🩸 Drop aspirin after 12 months? A-CLOSE says: not so fast. In 3,203 high-ischemic-risk patients after drug-eluting stenting, clopidogrel alone was noninferior to extended DAPT for net clinical events (5.0% vs 5.1%). But beneath that reassuring composite was a striking trade-off: ischemic events were higher with clopidogrel alone (3.7% vs 1.6%; HR 2.33), while bleeding was lower (1.8% vs 4.1%; HR...

🫁 Stable—but not safe. Should we intervene before patients crash? PRAGUE-26 randomized 558 patients with intermediate-high–risk acute pulmonary embolism to catheter-directed low-dose alteplase + anticoagulation or anticoagulation alone. The 7-day composite of death, recurrent PE, or cardiorespiratory decompensation/collapse fell from 6.8% to 0.7% (RR 0.10; P

🫀 Cut the Signal, Cut the Risk? Could pulmonary-artery denervation change the trajectory of heart failure–related pulmonary hypertension? In PADN-HF-PH, 264 symptomatic patients were randomized to denervation + guideline-directed medical therapy or medical therapy alone. Clinical worsening at 2 years: 25.7% vs 51.5% (HR 0.49; P=0.006). ⚡ A provocative concept: pulmonary sympathetic overactivity...

🧬 Could semaglutide do more than treat obesity and diabetes? A fascinating study in aged female mice suggests that late-life semaglutide may act partly as a calorie-restriction mimetic —improving cognition, physical function and glucose control while attenuating multiple hallmarks of ageing. 🐭⏳ Most strikingly, median lifespan increased from 742 to 834 days . The biology implicates nutrient sen...

🫀 Should we start a statin after age 70? STAREE delivers an important answer. In 9,971 adults ≥70 without cardiovascular disease, diabetes, or dementia, atorvastatin 40 mg reduced major cardiovascular events by  30% over 5.9 years (HR 0.70; NNT 37). 💊 Yet it did  not prolong disability-free survival (HR 0.94). The benefit was driven largely by fewer myocardial infarctions and coronary revascular...

🌍 The Monk, the Manuscripts, the Medical Bridge How did Arabic medical knowledge reach medieval Europe? 📚🩺 Meet Constantine the African (c. 1010–1087) —North African physician, multilingual translator, and Benedictine monk at Monte Cassino.

🫀 Atherosclerosis doesn't wait for middle age. In the REACT study of 16,808 adults without known ASCVD, silent plaque was found in 57.1% overall—and even in 8.7% of men and 6.7% of women aged 18–29. Plaque burden rose dramatically with age and increasingly involved multiple arterial territories. 🚨 Even more provocative: conventional 10-year risk classification identified only a minority with exi...

🫀 AF + just one stroke-risk factor: anticoagulate or not? The SINGLE-AF randomized trial tackled this common clinical gray zone. At 24 months, the composite of stroke, systemic embolism, major bleeding, or cardiovascular death occurred in 0.5% with a DOAC vs 1.5% without anticoagulation (HR 0.31; P=0.03). 🎯 ⚠️ Only 17 primary events occurred, so the effect estimate remains imprecise. Anticoagula...

🫀 MI has been redefined—and the numbers are gone. The Fifth Universal Definition of Myocardial Infarction (2026) replaces the familiar numerical MI types with a clinically intuitive trio: 🔴 Primary MI — acute coronary pathology 🟢 Secondary MI — supply–demand imbalance from another acute illness 🔵 Procedure-related MI — complication of a cardiac procedure The crucial message? 🩸 Troponin elevat...

🫀💊 Can 4 doses help protect the kidney after cardiac surgery? MERCURI-2 randomized 784 patients to perioperative dapagliflozin or placebo. AKI within 7 days fell from 52% to 28% —RR 0.54, an absolute reduction of ~24% and NNT ≈4. 📉 Intriguingly, the signal was driven largely by urine-output–defined AKI; creatinine-only AKI was unchanged. Hard 30-day outcomes were also unchanged. 🎙️ A provocativ...

💉 Shingles Shot, Heart Shield? 🛡️❤️ Could recombinant shingles vaccination protect more than the skin? In a natural experiment involving >72,000 matched adults ≥60 years, the recombinant vaccine was associated with 9% lower cardiovascular disease burden over 7 years , including lower burdens of ischemic heart disease and heart failure. 📉🫀 💡 Intriguingly, AS01-induced immune reprogramming and r...

🔎 Can you believe that meta-analysis? Meta-analyses sit near the summit of evidence-based medicine—but pooling more studies does not automatically produce more truth. 📊 Lee and colleagues offer a powerful clinical lesson: credibility requires alignment of evidence, methods, and inference . Ask first: Should these studies have been pooled at all? 🧠 Look for prospective planning, robust source da...

🩺 Avicenna: Medicine, Mind & a Millennium of Influence Nearly 1,000 years ago, Ibn Sina—Avicenna—was already asking questions that still animate medicine: How should we observe disease? How do reason and experience guide diagnosis? How are mind and body connected? 🧠 His monumental Canon of Medicine traveled from the Islamic world into European universities and influenced generations of physician...

🎯 Target the Tumor, Guard the Heart! ❤️ Antibody-drug conjugates are transforming breast cancer therapy—but precision oncology does not eliminate cardiovascular risk. 🧬🫀 This excellent JACC: CardioOncology Primer explores how the antibody, linker & payload may contribute to cardiotoxicity.

🎨 Repigment, Reframe, Restore: A New Era for Vitiligo Vitiligo is far more than a cosmetic condition. In two phase 3 Viti-Up trials, oral upadacitinib 15 mg significantly improved facial and total-body repigmentation at 48 weeks. 💊 But here is the deeper lesson: better pigmentation ≠ complete patient benefit. Only 13–15% reported their vitiligo as "a lot less" or "no longer" noticeable. 👁️ The f...

🧬 Detect, Decode, Decide: The Promise of Liquid Biopsy Can a blood test tell us what cancer is doing before imaging can? 🩸 Circulating tumor DNA (ctDNA) can identify actionable variants, track treatment response, detect resistance, and reveal molecular residual disease. In colorectal cancer, molecular relapse was detected ~8.7 months earlier than with imaging surveillance. 🔬 But important quest...

🩺 Great Doctors Series: Rhazes (c. 865–925 CE) More than 1,000 years ago, Persian physician Rhazes (Al-Razi) practiced a remarkably modern kind of medicine: observe the patient, question authority, compare outcomes, and care for everyone—rich or poor. 🔬 He distinguished smallpox from measles , pioneered writing on childhood disease , challenged Galen when observations disagreed, and profoundly i...

⚡ Short Sprints, Big Signals: How Exercise Intensity Changes the Message Exercise may be more than movement—it may be an interorgan conversation. 🧬🫀 A fascinating human multi-omics study shows that sprint-interval exercise produces broader and faster changes in circulating proteins and metabolites than moderate-intensity exercise.
