Latest guidelines for Anti-hypertensives👇

According to American Heart Association (2025) and European Society of Cardiology (2024) HTN guidelines:

Start meds at ≥130/80 if high risk.

First-line = ACEi/ARB + CCB + thiazide.
Prefer 2-drug single pill combos. Target SBP 120-129. #Hypertension

Understanding RA/CVP Waveforms Made Easy

This diagram breaks down the different waves and descents seen in right atrial (RA) or central venous pressure (CVP) tracings and links them to what’s happening in the heart.

Here’s what you’ll learn:
1️⃣ ‘a’ wave: caused by right atrial contraction. It's absent in atrial fibrillation and very large in conditions like tricuspid stenosis or junctional rhythms.
2️⃣ ‘c’ wave: from tricuspid valve bulging into the RA during early systole.
3️⃣ ‘v’ wave: due to passive filling of the RA. It becomes prominent in tricuspid regurgitation.
4️⃣ ‘x’ descent: shows atrial relaxation. It’s deeper in constrictive pericarditis, but less in TR and RV dysfunction.
5️⃣ ‘y’ descent: represents early ventricular filling. It’s sharp in constrictive pericarditis and blunted in tamponade.

Guidelines for the administration of sodium bicarbonate (7.5%) in various medical scenarios, detailing dosage, method, and important precautions.

Do not mix with calcium, catecholamines, or NS; use caution in low ionized calcium, fluid overload, CHF, and early phase DKA (if pH < 6.9).

There is no formal, internationally recognised definition of ‘high’ neuraxial blockade.

Symptoms:
• cardiovascular instability
• weakness of the upper limbs
• respiratory compromise
• collapse

AHA 2025 CPR ECC Guidelines：Overview
https://t.co/VI5SoMLWJB
The 2025 AHA guidelines introduce significant practice changes to address persistently low cardiac arrest survival rates. With only 10.5% of out-of-hospital cardiac arrest (OHCA) patients surviving to discharge, urgent action is required. These updates emphasize that poor outcomes typically stem from educational gaps or implementation failures rather than guideline quality itself, according to the Utstein Formula.
