In a secondary analysis comparing the effect of insulin glargine, glimepiride, liraglutide, and sitagliptin, added to metformin, on the incidences of microvascular complications and death, no material between-group differences were seen.

Among patients hospitalized for acute myocardial infarction and at risk for heart failure, empagliflozin did not lead to a significantly lower risk of a first heart-failure hospitalization or death from any cause than placebo.

In a multicenter trial, 20,332 patients who had recently had an ischemic stroke were randomly assigned to receive either telmisartan or placebo. All patients also received medications for blood-pressure control at the investigators' discretion. At a mean follow-up of 2.5 years, there was no significant difference between the two study groups in the rates of recurrent stroke or major cardiovascular events. Patients who had recently had an ischemic stroke were randomly assigned to receive either telmisartan or placebo. At a mean follow-up of 2.5 years, there was no significant difference between the study groups in the rates of recurrent stroke or major cardiovascular events. Stroke is the second most frequent cause of death in the world and is responsible for about 5 million deaths each year. 1 An additional 15 million persons have nonfatal strokes, with about a third having disabling consequences. Elevated blood pressure is the strongest risk factor for stroke, and lowering of blood pressure, especially in patients with substantially elevated levels (e.g., systolic pressure, >160 mm Hg), reduces the risk of stroke. 2 After a stroke, lowering blood pressure with a combination of an angiotensin-converting–enzyme (ACE) inhibitor and a diuretic reduced rates of recurrent stroke in the Perindopril Protection against Recurrent Stroke Study . . .

Patients undergoing maintenance dialysis for kidney failure are at substantial risk of cardiovascular morbidity and mortality. We aimed to establish if spironolactone reduces heart failure and cardiovascular deaths in these patients. ACHIEVE was an international, parallel-group, randomised controlled trial done in 143 dialysis programmes in 12 countries. Patients were aged 45 years or older, or aged 18 years or older with a history of diabetes, and were receiving maintenance dialysis for kidney failure for at least 3 months at the time of recruitment. Patients who were able to tolerate and adhere to spironolactone 25 mg daily orally during an open-label run-in were randomly assigned (1:1) to continue spironolactone or matching placebo, using a central computerised block randomisation system (block sizes of 4) stratified by centre. Participants, health-care providers, and those assessing outcomes were masked to group assignment. The primary outcome was a composite of cardiovascular mortality or hospitalisation for heart failure analysed as time-to-event in all randomly assigned participants. The trial was registered at ClinicalTrials.gov, NCT03020303. After a planned interim analysis of 75% of the expected primary outcome events, the external safety and efficacy monitoring committee recommended the trial be stopped early for futility. From Sept 19, 2017, to Oct 31, 2024, 3689 patients were screened for inclusion, 3565 of whom were enrolled in the open-label run-in phase, and 2538 were randomly assigned to spironolactone (n=1260) or placebo (n=1278). 931 (36·7%) participants were female and 1607 (63·3%) were male. Median follow-up was 1·8 years (IQR 0·85–3·35). The composite primary outcome occurred in 258 participants (10·46 events per 100 patient-years) in the spironolactone group and in 276 participants (11·33 per 100 patient-years) in the placebo group (hazard ratio [HR] 0·92 [95% CI 0·78–1·09]; p=0·35). Death from any cause was similar between groups (HR 0·95 [0·83–1·09]) as was hospitalisation for any cause (HR 0·96 [0·87–1·06]). Among patients receiving maintenance dialysis, spironolactone 25 mg daily orally did not reduce the composite outcome of cardiovascular mortality and hospitalisation due to heart failure compared with placebo. This trial did not identify a benefit of initiating spironolactone in patients receiving maintenance dialysis.

Mineralocorticoid receptor antagonists have been shown to reduce mortality in patients after myocardial infarction with congestive heart failure. Whether routine use of spironolactone is beneficial after myocardial infarction is uncertain. In this multicenter trial with a 2-by-2 factorial design, we randomly assigned patients with myocardial infarction who had undergone percutaneous coronary intervention to receive either spironolactone or placebo and either colchicine or placebo. The results of the spironolactone trial are reported here. The two primary outcomes were a composite of death from cardiovascular causes or new or worsening heart failure, evaluated as the total number of events; and a composite of the first occurrence of myocardial infarction, stroke, new or worsening heart failure, or death from cardiovascular causes. Safety was also assessed. We enrolled 7062 patients at 104 centers in 14 countries; 3537 patients were assigned to receive spironolactone and 3525 to receive placebo. At the time of our analyses, the vital status was unknown for 45 patients (0.6%). For the first primary outcome, there were 183 events (1.7 per 100 patient-years) in the spironolactone group as compared with 220 events (2.1 per 100 patient-years) in the placebo group over a median follow-up period of 3 years (hazard ratio adjusted for competing risk of death from noncardiovascular causes, 0.91; 95% confidence interval [CI], 0.69 to 1.21; P = 0.51). With respect to the second primary outcome, an event occurred in 280 of 3537 patients (7.9%) in the spironolactone group and 294 of 3525 patients (8.3%) in the placebo group (hazard ratio adjusted for competing risk, 0.96; 95% CI, 0.81 to 1.13; P = 0.60). Serious adverse events were reported in 255 patients (7.2%) in the spironolactone group and 241 (6.8%) in the placebo group. Among patients with myocardial infarction, spironolactone did not reduce the incidence of death from cardiovascular causes or new or worsening heart failure or the incidence of a composite of death from cardiovascular causes, myocardial infarction, stroke, or new or worsening heart failure.

