Over 20 years ago, I watched 45 minutes of resuscitation end in silence. The weeks before were filled with subtle symptoms, easy to dismiss. Until they weren’t.
That experience never left. It provided #lessons
• Not all risk announces itself
• Delayed recognition is common
• #Medicine has limits
• Sitting with patients in uncertainty is part of the work
• Community outreach can increase awareness and change outcomes

JVP is the window to your heart.
Which of the following JVP patterns this patient has with h/o radiation, alcoholism, cirrhosis & chest trauma?
Likely diagnosis!
1: Alcoholic cardiomyopathy
2: Portal pulmonary hypertension
3: Radiation CMP
4: Constrictive pericarditis

Why do South Asians get type 2 diabetes at much lower body weights? The answer is in their fat cells.
These are fat cells from two young men with the same BMI. The South Asian man's are on the left. The white man's are on the right.
At the same BMI as white Europeans, South Asians carry more body fat, bigger fat cells, more liver fat, and higher insulin. Here is what the studies show.
1. Same BMI, much bigger fat cells.
In 29 South Asian and 18 white men, average age 27, BMI was 24 vs 23. Body fat was 22% vs 15%. The average belly fat cell was 3,491 vs 1,648 µm² in cross section. Treating the cells as spheres, that is about 3 times the volume of fat per cell on average. The samples in the image show an even larger difference. The larger the fat cells, the worse the insulin resistance. Visceral fat was the same in both groups.
2. Matched for age and BMI, still more insulin.
Asian Indians matched to white adults had similar fasting glucose but higher fasting insulin, and they cleared glucose about 40% less well on a clamp test (4.7 vs 7.5 mg/kg/min).
3. Fat cell size explains much of the insulin gap.
After adjusting for age, sex and BMI, South Asians had larger fat cells, liver fat of 9.9% vs 2.5%, and higher fasting insulin. Adjusting for fat cell size cut the insulin difference in half.
4. Lean and young.
Among 482 lean young adults, insulin resistance was 2 to 3 times more common in Asian Indians than in any other group. The men had about twice the liver fat of white men.
5. It starts in childhood.
South Asian children aged 8 to 11 in Britain were not heavier than white children, but their fasting insulin was 53% higher, with similar blood glucose.
My view: fat cells can only store so much. When they are full, they become insulin resistant and release more fat into the blood, and that fat ends up in the liver and muscle. Insulin rises to compensate. South Asians appear to reach that limit at a lower body weight.
For a South Asian person, a normal BMI does not mean normal metabolism. Fasting insulin, waist size and liver fat say more than weight.

Interactive case discussion.
Send your opinions on this case. 60ym, South Asian with uncontrolled LDL, no symptoms and no other CV risk factors. Got this cardiac CT. What would you do next? LCX and RCA have no Ca2+
Great weekend in Phoenix reconnecting with friends and sharing our team’s work at #HFSA2026. Proud to support trainee scholarship and collaboration in heart failure care.

🚨 Fifth Universal Definition of Myocardial Infarction (2026)
#ESC26 #ESCCongress #Guidelines #MyocardialInfarction

🫀 ESC HEART FAILURE GUIDELINES 2026 — WHAT HAS CHANGED?
The new ESC HF Guidelines bring major changes in classification, treatment, decompensation, devices and precision phenotyping.
🔹 1 | New HF classification
➡️ HFrEF: LVEF <50%
➡️ HFpEF: LVEF ≥50%
The previous HFmrEF category is removed.
🔹 2 | “Acute HF” → “Decompensated HF (DHF)”
Management focuses on identifying the trigger and rapidly assessing congestion, perfusion, BP, renal function and oxygenation.
🔹 3 | Smarter decongestion
IV loop diuretics remain first-line.
If response is inadequate, consider sequential nephron blockade with IV acetazolamide or oral hydrochlorothiazide.
Early urinary sodium assessment may help guide diuretic escalation.
🔹 4 | Treat before discharge
Once stabilized, initiate/optimize foundational therapy—including in-hospital SGLT2 inhibitor initiation.
After discharge, aim for rapid optimization, with uptitration generally every 1–2 weeks when tolerated.
🔹 5 | MRA therapy expands
MRAs now have a broader role across the EF spectrum, including selected patients with HFpEF.
And if EF improves?
➡️ Continue foundational therapy.
🔹 6 | HFpEF becomes increasingly treatable
Beyond SGLT2 inhibitors, treatment now includes broader use of MRAs and selected RAAS inhibition, alongside phenotype-driven management of comorbidities.
🔹 7 | CRT: refined selection and timing
CRT remains Class I A for symptomatic HFrEF with:
➡️ LVEF ≤35%
➡️ sinus rhythm
➡️ LBBB
➡️ QRS ≥150 ms
despite optimal foundational therapy.
In this strong electrical phenotype, CRT planning may begin alongside initiation of foundational therapy, with reassessment before implantation.
⚠️ Evidence remains insufficient to recommend conduction-system pacing as an alternative to CRT in HFrEF.
🔹 8 | ICD: more individualized
Primary prevention:
➡️ Ischaemic HFrEF, LVEF ≤35% → Class I
➡️ Non-ischaemic HFrEF, LVEF ≤35% → Class IIa
Consider competing mortality, comorbidities, frailty, life expectancy and patient preference.
🔹 9 | Obesity becomes a treatment target
In selected symptomatic HF with LVEF ≥45% and BMI ≥30 kg/m², semaglutide or tirzepatide should be considered to improve weight, symptoms, exercise capacity and QoL.
🔹 10 | Precision imaging & aetiology
The focus moves beyond EF toward identifying why the patient has HF, with greater roles for CMR, CT, nuclear imaging and genetic testing.
ATTR-CM therapy also expands to tafamidis, acoramidis and vutrisiran.
🔹 11 | Mitral TEER & haemodynamic monitoring
Mitral TEER receives a Class I recommendation in appropriately selected HFrEF with severe secondary MR despite optimized therapy/CRT.
Pulmonary artery pressure-guided monitoring is strengthened to Class IIa in selected high-risk patients.
📌 The ESC HF 2026 message:
Diagnose earlier → phenotype better → decongest effectively → start treatment early → titrate rapidly → personalize devices and interventions → prevent the next decompensation.
💡 HF management is becoming less about treating an EF number—and more about treating the individual patient’s phenotype, aetiology, haemodynamics and comorbidities.

📉⚡ Early + complete GDMT = best outcomes
The four pillars work fast 🚀 and work best together 🛡️
Simultaneous/rapid sequencing to all four components of quadruple GDMT at 🎯 doses (as well tolerated) should be the standard of care for all
