Personalized Care Focusing on Lifestyle Factors May Decrease AFib Risk: A New Approach for Patients
Atrial fibrillation, a common type of arrhythmia, affects more people worldwide than you might think. This irregular heart rhythm significantly increases the risk of stroke and other health problems.
In addition to the well-known risk factors connected to cardiovascular health, such as exercise, diabetes, obesity, and smoking, the presence of chronic conditions like cardiovascular, respiratory, metabolic, and mental health issues also raises the risk.
Research published in various journals has revealed that lifestyle factors, comorbid conditions, and socioeconomic factors can influence the risk of atrial fibrillation. This finding stresses the need for a multi-disciplinary, personalized approach to managing atrial fibrillation and reducing the risk of death and developing other health issues.
Dr. Stephen Tang, a board-certified cardiac electrophysiologist, explains, "The comprehensive management of atrial fibrillation goes 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. If these are not controlled, atrial fibrillation will continue to occur despite ablation. Identifying and optimizing these risk factors is crucial in managing atrial fibrillation long-term."
Genetic factors, sex, and age are nonmodifiable risk factors for atrial fibrillation. Other risk factors include lifestyle factors, comorbid conditions, and socioeconomic factors. Blood thinners (anticoagulants) can reduce the risk of blood clot formation and stroke. Nonvitamin K antagonist oral anticoagulants (NOACs) have become the first line of treatment for atrial fibrillation.
Lifestyle changes, such as regular exercise, weight loss, and smoking cessation, can help manage this heart condition. While studies support the role of exercise in reducing morbidity and improving quality of life for individuals with atrial fibrillation, the evidence supporting the role of exercise in preventing stroke is less clear.
Obesity, which is a major risk factor for atrial fibrillation, increases the likelihood of recurrence, complications during catheter ablation, stroke, and death. Smoking and moderate to heavy alcohol consumption are also risk factors for atrial fibrillation.
Individuals with chronic cardiovascular, respiratory, and mental health conditions are not only risk factors for atrial fibrillation but can also increase the complications associated with this condition. For example, obstructive sleep apnea, which occurs in 21-74% of atrial fibrillation patients, can increase the risk of blood clots and structural changes in the heart.
Managing sleep apnea using a continuous positive airway pressure (CPAP) machine can reduce the risk of atrial fibrillation incidence, recurrence, or progression.
Individuals with pre-existing cardiovascular conditions like coronary artery disease, hypertension, heart failure, and cardiomyopathies are at an increased risk of atrial fibrillation. Diabetes, a common comorbid condition, is associated with an increased risk of atrial fibrillation incidence and complications.
While high total cholesterol and low-density lipoprotein levels are risk factors for cardiovascular diseases, they are associated with a lower risk of atrial fibrillation. In contrast, higher levels of triglycerides are associated with an increased risk of atrial fibrillation.
Nearly half of all individuals with atrial fibrillation show impaired renal function, which can interfere with the metabolism of anticoagulant drugs, increasing the risk of adverse effects. COPD, a chronic lung condition, is linked to a twofold higher risk of atrial fibrillation.
Psychological factors like stress and depression are also associated with an increased risk of atrial fibrillation. Mental health conditions could potentially influence adherence to medications and increase the risk of interaction between drugs used for atrial fibrillation and mental health disorders.
Individuals with atrial fibrillation are more likely to have other comorbid conditions. These concomitant chronic health conditions, along with aging, can increase the risk of complications such as stroke and mortality in individuals with atrial fibrillation.
The presence of these coexisting chronic conditions requires the use of multiple medications that increase the risk of adverse effects. The use of five or more drugs is known as "polypharmacy," and is associated with the potential for drug-drug interactions and adverse events.
In terms of biological sex, atrial fibrillation is more prevalent in men than women, but women are at a higher risk of complications, including stroke and mortality. The higher risk of complications in women is attributed to differences in biological factors, access to healthcare, and psychological factors, such as stress.
Low socioeconomic status is also associated with an increased risk of heart failure, stroke, and mortality in individuals with pre-existing atrial fibrillation. Low socioeconomic status may influence access to healthcare, while lower health literacy can influence the patient's participation in treatment decisions.
Due to the role of a multitude of factors, a multidisciplinary approach that is tailored for a particular patient is needed. In other words, the care for atrial fibrillation must be individualized.
Explaining the need for individualized care, Dr. Nikhil Warrier, a board-certified cardiac electrophysiologist, noted, "The underlying risk factors that increase the likelihood of poor [AFib]-related outcomes can be different between every patient. For example, having a conversation that targets alcohol intake reduction and cessation in a patient for whom this is the primary trigger is different than someone who is sedentary, where starting an exercise program may be the conversation during the visit."
In conclusion, current evidence highlights a complex interplay of lifestyle factors, comorbid conditions, genetics, and socioeconomic factors in the risk of atrial fibrillation. Addressing modifiable lifestyle factors and optimizing management of comorbid conditions are central to reducing AF incidence and improving outcomes. Public health strategies should target both high-risk individuals and underserved populations to reduce disparities in AF burden and outcomes.
