💊 Can SGLT2 inhibitors improve outcomes in transthyretin cardiac #Amyloidosis? A #JACCAdvances meta-analysis of 14 observational studies (n=10,852) found #SGLT2i use was associated with 56% lower all-cause mortality & 38% lower HF hospitalization. bit.ly/4sjrhPO

Large V-waves are common in HF patients, but their significance has been unclear. Here’s why it matters: they augment RV afterload independent of the lung vessels, with implications for how we assess pulmonary vascular disease. #HFSA2026 @CircAHA
Large V-waves are encountered often in HF patients, but unclear clinical significance. Borlaug et al. dig deeper. In ≈1100 HFpEF patients, prom. V-waves tracked w/ L-atrial myopathy, greater pulmonary hypertension,... #HFSA2026 ahajrnls.org/4s2fxRJ @yreddyhf @TChaikijurajai

This week, @CircAHA goes into space. @AppaduraiVinesh et al. followed 13 astronauts with echocardiography before and during spaceflight, a median of 164 days. Early reductions in LV chamber size and stroke volume occurred within 14 days, then returned toward normal with longer exposure. Good news for future long-term space expeditions: 6 months of microgravity did not appear to cause sustained abnormalities in LV cardiac structure or function. ahajournals.org/doi/full/10.… @AHAScience | #Cardiology #Spaceflight

Clinical Problem Solving: The management of ventricular tachycardia (VT) is rarely straightforward, and clinicians must consider all eventualities. In this week's @CircAHA Clinical Problem Solving section, Nielson et al. (@WilcoxHeart, @NishantVermaMD) discuss a real patient case with challenges and unexpected findings at every turn: a primer on the causes of VT, its treatment, and a few new lessons for us all.

Clinician Lighthouse: Patients often present with unexpected findings — including a newly discovered bundle branch block. New LBBB and RBBB interpretation has evolved, and it matters for every clinician, not just EPs. This week, Dr. Jeremy Treger et al. walk through a stepwise approach to diagnosis. Here's why it matters: in their case, a new LBBB meant an EF of 25%. After conduction, system pacing corrected it, EF normalized to 62%. A new BBB is a clue, not a final answer.

Inside the Journal: Cardiovascular disease doesn't respect borders. We're honored to have Dr. Ana Mocumbi join @CircAHA as our new Deputy Editor for Global Cardiovascular Health — her Perspective this week argues that tools like portable battery-powered ultrasound will drive key solutions. Here's why it matters: LMIC countries carry a growing share of global CV deaths but produce under 4% of the research. Ana also joined this week's #CircOnTheRun podcast — walked through her vision in a fantastic conversation, and yes, she speaks seven languages...

Editor's Perspective: The management of acute myocardial infarction is elemental to cardiovascular medicine. This week in @CircAHA, Marco Valgimigli (@vlgmrc) and colleagues lay out a state-of-the-art review spanning STEMI, NSTEMI, and MINOCA management. Here's why it matters: this paper summarizes where we are — and where we still need to go, including AI-supported diagnosis of occlusive MI, new thrombus management devices, and selective anti-inflammatory therapies.

Editor's Perspective: Two new papers in @CircAHA this week (@JKassabMD et al., B. Lindman et al.) show how often guideline-recommended echo follow-up for aortic stenosis — moderate and severe — gets missed, even as treatment options keep improving. Why it Matters: Proven treatments are available; the opportunity to use them on time appears to be missed.

Inside the Journal: Population health in cardiovascular medicine is moving fast. This week's Perspective from @MCarnethon, the new Deputy Editor for Population Health at @CircAHA, makes the case for chasing the "unusual" in cardiovascular disease. Here's why it matters: the uncommon and unexplained — an understudied population, a signal a wearable is already capturing — is where the next real insight is hiding. A good note to end #ESCCongress week on. Read her full Perspective: ahajournals.org/doi/full/10.… @American_Heart | #Circulation #PopulationHealth

It has been an immense privilege to lead this trial, and report on it at @escardio congress. All clinical trials are hard, investigator initiated trials even more so. Thank you to all investigators, trial staff, steering committee, DSMB, CEC and DDC members, and most of all patients and families who took part in the trial

Inside the Journal: Practice changing. Sometimes surprising. When well-designed, always informative. Our commitment to clinical trials takes shape today with a Perspective by @texhern. He outlines what we're looking for: relevance to real clinical decisions, reach into the populations where disease actually occurs, rapid learning through adaptive design, and rigor that never bends. This @CircAHA is ready to lead the way in cardiovascular clinical trial research. Read the Perspective: ahajournals.org/doi/full/10.… @American_Heart | #Cardiology #Circulation #ClinicalTrials

A New Era of @CircAHA: New chapter, new voices. Alongside @kejoynt and @HeartDocSadiya, I'm excited about where Circulation is headed — and why we want you to be part of it. Take a watch. We look forward to seeing many of you later this month at ESC Congress 2026 in Munich. @American_Heart | #Cardiology #Circulation #ESCCongress2026

Inside the Journal: Clinical research is the bedrock of progress in cardiovascular medicine. Hypothesis generating. Hypothesis testing. Moving basic science forward. Enabling clinical trial development. At @CircAHA, @JenHoCardiology and Dr. Ryan Tedford are the widely respected and deeply knowledgeable captains of this important mission. This week, they outline their vision of where clinical research is headed and establish our priorities on this critical topic at the journal. Their guiding standard: does a paper pass the "coffee table test" — will clinicians stop, read, discuss, and reconsider practice? Every submission gets weighed against three questions: Is it done well? Is it novel? Is it clinically actionable? The vision: clinical cardiology sits at the convergence of mechanisms of disease, therapeutic innovation, and systems and population impact — and the next era of discovery will come from connecting disciplines, not deeper silos.

Does extensive LGE on CMR in dilated cardiomyopathy = an ICD? Not necessarily. Our new @CircAHA Clinician Lighthouse discusses a practical approach to interpreting LGE and integrating it with LVEF, genotype, arrhythmias, and clinical context. #CMR bit.ly/4w1xcJn

3 practical lessons from our @CircAHA Clinician Lighthouse: 1️⃣ Recognise LGE pattern → Ischaemic or non-ischaemic? 2️⃣ Integrate risk → Consider LVEF, ventricular arrhythmias, genotype and family history. 3️⃣ shared decision with patient. LGE, in isolation may not = ICD.