Among patients with myocardial infarction and a left ventricular ejection fraction of more than 40%, beta-blockers did not lead to a lower incidence of death, reinfarction, or hospitalization for heart failure than no beta-blocker therapy.

Purpose To test whether the polymyxin B hemoperfusion (PMX HP) fiber column reduces mortality and organ failure in peritonitis-induced septic shock (SS) from abdominal infections. Method Prospective, multicenter, randomized controlled trial in 18 French intensive care units from October 2010 to March 2013, enrolling 243 patients with SS within 12 h after emergency surgery for peritonitis related to organ perforation. The PMX HP group received conventional therapy plus two sessions of PMX HP. Primary outcome was mortality on day 28; secondary outcomes were mortality on day 90 and a reduction in the severity of organ failures based on Sequential Organ Failure Assessment (SOFA) scores. Results Primary outcome: day 28 mortality in the PMX HP group ( n  = 119) was 27.7 versus 19.5 % in the conventional group ( n  = 113), p  = 0.14 (OR 1.5872, 95 % CI 0.8583–2.935). Secondary endpoints: mortality rate at day 90 was 33.6 % in PMX-HP versus 24 % in conventional groups, p  = 0.10 (OR 1.6128, 95 % CI 0.9067–2.8685); reduction in SOFA score from day 0 to day 7 was −5 (−11 to 6) in PMX-HP versus −5 (−11 to 9), p  = 0.78. Comparable results were observed in the predefined subgroups (presence of comorbidity; adequacy of surgery, <2 sessions of hemoperfusion) and for SOFA reduction from day 0 to day 3. Conclusion This multicenter randomized controlled study demonstrated a non-significant increase in mortality and no improvement in organ failure with PMX HP treatment compared to conventional treatment of peritonitis-induced SS.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is common and occurs in 6–8% of all patients fulfilling the diagnostic criteria for acute myocardial infarction (AMI). This paper describes the rationale behind the trial ‘Randomized Evaluation of Beta Blocker and ACE-Inhibitor/Angiotensin Receptor Blocker Treatment (ACEI/ARB) of MINOCA patients’ (MINOCA-BAT) and the need to improve the secondary preventive treatment of MINOCA patients. MINOCA-BAT is a registry-based, randomized, parallel, open-label, multicenter trial with 2:2 factorial design. The primary aim is to determine whether oral beta blockade compared with no oral beta blockade, and ACEI/ARB compared with no ACEI/ARB, reduce the composite endpoint of death of any cause, readmission because of AMI, ischemic stroke or heart failure in patients discharged after MINOCA without clinical signs of heart failure and with left ventricular ejection fraction ≥40%. A total of 3500 patients will be randomized into four groups; e.g. ACEI/ARB and beta blocker, beta blocker only, ACEI/ARB only and neither ACEI/ARB nor beta blocker, and followed for a mean of 4 years. While patients with MINOCA have an increased risk of serious cardiovascular events and death, whether conventional secondary preventive therapies are beneficial has not been assessed in randomized trials. There is a limited basis for guideline recommendations in MINOCA. Furthermore, studies of routine clinical practice suggest that use of secondary prevention therapies in MINOCA varies considerably. Thus results from this trial may influence future treatment strategies and guidelines specific to MINOCA patients.

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.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of heart-failure admission among high-risk patients. However, most patients with valvular heart disease, including those undergoing transcatheter aortic-valve implantation (TAVI), have been excluded from randomized trials. We conducted this randomized, controlled trial in Spain to evaluate the efficacy of dapagliflozin (at a dose of 10 mg once daily) as compared with standard care alone in patients with aortic stenosis who were undergoing TAVI. All the patients had a history of heart failure plus at least one of the following: renal insufficiency, diabetes, or left ventricular systolic dysfunction. The primary outcome was a composite of death from any cause or worsening of heart failure, defined as hospitalization or an urgent visit, at 1 year of follow-up. A total of 620 patients were randomly assigned to receive dapagliflozin and 637 to receive standard care alone after TAVI; after exclusions, a total of 1222 patients were included in the primary analysis. A primary-outcome event occurred in 91 patients (15.0%) in the dapagliflozin group and in 124 patients (20.1%) in the standard-care group (hazard ratio, 0.72; 95% confidence interval [CI], 0.55 to 0.95; P = 0.02). Death from any cause occurred in 47 patients (7.8%) in the dapagliflozin group and in 55 (8.9%) in the standard-care group (hazard ratio, 0.87; 95% CI, 0.59 to 1.28). Worsening of heart failure occurred in 9.4% and 14.4% of the patients, respectively (subhazard ratio, 0.63; 95% CI, 0.45 to 0.88). Genital infection and hypotension were significantly more common in the dapagliflozin group. Among older adults with aortic stenosis undergoing TAVI who were at high risk for heart-failure events, dapagliflozin resulted in a significantly lower incidence of death from any cause or worsening of heart failure than standard care alone.
