Selected Articles
1. Finerenone in Persons with Chronic Kidney Disease without Diabetes.
In FIND-CKD, a randomized, double-blind trial in 1,584 adults with CKD but without diabetes, finerenone slowed the decline in eGFR versus placebo over 32 months. This extends mineralocorticoid receptor antagonist benefits beyond diabetic CKD.
Impact: First high-quality RCT to show renal benefit of finerenone in CKD without diabetes, potentially expanding indications and informing guideline updates.
Clinical Implications: Finerenone may be considered to slow kidney function decline in adults with CKD without diabetes, pending regulatory and guideline alignment; monitoring and patient selection strategies should be defined.
Key Findings
- Randomized 1,584 adults with CKD and no diabetes to finerenone vs placebo.
- Finerenone slowed the decline in eGFR over 32 months compared with placebo.
- Baseline mean eGFR was 46.8 mL/min/1.73 m2; effects observed across the randomized population.
Methodological Strengths
- Randomized, double-blind, placebo-controlled design
- Pre-specified primary kidney function slope outcome over a long follow-up (32 months)
Limitations
- Abstract reports eGFR slope benefit; detailed hard kidney endpoints (e.g., ESKD) are not specified in the provided text
- Generalizability across CKD etiologies requires further subgroup detail
Future Directions: Define optimal patient selection, safety monitoring, and impact on hard renal outcomes and cardiovascular endpoints in non-diabetic CKD; cost-effectiveness and implementation studies are warranted.
BACKGROUND: In randomized trials, finerenone, a nonsteroidal mineralocorticoid receptor antagonist, improved kidney and cardiovascular outcomes in patients with type 2 diabetes and chronic kidney disease (CKD). Whether finerenone has similar effects in patients without diabetes who have CKD is unknown. METHODS: We randomly assigned adults without diabetes who had CKD (estimated glomerular filtration rate [eGFR], 25 to <90 ml per minute per 1.73 m RESULTS: A total of 1584 participants underwent randomization - 793 were assigned to the finerenone group, and 791 to the placebo group. The mean (±SD) baseline eGFR was 46.8±16.2 ml per minute per 1.73 m CONCLUSIONS: Among adults with CKD who did not have diabetes, finerenone led to a slower decrease in the eGFR than placebo over 32 months.

2. P2Y12 inhibitor monotherapy after abbreviated dual antiplatelet therapy following percutaneous coronary intervention: a meta-analysis.
Across 11 RCTs (n=37,443), switching to P2Y12 inhibitor monotherapy after ≤1 or 3 months of DAPT maintained MACE rates and reduced bleeding versus 12-month DAPT. Very early aspirin discontinuation (<1 month) increased stent thrombosis in ACS.
Impact: Provides timing-specific, trial-based evidence to personalize antiplatelet de-escalation after PCI, balancing bleeding reduction against stent thrombosis risk in ACS.
Clinical Implications: Consider P2Y12 monotherapy after 1–3 months of DAPT to reduce bleeding while maintaining ischemic protection; avoid very early (<1 month) aspirin discontinuation in ACS or high ischemic risk patients due to stent thrombosis concerns.
Key Findings
- No significant MACE difference vs 12-month DAPT when aspirin discontinued at ≤1 or 3 months.
- Major and major/minor bleeding significantly reduced with both ≤1-month and 3-month discontinuation; greater reduction with ≤1-month.
- In ACS sensitivity analysis, very early aspirin discontinuation (<1 month) increased stent thrombosis risk (RR 1.81).
Methodological Strengths
- Prospectively registered (PROSPERO) meta-analysis of RCTs with both pairwise and network methods
- Consistent findings across analyses; sensitivity analysis in ACS clarified thrombosis signal
Limitations
- Trial-level meta-analysis; patient-level modifiers (lesion complexity, stent type) not uniformly captured
- Heterogeneity in DAPT durations, P2Y12 agents, and bleeding definitions across trials
Future Directions: Patient-level meta-analyses and RCTs stratified by ischemic/bleeding risk (including ACS phenotypes and stent platforms) to refine timing of aspirin discontinuation.
