What is Atrial Fibrillation — DOAC Selection?

Direct oral anticoagulants (DOACs) are now preferred over warfarin in non-valvular atrial fibrillation for stroke prophylaxis. Available agents include the thrombin inhibitor dabigatran and the factor Xa inhibitors rivaroxaban, apixaban and edoxaban.

Anticoagulation is indicated when the CHA2DS2-VASc score is ≥2 in men or ≥3 in women (≥1 in men, ≥2 in women per current European recommendations). Each DOAC has a distinct dosing schedule, renal-clearance profile and drug-interaction profile that guide individualised selection.

Symptoms

Paroxysmal, persistent or permanent atrial fibrillation
CHA2DS2-VASc score that meets the threshold for anticoagulation
Prior stroke or transient ischaemic attack (secondary prevention)

Risk Factors

Advanced age
Hypertension
Diabetes mellitus
Heart failure
Vascular disease
Previous stroke or TIA

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When deciding on anticoagulation at the time of AF diagnosis
  • When DOAC dosing must be adjusted to renal function
  • When a bleeding complication develops
  • When checking for clinically relevant drug interactions

Treatment Methods

01
Apixaban 5 mg twice daily — lowest bleeding risk in most analyses
02
Rivaroxaban 20 mg once daily with food — single-dose convenience
03
Dabigatran 150 mg twice daily — strongest stroke protection but more GI bleeding
04
Edoxaban 60 mg once daily
05
Dose reduction in renal impairment (CrCl <50 mL/min)
06
Annual renal-function review and bleeding-risk reassessment

Hypertension is a condition in which blood pressure readings remain above 140/90 mmHg; early treatment helps prevent serious complications.

Coronary Artery Disease

Kardiyoloji

Narrowing of the coronary arteries due to atherosclerosis can cause chest pain (angina) and heart attack.

Heart Failure

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial Fibrillation

Kardiyoloji

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
