Impact of sacubitril/valsartan on implantable defibrillator eligibility in heart failure: a real-world experience.

OBJECTIVE: Current guidelines recommend an implantable cardiac defibrillator (ICD) in patients with symptomatic heart failure and reduced ejection fraction (HFrEF; left ventricular ejection fraction [LVEF] ≤35%) despite ≥3 months of optimal medical therapy. Recent observations demonstrated that sacubitril/valsartan induces beneficial reverse cardiac remodeling in eligible HFrEF patients. Given the pivotal role of LVEF in the selection of ICD candidates, we sought to assess the impact of sacubitril/valsartan on ICD eligibility and its predictors in HFrEF patients. PATIENTS AND METHODS: We retrospectively evaluated 48 chronic HFrEF patients receiving sacubitril/valsartan and previously implanted with an ICD in primary prevention. We assumed that ICD was no longer necessary if LVEF improved >35% (or >30% if asymptomatics) at follow-up. RESULTS: Over a median follow-up of 11 months, sacubitril/valsartan induced a significant drop in LV end-systolic volume (-16.7 ml/m2, p=0.023) and diameter (-6.8 mm, p=0.022), resulting in a significant increase in LVEF (+3.9%, p<0.001). As a consequence, 40% of previously implanted patients resulted no more eligible for ICD at follow-up. NYHA class improved in 50% of the population. A dose-dependent effect was noted, with higher doses associated to more reverse remodeling. Among patients deemed no more eligible for ICD, lower NYHA class (odds ratio (OR) 3.73 [95% CI 1.05; 13.24], p=0.041), better LVEF (OR 1.23 [95% CI 1.01; 1.48], p=0.032) and the treatment with the intermediate or high dose of sacubitril/valsartan (OR 5.60 [1.15; 27.1], p=0.032) were the most important predictors of status change. CONCLUSIONS: In symptomatic HFrEF patients, sacubitril/valsartan induced beneficial cardiac reverse remodeling and improved NYHA class. These effects resulted in a significant reduction of patients deemed eligible for ICD in primary prevention.

Hypertension and kidneys: unraveling complex molecular mechanisms underlying hypertensive renal damage.

Kidney damage represents a frequent event in the course of hypertension, ranging from a benign to a malignant form of nephropathy depending on several factors, that is, individual susceptibility, degree of hypertension, type of etiology and underlying kidney disease. Multiple mechanisms are involved in determination of kidney glomerular, tubular and interstitial injuries in hypertension. The present review article discusses relevant contributory molecular mechanisms underpinning the promotion of hypertensive renal damage, such as the renin-angiotensin-aldosterone system (RAAS), oxidative stress, endothelial dysfunction, and genetic and epigenetic determinants. We highlighted major pathways involved in the progression of inflammation and fibrosis leading to glomerular sclerosis, tubular atrophy and interstitial fibrosis, thus providing a state of the art review of the pathogenetic background useful for a better understanding of current and future therapeutic strategies toward hypertensive nephropathy. An adequate control of high blood pressure, obtained through an appropriate therapeutic intervention, still represents the key strategy to achieve a satisfactory control of renal damage in hypertension. In this regard, we reviewed the impact of currently available antihypertensive pharmacological treatment on kidney damage, with particular regard to RAAS inhibitors. Notably, recent findings underscored the ability of the kidneys to regenerate and to repair tissue injuries through the differentiation of resident embryonic stem cells. Pharmacological modulation of the renal endogenous reparative process (that is, with angiotensin-converting enzyme inhibitors and AT1 angiotensin II receptor blockers), as well as future therapeutic strategies targeted to the renopoietic system, offers interesting perspectives for the management of hypertensive nephropathy.
