Aggressive approach and outcome in patients presenting atrial fibrillation and hypertension

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Atrial fibrillation (AF) and hypertension are common cardiovascular conditions.
• Effective management of AF, particularly in hypertensive patients, is crucial for improving patient outcomes.
• Rhythm control and reducing hospital admissions are key goals in AF management.

Purpose of the Study:

• To evaluate the effectiveness of an aggressive pharmacological and electrical approach in patients with atrial fibrillation and hypertension.
• To compare rhythm conversion rates and hospital admission reductions between standard and aggressive treatment strategies.
• To identify predictors of successful rhythm conversion and hospitalization in this patient cohort.

Main Methods:

• A comparative study involving 1739 hypertensive patients with AF, divided into standard (n=591) and aggressive (n=1148) treatment groups.
• The aggressive group received enhanced pharmacological and electrical interventions.
• Primary endpoint was rhythm conversion; secondary endpoints included conversion modalities and admission rates.

Main Results:

• The aggressive approach significantly improved overall rhythm conversion rates from 55% to 62% (p=0.018).
• In patients with AF duration less than 48 hours, rhythm conversion was achieved in 89%, with a preference for class 1C antiarrhythmic drugs.
• Hospital admissions were reduced by 60%, with 29% of patients in the aggressive group requiring admission versus 50% in the standard group (p<0.001).

Conclusions:

• An aggressive treatment strategy for AF in hypertensive patients significantly enhances rhythm conversion.
• Early intervention in AF (duration < 48 hours) with class 1C antiarrhythmics is highly effective for achieving sinus rhythm.
• This aggressive approach leads to a substantial reduction in hospital admissions, improving overall patient management.
