Personalized Care for Atrial Fibrillation: Focusing on Lifestyle Modifications may Reduce Risk
The heart condition known as atrial fibrillation, often shortened to "AFib," is a common and difficult-to-manage irregular heartbeat that affects an estimated 33.5 million people worldwide. This condition, characterized by an erratic beating of the left upper heart chamber (atrium), can lead to serious complications like stroke.
Beyond the widely recognized risk factors impacting cardiovascular health, such as physical activity, obesity, and smoking, the presence of chronic conditions like diabetes, hypertension, respiratory and mental health issues also heighten the risk for AFib.
According to a recent review published in the journal, numerous lifestyle factors, comorbid conditions, and socioeconomic factors contribute to the risk of AFib. This comprehensive review underscores the importance of multidisciplinary, individualized care for effective management of AFib and the reduction of related deaths and other health conditions.
Dr. Stephen Tang, a board-certified cardiac electrophysiologist from Providence Saint John's Health Center, explained the complex nature of AFib management in an interview with Medical News Today: "The comprehensive management of AFib goes well beyond oral anticoagulation for stroke prevention or rate or rhythm control with medication or ablation. This complex disease is driven by numerous risk factors and comorbidities."
Nonmodifiable risk factors for AFib include genetics, sex, and age, while specific lifestyle choices, comorbid conditions, and socioeconomic factors can also increase the risk. To manage this condition, a combination of lifestyle changes, blood thinners, and medications targeting cardiac rhythms may be necessary, along with invasive procedures like catheter ablation to restore a normal heart rhythm.
Physical activity plays a key role in AFib risk management. Regular exercise and high-intensity interval training have been shown to reduce the risk of AFib and improve patients' quality of life. In contrast, a sedentary lifestyle is associated with an increased risk. Maintaining a healthy weight through diet and exercise is essential, as obesity is another significant risk factor for AFib.
Smoking and excessive alcohol consumption are additional risk factors, while the impact of moderate alcohol consumption on the risk of AFib is still unclear. Sleep apnea is an especially important comorbid factor, as the disrupted breathing patterns associated with this condition may lead to the formation of blood clots and contribute to the structural and electrical changes in the heart that characterize AFib. Managing sleep apnea with continuous positive airway pressure (CPAP) machines can help reduce the risk of AFib and related complications.
Cardiovascular, respiratory, metabolic, and mental health conditions also increase the risk of AFib, and their proper management can help reduce the risk of complications and death. For example, improving blood pressure control has a significant impact on reducing the risk of AFib.
Since individuals with AFib often have multiple chronic health conditions, the use of multiple medications increases the risk of adverse events, especially in the case of polypharmacy (the use of five or more prescription drugs). Nonvitamin K antagonist oral anticoagulants have fewer adverse effects than warfarin and are becoming the first-line treatment for AFib patients.
Various demographic and ethnic factors can influence the risk of AFib, with mixed results. While some studies suggest that South Asian and African descents have a lower risk of AFib compared to white populations, others indicate a higher risk. Regarding biological sex, men are more likely to develop AFib, but women are at a higher risk of complications like stroke and mortality, due in part to differences in access to healthcare and psychosocial factors.
Dr. Nikhil Warrier, a board-certified cardiac electrophysiologist, emphasized the need for individualized care, explaining, "Due to the role of a multitude of factors, including lifestyle choices, comorbid conditions, genetics, and socioeconomic factors, a multidisciplinary approach that is tailored for a particular patient is needed."
Achieving optimal AFib management remains challenging due to the plethora of risk factors and the difficulty in implementing lifestyle modifications. As Dr. Yehoshua Levine, a cardiologist, noted, "Optimal management of AFib is very patient-dependent and necessarily involves consideration of multiple clinical, socioeconomic, and demographic factors, which are all important in determining the most appropriate treatment approach."
