This Week in Cardiology: AI Adjudication, Bleeding Risk, and Digital Care
Systematic review suggests modest risk reduction with SGLT2 inhibitors or ARNIs added to standard therapy in severe heart failure.
Moderate evidence supports adding SGLT2 inhibitors to heart failure treatment
This systematic review and network meta-analysis evaluated adding SGLT2 inhibitors or angiotensin receptor-neprilysin inhibitors to neurohor…
A large analysis suggests adding SGLT2 inhibitors may lower risk of death or hospitalization for heart failure, though caution is advised.
Meta-Analysis Identifies Risk Factors for Adverse Outcomes in MINOCA Patients
Old heart risk rules fail for this specific chest pain mystery
A meta-analysis of 12,081 patients with myocardial infarction with non-obstructive coronary arteries (MINOCA) found that older age, diabetes…
New data shows that standard heart risk factors do not predict outcomes for patients with heart attacks and clear arteries.
Beta-blockers show no mortality benefit in MI patients with preserved ejection fraction
Beta-blockers do not lower death risk for heart attack patients with strong heart pumps
This meta-analysis of 23,524 adults with myocardial infarction and left ventricular ejection fraction ≥ 40% found that beta-blockers did not…
A large review found beta-blockers did not reduce death or heart failure in adults with heart attacks and normal heart function.
ICE-guided trans-septal puncture reduces fluoroscopy time and radiation dose in AF ablation or LAAO procedures
New imaging tool cuts radiation and time for heart rhythm patients
This systematic review and meta-analysis evaluated patients undergoing atrial fibrillation ablation or left atrial appendage occlusion. Intr…
A large review shows using intracardiac echocardiography during heart procedures reduces radiation exposure and fluoroscopy time without inc…
Meta-analysis finds invasive therapy reduces MI and revascularization in elderly NSTEMI patients
Older Heart Attack Patients Do Better With Stents But Face Bleeding Risks
This systematic review and meta-analysis of 2997 elderly patients with NSTEMI found that invasive therapies, compared with medical therapy, …
New data shows stents help older heart attack patients avoid repeat events but do not lower overall death rates compared to medicine alone.
Systematic review and meta-analysis shows adjunctive SVCI reduces AF recurrence but increases minor complications in AF ablation.
Adding SVCI to AF ablation lowers recurrence but raises minor complication risk
This systematic review and meta-analysis of randomized trials evaluated adjunctive superior vena cava isolation (SVCI) plus pulmonary vein i…
A meta-analysis of trials found that adding superior vena cava isolation to standard ablation reduced rhythm recurrence in adults, though mi…
Meta-analysis shows VOM ethanol infusion improves sinus rhythm maintenance in persistent AF ablation
Ethanol infusion improves rhythm control in persistent AF
This meta-analysis evaluated VOM ethanol infusion versus PVI with or without linear ablation in patients undergoing catheter ablation for pe…
Adding ethanol to standard ablation helps more people with persistent AF stay in sinus rhythm during the first year.
Meta-analysis finds conduction system pacing reduces heart failure hospitalizations in HFmrEF
New pacing method cuts hospital stays for heart failure patients with mildly reduced function
This systematic review and meta-analysis of 1867 patients with heart failure with mildly reduced ejection fraction (HFmrEF) found that condu…
A new pacing method reduced hospital visits for heart failure patients with mildly reduced function compared to standard care.
Meta-analysis finds Cimlanod does not reduce mortality in HFrEF, increases hypotension risk
Cimlanod did not reduce death in heart failure patients
This meta-analysis of 459 patients with HFrEF found that Cimlanod did not significantly reduce all-cause or cardiac mortality compared to pl…
A meta-analysis of heart failure patients found Cimlanod did not lower death risk and increased the chance of low blood pressure symptoms.
Cryoballoon ablation reduces PV automaticity retention compared to radiofrequency ablation in PAF
Ablation times differ but rhythm return looks the same for both methods
This RCT in 100 patients with paroxysmal atrial fibrillation undergoing initial catheter ablation found that cryoballoon ablation (CBA) resu…
Two common heart rhythm procedures show similar success rates for stopping fast beats, even though one takes longer and uses more X-ray time…
Vericiguat showed no significant effect on flow-mediated dilation in a small pilot trial of 26 heart failure patients.
Pilot trial shows vericiguat may lower heart failure blood pressure markers
This pilot, randomized, double-blind, placebo-controlled trial enrolled 26 patients with heart failure with reduced ejection fraction (HFrEF…
A small pilot trial found vericiguat reduced a heart failure blood pressure marker, though the study was too small to confirm this benefit.
Nurse-led care coordination fails to improve medication adherence in high-need patients
Nurse-led care coordination did not improve medication adherence for most common chronic conditions.
This pragmatic randomized controlled trial tested nurse-led care coordination versus usual care in high-need, high-cost commercially insured…
A large trial found that nurse-led care coordination did not improve how often people took their diabetes, heart, or thyroid medications com…
