Insights
Anticoagulation in acute coronary syndrome (ACS) patients with atrial fibrillation (AF) reduces mortality and ischemic stroke. Guideline-recommended therapy in this population is associated with better outcomes.
Area of Science:
- Cardiology
- Clinical Research
- Public Health
Background:
- Increasing prevalence of atrial fibrillation (AF) in acute coronary syndrome (ACS) patients.
- Lack of data on anticoagulation outcomes in ACS patients with AF.
Purpose of the Study:
- Investigate stroke, myocardial infarction, bleeding, and mortality rates in ACS patients with AF.
- Evaluate the impact of anticoagulation on these outcomes.
Main Methods:
- Analysis of the PL-ACS and AMI-PL registries (n=13,973).
- Selection of ACS survivors with AF, divided by anticoagulation use.
- 12-month follow-up with propensity score matching.
Main Results:
- Anticoagulation (17.6% of patients) was associated with lower all-cause mortality, myocardial infarction, and ischemic stroke.
- No significant increase in bleeding events observed.
- Matched analysis confirmed similar positive outcomes.
Conclusions:
- Guideline-recommended anticoagulation in ACS survivors with AF is linked to reduced mortality and ischemic events.
- This national registry analysis supports the use of anticoagulation in this high-risk group.
Abstract:
The prevalence of atrial fibrillation (AF) in acute coronary syndrome (ACS) patients is increasing. Data on outcomes of anticoagulation in ACS patients with AF are lacking.
Abstract:
The aim of our study was to investigate the prevalence of stroke, myocardial infarction, bleeding complications, and all-cause mortality in this population.
Abstract:
PL-ACS and AMI-PL registries gather an all-comer population of ACS patients in Poland, exceeding half a million records. We have selected ACS survivors with concomitant AF on admission, divided them into subgroups with regard to the administered anticoagulation, and followed up with them for a 12-month period (n = 13,973). Subsequently, groups were propensity score matched for age, sex, ejection fraction, diabetes, heart failure, renal impairment, and type of ACS.
Abstract:
The study population was divided with regard to the administration of anticoagulation. Anticoagulation was prescribed in 2,466 patients (17.6%). The (D)OAC+ patients were younger; however, comorbidities were more prevalent in this group. The 12-month follow-up showed that the (D)OAC+ patients had significantly lower rates of all-cause mortality, myocardial infarction, and ischemic stroke, with no significant increase in bleeding events. After matching, the study groups consisted of 2,194 patients each and showed no differences in baseline characteristics. The outcomes of the 12-month observation were similar to the findings before matching.
Abstract:
This all-comer national registry analysis shows that the use of guideline-recommended therapy and anticoagulation in ACS survivors with AF is associated with a lower rate of all-cause mortality, recurrent myocardial infarction, and ischemic stroke.

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
