Thread 'Fluoroless Pulsed Field Ablation of Atrial Fibrillation'

Feb 15, 2025

Mansour Razminia, MD, a cardiac electrophysiologist at Northwestern Medicine, discusses the innovative technique of fluoroless pulsed field ablation (PFA) for treating atrial fibrillation. He explains how this ultra-rapid electrical field safely disrupts targeted cardiac tissues, leading to effective treatment outcomes with minimal collateral damage. Dr. Razminia also highlights Northwestern Medicine's recent success with the procedure and introduces the retrospective MANIFEST-US survey designed to assess the acute efficacy and safety of the FARAWAVE™...

Thread 'Lifestyle and Atrial Fibrillation'

Mar 29, 2024

Could that cup of coffee or glass of wine change your cardiac risk? At this Medical Grand Rounds, we will present the latest evidence regarding the impact of common habits like alcohol and caffeine consumption on cardiac arrhythmias. In addition to exploring the clinical and lifestyle implications of our findings, we will describe some of the pioneering research methods we’re employing at UCSF to better understand the impact of lifestyle on heart health.

Thread 'Atrial Fibrillation: Guideline Update for Primary Care'

Apr 27, 2024

I'm Dr Neil Skolnik. Today we are going to talk about the 2023 American College of Cardiology/American Heart Association guidelines for atrial fibrillation (AF). AF is common and is often first identified in the primary care office. AF substantially increases the risk for stroke, dementia, myocardial infarction, and heart failure.

When AF is detected, three areas of care need to be addressed: symptoms, stroke risk, and modifiable lifestyle factors. Patients with AF should have an echocardiogram done as well as laboratory tests (CBC, CMP...

* It is likely a U shape therapeutic curve with the lowest incidence of occuring at men with mid-range values of concentrations (350-550 ng/dL)

Analysis of the Graph

The graph shows a U-shaped relationship between testosterone levels and atrial fibrillation (AF) risk:

Lowest risk: Around 10-20 nmol/L (nadir of the curve)
Increased risk: Both low (<10 nmol/L) and high (>30 nmol/L) testosterone levels
The study followed 4,570 Australian men for a median of 4.3 years

* Together, these observations add an important piece to the complex puzzle of how sex hormones influence atrial electrophysiology. In this context, the principle “dosis sola facit venenum” (the dose makes the poison) resonates strongly, suggesting that apparent discrepancies between studies may not be contradictory, but rather reflect different positions along the testosterone spectrum which seems to be non-linear.

* our meta-analysis stands as the most up to date analysis restricted to RCTs directed to men aged 40 or older.

* The main fndings were as follows: (1) there were no significant diferences between groups in all-cause mortality, cardiovascular mortality, MI, and stroke; (2) TRT signifcantly increased the incidence of cardiac arrhythmias; (3) TRT was associated with decreased levels of HDL-c; and (4) there was a marginal increase in SBP levels in the TRT group.