BACKGROUND AND AIMS: After percutaneous coronary intervention (PCI), growing evidence supports P2Y12 inhibitor monotherapy after a short course of dual antiplatelet therapy (DAPT) as a safer and equally effective antiplatelet strategy compared with continued DAPT. However, the optimal timing of aspirin discontinuation remains uncertain. METHODS: A systematic review and meta-analysis of randomized controlled trials investigating different timings of aspirin discontinuation after a short course of DAPT in PCI patients, compared with continued DAPT, was conducted. Pairwise random-effects and network meta-analyses were performed. The primary endpoint was major adverse cardiovascular events (MACE). Secondary endpoints included major bleeding, major or minor bleeding, net adverse cardiovascular events (NACE), all-cause death and myocardial infarction. The study was registered in PROSPERO (CRD420251140207). RESULTS: Eleven randomized trials including 37,443 patients were identified. In pairwise analyses, compared with 12-month DAPT, there were no significant differences in the risk of MACE with aspirin discontinuation at either ≤1 month (risk ratio [RR] 1.01; 95% confidence interval [CI] 0.85-1.20) or 3 months (RR 0.95; 95% CI 0.67-1.36), with no significant differences between discontinuation timings. Both major and major or minor bleeding were significantly reduced with ≤1-month (RR 0.46; 95% CI 0.23-0.94; P = 0.038 and RR 0.43; 95% CI 0.36-0.51; P < 0.001, respectively) and 3-month (RR 0.59; 95% CI 0.39-0.89; P = 0.027 and RR 0.57; 95% CI 0.53-0.60; P = 0.005, respectively) discontinuation, with a more pronounced reduction in major or minor bleeding with ≤1-month discontinuation (P = 0.044 for interaction). NACE was significantly reduced with ≤1-month discontinuation, and no significant differences between discontinuation timings emerged. Network meta-analyses yielded consistent results, and for major or minor bleeding, the indirect comparison showed superiority of ≤1-month over 3-month aspirin discontinuation (RR, 0.75; 95% CI, 0.57-0.99; P = 0.044). In a sensitivity analysis restricted to acute coronary syndromes, early aspirin discontinuation was associated with a higher risk of stent thrombosis (RR 1.81; 95% CI 1.15-2.84; P = 0.019), with the excess risk observed mainly with very early aspirin discontinuation (<1 month). CONCLUSIONS: Aspirin discontinuation at either ≤1 or 3 months with continued P2Y12 inhibitor monotherapy is associated with similar MACE, lower bleeding, and lower NACE compared with continued DAPT. Discontinuation within the first month may confer additional bleeding benefit, but at the cost of excess stent thrombosis, particularly in patients at higher ischaemic risk.
3. Predicting lifetime cardiovascular risk and benefits of preventive treatment in patients with established atherosclerotic cardiovascular disease: the SMART-REACH2 model.
SMART-REACH2, derived in 8,708 patients and externally validated in 2,085,780 patients across 54 countries, achieved adequate calibration and C-statistics (pooled 0.68) across risk regions and sexes. It estimates lifetime recurrent ASCVD risk and treatment benefits, including gains in CVD-free life expectancy.
Impact: Provides a globally recalibrated, externally validated lifetime risk tool for secondary prevention, enabling shared decision-making on intensifying BP and LDL-C lowering.
Clinical Implications: Use SMART-REACH2 to estimate short-term and lifetime recurrent ASCVD risk and quantify treatment benefits; supports communicating potential gains in CVD-free life expectancy tailored to geographic region and sex.
Key Findings
- Derivation in 8,708 patients; external validation in 2,085,780 patients from 54 countries.
- Pooled C-statistic 0.68 with adequate calibration across diverse risk regions; performance consistent by sex and CVD subtype.
- Estimated gains in CVD-free life expectancy with intensified prevention ranged from ~2.0 to 4.4 years depending on regional risk.
Methodological Strengths
- Cause-specific Cox modeling with age as timescale; sex-stratified modeling using routinely available predictors
- Extensive external validation (54 countries) with systematic regional recalibration and robust calibration assessment
Limitations
- Moderate discrimination (C-statistic ~0.68) typical of clinical risk models
- Implementation requires accurate regional recalibration data and may need updates with changing epidemiology
Future Directions: Prospective impact analyses, EHR integration, and calibration maintenance; evaluation of added biomarkers or imaging to improve discrimination.
BACKGROUND AND AIMS: The 2021 ESC guidelines on cardiovascular (CV) disease prevention recommend the SMART-REACH lifetime risk model to guide treatment decisions in patients with established atherosclerotic CV disease. The aim was to develop the SMART-REACH2 model for estimating lifetime risk of recurrent CV events and treatment benefits in patients with established atherosclerotic CV disease, with systematic recalibration to the four European and other global risk regions. METHODS: SMART-REACH2 was derived in 8708 individuals aged 40-90 years with coronary, cerebrovascular, peripheral artery disease and/or abdominal aortic aneurysm from the UCC-SMART cohort. Sex-stratified, cause-specific Cox models for recurrent CV events and non-CV death were fitted using age as timescale and routinely available predictors. Recurrent CV events were defined as a composite of myocardial infarction, stroke, or CV death. Recalibration was based on representative cohorts per risk region. External validation was performed in 2 085 780 patients from 54 countries; model performance was assessed by calibration plots and Harrell's C-statistic. RESULTS: In the derivation cohort, 2057 recurrent CV events occurred over a median follow-up of 8.5 years (25th-75th: 4.3-13.0). In external validation, 307 706 events occurred. The pooled C-statistic was 0.68 (95% confidence interval 0.66-0.69) and ranged from 0.66 (0.64-0.69) for European low-risk region up to 0.72 (0.66-0.78) for Latin America, with adequate calibration across risk regions. Performance was consistent across sexes and CV disease subtypes. Using SMART-REACH2, estimated potential gains in CV disease-free life expectancy for a 50-year-old example patient receiving intensified preventive treatment (15 mmHg systolic blood pressure and 1.0 mmol/L low-density lipoprotein cholesterol reduction) ranged from 2 years in the low-risk region to 4.4 years in the very-high-risk region. CONCLUSIONS: The updated SMART-REACH2 model accounts for geographical and sex-specific variations and allows estimation of short-term and lifetime risk of recurrent CV events and treatment benefits, facilitating shared decision-making as recommended by guidelines.
