In this randomized trial, the discontinuation of renin–angiotensin system inhibitors in patients with advanced chronic kidney disease did not lead to a significant between-group difference in the long-term rate of decline in the eGFR.

Among patients with recent MI, therapy with a polypill containing aspirin, ramipril, and atorvastatin led to a lower incidence of major adverse cardiovascular events at a median of 3 years than usual care.

In a randomized trial, 5661 patients with acute myocardial infarction and a reduced left ventricular ejection fraction, pulmonary congestion, or both were assigned to receive either sacubitril–valsartan or ramipril. At a median of 22 months, there was no significant difference between the two groups in the incidence of death from cardiovascular causes or incident heart failure.

The angiotensin receptor–neprilysin inhibitor LCZ696 was compared with the ACE inhibitor enalapril in patients with advanced heart failure. LCZ696 was superior to enalapril in all outcomes. Neprilysin inhibition may replace ACE inhibition for the treatment of heart failure. Angiotensin-converting–enzyme (ACE) inhibitors have been the cornerstone of the treatment for heart failure and a reduced ejection fraction for nearly 25 years, since enalapril was shown to reduce the risk of death in two trials. 1 , 2 Long-term treatment with enalapril decreased the relative risk of death by 16% among patients with mild-to-moderate symptoms. 2 The effect of angiotensin-receptor blockers (ARBs) on mortality has been inconsistent, 3 , 4 and thus, these drugs are recommended primarily for patients who have unacceptable side effects (primarily cough) while receiving ACE inhibitors. Subsequent studies showed that the use of beta-blockers and mineralocorticoid-receptor antagonists, when added to ACE . . .

In this trial in persons with chronic kidney disease and type 2 diabetes, combination therapy with finerenone and empagliflozin led to a greater reduction in the urinary albumin-to-creatinine ratio than either drug alone.

Angiotensin receptor blockers (ARB) and angiotensin converting enzyme (ACE) inhibitors are known to reduce proteinuria. Their combination might be more effective than either treatment alone, but long-term data for comparative changes in renal function are not available. We investigated the renal effects of ramipril (an ACE inhibitor), telmisartan (an ARB), and their combination in patients aged 55 years or older with established atherosclerotic vascular disease or with diabetes with end-organ damage. The trial ran from 2001 to 2007. After a 3-week run-in period, 25 620 participants were randomly assigned to ramipril 10 mg a day (n=8576), telmisartan 80 mg a day (n=8542), or to a combination of both drugs (n=8502; median follow-up was 56 months), and renal function and proteinuria were measured. The primary renal outcome was a composite of dialysis, doubling of serum creatinine, and death. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00153101. 784 patients permanently discontinued randomised therapy during the trial because of hypotensive symptoms (406 on combination therapy, 149 on ramipril, and 229 on telmisartan). The number of events for the composite primary outcome was similar for telmisartan (n=1147 [13·4%]) and ramipril (1150 [13·5%]; hazard ratio [HR] 1·00, 95% CI 0·92–1·09), but was increased with combination therapy (1233 [14.5%]; HR 1·09, 1·01–1·18, p=0·037). The secondary renal outcome, dialysis or doubling of serum creatinine, was similar with telmisartan (189 [2·21%]) and ramipril (174 [2·03%]; HR 1·09, 0·89–1·34) and more frequent with combination therapy (212 [2·49%]: HR 1·24, 1·01–1·51, p=0·038). Estimated glomerular filtration rate (eGFR) declined least with ramipril compared with telmisartan (−2·82 [SD 17·2] mL/min/1·73 m 2 vs −4·12 [17·4], p<0·0001) or combination therapy (−6·11 [17·9], p<0·0001). The increase in urinary albumin excretion was less with telmisartan (p=0·004) or with combination therapy (p=0·001) than with ramipril. In people at high vascular risk, telmisartan's effects on major renal outcomes are similar to ramipril. Although combination therapy reduces proteinuria to a greater extent than monotherapy, overall it worsens major renal outcomes. Boehringer-Ingelheim.

In this study, patients with type 2 diabetes, albuminuria, and mild-to-moderate renal dysfunction received losartan followed by lisinopril or placebo. The study was stopped early because of increased risks of hyperkalemia and acute kidney injury with combination therapy. Diabetic nephropathy is the leading cause of end-stage renal disease (ESRD) in the United States. 1 Persons with diabetes and proteinuria are at high risk for progression to ESRD. 2 Blockade of the renin–angiotensin system decreases the progression of proteinuric kidney disease, 3 – 5 and the degree of reduction in proteinuria correlates with the extent to which the decrease in the glomerular filtration rate (GFR) is slowed. 2 , 6 Given these observations, it has been hypothesized that interventions that further lower proteinuria will further reduce the risk of progression. 6 Combination therapy with an angiotensin-converting–enzyme (ACE) inhibitor and an angiotensin II–receptor blocker (ARB) results in . . .

