin C, kidney injury molecule-1, myeloperoxidase, neutrophil gelatinase-associated lipocalin, N-terminal prohormone of brain natriuretic peptide (NT-proBNP), high-sensitivity Troponin T and anti-apolipoprotein A1 IgG. Cox proportional hazards models and net reclassification index were used to study the effects of either individual or a panel of biomarkers on predicting death, end-stage kidney disease and cardiovascular events. Results A total of 112 patients were followed up for a median 59.9 months (IQR 33.6–86.9). In total, 75 patients died, 21 reached end-stage kidney disease and 36 suffered a cardiovascular event. Only NT-proBNP maintained a statistically significant association with all end-points (death: HR 1.62 [95% CI 1.26–2.10], P < 0.0005; end-stage kidney disease: HR 1.51 [95% 1.19–1.91], P = 0.001; cardiovascular event: HR 1.56 [95% CI 1.23–1.97], P < 0.0005). Risk reclassification improved with addition of all biomarkers as a panel to the base model. Only patients with NT-proBNP concentrations above 300 ng/L gained benefit from revascularization with regard to all adverse end-points compared with medically managed patients. Conclusions NT-proBNP is independently associated with increased risk for all adverse events in atherosclerotic renovascular disease. Novel biomarkers may have an incremental risk predictive value when used in combination with traditional risk factors, and NT-proBNP may have value in patient selection for revascularization. Given the small size of this study, larger multicentre studies are required to validate these findings.

Pathology Of The Liver

Introduction: Combined heart-liver transplant (CHLT) is indicated for patients with end-stage heart failure and concomitant irreversible liver injury. Given that liver dysfunction from congestive hepatopathy is common in patients with end-stage heart failure, it can be difficult to determine reversible from irreversible liver injury. Transjugular liver biopsy (TJLB) is frequently used to evaluate the severity of parenchymal injury, but is limited by heterogeneity of fibrosis across biopsy specimens. We sought to compare the fibrosis evaluation of the TJLB specimens as compared to the pathology of the liver explant at the time of CHLT. Methods: All CHLT cases at CSMC between 2007 and 2017 were included. Demographic and liver ultrasound (US) or abdominal computed tomography (CT) imaging was retrieved by chart review. TJLB was performed prior to transplant to determine the severity of liver fibrosis and was compared to the pathology of the liver explant. A biopsy was considered to show heterogenous fibrosis if there was at least a 2 stage difference between the predominant and secondary patterns. Results: Thirteen CHLTs were performed at our center during the study period. The median follow-up was 59 months (IQR 48-67). Mean age at transplant was 53 years (SD +/- 14.9) and 77% of patients were male. Indications for CHLT included cardiac cirrhosis (7), amyloidosis (2), HCV cirrhosis (2), and congenital heart disease (2). By imaging, 3/7 patients (43%) had US and CT evidence, 2/7 (29%) had US or CT evidence, and 2/7 (29%) had no evidence of liver nodularity US or CT. All patients diagnosed with cardiac cirrhosis had both TJLB and explant pathology for review. All TJLBs were graded as stage 4 fibrosis. Fibrosis on analysis of the liver explant was variable: stage 4 (2), stage 3-4 (3), stage 2-4 (1), and stage 1-4 (1). Thus, 2/7 patients (29%) showed heterogeneity of fibrosis in their explant as compared to their TJLB. Conclusions: We found heterogeneity of fibrosis in liver explants of patients that had stage 4 fibrosis (cirrhosis) by TJLB and underwent CHLT. Further work is needed to identify which heart transplant candidates will most benefit from CHLT.

Egfr Decline

Introduction: Among individuals with impaired kidney function, whether and when angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) should be discontinued is unclear. We investigated the associations of ACE-I/ARB discontinuation with end-stage kidney disease (ESKD), major adverse cardiovascular events (MACE), and mortality in individuals who had an eGFR decline to below 30 ml/min/1.73m 2 . Hypothesis: Patients with ACE-I/ARB discontinuation after an eGFR decline to below 30 ml/min/1.73m 2 are at higher risks of ESKD, MACE, and mortality. Methods: Using electronic health records data from the Geisinger Health System, we identified individuals who initiated ACE-I/ARB between 01/01/2004 and 02/28/2019 and had an eGFR decline to below 30 ml/min/1.73m 2 . We classified patients based on whether they discontinued ACE-I/ARB within six months following the eGFR decline. We assessed the associations of ACE-I/ARB discontinuation with ESKD, MACE, and mortality over the subsequent five years in a propensity-score matched sample. Results: Among the 3879 patients who met eligibility criteria, 1219 discontinued ACE-I/ARB within six months after eGFR decline to below 30 ml/min/1.73m 2 . The propensity-score matched sample contained 1190 patients under each arm. ACE-I/ARB discontinuation was associated with higher risks of mortality (hazard ratio (HR): 1.45 [95% confidence interval (CI): 1.26-1.67]) and MACE (HR: 1.37 [95% CI: 1.20-1.57]), but no significant difference in risk of ESKD (HR: 1.31 [95% CI: 0.95-1.81]). Similar patterns held when evaluating ACE-I/ARB discontinuation following a 40% or greater decline in eGFR within a year. Conclusions: Our findings suggest there may be benefits of continued use of ACE-I/ARB in individuals who had an eGFR decline to below 30 ml/min/1.73m 2 .

Background: Dapagliflozin reduces the risk of end-stage renal disease in patients with chronic kidney disease. We examined the relative risk of cardiovascular and kidney events in these patients and the effect of dapagliflozin on either type of event, taking account of history of cardiovascular disease. Methods: In the DAPA-CKD trial (Dapagliflozin And Prevention of Adverse Outcomes in Chronic Kidney Disease), 4304 participants with chronic kidney disease were randomized to dapagliflozin 10 mg once daily or placebo. The primary endpoint was a composite of sustained decline in estimated GFR ≥50%, end-stage kidney disease, or kidney or cardiovascular death. The secondary endpoints were a kidney composite outcome (primary endpoint, minus cardiovascular death), the composite of hospitalization for heart failure or cardiovascular death and all-cause death. In a prespecified subgroup analysis, we divided patients into primary and secondary prevention subgroups according to history of cardiovascular disease. Results: Secondary prevention patients (n=1610; 37.4%) were older, more often male, had a higher blood pressure and body-mass index, and were more likely to have diabetes. Mean estimated glomerular filtration rate and median urinary albumin-to-creatinine ratio was similar in the primary and secondary prevention groups. The rates of adverse cardiovascular outcomes were higher in the secondary prevention group, but kidney failure occurred at the same rate in the primary and secondary prevention groups. Dapagliflozin reduced the risk of the primary composite outcome to a similar extent in both the primary (HR, 0.61 [95% CI, 0.48-0.78]) and secondary (0.61, 0.47-0.79) prevention groups (P-interaction=0.90). This was also true for the composite of heart failure hospitalization or cardiovascular death (0.67, 0.40-1.13 versus 0.70, 0.52-0.94, respectively, P-interaction=0.88), and all-cause (0.63, 0.41-0.98 versus 0.70, 0.51-0.95, respectively, P-interaction=0.71). Rates of adverse events were low overall and did not differ between patients with and without cardiovascular disease. Conclusions: Dapagliflozin reduced the risk of kidney failure, death from cardiovascular causes or hospitalization for heart failure, and prolonged survival, in people with chronic kidney disease, with or without type 2 diabetes, independently of the presence of concomitant cardiovascular disease Clinical Trial Registration: URL: https://clinicaltrials.gov Unique Identifier: NCT03036150