In a multicenter placebo-controlled study, patiromer, a nonabsorbable potassium binder, led to a reduction in serum potassium levels in patients with chronic kidney disease and hyperkalemia who were receiving renin–angiotensin–aldosterone system (RAAS) inhibitors. Hyperkalemia is associated with life-threatening cardiac arrhythmias and increased mortality. 1 Patients at the highest risk for hyperkalemia are those with stage 3 or higher chronic kidney disease, with or without diabetes or heart failure, who are being treated with drugs that inhibit renal potassium excretion, particularly inhibitors of the renin–angiotensin–aldosterone system (RAAS). 1 – 4 Outpatient treatment of hyperkalemia is limited by the lack of effective agents. 4 Sodium polystyrene sulfonate and calcium polystyrene sulfonate may cause serious gastrointestinal adverse events 5 – 8 as well as less serious gastrointestinal side effects that may be difficult for patients to tolerate, which together typically limit their . . .

This study aimed to determine whether early administration of drugs that block the renin–angiotensin system slows the progression of change in glomerular mesangial fractional volume and retinopathy progression of two steps or more, according to the retinopathy severity scale. Early blockade of the renin–angiotensin system did not modify nephropathy progression in patients with type 1 diabetes but had important effects in slowing retinopathy. Early blockade of the renin–angiotensin system did not modify nephropathy progression in patients with type 1 diabetes but had important effects in slowing retinopathy. Diabetic nephropathy, responsible for more than 45% of cases of end-stage renal disease in the United States, 1 may be structurally advanced once albuminuria becomes detectable. 2 , 3 Blockers of the renin–angiotensin system are more effective than other antihypertensive agents in slowing nephropathy progression in patients who have proteinuria, diabetes mellitus, and a reduced glomerular filtration rate (GFR), 4 – 6 and such blockers can also decrease proteinuria in patients with diabetes. 7 Although the reduction of proteinuria in patients with diabetes has been associated with a reduction in the rate of decline in GFR in small studies, 8 this association has not been systematically tested; . . .

Studies have challenged the appropriateness of accepted blood pressure targets. We hypothesised that different levels of low blood pressure are associated with benefit for some, but harm for other outcomes. In this analysis, we assessed the previously reported outcome data from high-risk patients aged 55 years or older with a history of cardiovascular disease, 70% of whom had hypertension, from the ONTARGET and TRANSCEND trials investigating ramipril, telmisartan, and their combination, with a median follow-up of 56 months. Detailed descriptions of randomisation and intervention have already been reported. We analysed the associations between mean blood pressure achieved on treatment; prerandomisation baseline blood pressure; or time-updated blood pressure (last on treatment value before an event) on the composite outcome of cardiovascular death, myocardial infarction, stroke, and hospital admission for heart failure; the components of the composite outcome; and all-cause death. Analysis was done by Cox regression analysis, ANOVA, and χ2. These trials were registered with ClinicalTrials.gov, number NCT00153101. Recruitment for ONTARGET took place between Dec 1, 2001, and July 31, 2008. TRANSCEND took place between Nov 1, 2001, and May 30, 2004. 30 937 patients were recruited from 733 centres in 40 countries and followed up for a median of 56 months. In ONTARGET, 25 127 patients known to be tolerant to angiotensin-converting-enzyme (ACE)-inhibitors were randomly assigned after a run-in period to oral ramipril 10 mg/day (n=8407), telmisartan 80 mg/day (n=8386), or the combination of both (n=8334). In TRANSCEND, 5810 patients who were intolerant to ACE-inhibitors were randomly assigned to oral telmisartan 80 mg/day (n=2903) or placebo (n=2907). Baseline systolic blood pressure (SBP) 140 mm Hg or higher was associated with greater incidence of all outcomes compared with 120 mm Hg to less than 140 mm Hg. By contrast, a baseline diastolic blood pressure (DBP) less than 70 mm Hg was associated with the highest risk for most outcomes compared with all DBP categories 70 mm Hg or more. In 4052 patients with SBP less than 120 mm Hg on treatment, the risk of the composite cardiovascular outcome (adjusted hazard ratio [HR] 1·14, 95% CI 1·03–1·26), cardiovascular death (1·29, 1·12–1·49), and all deaths (1·28, 1·15–1·42) were increased compared with those in whom SBP was 120–140 mm Hg during treatment (HR 1 for all outcomes, n=16099). No harm or benefit was observed for myocardial infarction, stroke, or hospital admission for heart failure. Mean achieved SBP more accurately predicted outcomes than baseline or time-updated SBP, and was associated with the lowest risk at approximately 130 mm Hg, and at 110–120 mm Hg risk increased for the combined outcome, cardiovascular death, and all-cause death except stroke. A mean DBP less than 70 mm Hg (n=5352) during treatment was associated with greater risk of the composite primary outcome (HR 1·31, 95% CI 1·20–1·42), myocardial infarction (1·55, 1·33–1·80), hospital admission for heart failure (1·59, 1·36–1·86) and all-cause death (1·16, 1·06–1·28) than a DBP 70–80 mm Hg (14 305). A pretreatment and mean on-treatment DBP of about 75 mm Hg was associated with the lowest risk. Mean achieved SBP less than 120 mm Hg during treatment was associated with increased risk of cardiovascular outcomes except for myocardial infarction and stroke. Similar patterns were observed for DBP less than 70 mm Hg, plus increased risk for myocardial infarction and hospital admission for heart failure. Very low blood pressure achieved on treatment was associated with increased risks of several cardiovascular disease events. These data suggest that the lowest blood pressure possible is not necessarily the optimal target for high-risk patients, although it is not possible to rule out some effect of reverse causality.
